Shallot is one of the priority agricultural commodities to be developed in Indonesia to reduce import and to stabilize domestic supply. The efforts include the selection of varieties, seed technology, agronomy, handling and processing to extend the supply and added value. Indonesian Agency for Agricultural Research and Development (IAARD) has purified, cross-pollinated, selected and released new varieties called New Superior Varieties (NSV) to farmers. The purpose of this research was to investigate the characteristic of fresh shallot NSV by understanding its potential for raw material of processed product. A completely randomized design (CRD) of single factor of ten local varieties of shallot such as Cv. Sembrani, Cv. Kuning, Cv. Pancasona, Cv. Bima, Cv. Trisula, Cv. Pikatan, Cv. Katumi, Cv. Kramat-2, Cv. Mentes and Cv. Majalok of three replication was used to arrange the experiment. The results showed that shallot New Superior Varieties (NSV) were significant by effect the physico-chemical parameters, such as diameter, length, weight of both in main bulb and tiller bulb, fat total, carbohydrate, crude fiber, starch content, antioxidant capacity and quercetin. Of the ten varieties of shallot characterized, the largest bulbs are Cv. Sembrani i.e 5.30 ± 0.3g per bulb, the best red color for shallot peeled was Cv. Kuning. Furthermore Cv. Pancasona have the highest protein content of 4.23 ± 0.2%, Cv. Mentes have the highest functional properties of quercetin 1766.4 ± 134 ppm. Shallot varieties such as Cv. Sembrani, Cv. Bima, Cv. Kuning and Cv. Trisula suitable for use as fresh product. Shallot varieties such as Cv. Pikatan, Cv. Pancasona, Cv. Katumi and Cv. Kramat-2 are suitable as raw materials for processed products. Cv. Mentes and Cv. Majalok were potential for raw materials of functional food and pharmaceutical industries.

TPK Sarimukti, Cipatat, West Bandung produced 2 kinds of compost from traditional market waste, liquid and solid compost. The aim of this research is to evaluate toxicity of compost produced in TPK Sarimukti using shallots (Allium cepa). Tests carried out by treated shallots with liquid compost (2,5%, 5%, 10% and 12,5% (w/v)) or solid compost (25%, 50%, 75% and 100% (w/v)) for 48 hours. Results showed reduced root growth rate and mitotic index (MI) in accordance with increased concentrations of compost. Sub lethal concentrations are liquid compost 5% and 10% and solid compost 75%. Lethal concentrations are liquid compost 12,5 % and solid compost 100%. Micronuclei (MN) increased with increase in liquid compost concentration. MN found at very high frequencies in highest solid compost concentration (100%), but very low at lower concentrations. Cells with binuclei and cell necrosis increased with increasing concentrations of given compost. Nuclear anomalies (NA) found in high frequency in 75% and 100% solid compost. Based on research, we can conclude that liquid compost is more toxic because it can reduce MI and root growth rate at lower concentrations than solid compost. Both types of compost have genotoxic properties because it can induce chromosome aberration (CA), MN, binuclei and NA formation.

In order to identify volatile organic compounds of fresh plants at room temperature and avoid sample pretreatment and extractions which can be labor intensive, garlic, Chinese chives and scallion were chopped into pieces. Then some of them were placed in the headspace vial and sealed. The gases were drawn from the vial with a syringe and were injected very slowly into Ag colloids for test using R-3000 portable Raman spectrometer. The spectra of volatile organic compounds of allium species, fresh garlic, Chinese chive and shallot plants were successfully.recorded for the first time. For garlic high intensity bands are present at 307, 399, 569, 711, 1,182, 1,287, 1,397 and 1,622 cm(-1). For Chinese chives the high intensity band is present at 672 cm(-1). Low intensity bands are present at 274, 412, 575, 1,185, 1,289, 1,396, 1,618 cm(-1). For shallot high intensity bands are present at 693 cm(-1). Lower intensity bands are present at 372, 888, 1,023 cm(-1). Low intensity bands are present at 1,088, 1,211 and 1,322 cm(-1). The SERS of diallyl disulfide, allyl methyl sulfide and 1-propanethiol in liquid state and gas state were also obtained. The main volatile organic compound of fresh garlic, Chinese chive and shallot are diallyl disulfide, allyl methyl sulfide and 1-propanethiol respectively, and the volatile organic compound of fresh onion, scallion, shallot and chive are all 1-propanethiol. The presented results illustrate that combining headspace and SERS is a powerful tool for volatile organic compound analysis in fresh plants. The volatile organic compound can be detected in fresh plant samples directly and quickly without extraction.

Shallots contains a lot of usefull ingredients for human life, especially as flavor to dishes by Indonesian. The need for shallots was increasing as increasing population. The increased demand of shallots caused the price to increase due to production in North Sumatera was low. The objective of this study is to analyze interest and factors that affect the interest of farmers in shallots farming and analyze the responses from each factors to the interest of farmers in shallots farming. The samples were 85 farmers in shallots farming. Binomial logit was used as data analysis method. The result of the study showed that the factors that influence the interest of farmers in shallots farming consist of land area, experience, income, supporting and trauma.. The opportunity of farmers in shallots farming increased 22% if the area of land increased by one acre. The probability variable with the supporting is higher 0,3 % compared without the supporting. While the probability variable without the trauma is higher 0,014 % compared with the trauma.

To optimize supply chain role, the players of supply chain need to integrate its function. One of the general problems in supply chain was the unbalanced quantity of sales and quantity of supply. This paper focused on modelling a simple method to manage the gap between the demand and the supply. The gap might cause an overstock or a loss. This paper propose a buffer quantity in order to handle the gap by using import decision. The case study was about shallot supply - demand in Indonesia. In this study we model the supply decisions of shallot in Indonesia. While the demand was quite stable over time, the supply was heavily affected by the yield from the farms. The shortage could result in the government importing shallot from other countries. Hence, the government also needed to have a proper buffering mechanism in order to ensure the supply was sufficient and the price was quite stable. The initial model of this research was built by stochastic parameters and the extended model to gain pricing mechanism was built by Shapley value principal with modification. The primary variables were supply quantity, demand quantity, buffer and purchased quantity (stock needed), actual consumption, and price for three players. The validation proved that the result of price at each player presented a significant difference. Therefore, the model could be applied to decide the stock quantity needed and to keep the price stable at each player especially at the end player which would influence the market price.

This research was conducted to investigate effects of ethanol vapour released in active packaging and storage temperatures on the quality of freshly peeled shallots. The package tested was a solid polypropylene tray incorporating an ethanol vapour-controlled release sachet. The sachet was made of an aluminium foil film on one side and either low-density polyethylene or nylon/polyethylene on the other. Individual sachets contained silica gel adsorbent as the carrier pre-loaded with ethanol. One sachet was placed in each tray containing the peeled shallots and the tray was heat sealed with the low-density polyethylene film lid. Packages were stored at either 10 or 25 ℃ for 10 d. Trays containing only peeled shallots were designated as controls. High storage temperature stimulated quality changes in the shallots. Although ethanol vapour accumulated in the active package headspace, the extent to which ethanol concentrations increased within the shallots was not significantly different from that in the control packages. Microbial proliferation in terms of yeast and mould counts could be delayed through a combination of 10 ℃ and ethanol vapour released from the low-density polyethylene sachet. The ethanol vapour accumulated in the packages did not have a significant effect on mass loss, firmness, and colour changes in the peeled shallots, or on the concentrations of oxygen and carbon dioxide in the packages.

Using seeds as planting materials is a solution to improve the quality and quantity of shallot. This study aims to determine the interaction between shallot varieties and Phosphate- Solubilizing Bacteria (PSB) on the flowering and shallot yield on the lowlands. The research was conducted in Mijil Village, Jaten, Karanganyar, 98 m altitude with Vertisol-type soil order in June to December 2016, using Randomized Complete Block Design (RCBD) with two factors. Shallot varieties used as factors are Bima, Manjung, Ilokos, Bima (bulb seeds), Mentes and Rubaru. PSB factors are control and with PSB inoculation. Observed variables included plant height, number of leaves, flowering percentage, seed formation and shallot bulb yield. Results showed that there was no interaction between varieties and PSB inoculation on all observed variables. However, PSB inoculation were able to increase the number of flowering plants and seed weight per plot. Bima variety have the highest average yield compared to other varieties in terms of number of leaves, number of bulbs per plant and bulb weight per plot (fresh harvest weight 317.74 g equivalent to 17.65 ton per hectare and dry weight 288.16 g consumption equivalent to 16 ton per hectare).

Persian leek is one of the most widely used herbal foods among Iranians. In this study, effects of oral administration of Persian leek on plasma and liver lipids were examined in hamster. Male Syrian hamsters were randomly divided into three groups: control (standard diet), high fat control (high-fat/high-cholesterol diet), Persian leek (high-fat/high-cholesterol diet + 1% per weight of diet from dried powdered Persian leek) for 14 weeks. High fat diet increased plasma and liver lipids as compared to standard diet. Adding Persian leek to the high-fat/high-cholesterol diet resulted in no significant changes in the concentration of the plasma lipids or liver cholesterol. However, liver triglycerides (TG), plasma Alanine aminotransferase and gene expression of tumor necrosis factor- α were decreased in hamsters fed high-fat diet containing Persian leek as compared to high-fat diet only. Persian leek might be considered as a herbal food that can reduce liver TG accumulation induced by high fat diets.

Shallot is one of horticultural commodities which has difficulties in flowering and producing seeds. Flowering of shallot generally occurs in highlands at 9-12° C. Flowering in lowland can be supported with vernalization or replace cold temperature with gibberelin (GA3). This research is aimed to determine the effect of varieties, the concentration of GA3 applied and their interaction on flowering and yield of shallots grown in the lowlands, 98 m altitude with Vertisol-type soil. The research was conducted in a randomized complete block design (RCBD) with two factors, which were varieties (V): Bima and Mentes and concentration of GA3 (C) 0 ppm, 50 ppm, 100 ppm, 150 ppm and 200 ppm and repeated three times. Varieties have significant effect (P<0.05) on plant height, leaf number, the number of bulbs per clumps, weight of fresh bulbs per clumps, and percentage of small and large bulbs produced. Bima varieties were able to flower and produced seeds, while Mentes varieties could not produce flowers and seeds. GA3 concentration have no significant effect in all of the observed component. GA3 can’t replace cold temperature for supported flowering in varieties Mentes which were planted in lowlands. There was interaction between varieties and GA3 concentration occurs in variable percentage of small and large bulbs.

The aim of the research was to study the variation in antioxidant and antimicrobial activity as well as the total quercetin content of the fifth generation genotypes mutant Samosir shallot irradiated by gamma rays. The studies conducted included the assessment of quercetin content, antioxidant and antimicrobial activity in shallot bulbs after long-term storage (6 months in the room temperature). Quercetin content of 20 selected genotype mutants of irradiated shallot bulbs along with untreated populations were calculated using quercetin (QU) as a standard. Antioxidant activities of 8 genotype mutant were determined using DPPH. Antimicrobial activity of bulb extracts were tested against six bacteria including Staphylococcus aurous, Enterococcus faecalis, Bacillus subtilis, Escherichia coli, Pseudomonas aeruginosa, and Klebsiella pneumoniae and oneyeastCandida albicans. The results showed that population of genotype mutants irradiated with dosage 2Gy, 4 Gy, 5 Gy and 6 Gy have higher quercetin content than control samples. None of the genotype mutants exhibited antibacterial inhibitory against all microorganism tested except for the sample number 2 and 6 (bulbs generated from the plants irradiated by gamma rays with dosage at 2 Gy and 6 Gy). There was also none of the genotypes observed exhibited significant antioxidant efficacy.

Leishmaniasis is caused by an obligate intracellular protozoa belonging to Leishmania genus. The current drugs for treatment of leishmaniasis possess many disadvantages; therefore, researchers are continuously looking for the more effective and safer drugs. The aim of this study is to review the effectiveness, toxicities, and possible mechanisms of pharmaceutical actions of different garlic extracts and organosulfur compounds isolated from garlic against Leishmania spp. in a variety of in vitro, in vivo and clinical trials reports. All relevant databases were searched using the terms “Allium sativum,” “Garlic,” “Allicin,” “Ajoene,” “Leishmania,” “in vitro,” “in vivo,” and “clinical trial,” alone or in combination from 5 English databases (Web of Science, PubMed, Science Direct, Scopus, Google Scholar) and 3 Persian databases (Scientific Information Database, Iran Medex, and Magiran) from 1990 to 2014. In summary, garlic with immunomodulatory effects and apoptosis induction contributes to the treatment of leishmaniasis. PMID:26721553

Shallot Aphids, Myzus ascalonicus, in Strawberry: Biocontrol Potential of Three Predators and Three Parasitoids

2013-01-01

The parasitization capacity of 3 parasitoids and the predation capacity of 3 predators towards the shallot aphid, Myzus ascalonicus Doncaster (Homoptera: Aphididae), on strawberry, Fragaria x ananassa Duchesne (Rosales: Rosaceae) cv. Honeoye, were examined in laboratory experiments. In Petri dish assays, both Aphidius colemani Viereck (Hymenoptera: Aphidiidae) and A. ervi Haliday readily stung shallot aphids, with no significant difference in stinging frequency between the two species. A. ervi induced a significantly higher mortality (79.0 ± 7.2%) in terms of stung aphids compared with A. colemani (55.3 ± 4.1%); however, only a minor fraction (2.7 ± 1.8% and 7.1 ± 3.1%, respectively) of the killed aphids resulted in formation of mummies, presumably due to a physiological response to parasitism. The low percentage of mummification precludes the use of either Aphidius species in anything but inundative biocontrol. In similar set-ups, Aphelinus abdominalis (Dalman) (Hymenoptera: Aphelinidae) killed almost half (49.6 ± 5.3%) of the exposed aphids through host feeding. In addition, 23.2 ± 7.3% of non-host-fed aphids developed into mummified aphids, and 38.1 ± 13.2% of non-host-fed aphids died from other parasitoid-induced causes. However, the host feeding rate was reduced to only 1.2 ± 0.8%, and no significant parasitization mortality was observed on strawberry plants, suggesting that host plants interfered with A. abdominalis activity. This parasitoid does not, therefore, seem to be suited to either inoculative or inundative biocontrol of shallot aphids in strawberry. The three predators studied were the green lacewing, Chrysoperla carnea Steph. (Neuroptera: Chrysopidae), the two-spotted lady beetle, Adalia bipunctata L. (Coleoptera: Coccinellidae), and the gall midge Aphidoletes aphidimyza (Rondani) (Diptera: Cecidomyiidae). Third instars of all 3 predators readily preyed upon the shallot aphid in Petri dish set-ups with significant differences in daily

Lachrymatory factor synthase (LFS) catalyzes the formation of lachrymatory factor, one of the most distinctive traits of bulb onion (Allium cepa L.). Therefore, we used LFS as a model for a functional gene in a huge genome, and we examined the chromosomal organization of LFS in A. cepa by multiple approaches. The first-level analysis completed the chromosomal assignment of LFS gene to chromosome 5 of A. cepa via the use of a complete set of A. fistulosum–shallot (A. cepa L. Aggregatum group) monosomic addition lines. Subsequent use of an F2 mapping population from the interspecific cross A. cepa × A. roylei confirmed the assignment of an LFS locus to this chromosome. Sequence comparison of two BAC clones bearing LFS genes, LFS amplicons from diverse germplasm, and expressed sequences from a doubled haploid line revealed variation consistent with duplicated LFS genes. Furthermore, the BAC-FISH study using the two BAC clones as a probe showed that LFS genes are localized in the proximal region of the long arm of the chromosome. These results suggested that LFS in A. cepa is transcribed from at least two loci and that they are localized on chromosome 5. PMID:22690373

The Allium genus includes garlic, onions, shallots, leeks, and chives. These vegetables are popular in cuisines worldwide and are valued for their potential medicinal properties. Epidemiological studies, while limited in their abilities to assess Allium consumption, indicate some associations of Allium vegetable consumption with decreased risk of cancer, particularly cancers of the gastrointestinal tract. Limited intervention studies have been conducted to support these associations. The majority of supportive evidence on Allium vegetables cancer preventive effects comes from mechanistic studies. These studies highlight potential mechanisms of individual sulfur-containing compounds and of various preparations and extracts of these vegetables, including decreased bioactivation of carcinogens, antimicrobial activities, and redox modification. Allium vegetables and their components have effects at each stage of carcinogenesis and affect many biological processes that modify cancer risk. This review discusses the cancer preventive effects of Allium vegetables, particularly garlic and onions, and their bioactive sulfur compounds and highlights research gaps. PMID:25586902

2010-04-01

This study investigated the protective effect of Allium neapolitanum Cyr., a spontaneous species of the Italian flora, compared with garlic (Allium sativum L.) on liver injury induced by ethanol in rats. Male albino Wistar rats were orally treated with fresh Allium homogenates (leaves or bulbs, 250 mg/kg) daily for 5 days, whereas controls received vehicle only. At the end of the experimental 5-day period, the animals received an acute ethanol dose (6 mL/kg, i.p.) 2 hours before the last Allium administration and were sacrificed 6 hours after ethanol administration. The activities of catalase (CAT), superoxide dismutase (SOD), and glutathione reductase (GR) and the levels of malondialdehyde (MDA), ascorbic acid (AA), and reduced (GSH) and oxidized glutathione in liver tissue were determined. Administration of both Allium species for 5 days (leaves or bulbs) led to no statistical variation of nonenzymatic parameters versus the control group; otherwise Allium treatment caused an increase of GSH and AA levels compared with the ethanol group and a diminution of MDA levels, showing in addition that A. neapolitanum bulb had the best protective effect. Regarding to enzymatic parameters, GR and CAT activities were enhanced significantly compared with the ethanol group, whereas SOD activity showed a trend different from other parameters estimated. However, the treatment with both Allium species followed by acute ethanol administration reestablished the nonenzymatic parameters similar to control values and enhanced the activities of the enzymes measured. These results suggest that fresh Allium homogenates (leaves or bulbs) possess antioxidant properties and provide protection against ethanol-induced liver injury.

Garlic, Allium sativum, is broadly used around the world for its numerous culinary and medicinal uses. Wild garlic, Allium vineale, has been used as a substitute for garlic, both in food as well as in herbal medicine. The present study investigated the chemical compositions of A. sativum and A. vineale essential oils. The essential oils from the bulbs of A. sativum, cultivated in Spain, were obtained by three different methods: laboratory hydrodistillation, industrial hydrodistillation, and industrial steam distillation. The essential oils of wild-growing A. vineale from north Alabama were obtained by hydrodistillation. The resulting essential oils were analyzed by gas chromatography-flame ionization detection (GC-FID) and gas chromatography-mass spectrometry (GC-MS). Both A. sativum and A. vineale oils were dominated by allyl polysulfides. There were minor quantitative differences between the A. sativum oils owing to the distillation methods employed, as well as differences from previously reported garlic oils from other geographical locations. Allium vineale oil showed a qualitative similarity to Allium ursinum essential oil. The compositions of garlic and wild garlic are consistent with their use as flavoring agents in foods as well as their uses as herbal medicines. However, quantitative differences are likely to affect the flavor and bioactivity profiles of these Allium species. PMID:28783070

The aims of this study were to prepare a Persian version of the temporal resolution test using the method of Phillips et al (1994) and Stuart and Phillips (1996), and to compare the word-recognition performance in the presence of continuous and interrupted noise as well as the temporal resolution abilities between monolingual (ML) Persian and bilingual (BL) Turkish-Persian young adults. Word-recognition scores (WRSs) were obtained in quiet and in the presence of background competing continuous and interrupted noise at signal-to-noise ratios (SNRs) of -20, -10, 0, and 10 dB. Two groups of 33 ML Persian and 36 BL Turkish-Persian volunteers participated. WRSs significantly differed between ML and BL subjects at four sensation levels in the presence of continuous and interrupted noise. However, the difference in the release from masking between ML and BL subjects was not significant at the studied SNRs. BL Turkish-Persian listeners seem to show poorer performance when responding to Persian words in continuous and interrupted noise. However, bilingualism may not affect auditory temporal resolution ability.

Research on emotional speech often requires valid stimuli for assessing perceived emotion through prosody and lexical content. To date, no comprehensive emotional speech database for Persian is officially available. The present article reports the process of designing, compiling, and evaluating a comprehensive emotional speech database for colloquial Persian. The database contains a set of 90 validated novel Persian sentences classified in five basic emotional categories (anger, disgust, fear, happiness, and sadness), as well as a neutral category. These sentences were validated in two experiments by a group of 1,126 native Persian speakers. The sentences were articulated by two native Persian speakers (one male, one female) in three conditions: (1) congruent (emotional lexical content articulated in a congruent emotional voice), (2) incongruent (neutral sentences articulated in an emotional voice), and (3) baseline (all emotional and neutral sentences articulated in neutral voice). The speech materials comprise about 470 sentences. The validity of the database was evaluated by a group of 34 native speakers in a perception test. Utterances recognized better than five times chance performance (71.4 %) were regarded as valid portrayals of the target emotions. Acoustic analysis of the valid emotional utterances revealed differences in pitch, intensity, and duration, attributes that may help listeners to correctly classify the intended emotion. The database is designed to be used as a reliable material source (for both text and speech) in future cross-cultural or cross-linguistic studies of emotional speech, and it is available for academic research purposes free of charge.

Fly ash is a by-product of coal-fired electricity generation plants. Its utilization and disposal is of utmost importance. Using onion (Allium cepa) root tip system, the present study was carried out to evaluate the potential toxic and genotoxic effects of fly ash, collected from a thermal power plant in West Bengal, India. Prior to testing, the collected fly ash sample was mixed with sand in different proportions. Allium bulbs were allowed to germinate directly in fly ash and after five days the germinating roots were processed for the Allium test. Additionally, the Allium test was adapted for detecting DNA damage through comet assay. The results from the Allium test indicate that fly ash at 100% concentration inhibits root growth and mitotic indices; induces binucleated cells as a function of the proportion, but is not toxic at very low concentration. In the comet assay, a statistical increase for DNA strand breaks was found only at higher concentrations. The sample was analyzed by flame atomic absorption spectrometer for Zn, Pb, Cu, Ni, Cd and As, whose presence could partly be responsible for the toxicity of fly ash. The study concludes that the classical Allium test can give a more comprehensive data when done in combination with the comet assay, which is faster, simpler and independent of mitosis. Also when fly ash is used for other purposes in combination with soils, it should be judiciously used at very low concentrations in order to protect the ecosystem health from any potential adverse effects.

The Persian cat is mainly characterized by an extremely brachycephalic face as part of the standard body conformation. Despite the popularity, world-wide distribution, and economic importance of the Persian cat as a fancy breed, little is known about the genetics of their hallmark morphology, brachycephaly. Over 800 cats from different breeds including Persian, non-Persian breeds (Abyssinian, Cornish Rex, Bengal, La Perm, Norwegian Forest, Maine Coon, Manx, Oriental, and Siamese), and Persian-derived breeds (British Shorthair, Scottish Fold, Selkirk Rex) were genotyped with the Illumina 63 K feline DNA array. The experimental strategy was composed of three main steps: (i) the Persian dataset was screened for runs of homozygosity to find and select highly homozygous regions; (ii) selected Persian homozygous regions were evaluated for the difference of homozygosity between Persians and those considered non-Persian breeds, and, (iii) the Persian homozygous regions most divergent from the non-Persian breeds were investigated by haplotype analysis in the Persian-derived breeds. Four regions with high homozygosity (H > 0.7) were detected, each with an average length of 1 Mb. Three regions can be considered unique to the Persian breed, with a less conservative haplotype pattern in the Persian-derived breeds. Moreover, two genes, CHL1 and CNTN6 known to determine face shape modification in humans, reside in one of the identified regions and therefore are positional candidates for the brachycephalic face in Persians. In total, the homozygous regions contained several neuronal genes that could be involved in the Persian cat behavior and can provide new insights into cat domestication.

Assessment of arsenic toxicity using Allium/Vicia root tip micronucleus assays.

PubMed

Wu, Lihua; Yi, Huilan; Yi, Min

2010-04-15

Arsenic is ubiquitous in the environment and is a potential human carcinogen. Its carcinogenicity has been demonstrated in several models. In this study, broad bean (Vicia faba L.) and common onion (Allium cepa L.), two plant species which are commonly used for detecting the genotoxic effects of environmental pollutants, were used to measure possible genotoxic effect of arsenite (0.3-30 mg/l). Present results showed that arsenite (As(III)) induced micronuclei (MN) formation in both Allium and Vicia root tips. MN frequency significantly increased in Vicia root cells exposed to 0.3-10 mg/l arsenite and in Allium root cells exposed to 1-30 mg/l arsenite, which indicated that Vicia root tip cells are more sensitive to arsenite than Allium. Mitotic index (MI) decreased in a concentration-dependent manner and showed significant differences in Vicia/Allium roots among treatments and the control, after exposure to 1-30 mg/l arsenite for at least 4 h. In the present study, MN frequency was positively associated with lipid peroxidation, which indicated that arsenite exposure can induce oxidative stress, cytotoxicity and genotoxicity in plant cells. The results also suggested that Vicia/Allium root micronucleus (MN) assays are simple, efficient and reproducible methods for the genotoxicity monitoring of arsenic water contamination. 2009 Elsevier B.V.

We evaluated organosulphur compounds in Allium vegetables, including garlic, elephant garlic and onion, using high-performance liquid chromatography. Among organosulphur compounds, elephant garlic had considerable γ-glutamyl peptides, and garlic had the highest alliin content. Onion had low level of organosulphur compounds than did elephant garlic and garlic. In addition, antioxidant capacities were evaluated by oxygen radical absorbance capacity (ORAC) values and 2,2-diphenyl-1-picrylhydrazyl (DPPH) and 2,2'-azinobis(3-ethylbenzothiazoline-6-sulphonic acid) (ABTS) radical scavenging assay. The results showed that garlic had the highest antioxidant capacity, followed by elephant garlic and onion. Furthermore, a positive correlation was observed between antioxidant activities and organosulphur compounds (R > 0.77). Therefore, our results indicate that there was a close relationship between antioxidant capacity and organosulphur compounds in Allium vegetables.

Allium vegetables, such as garlic and onion, have understudied genomes and limited molecular resources, hindering advances in genetic research and breeding of these species. In this study, we characterized and compared the simple sequence repeats (SSR) landscape in the transcriptomes of garlic and related Allium (A. cepa, A. fistulosum, and A. tuberosum) and non-Allium monocot species. In addition, 110 SSR markers were developed from garlic ESTs, and they were characterized-along with 112 previously developed SSRs-at various levels, including transferability across Alliaceae species, and their usefulness for genetic diversity analysis. Among the Allium species analyzed, garlic ESTs had the highest overall SSR density, the lowest frequency of trinucleotides, and the highest of di- and tetranucleotides. When compared to more distantly related monocots, outside the Asparagales order, it was evident that ESTs of Allium species shared major commonalities with regards to SSR density, frequency distribution, sequence motifs, and GC content. A significant fraction of the SSR markers were successfully transferred across Allium species, including crops for which no SSR markers have been developed yet, such as leek, shallot, chives, and elephant garlic. Diversity analysis of garlic cultivars with selected SSRs revealed 36 alleles, with 2-5 alleles/locus, and PIC = 0.38. Cluster analysis grouped the accessions according to their flowering behavior, botanical variety, and ecophysiological characteristics. Results from this study contribute to the characterization of Allium transcriptomes. The new SSR markers developed, along with the data from the polymorphism and transferability analyses, will aid in assisting genetic research and breeding in garlic and other Allium.

Preliminary sensory evaluation of edible flowers from wild Allium species.

2013-11-01

The use of edible flowers as an aesthetic and flavour component of specific dishes is gaining popularity, and their production is becoming an interesting niche market activity for growers. Allium is an important genus of flowering plants, also including traditional wild food species. The combination of tradition with the new uses of flowers is appealing, requiring, however, explorative acceptance assays for its exploitation. The flowers of the native Mediterranean species Allium neapolitanum, A. roseum and A. triquetrum were subject to hedonic visual, smell and flavour evaluation. Panellists also indicated specific flavour notes and their opinion about the more suitable uses. All the species were positively rated. A. roseum was preferred for all respects; A. triquetrum obtained the lowest visual rating, whereas A. neapolitanum had the lowest flavour rating. A spicy note was the main determinant of high flavour ratings. Dishes retaining the visual appearance of flowers were indicated as more suitable to combine with Allium flowers. This is the first attempt at sensory evaluation of Allium flowers. Nutritional and health promotion properties and toxicity risks do not represent major issues for these products, because of potentially low consumption levels. The main constraint for a wider use of Allium flowers is represented by the absence of a consolidated consumption habit and regular supply. © 2013 Society of Chemical Industry.

Extracts of some spices have been reported to play a contributory role in enhancing immune function. We evaluated and compared the effect(s) of single and combined oral administration of fresh aqueous onion (Allium cepa) and garlic (Allium sativum) extracts at different concentrations on some immunological determinants in rats. CD₄ cells of the rats were estimated using Partec flow cytometric technique, while total and differential white blood cell (WBC) counts were estimated using the Sysmsex® automated haematology analyzing technique. Our findings revealed that, CD4 and total WBC counts were significantly increased (P≤0.05) in a dose-dependent manner in both onion (250mg/Kg/d: 349±11cell/ul and 2.75±0.15X10³cell/l; 500mg/Kg/d: 389±10cells/µl and 3.05±0.05 X10³cell/l; 750mg/Kg/d: 600±11cell/µl and 3.25±0.05X10³cells/l) and garlic (250mg/Kg/d: 410±10cell/ul and 2.85±0.15X10³cell/l; 500mg/Kg/d: 494±32cells/µl and 3.30±0.10 X10³cell/l; 750mg/Kg/d: 684±11cell/µl and 3.55±0.05X10³cells/l) treated rats when compared to the zero control (200±11cells/µl and 1.55±0.05X10³cells/l, respectively). Extract of garlic at 750mg/Kg/d had significantly increased the CD4 cells and total white cell count when compared to other concentrations (P≤0.05). However, no significant effect was observed on these parameters when extracts were combined (250mg/Kg/d: 252±21cell/µl and 1.80±0.10X10³cells/l; 500mg/Kg/d: 315±21cells/ul and 2.10±0.10X10³cells/l; 750mg/Kg/d: 368±10cells/µl and 2.35±0.05X10³cells/l, respectively), the differential WBC count showed a significant increase in the proportion of cell types (lymphocytes, neutophils and monocytes) (P≤0.05). The results from this study revealed the immune boosting capabilities of Allium cepa and Allium sativum, but underscored their synergistic activities.

Garlic (Allium sativum) has a well-established reputation as a protective agent against cardiovascular disease, while nearly nothing is known about its cousin Allium ursinum. The aim of this study was to evaluate the antiaggregatory mechanism of garlic and to compare the effects of A. ursinum and A. sativum. In a prospective study, extracts were prepared from A. sativum powder made from fresh A. sativum bulbs and fresh A. ursinum leaves by maceration. The extracts were characterized by thin layer chromatography. Their in vitro effects on human platelet aggregation were examined by light transmission aggregometry after induction by adenosine diphosphate (ADP), collagen, A23187, epinephrine and arachidonic acid (ARA) in platelets from healthy volunteers. A. ursinum and A. sativum exert similar antiaggregatory effects: they inhibit platelet aggregation induced via the ADP pathway and to a lesser extent aggregation induced by epinephrine, whereas ARA-, collagen- and A23187-induced aggregation was not affected. It became clear that the alcoholic extract of A. ursinum is the potent form, while the aqueous extract exerted an unspecific activity. The effects were strictly dose related. A. ursinum and A. sativum extracts exhibited similar potencies. Both A. ursinum and A. sativum exert antiaggregatory effects. Garlic extracts are acting by inhibition of the ADP pathway; their mechanisms of action are comparable to that of the clinically used drug clopidogrel. The pharmacologically active component of the extracts appears to be lipophilic rather than hydrophilic, but the precise chemical substance is still unknown. This is the first report on the antiplatelet activity of A. ursinum. Copyright 2009 S. Karger AG, Basel.

Mitigation of xerophilic storage fungi-associated aflatoxin threat in culinary oil will be a new technology advantage to food industries. Groundnut oil isolate Aspergillus flavus MTCC 10680 susceptibility to Allium species (A. sativum L., A. cepa L., and A. cepa var. aggregatum) extracts, composition, and in silico confirmation of extract's phytoconstituent aflatoxin synthesis inhibition were determined. The behavior of seasoning carrier medium groundnut oil in the presence of Allium was also determined. All the Allium species extracts exhibited concentration dependent in vitro inhibition on mycelial biomass, radial growth, and toxin elaboration. The gas chromatography-mass spectrometry revealed the presence of 28, 16, and 9 compounds in the extracts of A. sativum, A. cepa, A. cepa var. aggregatum, respectively. The Allium phytocostituents-like hexadecanoic acid, 5-Octanoyl-2,4,6(1H,3H,5H)-pyrimidinetrione, Guanosine, and so on, showed higher binding energy with aflatoxin synthesis key enzyme ver1. Allium seasoning increased the typical nutty odor of the groundnut oil with sweet aroma note as well as intensification of pale yellow color. Allium seasoning exhibited the highest aflatoxin detoxification and aroma development without any nutritional loss. Culinary oil Allium seasoning has anti-aflatoxin and food additive potential for use in food industries. © 2014 Institute of Food Technologists®

In Iran, a large group of patients are elderly people and they intend to have natural remedies as treatment. These remedies are rooted in historical of Persian and humoral medicine with a backbone of more than 1000 years. The current study was conducted to draw together medieval pharmacological information related to geriatric medicine from some of the most often manuscripts of traditional Persian medicine. Moreover, we investigated the efficacy of medicinal plants through a search of the PubMed, Scopus and Google Scholar databases. In the medieval Persian documents, digestible and a small amount of food such as chicken broth, honey, fig and plum at frequent intervals as well as body massage and morning unctioning are highly recommended. In the field of pharmacotherapy, 35 herbs related to 25 families were identified. Plants were classified as tonic, anti-aging, appetizer, memory and mood enhancer, topical analgesic and laxative as well as health improvement agents. Other than historical elucidation, this paper presents medical and pharmacological approaches that medieval Persian practitioners applied to deal with geriatric complications. PMID:24381461

The meristematic mitotic cells of plant roots are appropriate and efficient cytogenetic materials for the detection of clastogenicity of environmental pollutants, especially for in situ monitoring of water contaminants. Among several cytological endpoints in these fast dividing cells, such as chromosome/chromatid aberrations, sister-chromatid exchanges and micronuclei, the most effective and simplest indicator of cytological damage is micronucleus formation. Although the Allium cepa and Vicia faba root meristem micronucleus assays (Allium/Vicia root MCN) have been used in clastogenicity studies about 12 times by various authors in the last 25 years, there is no report on the comparison of the efficiency of these two plant systems and in different cell populations (meristem and F1) of the root tip as well as under adequate recovery duration. In order to maximize the efficiency of these bioassays, the current study was designed to compare the Allium and the Vicia root MCN assays on the basis of chromosome length, peak sensitivity of the mitotic cells, and the regions of the root tip where the MCN are formed. The total length of the 2n complement of Allium chromosomes is 14.4 microns and the total length of the 2n complement of Vicia is 9.32 microns. The peak sensitivity determined by serial fixation at 12-h intervals after 100 R of X-irradiation is 44 h. The slope of the X-ray dose-response curve of Allium roots derived from the meristematic regions was lower than that derived from cells in the F1 region. Higher efficiency was also demonstrated when the MCN frequencies were scored from the F1 cells in both Allium and Vicia treated with formaldehyde (FA), mitomycin C (MMC), and maleic hydrazide (MH). The results indicated that scoring of MCN frequencies from the F1 cell region of the root tip was more efficient than scoring from the meristematic region. The X-ray linear regression dose-response curves were established in both Allium and Vicia cell systems and the

The effects of both garlic (Allium sativum) and onion (Allium cepa) on some biochemical parameters in Schistosoma mansoni infected mice individually and mixed either with or without the currently used drug, praziquantel (PZQ) were investigated. These involved some immunological parameters, namely IgM, IgG, interleukins 2 and 6 (IL-2 and 6) and tumor necrosis factor (TNF-α), some antioxidant enzymes [catalase, superoxide dismutase (SOD) and glutathione peroxidase (GPX)]. In addition, parasitological and histopathological investigations were performed. No changes were observed in the normal control mice treated with dry extract of onion or garlic, individually or mixed, with or without PZQ, compared to the normal healthy control group. Infection with S. mansoni showed an increase in IgG, IgM, IL-2, IL-6, TNF-α and catalase enzyme, accompanied with a decrease in GPX and SOD antioxidant enzyme activities. Remarkable amelioration was noticed in the levels of all the measured parameters in S. mansoni infected mice after administration of the studied extracts. Moreover a significant reduction in worm burden, hepatic and intestinal eggs and oogram count was noticed which was reflected in normalization of liver architecture.

Al Eskan disease: Persian Gulf syndrome.

Korényi-Both, A L; Korényi-Both, A L; Juncer, D J

1997-01-01

This article examines the potential relationship between Al Eskan disease and the Persian Gulf syndrome. Al Eskan disease, reported in Military Medicine in 1992, is a novel and previously unreported condition triggered by the exceptionally fine sand dust of the Central and Eastern Saudi Arabian peninsula. We repeat our study of the pathogenesis of Al Eskan disease to include the ultrastructural and microanalytical study of the sand, aerobiological studies of the Kingdom of Saudi Arabia, and the etiology, symptoms, and prevalence of the disease. We conclude that immunodepression resulting from the continued presence of sand particles less than 1 micron in diameter in the lungs and bodies of Persian Gulf veterans explains not only the symptoms of the hyperegic lung condition of phase I and the symptoms of phase II of Al Eskan disease, but also provides an important clue to a common factor in most cases of Persian Gulf illnesses. We include a discussion of most of the commonly suspected agents in the Persian Gulf syndrome. In this case, we conclude that each of these factors, such as oil well fires, old-world diseases, or depleted uranium, are probably adjuvant or contributing causes. The only common exposure that would lead to recognition of the Persian Gulf syndrome as a single medical condition, rather than a catch-all phrase for unrelated conditions, appears to be exposure to the ubiquitous, fine sand of the area, and a resulting immunosuppression that is aggravated by opportunistic infections and other nonmicrobial ailments.

Objectives. Functional components in alliums have long been maintained to play a key role in modifying the major risk factors for chronic disease. To obtain a better understanding of alliums for chronic disease prevention, we conducted a systematic review for risk factors and prevention strategies for chronic disease of functional components in alliums, based on a comprehensive English literature search that was conducted using various electronic search databases, especially the PubMed, ISI Web of Science, and CNKI for the period 2007–2016. Allium genus especially garlic, onion, and Chinese chive is rich in organosulfur compounds, quercetin, flavonoids, saponins, and others, which have anticancer, preventive cardiovascular and heart diseases, anti-inflammation, antiobesity, antidiabetes, antioxidants, antimicrobial activity, neuroprotective and immunological effects, and so on. These results support Allium genus; garlic and onion especially may be the promising dietotherapeutic vegetables and organopolysulfides as well as quercetin mechanism in the treatment of chronic diseases. This review may be used as scientific basis for the development of functional food, nutraceuticals, and alternative drugs to improve the chronic diseases. PMID:28261311

The color of urine is an important factor in urine examination, which can help physicians differentiate various diseases. Today, it is known that certain dyes, drug intoxications, and diseases can induce green urine discoloration. In the view of traditional Persian medicine, which is based on humoral medicine, green urine discoloration is generally referred to the dominance of coldness in the body. In fact, it is considered to be a result of a special kind of humoral imbalance and fluid depletion or retention in the human body. Persian scholars believed that green urine could be an indicator of intoxication or a predictor of an imminent spasm or convulsion in pediatric patients. Further investigations could result in finding new diagnostic scales of urine color based on the teachings of traditional Persian medicine. PMID:27103627

Word-level prominence in Persian: An Experimental Study.

PubMed

Sadeghi, Vahid

2017-12-01

Previous literature on the phonetics of stress in Persian has reported that fundamental frequency is the only reliable acoustic correlate of stress, and that stressed and unstressed syllables are not differentiated from each other in the absence of accentuation. In this study, the effects of lexical stress on duration, overall intensity and spectral tilt were examined in Persian both in the accented and unaccented conditions. Results showed that syllable duration is consistently affected by stress in Persian in both the accented and unaccented conditions across all vowel types. Unlike duration, the results for overall intensity and spectral tilt were significant only in the accented condition, suggesting that measures of intensity are not a correlate of stress in Persian but they are mainly caused by the presence of a pitch movement. The findings are phonologically interpreted as suggesting that word-level prominence in Persian is typologically similar to 'stress accent' languages, in which multiple phonetic cues are used to signal the prominence contrast in the accented condition, and stressed and unstressed syllables are different from each other even when the word is not pitch-accented.

To cross-culturally adapt the Achilles tendon Total Rupture Score (ATRS) to Persian language and to preliminary evaluate the reliability and validity of a Persian ATRS. A cross-sectional and prospective cohort study was conducted to translate and cross-culturally adapt the ATRS to Persian language (ATRS-Persian) following steps described in guidelines. Thirty patients with total Achilles tendon rupture and 30 healthy subjects participated in this study. Psychometric properties of floor/ceiling effects (responsiveness), internal consistency reliability, test-retest reliability, standard error of measurement (SEM), smallest detectable change (SDC), construct validity, and discriminant validity were tested. Factor analysis was performed to determine the ATRS-Persian structure. There were no floor or ceiling effects that indicate the content and responsiveness of ATRS-Persian. Internal consistency was high (Cronbach's α 0.95). Item-total correlations exceeded acceptable standard of 0.3 for the all items (0.58-0.95). The test-retest reliability was excellent [(ICC)agreement 0.98]. SEM and SDC were 3.57 and 9.9, respectively. Construct validity was supported by a significant correlation between the ATRS-Persian total score and the Persian Foot and Ankle Outcome Score (PFAOS) total score and PFAOS subscales (r = 0.55-0.83). The ATRS-Persian significantly discriminated between patients and healthy subjects. Explanatory factor analysis revealed 1 component. The ATRS was cross-culturally adapted to Persian and demonstrated to be a reliable and valid instrument to measure functional outcomes in Persian patients with Achilles tendon rupture. II.

Extraction and antioxidant activity of polysaccharide from Allium sativum were investigated. The crude polysaccharide was obtained by the hot-water extraction method. The molecular weight of polysaccharide deproteinized with CaCl 2 was 7.35×10 3 . It indicated that polysaccharide from Allium sativum consisted of three monosaccharides, namely fructose, glucose, and galactose by HPLC. The polysaccharide had the β-glycosidic bond. Moreover, it was proved that the polysaccharide had the potential scavenging ability to superoxide anions and hydroxyl radicals. So, it should be a potential antioxidant.

Lepimectin, as an emulsifiable concentrate, was sprayed on shallots at the recommended dose rate (10 mL/20 L) to determine its residue levels, dissipation pattern, pre-harvest residue limits (PHRLs), and health risk. Samples were randomly collected over 10 days, extracted with acetonitrile, purified using an amino solid-phase extraction (NH 2 -SPE) cartridge and analyzed using a high-performance liquid chromatography-photodiode array detection method. Field-incurred samples were confirmed using ultra-performance liquid chromatography-tandem mass spectrometry. The linearity was excellent, with a determination coefficient (R 2 ) of ≥0.9991. The recoveries at two spiking levels (0.2 and 1.0 mg/kg) ranged from 84.49 to 87.64% with relative standard deviations of ≤7.04%. The developed method was applied to field samples grown in separate greenhouses, one located in Naju and one in Muan, in the Republic of Korea. The dissipation pattern was described by first-order kinetics with half-lives of 1.9 (Naju) and 1.7 days (Muan). The PHRL curves indicated that, if the lepimectin residues are <0.18 (Naju) and <0.13 mg/kg (Muan) 5 days before harvest, the residue levels will be lower than the maximum residue limit (0.05 mg/kg) upon harvesting. The risk assessment data indicated that lepimectin is safe for use in the cultivation of shallots, with no risk of detrimental effects to the consumer. Copyright © 2016 John Wiley & Sons, Ltd.

Persian language is the official language of Iran, Tajikistan and Afghanistan. Local online users often represent their opinions and experiences on the web with written Persian. Although the information in those reviews is valuable to potential consumers and sellers, the huge amount of web reviews make it difficult to give an unbiased evaluation to a product. In this paper, standard machine learning techniques SVM and naive Bayes are incorporated into the domain of online Persian Movie reviews to automatically classify user reviews as positive or negative and performance of these two classifiers is compared with each other in this language. The effects of feature presentations on classification performance are discussed. We find that accuracy is influenced by interaction between the classification models and the feature options. The SVM classifier achieves as well as or better accuracy than naive Bayes in Persian movie. Unigrams are proved better features than bigrams and trigrams in capturing Persian sentiment orientation.

There is growing interest in the use of plants for the treatment and prevention of cancer. Medicinal plants are currently being evaluated as source of promising anticancer agents. In this paper, we have investigated the anticancer potential of plant Allium wallichii, a plant native to Nepal and growing at elevations of 2300-4800 m. This is the first study of its kind for the plant mentioned. The dried plant was extracted in aqueous ethanol. Phytochemical screening, anti-microbial assay, anti-oxidant assay, cytotoxicity assay and the flow-cytometric analysis were done for analyzing different phytochemicals present, anti-microbial activity, anti-oxidant activity and anti-cancer properties of Allium wallichii. We observed the presence of steroids, terpenoids, flavonoids, reducing sugars and glycosides in the plant extract and the plant showed moderate anti-microbial and anti-oxidant activity. The IC 50 values of Allium wallichii in different cancer cell lines are 69.69 μg/ml for Prostate cancer (PC3) cell line, 55.29 μg/ml for Breast Cancer (MCF-7) cell line and 46.51 μg/ml for cervical cancer (HeLa) cell line as compared to Doxorubicin (0.85 μg/ml). The cell viability assay using FACS showed that the IC 50 value of Allium wallichii for Burkitt's lymphoma (B-Lymphoma) cell line was 3.817 ± 1.99 mg/ml. Allium wallichii can be an important candidate to be used as an anticancer agent. Separation of pure compounds with bioassay guided extraction, spectrometric analysis and subsequent cytotoxicity assay of the pure bioactive compounds from Allium wallichii is highly recommended as the crude extract itself showed promising cytotoxicity.

Translation, cross-culturally adaptation and validation of a Persian version of COOP/WONCA charts in Persian-speaking Iranians with multiple sclerosis (MS). The Persian version of COOP/WONCA charts was developed after a standard forward translation, synthesis and backward translation. A total of 197 subjects with MS participated in this study. They were asked to complete the COOP/WONCA charts and Short-Form 36 Health Survey (SF-36). The COOP/WONCA charts were re-administered to 50 patients, 4 weeks after the first session. Expanded Disability Status Scale (EDSS) was also scored for each subject by the referring physician. Construct validity was assessed by testing linear relationship between corresponding domains of the COOP/WONCA charts, the SF-36 and the EDSS. Test-retest reliability was examined using interclass correlation coefficient (ICC), standard error of measurement (SEM) and minimal detectable change (MDC) values. Related domains of COOP/WONCA charts and SF-36 demonstrated strong linear relationships with Spearman's coefficients ranging from -0.51 to -0.75 (p< 0.05). Physical fitness and daily activity charts also demonstrated strong relationships with the EDSS by Spearman's coefficients of 0.65 and 0.50, respectively (p< 0.05). The ICC values for most of COOP/WONCA charts domains were acceptable (>0.70) except for feelings and quality-of-life domains that were 0.50 and 0.51, respectively. The Persian version of the COOP/WONCA charts was shown to be psychometrically appropriate to evaluate the functional level and quality of life in Persian-speaking Iranians with MS. Implications for rehabilitation COOP/WONCA charts are now available in Persian and demonstrate good psychometric properties. COOP/WONCA charts demonstrate excellent reliability and construct validity in a Persian-speaking Iranian population with MS. Minimal detectable change in COOP/WONCA is now available in MS to guide within and between group analyses. Knowledge on a wide variety of

In vitro effectiveness of garlic (Allium sativum) extract on scolices of hydatid cyst.

Surgery is still the main treatment for hydatid disease. Recurrence of the infection is one of the end points of surgery in treating the hydatid cyst which results from the dissemination of protoscolices-rich fluid. Installation of a scolicidal agent into the cyst is the most commonly employed measure to prevent recurrence. Many scolicidal agents have been used for inactivation of the cyst's content, but most of them are not safe due to their undesired side effects. In the present study, the scolicidal effect of methanolic extract of Allium sativum is investigated. Protoscolices were aseptically collected from sheep livers containing hydatid cysts. Two concentrations (25 and 50 mg ml(-1)) of garlic extract were used for 10, 20, 30, 40, 50, and 60 min. Viability of protoscolices was confirmed by 0.1% eosin staining. Allium sativum extract at the concentration of 25 mg ml(-1) killed 87.9, 95.6, 96.8, 98.7, 99.6, and 100% of protoscolices following 10, 20, 30, 40, 50, and 60 min of application, respectively. Moreover, the scolicidal activity of Allium sativum extract at the concentration of 50 mg ml(-1) was 100% after 10 min of application. Methanolic extract of Allium sativum had a high scolicidal activity in vitro and thus might be used as a scolicidal agent in the surgical treatment of the hydatid cyst. However, further investigation on the in vivo efficacy of Allium sativum extract and its possible side effects is proposed.

Although the incidence of stomach cancer has been declining, it remains the second leading cause of cancer death worldwide. Potential protective effects of allium vegetables against cancer have been reported by a few epidemiologic studies in Chinese populations, but the sample sizes of these studies were relatively small. We examined the associations between allium vegetable consumption and stomach cancer in a large population-based case-control study in Shanghai (750 cases and 750 age- and gender-matched controls) and Qingdao (128 cases and 128 age- and gender-matched controls). Epidemiological data were collected by a standard questionnaire, and odds ratios (ORs) and 95% confidence intervals (CIs) were estimated using conditional logistic regression in SAS. After adjusting for matching variables, education, body mass index, pack-years of smoking, alcohol drinking, salt intake, and fruit and vegetable intake, inverse relationships with dose response pattern were observed between frequency of onion intake and stomach cancer in Qingdao (P for trend=0.02) and Shanghai (P for trend=0.04) populations. In Shanghai, negative dose-response relationships were observed between monthly intake of onions (P=0.03), monthly intake of garlic stalks (P=0.04) and distal cancer (but not with cardia cancer). Negative association was also noted between intake of garlic stalks (often vs. never) and risk of stomach cancer in Qingdao (OR=0.30; 95% CI: 0.12–0.77). Our results confirm the protective effect of allium vegetables (especially garlic and onions) against stomach cancer. PMID:16236005

The schistosomicidal properties of garlic (Allium sativum) and onion (Allium cepa) powder were tested in vitro against Schistosoma mansoni miracidia, schistosomula, cercaria and adult worms. Results indicate their strong biocidal effects against all stages of the parasite and also show scavenging inhibitory effect on 2,2-diphenyl-1-picrylhydrazyl (DPPH) and nitric oxide (NO). In the present work, the in vivo effects of A. sativum and A. cepa on lipid peroxide and some antioxidant enzymes; thioredoxin reductase (TrxR), sorbitol dehydrogenase (SDH), superoxide dismutase (SOD), catalase (CAT) and glutathione reductase (GR) (as they have a crucial role in host protection against invading parasite) were also studied. The data demonstrate that, there was a significant inhibition in SOD, CAT, GR, TrxR and SDH in infected liver while, significant elevation was detected in lipid peroxide as compared to the normal control. The current resultS clearly revealed that, the used both edible plants enhance the host antioxidant system indicated by lowering in lipid peroxide and stimulation of SOD, CAT, GR, TrxR and SDH enzyme levels. Enhancement of such enzymes using A. sativum and A. cepa could in turn render the parasite vulnerable to damage by the host and may play a role in the antischistosomal potency of the used food ingredients.

The present investigation was directed to study the possible protective activity of quercetin—a natural antioxidant against dimethoate-induced cyto- and genotoxicity in meristematic cells of Allium sativum. So far there is no report on the biological properties of quercetin in plant test systems. Chromosome breaks, multipolar anaphase, stick chromosome, and mitotic activity were undertaken in the current study as markers of cyto- and genotoxicity. Untreated control, quercetin controls (@ 5, 10 and 20 μg/mL for 3 h), and dimethoate exposed groups (@ 100 and 200 μg/mL for 3 h) were maintained. For protection against cytogenotoxicity, the root tip cells treated with dimethoate at 100 and 200 μg/mL for 3 h and quercetin treatment at 5, 10, and 20 μg/mL for 16 h, prior to dimethoate treatment, were undertaken. Quercetin was found to be neither cytotoxic nor genotoxic in Allium sativum control at these doses. A significant increase (P < 0.05) in chromosomal aberrations was noted in dimethoate treated Allium. Pretreatment of Allium sativum with quercetin significantly (P < 0.05) reduced dimethoate-induced genotoxicity and cytotoxicity in meristematic cells, and these effects were dose dependent. In conclusion, quercetin has a protective role in the abatement of dimethoate-induced cyto- and genotoxicity in the meristematic cells of Allium sativum that resides, at least in part, on its antioxidant effects.

This study aimed to translate the original English version of the Geriatric Oral Health Assessment Index (GOHAI) into a Persian version and to assess the preliminary psychometric properties of the translated index among a sample of Persian elders. Twelve items included in GOHAI were first translated into Persian using a back-translation technique and then were compared with the original version. Four hundred and seventeen elderly subjects who were admitted to a day care centre answered GOHAI and an attached socio-demographic questionnaire. Internal consistency of the Persian version was measured by Cronbach's alpha. Test-retest reliability was assessed by intraclass correlation coefficient (ICC) and weighted kappa. Factor structure of GOHAI was evaluated by principal component factor analysis. Mean of GOHAI score was 45.71 (SD: 5.14; range: 27-51). The mean of GOHAI score was higher for the elders who rated their oral and general health as 'good'. The Cronbach's alpha for GOHAI score was 0.748, indicating a high degree of internal consistency and homogeneity between the GOHAI items. The test-retest correlation for the total GOHAI score using ICC was 0.763 (95% CI = 0.713-0.809). Factor analysis revealed a three-factor solution that bolstered the theoretical construction of the index. Significant differences in the GOHAI scores were found for income and current number of teeth. The Persian version of the GOHAI can be used reliably to identify oral health-related concerns of older Persian speakers, but further research is needed to confirm its cultural consonance in this population. © 2014 John Wiley & Sons A/S and The Gerodontology Association.

The most commonly used instrument for the research and treatment of excessive internet use is Young's Internet Addiction Test (IAT). While the IAT has been translated to several languages (including Persian) and has demonstrated good psychometric properties across several independent studies, there is still a room for alternative assessment instruments. This study reports a validation of the Persian version of the Problematic Internet Use Questionnaire (PIUQ). A sample (n = 296) from Kerman, Iran was administered the translated Persian version of the PIUQ as well as the Persian version of the University of California, Los Angeles (UCLA) Loneliness scale, Satisfaction With Life scale, and questions related to use of technology and the internet. Analyses using confirmatory and exploratory factor analyses demonstrated that the Persian version of the PIUQ had good internal reliability and concurrent validity (with loneliness and satisfaction with life), but they also had an alternative factor structure that did not support the original factor structure. The Persian version of the PIUQ produced adequate psychometric properties (internal reliability and concurrent validity), but care should be taken in the interpretation of the factor structure.

The objective of this study was to evaluate the histo pathology effects of two medicaments Allium sativum oil and formocresol on the remaining pulp tissue of the permanent teething children. A total of 18 premolars were included in this study. Two sound premolars were extracted and subjected to histological examination to show the normal pulp tissue. Pulpo tomy procedure was performed in the rest of the remaining 16 premolars; half of them using Allium sativum oil and the rest of the tested premolars were medicated using formocresol and all were sealed with suitable restoration. Then, premolars extracted at variable intervals (48 hours, 2 weeks, 1 month, 2 months), stained using hemotoxylin and eosin etain (H&E) and prepared for histopathology examination. Histological evaluation seemed far more promising for Allium sativum oil than formocresol. Histological evaluation revealed that teeth treated with Allium sativa oil showed infammatory changes that had been resolved in the end of the study. On the contrary, the severe chronic infammation of pulp tissue accompanied with formocresol eventually produced pulp necrosis with or without fibrosis. In addition, pulp calcification was evidenced in certain cases. Allium sativum oil is a biocompatible material that is compatible with vital human pulp tissue. It offers a good healing potential, leaving the remaining pulp tissue healthy and functioning.

The purpose of the study was to examine the psychometric properties of the Persian version of the Care Dependency Scale (CDS) in nursing homes. Instrument development. The English version of the CDS was translated into Persian. A convenience sample of 140 (100 older people without dementia and 40 patients with dementia) Persian-speaking people were selected from the nursing homes in Ahvaz, Iran. Cronbach's alpha, discriminant validity, and construct validity (exploratory factor analysis) were examined. Exploratory factor analysis indicated that the CDS has two factors, including psychosocial and somatic factors. Discriminant validity showed that the CDS can differentiate patients with dementia from the older adults without dementia. The results of the study showed that the Persian CDS is a reliable and valid scale when used in nursing homes. The Persian version of the CDS can help clinicians and nurses to assess patients' need and the degree of care dependency among older adults in Persian-speaking areas.

Leiomyoma is the most common benign tumor of the pelvic that is associated with reproductive problems such as infertility, frequent abortions, and undesirable prenatal outcomes. High prevalence of leiomyoma and its relation with important gynecological complications, especially during reproductive ages, on the one hand, and high medical expenses and significant complications of common treatments, on the other, made us search traditional Persian medicine texts for a similar disease. In traditional Persian medicine, a condition has been introduced similar to leiomyoma (Oram-e-rahem). In this article, by collecting materials from traditional medicine texts on leiomyoma, we aim to provide theories for further studies on this topic, as there is an obvious difference between traditional Persian medicine and modern medicine with regard to leiomyoma. When modern medicine has not found a suitable response to treatment, reviewing of traditional Persian medicine for finding better treatment strategies is wise. © The Author(s) 2015.

Wars and injuries have accompanied mankind throughout history. Physicians and surgeons from various civilizations made difficult attempts to manage wounds and injuries. Among various civilizations, the Persian Empires had great armies which were well equipped. One of the most important organizations in Persian troops was the military surgery. This study presents a brief biography of Hakim Mohammad (a military surgeon in Safavid era) and introduces his book, Dhakhira-yi-Kamilah. Safavid kings (1501-1736 CE) with unifying all of Persian regions and provinces reconstructed the Persian Empire. Great scholars and physicians were raised in this era. It seems that Persian physicians and surgeons were well trained in Safavid era and many of them were even employed by other countries like Ottoman Empire and India. Hakim Mohammad as a military surgeon was one of such physicians who served in Ottoman Empire for some time. He gathered his surgical experiences and others in the book of Dhakhira-yi-Kamilah. This book was written in Persian. He has mainly written about the management of wounds and practical techniques. Later, he came back to his homeland and dedicated his book to the king of Persia.

To validate the Persian version of the simple shoulder test in patients with shoulder joint problems. Following Beaton`s guideline, translation and back translation was conducted. We reached to a consensus on the Persian version of SST. To test the face validity in a pilot study, the Persian SST was administered to 20 individuals with shoulder joint conditions. We enrolled 148 consecutive patients with shoulder problem to fill the Persian SST, shoulder specific measure including Oxford shoulder score (OSS) and two general measures including DASH and SF-36. To measure the test-retest reliability, 42 patients were randomly asked to fill the Persian-SST for the second time after one week. Cronbach's alpha coefficient was used to demonstrate internal consistency over the 12 items of Persian-SST. ICC for the total questionnaire was 0.61 showing good and acceptable test-retest reliability. ICC for individual items ranged from 0.32 to 0.79. The total Cronbach's alpha was 0.84 showing good internal consistency over the 12 items of the Persian-SST. Validity testing showed strong correlation between SST and OSS and DASH. The correlation with OSS was positive while with DASH scores was negative. The correlation was also good to strong with all physical and most mental subscales of the SF-36. Correlation coefficient was higher with DASH and OSS in compare to SF-36. Persian version of SST found to be valid and reliable instrument for shoulder joint pain and function assessment in Iranian population.

Orthotics and Prosthetics User's Survey (OPUS) was developed to measure patient satisfaction in Prosthetic and Orthotic (P&O) field. To translate the satisfaction assessment module of OPUS (OPUS-SM) into Persian language (Persian OPUS-SM) and investigate its psychometric properties. For cross-cultural adaptation of the OPUS-SM, the guideline suggested by the World Health Organization was recruited. A sample of 116 Persian-speaking people who received P&O devices and services, participated in this study. During the first session, participants filled out the Persian OPUS-SM and the Visual Analog Scale (VAS) regarding their satisfaction from delivered devices and services. Drawing from the above sample of 116 participants, 41 participants retook the Persian OPUS-SM 5-7 days after their first time. The results of the first and second administration sessions were analyzed to assess internal consistency, test-retest reliability, item-subscale correlation, minimal detectable change, floor and ceiling effects, criterion validity, and dimensionality of the Persian OPUS-SM. The Cronbach's alphas of the Persian OPUS-SM were 0.71 and 0.89 for device and service satisfaction subscales, respectively. The intraclass correlation coefficients were 0.76 and 0.90 for device and service satisfaction subscales, respectively. The SEM and MDC for device satisfaction were 6.21 and ±17.21, respectively. The SEM and MDC for service satisfaction were 2.25 and ±6.22, respectively. There was a strong correlation between VAS and satisfaction subscales of the Persian OPUS-SM. Dimensionality assessment revealed that Persian OPUS-SM is a unidimensional measure. The adapted and translated Persian OPUS-SM is a reliable and validated measure. Copyright © 2016 Elsevier Inc.

Oxford Elbow Score (OES) is a patient-reported questionnaire used to assess outcomes after elbow surgery. The aim of this study was to validate and adapt the OES into Persian language. After forward-backward translation of the OES into Persian, a total number of 92 patients after elbow surgeries completed the Persian OES along with the Persian DASH and SF-36. To assess test-retest reliability, 31 randomly selected patients (34%) completed the Persian OES again after three days while abstaining from all forms of therapeutic regimens. Reliability of the Persian OES was assessed by measuring intraclass correlation coefficient (ICC) for test-retest reliability and Cronbach's alpha for internal consistency. Spearman's correlation coefficient was used to test the construct validity. Cronbach's alpha coefficient was 0.92 showing excellent reliability. Cronbach's alpha for function, pain, and social-psychological subscales was 0.95, 0.86, and 0.85, respectively. Intraclass correlation coefficient (ICC) was 0.85 for the overall questionnaire and 0.90, 0.76, and 0.75 for function, pain, and social-psychological subscales, respectively. Construct validity was confirmed as the Spearman correlation between OES and DASH was 0.80. Persian OES is a valid and reliable patient-reported outcome measure to assess postsurgical elbow status in Persian speaking population.

Due to the ease with which chromosomes can be observed, the Allium species, and onion in particular, have been familiar materials employed in cytogenetic experiments in biology. In this study, centromeric histone H3 (CENH3)-coding cDNAs were identified in four Allium species (onion, welsh onion, garlic and garlic chives) and cloned. Anti-CENH3 antibody was then raised against a deduced amino acid sequence of CENH3 of welsh onion. The antibody recognized all CENH3 orthologs of the Allium species tested. Immunostaining with the antibody enabled clear visualization of chromosome behavior during mitosis in the species. Furthermore, three-dimensional (3D) observation of mitotic cell division was achieved by subjecting root sections to immunohistochemical techniques. The 3D dynamics of the cells and position of cell-cycle marker proteins (CENH3 and α-tubulin) were clearly revealed by immunohistochemical staining with the antibodies. The immunohistochemical analysis made it possible to establish an overview of the location of dividing cells in the root tissues. This breakthrough in technique, in addition to the two centromeric DNA sequences isolated from welsh onion by chromatin immuno-precipitation using the antibody, should lead to a better understanding of plant cell division. A phylogenetic analysis of Allium CENH3s together with the previously reported plant CENH3s showed two separate clades for monocot species tested. One clade was made from CENH3s of the Allium species with those of Poaceae species, and the other from CENH3s of a holocentric species (Luzula nivea). These data may imply functional differences of CENH3s between holocentric and monocentric species. Centromeric localization of DNA sequences isolated from welsh onion by chromatin immuno-precipitation (ChIP) using the antibody was confirmed by fluorescence in situ hybridization and ChIP-quantitative PCR.

The in vitro antibacterial activity of essential oils (EOs) obtained from fresh bulbs of garlic, Allium sativum L., and leek, Allium porrum L. ( Alliaceae), was studied. A. sativum (garlic) EO showed a good antimicrobial activity against Staphylococcus aureus (inhibition zone 14.8 mm), Pseudomonas aeruginosa (inhibition zone 21.1 mm), and Escherichia coli (inhibition zone 11.0 mm), whereas the EO of A. porrum (leek) had no antimicrobial activity. The main constituents of the garlic EO were diallyl monosulfide, diallyl disulfide (DADS), diallyl trisulfide, and diallyl tetrasulfide. The EO of A. porrum was characterized by the presence of dipropyl disulfide (DPDS), dipropyl trisulfide, and dipropyl tetrasulfide. The antimicrobial activities of the DADS and DPDS were also studied. The results obtained suggest that the presence of the allyl group is fundamental for the antimicrobial activity of these sulfide derivatives when they are present in Allium or in other species (DADS inhibition zone on S. aureus 15.9 mm, P. aeruginosa 21.9 mm, E. coli 11.4 mm).

Cardiovascular diseases are major health complications currently in various societies. Management of heart diseases as a prevention step or as treatment with low-cost procedures like lifestyle modifications including nutrition are important current trends. Although the term nutrition dates back to 2 past centuries, Persian physicians contributed to this term at least from 1000 years ago. Rhazes (865-925 AD) was one of the pioneers in this field. He preferred using foods in treating illnesses. "Foods and drinks" were 1 subject from 6 principles (Setteh Zarorieh) that Persian physicians believed can affect human health. In this review, we described some medieval Persian views on the role of nutrition in heart diseases and compare their prescriptions with current findings. Interestingly, current investigations mostly support Persian medicine principles. Historically, this work shows that the concept of nutrition in heart diseases has had a successful background at least from 1000 years ago in Persia. © The Author(s) 2014.

The most common cognitive disorder that is disabling is dementia. During the medieval period, traditional Persian medicine was an outstanding source of medicine that was used as standard references in medical schools of in the West and Middle East. In ancient manuscripts of traditional Persian medicine, a condition has been introduced similar to dementi (raoonat and homgh). In this article, by collecting materials of traditional medicine texts on dementia, we aim to provide theories for further studies on this topics, as there is an obvious difference between traditional Persian medicine and modern medicine with regard to dementia; however, since modern medicine has not found a suitable response to treatment for all diseases, reviewing traditional Persian medicine for finding better treatment strategies is wise. Use of all medical potentials approved by the World Health Organization beside classic medicine like traditional medicine and considering the availability and acceptability among people is recommended. © The Author(s) 2015.

The Dysphagia Handicap Index (DHI) is one of the instruments used for measuring a dysphagic patient's self-assessment. In some ways, it reflects the patient's quality of life. Although it has been recognized and widely applied in English speaking populations, it has not been used in its present forms in Persian speaking countries. The purpose of this study was to adapt a Persian version of the DHI and to evaluate its validity, consistency, and reliability in the Persian population with oropharyngeal dysphagia. Some stages for cross-cultural adaptation were performed, which consisted in translation, synthesis, back translation, review by an expert committee, and final proof reading. The generated Persian DHI was administered to 85 patients with oropharyngeal dysphagia and 89 control subjects at Zahedan city between May 2013 and August 2013. The patients and control subjects answered the same questionnaire 2 weeks later to verify the test-retest reliability. Internal consistency and test-retest reliability were evaluated. The results of the patients and the control group were compared. The Persian DHI showed good internal consistency (Cronbach's alpha coefficients range from 0.82 to 0.94). Also, good test-retest reliability was found for the total scores of the Persian DHI (r=0.89). There was a significant difference between the DHI scores of the control group and those of the oropharyngeal dysphagia group (P‹0.001). The Persian version of the DHI achieved Face and translation validity. This study demonstrated that the Persian DHI is a valid tool for self-assessment of the handicapping effects of dysphagia on the physical, functional, and emotional aspects of patient life and can be a useful tool for screening and treatment planning for the Persian-speaking dysphagic patients, regardless of the cause or the severity of the dysphagia.

The Role of the Persian Gulf in Shaping Southwest Asian Surface Climate

NASA Astrophysics Data System (ADS)

Pal, J. S.; Eltahir, E. A. B.

2015-12-01

Summer surface climate of the Persian Gulf region is characterized by hot and humid conditions. Despite such conditions - which in other regions tends to trigger moist convection - typically this region experiences clear sky conditions and very little rainfall in the summer. In this study, we customize the MIT Regional Climate Model specifically for the Southwest Asia region and apply it at a 25-km grid spacing using reanalysis boundary conditions for present-day climate (1975-2005). Specific customizations include accurate representations of surface albedo and emissivity as well as mineral dust processes, all of which improve model bias. To assess the role of the Persian Gulf in shaping the region's climate, a 30-year experiment is performed without the Persian Gulf characterized. Results suggest that observed conditions over the Persian Gulf are due to a combination of physical processes involving adiabatic and diabatic descent. First, virtually clear sky conditions, due to subsidence during summer associated with the rising air motion over the monsoon region to the east, suppress upward motion and deep convection and increase incoming solar radiation. Second, the low surface albedo of the Persian Gulf results in enhanced absorption of solar radiation and total heat flux. Third, high evaporation rates increase water vapor, and therefore trap heat at the surface via the greenhouse effect for water vapor. Fourth, the relatively shallow boundary layer over the Persian Gulf concentrates water vapor and heat close to the surface. These combined factors maximize the total flux of heat in the boundary layer and hence moist static energy over the Persian Gulf.

2010-01-01

Introduction: Diabetic Neuropathy (DN) is a major microvascular complication of uncontrolled diabetes. This may result from increased oxidative stress that accompanies diabetes. Hence plants with antioxidant action play an important role in management of diabetes and its complications. Materials and Methods: This study was designed to evaluate preventive as well as curative effect of methanol extracts of outer scales and edible portions of two plants with established antioxidant action - Allium cepa and Allium sativum, in induced DN in albino mice. Mice were divided into control, diabetic and test extracts treated groups. Test extracts were administered daily at a dose of 200 mg/kg p.o. for 21 days, in the preventive group prior to onset of DN, and in the curative group after the onset of DN. Hyperalgesia and oxidative stress markers were assessed. STZ-diabetic mice showed a significant thermal hyperalgesia (as assessed by the tail-flick test), indicating development of DN. Results: Treatment with test extracts prevented loss in body weight, decreased plasma glucose level, and significantly ameliorated the hyperalgesia, TBARS, serum nitrite and GSH levels in diabetic mice. Conclusion: Methanol extract of outer scales of onion has shown most significant improvement; may be due to higher content of phenolic compounds in outer scales of A. cepa. PMID:21713142

Cognitive impairment in patients with Parkinson's disease (PD) mainly involves executive function (EF). The frontal assessment battery (FAB) is an efficient tool for the assessment of EFs. The aims of this study were to determine the validity and reliability of the psychometric properties of the Persian version of FAB and assess its correlation with formal measures of EFs to provide normative data for the Persian version of FAB in patients with PD. The study recruited 149 healthy participants and 49 patients with idiopathic PD. In PD patients, FAB results were compared to their performance on EF tests. Reliability analysis involved test-retest reliability and internal consistency, whereas validity analysis involved convergent validity approach. FAB scores compared in normal controls and in PD patients matched for age, education, and Mini-Mental State Examination (MMSE) score. In PD patients, FAB scores were significantly decreased compared to normal controls, and correlated with Stroop test and Wisconsin Card Sorting Test (WCST). In healthy subjects, FAB scores varied according to the age, education, and MMSE. In the FAB subtest analysis, the performances of PD patients were worse than the healthy participants on similarities, fluency tasks, and Luria's motor series. Persian version of FAB could be used as a reliable scale for the assessment of frontal lobe functions in Iranian patients with PD. Furthermore, normative data provided for the Persian version of this test improve the accuracy and confidence in the clinical application of the FAB.

Oxford shoulder score is a specific 12-item patient-reported tool for evaluation of patients with inflammatory and degenerative disorders of the shoulder. Since its introduction, it has been translated and culturally adapted in some Western and Eastern countries. The aim of this study was to translate the Oxford Shoulder Score (OSS) in Persian and to test its validity and reliability in Persian speaking population in Iran. One hundred patients with degenerative or inflammatory shoulder problem participated in the survey in 2012. All patients completed the Persian version of OSS, Persian DASH and the SF-36 for testing validity. Randomly, 37 patients filled out the Persian OSS again three days after the initial visit to assess the reliability of the questionnaire. Cronbach's alpha coefficient was 0.93. The intraclass correlation coefficient was 0.93. In terms of validity, there was a significant correlation between the Persian OSS and DASH and SF-36 scores (P < 0.001). The Persian version of the OSS proved to be a valid, reliable, and reproducible tool as demonstrated by high Cronbach's alpha and Pearson's correlation coefficients. The Persian transcript of OSS is administrable to Persian speaking patients with shoulder condition and it is understandable by them.

The present study deals with the valorization of an edible spontaneous plant of the Tunisian arid areas: Allium roseum. This plant is traditionally used for therapeutic and culinary uses. Thin-layer drying behavior of Allium roseum leaves was investigated at 40, 50 and 60 °C drying air temperatures and 1 and l.5 m/s air velocity, in a convective dryer. The increase in air temperature significantly affected the moisture loss and reduced the drying time while air velocity was an insignificant factor during drying of Allium roseum leaves. Five models selected from the literature were found to satisfactorily describe drying kinetics of Allium roseum leaves for all tested drying conditions. Drying data were analyzed to obtain moisture diffusivity values. During the falling rate-drying period, moisture transfer from Allium roseum leaves was described by applying the Fick's diffusion model. Moisture diffusivity varied from 2.55 × 10(-12) to 8.83 × 10(-12) m(2)/s and increased with air temperature. Activation energy during convective drying was calculated using an exponential expression based on Arrhenius equation and ranged between 46.80 and 52.68 kJ/mol. All sulfur compounds detected in the fresh leaves were detected in the dried leaves. Convective air drying preserved the sulfur compounds potential formation.

Background: Finding the right word is a necessity in communication, and its evaluation has always been a challenging clinical issue, suggesting the need for valid and reliable measurements. The Homophone Meaning Generation Test (HMGT) can measure the ability to switch between verbal concepts, which is required in word retrieval. The purpose of this study was to adapt and validate the Persian version of the HMGT. Methods: The first phase involved the adaptation of the HMGT to the Persian language. The second phase concerned the psychometric testing. The word-finding performance was assessed in 90 Persian-speaking healthy individuals (20-50 year old; 45 males and 45 females) through three naming tasks: Semantic Fluency, Phonemic Fluency, and Homophone Meaning Generation Test. The participants had no history of neurological or psychiatric diseases, alcohol abuse, severe depression, or history of speech, language, or learning problems. Results: The internal consistency coefficient was larger than 0.8 for all the items with a total Cronbach’s alpha of 0.80. Interrater and intrarater reliability were also excellent. The validity of all items was above 0.77, and the content validity index (0.99) was appropriate. The Persian HMGT had strong convergent validity with semantic and phonemic switching and adequate divergent validity with semantic and phonemic clustering. Conclusion: The Persian version of the Homophone Meaning Generation Test is an appropriate, valid, and reliable test to evaluate the ability to switch between verbal concepts in the assessment of word-finding performance.

Garlic is widely used as a spice throughout the world for the culinary value of its flavor and aroma, which are created by the chemical transformation of a series of organic sulfur compounds. To analyze the transcriptome of Allium sativum and discover the genes involved in sulfur metabolism, cDNAs derived from the total RNA of Allium sativum buds were analyzed by Illumina sequencing. Approximately 26.67 million 90 bp paired-end clean reads were achieved in two libraries. A total of 127,933 unigenes were generated by de novo assembly and were compared with the sequences in public databases. Of these, 45,286 unigenes had significant hits to the sequences in the Nr database, 29,514 showed significant similarity to known proteins in the Swiss-Prot database and, 20,706 and 21,952 unigenes had significant similarity to existing sequences in the KEGG and COG databases, respectively. Moreover, genes involved in organic sulfur biosynthesis were identified. These unigenes data will provide the foundation for research on gene expression, genomics and functional genomics in Allium sativum. Key message The obtained unigenes will provide the foundation for research on functional genomics in Allium sativum and its closely related species, and fill the gap of the existing plant EST database.

2017-01-01

Bioassay-based approaches have been propagated to assess toxicity of unknown mixtures of environmental contaminants, but it was rarely applied in cases of chemicals with radionuclides combinations. Two Allium-test studies were performed to assess environmental impact from potential sources of combined radioactive-chemical pollution. Study sites were located at nuclear waste storage facilities in European and in Far-Eastern parts of Russia. As environmental media under impact, waters from monitor wells and nearby water bodies were tested. Concentrations of some chemicals and radionuclides in the samples collected enhanced the permitted limits. Cytogenetic and cytotoxic effects were used as biological endpoints, namely, frequency and spectrum of chromosome aberrations and mitotic abnormalities in anatelophase cells as well as mitotic activity in Allium root tips. Sample points were revealed where waters have an enhanced mutagenic potential. The findings obtained could be used to optimize monitoring system and advance decision making on management and rehabilitation of industrial sites. The Allium-test could be recommended and applied as an effective tool for toxicity testing in case of combined contamination of environmental compartments with radionuclides and chemical compounds.

Phytoplankton bloom in Persian Gulf

NASA Technical Reports Server (NTRS)

2002-01-01

There is a large amount of sediment clearly visible in the true-color image of the Persian Gulf, acquired on November 1, 2001, by MODIS. Carried by the confluence of the Tigris and Euphrates Rivers (at center), the sediment-laden waters appear light brown where they enter the northern end of the Persian Gulf and then gradually dissipate into turquoise swirls as they drift southward. The nutrients these sediments carry are helping to support a phytoplankton bloom in the region, which adds some darker green hues in the rich kaleidoscope of colors on the surface (see the high resolution image). The confluence of the Tigris and Euphrates Rivers marks the southernmost boundary between Iran (upper right) and Iraq (upper left). South of Iraq are the countries of Kuwait and Saudi Arabia. The red dots indicate the probable locations of fires burning at oil refineries. Thin black plumes of smoke can be seen streaming away from several of these.

2016-09-01

Baecke Habitual Physical Activity Questionnaire (BHPAQ) has widely been employed in clinical and laboratorial studies as a tool for measuring subjects' physical activities. But, the reliability and validity of this questionnaire have not been investigated among Persian speakers. Therefore, the aim of the current study was examining the reliability and validity of the Persian version of the BHPAQ in healthy Persian adults. After following the process of forward-backward translation, 32 subjects were invited to fill out the Persian version of the questionnaire in two independent sessions (3 - 7 days after the first session) in order to determine the reliability index. Also, the validity of the questionnaire was assessed through concurrent validity by 126 subjects (66 males and 60 females) answering both the Baecke and the International Physical Activity Questionnaire (IPAQ). An acceptable level of intraclass correlation coefficient (ICC of work score = 0.95, sport score = 0.93, and leisure score = 0.77) was achieved for the Persian Baecke questionnaire. Correlations between Persian Baecke and IPAQ with and without the score for sitting position were found to be 0.19 and 0.36, respectively. The Persian version of the BHPAQ is a reliable and valid instrument that can be used to measure the level of habitual functional activities in Persian-speaking subjects.

Background: Garlics and onions have been used for the treatment of diseases caused by parasites and microbes since ancient times. Trypanosomiasis and leishmaniasis are a concern in many areas of the world, especially in poor countries. Methods: Trypanosoma brucei brucei and Leishmania tarentolae were used to investigate the anti-parasitic effects of dichloromethane extracts of Allium sativum (garlic) and Allium cepa (onion) bulbs. As a confirmation of known antimicrobial activities, they were studied against a selection of G-negative, G-positive bacteria and two fungi. Chemical analyses were performed using high-performance liquid chromatography (HPLC) and electrospray ionization-mass spectrometry (LC-ESI-MS/MS). Results: Chemical analyses confirmed the abundance of several sulfur secondary metabolites in garlic and one (zwiebelane) in the onion extract. Both extracts killed both types of parasites efficiently and inhibited the Trypanosoma brucei trypanothione reductase irreversibly. In addition, garlic extract decreased the mitochondrial membrane potential in trypanosomes. Garlic killed the fungi C. albicans and C. parapsilosis more effectively than the positive control. The combinations of garlic and onion with common trypanocidal and leishmanicidal drugs resulted in a synergistic or additive effect in 50% of cases. Conclusion: The mechanism for biological activity of garlic and onion appears to be related to the amount and the profile of sulfur-containing compounds. It is most likely that vital substances inside the parasitic cell, like trypanothione reductase, are inhibited through disulfide bond formation between SH groups of vital redox compounds and sulfur-containing secondary metabolites.

Aphasia in Persian: Implications for cognitive models of lexical processing.

Current models of oral reading assume that different routes (sublexical, lexical, and semantic) mediate oral reading performance and reliance on different routes during oral reading depends on the characteristics of print to sound mappings. Studies of single cases of acquired dyslexia in aphasia have contributed to the development of such models by revealing patterns of double dissociation in object naming and oral reading skill that follow brain damage in Indo-European and Sino-Tibetan languages. Print to sound mapping in Persian varies in transparency because orthography to phonology translation depends uniquely on the presence or absence of vowel letters in print. Here a hypothesis is tested that oral reading in Persian requires a semantic reading pathway that is independent of a direct non-semantic reading pathway, by investigating whether Persian speakers with aphasia show selective impairments to object naming and reading aloud. A sample of 21 Persian speakers with aphasia ranging in age from 18 to 77 (mean = 53, SD = 16.9) was asked to name a same set of 200 objects and to read aloud the printed names of these objects in different sessions. As an additional measure of sublexical reading, patients were asked to read aloud 30 non-word stimuli. Results showed that oral reading is significantly more preserved than object naming in Persian speakers with aphasia. However, more preserved object naming than oral reading was also observed in some cases. There was a moderate positive correlation between picture naming and oral reading success (p < .05). Mixed-effects logistic regression revealed that word frequency, age of acquisition and imageability predict success across both tasks and there is an interaction between these variables and orthographic transparency in oral reading. Furthermore, opaque words were read less accurately than transparent words. The results reveal different patterns of acquired dyslexia in some cases that closely resemble phonological

Due to negligence, Persian (Iranian) traditional medicine has had a weak presence in the world of research for a long time. However, in recent years, a variety of activates by research and faculty centers have created awareness and a platform to introduce and promote Persian medicine to the world. The aim of this study is to present and analyze scientific achievements of Persian medicine in the world of research. Articles were collected from PubMed database using keywords such as "Persian medicine", "Persian traditional medicine", "Iranian medicine", and "Iranian traditional medicine". All data were classified based on the type of research (review, intervention, case reports, etc.), the field of study (neurology, cardiovascular, metabolic, historical studies, etc.), publication year, and journal type. A total of 501 articles were identified until the end of 2015, comprising of 222 reviews and 219 interventional (108 animal, 57 clinical and 54 cellular). Most studies were on neurology (20.1%), gastroenterology (14.5%), and cardiovascular diseases (10.4%). The publications in 2015 and 2014 had the highest hit rate with 139 and 132 articles, respectively, with 1:2 publication ratio between foreign and Iranian journals. The most published articles, both foreign and Iranian, were in "Evidence-Based Complementary and Alternative Medicine" and "Iranian Red Crescent Medicine" journals. The contribution of foreign authors was 5%. The primary focus of the articles was on "Basic concepts of Persian medicine", "Healthy lifestyle according to Persian medicine", and "Historical aspects", by 3.1%, 2.9%, and 6.7%, respectively. During the last 2 years, the number of articles published in Persian (Iranian) medicine, particularly clinical studies had significant growth in comparison with the years before. The tendency of foreign researchers to use the keywords "Iranian" or "Persian" medicine is notable. This research was only based on the designated keyword and other keywords were

The Internet has provided great opportunities for disseminating both accurate and inaccurate health information. Therefore, the quality of information is considered as a widespread concern affecting the human life. Despite the increasingly substantial growth in the number of users, Persian health websites and the proportion of internet-using patients, little is known about the quality of Persian medical and health websites. The current study aimed to first assess the quality, popularity and importance of websites providing Persian health-related information, and second to evaluate the correlation of the popularity and importance ranking with quality score on the Internet. The sample websites were identified by entering the health-related keywords into four most popular search engines of Iranian users based on the Alexa ranking at the time of study. Each selected website was assessed using three qualified tools including the Bomba and Land Index, Google PageRank and the Alexa ranking. The evaluated sites characteristics (ownership structure, database, scope and objective) really did not have an effect on the Alexa traffic global rank, Alexa traffic rank in Iran, Google PageRank and Bomba total score. Most websites (78.9 percent, n = 56) were in the moderate category (8 ≤ x ≤ 11.99) based on their quality levels. There was no statistically significant association between Google PageRank with Bomba index variables and Alexa traffic global rank (P > 0.05). The Persian health websites had better Bomba quality scores in availability and usability guidelines as compared to other guidelines. The Google PageRank did not properly reflect the real quality of evaluated websites and Internet users seeking online health information should not merely rely on it for any kind of prejudgment regarding Persian health websites. However, they can use Iran Alexa rank as a primary filtering tool of these websites. Therefore, designing search engines dedicated to explore accredited

Background and Aims The genus Allium comprises more than 800 species, placing it among the largest monocotyledonous genera. It is a variable group that is spread widely across the Holarctic region. Previous studies of Allium have been useful in identifying and assessing its evolutionary lineages. However, there are still many gaps in our knowledge of infrageneric taxonomy and evolution of Allium. Further understanding of its phylogeny and biogeography will be achieved only through continued phylogenetic studies, especially of those species endemic to China that have often been excluded from previous analyses. Earlier molecular studies have shown that Chinese Allium is not monophyletic, so the goal of the present study was to infer the phylogeny and biogeography of Allium and to provide a classification of Chinese Allium by placement of Chinese species in the context of the entire phylogeny. Methods Phylogenetic studies were based on sequence data of the nuclear ribosomal internal transcribed spacer (ITS) and chloroplast rps16 intron, analysed using parsimony and Bayesian approaches. Biogeographical patterns were conducted using statistical dispersal–vicariance analysis (S-DIVA). Key Results Phylogenetic analyses indicate that Allium is monophyletic and consists of three major clades. Optimal reconstructions have favoured the ancestors of Amerallium, Anguinum, Vvedenskya, Porphyroprason and Melanocrommyum as originating in eastern Asia. Conclusions Phylogenetic analyses reveal that Allium is monophyletic but that some subgenera are not. The large genetic distances imply that Allium is of ancient origin. Molecular data suggest that its evolution proceeded along three separate evolutionary lines. S-DIVA indicates that the ancestor of Amerallium, Anguinum, Vvedenskya, Porphyroprason and Melanocrommyum originated from eastern Asia and underwent different biogeographical pathways. A taxonomic synopsis of Chinese Allium at sectional level is given, which divides Chinese

Pruritus is an unpleasant feeling that can cause the desire of scratching in a person and can be the symptoms of systemic, infectious, and neurological diseases. Pruritus is the most common clinical manifestation of skin diseases. Pruritus prevalence is 8-38% in the general population. Causes and treatments of pruritus have been described by traditional Persian medicine scientists. The aim of this study was to derive general principles of the proposed treatment to reduce or relieve pruritus. This descriptive study, review traditional medicine books including Al canon fil tibb, Al-Hawi, Makhzan ul-adviyyah, Al-Abniyah an-Haghyegh el-adviyah, Tuhfat ul-Momineen and Exir-e-Azam. The above-mentioned documents were derived and classified by keywords such as pruritus, hakka, jarab and sherry. In traditional Persian medicine, there are different causes for pruritus such as accumulation of vapors or acute humors in subcutaneous tissue or weakness of expulsive (Dafi'a) faculty and its treatment is based on removing the causes. Proper nutrition, bathing, and removing pathogenic humors are involved in the treatment. According to this study, some plants such as Cassia fistula, Purslane, Violets, Fumaria, Barley, Coriander, Rose and Terminalia chebula are anti-itching. Proper nutrition is the most important point in health and treatment of humors production with appropriate quality and quantity. Pruritus can be treated by lifestyle modification and using medicinal plants. It could be concluded that traditional Persian medicine therapies can be effective in the treatment of pruritus with mild side effects. By further investigation and research, we can reach more effective treatment methods in the field of traditional Persian medicine along with other new medical therapies.

The Multiple Sclerosis Walking Scale-12 (MSWS-12) is a multi-item rating scale used to assess the perspectives of patients about the impact of MS on their walking ability. The aim of this study was to examine the reliability and validity of the MSWS-12 in Persian speaking patients with MS. The MSWS-12 questionnaire was translated into Persian language according to internationally adopted standards involving forward-backward translation, reviewed by an expert committee and tested on the pre-final version. In this cross-sectional study, 100 participants (50 patients with MS and 50 healthy subjects) were included. The MSWS-12 was administered twice 7 days apart to 30 patients with MS for test and retest reliability. Internal consistency reliability was Cronbach's α 0.96 for test and 0.97 for retest. There were no significant floor or ceiling effects. Test-retest reliability was excellent (intraclass correlation coefficient [ICC] agreement of 0.98, 95% CI, 0.95-0.99) confirming the reproducibility of the Persian MSWS-12. Construct validity using known group methods was demonstrated through a significant difference in the Persian MSWS-12 total score between the patients with MS and healthy subjects. Factor analysis extracted 2 latent factors (79.24% of the total variance). A second factor analysis suggested the 9-item Persian MSWS as a unidimensional scale for patients with MS. The Persian MSWS-12 was found to be valid and reliable for assessing walking ability in Persian speaking patients with MS. Copyright © 2014 Elsevier B.V. All rights reserved.

This study aimed at investigating the effects of dietary Allium sativum (garlic, G) and Allium cepa (onion, O) on immune functions in White Leghorn chicken. One-week-old chicks, were fed diets without (control) or with Alliums (GL and OL, 10 g or GH and OH, 30 g/kg diet). Chickens were immunized with Newcastle disease virus (NDV), sheep red blood cells (SRBC) and Brucella abortus (BA). Antibodies, lymphocyte proliferation, and ratios of CD4(+) , CD8(+) and CD4⁻ CD8⁻ lymphocytes were investigated. Histology and weights of the spleen, thymus and bursa (BF), and white blood cell (WBC) counts were studied as well. Alliums at 10 g/kg diet enhanced anti-NDV, anti-SRBC and anti-BA antibody productions, whereas 30 g/kg diet had less stimulatory effects. Histology of the lymphoid organs and proliferation of peripheral blood lymphocytes (PBL) were not influenced. However, splenocyte and thymocyte proliferations were augmented with garlic. Flow cytometry analysis showed reduction in CD4(+) and increase in CD4⁻ CD8⁻ lymphocyte ratios in GH and OH groups. Garlic-supplemented chickens had heavier spleen and thymus, and higher WBC counts, whereas BF weight increased with both Alliums at 30 g/kg diet. These results suggest that dietary Alliums have a potential to enhance the immune functions in White Leghorn chickens. © 2010 The Authors.

It has been shown that smoking may be affected by metacognitions. This study aimed to evaluate the factor structure, reliability and validity of the Persian version of the Metacognitions about Smoking Questionnaire (MSQ) among a sample of Iranian male smokers. When the English to Persian translation of the MSQ was performed, exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were completed according to the four-factor solution of the original MSQ. Three hundred male treatment-seeking smokers (mean age = 41.37, SD = 15.90) filled out the Persian-translated version of the MSQ, the Smoking Effects Questionnaire (SEQ), and the Nicotine Dependence Syndrome Scale (NDSS). The results of EFA revealed that the Persian version of the MSQ had a four-factor structure named positive metacognitions about cognitive regulation (PM-CR), positive metacognitions about emotional regulation (PM-ER), negative metacognitions about uncontrollability (NM-U), and negative metacognitions about cognitive interference (NM-CI). The findings of CFA also indicated that the four-factor structure of the Persian version of the MSQ had appropriate fit. Validity and reliability of the Persian version of the MSQ were found to be good. Negative metacognitions about smoking predicted nicotine dependence over and above smoking outcome expectancies. Positive metacognitions about emotion regulation explained daily cigarette use independent of smoking outcome expectancies. The findings suggested that the Persian version of the MSQ had adequate psychometric properties among Iranian male treatment-seeking smokers. Copyright © 2018 Elsevier Ltd. All rights reserved.

Cat breeders observed a frequent occurrence of internal hydrocephalus in Persian cats with extreme brachycephalic head morphology. To investigate a possible relationship among the grade of brachycephaly, ventricular dilatation, and skull dysmorphologies in Persian cats. 92 Persian-, 10 Domestic shorthair cats. The grade of brachycephaly was determined on skull models based on CT datasets. Cranial measurements were examined with regard to a possible correlation with relative ventricular volume, and cranial capacity. Persians with high (peke-face Persians) and lower grades of brachycephaly (doll-face Persians) were investigated for the presence of skull dysmorphologies. The mean cranial index of the peke-face Persians (0.97 ± 0.14) was significantly higher than the mean cranial index of doll-face Persians (0.66 ± 0.04; P < 0.001). Peke-face Persians had a lower relative nasal bone length (0.15 ± 0.04) compared to doll-face (0.29 ± 0.08; P < 0.001). The endocranial volume was significantly lower in doll-face than peke-face Persians (89.6 ± 1.27% versus 91.76 ± 2.07%; P < 0.001). The cranial index was significantly correlated with this variable (Spearman's r: 0.7; P < 0.0001). Mean ventricle: Brain ratio of the peke-face group (0.159 ± 0.14) was significantly higher compared to doll-face Persians (0.015 ± 0.01; P < 0.001). High grades of brachycephaly are also associated with malformations of the calvarial and facial bones as well as dental malformations. As these dysmorphologies can affect animal welfare, the selection for extreme forms of brachycephaly in Persian cats should be reconsidered. Copyright © 2017 The Authors.

Tinnitus is a common otologic symptom that can seriously affect a patient's quality of life. The purpose of the present study was to translate and validate the Iowa Tinnitus Handicap Questionnaire (THQ) into the Persian language, and to make it applicable as a tool for determining the effects of tinnitus on a patient's life. The main version of the THQ was translated into the Persian language. The agreed Persian version was administered to 150 tinnitus patients. The validity of the Persian THQ was evaluated and internal reliability was confirmed using Cronbach's α-coefficient. Finally, the effect of independent variables such as age, mean patient threshold, gender, and duration of tinnitus were considered in order to determine the psychometric properties of tinnitus. After an exact translation process, the Persian THQ was found to exhibit face validity. In terms of content validity, content validity index in total questionnaire was 0.93. Further, in structural validity measurements, intermediate correlation with annoyance from tinnitus (r=0.49), low correlation with duration of tinnitus (r=0.34) and high correlation with the Tinnitus Handicap Inventory (THI) questionnaire (r=0.84) were demonstrated. Additionally, a negligible effect of gender and age was noted on degree of tinnitus handicap (P= 0.754, P= 0.573, respectively). In the internal reliability assessment for Factors 1, 2, 3, and the whole questionnaire, Cronbach`s α-coefficient was 0.95, 0.92, 0.25 and 0.88, respectively. The Persian version of the Iowa THQ demonstrates high validity and reliability and can be used for the determination of tinnitus handicap and for following-up in the intervention process in Persian tinnitus patients.

We aimed to validate a cross-culturally adapted version of the Persian Michigan Hand Outcomes Questionnaire (MHOQ). We followed the Beaton's guideline to translate the questionnaire to Persian. We administered the final version to 223 patients among which 79 patients returned 3 days later to respond to the Persian MHOQ for the second time. In the first visit, respondents also filled the Disabilities of the Arm Shoulder and Hand (DASH) and rated the pain based on the Visual Analogue Scale (VAS). Cronbach's alpha for the total MHOQ was 0.79 which showed good internal consistency. Intraclass correlation coefficient (ICC) for the total MHOQ was 0.84 which demonstrated good reliability between test and retest. The absolute correlation coefficient between total MHOQ and the DASH was as high as 0.74. Persian version of the MHOQ proved to be a reliable and valid instrument to be implemented among Persian population with the hand and wrist disorders.

Spironucleus is a genus of small, flagellated parasites, many of which can infect a wide range of vertebrates and are a significant problem in aquaculture. Following the ban on the use of metronidazole in food fish due to toxicity problems, no satisfactory chemotherapies for the treatment of spironucleosis are currently available. Using membrane inlet mass spectrometry and automated optical density monitoring of growth, we investigated in vitro the effect of Allium sativum (garlic), a herbal remedy known for its antimicrobial properties, on the growth and metabolism of Spironucleus vortens, a parasite of tropical fish and putative agent of hole-in-the-head disease. The allium-derived thiosulfinate compounds allicin and ajoene, as well as an ajoene-free mixture of thiosulfinates and vinyl-dithiins were also tested. Whole, freeze-dried garlic and allium-derived compounds had an inhibitory effect on gas metabolism, exponential growth rate and final growth yield of S. vortens in Keister's modified, TY-I-S33 culture medium. Of all the allium-derived compounds tested, the ajoene-free mixture of dithiins and thiosulfinates was the most effective with a minimum inhibitory concentration (MIC) of 107 μg ml(-1) and an inhibitory concentration at 50% (IC(50%)) of 58 μg ml(-1). It was followed by ajoene (MIC = 83 μg ml(-1), IC(50%) = 56 μg ml(-1)) and raw garlic (MIC >20 mg ml(-1), IC(50%) = 7.9 mg ml(-1)); allicin being significantly less potent with an MIC and IC(50%) above 160 μg ml(-1). All these concentrations are much higher than those reported to be required for the inhibition of most bacteria, protozoa and fungi previously investigated, indicating an unusual level of tolerance for allium-derived products in S. vortens. However, chemically synthesized derivatives of garlic constituents might prove a useful avenue for future research. Copyright © 2010 Elsevier Inc. All rights reserved.

The aim of the present study was to develop and provide validation statistics for the Persian Injury-Psychological Readiness to Return to Sport scale (I-PRRS) following a cross-sectional and prospective cohort study design. The I-PRRS was forward/back-translated and culturally adapted into Persian language. The Persian I-PRRS was administered to 100 injured athletes (93 male; age 26.0 ± 5.6 years; time since injury 4.84 ± 6.4 months) and 50 healthy athletes (36 male; mean age 25.7 ± 6.0 years). The Persian I-PRRS was re-administered to 50 injured athletes at 1 week to examine test-retest reliability. There were no floor or ceiling effects confirming the content validity of Persian I-PRRS. The internal consistency reliability was good. Excellent test-retest reliability and agreement were demonstrated. The statistically significant difference in Persian I-PRRS total scores between the injured athletes and healthy athletes provides an evidence of discriminative validity. The Persian I-PRRS total scores were positively correlated with the Farsi Mood Scale (FARMS) total scores, showing construct validity. The principal component analysis indicated a two-factor solution consisting of "Confidence to play" and "Confidence in the injured body part and skill level". The Persian I-PRRS showed excellent reliability and validity and can be used to assess injured athletes' psychological readiness to return to sport among Persian-speaking populations.

The Revised Fibromyalgia Impact Questionnaire (FIQR), an updated version of the Fibromyalgia Impact Questionnaire (FIQ) achieved a better balance among different domains (i.e., function, overall impact, and symptom severity) and attempts to address the limitations of FIQ. As there is no Persian version of the FIQR available, we aimed to investigate the validity and reliability of a Persian translation of the FIQR in Iranian patients. After translating the FIQR into Persian, it was administered to 77 female patients with fibromyalgia syndrome. All of the patients filled out the questionnaire together with a Persian version of the FIQ, short form-12 (SF-12). The tender-point count was also calculated. One week later, FM patients filled out the Persian FIQR at their second visit. Reliability was analyzed by internal consistency and reproducibility including Cronbach's α coefficient and intra-class correlation coefficient. Construct validity was evaluated by Spearman's correlation coefficient and Pearson's correlation coefficient. Statistical analysis was performed using SPSS for Windows version 17.0. All patients included in this study were female, and the mean age was 38.23 ± 10.68 years. The total scores of the FIQR and FIQ were 49.77 ± 18.27 and 54.05 ± 14.00 that were closely correlated (r = 0.63, p < 0.01), and each of the three domains of the Persian FIQR was also correlated well with the three related FIQ domains (r = 0.36-0.63, p < 0.01). Also some significant inverse correlations of FIQR with quality-of-life (assessed by SF-12) domains and items were found. Cronbach's α was 0.87 for FIQR in the first visit. The Persian FIQR showed adequate reliability and validity. This instrument can be used in the clinical evaluation of Iranian patients with fibromyalgia.

Background: Functional gastrointestinal diseases are common in general populations and comprise more than 40% visits to gastroenterologists. Treatment options of gastrointestinal diseases have been limited. There are a few medications for functional gastrointestinal diseases and some of medications are not available in the market or in the place where the patient lives. Traditional Persian medicine (TPM) is a branch of alternative and traditional medicine based on individual viewpoint and humoral theory, focuses on lifestyle modification and uses natural products to manage the patients. Methods: In this study, a set of compound drugs known as digesters (jawarishes) and other applications are described based on main TPM text books. Results: Jawarishes have different formulations containing various medicinal herbs used for better food digestion and improved gastric functions and also used for other disorders including reinforcing the brain, heart, liver and some therapeutic approaches. Conclusions: By reviewing medieval Persian pharmaceutical manuscripts, we can conclude that many herbs are effective in different systems of the body and improve gastric functions. Zingiber officinalis and Piper nigrum are mixed together to get various formulations. The variety of jawarishes formulations and their different clinical applications can indicate continuity of their use. PMID:29387312

The Functional index of hand osteoarthritis (FIHOA) is a commonly used patient-reported outcome questionnaire designed to measure function in patients with hand osteoarthritis. The objective of this study was to evaluate the validity and reliability of the Persian version of the FIHOA. The Persian-translated version of FIHOA was administered to 72 native Persian-speaking patients in Iran with hand osteoarthritis. Thirty-six of the patients completed the questionnaire on two occasions 1 week apart. The physical component of the SF-36 and a numerical rating scale were used to evaluate the construct validity of the Persian version of FIHOA. Internal consistency was high (Cronbach's alpha = 0.89). Test-retest reliability for the total score was excellent (weighted kappa = 0.89, 95% CI 0.79-0.94). A significant positive correlation between total FIHOA score and numerical rating scale (r = 0.70) and a significant negative correlation between total FIHOA score and the physical component scale of the SF-36 (r = -0.76) were observed. The Persian version of the FIHOA showed adequate validity and reliability to evaluate functional disability in Persian-speaking patients with hand osteoarthritis.

As a result of the 1991 Persian Gulf war, between mid-January and June 1991, the Persian Gulf was contaminated with an estimated 4 to 6 million barrels of crude oil, released directly into the Gulf from refinement facilities, transhipment terminals, and moored tankers along the coast of Kuwait, and precipitated from oil fire smoke plumes. To assess the environmental impact of the oil, an international team of marine scientists representing 14 nations was assembled under the auspices of the United Nations International Oceanic Commission and the Regional Organization for Protection of the Marine Environment to conduct detailed surveys of the Persian Gulf, the Strait of Hormuz, and the Gulf of Oman, including hydrographic, chemical, and biological measurements. To supplement the field surveys and to serve as an aid in data interpretation, astronauts aboard the Space Shuttle Atlantis photographed water features and coastal habitats in the Persian Gulf during mission STS-45 (24 March to 02 April 1992). The astronauts collected 111 hand-held, color photographs of the Gulf (72 70-mm photographs and 39 5-inch photographs) from an altitude of 296 km (160 n.mi.). The photographs reveal distributions in water turbidity associated with outflow from the Shatt-al-Arab and water circulation along the entire coast of Iran and the Strait of Hormuz, coastal wetlands and shallow-water habitats, and sticks appearing in the sunglint pattern, which appear to be oil.

One of the most common global disorders is related to gastrointestinal system. Functional dyspepsia (FD) defined as upper abdominal pain and discomfort in the absence of organic ailments is a prevalent disease without any confirmed medication. The purpose of this study was to find gastric disorders which might be coincidental to FD based on traditional Persian medicine (TPM). We searched the main textbooks of TPM including Al-Havi (by Rhazes), Canon of medicine (by Avicenna), ZakhireKhawrazmshahi (by Ismail Jorjani), Moalijat-e Aghili and Makhzan Al-adviya (by Mohammad Hosein AghiliShirazi), and ExirAzam (by Hakim Azam Khan). Also, we searched Pubmed, Scopus, Science Direct, Medline, scientific information database (SID), Iranmedex and Google Scholar from 1980 to 1 August 2014 for dyspepsia, gastrointestinal disease, traditional Persian medicine, and gastric dystemperaments. There is no equivalent term for FD in traditional Persian medicine although similar signs and symptoms are visible in terms like simple cold dystemperament of stomach, indigestion, and digestion debility in TPM sources. Some treatments mentioned in TPM have shown promising results in the current experimental tests. Finding these similarities in complementary and alternative medicine (CAM) textbooks may lead to discovering new remedies for this widespread disease.

Deltamethrin is a pesticide widely used as a synthetic pyrethroid. The aim of this study was undertaken to investigate the effects of deltamethrin to induce oxidative stress and changes in biochemical parameters, hepatotoxicity and genotoxicity in female rats following a short-term (30 days) oral exposure and attenuation of these effects by Allium sativum extract. Indeed, Allium sativum is known to be a good antioxidant food resource which helps destroy free radical particles. Our results showed that deltamethrin treatment caused an increase in liver enzyme activities of aspartate transaminase (AST), alanine transaminase (ALT), alkaline phosphatase (ALP), and lactate dehydrogenase (LDH); and hepatic lipid peroxidation (LPO) level. However, it induced a decrease in activities of hepatic catalase (CAT), superoxide dismutase (SOD), and glutathione peroxidase (GPx) (p < 0.01). Allium sativum extract normalized significantly (p < 0.01) the mentioned parameters in deltamethrin-treated rats. For genotoxic evaluation, deltamethrin treatment showed a significant increase in frequencies of micronucleus in bone-marrow cells. Micronucleus formation is an indicator of chromosomal damage which has been increasingly used to detect the genotoxic potential of environmental pests. The present study showed that Allium sativum diminished the adverse effects induced by this synthetic pyrethroid insecticide.

Sexual dysfunction has been demonstrated to be related to a poor quality of life. These dysfunctions are especially prevalent among men. This cross-sectional study aimed to investigate the psychometric properties of the Persian translation of the Sexual Quality of Life–Male (SQOL-M), translated and adapted to measure sexual quality of life among Iranian men. Forward–backward procedures were applied in translating the original SQOL-M into Persian, and then the psychometric properties of the Persian translation of the SQOL-M were studied. A total of 181 participants (23-60 years old) were included in the study. Validity was assessed by construct validity using confirmatory factor analysis, convergent validity, and content validity. The international index of erectile function (IIEF) and the work ability index were used to study the convergent validity. Reliability was evaluated through internal consistency and test–retest reliability analyses. The results from confirmatory factor analysis confirmed a one-factor solution for the Persian version of the SQOL-M. Content validity of the translated measure was endorsed by 10 specialists. Pearson correlations indicated that work ability index score, dimensions of the IIEF, and the IIEF total score were positively correlated with the Persian version of the SQOL-M (p < .001). Reliability evaluation indicated a high internal consistency and test–retest reliability. The Cronbach’s alpha coefficient and intraclass correlation coefficients were .96 and .95, respectively. Results indicated that the Persian version of the SQOL-M has good to excellent psychometric properties and can be used to assess the sexual quality of life among Iranian men. PMID:26856758

The Oxford Knee Score (OKS) is a short patient-reported outcome instrument that measures pain and physical activity related to knee osteoarthritis. The purpose of this study is to evaluate, construct validity and consistent reliability of the Persian version of the OKS. The case series consisted of 80 patients who were clinically diagnosed with having knee osteoarthritis. All patients were requested to fill-in the Persian OKS and Short-Form 36 Health Survey (SF-36). Correlation analysis between the Persian versions of these two instruments was then carried out. The scores of the Persian SF-36 were used to evaluate convergent and divergent validity of the 12-item Persian OKS. From a total of 80 patients, 63 were female (79%) and the remaining 17 were male (21%) with a mean age of 52.2 years. In the present study, high Cronbach's alpha of 0.95 confirms excellent internal consistency of the Persian OKS scale similar to previous investigations. The results confirm that the Persian version of this instrument is valid and reliable, similar to its English index and its subsequent translations in different languages. The Persian OKS is a reliable instrument to evaluate knee function in patients with knee osteoarthritis and is a useful tool for outcome measurement in clinical research.

Allium vegetables and organosulfur compounds: do they help prevent cancer?

PubMed Central

Bianchini, F; Vainio, H

2001-01-01

Allium vegetables have been shown to have beneficial effects against several diseases, including cancer. Garlic, onions, leeks, and chives have been reported to protect against stomach and colorectal cancers, although evidence for a protective effect against cancer at other sites, including the breast, is still insufficient. The protective effect appears to be related to the presence of organosulfur compounds and mainly allyl derivatives, which inhibit carcinogenesis in the forestomach, esophagus, colon, mammary gland, and lung of experimental animals. The exact mechanisms of the cancer-preventive effects are not clear, although several hypotheses have been proposed. Organosulfur compounds modulate the activity of several metabolizing enzymes that activate (cytochrome P450s) or detoxify (glutathione S-transferases) carcinogens and inhibit the formation of DNA adducts in several target tissues. Antiproliferative activity has been described in several tumor cell lines, which is possibly mediated by induction of apoptosis and alterations of the cell cycle. Allium vegetables and organosulfur compounds are thus possible cancer-preventive agents. Clinical trials will be required to define the effective dose that has no toxicity in humans. PMID:11673117

The use of earths and clays for medical purposes dates back to antiquity. In recent years, there has been an increasing interest in researches on traditional remedies in the hope of discovering new drug. Iran is an ancient country with a medical backbone acquired from the experiences of ancient Persian scholars, who had made a great contribution to the development of the medical sciences. Many medical and pharmaceutical books by early Persian scientists still exist and may have the potential of leading researchers to new drug discoveries. Owing to the emergence of new and antimicrobial-resistant infections, present-day medicine has recently begun focusing on medicinal earths and clays especially as mineral antimicrobials. The current study is, therefore, aimed at gathering information regarding medicinal clays in traditional Persian medicine (TPM). Five main Persian materia medica with the key word 'tin' (clay) and current databases such as PubMed, Scopus, ScienceDirect, and Google Scholar were searched by key words 'white, green, red, maroon, violet, black, grey and pink clays' and 'pharmacological effects'. Twenty three clays were found in Persian manuscripts. Although their mineralogical compositions are unknown, different pharmacological properties have been attributed to these mineral medicaments. Clay's properties were widely used in medieval times for the treatment of infections to poisoning. They were also used in compound formulations, possibly for their pharmaceutical formulation modifying effects. Modern scientific proofs have also been found in many of the medicinal clays reported in Persian manuscripts. Although many of the reported clays are still unknown, their characterization may lead to new medicinal developments. Novel analytical methods available today make it possible to elucidate the chemical compositions of these minerals as parameters responsible for their medicinal effects.

The increased use of herbal remedies particularly in patients with kidney diseases indicated the importance of studies which focused on nephrotoxic plants. The present study aimed to review and assess the kidney-damaging herbs mentioned in the Persian medicine [PM] books. The main PM books were searched for nephrotoxic herbs and their relevant reformers traditionally proposed for preventing renal damage. PubMed, Scopus and Google Scholar were investigated for evaluation of the scientific evidence relating to the nephrotoxicity of herbs. A total of 64 plants with kidney damage potential and their reformer medicaments were recorded in 7 sources included in this review. Allium schoenoprasum and Marrubium vulgare were the most repeated and emphasized nephrotoxic plants in PM books, but there was not any relevant scientific evidence. Despite the lack of clinical studies, some evidence was found for 38% of plants that were related to renal damage. The most repeated reformers for reducing the renal side effects mainly consisted of gum tragacanth, gum Arabic, mastic gum, anise, jujube and honey and some evidence was found for their nephroprotective activities. The present study reviewed and assessed the herbs with adverse renal effects in the main PM books. Some evidence was in line with the potential nephrotoxicity of plants and their ‎reformers. Despite the lack of clinical research for evaluation of their renal damage, the herbs may be focused in term of their nephrotoxicity; and there is a need for further studies on the scientific basis of their nephrotoxicity.

The Parental Bonding Instrument (PBI) is a widely used self-report measure for quantifying key parenting styles as perceived by the child during its first 16 years. While its development study identified two key parental dimensions, subsequent studies have variably confirmed those two or argued for one or more additional parental constructs. We developed a Persian translation of the PBI and administered it to a sample of 340 high school students. The construct validity of the Persian PBI was examined by Exploratory Factor Analysis while Confirmatory Factor Analysis was used to identify the most adequate model. Analyses of the Persian PBI favored a four-factor model for both parental forms. The Persian PBI has a factorial structure consistent with constructs identified in western cultures, as well as high internal consistency and test-retest reliability. Multivariate analyses indicated significant differences between boys and girls across some factors. The PBI appears an acceptable and appropriate measure for quantifying parent-child bonding in Iranian samples. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

Background: Developmental Sentence Scoring (DSS) was developed as a numerical measurement and a clinical method based on the morphosyntactic acquisition in the English language. The aim of this study was to develop a new numerical tool similar to DSS to assess the morphosyntactic abilities in Persian-speaking children. Methods: In this cross-sectional and comparative study, the language samples of 115 typically developing Persian-speaking children aged 30 - 65 months were audio recorded during the free play and picture description sessions. The Persian Developmental Sentence Score (PDSS) and the Mean Length of Utterance (MLU) were calculated. Pearson correlation and one - way Analysis of variance (ANOVA) were used for data analysis. Results: The correlation between PDSS and MLU in morphemes (convergent validity) was significant with a correlation coefficient of 0.97 (p< 0.001). The value Cronbach's Alpha (α= 0.79) in the grammatical categories and the split-half coefficient (0.86) indicated acceptable internal consistency reliability. Conclusion: The PDSS could be used as a reliable numerical measurement to estimate the syntactic development in Persian-speaking children.

The history of astrology offers to its students a primary challenge: the complexity of its career in transmission from one cultural area to another and in transformation of its doctrines and methods to fit the interests and cultural circumstances of its eager recipients. The translation movement between the Indian and Arabic/Persian cultures is still rarely studied. In this paper I am discussing the relations (intellectual voyages) between Indian and Arabic/Persian astrological traditions from historical and cultural perspectives. By using the various examples from Sanskrit, Pahlavī, Arabic and Persian sources I try to display the intimate scientific exchanges, by emphasizing the field of astrology and divination, between two geographically close, but in a religious and philosophical sense, very different cultural areas. The conclusion is made that the influence of Hindu astro-sciences on Islamic culture was comparatively greater but the impact of the Islamic sciences on Hindus was no less significant. On both sides a fruitful process of enculturation and integration of technical astral concepts and applied methods took place.

The Schizophrenia Cognition Rating Scale (SCoRS) is an interview-based assessment of cognition that involves interviews with patients and informants. The SCoRS has shown good reliability, validity, and sensitivity to cognitive impairment in schizophrenia, with the advantage of brief administration and scoring time. The present study aimed to test the concurrent validity of the Persian version of the SCoRS. A group of 35 patients with schizophrenia and a group of 35 healthy controls received the Persian-SCoRS in the first session, and a standardized performance-based cognitive battery, the Brief Assessment of Cognition in Schizophrenia (BACS), in the second session.Our results indicated that the Persian version of the SCoRS was sensitive to cognitive impairment in the patients. The Persian SCoRS global rating was significantly associated with the composite score generated from the Persian version of the BACS and predicted functional outcomes as measured by Global Assessment of Functioning (GAF) and World Health Organization Quality of Life (WHO QOL). A Persian version of the SCoRS, an interview based measure of cognition that included informants, is related to cognitive performance and global functioning. Copyright © 2017 Elsevier B.V.

The functions of the mammalian kidney are closely related to its structure. This suggests that renal function can be completely characterized by accurate knowledge of its quantitative morphological features. The aim of this study was to investigate the histomorphometric features of the kidney using design-based and unbiased stereological methods in the Persian squirrel (Sciurus anomalus), which is the only representative of the Sciuridae family in the Middle East. The left kidneys of five animals were examined. Total volume of the kidney, cortex, and medulla were determined to be 960.75 ± 87.4, 754.31 ± 77.09 and 206.1 ± 16.89 mm 3 , respectively. The glomerular number was 32844.03 ± 1069.19, and the total glomerular volume was estimated to be 36.7 ± 1.45 mm 3 . The volume and length of the proximal convoluted tubule were estimated at 585.67 ± 60.7 mm 3 and 328.8 ± 14.8 m, respectively, with both values being greater than those reported in the rat kidney. The volume and length of the distal convoluted tubule were calculated at 122.34 ± 7.38 mm 3 and 234.4 ± 17.45 m, respectively, which are also greater than those reported in the rat kidney. Despite the comparable body weight, the total number and mean individual volume of glomeruli in the Persian squirrel kidney were greater than those in the rat kidney. Overall, the stereological variables of the kidneys elucidated in this study are exclusive to the Persian squirrel. Our findings, together with future renal physiological data, will contribute to a better understanding of the renal structure-function relationship in the Persian squirrel.

The aim of this study was to evaluate the efficacy of the treatment of acid mine drainage (AMD) with calcinated coal mining waste using Allium cepa L. as a bioindicator. The pH values and the concentrations of aluminum, iron, manganese, zinc, copper, lead and sulfate were determined before and after the treatment of the AMD with calcinated coal mining waste. Allium cepa L. was exposed to untreated and treated AMD, as well as to mineral water as a negative control (NC). At the end of the exposure period, the inhibition of root growth was measured and the mean effective concentration (EC(50)) was determined. Oxidative stress biomarkers such as lipid peroxidation (TBARS), protein carbonyls (PC), catalase activity (CAT) and reduced glutathione levels (GSH) in the fleshy leaves of the bulb, as well as the DNA damage index (ID) in meristematic cells, were evaluated. The results indicated that the AMD treatment with calcinated coal mining waste resulted in an increase in the pH and an expressive removal of aluminum, iron, manganese and zinc. A high sub-chronic toxicity was observed when Allium cepa L. was exposed to the untreated AMD. However, after the treatment no toxicity was detected. Levels of TBARS and PC, CAT activity and the DNA damage index were significantly increased (P<0.05) in Allium cepa L. exposed to untreated AMD when compared to treated AMD and also to negative controls. No significant alteration in the GSH content was observed. In conclusion, the use of calcinated coal mining waste associated with toxicological tests on Allium cepa L. represents an alternative system for the treatment and biomonitoring of these types of environmental contaminants.

This study examined the diagnostic accuracy of selected language sample measures (LSMs) with Persian-speaking children. A pre-accuracy study followed by phase I and II studies are reported. Twenty-four Persian-speaking children, aged 42 to 54 months, with primary language impairment (PLI) were compared to 27 age-matched children without PLI on a set of measures derived from play-based, conversational language samples. Results showed that correlations between age and LSMs were not statistically significant in either group of children. However, a majority of LSMs differentiated children with and without PLI at the group level (phase I), while three of the measures exhibited good diagnostic accuracy at the level of the individual (phase II). We conclude that general LSMs are promising for distinguishing between children with and without PLI. Persian-specific measures are mainly helpful in identifying children without language impairment while their ability to identify children with PLI is poor.

The aim of this study was to evaluate the psychometric properties of the Persian version of the International Consultation on Incontinence Modular Questionnaire for Female Lower Urinary Tract Symptoms (ICIQ-FLUTS) in patients with urinary tract dysfunction. After gaining permission from the International Consultation on Incontinence Modular Questionnaire (ICIQ) advisory board, the English Female Lower Urinary Tract Symptoms (FLUTS) questionnaire was translated into Persian and then translated back into English. One hundred fourteen women with pelvic floor dysfunction were asked to complete the Persian FLUTS and International Consultation on Incontinence Modular Questionnaire Overactive Bladder Questionnaire (ICIQ-OAB). The Persian FLUTS questionnaire was also readministered to 20 patients 2 weeks after their initial visit. Study data were analyzed using SPSS V16.0. To validate the translated questionnaire, we assayed content/face validity, internal consistency/reliability, and construct validity. Internal consistency and test-retest reliability were assessed using Cronbach's alpha and the intraclass correlation coefficient (ICC) respectively. The mean age of the patients was 48.8 years old, 84% were married, and 59% had at least one Caesarean. Except for very few missing data, there is no any ambiguity in the Persian version of the FLUTS questionnaire. The Cronbach's alpha was 0.83, indicating a high internal consistency. Concerning criterion validity, correlation between the Persian FLUTS and the OAB was 0.77 (p < 0.001). The initial testing of the Persian version of the FLUTS questionnaire demonstrates good internal consistency, content validity, and reliability.

Objective: One of the most common global disorders is related to gastrointestinal system. Functional dyspepsia (FD) defined as upper abdominal pain and discomfort in the absence of organic ailments is a prevalent disease without any confirmed medication. The purpose of this study was to find gastric disorders which might be coincidental to FD based on traditional Persian medicine (TPM). Materials and Methods: We searched the main textbooks of TPM including Al-Havi (by Rhazes), Canon of medicine (by Avicenna), ZakhireKhawrazmshahi (by Ismail Jorjani), Moalijat-e Aghili and Makhzan Al-adviya (by Mohammad Hosein AghiliShirazi), and ExirAzam (by Hakim Azam Khan). Also, we searched Pubmed, Scopus, Science Direct, Medline, scientific information database (SID), Iranmedex and Google Scholar from 1980 to 1 August 2014 for dyspepsia, gastrointestinal disease, traditional Persian medicine, and gastric dystemperaments. Results: There is no equivalent term for FD in traditional Persian medicine although similar signs and symptoms are visible in terms like simple cold dystemperament of stomach, indigestion, and digestion debility in TPM sources. Some treatments mentioned in TPM have shown promising results in the current experimental tests. Conclusion: Finding these similarities in complementary and alternative medicine (CAM) textbooks may lead to discovering new remedies for this widespread disease. PMID:27222829

The Brief Assessment of Cognition in Schizophrenia (BACS) is designed for assessment of cognitive function in patients with schizophrenia. Versions of the BACS in English and other languages have been shown to be as sensitive to cognitive dysfunction as a standard test battery, with the advantage of brief administration and scoring time. The present study aimed to test the concurrent validity of the Persian version of the BACS (Persian-BACS). A group of 50 patients with schizophrenia-spectrum disorders and a group of 50 healthy controls received the Persian-BACS in a first session, and in a second session a standard neurocognitive battery. Cronbach's alpha for the Persian-BACS was 0.74. All the Persian-BACS subscales were significantly correlated with the corresponding standard neurocognitive subscales and the Pearson correlation of the composite scores from the two instruments was 0.71. Moreover, a one-factor solution was found that accounted for 67.9% of the variance. Finally, the Persian-BACS demonstrated high ability to discriminate patients with schizophrenia from healthy controls. Good psychometric properties of the Persian-BACS suggest that it is a useful tool for assessing cognition in schizophrenic patients with Persian as their primary language. © 2013 The Authors.

The feeling of abdominal fullness, bloating, and movement of gas in the abdomen is a very uncomfortable sensation termed flatulence. Since flatulence is one of the most common gastrointestinal symptoms that is bothersome to patients, it is important to identify effective methods to resolve this issue. In modern medicine, management of flatulence is often not satisfactory. On the other hand, traditional systems of medicine can be considered good potential sources to find new approaches for preventing and treating flatulence. The aim of this study is to review flatulence treatments from a traditional Persian medicine (TPM) viewpoint. In this study, the reasons for flatulence and methods for its prevention and treatment are reviewed in traditional Persian medicine (TPM) texts and then related with evidence from modern medicine by searching in databases, including PubMed, Scopus, Google Scholar, and IranMedex. From a traditional Persian scholar viewpoint, one of the most important causes of flatulence is an incorrect manner of eating; valuable advice to correct bad eating habits will be illustrated. In addition, traditional practitioners describe some herbs and vegetables as well as herbal compounds that are effective food additives to relieve flatulence. The anti-flatulent effect of most of these herbs has been experimentally verified using modern medicine. Attention to TPM can lead to the identification of new preventive and curative approaches to avoid and treat flatulence. In addition, Persian viewpoints from the medieval era regarding flatulence are historically important.

Persian bamboo shark (Chiloscyllium arabicum) was collected from two sites of the Khozestan province, northern basin of Persian Gulf, with the aim to identify differences in metal concentrations between fishing areas as well as the risk for human health due to consumption of the selected species. We analyzed Zn, Cu, Pb, Hg, Cd and Ni in muscle and liver tissues of specimens from both areas of study using atomic adsorption spectrometry. Statistical elaborations revealed higher bioaccumulation of metals in livers than muscle as well as in the site of worthy of Musa as regards Zn, Pb and Ni than the site of worthy of Darvis, due to the more intensive anthropogenic input. The risk for consumers is low for the most of metals, with the exception of the THQ for Hg, which resulted next to the level of risk with high frequencies of consumption.

2013-01-01

Background Over one hundred different pharmaceutical dosage forms have been recorded in literatures of Traditional Persian Medicine among which nasal forms are considerable. Objectives This study designed to derive the most often applied nasal dosage forms together with those brief clinical administrations. Materials and Methods In the current study remaining pharmaceutical manuscripts of Persia during 9th to 18th century AD have been studied and different dosage forms related to nasal application of herbal medicines and their therapeutic effects were derived. Results By searching through pharmaceutical manuscripts of medieval Persia, different nasal dosage forms involving eleven types related to three main groups are found. These types could be derived from powder, solution or liquid and gaseous forms. Gaseous form were classified into fumigation (Bakhoor), vapor bath (Enkebab), inhalation (Lakhlakheh), aroma agents (Ghalieh) and olfaction or smell (Shomoom). Nasal solutions were as drops (Ghatoor), nasal snuffing drops (Saoot) and liquid snuff formulations (Noshoogh). Powders were as nasal insufflation or snorting agents (Nofookh) and errhine or sternutator medicine (Otoos). Nasal forms were not applied only for local purposes. Rather systemic disorders and specially CNS complications were said to be a target for these dosage forms. Discussion While this novel type of drug delivery is known as a suitable substitute for oral and parenteral administration, it was well accepted and extensively mentioned in Persian medical and pharmaceutical manuscripts and other traditional systems of medicine as well. Accordingly, medieval pharmaceutical standpoints on nasal dosage forms could still be an interesting subject of study. Therefore, the current work can briefly show the pharmaceutical knowledge on nasal formulations in medieval Persia and clarify a part of history of traditional Persian pharmacy. PMID:24624204

History of attitudes toward death: a comparative study between Persian and western cultures.

2016-01-01

In his seminal book on the historical periods of Western attitudes toward death, Philippe Aries describes four consecutive periods through which these attitudes evolved and transformed. According to him, the historical attitudes of Western cultures have passed through four major parts described above: "Tamed Death," One's Own Death," "Thy Death," and "Forbidden Death." This paper, after exploring this concept through the lens of Persian Poetic Wisdom, concludes that he historical attitudes of Persian-speaking people toward death have generally passed through two major periods. The first period is an amalgamation of Aries' "Tamed Death" and "One's Own Death" periods, and the second period is an amalgamation of Aries' "Thy Death" and "Forbidden Death" periods. This paper explores the main differences and similarities of these two historical trends through a comparative review of the consecutive historical periods of attitudes toward death between the Western and Persian civilizations/cultures. Although both civilizations moved through broadly similar stages, some influential contextual factors have been very influential in shaping noteworthy differences between them. The concepts of after-death judgment and redemption/downfall dichotomy and practices like deathbed rituals and their evolution after enlightenment and modernity are almost common between the above two broad traditions. The chronology of events and some aspects of conceptual evolutions (such as the lack of the account of permanent death of nonbelievers in the Persian tradition) and ritualistic practices (such as the status of the tombs of Shiite Imams and the absolute lack of embalming and wake in the Persian/Shiite culture) are among the differences.

STS-45 Earth observation taken aboard Atlantis, Orbiter Vehicle (OV) 104, is of the northern reaches of the Persian Gulf with the sunglint pattern centered on the Saudi Arabian island of Abu Ali. Bright features along the coast are thought to be deposits of oil, released from a terminal offshore of Kuwait during the recent Persian Gulf War. Further up the coast, in Kuwait, the black, oil-soaked desert surrounding the site of the oil well fires is clearly visible. View was taken from an altitude of 160 nautical miles with OV-104 located at 28 degrees north and 52.8 degrees east. During the STS-45 mission, an international survey team focused on oil contamination of the shallow-water habitants in the area north of Abu Ali Island. Crewmembers contacted the NOAA survey vessel, the R/V Mt. Mitchell, several times and photographed water color and sunglint within the study area and throughout the entire Persian Gulf. These photographic data are expected to aid the Persian Gulf researchers in

In this study, we reported the reliability and validity of Bedside version of Persian WAB (P-WAB-1) adapted from Western Aphasia Battery (WAB-R) (1,2). P-WAB-1 is a clinical linguistic measuring tool to determine severity and type of aphasia in brain damaged patients based on Aphasia Quotient (AQ) as a functional measure. For the purposes of a quick clinical screening of aphasia in Persian, we adapted the bedside version of WAB-R to assess the performance of Persian aphasic patients. The data we reported on adaptation, validity and reliability of P-WAB-1 are based on faithful translation and criterion validity ratio (CVR) taken from the expert panel and the performance of 60 consecutive brain damaged patients referred to different university clinics for rehabilitation and 30 healthy subjects as norms and 40 age-matched epileptic patients as the control group. Based on the results of this study, P-WAB-1 has internal consistency (a=0.71) and test-retest reliability (r=.65 P<0.001) and the subtests are sensitive enough to contribute to Aphasia Quotient (AQ) as a functional measure of severity of aphasia in Iranian brain damaged patients. Based on AQ results, our aphasic patients were classified into four distinct groups of severity. P-WAB-1 is the first clinical linguistic test to determine severity of aphasia based on an operational index and can be considered as a valid baseline for screening and diagnosis of aphasia among Persian speaking brain damaged patients. This study is the initial step on adaptation of different versions of WAB-R to measure the severity of aphasia using AQ, LQ and CQ as operational measures and to classify Persian speaking aphasic patients into different types.

Purple blotch, caused by Alternaria porri (Ellis) Cifferi, is a serious disease incurring heavy yield losses in the bulb and seed crop of onion and garlic worldwide. There is an immediate need for identification of effective resistance sources for use in host resistance breeding. A total of 43 Allium genotypes were screened for purple blotch resistance under field conditions. Allium cepa accession 'CBT-Ac77' and cultivar 'Arka Kalyan' were observed to be highly resistant. In vitro inoculation of a selected set of genotypes with A. porri , revealed that 7 days after inoculation was suitable to observe the disease severity. In vitro screening of 43 genotypes for resistance to A. porri revealed two resistant lines. An additional 14 genotypes showed consistent moderate resistance in the field as well as in vitro evaluations. Among the related Allium species, A. schoenoprasum and A. roylei showed the least disease index and can be used for interspecific hybridization with cultivated onion. Differential reaction analysis of three A. porri isolates ( Apo-Chiplima, Apn-Nasik, Apg-Guntur ) in 43 genotypes revealed significant variation among the evaluated Allium species ( P = 0.001). All together, the present study suggest that, the newly identified resistance sources can be used as potential donors for ongoing purple blotch resistance breeding program in India.

“Melancholia” seems to be the oldest term used to describe the manifestations of depression. Throughout the history of medicine, melancholia has been the focus of consideration of many scholars who have provided varying definitions of this disorder and its manifestations. This continual process has resulted in the gradual development of the concept of melancholia over time. Persian scholars were among the scientists who have studied the melancholia and contributed to its concept. One figure, Al-Akhawayni Bukhari (?-983 AD), a Persian physician whose reputation was based on the treatment of patients with mental problems, investigated this disorder. He described Melancholia and explained its clinical manifestations and treatment methods. Al-Akhawayni provided an early classification of the patients suffering from this disorder. Since the medieval Persian concept of melancholia is not well-known, this paper aims to review Al-Akhawayni’s 10th century knowledge on melancholia which can represent the early concept of this disorder in the Near East.

In this study, the phase behavior of sodium caseinate-Persian gum mixtures was investigated. The effect of thermodynamic incompatibility on phase distribution of sodium caseinate fractions as well as the flow behavior and microstructure of the biopolymer mixtures were also studied. The phase diagram clearly demonstrated the dominant effect of Persian gum on the incompatibility of the two biopolymers. SDS-PAGE electrophoresis indicated no selective fractionation of sodium caseinate subunits between equilibrium phases upon de-mixing. The microstructure of mixtures significantly changed depending on their position within the phase diagram. Fitting viscometric data to Cross and Bingham models revealed that the apparent viscosity, relaxation time and shear thinning behavior of the mixtures is greatly influenced by the volume ratio and concentration of the equilibrium phases. There is a strong dependence of the flow behavior of sodium caseinate-Persian gum mixtures on the composition of the equilibrium phases and the corresponding microstructure of the system.

The major components were: dimethyl-trisulfide (16.64%), methyl-propyl-trisulfide (14.21%), dietil-1,2,4-tritiolan (3R,5S-, 3S,5S- and 3R,5R- isomers) (13.71%), methyl-(1-propenyl)-disulfide (13.14%), and methyl-(1-propenyl)-trisulfide (13.02%). The major components of garlic EO were diallyl-trisulfide (33.55%), and diallyl-disulfide (28.05%). The mycelial growth and the STC production were recorded after 7, 14, and 21 d of the A. versicolor growth in Yeast extract sucrose (YES) broth containing different EOs concentrations. Compared to the garlic EO, the onion EO showed a stronger inhibitory effect on the A. versicolor mycelial growth and STC production. After a 21-d incubation of fungi 0.05 and 0.11 μg/mL of onion EO and 0.11 μg/mL of garlic EO completely inhibited the A. versicolor mycelial growth and mycotoxins biosynthesis. The combination of EOs of onion (75%) and garlic (25%) had a synergistic effect on growth inhibition of A. versicolor and STC production. © 2012 Institute of Food Technologists®

Diabetes Mellitus is a common metabolic disorder presenting increased amounts of serum glucose and will cover 5.4% of population by year 2025. Accordingly, this review was performed to gather and discuss the stand points on diagnosis, pathophysiology, non-pharmacological therapy and drug management of diabetes this disorder as described in medieval Persian medicine. To this, reports on diabetes were collected and analyzed from selected medical and pharmaceutical textbooks of Traditional Persian Medicine. A search on databases as Pubmed, Sciencedirect, Scopus and Google scholar was also performed to reconfirm the Anti diabetic activities of reported herbs. The term, Ziabites, was used to describe what is now spoken as diabetes. It was reported that Ziabites, is highly associated with kidney function. Etiologically, Ziabites was characterized as kidney hot or cold dystemperament as well as diffusion of fluid from other organs such as liver and intestines into the kidneys. This disorder was categorized into main types as hot (Ziabites-e-har) and cold (Ziabites-e-barid) as well as sweet urine (Bole-e-shirin). Most medieval cite signs of Ziabites were remarked as unusual and excessive thirst, frequent urination and polydipsia. On the management, life style modification and observing the essential rules of prevention in Persian medicine as well as herbal therapy and special simple manipulations were recommended. Current investigation was done to clarify the knowledge of medieval scientists on diabetes and related interventions. Reported remedies which are based on centuries of experience might be of beneficial for- further studies to the management of diabetes. PMID:24741508

Morningness-eveningness preference is commonly measured by questionnaires such as the Composite Scale of Morningness (CSM). The purpose of this study is to assess the Persian translation of the CSM and explore its psychometric properties. Participants consisted of 288 students at the University of Bojnord, Iran. Of the participants selected, 47.6% were female, 52.4% were male, and all were aged between 18 and 24 (20.09±1.32). Participants were selected using the stratified random sampling method. The scale was translated into Persian using the parallel translation method. SPSS-22 and AMOS-22 were used for analyses. Mean CSM scores were 31.43±6.32 in a range of 14-50. Internal reliability, as measured by Cronbach's α, was 0.790, which fits well with previous studies undertaken in many countries. The factor analysis revealed a two-factor structure based on parallel analysis: one factor was labeled as "morning affect" and the other as "self-assessment/activity planning." Also, the confirmatory factor analysis supported the two-factor model fit. Construct validity was also evaluated by the MEQ with the results showing that correlations were comparable to other studies (r=0.76). Results did not show any significant correlation between age (r=0.041; P=0.487) and the CSM scores. According to the results of the t-test, women and men were not significantly different in terms of the CSM scores (t=-0.264; P=0.792). The Persian version of the CSM is freely available and can be adopted for behavioral research related to sleep and circadian function and also applied to other Persian-speaking populations.

Elbow joint pathologies are highly prevalent in Persian-speaking countries. A reliable low-cost method like an appropriate questionnaire is mandatory for the early diagnosis of elbow joint disorders. Among designed questionnaires, Patient-Rated Elbow Evaluation (PREE) is an accepted commonly used scale evaluating pain and dysfunction of the patients. The aims of the study were to cross-culturally adapt and also to identify the psychometric properties of the Persian PREE. The original version of the PREE was translated and cross-culturally adapted to Persian according to the guidelines by Beaton et al. Seventy-three patients and thirty-nine healthy people were enrolled in the study. Test-retest reliability and internal consistency were evaluated using ICC, Cronbach's alpha, and item-total correlation, respectively. Construct validity was investigated using Disability of Arm, Shoulder, and Hand (DASH) questionnaire and physical component scale of SF-36 (PCS). To determine a cutoff point for discriminating patients from non-patients, receiver operating characteristic curve was plotted. The Persian PREE displayed high internal consistency (Cronbach's alpha = 0.91) and had acceptable ICC values in the subscales and total score (ICC > 0.90). A positive moderate correlation with DASH (r = 0.66, P < 0.001) and a negative moderate correlation with PCS of SF-36 (r = -0.44, P < 0.001) were observed. The cutoff point equal to 13.16 was determined for Persian PREE. The Persian PREE exhibited promising validity and reliability. The findings supported its applicability in clinical situations that were consistent with the original version.

Effects of salep gum at concentrations of 0.5%, 1%, 3%, and 5% (w/w flour basis) and the Persian gum at concentrations of 0.5%, 1%, and 3% (w/w flour basis) and combination of the two gums at concentrations of 0.5% + 0.5%, 0.75% + 0.25%, and 0.25% + 0.75% on rheological properties of the wheat flour dough and quality of Taftoon bread were studied with regard to retardation of staling. Rheological (farinograph and extensograph) characteristics, staling, and organoleptic evaluations were performed on the dough and the resulting Taftoon bread. Statistical results showed that the salep gum at 5% and Persian gum at 3% (w/w flour basis) had a significant effect on the dough properties. Salep and Persian gums when each separately added increased and decreased dough water absorption, respectively. Both hydrocolloids increased the dough resistance to extension and decreased its extensibility. Persian gum shows dual nature in water absorption and some other baking properties. Textural studies revealed that addition of 5% salep gum (w/w flour basis) reduced the bread crumb firmness and delayed the staling process of the Taftoon bread. X-ray diffraction study also confirmed this result.

The aim was to culturally translate and validate the Persian lower extremity functional scale (LEFS) in a heterogeneous sample of outpatients with lower extremity musculoskeletal disorders (n = 304). This is a prospective methodological study. After a standard forward-backward translation, psychometric properties were assessed in terms of test-retest reliability, internal consistency, construct validity, dimensionality, and ceiling or floor effects. The acceptable level of intraclass correlation coefficient >0.70 and Cronbach's alpha coefficient >0.70 was obtained for the Persian LEFS. Correlations between Persian LEFS and Short-Form 36 Health Survey (SF-36) subscales of Physical Health component (rs range = 0.38-0.78) were higher than correlations between Persian LEFS and SF-36 subscales of Mental Health component (rs range = 0.15-0.39). A corrected item--total correlation of >0.40 (Spearman's rho) was obtained for all items of the Persian LEFS. Horn's parallel analysis detected a total of two factors. No ceiling or floor effects were detected for the Persian LEFS. The Persian version of the LEFS is a reliable and valid instrument that can be used to measure functional status in Persian-speaking patients with different musculoskeletal disorders of the lower extremity. Implications for Rehabilitation The Persian lower extremity functional scale (LEFS) is a reliable, internally consistent and valid instrument, with no ceiling or floor effects, to determine functional status of heterogeneous patients with musculoskeletal disorders of the lower extremity. The Persian version of the LEFS can be used in clinical and research settings to measure function in Iranian patients with different musculoskeletal disorders of the lower extremity.

The objective of the study was to summarize the methods for isolating and identifying natural sulfur compounds from Allium ursinum (ramson) and to discuss the active constituents with regard to antifungal action. Using chromatographic techniques, the active constituents were isolated and subsequently identified. Analyses by high-performance liquid chromatography (HPLC) suggested that these compounds were sulfur constituents, with a characteristic absorbance at 250 nm. Gas chromatography-mass spectrometry (GC-MS) analyses allowed the chemical structures of the isolated constituents to be postulated. We adopted the same methods to identify the health-giving profiling of ramsons and the effects are thought to be primarily derived from the presence and breakdown of the alk(en)ylcysteine sulphoxide, alliin and its subsequent breakdown to allicin (sulfur-compounds of ramson) in connection with antifungal action. The aim of the study was the characterization of the chemical composition of ramsons and the testing of the action of the in vitro extracts, on different strains of Candida albicans. The main goal was to highlight the most efficient extracts of Allium ursinum that can provide long-term antifungal activity without remissions. The extracts from Allium ursinum plants, inhibited growth of Candida spp. cells at concentrations ranging from 0.5 to 4.0 mg/mL, while that of adherent cells at concentrations ranging from 1.0 to > 4.0 mg/mL, depending on the yeast and plant species.

The use of the internet as a source of information gathering, self-help and support is becoming increasingly recognized. Parents and professionals of children with hearing impairment have been shown to seek information about different communication approaches online. Cued Speech is a very new approach to Persian speaking pupils. Our aim was to develop a useful website to give related information about Persian Cued Speech to parents and professionals of children with hearing impairment. All Cued Speech websites from different countries that fell within the first ten pages of Google and Yahoo search-engines were assessed. Main subjects and links were studied. All related information was gathered from the websites, textbooks, articles etc. Using a framework that combined several criteria for health-information websites, we developed the Persian Cued Speech website for three distinct audiences (parents, professionals and children). An accurate, complete, accessible and readable resource about Persian Cued Speech for parents and professionals is available now.

To determine cause-specific mortality rates among US troops stationed in the Persian Gulf region and compare them with those of US troops serving elsewhere during Operations Desert Shield and Desert Storm. Retrospective cohort. US men and women on active duty from August 1, 1990, through July 31, 1991. Deaths occurring among all active-duty US military persons during the 1-year study period. Age-adjusted mortality rates among US troops stationed in the Persian Gulf region were compared with rates projected from mortality rates among troops on active duty elsewhere. A total of 1769 active-duty persons died during the study period, 372 in the Persian Gulf region and 1397 elsewhere. Of the 372 deaths in the Persian Gulf region, 147 (39.5%) occurred as a direct result of combat during the war, 194 (52.2%) resulted from injuries not incurred in battle, and 30 (8%) resulted from illness. Twenty-three of the deaths due to illness were considered unexpected or cardiovascular deaths. Based on age-adjusted mortality rates observed among US troops on active duty outside the Persian Gulf region, 165 deaths from unintentional injury and 32 deaths from illness (20 of which were unexpected or cardiovascular) would have been anticipated among Persian Gulf troops. Except for deaths from unintentional injury, US troops in the Persian Gulf region did not experience significantly higher mortality rates than US troops serving elsewhere. There were no clusters of unexplained deaths. The number and circumstances of nonbattle deaths among Persian Gulf troops were typical for the US military population.

To translate and cross-culturally adapt the Functional Independence Measure (FIM) into the Persian language and to test the reliability and validity of the Persian FIM (PFIM) in patients with stroke. In this cross-sectional study carried out in an outpatient stroke rehabilitation center, 40 patients with stroke (mean age 60 years) were participated. A standard forward-backward translation method and expert panel validation was followed to develop the PFIM. Two experienced occupational therapists (OTs) assessed the patients independently in all items of the PFIM in a single session for inter-rater reliability. One of the OTs reassessed the patients after 1 week for intra-rater reliability. There were no floor or ceiling effects for the PFIM. Excellent inter-rater and intra-rater reliability was noted for the PFIM total score, motor and cognitive subscales (ICC(agreement)0.88-0.98). According to the Bland-Altman agreement analysis, there was no systematic bias between raters and within raters. The internal consistency of the PFIM was with Cronbach's alpha from 0.70 to 0.96. The principal component analysis with varimax rotation indicated a three-factor structure: (1) self-care and mobility; (2) sphincter control and (3) cognitive that jointly accounted for 74.8% of the total variance. Construct validity was supported by a significant Pearson correlation between the PFIM and the Persian Barthel Index (r = 0.95; p < 0.001). The PFIM is a highly reliable and valid instrument for measuring functional status of Persian patients with stroke. The Functional Independence Measure (FIM) is an outcome measure for disability based on the International Classification of Functioning, Disability and Health (ICF). The FIM was cross-culturally adapted and validated into Persian language. The Persian version of the FIM (PFIM) is reliable and valid for assessing functional status of patients with stroke. The PFIM can be used in Persian speaking countries to assess the

Carpal tunnel syndrome (CTS) is recognized as the most common type of neuropathies. Questionnaires are the method of choice for evaluating patients with CTS. Boston Carpal Tunnel Syndrome (BCTS) is one of the most famous questionnaires that evaluate the functional and symptomatic aspects of CTS. This study was performed to evaluate the validity and reliability of the Persian version of BCTS questionnaire. First, both parts of the original questionnaire (Symptom Severity Scale and Functional Status Scale) were translated into Persian by two expert translators. The translated questionnaire was revised after merging and confirmed by an orthopedic hand surgeon. The confirmed questionnaire was interpreted back into the original language (English) to check for any possible content inequality between the original questionnaire and its final translated version. The final Persian questionnaire was answered by 10 patients suffering from CTS to elucidate its comprehensibility; afterwards, it was filled by 142 participants along with the Persian version of the Quick-DASH questionnaire. After 2 to 6 days, the translated questionnaire was refilled by some of the previous patients who had not received any substantial medical treatment during that period. Among all 142 patients, 13.4 % were male and 86.6 % were female. The reliability of the questionnaire was tested using Cronbach's alpha and Intraclass correlation coefficient (ICC). Cronbach's alpha was 0.859 for symptom severity scale (SSS) and 0.878 for functional status scale (FSS). Also, ICCs were calculated as 0.538 for SSS and 0.773 for FSS. In addition, construct validity of SSS and FSS against QuickDASH were 0.641 and 0.701, respectively. Based on our results, the Persian version of the BCTQ is valid and reliable.

Purple blotch, caused by Alternaria porri (Ellis) Cifferi, is a serious disease incurring heavy yield losses in the bulb and seed crop of onion and garlic worldwide. There is an immediate need for identification of effective resistance sources for use in host resistance breeding. A total of 43 Allium genotypes were screened for purple blotch resistance under field conditions. Allium cepa accession ‘CBT-Ac77’ and cultivar ‘Arka Kalyan’ were observed to be highly resistant. In vitro inoculation of a selected set of genotypes with A. porri, revealed that 7 days after inoculation was suitable to observe the disease severity. In vitro screening of 43 genotypes for resistance to A. porri revealed two resistant lines. An additional 14 genotypes showed consistent moderate resistance in the field as well as in vitro evaluations. Among the related Allium species, A. schoenoprasum and A. roylei showed the least disease index and can be used for interspecific hybridization with cultivated onion. Differential reaction analysis of three A. porri isolates (Apo-Chiplima, Apn-Nasik, Apg-Guntur) in 43 genotypes revealed significant variation among the evaluated Allium species (P = 0.001). All together, the present study suggest that, the newly identified resistance sources can be used as potential donors for ongoing purple blotch resistance breeding program in India. PMID:27904458

Introduction: Nowadays, anyone with any level of Internet knowledge can act as producer and distributor of information. It differs from most traditional media of information transmission, lack of information control and lack of quality management to contents. This leads to quality of health information on the internet is doubtful. The object of this study is guidance patients to select valid mental disorders and determine the quality of Persian mental disorders websites. Methods: The sample of this study comprised 29 Persian mental disorders websites that were chosen by searching the Google, Yahoo and AltaVista search engines for the Persian equivalents of the three concepts “depression,” “anxiety,” and “obsession”. website was created by individuals or organizations. Data collection was performed with the WebMedQual checklist. Websites was assessed based on indicators as content, authority of source, design, accessibility and availability, links, user support, and confidentiality and privacy (Maximum score for any website was 83, mean score 41.5 and minimum score was 0). Collected data analyzed by one sample T- test in SPSS 20. Findings presented by Mean score and optimal score. Results: Based on the WebMedQual scale the mean score of Persian mental disorders websites in sex constructs including “content” (7.02±2.10), “authority of source” (4.71±1.96),”accessibility and availability” (2.19±0.47), “links” (1.45±0.97), “user support” (4.28±1.33), and”confidentiality and privacy” (2.81±2.81) are poor and below average, but the score for the “design” (9.17± 1.59) is above average. The best website of mental disorders was that of the “IranianPsychological Association”. Conclusions: According to the results, only one website obtained the average score, so the quality of Persian mental disorders websites is low. Therefore, it is essential for users to criticize websites’ content and not trust them before evaluating

Generation of Wind Waves in the Persian Gulf: A Numerical Investigation

NASA Astrophysics Data System (ADS)

Liao, Y.; Kaihatu, J. M.

2010-12-01

The Persian Gulf is a long shallow basin located between the Arabian Peninsula and Iran. Wind-wave generation processes in the region are often affected by the shamal, a strong wind caused by the passage of cold fronts over the mountains of Turkey and Kurdistan. This can set up sudden energetic wind seas, hampering marine traffic. It is not immediately clear whether present wind-wave models can predict this intense, short-term growth and evolution under these conditions. Furthermore, few wave measurements or models studies have been performed in this area. In advance of a wind-wave generation experiment to be conducted off the Qatar coast, we performed a climatological study of the wind wave environment in the Persian Gulf. Using the SWAN wave model as a baseline of the state of the art, five years (2004-2008)of wind field model hindcasts from COAMPS are used as forcing.To investigate the sensitivity of the results to bathymetry, the climatological analysis was run twice more, with refraction or wave breaking deactivated, in turn. The results do not show significant differences with and without refraction, which implies the wind-wave process in Persian Gulf is less dominated by the variation of bathymetry. However the results show that a large amount of wave is dissipated by wave breaking. Wide, flat and shallow bathymetry in Persian Gulf results in a long-fetch scenario, particularly for waves arriving from the northwest. It implies that long period wind-generated waves can be fully generated in this region. Wave height is therefore fully grown by the long-fetch condition, so as to lead in higher possibility of wave breaking and energy dissipation.

The purpose of the present study was to translate and to cross-culturally adapt the Cumberland Ankle Instability Tool (CAIT) into Persian language and to evaluate its psychometric properties. The International Quality of Life Assessment process was pursued to translate CAIT into Persian. Two groups of Persian-speaking individuals, 105 participants with a history of ankle sprain and 30 participants with no history of ankle sprain, were asked to fill out Persian version of CAIT (CAIT-P), Foot and Ankle Ability Measure (FAAM), and Visual Analog Scale (VAS). Data obtained from the first administration of CAIT were used to evaluate floor and ceiling effects, internal consistency, dimensionality, and criterion validity. To determine the test-retest reliability, 45 individuals re-filled CAIT 5-7 days after the first session. Cronbach's alpha was over the cutoff point of 0.70 for both ankles and in both groups. The intra-class correlation coefficient was high for right (0.95) and left (0.91) ankles. There was a strong correlation between each item and the total score of the CAIT-P. Although the CAIT-P had strong correlation with VAS, its correlation with both subscales of FAAM was moderate. The CAIT-P has good validity and reliability and it can be used by clinicians and researchers for identification and investigation of functional ankle instability. Implications for Rehabilitation Chronic ankle instability is one of the most common consequences of acute ankle sprain. Cumberland Ankle Instability Tool is an acceptable measure to determine functional ankle instability and its severity. The Persian version of Cumberland Ankle Instability Tool is a valid and reliable tool for clinical and research purpose in Persian-speaking individuals.

Plants from the Allium genus are valued worldwide for culinary flavor and medicinal attributes. In this study, 16 cultigens of bunching onion (Allium fistulosum L.) were grown in a glasshouse under filtered UV radiation (control) or supplemental UV-B radiation [7.0 μmol·m−2 ·s−2 (2.68 W·m−2)] to determine impacts on growth, physiological parameters, and nutritional quality. Supplemental UV-B radiation influenced shoot tissue carotenoid concentrations in some, but not all, of the bunching onions. Xanthophyll carotenoid pigments lutein and β-carotene and chlorophylls a and b in shoot tissues differed between UV-B radiation treatments and among cultigens. Cultigen “Pesoenyj” responded to supplemental UV-B radiation with increases in the ratio of zeaxanthin + antheraxanthin to zeaxanthin + antheraxanthin + violaxanthin, which may indicate a flux in the xanthophyll carotenoids towards deepoxydation, commonly found under high irradiance stress. Increases in carotenoid concentrations would be expected to increase crop nutritional values. PMID:23606817

Allium flavum L. and Allium melanantherum Panč. are wild growing plants used in traditional diet in Balkan region. While chemical composition and some biological activities of A. flavum have been reported, A. melanantherum, as an endemic in the Balkan Peninsula, has never been comprehensively examined. After chemical characterization of A. melanantherum, we examined the protective effect of methanol extracts of both species against t-butyl hydro-peroxide (t-BOOH)-induced DNA damage and mutagenesis. The bacterial reverse mutation assay was performed on Escherichia coli WP2 oxyR strain. DNA damage was monitored in human fetal lung fibroblasts (MRC-5) with alkaline comet assay. Obtained results indicated that extracts reduced t-BOOH-induced DNA damage up to 70 and 72% for A. flavum and A. melanantherum extract, respectively, and showed no effect on t-BOOH-induced mutagenesis. Since the results indicated modulatory effect on cell-mediated antioxidative defense, the effect of extracts on total protein content, and superoxide dismutase (SOD) and catalase (CAT) amounts and activities were monitored. Both extracts increased total protein content, while the increase of enzyme amount and activity was obtained only with A. melanantherum extract and restricted to CAT. The activity of CuZnSOD family was not affected, while SOD1 and SOD2 amounts were significantly decreased, indicating potential involvement of extracellular CuZnSOD. Obtained results strongly support the traditional use of A. flavum and A. melanantherum in nutrition and recommend them for further study.

Hydropower offers a reliable source of electricity in several countries, and Brazil supplies its energy needs almost entirely through hydropower plants. Nevertheless, hydropower plants comprise large buildings and water reservoirs and dams, resulting in huge ecological disruptions. Here, we analyzed the impact of four hydropower reservoirs construction in metals and pesticides incidence and the cytotoxic and genotoxic potential of sediment elutriate of rivers from southern Brazil. Our analyses have evidenced the elevated incidence of different metals (lead, iron, cadmium, and chrome) and pesticides (methyl parathion, atrazine, and 2,4-dichlorophenoxyacetic acid). We showed that Allium cepa exposed to sediment elutriates did not change the seed germination rate and mitotic index. However, roots from Allium cepa exposed to reservoirs sediment elutriates showed increased occurrence of chromosomal aberrations and nuclear abnormalities. Therefore, the results obtained in our study indicate that sediment from reservoirs present elevated concentration of metals and pesticides and a significant genotoxic potential. Taken together, our data support that hydropower reservoirs represent an environmental scenario that could impact surrounding wildlife and population.

The extraordinary delay of the daily variation of absorption and electron density observed in the ionospheric D region above the Persian Gulf in 1976 observed from the research vessel 'Akademik Kurchatov' may be a consequence of air pollution by oil production by-products. It is suggested that the Gulf war might also have caused a lower ozone abundance in that region.

Chronic heart failure (CHF) is a common burdensome health problem worldwide. Self-care improves outcomes in patients with CHF. The Self-care of Heart Failure Index (SCHFI) is a well-known scale for assessing self-care. A reliable, valid, and culturally acceptable instrument is needed to develop and test self-care interventions in Iran. We sought to translate and validate the Persian version of SCHFI v 6.2 (pSCHFI). We translated the SCHFI into Persian (pSCHFI) using standardized methods. The reliability was evaluated by assessing Cronbach's α coefficient. Expert opinion, discussion with patients, and confirmatory factor analysis were used to assess face validity, content validity, and construct validity, respectively. The analysis, using 184 participants, showed acceptable internal consistency and construct validity for the 3 subscales of pSCHFI-self-care maintenance, self-care management, and self-care self-confidence. The pSCHFI is a valid instrument with an acceptable reliability for evaluating self-care in Persian patients with heart failure.

Do Persian Native Speakers Prosodically Mark Wh-in-situ Questions?

2018-02-01

It has been shown that prosody contributes to the contrast between declarativity and interrogativity, notably in interrogative utterances lacking lexico-syntactic features of interrogativity. Accordingly, it may be proposed that prosody plays a role in marking wh-in-situ questions in which the interrogativity feature (the wh-phrase) does not move to sentence-initial position, as, for example, in Persian. This paper examines whether prosody distinguishes Persian wh-in-situ questions from declaratives in the absence of the interrogativity feature in the sentence-initial position. To answer this question, a production experiment was designed in which wh-questions and declaratives were elicited from Persian native speakers. On the basis of the results of previous studies, we hypothesize that prosodic features mark wh-in-situ questions as opposed to declaratives at both the local (pre- and post-wh part) and global level (complete sentence). The results of the current study confirm our hypothesis that prosodic correlates mark the pre-wh part as well as the complete sentence in wh-in-situ questions. The results support theoretical concepts such as the frequency code, the universal dichotomous association between relaxation and declarativity on the one hand and tension and interrogativity on the other, the relation between prosody and pragmatics, and the relation between prosody and encoding and decoding of sentence type.

To describe the normal ultrasonographic biometry of the Persian cat's eyes using B-mode ultrasonography. In a cross-sectional study, 20 healthy Persian cats with no history of previous ophthalmic disease were examined. Ocular biometry of the left and right eyes was measured using B-mode ultrasonography. Comparison of the average measurements between left and right eyes and between vertical and horizontal planes was performed using paired-sample t test. Correlation of ocular parameters with sex, age, head circumference and eye colour was evaluated. Mean ± standard deviation (SD) measurements of the ocular structures of anterior chamber, lens thickness, vitreous chamber and anterior to posterior dimension of the globe in 40 eyes were 4.1 ± 0.7, 7.7 ± 0.5, 8.2 ± 0.4 and 20.7 ± 1.0 mm, respectively. No significant difference was found between the ocular biometry of the left and right eyes or the horizontal and vertical planes. Of the ocular parameters, the following had a significant positive correlation with head circumference: axial globe length, anterior chamber and lens thickness. The vitreous body had a positive correlation with age. Regarding the breed predisposition of Persian cats to ocular problems, the present study provides baseline information for further clinical investigations of ocular abnormalities using B-mode ultrasonography. © 2014 Australian Veterinary Association.

Dementia is a chronic neurodegenerative disease causing progressive and gradual impairment of different brain's cognitive functions. The prevalence of dementia is about 3 to 7% in different parts of the world. The aim of this study was to determine the etiologies of dementia according to the Traditional Persian Medicine scientists' viewpoint and introduce their recommended herbal remedies for this disease. The authors explored six main Traditional Persian Medicine textbooks for the disease of dementia, its etiologies and related recommended herbal treatments. Two main keywords of "Lisarghes" and" Nesyan" were searched for this purpose. Medical databases, including PubMed, Scopus, Google Scholar, and Science Direct were searched for related articles published between 1966 and 2016 to review the pharmacological components and active ingredients of suggested herbal medicines. According to the Traditional Persian Medicine, dementia is resulted from brain dystemperament, a condition caused by cold and moist or cold and dry tempers. To treat this disease, Traditional Persian scientists recommended various herbal remedies. Current studies have demonstrated that some of these medicinal plants have beneficial effects for the aforementioned disease, including acetyl cholinesterase inhibitory function, neuroprotective effects, and memory enhancing role. The Traditional Persian Medicine literature suggested different herbal remedies for treating dementia. Modern studies support the usefulness of some of these medicines. However, the effect of a large number of these remedies has remained unexamined, a matter which needs to be investigated in future researches.

Traditional Persian Medicine (TPM) was the prevailing practice of medicine in the Eurasia region up through the 18th century, a practice of medicine stemming back to Hippocrates and to the 5000 year old civilization of the region. It is a school of medicine which touches on many a delicate points which may seem unimaginable within the realm of modern allopathic medicine. This practice of ancient medicine besides shedding light on various possible theoretical modern day disorders serves as a vast resource for therapeutics. In this paper, we present study of the manuscripts of this ancient medical practice in search of symptom presentations coinciding with presentation of multiple sclerosis (MS). This paper represents a comprehensive search through TPM texts and manuscripts with the intention to seek possible clues on MS from potentially valuable age-old resources. We predominantly focused our search on the works of five eminent physicians of Medieval Persia: Avicenna (980-1037 AD), Haly Abbas (949-982 AD), Rhazes (865-925 AD), Averroes (1126-1198 AD) and Jorjani (1042-1137 AD). In this paper, the authors attempt a theory and conclude with high probability that a conjunction of a series of signs, symptoms found in TPM texts under the terms khadar, isterkha and falej form the symptoms and the disease pattern of modern day MS. This theory draws upon existent similarities in terms of disease pathology, disease patterns and predisposing factors seen between MS and the related morbidities within Persian Medicine. We recommend further examinations of such potentially valuable long-standing resources, examining the diagnoses and treatments as set forth by Persian Medicine through international collaboration within the global scientific community.

To determine the measurement properties of the Persian language version of the Graves orbitopathy quality of life questionnaire (GO-QOL). Following a systematic translation and cultural adaptation process, 141 consecutive unselected thyroid eye disease (TED) patients answered the Persian GO-QOL and underwent complete ophthalmic examination. The questionnaire was again completed by 60 patients on the second visit, 2-4 weeks later. Construct validity (cross-cultural validity, structural validity and hypotheses testing), reliability (internal consistency and test-retest reliability), and floor and ceiling effects of the Persian version of the GO-QOL were evaluated. Furthermore, Rasch analysis was used to assess its psychometric properties. Cross-cultural validity was established by back-translation techniques, committee review and pretesting techniques. Bi-dimensionality of the questionnaire was confirmed by factor analysis. Construct validity was also supported through confirmation of 6 out of 8 predefined hypotheses. Cronbach's α and intraclass correlation coefficient (ICC) were 0.650 and 0.859 for visual functioning and 0.875 and 0.896 for appearance subscale, respectively. Mean quality of life (QOL) scores for visual functioning and appearance were 78.18 (standard deviation, SD, 21.57) and 56.25 (SD 26.87), respectively. Person reliabilities from the Rasch rating scale model for both visual functioning and appearance revealed an acceptable internal consistency for the Persian GO-QOL. The Persian GO-QOL questionnaire is a valid and reliable tool with good psychometric properties in evaluation of Persian-speaking patients with TED. Applying Rasch analysis to future versions of the GO-QOL is recommended in order to perform tests for linearity between the estimated item measures in different versions.

In this study, we aimed to translate and test the validity and reliablity of the Persian version of the Manchester-Oxford Foot Questionnaire in foot and ankle patients. We translated the Manchester-Oxford Foot Questionnaire to Persian language according to the accepted guidelines, then assessed the psychometric properties including the validity and reliability on 308 patients with long-standing foot and ankle problems. To test the reliability, we calculated the intra-class correlation coefficient (ICC) for test-retest reliability and measured Cronbach's alpha to test the internal consistency. To test the construct validity of the Manchester-Oxford Foot Questionnaire we also administered the Short-Form 36 to patients. Construct validity was supported by significant correlation with SF36 subscales except for pain subscale of the persian MOXFQ with mental health of the SF36 (r=0.207). Intraclass correlation coefficient was 0.79 for the total MOXFQ and ranged from 0.83 to 0.89 for the three subscales. Cronbach's alpha for pain, walking/standing, and social interaction was 0.86, 0.88, and 0.89, respectively, and was 0.79 for the total MOXFQ showing good internal consistency in each domain. The Persian Manchester-Oxford Foot Questionnaire health scoring system is a valid and reliable patient-reported instrument for foot and ankle problems. Copyright © 2015. Published by Elsevier Ltd.

Osteoarthritis of the knee is the most common chronic joint disease that involves middle aged and elderly persons. There are different clinical instruments to quantify the health status of patients with knee osteoarthritis and one example is the WOMAC score that has been translated and adapted into different languages. The purpose of this study was cultural adaptation, validation and reliability testing of the Persian version of the WOMAC index in Iranians with knee osteoarthritis. We translated the original WOMAC questionnaire into Persian by the forward and backward technique, and then its psychometric study was done on 169 native Persian speaking patients with knee degenerative joint disease. Mean age of patients was 53.9 years. The SF-36 and KOOS were used to assess construct validity. Reliability testing resulted in a Cronbach's alpha of 0.917, showing the internal consistency of the questionnaire to be a reliable tool. Inter-correlation matrix among different scales of the Persian WOMAC index yielded a highly significant correlation between all subscales including stiffness, pain, and physical function. In terms of validity, Pearson`s correlation coefficient was significant between three domains of the WOMAC with PF, RP, BP, GH, VT, and PCS dimensions of the SF-36 health survey (P<0.005) and KOOS (P<0.0001) . The Persian WOMAC index is a valid and reliable patient- reported clinical instrument for knee osteoarthritis.

In the present era, thesauri as tools in indexing play an effective role in integrating retrieval preventing fragmentation as well as a multiplicity of terminologies and also in providing information content of documents. This study aimed to investigate the keywords of articles indexed in IranMedex in terms of origin, structure and indexing situation and their Compliance with the Persian Medical Thesaurus and Medical Subject Headings (MeSH). This study is an applied research, and a survey has been conducted. Statistical population includes 32,850 Persian articles which are indexed in the IranMedex during the years 1385-1391. 379 cases were selected as sample of the study. Data collection was done using a checklist. In analyzing the findings, the SPSS Software were used. Although there was no significant difference in terms of indexing origin between the proportion of different types of the Persian and English keywords of articles indexed in the IranMedex, the compliance rates of the Persian and English keywords with the Persian medical thesaurus and MeSH were different in different years. In the meantime, the structure of keywords is leaning more towards phrase structure, and a single word structure and the majority of keywords are selected from the titles and abstracts. The authors' familiarity with the thesauri and controlled tools causes homogeneity in assigning keywords and also provides more precise, faster, and easier retrieval of the keywords. It's suggested that a mixture of natural and control languages to be used in this database in order to reach more comprehensive results.

A clinical outcome tool is needed for the assessment of young athletes with low back pain. To translate and culturally adapt the Micheli functional scale (MFS), a self-report questionnaire developed to evaluate young athletes with low back pain (LBP) into Persian language and examine the reliability and validity of the Persian MFS (PMFS). A cross-sectional study was conducted to assess the psychometric properties of the PMFS. The PMFS was cross-culturally adapted into Persian language adopting forward/backward translation, expert panel review, and pre-testing. The PMFS was administered to young athletes with and without LBP. Main outcome measures were Persian MFS, Persian functional rating Index (PFRI), and visual analogue scale (VAS). A sample of 100 young athletes with LBP with a mean age of 16.5 ± 2.5 years participated. Fifty young athletes without LBP completed the PMFS. There was no missing responses and floor or ceiling effects. There was a significant difference for the total PMFS scores between young athletes with and without LBP. A significant correlation was found between the total PMFS score and the VAS (r = 0.92) or the PFRI (r = 0.82; P < 0.001). A high internal consistency reliability (Cronbach α = 0.73), and excellent test-retest reliability (ICCagreement = 0.99, P < 0.001) were demonstrated for the PMFS. Factor analysis indicated a single-factor model for PMFS scores. The Persian MFS is valid and reliable for use in Persian-speaking young athletes with LBP.

The Persian Gulf and the Gulf of Oman locate at the northwest of the Arabian Sea, with the total area more than 50,0000 km2. The Persian Gulf is a semi-enclosed subtropical sea with high water temperature, extremely high salinity, and an average depth of 50 meters. By the Strait of Hormuz, the Persian Gulf is connected to the Gulf of Oman which is significantly affected by the monsoonal winds and by water exchange between the Arabian Sea and the Persian Gulf. Algal blooms occurred frequently in the Persian Gulf and the Gulf of Oman, and some of them are harmful algal blooms which may lead to massive fish death and thereby serious economic loss. Due to the widely spatial coverage and temporal variation, it is difficult to monitoring the dynamic of the algal bloom based on in situ measurement. In this study, we used the remote sensing data from the Moderate Resolution Imaging Spectroradiometer (MODIS) onboard the Aqua satellite to investigate a massive algal bloom event in the Persian Gulf and the Gulf of Oman during 2008-2009. The time series of MODIS-derived chlorophyll concentration (Chl-a) indicated that the bloom event with high Chl-a concentration ( 60 percent higher than corresponding climatological data) appeared to lasting more than 8 months from autumn of 2008 to spring of 2009. In addition, the bloom was widespread from the Persian Gulf to the Gulf of Oman and neighboring open ocean. The MODIS-derived net primary production (NPP) collected from MODIS showed the same trend with Chl-a. Multiple forces including upwelling, dust deposition was taken into account to elucidate the mechanisms for the long-lasting algal bloom. The time series chlorophyll concentration of the Persian Gulf emerges a significant seasonal pattern with maximum concentrations seen during the winter time and lowest during the summer. It also indicated slight disturbances occurred in June (May/July) and December (November/ January) in some years. The sea surface temperature and water

Background: Vertigo Symptom Scale (VSS) is a proper instrument for assessing the patient status, clarifying the symptoms, and examining the relative impact of the vertigo and anxiety on reported handicap. Our aim is the translation and cross-cultural adaptation of the VSS into Persian language (VSS-P) and investigating its validity and reliability in patients with peripheral vestibular disorders. Materials and Methods: VSS was translated into Persian. Cross-cultural adaptation was carried out on 101 patients with peripheral vestibular disorders and 34 participants with no history of vertigo. They completed the Persian versions of VSS, dizziness handicap inventory (DHI), and Beck anxiety inventory (BAI). Internal, discriminant, and convergent validities, internal consistency, and test-retest reliability were determined. Results: The VSS-P showed good face validity. Internal validity was confirmed and demonstrated the presence of two vertigo (VSS-VER) and autonomic-anxiety (VSS-AA) subscales. Significant difference between the median scores for patient and healthy groups was reported in discriminate validity (P <0.001). Convergent validity revealed high correlation between both BAI and DHI with VSS-P. There was a high test-retest reliability; with intraclass correlation coefficient of 0.89, 0.86, and 0.91 for VSS-AA, VER, and VSS-P, respectively. The internal consistency was good with Cronbach's alpha 0.90 for VER subscale, 0.86 for VSS-AA subscale, and 0.92 for the overall VSS-P. Conclusion: The Persian version of the VSS could be used clinically as a valid and reliable tool. Thus, it is a key instrument to focus on the symptoms associated with dizziness. PMID:28616045

VSS was translated into Persian. Cross-cultural adaptation was carried out on 101 patients with peripheral vestibular disorders and 34 participants with no history of vertigo. They completed the Persian versions of VSS, dizziness handicap inventory (DHI), and Beck anxiety inventory (BAI). Internal, discriminant, and convergent validities, internal consistency, and test-retest reliability were determined. The VSS-P showed good face validity. Internal validity was confirmed and demonstrated the presence of two vertigo (VSS-VER) and autonomic-anxiety (VSS-AA) subscales. Significant difference between the median scores for patient and healthy groups was reported in discriminate validity ( P <0.001). Convergent validity revealed high correlation between both BAI and DHI with VSS-P. There was a high test-retest reliability; with intraclass correlation coefficient of 0.89, 0.86, and 0.91 for VSS-AA, VER, and VSS-P, respectively. The internal consistency was good with Cronbach's alpha 0.90 for VER subscale, 0.86 for VSS-AA subscale, and 0.92 for the overall VSS-P. The Persian version of the VSS could be used clinically as a valid and reliable tool. Thus, it is a key instrument to focus on the symptoms associated with dizziness.

An adult learning to speak a foreign language normally retains an "accent" which may affect the intelligibility of certain sounds, but more often simply conveys the fact that the speaker is a non-native speaker. Various scholars have experimented and discussed the elements involved in a foreign accent. However, in Iran very few researchers have attempted to verify scientifically what are the phonetic and phonological aspects of an "accent." This author tried to determine whether or not a selected group of words, emphasizing stop voicing, produced by native speakers of Persian had significant phonetic and phonemic differences from those achieved by the American students. Subjects for the experiments were three groups of students, one Iranian, two American. A contrastive analysis of the Persian and the English stop consonants was made. An identical measurement test for all three groups was administered. Utilized was a Kay Sona-graph for acoustic analysis, and all spoken data from the Iranian group were compared with those of the American groups. An examination of acoustic correlates of Tehran stops produced by American students shows that the phonetically different but similar feature of /voice/ found in Tehran, Persian and English stops is intuitive to the Americans, and that the language learner cannot readily disassociate a phonological feature from habits of articulation. The results of this research support using the phonetic method for adult learners who want to improve their pronunciation ability. Further research and experimentation is necessary on the effect of the suprasegmental elements on a foreign accent and the most effective teaching materials and methods and to explore other possible techniques in the teaching process.

To test the psychometric properties of the Persian version of Zarit Burden Interview (ZBI-12) in the Iranian population. After translating and cultural adaptation of the questionnaire into Persian, 100 caregiver spouses of Iran- Iraq war (1980-88) veterans with chronic spinal cord injury who live in the city of Mashhad, Iran, invited to participate in the study. The Persian version of ZBI-12 accompanied with the Persian SF-36 was completed by the caregivers to test validity of the Persian ZBI-12.A Pearson`s correlation coefficient was calculated for validity testing. In order to assess reliability of the Persian ZBI-12, we administered the ZBI-12 randomly in 48 caregiver spouses again 3 days later. Generally, the internal consistency of the questionnaire was found to be strong (Cronbach's alpha 0.77). Intercorrelation matrix between the different domains of ZBI-12 at test-retest was 0.78. The results revealed that majority of questions the Persian ZBI_12 have a significant correlation to each other. In terms of validity, our results showed that there is significant correlations between some domains of the Persian version the Short Form Health Survey -36 with the Persian Zarit Burden Interview such as Q1 with Role Physical (P=0.03),General Health (P=0.034),Social Functional (0.037), Mental Health (0.023) and Q3 with Physical Function (P=0.001),Viltality (0.002), Socil Function (0.001). Our findings suggest that the Zarit Burden Interview Persian version is both a valid and reliable instrument for measuring the burden of caregivers of individuals with chronic spinal cord injury.

Xiebai is an edible Chinese herb with various health and therapeutic benefits. To evaluate its nutritional and health values, the free amino acids and derivatives of its two botanical origins (i.e., Allium chinense G. Don and Allium macrostemon Bunge) were isolated using a solvent extraction method and analyzed using automatic amino acid analysis and ultra-performance liquid chromatography-quadrupole-time of flight (UPLC-Q-TOF) mass spectrometry. Our data show that both plants contain abundant free amino acids, and the amount of total free amino acids in A. chinense G. Don is higher than that in A. macrostemon Bunge. The free amino acid compositions in the two plants are qualitatively similar, including nineteen proteinogenic and four non-proteinogenic amino acids. The identified proteinogenic amino acids include eight essential amino acids and five semi-essential amino acids. The sum of essential and semi-essential amino acids accounts for 64.9% and 69.7% of the total free amino acids of the two plants, respectively. The principal amino acids of both plants, from highest concentration to lowest concentration, are arginine, glutamine, glutamic acid, asparagine and serine. A. chinense G. Don is also rich in citrulline and lysine. In addition, two amino acid derivatives were identified from the two plants, i.e., the proline analog N‑methyl‑proline and the dipeptide H-Glu-Tyr-OH. For the first time, the presence of N‑methyl‑proline in the plants of the Allium genus and the presence of H-Glu-Tyr-OH in unprocessed food sources are reported. The influences of the identified substances on the flavor, nutrition and health values of Xiebai are discussed. Copyright © 2018 Elsevier Ltd. All rights reserved.

Pesticides are a group of chemical substances which are widely used to improve agricultural production. However, these substances could be persistent in soil and water, accumulative in sediment or bio-accumulative in biota depending on their solubility, leading to different types of environmental pollution. The present study was done to assess the impact of pesticides-mancozeb and chlorpyrifos, via morphological and physiological parameters using Allium cepa test system. Phytotoxic effects of pesticides were examined via germination percentage, survival percentage, root and shoot length, root shoot length ratio, seedling vigor index, percentage of phytotoxicity and tolerance index. Oxidative stress on Allium seedlings caused by pesticides was also assessed by investigating the activity of antioxidative enzymes viz. catalase, peroxidase and superoxide dismutase. Correlation was worked out between morphological parameters and antioxidative enzymes to bring out the alliance between them. Mancozeb and chlorpyrifos concentrations were significantly and positively correlated with the activity of antioxidative enzymes and negatively correlated with morphological parameters. Significant positive correlation between various morphological parameters showed their interdependency. However, negative correlation was obtained between activity of antioxidative enzymes and morphological parameters. The enzymes however, showed positive correlation with each other. Based on our result we can conclude that all morphological parameters were adversely affected by the two pesticides as reflected by phytotoxicity in Allium . Their negative correlation with activity of antioxidative enzymes indicates that upregulation of antioxidative enzymes is not sufficient to overcome the toxic effect, thereby signifying the threat being caused by the regular use of these pesticides.

Plants produce and emit important volatile organic compounds (VOCs), which have an essential role in biotic and abiotic stress responses and in plant-plant and plant-insect interactions. In order to study the bouquets from plants qualitatively and quantitatively, a comprehensive, analytical method yielding reproducible results is required. We applied in-tube extraction (ITEX) and solid-phase microextraction (SPME) for studying the emissions of Allium plants. The collected HS samples were analyzed by gas chromatography-time-of-flight-mass spectrometry (GC-TOF-MS), and the results were subjected to multivariate analysis. In case of ITEX-method Allium cultivars released more than 300 VOCs, out of which we provisionally identified 50 volatiles. We also used the VOC profiles of Allium samples to discriminate among groups of A. fistulosum, A. chinense (rakkyo), and A. tuberosum (Oriental garlic). As we found 12 metabolite peaks including dipropyl disulphide with significant changes in A. chinense and A. tuberosum when compared to the control cultivar, these metabolite peaks can be used for chemotaxonomic classification of A. chinense, tuberosum, and A. fistulosum. Compared to SPME-method our ITEX-based VOC profiling technique contributes to automatic and reproducible analyses. Hence, it can be applied to high-throughput analyses such as metabolite profiling.

Familiarity with coping strategies is essential for stress management during pregnancy. The Revised Prenatal Coping Inventory (Nu-PCI) was developed to assess coping strategies during pregnancy. This study aimed to assess the factor structure and psychometric properties of the Persian version of the Nu-PCI. After forward-backward translation, the Nu-PCI was administered to 210 pregnant women who were enrolled in two teaching referral clinics in the North of the Islamic Republic of Iran (Babol). The participants completed the Persian Nu-PCI and Ways of Coping Questionnaire (WCQ), which was used to determine the validity of the Persian Nu-PCI. To test construct validity of the Persian Nu-PCI, a principal components factor analysis was performed. Principal components analysis with varimax rotation showed a best fitting 3-factor structure similar to the original with three coping subscales: planning-preparation, avoidance, and spiritual-positive coping. The Persian Nu-PCI was internally consistent and within the acceptable range (α=0.89-0.97). The alpha coefficients for the Nu-PCI and the subscales of planning-preparation, avoidance, and spiritual-positive coping were high. Test-retest coefficients for the Nu-PCI and subscales were 0.98-0.99. The Nu-PCI and its subscales correlated with the WCQ in the entire sample and within each trimester. The Persian version of the Nu-PCI and the subscales of planning-preparation, avoidance, and spiritual-positive coping represent the first reliable standardized tool for measuring coping strategies during pregnancy in the Islamic Republic of Iran. Therefore, it can be applied as a quick and accurate preliminary screening tool for evaluating coping strategies throughout pregnancy in clinics and other medical and research settings.

The Patient Assessment of Constipation Quality of Life (PAC-QOL) questionnaire is the most validated and the most specific tool for measuring the quality of life of patients with constipation. Over 120 million people live in countries whose official language is Persian. There is no reported Persian version of the PAC-QOL questionnaire yet. The aim of this study was to translate and culturally adapt the PAC-QOL questionnaire and to assess its reliability and validity among Persian patients with chronic constipation. Following the translation and cultural adaptation of the PAC-QOL questionnaire to Persian, 100 patients (mean±SD age=40.51±13.67) with constipation were recruited for validity measurement and 20 patients were re-examined for reliability. Content validity was assessed based on the opinions of an expert committee and the floor/ceiling effect. Construct validity was evaluated according to the hypothesis test. The SF-36 questionnaire was used for concurrent criterion validity, intra-class correlation coefficient for reliability, and Cronbach's alpha for internal consistency. The content validity of the PAC-QOL questionnaire was proven, and there was no floor/ceiling effect. Construct validity also was confirmed based on the hypothesis test. The overall Cronbach's alpha of the PAC-QOL questionnaire was 0.92 (range=0.72-0.92), and the overall intra-class correlation coefficient of the questionnaire was 0.88 (range=0.69-0.87). The correlation between the SF-36 and PAC-QOL questionnaires was moderate. The Persian version of the PAC-QOL questionnaire demonstrated good validity and reliability properties in chronic constipation. Accordingly, Persian researchers and clinicians can benefit from this questionnaire in further research and assessment of treatment outcomes.

Microplastics (MPs) are well-known emerging contaminants in the marine environment. A key route by which MPs can directly affect marine life is through ingestion. The objective of the present study was to evaluate the occurrence of MPs in marine life and seafood for human consumption in the Persian Gulf. We conducted a whole body analysis of MP (between 10 and 5000 μm in diameter) abundance in five species of molluscs with different feeding strategies, including both gastropods and bivalves from the littoral zone of the Iranian coast of the Persian Gulf. The mean number of total encountered MPs in all species ranged from 0.2 to 21.0 particles per g of soft tissue (wet weight) and from 3.7 to 17.7 particles per individual. Overall, microfibres followed by fragments were the most common type of MP isolated in each species (respectively > 50% and ≈26%). Film (≈14%) and pellets (≈2%) were less commonly observed. The observed MPs were classified into three size groups (ca. 10-25 μm, 25-250 μm and 250-5000 μm), and 37-58% of MPs fell into the smallest size group. Fourier transform infrared (FT-IR) analysis confirmed the presence of polyethylene (PE), polyethylene terephthalate (PET), and nylon (PA). Our results indicated that molluscan shellfish from the Persian Gulf contain MPs, with higher concentrations in a predatory species, suggesting trophic transfer of MPs in the food web. The consumption of edible species may be a source of human microplastic intake. We compared our results with those previously reported for other regions of the world and identified the need for further studies in the Persian Gulf. Copyright © 2017 Elsevier Ltd.

The aim of this study was to develop, validate, and assess the reliability of the Persian version of Vocal Cord Dysfunction Questionnaire (VCDQ P ). The study design was cross-sectional or cultural survey. Forty-four patients with vocal fold dysfunction (VFD) and 40 healthy volunteers were recruited for the study. To assess the content validity, the prefinal questions were given to 15 experts to comment on its essential. Ten patients with VFD rated the importance of VCDQ P in detecting face validity. Eighteen of the patients with VFD completed the VCDQ 1 week later for test-retest reliability. To detect absolute reliability, standard error of measurement and smallest detected change were calculated. Concurrent validity was assessed by completing the Persian Chronic Obstructive Pulmonary Disease (COPD) Assessment Test (CAT) by 34 patients with VFD. Discriminant validity was measured from 34 participants. The VCDQ was further validated by administering the questionnaire to 40 healthy volunteers. Validation of the VCDQ as a treatment outcome tool was conducted in 18 patients with VFD using pre- and posttreatment scores. The internal consistency was confirmed (Cronbach α = 0.78). The test-retest reliability was excellent (intraclass correlation coefficient = 0.97). The standard error of measurement and smallest detected change values were acceptable (0.39 and 1.08, respectively). There was a significant correlation between the VCDQ P and the CAT total scores (P < 0.05). Discriminative validity was significantly different. The VCDQ scores in patients with VFD before and after treatment was significantly different (P < 0.001). The VCDQ was cross-culturally adapted to Persian and demonstrated to be a valid and reliable self-administered questionnaire in Persian-speaking population. Copyright © 2017 The Voice Foundation.

Investigation and research into the Persian Gardens, leading this project into a step that these World Heritage Sites might have been known as sustainable construction, but the fact that water scarcity of their region is a serious threaten for all these amazing Gardens. Thus, enhancing and improving these gardens by merging, adding and adapting todays technologies can make them considered as constructions with water and energy conservation design. Based on nowadays world environment concerns, recognizing renewable and non-renewable sources of energies in a region or site can cause a miracle. Since, almost all Persian Gardens located in regions with arid and semi-arid climate, water poverty as a biggest issue and nonrenewable energy should be included as a problematic concern. There are many available active and passive strategies that can be applied in these heritage sites which decrease water consumption either directly or indirectly. Such as water harvesting, greywater reuse, photovoltaic panels and material changes. Water known as a vital element of each garden for irrigation purposes, but in Persian Garden water is more than a functional element. Thus, finding a way to provide and recycle water beside the underground sources is necessary. Subterranean, springs and wells are resources of water for Persian gardens which renew so slowly or non-renew these days. Being so close to a city with considerable population lunches and idea of using greywater for irrigation in these gardens. In this research, the doable options for energy conservation design for these sites will be discussed, then comparing some case studies in all over world where greywater reusing water system for irrigation is happening will be next step. In conclusion, greywater reusing system in urban scale in order to irrigate a filed or garden will be investigate on a Shazdeh Garden as a main case study of this research.

Observational study. To cross-culturally translate the Orebro Musculoskeletal Pain Screening Questionnaire (OMPQ) into Persian and then evaluate its psychometric properties (reliability, validity, ceiling, and flooring effects). To the authors' knowledge, prior to this study there has been no validated instrument to screen the risk of chronicity in Persian-speaking patients with low back pain (LBP) in Iran. The OMPQ was specifically developed as a self-administered screening tool for assessing the risk of LBP chronicity. The forward-backward translation method was used for the translation and cross-cultural adaptation of the original questionnaire. In total, 202 patients with subacute LBP completed the OMPQ and the pain disability questionnaire (PDQ), which was used to assess convergent validity. 62 patients completed the OMPQ a week later as a retest. Slight changes were made to the OMPQ during the translation/cultural adaptation process; face validity of the Persian version was obtained. The Persian OMPQ showed excellent test-retest reliability (intraclass correlation coefficient=0.89). Its internal consistency was 0.71, and its convergent validity was confirmed by good correlation coefficient between the OMPQ and PDQ total scores ( r =0.72, p <0.05). No ceiling or floor effects were observed. The Persian version of the OMPQ is acceptable for the target society in terms of face validity, construct validity, reliability, and consistency. It is therefore considered a useful instrument for screening Iranian patients with LBP.

Within onion, Allium cepa L., the availability of disease resistance is limited. The identification of sources of resistance in related species, such as Allium roylei and Allium fistulosum, was a first step towards the improvement of onion cultivars by breeding. SNP markers linked to resistance and polymorphic between these related species and onion cultivars are a valuable tool to efficiently introgress disease resistance genes. In this paper we describe the identification and validation of SNP markers valuable for onion breeding. Transcriptome sequencing resulted in 192 million RNA seq reads from the interspecific F1 hybrid between A. roylei and A. fistulosum (RF) and nine onion cultivars. After assembly, reliable SNPs were discovered in about 36 % of the contigs. For genotyping of the interspecific three-way cross population, derived from a cross between an onion cultivar and the RF (CCxRF), 1100 SNPs that are polymorphic in RF and monomorphic in the onion cultivars (RF SNPs) were selected for the development of KASP assays. A molecular linkage map based on 667 RF-SNP markers was constructed for CCxRF. In addition, KASP assays were developed for 1600 onion-SNPs (SNPs polymorphic among onion cultivars). A second linkage map was constructed for an F2 of onion x A. roylei (F2(CxR)) that consisted of 182 onion-SNPs and 119 RF-SNPs, and 76 previously mapped markers. Markers co-segregating in both the F2(CxR) and the CCxRF population were used to assign the linkage groups of RF to onion chromosomes. To validate usefulness of these SNP markers, QTL mapping was applied in the CCxRF population that segregates for resistance to Botrytis squamosa and resulted in a QTL for resistance on chromosome 6 of A. roylei. Our research has more than doubled the publicly available marker sequences of expressed onion genes and two onion-related species. It resulted in a detailed genetic map for the interspecific CCxRF population. This is the first paper that reports the detection of

Ancient Persian Skywatching and Calendars

NASA Astrophysics Data System (ADS)

Sołtysiak, Arkadiusz

The peoples of Iran used lunisolar calendars until the early fifth century BCE when the 365-day calendar with 30 months and 5 epagomenal days was introduced. This calendar was not corrected to the actual length of the tropical year, and therefore, seasonal festivals gradually moved away from their seasons. Finally, around the turn of the fifth century CE, a partially successful calendar reform was undertaken, and the feasts were restored to their original seasons. In that time, Sasanian kings were interested in astrology, and some Greek and Hindu astrological texts were translated into Persian, but there is no evidence of indigenous contributions to skywatching.

There are various instruments and methods to evaluate spinal health and functional status. Whole-spine patient reported outcome (PRO) measures, such as the Spine Functional Index (SFI), assess the spine from the cervical to lumbo-sacral sections as a single kinetic chain. The aim of this study was to cross-culturally adapt the SFI for Persian speaking patients (SFI-Pr) and determine the psychometric properties of reliability and validity (convergent and construct) in a Persian patient population. The SFI (English) PRO was translated into Persian according to published guidelines. Consecutive symptomatic spine patients (104 female and 120 male aged between 18 and 60) were recruited from three Iranian physiotherapy centers. Test-retest reliability was performed in a sub-sample (n = 31) at baseline and repeated between days 3-7. Convergent validity was determined by calculating the Pearson's r correlation coefficient between the SFI-Pr and the Persian Roland Morris Questionnaire (RMQ) for back pain patients and the Neck Disability Index (NDI) for neck patients. Internal consistency was assessed using Cronbach's α. Exploratory Factor Analysis (EFA) used Maximum Likelihood Extraction followed by Confirmatory Factor Analysis (CFA). High levels of internal consistency (α = 0.81, item range = 0.78-0.82) and test-retest reliability (r = 0.96, item range = 0.83-0.98) were obtained. Convergent validity was very good between the SFI and RMQ (r = 0.69) and good between the SFI and NDI (r = 0.57). The EFA from the perspective of parsimony suggests a one-factor solution that explained 26.5% of total variance. The CFA was inconclusive of the one factor structure as the sample size was inadequate. There were no floor or ceiling effects. The SFI-Pr PRO can be applied as a specific whole-spine status assessment instrument for clinical and research studies in Persian language populations.

Nowadays, World Wide Web is an accessible and widespread resource to attain medical information. So physicians and health institutions try to inform patients about different domains of medicine through Web. Addiction is a noteworthy subject in medicine and a controversial issue among them. However, quality of health information on the internet is doubtful. The objective of this study is to determine the quality of Persian addiction websites to offer recommendation for their improvement. This was survey and an applied study that the study population was all Persian addiction websites. Sample of this study was 28 Persian addiction website which were chosen by searching Persian equivalences of 7 key terms (addiction, addict, addiction center, drug, treatment of addiction, recovery of addiction, addiction withdrawal) into the Google and Yahoo search engines. Finally, the websites were ranked based on the Silberg, DISCERN and WQET instruments. Data were analyzed with Excel software using descriptive statistics. The overall mean of websites in Silberg, DISCERN and WQET instruments were 1.42, 41.89, 64.57. Also the results showed that "Unit of Substance Abuse Treatment" belonging to Mashhad University of Medical Sciences was ranked first based on the Silberg, DISCERN and WQET instruments. 5 (from total of 9), 60 (from total of 80) and 82 (from total of normalized grade 82) were grades for this website for these instruments respectively. It showed that the quality of Persian websites according to Silberg, DISCERN and WQET instruments was "low", "more than half" and "very good" respectively. Not assigning date of entering data, author names, and references of information (authority) were most important missing characteristics of these websites. In addition, lack of interactive opportunities like chat rooms was another problem that leads to dissatisfaction of users.

Introduction: In the present era, thesauri as tools in indexing play an effective role in integrating retrieval preventing fragmentation as well as a multiplicity of terminologies and also in providing information content of documents. Goals: This study aimed to investigate the keywords of articles indexed in IranMedex in terms of origin, structure and indexing situation and their Compliance with the Persian Medical Thesaurus and Medical Subject Headings (MeSH). Materials and Methods: This study is an applied research, and a survey has been conducted. Statistical population includes 32,850 Persian articles which are indexed in the IranMedex during the years 1385–1391. 379 cases were selected as sample of the study. Data collection was done using a checklist. In analyzing the findings, the SPSS Software were used. Findings: Although there was no significant difference in terms of indexing origin between the proportion of different types of the Persian and English keywords of articles indexed in the IranMedex, the compliance rates of the Persian and English keywords with the Persian medical thesaurus and MeSH were different in different years. In the meantime, the structure of keywords is leaning more towards phrase structure, and a single word structure and the majority of keywords are selected from the titles and abstracts. Conclusion: The authors’ familiarity with the thesauri and controlled tools causes homogeneity in assigning keywords and also provides more precise, faster, and easier retrieval of the keywords. It's suggested that a mixture of natural and control languages to be used in this database in order to reach more comprehensive results. PMID:28546967

Family Dermatology Life Quality Index (FDLQI) is an instrument for assessing the quality of life of family members of dermatologic patients. The aim of this study was to describe the cultural adaptation of this questionnaire and to assess psychometric properties of the Persian version. At first, the questionnaire was translated into Persian, and then back-translation was performed. The whole cycle was repeated until a consensus was reached about the optimal translation. In the next step, cognitive debriefing was performed, and after approval of the Persian version by FDLQI developers, it was distributed among 100 family members of dermatological patients in order to evaluate its validity and reliability. Mean age of participants was 37.1 years (±12.3). Mean score of FDLQI was 15.4 (±5.5) with maximum and minimum scores of 30 and 6, respectively. The quality of life of studied participants showed no significant difference based on age-group, sex, educational level and the family relationship. Cronbach's alpha was calculated as 0.87. Exploratory factor analysis revealed a one-factor solution that accounted for 40.7 % of the variance. The unidimensional model was supported by confirmatory factor analysis. The results of the present study showed that the Persian version of FDLQI has acceptable factorial validity and internal consistency reliability.

Tinnitus is a debilitating condition that is widespread yet difficult to successfully diagnose and treat. This symptom can seriously affect the individual's life quality. The aim of current study was to compose and validate a Persian version of the Tinnitus Handicap Inventory (THI-P). The linguistic validation of the original version of THI into Persian version (THI-P) included translation, back translation and data gathering. The THI-P was administered to 112 tinnitus subjects. Age, gender, medical history and tinnitus characteristics were recorded as baseline information. All participants complained of chronic unilateral or bilateral subjective idiopathic tinnitus lasting for at least 6 months before consulting about their tinnitus. There was no significant difference between gender, age, hearing impairment and total score and subscales of THI-P. Pearson product-moment correlations revealed adequate test-retest reliability for the THI-P (r = 0.96). Cronbach's-alpha coefficient indicated adequate internal stability of the THI-P (r= 0.943), with a total item correction varying between r=0.939 and r=0.944, indicating its reproducibility. The present study proved the internal consistency/ coherency of the Persian version of THI (THI-P). This provides satisfactory application in clinical/research environments.

Intimal hyperplasia is associated with graft failure and vascular sutures in the first year after surgery and in postangioplasty restenosis. Allium sativum (common garlic) lowers cholesterol and has antioxidant effects; it also has antiplatelet and antitumor properties and, therefore, has great potential to reduce or inhibit intimal hyperplasia of the arteries. Our objective is to determine if the garlic has an efficacy to inhibit myointimal hyperplasia compared to cilostazol. Female New Zealand rabbits were divided into the following groups (n=10 each) according to treatment: group A, garlic, 800 µg×kg-1×day-1, orally; group C, cilostazol, 50 mg.day-1, orally; group PS, 10 ml of 0.9% physiological saline solution, orally. Our primary is the difference of the mean of myointimal hyperplasia. Statistical analysis was performed by using ANOVA and Tukey tests, as well as the Chi-square test. We calculated the 95% confidence interval for each point estimate, and the P value was set as < 0.05. Group PS had a mean hyperplasia rate of 35.74% (95% CI, 31.76-39.71%); group C, 16.21% (95% CI, 13.36-19.05%); and group A, 21.12% (95% CI, 17.26-25.01%); P < 0.0001. We conclude that Allium sativum had the same efficacy in inhibiting myointimal hyperplasia when compared to the positive control, cilostazol.

Garlic has played an important role in culinary arts and remedies in the traditional medicine throughout human history. Parasitic infections represent a burden in the society of especially poor countries, causing more than 1 billion infections every year and leading to around one million deaths. In this study, we investigated the mode of anti-parasitic activity of "wild garlics" Tulbaghia violacea and Allium ursinum dichloromethane extracts against parasites Trypanosoma brucei brucei and Leishmania tarentolae with regard to their already known antimicrobial activity. We also evaluated their cytotoxic potential against human cells. Both extracts showed a relevant trypanocidal and leishmanicidal activity, although L. tarentolae was less sensitive. We determined that the probable mode of action of both extracts is the irreversible inhibition of the activity of Trypanosoma brucei trypanothione reductase enzyme. The extracts showed a mild cytotoxic activity against human keratinocytes. They also exhibited weak-in most cases comparable-antibacterial and antifungal activity. HPLC-MS/MS analysis showed that both extracts are abundant in sulfur compounds. Thus, for the first time, the ability of Allium ursinum and Tulbaghia violacea to kill Trypanosoma sp. and Leishmania sp. parasites, probably by binding to and inactivating sulfur-containing compounds essential for the survival of the parasite, is shown.

Fear of falling may be related to falling during stroke onset. The Fall Efficacy ScaleInternational (FES-I) with excellent psychometric properties, is an instrument developed to assess patients' concerns about fallings. The aim of this study was to determine validation of this scale in Iranian patients with stroke. The "forward-backward" procedure was applied to translate the FES-I from English to Persian. One hundred-twenty patients who had suffered stroke, aged 40 to 80 years (55% male) completed the Persian FES-I, Geriatric Depression Scale-15 (GDS-15), General Health Questionnaire-28 (GHQ-28), Berg Balance Scale (BBS) and Timed up and Go (TUG) questionnaires. The interval time for the test-retest of the Persian scale was 7-14 days. The test-retest and inter-rater reliabilities of the Persian FES-I were excellent (ICC2,1=0.98, p<0.001) and the internal consistency was high (Cronbach's alpha=0.78). Factor analysis of the 16 items in the Persian scale showed only one significant factor. The total Persian FES-I score had a significantly negative correlation (p<0.001) with the BBS, but it had significantly positive correlation with the TUG, GHQ-28, and GDS-15. The difference in responsiveness scores across fallers and non-fallers yielded a large effect size (0.46), which indicated a good discriminating validity. The Persian FES-I proved to be an effective and valuable measurement tool to assess stroke patients' fear of falling in practice and research setting.

God Locus of Health Control (GHLC) scale is an instrument for assessing to what extent one believes that God controls his/her health or disease. The aim of this study was to describe the cultural adaptation of this scale and to investigate the psychometric properties of Persian version. At first, the scale was forward-translated to Persian, and then, backward-translation was conducted. Finally, the synthesized back-translated version was prepared and compared to the draft Persian-language version of the GLHC. In the next step, in order to test cognitive debriefing, the Persian-language version of the questionnaire was completed by 20 pilgrims. Final version of Persian GHLC scale was answered by 600 pilgrims attending religious holy places. Mean age of respondents was 33.15 (±11.04) years. There was a positive correlation between six items of GLHC scale and inter-item correlation coefficients. The Cronbach's alpha coefficient was 0.84. Exploratory factor analysis showed that the G LHC scale had a one-factor structure. The factor loadings for all items ranged from 0.57 to 0.77. Residual correlations of all items were between -0.2 and +0.2. The people with lower income had significantly higher score of GLHC scale. GLHC scale score had a significant positive correlation with DUREL subscale and MHLC Chance Externality subscale score. There was no a significant correlation between GLHC scale score and Multidimensional Health Locus of Control (MHLC) Internality and Powerful subscales scores. The results of the present study showed that the Persian version of GHLC scale has acceptable factorial validity and internal consistency reliability.

Dizziness and vertigo are the most common complaints of patients that has a high economic burden on the health system. In modern medicine, treatment for dizziness and vertigo consists of chemical pharmacological therapy. Although these drugs are useful in controlling the disease, their side effects and inefficiency in full control of the disease require the use of complementary medicine in this field. Persian medicine consists of valuable experiences of Persian medicine scholars based on the theory of humors and temperaments. In Persian medicine, 2 types of disease are presented: dizziness (sadar) and vertigo (dovar). Persian medicine physicians expressed a different mechanism of action than modern medicine for these diseases. They believed that accumulation of abnormal humors, reeh (normal bloating) or causative pathologic substances, is the basic cause of sadar and dovar and that the most important treatment is cleansing the body, particularly the head from accumulated substances by bloodletting methods.

Methamphetamine use is a new health concern in Iran, the most populated Persian Gulf country. However, there is no well-documented literature. The current study objectives were to systematically review all published English and Persian studies of the prevalence of methamphetamine use, the general physical and psychiatric-related harms and the availability of methamphetamine treatment and harm reduction services for adult users in Iran. A comprehensive search of the international peer-reviewed and gray literature was undertaken. Multiple electronic and scientific English and Persian databases were systematically searched from January 2002 to September 2014. Additionally, English and Persian gray literature on methamphetamine use was sought using online gray literature databases, library databases and general online searches over the same period of time. Nineteen thousand and two hundred and eight studies, reports and conference papers were identified but only 42 studies were relevant to the study objectives. They were mainly published in 2010-2014. The search results confirmed the seizures of methamphetamine (six studies), the prevalence of methamphetamine use among the general population (three studies), drug users (four studies), women (nine studies) and opiate users in opiate treatment programs (five studies). In addition, methamphetamine use had resulted in blood-borne viral infections (one study), psychosis and intoxication (ten studies). Different reasons had facilitated methamphetamine use. However, the Matrix Model, community therapy and harm reduction services (four studies) had been provided for methamphetamine users in some cities. The current situation of methamphetamine use necessitates more research on the epidemiology and health-related implications. These studies should help in identifying priorities for designing and implementing prevention and educational programs. More active models of engagement with Persian methamphetamine users and the

Almost everybody knows that soils are the foundation of food production and foodsecurity, supplying plants with nutrients, water and supports for their roots, but how many people or policy makes know that: Soil is a Complex, Dynamic, Open System and life also is the same! Increasing public awareness about soil-related outreach involves the dissemination and acceptance of information about soil to stakeholders who have not been aware of its importance. Public awareness can support efforts to involve private sector, indigenous and local communities and NGOs to engage on soil related activities. In this regard utilization of cultural and traditional understanding of soil issues (ethnopedology, art, literature, customs, and poems) is essential and vital to promote soil awareness among policy-makers, donors and the general public in order to find better understanding of soil's role in global issues such as climate change. In this paper we extensively analysis Persian and Iranian poems in order to get better understanding of cultural patterns of soils and its contribution to society. In ancient Cultures Classical elements (earth(Soil), water, air, fire,) explained the nature of all matters around the world, same as many other, in Persian. Each of these elements has their nature and personalities. Soil also refers to one part of human's life cycle. After death we join to soil. Therefore in Persian culture and poetry there is lots of poem which express these concepts such as poem below of Umar Khayyam Neyshabouri which noted the importance and the nature of soil and its relation to vegetation, and their cause-effect relationships about one thousand years ago. "Every unique herb vegetated next to a stream/ is as if grown from the lip of an angelical beauty/ don't stampede (degrade) that herb/ because it is vegetated from the soil of a beauty whose face is like a tulip". and Look how the morning breeze has helped the rosebud bloom/ And how at the sight of the rose the

Emotion perception plays a major role in proper communication with people in different social interactions. Nonverbal affect bursts can be used to evaluate vocal emotion perception. The present study was a preliminary step to establishing the psychometric properties of the Persian version of the Montreal Affective Voices (MAV) test, as well as to investigate the effect of Parkinson disease (PD) on vocal emotion perception. The short, emotional sound made by pronouncing the vowel "a" in Persian was recorded by 22 actors and actresses to develop the Persian version of the MAV, the Persian Affective Voices (PAV), for emotions of happiness, sadness, pleasure, pain, anger, disgust, fear, surprise, and neutrality. The results of the recordings of five of the actresses and five of the actors who obtained the highest score were used to generate the test. For convergent validity assessment, the correlation between the PAV and a speech prosody comprehension test was examined using a gender- and age-matched control group. To investigate the effect of the PD on emotion perception, the PAV test was performed on 28 patients with mild PD between ages 50 and 70 years. The PAV showed a high internal consistency (Cronbach's α = 0.80). A significant positive correlation was observed between the PAV and the speech prosody comprehension test. The test-retest reliability also showed the high repeatability of the PAV (intraclass correlation coefficient = 0.815, P ≤ 0.001). A significant difference was observed between the patients with PD and the controls in all subtests. The PAV test is a useful psychometric tool for examining vocal emotion perception that can be used in both behavioral and neuroimaging studies. Copyright © 2018 The Voice Foundation.

Neurodegenerative diseases are a progressive loss of structure and/or function of neurons. Weak therapeutic response and progressive nature of the diseases, as well as a wide range of side effects caused by conventional therapeutic approaches make patients seek for complementary and alternative medicine. The aim of the present paper is to discuss the neuropharmacological basis of medicinal plants and their principle phytochemicals which have been used in traditional Persian medicine for different types of neurodegenerative diseases. Medicinal plants introduced in traditional Persian medicine perform beneficial effects in neurodegenerative diseases via various cellular and molecular mechanisms including suppression of apoptosis mediated by an increase in the expression of anti-apoptotic agents (e.g. Bcl-2) as well as a decrease in the expression and activity of proapoptotic proteins (e.g. Bax, caspase 3 and 9). Alleviating inflammatory responses and suppressing the expression and function of pro-inflammatory cytokines like Tumor necrosis factor α and interleukins, as well as improvement in antioxidative performance mediated by superoxide dismutase and catalase, are among other neuroprotective mechanisms of traditional medicinal plants. Modulation of transcription, transduction, intracellular signaling pathways including ERK, p38, and MAPK, with upstream regulatory activity on inflammatory cascades, apoptosis and oxidative stress associated pathways, play an essential role in the preventive and therapeutic potential of the plants in neurodegenerative diseases. Medicinal plants used in traditional Persian medicine along with their related phytochemicals by affecting various neuropharmacological pathways can be considered as future drugs or adjuvant therapies with conventional pharmacotherapeutics; though, further clinical studies are necessary for the confirmation of their safety and efficacy.

Background Perceptions of aging refer to individuals’ understanding of aging within their sociocultural context. Proper measurement of this concept in various societies requires accurate tools. Objective The present study was conducted with the aim to translate and validate the Brief Aging Perceptions Questionnaire (B-APQ) and assess its psychometric features in Iranian older adults. Method In this study, the Persian version of B-APQ was validated for 400 older adults. This questionnaire was translated into Persian according to the Wild et al’s model. The Persian version was validated using content, face, and construct (using confirmatory factor analysis) validities, and then its internal consistency and test–retest reliability were measured. Data were analyzed using the statistical software programs SPSS 18 and EQS-6.1. Results The confirmatory factor analysis confirmed construct validity and five subscales of B-APQ. Test–retest reliability with 3-week interval produced r=0.94. Cronbach’s alpha was found to be 0.75 for the whole questionnaire, and from 0.53 to 0.77 for the five factors. Conclusion The Persian version of B-APQ showed favorable validity and reliability, and thus it can be used for measuring different dimensions of perceptions of aging in Iranian older adults.

Plants of the Allium genus produce sulphur compounds that give them a characteristic (alliaceous) flavour and mediate for their medicinal use. In this study, the chemical composition and antimicrobial properties of Allium cepa red cv. and A. sativum in the context of three different drying processes were assessed using metabolomics. Bulbs were dried using either microwave, air drying, or freeze drying and further subjected to chemical analysis of their composition of volatile and non-volatile metabolites. Volatiles were collected using solid phase micro-extraction (SPME) coupled to gas chromatography-mass spectrometry (GC/MS) with 42 identified volatiles including 30 sulphur compounds, four nitriles, three aromatics, and three esters. Profiling of the polar non-volatile metabolites via ultra-performance liquid chromatography coupled to high resolution MS (UPLC/MS) annotated 51 metabolites including dipeptides, flavonoids, phenolic acids, and fatty acids. Major peaks in GC/MS or UPLC/MS contributing to the discrimination between A. sativum and A. cepa red cv. were assigned to sulphur compounds and flavonoids. Whereas sulphur conjugates amounted to the major forms in A. sativum , flavonoids predominated in the chemical composition of A. cepa red cv. With regard to drying impact on Allium metabolites, notable and clear separations among specimens were revealed using principal component analysis (PCA). The PCA scores plot of the UPLC/MS dataset showed closer metabolite composition of microwave dried specimens to freeze dried ones, and distant from air dried bulbs, observed in both A. cepa and A. sativum . Compared to GC/MS, the UPLC/MS derived PCA model was more consistent and better in assessing the impact of drying on Allium metabolism. A phthalate derivative was found exclusively in a commercial garlic preparation via GC/MS, of yet unknown origin. The freeze dried samples of both Allium species exhibited stronger antimicrobial activities compared to dried specimens

In humans, efficient recognition of written symbols is thought to rely on a hierarchical processing system, where simple features are progressively combined into more abstract, high-level representations. Here, we present a computational model of Persian character recognition based on deep belief networks, where increasingly more complex visual features emerge in a completely unsupervised manner by fitting a hierarchical generative model to the sensory data. Crucially, high-level internal representations emerging from unsupervised deep learning can be easily read out by a linear classifier, achieving state-of-the-art recognition accuracy. Furthermore, we tested the hypothesis that handwritten digits and letters share many common visual features: A generative model that captures the statistical structure of the letters distribution should therefore also support the recognition of written digits. To this aim, deep networks trained on Persian letters were used to build high-level representations of Persian digits, which were indeed read out with high accuracy. Our simulations show that complex visual features, such as those mediating the identification of Persian symbols, can emerge from unsupervised learning in multilayered neural networks and can support knowledge transfer across related domains.

Objective Intimal hyperplasia is associated with graft failure and vascular sutures in the first year after surgery and in postangioplasty restenosis. Allium sativum (common garlic) lowers cholesterol and has antioxidant effects; it also has antiplatelet and antitumor properties and, therefore, has great potential to reduce or inhibit intimal hyperplasia of the arteries. Our objective is to determine if the garlic has an efficacy to inhibit myointimal hyperplasia compared to cilostazol. Methods Female New Zealand rabbits were divided into the following groups (n=10 each) according to treatment: group A, garlic, 800 µg×kg-1×day-1, orally; group C, cilostazol, 50 mg.day-1, orally; group PS, 10 ml of 0.9% physiological saline solution, orally. Our primary is the difference of the mean of myointimal hyperplasia. Statistical analysis was performed by using ANOVA and Tukey tests, as well as the Chi-square test. We calculated the 95% confidence interval for each point estimate, and the P value was set as < 0.05. Results Group PS had a mean hyperplasia rate of 35.74% (95% CI, 31.76–39.71%); group C, 16.21% (95% CI, 13.36–19.05%); and group A, 21.12% (95% CI, 17.26–25.01%); P<0.0001. Conclusion We conclude that Allium sativum had the same efficacy in inhibiting myointimal hyperplasia when compared to the positive control, cilostazol. PMID:27849301

A number of urethral stents made of different materials, with different time of indwelling and different designs, primarily based on the vascular stent concept, have been applied in the clinical practice so far. According to the published studies, urethral stents have justified their clinical application, however with certain limitations. Within an attempt to overcome the limitations, a covered, temporary urethral stent was initially designed by Daniel Yachie and Ijko Markovi in Allium corporation from Israel. With its triangular shape, the stent is a replica of the obstructive prostatic urethral lumen. In has been applied in a series of 14 patients with lower urinary tract symptoms caused by the obstruction at the level of the prostatic urethra. The subjects were averagely aged 77.4 +/- 5.1 years. Allium prostatic stent remained in place in the patients for 4.93 +/- 3.17 months, at the average.

Practical astronomy in Indo-Persian sources

Ansari, S. M. R.

In the classical survey of zij literature (by E. Kennedy, 1956), out of 220 listed zijes only three zijes compiled in India are mentioned. They are: Zij-i Jami', ca 1461/62 (Kennedy serial No. X220); Zij-i Shahjahani, ca 1610 (X204); Zij-i Muhammad Shahi, ca 1730 (X203). However, since that classical survey, a number of Indian zijes have been found to be extant. They are: Zij-i Nasiri (ca 1260), Zij-i Nizami (ca 1780), Zij-i Hindi (1805), Zij-i 'Alami (ca 1808), Zij-i Ashki (1816), Zij-i Safdari (1819), Zij-i Sulayman Jahi (1830) and Zij-i Bahadur Khani (1838). It is well known that a zij comprises astronomical-mathematical and also astrological tables for use in practical or observational astronomy. From the standpoint of applied astronomy, it consists of particularly eclipse tables, visibility tables - for lunar crescent, apparitions and disappearances of planets - geographical and star tables. Evidently, this tabulated material can be used for the studies in applied astronomy. Besides zijes, we find also other classes of literature in which are treated the observations of comets, fireballs and meteorites. They are treatises on atmospheric phenomena (Athar-i 'Ulawi), chronicles and histories of Medieval India in Persian. For instance, we have histories by Abul Fadl and 'Arif Qandhari (16-17th c.), al-Husayni (18th c.), to name just a few. In this paper, we describe briefly the above-mentioned Indo-Persian sources, list the various celestial phenomena along with their short account as given in these sources, particularly in the Indian zijes. Finally, we make some remarks about their use in applied astronomy.

The aim of this study was to validate a Persian version of the Cardiac Depression Scale (CDS) in Iranian patients with acute myocardial infarction (AMI). The CDS was forward translated from English into Persian and back-translated to English. Validity was assessed using face, content, and construct validity. Also Cronbach's alpha (α), theta (), and McDonald's omega coefficient were used to evaluate the reliability. Construct validity of the scale showed two factors with eigenvalues greater than one. The Cronbach's α, , McDonald's omega, and construct reliability were greater than .70. The Persian version of the CDS has a two-factor structure (i.e., death anxiety and life satisfaction) and has acceptable reliability and validity. Therefore, the validated instrument can be used in future studies to assess depression in patients with AMI in Iranians.

In the past, communicable diseases caused the highest mortality in Iran. Improvements in socioeconomic status and living standards including access to safe drinking water, along with the inception of Health Houses in the 1980s, have changed disease patterns, decreasing the spread of and deaths from infectious and communicable diseases. The incidence and prevalence of non-communicable diseases (NCD), however, have now increased in Iran, accounting for nearly 80% of deaths and disabilities. Without interventions, NCD are predicted to impose a substantial human and economic burden in the next 2 decades. However, Iran's health system is not equipped with the necessary policies to combat this growth and must refocus and reform. Therefore, in the year 2013, the Ministry of Health and Medical Education funded a well-designed nationwide cohort study-Prospective Epidemiological Research Studies in IrAN (PERSIAN)-in order to assess the burden of NCD and investigate the risk factors associated with them in the different ethnicities and geographical areas of Iran. The PERSIAN Cohort, which aims to include 200000 participants, has 4 components: Adult (main), Birth, Youth and Elderly, which are being carried out in 22 different regions of Iran. Having an enormous dataset along with a biobank of blood, urine, hair and nail samples, the PERSIAN Cohort will serve as an important infrastructure for future implementation research and will provide the evidence needed for new healthcare policies in order to better control, manage and prevent NCD.

Psychometric testing of the Persian version of Pain Anxiety Symptom Scale 20. The aim of this study was to assess the reliability and construct validity of the PASS-20 in nonspecific chronic low back pain (LBP) patients. The PASS-20 is a self-report questionnaire that assesses pain-related anxiety. The Psychometric properties of this instrument have not been assessed in Persian-speaking chronic LBP patients. One hundred and sixty participants with chronic LBP completed the Persian version of PASS-20, Tampa Scale of Kinesiophobia (TSK), Fear-Avoidance Beliefs Questionnaire (FABQ), Pain Catastrophizing Scale (PCS), trait form of the State-Trait Anxiety (STAI-T), Oswestry Low Back Pain Disability Index (ODI), Beck Depression Inventory (BDI-II), and Visual Analogue Scale (VAS). To evaluate test-retest reliability, 60 patients filled out the PASS-20, 6 to 8 days after the first visit. Test-retest reliability (intraclass correlation coefficient [ICC], standard error of measurement [SEM], and minimal detectable change [MDC]), internal consistency, dimensionality, and construct validity were examined. The ICCs of the PASS-20 subscales and total score ranged from 0.71 to 0.8. The SEMs for PASS-20 total score was 7.29 and for the subscales ranged from 2.43 to 2.98. The MDC for the total score was 20.14 and for the subscales ranged from 6.71 to 8.23. The Cronbach alpha values for the subscales and total score ranged from 0.70 to 0.91. Significant positive correlations were found between the PASS-20 total score and PCS, TSK, FABQ, ODI, BDI, STAI-T, and pain intensity. The Persian version of the PASS-20 showed acceptable psychometric properties for the assessment of pain-related anxiety in Persian-speaking patients with chronic LBP. 3.

Overactive bladder syndrome is a common syndrome in the world in both men and women. Correct diagnosis and accurate measurement of symptoms severity and also quality of life of patients is necessary to ensure proper treatment and to facilitate sound relationships among patients, researchers and doctors. The International Consultation on Incontinence Questionnaire in Over Active Bladder (ICIQ-OAB) questionnaire is a concise and strong tool to evaluate the symptoms of OAB and their effects on patients' quality of life and treatment results. The objective of this study was to translate and validate a simple and strong tool that could be used in clinics and research. First, the original British English questionnaire was translated into Persian by two bilingual and originally Persian-speaking translators. Then the Persian version was back translated to English and a native English speaker studied and compared the questionnaire with the original version. At the end, the translated and corrected Persian version was finalized by a research team. Content validity of the items and ensuring that the questions could convey the main concept to readers was assessed through Modified Content Validity Index (MCVI). Reliability was calculated by Cronbach's α coefficient. Internal Consistency of the questionnaire with the calculation of Kendall correlation coefficient were evaluated by performing test-retest in 50 participants. The modified content validity index was > 0.78 for all of the questions. Cronbach's α coefficient was calculated 0.76 for all of the participants. Kendall correlation coefficient was calculated for test-re-test assessment 0.66. Both of which indicates the reliability of this questionnaire. Persian version of ICIQ-OAB questionnaire is a simple and strong tool for research, treatment and screening purposes. © 2014 Wiley Publishing Asia Pty Ltd.

Cerebrovascular disease leading to stroke is the most common cause of aphasia. Speakers with agrammatic non-fluent aphasia have difficulties in production of movement-derived sentences such as passive sentences, topicalized constituents, and Wh-questions. To assess the production of complex sentences, some passive, topicalized and focused sentences were designed for patients with non-fluent Persian aphasic. Afterwards, patients' performance in sentence production was tested and compared with healthy non-damaged subjects. In this cross sectional study, a task was designed to assess the different types of sentences (active, passive, topicalized and focused) adapted to Persian structures. Seven Persian patients with post-stroke non-fluent agrammatic aphasia (5 men and 2 women) and seven healthy non-damaged subjects participated in this study. The computed tomography (CT) scan or magnetic resonance imaging (MRI) showed that all the patients had a single left hemisphere lesion involved middle cerebral artery (MCA), Broca`s area and in its white matter. In addition, based on Bedside version of Persian Western Aphasia Battery (P-WAB-1), all of them were diagnosed with moderate Broca aphasia. Then, the production task of Persian complex sentences was administered. There was a significant difference between four types of sentences in patients with aphasia [Degree of freedom (df) = 3, P < 0.001]. All the patients showed worse performance than the healthy participants in all the four types of sentence production (P < 0.050). In general, it is concluded that topicalized and focused sentences as non-canonical complex sentences in Persian are very difficult to produce for patients with agrammatic non-fluent aphasia. It seems that sentences with A-movement are simpler for the patients than sentences involving A`-movement; since they include shorter movements in compare to topicalized and focused sentences.

We examined the habitat use of fish larvae in the northern Persian Gulf from July 2006 to June 2007. Correspondence Analysis showed significant differences between hydrological seasons in habitat use and structure of larval fish assemblages, while no differences were found regarding abundance among coralline and non-coralline habitats. The observed configuration resulted in part from seasonal reproductive patterns of dominant fish influencing the ratio pelagic:demersal spawned larvae. The ratio increased along with temperature and chlorophyll-a concentration, which likely fostered the reproduction of pelagic spawner fish. The close covariation with temperature throughout hydrographic seasons suggests a leading role of temperature in the seasonal structure of larvae assemblages. Our results provide new insights on fish larval ecology in a traditionally sub-sampled and highly exposed zone to anthropogenic pollution, the northern Persian Gulf, and highlight the potential role of Khark and Kharko Islands in conservation and fishery management in the area.

Functional constipation (FC) is a common clinical condition without any specific physiological causes with economic cost and adverse effects on patients' quality of life. The present study aimed to evaluate the causes of nonobstructive constipation in traditional Persian medicine and its prevalence in patients with functional constipation by content analysis of patients' interviews and clinical exams. In this study, almost two thirds of the patients with functional constipation had mild to severe cold distemperament of the gastrointestinal system, and in almost half of them the signs and symptoms were compatible with dry distemperament of the gastrointestinal. This observational study reports high prevalence of gastrointestinal system distemperaments in patients with functional constipation. According to the results, we can consider the proposed management of distemperaments in traditional Persian medicine for functional constipation treatment and pathophysiology explanation. This project is a novel study that provides the opportunity for investigating the epidemiological aspects of these distemperaments and their relationship with functional constipation. © The Author(s) 2015.

Forskolin, a diterpene, 7β-acetoxy-8,13-epoxy-1α,6β,9α-trihydroxy-labd-14-en-11-one (C22H34O7) isolated from Coleus forskohlii, exerts multiple physiological effects by stimulating the enzyme adenylate cyclase and increasing cyclic adenosine monophosphate (cAMP) concentrations. Forskolin is used in the treatment of hypertension, congestive heart failure, eczema, and other diseases. A cytogenetic assay was performed in Allium cepa to assess possible genotoxic effects of forskolin. Forskolin was tested at concentrations 5-100 μM for exposure periods of 24 or 48 h. Treated samples showed significant reductions in mitotic index (p < 0.05) and increases in the frequency of chromosome aberrations (p < 0.01) at both exposure times. The treated meristems showed chromosome aberrations including sticky metaphases, sticky anaphases, laggard, anaphase bridges, micronuclei, polyploidy, fragments, breaks, and C-mitosis. Forskolin may cause genotoxic effects and further toxicological evaluations should be conducted to ensure its safety. Copyright © 2014 Elsevier B.V. All rights reserved.

Burn as a traumatic life incident manifests severe pain and psychological problems. Specific instruments are needed to evaluate burn patients' psychological issues related to the injury. The aim of this study was to translate and evaluate the reliability and validity of the Persian versions of Impact of Burn Specific Pain Anxiety scale (BSPAS) and Impact of Event Scale (IES). In this cross-sectional study, convenience sampling method was utilized to select 55 Iranian hospitalized burn patients. Combined translation was utilized for translating scales. Alpha cronbach, item-total correlation, convergent and discriminative validity were evaluated. The Cronbach's α for both BSPAS- and IES-Persian version was 0.96. Item-total correlation coefficients ranged from 0.70 to 0.90. Convergent construct validity was confirmed by indicating high correlation between the scales designed to measure the same concepts. The mean score of BSPAS- and IES-Persian version was lower for individuals with a lower TBSA burn percentage which assessed discriminative construct validity of scales. BSPAS- and IES-Persian version showed high internal consistency and good validity for the assessment of burn psychological outcome in hospitalized burn patients. Future studies are needed to determine repeatability, factor structure, sensitivity and specificity of the scales. Copyright © 2013 Elsevier Ltd and ISBI. All rights reserved.

Exploring Emotive Verbs in Persian and English Short Stories: A Contrastive Sociopragmatic Approach.

2017-04-01

Current developments in the areas of discourse analysis and cross-cultural studies have led to an increased interest in the way people of different cultures express their affections on various occasions. Individuals learn how to regulate their emotional reactions according to sociocultural norms of behavior defined by the cultures to which they belong. Accordingly, this article aimed to investigate the linguistic expression of emotions in English and Persian short stories in order to fathom out the impact of culture on the way feelings are expressed cross-culturally. For this purpose, a corpus of eight different English and Persian short stories, four in each language, was selected based on a purposive sampling method. Then, using Devon's (The origin of emotions, 2006) typology of emotions, different types of emotive verbs were selected as the unit of analysis. Finally, the frequency and percentage values of emotive verb tokens used in these stories were carefully tabulated in terms of types and their respective metalinguistic categories introduced by Wierzbicka (Emotions across languages and cultures: diversity and universals, Cambridge University Press, Cambridge, 1999). The results obtained from the analysis of the targeted corpora reflected that English and Persian writers employ different types of emotive verbs in expressing their feelings. Essentially, the findings of the present study may have important implications for language teachers, material developers, and course designers.

The aim of this methodological study was to cross-culturally translate the Shoulder Activity Scale (SAS) into the Persian and determine its clinimetric properties including reliability, validity, and responsiveness in patients with shoulder disorders. Persian version of the SAS was obtained after standard forward-backward translation. Three questionnaires were completed by the respondents: SAS, shoulder pain and disability index (SPADI), and Short-Form 36 Health Survey (SF-36). The patients completed the SAS, 1 week after the first visit to evaluate the test-retest reliability. Construct validity was evaluated by examining the associations between the scores on the SAS and the scores obtained from the SPADI, SF-36, and age of the patients. To assess responsiveness, data were collected in the first visit and then again after 4 weeks physiotherapy intervention. Test-retest reliability and internal consistency were assessed using Intra-class Correlation Coefficient (ICC) and Cronbach's alpha, respectively. To evaluate construct validity, Spearman's rank correlation was used. The ability of the SAS to detect changes was evaluated by the receiver-operating characteristics method. No problem or language difficulties were reported during translation process. Test-retest reliability of the SAS was excellent with an ICC of 0.98. Also, the marginal Cronbach's alpha level of 0.64 was obtained. The correlation between the SAS and the SPADI was low, proving divergent validity, whereas the correlations between the SAS and the SF-36/age were moderate proving convergent validity. A marginally acceptable responsiveness was achieved for the Persian SAS. The study provides some evidences to support the test-retest reliability, internal consistency, construct validity, and responsiveness of the Persian version of the SAS in patients with shoulder disorders. Therefore, it seems that this instrument is a useful measure of shoulder activity level in research setting and clinical practice

In this study, mitochondrial DNA analysis using 16S ribosomal DNA (rDNA) was performed to investigate the phylogeny relationship of Trichiurus lepturus in the Persian Gulf compared to the other investigated area. The amplification of 16S rDNA resulted in a product of 600 bp in all samples. The results showed that the isolated strain belongs to T. lepturus showing 42 divergence sites among the same reported partial sequences of 16S rRNA gene from the other area (West Atlantic and Indo-Pacific area). Phylogeny results showed that all 18 haplotypes of the species clustered into five clades with reasonably high bootstrap support of values (>64%). Overall, the tree topology for both phylogenetic and phenetic trees for 16S rDNA was similar. Both trees exposed two major clusters, one wholly containing the haplotypes of the T. lepturus species belonging to Indo-Pacific area with two major sister groups including Persian Gulf specimen and the other cleared the Western Atlantic and Japan individuals clustered in another distinct clade supporting the differentiation between the two areas. Phylogenic relationship observed between the Persian Gulf and the other Indo-Pacific Individuals suggested homogeneity between two mentioned areas. PMID:27822250

This study aimed to determine intraocular pressure (IOP) and central corneal thickness (CCT) measurements in healthy Persian children to find clinical reference values in this ethnicity. Additionally, we examined the possible relationship between these measurements. This cross-sectional study included 262 eyes of 131 Persian primary school children between 6 and 13 years of age. All eyes were healthy and had no anterior or posterior segment abnormalities, corneal disease, or evidence of glaucoma. Specular microscopy was used to measure CCT and both noncontact tonometry (NCT) and Goldmann applanation tonometer (GAT) were used to measure IOP. Correlations between IOP measurements were also examined. Mean CCT was 513.47 ± 34.51 μm in the right eye (OD) and 513.93 ± 33.88 μm in the left eye (OS). The CCT was not significantly different between older (10-13 years) and younger (6-9 years) patients. Mean IOP measured with GAT was 13.86 ± 2.13 mmHg OD and 13.72 ± 2.04 mmHg OS and mean IOP measured with NCT was 15.26 ± 2.38 mmHg OD and 15.11 ± 2.18 mmHg OS. The IOP and CCT measured with GAT were weakly correlated (OD: r = 0.141, P = 0.114; OS: r = 0.236, P = 0.007). However, IOP and CCT measured with NCT (OD: r = 0.487, P = 0.000; OS: r = 0.456, P = 0.000) were moderately correlated. Our outcomes demonstrated that for 100 μm increase in CCT, IOP measured with GAT and NCT increased by 0.8 and 3.3 mmHg, respectively, in OD and by 1.4 and 2.9 mmHg in OS. Based on intraclass correlation coefficients, IOP measurements made with GAT and NCT were in fair agreement in OD and in good agreement in OS. The IOP and CCT in healthy Persian school children (6-13 years old) were positively correlated. Our findings revealed that corneal thickness is thinner in Persian children than in most other racial groups.

Bulb color is an important consumer trait for onion (Allium cepa L., Allioideae, Asparagales). The bulbs accumulate a range of flavonoid compounds, including anthocyanins (red), flavonols (pale yellow), and chalcones (bright yellow). Flavonoid regulation is poorly characterized in onion and in other plants belonging to the Asparagales, despite being a major plant order containing many important crop and ornamental species. R2R3-MYB transcription factors associated with the regulation of distinct branches of the flavonoid pathway were isolated from onion. These belonged to sub-groups (SGs) that commonly activate anthocyanin (SG6, MYB1) or flavonol (SG7, MYB29) production, or repress phenylpropanoid/flavonoid synthesis (SG4, MYB4, MYB5). MYB1 was demonstrated to be a positive regulator of anthocyanin biosynthesis by the induction of anthocyanin production in onion tissue when transiently overexpressed and by reduction of pigmentation when transiently repressed via RNAi. Furthermore, ectopic red pigmentation was observed in garlic (Allium sativum L.) plants stably transformed with a construct for co-overexpression of MYB1 and a bHLH partner. MYB1 also was able to complement the acyanic petal phenotype of a defined R2R3-MYB anthocyanin mutant in Antirrhinum majus of the asterid clade of eudicots. The availability of sequence information for flavonoid-related MYBs from onion enabled phylogenetic groupings to be determined across monocotyledonous and dicotyledonous species, including the identification of characteristic amino acid motifs. This analysis suggests that divergent evolution of the R2R3-MYB family has occurred between Poaceae/Orchidaceae and Allioideae species. The DNA sequences identified will be valuable for future analysis of classical flavonoid genetic loci in Allium crops and will assist the breeding of these important crop species. PMID:28018399

Atrazine is a wide-range herbicide. For over 50 years, atrazine has been used as a selective broadleaf herbicide in many capacities, from pre-plant to pre-emergence to post-emergence, depending on the crop and application. Currently, 96% of all atrazine used is for commercial applications in fields for the control of broadleaf and grassy weeds in crops such as sorghum, corn, sugarcane, pineapple and for the control of undesirable weeds in rangeland. Many panhandle wells have also detected atrazine in samples taken. The concern for the public is the long-term effect of atrazine with its increasing popularity, and the impact on public health. We investigated the effect of different concentrations of atrazine on Allium cepa (onion), a standard plant test system. We established a control with the Allium bulbs grown on hydroponics culture. Varying concentrations of atrazine was used on the standard plant test system, Allium cepa grown hydroponically. The mitotic indices varied and with higher doses, we observed various chromosomal abnormalities including sticky bridges, early and late separations, and lag chromosomes with higher doses of treatments. In the second part of the experiment, 0.1ppb, 1ppb, 10ppb, and 100ppb concentrations of atrazine were applied to established phytoplankton cultures from the Lake Tanglewood, Texas. Study with a Sedgwick-Rafter counter, a BX-40 Olympus microscope with DP-70 camera revealed a gradual shift in the phytoplankton community from obligatory to facultative autotroph and finally to a parasitic planktonic community. This explains the periodic fish kill in the lakes after applications of atrazine in crop fields.

Efficacy of bioassays of "aberrant cells frequency" and "proliferative activity" in root meristem of Allium cepa L. is studied in the present work for a cyto- and genotoxicity assessment of natural waters contaminated with 90Sr and heavy metals in the vicinity of the radioactive waste storage facility in Obninsk, Kaluga region. The Allium-test is shown to be applicable for the diagnostics of environmental media at their combined pollution with chemical and radioactive substances. The analysis of aberration spectrum shows an important role of chemical toxicants in the mutagenic potential of waters collected in the vicinity of the radioactive waste storage facility. Biological effects are not always possible to explain from the knowledge on water contamination levels, which shows limitations of physical-chemical monitoring in providing the adequate risk assessment for human and biota from multicomponent environmental impacts.

Background Treatment motivation has always been an important issue in substance abuse treatment. In recent decades, several instruments have been developed to measure this concept. Objectives In this study, cultural adaptation and psychometric properties of the Persian version of the circumstances, motivation and readiness scale (CMR) are illustrated in a sample of Iranian addicts. Materials and Methods The translation process followed Beaton et al.’s (2000) guideline for the cross-cultural adaptation of self-administered questionnaires, including the steps of translation, synthesis, back translation, expert committee review, and pre-testing. The final version of the Persian CMR was assessed for internal consistency and construct validity (n = 203). Results There was one eliminated item in the cross-cultural adaptation process. Also, four items that had low correlation with the total score were excluded from the questionnaire during the initial analysis. Using the remaining items, Principle axis factoring with Promax rotation was performed and three factors, circumstance, motivation, and readiness, were identified. The secondary order three factor model provided a good statistical and conceptual fit for the data. Internal consistency met the criterion for a reliable measure (Cronbach’s alpha = 0.840). The α range for these identified factors was 0.597 to 0.837. Conclusions Although the CMR was originally designed for use in TC treatment, this study suggests that it is also applicable, with some modifications, in short-term residential camps. Also, it is concluded that the Persian translation of the CMR can be applied for studies among Persian addicts. PMID:27622165

Inflammatory bowel diseases (IBD) are a group of inflammatory conditions of the colon and small intestine that may have critical consequences on patient's quality of life (QOL). Many disease-specific QOL tools have been developed recently. The McMaster Inflammatory Bowel Disease Questionnaire (IBDQ) is one of them. The aim of this study was to translate the IBDQ from English to Persian and evaluate the validity and reliability of this version of the McMaster IBDQ. 68 subjects with ulcerative colitis were recruited in this study. The original IBDQ was translated into Persian using back- translation method. The reliability of the subscales and the summary score of the Persian IBDQ was demonstrated by intraclass correlation coefficients, their validity was evaluated by their correlations with SF-36, visual analogue scale and colitis activity index. All dimensions of IBDQ met the standards of construct validity and were correlated well with SF-36, visual analog scale and colitis activity index. IBDQ was able to discriminate the different groups of patients. The intraclass correlation coefficient was very high and its value was close to one (P<0.05). All dimensional scores differed significantly between the baseline and the follow-up measurement. The findings of this study conclude that the Persian translation of IBDQ confers satisfactory psychometric and cultural properties when applied to a sample of Iranian population with inflammatory bowel disease. This questionnaire is recommended for use in clinical trials and in the assessment of efficacy of interventions and therapy.

Evaluation is the main component in design and implementation of educational activities and rapid growth of educational institution programs. Outpatient medical education and clinical training environment is one of the most important parts of training of medical residents. This study aimed to determine the validity and reliability of the Persian version of Ambulatory Care Learning Educational Environment Measure (ACLEEM) questionnaire, as an instrument for assessment of educational environments in residency medical clinics. This study was performed on 180 residents in Shiraz University of Medical Sciences, Shiraz, Iran, in 2014-2015. The questionnaire designers' electronic permission (by email) and the residents' verbal consent were obtained before distributing the questionnaires. The study data were gathered using ACLEEM questionnaire developed by Arnoldo Riquelme in 2013. The data were analyzed using the SPSS statistical software, version 14, and MedCalc ® software. Then, the construct validity, including convergent and discriminant validities, of the Persian version of ACLEEM questionnaire was assessed. Its internal consistency was also checked by Cronbach's alpha coefficient. Five team members who were experts in medical education were consulted to test the cultural adaptation, linguistic equivalency, and content validity of the Persian version of the questionnaire. Content validity indexes were >0.9 in all items. In factor analysis of the instrument, the Kaiser-Meyer-Olkin index was 0.928 and Barlett's sphericity test yielded the following results: X 2 =6,717.551, df =1,225, and P ≤0.001. Besides, Cronbach's alpha coefficient of ACLEEM questionnaire was 0.964. Cronbach's alpha coefficients were also >0.80 in all the three domains of the questionnaire. Overall, the Persian version of ACLEEM showed excellent convergent validity and acceptable discriminant validity, except for the clinical training domain. According to the results, the Persian version of

The role of the sand in chemical warfare agent exposure among Persian Gulf War veterans: Al Eskan disease and "dirty dust".

The purpose of this paper is to inquire into the relationship between Al Eskan disease and the probable exposure to chemical warfare agents by Persian Gulf War veterans. Al Eskan disease, first reported in 1991, compromises the body's immunological defense and is a result of the pathogenic properties of the extremely fine, dusty sand located in the central and eastern region of the Arabian peninsula. The disease manifests with localized expression of multisystem disorder. Signs and symptoms of Al Eskan disease have been termed by the news media "Persian Gulf syndrome." The dust becomes a warfare agent when toxic chemicals are microimpregnated into inert particles. The "dirty dust" concept, that the toxicity of an agent could be enhanced by absorption into inactive particles, dates from World War I. A growing body of evidence shows that coalition forces have encountered Iraqi chemical warfare in the theater of operation/Persian Gulf War to a much greater extent than early U.S. Department of Defense information had indicated. Veterans of that war were exposed to chemical warfare agents in the form of direct (deliberate) attacks by chemical weapons, such as missiles and mines, and indirect (accidental) contamination from demolished munition production plants and storage areas, or otherwise. We conclude that the microimpregnated sand particles in the theater of operation/Persian Gulf War depleted the immune system and simultaneously acted as vehicles for low-intensity exposure to chemical warfare agents and had a modifying-intensifying effect on the toxicity of exposed individuals. We recommend recognition of a new term, "dirty sand," as a subcategory of dirty dust/dusty chemical warfare agents. Our ongoing research efforts to investigate the health impact of chemical warfare agent exposure among Persian Gulf War veterans suggest that Al Eskan disease is a plausible and preeminent explanation for the preponderance of Persian Gulf War illnesses.

Currently, only 31 nereidid species are known from the Persian Gulf and Gulf of Oman. The present study was carried out in order to investigate the poorly known diversity of nereidid polychaetes from seas of the southern coasts of Iran. Specimens were collected from 23 locations along the intertidal zones of the two water bodies. Among the 26 species found: two are new, and are described here, including Simplisetia qeshmensis sp. nov. and Neanthes biparagnatha sp. nov.; 11 are new geographical records. Neanthes biparagnatha sp. nov. is most similar to N. deplanata (Mohammed, 1971), which is also found in the Persian Gulf, but can be most easily distinguished from it by the presence of bars in addition to cones in Area IV of the pharynx. Simplisetia qeshmensis sp. nov. may be distinguished from its closest congener, S. erythraeensis (Fauvel, 1918), also reported from the Persian Gulf, by having a greater number of paragnaths in Area I of the pharynx, an additional type of chaeta (homogomph spinigers) in the ventral neuropodial fascicle and having a reduced notopodial lobe in posterior chaetigers. The list of new records includes: one species from both areas, Neanthes glandicincta (Southern, 1921); eight species from the Persian Gulf, Leonnates decipiens Fauvel, 1929, Neanthes acuminata (Ehlers, 1868), Neanthes sp., Neanthes sp. cf. N. acuminata, Nereis sp. cf. N. pelagica Linnaeus, 1758, Perinereis cultrifera (Grube, 1840) species complex., Pseudonereis trimaculata (Horst, 1924), Pseudonereis sp. cf. P. variegata (Grube, 1857) and two from the Gulf of Oman, Leonnates persicus Wesenberg-Lund, 1949 and Perinereis kuwaitensis Mohammed, 1970. The present study brings to 40 the number of nereidid species currently known from the Persian Gulf and Gulf of Oman. A taxonomic key to nereidid species from the intertidal zones of the Persian Gulf and Gulf of Oman is presented to facilitate future investigations.

ABSTRACT Allium white rot (AWR) is a serious disease of Allium spp. caused by the sclerotium-forming fungus Sclerotium cepivorum. This work has examined the effects of onion waste compost (OWC) and spent mushroom compost (SMC), with and without Trichoderma viride S17A, on sclerotia viability and AWR in glasshouse and field experiments. Incorporation of OWC into soil reduced the viability of sclerotia and the incidence of AWR on onion plants in glasshouse pot bioassays, whereas SMC or T. viride S17A only reduced incidence of AWR. In two field trials, OWC reduced sclerotia viability and was as effective in reducing AWR as a fungicide (Folicur, a.i. tebuconazole). Field application of SMC had no effect on sclerotia viability and did not control AWR. However, the addition of T. viride S17A to SMC facilitated proliferation of T. viride S17A in the soil and increased the healthy onion bulb yield. The results indicate two mechanisms for the suppression of AWR: (i) reduction in the soil population of viable sclerotia, which may be due to volatile sulfur compounds detected in OWC but absent in SMC, and (ii) prevention of infection of onion plants from sclerotia following amendment of soil with OWC, SMC, or T. viride S17A.

Objective: Limited research has examined the psychometric properties of death depression scales in Persian populations with cardiac disease despite the need for valid assessment tools for evaluating depressive symptoms in patients with life-limiting chronic conditions. The present study aimed at evaluating the reliability and validity of the Persian Version of Death Depression Scale - Revised (DDS-R) in Iranian patients who had recent acute myocardial infarction (AMI). Method: This psychometric study was conducted with a convenience sample of 407 patients with AMI diagnosis who completed the Persian version of the DDS-R. The face, content, and construct validity of the scale were ascertained. Internal consistency, test-retest, and construct reliability (CR) were used to assess reliability of the Persian Version of DDS-R. Results: Based on maximum likelihood exploratory factor analysis and consideration of conceptual meaning, a 4-factor solution was identified, explaining 75.89% of the total variance. Goodness-of-fit indices (GFI), Comparative Fit Index (CFI), Normed Fit Index (NFI), Incremental Fit Index (IFI), and Root Mean Square Error of Approximation (RMSEA) in the final DDS-R structure demonstrated the adequacy of the 4-domain structure. The internal consistency, construct reliability, and Intra-class Correlation Coefficients (ICC) were greater than .70. Conclusion: The DDS-R was found to be a valid and reliable assessment tool for evaluating death depression symptoms in Iranian patients with AMI.

Background: Allium victorialis var. platyphyllum is an edible perennial herb and has been used as a vegetable or as a Korean traditional medicine. Allium species have received much attention owing to their diverse pharmacological properties, including antioxidative, anti-inflammatory, and anticancer activities. However, A. victorialis var. platyphyllum needs more study. Methods: The chemopreventive potential of A. victorialis var. platyphyllum methanol extracts was examined by measuring 12-O-tetra-decanoylphorbol 13-acetate (TPA)-induced superoxide anion production in the differentiated HL-60 cells, TPA-induced mouse ear edema, and Ames/Salmonella mutagenicity. The apoptosis-inducing capabilities of the extracts were evaluated by the 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2H-tetrazolium bromide assay, 4’,6-diamidino-2-phenylindole staining, and the DNA fragmentation assay in human colon cancer HT-29 cells. Antimetastatic activities of the extracts were also investigated in an experimental mouse lung metastasis model. Results: The methanol extracts of A. victorialis var. platyphyllum rhizome (AVP-R) and A. victorialis var. platyphyllum stem (AVP-S) dose-dependently inhibited the TPA-induced generation of superoxide anion in HL-60 cells and TPA-induced ear edema in mice, as well as 7,12-dimethylbenz[a]anthracene (DMBA) and tert-butyl hydroperoxide (t-BOOH) -induced bacterial mutagenesis. AVP-R and AVP-S reduced cell viability in a dose-related manner and induced apoptotic morphological changes and internucleosomal DNA fragmentation in HT-29 cells. In the experimental mouse lung metastasis model, the formation of tumor nodules in lung tissue was significantly inhibited by the treatment of the extracts. Conclusions: AVP-R and AVP-S possess antioxidative, anti-inflammatory, antimutagenic, proapoptotic, and antimetastatic activities. Therefore, these extracts can serve as a beneficial supplement for the prevention and treatment of cancer. PMID:25337587

This study identified chemical and environmental exposures specifically associated with the 1991 Persian Gulf War. Exposures were self-reported in a postal questionnaire, in the period of 2000-2002, by 1,424 Australian male Persian Gulf War veterans in relation to their 1991 Persian Gulf War deployment and by 625 Persian Gulf War veterans and 514 members of a military comparison group in relation to other active deployments. Six of 28 investigated exposures were experienced more frequently during the Persian Gulf War than during other deployments; these were exposure to smoke (odds ratio [OR], 4.4; 95% confidence interval, 3.0-6.6), exposure to dust (OR, 3.7; 95% confidence interval, 2.6-5.3), exposure to chemical warfare agents (OR, 3.9; 95% confidence interval, 2.1-7.9), use of respiratory protective equipment (OR, 13.6; 95% confidence interval, 7.6-26.8), use of nuclear, chemical, and biological protective suits (OR, 8.9; 95% confidence interval, 5.4-15.4), and entering/inspecting enemy equipment (OR, 3.1; 95% confidence interval, 2.1-4.8). Other chemical and environmental exposures were not specific to the Persian Gulf War deployment but were also reported in relation to other deployments. The number of exposures reported was related to service type and number of deployments but not to age or rank.

The present study aimed to translate and evaluate the reliability and validity of the Persian version of the 11-item Intermittent and Constant Osteoarthritis Pain (ICOAP) measure in Iranian subjects with Knee Osteoarthritis (KOA). The ICOAP questionnaire was translated according to the Manufacturers Alliance for Productivity and Innovation (MAPI) protocol. The procedure consisted of forward and backward translation, as well as the assessment of the psychometric properties of the Persian version of the questionnaire. A sample of 230 subjects with KOA was asked to complete the Persian versions of ICOAP and Knee injury and Osteoarthritis Outcome Score (KOOS). The ICOAP was readministered to forty subjects five days after the first visit. Test-retest reliability was assessed using Intraclass Correlation Coefficient (ICC), and internal consistency was assessed by Cronbach's alpha and item-total correlation. The correlation between ICOAP and KOOS was determined using Spearman's correlation coefficient. Subjects found the Persian-version of the ICOAP to be clear, simple, and unambiguous, confirming its face validity. Spearman correlations between ICOAP total and subscale scores with KOOS scores were between 0.5 and 0.7, confirming construct validity. Cronbach's alpha, used to assess internal consistency, was 0.89, 0.93, and 0.92 for constant pain, intermittent pain, and total pain scores, respectively. The ICC was 0.90 for constant pain and 0.91 for the intermittent pain and total pain score. The Persian version of the ICOAP is a reliable and valid outcome measure that can be used in Iranian subjects with KOA.

To translate, culturally adapt, and validate the simple shoulder test (SST) and Oxford Shoulder Score (OSS) into Persian language using a cross-sectional and prospective cohort design. A standard forward and backward translation was followed to culturally adapt the SST and the OSS into Persian language. Psychometric properties of floor and ceiling effects, construct convergent validity, discriminant validity, internal consistency reliability, test-retest reliability, standard error of the measurement (SEM), smallest detectable change (SDC), and factor structure were determined. One hundred patients with shoulder disorders and 50 healthy subjects participated in the study. The PSST and the POSS showed no missing responses. No floor or ceiling effects were observed. Both the PSST and POSS detected differences between patients and healthy subjects supporting their discriminant validity. Construct convergent validity was confirmed by a very good correlation between the PSST and POSS (r = 0.68). There was high internal consistency for both the PSST (α = 0.73) and the POSS (α = 0.91 and 0.92). Test-retest reliability with 1-week interval was excellent (ICCagreement = 0.94 for PSST and 0.90 for POSS). Factor analyses demonstrated a three-factor solution for the PSST (49.7 % of variance) and a two-factor solution for the POSS (61.6 % of variance). The SEM/SDC was satisfactory for PSST (5.5/15.3) and POSS (6.8/18.8). The PSST and POSS are valid and reliable outcome measures for assessing functional limitations in Persian-speaking patients with shoulder disorders.

Introduction: To evaluate the reliability, validity and feasibility of the Persian version of the Pediatric Quality of Life inventory (PedsQL™ 4.0™ 4.0) Generic Core Scales in Iranian healthy students ages 7-15 and chronically ill children ages 2-18. Methods: We followed the translation methodology proposed by developer to validate Persian version of PedsQL™ 4.0™ 4.0 Generic Core Scales for children. Six hundred and sixty children and adolescents and their parents were enrolled. Sample of 160 healthy students were chosen by random cluster method between 4 regions of Isfahan education offices and 60 chronically ill children were recruited from St. Alzahra hospital private clinics. The questionnaires were fulfilled by the participants. Results: The Persian version of PedsQL™ 4.0™ 4.0 Generic Core Scales discriminated between healthy and chronically ill children (healthy students mean score was 12.3 better than chronically ill children, P<0.001). Cronbachs’ alpha internal consistency values exceeded 0.7 for children self reports and proxy reports of children 5-7 years old and 13-18 years old. Reliability of proxy reports for 2-4 years old was much lower than 0.7. Although, proxy reports for chronically ill children 8-12 years old was more than 0.7, these reports for healthy children with same age group was slightly lower than 0.7. Constructive, criterion face and content validity were acceptable. In addition, the Persian version of PedsQL™ 4.0™ 4.0 Generic Core Scales was feasible and easy to complete. Conclusion: Results showed that Persian version of PedsQL™ 4.0™ 4.0 Generic Core Scales is valid and acceptable for pediatric health researches. It is necessary to alternate scoring for 2-4 years old questionnaire and to find a way to increase reliability for healthy children aged 8-12 years especially, according to Iranian culture.

Among various neurological disorders, multiple sclerosis (MS) is an expanding global immune- related inflammatory disease with complex etiologies. There is increasing demand for the use and administration of natural medicaments for this disorder. Traditional Persian Medicine (TPM) is a school of medicine and a medicinal plants-based resource for clinical studies put forward by Persian scholars. This paper aims to gather and study the effectiveness of all medicinal plants from the most popular Persian pharmacopeias. Five main Persian pharmacopeias from the 9th to the 18th century A.D. have been studied to identify the remedial plants for this disorder. Moreover, PubMed, and Scopus databases have been checked to derive relevant activities for these plants. Khaddar (numbness), Esterkha (Palsy) and Falej (quadriplegia) are traditional definitions; these are clinically close to what is known as MS in today's medicine. In all, 118 medicinal plants, related to 65 families, have been authenticated out of 157 chosen medicaments. Apiaceae is the most frequent family (13 reports). Fruits and roots of plants have been the most reported botanical parts (34 and 32 items). The employed routes of administration are topical, oral, or a combination of the two (27, 57, and 34 sequentially). Fifteen medicines have been reported for Khaddar, Esterkha, and Falej simultaneously. Antioxidant activities, immunomodulatory, and anti-inflammatory properties of medicines are known as some main mechanisms to manage MS. These functions are possessed by 81%, 36%, and 48% of the studied plants, respectively. Hence, conducting adducible clinical trials and highly approved experimental tests on animals may lead to novel drugs with lesser undesirable and much more therapeutic effects on controlling MS.

1987-08-01

The Rosenberg Self-esteem scale was translated into Persian and 12 Iranian bilingual judges confirmed the soundness of translation. The psychometric properties of the Persian version of Rosenberg Self-esteem Scale were studied in two samples of Iranian college students separately. Sample I consisted of 232 Iranian students in American universities, and Sample II comprised 305 Iranian students in Iranian universities. Criterion measures of loneliness, depression, anxiety, neuroticism, psychoticism, misanthropy, locus of control, tendency to dissimulate, and measures of relationship with parents, peers, and academic achievement were obtained. Item-total score correlations and alpha reliabilities supported the internal consistency of the scale. Test-retest reliabilities indicated the stability of the scores, and correlations between scores of the scale, and criterion measures supported the concurrent validity of the Rosenberg scale. Factor analysis of the Rosenberg scores confirmed the unidimensionality of the scale.

The clinical competence of nursing students in operating room (OR) is an important issue in nursing education. The purpose of this study was to evaluate the psychometric properties of the Persian Perceived Perioperative Competence Scale-Revised (PPCS-R) instrument. This cross-sectional study was conducted across 12 universities in Iran. The psychometric properties and factor structure of the PPCS-R for OR students was examined. Based on the results of factor analysis, seven items were removed from the original version of the scale. The fitness indices of the Persian scale include comparative fit index (CFI) = .90, goodness-of-fit-index (GFI) = .86, adjusted goodness-of-fit index (AGFI) = .90, normed fit index (NFI) = .84, and root mean square error of approximation (RMSEA) = .04. High validity and reliability indicated the scale's value for measuring perceived perioperative competence of Iranian OR students.

The relationship between identity processing styles and language proficiency in English as foreign language (EFL) was investigated among the Persian EFL learners. 266 Persian candidates taking part in a Ph.D. examination at Shiraz University took part. The Language Proficiency Test was used to measure language proficiency in English. The Identity Styles Inventory was used to measure normative, informational, and diffuse-avoidant identity processing styles. Relationships between normative and informational styles and language proficiency and its subscales (grammar, vocabulary, and reading) were positive and significant. Negative relationships between diffuse-avoidant style and language proficiency and its subscales (grammar, vocabulary, and reading) were observed. There were significant sex differences for diffuse-avoidant style and for vocabulary.

Validation of 2 self-report questionnaires. To evaluate the internal consistency, reliability, and construct validity of the Persian versions of the fear avoidance beliefs questionnaire (FABQ) and the Tampa Scale of Kinesiophobia (TSK) in patients with acute and chronic neck pain. The FABQ and TSK are 2 important measures to evaluate fear of pain and fear avoidance beliefs in patients with spinal pain. To date, the psychometric properties of these questionnaires have not been demonstrated in Persian-speaking patients with neck pain in Iran. One hundred sixty-six patients with acute and chronic neck pain participated in the study. The construct validity of the questionnaires was evaluated by measuring convergent and known-groups validity. The visual analogue scale measure of pain, neck disability index, hospital anxiety and depression scale, and the physical (PCS-12) and mental (MCS-12) summary scores of the Short Form health survey (SF-12) were used to test construct validity of the Persian FABQ and TSK. In addition, 50 randomly selected patients with chronic neck pain were asked to complete the questionnaires 48 hours later for the second time. Cronbach α coefficient for the FABQ and TSK in patients with acute and chronic pain was in the range from 0.77 to 0.92 and 0.77 to 0.78, respectively. The Persian FABQ and TSK showed satisfactory test-retest reliability with intraclass correlation coefficient of more than 0.80. There were moderate to strong correlations between the Persian FABQ and TSK scores and the neck disability index (r = 0.44-0.55), Depression subscales of the hospital anxiety and depression scale (r = 0.42-0.48), and PCS-12 (r =-0.34 to -0.62). The Persian FABQ and TSK have acceptable reliability and validity for measuring pain related fear and avoidance beliefs among Persian-speaking patients with acute and chronic neck pain. However, considering the study limitations, the findings should be interpreted with caution. 3.

Micropropagation and cryopreservation of garlic (Allium sativum L.).

PubMed

Keller, E R Joachim; Senula, Angelika

2013-01-01

Garlic (Allium sativum L.) is a very important medicinal and spice plant. It is conventionally propagated by daughter bulbs ("cloves") and bulbils from the flower head. Micropropagation is used for speeding up the vegetative propagation mainly using the advantage to produce higher numbers of healthy plants free of viruses, which have higher yield than infected material. Using primary explants from bulbs and/or bulbils (shoot tips) or unripe inflorescence bases, in vitro cultures are initiated on MS-based media containing auxins, e.g., naphthalene acetic acid, and cytokinins, e.g., 6-γ-γ-(dimethylallylaminopurine) (2iP). Rooting is accompanying leaf formation. It does not need special culture phases. The main micropropagation methods rely on growth of already formed meristems. Long-term storage of micropropagated material, cryopreservation, is well-developed to maintain germplasm. The main method is vitrification using the cryoprotectant mixture PVS3.

Military nursing service during wartime represents significant contributions to a unique type of health care. The purposes of this study were to: (1) generate themes that elucidate combat nursing experiences, (2) honor nurses who served by sharing their stories, and (3) permanently archive accounts of nursing personnel who served during the Persian Gulf Wars during the late 20th and early 21st centuries. Eleven military nurses who provided health care to American troops in the Persian Gulf participated in a historical study as part of the ongoing Nurses at War oral history project documenting the experiences of nurses during times of armed conflict. The overriding theme, "It's what we're here for," demonstrates the commitment of nurses: a commitment to care and to sacrifice. Other themes drawn from the study included lessons learned from their wartime nursing experiences, sacrifices made, and chronicles of caring. During armed conflict in the Persian Gulf Wars, military nurses' personal stories demonstrated the importance of being engaged in making meaningful professional and historical contributions. These nurses displayed professional commitment and hardiness in the face of difficult life circumstances, saying, "We did what we had to do."

Observation of dipropenyldisulfide and other organic sulfur compounds in the atmosphere of a beech forest with Allium ursinum ground cover

Puxbaum, H.; König, G.

Dipropenyldisulfide, methylpropenyldisulfide, cis-propenylpropyldisulfide, diallylsulfide, dimethyldisulfide and 3-methylthiopropene were detected in the atmosphere of a beech forest with Allium ursinum (broad-leaved garlic) ground cover plants. Furthermore, it was shown that the Allium plants were the source of the organic sulfur compounds. The atmospheric concentrations of the organic sulfur observed on one day in May 1994 in a suburban forest in Vienna ranged from 0.3 to 7.8 ppb S with an average level of 2.9 ppb S. The atmospheric emission rate of organic sulfur species from A. ursinum determined with an enclosure box was the highest ever reported for terrestrial continental plants. The total organic sulfur flux on the average was at least 1 jug g-1h-1 (plant dry weight) or 60 gmgm-2 h-1 (per unit of ground area).

The effect of Persian and almond gums (0, 0.1 and 0.2% (w/w)) as fat replacers and milk fat (0.4, 0.9, and 1.4% (w/w)) on physicochemical and rheological characteristics and microstructure of low-fat Iranian White cheese was studied. Persian and almond gums both effectively increased moisture-to-protein (M:P) ratio of low-fat cheese samples which in turn led to a significant reduction in the hardness parameters fracture stress and Young's and storage (G') moduli ( p  < .05); however, the effect of Persian gum was more pronounced ( p  < .01). Gum addition promoted cheese yield and proteolysis rate ( p  < .05). Response surface optimization described that supplementation of cheese milk containing 0.9% fat with 0.2% Persian gum and 0.12% almond gum would result in a low-fat cheese with textural properties similar to its full-fat counterpart. Scanning electron microscopy revealed that the fat replacers produced full-fat-like structure in the low-fat Iranian White cheese, when incorporated at the optimum levels.

2017-02-01

This study aimed to examine the diagnostic accuracy of a non-word repetition (NWR) test in identifying Persian-speaking preschool children with specific/primary language impairment (PLI). Children with PLI show consistently poorer performance in non-word repetition tasks than their typically developing language (TDL) counterparts. It is assumed that the ability to repeat non-words triggers language skills and that the absence of this ability may be responsible for language impairment in PLI children. Twenty preschool children with PLI participated in this study and were compared with 31 peers whose language skills were developing typically. The TDL children were randomly selected from daycare centers, and the children with PLI were referred by qualified speech-language pathologists from speech therapy clinics. A Persian NWR test was administered and scored using two levels of scoring: item-level scoring and syllable-level scoring. Data were analyzed in two phases. The first phase aimed to determine any differences between the two groups of children in terms of NWR ability. The second phase examined the diagnostic measures of the test. The results of first phase documented that both scoring methods for the NWR test significantly differentiated between children with PLI and their normal peers. The second phase indicated that both scoring methods for the NWR test have good sensitivity and specificity in differentiating Persian-speaking children with PLI from their normal peers. Non-word repetition can be a reliable clinical marker of PLI in Persian-speaking preschool children. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

Prospective study. We aimed to validate the Persian version of the modified Oswestry disability questionnaire (MODQ) in patients with low back pain. Modified Oswestry low back pain disability questionnaire is a well-known condition-specific outcome measure that helps quantify disability in patients with lumbar syndromes. To test the validity in a pilot study, the Persian MODQ was administered to 25 individuals with low back pain. We then enrolled 200 consecutive patients with low back pain to fill the Persian MODQ as well as the short form 36 (SF-36) questionnaire. Convergent validity of the MODQ was tested using the Spearman's correlation coefficient between the MODQ and SF-36 subscales. Intraclass correlation coefficient (ICC) and Cronbach's α coefficient were measured to test the reliability between test and retest and internal consistency of all items, respectively. ICC for individual items ranged from 0.43 to 0.80 showing good reliability and reproducibility of each individual item. Cronbach's α coefficient was 0.69 showing good internal consistency across all 10 items of the Persian MODQ. Total MODQ score showed moderate to strong correlation with the eight subscales and the two domains of the SF-36. The highest correlation was between the MODQ and the physical functioning subscale of the SF-36 (r=-0.54, p<0.001) and the physical component domain of the SF-36 (r=-0.55, p<0.001) showing that MODQ is measuring what it is supposed to measure in terms of disability and physical function. Persian version of the MODQ is a valid and reliable tool for the assessment of the disability following low back pain.

In order to improve the ethical climate in health care organizations, it is important to apply a valid measure. This study aimed to investigate the psychometric properties of the Persian version of the Hospital Ethical Climate Survey (HECS) and to assess nurses’ perceptions of the ethical climate in teaching hospitals of Iran. A cross-sectional study of randomly selected nurses (n = 187) was conducted in three teaching general hospitals of Tehran, capital of Iran. Olson’s Hospital Ethical Climate Survey (HECS), a self-administered questionnaire, was used to assess the nurses’ perceptions of the hospital ethical climate. Descriptive statistics, confirmatory factor analysis (CFA), internal consistency, and correlation were used to analyze the data. CFA showed acceptable model fit: an standardized root mean square residual (SRMR) of 0.064, an non-normalized fit index (NNFI) of 0.96, a comparative fit index (CFI) of 0.96, and an root mean square error of approximation (RMSEA) of 0.075. The Cronbach’s alpha values were acceptable and ranging from 0.69 to 0.85. The overall Cronbach’s alpha coefficient was 0.94. The factor loadings for all ethical climate items were between 0.50 and 0.80, which revealed good structure of the Persian version of the HECS. Survey findings showed that the “managers” subscale had the highest score and the subscale of “doctors” had the lowest score. This study shows that the Persian version of the HECS is a valid and reliable instrument for measuring nurses’ perceptions of the ethical climate in hospitals of Iran PMID:25512834

Microplastics (MPs; <5 mm) in aquatic environments are an emerging contaminant of concern due to their possible ecological and biological consequences. This study addresses that MP quantification and morphology to assess the abundance, distribution, and polymer types in littoral surface sediments of the Persian Gulf were performed. A two-step method, with precautions taken to avoid possible airborne contamination, was applied to extract MPs from sediments collected at five sites during low tide. MPs were found in 80% of the samples. Across all sites, fiber particles were the most dominate shape (88%), followed by films (11.2%) and fragments (0.8%). There were significant differences in MP particle concentration between sampling sites (p value <0.05). The sediments with the highest numbers of MPs were from sites in the vicinity of highly populated centers and municipal effluent discharges. FTIR analysis showed that polyethylene (PE), nylon, and polyethylene terephthalate (PET) were the most abundant polymer types. More than half of the observed MPs (56%) were in the size category of 1-4.7 mm length, with the remaining particles (44%) being in the size range of 10 μm to <1 mm. Compared to literature data from other regions, intertidal sediments in the Persian Gulf cannot be characterized as a hot spot for MP pollution. The present study could, however, provide useful background information for further investigations and management policies to understand the sources, transport, and potential effects on marine life in the Persian Gulf.

In this study, 398 Iranian cancer patients completed the 15-item Templer's Death Anxiety Scale (TDAS). Tests of internal consistency, principal components analysis, and confirmatory factor analysis were conducted to assess the internal consistency and factorial validity of the Persian TDAS. The construct reliability statistic and average variance extracted were also calculated to measure construct reliability, convergent validity, and discriminant validity. Principal components analysis indicated a 3-component solution, which was generally supported in the confirmatory analysis. However, acceptable cutoffs for construct reliability, convergent validity, and discriminant validity were not fulfilled for the three subscales that were derived from the principal component analysis. This study demonstrated both the advantages and potential limitations of using the TDAS with Persian-speaking cancer patients.

Purpose Evaluation is the main component in design and implementation of educational activities and rapid growth of educational institution programs. Outpatient medical education and clinical training environment is one of the most important parts of training of medical residents. This study aimed to determine the validity and reliability of the Persian version of Ambulatory Care Learning Educational Environment Measure (ACLEEM) questionnaire, as an instrument for assessment of educational environments in residency medical clinics. Materials and methods This study was performed on 180 residents in Shiraz University of Medical Sciences, Shiraz, Iran, in 2014–2015. The questionnaire designers’ electronic permission (by email) and the residents’ verbal consent were obtained before distributing the questionnaires. The study data were gathered using ACLEEM questionnaire developed by Arnoldo Riquelme in 2013. The data were analyzed using the SPSS statistical software, version 14, and MedCalc® software. Then, the construct validity, including convergent and discriminant validities, of the Persian version of ACLEEM questionnaire was assessed. Its internal consistency was also checked by Cronbach’s alpha coefficient. Results Five team members who were experts in medical education were consulted to test the cultural adaptation, linguistic equivalency, and content validity of the Persian version of the questionnaire. Content validity indexes were >0.9 in all items. In factor analysis of the instrument, the Kaiser–Meyer–Olkin index was 0.928 and Barlett’s sphericity test yielded the following results: X2=6,717.551, df =1,225, and P≤0.001. Besides, Cronbach’s alpha coefficient of ACLEEM questionnaire was 0.964. Cronbach’s alpha coefficients were also >0.80 in all the three domains of the questionnaire. Overall, the Persian version of ACLEEM showed excellent convergent validity and acceptable discriminant validity, except for the clinical training domain

The chemical composition of the essential oils of different Allium nigrum L. organs and the antibacterial activity were evaluated. The study is particularly interesting because hitherto there are no reports on the antibacterial screening of this species with specific chemical composition. Therefore, essential oils from different organs (flowers, stems, leaves and bulbs) obtained separately by hydrodistillation were analyzed using gas chromatography–mass spectrometry (GC–MS). The antibacterial activity was evaluated using the disc and microdilution assays. In total, 39 compounds, representing 90.8-96.9 % of the total oil composition, were identified. The major component was hexadecanoic acid (synonym: palmitic acid) in all the A. nigrum organs oils (39.1-77.2 %). We also noted the presence of some sesquiterpenes, mainly germacrene D (12.8 %) in leaves oil) and some aliphatic compounds such as n-octadecane (30.5 %) in bulbs oil. Isopentyl isovalerate, 14-oxy-α-muurolene and germacrene D were identified for the first time in the genus Allium L. All the essential oils exhibited antimicrobial activity, especially against Enterococcus faecalis and Staphylococcus aureus. The oil obtained from the leaves exhibited an interesting antibacterial activity, with a Minimum Inhibitory Concentration (MIC) of 62.50 µg/mL against these two latter strains. The findings showed that the studied oils have antibacterial activity, and thus great potential for their application in food preservation and natural health products. PMID:26417280

Background: Mucilage compounds are pharmaceutically important polysaccharides that have an extensive range of applications, including binding agents, thickeners, water retention agents, emulsion stabilizers, suspending agents, disintegrates, film formers, and gelling agents. A historical approach to medical science written by Iranian scholars could help in identifying excellent ideas and provide valuable information in this field for proper application. The aim of the current study was to introduce some mucilage uses derived from traditional Persian medicine (TPM). Methods: In this literature review, we assessed a few main traditional manuscripts of Iranian medicine, including the books Al Havi, Canon of Medicine, Qarabadine-kabir, Zakhireh-ye Khwarazm shahi, Tuhfat ul-Momineen and Makhzan-ul-Adwiah. The word “loab” in the aforementioned books were searched and all data about mucilage compounds were collected. Results: The use of medicinal plants containing mucilage in Iran dates back to ancient times. In traditional Persian manuscripts, mucilage is one of the most cited applications of medicinal plants for therapeutic objectives. There are various mucilage-producing plants in TPM such as Malva silvestris, Linum usitissimum, Althaea officinalis, Plantago psyllium, Descureania sophia and Ziziphus vulgaris. They have been used traditionally via oral or topical routes for respiratory, gastrointestinal, urinary, musculoskeletal, and genital systems as well as skin disorders. Certain applications are unique and promising for today’s chronic ailments. Conclusion: A scientific assessment of these valuable manuscripts would provide a better insight into the thoughts of the past sages and applicable for clinical use of the mucilage compounds. This may lead to research opportunities in the future. PMID:27516674

Background: Mucilage compounds are pharmaceutically important polysaccharides that have an extensive range of applications, including binding agents, thickeners, water retention agents, emulsion stabilizers, suspending agents, disintegrates, film formers, and gelling agents. A historical approach to medical science written by Iranian scholars could help in identifying excellent ideas and provide valuable information in this field for proper application. The aim of the current study was to introduce some mucilage uses derived from traditional Persian medicine (TPM). Methods: In this literature review, we assessed a few main traditional manuscripts of Iranian medicine, including the books Al Havi, Canon of Medicine, Qarabadine-kabir, Zakhireh-ye Khwarazm shahi, Tuhfat ul-Momineen and Makhzan-ul-Adwiah. The word “loab” in the aforementioned books were searched and all data about mucilage compounds were collected. Results: The use of medicinal plants containing mucilage in Iran dates back to ancient times. In traditional Persian manuscripts, mucilage is one of the most cited applications of medicinal plants for therapeutic objectives. There are various mucilage-producing plants in TPM such as Malva silvestris, Linum usitissimum, Althaea officinalis, Plantago psyllium, Descureania sophia and Ziziphus vulgaris.

Chronic pain needs to be evaluated with a standard instrument. The Brief Pain Inventory (BPI) is a pain assessment tool that has been validated in many languages. The aim of the present study was to develop the Persian version of the Brief Pain Inventory (BPI-P) and also to evaluate the psychometric properties of the BPI-P in the Iranian population. The BPI-P was translated from the original version of BPI using standard procedure. The Persian version of the BPI and 12-item Short-Form Health Survey (SF-12) were completed by 201 patients with chronic pain who were referred to a tertiary pain care clinic from 2013 to 2015. The performance status of the patients was evaluated by physicians using Eastern Cooperative Oncology Group performance test. Factor analysis of the BPI-P identified two scales: pain intensity and pain interference with life. These two factors explained 68.4% of the variance. Coefficient alpha values for BPI-P items ranging from 0.87 to 0.91 showed good internal consistency of the factors. The high intraclass correlation coefficients for the items of the questionnaire confirmed the test-retest reliability for the BPI-P. Patients with higher scores in Eastern Cooperative Oncology Group performance test reported higher levels of pain intensity and pain interference with life. Pain intensity in BPI-P correlated with physical functioning, bodily pain, mental health, and vitality of the SF-12 questionnaire, whereas pain interference was associated with general health, bodily pain, mental health, vitality, and social functioning. The present study demonstrated that the Persian version of the BPI could be a valid and reliable instrument for pain assessment in Persian-speaking patients.

To identify the ability of the Persian-version of the Shoulder Pain and Disability Index (SPADI) and the Disabilities of the Arm, Shoulder, and Hand (DASH) to detect changes in shoulder function following physiotherapy intervention (i.e. responsiveness) and to determine the change score that indicates a meaningful change in functional ability of the patient (i.e. Minimally Clinically Important Difference (MCID)). A convenient sample of 200 Persian-speaking patients with shoulder disorders completed the SPADI and the DASH at baseline and then again 4 weeks after physiotherapy intervention. Furthermore, patients were asked to rate their global rating of shoulder function at follow-up. The responsiveness was evaluated using two methods: the receiver operating characteristics (ROC) method and the correlation analysis. Two useful statistics extracted from the ROC method are the area under curve (AUC) and the optimal cutoff point called as MCID. Both the SPADI and the DASH showed the AUC of greater than 0.70 (AUC ranges = 0.77-0.82). The best cutoff points (or change scores) for the SPADI-total, SPADI-pain, SPADI-disability and the DASH were 14.88, 26.36, 23.86, and 25.41, respectively. Additionally, moderate to good correlations (Gamma = -0.51 to -0.58) were found between the changes in SPADI/DASH and changes in global rating scale. The Persian SPADI and DASH have adequate responsiveness to clinical changes in patients with shoulder disorders. Moreover, the MCIDs obtained in this study will help the clinicians and researchers to determine if a Persian-speaking patient with shoulder disorder has experienced a true change following a physiotherapy intervention. Implications for Rehabilitation Responsiveness was evaluated using two methods; the receiver operating characteristics (ROC) method and the correlation analysis. The Persian SPADI and DASH can be used as two responsive instruments in both clinical practice and research settings. The MCIDs of 14.88 and 25

During the 6-week-long 1991 Persian Gulf war, in which the civilian population was subjected to 18 separate missile attacks and the constant threat of nonconventional warfare, crude mortality rates in Israel were no higher than in the previous decade. Although the results are preliminary and need to undergo more sophisticated epidemiologic analysis, it appears that our population was able to tolerate the subacute period of psychological stress without excess mortality.

Although hysteria is associated largely with the nineteenth century, we find the subject treated in a tenth-century Persian medical text, the Hidayat al-Muta`allemin Fi al-Tibb [A Guide to Medical Learners] by al-Akhawayni Bukhari (d. 983 AD), a prominent physician in the Persian history of medicine. In this article, we discuss al-Akhawayni's views on seizure and hysteria and his differentiation between the two conditions, and we place it in a historical context.

This study aimed to assess the psychometric properties of the Persian version of the Ferrans and Powers 3.0 quality of life index (dialysis type) in patients receiving hemodialysis (HD) in order to describe their health-related quality of life (HRQOL). The sample (n = 150) consisted of adult HD patients receiving HD for at least 6 months from the establishment of the study. A total of 88 men and 62 women, with an average age of 50.47, from Shiraz, southern Iran, were enrolled in this study. The questionnaire was translated into Persian language using back translation and bilingual techniques. Convergent, discriminant, and construct validity of the Ferrans and Powers 3.0 dialysis version was evaluated. To check the internal consistency of the data, Cronbach's alpha, which indicates the reliability of the data, was used for the entire questionnaire and for the subscales. The convergent and discriminant validity and success scaling rate for both sexes were 100 %. Cronbach's alpha was 0.95 overall, which was greater than 0.7 for all the subscales except for the family subscale. Our results suggest that HD patients in southern Iran have higher HRQOL scores when compared with those in other countries. Despite the higher mean HRQOL score for men compared with women, men had significantly higher HRQOL scores only in the health and functioning subscale. There was no significant correlation between HD patients' HRQOL and educational level. The Persian version of Ferrans and Powers 3.0 has sufficient reliability and validity for measuring the quality of life of Persian-speaking HD patients. Female HD patients need more support and attention from family and society.

Background and aims The Bergen Social Media Addiction Scale (BSMAS), a six-item self-report scale that is a brief and effective psychometric instrument for assessing at-risk social media addiction on the Internet. However, its psychometric properties in Persian have never been examined and no studies have applied Rasch analysis for the psychometric testing. This study aimed to verify the construct validity of the Persian BSMAS using confirmatory factor analysis (CFA) and Rasch models among 2,676 Iranian adolescents. Methods In addition to construct validity, measurement invariance in CFA and differential item functioning (DIF) in Rasch analysis across gender were tested for in the Persian BSMAS. Results Both CFA [comparative fit index (CFI) = 0.993; Tucker-Lewis index (TLI) = 0.989; root mean square error of approximation (RMSEA) = 0.057; standardized root mean square residual (SRMR) = 0.039] and Rasch (infit MnSq = 0.88-1.28; outfit MnSq = 0.86-1.22) confirmed the unidimensionality of the BSMAS. Moreover, measurement invariance was supported in multigroup CFA including metric invariance (ΔCFI = -0.001; ΔSRMR = 0.003; ΔRMSEA = -0.005) and scalar invariance (ΔCFI = -0.002; ΔSRMR = 0.005; ΔRMSEA = 0.001) across gender. No item displayed DIF (DIF contrast = -0.48 to 0.24) in Rasch across gender. Conclusions Given the Persian BSMAS was unidimensional, it is concluded that the instrument can be used to assess how an adolescent is addicted to social media on the Internet. Moreover, users of the instrument may comfortably compare the sum scores of the BSMAS across gender.

Background: Dysphagia as a common condition affecting many aspects of the patient’s life. The Dysphagia Handicap Index (DHI) is a reliable self-reported questionnaire developed specifically to measure the impact of dysphagia on the patient’s quality of life. The aim of this study was to translate the questionnaire to Persian and to measure its validity and reliability in patients with neurogenic oropharyngeal dysphagia. Methods: A formal forward-backward translation of DHI was performed based on the guidelines for the cross-cultural adaptation of self-report measures. A total of 57 patients with neurogenic dysphagia who were referred to the neurology clinics of Tehran University of Medical Sciences, Iran, participated in this study. Internal consistency reliability of the DHI was examined using Cronbach’s alpha, and test-retest reliability of the scale was evaluated using intraclass correlation coefficient (ICC). Results: The internal consistency of the Persian DHI (P-DHI) was considered to be good; Cronbach’s alpha coefficient for the total P-DHI was 0.88. The test-retest reliability for the total and three subscales of the P-DHI ranged from 0.95 to 0.98 using ICC. Conclusion: The P-DHI demonstrated a good reliability, and it can be a valid instrument for evaluating the dysphagia effects on quality of life among Persian language population. PMID:27648173

Naphthalene is a ubiquitous pollutant of the marine environment, and naphthalene biodegradation has been receiving constant scientific consideration. For cleanup of aromatic contaminated sites, bioremediation methods are considered as economical and safe approaches for the marine environment. The aims of this research are isolation and characterization of naphthalene-degrading bacteria from some marine samples of the Persian Gulf. Fifty four naphthalene-degrading bacteria were isolated from marine samples (sediment and seawater) that are enriched in ONR7a medium with naphthalene as the only carbon source. Some screening tests such as growth at high concentration of naphthalene, bioemulsifier production and surface hydrophobicity were done to select the best and prevalent strains for naphthalene degradation. Determination of the nucleotide sequence of the gene encoding for 16S rRNA shows that these isolated strains belong to these genera: Shewanella, Salegentibacter, Halomonas, Marinobacter, Oceanicola, Idiomarina and Thalassospira. These strains can degrade half of the percentage of naphthalene in 10days of incubation. This research is the first report on isolation of these genera from the Persian Gulf as naphthalene-degrader.

The Asian citrus psyllid, Diaphorina citri Kuwayama, vectors Candidatus Liberibacter asiaticus (Las) and Candidatus Liberibacter americanus (Lam), the presumed causal agents of huanglongbing. D. citri generally rely on olfaction and vision for detection of host cues. Plant volatiles from Allium spp. (Alliaceae) are known to repel several arthropod species. We examined the effect of garlic chive (A. tuberosum Rottl.) and wild onion (A. canadense L.) volatiles on D. citri behaviour in a two-port divided T-olfactometer. Citrus leaf volatiles attracted significantly more D. citri adults than clean air. Volatiles from crushed garlic chive leaves, garlic chive essential oil, garlic chive plants, wild onion plants and crushed wild onion leaves all repelled D. citri adults when compared with clean air, with the first two being significantly more repellent than the others. However, when tested with citrus volatiles, only crushed garlic chive leaves and garlic chive essential oil were repellent, and crushed wild onions leaves were not. Analysis of the headspace components of crushed garlic chive leaves and garlic chive essential oil by gas chromatography-mass spectrometry revealed that monosulfides, disulfides and trisulfides were the primary sulfur volatiles present. In general, trisulfides (dimethyl trisulfide) inhibited the response of D. citri to citrus volatiles more than disulfides (dimethyl disulfide, allyl methyl disulfide, allyl disulfide). Monosulfides did not affect the behaviour of D. citri adults. A blend of dimethyl trisulfide and dimethyl disulfide in 1:1 ratio showed an additive effect on inhibition of D. citri response to citrus volatiles. The plant volatiles from Allium spp. did not affect the behaviour of the D. citri ecto-parasitoid Tamarixia radiata (Waterston). Thus, Allium spp. or the tri- and di-sulphides could be integrated into management programmes for D. citri without affecting natural enemies.

This is the first longitudinal cohort study of Persian Gulf War US soldiers to examine belief in exposure to chemical and biological weapons before and shortly after combat. A longitudinal sample of n = 1250 male Persian Gulf War US Army soldiers were surveyed 3 to 4 months before and 6 to 10 months after the 1991 War. Six to 10 months after combat, 4.6% of the cohort believed they had been exposed to chemical and biological weapons. Adjusting for demographics only, those who reported a greater number of combat exposures (odds ratio, OR: 18.8), or higher combat stress (OR: 12.27) were more likely to believe they were exposed. Adjusting for all variables soldiers who reported higher combat stress continued to be most likely (OR: 6.58) to believe they had been exposed to chemical and biological weapons. Individuals reporting higher combat stress are at substantially greater risk of reporting they have been exposed to chemical or biological weapons.

This research has identified areas located in the northern coastline of the Persian Gulf in the south of Iran, as strategic and ecological sites, based on tourism potential assessing criteria. To this end coastal limits were identified by satellite imagery in terms of shorelines and the maximum extent of water approach into the land and taking into consideration the characteristics of the nearby coastal villages. The studied region was then compared to similar international criteria and experiences. The original criteria were then divided into three main and four sub criteria. The Kangan region was found to have a potential for tourism industry according to the mentioned criteria. Naiband Gulf with a score of 20 was ranked first followed by Asalouyeh with a score of 18 and finally Taheri and Kangan Ports with scores of 16 and 15, respectively. With a high tourism industry potential in the studied region the necessity of ecotourism quality enhancement and environmental management planning for the northern shoreline of the Persian Gulf becomes of vital importance.

A rethinking on the benefits and drawbacks of common antioxidants and a proposal to look for the antioxidants in allium products as ideal agents: a review.

2012-01-01

This review article on the beneficial uses of Allium antioxidants tries to give some answers to the recent doubts raised by Singh et al. (Ind J Clin Biochem 25(3):225-243, 2010) against the claim of some researchers that Antioxidants (AOs) are miraculous molecules. Many people still believe that vitamins like A, C and E are the only true AOs that play important role in the corrections of metabolic derangements in life style diseases and hence all their faults are attributed to the failures of AOs as a class. This is quite unfair as there are many other natural AOs that do equal or even better AO action than the vitamins. Such is the case with the Allium S-alkyl sulfoxide aminoacids and their breakdown products viz, the various poly sulfides and their oxides e.g. allicin and ajoene type compounds which trap electrons mainly. It is true that antioxidant vitamins and β-carotene a precursor of Vitamin A bring about problems as prooxidant or as agents that block some metabolic pathways and gene expression. Again the argument that AOs cannot improve the level of antioxidant enzymes like SOD, catalase and glutathione Px is also not universal. Actually allium AOs can even spare the use of antioxidant vitamins in the body and enhance the action of antioxidant enzymes and supply of ATP and other nutrients to the tissues as the former are good vasodialators and promoters of membrane permeability. The use of AOs should be selective and moderate. Allium AOs satisfy the role of ideal AOs based on many of their invivo and invitro actions reported by the author and others. Their metabolits can regenerate them and recycle them for a sufficient time in the body. They have non antioxidant effects also such as antiplatelet, fibrinolytic, antiinflammatory, immunomodulatory, antiageing actions etc. Plant derived AOs may be more beneficial and better tolerated in their partially purified forms rather than in their absolutely purified forms as the accompanying principles have some

Esmail Jorjani was an influential Persian physician and anatomist of the 12th century who did most of his writing after his seventh decade of life. Jorjani's comprehensive textbook of medicine, Zakhirey-e Khwarazmshahi (The Treasure of the Khwarazm Shah) was written in approximately AD 1112 and is considered to be the oldest medical encyclopedia written in Persian. This was an essential textbook for those studying medicine during this time. We describe the life and times of Jorjani and provide a translation and interpretations of his detailed descriptions of the cranial nerves, which were written almost a millennium ago. Medieval Persian and Muslim scholars have contributed to our current knowledge of the cranial nerves. Some of these descriptions, such as the eloquent ones provided by Jorjani, were original and have gone mostly unknown to post-Vesalian European scholars.

Estimation of the major components of the hydrologic budget is important for determining the impacts on the water supply and quality of either planned or proposed land management projects, vegetative changes, groundwater withdrawals, and reservoir management practices and plans. As acquisition of field data is costly and time consuming, models have been created to test various land use practices and their concomitant effects on the hydrologic budget of watersheds. To simulate such management scenarios realistically, a model should be able to simulate the individual components of the hydrologic budget. The main objective of this study is to perform the SWAT2012 model for estimation of hydrological budget in six subbasin of Persian Gulf watershed; Golgol, Baghan, Marghab Shekastian, Tangebirim and Daragah, which are located in south and south west of Iran during 1991-2009. In order to evaluate the performance of the model, hydrological data, soil map, land use map and digital elevation model (DEM) are obtained and prepared for each catchment to run the model. SWAT-CUP with SUFI2 program was used for simulation, uncertainty and validation with 95 Percent Prediction Uncertainty. Coefficient of determination ( R 2) and Nash-Sutcliffe coefficient (NS) were used for evaluation of the model simulation results. Comparison of measured and predicted values demonstrated that each component of the model gave reasonable output and that the interaction among components was realistic. The study has produced a technique with reliable capability for annual and monthly water budget components in Persian Gulf watershed.

Corals in the Persian Gulf exist in a harsh environment with extreme temperature and salinity fluctuations. Understanding the health of these hardy corals may prove useful for predicting the survival of other marine organisms facing the impacts of global climate change. In this study, the health state of corals was surveyed along belt transects at 4 sites on the east side of Kish Island, Iran. Corals had a patchy distribution, low colony densities and species diversity, and were dominated by Acropora, Porites, and Dipsastrea. We found chronic sedimentation on corals, a high prevalence of old partial mortality, abundant bioeroders, and overgrowth of corals by sponges and bryozoans. These are all signs indicating suboptimal environmental conditions for coral reefs. Four types of tissue loss lesions consistent with disease were found: Porites multi-focal chronic tissue loss, Porites peeling tissue loss, Porites focal chronic tissue loss, and Dipsastrea focal sub-acute tissue loss. Overall disease prevalence was 3.6% and there were significant differences in prevalence among the 3 most abundant coral genera. Acropora was numerically dominant within transects yet showed no signs of disease, whereas Porites had a 14% disease prevalence, indicating differential susceptibility to disease among genera. Other coral lesions included pigmentation response in Porites associated with algae invasion or boring organisms, sponge overgrowth, and mucus sheathing in Dipsastrea. The Persian Gulf region is understudied, and this represents one of the first quantitative surveys of coral health and disease on these reefs.

2017-01-01

Diabetes mellitus is the most common endocrine disorder and a major cause of morbidity and mortality. Traditional medicines worldwide suggest a wide range of natural remedies for the prevention and treatment of chronic disorders, including diabetes mellitus. This mechanistic review aims to highlight the significance of medicinal plants traditionally used as dietary supplements in Persian medicine in adjunct with restricted conventional drugs for the prevention and treatment of diabetes mellitus. Mounting evidence suggests that these natural agents perform their protective and therapeutic effect on diabetes mellitus via several cellular mechanisms, including regeneration of pancreatic β cell, limitation of glycogen degradation and gluconeogenesis, anti-inflammatory, immunoregulatory, antiapoptosis, antioxidative stress, as well as modulation of intracellular signaling transduction pathways. In conclusion, traditional medicinal plants used in Persian medicine can be considered as dietary supplements with therapeutic potential for diabetes mellitus and maybe potential sources of new orally active agent(s).

The third-generation wave model, WAVEWATCH III, was employed to simulate bulk wave parameters in the Persian Gulf using three different wind sources: ERA-Interim, CCMP, and GFS-Analysis. Different formulations for whitecapping term and the energy transfer from wind to wave were used, namely the Tolman and Chalikov (J Phys Oceanogr 26:497-518, 1996), WAM cycle 4 (BJA and WAM4), and Ardhuin et al. (J Phys Oceanogr 40(9):1917-1941, 2010) (TEST405 and TEST451 parameterizations) source term packages. The obtained results from numerical simulations were compared to altimeter-derived significant wave heights and measured wave parameters at two stations in the northern part of the Persian Gulf through statistical indicators and the Taylor diagram. Comparison of the bulk wave parameters with measured values showed underestimation of wave height using all wind sources. However, the performance of the model was best when GFS-Analysis wind data were used. In general, when wind veering from southeast to northwest occurred, and wind speed was high during the rotation, the model underestimation of wave height was severe. Except for the Tolman and Chalikov (J Phys Oceanogr 26:497-518, 1996) source term package, which severely underestimated the bulk wave parameters during stormy condition, the performances of other formulations were practically similar. However, in terms of statistics, the Ardhuin et al. (J Phys Oceanogr 40(9):1917-1941, 2010) source terms with TEST405 parameterization were the most successful formulation in the Persian Gulf when compared to in situ and altimeter-derived observations.

Repetitive articulatory rate or Oral Diadochokinesis (oral-DDK) shows a guideline for appraisal and diagnosis of subjects with oral-motor disorder. Traditionally, meaningless words repetition has been utilized in this task and preschool children have challenges with them. Therefore, we aimed to determine some meaningful words in order to test oral-DDK in Persian speaking preschool children. Participants were 142 normally developing children, (age range 4-6 years), who were asked to produce /motæka, golabi/ as two meaningful Persian words and /pa-ta-ka/ as non-word in conventional oral-DDK task. We compared the time taken for 10-times fast repetitions of two meaningful Persian words and the tri-syllabic nonsense word /pa-ta-ka/. Praat software was used to calculate the average time that subjects took to produce the target items. In 4-5 year old children, [Formula: see text] of time taken for 10-times repetitions of /pa-ta-ka, motæka, golabi/ were [Formula: see text], and [Formula: see text] seconds respectively, and in 5-6 year old children were [Formula: see text], and [Formula: see text] seconds respectively. Findings showed that the main effect of type of words on oral diadochokinesis was significant ([Formula: see text]). Children repeated meaningful words /motæka, golabi/ faster than the non-word /pa-ta-ka/. Sex and age factors had no effect on time taken for repetition of oral-DDK test. It is suggested that Speech Therapists can use meaningful words to facilitate oral-DDK test for children.

Allium rotundum L. is a dietary plant with diverse nutritional and herbal applications. According to its widespread application in Iranians' diets, understanding the possible adverse effects and toxic activities could be of major importance. The aim of this study was to establish the acute and subchronic toxicity profile of the hydroalcoholic extract of Allium rotundum on male and female Wistar rats. The acute study indicated no adverse effect or toxic activity after administration of the extract, suggesting that the LD 50 value is up to 5,000 mg/kg body weight for the extract. The subchronic study at three doses (250, 500, and 750 mg/kg body weight/day) supported the results of acute study and revealed that no abnormal change or toxicity was induced by the extract in both male and female Wistar rats. All the biochemical and hematological parameters of the treated rats were in historical range after long-term administration of the extract. The histopathological examination also revealed no lesion or alteration in the tissue of vital organs (kidney, liver, heart, lung, and spleen). The NOAEL (no observed adverse effect level) value was high enough (greater than 750 mg/kg body weight/ day) to conclude the nontoxic nature of this extract. The safety of this extract was affirmed by the acute and subchronic toxic studies and suggested that this plant could be a proper and effective dietary plant due to its high nutritive value and inherent therapeutic properties.

The aim of this study was the translation, cross-cultural adaptation, and validation of the Sleep Apnea Quality of Life Index (SAQLI) in Persian-speaking patients with obstructive sleep apnea (OSA). Ninety-six patients with OSA completed a series of questionnaires including SAQLI, Epworth Sleepiness Scale (ESS),10-item Functional Outcomes of Sleep Questionnaire (FOSQ-10), and Medical Outcome Survey Short form 12 (SF-12) for assessment of reliability, validity, and responsiveness of Persian version of SAQLI. The Persian version of SAQLI had a very good internal consistency and also demonstrated good test-retest reliability. Concurrent validity was confirmed by significant correlations with ESS, FOSQ-10 and SF-12 subscale scores. Comparison of SAQLI scores in groups of patients categorized by ESS showed the high discriminative power of this instrument. However, there was no significant difference in the SAQLI scores of patients with mild, moderate, and severe sleep apnea. The results of sensitivity to change verified that the SAQLI was able to detect changes after continuous positive airway pressure (CPAP) treatment. The findings of this study indicate that the Persian version of SAQLI is a reliable, valid, and responsive measure for evaluation of quality of life in patients with OSA.

The purpose of the present study was to evaluate the psychometric properties (validity and reliability) of the Persian version of the Sustained Auditory Attention Capacity Test in children with attention deficit hyperactivity disorder. The Persian version of the Sustained Auditory Attention Capacity Test was constructed to assess sustained auditory attention using the method provided by Feniman and colleagues (2007). In this test, comments were provided to assess the child's attentional deficit by determining inattention and impulsiveness error, the total scores of the sustained auditory attention capacity test and attention span reduction index. In the present study for determining the validity and reliability of in both Rey Auditory Verbal Learning test and the Persian version of the Sustained Auditory Attention Capacity Test (SAACT), 46 normal children and 41 children with Attention Deficit Hyperactivity (ADHD), all right-handed and aged between 7 and 11 of both genders, were evaluated. In determining convergent validity, a negative significant correlation was found between the three parts of the Rey Auditory Verbal Learning test (first, fifth, and immediate recall) and all indicators of the SAACT except attention span reduction. By comparing the test scores between the normal and ADHD groups, discriminant validity analysis showed significant differences in all indicators of the test except for attention span reduction (p< 0.001). The Persian version of the Sustained Auditory Attention Capacity test has good validity and reliability, that matches other reliable tests, and it can be used for the identification of children with attention deficits and if they suspected to have Attention Deficit Hyperactivity Disorder.

It is important for clinician such as speech-language pathologists and audiologists to develop more efficient procedures to assess the development of auditory, speech and language skills in children using hearing aid and/or cochlear implant compared to their peers with normal hearing. So, the aim of study was the comparison of the performance of 5-to-7-year-old Persian-language children with and without hearing loss in visual-only, auditory-only, and audiovisual presentation of sentence repetition task. The research was administered as a cross-sectional study. The sample size was 92 Persian 5-7 year old children including: 60 with normal hearing and 32 with hearing loss. The children with hearing loss were recruited from Soroush rehabilitation center for Persian-language children with hearing loss in Shiraz, Iran, through consecutive sampling method. All the children had unilateral cochlear implant or bilateral hearing aid. The assessment tool was the Sentence Repetition Test. The study included three computer-based experiments including visual-only, auditory-only, and audiovisual. The scores were compared within and among the three groups through statistical tests in α = 0.05. The score of sentence repetition task between V-only, A-only, and AV presentation was significantly different in the three groups; in other words, the highest to lowest scores belonged respectively to audiovisual, auditory-only, and visual-only format in the children with normal hearing (P < 0.01), cochlear implant (P < 0.01), and hearing aid (P < 0.01). In addition, there was no significant correlationship between the visual-only and audiovisual sentence repetition scores in all the 5-to-7-year-old children (r = 0.179, n = 92, P = 0.088), but audiovisual sentence repetition scores were found to be strongly correlated with auditory-only scores in all the 5-to-7-year-old children (r = 0.943, n = 92, P = 0.000). According to the study's findings, audiovisual integration

A Glu-Phe (EF) was isolated from onion (Allium cepa L. cv. Sunpower). The chemical structure of EF was determined by nuclear magnetic resonance and electrospray ionization-mass (ESI-MS) spectroscopy. We showed that EF reduced lipid accumulation in mouse hepatocytes by inhibiting the expression of sterol regulatory element-binding protein-1c (SREBP-1c) and its lipogenic target genes. We also found that AMP-activated protein kinase (AMPK) was required for the inhibitory effect of EF on lipid accumulation in mouse hepatocytes. Furthermore, EF was qualified in nine onion cultivars by selective multiple reaction-monitoring detection of liquid chromatography-ESI-MS. These results suggest that EF could contribute to the beneficial effect of onion supplement in maintaining hepatic lipid homeostasis.

Genetic engineering has established itself to be an important tool for crop improvement. Despite the success, there is always a risk of food allergy induced by alien gene products. The present study assessed the biosafety of mutant Allium sativum leaf agglutinin (mASAL), a potent antifungal protein generated by site directed mutagenesis of Allium sativum leaf agglutinin (ASAL). mASAL was cloned in pET28a+ and expressed in E. coli, and the safety assessment was carried out according to the FAO/WHO guideline (2001). Bioinformatics analysis, pepsin digestion, and thermal stability assay showed the protein to be nonallergenic. Targeted sera screening revealed no significant IgE affinity of mASAL. Furthermore, mASAL sensitized Balb/c mice showed normal histopathology of lung and gut tissue. All results indicated the least possibility of mASAL being an allergen. Thus, mASAL appears to be a promising antifungal candidate protein suitable for agronomical biotechnology.

2018-03-01

Background and aims Research examining problematic mobile phone use has increased markedly over the past 5 years and has been related to "no mobile phone phobia" (so-called nomophobia). The 20-item Nomophobia Questionnaire (NMP-Q) is the only instrument that assesses nomophobia with an underlying theoretical structure and robust psychometric testing. This study aimed to confirm the construct validity of the Persian NMP-Q using Rasch and confirmatory factor analysis (CFA) models. Methods After ensuring the linguistic validity, Rasch models were used to examine the unidimensionality of each Persian NMP-Q factor among 3,216 Iranian adolescents and CFAs were used to confirm its four-factor structure. Differential item functioning (DIF) and multigroup CFA were used to examine whether males and females interpreted the NMP-Q similarly, including item content and NMP-Q structure. Results Each factor was unidimensional according to the Rach findings, and the four-factor structure was supported by CFA. Two items did not quite fit the Rasch models (Item 14: "I would be nervous because I could not know if someone had tried to get a hold of me;" Item 9: "If I could not check my smartphone for a while, I would feel a desire to check it"). No DIF items were found across gender and measurement invariance was supported in multigroup CFA across gender. Conclusions Due to the satisfactory psychometric properties, it is concluded that the Persian NMP-Q can be used to assess nomophobia among adolescents. Moreover, NMP-Q users may compare its scores between genders in the knowledge that there are no score differences contributed by different understandings of NMP-Q items.

Porosity and Health: Perspective of Traditional Persian Medicine

Tafazoli, Vahid; Nimrouzi, Majid; Daneshfard, Babak

2016-01-01

Background: The authors of this manuscript aimed to show the importance of porosity and condensation in health according to traditional Persian medicine (TPM) with consideration of new evidence in conventional medicine. Methods: Cardinal traditional medical and pharmacological texts were searched for the traditional terms of takhalkhol (porosity) and takassof (condensity) focused on preventive methods. The findings were classified and compared with new medical findings. Results: According to traditional Persian medicine, porosity and condensity are the two crucial items that contribute to human health. Somatotype is a taxonomy based on embryonic development, which may be considered in parallel with porosity and condensation. However, these terms are not completely the same. There are many causes for acquired porosity comprising hot weather, too much intercourse, rage, starvation, and heavy exercises. In general, porosity increases the risk of diseases as it makes the body organs vulnerable to external hot and cold weather. On the other hand, the porose organs are more susceptible to accumulation of morbid matters because the cellular wastes cannot be evacuated in the normal way. There are some common points between traditional and conventional medicine in the context of porosity and condensity. The relation between diet and somatotype is an example. Conclusion: Condensity and porosity are the two basic items cited in the TPM resources and contribute to health maintenance and disease prevention of body organs. Creating a balance between these two states in different body organs, strongly contributes to disease prevention, treatment and diminishing chronic diseases period. Choosing proper modality including diet, drug therapy, and manual therapy depends on the amount porosity and stiffness of the considered organ and the preferred porosity of the affected organ keeping in a normal healthy state.

The metabolic syndrome is a common problem world-wide and includes abdominal obesity, hypertension, dyslipidemia, and hyperglycemia disorders. It leads to insulin resistance and the development of diabetes mellitus or cardiovascular disease. Allium sativum (garlic) has been documented to exhibit anti-diabetic, hypotensive, and hypolipidemic properties. This suggests a potential role of A. sativum in the management of metabolic syndrome; however, more studies should be conducted to evaluate its effectiveness. In this review, we discussed the most relevant articles to find out the role of A. sativum in different components of metabolic syndrome and cardiovascular disease risk factors. Because human reports are rare, further studies are required to establish the clinical value of A. sativum in metabolic syndrome.

It is well known that Allium sativum has potential applications to clinical treatment of various cancers due to its remarkable ability in eliminating free radicals and increasing metabolism. An allyl-substituted cysteine derivative - S-allyl-L-cysteine (SAC) was separated and identified from Allium sativum. The extracted SAC was reacted with 1-pyrenemethanol to obtain pyrene-labelled SAC (Py-SAC) to give SAC fluorescence properties. Molecular detection of Py-SAC was conducted by steady-state fluorescence spectroscopy and time-resolved fluorescence method to quantitatively measure concentrations of Py-SAC solutions. The ability of removing 1,1-diphenyl-2-picrylhydrazyl (DPPH) and hydroxyl radical using Py-SAC was determined through oxygen radical absorbance capacity (ORAC). Results showed the activity of Py-SAC and Vitamin C (VC) with ORAC as index, the concentrations of Py-SAC and VC were 58.43 mg/L and 5.72 mg/L respectively to scavenge DPPH, and 8.16 mg/L and 1.67 mg/L to scavenge •OH respectively. Compared with VC, the clearance rates of Py-SAC to scavenge DPPH were much higher, Py-SAC could inhibit hydroxyl radical. The ability of removing radical showed a dose-dependent relationship within the scope of the drug concentration.

Two species of Atarbolana (Cirolanidae: Isopoda) from the intertidal zone of the Gulf of Oman and the Persian Gulf were studied and redescribed. The known distribution of this small genus is limited to the northern areas of the Indian Ocean, from the Pakistan coasts to the Persian Gulf. The analyses of DNA barcodes as well as detailed morphological studies clearly support the existence of three distinct Atarbolana species along the coastal zone of the Persian Gulf and northern Arabian Sea. Furthermore, A. dasycolus Yasmeen, 2004 is synonymized with A. setosa Javed and Yasmeen, 1989.

Environmental health concerns in the Persian Gulf are peculiar to the geography of the region. Prevention of heat and solar injury deserves primary consideration, but cold injury also may occur in the desert. Immunizations are recommended against a number of diseases, while malarial chemoprophylaxis is necessary in Iraq and Kuwait. In addition to malaria, other parasitic diseases deserve consideration. Diarrheal diseases, diseases from the desert dust, and products of infected desert animals are of concern. Additional natural hazards are venomous bites from scorpions and desert snakes. Finally, threats of enemy action necessitated protection from nuclear biological and chemical weapons and LASER eye/skin injury. Unexploded ordinance will constitute a continuing hazard into the future. Images Figure 2 PMID:1495114

2018-01-01

Due to the relatively low offspring survival rate, surviving adult leopards play a critical role in the species' viability. The unnatural mortality of leopards, caused by human activities can seriously compromise the species' long-term population survival. An analysis of spatial distribution and sex ratio of unnatural mortality of 147 recorded Persian leopard (Panthera pardus saxicolor) carcasses during a fifteen-year period (from 2000-2015) in Iran indicated that road mortality is the second most frequent cause of unnatural mortality of Persian leopards' after illegal hunting (or prey poisoning, such as poisoned meat) by villagers, shepherds and military forces. The greatest percent of unnatural mortality events were recorded in the Golestan provinc in the north of Iran and eastern most parts of the Hyrcanian forests. Using distribution models of species, based on road accident locations as species data, we mapped the species' distribution and critical areas of unnatural mortality of Persian leopard that can be used in prioritizing leopard-human conflicts management. Our results showed that mortality records were significantly higher in non-protected compared to protected areas. Males constituted 65 percent of the records used in the study as males dispersed more widely compared to the females. This imbalance can have severe demographic effects. A large proportion of leopards' activity, occurrence area, and habitat lies in non-protected areas, which is mirrored by the greater number of unnatural mortality outside protected areas. Most of the incidents were due to human factors, thus management interventions such as traffic speed limitations, signs, cameras, and faunal bridges as well as increasing public participation and awareness (especially among rural communities) will positively affect the species' conservation programs. This research aimed to produce unnatural mortality of leopards' risk map throughout Iran and discuss the different aspects of this

Character and dynamics of the Red Sea and Persian Gulf outflows

Historical hydrographic data and a numerical plume model are used to investigate the initial transformation, dynamics, and spreading pathways of Red Sea and Persian Gulf outflow waters where they enter the Indian Ocean. The annual mean transport of these outflows is relatively small (<0.4 Sv), but they have a major impact on the hydrographic properties of the Indian Ocean at the thermocline level because of their high salinity. They are different from other outflows in that they flow over very shallow sills (depth < 200 m) into a highly stratified upper ocean environment and they are located at relatively low latitudes (12°N and 26°N). Furthermore, the Red Sea outflow exhibits strong seasonal variability in transport. The four main results of this study are as follows. First, on the basis of observed temperature-salinity (T-S) characteristics of the outflow source and product waters we estimate that the Red Sea and Persian Gulf outflows are diluted by factors of ˜2.5 and 4, respectively, as they descend from sill depth to their depth of neutral buoyancy. The high-dilution factor for the Persian Gulf outflow results from the combined effects of large initial density difference between the outflow source water and oceanic water and low outflow transport. Second, the combination of low latitude and low outflow transport (and associated low outflow thickness) results in Ekman numbers for both outflows that are O(1). This indicates that they should be thought of as frictional density currents modified by rotation rather than geostrophic density currents modified by friction. Third, different mixing histories along the two channels that direct Red Sea outflow water into the open ocean result in product waters with significantly different densities, which probably contributes to the multilayered structure of the Red Sea product waters. In both outflows, seasonal variations in source water and oceanic properties have some effect on the T-S of the product waters, but

Bulb onion (Allium cepa) is the second most widely cultivated and consumed vegetable crop in the world. During winter, cold injury can limit the production of bulb onion. Genomic resources available for bulb onion are still very limited. To date, no studies on heritably durable cold and freezing tolerance have been carried out in bulb onion genotypes. We applied high-throughput sequencing technology to cold (2°C), freezing (-5 and -15°C), and control (25°C)-treated samples of cold tolerant (CT) and cold susceptible (CS) genotypes of A. cepa lines. A total of 452 million paired-end reads were de novo assembled into 54,047 genes with an average length of 1,331 bp. Based on similarity searches, these genes were aligned with entries in the public non-redundant (nr) database, as well as KEGG and COG database. Differentially expressed genes (DEGs) were identified using log10 values with the FPKM method. Among 5,167DEGs, 491 genes were differentially expressed at freezing temperature compared to the control temperature in both CT and CS libraries. The DEG results were validated with qRT-PCR. We performed GO and KEGG pathway enrichment analyses of all DEGs and iPath interactive analysis found 31 pathways including those related to metabolism of carbohydrate, nucleotide, energy, cofactors and vitamins, other amino acids and xenobiotics biodegradation. Furthermore, a large number of molecular markers were identified from the assembled genes, including simple sequence repeats (SSRs) 4,437 and SNP substitutions of transition and transversion types of CT and CS. Our study is the first to provide a transcriptome sequence resource for Allium spp. with regard to cold and freezing stress. We identified a large set of genes and determined their DEG profiles under cold and freezing conditions using two different genotypes. These data represent a valuable resource for genetic and genomic studies of Allium spp. PMID:27627679

2016-10-15

Geriatrics are a group of patients over 65 years and with multiple comorbidities and different functional impairments. Apart from decline in body mass, presence of exhaustion and general fatigue, an aged person may also suffer from various disorders. Approximately, around 30% of geriatric subjects have significant cardiovascular ailments. Apart from the intensive management of cardiovascular aspects in elderly, monitoring of the complementary cardiac medicine in those people should be received more attention. There are many management lines for a cardio-geriatric condition in Traditional Persian Medicine (TPM). Accordingly, this paper aimed to deal with those medicaments as well as evidence-based clinical aspects and phytochemistry. By searching through main pharmaceutical manuscripts of Persian medicine during 10th-18th centuries (A.D.), concurrently, natural medicines for geriatrics and remedies for cardiovascular ailments were derived. On the other side, related phytochemical and pharmacological aspects of those remedies were highlighted. In all, 38 cardiovascular and 34 geriatric medicaments were found in those manuscripts. Antihyperlipidemic and cholesterol lowering activities of those medicines were the most reported activities in current medicine. However, other pharmacological reports were related to hypotensive, coagulant, cardio-protective and cardiotonic activities. In regard of the chemical composition, medicaments were mainly of polyphenols and flavonoids and also most of the employed extracts and fractions were yielded from polar or semi-polar solvents. With reference to these findings, flavonoid-rich medicaments from Persian medicine may be selected as considerable herbs for geriatrics with cardiovascular ailments. Copyright © 2016 Elsevier GmbH.

Oral cancer is a global health problem; however, many dentists lack the necessary skills, knowledge and capacity to diagnose oral cancers early. This study aimed to examine the validity and reliability of a Persian short-form version of a standardised questionnaire to assess dentists' knowledge, practice and attitudes towards oral cancer. This cross-sectional analytical study was carried out in May 2015 in Tehran, Iran. An original 39-item English-language questionnaire developed by Yellowitz et al . was translated into Persian using forward and backward translation methods. A total of 15 dental professionals were asked to assess the questionnaire for content validity. Based on their feedback, a 20-item short-form version was prepared, including six demographic, six knowledge, four attitude and four practice items. The translated short-form questionnaire was subsequently distributed to 973 general dental practitioners attending a dental conference in Tehran. Internal consistency and reliability were assessed with Cronbach's alpha coefficient and item-total correlation calculations. A total of 13 professionals and 313 general dentists participated in the study (response rates: 86.7% and 32.2%, respectively). After the elimination of six items (two knowledge, two attitude and two practice items), the validity and reliability of the questionnaire was confirmed. The final Persian 14-item version of the questionnaire had acceptable validity and internal consistency. These results indicate that researchers can use this translated short-form version to evaluate oral cancer knowledge, attitudes and practices among Persian-speaking dentists; this will allow for a comparison of data between different populations.

To date, little is known about existing relationships between mussels and bacteria in hydrocarbon-contaminated marine environments. The aim of this study is to find crude oil degrading bacteria in some mussels at the Persian Gulf. Twenty eight crude oil degrading bacteria were isolated from three mussels species collected from oil contaminated area at Persian Gulf. According to high growth and degradation of crude oil four strains were selected between 28 isolated strains for more study. Determination the nucleotide sequence of the gene encoding for 16S rRNA show that these isolated strains belong to: Shewanella algae isolate BHA1, Micrococcus luteus isolate BHA7, Pseudoalteromonas sp. isolate BHA8 and Shewanella haliotis isolate BHA35. The residual crude oil in culture medium was analysis by Gas Chromatography (GC). The results confirmed that these strains can degrade: 47.24%, 66.08%, 27.13% and 69.17% of crude oil respectively. These strains had high emulsification activity and biosurfactant production. Also, the effects of some factors on crude oil degradation by isolated strains were studied. The results show that the optimum concentration of crude oil was 2.5% and the best degradation take place at 12% of salinity. This research is the first reports on characterization of crude oil degrading bacteria from mussels at Persian Gulf and by using of these bacteria in the field the effect of oil pollution can be reduce on this marine environment.

According to historical evidence, the abuse of opium has been reported all over the globe-specifically throughout Eastern nations-since the sixteenth century. Before that, opium had mostly been applied as medication. Reference has been made in traditional Persian medical literature to the method of cultivation, properties, side effects and toxicity. In sixteenth century Iran, during the reign of the Safavids, opium abuse began. It was from then that prominent Persian scholars started to think of solutions to this societal problem. One of the most famous scholars was Imad al-Din Mahmud ibn Mas'ud Shirazi, who composed a book concerning addiction-Afyunieh, a comprehensive book on the topic of opium and all issues of opium. Furthermore, he recommended methods for reducing opium dose as well as substitution with other medications that had a narrower range of side effects, in order to eradicate dependency upon opium and opium-derived materials. This is most likely the first book that comprehensively addressed opium and discussed drug rehabilitation methodology, in traditional Persian medical literature. In this historical review, the authors have introduced the book Afyunieh, which presents methods for treating addiction to and giving up opium; the text comprises a synthesis of the author's opinions, professional experience and references to the work of other famous physicians.

Nimrouzi, Majid; Zarshenas, Mohammad Mehdi

2018-01-01

Objective: Anorexia and impaired appetite (Dysorexia) are common symptoms with varying causes, and often need no serious medical intervention. Anorexia nervosa (AN) is a chronic psychiatric disease with a high mortality rate. In Traditional Persian Medicine (TPM), anorexia is a condition in which anorexic patients lose appetite due to dystemperament. This review aims to discuss the common points of traditional and conventional approaches rather than introducing Persian medical recommendations suitable for nowadays use. Materials and Methods: For this purpose, Avicenna's Canon of Medicine, main TPM resources and important databases were reviewed using the related keywords. Results: Despite complex hormonal explanation, etiology of AN in conventional approach is not completely understood. In TPM approach, the etiology and recommended interventions are thoroughly defined based on humoral pathophysiology. In TPM approach, disease states are regarded as the result of imbalances in organs’ temperament and humors. In anorexia with simple dystemperament, the physician should attempt to balance the temperament using foods and medicaments which have opposite quality of temperament. Lifestyle, spiritual diseases (neuro – psychological) and gastrointestinal worms are the other causes for reducing appetite. Also, medicines and foods with warm temperaments (such as Pea soup and Mustard) are useful for these patients (cold temperament). Conclusion: Although the pathophysiology of AN in TPM is different in comparison with conventional views, TPM criteria for treatment this disorder is similar to those of current medicine. Recommending to have spiritual support and a healthy lifestyle are common in both views. Simple safe interventions recommended by TPM may be considered as alternative medical modalities after being confirmed by well-designed clinical trials. PMID:29387569

A cross-sectional postal survey was conducted to evaluate the health of a random sample of United Kingdom Armed Forces personnel who were deployed to the 1990-1991 Persian Gulf conflict compared with nondeployed controls and controls deployed to Bosnia. The health of service women was examined and compared with that of United Kingdom service men. The main outcome measures were physical symptoms and ailments, functional capacity on the 36-item Short-Form Health Survey, the 12-item General Health Questionnaire, the Centers for Disease Control and Prevention multisymptom criteria for Gulf War illness, and post-traumatic stress reactions. There were 645 (65.3%) valid responses. The women from the Gulf cohort reported each symptom and the majority of health outcomes more frequently than either control group. No gender differences were found for 32 of the 50 symptoms assessed. Of the remaining 18 symptoms, women reported significantly more than men for only 6 of them, and there were no gender differences in 5 of the 6 principal health outcome measures. Women deployed to the Persian Gulf had similar rates of ill health as their male counterparts. Nothing was found to suggest that, other than for gender-specific health effects, any special considerations need to be made on health grounds for service women in any future deployments.

Antioxidant potential has protective effects in diabetic neuropathy (DN); hence, the present study was designed with an objective to quantify quercetin from shade-dried leaves of Allium cepa Lam. and to study its effects on streptozotocin (STZ)-induced chronic DN. The shade-dried leaves of A. cepa Lam. were extracted with methanol and then fractionated using ethyl acetate (ACEA). The quantification of quercetin in ACEA was evaluated by high-performance thin layer chromatography (HPTLC). The STZ (40 mg/kg) was administered to Sprague-Dawley rats (180-250 g) maintained at normal housing conditions. The STZ was administered once a day for 3 consecutive days. The elevation in blood glucose was monitored for 3 weeks periodically using flavin adenine dinucleotide-glucose dehydrogenase method by Contour TS glucometer. Rats showing blood glucose above 250 mg/dl were selected for the study. Animals were divided into eight groups. ACEA (25, 50, and 100 mg/kg), quercetin (40 mg/kg), metformin (120 mg/kg), and gabapentin (100 mg/kg) were given orally once a day for 2 weeks. The blood glucose level was again measured at the end of treatment to assess DN. Thermal hyperalgesia, cold allodynia, motor incoordination, and neurotoxicity were studied initially and at the end of 2-week treatment. Biochemical parameters were also evaluated after 2-week drug treatment. The quercetin present in ACEA was 4.82% by HPTLC. All the ACEA treatment reduces blood glucose level at the end of the 2-week study and shows a significant neuroprotective effect in STZ-induced DN in the above experimental models. The quercetin present in ACEA proved protective effect in STZ-induced DN. High-performance thin layer chromatography reveals the presence of 4.82% quercetin in Allium cepa ethyl acetate. (ACEA). Its investigation against various diabetic neuropathy biomarkers has proved that ACEA has significant blood glucose reducing action shown neuroprotective action in thermal hyperalgesia, motor

Veterans of the Persian Gulf War of 1991 have reported symptoms attributed to their military service. To review all studies comparing the prevalence of psychiatric disorders in Gulf War veterans and in a comparison group of service personnel not deployed to the Gulf War. Studies of military personnel deployed to the Gulf published between 1990 and 2001 were identified from electronic databases. Reference lists and websites were searched and key researchers were contacted for information. A total of 2296 abstracts and 409 complete articles were reviewed and data were extracted independently by two members of the research team. The prevalence of psychiatric disorder in 20 studies of Gulf War veterans was compared with the prevalence in the comparison group. Prevalence of post-traumatic stress disorder (PTSD) and common mental disorder were higher in the Gulf War veterans. Heterogeneity between studies was significant, but all reported this increased prevalence. Veterans of the Persian Gulf War reported an increased prevalence of PTSD and common mental disorder compared with other active service personnel not deployed to the Gulf. These findings are attributable to the increase in psychologically traumatic events in wartime.

No tools are available to assess or measure the experience of chemotherapy-induced nausea and vomiting (CINV) for Persian/Farsi speakers. The purpose of this study is to translate the Rhodes Index of Nausea, Vomiting and Retching (INVR) scale for use with Persian-speaking cancer patients. A sample of 94 cancer patients were recruited from a cancer research centre in Mashhad-Iran. A standard two phase process of scale translation and validation was conducted. In phase I, standard 'forward-backward' translation procedure was used to translate the original version of the INVR questionnaire into Persian. The translated questionnaire was reviewed and revised and a Persian version of the scale was produced. In the second phase, a multiphase instrumentation study describing the internal consistency and test-retest reliability of the translated version was conducted. The inter-item correlation measured by Cronbach's alpha was 0.88. Test/re-test reliability was measured by the weighted kappa and was between 0.63 and 0.79, indicating 'substantial agreement' and stability between the initial and subsequent administrations for each item. These results demonstrate that the Persian version of the INVR is acceptable for use among Iranian cancer patients. Researchers could use this study as a model for future translation and application of psychometric instrumentation. © 2013 John Wiley & Sons Ltd.

Excessive usage of fossil fuels and high emission of greenhouse gases have increased the earth's temperature, and consequently have changed the patterns of natural phenomena such as wind speed, wave height, etc. Renewable energy resources are ideal alternatives to reduce the negative effects of increasing greenhouse gases emission and climate change. However, these energy sources are also sensitive to changing climate. In this study, the effect of climate change on wave energy in the Persian Gulf is investigated. For this purpose, future wind data obtained from CGCM3.1 model were downscaled using a hybrid approach and modification factors were computed based on local wind data (ECMWF) and applied to control and future CGCM3.1 wind data. Downscaled wind data was used to generate the wave characteristics in the future based on A2, B1, and A1B scenarios, while ECMWF wind field was used to generate the wave characteristics in the control period. The results of these two 30-yearly wave modelings using SWAN model showed that the average wave power changes slightly in the future. Assessment of wave power spatial distribution showed that the reduction of the average wave power is more in the middle parts of the Persian Gulf. Investigation of wave power distribution in two coastal stations (Boushehr and Assalouyeh ports) indicated that the annual wave energy will decrease in both stations while the wave power distribution for different intervals of significant wave height and peak period will also change in Assalouyeh according to all scenarios.

The clinical COPD questionnaire (CCQ) has been developed to measure the health status of COPD patients. The aim of this study was to translate CCQ into the Persian language and assess the validity and reliability of the translated version. We used a forward-backward procedure to translate the questionnaire. In a cross-sectional study 100 COPD patients and 50 healthy subjects over 40 years old were selected to assess the reliability and construct validity of the instrument. The face and content validity were used for the questionnaire validity. Validity was examined in a population of patients with COPD, using the Persian validated version of the St George's Respiratory Questionnaire (PSGRQ). In order to assess the questionnaire's reliability, the Intraclass correlation coefficient (ICC) and Cronbach's alpha were calculated. Test-retest reliability was tested by re-administering the Persian version of the CCQ (PCCQ) after 1 week. Test-retest carry out of data demonstrates that the PCCQ has excellent reliability (ICC for all 3 domains were higher than 0.9). Internal consistency was found by Cronbach's alpha to be 0.96, 0.94, 0.97, and 0.98 for the symptom, mental state, functional state and total scores respectively. In addition, the correlation between the components of PCCQ and PSGRQ showed satisfactory construct validity. Analyzing the data from healthy subjects and patients divulged that the PCCQ has acceptable discriminant validity. In general, the PCCQ had satisfactory reliability and validity for assessing health-related quality of life status of Iranian COPD patients.

In various traditional medicines, onion has been classified as an immune-boosting food. Recent studies have claimed this property due to the presence of bioactive organosulfur compounds, prebiotic fructo-oligosaccharides and an immunomodulatory protein, lectin (Allium cepa agglutinin; ACA) (Prasanna and Venkatesh, 2015. Characterization of onion lectin (Allium cepa agglutinin) as an immunomodulatory protein inducing Th1-type immune response in vitro. Int. Immunopharmacol. vol. 26, pp. 304-313). The aim of this study was to evaluate the immunoprotective properties of ACA in normal and cyclophosphamide (CP; 100μg/kg)-induced immunosuppressed Wistar rats. Wistar rats were administrated different doses of ACA (1, 10, and 100μg) to respective groups in normal as well as immunosuppressed animals. The effect of ACA on the status of immune organs was assessed by examining the splenic and thymic indices, and histopathological changes. The biomarkers for humoral immunity (serum IgG and IgA levels) and serum pro-inflammatory markers (COX-2, TNF-α and IL-10) were measured by ELISA. ACA showed immunoprotective properties by significantly promoting the restoration of lymphoid cell count by ~6 fold vs. model control (immunosuppressed animals) and promotes the immune response significantly (~1.5-fold) in CP-induced immunosuppressed animals compared to model control; production of pro-inflammatory molecules (COX-2 and nitric oxide) and expression levels of immune regulatory molecule (TNF-α) were elevated in a dose-dependent manner. The observed in vivo results suggest that ACA has the potential to be used as a nutritional therapeutic to boost the immune status of immunosuppressed subjects brought about by CP administration.

Improving the nutritional value of commonly cultivated crops is one of the most pending problems for modern agriculture. In natural environments plants associate with a multitude of fungal microorganisms that improve plant fitness. The best described group are arbuscular mycorrhizal fungi (AMF). These fungi have been previously shown to improve the quality and yield of several common crops. In this study we tested the potential utilization of Rhizophagus irregularis in accelerating growth and increasing the content of important dietary phytochemicals in onion (Allium cepa). Our results clearly indicate that biomass production, the abundance of vitamin B1 and its analogues and organic acid concentration can be improved by inoculating the plant with AM fungi. We have shown that improved growth is accompanied with up-regulated electron transport in PSII and antioxidant enzyme activity. Copyright © 2016 Elsevier Masson SAS. All rights reserved.

Essential oils from onion (Allium cepa L.), garlic (Allium sativum L.), and their main components, such as propyl thiosulfinate oxide (PTSO) are being intended for active packaging with the purpose of maintaining and extending food product quality and shelf life. The present work aims to assess for the first time the potential mutagenicity/genotoxicity of PTSO (0-50 µM) using the following battery of genotoxicity tests: (1) the bacterial reverse-mutation assay in Salmonella typhimurium (Ames test, OECD 471); (2) the micronucleus test (OECD 487) (MN) and (3) the mouse lymphoma thymidine-kinase assay (OECD 476) (MLA) on L5178YTk(+/-), cells; and (4) the comet assay (with and without Endo III and FPG enzymes) on Caco-2 cells. The results revealed that PTSO was not mutagenic in the Ames test, however it was mutagenic in the MLA assay after 24 h of treatment (2.5-20 µM). The parent compound did not induce MN on mammalian cells; however, its metabolites (in the presence S9) produced positive results (from 15 µM). Data from the comet assay indicated that PTSO did not induce DNA breaks or oxidative DNA damage. Further in vivo genotoxicity tests are needed to confirm its safety before it is used as active additive in food packaging. Copyright © 2015 Elsevier Ltd. All rights reserved.

A Persian-version of the stuttering severity instrument-version four (SSI-4): How the new additions to SSI-4 complement its stuttering severity score?

Tahmasebi, Neda; Shafie, Bijan; Karimi, Hamid; Mazaheri, Masood

The fourth version of the Stuttering Severity Instrument (SSI-4) has been available since 2009. It has some modifications and new features which make it more appropriate at least for clinical practice, although further documentation is needed. The objective of the current research was to translate SSI-4 into Persian language and to discuss its relative and absolute reliability as well as its criterion validity for Persian adults who stutter (PWS). We also aimed to study how the new subjective self-reports of the SSI-4 complement the stuttering severity score obtained from the SSI-3 or the SSI-4. The cross-cultural guideline recommended by the International Quality of Life Assessment project was used to translate the SSI-4 into Persian language. Thirty five PWS from ages 17 to 42 were recruited and 10 speech and language pathologists assessed their stuttering severity using either the SSI-4 or stuttering severity ratings (SR) to test validity and reliability of the Persian translated version. A very high inter-judge relative reliability along with a poor absolute inter-judge reliability was found for the SSI-4 scores. The results were more promising for the intra-judge absolute reliability. Test-retest reliability of the complementary questions to the SSI-4 was also found acceptable. However, no strong relationship was found between the SSI-4 scores and its complementary questions. The Persian version of the SSI-4 can be used reliably by trained SLPs for research and clinical purposes, but not to document small changes in stuttering severity. We argue that the response of participants to the complementary self-report questions should also be considered in calculating their stuttering severity score. Copyright © 2018 Elsevier Inc.

The aim of the study was to determine enzymatic activity in sterile Allium sativum anthers in the final stages of male gametophyte development (the stages of tetrads and free microspores). The analysed enzymes were shown to occur in the form of numerous isoforms. In the tetrad stage, esterase activity was predominant, which was manifested by the greater number of isoforms of the enzyme. In turn, in the microspore stage, higher numbers of isoforms of acid phosphatases and proteases were detected. The development of sterile pollen grains in garlic is associated with a high level of protease and acid phosphatase activity and lower level of esterase activities in the anther locule. Probably this is the first description of the enzymes activity (ACPH, EST, PRO) in the consecutives stages of cell wall formation which is considered to be one of the causes of male sterility in flowering plant.

Spirituality plays an important role in coping with chronic diseases for patients and they often report unmet spiritual and existential needs, which should be considered for a holistic view of their health. Studying spiritual needs in this generation requires culturally appropriate and valid instruments. The aim of this study was to determine the psychometric properties, such as validity, reliability, and factor structure of the Persian version of Spiritual Needs Questionnaire (SpNQ). The aim of this study was to determine the psychometric properties, such as validity, reliability, and factor structure of the Persian version of Spiritual Needs Questionnaire (SpNQ). The "forward-backward" procedure was applied to translate the SpNQ from English into Persian. The SpNQ-Persian Version (SpNQ-PV) was checked in terms of validity and reliability with a convenience sample of 100 elders with chronic diseases who were recruited from the inpatient wards at two university hospitals in Qom, Iran. The validity was assessed using content, face, and construct validity. The Cronbach alpha and test-retest were used to assess the reliability of the questionnaire. The results of the exploratory factor analysis indicated a five-factor solution for the questionnaire, which included religious needs, existential needs, forgiveness/generativity needs, need for inner peace, and emotional needs. These accounted for 60.1% of the total observed variance. One item was removed (factor loading <0.4). Convergent validity was supported mostly by the pattern of association between SpNQ-PV and the Spiritual Well-being Scale. Cronbach alpha of the subscales ranged from 0.56 to 0.78 and the test-retest reliability ranged from 0.72 to 0.91, which indicated an acceptable range of reliability. The SpNQ-PV showed a minor difference in structuring and indicated good psychometric properties, which can be used to assess the spiritual needs of Iranian elders suffering from chronic diseases.

Field experiment were conducted at CSK HPKV Research Farm, Palampur during Rabi seasons of 2000-01 and 2001-02, to study the response of onion (Allium cepa var Patna red) at four sulphur levels (0, 15, 30 and 60 kg ha(-1)) applied through Gypsum and S95. The analysis was done to allocate the limited availability of sulphur for maximizing net profit over fertilizer cost. The results show that the dose of sulphur under its full availability is 43.02 kg ha(-1). But under its scarce availability the maximum benefit would occur when it is applied up to 32.11 kg ha(-1) followed by even distribution of fertilizer i.e. 20 kg ha(-1). The returns following sulphur application at these rates, would be Rs 69340, 73092 and 68700 ha(-1) respectively.

Case summary This report describes a rare case of crossed fused renal ectopia (CFRE) in a cat. A mature intact male Persian cat presented with bloody nasal discharge and ascites. Diagnostic studies revealed an ectopic left kidney fused with an orthotopic right kidney and a concurrent feline infectious peritonitis (FIP) infection. The FIP was responsible for clinical signs in this cat, while clinical signs associated with CFRE were not obvious. Despite receiving intensive treatment, the cat died. A post-mortem examination was not performed because the owners declined approval. Relevance and novel information To the best of our knowledge, this is the first report of L-shaped CFRE in a cat. In addition, this report describes the CT features of L-shaped CFRE in a cat. PMID:28491454

Various symptoms frequently affect cancer patients' quality of life. Appropriate assessment of these symptoms provides valuable data for cancer management. This study aimed to validate the Persian version of the M. D. Anderson Symptom Inventory (MDASI-P). This cross-sectional study was conducted at four cancer treatment centers in two cities in Iran. Breast cancer and colorectal cancer patients aged 18 years and older were consecutively included in the study. The standard forward-backward translation method was applied. Patients completed the MDASI-P along with the previously validated Persian version of the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Core 30 (EORTC QLQ-C30). Construct validity (factor analysis), criterion validity (against the EORTC QLQ-C30), and reliability (Cronbach's alpha) were analyzed. A total of 146 breast cancer and 94 colorectal cancer patients were studied. Factor analysis for the symptom severity items resulted in a three-factor solution, further reduced to a two-factor solution: general symptoms and gastrointestinal symptoms. Correlation of the MDASI-P symptom severity items with corresponding EORTC QLQ-C30 symptom items (r = 0.48-0.75) and MDASI-P interference items with corresponding EORTC QLQ-C30 functioning domains (r = -0.46 to -0.23) supported the criterion validity. Cronbach's alpha was 0.90, 0.88, and 0.77 for the total questionnaire, symptom severity items, and the interference subscale, respectively. The MDASI-P is a feasible, valid, and reliable instrument for evaluation of symptoms in Persian-speaking cancer patients and can be used to improve symptom management in these patients.

The aim of this study is to translate, adapt, and validate a Persian version of the Fibromyalgia (FM) Impact Questionnaire (FIQ-P). The FIQ-P was adapted following the translation and back-translation approach; then, it was administered to thirty females with FM. Participants also completed two other validated questionnaires, the Medical Outcome Survey Short Form-36 (SF-36) and the Beck Depression Inventory (BDI). Internal consistency within the FIQ-P items and its test-retest reliability were assessed with Cronbach's alpha and Spearman's correlation coefficient, respectively. Construct validity was analyzed by Spearman's r when correlating the FIQ-P to other questionnaires. The translated version was concordant. Adaptation affected two sub-items of physical function. Participants' mean age ± standard deviation was 40.4 ± 9.0 years. Internal consistency proved good with α = 0.80. Test-retest coefficient ranged from 0.50 for the item "work days missed" to 0.79 for all FIQ-P items. Fair and statistically significant (P < 0.01) correlations were found between the FIQ-P items and two other questionnaires, SF-36 (r = -0.57) and BDI (r = 0.53). We concluded that the FIQ-P is a valid and reliable instrument for measuring health status of Persian-speaking FM patients.

Superoxide dismutases (SODs; EC 1.15.1.1) are key enzymes in the cells protection against oxidant agents. Thus, SODs play a major role in the protection of aerobic organisms against oxygen-mediated damages. Three SOD isoforms were previously identified by zymogram staining from Allium sativum bulbs. The purified Cu, Zn-SOD2 shows an antagonist effect to an anticancer drug and alleviate cytotoxicity inside tumor cells lines B16F0 (mouse melanoma cells) and PAE (porcine aortic endothelial cells). To extend the characterization of Allium SODs and their corresponding genes, a proteomic approach was applied involving two-dimensional gel electrophoresis and LC-MS/MS analyses. From peptide sequence data obtained by mass spectrometry and sequences homologies, primers were defined and a cDNA fragment of 456 bp was amplified by RT-PCR. The cDNA nucleotide sequence analysis revealed an open reading frame coding for 152 residues. The deduced amino acid sequence showed high identity (82-87%) with sequences of Cu, Zn-SODs from other plant species. Molecular analysis was achieved by a protein 3D structural model.

Rodents frequently serve as bioindicator to monitor the quality of the environment. Concentrations of 11 elements (Cd, Co, Ti, Fe, Mn, Cu, Sb, As, Sr, Ni, and Cr) were investigated and compared in liver, hair, femur, and lung of the Persian jird (Meriones persicus) from Darreh Zereshk copper mine, Iran. Metals were determined in different tissues of 39 individuals of Persian jird, collected by snap trap in 2014 from five areas of Darreh Zereshk copper mine. Samples were prepared by wet digestion method, and the contents of elements were analyzed with ICP-OES (VARIAN, 725-ES) instrument. Cadmium, Sb, and Co were below the limit of detection, and Mn and As were found only in hair and liver tissues. We detected the highest concentration of Cu, As, Ti, Fe, Mn, Cr, and Ni in hair in comparison with other tissues. Significant higher levels of Ti in femur and hair; Fe in liver and hair; Mn in liver; As in hair; Sr in lung; Cr in lung, hair, femur, and liver; Cu in femur; and Ni in liver and lung tissues were observed in females. Nearly all element concentrations in the tissues of Persian jird from flotation site, Darreh Zereshk and Hasan Abad villages and leaching site (mining areas) were higher than those from tailing dump site (reference site). We found the highest concentrations of As in liver and hair; Ni and Cr in liver, hair, and lung; and Sr in lung and hair tissues of Persian jird in leaching site. We tried to specify the status of elements before fully exploitation of Darreh Zereshk copper mine by using bioindicator species. Based on our achievements, initial activities did not strongly pollute the surrounded environment of the mine. The high abundance of Persian jird as well as their several proper features makes them a suitable species for biomonitoring programs especially for further studies will be performed after full exploitation of Darreh Zereshk copper mine.

Kubec, Roman; Dadáková, Eva

2009-10-09

A novel HPLC method for determination of a wide variety of S-substituted cysteine derivatives in Allium species has been developed and validated. This method allows simultaneous separation and quantification of S-alk(en)ylcysteine S-oxides, gamma-glutamyl-S-alk(en)ylcysteines and gamma-glutamyl-S-alk(en)ylcysteine S-oxides in a single run. The procedure is based on extraction of these amino acids and dipeptides by methanol, their derivatization by dansyl chloride and subsequent separation by reversed phase HPLC. The main advantages of the new method are simplicity, excellent stability of derivatives, high sensitivity, specificity and the ability to simultaneously analyze the whole range of S-substituted cysteine derivatives. This method was critically compared with other chromatographic procedures used for quantification of S-substituted cysteine derivatives, namely with two other HPLC methods (derivatization by o-phthaldialdehyde/tert-butylthiol and fluorenylmethyl chloroformate), and with determination by gas chromatography or capillary electrophoresis. Major advantages and drawbacks of these analytical procedures are discussed. Employing these various chromatographic methods, the content and relative proportions of individual S-substituted cysteine derivatives were determined in four most frequently consumed alliaceous vegetables (garlic, onion, shallot, and leek).

Pregnant women tend to experience anxiety and stress when faced with the changes to their biology, environment and personal relationships. The identification of these factors and the prevention of their side effects are vital for both mother and fetus. The present study was conducted to validate and to examine the factor structure of the Persian version of the Pregnancy's Worries and Stress Questionnaire. The 25-item PWSQ was first translated by specialists into Persian. The questionnaire's validity was determined using face, content, criterion and construct validity and reliability of questionnaire was examined using Cronbach's alpha. Confirmatory factor analysis was performed in AMOS and SPSS 21. Participants included healthy Iranian pregnant women (8-39 weeks) who refer to selected hospitals for prenatal care. Hospitals included private, social security and university hospitals and selected through the random cluster sampling method. The results of validity and reliability assessments of the questionnaire were acceptable. Cronbach's alpha calculated showed a high internal consistency of 0.89. The confirmatory factor analysis using the c2, CMIN/DF, IFI, CFI, NFI and NNFI indexes showed the 6-factor model to be the best fitted model for explaining the data. The questionnaire was translated into Persian to examine stress and worry specific to Iranian pregnant women. The psychometric results showed that the questionnaire is suitable for identifying Iranian pregnant women with pregnancy-related stress.

Moon Phases Over the Persian Gulf

NASA images acquired October 15, 2012 The Visible Infrared Imaging Radiometer Suite (VIIRS) on the Suomi NPP satellite captured these nighttime views of the Persian Gulf region on September 30, October 5, October 10, and October 15, 2012. The images are from the VIIRS “day-night band,” which detects light in a range of wavelengths from green to near-infrared and uses filtering techniques to observe signals such as gas flares, auroras, wildfires, city lights, and reflected moonlight. Each image includes an inset of the Moon in four different phases. September 30 shows the Persian Gulf by the light of the full Moon; October 15 shows the effects of a new Moon. As the amount of moonlight decreases, some land surface features become harder to detect, but the lights from cities and ships become more obvious. Urbanization is most apparent along the northeastern coast of Saudi Arabia, in Qatar, and in the United Arab Emirates (UAE). In Qatar and UAE, major highways can even be discerned by nighttime lights. In eighteenth-century England, a small group of entrepreneurs, inventors and free thinkers—James Watt and Charles Darwin’s grandfathers among them—started a club. They named it the Lunar Society, and the “lunaticks” scheduled their dinner meetings on evenings of the full Moon. The timing wasn’t based on any kind of superstition, it was based on practicality. In the days before electricity, seeing one’s way home after dark was far easier by the light of a full Moon. In the early twenty-first century, electricity has banished the need for such careful scheduling, but the light of the full Moon still makes a difference.

Tuberculosis is one of the major public health problems faced globally. Resistance of Mycobacterium tuberculosis to antitubercular agents has called for an urgent need to investigate newer drugs to combat tuberculosis. Garlic (Allium sativum) is an edible plant which has generated a lot of curiosity throughout human history as a medicinal plant. Garlic contains sulfur compounds like allicin, ajoene, allylmethyltrisulfide, diallyltrisulfide, diallyldisulphide and others which exhibit various biological properties like antimicrobial, anticancer, antioxidant, immunomodulatory, antiinflammatory, hypoglycemic, and cardiovascular effects. According to various traditional systems of medicine, garlic is one of the established remedies for tuberculosis. The objective of the current study was to investigate in vitro antimycobacterial activity as well as anti-bacterial activity of various extracts rich in specific phytoconstituents from garlic. Preparation of garlic extracts was done based on the chemistry of the constituents and their stability. The estimation of in vitro antimycobacterial activity of different garlic extracts was done using Resazurin microtire plate assay technique whereas activity of garlic oil was evaluated by colony count method. The antibacterial activity of extracts and oil was estimated by zone of inhibition method. Extracts of garlic rich in allicin and ajoene showed appreciable antimycobacterial activity as compared to standard drugs. Garlic oil demonstrated significant antibacterial activity, particularly against methicillin-resistant Staphylococcus aureus. PMID:25035540

Molecular mechanism regulated by auxin and cytokinin during endoreduplication, cell division, and elongation process is studied by using Allium cepa roots as a model system. The activity of CDK genes modulated by auxin and cytokinin during cell division, elongation, and endoreduplication process is explained in this research work. To study the significance of auxin and cytokinin in the management of cell division and endoreduplication process in plant meristematic cells at molecular level endoreduplication was developed in root tips of Allium cepa by giving colchicine treatment. There were inhibition of vegetative growth, formation of c-tumor at root tip, and development of endoreduplicated cells after colchicine treatment. This c-tumor was further treated with NAA and BAP to reinitiate vegetative growth in roots. BAP gave positive response in reinitiation of vegetative growth of roots from center of c-tumor. However, NAA gave negative response in reinitiation of vegetative growth of roots from c-tumor. Further, CDKs gene expression analysis from normal, endoreduplicated, and phytohormone (NAA or BAP) treated root tip was done and remarkable changes in transcription level of CDK genes in normal, endoreduplicated, and phytohormones treated cells were observed.

Allium sativum L. (A.S.) "garlic", one of the most interesting medicinal plants, has been suggested to contain compounds that could be beneficial in numerous pathological situations including cancer. In this work, we aimed to assess the immunomodulatory effect of A.S. preparation on human peripheral blood mononuclear cells from healthy individuals. Nontoxic doses of A.S. were identified using MTT assay. Effects on CD4+ or CD8+ T lymphocyte proliferation were studied using flow cytometry. The effect of A.S. on cytokine gene expression was studied using qRT-PCR. Finally, qualitative analysis of A.S. was performed by HPLC approach. Data were analyzed statistically by one-way ANOVA test. The nontoxic doses of A.S. preparation did not affect neither spontaneous nor TCR-mediated CD4+ or CD8+ T lymphocyte proliferation. Interestingly, A.S. exhibited a statistically significant regulation of IL-17 gene expression, a cytokine involved in several inflammatory and autoimmune diseases. In contrast, the expression of IL-4, an anti-inflammatory cytokine, was unaffected. Qualitative analysis of A.S. ethanol preparation indicated the presence of three polyphenol bioactive compounds, which are catechin, vanillic acid and ferulic acid. The specific inhibition of the pro-inflammatory cytokine, IL-17 without affecting cell proliferation in human PBMCs by the Allium sativum L. preparation suggests a potential valuable effect of the compounds present in this plant for the treatment of inflammatory diseases and cancer, where IL-17 is highly expressed. The individual contribution of these three compounds to this global effect will be assessed.

To cross-culturally adapt of Persian Vocal Tract Discomfort (VTDp) scale and evaluate its validity and reliability in the assessment of patients with muscle tension dysphonia (MTD). A cross-sectional and prospective cohort design was used to psychometrically test the VTDp. The VTD scale was cross-culturally adapted into Persian language following standard forward-backward translations. The VTDp scale was administrated to 100 patients with MTD (54 men and 46 women; mean age: 38.05 ± 10.02 years) and 50 healthy volunteers (26 men and 24 women; mean age: 36.50 ± 12.27 years). Forty-five patients with MTD completed the VTDp 7 days later for test-retest reliability. Patients also completed the Persian Voice Handicap Index (VHIp) to assess construct validity. The results of discriminative validity demonstrated that the VTDp was able to discriminate between patients with MTD and healthy participants. The internal consistency was confirmed with Cronbach α .77 and 0.73 for VTDp frequency and severity subscales, respectively. The test-retest reliability was excellent with an intraclass correlation coefficient (ICC agreement ) of 0.93 for the frequency subscale and 0.91 for the severity subscale. Construct validity of the VTDp was shown with significant correlations between the VTDp frequency and severity subscales and the VHIp total scores (0.36 and 0.37, respectively). The standard error of measurement and smallest detectable change values for VTDp frequency (2.11 and 5.85, respectively) and severity (2.25 and 6.23, respectively) were acceptable. The Bland-Altman analysis for assessing the agreement between test and retest measurements showed no systematic bias. The VTDp is a valid and reliable self-administered scale to measure patient's vocal tract sensations in Persian-speaking population. Copyright © 2016 The Voice Foundation. Published by Elsevier Inc.

Background: Our hearing ability in space is critical for hearing speech in noisy environment and localization. The Spatial Hearing Questionnaire (SHQ) has been devised to focus only on spatial haring tasks (e.g., lateralization, distance detection and binaural detection). The aim of the present study was to determine the reliability and validity of the Persian translation of the SHQ (Spatial Hearing Questionnaire). Methods: Translation and back-translation, reliability, content and construct validity were investigated. Eighty patients with sensory neural hearing loss (SNHL) (52.50% female and 47.5 % male) with the mean±SD age of 49.02±13.60 years completed SHQ, and they were categorized into mild, moderate, moderate to severe and severe groups based on their hearing threshold. Inclusion criteria in this study were the MMSE questionnaire score of higher than 21, good general health, no history of psychiatric disorders, dizziness or vertigo, dementia or alcohol abuse. Results: The reliability was assessed by Cronbach’s alpha and found to be 0.99. Item-total correlation was between r= 0.84 and 0.92. There was a significant difference between the mean score of PSHQ in the four groups. Based on the factor analysis, two factors were extracted from the questions in P-SHQ: sound localization; and music and speech understanding in noise and quiet. These factors could explain 82.1% and 9.3% of the total variance, respectively. Conclusion: The present study proved the reliability and validity of the Persian version of SHQ (PSHQ). This provides a suitable tool for spatial hearing assessment in clinical/research environments. PMID:26793624

Previous studies have highlighted that narrative skill is critical to the development of the literacy skills by children. Children with cochlear implants (CI) and hearing aids (HA) may have problems in narrative development compared to peers with healthy hearing (HH). There is no exact data about the narrative writing ability of Persian-speaking students who are hearing-impaired. This study was undertaken to compare the microstructure and macrostructure scores for narrative writing of Persian-speaking students who are hearing-impaired and peers with HH. This was a cross-sectional descriptive-analytical study. The subjects were recruited from elementary schools in the city of Tehran. A total of 144 elementary school students were participated. The written narratives were elicited using a wordless pictorial storybook story. Three-way ANOVA with post hoc adjusted Bonferroni test was applied to determine the main effects and interactions of grounded variables on the microstructure and macrostructure components of narrative writing. No significant differences were observed in the macrostructure components of narrative writing between hearing-impaired and HH students. Factors analysis showed that the 4th grade HH students had significantly the highest scores, and the 3rd grade HA students had significantly the lowest scores in microstructure components of narrative writing. The findings revealed that hearing-impaired students similarly to their HH peers can transmit the main idea (macrostructure) of narrative writing, but show critical difficulties when using complete grammatical elements (microstructures) to form sentences to convey the idea in the narrative. © 2018 John Wiley & Sons Ltd.

Alternaria from different Allium plants was characterized by multilocus sequence analysis. Based on sequences of the β-tubulin (BT2b), the Alternaria allergen a1 (Alt a1), and the RNA polymerase II second largest subunit (RPB2) genes and phylogenetic data analysis, isolates were divided into two groups. The two groups were identical to representative isolates of A. porri (EGS48-147) and A. vanuatuensis (EGS45-018). The conidial characteristics and pathogenicity of A. vanuatuensis also well supported the molecular characteristics. This is the first record of A. vanuatuensis E. G. Simmons & C. F.

The Iranian Persian chub is an endemic species of the family Cyprinidae known only from few localities in drainages of Southern Iran. It was originally described in the genus Pseudophoxinus as (Pseudophoxinus persidis) and then Petroleuciscus (as Petroleuciscus persidis). In this study, we examined phylogenetic relationships of the Iranian Persian chub with other relatives in the family Cyprinidae based on the mitochondrial cytochrome b gene to estimate the phylogenetic (and taxonomic) position of the species. Our molecular phylogenies show that new fish sequences from the drainages in southern Iran are clustered with sequences of the genus Acanthobrama from GenBank while the sequences from two other genera (Pseudophoxinus and Petroleuciscus) are in distinct clade. Therefore, we conclude that the populations of Persian Chub in drainages of southern Iran (i.e., Kol, Kor, Maharlu and Persis) belong to the genus Acanthobrama and species Acanthobrama persidis. The predicted geographic distributions for the species showed a large area of suitable climate for A. persidis across south and west of Iran especially in the Kor River basin. Some other parts in the Persis and Tigris are also might have been suitable habitats for this cyprinid species showing possible dispersal route of Acanthobrama from Tigris to the Persis, Kor and Kol basins.

Veratrum album (white or false hellebore) is a poisonous plant containing steroidal alkaloids that cause nausea, vomiting, headache, visual disturbances, paresthesia, dizziness, bradycardia, atrioventricular block, hypotension, and syncope. It is regularly mistaken for Gentiana lutea (yellow gentian). We report accidental poisoning with V. album mistaken for Allium ursinum (wild garlic), a wild plant used in soups and salads in Central Europe. Four adults (24-45 years) accidentally ingested V. album mistaken for A. ursinum in self-prepared salads and soups. Within 15-30 min of ingestion they developed nausea, vomiting, and abdominal pain. At the same time dizziness, tingling, dimmed and jumping vision, transient blindness, and confusion appeared. On arrival at the ED, all patients had sinus bradycardia and hypotension. Following treatment the patients were discharged well 24-48 h after ingestion. In patients presenting with gastrointestinal, neurological, and cardiovascular symptoms a history of wild plant ingestion suggests possible poisoning with V. album mistaken for wild garlic.

Predicting time to relapse provides an opportunity for the development of relapse prevention interventions in drug users. The aim of the present study was to describe the development of the Persian version of the 9-item Time to Relapse Questionnaire (TRQ) and to evaluate its psychometric properties in an Iranian sample of treatment-seeking individuals with substance dependence (n = 150). The forward-backward method was used to translate the TRQ scale from English into Persian. After linguistic validation and a pilot check, a cross-sectional study was performed, and psychometric properties of the Iranian version of the questionnaire were assessed. The reliability was evaluated by Cronbach's alpha and test-retest analyses. In addition, the factor structure of the scale was extracted by applying confirmatory factor analysis. The mean age of participants was 40.52 (SD = 11.30) years. The mean scores for the content validity index (CVI) and the content validity ratio (CVR) were 0.93 and 0.81, respectively. A confirmatory factor analysis (CFA) demonstrated that the three-factor model of the TRQ was a good fit for the data and thus replicated the factor structure of the original English language TRQ. Cronbach's alpha presented good internal consistency (alpha = 0.76), and test-retest reliability of the TRQ instrument with 2-week intervals was appropriate (ICC = 0.84). The findings demonstrate that the Persian version of the TRQ is a reliable and valid scale for measuring time to relapse in Iranian drug users. The TRQ can be applied at the start of treatment so that clinical interventions can be targeted toward the different relapse styles.

Onion (Allium cepa L.) is one of the most commonly cultivated crops across the globe, and its production is increasing every year due to increasing consumer demand. Simultaneously, huge amounts of waste are produced from different parts of the onion, which ultimately affect the environment in various ways. Hence, proper usage as well as disposal of this waste is important from the environmental aspect. This review summarizes various usage methods of onion waste material, and processes involved to achieve maximum benefits. Processing industries produce the largest amount of onion waste. Other sources are storage systems, domestic usage and cultivation fields. Particular emphasis has been given to the methods used for better extraction and usage of onion waste under specific topics: viz. organic synthesis, production of biogas, absorbent for pollutants and value added products.

The Dichotic Verbal Memory Test (DVMT) is useful in detecting verbal memory deficits and differences in memory function between the brain hemispheres. The purpose of this study was to prepare the Persian version of DVMT, to obtain its results in 18- to 25-yr-old Iranian individuals, and to examine the ear, gender, and serial position effect. The Persian version of DVMT consisted of 18 10-word lists. After preparing the 18 lists, content validity was assessed by a panel of eight experts and the equivalency of the lists was evaluated. Then the words were recorded on CD in a dichotic mode such that 10 words were presented to one ear, with the same words reversed simultaneously presented to the other ear. Thereafter, it was performed on a sample of young, normal, Iranian individuals. Thirty normal individuals (no history of neurological, ontological, or psychological diseases) with ages ranging from 18 to 25 yr were examined for evaluating the equivalency of the lists, and 110 subjects within the same age range participated in the final stage of the study to obtain the normative data on the developed test. There was no significant difference between the mean scores of the 18 developed lists (p > 0.05). The mean content validity index (CVI) score was .96. A significant difference was found between the mean score of the two ears (p < 0.05) and between female and male participants (p < 0.05). The Persian version of DVMT has good content validity and can be used for verbal memory assessment in Iranian young adults. American Academy of Audiology.

Abstract The Persian Gulf is known as the westernmost distribution limit for sea snakes, except for Hydrophis platurus (Linnaeus, 1766) that reaches southeastern Africa. Previous identification guides for sea snakes of the Persian Gulf and its adjacent waters in the Gulf of Oman were based on old data and confined mostly to written descriptions. Therefore, a series of field surveys were carried out in 2013 and 2014 through Iranian coastal waters of both gulfs to provide a comprehensive sampling of sea snakes in the area. This paper presents an illustrated and updated checklist and identification tool for sea snakes in the Persian Gulf and Gulf of Oman, which are based on new material and a review of the literature. This checklist includes ten species of marine hydrophiines, of which one, Microcephalophis cantoris (Günther, 1864), is a new record for the area. All specimens examined herein are deposited and available at the Zoological Museum of Shahid Bahonar University of Kerman, Kerman province, Iran. PMID:27843383

Genotoxic effects of bromoform and chloroform, disinfection by-products of the chlorination of drinking water, were examined by using mitotic index (MI), mitotic phase, chromosome aberrations (CAs) and comet assay on root meristematic cells of Allium cepa. Different concentrations of bromoform (25, 50, 75 and 100 μg/mL) and chloroform (25, 50, 100 and 200 μg/mL) were introduced to onion tuber roots. Distilled water was used as a negative control and methyl methansulfonate (MMS-10 μg/mL) as positive control. All obtained data were subjected to statistical analyses by using SPSS 15.0 for Windows software. For comparison purposes, Duncan multiple range tests by using one-way analysis of variance were employed and p < 0.05 was accepted as significant value. Exposure of both chemicals (except 25 μg/mL applications of bromoform) significantly decreased MI. Bromoform and chloroform (except 25 μg/mL applications) increased total CAs in Allium anaphase-telophase test. A significant increase in DNA damage was also observed at all concentrations of both bromoform and chloroform examined by comet assay. The damages were higher than that of positive control especially at 75-100 μg/mL for bromoform and 100-200 μg/mL for chloroform.

With the spread of websites, especially those related to health issues, the number of their visitors also increases, more than half of which are about nutritional information. Therefore, quality analysis of nutrition and diet therapy websites is of outmost importance. This study aims to evaluate the quality of Persian nutrition and diet therapy websites. The current work is a survey study and uses an applied study method. The statistical population consists of 51 Persian websites about nutrition and diet therapy and census method was used in order to study them. Data gathering was done using a checklist and with direct visit to each website. Descriptive and analytical statistics were used to analyse the gathered data with the help of SPSS 21 software. Findings showed that content (66.7%), organization (82.4%), user friendly interfaces (52.9%) and total quality (70.6%) of most websites had a mediocre score while the design score for most of the websites (70.6%) was acceptable also organizational websites had better design, organization and quality compared to private websites. The three websites with the highest general quality score were the websites of "Novel Diet Therapy," "Behsite" and "Dr. BehdadiPour" (jointly) and "Dr. Kermani" respectively. Also in the dimension of content the factors of goal, relevance and credibility, in the dimension of design the factors of color, text and sound, pictures and videos, in the dimension of organization the factors of stability and indexing and in the dimension of user friendliness the factors of confidentiality, credibility and personalization had the highest scores. The results showed that the design score was higher than other scores. Also the general quality score of the websites was mediocre and was not desirable. Also websites didn't have suitable scores in every factor. Since most people search the internet for nutritional and diet

In medical sciences, commitment to lifelong learning has been expressed as an important element. Today, due to the rapid development of medical information and technology, lifelong learning is critical for safe medical care and development in medical research. JeffSPLL is one of the scales for measuring lifelong learning among the staff of medical sciences that has never been used in Iran. The aim of the present study was to determine the factor structure and reliability of the Persian version of JeffSPLL among Persian-speaking staff of universities of medical sciences in Iran. This study was a cross-sectional study, methodologically, that was conducted in 2012-2013. In this study, 210 staff members of Birjand University of Medical Sciences were selected. Data collection tool was the Persian version of JeffSPLL. To investigate the factor structure of this tool, confirmatory factor analysis was used and to evaluate the model fit, goodness-of-fit indices, root mean square error of approximation (RMSEA), the ratio of chi-square to the degree of freedom associated with it, comparative fit index (CFI), and root mean square residual (RMR) were used. To investigate the reliability of tool, Cronbach's alpha was employed. Data analysis was conducted using LISREL8.8 and SPSS 20 software. Confirmatory factor analysis showed that RMSEA was close to 0.1, and CFI and GFI were close to one. Therefore, four-factor model was appropriate. Cronbach's alpha was 0.92 for the whole tool and it was between 0.82 and 0.89 for subscales. The present study verified the four-factor structure of the 19-item Persian version of JeffSPLL that included professional learning beliefs and motivation, scholarly activities, attention to learning opportunities, and technical skills in information seeking among the staff. In addition, this tool has acceptable reliability. Therefore, it was appropriate to assess lifelong learning in the Persian-speaking staff population.

Microsporogenesis in garlic. The male-sterile Allium sativum (garlic) reproduces exclusively in the vegetative mode, and anthropogenic factors seem to be the cause of the loss of sexual reproduction capability. There are many different hypotheses concerning the causes of male sterility in A.sativum; however, the mechanisms underlying this phenomenon have not been comprehensively elucidated.Numerous attempts have been undertaken to understand the causes of male sterility, but the tubulin cytoskeleton in meiotically dividing cells during microsporogenesis has never been investigated in this species. Using sterile A.sativum genotype L13 and its fertile close relative A. ampeloprasum (leek), we have analysed the distribution of the tubulin cytoskeleton during microsporogenesis. We observed that during karyokinesis and cytokinesis, in both meiotic divisions I and II, the microtubular cytoskeleton in garlic L13 formed configurations that resembled tubulin arrangement typical of monocots. However, the tubulin cytoskeleton in garlic was distinctly poorer (composed of a few MT filaments) compared with that found in meiotically dividing cells in A. ampeloprasum. These differences did not affect the course of karyogenesis, chondriokinesis, and cytokinesis, which contributed to completion of microsporogenesis, but there was no further development of the male gametophyte. At the very beginning of the successive stage of development of fertile pollen grains, i.e. gametogenesis, there were disorders involving the absence of a normal cortical cytoskeleton and dramatically progressive degeneration of the cytoplasm in garlic. Therefore,we suggest that, due to disturbances in cortical cytoskeleton formation at the very beginning of gametogenesis, the intracellular transport governed by the cytoskeleton might be perturbed, leading to microspore decay in the male-sterile garlic genotype.

Epidemiologic studies support the premise that Allium vegetables may lower the risk of cancers. The beneficial effects appear related to the organosulfur products generated upon processing of Allium. Leukemia cells from patients with acute myeloid leukemia (AML) display high proliferative capacity and have a reduced capacity of undergoing apoptosis and maturation. Whether the sulfur-containing molecules thiosulfinates (TS), diallyl TS (All(2)TS), dipropyl TS (Pr(2)TS) and dimethyl TS (Me(2)TS), are able to exert chemopreventative activity against AML is presently unknown. The present study was an evaluation of proliferation, cytotoxicity, differentiation and secretion of AML cell lines (U937, NB4, HL-60, MonoMac-6) in response to treatment with these TS and their related sulfides (diallylsulfide, diallyl disulfide, dipropyl disulfide, dimethyl disulfide). As assessed by flow cytometry, ELISA, gelatin zymogaphy and RT-PCR, we showed that Pr(2)TS and Me(2)TS, but not All(2)TS and sulfides, 1) inhibited cell proliferation in dose- and time-dependent manner and this process was neither due to cytotoxicity nor apoptosis, 2) induced macrophage maturation, and 3) inhibited the levels of secreted MMP-9 (protein and activity) and TNF-alpha protein, without altering mRNA levels. By establishing for the first time that Pr(2)TS and Me(2)TS affect proliferation, differentiation and secretion of leukemic cell lines, this study provides the opportunity to explore the potential efficiency of these molecules in AML.

Self-efficacy plays a key role in varying areas of human conditions which can be measured by different scales. The present study was aimed to evaluate the psychometric properties of Moorong Self-Efficacy Scale (MSES) in Iranian Subjects with Physical Disability (SWPD). Data were collected by face-to-face interviews and self-report surveys from 214 subjects. The face and content validity, and reliability were evaluated. Discriminates were evaluated between the sub-groups of disability levels, physical activity, and health condition levels. The concurrent, convergent, divergent, and construct validity were assessed by short form health survey scale (SF-36), general self-efficacy scale (GSES), hospital anxiety and depression scale (HADS), respectively. Replaceable exploratory factor analysis was evaluated. SPSS software was used for statistical analysis. There were acceptable face and content validity, and reliability. Furthermore, significant correlation was found between PSES and SF-36 (p < 0.001). Self-efficacy was statistically different among the disability levels (p = 0.02), physical activity levels (p < 0.001), and health status (p = 0.001). The correlation of Persian Self-Efficacy Scale (PSES) scores with GSES (r = 0.61, p < 0.001), and HADS (R = -0.53, p < 0.001) was significant. This scale yielded a two-dimensional structure, with a good internal replicability. The external replicability was satisfactory when we compared factor loadings with the original study. The PSES is a valid, reliable and sensitive tool to measure the self-efficacy among SWPD for planning and managing of disability problems. Implications for rehabilitation Psychometric properties of the Persian version of self-Efficacy scale (PSES) appear to be similar to original, English version. The PSES has been shown to have validity and reliability in Persian physical disables and can be used for patients with more different types of physical disability than

To replenish the depleting populations of sturgeon fishes especially Persian sturgeon, Acipenser persicus in the Caspian Sea, millions of Persian sturgeon fingerlings are farmed through artificial propagation and released into the Iranian river estuaries annually. Fish osmoregulation is a vital physiological process that can be affected during the release. Many Iranian river estuaries are under the influence of pesticides originating from farming activities that may affect osmoregulation. In this study, Persian sturgeon fingerlings were exposed to sublethal concentrations (0, 0.18, 0.54, 0.9mgL(-)(1)) of diazinon for 96h (short-term trial) and 12 days (long-term trial) in fresh water (FW) and then fish were exposed in brackish water (BW) for 24h. After 96h and 12 days of exposure in FW, the lower levels of plasma triidothyronine (T3), thyroxine (T4), Na(+), Cl(-), K(+), gill Na(+)/K(+)- ATPase activity and number of chloride cells were observed in exposed fish (0.54 and 0.9mgL(-)(1) diazinon) compared to control group and 0.18mgL(-)(1) diazinon treatment. Also, higher levels of plasma cortisol (except 0.18mgL(-)(1) diazinon treatment in long-term trial) were observed in diazinon exposed fish compared to control group. However, gill Na(+)/K(+)-ATPase activity and the number of chloride cells were higher in fingerlings exposed to diazinon compared than control. When fish were exposed in BW for 24h, the following changes occurred: (a) in short-term trial: increases in cortisol and Cl(-) levels (0.54mgL(-)(1) diazinon ), Na(+) (0.9mgL(-)(1) diazinon ) and gill Na(+)/K(+)-ATPase activity (0.18mgL(-)(1) diazinon ). In control group, cortisol, T4, Na(+), gill Na(+)/K(+)-ATPase activity and the number of chloride cells increased significantly. (b) In long-term trial: increases in K(+) levels in fish exposed to 0.9mgL(-)(1) diazinon, Na+ in all diazinon concentrations and decreases in chloride cells number in fish exposed to 0.18mgL(-)(1) diazinon. In control group

After gas chromatography and mass spectrometry of prepared methanolic extract of Allium sativum, 40 laboratory BALB/c mice were infected intraperitoneally by injection of 1,500 viable protoscoleces. Five months after infection, the infected mice were allocated into four treatment groups, including 1- Albendazole (100 mg/kg); 2- Allium sativum methanolic extract (10 mL/L); 3- A. sativum methanolic extract (10 mL/L) + Albendazole (50 mg /kg); and 4- untreated control group. After 30 days of daily treatment, total number and weight of cysts and size of the largest cyst as well as blood serum bilirubin and liver enzymes were compared between the mice of different groups. The total number and weight of cysts and size of the largest cyst were significantly lower in treated groups A. sativum 10 mL/L + Albendazole 50 and Albendazole 100 in comparison to those of the control group (p < 0.05). The activity of alanine aminotransferase (ALT) enzyme and bilirubin concentration were significantly lower in the mice treated with A. sativum 10 mL/L and A. sativum 10 mL/L + Albendazole 50, when compared to the control group. In addition, bilirubin concentration revealed significant decrease in A. sativum 10 mL/L and A. sativum 10 mL/L + Albendazole 50 groups, when compared to the Albendazole group. In conclusion, administration of A. sativum 10 mL/L improved the anti-hydatidosis activity of Albendazole 50 mg /kg, due to parasitological effects similar to Albendazole 100 mg /kg but less hepatotoxic effects.

Garlic (Allium sativum), an important medicinal spice, displays a plethora of biological effects including immunomodulation. Although some immunomodulatory proteins from garlic have been described, their identities are still unknown. The present study was envisaged to isolate immunomodulatory proteins from raw garlic, and examine their effects on certain cells of the immune system (lymphocytes, mast cells, and basophils) in relation to mitogenicity and hypersensitivity. Three protein components of approximately 13 kD (QR-1, QR-2, and QR-3 in the ratio 7:28:1) were separated by Q-Sepharose chromatography of 30 kD ultrafiltrate of raw garlic extract. All the 3 proteins exhibited mitogenic activity towards human peripheral blood lymphocytes, murine splenocytes and thymocytes. The mitogenicity of QR-2 was the highest among the three immunomodulatory proteins. QR-1 and QR-2 displayed hemagglutination and mannose-binding activities; QR-3 showed only mannose-binding activity. Immunoreactivity of rabbit anti-QR-1 and anti-QR-2 polyclonal antisera showed specificity for their respective antigens as well as mutual cross-reactivity; QR-3 was better recognized by anti-QR-2 (82%) than by anti-QR-1 (55%). QR-2 induced a 2-fold higher histamine release in vitro from leukocytes of atopic subjects compared to that of non-atopic subjects. In all functional studies, QR-2 was more potent compared to QR-1. Taken together, all these results indicate that the two major proteins QR-2 and QR-1 present in a ratio of 4:1 in raw garlic contribute to garlic's immunomodulatory activity, and their characteristics are markedly similar to the abundant Allium sativum agglutinins (ASA) I and II, respectively.

The fouling barnacle Amphibalanus amphitrite is a cosmopolitan biomonitor of trace metal bioavailabilities, with an international comparative data set of body metal concentrations. Bioavailabilities of As, Cd, Cr, Cu, Fe, Mn, Pb, V and Zn to A. amphitrite were investigated at 19 sites along the Iranian coast of the understudied Persian Gulf. Commercial and fishing ports showed extremely high Cu bioavailabilities, associated with high Zn bioavailabilities, possibly from antifouling paints and procedures. V availability was raised at one port, perhaps associated with fuel leakage. Cd bioavailabilities were raised at sites near the Strait of Hormuz, perhaps affected by adjacent upwelling off Oman. The As data allow a reinterpretation of the typical range of accumulated As concentrations in A. amphitrite. The Persian Gulf data add a new region to the A. amphitrite database, confirming its importance in assessing the ecotoxicologically significant trace metal contamination of coastal waters across the world.

We investigated whether Persian Gulf War veterans (GWVs) were more likely than Persian Gulf War-era veterans deployed elsewhere (GEVs) to have noncredible neuropsychological examinations. A total of 301 GWVs and 99 GEVs underwent neuropsychological testing. The credibility of 173 examinations showing impairment was evaluated based on test performances, clinical background, psychometric measures, and other self-report data. All 11 examinations judged less than fully credible by one neuropsychologist, plus 19 examinations judged impaired but credible, were then evaluated independently by two more neuropsychologists. Noncredibility was judged with excellent reliability (93% agreement). Seven examinations were judged noncredible. Rates of noncredibility did not differ between GWVs (1%) and GEVs (4%). The pattern of associations of noncredible examinations with cognitive, psychological, and clinical variables generally indicated defective neuropsychological scores, with no coherent pattern, and personality disorder. Findings supported the validity of noncredibility judgments and suggested that noncredible examinations are not a significant problem in neuropsychological investigations of GWVs.

Alternaria from different Allium plants was characterized by multilocus sequence analysis. Based on sequences of the β-tubulin (BT2b), the Alternaria allergen a1 (Alt a1), and the RNA polymerase II second largest subunit (RPB2) genes and phylogenetic data analysis, isolates were divided into two groups. The two groups were identical to representative isolates of A. porri (EGS48-147) and A. vanuatuensis (EGS45-018). The conidial characteristics and pathogenicity of A. vanuatuensis also well supported the molecular characteristics. This is the first record of A. vanuatuensis E. G. Simmons & C. F. Hill from Korea and China. PMID:25606017

Reading skills are necessary for educational development in children. Many studies have shown that children with hearing loss often experience delays in reading. This study aimed to examine reading skills of Persian deaf children with cochlear implant and hearing aid and compare them with normal hearing counterparts. The sample consisted of 72 s and third grade Persian-speaking children aged 8-12 years. They were divided into three equal groups including 24 children with cochlear implant (CI), 24 children with hearing aid (HA), and 24 children with normal hearing (NH). Reading performance of participants was evaluated by the "Nama" reading test. "Nama" provides normative data for hearing and deaf children and consists of 10 subtests and the sum of the scores is regarded as reading performance score. Results of ANOVA on reading test showed that NH children had significantly better reading performance than deaf children with CI and HA in both grades (P < 0.001). Post-hoc analysis, using Tukey test, indicated that there was no significant difference between HA and CI groups in terms of non-word reading, word reading, and word comprehension skills (respectively, P = 0.976, P = 0.988, P = 0.998). Considering the findings, cochlear implantation is not significantly more effective than hearing aid for improvement of reading abilities. It is clear that even with considerable advances in hearing aid technology, many deaf children continue to find literacy a challenging struggle. Copyright © 2016 Elsevier Ireland Ltd.

The aims of the study were to translate into Persian and culturally adapt the Kessler Psychological Distress Scales, K10 and K6, and to assess their reliability and validity. The sample was recruited from primary health care (PHC) settings by quota nonprobability sampling, stratified by sex and age. Validity was assessed against the Composite International Diagnostic Interview (v2.1). The psychometric properties of K6 and K10 were also compared with the 12-item General Health Questionnaire (GHQ-12). A total of 818 participants completed the questionnaire. Cronbach's alpha were 0.92 and 0.87 for K6 and K10, respectively. Optimal cutoff scores for detecting any mood or anxiety disorder in the past 30 days were 15 for K10 and 10 for K6. At these cutoff points, the measures had sensitivities of 0.77 and 0.73, specificities of 0.74 and 0.78, and positive predictive values of 0.48 and 0.52, respectively. Psychometric properties of K10 and K6 were similar to GHQ-12. Persian K10 and K6 have acceptable psychometric properties as screening instruments for common mental health conditions. Given its brevity and similar psychometric properties to the longer instruments, the Persian K6 appears to be a suitable for use in PHC settings and, possibly, epidemiologic studies in Iran.

Background and Objectives: Pregnant women tend to experience anxiety and stress when faced with the changes to their biology, environment and personal relationships. The identification of these factors and the prevention of their side effects are vital for both mother and fetus. The present study was conducted to validate and to examine the factor structure of the Persian version of the Pregnancy’s Worries and Stress Questionnaire. Materials and Methods: The 25-item PWSQ was first translated by specialists into Persian. The questionnaire’s validity was determined using face, content, criterion and construct validity and reliability of questionnaire was examined using Cronbach’s alpha. Confirmatory factor analysis was performed in AMOS and SPSS 21. Participants included healthy Iranian pregnant women (8-39 weeks) who refer to selected hospitals for prenatal care. Hospitals included private, social security and university hospitals and selected through the random cluster sampling method. Findings: The results of validity and reliability assessments of the questionnaire were acceptable. Cronbach’s alpha calculated showed a high internal consistency of 0.89. The confirmatory factor analysis using the χ2, CMIN/DF, IFI, CFI, NFI and NNFI indexes showed the 6-factor model to be the best fitted model for explaining the data. Conclusion: The questionnaire was translated into Persian to examine stress and worry specific to Iranian pregnant women. The psychometric results showed that the questionnaire is suitable for identifying Iranian pregnant women with pregnancy-related stress. PMID:26153186

The aim of this study was to examine the role of audiovisual speech recognition as a clinical criterion of cochlear implant or hearing aid efficiency in Persian-language children with severe-to-profound hearing loss. This research was administered as a cross-sectional study. The sample size was 60 Persian 5-7 year old children. The assessment tool was one of subtests of Persian version of the Test of Language Development-Primary 3. The study included two experiments: auditory-only and audiovisual presentation conditions. The test was a closed-set including 30 words which were orally presented by a speech-language pathologist. The scores of audiovisual word perception were significantly higher than auditory-only condition in the children with normal hearing (P<0.01) and cochlear implant (P<0.05); however, in the children with hearing aid, there was no significant difference between word perception score in auditory-only and audiovisual presentation conditions (P>0.05). The audiovisual spoken word recognition can be applied as a clinical criterion to assess the children with severe to profound hearing loss in order to find whether cochlear implant or hearing aid has been efficient for them or not; i.e. if a child with hearing impairment who using CI or HA can obtain higher scores in audiovisual spoken word recognition than auditory-only condition, his/her auditory skills have appropriately developed due to effective CI or HA as one of the main factors of auditory habilitation.

To investigate the psychometric properties of the Persian version of Caregiver Burden Scale (CBS) in caregivers of patients with spinal cord injury. This is a cross-sectional study. After a forward-backward translation, the CBS was administered to 110 caregivers of patients with spinal cord injury (men = 60, women = 50). Factor structure was evaluated by confirmatory factor analysis. The Internal consistency and test-retest reliability of the CBS were examined using Cronbach's α and the intraclass correlation coefficient, respectively. Construct validity was assessed by examining the relationship among CBS and the World Health Organization Quality of Life, and the Beck Depression Inventory. The results of confirmatory factor analysis provided support for a five-factor model of CBS. All subscales of CBS revealed acceptable internal consistency (0.698-0.755), except for environment subscale (0.559). The CBS showed adequate test-retest reliability for its subscales (0.745-0.900). All subscales of CBS significantly correlated with both Beck Depression Inventory and World Health Organization Quality of Life, confirming construct validity. The Persian version of the CBS is a valid and reliable measure for assessing burden of care in caregivers of patients with spinal cord injury. Implications for Rehabilitation Spinal cord injury leads to depression, high levels of stress and diminished quality of life due to the high physical, emotional, and social burdens in caregivers. Persian version of the Caregiver Burden Scale is a valid and reliable tool for assessing burden in Iranian caregivers of patients with spinal cord injury.

The present article aimed to compile information on the nutritional management for geriatric people. Popular textbooks of Persian medicine from 10th to 18th century were studied to derive relative viewpoints and considerations. The temperament, which is defined as the combination of 4 main elements (fire, air, water, and soil) and 4 humors made subsequently (black bile, yellow bile, phlegm, and blood), changes during age periods. Imbalance in proportional amounts of humors in elderly should be corrected with food and medicaments having opposite nature to the current condition. Traditional foods included mostly well-cooked soups, pottages, and porridges containing fresh sheep or chicken meat. Mono-ingredient foods were also administered according to their medical properties. Nutritional recommendations were also concerned with geriatrics' physiological conditions such as constipation, sleep disorders, and memory deficits. Many of traditional geriatric nutritional requirements are relevant in the present day. However, there are still notes that may be beneficial for consideration. © The Author(s) 2014.

Comparison of multiple methods for the determination of sulphite in Allium and Brassica vegetables

PubMed Central

Robbins Carlos, Katherine S.; de Jager, Lowri S.

2018-01-01

Sulphites are a family of additives regulated for use worldwide in food products. They must be declared on the label if they are present in concentrations greater than 10 mg kg−1, determined as sulphur dioxide (SO2). The current US regulatory method for sulphites, the optimised Monier–Williams method (OMW), produces false-positive results with vegetables from the Allium (garlic) and Brassica (cabbage) genera due to extraction conditions that are thought to cause endogenous sulphur compounds to release SO2. Recently, modifications to the OMW method (2× MW) were published that reportedly reduced this false-positive in garlic. However, no other vegetables from these genera have been investigated. In addition, an LC-MS/MS method was developed for sulphite analysis, but it has not yet been tested with these problematic matrices. Ten vegetable species were analysed using these sulphite methods (OMW titration, OMW gravimetric, 2× MW and LC-MS/MS) to determine the false-positive rate. Sulphite concentrations > 10 mg kg−1 SO2 were observed with the OMW analyses. The 2× MW method reduced the measured concentration in unsulphited samples to ≤ 10 mg kg−1 SO2 for all matrices analysed. The LC-MS/MS method showed concentrations < 10 mg kg−1 for the Brassica samples, but only displayed a slight reduction in the Allium matrices. Spiked recovery studies were conducted to determine if these methods can detect added sulphite. The 2× MW had recoveries of 17% and 42% for water and fresh garlic, respectively, and the LC-MS/MS had recoveries of 108%, 125%, 116% and 107% for water, fresh garlic, roasted garlic, and hummus, respectively. The low recoveries of the 2× MW may indicate that sulphur compounds cannot be properly quantified with this method. The ability to eliminate false-positives will enable accurate determination of added sulphite to ensure compliance with sulphite labelling requirements. PMID:27592824

During the Mesozoic most of the Arabian Peninsula, Persian Gulf, south-western Iran, and eastern Iraq constituted the Arabian platform. Deformation of the Musandam Peninsula in the Late Cretaceous and mid-Tertiary by compression (subduction) from the east and southwest, collision of the Arabian platform and Eurasian plate along the Zagros Crush zone during the Oligocene or early Miocene, and emplacement of the Zagros Mountains by gravitational sliding during the Neogene and Pleistocene have reduced the platform area to the Persian Gulf. Other factors that contributed to the reduction of the Arabian platform include the uplift of the Arabian Peninsula during the opening of the Red Sea in the Tertiary, tectonism of the Infracambrian Hormuz salt, upwarp of the platform sediment cover by basement uplift and/or salt tectonics, and a 600- to 400-m drop in sea level since the Cretaceous. At present, tectonism in the region is restricted to the northern edge of the Gulf of Oman where the Arabian plate is subducting the Eurasian plate from the south and to the Zagros Crush zone where the Arabian and Eurasian plates are colliding with one another.

In the early medieval era, in the time which is called the Islamic Golden Age, medicine flourished through the practice of Persian physicians (9th to 12th century AD). Abu-Sahl al-Masihi (died circa 1010 AD) was one of the physicians in that period who had great influence on the progress of medicine by his own writings as well as his influence on great scholars like Biruni and Avicenna as their teacher. He was a polymath and had many writings in various fields of science, in particular medical sciences. Some of his manuscripts in medicine were Al-Mia fil-Tibb (Book of the Hundred), Kitab al-Teb al-Koli (The General Medicine), Ezhar al-Hekmat Allah Ta'ala fi Khalgh al-Ensan (God's Mystery on the Creation of Man), Resalat al-Adwiya (Treatise of Drugs), Osool Elm Nabz (the Principles of Pulse), and Resala f ī Taḥqiq Amral-Waba' (On the determination of the matter of infectious diseases). As a sign of his impact in Persian medicine, many later physicians (until 19th century) referred to and cited his works in their manuscripts several times.

It seems that gene-environment interaction play most important role in Multiple Sclerosis development. Increasing the incidence and prevalence of MS during the recent decades in the low prevalence area such as Iran is explained better by environment factors. Environmental Risk Factors in Multiple Sclerosis (the 'EnvIMS-Q') is a 6-page self-administered questionnaire for case control studies. the objectives of study are validation and adaptation of the EnvIMS-Q' then development of a Persian version for case control studies in Persian population. This questionnaire translated literally and in culturally relevant form, then content validation process was done by three groups' experts. According to giving rating to each item, each section and the whole instrument, we calculated their content validation indexes and also added some new questions and a new section to EnvIMS-Q. Finally, we analyzed repeatability of the answers within a 4 weeks interval. Relevancy and clarity indexes of all items were more than 80%. Scale relevancy index equaled 99% and scale clarity index equaled 97%. Repeatability of most items was acceptable. the use of standardized validated questionnaires will assist the researchers to perform local studies on the role of environmental factors on the basis of reliable data.

he s Because there is no effective and safe drug therapy for hydatid cyst, finding of some new agents especially from herbal origin with a desired scolicidal effect attracts great attention for treatment and pre-surgical use to prevent the hydatid cyst recurrence. In this study, the scolicidal effect of ultrasonic methanol extract of Garlic (Allium sativum) flower is investigated. Protoscolices were collected aseptically from sheep livers containing hydatid cyst and were exposed to different concentrations of extract for various exposure times. The viability of protoscolices was confirmed by 0.1% Eosin staining. The scolicidal activity of extract at a concentration of 50 mg ml-1 was 59, 76, 81 and 86% after 10, 30, 60, and 180 min of exposure respectively. The scolicidal effect at 100 mg ml-1 was 67, 78, 85 and 98% after various exposure times, respectively. The results of this study showed that the ultrasonic extract has high scolicidal activity and might be used as a natural scolicidal agent. Garlic flower extracts is a potent protoscolicid and might be used in hydatid cyst treatment and pre-surgery to prevent secondary cyst recurrence.
