    Acacia senegal and Acacia seyal are small, deciduous legume trees, most highly valued for nitrogen fixation and for the production of gum arabic, a commodity of international trade since ancient times. Symbiotic nitrogen fixation by legumes represents the main natural input of atmospheric N2 into ecosystems which may ultimately benefit all organisms. We analyzed the nod and nif symbiotic genes and symbiotic properties of root-nodulating bacteria isolated from A. senegal and A. seyal in Senegal. The symbiotic genes of rhizobial strains from the two Acacia species were closed to those of Mesorhizobium plurifarium and grouped separately in the phylogenetic trees. Phylogeny of rhizobial nitrogen fixation gene nifH was similar to those of nodulation genes (nodA and nodC). All A. senegal rhizobial strains showed identical nodA, nodC, and nifH gene sequences. By contrast, A. seyal rhizobial strains exhibited different symbiotic gene sequences. Efficiency tests demonstrated that inoculation of both Acacia species significantly affected nodulation, total dry weight, acetylene reduction activity (ARA), and specific acetylene reduction activity (SARA) of plants. However, these cross-inoculation tests did not show any specificity of Mesorhizobium strains toward a given Acacia host species in terms of infectivity and efficiency as stated by principal component analysis (PCA). This study demonstrates that large-scale inoculation of A. senegal and A. seyal in the framework of reafforestation programs requires a preliminary step of rhizobial strain selection for both Acacia species.

    Rhizobial inoculation has been widely used in controlled conditions as a substitute for chemical fertilizers to increase plants growth and productivity. However, very little is known about such effects on mature trees in natural habitats. In this study, we investigated the effect of rhizobial inoculation on soil total microbial biomass, mineral nitrogen content, potential CO2 respiration, fluorescein diacetate (FDA), acid phosphatase activities, and gum arabic production by 13-year-old Senegalia senegal (synonym: Acacia senegal) under natural conditions in the north part of Senegal during two consecutive years. Rhizobial inoculation was performed at the beginning of the rainy season (July) for both years with a cocktail of four strains (CIRADF 300, CIRADF 301, CIRADF 302, and CIRADF 303). Rhizospheric soils were collected in both dry and rainy seasons to a depth of 0-25 cm under uninoculated and inoculated trees. Trees were tapped in November (beginning of dry season) using traditional tools. Gum arabic was harvested every 15 days from December to March. The results obtained from both years demonstrated that rhizobial inoculation increased significantly the percentage of trees producing gum arabic, gum arabic production per tree, soil microbial biomass, FDA, and acid phosphatase activities. However, there was no significant effect on C mineralization and mineral nitrogen (N) content. Gum arabic production was positively correlated to rainfall, soil microbial biomass, and mineral nitrogen content. Our results showed a positive effect of rhizobial inoculation on soil microbial functioning and gum arabic production by mature S. senegal trees. These important findings deserve to be conducted in several contrasting sites in order to improve gum arabic production and contribute to increase rural population incomes.

    Polyploidy is a common phenomenon in the evolution of angiosperms. It has been suggested that polyploids manage harsh environments better than their diploid relatives but empirical data supporting this hypothesis are scarce, especially for trees. Using microsatellite markers and flow cytometry, we examine the frequency of polyploids and diploids in a progeny trial testing four different populations of Acacia senegal, a species native to sub-Saharan regions of Africa. We compare growth between cytotypes and test whether polyploid seedlings grow better than diploids. Our results show that polyploids coexist with diploids in highly variable proportions among populations in Senegal. Acacia senegal genotypes were predominantly diploid and tetraploid, but triploid, pentaploid, hexaploid, and octaploid forms were also found. We find that polyploids show faster growth than diploids under our test conditions: in an 18 years old field trial, polyploid superiority was estimated to be 17% in trunk diameter and 9% in height while in a growth chamber experiment, polyploids grew 28% taller, but only after being exposed to drought stress. The results suggest that polyploid A. senegal can have an adaptive advantage in some regions of Africa. PMID:27379120

    Acacia senegal (L) Willd. and Acacia seyal Del. are highly nitrogen-fixing and moderately salt tolerant species. In this study we focused on the genetic and genomic diversity of Acacia mesorhizobia symbionts from diverse origins in Senegal and investigated possible correlations between the genetic diversity of the strains, their soil of origin, and their tolerance to salinity. We first performed a multi-locus sequence analysis on five markers gene fragments on a collection of 47 mesorhizobia strains of A. senegal and A. seyal from 8 localities. Most of the strains (60%) clustered with the M. plurifarium type strain ORS 1032T, while the others form four new clades (MSP1 to MSP4). We sequenced and assembled seven draft genomes: four in the M. plurifarium clade (ORS3356, ORS3365, STM8773 and ORS1032T), one in MSP1 (STM8789), MSP2 (ORS3359) and MSP3 (ORS3324). The average nucleotide identities between these genomes together with the MLSA analysis reveal three new species of Mesorhizobium. A great variability of salt tolerance was found among the strains with a lack of correlation between the genetic diversity of mesorhizobia, their salt tolerance and the soils samples characteristics. A putative geographical pattern of A. senegal symbionts between the dryland north part and the center of Senegal was found, reflecting adaptations to specific local conditions such as the water regime. However, the presence of salt does not seem to be an important structuring factor of Mesorhizobium species. PMID:25658650

    There is a strong association between cardiometabolic risk and adipose tissue dysfunction with great consequences on type 2 diabetic patients. Visceral Adiposity Index (VAI) is an indirect clinical marker of adipose tissue dysfunction. Gum Arabic (GA) is a safe dietary fiber, an exudate of Acacia Senegal. Gum Arabic had shown lipid lowering effect in both humans and animals. The aim of this trial was to determine the effect of GA supplementation on anthropometric obesity marker, Visceral Adiposity Index (VAI) and blood pressure in patients with type 2 diabetes mellitus. This randomized, double blinded, placebo controlled trial recruited a total of 91 type 2 diabetic patients (73 females, 18 males), age (mean ± SD) 50.09 ± 9.3 years on hypoglycemic agents and were randomly assigned into two groups, either to consume 30 g of GA or 5 g of placebo daily for 3 months. Anthropometric obesity markers were measured and indices were calculated. Blood pressure was measured and high density lipoprotein (HDL) and triglycerides (TG) were determined in fasting blood samples at the start and end of the study period. After intervention, Gum Arabic decreased BMI and VAI significantly (P < 0.05) in GA group by 2 and 23.7% respectively. Body adiposity index significantly decreased by 3.9% in GA group while there were no significant changes in waist circumference or waist-to-hip ratio (WHR). Systolic blood pressure significantly decreased by 7.6% in GA group and by 2.7% in placebo group from baseline with no significant changes in diastolic blood pressure in the two groups. Gum Arabic consumption at a dose of 30 g/d for 3 months may play an effective role in preventing weight gain and modulating adipose tissue dysfunction in type 2 diabetic patients, although no effect has been shown in waist-to-hip ratio. The trial had been registered as prospective interventional clinical trials in the Pan African Clinical Trial Registry (PACTR) PACTR201403000785219 , on 7th

  17. Matrix Assisted Laser Desorption Ionization Mass Fingerprinting for Identification of Acacia Gum in Microsamples from Works of Art.

    This paper reports an improved method for the identification of Acacia gum in cultural heritage samples using matrix assisted laser desorption ionization-time-of-flight mass spectrometry (MALDI-TOF MS) after enzymatic digestion of the polysaccharide component. The analytical strategy was optimized using a reference Acacia gum (gum arabic, sp. A. senegal) and provided an unambiguous MS profile of the gum, characterized by specific and recognized oligosaccharides, from as little as 0.1 μg of material. The enhanced experimental approach with reduced detection limit was successfully applied to the analysis of naturally aged (∼80 year) gum arabic samples, pure and mixed with lead white pigment, and allowed the detection of gum arabic in samples from a late painting (1949/1954) by Georges Braque in the collection of the Art Institute of Chicago. This first application of the technique to characterize microsamples from a painting, in conjunction with analyses by gas chromatography/mass spectrometry (GC/MS), provided important insights into Braque's unusual mixed paint media that are also helpful to inform appropriate conservation treatments for his works. The robustness of the analytical strategy due to the reproducibility of the gum MS profile, even in the presence of other organic and inorganic components, together with the minimal sample size required, demonstrate the value of this new MALDI-TOF MS method as an analytical tool for the identification of gum arabic in microsamples from museum artifacts.

  18. Anti-malarial effect of gum arabic

    PubMed Central

    2011-01-01

    Background Gum Arabic (GA), a nonabsorbable nutrient from the exudate of Acacia senegal, exerts a powerful immunomodulatory effect on dendritic cells, antigen-presenting cells involved in the initiation of both innate and adaptive immunity. On the other hand GA degradation delivers short chain fatty acids, which in turn have been shown to foster the expression of foetal haemoglobin in erythrocytes. Increased levels of erythrocyte foetal haemoglobin are known to impede the intraerythrocytic growth of Plasmodium and thus confer some protection against malaria. The present study tested whether gum arabic may influence the clinical course of malaria. Methods Human erythrocytes were in vitro infected with Plasmodium falciparum in the absence and presence of butyrate and mice were in vivo infected with Plasmodium berghei ANKA by injecting parasitized murine erythrocytes (1 × 106) intraperitoneally. Half of the mice received gum arabic (10% in drinking water starting 10 days before the day of infection). Results According to the in vitro experiments butyrate significantly blunted parasitaemia only at concentrations much higher (3 mM) than those encountered in vivo following GA ingestion (<1 μM). According to the in vivo experiments the administration of gum arabic slightly but significantly decreased the parasitaemia and significantly extended the life span of infected mice. Discussion GA moderately influences the parasitaemia and survival of Plasmodium-infected mice. The underlying mechanism remained, however, elusive. Conclusions Gum arabic favourably influences the course of murine malaria. PMID:21599958

    Rhizobial inoculation has a positive impact on plants growth; however, there is little information about its effect on soil microbial communities and their activity in the rhizosphere. It was therefore necessary to test the effect of inoculation of Acacia senegal (L.) Willd. seedlings with selected rhizobia on plant growth, structure and diversity of soil bacterial communities and soil functioning in relation to plant provenance and soil origin. In order to carry out this experiment, three A. senegal seeds provenance from Kenya, Niger, and Senegal were inoculated with selected rhizobial strains. They have been further grown during 4 months in greenhouse conditions in two non-disinfected soils, Dahra and Goudiry coming respectively from arid and semi-arid areas. The principal component analysis (ACP) showed an inoculation effect on plant growth, rhizospheric bacterial diversity and soil functioning. However, the performances of the rhizobial strains varied in relation to the seed provenance and the soil origin. The selected rhizobial strains, the A. senegal provenance and the soil origin have modified the structure and the diversity of soil bacterial communities as measured by principal component analysis/denaturing gradient gel electrophoresis analyses. It is interesting to note that bacterial communities of Dahra soil were highly structured according to A. senegal provenance, whereas they were structured in relation to rhizobial inoculation in Goudiry soil. Besides, the impact of inoculation on soil microbial activities measured by fluorescein diacetate analyses varied in relation to plant provenance and soil origin. Nevertheless, total microbial activity was about two times higher in Goudiry, arid soil than in Dahra, semi-arid soil. Our results suggest that the rhizobial inoculation is a suitable tool for improving plants growth and soil fertility. Yet, the impact is dependent on inoculants, plant provenance and soil origin. It will, therefore, be crucial to

  3. Gum arabic glycoprotein is a twisted hairy rope. A new model based on O-galactosylhydroxyproline as the polysaccharide attachment site

    Separation of the wound exudate from Acacia senegal (L.) Willd., gum arabic, on a preparative Superose-6 column gave two major fractions: a high molecular weight gum arabic glyco-protein (GAGP) containing about 90% carbohydrate and a lower molecular weight heterogeneous gum arabic polysaccharide fraction. Hydrogen fluoride-deglycosylation of GAGP gave a large hydroxyproline-rich polypeptide backbone (dGAGP). Alkaline hydrolysis of GAGP showed that most of the carbohydrate was attached to the polypeptide backbone as small hydroxyproline (Hyp)-polysaccharide substituents. The data imply a rodlike molecule with numerous small polysaccharide substituents (attached to 24% of the Hyp residues), regularly arranged along a highly periodic polypeptidemore » backbone based, hypothetically, on a 10 to 12 residue repetitive peptide motif. Thus, a simple statistical model of the gum arabic glycoprotein predicts a repeating polysaccharide substituents will maximize intramolecular hydrogen bonding if aligned along the long axis of the molecule, forming in effect a twisted hairy rope. Electron micrographs of rotary shadowed GAGP molecules support that prediction and may also explain show such apparently large molecules can exit the cell by endwise reptation through the small pores of the primary cell wall.« less

    Drylands are extensive across sub-Saharan Africa, socio-economically and ecologically important yet highly sensitive to environmental changes. Evolutionary history, as revealed by contemporary intraspecific genetic variation, can provide valuable insight into how species have responded to past environmental and population changes and guide strategies to promote resilience to future changes. The gum arabic tree (Acacia senegal) is an arid-adapted, morphologically diverse species native to the sub-Saharan drylands. We used variation in nuclear sequences (internal transcribed spacer (ITS)) and two types of chloroplast DNA (cpDNA) markers (PCR-RFLP, cpSSR) to study the phylogeography of the species with 293 individuals from 66 populations sampled across its natural range. cpDNA data showed high regional and rangewide haplotypic diversity (hT(cpSSR)=0.903–0.948) and population differentiation (GST(RFLP)=0.700–0.782) with a phylogeographic pattern that indicated extensive historical gene flow via seed dispersal. Haplotypes were not restricted to any of the four varieties, but showed significant geographic structure (GST(cpSSR)=0.392; RST=0.673; RST>RST (permuted)), with the major division separating East and Southern Africa populations from those in West and Central Africa. Phylogenetic analysis of ITS data indicated a more recent origin for the clade including West and Central African haplotypes, suggesting range expansion in this region, possibly during the Holocene humid period. In conjunction with paleobotanical evidence, our data suggest dispersal to West Africa, and across to the Arabian Peninsula and Indian subcontinent, from source populations located in the East African region during climate oscillations of the Plio-Pleistocene.

    Principal component analysis (PCA) was carried out to study the relationship between 24 meat quality measurements taken from beef round samples that were injected with curing brines containing gum arabic (1%, 1.5%, 2%, 2.5%, and 3%) and soy protein concentrate (SPC) (3.5%) at two injection levels (30% and 35%). The measurements used to describe beef round quality were expressible moisture, moisture content, cook yield, possible injection, achieved gum arabic level in beef round, and protein content, as well as descriptive sensory attributes for flavor, texture, basic tastes, feeling factors, color, and overall acceptability. Several significant correlations were found between beef round quality parameters. The highest significant negative and positive correlations were recorded between color intensity and gray color and between color intensity and brown color, respectively. The first seven principal components (PCs) were extracted explaining over 95% of the total variance. The first PC was characterized by texture attributes (hardness and denseness), feeling factors (chemical taste and chemical burn), and two physicochemical properties (expressible moisture and achieved gum arabic level). Taste attribute (saltiness), physicochemical attributes (cook yield and possible injection), and overall acceptability were useful in defining the second PC, while the third PC was characterized by metallic taste, gray color, brown color, and physicochemical attributes (moisture and protein content). The correlation loading plot showed that the distribution of the samples on the axes of the first two PCs allowed for differentiation of samples injected to 30% injection level which were placed on the upper side of the biplot from those injected to 35% which were placed on the lower side. Similarly, beef samples extended with gum arabic and those containing SPC were also visible when scores for the first and third PCs were plotted. Thus, PCA was efficient in analyzing the quality

    Inoculation of legume plants with symbiotic microorganisms is widely used to improve their development and productivity. The objective of this study was to investigate the effect of inoculation of Acacia senegal mature trees with rhizobium (Sinorhizobium) and arbuscular mycorrhizal fungus (G. mosseae, G. fasciculatum, G. intraradices) either singly or in combination, on soil properties, activity and the genetic structure of soil microbial communities. The experiment set up in Southern Senegal consisted of 4 randomized blocks of A. senegal mature trees with 4 treatments including inoculated trees with Rhizobium (R), mycorrhizal fungus (M) and with Rhizobium+mycorhizal fungus (RM) and non-inoculated control (CON). Soil were sampled 2 years after the inoculation. Soil pH, C and N and available P contents were measured. The microbial abundance and activity were measured in terms of microbial biomass C (MBC) and basal soil respiration. The community structure of the total bacterial, diazotrophic and denitrifying communities was assessed by denaturing gradient gel electrophoresis of 16S rDNA, nifH and nirK genes respectively. Inoculations with symbiont under field conditions have increased soil pH. The C and N contents were enhanced in the dual-inoculated treatments (RM). The mycorrhized treatment have displayed the lowest available P contents while RM and R treatments exhibited higher contents rates. The microbial biomass C rates were higher in treatments co-inoculated with AM fungi and Rhizobium than in those inoculated singly with AM fungi or Rhizobium strains. The basal soil respiration were positively correlated to MBC, and the highest rates were found in the co-inoculated treatments. Fingerprints of 16S rDNA gene exhibited similar patterns between inoculated treatments and the control showing that the inoculation of mature trees have not impacted the total bacterial community structure. In contrast, the inoculated treatments have displayed individually different

    Acacia gum is a hybrid polyelectrolyte containing both protein and polysaccharide subunits. We study the interfacial rheology of its adsorption layers at the oil/water interface and compare it with adsorbed layers of hydrophobically modified starch, which for economic and political reasons is often used as a substitute for Acacia gum in technological applications. Both the shear and the dilatational rheological responses of the interfaces are considered. In dilatational experiments, the viscoelastic response of the starch derivative is just slightly weaker than that for Acacia gum, whereas we found pronounced differences in shear flow: The interfaces covered with the plant gum flow like a rigid, solidlike material with large storage moduli and a linear viscoelastic regime limited to small shear deformations, above which we observe apparent yielding behavior. In contrast, the films formed by hydrophobically modified starch are predominantly viscous, and the shear moduli are only weakly dependent on the deformation. Concerning their most important technological use as emulsion stabilizers, the dynamic interfacial responses imply not only distinct interfacial dynamics but also different stabilizing mechanisms for these two biopolymers.

    Plant derived arabinogalactan proteins (AGP) were repeatedly confirmed as immunologically as well as dermatologically active compounds. However, little is currently known regarding their potential activity toward skin innate immunity. Here, we extracted and purified AGP from acacia (Acacia senegal) and baobab (Adansonia digitata) seeds to investigate their biological effects on the HaCaT keratinocyte cell line in an in vitro system. While AGP from both sources did not exhibit any cytotoxic effect, AGP from acacia seeds enhanced cell viability. Moreover, real-time quantitative reverse transcription-polymerase chain reaction (qRT-PCR) analysis showed that AGP extracted from both species induced a substantial overexpression of hBD-2, TLR-5, and IL1-α genes. These data suggest that plant AGP, already known to control plant defensive processes, could also modulate skin innate immune responses. J. Cell.

    Gum Acacia Seyal (ASY) is less valued than is gum Acacia Senegal, due to its poor emulsifying ability. The present study investigated the Maillard reaction between ASY and β-lactoglobulin (BLG) and its impact on the emulsifying properties of ASY. The reaction products of BLG/ASY mixture (r=1/4), prepared by dry-heating at 60°C and a relative humidity of 79%, as a function of incubation time, were characterized by SDS-PAGE, GPC-MALLS and DSC. The results showed that 12-24h of dry-heating under the given conditions was sufficient for conjugation, meanwhile avoiding the formation of deeply coloured and insoluble melanoidins. More than 64% of the protein was incorporated into ASY, resulting in a two-fold increase in arabinogalactan-protein (AGP) content and 3.5 times increase in weight-average molecular mass of ASY. The conjugation with BLG markedly improved the stability of ASY-stabilized emulsions and their resistance against severe conditions, such as low pH and high saline conditions.

    Background notes and statistics on Senegal are provided in the document. 196,840 sq. km. of diversified terrain are encompassed by the country, with a 1990 population of 7 million growing at the annual rate of 3%. The work force totals 3 million. Senegal claims a population comprised of 5 ethnic groups and various others, 3 religious beliefs, and speaking 5 languages. No period of education is listed as compulsory, with the country overall experiencing 28% literacy. The infant mortality rate is 78/1,000, while life expectancy is 48 years. 1989 GDP was $5 billion, and was growing at the rate of 6%. 1988 per capita GDP was $630, with a 1989 inflation rate of 2%. Agriculture accounts for 22% of GDP, industry for 24%; 1990 international trade deficit totalled $209 million. Additional data are provided on Senegal's people, government, economy, international affiliations, defense, history, political conditions, principal government officials, foreign relations, and bilateral relations with the United States. Senegal suffers from a resource-poor economy vulnerable to environmental and international commodity price fluctuations. The country depends heavily on international donor assistance. 70% of the labor force is engaged in farming, with peanuts accounting for 1/2 of agricultural output. Agroindustry investment is planned to bring Senegal further along toward food self-sufficiency. Fishing, phosphate production, and tourism are all areas for economic growth. Economic reforms along with favorable weather in recent years have resulted in real GDP growth. Foreign investment is welcomed in Senegal, as demonstrated by revised terms set forth in the investment code of 1987.

    Jatropha curcas, a Euphorbiaceae species that produces many toxicants, is increasingly planted as an agrofuel plant in Senegal. The purpose of this study was to determine whether soil priming induced by J. curcas monoculture could alter the rhizobial populations that nodulate cowpea and acacia, two locally widespread legumes. Soil samples were transferred into a greenhouse from three fields previously cultivated with Jatropha for 1, 2, and 15 years, and the two trap legumes were grown in them. Control soil samples were also taken from adjacent Jatropha-fallow plots. Both legumes tended to develop fewer but larger nodules when grown in Jatropha soils. Nearly all the nifH sequences amplified from nodule DNA were affiliated to the Bradyrhizobium genus. Only sequences from Acacia seyal nodules grown in the most recent Jatropha plantation were related to the Mesorhizobium genus, which was much a more conventional finding on A. seyal than the unexpected Bradyrhizobium genus. Apart from this particular case, only minor differences were found in the respective compositions of Jatropha soil versus control soil rhizobial populations. Lastly, the structure of these rhizobial populations was systematically imbalanced owing to the overwhelming dominance of a very small number of nifH genotypes, some of which were identical across soil types or even sites. Despite these weak and sparse effects on rhizobial diversity, future investigations should focus on the characterization of the nitrogen-fixing abilities of the predominant rhizobial strains.

    This study aimed at assessing the effect of gum arabic (Acacia senegal) oral treatment on the metabolic profile of chronic renal failure (CRF) patients. A total of 36 CRF patients (under regular haemodialysis) and 10 normal subjects participated in this study. The patients were randomly allocated into three groups-group A: 12 CRF patients under low-protein diet (LPD) (<40 g day(-1)) and gum arabic (50 g day(-1)) treatment; group B: 14 CRF patients under LPD and gum arabic, iron (ferrous sulphate, 200 mg day(-1)) and folic acid (5 mg day(-1)) treatment; group C (control group): 10 CRF patients under LPD and iron and folic acid treatment and group D: 10 normal volunteers (on normal diet) under daily dose of 50 g gum arabic. Each of the above treatments was continued for three consecutive months. Blood samples were collected from each subject before treatment and twice per month "pre-dialysis" for 3 months. Biochemical parameters measured were: serum urea, serum creatinine, serum uric acid, serum calcium and serum phosphorus. By the end of the 3 months of treatment, serum urea levels significantly decreased by 31.2 and 44.18% for group A and B, respectively, compared with the baseline (0.01 < p < 0.001) and control group (p < 0.05). Serum creatinine levels significantly decreased in the groups of gum users (A, B and D) by 9.94, 12.65 and 11.7%, respectively, compared with the control group (p < 0.001). There was a significant decrease (p < 0.05) in serum uric acid levels by 14 and 19.9% for group A and B, respectively, compared with the baseline. Serum calcium levels increased by 12.64, 15.75 and 8.75% for group A, B and D, respectively, and these increases were significantly different (0.05 < p < 0.001) from baseline and control group for groups A and B. Serum phosphorus levels significantly decreased by 22.54% for group A, 17.69% for group B and 7.71% for group D, compared with the baseline (0.05 < p < 0.001). From this study, we conclude that oral administration of

    Over 900 species of Acacia trees are found on earth, most of them produce gums. Acacia nilotica (Babul tree) is one of the major gum-yielding acacia species found in he Indian subcontinent. A. nilotica gum was collected from Maharashtra, India and characterised for its proximate analysis, physicochemical, functional, rheological and thermal properties. These properties further were compared with commercially available Acacia gum (AG). The sugar composition of the gums indicated the presence of arabinose, galactose, and rhamnose in ANG and AG. FTIR spectrums revealed the typical trend of polysaccharides for both the gums, however, the difference was observed in fingerprint region. The rheological outcomes were derived from flow curve measurements of gums at different concentrations and temperatures. Investigations of the flow curves of both gums revealed the diminutive difference in viscosity profile. The concentration difference in the monosaccharides of polysaccharides and proximate analysis of gums could be the responsible for the difference in rheological and thermal properties of gums. However, ANG shows good resemblance with AG and can be substituted for numerous applications in food and pharmaceutical industry. Copyright © 2017 Elsevier B.V. All rights reserved.

    Anecdotal evidence suggests that high fibre supplementation of dietary intake may have health benefits in renal disease related to alterations in circulating levels of short-chain fatty acids. The aim of the study was to examine the hypothesis that dietary manipulation may increase serum butyrate and thus have potential beneficial effects in renal disease. We examined the effect of dietary supplementation with a gum arabic sample of standardized molecular characteristics, Acacia(sen) SUPERGUM EM2 (SUPERGUM), on systemic levels of butyrate in normal human subjects. In an in vitro study, we also examined the potential role of butyrate in modifying the generation of the profibrotic cytokine transforming growth factor-beta (TGF-beta1) by renal epithelial cells. Following 8 weeks of dietary supplementation with 25 g/day of SUPERGUM, there was a two-fold increase in serum butyrate (n=7, P=0.03). In vitro work demonstrated that exposure of renal epithelial cells to elevated concentrations of butyrate suppressed both basal and stimulated TGF-beta1 synthesis. The action of butyrate was mediated by suppression of the extracellular signal-regulated kinase/mitogen-activated protein kinase signalling pathway. In addition, butyrate exposures reduced the response of renal epithelial cells to TGF-beta1 as assessed by luciferase activity of a TGF-beta-responsive reporter construct. Attenuation of TGF-beta1 signalling was associated with reduced phosphorylation of Smad 3 and decreased trafficking of TGF-beta1 receptors into signalling, non-lipid raft-associated membrane fractions. In conclusion, the data demonstrate that dietary supplementation with SUPERGU increased serum butyrate, which at least in vitro has beneficial effects on renal pro-fibrotic cytokine generation.

    This study examines long-term changes in Senegal's natural resources. We monitor and quantify land use and land cover changes occurring across Senegal using nearly 40 years of satellite imagery, aerial surveys, and fieldwork. We stratify Senegal into ecological regions and present land use and land cover trends for each region, followed by a national summary. Results aggregated to the national level show moderate change, with a modest decrease in savannas from 74 to 70 percent from 1965 to 2000, and an expansion of cropland from 17 to 21 percent. However, at the ecoregion scale, we observed rapid change in some and relative stability in others. One particular concern is the decline in Senegal's biodiverse forests. However, in the year 2000, Senegal's savannas, woodlands, and forests still cover more than two-thirds of the country, and the rate of agricultural expansion has slowed.

  17. Two invasive acacia species secure generalist pollinators in invaded communities

    Exotic entomophilous plants need to establish effective pollinator interactions in order to succeed after being introduced into a new community, particularly if they are obligatory outbreeders. By establishing these novel interactions in the new non-native range, invasive plants are hypothesised to drive changes in the composition and functioning of the native pollinator community, with potential impacts on the pollination biology of native co-flowering plants. We used two different sites in Portugal, each invaded by a different acacia species, to assess whether two native Australian trees, Acacia dealbata and Acacia longifolia, were able to recruit pollinators in Portugal, and whether the pollinator community visiting acacia trees differed from the pollinator communities interacting with native co-flowering plants. Our results indicate that in the invaded range of Portugal both acacia species were able to establish novel mutualistic interactions, predominantly with generalist pollinators. For each of the two studied sites, only two other co-occurring native plant species presented partially overlapping phenologies. We observed significant differences in pollinator richness and visitation rates among native and non-native plant species, although the study of β diversity indicated that only the native plant Lithodora fruticosa presented a differentiated set of pollinator species. Acacias experienced a large number of visits by numerous pollinator species, but massive acacia flowering resulted in flower visitation rates frequently lower than those of the native co-flowering species. We conclude that the establishment of mutualisms in Portugal likely contributes to the effective and profuse production of acacia seeds in Portugal. Despite the massive flowering of A. dealbata and A. longifolia, native plant species attained similar or higher visitation rates than acacias.

    Gastrointestinal nematodes are a major threat to small ruminant rearing in the Sahel area, where farmers traditionally use bioactive plants to control these worms, including Acacia nilotica and Acacia raddiana. The main aim of this study was to screen the potential anthelmintic properties of aqueous and acetone extracts of leaves of these two plants based on three in vitro assays: (1) the egg hatch inhibition assay (EHA); (2) the larvae exsheathment inhibition assay (LEIA) using Haemonchus contortus as a model; and (3) an adult mortality test (AMT) applied on Caenorhabditis elegans. For the EHA, only A. raddiana was effective with IC50 = 1.58 mg/mL for aqueous extract, and IC50 = 0.58 mg/mL for acetonic extract. For the LEIA, all extracts inhibited the exsheathment of larvae compared to the controls, and the aqueous extract of A. nilotica was more larvicidal with IC50 = 0.195 mg/mL. In general, all responses to the substances were dose-dependent and were significantly different from the control group (p < 0.05). For the AMT, the extracts of the two Acacia species were effective but A. raddiana showed greater efficacy with 100% mortality at 2.5 mg/mL and LC50 = 0.84 mg/mL (acetonic extract). The addition of polyvinyl polypyrrolidone (PVPP) to the extracts suggested that tannins were responsible for blocking egg eclosion and inducing adult mortality but were not responsible for exsheathment inhibition. These results suggest that the leaves of these Acacia species possess ovicidal and larvicidal activities in vitro against H. contortus, and adulticidal effects against C. elegans. PMID:29173278

    Between 1990 and 2001, the laboratory of Paludologie of IRD at Dakar collected over 5,500 snakes from all over Senegal. By studying this collection, an entirely new species was discovered for science and eight new species for Senegal. The presence of many specimens of rare species and the great number of localities from which snakes were collected also allowed us to solve several delicate taxonomic problems and better to specify the biogeography of Senegalese snakes. Currently, the presence in Senegal of at least 55 different species has been established with certainty. The data collected simultaneously on the burden of snakebites for public health shows considerable differences according to geographic area, with populations from south-eastern Senegal being more exposed to the risk of death by snakebite.

    Protective ant-plant mutualisms that are exploited by non-defending parasitic ants represent prominent model systems for ecology and evolutionary biology. The mutualist Pseudomyrmex ferrugineus is an obligate plant-ant and fully depends on acacias for nesting space and food. The parasite Pseudomyrmex gracilis facultatively nests on acacias and uses host-derived food rewards but also external food sources. Integrative analyses of genetic microsatellite data, cuticular hydrocarbons and behavioral assays showed that an individual acacia might be inhabited by the workers of several P. gracilis queens, whereas one P. ferrugineus colony monopolizes one or more host trees. Despite these differences in social organization, neither of the species exhibited aggressive behavior among conspecific workers sharing a tree regardless of their relatedness. This lack of aggression corresponds to the high similarity of cuticular hydrocarbon profiles among ants living on the same tree. Host sharing by unrelated colonies, or the presence of several queens in a single colony are discussed as strategies by which parasite colonies could achieve the observed social organization. We argue that in ecological terms, the non-aggressive behavior of non-sibling P. gracilis workers — regardless of the route to achieve this social structure — enables this species to efficiently occupy and exploit a host plant. By contrast, single large and long-lived colonies of the mutualist P. ferrugineus monopolize individual host plants and defend them aggressively against invaders from other trees. Our findings highlight the necessity for using several methods in combination to fully understand how differing life history strategies affect social organization in ants. PMID:22662191

    Halophytes develop various morphological and physiological traits that enable them to grow successfully on saline substrates. Parasitic plants on halophytic hosts may also encounter salt stress. We investigated the mistletoe Plicosepalus acaciae (syn: Loranthus acacia; Loranthaceae), which occurs on 5 halophytic and at least 10 non-halophytic hosts in the Southern Arava Valley (Israel). Plicosepalus acaciae is a common parasite north of Eilat to the Dead Sea area and in the Jordan Valley. Morphological and physiological responses of P. acaciae to salinity were investigated by comparison of plants on halophytic with those on non-halophytic hosts. Ion patterns of different host–parasite associations were determined as was the development of leaf succulence at different growth stages. The leaf water content of P. acaciae increased and leaves developed succulence when growing on halophytic hosts, especially on Tamarix species, where leaf water content was three times higher than that on non-halophytic hosts and the leaf volume increased four to five times. The reason for increased succulence was a higher ion concentration of, and osmotic adjustment with, Na+ and Cl−. Plicosepalus acaciae showed a high morphological and ecophysiological plasticity, enabling it to cope with salt stress, and can be classified as a facultative eu-halophyte, which increases its halo-succulence according to the host. Host–parasite associations are a model system for the investigation of halophytes under different salt stress conditions. PMID:25515726

    The systematics of Mimosoideae has been in a state of flux, which reflects overall poor knowledge of the evolution and biogeography of this group. Preliminary molecular phylogenetic analyses suggest the tribal system of Mimosoideae needs a complete revision. This has led to the use of new generic names for Acacia sensu lato (s.l. hereafter) following the re-typification of Acacia with an Australian type: (i) Acacia sensu stricto (s.s. hereafter), Vachellia, Senegalia, Acaciella and Mariosousa. This study reconstructs the evolutionary history of Mimosoideae, using the most comprehensive sampling to date, with an emphasis on African species. It aims to reconstruct the phylogenetic relationships among the five recognized genera within Acacieae as the precursor to elucidate the paleo-biogeography of mimosoids and their adaptation to open habitats in the Cenozoic. The basal position of Mimoseae lineages with regards to Vachellia and Senegalia+Mariosousa+Acaciella+Ingeae+Acacia s.s. clades is a novel finding. Vachellia (formerly Acacia subgenus Acacia) is found monophyletic. A grade including the remaining Mimoseae lineages is found sister to the Senegalia+Mariosousa+Acaciella+Ingeae+Acacia s.s. clade. The major clades originated in the late Oligocene-early Miocene (∼25mya). The transitions from close to open habitats occurred during the Miocene for at least four mimosoid lineages. These are interpreted as responses to increased seasonality leading to fire climates and drying trends in the Miocene, which allowed the expansion of open habitats, such as savannas, worldwide.

The crushing and impact strengths of both the acacia and eucalyptus wood chars (made by slow carbonization) decreased with increase of preparation temperature up to 600 C, followed by an increase thereafter. These wood chars showed a continuous increase in shatter index values with carbonization temperature. In contrast to slow carbonization (heating rate 4 C min{sup {minus}1}), rapid carbonization (heating rate 30 C min{sup {minus}1})more » yielded chars of lower crushing strengths. Slowly carbonized eucalyptus wood gave chars of superior crushing and impact strengths than those produced from acacia wood under the same carbonization conditions. The crushing and impact strengths of these wood chars, in general, have shown an increase with increase in their apparent density. The crushing strength of cubic-shaped wood char decreased with increase in size.« less

    Anthropogenic habitat modification often has a profound negative impact on the flora and fauna of an ecosystem. In parts of the Middle East, ephemeral rivers (wadis) are characterised by stands of acacia trees. Green, flourishing assemblages of these trees are in decline in several countries, most likely due to human-induced water stress and habitat changes. We examined the importance of healthy acacia stands for bats and their arthropod prey in comparison to other natural and artificial habitats available in the Arava desert of Israel. We assessed bat activity and species richness through acoustic monitoring for entire nights and concurrently collected arthropods using light and pit traps. Dense green stands of acacia trees were the most important natural desert habitat for insectivorous bats. Irrigated gardens and parks in villages and fields of date palms had high arthropod levels but only village sites rivalled acacia trees in bat activity level. We confirmed up to 13 bat species around a single patch of acacia trees; one of the richest sites in any natural desert habitat in Israel. Some bat species utilised artificial sites; others were found almost exclusively in natural habitats. Two rare species (Barbastella leucomelas and Nycteris thebaica) were identified solely around acacia trees. We provide strong evidence that acacia trees are of unique importance to the community of insectivorous desert-dwelling bats, and that the health of the trees is crucial to their value as a foraging resource. Consequently, conservation efforts for acacia habitats, and in particular for the green more densely packed stands of trees, need to increase to protect this vital habitat for an entire community of protected bats.

    The composition and physicochemical properties of defatted acacia flour (DFAF), acacia protein concentrate (APC) and acacia protein isolate (API) were evaluated. The results indicated that API had lower, ash and fat content, than DFAF and APC. Also, significant difference in protein content was noticed among DFAF, APC and API (37.5, 63.7 and 91.8%, respectively). Acacia protein concentrate and isolates were good sources of essential amino acids except cystine and methionine. The physicochemical and functional properties of acacia protein improved with the processing of acacia into protein concentrate and protein isolate. The results of scanning electron micrographs showed that DFAF had a compact structure; protein concentrate were, flaky, and porous type, and protein isolate had intact flakes morphology.

  15. Nitrogen uptake by Eucalyptus regnans and Acacia spp. - preferences, resource overlap and energetic costs.

    In southeastern Australia, the overstory species Eucalyptus regnans F. Muell. commonly grows with either of the two leguminous understory trees, Acacia melanoxylon (R. Br. Ex Ait. f.) or Acacia dealbata (Link.). Our objective was to elucidate interactions between the dominant eucalypt and its companion acacias for nitrogen (N) sources. Use of stable N isotopes as tracers revealed that ammonium was the preferred soil N source for all species, nevertheless, total N uptake varied greatly among species. Studies with double-labeled ((13)C/(15)N) glutamine indicated the uptake of this form of organic N in small amounts by both E. regnans and the Acacia spp. These and other data imply that, in contrast to boreal forests, organic N is not a significant component of N nutrition in mountain ash forests. Field and laboratory studies provided evidence that N(2)-fixation capacity of acacias varies with stand development, with N-fixing species playing an important role in N nutrition during the early but not the mature stages of forest growth. An index of N-uptake efficiency - the amount of oxygen consumed per unit N taken up - was compared across four N sources and three species. Nitrate uptake was the least efficient form of N acquisition, especially compared with ammonium uptake which was up to 30-fold less costly. Efficiency of glutamine uptake was intermediate between that of ammonium and nitrate. Differences in uptake efficiency among N forms were most pronounced for the Acacia spp. and least for E. regnans. We conclude that an overlap in requirements among sympatric Acacia spp. and E. regnans for specific soil N sources can be bypassed because of changes in biochemical strategies of Acacia spp. triggered by increasing soil N concentrations during stand development. Further studies might elucidate whether this is a common feature of complex forest ecosystems, or a specialty of the interaction between eucalypts and acacias.

    Environmental degradation resulting from long-term drought and land use change has affected terrestrial carbon (C) stocks within Africa's Sahel. We estimated Senegal's terrestrial carbon stocks in 1965, 1985, and 2000 using an inventory procedure involving satellite images revealing historical land use change, and recent field measurements of standing carbon stocks occurring in soil and plants. Senegal was divided into eight ecological zones containing 11 land uses. In 2000, savannas, cultivated lands, forests, and steppes were the four largest land uses in Senegal, occupying 70, 22, 2.7, and 2.3 percent of Senegal's 199,823 km2. System C stocks ranged from 9 t C ha−1 in degraded savannas in the north, to 113 t C ha−1 in the remnant forests of the Senegal River Valley. This approach resulted in estimated total C stocks of 1019 and 727 MT C between 1965 and 2000, respectively, indicating a loss of 292 MT C over 35 years. The proportion of C residing in biomass decreased with time, from 55 percent in 1965 to 38 percent in 2000. Calculated terrestrial C flux for 1993 was −7.5 MT C year−1 and had declined by 17 percent over the previous 18 years. Most of the terrestrial C flux in 1993 was attributed to biomass C reduction. Human disturbance accounted for only 22 percent of biomass C loss in 1993, suggesting that the effects of long-term Sahelian drought continue to play an overriding role in ecosystem change. Some carbon mitigation strategies for Senegal were investigated, including potential C sequestration levels. Opportunities for C mitigation exist but are constrained by available knowledge and access to resources.

    The feasibility of commercial-scale co-composting of waste biomass from the control of invasive Acacia species with pine bark waste from the lumber industry, in a blend ratio of 60:40 (v:v), was investigated and compared with previous research on the composting of Acacia without additional feedstock, to determine the potential process and end-product quality benefits of co-composting with bark. Pile temperatures rose rapidly to >70 °C and were maintained at >60 °C for several months. Acacia and bark biomass contained a large fraction of mineralizable organic matter (OM) equivalent to approximately 600 g kg(-1) of initial OM. Bark was more recalcitrant to biodegradation compared with Acacia, which degraded at twice the rate of bark. Therefore, incorporating the bark increased the final amount of compost produced compared with composting Acacia residues without bark. The relatively high C/N ratio of the composting matrix (C/N=56) and NH3 volatilization explained the limited increases in NH4+-N content, whereas concentrations of conservative nutrient elements (e.g. P, K, Ca, Mg, Fe) increased in proportion to OM mineralization, enriching the compost as a nutrient source for horticultural use. Nitrogen concentrations also increased to a small extent, but were much more dynamic and losses, probably associated with N volatilization mechanisms, were difficult to actively control. The physicochemical characteristics of the stabilized end-product, such as pH, electrical conductivity and OM content, were improved with the addition of bark to Acacia biomass, and the final compost characteristics were suitable for use for soil improvement and also as horticultural substrate components.

    Nowadays,most of the pathogenic bacteria become resistant to antibiotics. Therefore,the pharmaceutical properties of the natural plant extracts have become of interest to researchers as alternative antimicrobial agents. In this study,antibacterial activities of extract gained from Acacia etbaica, Acacia laeta, Acacia origena and Acacia pycnantha have been evaluated against isolated pathogenic bacteria (Strains MFM-01, MFM-10 and AH-09) using agar well diffusion methods.The bacterial strains were isolated from infected individuals,and their exact identification was detected on the basis of 16S rRNA gene amplification and sequence determination. Alignment results and the comparison of 16 SrRN A gene sequences of the isolates to 16 SrRN A gene sequences available in Gen Bank data base as well as the phylogenetic analysis confirmed the accurate position of the isolates as Klebsiella oxytoca strain MFM-01, Staphylococcus aureus strain MFM-10 and Klebsiella pneumoniae strain AH-09. Except for cold water, all tested solvents (Chloroform, petroleum ether, methanol, diethyl ether, and acetone) showed variation in their activity against studied bacteria. GC-MS analysis of ethanol extracts showed that four investigated Acacia species have different phyto components. Eight important pharmaceutical components were found in the legume of Acacia etbaica, seven in the legume of Acacia laeta, fifteen in the legume of Acacia origena and nine in the leaves of Acacia pycnantha. A dendrogram was constructed based on chemical composition, revealed that Acacia laeta is more closely related to Acacia etbaica forming on eclade, whereas Acacia origena less similar to other species. Our results demonstrated that, investigated plants and chemical compounds present could be used as promising antibacterial agents.

    Fuel pellet is one of the innovation products that can be produced from various sources of biomass such as agricultural residues, forestry and also wood industries including wood bark. Herein this paper, the potential fuel pellet production using Acacia mangium bark that abundant wasted from chip mill industry was studied. Fuel pellet was produced using a modified animal feed pellet press machine equipped with rotating roller-cylinders. The international standards quality of fuel pellet such as ONORM (Austria), SS (Sweden), DIN (Germany), EN (European) and ITEBE (Italy) were used to evaluate the optimum composition of feedstock and additive used. Theresults showed the quality offuel pellet produced were good compared to commercial sawdust pellet. Mixed of Acacia bark (dust) with 10% of tapioca and 20% of glycerol (w/w) was increased the stable form of pellet and the highest heating value to reached 4,383 Kcal/kg (calorific value). Blending of Acacia bark with tapioca and glycerol was positively improved its physical, chemical and combustion properties to met the international standards requirement for export market. Based on this finding, production of fuel pellet from Acacia bark waste biomass was promising to be developed as an alternative substitution of fossil energy in the future.

  3. Energy and environment: A political ecology of woodfuels in Senegal

    NASA Astrophysics Data System (ADS)

    Pires, E. Mark

    This study examines relationships between energy use and the exploitation of woodland natural resources in the West African nation of Senegal. As in many other countries in the developing world, the majority of the population in Senegal depend on woodfuels, i.e., firewood and charcoal, to satisfy most of their household energy needs. Consequences of this situation include added pressure on the country's limited natural resource base, and increased socioeconomic hardship, particularly for women, as woodfuel resources become increasingly scarce. Woodfuel energy problems in developing countries are typically described in terms of an imbalance between supply and demand that is driven by rapid population growth. However, recent research suggests that a number of other factors should be explored in order to achieve a more thorough understanding of the relationship between woodfuel energy and forest resource management. This study attempts to determine what some of these factors are, and to explain how they inform the energy-environment situation in the case of Senegal. In addition, I examine the scope for addressing Senegal's woodfuel problem through greater local community participation in managing energy and natural resources, a current thrust in many international initiatives designed to help the country cope with this persistent problem. A relatively new conceptual framework for the analysis of human-environment relationships---viz. political ecology---is employed in this study. I attempt to show how political ecology can contribute to the resolution of Senegal's energy-environment dilemma by considering a more inclusive suite of social, economic, political, and environmental variables than has been explored by previous approaches. Findings from the research demonstrate the ability of the political ecology approach to capture many heretofore unexplored factors related to the energy-environment nexus in Senegal. A detailed matrix is generated that illustrates the

    The profession of midwifery continues to hold a prominent place in the health manpower structure of many developing countries. The training program at the School of Midwifery in Senegal lasts for 3 years and is based on the teaching in French midwifery schools. Because of the special conditions in Senegal, the objective of the teaching is to train midwives to be multiskilled workers who can deliver health care services in preventive as well as in curative medicine, in both rural and urban settings, and in the maternity clinic as well as in the community. The following proposals for revising the training were developed: 1) the level of admission will become the baccalaureate; 2) the nursing training will be strengthened and the length of rural field practice will be extended to at least 3 months, including provisions for practical application of primary health care; 3) in pediatrics, more stress will be placed on diet counseling, home visits, and the treatment of infectious and parasitic diseases; 4) training will cover administration, supervision, evaluation, and maintenance of materials and facilities. The midwife in Senegal also plays a primary role in family planning, and in family planning centers should be reponsible for gynecological examinations; giving assistance in the choice of contraceptive methods; placement, follow-up, and removal of IUDs; and detection of sterility, genital and mammary cancers, and sexually transmissible diseases.

    Assessment of water availability and demand in Lake Guiers, SenegalWater resources are critical to economic growth and social development. In most African countries, supply of drinking water to satisfy population needs is a key issue because of population growth and climate and land use change. During the last three decades, increasing population, changing patterns of water demand, and concentration of population and economic activities in urban areas has pressurize Senegal's freshwater resources. To overcome this deficit, Senegal turned, to the exploitation of the Lake Guiers. It is the sole water reservoir which can be used extensively as a stable freshwater. Its water is use for irrigating crops and sugar refinery and as a drinking water resource for urban centres, including Dakar, the capital city of Senegal, as well as for the local population and animal herds. To ensure sustainability, a greater understanding of Lake Guiers's water resources and effective management of its use will be required. In this study we developed and quantified future water situation (water availability and demand) in Lake Guiers under scenarios of climate change and population growth until 2050, using the water management model WEAP (Water Evaluation And Planning system). The results show that the pressure on Lake Guiers's water resources will increase, leading to greater competition between agriculture and municipal demand site. Decreasing inflows due to climate change will aggravate this situation. WEAP results offer basis to assister lake Guiers water resources manager for an efficient long-term planning and management.

    Virginity is part of our existence in the world as embodied sexual subjects. While many meanings are associated with virginity, in most of the Arab world virginity relates to the presence of a hymen and extends to encompass the honor of the Arab community, and virginity loss commonly relate to first vaginal intercourse. This study explored the meanings of virginity from the perspectives of Arab and Arab American women. A qualitative phenomenological approach, informed by the philosophy of Maurice Merleau-Ponty, was used to conduct in-depth interviews with ten women. We identified one over-arching theme Virginity as Identity , and two major themes Embodiment of Virginity and "We are Arabs." To reach an embodied virginity, participants went through a disembodied virginity process, reflecting society's perceptions and values of virginity related to anatomical presence of a hymen and society's honor. "We are Arabs" describes the ways women identified with the Arab ethnic identity as a shared overall identification, but differed from one lived experience to another, and influenced how participants embodied virginity. Our participants provided a better understanding of the diverse meanings of virginity that move beyond the binary of virginity and virginity loss, and into a spectrum of embodied meanings. Findings suggest the need for future research around sexuality in Arab Americans with attention to socio-political contexts in order to understand the nature and context of sexual initiation and its impact on sexual behaviors and well-being.

    Acacia gum solution was employed as a carrier for electrospray-assisted drying of probiotic cells. To optimize the process, effect of gum concentration, thermal sterilization as a prerequisite for microbial studies, and surfactant addition on physical properties of feed solution was investigated. Increasing gum concentration from 20 to 40 wt.% led to a viscosity increase, whilst surface tension did not change meaningfully and electrical conductivity declined after an increasing trend up to 30 wt.% of the gum. Thermal sterilization increased the viscosity without any significant effect on the conductivity and surface tension. Surfactant addition reduced the surface tension and conductivity but the viscosity increased. Highly uniform particles were formed by electrospray-assisted drying of autoclaved 35 wt.% acacia gum solution containing 1 wt.% Tween 80. Thermal sterilization and surfactant addition improved electrospray-ability of acacia gum solution. Bacterial count showed that more than 96 percent of probiotic cells passed the process viably.

  11. Risk analysis. HIV / AIDS country profile: Senegal.

    PubMed

    1996-12-01

    Since the first acquired immunodeficiency syndrome (AIDS) case was confirmed in 1986, Senegal has conducted an aggressive prevention campaign. Senegal's National AIDS Committee has noted the contributions of poverty and migration to the spread of AIDS. By June 1994, 1297 AIDS cases had been reported and an estimated 500,000 people (1.4% of the population) were infected with human immunodeficiency virus (HIV)-1 and 2. The highest rate of HIV infection (14%) exists among commercial sex workers. At present, HIV/AIDS cases are concentrated in Dakar, Kaolack, the Matam region, and Ziguinchor; however, the growing importance of inter-regional trading is expected to spread HIV to the smaller towns and rural areas. Also salient is the recent devaluation by 50% of the CFA franc, which has reduced the public sector workforce and led many poor urban residents into commercial sex work. CFA devaluation has made Senegal attractive to tourists and business visitors--another factor responsible for growth of the legalized commercial sex industry. Although sex workers are instructed in condom use and tested annually for HIV, only 850 of the 2000 registered sex workers have reported for check-ups, and the majority of prostitutes are unregistered. Senegal's AIDS Plan for 1994-98 focuses on care of AIDS patients, pressures placed on family structures by HIV, and AIDS-related erosions in the status of women. Each health service region has its own local plan for AIDS/HIV and sexually transmitted diseases, supervised by a regional committee. Public education has involved outreach to religious leaders, promotion of affordable condoms, and distribution of over 75,000 leaflets to key target populations. About US $16 million of the $25,688,875-budget HIV/AIDS program for 1994-98 was pledged by external donors.

    The performance of several hydrocolloids (3 gum acacias, 1 modified gum acacia, and 3 modified starches) in stabilizing beverage emulsions and corresponding model beverages was investigated employing different core materials, emulsifier usage levels, and storage temperatures. Concentrated emulsions were prepared using orange terpenes or Miglyol 812 (comprising medium-chain triglycerides, MCT) weighted 1:1 with ester gum, stored at 25 or 35 degrees C, and analyzed on days 0, 1, and 3. On day 3, model beverages were made from each emulsion, stored at both temperatures, and analyzed weekly for 4 wk. Stability of concentrated emulsions was assessed by measuring mean particle size and by visual observations of ringing; beverage stability was judged similarly and also by loss of turbidity. Particle size measurements showed concentrated emulsions containing gum acacia or modified gum acacia with either core material were stable over 3 d storage at both temperatures whereas those made with modified starches were not, destabilization being faster at 35 degrees C. Beverages based on orange terpenes, in contrast to Miglyol, yielded smaller mean particle sizes, both on manufacture and during storage, regardless of hydrocolloid used. Visual observations of ringing generally supported this finding. Modified gum acacia was evaluated at both recommended and higher usage levels, stability increasing in the latter case. In general, all gum acacia and modified gum acacia emulsifiers were superior in stability to those based on modified starches, at either temperature, for orange terpene-based beverages. In Miglyol-based beverages, similar results were seen, except 1 modified starch performed as well as the gum acacia products.

    Toxoplasma gondii is an obligate, intracellular, parasitic protozoan within the phylum Apicomplexa that causes toxoplasmosis in mammalian hosts (including humans) and birds. We used modified direct agglutination test for the screening of the animals' sera collected in Senegal. In total, 419 animals' sera have been studied: 103 bovines, 43 sheep, 52 goats, 63 horses, 13 donkeys and 145 dogs. The collection of sera was performed in four different regions of Senegal: Dakar, Sine Saloum, Kedougou and Basse Casamance from 2011 to 2013. We have revealed antibodies in 13% of bovines, 16% of sheep, 15% of goats, 30% of horses, 23% of donkeys and 67% of dogs. Private dogs from villages were more often to have the anti-Toxoplasma antibodies compared to security society-owned dogs from Dakar. It may be explained by different meal consumed by dogs (factory-produced meal for dogs from Dakar vs. irregular sources for village dogs). Intense circulation of T. gondii in the studied zone may explain the unusually high seroprevalence among horses and donkeys. Tropical climate with high temperature and humidity is favorable for the conservation of oocysts of T. gondii. Results presented here may contribute to the evaluation of the risks of toxoplasmosis in humans in Senegal.

    2013-09-09

    Repeated colonisation of novel host-plants is believed to be an essential component of the evolutionary success of phytophagous insects. The relative timing between the origin of an insect lineage and the plant clade they eat or reproduce on is important for understanding how host-range expansion can lead to resource specialisation and speciation. Path and stepping-stone sampling are used in a Bayesian approach to test divergence timing between the origin of Acacia and colonisation by thrips. The evolution of host-plant conservatism and ecological specialisation is discussed. Results indicated very strong support for a model describing the origin of the common ancestor of Acacia thrips subsequent to that of Acacia. A current estimate puts the origin of Acacia at approximately 6 million years before the common ancestor of Acacia thrips, and 15 million years before the origin of a gall-inducing clade. The evolution of host conservatism and resource specialisation resulted in a phylogenetically under-dispersed pattern of host-use by several thrips lineages. Thrips colonised a diversity of Acacia species over a protracted period as Australia experienced aridification. Host conservatism evolved on phenotypically and environmentally suitable host lineages. Ecological specialisation resulted from habitat selection and selection on thrips behavior that promoted primary and secondary host associations. These findings suggest that delayed and repeated colonisation is characterised by cycles of oligo- or poly-phagy. This results in a cumulation of lineages that each evolve host conservatism on different and potentially transient host-related traits, and facilitates both ecological and resource specialisation.

The Senegal facility was conceived for scientific capacity building and equally to act as a focal point aimed at using the local scientific expertise. An anticipated outcome would be a contribution to the reduction of an ever-growing brain drain process suffered by the country, and the African continent in general. The development of the project led also to a strong African orientation of the facility: built for international collaboration, it is to be a pan-African endeavor and to serve primarily African countries. The facility received a presidential approval in a 2003 meeting and will develop an interdisciplinary program centered on a strong materials science research which will also allow for the establishment of an advanced analytical (physical chemistry) laboratory. A central part of the facility will be linked to state-of-the art accelerator mass spectrometry, cyclotron and low energy electromagnetic accelerator systems. )

    High severity wildfires pose threats to human assets, but are also perceived to impact vegetation communities because a small number of species may become dominant immediately after fire. However there are considerable gaps in our knowledge about species-specific responses of plants to different fire severities, and how this influences fuel hazard in the short and long-term. Here we conduct a floristic survey at sites before and two years after a wildfire of unprecedented size and severity in the Warrumbungle National Park (Australia) to explore relationships between post-fire growth of a fire responsive shrub genera (Acacia), total mid-story vegetation cover, fire severity and fuel hazard. We then survey 129 plots surrounding the park to assess relationships between mid-story vegetation cover and time-since-fire. Acacia species richness and cover were 2.3 and 4.3 times greater at plots after than before the fire. However the same common dominant species were present throughout the study. Mid-story vegetation cover was 1.5 times greater after than before the wildfire, and Acacia species contribution to mid-story cover increased from 10 to 40%. Acacia species richness was not affected by fire severity, however strong positive associations were observed between Acacia and total mid-story vegetation cover and severity. Our analysis of mid-story vegetation recovery showed that cover was similarly high between 2 and 30years post-fire, then decreased until 52years. Collectively, our results suggest that Acacia species are extremely resilient to high severity wildfire and drive short to mid-term increases in fuel hazard. Our results are discussed in relation to fire regime management from the twin perspectives of conserving biodiversity and mitigating human losses due to wildfire. Copyright © 2016 Elsevier B.V.

    Seed of Australian acacia species, Acacia colei, Acacia elecantha, Acacia torulosa, Acacia turmida and Acacia saligna, were analysed for the presence of toxic non-protein amino acids and the levels of essential amino acids. Amines were derivatised with 6-aminoquinolyl-N-hydroxysuccinimidyl carbamate before analysis using liquid chromatography electrospray ionisation triple quadrupole mass spectrometry (LC-ESI-QQQ-MS). Multiple reaction monitoring (MRM) with optimised transitions and collision energies for each analyte were employed. The known nephrotoxic compound djenkolic acid was found to be present at elevated levels in all species tested. The lowest levels were in A. colei (0.49% w/w) and the highest in A. saligna (1.85% w/w). Observed levels of djenkolic acid are comparable to measured and reported levels found in the djenkol bean. Subsequent testing of seed processing methods showed djenkolic acid levels can be significantly reduced by over 90% by dry roasting at 180 °C rendering the seed safe for human consumption.

    Introducing nitrogen-fixing bacteria as an inoculum in association with legume crops is a common practice in agriculture. However, the question of the evolution of these introduced microorganisms remains crucial, both in terms of microbial ecology and agronomy. We explored this question by analyzing the genetic and symbiotic evolution of two Bradyrhizobium strains inoculated on Acacia mangium in Malaysia and Senegal 15 and 5 years, respectively, after their introduction. Based on typing of several loci, we showed that these two strains, although closely related and originally sampled in Australia, evolved differently. One strain was recovered in soil with the same five loci as the original isolate, whereas the symbiotic cluster of the other strain was detected with no trace of the three housekeeping genes of the original inoculum. Moreover, the nitrogen fixation efficiency was variable among these isolates (either recombinant or not), with significantly high, low, or similar efficiencies compared to the two original strains and no significant difference between recombinant and nonrecombinant isolates. These data suggested that 15 years after their introduction, nitrogen-fixing bacteria remain in the soil but that closely related inoculant strains may not evolve in the same way, either genetically or symbiotically. In a context of increasing agronomical use of microbial inoculants (for biological control, nitrogen fixation, or plant growth promotion), this result feeds the debate on the consequences associated with such practices.

    Background: Helicobacter pylori (H. pylori) is linked to the development of the majority of peptic ulcers and some types of gastric cancers, and its antibiotic resistance is currently found worldwide. Objective: This study is aimed at evaluating the anti-H. pylori activity of Korean acacia honey and isolating the related active components using organic solvents. Material and Methods: The crude acacia honey was extracted with n-hexane, dichloromethane, ethyl acetate (EtOAc), and n-butanol. The EtOAc extract was subjected to octadecyl-silica chromatography. The extracts and fractions were then examined for anti-H. pylori activity using the agar well diffusion method. The antimicrobial activity of abscisic acid against H. pylori was investigated by determining the minimum inhibitory concentrations (MICs), minimum bactericidal concentrations (MBCs), and by performing a time-kill assay. Results: Abscisic acid related to the botanical origins of acacia honey from Korea has been analyzed using ultra-performance liquid chromatography. The MICs and MBCs of abscisic acid were 2.7 ± 1.3 and 6.9 ± 1.9 μg/mL, respectively. The bactericidal activity of abscisic acid (at 10.8 μg/mL corresponding to 4 × MIC) killed the organism within 36–72 h. These results suggest that abscisic acid isolated from Korean acacia honey has antibacterial activity against H. pylori. Conclusion: Abscisic acid isolated from Korean acacia honey can be therapeutic and may be further exploited as a potential lead candidate for the development of treatments for H. pylori-induced infections. SUMMARY The crude acacia honey was extracted with n-hexane, dichloromethane, EtOAc, and n-butanolThe EtOAc extract yielded eight fractions and four subfractions were subsequently obtained chromatographicallyAbscisic acid was isolated from one subfractionAll the solvent extracts and fractions showed antibacterial activity against H. pyloriAbscisic acid exhibited antibacterial activity against H. pylori

    The establishment of a Shi`i Islamic network in Senegal is one alternative to following the country's dominant Sufi orders. I examine Senegalese conversion narratives and the central role played by the Iranian Revolution, contextualizing life stories (trans)nationally in Senegal's political economy and global networks with Iran and Lebanon. Converts localize foreign religious ideologies into a ‘national’ Islam through the discourse that Shi`i education can bring peace and economic development to Senegal. Senegalese Shi`a perceive that proselytizing, media technologies, and Muslim networking can lead to social, cultural and perhaps even political change through translating the Iranian Revolution into a non-violent reform movement.

    The objectives in preparing this volume are threefold. First, at a time when misconceptions about the impact of Arab oil are current in the West, objective and reasoned judgments about the implications of growing Arab oil wealth are sought. To judge by accounts in the news media and the popular stereotypes to which they seem to lead, many believe the world economic and political system is seriously threatened by the Arabs. Some also apparently believe that the Arab world itself is being altered beyond recognition . . . . Taken as a group, the chapters in this volume lay tomore » rest such popular misconceptions and place in their proper perspective the changes being brought about by Arab oil wealth. Second, this volume is intended to fill a gap in the small but growing body of scholarly literature on Arab oil. A number of excellent studies have appeared in recent years, but most have been written from the perspective of a single discipline and/or ideology. Further, the majority of these works focus on the international consequences of Arab oil and neglect forces operating within the Arab oil-producing countries themselves . . . . In preparing this volume, an objective was to bring together a wide variety of viewpoints in order to present a comprehensive and balanced examination of the impact of Arab oil. Third, the volume is an assemblage of 16 papers for the specialist and the nonspecialist reader. It attempts to serve as a ready reference on the topic of Arab oil.« less

  12. Senegal: where "card-carrying" sex workers are legal.

    PubMed

    1995-06-01

    An estimated 1.5% of Senegal's 5 million adult population is HIV-seropositive, with 3000 people having already died of AIDS-related illnesses. Although 75% of those with AIDS are men, women comprise the majority of people infected with HIV. This latter phenomenon is most likely the result of men having become infected before women because of the former's greater degree of travel relative to women. Infection with HIV-2 accounts for 70% of those with HIV, but for only 30% of AIDS cases. HIV-1 is, however, becoming a growing problem since it seems to be transmitted more easily and develop into AIDS more quickly. 15% of prostitutes in Senegal are HIV-seropositive compared to more than 50% of comparable subgroups in most African countries. Experts cannot say for sure why Senegal has a comparatively low rate of HIV, but several factors have been posited as explanations. The comparatively low rate of infection could be related to the long distance between Senegal and the HIV-1 epicenters of east and central Africa, the ability of HIV-2 infection to help the body fight off HIV-1, the strong Islamic influence which has made male circumcision universal thus reducing the risk of contracting HIV, the provision of AIDS awareness and prevention early in the epidemic, and the government's permissive approach to commercial sex. This latter factor is probably the most important related to the current status of HIV/AIDS in Senegal. It has been legal since 1966 to sell sex as long as the sex worker is registered, over 21 years old, has a regular medical check-up, and can present an up-to-date medical report card to the police upon request. This approach was established by then-president Senghor to reduce the incidence and prevalence of sexually transmitted diseases (STD). Registered sex workers since 1986 have been tested for HIV, advised on how to avoid infection, and given free condoms. In anonymous questionnaires, 70-75% of all Dakar's official sex workers reported always using

    Background In Senegal, with the variable routine vaccination coverage, the risk for illness and death from measles still exists as evidenced by the measles epidemic episode in 2009. Since 2002 a laboratory-based surveillance system of measles was established by the Ministry of Health and the Institut Pasteur de Dakar. The present study analysed the data collected over the 10 years inclusive between 2004-2013 in order to define a measles epidemiological profile in Senegal, and we carried out a phylogenetic analysis of measles virus circulating in Senegal over the period 2009-2012. Methodology and Results A total number of 4580 samples were collected from suspected cases, with the most cases between 2008 and 2010 (2219/4580; 48.4%). The majority of suspected cases are found in children from 4-6 years old (29%). 981 (21.4%) were measles laboratory-confirmed by IgM ELISA. The measles confirmation rate per year is very high during 2009-2010 periods (48.5% for each year). Regarding age groups, the highest measles IgM-positivity rate occurred among persons aged over 15 years with 39.4% (115/292) followed by 2-3 years old age group with 30.4% (323/1062) and 30% (148/494) in children under one year old group. The majority of suspected cases were collected between February and June and paradoxically confirmed cases rates increased from July (77/270; 28.6%) and reached a peak in November with 60% (93/155). Phylogenetic analysis showed that all the 29 sequences from strains that circulated in Senegal between 2009 and 2012 belong to the B3 genotype and they are clustered in B3.1 (2011-2012) and B3.3 (2009-2011) sub-genotypes according to a temporal parameter. Conclusion Improvements in the measles surveillance in Senegal are required and the introduction of oral fluid and FTA cards as an alternative to transportation of sera should be investigated to improve surveillance.

    Undiscovered, conventional oil and gas resources were assessed in the Senegal Province as part of the U.S. Geological Survey World Petroleum Assessment 2000 (U.S. Geological Survey World Energy Assessment Team, 2000). Although several total petroleum systems may exist in the province, only one composite total petroleum system, the Cretaceous-Tertiary Composite Total Petroleum System, was defined with one assessment unit, the Coastal Plain and Offshore Assessment Unit, having sufficient data to allow quantitative assessment. The primary source rocks for the Cretaceous-Tertiary Composite Total Petroleum System are the Cenomanian-Turonian marine shales. The Turonian shales can be as much as 150 meters thick and contain Type II organic carbon ranging from 3 to 10 weight percent. In the Senegal Province, source rocks are mature even when situated at depths relatively shallow for continental passive margin basins. Reservoir rocks consist of Upper Cretaceous sandstones and lower Tertiary clastic and carbonate rocks. The Lower Cretaceous platform carbonate rocks (sealed by Cenomanian shales) have porosities ranging from 10 to 23 percent. Oligocene carbonate rock reservoirs exist, such as the Dome Flore field, which contains as much as 1 billion barrels of heavy oil (10? API, 1.6 percent sulfur) in place. The traps are a combination of structural closures and stratigraphic pinch-outs. Hydrocarbon production in the Senegal Province to date has been limited to several small oil and gas fields around Cape Verde (also known as the Dakar Peninsula) from Upper Cretaceous sandstone reservoirs bounded by normal faults, of which three fields (two gas and one oil) exceed the minimum size assessed in this study (1 MMBO; 6 BCFG). Discovered known oil resources in the Senegal Province are 10 MMBO, with known gas resources of 49 BCFG (Petroconsultants, 1996). This study estimates that 10 percent of the total number of potential oil and gas fields (both discovered and undiscovered) of at

    In Sub-Saharan Africa, 90 % of wetlands provide ecosystem services to societies, especially for agriculture and fishing. However, tropical rivers are increasingly regulated to provide hydroelectricity and irrigated agriculture. Modifications of flows create new hydrological conditions that affect floodplains ecology and peoples' livelihoods. In the Senegal river valley, large dams were built during the 1980's to secure water resources after a decade of water scarcity in the 1970's: Manantali in the upper basin with a reservoir of 12km3 and Diama close to estuary to avoid saltwater intrusion during dry season. Senegal river water resources are known under the supervision of Senegal River Basin Development Organization (OMVS), which defines water allocation between different goals (electricity, irrigation, traditional activities). This study, based on the concept of socio-hydrology, analyses socio-ecological changes following thirty years of dam management. The work enlightens adaptation mechanisms of livelihoods from people living along the river floodplain and feedback on water ressources. The study uses a mixed method approach, combining hydrological analyses, literature review and data collection from surveys on stakeholders and key informants level in the middle Senegal valley. Our results suggest that in all the Senegal river valley, socio-ecological changes are driven by new hydrological conditions. If dam management benefit for peoples with electrification and development of an irrigated agriculture, it has also emphasized the floodplain degradation. Flooded area has decline and are more irregular, causing an erosion of floodplain supporting services (traditional activities as fishing, grazing and flood-recession agriculture). These conditions reduce peoples' livelihood possibilities and irrigation is the only regular activity. As a feedback, irrigated agriculture increases withdrawals in the river and, recently, in aquifers posing a new uncertainty on water

    By applying a fed-batch strategy, production of Penicillium occitanis mannanases could be almost doubled as compared to a batch cultivation on acacia seeds (76 versus 41 U/mL). Also, a 10-fold increase of enzyme activities was observed from shake flask fermentation to the fed-batch fermentation. These production levels were 3-fold higher than those obtained on coconut meal. The high mannanase production using acacia seeds powder as inducer substrate showed the suitability of this culture process for industrial-scale development. PMID:23724314

    Malaria transmission in Senegal is highly stratified, from low in the dry north to moderately high in the moist south. In northern Senegal, along the Senegal River Valley and in the Ferlo semi-desert region, annual incidence is less than five cases per 1000 inhabitants. Many nomadic pastoralists have permanent dwellings in the Ferlo Desert and Senegal River Valley, but spend dry season in the south with their herds, returning north when the rains start, leading to a concern that this population could contribute to ongoing transmission in the north. A modified snowball sampling survey was conducted at six sites in northern Senegal to determine the malaria prevention and treatment seeking practices and parasite prevalence among nomadic pastoralists in the Senegal River Valley and the Ferlo Desert. Nomadic pastoralists aged 6 months and older were surveyed during September and October 2014, and data regarding demographics, access to care and preventive measures were collected. Parasite infection was detected using rapid diagnostic tests (RDTs), microscopy (thin and thick smears) and polymerase chain reaction (PCR). Molecular barcodes were determined by high resolution melting (HRM). Of 1800 participants, 61% were male. Sixty-four percent had at least one bed net in the household, and 53% reported using a net the night before. Only 29% had received a net from a mass distribution campaign. Of the 8% (142) who reported having had fever in the last month, 55% sought care, 20% of whom received a diagnostic test, one-third of which (n = 5) were reported to be positive. Parasite prevalence was 0.44% by thick smear and 0.50% by PCR. None of the molecular barcodes identified among the nomadic pastoralists had been previously identified in Senegal. While access to and utilization of malaria control interventions among nomadic pastoralists was lower than the general population, parasite prevalence was lower than expected and sheds doubt on the perception that they are a

    Plant associations with protective ants are widespread among angiosperms, but carry the risk that ants will deter pollinators as well as herbivores. Such conflict, and adaptations to ameliorate or prevent the conflict, have been documented in African and neotropical acacias. Ant-acacia associations occur in Australia, but little is known of their ecology. Moreover, recent phylogenetic evidence indicates that Australian acacias are only distantly related to African and American acacias, providing an intercontinental natural experiment in the management of ant-pollinator conflict. We examined four populations of Acacia myrtifolia over a 400-km environmental gradient in southeastern Australia using ant and pollinator exclusion as well as direct observation of ants and pollinators to assess the potential for ant-pollinator conflict to affect seed set. Native bees were the only group of floral visitors whose visitation rates were a significant predictor of fruiting success, although beetles and wasps may play an important role as "insurance" pollinators. We found no increase in pollinator visitation or fruiting success following ant exclusion, even with large sample sizes and effective exclusion. Because ants are facultative visitors to A. myrtifolia plants, their presence may be insufficient to interfere greatly with floral visitors. It is also likely that the morphological location of extrafloral nectaries tends to draw ants away from reproductive parts, although we commonly observed ants on inflorescences, so the spatial separation is not strict. A. myrtifolia appears to maintain a generalized mutualism over a wide geographic range without the need for elaborate adaptations to resolve ant-pollinator conflict.

    This study aimed to review knowledge, attitudes and practices related to sexual transmitted diseases (STD) and HIV/AIDS among men who have sex with men (MSM) in Senegal. The study was undertaken from February 1st to June 30th 2007, in three capitals cities in Senegal (one national, and two regional). It concerned the MSM that benefited from at least one of services of an MSM association. Studied variables included socio demographic characteristics, sexual practices, as well as knowledge and attitudes related to STDs and VIH/AIDS. Interviews took place during appointments obtained by direct phone call or by two MSM leaders intermediary. Data were seized and analyzed with Epi2000 Software. Among 245 registered MSM, 63 had a precise contact (address and/or phone number), and 49 aged in average of 25 years were investigated. Among them, one was illiterate, five studied Koran, seven Arab and 36 French. The socio-professional categories differentiated two officials, two merchants, one mechanic, one fighter, five artists, five restorers, seven tailors, 11 students, and 15 unemployed. The associations, to which 35 HSH belonged, were related to sexuality (66%), religion (20%), social matters (8%) and economy (6%). Sexual habits, according to anal intercourse, differentiated the "Ubbi" or receptive/passive (57%), the "Yoos" or incertif/active (25%), the "Ubbi/Yoos" who play the two roles (14%) and the "neitherUbbi/norYoos" who had other practices than anal (4%). Practices between men, concerned mutual strokes (100%), fellatio (61%) and anal intercourse (49%), counted 45% for remuneration, 35% of multi-unprotected partnership, and 12% of breaking condom. Practices with women were reported by 15 MSM (31%). Concerning STDs, at least one sign was reported by 43 MSM, one transmission way by 42, one mean of protection by 47; and the first recourse was a health system for 36 MSM.

    The present study assessed the relations between reading anxiety, classroom anxiety, language motivation, and readers' self-perception for a sample of Arab-American students in Arabic classes. The effects of sex, grade, and years studying Arabic on academic achievement were examined as well. Measures were administered to 118 middle school students (56 boys, 62 girls; M age = 13.0 yr., SD = 0.8), and teachers reported academic grades in Arabic. Reading anxiety was significantly correlated with classroom anxiety and reader self-perception. Classroom anxiety scores were significantly correlated with motivation and reader self-perception. Significant positive correlations were found between language motivation and reader self-perception scores, and between years studying Arabic and reader self-perception scores. Boys in the second year of Arabic had significantly lower classroom anxiety than girls, and students in Grade 7 had higher reader self-perception than those in Grade 8. Classroom anxiety, language motivation, and reader self-perception significantly predicted Arabic achievement. Pedagogical implications are discussed.

    Virginity is part of our existence in the world as embodied sexual subjects. While many meanings are associated with virginity, in most of the Arab world virginity relates to the presence of a hymen and extends to encompass the honor of the Arab community, and virginity loss commonly relate to first vaginal intercourse. This study explored the meanings of virginity from the perspectives of Arab and Arab American women. A qualitative phenomenological approach, informed by the philosophy of Maurice Merleau-Ponty, was used to conduct in-depth interviews with ten women. We identified one over-arching theme Virginity as Identity, and two major themes Embodiment of Virginity and “We are Arabs.” To reach an embodied virginity, participants went through a disembodied virginity process, reflecting society’s perceptions and values of virginity related to anatomical presence of a hymen and society’s honor. “We are Arabs” describes the ways women identified with the Arab ethnic identity as a shared overall identification, but differed from one lived experience to another, and influenced how participants embodied virginity. Our participants provided a better understanding of the diverse meanings of virginity that move beyond the binary of virginity and virginity loss, and into a spectrum of embodied meanings. Findings suggest the need for future research around sexuality in Arab Americans with attention to socio-political contexts in order to understand the nature and context of sexual initiation and its impact on sexual behaviors and well-being.

    Arab adolescents' commitments to their own self-development, their family, their extended family, the Arab people, and their village were explored. The sample consisted of 662 Arab adolescents in 12th grade in 7 high schools in Arab villages, Arab towns, and mixed towns (Jews and Arabs) in Israel. The findings reflect the unique situation of Arab adolescents living in Israel. The polarity found between individualistic and collectivistic ideas, in terms of commitment, illustrates the cultural transformation that Arab society in Israel is currently undergoing.

    The Arabic language is acquired by its native speakers both as a regional spoken Arabic dialect, acquired in early childhood as a first language, and as the more formal variety known as Modern Standard Arabic (MSA), typically acquired later in childhood. These varieties of Arabic show a range of linguistic similarities and differences. Since previous psycholinguistic research in Arabic has primarily used MSA, it remains to be established whether the same cognitive properties hold for the dialects. Here we focus on the morphological level, and ask whether roots and word patterns play similar or different roles in MSA and in the regional dialect known as Southern Tunisian Arabic (STA). In two intra-modal auditory-auditory priming experiments, we found similar results with strong priming effects for roots and patterns in both varieties. Despite differences in the timing and nature of the acquisition of MSA and STA, root and word pattern priming was clearly distinguishable from form-based and semantic-based priming in both varieties. The implication of these results for theories of Arabic diglossia and theories of morphological processing are discussed. PMID:24347753

    To determine the smoking behavior in pregnant Arab American women who attended a Women, Infant and Children (WIC) program at a local county public health clinic and compare the incidence of smoking behaviors of pregnant Arab American women with pregnant women who were not Arab Americans. Data were extracted from a computer database that contained information from health history charts of pregnant Arab and non-Arab American women. The study sample was 830 women, 823 of whom were Arab American participants enrolled in the WIC program in Michigan. Approximately 6% of pregnant Arab Americans smoked during pregnancy. The prevalence of smoking behavior among pregnant Arab American women was similar to that of smoking behaviors of Hispanics and Asian Americans in the United States. Although smoking behavior is a serious problem among Arab American immigrants in general and in the Arab world in particular, cultural factors that support healthy behavior during pregnancy in the Arab culture seem to limit the use of tobacco in pregnant women. Nurses who care for Arab American pregnant women can use this information to better inform their care of these patients.

    The analysis of the spatial and temporal variability of climate parameters is crucial to study the impact of climate-sensitive vector-borne diseases such as malaria. The use of malaria models is an alternative way of producing potential malaria historical data for Senegal due to the lack of reliable observations for malaria outbreaks over a long time period. Consequently, here we use the Liverpool Malaria Model (LMM), driven by different climatic datasets, in order to study and validate simulated malaria parameters over Senegal. The findings confirm that the risk of malaria transmission is mainly linked to climate variables such as rainfall and temperature as well as specific landscape characteristics. For the whole of Senegal, a lag of two months is generally observed between the peak of rainfall in August and the maximum number of reported malaria cases in October. The malaria transmission season usually takes place from September to November, corresponding to the second peak of temperature occurring in October. Observed malaria data from the Programme National de Lutte contre le Paludisme (PNLP, National Malaria control Programme in Senegal) and outputs from the meteorological data used in this study were compared. The malaria model outputs present some consistencies with observed malaria dynamics over Senegal, and further allow the exploration of simulations performed with reanalysis data sets over a longer time period. The simulated malaria risk significantly decreased during the 1970s and 1980s over Senegal. This result is consistent with the observed decrease of malaria vectors and malaria cases reported by field entomologists and clinicians in the literature. The main differences between model outputs and observations regard amplitude, but can be related not only to reanalysis deficiencies but also to other environmental and socio-economic factors that are not included in this mechanistic malaria model framework.

    This study was performed to determine the effect of xanthan, guar, CMC and gum acacia on functional and pasting properties of starch isolated from water chestnut (Trapa bispinosa). Morphological properties of water chestnut starch with CMC were studied by scanning electron microscopy (SEM). The addition of hydrocolloids significantly enhanced the solubility of water chestnut starch (WCS) while reduced swelling power and freeze-thaw stability. The hydrophilic tendency of WCS was increased by xanthan gum; however, with addition of gum acacia it decreased significantly. Starch was modified with guar and gum acacia exhibited highest% syneresis. Guar gum was found to be effective in increasing the clarity of water chestnut starch paste. The addition of CMC significantly reduced the pasting temperature of WCS indicating ease of gelatinization. The setback was accelerated in the presence of xanthan gum but gum acacia delayed this effect during the cooling of the starch paste. Only xanthan gum was found to be effective in increasing breakdown showing good paste stability of WCS. Copyright © 2017 Elsevier B.V. All rights reserved.

  15. Republic of Senegal. Country profile.

    Gold, D

    1985-04-01

    The demographic and economic characteristics and some of the cultural traditions of the Republic of Senegal are described. Senegal obtained its independence from France in 1960. Despite the fact that the majority of the population derives its living from agriculture, the country must import additional food staples to feed its population. Conditions contributing to poor crop yields in recent years include 1) the frequent occurrence of droughts, 2) soil depletion caused by overintensive cultivation practices, and 3) land dessication caused by poor forestry management. In 1984 crop yields were only 10% of the normal crop yields. The government under the leadership of the president, Adbou Diouf, is currently developing plans to improve agricultural conditions and to encourage the industrial development of the country. The tourist industry is also growing. In 1976 Senegal conducted it 1st national census. According to the census the total population was 5,068,741 and the population growth rate was 2.6%. The US Census Bureau estimates that the population growth rate is now 3.2% and that 654,000 people were added to the population between 1976 and 1985. 27% of the population is urban, and the majority of the urban population resides in Dakar. In recent years, the rate of rural to urban migration increased rapidly as a result of the deteriorating agricultural conditions. The population is unevenly distributed throughout the country; 82% of the population lives in 39% of the country's territory. In 1977, 18% of the population lived in housing with electricity, and in 1983, 37% of the population lived in housing with running water. Most rural residents live in villages consisting of clusters of clay structures with thatched roofs and dirt floors. Most of the urban poor live in crowded shantytowns, which lack urban services. More than 1/2 of the population is under the age of 18. According to the 1978 World Fertility Survey, 83% of all women of reproductive age are married

    Introducing nitrogen-fixing bacteria as an inoculum in association with legume crops is a common practice in agriculture. However, the question of the evolution of these introduced microorganisms remains crucial, both in terms of microbial ecology and agronomy. We explored this question by analyzing the genetic and symbiotic evolution of two Bradyrhizobium strains inoculated on Acacia mangium in Malaysia and Senegal 15 and 5 years, respectively, after their introduction. Based on typing of several loci, we showed that these two strains, although closely related and originally sampled in Australia, evolved differently. One strain was recovered in soil with the same five loci as the original isolate, whereas the symbiotic cluster of the other strain was detected with no trace of the three housekeeping genes of the original inoculum. Moreover, the nitrogen fixation efficiency was variable among these isolates (either recombinant or not), with significantly high, low, or similar efficiencies compared to the two original strains and no significant difference between recombinant and nonrecombinant isolates. These data suggested that 15 years after their introduction, nitrogen-fixing bacteria remain in the soil but that closely related inoculant strains may not evolve in the same way, either genetically or symbiotically. In a context of increasing agronomical use of microbial inoculants (for biological control, nitrogen fixation, or plant growth promotion), this result feeds the debate on the consequences associated with such practices.

    2013-11-27

    Honey is a good source of several important chemical compounds and antioxidants and is harvested throughout the year. However, no study has determined how their contents change over the years. The aim of the present research was to investigate the changes in the phenolics, flavonoids and antioxidant properties, as well as other physicochemical properties, of Malaysian acacia honey collected during different months during a two year period. The DPPH (1,1-diphenyl-2-picrylhydrazyl) and FRAP (ferric reducing antioxidant power) methods were used to determine the total antioxidant activity of the honey samples. Generally, honey samples collected in the beginning and the middle of the year tended to have higher sugar content, which may be attributed to its high acidic nature and low moisture content. There was a gradual increase in the phenolic content of the acacia honey samples collected between September 2010 and December 2010. The honey sample collected at the beginning of the year (January) showed the highest color intensity and was dark amber in color. It also contained the highest concentration of phenolic compounds (341.67 ± 2.94 mg(gallic acid)/kg), the highest flavonoid content (113.06 ± 6.18 mg(catechin)/kg) and the highest percentage of DPPH inhibition and the highest FRAP value, confirming its high antioxidant potential. There was a positive correlation between DPPH and total phenolic content, suggesting that phenolic compounds are the strongest contributing factor to the radical scavenging activity of Malaysian acacia honeys. Overall, our results indicated that there were significant seasonal variations in the antioxidant potentials of honey over the two year period and the time of honey collection affects its physicochemical properties. Therefore, acacia honey from Malaysia should ideally be collected during the dry season, particularly in the months of January, May and June.

    Data about Arab-Americans, a growing ethnic minority, are not routinely collected in vital statistics, registry, or administrative data in the USA. The difficulty in identifying Arab-Americans using publicly available data sources is a barrier to health research about this group. Here, we validate an empirically based probabilistic Arab name algorithm (ANA) for identifying Arab-Americans in health research. We used data from all Michigan birth certificates between 2000 and 2005. Fathers' surnames and mothers' maiden names were coded as Arab or non-Arab according to the ANA. We calculated sensitivity, specificity, and positive (PPV) and negative predictive values (NPV) of Arab ethnicity inferred using the ANA as compared to self-reported Arab ancestry. Statewide, the ANA had a specificity of 98.9%, a sensitivity of 50.3%, a PPV of 57.0%, and an NPV of 98.6%. Both the false-positive and false-negative rates were higher among men than among women. As the concentration of Arab-Americans in a study locality increased, the ANA false-positive rate increased and false-negative rate decreased. The ANA is highly specific but only moderately sensitive as a means of detecting Arab ancestry. Future research should compare health characteristics among Arab-American populations defined by Arab ancestry and those defined by the ANA.

It describes the problems that Arab policy-makers must address in order to set the Arab world on the road to scientific and technological self-reliance, with special emphasis on the shortcomings of the Arab education system and the problem of the brain drain. It also discusses the development of Arab policies on science and technology in the context of the need to democratize Arab society as a prerequisite to real advancement. And finally it surveys the efforts that Arab policy-makers have made in recent years to formulate coherent inter-Arab policies on science and technology. Arab national policy on science and technology for development must be formulated in accordance with the concepts of international co-operation and take full advantage of the vehicles for co-operation that exist today.

    Aim Many Australian Acacia species have been planted around the world, some are highly valued, some are invasive, and some are both highly valued and invasive. We review global efforts to minimize the risk and limit the impact of invasions in this widely used plant group. Location Global. Methods Using information from literature sources, knowledge and experience of the authors, and the responses from a questionnaire sent to experts around the world, we reviewed: (1) a generalized life cycle of Australian acacias and how to control each life stage, (2) different management approaches and (3) what is required to help limit or prevent invasions. Results Relatively few Australian acacias have been introduced in large numbers, but all species with a long and extensive history of planting have become invasive somewhere. Australian acacias, as a group, have a high risk of becoming invasive and causing significant impacts as determined by existing assessment schemes. Moreover, in most situations, long-lived seed banks mean it is very difficult to control established infestations. Control has focused almost exclusively on widespread invaders, and eradication has rarely been attempted. Classical biological control is being used in South Africa with increasing success. Main conclusions A greater emphasis on pro-active rather than reactive management is required given the difficulties managing established invasions of Australian acacias. Adverse effects of proposed new introductions can be minimized by conducting detailed risk assessments in advance, planning for on-going monitoring and management, and ensuring resources are in place for long-term mitigation. Benign alternatives (e.g. sterile hybrids) could be developed to replace existing utilized taxa. Eradication should be set as a management goal more often to reduce the invasion debt.

    The chemical composition of Acacia catechu, Schinopsis balansae, and Acacia mearnsii proanthocyanidins has been determined using a novel analytical approach that rests on the concerted use of quantitative (31)P NMR and two-dimensional heteronuclear NMR spectroscopy. This approach has offered significant detailed information regarding the structure and purity of these complex and often elusive proanthocyanidins. More specifically, rings A, B, and C of their flavan-3-ol units show well-defined and resolved absorbance regions in both the quantitative (31)P NMR and HSQC spectra. By integrating each of these regions in the (31)P NMR spectra, it is possible to identify the oxygenation patterns of the flavan-3-ol units. At the same time it is possible to acquire a fingerprint of the proanthocyanidin sample and evaluate its purity via the HSQC information. This analytical approach is suitable for both the purified natural product proanthocyanidins and their commercial analogues. Overall, this effort demonstrates the power of the concerted use of these two NMR techniques for the structural elucidation of natural products containing labile hydroxy protons and a carbon framework that can be traced out via HSQC.

In this paper, we use mobile phone records to explore the impact of agricultural activity on the communication and mobility patterns of the inhabitants of Senegal. We find two peaks of phone calls activity emerging during the growing season. Moreover, during the harvest period, we detect an increase in the migration flows throughout the country. However, religious holidays also shape the mobility patterns of the Senegalese people. Hence, in the light of our results, agricultural activity and religious holidays are the primary drivers of mobility inside the country.

    Rift Valley Fever (RVF) virus (Family Bunyaviridae) is an arthropod-borne RNA virus that infects primarily domestic ruminants and occasionally humans. RVF epizootics are characterized by numerous abortions and mortality among young animals. In humans, the illness is usually characterized by a mild self-limited febrile illness, which could progress to more serious complications. RVF virus is widespread and endemic in many regions of Africa. In Western Africa, several outbreaks have been reported since 1987 when the first major one occurred at the frontier of Senegal and Mauritania. Aiming to evaluate the spreading and molecular epidemiology in these countries, RVFV isolates from 1944 to 2008 obtained from 18 localities in Senegal and Mauritania and 15 other countries were investigated. Our results suggest that a more intense viral activity possibly took place during the last century compared to the recent past and that at least 5 introductions of RVFV took place in Senegal and Mauritania from distant African regions. Moreover, Barkedji in Senegal was possibly a hub associated with the three distinct entries of RVFV in West Africa. PMID:22539961

Monitoring vegetation changes in hyper arid zones is important because any reduction in the vegetation cover in these areas can lead to a considerable reduction in the carrying capacity of the ecological system. This study focuses on the impact of climate fluctuations on the acacia population in the southern Arava valley, Israel. The period of this survey includes a sequence of dry years with no flashfloods in most of the plots that ended in two years with vast floods. Arid zone acacia trees play a significant role in the desert ecosystem by moderating the extreme environmental conditions including radiation, temperature, humidity and precipitation. The trees also provide nutrients for the desert dwellers. Therefore, acacia trees in arid zones are considered to be `keystone species', because they have major influence over both plants and animal species, i.e., biodiversity. Long term monitoring of the acacia tree population in this area can provide insights into long term impacts of climate fluctuations on ecosystems in arid zones. Since 2000, a continuous yearly based survey on the three species of acacia population in seven different plots is conducted in the southern Arava (established by Shalmon, ecologist of the Israel nature and parks authority). The seven plots representing different ecosystems and hydrological regimes. A yearly based population monitoring enabled us to determine the mortality and recruitment rate of the acacia populations as well as growing rates of individual trees. This survey provides a unique database of the acacia population dynamics during a sequence of dry years that ended in a vast flood event during the winter of 2010. A lack of quantitative, nondestructive methods to estimate and monitor stress status of the acacia trees, led us to integrate remote sensing tools (ground and air-based) along with conventional field measurements in order to develop a long term monitoring of acacia

    The bark of Acacia mearnsii De Wild. (black wattle) contains significant amounts of water-soluble components acalled "wattle tannin". Following the discovery of its strong antioxidant activity, a wattle tannin dietary supplement has been developed and as part of developing new dietary supplements, a literature search was conducted using the SciFinder data base for " Acacia species and their biological activities". An analysis of the references found indicated that the name of Acacia nilotica had been changed to Vachellia nilotica , even though the name of the genus Acacia originated from its original name. This review briefly describes why and how the name of A. nilotica changed. Tannin has been analyzed using the Stiasny method when the tannin is used to make adhesives and the hide-powder method is used when the tannin is to be used for leather tanning. A simple UV method is also able to be used to estimate the values for both adhesives and leather tanning applications. The tannin content in bark can also be estimated using NIR and NMR. Tannin content estimations using pyrolysis/GC, electrospray mass spectrometry and quantitative 31 P-NMR analyses have also been described. Tannins consists mostly of polyflavanoids and all the compounds isolated have been updated. Antioxidant activities of the tannin relating to anti-tumor properties, the viability of human neuroblastoma SH-SY5Y cells and also anti-hypertensive effects have been studied. The antioxidant activity of proanthocyanidins was found to be higher than that of flavan-3-ol monomers. A total of fourteen papers and two patents reported the antimicrobial activities of wattle tannin. Bacteria were more susceptible to the tannins than the fungal strains tested. Several bacteria were inhibited by the extract from A. mearnsii bark. The growth inhibition mechanisms of E. coli were investigated. An interaction between extracts from A. mearnsii bark and antibiotics has also been studied. The extracts from A. mearnsii

    The difficult and tense political climate Arab populations are currently facing may be exacerbating mental health issues, reducing forms of social support in friend circles, and decreasing the desire to seek health care. There is room to better understand the mental health needs of Arab women residing in the United States and to develop policies and interventions that keep these women safe and in care. This column reviews two recent studies; the first examines barriers to reporting intimate partner violence and depression among Arab American women and the second highlights stressors and social support for Arab women immigrants throughout their immigration experience. © 2017 AWHONN, the Association of Women’s Health, Obstetric and Neonatal Nurses.

    Since 1981, Arab oil revenues have declined by about 40-50%. This has had an enormous impact on the Arab economies as well as on economic and political relations between the Arab world, the industrialised world and the Third world. This book reviews how lower oil revenues have affected Arab countries and the international economy. It also considers the future prospects for Arab oil and the world oil industry. It analyses the various assessment of the life span of oil, the forecasts concerning the development of alternative sources of energy and the factors governing the demand for oil. Although the outlookmore » for the Arab economies appears gloomy in many respects, the book argues that there is potential within the Arab world to overcome the decline in oil revenues.

    1980-04-01

    Development projects in the Arab world have enormous investment requirements that Arab banks at present can only partially handle due to: (1) the low level of personal savings in a number of Arab countries as a result of low income levels; (2) the low capitalization of most Arab banks relative to the volume of lending activity required; (3) the reluctance of oil surplus countries to deposit any sizeable part of their funds with their own banks instead of foreign banks. Funds available in the currencies of the oil surplus countries are very limited compared to the volume of funds requiredmore » for projects. It is necessary therefore that the majority of loans be made in foreign currencies, making it necessary for Arab banks to have high international credit status. Arab banking practices and laws, which vary from country to country, are not compatible with the requirements of international lending or the establishment of well-developed financial markets. Some of the banks' organizational structures and internal practices may have become so entrenched as to make any transition not feasible. In some cases it may be more practical to establish a new financial institution with different orientations and activities than to transform the existing one. Another major constraint of the Arab banking environment is the lack of a permanent intermediary, acceptable to both the surplus countries' banks and to the borrowers. The final constraint discussed, the political environment, has prompted many Arab countries to enact legislation to guarantee a politically stable environment to safeguard risk against expropriation, nationalization, or freezing of assets.

    Cancer is a leading cause of death worldwide and its development is frequently associated with oxidative stress-induced by carcinogens such as arsenicals. Most foods are basically health-promoting or disease-preventing and a typical example of such type is honey. This study was undertaken to investigate the ameliorative effects of Acacia honey on sodium arsenite-induced oxidative stress in the heart, lung and kidney tissues of male Wistar rats. Male Wistar albino rats divided into four groups of five rats each were administered distilled water, Acacia honey (20%), sodium arsenite (5 mg/kg body weight), Acacia honey, and sodium arsenite daily for one week. They were sacrificed anesthetically using 60 mg/kg sodium pentothal. The tissues were used for the assessment of glutathione peroxidase, catalase, and superoxide dismutase activities, protein content and lipid peroxidation. Sodium arsenite significantly (P < 0.05) suppressed the glutathione peroxidase, catalase, superoxide dismutase activities with simultaneous induction of lipid peroxidation. Administration of Acacia honey significantly increased (P < 0.05) glutathione peroxidase, catalase, and superoxide dismutase activities with concomitant suppression of lipid peroxidation as evident by the decrease in malondialdehyde level. From the results obtained, Acacia honey mitigates sodium arsenite induced-oxidative stress in male Wistar albino rats, which suggest that it may attenuate oxidative stress implicated in chemical carcinogenesis.

    The CENTURY model was used to simulate changes in total system carbon resulting from land-use history (1850–2000), and impacts of climatic changes and improved land-use management practices in Senegal. Results show that 0.477 Gtons of carbon have been lost from 1850 to 2000. Improved management practices have the potential of increasing carbon levels by 0.116 Gtons from 2000 to 2100. Potential to store carbon exists for improved forest management and agriculture practices in southern Senegal. Potential climatic changes decrease plant production (30 percent), total system carbon (14 percent), and the potential to store carbon from improved management practices (31 percent).

    Abstract Background and Aims This study investigates the structural diversity of the secondary xylem of 54 species of Acacia from four taxonomic sections collected across five climate regions along a 1200 km E–W transect from sub-tropical [approx. 1400 mm mean annual precipitation (MAP)] to arid (approx. 240 mm MAP) in New South Wales, Australia. Acacia sensu stricto (s.s.) is a critical group for understanding the effect of climate and phylogeny on the functional anatomy of wood. Methods Wood samples were sectioned in transverse, tangential and radial planes for light microscopy and analysis. Key Results The wood usually has thick-walled vessels and fibres, paratracheal parenchyma and uniseriate and biseriate rays, occasionally up to four cells wide. The greater abundance of gelatinous fibres in arid and semi-arid species may have ecological significance. Prismatic crystals in chambered fibres and axial parenchyma increased in abundance in semi-arid and arid species. Whereas vessel diameter showed only a small decrease from the sub-tropical to the arid region, there was a significant 2-fold increase in vessel frequency and a consequent 3-fold decrease in the vulnerability index. Conclusions Although the underlying phylogeny determines the qualitative wood structure, climate has a significant influence on the functional wood anatomy of Acacia s.s., which is an ideal genus to study the effect of these factors.

    1997-04-01

    The amount of deposited pyrolytic carbon (resulting from the cracking of volatile matter) was found to depend on wood species and carbonization conditions, such as temperature and heating rate. Maximum pyrolytic carbon deposition in both the acacia and eucalyptus wood chars has been observed at a carbonization temperature of 800 C. Rapid carbonization (higher heating rate) of wood significantly reduces the amount of deposited pyrolytic carbon in resulting chars. Results also indicate that the amount of deposited pyrolytic carbon in acacia wood char is less than that in eucalyptus wood char.

    Help-seeking processes provide critical links between the onset of mental health problems and the provision of professional care. But little is known about these processes in the Arab world, and still less in transnational, comparative terms. This is the first study to compare help-seeking processes among Muslim Arab female students in Jordan, the United Arab Emirates and Israel. The present study compares the attitudes of Arab Muslim female students from Israel, Jordan and the United Arab Emirates (UAE) towards mental health treatment. A convenience sample of 262 female Muslim-Arab undergraduate university students from Jordan, United Arab Emirates (UAE) and Arab students in Israel completed a modified Orientation for Seeking Professional Help (OSPH) Questionnaire. Data revealed that nationality was not statistically significant as a variable in a positive attitude towards seeking professional help; year of study, marital status and age were found to be significant predictors of a positive attitude towards seeking help. High proportions of respondents among the nationalities referred to God through prayer during times of psychological distress. The discussion considers implications for professional service delivery and programme development. Future research could extrapolate findings to other Arab countries and to Arab peoples living in the non-Arab world.

    Breast cancer is one of the most common types of cancers affecting women worldwide. The main objective of this study was to assess and compare research activity in breast cancer in Arab countries with non-Arab Middle Eastern countries. Publications about "breast cancer" as a research topic were retrieved using the ISI Web of Science database. Analysis was confined to original research and review articles. Research productivity was assessed by assessing number of publications and time trend of these publications, names of journals, citation analysis, top 10 active institutions as well as country contribution to breast cancer research. The quantity and quality of publications from Arab countries in addition to 3 other Middle East countries (Turkey, Iran and Israel) were assessed and compared using the h-index tool. A total of 1658 original research and review articles about "breast cancer" were published from Arab countries. Annual research productivity from Arab countries in the field of "breast cancer" was negligible but showed a significant increase in the last decade. Retrieved documents had relatively high citation parameters as measured by h-index of 61 and average citations of 17.46 per document. The highest research productivity was from Egypt with a total publication of 582 (35.10%). Cairo University with a total of 149 (8.99%) publications had the highest research productivity among institutions in Arab world. Forty four documents (2.65%) of breast cancer documents were published in Saudi Medical Journal. Arab researchers collaborated mostly with researchers from the United States of America (305; 18.40%) in breast cancer research. Compared with other non-Arab Middle Eastern countries, Arab countries had higher research productivity than some countries and lower than others, particularly Israel. The present data reveals a good contribution of some Arab countries to the field of "breast cancer" research. There is a gap between Arab countries and Israel in

    The Sahara desert transports large quantities of dust over the Sahelian region during the Northern Hemisphere winter and spring seasons (December-April). In episodic events, high dust concentrations are found at the surface, negatively impacting respiratory health. Bacterial meningitis in particular is known to affect populations that live in the Sahelian zones, which is otherwise known as the meningitis belt. During the winter and spring of 2012, suspected meningitis cases (SMCs) were with three times higher than in 2013. We show higher surface particular matter concentrations at Dakar, Senegal and elevated atmospheric dust loading in Senegal for the period of 1 January-31 May during 2012 relative to 2013. We analyze simulated particulate matter over Senegal from the Weather Research and Forecasting (WRF) model during 2012 and 2013. The results show higher simulated dust concentrations during the winter season of 2012 for Senegal. The WRF model correctly captures the large dust events from 1 January-31 March but has shown less skill during April and May for simulated dust concentrations. The results also show that the boundary conditions are the key feature for correctly simulating large dust events and initial conditions are less important.

    Incidence rates of congenital disorders among the 350 million inhabitants of Arab countries could be influenced via the people's demographic and cultural characteristics. Arabs usually marry at a young age and have large families. They share certain core cultural values and beliefs, with the family accepted as the central structure of society. Consanguineous marriage is favored and respected in most if not all Arab communities, and intrafamilial unions currently account for 20-50% of all marriages. First-cousin unions are especially popular and constitute almost one quarter of all marriages in many Arab countries. Consequently, autosomal recessive (AR) dysmorphic syndromes constitute a considerable proportion of all birth defects among Arabs. Arab geneticists, with their persistent commitment to advancing research, have contributed to the description of a number of rare and new AR syndromes with the identification of novel genes. The collaboration with research teams in high-income countries resulted in a plethora of data on pathogenic variants and their function in causing dysmorphic syndromes. There could still be a considerable number of rare dysmorphic syndromes that prevail among Arabs which are not hitherto described and whose underlying molecular pathologies are not yet defined. Arab countries should thus strive to deploy DNA diagnostics and to build research capability around local priorities. Furthermore, a characterization of the prevailing genetic disorders in each geographic location, together with their mutations, is needed to plan for appropriate screening and testing protocols. An overview of consanguinity in Arab countries and examples of dysmorphology syndromes associated with consanguinity with their available molecular bases will be discussed. © 2014 S.

    The stemming is the process of transforming a word into its root or stem, hence, it is considered as a crucial pre-processing step before tackling any task of natural language processing or information retrieval. However, in the case of Arabic language, finding an effective stemming algorithm seems to be quite difficult, since the Arabic language has a specific morphology, which is different from many other languages. Although, there exist several algorithms in literature addressing the Arabic stemming issue, unfortunately, most of them are restricted to a limited number of words, present some confusions between original letters and affixes, and usually employ dictionary of words or patterns. For that purpose, we propose the design and implementation of a novel Arabic light stemmer, which is based on some new rules for stripping prefixes, suffixes and infixes in a smart way. And in our knowledge, it is the first work dealing with Arabic infixes with regards to their irregular rules. The empirical evaluation was conducted on a new Arabic data-set (called ARASTEM), which was conceived and collected from several Arabic discussion forums containing dialectical Arabic and modern pseudo-Arabic languages. Hence, we present a comparative investigation between our new stemmer and other existing stemmers using Paice's parameters, namely: Under Stemming Index (UI), Over Stemming Index (OI) and Stemming Weight (SW). Results show that the proposed Arabic light stemmer maintains consistently high performances and outperforms several existing light stemmers.

    Anopheles funestus is one of the major malaria vectors in tropical Africa, notably in Senegal. The highly anthropophilic and endophilic behaviours of this mosquito make it a good target for vector control operations through the use of insecticide treated nets, long-lasting insecticide nets and indoor residual spraying. However, little is known about patterns of resistance to insecticides and the underlying resistance mechanisms in field populations of this vector in Senegal. Here, we assessed the susceptibility status of An. funestus populations from Gankette Balla, located in northern Senegal and investigated the potential resistance mechanisms. WHO bioassays indicated that An. funestus is resistant to lambda-cyhalothrin 0.05 % (74.64 % mortality), DDT 4 % (83.36 % mortality) and deltamethrin 0.05 % (88.53 % mortality). Suspected resistance was observed to permethrin 0.75 % (91.19 % mortality), bendiocarb 0.1 % (94.13 % mortality) and dieldrin 4 % (96.41 % mortality). However, this population is fully susceptible to malathion 5 % (100 % mortality) and fenitrothion 1 % (100 % mortality). The microarray and qRT-PCR analysis indicated that the lambda-cyhalothrin resistance in Gankette Balla is conferred by metabolic resistance mechanisms under the probable control of cytochrome P450 genes among which CYP6M7 is the most overexpressed. The absence of overexpression of the P450 gene, CYP6P9a, indicates that the resistance mechanism in Senegal is different to that observed in southern Africa. This study represents the first report of pyrethroid and DDT resistance in An. funestus from Senegal and shows that resistance to insecticides is not only confined to An. gambiae as previously thought. Therefore, urgent action should be taken to manage the resistance in this species to ensure the continued effectiveness of malaria control.

    Limited information is available about Arab Americans' smoking behaviors. The aim of this study was to describe Arab Americans' smoking behaviors and any relationship between tobacco dependence and acculturation. This was a cross-sectional study. Arab American smokers and ex-smokers (N = 96) participated in the study. Nicotine dependence, acculturation, and tobacco use questionnaires were used to measure the major variables. Analyses revealed a significant positive correlation between acculturation and tobacco dependence and between tobacco exposure and tobacco dependence. Arab Americans who behaved most like their ethnic peers and spent more time with Arab Americans were more dependent on nicotine.

    All waters, especially surface waters contain dissolved, suspended particles and/or inorganic matter, as well as several biological organisms, such as bacteria, algae or viruses. This material must be removed because it can affect the water quality that can cause turbidity and colour. The objective of this study is to develop water treatment process from Seri Alam (Johor, Malaysia) lake water resources by using natural coagulant Acacia auriculiformis pods through a jar test experiment. Jar test is designed to show the effectiveness of the water treatment. This process is a laboratory procedure that will simulate coagulation/flocculation with several parameters selected namely contact time, coagulant dosage and agitation speed. The most optimum percentage of colloids removal for each parameter is determined at 0.2 g, 90 min and 80 rpm. FESEM (Field-emission Scanning Electron Microscope) observed the small structures of final floc particles for optimum parameter in this study to show that the colloids coagulated the coagulant. All result showed that the Acacia auriculiformis pods can be a very efficient coagulant in removing colloids from water.

    The Senegal River is regulated by 2 dams built in the 1980's by the "Organisation pour la Mise en Valeur du fleuve Sénégal" (OMVS), a river basin management organisation grouping Mali, Senegal and Mauritania. The initial objectives of OMVS, which were to regulate the Senegal flows in order to develop irrigated agriculture, produce hydropower and facilitate river navigation has been only partially met. The maintenance of the annual flood by the upstream dam (Manantali), initially to be phased out when irrigated agriculture would have replaced the traditional recession agriculture, is now scheduled to continue indefinitely on the basis of socio-economic and environmental concerns. This change of mindset has however not affected the management of the downstream dam (Diama). Initially conceived as a salt-wedge dam, its function evolved to a reservoir dam with a high and constant water level. During the dry season, the water level is maintained high and constant in order to reduce the pumping costs for the irrigated agriculture in the delta. During the flood season (July-October) the dam is primarily managed for risk avoidance: limit flooding downstream of the dam (especially the city of St. Louis) and secure the infrastructure of the dam itself. The permanent freshwater reservoir lake has adverse effects on ecosystems, on human and animal health and a high social cost for the traditional stakeholders of the deltaic floodplain (fishermen, livestock keepers and gatherers). Upstream of the reservoir there is an excess of stagnant freshwater and managers are confronted with the development of invasive species while substantial downstream flooding is essential for the estuarine ecosystems and local livelihoods. The presentation will review the different approaches to the management of the Diama reservoir and proposes different management scenarios and compares their economical, environmental, and social costs and benefits.

    Mustajel, S.Y.

    The dissertation discusses the implications of such capabilities for the ongoing Arab-Israeli confict within the context of traditional deterrence - especially nuclear deterrence - theory. The major focus is on the resulting balance of terror and how it is likely to determine the outcome of the Arab-Israeli conflict. In part 1, a brief survey of the present and planned nuclear power and nuclear-power-related facilities, installations, research institutions, and possible nuclear delivery means possessed by the Arabs and the Israelis is presented. This survey is based only on readily available information. Part 2 presents an examination of the implications of themore » introduction of nuclear military capabilties by both sides or either side in the Arab-Israeli conflict. Egypt, with whatever nuclear capability it has, or will have, is considered in this study to be part of the Arab camp even though it has recently signed a separate peace treaty with Israel. Then, suggestions, based on conclusions and findings are provided to countries involved on how to avoid the catastrophic consequences of introducing nuclear weapons into the Arab-Israeli confict. In order to avoid catastrophic consequences of introducing nuclear weapons into the Arab-Israeli conflict, it is suggested that there must be a general peace settlement, followed by denuclearization of the Middle East region.« less

    Research exploring the unmet supportive care needs of Arab cancer survivors is limited, with most conducted with immigrant groups. No study has compared the unmet supportive care needs of immigrant Arab cancer survivors with Arab cancer survivors living in their native country. To explore the unmet supportive care needs of both Arab Australian and Arab Jordanian cancer survivors. Arab people living in Sydney, Australia, and Amman, Jordan, and diagnosed with cancer within the last 5 years were invited to complete a questionnaire that measured unmet supportive care needs, depression, and language acculturation. Multiple regression analysis was performed to identify predictors of unmet supportive care needs. Seventy-seven Arab Jordanian and 66 Arab Australian cancer survivors were recruited. Australian participants were older than their Jordanian counterparts (61.5 vs 52.3 years; P < .001) and reported higher levels of overall unmet needs (44.9 vs 36.1; P = .012). Controlling for age and stage of cancer diagnosis, higher levels of depression (β = .34) and living in Australia (β = .26) were significant predictors of unmet needs and explained almost 17% of the variance. These findings have extended our understanding of the unmet supportive care needs of Arab cancer survivors and confirm disparities in unmet needs in immigrant populations. Greater attention is needed to ensure the supportive care needs are met for immigrant patients with cancer. Additional strategies to address physical and psychological needs are particularly needed in this group.

    In Senegal, great amounts of data are daily generated by medical activities such as consultation, hospitalization, blood test, x-ray, birth, death, etc. These data are still recorded in register, printed images, audios and movies which are manually processed. However, some medical organizations have their own software for non-standardized patient record management, appointment, wages, etc. without any possibility of sharing these data or communicating with other medical structures. This leads to lots of limitations in reusing or sharing these data because of their possible structural and semantic heterogeneity. To overcome these problems we have proposed a National Medical Information System for Senegal (SIMENS). As an integrated platform, SIMENS provides an EHR system that supports healthcare activities, a mobile version and a web portal. The SIMENS architecture proposes also a data and application integration services for supporting interoperability and decision making.

    The remote sensing technique has provided useful information to detect spatio-temporal changes in the land cover of tropical forests. Land cover characteristics derived from satellite image can be applied to the estimation of ecosystem services and biodiversity over an extensive area, and such land cover information would provide valuable information to global and local people to understand the significance of the tropical ecosystem. This study was conducted in the Acacia plantations and natural forest situated in the mountainous region which has different ecological characteristic from that in flat and low land area in Sarawak, Malaysia. The main objective of this study is to compare extract the characteristic of them by analyzing the ALOS/AVNIR2 images and ground truthing obtained by the forest survey. We implemented a ground-based forest survey at Aacia plantations and natural forest in the mountainous region in Sarawak, Malaysia in June, 2013 and acquired the forest structure data (tree height, diameter at breast height (DBH), crown diameter, tree spacing) and spectral reflectance data at the three sample plots of Acacia plantation that has 10 x 10m area. As for the spectral reflectance data, we measured the spectral reflectance of the end members of forest such as leaves, stems, road surface, and forest floor by the spectro-radiometer. Such forest structure and spectral data were incorporated into the image analysis by support vector machine (SVM) and object-base/texture analysis. Consequently, land covers on the AVNIR2 image were classified into three forest types (natural forest, oil palm plantation and acacia mangium plantation), then the characteristic of each category was examined. We additionally used the tree age data of acacia plantation for the classification. A unique feature was found in vegetation spectral reflectance of Acacia plantations. The curve of the spectral reflectance shows two peaks around 0.3μm and 0.6 - 0.8μm that can be assumed to

    Acacia catechu Willd ( Fabaceae ), commonly known as catechu, cachou, and black cutch, has been studied for its hepatoprotective, antipyretic, antidiarrheal, hypoglycemic, anti-inflammatory, immunomodulatory, antinociceptive, antimicrobial, free radical scavenging, and antioxidant activities. We evaluated the cytotoxic activity of ethanol extract of A. catechu seed (ACS) against SCC-25 human oral squamous carcinoma cell line. Cytotoxic effect of ACS extract was determined by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay, using concentrations of 0.1-1000 μg/mL for 24 h. A. catechu ethanol seed extract was treated SCC-25 cells with 25 and 50 μg/mL. At the end of treatment period, apoptotic marker gene expressions such as caspase 8, 9, Bcl-2, Bax, and cytochrome c were evaluated by semiquantitative reverse transcription-polymerase chain reaction. Morphological changes of ACS treated SCC-25 cells was evaluated by acridine orange/ethidium bromide (AO/EB) dual staining. Nuclear morphology and DNA fragmentation was evaluated by propidium iodide (PI) staining. A. catechu ethanol seed extract treatment caused cytotoxicity in SCC-25 cells with an IC 50 value of 100 μg/mL. Apoptotic markers caspases 8 and 9, cytochrome c, Bax gene expressions were significantly increased upon ACS extract treatment indicate the apoptosis induction in SCC-25 cells. This treatment also caused significant downregulation of Bcl-2 gene expression. Staining with AO/EB and PI shows membrane blebbing, and nuclear membrane distortion further confirms the apoptosis induction by ACS treatment in SCC-25 cells. The ethanol seed extracts of A. catechu was found to be cytotoxic at lower concentrations and induced apoptosis in human oral squamous carcinoma SCC-25 cells. Acacia catechu ethanolic seed extract contains phytochemicals such as epicatechin, rutin, and quercetin Acacia catechu seed (ACS) extract significantly ( P < 0.001) inhibits the active proliferation of human oral

    Background Water-pipe smoking is a rapidly growing form of tobacco use worldwide. Building on an earlier report of experimentation with cigarette and water-pipe smoking in a U.S. community sample of Arab-American youth aged 14–18 years, this article examines water-pipe smoking in more detail (e.g., smoking history, belief in harmfulness compared to cigarettes, family members in home who smoke water pipes) and compares the water-pipe–smoking behaviors of Arab-American youth with non–Arab-American youth in the same community. Methods A convenience sample of 1872 Arab-American and non–Arab-American high school students from the Midwest completed a 24-item tobacco survey. Data were collected in 2004–2005 and analyzed in 2007–2008. Results Arab-American youth reported lower percentages of ever cigarette smoking (20% vs 39%); current cigarette smoking (7% vs 22%); and regular cigarette smoking (3% vs 15%) than non–Arab-American youth. In contrast, Arab-American youth reported significantly higher percentages of ever water-pipe smoking (38% vs 21%) and current water-pipe smoking (17% vs 11%) than non–Arab-American youth. Seventy-seven percent perceived water-pipe smoking to be as harmful as or more harmful than cigarette smoking. Logistic regression showed that youth were 11.0 times more likely to be currently smoking cigarettes if they currently smoked water pipes. Youth were also 11.0 times more likely to be current water-pipe smokers if they currently smoked cigarettes. If one or more family members smoked water pipes in the home, youth were 6.3 times more likely to be current water-pipe smokers. The effects of ethnicity were reduced as a result of the explanatory value of family smoking. Conclusions Further research is needed to determine the percentages, patterns, and health risks of water-pipe smoking and its relationship to cigarette smoking among all youth. Additionally, youth tobacco prevention/cessation programs need to focus attention on water

    Approximately 700,000 women in Senegal have suffered female genital mutilation (FGM). Now, following a vote upon legislation banning FGM, public opinion in the country over the practice is more divided than ever. The practitioners of FGM are not taking the law seriously, while politicians hesitate to openly condemn the practice, which still occurs widely in rural zones. Most of the 140 parliamentarians do not believe that laws alone can successfully end FGM in Senegal. Some deputies and feminists believe that several years of sensitization on the issue will be needed to effectively reduce the frequency with which FGM is practiced. Only optimists believe FGM will disappear on its own. The debate threatens to resurface in some areas during the year 2000 presidential election. One deputy from the governing party, originally from southern Senegal, states that he dares not tell his constituency that the president himself created the anti-FGM legislation, especially when locally elected leaders finance villages¿ FGM-related celebrations. According to a scholar of the Koran, FGM is an Islamic practice, but it is not taught in the Koran. FGM is therefore a cultural practice borne from individual choice. In Kolda, 650 km south of Dakar, the practitioners of such mutilation argue that they would rather be imprisoned than abandon the practice they consider to be an immutable component of their cultural history.

    Schistosomiasis is the second most significant parasitic disease in children in several African countries. For this purpose, the "Programme National de Lutte contre les Bilharzioses" (PNLB) was developed in partnership with the World Health Organization (WHO) to control this disease in Senegal. However, geographic isolation of Bedik ethnic groups challenged implementation of the key elements of the schistosomiasis program in eastern Senegal, and therefore, a hospital was established in Ninefescha to improve access to health care as well as laboratory support for this population. The program we have implemented from 2008 in partnership with the PNLB/WHO involved campaigns to 1) evaluate schistosomiasis prevalence in children of 53 villages around Ninefescha hospital, 2) perform a mass drug administration following the protocol established by the PNLB in school-aged children, 3) monitor annual prevalence, 4) implement health education campaigns, and 5) oversee the building of latrines. This campaign led to a drop in schistosomiasis prevalence but highlighted that sustainable schistosomiasis control by praziquantel treatment, awareness of the use of latrines, and inhabitants' voluntary commitment to the program are crucial to improve Schistosoma elimination. Moreover, this study revealed that preschool-aged children, for whom praziquantel was not recommended until 2014 in Senegal, constituted a significant reservoir for the parasite. © The American Society of Tropical Medicine and Hygiene.

    In the past, Acacia tortilis ssp. raddiana (Savi) Brenan colonised thousands of hectares in central and southern Tunisia. Nowadays, the geographical distribution of A. tortilis ssp. raddiana is restricted to the National Park of Bou-Hedma (central Tunisia). The Acacia is of considerable interest for local populations and may be considered as a "foundation species" under arid climate. This study examines the effects of Acacia canopy on soil fertility and cereal productivity. The improvement in soil fertility and microclimate provided by A. tortilis ssp. raddiana is known to facilitate the establishment of new species, but little is known about the interaction between the tree species and the cereals cultivated by local farmers. We studied the effect of A. tortilis ssp. raddiana canopy on the yield of three cereals crops ( Hordeum vulgare L., Triticum sativum L. and Triticum aestivum L.). We seeded 168 plots (15 × 15 m) under the tree canopy and in open areas on four different landform types (glacis, plain, wadis, and jessours) and measured cereal yield over two contrasting years (wet and dry). We found that: (1) precipitation and geomorphology are more important in determining cereal yield than canopy cover, (2) these effects on water availability are species-specific with no effect on the stress-tolerant barley. We finally discuss the potential negative effects of Acacia trees which may have balanced the positive effects found for nutrient in our study.

    The objectives of this study were to: (1) calculate age-specific and age-adjusted cause-specific mortality rates for Arab Americans; and (2) compare these rates with those for blacks and whites. Mortality rates were estimated using Michigan death certificate data, an Arab surname and first name list, and 2000 U.S. Census data. Age-specific rates, age-adjusted all-cause and cause-specific rates were calculated. Arab Americans (75+) had higher mortality rates than whites and blacks. Among men, all-cause and cause-specific mortality rates for Arab Americans were in the range of whites and blacks. However, Arab American men had lower mortality rates from cancer and chronic lower respiratory disease compared to both whites and blacks. Among women, Arab Americans had lower mortality rates from heart disease, cancer, stroke, and diabetes than whites and blacks. Arab Americans are growing in number. Future study should focus on designing rigorous separate analyses for this population.

    At present, the rice syrup as a low price of the sweeteners was often adulterated into acacia honey and the adulterated honeys were sold in honey markets, while there is no suitable and fast method to identify honey adulterated with rice syrup. In this study, Near infrared spectroscopy (NIR) combined with chemometric methods were used to discriminate authenticity of honey. 20 unprocessed acacia honey samples from the different honey producing areas, mixed? with different proportion of rice syrup, were prepared of seven different concentration gradient? including 121 samples. The near infrared spectrum (NIR) instrument and spectrum processing software have been applied in the? spectrum? scanning and data conversion on adulterant samples, respectively. Then it was analyzed by Principal component analysis (PCA) and canonical discriminant analysis methods in order to discriminating adulterated honey. The results showed that after principal components analysis, the first two principal components accounted for 97.23% of total variation, but the regionalism of the score plot of the first two PCs was not obvious, so the canonical discriminant analysis was used to make the further discrimination, all samples had been discriminated correctly, the first two discriminant functions accounted for 91.6% among the six canonical discriminant functions, Then the different concentration of adulterant samples can be discriminated correctly, it illustrate that canonical discriminant analysis method combined with NIR spectroscopy is not only feasible but also practical for rapid and effective discriminate of the rice syrup adulterant of acacia honey.

    Senegal introduced routine infant Haemophilus influenzae type b (Hib) conjugate vaccine during 2005. We evaluated acute bacterial meningitis surveillance data among children 0 to 59 months of age collected during January 2003 to September 2007 at the major pediatric referral hospital in the Dakar Region of Senegal. Hib vaccine effectiveness was assessed using a case-control design. A total of 1749 children with suspected bacterial meningitis were included in the current study of whom 142 (8%) had Hib identified. Among children less than age 1 year, the average annual Hib meningitis incidence decreased from 22 to 47 per 100,000 during 2003-2005 to 1.4 per 100,000 during 2007, while pneumococcal meningitis incidence remained stable. Before vaccine introduction, calculated incidences varied over 4-fold between districts within the Dakar Region for the years 2003 to 2005. Following use of Hib vaccine, pneumococcus has now become the most common etiology of pediatric acute bacterial meningitis in Dakar region. Senegal successfully implemented Hib conjugate vaccine into their routine infant immunization program with a resultant near elimination of Hib meningitis burden.

    Acacia arabica and Moringa oleifera are credited with a number of medicinal properties. Traditionally gum of Acacia plant is used in the treatment of skin disorders to soothe skin rashes, soreness, inflammation and burns while Moringa seed extracts are known to have antibacterial activity. In the present study the potential of the polymeric component of aqueous extracts of gum acacia (GA) and the seeds of M. oleifera (MSP) in wound management was evaluated. The results revealed that both biopolymers were hemostatic and hasten blood coagulation. They showed shortening of activated partial thromboplastin time and prothrombin time and were non-cytotoxic in nature. Both showed antibacterial activity against organisms known to be involved in wound infections with MIC ranging from 500-600 microg mL(-1) for GA and 300-700 microg mL(-1) for MSP. They were biodegradable and exhibited water absorption capacity in the range of 415 to 935%. The hemostatic character coupled to these properties envisions their potential in preparation of dressings for bleeding and profusely exuding wounds. The biopolymers have been further analysed for their composition by Gas chromatography.

    Abortion is highly restricted by law in Senegal. Although women seek care for abortion complications, no national estimate of abortion incidence exists. Data on postabortion care and abortion in Senegal were collected in 2013 using surveys of a nationally representative sample of 168 health facilities that provide postabortion care and of 110 professionals knowledgeable about abortion service provision. Indirect estimation techniques were applied to the data to estimate the incidence of induced abortion in the country. Abortion rates and ratios were calculated for the nation and separately for the Dakar region and the rest of the country. The distribution of pregnancies by planning status and by outcome was estimated. In 2012, an estimated 51,500 induced abortions were performed in Senegal, and 16,700 (32%) resulted in complications that were treated at health facilities. The estimated abortion rate was 17 per 1,000 women aged 15-44 and the abortion ratio was 10 per 100 live births. The rate was higher in Dakar (21 per 1,000) than in the rest of the country (16 per 1,000). Poor women were far more likely to experience abortion complications, and less likely to receive treatment for complications, than nonpoor women. About 31% of pregnancies were unintended, and 24% of unintended pregnancies (8% of all pregnancies) ended in abortion. Unsafe abortion exacts a heavy toll on women in Senegal. Reducing the barriers to effective contraceptive use and ensuring access to postabortion care without the risk of legal consequences may reduce the incidence of and complications from unsafe abortion.

Moreover, we took advantage of the specificity of the Arabic orthographic system, which is characterized by a shallow (i.e., vowelled words) and a deep orthography (i.e., unvowelled words), to examine the relationship between orthographic and semantic processing. Results showed faster Reaction Times (RTs) for semantically related than unrelated words with no difference between vowelled and unvowelled words. By contrast, Event Related Potentials (ERPs) revealed larger N1 and N2 components to vowelled words than unvowelled words suggesting that visual-orthographic complexity taxes the early word processing stages. Moreover, semantically unrelated Arabic words elicited larger N400 components than related words thereby demonstrating N400 effects in Arabic. Finally, the Arabic N400 effect was not influenced by orthographic depth. The implications of these results for understanding the processing of orthographic, semantic, and morphological structures in Modern Standard Arabic are discussed. Copyright © 2014 Elsevier B.V.

    With prevalence of noncommunicable diseases and life expectancy rising in Senegal, the need for palliative care is likely growing. No national palliative care needs assessments have been carried out. To assess the capacity and need for palliative care in Senegal. A multicomponent assessment of availability and demand for palliative care was conducted in two tertiary and two regional hospitals in Senegal in 2015 with approval from Senegal's National Ethics Committee for Health Research. The assessment consisted of (1) an inpatient hospital census; (2, 3) surveys of inpatients and outpatients with life-limiting illness; (4) a knowledge, attitudes, and practices survey among health care workers; and (5) a facility survey to assess availability of palliative care medications. Nearly half (44.4%) of all inpatients (n = 167) had an active life-limiting illness. Among them, 56.6% reported moderate-to-severe pain in the past three days, 2.3% of whom received morphine, and 76.7% received weak or no pain medication. Inpatients also experienced moderate-to-severe dyspnea (42.1%), fatigue (66.5%), nausea (16.5%), and drowsiness (42.1%). About 39.2% of all outpatients (n = 395) reported moderate-to-severe pain, and 52.8% reported that the treatment they had received relieved their pain only partially or not at all. Two-thirds of all doctors reported feeling comfortable prescribing pain medicines; however, 83.0% rarely or never prescribed morphine. Two of four hospitals reported no use of morphine in 2014. There is significant need for palliative care in Senegal. Training of health care workers and ensuring availability of relevant medications should be prioritized.

    This paper presents a brief overview of our research in the development of an OCR system for recognition of machine-printed texts in languages that use the Arabic alphabet. The cursive nature of machine-printed Arabic makes the segmentation of words into letters a challenging problem. In our approach, through a novel preliminary segmentation technique, a word is broken into pieces where each piece may not represent a valid letter in general. Neural networks trained on a training sample set of about 500 Arabic text images are used for recognition of these pieces. The rules governing the alphabet and character-level contextual information are used for recombining these pieces into valid letters. Higher-level contextual analysis schemes including the use of an Arabic lexicon and n-grams is also under development and are expected to improve the word recognition accuracy. The segmentation, recognition, and contextual analysis processes are closely integrated using a feedback scheme. The details of preparation of the training set and some recent results on training of the networks will be presented.

    Australian Acacia are invasive in many parts of the world. Despite significant mechanical and biological efforts to control their invasion and spread, soil-stored seed banks prevent their effective and sustained removal. In response South Africa has had a strong focus on employing seed reducing biological control agents to deal with Australian Acacia invasion, a programme that is considered as being successful. To provide a predictive understanding for their management, seed banks of four invasive Australian acacia species (Acacia longifolia, A. mearnsii, A. pycnantha and A. saligna) were studied in the Western Cape of South Africa. Across six to seven sites for each species, seed bank sizes were estimated from dense, monospecific stands by collecting 30 litter and soil samples. Average estimated seed bank size was large (1017 to 17261 seed m-2) as was annual input into the seed bank, suggesting that these seed banks are not residual but are replenished in size annually. A clear relationship between seed bank size and stem diameter was established indicating that mechanical clearing should be conducted shortly after fire-stimulated recruitment events or within old populations when seed banks are small. In dense, monospecific stands seed-feeding biological control agents are not effective in reducing seed bank size.

    Factor V Leiden (FVL) mutation (G1691A) is a risk factor for development of venous thromboembolic disorders. FVL was found mostly in Caucasians (1-15%) but was almost absent in non-Caucasians. Studies on Arab patients and populations revealed very inconsistent results. This study reports FVL in Arabs living in Kuwait with a focus on the nationality of the Arab subjects studied. Whole-blood samples were collected from 400 healthy Arabs who were 268 Kuwaitis (67%), 50 Syrians (12.5%), 34 Jordanians (8.5%), 8 Palestinians (2%) and 40 Egyptians (10%). DNA extraction was carried out for these blood samples and real-time PCR was performed to detect the presence of FVL. Generally, 36 cases (9%) had the mutation (33 were heterozygous and 3 were homozygous), with an allelic frequency of 0.049. The prevalence of FVL differed in different Arabic cases: Kuwaitis 4.5%, Egyptians 15%, Syrians 16%, Jordanians 23.5% and Palestinians 25%. The allelic frequency was 0.022 in the Kuwaitis and 0.088-0.132 in non-Kuwaitis. The three homozygous cases were from Syria, Jordan and Egypt. In conclusion, the prevalence of FVL in Arabs living in Kuwait is as high as in Caucasians. There is a difference in prevalence among Arabs themselves, being relatively lower in Kuwaitis than in non-Kuwaitis.

    To investigate the psychometric properties (reliability, validity and responsiveness) of the DASH-Arabic in a cohort of Arabic patients presenting with various upper extremity conditions. Participants were 139 patients with various upper extremity conditions, who completed the DASH-Arabic at the baseline, 2-5 days later and 30-36 days later. Participants completed demographic data forms, the SF-36 and VAS at baseline, and a Global Rating of Change scale at first and second follow-ups. Cronbach's alpha of the DASH-Arabic was 0.94. Test-retest reliability was excellent with an ICC of 0.97. The SEM was 3.50 and the MDC95 was 9.28. Construct validity of the DASH-Arabic with the SF-36 subscales and VAS scores ranged from r -0.32 to -0.57, all statistically significant (p < 0.001). The effect size (ES) for the DASH-Arabic was 1.39 and its standard response mean was 1.51. The area under the curve was 0.82 (95% CI = 0.72-0.92, p < 0.001). The optimally efficient cutoff for an improvement was found to be a difference of 15 DASH points. The DASH-Arabic is a reliable, valid and responsive upper extremity outcome measure for patients whose primary language is Arabic; it can be used to document patient status and outcomes and support evidence-based practice. Implications for Rehabilitation The DASH-Arabic demonstrated sound psychometric properties of reliability, validity and responsiveness. It is an effective patient status and outcome tool that will support evidence-based practice. This tool is recommended for evaluating upper extremity work-related injuries and tracking therapeutic outcomes.

    Senegal will be spared by phenomenon of population ageing, which will surely have socioeconomic and cultural consequences that will not be easy to tackle, as all sectors will be affected. In regard to legal protection, there are not any special legal acts for the elderly as is the case for children and women. They are treated just as responsible adults whose legal status is the same as everyone else. As far as the framework of legal protection of elderly people is concerned, Senegal has ratified all international and regional means and mecanisms for the protection of the rights of the elderly. In addition, the authorities have adopted policies and programs that favor taking charge of old people's interests. At the present, Senegal possesses a legal framework for the protection of its elderly people. So the matter is about creating new rights, because even the existing rights are not known to their beneficiaries. What is important is to ensure that the elderly fully enjoy their rights in the same way as the other members of society. It is wise, therefore, to put in place plan for information, public awareness and communication concerning the legal regulating framework. Thus, Senegal could be regarded as a pioneer in terms of the protection the elderly, and these leading programs can represent models for the countries of the region, whose social, sanitary and economic contexts are similar.

    2013-01-01

    In this paper, we present a generic Optical Character Recognition system for Arabic script languages called Nabocr. Nabocr uses OCR approaches specific for Arabic script recognition. Performing recognition on Arabic script text is relatively more difficult than Latin text due to the nature of Arabic script, which is cursive and context sensitive. Moreover, Arabic script has different writing styles that vary in complexity. Nabocr is initially trained to recognize both Urdu Nastaleeq and Arabic Naskh fonts. However, it can be trained by users to be used for other Arabic script languages. We have evaluated our system's performance for both Urdu and Arabic. In order to evaluate Urdu recognition, we have generated a dataset of Urdu text called UPTI (Urdu Printed Text Image Database), which measures different aspects of a recognition system. The performance of our system for Urdu clean text is 91%. For Arabic clean text, the performance is 86%. Moreover, we have compared the performance of our system against Tesseract's newly released Arabic recognition, and the performance of both systems on clean images is almost the same.

  19. Arab tankers move downstream

    DOE Office of Scientific and Technical Information (OSTI.GOV)

    Oppenheim, V.H.

    A second oil embargo is expected to be even more effective than the one of 1973 because heavy Arab investment in tankers gives them greater control over the transportation as well as the supply and price of crude oil. The Organization of Petroleum Exporting Countries (OPEC) nations, having used their surplus capital to buy a tanker fleet, can route oil onto their own ships rather than those of competing companies. Faced with increasing vertical integration of the OPEC nations, the International Energy Authority (IEA) finds its emergency plans for oil sharing threatened. Actual size of the Arab tanker fleet ismore » unknown because of joint ventures and the practice of sailing under flags of convenience, but Saudi Arabia is estimated to have enough ships to carry 50 percent of her oil and Arab control to be about 10 percent of the world tanker capacity. Military action in the event of another embargo is more likely if Arab tankers are present in world sea lanes. Involvement of the major international companies with OPEC allocations divides company loyalties between their suppliers and customers. Joint ventures between Arab oil companies and financial lending institutions are increasing, but could be somewhat balanced if legislation were passed requiring that oil for U.S. markets be transported by secure carriers. The use of surplus tankers as mobile storage units has been proposed as a means of stock-piling oil supplies against a future cutback. (DCK)« less

    2013-01-01

    This paper examines transactional sex in Dakar as a window into broader processes of social and economic change in urban Senegal. Patterns of heterosexual behaviour in Senegal's capital (late and increasing age at first marriage for women, a relatively high divorce rate and a rise in transactional sex) reflect a confluence of socioeconomic forces that curtail some forms of heterosexual union and facilitate others. Our analysis focuses on the rise of mbaraan, a practice in which single, married and divorced women have multiple male partners. We argue that while mbaraan is in part an expression of women's agency and a transgression of dominant gender norms, it also reflects women's social and economic subordination and their inability to achieve self-sufficiency independent of men's financial support. We suggest that this urban phenomenon is the outcome of contradictory opportunities and constraints that women face as they grapple with material insecurity and marital disappointments.

    Precipitation of calcium in plants is common. There are abundant studies on the uptake and content of magnesium, strontium and barium, which have similar chemical properties to calcium, in comparison with those of calcium in plants, but studies on co-precipitation of these elements with calcium in plants are rare. In this study, we compared morphologies, distributional patterns, and elemental compositions of crystals in tissues of four Acacia species grown in the field as well as in the glasshouse. A comparison was also made of field-grown plants and glasshouse-grown plants, and of phyllodes of different ages for each species. Crystals of various morphologies and distributional patterns were observed in the four Acacia species studied. Magnesium, strontium and barium were precipitated together with calcium, mainly in phyllodes of the four Acacia species, and sometimes in branchlets and primary roots. These elements were most likely precipitated in forms of oxalate and sulfate in various tissues, including epidermis, mesophyll, parenchyma, sclerenchyma (fibre cells), pith, pith ray and cortex. In most cases, precipitation of calcium, magnesium, strontium and barium was biologically induced, and elements precipitated differed between soil types, plant species, and tissues within an individual plant; the precipitation was also related to tissue age. Formation of crystals containing these elements might play a role in regulating and detoxifying these elements in plants, and protecting the plants against herbivory.

    An ideal biomaterial for wound dressing applications should possess antibacterial and anti-inflammatory properties without any toxicity to the host cells while providing the maximum healing activity. Zinc oxide nanoparticles (ZnONPs) possess antimicrobial activity and enhance wound healing, but the questions regarding their safety arise before application to the biological systems. We synthesized ZnONPs-loaded-sodium alginate-gum acacia hydrogels (SAGA-ZnONPs) by cross linking hydroxyl groups of the polymers sodium alginate and gum acacia with the aldehyde group of gluteradehyde. Here, we report the wound healing properties of sodium alginate/gum acacia/ZnONPs, circumventing the toxicity of ZnONPs simultaneously. We demonstrated the concentration-dependent zones of inhibition in treated cultures of Pseudomonas aerigunosa and Bacillus cereus and biocompatability on peripheral blood mononuclear/fibroblast cells. SAGA-ZnONPs hydrogels showed a healing effect at a low concentration of ZnONPs using sheep fibroblast cells. Our findings suggest that high concentrations of ZnONPs were toxic to cells but SAGA-ZnONPs hydrogels significantly reduced the toxicity and preserved the beneficial antibacterial and healing effect.

    The potential of scattered trees as keystone structures in restoring degraded environments is gaining importance. Scattered trees have strong influence on their abiotic environment, mainly causing changes in microclimate, water budget and soil properties. They often function as 'nursing trees', facilitating the recruitment of other plants. Acacia raddiana is such a keystone species which persists on the edge of the Sahara desert. The study was conducted in a forest-steppe ecosystem in central Tunisia where several reforestation campaigns with Acacia took place. To indentify the impact of those trees on soil nutrients, changes in nutrient levels under scattered trees of three age stages were examined for the upper soil layer (0-10 cm) at five microsites with increasing distance from the trunk. In addition, changes in soil nutrient levels with depth underneath and outside the canopy were determined for the 0-30 cm soil layer. Higher concentrations of organic matter (OM) were found along the gradient from underneath to outside the canopy for large trees compared to medium and small trees, especially at microsites close to the trunk. Levels of soluble K, electrical conductivity (EC), available P, OM, total C and N decreased whereas pH and levels of soluble Mg increased with increasing distance from tree. Levels of soluble Ca and Na remained unchanged along the gradient. At the microsite closest to the trunk a significant decrease in levels of soluble K, EC, OM, available P, total C and N, while a significant increase in pH was found with increasing depth. The concentration of other nutrients remained unchanged or declined not differently underneath compared to outside the canopy with increasing depth. Differences in nutrient levels were largely driven by greater inputs of organic matter under trees. Hence, Acacia trees can affect the productivity and reproduction of understory species with the latter in term an important source of organic matter. This positive feedback

    Consumer preferences in east Asian part of the world pave the way for consumption of lotus stem starch (LSS) in preparations such as breakfast meals, fast foods, and traditional confectioneries. The present study envisaged the investigation and optimization of additives, that is, acacia gum, sodium chloride (NaCl), and sucrose, on water absorption (WA), water absorption index (WAI), and water solubility index (WSI) of LSS employing response surface methodology (RSM). Acacia gum resulted in increased water uptake and swelling of starch; however, NaCl reduced the swelling power of starch by making water unavailable to starch and also due to starch-ion electrostatic interaction. Sucrose restricted the water absorption by binding free water and decreased amylose leaching by building bridges with starch chains and thus forming rigid structure. PMID:26904639

    An assessment was made as to whether maternal residence in areas with high Arab-American concentrations, hence with expected low acculturation for this ethnic group, was associated with low-birth-weight (<2500 g) (LBW) risk among Arab-ethnicity mothers (AEM). Data on all births in Michigan from 2000 to 2005 were collected. Bivariate chi(2) tests and multivariable logistic regression models were used to assess the relation between residence in areas with a high Arab-American concentration and risk for LBW among AEM. As a control, analyses were replicated among non-Arab white mothers. Both residence in Dearborn (OR=0.85, 95% CI 0.75 to 0.97), the city with the highest Arab-American concentration in the USA, and residence in 48126 (OR=0.81, 95% CI 0.71 to 0.93), the zip code with the highest concentration of AEM in Dearborn, were associated with a lower risk for LBW compared with residence in the rest of Michigan in multivariable models adjusted for potential confounders. Neither residence in Dearborn nor residence in 48126 was associated with LBW risk among non-Arab white mothers. Residence in areas with high Arab-American concentrations was associated with a lower LBW risk among AEM. Future work should directly measure acculturation, a plausible mediator of this observed relation.

    2001-01-01

    When the Arabic-Islamic medicine evolved partly as a consequence of the wave of translations from mainly Greek medical books to Arabic in the 9th century the pharmacological works, which were available, were also translated. The books of Dioscurides and Galen on pharmacological matters became the decisive books of pharmacological translated literature and they formed the basis of the pharmacological understanding in the subsequent extensive literature on pharmacognosy and pharmacology written in Arabic. Nevertheless the Arabs united these two disciplines in a regular pharmacy and they evolved it as an independent discipline, which although attached to medicine was regarded as having its own praxis. The physicians and scientists rationalized and systematized their knowledge of medicinal plants and drugs and extended their knowledge by using original observations and research. Many books on medicaments were written, both as materia medica, i.e. records on simple drugs, and dispensatories, i.e. books on compounded drugs. These two kinds of books were always written separately as they were seen by the Arabs themselves as pertaining to two different subdisciplines, which meant that they were separated too in independent chapters or books in general Arabic works on medicine. When the extensive translations of Arabic medical literature to Latin took place in Italy and Spain in the 11th and 12th centuries, the Arabic pharmacological literature was of course also translated, and its decisive influence on later medieval European medical writings is easy to demonstrate. In the 18th century Peter Forsskaal was one of the first Europeans in the modern scientific tradition to collect and make notes on drugs used in Cairo and in Yemen.

    Exploring the presence and role of human papillomavirus (HPV) in head and neck cancer (HNC) is a necessary step to evaluate the potential impact of HPV prophylactic vaccines. To assess the prevalence and oncogenic role of HPV in HNC in Senegal. This is a multicenter cross-sectional study. Paraffin-embedded blocks of cases diagnosed with invasive HNC between 2002 and 2010 were collected from 4 pathology laboratories in Senegal. Presence of HPV DNA was determined by PCR and DEIA, and genotyping performed with LiPA25. Tubulin analysis was performed to assess DNA quality. HPV DNA-positive cases were tested for p16INK4a expression. A total of 117 cases were included in the analysis: 71% were men, mean age was 52 years old (SD ±18.3), and 96% of cases were squamous cell carcinoma. Analysis was performed on 41 oral cavity tumors, 64 laryngeal tumors, 5 oropharyngeal tumors and 7 pharyngeal tumors. Only four cases (3.4%; 95% CI = 0.9%-8.5%) harbored HPV DNA. HPV types detected were HPV16, HPV35 and HPV45. However, among HPV-positive cases, none showed p16INK4a overexpression. Our findings indicate that HPV DNA prevalence in HNC in Senegal is very low, suggesting that HPV is not a strong risk factor for these cancers. Additional larger studies are needed to confirm these findings and explore other potential risk factors specific to the region.

    Schistosomiasis is a highly prevalent parasitic disease in Senegal. The early symptoms are hematuria and dysuria. Children's comprehension of the disease is fundamental to preventing the infection. The aim of this study was to investigate the knowledge attitudes, and practices related to schistosomiasis among schoolchildren in 2 rural villages in Northern Senegal and to evaluate their impact on the disease. A cross-sectional study was conducted. Data about children's knowledge of schistosomiasis, behavior, and preventive measures were collected through a questionnaire. Questionnaire responses from 575 schoolchildren were analyzed. Correct answers about risky behavior for schistosomiasis were associated with early symptoms (P = 0.010). Wearing shoes and washing hands with soap were associated with not having hematuria and dysuria (P = 0.007 and 0.049, respectively). Playing in rivers was associated with the aforementioned symptoms (P < 0.001). Children who had good knowledge of schistosomiasis reportedly did not have symptoms (P = 0.002). A logistic regression model showed that female sex (odds ratio = 0.35; P = 0.01) and attending a primary school (odds ratio = 0.13; P < 0.001) were significant predictors of a lower risk of the early symptoms of urinary schistosomiasis. This study revealed that the level of knowledge among children in North Senegal about the causes, transmission, prevention, and treatment of schistosomiasis warrants implementing educational intervention.

    The aim of the current study was to address a gap in the literature by determining prevalence, specific types of violence, and risk factors of intimate partner violence (IPV) among Israeli born Arab women compared with Israeli born Jewish women. The following measures were compared: demographic and socioeconomic measures; measures relating to the characteristics of the violence, that is, the three types of violence (physical, emotional, and verbally threatening), sense of danger, and history of violence in childhood; family support levels; and perpetrator characteristics. The sample consisted of 154 Israeli born Arab women and 149 Israeli born Jewish women who were staying in shelters for victims of domestic violence in Israel. A comparison of the two groups revealed that the Arab women were exposed to more physical violence and received less family support than did their Jewish counterparts. The proportion of Arab perpetrators with access to weapons was higher than that of Jewish perpetrators, whereas the proportion of police complaints against Jewish perpetrators was higher than that against Arab perpetrators. Arab women were also younger, less educated, and less a part of the workforce than Jewish women. The contribution of the woman's age to the variance in levels of physical violence was negative and significant. In contrast, the contribution of her sense of danger, and various perpetrator characteristics, was positive. Moreover, the interaction between sense of danger × ethnicity contributed significantly to levels of violence. This study extends the existing knowledge about the contribution of ethnicity as one of many variables that play a role in the lives of women who are victims of domestic violence and highlights the need to develop, in particular, unique individual, community, and social interventions for Arab women in Israeli society.

  17. Vision, touch and object manipulation in Senegal parrots Poicephalus senegalus

    Parrots are exceptional among birds for their high levels of exploratory behaviour and manipulatory abilities. It has been argued that foraging method is the prime determinant of a bird's visual field configuration. However, here we argue that the topography of visual fields in parrots is related to their playful dexterity, unique anatomy and particularly the tactile information that is gained through their bill tip organ during object manipulation. We measured the visual fields of Senegal parrots Poicephalus senegalus using the ophthalmoscopic reflex technique and also report some preliminary observations on the bill tip organ in this species. We found that the visual fields of Senegal parrots are unlike those described hitherto in any other bird species, with both a relatively broad frontal binocular field and a near comprehensive field of view around the head. The behavioural implications are discussed and we consider how extractive foraging and object exploration, mediated in part by tactile cues from the bill, has led to the absence of visual coverage of the region below the bill in favour of more comprehensive visual coverage above the head.

  18. Vegetation impoverishment despite greening: a case study from central Senegal

    2013-01-01

    Recent remote sensing studies have documented a greening trend in the semi-arid Sahel and Sudan zones of West Africa since the early 1980s, which challenges the mainstream paradigm of irreversible land degradation in this region. What the greening trend means on the ground, however, has not yet been explored. This research focuses on a region in central Senegal to examine changes in woody vegetation abundance and composition in selected sites by means of a botanical inventory of woody vegetation species, repeat photography, and perceptions of local land users. Despite the greening, an impoverishment of the woody vegetation cover was observed in the studied sites, indicated by an overall reduction in woody species richness, a loss of large trees, an increasing dominance of shrubs, and a shift towards more arid-tolerant, Sahelian species since 1983. Thus, interpretation of the satellite-derived greening trend as an improvement or recovery is not always justified. The case of central Senegal represents only one of several possible pathways of greening throughout the region, all of which result in similar satellite-derived greening signals.

  19. Rapid evolution of water resources in the Senegal delta

    In recent decades major water developments have led to an agricultural transformation of the Senegal delta both in Senegal and Mauritania. This otherwise, semi-arid region of the Sahel band now has an abundant supply of freshwater all year round mostly used for irrigation and urban water supply, including for the capital cities of the two countries. Archives from the Landsat satellites and in-situ hydrographs were used in this paper to retrace and analyse the hydrological changes that have taken place in the region since the middle of the 20th century. The satellite archives indicate that the area covered by irrigation increased by one order of magnitude from 73 km2 in 1973 to 770 km2 in 2010. The observed hydrological changes are complex, multi-faceted and often of great magnitude. If the water cycle was representative of natural conditions in the early 1980s, it is now representative of a heavily modified system controlled and impacted by human activities. The first hydraulic infrastructure was installed in 1947 to enable the Lake of Guiers to become the main water supply for Dakar. Two large dams were built on the Senegal River in the mid-1980s that modified the hydrological regime of the river by 1) preventing seawater intrusion, 2) raising the stage of the river and of Lake of Guiers and 3) moderating floods. Another recent hydrological change in the delta was the opening of river mouth in 2003, which has led to a reduction of the average water level while increasing the semi-diurnal tidal wave between the river mouth and Diama. Each phase of these river regime changes and each step of the irrigation expansion are expressed in localised changes in the physical groundwater system. Increasingly, the retroaction from the shallow aquifer systems is observed as a rise of the saline water table. This poses a threat to the environmental and agricultural value of the region, and the salinization of the soils. Mitigating actions for this threat are currently being

    In Senegal, recent data indicates that the HIV epidemic is increasingly driven by concurrent sexual partners among men and women in stable relationships. In order to respond to this changing epidemiological profile in Senegal, multi-lateral and national AIDS actors require information about these emerging trends in unstudied populations. To that end, this study has several objectives, first, to assess local dynamics of sexual behaviors among individuals at popular socializing venues in areas at increased risk of HIV transmission; and then to examine how particular venues may influence risks of HIV transmission. In 2013 we collected data at 314 venues in 10 cities in Senegal using PLACE methodology. These venues were listed with collaboration of 374 community informants. They are places where commercial sex workers, MSM, and individuals who are not part of any identified risk group socialize and meet new sexual partners. We conducted 2600 interviews at the 96 most popular venues. A significant portion of the sample reports buying or selling sex and the majority engaged in behavior considered high-risk for transmitting sexual infections. Almost a quarter of patrons interviewed in venues were young people aged 15-24 years. Types of venues described were very diverse. Half of them were venues (n = 156) where sex workers could be solicited and almost a third were venues where MSM could meet male partners (n = 90). The study showed existing pockets of vulnerability to HIV in Thies, Bignona or Saly that are not evident from aggregate HIV data. These early findings suggest links between risky behaviors and type of venue on the one hand and type of city on the other hand. Finally, these findings offer complementary insight to existing studies of HIV vulnerability in Senegal and support a case for venue-based interventions. Copyright © 2014 Elsevier Ltd.

    Genetic disorders are not equally distributed over the geography of the Arab region. While a number of disorders have a wide geographical presence encompassing 10 or more Arab countries, almost half of these disorders occur in a single Arab country or population. Nearly, one-third of the genetic disorders in Arabs result from congenital malformations and chromosomal abnormalities, which are also responsible for a significant proportion of neonatal and perinatal deaths in Arab populations. Strikingly, about two-thirds of these diseases in Arab patients follow an autosomal recessive mode of inheritance. High fertility rates together with increased consanguineous marriages, generally noticed in Arab populations, tend to increase the rates of genetic and congenital abnormalities. Many of the nearly 500 genes studied in Arab people revealed striking spectra of heterogeneity with many novel and rare mutations causing large arrays of clinical outcomes. In this review we provided an overview of Arab gene geography, and various genetic abnormalities in Arab populations, including disorders of blood, metabolic, circulatory and neoplasm, and also discussed their associated molecules or genes responsible for the cause of these disorders. Although studying Arab-specific genetic disorders resulted in a high value knowledge base, approximately 35% of genetic diseases in Arabs do not have a defined molecular etiology. This is a clear indication that comprehensive research is required in this area to understand the molecular pathologies causing diseases in Arab populations. PMID:25780794

    To explore the healthcare needs of older Arab migrants, focussing on Arab-Australians and their socio-cultural characteristics. Disparities in accessing healthcare services and addressing healthcare needs are evident among ethnic minorities including Arab migrants, particularly, older people. Racial stereotyping can also affect their ability to use these services. Arabs are a populous and diverse group with a long history of global migration. Australia is one of the most multicultural societies in the world, and Arab-Australians constitute an important ethnic minority group. Systematic review. The electronic databases Academic Search Complete (EBSCO), MEDLINE (Ovid), Ageline, ProQuest, CINAHL, PubMed, PsychINFO and Google Scholar were searched from 1990-October 2012. Search terms included health care needs, aged care, ethnic, cultural, linguistics, social, ethnic groups, culturally and linguistically diverse, nonEnglish speaking, ageing, elderly, Arabs, Arabic-speaking and Australia. Eight articles reviewing the healthcare issues of Australians from Arabic-speaking background were identified using the search strategy. An additional eight articles were identified through hand searching. Racial stereotyping can alter health-seeking behaviours and healthcare treatment. Increasing the understanding of specific cultural attributes of Arab-Australians will contribute to improving health outcomes. Healthcare providers and policymakers need to adopt more effective ways of communication with Arab-Australians to provide more culturally competent care and achieve better health outcomes. © 2013 John Wiley & Sons Ltd.

    The biological invasion of Australian Acacia species in natural ecosystems outside Australia has often a negative impact on native and endemic plant species and the related biodiversity. In Brazil, the Atlantic rainforest of Bahia and Espirito Santo forms an associated type of ecosystem, the Mussununga. In our days this biologically diverse ecosystem is negatively affected by the invasion of Acacia mangium and Acacia auriculiformis, both introduced to Brazil by the agroforestry to increase the production of pulp and high grade woods. In order to detect the distribution of Acacia species and to monitor the expansion of this invasion the use of high-resolution imagery data acquired with an autonomous Unmanned Aerial System (UAS) proved to be a very promising approach. In this study, two types of datasets - CIR and RGB - were collected since both types provide different information. In case of CIR imagery attention was paid on spectral signatures related to plants, whereas in case of RGB imagery the focus was on surface characteristics. Orthophoto-mosaics and DSM/DTM for both dataset were extracted. RGB/IHS transformations of the imagery's colour space were utilized, as well as NDVIblue index in case of CIR imagery to discriminate plant associations. Next, two test areas were defined in order validate OBIA rule sets using eCognition software. In case of RGB dataset, a rule set based on elevation distinction between high vegetation (including Acacia) and low vegetation (including soils) was developed. High vegetation was classified using Nearest Neighbour algorithm while working with the CIR dataset. The IHS information was used to mask shadows, soils and low vegetation. Further Nearest Neighbour classification was used for distinction between Acacia and other high vegetation types. Finally an accuracy assessment was performed using a confusion matrix. One can state that the IHS information appeared to be helpful in Acacia detection while the surface elevation

    To assess the progression of mental health research over four decades in the Arab world. Publications on mental health in 21 Arab countries from 1966 to 2006 were screened using PubMed and Psychinfo. Data were collected and analyzed for Arab authors and affiliations, publication year, topic and type of journal. In 40 years (1966-2005), the Arab world published 2,213 articles on a vast variety of topics, most common being mood, anxiety and substance use disorders, and mostly in international journals. By the last decade, the total yearly publications increased about eightfold since the first two decades, and nearly doubled from the third one. The disparity of output was high across countries. The highest yearly output was from Egypt, Saudi Arabia, Kuwait and Lebanon. Per million population, the top four producing countries were Kuwait, Bahrain, Lebanon and United Arab Emirates. Over a decade, the Arab world produced approximately 17% of the global output of mental health publications/million population and was comparative to Latin American and Caribbean countries. There is a wide gap in comparison with the industrialized world, with a fertile ground for cross-cultural and genetic studies.

    Background. Gum arabic is a potential sensitizer in food industry. Methods. We examined 11 candy factory workers referred to examinations due to respiratory and skin symptoms paying attention to exposure and sensitization to gum arabic. Skin tests, pulmonary function tests, and respiratory provocation tests were carried out as indicated by the symptoms and findings. Results. Occupational asthma, caused by gum arabic was diagnosed in 4/11 candy factory workers and two of them had also occupational contact urticaria and one had occupational rhinitis. One of them had oral symptoms associated with ingestion of products containing gum arabic. Conclusions. Airborne exposure to gum arabic may cause sensitization leading to allergic rhinitis, asthma, and urticaria. PMID:21747872

    The Arabs comprise a genetically heterogeneous group that resulted from the admixture of different populations throughout history. They share many common characteristics responsible for a considerable proportion of perinatal and neonatal mortalities. To this end, the Centre for Arab Genomic Studies (CAGS) launched a pilot project to construct the 'Catalogue of Transmission Genetics in Arabs' (CTGA) database for genetic disorders in Arabs. Information in CTGA is drawn from published research and mined hospital records. The database offers web-based basic and advanced search approaches. In either case, the final search result is a detailed HTML record that includes text-, URL- and graphic-based fields. At present, CTGA hosts entries for 692 phenotypes and 235 related genes described in Arab individuals. Of these, 213 phenotypic descriptions and 22 related genes were observed in the Arab population of the United Arab Emirates (UAE). These results emphasize the role of CTGA as an essential tool to promote scientific research on genetic disorders in the region. The priority of CTGA is to provide timely information on the occurrence of genetic disorders in Arab individuals. It is anticipated that data from Arab countries other than the UAE will be exhaustively searched and incorporated in CTGA (http://www.cags.org.ae).

    Population policies are currently at the center of debates about demography and development, and are a preoccupation of most governments, international organizations, and research institutions working in the areas of population, development, and human resources. Between 1988-93, 4 Sahel countries adopted populations policies. this article compares the policies of Senegal, Mali, and Burkina Faso. The 3 policy documents have similar structures, with preambles recalling the international agreements concerning population and development entered into by their governments. A chapter on population and development describes the demo-economic problem in each country at regional, sectorial, and global levels. After the analysis of demo-economic problems, each of the 3 has a chapter presenting the population policy. Each presentation covers the foundations and basic principles of the policy, its objectives, the strategies to be pursued, and the organizational structure. Development of each policy was technically supervised by the Planning Ministry in collaboration with the national population councils. In general terms, the 3 countries recognize in their basic principles that the population is the primary source of wealth of a nation. Each country states its desire to translate the recommendations of different African and world population conferences into concrete acts. The principles avow respect for fundamental human rights including the right to informed decision making by couples on number and spacing of children. The principles also recognize the need for an integrated approach to population and development. The ultimate objective of the population policies is improvement in the standard and quality of life. The number of general objectives outlined in the policies varied from 7 in Senegal to 13 in Burkina Faso. Senegal was the only country of the 3 to specify reduction of the fertility rate and the growth rate as an objective. Senegal and Burkina Faso included

    Eucalyptus spp. is a dominant tree genus in Australia and most Eucalyptus spp. are canopy dominant species. In Australian natural forests, Eucalyptus spp. commonly are associated with understorey legumes which play a crucial role for ecological restoration owing to their nitrogen (N) fixing ability for replenishing the soil N lost after frequent prescribed burning. This study aimed to explore to what extent physiological responses of these species differ 7 and 12 years after last fire. Two most common understorey Acacia spp., Acacia leiocalyx and A. disparrima, as well as one non-leguminous Eucalyptus resinifera, were studied due to their dominance in the forest. Both A. leiocalyx and A. disparrima showed higher carbon (C) assimilation capacity, maximum photosynthetic capacity, and moderate foliar C/N ratio compared with E. resinifera. A. leiocalyx showed various advantages compared to A. disparrima such as higher photosynthetic capacity, adaptation to wider light range and higher foliar total N (TNmass). A. leiocalyx also relied on N2-fixing ability for longer time compared to A. disparrima. The results suggested that the two Acacia spp. were more beneficial to C and N cycles for the post burning ecosystem than the non-N2-fixing species E. resinifera. A. leiocalyx had greater contribution to complementing soil N cycle long after burning compared to A. disparrima.

    Distinct functional pathways for processing words and numbers have been hypothesized from the observation of dissociated impairments of these categories in brain-damaged patients. We aimed to identify the cortical areas involved in Arabic number reading process in patients operated on for various brain lesions. Direct cortical electrostimulation was prospectively used in 60 brain mappings. We used object naming and two reading tasks: alphabetic script (sentences and number words) and Arabic number reading. Cortical areas involved in Arabic number reading were identified according to location, type of interference, and distinctness from areas associated with other language tasks. Arabic number reading was sustained by small cortical areas, often extremely well localized (<1 cm(2)). Over 259 language sites detected, 43 (17%) were exclusively involved in Arabic number reading (no sentence or word number reading interference detected in these sites). Specific Arabic number reading interferences were mainly found in three regions: the Broca area (Brodmann area 45), the anterior part of the dominant supramarginal gyrus (Brodmann area 40; p < 0.0001), and the temporal-basal area (Brodmann area 37; p < 0.05). Diverse types of interferences were observed (reading arrest, phonemic or semantic paraphasia). Error patterns were fairly similar across temporal, parietal, and frontal stimulation sites, except for phonemic paraphasias, which were found only in supramarginal gyrus. Our findings strongly support the fact that the acquisition through education of specific symbolic entities, such as Arabic numbers, could result in the segregation and the specialization of anatomically distinct brain areas.

    (13)C NMR is an effective method of characterizing proanthocyanidin (PAC) tannins in quebracho (Schinopsis lorentzii) heartwood and black wattle (Acacia mearnsii) bark, before and after commercial extraction. The B-rings of the constituent flavan-3-ols, catechols (quebracho) or pyrogallols (wattle), are recognized in unprocessed source materials by "marker" signals at ca. 118 or 105ppm, respectively. NMR allows the minimum extraction efficiency to be calculated; ca. 30%, and ca. 80%, for quebracho heartwood and black wattle bark, respectively. NMR can also identify PAC tannin (predominantly robinetinidin), and compare tannin content, in bark from other acacia species; tannin content decreases in the order A. mearnsii, Acacia pycnantha (87% of A. mearnsii), Acacia dealbata and Acacia decurrens (each 74%) and Acacia karroo (30%). Heartwood from an underexploited PAC tannin source, Searsia lancea, taxonomically close to quebracho, shows abundant profisetinidin and catechin PACs. NMR offers the advantage of being applicable to source materials in their native state, and has potential applications in optimizing extraction processes, identification of tannin sources, and characterization of tannin content in cultivar yield improvement programmes.

    2015-01-01

    Economic growth and modernization of society are generally associated with fertility rate decreases but which forces trigger this is unclear. In this paper we assess how fertility changes with increased labor market participation of women in rural Senegal. Evidence from high-income countries suggests that higher female employment rates lead to reduced fertility rates but evidence from developing countries at an early stage of demographic transition is largely absent. We concentrate on a rural area in northern Senegal where a recent boom in horticultural exports has been associated with a sudden increase in female off-farm employment. Using survey data we show that employed women have a significantly higher age at marriage and at first childbirth, and significantly fewer children. As causal identification strategy we use instrumental variable and difference-in-differences estimations, combined with propensity score matching. We find that female employment reduces the number of children per woman by 25%, and that this fertility-reducing effect is as large for poor as for non-poor women and larger for illiterate than for literate women. Results imply that female employment is a strong instrument for empowering rural women, reducing fertility rates and accelerating the demographic transition in poor countries. The effectiveness of family planning programs can increase if targeted to areas where female employment is increasing or to female employees directly because of a higher likelihood to reach women with low-fertility preferences. Our results show that changes in fertility preferences not necessarily result from a cultural evolution but can also be driven by sudden and individual changes in economic opportunities.

  4. Biomedical science journals in the Arab world.

    PubMed

    Tadmouri, Ghazi O

    2004-10-01

    Medieval Arab scientists established the basis of medical practice and gave important attention to the publication of scientific results. At present, modern scientific publishing in the Arab world is in its developmental stage. Arab biomedical journals are less than 300, most of which are published in Egypt, Lebanon, and the Kingdom of Saudi Arabia. Yet, many of these journals do not have on-line access or are indexed in major bibliographic databases. The majority of indexed journals, however, do not have a stable presence in the popular PubMed database and their indexes are discontinued since 2001. The exposure of Arab biomedical journals in international indices undoubtedly plays an important role in improving the scientific quality of these journals. The successful examples discussed in this review encourage us to call for the formation of a consortium of Arab biomedical journal publishers to assist in redressing the balance of the region from biomedical data consumption to data production.

    Natour, Yaser S; Wingate, Judith M

    2009-09-01

    This study is the first in a series of investigations designed to test the acoustic characteristics of the normal Arabic voice. The subjects were three hundred normal Jordanian Arabic speakers (100 adult males, 100 adult females, and 100 children). The subjects produced a sustained phonation of the vowel /a:/ and stated their complete names (i.e. first, second, third and surname) using a carrier phrase. The samples were analyzed using the Multi Dimensional Voice Program (MDVP). Fundamental frequency (F0) from the /a:/ and speaking fundamental frequency (SF0) from the sentence were analyzed. Results revealed a significant difference of both F0 and SF0 values among adult Jordanian Arabic-speaking males (F0=131.34Hz +/- 18.65, SF0=137.45 +/- 18.93), females (F0=231.13Hz +/- 20.86, SF0=230.84 +/- 16.50) and children (F0=270.93Hz +/- 20.01, SF0=278.04 +/- 32.07). Comparison with other ethnicities indicated that F0 values of adult Jordanian Arabic-speaking males and females are generally consistent with adult Caucasian and African-American values. However, for Jordanian Arabic-speaking children, a higher trend in F0 values was present than their Western counterparts. SF0 values for adult Jordanian Arabic-speaking males are generally consistent with the adult Caucasian male SF0 values. However, SF0 values of adult Jordanian-speaking females and children were relatively higher than the reported Western values. It is recommended that speech-language pathologists in Arabic-speaking countries, Jordan in specific, utilize the new data provided (F0 and SF0) when evaluating and/or treating Arabic-speaking patients. Due to its cross-linguistic variability, SF0 emerged as a preferred measurement when conducting cross-cultural comparisons of voice features.

    2015-09-01

    In this work, gum acacia (GA)/poly(sodium acrylate) semi-interpenetrating polymer networks (Semi-IPN) have been fabricated via free radical initiated aqueous polymerization of monomer sodium acrylate (SA) in the presence of dissolved Gum acacia (GA), using N,N'-methylenebisacrylamide (MB) as cross-linker and potassium persulphate (KPS) as initiator. The semi-IPNs, synthesized, were characterized by various techniques such as X-ray diffraction (XRD), thermo gravimetric analysis (TGA) and Fourier transform infrared (FTIR) spectroscopy. The dynamic water uptake behavior of semi-IPNs was investigated and the data were interpreted by various kinetic models. The equilibrium swelling data were used to evaluate various network parameters. The semi-IPNs were used as template for the in situ preparation of silver nanoparticles using extract of Syzygium aromaticum (clove). The formation of silver nanoparticles was confirmed by surface plasmon resonance (SPR), XRD and transmission electron microscopy (TEM). Finally, the antibacterial activity of GA/poly(SA)/silver nanocomposites was tested against E. coli. Copyright © 2015 Elsevier B.V. All rights reserved.

    This study aimed to estimate the evolution of the maternal and neonatal tetanus in Senegal from the tetanus vaccination coverage among pregnant women, the proportion of deliveries attended by trained medical personnel and the number of cases of tetanus declared by respective districts, helping to identify districts at high risk of neonatal tetanus (NNT). Data analysis of the epidemiological surveillance realized from 2003 to 2009 in 65 districts of Senegal. Data were collected from the reports of vaccination usage and from the Statistical Directories of the National Health Information Services of the Ministry of Health & Prevention. A district is at high risk when the incidence of NNT is ≥1 case per 1 000 Live births (LB). There were 153 reported cases of NNT in Senegal between 2003 and 2009. National incidence decreased from 0.08 to 0.03 case per 1 000 LB (p = 0,0008). The vaccination coverage of the pregnant women by at least two doses of tetanus vaccine (VAT2+) increased from 66% in 2003 to 78% in 2009. The percentage of districts that had reached a vaccination coverage ≥80% was 20% in 2003 compared to 60% in 2009 (p = 0.009). The proportion of deliveries attended by qualified medical staff evolved from 53% in 2003 to 67% in 2009 (p = 0,02). By 2009, the incidence of NNT was less than 1 case per 1,000 LBs in all districts. Assessing the elimination of maternal and neonatal tetanus in Senegal shows that progress has been made from 2003 to 2009. This was made possible through the organization of vaccination campaigns for women of childbearing age and the improvements in the conditions of deliveries.

  13. Politics, gender and youth citizenship in Senegal: Youth policing of dissent and diversity

    Crossouard, Barbara; Dunne, Máiréad

    2015-02-01

    This paper reports on empirical research on youth as active citizens in Senegal with specific reference to their education and their sexual and reproductive health rights. In a context of postcoloniality which claims to have privileged secular, republican understandings of the constitution, the authors seek to illuminate how youth activists sustain patriarchal, metropolitan views of citizenship and reinforce ethnic and locational (urban/rural) hierarchies. Their analysis is based on a case study of active youth citizenship, as reflected in youth engagement in the recent presidential elections in Senegal. This included involvement in youth protests against pre-election constitutional abuse and in a project monitoring the subsequent elections using digital technologies. The authors compare how youth activists enacted different notions of citizenship, in some instances involving a vigorous defence of Senegal's democratic constitution, while in others dismissing this as being irrelevant to youth concerns. Here the authors make an analytic distinction between youth engagement in politics, seen as the public sphere of constitutional democracy, and the political, which they relate to the inherently conflictual and agonistic processes through which (youth) identities are policed, in ways which may legitimate or marginalise. Despite the frequent construction of youth as being agents of change, this analysis shows how potentially productive and open spaces for active citizenship were drawn towards conformity and the reproduction of existing hegemonies, in particular through patriarchal gender relations and sexual norms within which female youth remained particularly vulnerable.

    After 8 years of silence, dengue virus serotype 2 (DENV-2) reemerged in southeastern Senegal in 1999. Sixty-four DENV-2 strains were isolated in 1999 and 9 strains in 2000 from mosquitoes captured in the forest gallery and surrounding villages. Isolates were obtained from previously described vectors, Aedes furcifer, Ae. taylori, Ae. luteocephalus, and--for the first time in Senegal--from Ae. aegypti and Ae. vittatus. A retrospective analysis of sylvatic DENV-2 outbreaks in Senegal during the last 28 years of entomologic investigations shows that amplifications are periodic, with intervening, silent intervals of 5-8 years. No correlation was found between sylvatic DENV-2 emergence and rainfall amount. For sylvatic DENV-2 vectors, rainfall seems to particularly affect virus amplification that occurs at the end of the rainy season, from October to November. Data obtained from investigation of preimaginal (i.e., nonadult) mosquitoes suggest a secondary transmission cycle involving mosquitoes other than those identified previously as vectors.

    Arab ethnicity (AE) mothers have lower preterm birth (PTB) risk than white mothers. Little is known about the determinants of PTB among AE women or the role of interethnic mating in shaping PTB risk among this group. We assessed the relationship between interethnic mating and risk for PTB, very PTB, and late PTB among AE mothers. Data was collected for all births (N = 21,621) to AE women in Michigan between 2000 and 2005. Self-reported ancestry was used to determine paternal AE as well as to identify AE mothers. We used bivariate chi-square tests and multivariable logistic regression to assess the relationship between paternal non-AE and risk for PTB, very PTB, and late PTB among AE mothers. All analyses were also conducted among non-Arab white mothers as a control. Among AE mothers, paternal non-Arab ethnicity was associated with higher risk of PTB (OR = 1.18, 95% CI = 1.06, 1.30) and late PTB (OR = 1.24, 95% CI = 1.20, 1.38) compared to paternal Arab ethnicity. Paternal non-Arab ethnicity was not associated with risk for any outcome among non-Arab white mothers. Future studies could assess the causal mechanisms underlying the association between interethnic mating and risk for PTB. PMID:21042936

    This selective review describes recent literature and the author's experience with mental illness and mental health care, and the impact of cultural transformation on mental health in some Arab Islamic cultures, particularly in Egypt, Qatar and Kuwait. Traditional extended Arab families provide a structure for their members that may sometimes prevent and or compensate for the effects of parental loss and mental disability. The role of traditional families in the care of members and in medical decision-making is discussed. The impact of cultural change on Arab culture is also examined, as is the effect of intergenerational conflict in traditional families.

    Consanguineous marriages have been practiced since the early existence of modern humans. Until now consanguinity is widely practiced in several global communities with variable rates depending on religion, culture, and geography. Arab populations have a long tradition of consanguinity due to socio-cultural factors. Many Arab countries display some of the highest rates of consanguineous marriages in the world, and specifically first cousin marriages which may reach 25-30% of all marriages. In some countries like Qatar, Yemen, and UAE, consanguinity rates are increasing in the current generation. Research among Arabs and worldwide has indicated that consanguinity could have an effect on some reproductive health parameters such as postnatal mortality and rates of congenital malformations. The association of consanguinity with other reproductive health parameters, such as fertility and fetal wastage, is controversial. The main impact of consanguinity, however, is an increase in the rate of homozygotes for autosomal recessive genetic disorders. Worldwide, known dominant disorders are more numerous than known recessive disorders. However, data on genetic disorders in Arab populations as extracted from the Catalogue of Transmission Genetics in Arabs (CTGA) database indicate a relative abundance of recessive disorders in the region that is clearly associated with the practice of consanguinity.

    Objectives Arab Americans constitute a large, heterogeneous, and quickly growing subpopulation in the United States. Health statistics for this group are difficult to find because US governmental offices do not recognize Arab as separate from white. The development and validation of an Arab- and Chaldean-American name database will enhance research efforts in this population subgroup. Methods A previously validated name database was supplemented with newly identified names gathered primarily from vital statistic records and then evaluated using a multistep process. This process included 1) review by 4 Arabic- and Chaldean-speaking reviewers, 2) ethnicity assessment by social media searches, and 3) self-report of ancestry obtained from a telephone survey. Results Our Arab- and Chaldean-American name algorithm has a positive predictive value of 91% and a negative predictive value of 100%. Conclusions This enhanced name database and algorithm can be used to identify Arab Americans in health statistics data, such as cancer and hospital registries, where they are often coded as white, to determine the extent of health disparities in this population.

    The Arabs comprise a genetically heterogeneous group that resulted from the admixture of different populations throughout history. They share many common characteristics responsible for a considerable proportion of perinatal and neonatal mortalities. To this end, the Centre for Arab Genomic Studies (CAGS) launched a pilot project to construct the ‘Catalogue of Transmission Genetics in Arabs’ (CTGA) database for genetic disorders in Arabs. Information in CTGA is drawn from published research and mined hospital records. The database offers web-based basic and advanced search approaches. In either case, the final search result is a detailed HTML record that includes text-, URL- and graphic-based fields. At present, CTGA hosts entries for 692 phenotypes and 235 related genes described in Arab individuals. Of these, 213 phenotypic descriptions and 22 related genes were observed in the Arab population of the United Arab Emirates (UAE). These results emphasize the role of CTGA as an essential tool to promote scientific research on genetic disorders in the region. The priority of CTGA is to provide timely information on the occurrence of genetic disorders in Arab individuals. It is anticipated that data from Arab countries other than the UAE will be exhaustively searched and incorporated in CTGA (). PMID:16381941

    1998-01-01

    Whole-tree water use in 4- and 8-year-old plantations of Eucalyptus nitens Deane and Maiden (ex Maiden) in the presence and absence of Acacia dealbata Link. weeds was estimated by the heat pulse velocity technique during a six-week summer period. Maximum sap velocities were recorded between 5 and 15 mm under the cambium for both eucalypt and acacia trees, and marked radial and axial variations in sap velocity were observed. The latter source of variation was most pronounced in mixed stands where crowns were asymmetrical. Mean daily sap flux ranged from 1.4 to 103.6 l day(-1) for eucalypts and from < 0.1 to 8.4 l day(-1) for acacias. Stem diameter explained 98% of the variation in sapwood area for E. nitens and 89% for A. dealbata, and was determined to be a suitable parameter for scaling water use from the tree to stand level. Plot transpiration varied from 1.4 to 2.8 mm day(-1) in mixed 8-year-old plots and was 0.85 mm day(-1) in a mixed 4-year-old plot. The degree of A. dealbata infestation was associated with absolute plot water use and regression models predicted that, in the absence of acacia competition, plot water use for the 8-year-old stand would approach 5-6 mm day(-1) during the growing season.

    The purpose of this study was to better understand barriers and facilitators of diabetes self-management education (DSME) among Arab American patients with diabetes. Little is known about the impact of Arab culture on DSME. Arab American adults (N = 23) with medically managed diabetes participated in 1 of 3 focus groups. An Arabic-speaking, trained moderator conducted video-recorded sessions. Verbatim Arabic transcripts were translated into English. Transcripts underwent a qualitative content analysis approach. Arab American cultural traditions such as food sharing, religious beliefs, and gender roles both facilitated and at times impeded DSME. Patients also held conflicting views about their interactions with their providers; some participants praised the authoritative patient-physician relationship style while others perceived the gaps in communication to be a product of Arab culture. Participants expressed that lack of available educational and supportive resources are key barriers to DSME. Arab American culture affects DSM activities, and culturally sensitive educational resources are lacking. Development of DSME programs tailored to address relevant aspects of Arab culture might improve DSME outcomes in Arab American population. © 2015 The Author(s).

    An experience of collaboration between researchers and the Ministry of Health of Senegal has encouraged the social uses of results from research on the health of communities. This article presents the contributions of partnership-based research to tackling health inequalities. Following a diagnostic shared with all the actors (practitioners and users) that allowed us to identify the reasons behind the under-utilization of well-equipped and renovated health establishments, three innovations were implemented: district surgery, complementary health insurance and flat-rate fees. In the four central regions of Senegal where this experiment was launched, the research that was carried out allowed for a better comprehension of the processes and challenges in ‘co-constructing’ knowledge between practitioners and researchers, in the context of relatively low access to healthcare. This article highlights the importance of this co-construction in encouraging concerted efforts to make relevant changes for improved, more equitable and more accessible local health services for communities.

    Acculturation to U.S. culture by Latinos and Asian Americans has been associated with increased prevalence of substance abuse. However, little is known about the association between acculturation and substance use among Arab Americans, or more specifically, among Arab-American treatment clients. In 156 Arab-American male treatment clients, we found that higher levels of U.S. acculturation were positively associated with increased prevalence of polysubstance abuse. This first report on a large series of Arab-American clients also found considerable within-group variability. These results can be used to develop treatment plans and work-force training on the importance of U.S. acculturation and variability within Arab Americans.

    This discussion of the United Arab Emirates focuses on the following: the people; geography; history; government; political conditions; defense; the economy; foreign relations; and relations between the US and the United Arab Emirates. In 1983 the population was estimated at 1,194,000. In 1984 the annual growth rate was negative. Life expectancy is about 60 years. Fewer than 20% of the population are UAE citizens. Indigenous Emiris are Arab; the rest of the population includes significant numbers of other Arabs -- Palestinians, Egyptians, Jordanians, Yemenis, Omanis, as well as many Iranians, Pakistanis, Indians, and West Europeans, especially in Dubai. The UAE is in the eastern Arabian Peninsula, bounded on the north by the Persian Gulf. European and Arab pirates roamed the Trucial Coast area from the 17th century into the 19th century. Early British expeditions against the pirates led to further campaigns against their headquarters. Piracy continued intermittently until 1835, when the shaikhs agreed not to engage in hostilities at sea. Primarily in reaction to the ambitions of other European countries, the UK and the Trucial States established closer bonds in an 1892 treaty. In 1968 the British government announced its decision, reaffirmed in March 1971, to end the treaty relationship with the gulf shaikhdoms. When the British protective treaty with the Trucial Shaikhdoms ended on December 1, they became fully independent. On December 2, 1971, 6 of them entered into a union called the United Arab Emirates. The 7th, Ras al-Khaimah, joined in early 1972. Administratively, the UAE is a loose federation of 7 emirates, each with its own ruler. The pace at which local government in each emirate is evolving, from traditional to modern, is set primarily by the ruler. Under the provisional constitution of 1971, each emirate reserves considerable powers, including control over mineral rights, taxation, and police powers. In this milieu, the growth of federal powers has

    Malnutrition and food insecurity are associated with increased mortality and poor clinical outcomes among people living with HIV/AIDS; however, the prevalence of malnutrition and food insecurity among people living with HIV/AIDS in Senegal, West Africa is unknown. The objective of this study was to determine the prevalence and severity of food insecurity and malnutrition among HIV-infected adults in Senegal, and to identify associations between food insecurity, malnutrition, and HIV outcomes. We conducted a cross-sectional study at outpatient clinics in Dakar and Ziguinchor, Senegal. Data were collected using participant interviews, anthropometry, the Household Food Insecurity Access Scale, the Individual Dietary Diversity Scale, and chart review. One hundred and nine HIV-1 and/or HIV-2 participants were enrolled. The prevalence of food insecurity was 84.6% in Dakar and 89.5% in Ziguinchor. The prevalence of severe food insecurity was 59.6% in Dakar and 75.4% in Ziguinchor. The prevalence of malnutrition (BMI <18.5) was 19.2% in Dakar and 26.3% in Ziguinchor. Severe food insecurity was associated with missing clinic appointments (p = 0.01) and not taking antiretroviral therapy due to hunger (p = 0.02). Malnutrition was associated with lower CD4 cell counts (p = 0.01). Severe food insecurity and malnutrition are highly prevalent among HIV-infected adults in both Dakar and Ziguinchor, and are associated with poor HIV outcomes. Our findings warrant further studies to determine the root causes of malnutrition and food insecurity in Senegal, and the short- and long-term impacts of malnutrition and food insecurity on HIV care. Urgent interventions are needed to address the unacceptably high rates of malnutrition and food insecurity in this population.

    The 22 Arab nations have a unique genetic structure, which reflects both conserved and diverse gene pools due to the prevalent endogamous and consanguineous marriage culture and the long history of admixture among different ethnic subcultures descended from the Asian, European, and African continents. Human genome sequencing has enabled large-scale genomic studies of different populations and has become a powerful tool for studying disease predictions and diagnosis. Despite the importance of the Arab genome for better understanding the dynamics of the human genome, discovering rare genetic variations, and studying early human migration out of Africa, it is poorly represented in human genome databases, such as HapMap and the 1000 Genomes Project. In this review, I demonstrate the significance of sequencing the Arab genome and setting an Arab genome reference(s) for better understanding the molecular pathogenesis of genetic diseases, discovering novel/rare variants, and identifying a meaningful genotype-phenotype correlation for complex diseases.

    Acacia aroma, native plant from San Luis, Argentina, is commonly used as antiseptic and for healing of wounds. The present study was conducted to investigate the in vitro cytotoxicity and genotoxicity of hot aqueous extract (HAE) and ethanolic extract (EE) of A. aroma. The cytotoxic activity was assayed by neutral red uptake assay on Vero cell. Cell treatment with a range from 100 to 5000 μg/mL of HAE and EE showed that 500 μg/mL and 100 μg/mL were the maximum noncytotoxic concentrations, respectively. The CC50 was 658 μg/mL for EE and 1020 μg/mL for HAE. The genotoxicity was tested by the single-cell gel electrophoresis comet assay. The results obtained in the evaluation of DNA cellular damage exposed to varied concentrations of the HAE showed no significant genotoxic effect at range of 1–20 mg/mL. The EE at 20 mg/mL showed moderate genotoxic effect related to the increase of the DNA percentage contained in tail of the comet; DNA was classified in category 2. At concentrations below 5 mg/mL, the results of cytotoxicity and genotoxicity of aqueous and ethanolic extracts of Acacia aroma guarantee the safety at cell and genomic level. However further studies are needed for longer periods including animal models to confirm the findings. PMID:25530999

    Eucalyptus U6 and Acacia crassicarpa were mixed planted with different ratios and modes to investigate the growth parameters of the two tree species. In the 2-3 years old mixed plantation, the wind-throw of A. crassicarpa decreased markedly with increasing ratio of Eucalyptus U6, the decrement being 26.14% when the Eucalyptus U6/A. crassicarpa ratio was 3 : 1, but the survival rates of Eucalyptus U6 and A. crassicarpa had no significant difference under different planting modes. Mixed planting retarded the A. crassicarpa growth to some extent, with the DBH being 90% of that in pure A. crassicarpa stand. The mixed planting had little effects on the height growth of Eucalyptus U6, but promoted its DBH growth markedly, and the beneficial effect increased with increasing ratio of A. crassicarpa. In the 6 years old 1 : 1 Eucalyptus U6/A. crassicarpa plantation, the Eucalyptus U6 individuals with DBH > 15 cm occupied 32.1%; while in pure Eucalyptus U6 stand, they only accounted for 5.83%. Mixed planting with 2 : 1 Eucalyptus U6/A. crassicarpa could obtain a maximum total biomass of 198.8 m3 x hm(-2), which was 118.8% of the total biomass in pure Eucalyptus U6 stand, or 169.9% of that in pure A. crassicarpa stand. Mixture of Eucalyptus with Acacia would be a good choice to produce Eucalyptus trees with larger DBH.

    Making misoprostol widely available for management of postpartum haemorrhage (PPH) and post abortion care (PAC) is essential for reducing maternal mortality. Private pharmacies (thereafter called "pharmacies") are integral in supplying medications to the general public in Senegal. In the case of misoprostol, pharmacies are also the main supplier to public providers and therefore have a key role in increasing its availability. This study seeks to understand knowledge and provision of misoprostol among pharmacy workers in Dakar, Senegal. A cross-sectional survey was conducted in Dakar, Senegal. 110 pharmacy workers were interviewed face-to-face to collect information on their knowledge and practice relating to the provision of misoprostol. There are low levels of knowledge about misoprostol uses, registration status, treatment regimens and side effects among pharmacy workers, and corresponding low levels of training on its uses for reproductive health. Provision of misoprostol was low; of the 72% (n = 79) of pharmacy workers who had heard of the product, 35% (n = 27) reported selling it, though rarely for reproductive health indications. Almost half (49%, n = 25) of the respondents who did not sell misoprostol expressed willingness to do so. The main reasons pharmacy workers gave for not selling the product included stock outs (due to product unavailability from the supplier), perceived lack of demand and unwillingness to stock an abortifacient. Knowledge and availability of misoprostol in pharmacies in Senegal is low, posing potential challenges for delivery of post-abortion care and obstetric care. Training is required to address low levels of knowledge of misoprostol registration and uses among pharmacy workers. Barriers that prevent pharmacy workers from stocking misoprostol, including weaknesses in the supply chain and stigmatisation of the product must be addressed. Low reported sales for reproductive health indications also suggest limited prescribing of

The seven Arab nations covered in this report-Bahrain, Iraq, Kuwait, Oman, Qatar, Saudi Arabia, and the United Arab Emirates--participate in several organizations focusing on regional cooperation regarding economic development, social programs, and Islamic unity, as well as organizations concerned with oil policies. This report focuses on the oil-related activities of the countries that may reveal the de facto oil policies of the seven Persian Gulf nations. Nevertheless it should bemore » kept in mind that the decision makers participating in the oil policy organizations are also involved with the collaborative efforts of these other organizations. Oil policies of five of the seven Arab nations are expressed within the forums of the Organization of Petroleum Exporting Countries (OPEC) and the Organization of Arab Petroleum Exporting Countries (OAPEC). Only Oman, among the seven, is not a member of either OAPEC or OPEC; Bahrain is a member of OAPEC but not of OPEC. OPEC and OAPEC provide forums for compromise and cooperation among their members. Nevertheless, each member state maintains its own sovereignty and follows its own policies.

    A considerable progress in recognition techniques for many non-Arabic characters has been achieved. In contrary, few efforts have been put on the research of Arabic characters. In any Optical Character Recognition (OCR) system the segmentation step is usually the essential stage in which an extensive portion of processing is devoted and a considerable share of recognition errors is attributed. In this research, a novel segmentation approach for machine Arabic printed text with diacritics is proposed. The proposed method reduces computation, errors, gives a clear description for the sub-word and has advantages over using the skeleton approach in which the data and information of the character can be lost. Both of initial evaluation and testing of the proposed method have been developed using MATLAB and shows 98.7% promising results.

    Mixed plantations with N-fixing species might be an attractive option for limiting the use of fertilizer in highly productive Eucalyptus plantations. A randomized block design was set up in southern Brazil, including a replacement series and an additive series design, as well as a nitrogen fertilization treatment, and conducted during a full 6 years rotation. The gradient of competition between Eucalyptus and Acacia in this design resulted in very different conditions of growth of Acacia, from totally dominated up to dominant canopies. We used the MAESTRA model to estimate the amount of absorbed photosynthetically active radiation (APAR) at tree level. This model requires the description of the scene and distinct structural variables of the two species, and their evolution with time. The competition for light is analysed by comparing the inter-specific values of APAR during a period of 2 years at the end of the rotation. APAR is further compared to the measured increment in stem wood biomass of the tree, and their ratio is an estimation of the light use efficiency for stemwood production at tree-scale. Variability of these LUE are analysed in respect to the species, the size of the tree, and at plot scale (competition level). Stemwood production was 3400, 3900 and 2400 gDM/m2 while APAR was 1640, 2280 and 2900 MJ/y for the pure Eucalyptus, pure Acacia and 50/50 mixed plantation, respectively, for an average LAI of 3.7, 3.3 and 4.5, respectively. Individual LUE for stemwood was estimated at an average value of 1.72 and 1.41 gDM/MJ/tree for Eucalyptus and Acacia, respectively, and at 0.92 and 0.40 gDM/MJ/tree when they were planted in mixed 50/50 plantations. LUE was highly dependant on tree size for both species. At the plot scale, LUE for stemwood were 2.1 gDM/MJ and 1.75 for Eucalyptus and Acacias, respectively, and 0.85 for the mixed 50/50 plantation. These results suggest that the mixed 50/50 plantation, which absorbed a higher amount of light, produce less

    Arabic, a Semitic language of the Afro-Asiatic variety, has a rich consonant inventory. Previous studies on Arabic phonological acquisition have focused primarily on dialects in Jordan and Egypt. Because Arabic varies considerably across regions, information is also needed for other dialects. To determine acquisition benchmarks for singleton consonants for Kuwaiti Arabic-speaking 4-year-olds. Participants were 80 monolingual Kuwaiti Arabic-speaking children divided into two age groups: 46-54 and 55-62 months. Post-hoc, eight children were identified as possibly at risk for protracted phonological development. A native Kuwaiti Arabic speaker audio-recorded and transcribed single-word speech samples (88 words) that tested consonants across word positions within a variety of word lengths and structures. Transcription reliability (point-to-point) was 95% amongst the authors, and 87% with an external consultant. Three acquisition levels were designated that indicated the proportion of children with no mismatches ('errors') for a given consonant: 90%+ of children, 75-89%, fewer than 75%. Mismatch patterns were described in terms of a phonological feature framework previously described in the literature. The Kuwaiti 4-year-olds produced many singleton consonants accurately, including pharyngeals and uvulars. Although the older age group had fewer manner and laryngeal mismatches than the younger age group, consonants still developing at age 5 included coronal fricatives and affricates, trilled /r/ and some uvularized consonants ('emphatics'). The possible at-risk group showed mastery of fewer consonants than the other children. By feature category, place mismatches were the most common, primarily de-emphasis and lack of contrast for [coronal, grooved] (distinguishing alveolar from interdental fricatives). Manner mismatches were next most common: the most frequent substitutions were [+lateral] [l] or other rhotics for /r/, and stops for fricatives. Laryngeal mismatches were

    To determine tobacco use rates (cigarette, water pipe smoking [WPS] or narghile) in Arab American compared to non-Arab youth. A convenience sample of 2,782 14- to 18-year-old high school students from a midwest community completed a 21-item tobacco use history survey. Seventy-one percent of the participants were ArA. Grades 9 through 12 were equally represented. Results included 'ever tried cigarettes [narghile]' (20%, 39%); 'smoked cigarettes [narghile] in the past 30 days' (7%, 22%); and 'regular smoking [narghile]' (3%, 15%) for ArA and non-Arab youths, respectively. Each was significantly related to grade and ethnicity. WPS for ArA and non-Arab youths was (38%, 21%); (17%, 11%); and (7%, 5%) for 'ever used,' 'used in the past 30 days,' and 'regular use,' respectively. Grade, ethnicity, and sex were significantly related to WPS. Cigarette smoking rates for non-Arab youth were lower than current national youth smoking rates but significantly higher than ArA youth. Rates for ArA youth were much lower than current national reported data. Rates of WPS for US youth, regardless of race or ethnicity, are not known. Findings from this study indicate that both ArA and non-Arab youth are experimenting and using WPS regularly. These results underscore the importance of assessing novel forms of tobacco use, particularly WPS, a growing phenomenon among US youth.

  12. Female Employment Reduces Fertility in Rural Senegal

    PubMed Central

    2015-01-01

    Economic growth and modernization of society are generally associated with fertility rate decreases but which forces trigger this is unclear. In this paper we assess how fertility changes with increased labor market participation of women in rural Senegal. Evidence from high-income countries suggests that higher female employment rates lead to reduced fertility rates but evidence from developing countries at an early stage of demographic transition is largely absent. We concentrate on a rural area in northern Senegal where a recent boom in horticultural exports has been associated with a sudden increase in female off-farm employment. Using survey data we show that employed women have a significantly higher age at marriage and at first childbirth, and significantly fewer children. As causal identification strategy we use instrumental variable and difference-in-differences estimations, combined with propensity score matching. We find that female employment reduces the number of children per woman by 25%, and that this fertility-reducing effect is as large for poor as for non-poor women and larger for illiterate than for literate women. Results imply that female employment is a strong instrument for empowering rural women, reducing fertility rates and accelerating the demographic transition in poor countries. The effectiveness of family planning programs can increase if targeted to areas where female employment is increasing or to female employees directly because of a higher likelihood to reach women with low-fertility preferences. Our results show that changes in fertility preferences not necessarily result from a cultural evolution but can also be driven by sudden and individual changes in economic opportunities.

    In this study, we explored the effect of salinity on cadmium (Cd) tolerance and phytoremediation potential of Acacia nilotica. Two-month-old uniform plants of A. nilotica were grown in pots contaminated with various levels of Cd (0, 5, 10, and 15 mg kg -1 ), NaCl (0%, 0.5%, 1.0% (hereafter referred as salinity), and all possible combinations of Cd + salinity for a period of six months. Results showed that shoot and root growth, biomass, tissue water content and chlorophyll (chl a, chl b, and total chl a+b) contents decreased more in response to salinity and combination of Cd + salinity compared to Cd alone. Shoot and root K concentrations significantly decreased with increasing soil Cd levels, whereas Na and Cl concentrations were not affected significantly. Shoot and root Cd concentrations, bioconcentration factor (BCF) and translocation factor (TF) increased with increasing soil Cd and Cd + salinity levels. At low level of salinity (0.5%), shoot and root Cd uptake enhanced, while it decreased at high level of salinity (1.0%). Due to Cd tolerance, high shoot biomass and shoot Cd uptake, this tree species has some potential for phytoremediation of Cd from the metal contaminated saline and nonsaline soils.

    In Sub-Saharan Africa, floodplains wetlands play an important role for livelihoods and economy, especially for agriculture and fishing. However, tropical rivers flows are increasingly modified by climate change and dam regulation. In the Senegal river valley, the annual flood, from August to November, is an important water resources creating ecosystems services for people. Senegal river basin face to hydrological changes, due to rainfall diminution during the 1970's and building of large dams during 1980's to secure water resources. Water management and development of irrigation have modified the floodplain functioning. Flood recession agriculture, grazing and fishing are now confronted to a high uncertainty about floods level, duration and extension. Thus, spatiotemporal information of flood extension and duration are important for local communities and stakeholders to ensure food security and ecosystems services. Multi-temporal satellite data demonstrates an important applicability for flood mapping. Aims of this work is to present potentiality of using multi-temporal data from MODIS and new satellite Sentinel-2 for flood monitoring in a Sahelian context. It will also discuss the potential of flood mapping for the analysis of the dynamics of riparian vegetation and flood recession agriculture. This study uses two datasets to explore flood monitoring in Senegal river valley. Firstly, MODIS 8-days data (MOD09A) are first used, because of its temporal resolution of 8 days covering the period from 2000 to 2016. However, MODIS data are limited due to a low spatial resolution, that's why we also use Sentinel-2 data, available since summer 2015. The data were processed by constructing NDWI time-series (NDWI threshold is empirically defined) and extracting NDWI values for each inundated pixel during flood. First results demonstrate that using MODIS on a large scale is enough for analyze interannual variability of the flooded surfaces. We present here maps of flood

    The prevalence of diabetes Mellitus in Saudi Arabia is 24%, ranking it among the top ten Worldwide. Diabetes education focuses on self-management and relies on numeracy skills. Poor numeracy may go unrecognized and it is important to have an assessment tool in Arabic to measure such a skill in diabetes care. To validate a 15-item Diabetes Numeracy Test (DNT-15) in the Arabic Language as a tool to assess the numeracy skills of patients with diabetes and to test its properties among Saudi patients with diabetes. A 15-question Arabic-language test to assess diabetes numeracy among patients with diabetes on the basis of the diabetes numeracy test (DNT-15) was validated among a sample Arabic speaking Saudi patients with diabetes. Data collection included patients' demographics, long-term glycemic control, diabetes type, duration, co-morbidities, and diabetes related knowledge questions. Internal reliability was assessed using Kuder-Richardson Formula 20 (KR-20). The average score of Arabic DNT-15 was 53.3% and took an average of 30 minutes to complete. The scores significantly correlated with education, income, HbA1c, and diabetes knowledge (p<0.05). Content Validity Ratio (CVR) of 0.75 and Content Validity Index (CVI) of 0.89 supported good content validity. The Arabic DNT-15 also had good internal reliability (KR20 = 0.90). Patients with diabetes need numeracy skills to manage their disease. Level of education does not reflect level of numeracy, and low numeracy skills might be unnoticed by health care providers. The Arabic DNT-15 is a valid and reliable scale to identify Arabic speaking patients with difficulties in certain diabetes-related numeracy skills.

    There is a lack of comparable data on physical activity, sedentary behavior, and dietary habits among Arab adolescents, which limits our understanding and interpretation of the relationship between obesity and lifestyle parameters. Therefore, we initiated the Arab Teens Lifestyle Study (ATLS). The ATLS is a multicenter collaborative project for assessing lifestyle habits of Arab adolescents. The objectives of the ATLS project were to investigate the prevalence rates for overweight and obesity, physical activity, sedentary activity and dietary habits among Arab adolescents, and to examine the interrelationships between these lifestyle variables. This paper reports on the objectives, design, methodology, and implications of the ATLS. The ATLS is a school-based cross-sectional study involving 9182 randomly selected secondary-school students (14-19 years) from major Arab cities, using a multistage stratified sampling technique. The participating Arab cities included Riyadh, Jeddah, and Al-Khobar (Saudi Arabia), Bahrain, Dubai (United Arab Emirates), Kuwait, Amman (Jordan), Mosel (Iraq), Muscat (Oman), Tunisia (Tunisia) and Kenitra (Morocco). Measured variables included anthropometric measurements, physical activity, sedentary behavior, sleep duration, and dietary habits. The ATLS project will provide a unique opportunity to collect and analyze important lifestyle information from Arab adolescents using standardized procedures. This is the first time a collaborative Arab project will simultaneously assess broad lifestyle variables in a large sample of adolescents from numerous urbanized Arab regions. This joint research project will supply us with comprehensive and recent data on physical activity/inactivity and eating habits of Arab adolescents relative to obesity. Such invaluable lifestyle-related data are crucial for developing public health policies and regional strategies for health promotion and disease prevention.

    The future information systems are expected to be more intelligent and will take human queries in natural language as input and answer them promptly. To develop a chatbot or a computer program that can chat with humans in realistic manner to extent that human get impressions that he/she is talking with other human is a challenging task. To make such chatbots, different technologies will work together ranging from artificial intelligence to development of semantic resources. Sophisticated chatbots are developed to perform conversation in number of languages. Arabic chatbots can be helpful in automating many operations and serve people who only know Arabic language. However, the technology for Arabic language is still in its infancy stage due to some challenges surrounding the Arabic language. This paper offers an overview of the chatbot application and the several obstacles and challenges that need to be resolved to develop an effective Arabic chatbot.

  2. Arabic OCR: toward a complete system

    Latin and Chinese OCR systems have been studied extensively in the literature. Yet little work was performed for Arabic character recognition. This is due to the technical challenges found in the Arabic text. Due to its cursive nature, a powerful and stable text segmentation is needed. Also; features capturing the characteristics of the rich Arabic character representation are needed to build the Arabic OCR. In this paper a novel segmentation technique which is font and size independent is introduced. This technique can segment the cursive written text line even if the line suffers from small skewness. The technique is not sensitive to the location of the centerline of the text line and can segment different font sizes and type (for different character sets) occurring on the same line. Features extraction is considered one of the most important phases of the text reading system. Ideally, the features extracted from a character image should capture the essential characteristics of this character that are independent of the font type and size. In such ideal case, the classifier stores a single prototype per character. However, it is practically challenging to find such ideal set of features. In this paper, a set of features that reflect the topological aspects of Arabia characters is proposed. These proposed features integrated with a topological matching technique introduce an Arabic text reading system that is semi Omni.

    This brief report, drawing from a multi-year effort by the U.S. Agency for International Development (USAID) Famine Early Warning Systems Network (FEWS NET), identifies modest declines in rainfall, accompanied by increases in air temperatures. These analyses are based on quality-controlled station observations. Conclusions: * Summer rains have remained steady in Senegal over the past 20 years but are 15 percent below the 1920-1969 average. * Temperatures have increased by 0.9° Celsius since 1975, amplifying the effect of droughts. * Cereal yields are low but have been improving. * The amount of farmland per person is low and declining rapidly. * Current population and agriculture trends could lead to a 30-percent reduction in per capita cereal production by 2025.

    Chemical composition and nutritional evaluation as well as physicochemical and functional properties of seed flour of Acacia tortilis (Forssk.) Hayne ssp. raddiana were studied. The results indicated that seeds contained 5.30% moisture, 3.99% ash, 9.19% fat, 14.31% fiber, 27.21% protein and 45.30% carbohydrates. Potassium was the predominant element followed by calcium and then phosphorous. Phytic acid, tannins and trypsin inhibitor as antinutrients were detected. The amino acid profile compared well with FAO/WHO recommended pattern except for cystine/methionine, isoleucine, tyrosine/phenylalanine, lysine and threonine. Also, the first limiting amino acid was lysine. Fatty acid composition showed that linoleic acid was the major fatty acid, followed by palmitic, stearic, oleic and arachidic acids. The seed oil showed absorbance in the ultraviolet ranges, thus it can be used as a broad spectrum UV protectant. For physicochemical and functional properties, acacia seeds flour had excellent water holding index, swelling index, foaming capacity and foam stability. Copyright © 2016 Elsevier Ltd.

    Atmospheric configuration and synoptic evolution of patterns associated with Senegalese heat wave (HW) are examined on the period 1979-2014 using the Global Surface Summary of the Day (GSOD) observational database and ERA-Interim reanalysis. Since there is no objective and uniform definition of HW events, threshold methods based on atmospheric variables as daily maximum (Tmax) / minimum (Tmin) temperatures and daily mean apparent temperature (AT) are used to define HW threshold detection. Each criterion is related to a specific category of HW events: Tmax (warm day events), Tmin (warm night events) and AT (combining temperature and moisture). These definitions are used in order to characterize as well as possible the warm events over the Senegalese regions (oceanic versus continental region). Statistics on time evolution and spatial distribution of warm events are carried out over the 2 seasons of maximum temperature (March-May and October-November). For each season, a composite of HW events, as well as the most extended event over Senegal (as a case study) are analyzed using usual atmospheric fields (sea level pressure, geopotential height, total column water content, wind components, 2m temperature). This study is part of the project ACASIS (https://acasis.locean-ipsl.upmc.fr/doku.php) on heat waves occurrences over the Sahel and their impact on health. Keywords: heat wave, Senegal, ACASIS.

    Effect of Acacia honey from north-west Nigeria on sodium arsenite-induced oxidative damage and clastogenicity in male Wistar rats was investigated. Animals were divided into four groups and were treated daily via oral gavage for one week before they were sacrificed. Brain, liver and blood serum were collected for antioxidant and protein assays. Clastogenicity, in vitro antioxidant activity, vitamins and minerals were also evaluated. From the results, co-administration of Acacia honey with sodium arsenite on the animals increased (P < 0.05) glutathione peroxidase, superoxide dismutase and catalase activities with concomitant decrease in malondialdehyde levels and anti-clastogenic effects relative to the group treated with sodium arsenite only. The honey possesses reducing power, high hydrogen peroxide scavenging activity, good amount of vitamins (A, C and E), flavonoids (5.08 ± 0.92 mg QE/100 g) and phenolics (5.40 ± 0.69 mg GAE/100 g). The minerals present include zinc, iron, sodium, magnesium, potassium and calcium. In conclusion, Acacia honey from Nigeria may mitigate oxidative stress and clastogenicity.

    Background Malnutrition and food insecurity are associated with increased mortality and poor clinical outcomes among people living with HIV/AIDS; however, the prevalence of malnutrition and food insecurity among people living with HIV/AIDS in Senegal, West Africa is unknown. The objective of this study was to determine the prevalence and severity of food insecurity and malnutrition among HIV-infected adults in Senegal, and to identify associations between food insecurity, malnutrition, and HIV outcomes. Methods We conducted a cross-sectional study at outpatient clinics in Dakar and Ziguinchor, Senegal. Data were collected using participant interviews, anthropometry, the Household Food Insecurity Access Scale, the Individual Dietary Diversity Scale, and chart review. Results One hundred and nine HIV-1 and/or HIV-2 participants were enrolled. The prevalence of food insecurity was 84.6% in Dakar and 89.5% in Ziguinchor. The prevalence of severe food insecurity was 59.6% in Dakar and 75.4% in Ziguinchor. The prevalence of malnutrition (BMI <18.5) was 19.2% in Dakar and 26.3% in Ziguinchor. Severe food insecurity was associated with missing clinic appointments (p = 0.01) and not taking antiretroviral therapy due to hunger (p = 0.02). Malnutrition was associated with lower CD4 cell counts (p = 0.01). Conclusions Severe food insecurity and malnutrition are highly prevalent among HIV-infected adults in both Dakar and Ziguinchor, and are associated with poor HIV outcomes. Our findings warrant further studies to determine the root causes of malnutrition and food insecurity in Senegal, and the short- and long-term impacts of malnutrition and food insecurity on HIV care. Urgent interventions are needed to address the unacceptably high rates of malnutrition and food insecurity in this population. PMID:26529509

    An understanding of the factors contributing to food insecurity and malnutrition among people living with HIV (PLHIV) in Senegal is urgently needed in order to develop effective interventions. The goals of this study were to identify differences in the dimensions of food security among PLHIV in Dakar versus Ziguinchor, Senegal, to determine which of these dimensions are most predictive of severe food insecurity, and to identify factors associated with malnutrition. We conducted a cross-sectional study at outpatient clinics in Dakar and Ziguinchor, Senegal. Data were collected using participant interviews, anthropometry, the Household Food Insecurity Access Scale, the Individual Dietary Diversity Scale, and chart review. Interviews were conducted with ninety-five food insecure, HIV-infected subjects. Daily household income and daily food expenditure per household member were the strongest predictors of severe food insecurity. The practice of agriculture, livestock ownership, nutritional status, and HIV outcomes were not predictive of severe food insecurity. CD4 count <350/mm 3 was the strongest predictor of malnutrition. Severe food insecurity, daily household income, daily food expenditure per household member, dietary diversity score, skipping meals, the practice of agriculture, livestock ownership, ART status, and adherence were not predictive of malnutrition. This is the first study to analyze the dimensions of food security among PLHIV in Senegal. We discovered important differences in food access, availability, stability, and utilization in Dakar versus Ziguinchor. We found that economic access was the strongest predictor of severe food insecurity and poorly controlled HIV was the strongest predictor of malnutrition. Our findings suggest that the interventions needed to address food insecurity differ from those necessary to target malnutrition, and that effective interventions may differ in Dakar versus Ziguinchor. Furthermore, this study highlights a need for

    Arab nations are decades behind many other previously colonized nations in developing stronger economies, more democratic institutions, and more autonomy and self-government, in part as a result of external interference. The year 2011 brought the potential for greater Arab autonomy through popular uprisings against autocratic governments in Tunisia, Egypt, and Yemen, and through the Palestinian request for state recognition by the United Nations. We examined the psychology of support for Arab ascendancy among adults in 14 nations in the Balkans, the Middle East, Asia, Oceania, Europe, and North America. We predicted and found that people low on social dominance orientation endorsed forming an independent Palestinian state and desired that the Arab uprisings succeed. Rejection of ideologies that legitimize outside interference with Arabs mediated this support. Measures and model results were robust across world regions. We discuss theoretical implications regarding the advent of new ideologies and extending social dominance theory to address international relations.

  17. Cross-border Ties and Arab American Mental Health

    PubMed Central

    Due to increasing discrimination and marginalization, Arab Americans are at a greater risk for mental health disorders. Social networks that include ties to the country of origin could help promote mental well-being in the face of discrimination. The role of countries of origin in immigrant mental health receives little attention compared to adjustment in destination contexts. This study addresses this gap by analyzing the relationship between nativity, cross-border ties, and psychological distress and happiness for Arab Americans living in the greater Detroit Metropolitan Area (N=896). I expect that first generation Arab Americans will have more psychological distress compared to one and half, second, and third generations, and Arab Americans with more cross-border ties will have less psychological distress and more happiness. Data come from the 2003 Detroit Arab American Study, which includes measures of nativity, cross-border ties – attitudes, social ties, media consumption, and community organizations, and the Kessler-10 scale of psychological distress and self-reported happiness. Ordered logistic regression analyses suggest that psychological distress and happiness do not vary much by nativity alone. However, cross-border ties have both adverse and protective effects on psychological distress and happiness. For all generations of Arab Americans, cross-border attitudes and social ties are associated with greater odds of psychological distress and for first generation Arab Americans, media consumption is associated with greater odds of unhappiness. In contrast, for all generations, involvement in cross-border community organizations is associated with less psychological distress and for the third generation, positive cross-border attitudes are associated with higher odds of happiness. These findings show the complex relationship between cross-border ties and psychological distress and happiness for different generations of Arab Americans. PMID:26999416

    A study was performed to determine the transmission and prevalence of human schistosomiasis in the Mauritanian side of the Senegal River basin. Parasitological investigations by Kato-Katz and urine filtration conducted on 1,259 school children indicated a mean prevalence of S. haematobium--29.0%, 25.9% and 34.3%, respectively, in the children of the lower, middle and high valley. Only the school children of the lower delta valley were infected by S. mansoni with a mean prevalence rate of 21.5%. The malacological investigations carried out in the water points of each visited village highlighted the presence of B. pfeifferi, B. senegalensis, B. globosus, B. umbilicatus, B. truncatus and B. forskalii. The last three species are announced for the first time in the Mauritanian side of the Senegal River. The laboratory snail infection experiments indicate that B. senegalensis and B. globosus are the most important intermediate hosts for S. haematobium in the Mauritanian side of the Senegal River basin. However, an incompatibility between the oasis strains of S. haematobium and the snails of the lower valley was noted. In the middle valley and high valley, the infection of the school children takes place during the rainy season, because of the creation of the temporary water points, in the lower valley; the transmission seems to be continuous.

    Aspects of the industrial archaeology of the northwestern part of the island of Cyprus are outlined. Wastes resultant from copper mining activities of approximately two millennia ago continue to exert an important influence on organisms. Detailed chemical analysis of two tree species growing on archaeologically important metalliferous spoil tips has indicated their ability to bioaccumulate heavy metals and sulfur primarily from the substratum; the bioaccumulation and biomagnification of lead and sulfur are particularly marked in both Acacia and Eucalyptus. The concentrations of elements in different parts of the two tree species are discussed and partitioning is noted together with the fact that while the pod of Acacia and the fruit capsule of Eucalyptus may have an enhanced metal loading, the values in the seeds are much reduced; the importance of this is discussed. The seeds of Acacia differ chemically from those of Eucalyptus. The importance of these plants as biomonitors of environmental quality is noted. Copyright 2001 Academic Press.

    Contraceptive prevalence is very low in Senegal, particularly among young women. Greater knowledge is needed about the barriers young women face to using contraceptives, including barriers imposed by health providers. Survey data collected in 2011 for the evaluation of the Urban Reproductive Health Initiative in Senegal were used to examine contraceptive use, method mix, unmet need and method sources among urban women aged 15-29 who were either currently married or unmarried but sexually active. Data from a sample of family planning providers were used to examine the prevalence of contraceptive eligibility restrictions based on age and marital status, and differences in such restrictions by method, facility type and provider characteristics. Modern contraceptive prevalence was 20% among young married women and 27% among young sexually active unmarried women; the levels of unmet need for contraception-mostly for spacing-were 19% and 11%, respectively. Providers were most likely to set minimum age restrictions for the pill and the injectable-two of the methods most often used by young women in urban Senegal. The median minimum age for contraceptive provision was typically 18. Restrictions based on marital status were less common than those based on age. Training and education programs for health providers should aim to remove unnecessary barriers to contraceptive access.

    Discoveries from the human genome, HapMap, and 1000 genome projects have collectively contributed toward the creation of a catalog of human genetic variations that has improved our understanding of human diversity. Despite the collegial nature of many of these genome study consortiums, which has led to the cataloging of genetic variations of different ethnic groups from around the world, genome data on the Arab population remains overwhelmingly underrepresented. The National Arab Genome project in the United Arab Emirates (UAE) aims to address this deficiency by using Next Generation Sequencing (NGS) technology to provide data to improve our understanding of the Arab genome and catalog variants that are unique to the Arab population of the UAE. The project was conceived to shed light on the similarities and differences between the Arab genome and those of the other ethnic groups.

    Time series of rainfall data and normalized difference vegetation index (NDVI) were used to evaluate land cover performance in Senegal, Africa, for the period 1982–1997, including analysis of woodland/forest, agriculture, savanna, and steppe land cover types. A strong relationship exists between annual rainfall and season-integrated NDVI for all of Senegal (r=0.74 to 0.90). For agriculture, savanna, and steppe areas, high positive correlations portray ‘normal’ land cover performance in relation to the rainfall/NDVI association. Regions of low correlation might indicate areas impacted by human influence. However, in the woodland/forest area, a negative or low correlation (with high NDVI) may reflect ‘normal’ land cover performance, due in part to the saturation effect of the rainfall/NDVI association. The analysis identified three areas of poor performance, where degradation has occurred over many years. Use of the ‘Standard Error of the Estimate’ provided essential information for detecting spatial anomalies associated with land degradation.

    Although nearly 112 million residents of the United States belong to a non-white ethnic group, the literature about differences in health indicators across ethnic groups is limited almost exclusively to Hispanics. Features of the social experience of many ethnic groups including immigration, discrimination, and acculturation may plausibly influence mortality risk. We explored life expectancy and age-adjusted mortality risk of Arab-Americans (AAs), relative to non-Arab and non-Hispanic Whites in Michigan, the state with the largest per capita population of AAs in the US. Data were collected about all deaths to AAs and non-Arab and non-Hispanic Whites in Michigan between 1990 and 2007, and year 2000 census data were collected for population denominators. We calculated life expectancy, age-adjusted all-cause, cause-specific, and age-specific mortality rates stratified by ethnicity and gender among AAs and non-Arab and non-Hispanic Whites. Among AAs, life expectancies among men and women were 2.0 and 1.4 years lower than among non-Arab and non-Hispanic White men and women, respectively. AA men had higher mortality than non-Arab and non-Hispanic White men due to infectious diseases, chronic diseases, and homicide. AA women had higher mortality than non-Arab and non-Hispanic White women due to chronic diseases. Despite better education and higher income, AAs have higher age-adjusted mortality risk than non-Arab and non-Hispanic Whites, particularly due to chronic diseases. Features specific to AA culture may explain some of these findings. © 2011 El-Sayed et al.

    2012-01-01

    The global epidemic of diabetes has not spared the Arabic-speaking countries, which have some of the highest prevalence of type II diabetes. This is particularly true of the Arab Gulf, a conglomerate of high income, oil-producing countries where prevalence rates are the highest. The prevalence rates among adults of the Arabic speaking countries as a whole range between 4%–21%, with the lowest being in Somalia and the highest in Kuwait. As economic growth has accelerated, so has the movement of the populations to urban centers where people are more likely to adopt lifestyles that embrace increased high-calorie food consumption and sedentary lifestyles. These factors likely contribute to the increased prevalence of obesity and diabetes in the Arabic speaking countries. PMID:22851968

    2006-05-01

    The automatic recognition of text on scanned images has enabled many applications such as searching for words in large volumes of documents, automatic sorting of postal mail, and convenient editing of previously printed documents. The domain of handwriting in the Arabic script presents unique technical challenges and has been addressed more recently than other domains. Many different methods have been proposed and applied to various types of images. This paper provides a comprehensive review of these methods. It is the first survey to focus on Arabic handwriting recognition and the first Arabic character recognition survey to provide recognition rates and descriptions of test data for the approaches discussed. It includes background on the field, discussion of the methods, and future research directions.

  17. MAWRID: A Model of Arabic Word Reading in Development.

    PubMed

    Saiegh-Haddad, Elinor

    2017-07-01

    This article offers a model of Arabic word reading according to which three conspicuous features of the Arabic language and orthography shape the development of word reading in this language: (a) vowelization/vocalization, or the use of diacritical marks to represent short vowels and other features of articulation; (b) morphological structure, namely, the predominance and transparency of derivational morphological structure in the linguistic and orthographic representation of the Arabic word; and (c) diglossia, specifically, the lexical and lexico-phonological distance between the spoken and the standard forms of Arabic words. It is argued that the triangulation of these features governs the acquisition and deployment of reading mechanisms across development. Moreover, the difficulties that readers encounter in their journey from beginning to skilled reading may be better understood if evaluated within these language-specific features of Arabic language and orthography.

    Senegal's National Malaria Control Programme (NMCP) implements control interventions in the form of targeted packages: (1) scale-up for impact (SUFI), which includes bed nets, intermittent preventive treatment in pregnancy, rapid diagnostic tests, and artemisinin combination therapy; (2) SUFI + reactive case investigation (focal test and treat); (3) SUFI + indoor residual spraying (IRS); (4) SUFI + seasonal malaria chemoprophylaxis (SMC); and, (5) SUFI + SMC + IRS. This study estimates the cost effectiveness of each of these packages to provide the NMCP with data for improving allocative efficiency and programmatic decision-making. This study is a retrospective analysis for the period 2013-2014 covering all 76 Senegal districts. The yearly implementation cost for each intervention was estimated and the information was aggregated into a package cost for all covered districts. The change in the burden of malaria associated with each package was estimated using the number of disability adjusted life-years (DALYs) averted. The cost effectiveness (cost per DALY averted) was then calculated for each package. The cost per DALY averted ranged from $76 to $1591 across packages. Using World Health Organization standards, 4 of the 5 packages were "very cost effective" (less than Senegal's GDP per capita). Relative to the 2 other packages implemented in malaria control districts, the SUFI + SMC package was the most cost-effective package at $76 per DALY averted. SMC seems to make IRS more cost effective: $582 per DALY averted for SUFI + IRS compared with $272 for the SUFI + IRS + SMC package. The SUFI + focal test and treat, implemented in malaria elimination districts, had a cost per DALY averted of $1591 and was only "cost-effective" (less than three times Senegal's per capita GDP). Senegal's choice of deploying malaria interventions by packages seems to be effectively targeting high burden areas with a wide range of interventions

    To evaluate the frequency of glucose-6-phosphate dehydrogenase (G-6-PD) deficiency, the incidence of clinically significant jaundice (any serum total bilirubin value >75th percentile on the hour-specific bilirubin nomogram), and the need for phototherapy in the pooled male Israeli-Arab and Palestinian-Arab population born at the Shaare Zedek Medical Center in Jerusalem, Israel. Quantitative G-6-PD enzyme testing of umbilical cord blood was performed during birth hospitalization. G-6-PD deficiency was defined as any G-6-PD value <7.0 U/gHb. Transcutaneous bilirubin was performed daily during birth hospitalization, with serum total bilirubin testing in those with a transcutaneous bilirubin value >75th percentile. Ten of 286 (3.5%) consecutively delivered male Arab newborns had G-6-PD deficiency. Clinically significant jaundice was higher in the population with G-6-PD deficiency compared with normal controls (relative risk, 3.45; 95% CI, 1.24-9.58). Thirty percent of the newborns with G-6-PD deficiency met American Academy of Pediatrics indications for phototherapy according to the high-risk (middle) curve on the phototherapy graph. The frequency of G-6-PD deficiency in the Arab neonatal population delivering at this medical center meets World Health Organization criteria for neonatal G-6-PD screening (3%-5%). As in other ethnic groups, clinically significant jaundice is more frequent in newborns of this ethnic group with G-6-PD deficiency compared with G-6-PD-normal controls. Neonatal G-6-PD screening for both males and females of this population subgroup, in conjunction with parental education regarding the dangers of the condition and its prophylaxis, has now been incorporated into our institution's routine G-6-PD screening program.

    2012-04-01

    To determine the relationship between acculturation and health status among Arab Americans in southern California. A cross-sectional survey with 297 adult Arab Americans used (a) a demographic and health survey, SF-36 Version-1, to assess physical and mental health and (b) the Acculturation Rating Scale for Arab Americans-II to assess acculturation. Participants reported significantly better physical health and worse mental health compared to the published norm for the 1998 U.S. population. Better physical health was associated with demographic factors and bicultural identification; better mental health was associated with attraction to American culture. Attraction to American culture predicted alcohol use, whereas attraction to Arabic culture predicted cigarette smoking. Different patterns of association existed between acculturation and physical and mental health among Arab Americans. Findings suggest that acculturation is an important factor to consider in the well-being of Arab Americans, especially in their mental health.

    Adolescent depression is a primary cause of global disability and burden with considerable variability across countries in its prevalence, diagnosis, management, and prognosis. No systematic reviews have been published on adolescent depression in Arab countries despite the unique sociocultural background that can play a major role in shaping Arab depressed adolescents' prognosis and response to treatment. The purpose of this study was to provide such a review with the goal of identifying the necessary foundations for culturally competent mental health care practices to address the unique needs of Arab adolescents and their families. We systematically reviewed PubMed, CINAHL, PsycINFO, and available Arabic databases. We adhered to the PRISMA statement to guide the process of identification, selection, and appraisal of the reviewed articles. No restrictions were applied on publication date. The search was completed in December 2015. A total of 199 unique articles met criteria for screening at the abstract level; 47 articles were selected for review in full text; and 27 articles were included in the final analysis. Four emerging themes were identified: (1) few robust prevalence estimates of adolescent depression are available in Arab countries; (2) depression varies based on the individual characteristics of Arab adolescents; (3) context influences Arab adolescents' risk of experiencing depression; and (4) the stigma of depression negatively impacts help-seeking process among Arab adolescents. This review highlights the need for more community-based detection efforts that employ developmentally and culturally appropriate measurement instruments for adolescent depression. Furthermore, findings suggest the need for culturally competent care that integrates indigenous health practices into modern mental health systems. Nurses, who form the greatest proportion of health personnel in all Arab countries, are uniquely situated to help Arab adolescents experiencing

    This review article underlines individual Traditional Islamic and Arabic plant (TAI) and their role in treating cancer. The aim of the study is to specifically evaluate the progress of herbs, Arabic and Islamic traditional herbs in particular, applied in cancer treatment, so far. Islamic and Arabic plants were selected and identified through different literature survey using "Google scholar", "Web of science", "Scopus" and "PubMed". Each plant, from identified Arabic and Islamic plants list, was search individually for the most cited articles in the aforementioned databases using the keywords, "Anticancer", "Uses in cancer treatment", "Ethno pharmacological importance in cancer" etc. The current review about Islamic and Arabic plants illuminates the importance of Islamic and Arabic plants and their impact in treating cancer. There is a long list of Islamic and Arabic plants used in cancer as mentioned in review with enormous amount of literature. Each plant has been investigated for its anticancer potential. The literature survey as mentioned in table shows; these plants are widely utilized in cancer as a whole, a part thereof or in the form of isolated chemical constituent. This review strongly supports the fact; Arabic and Islamic traditional plants have emerged as a good source of complementary and alternative medicine in treating cancer. Traditional Arab-Islamic herbal-based medicines might be promising for new cancer therapeutics with low toxicity and minimal side effects. The plants used are mostly in crude form and still needs advance research for the isolation of phytochemicals and establishing its cellular and molecular role in treating cancer.

    Mutations in the KCNJ11 and ABCC8 genes that encode the pancreatic K(ATP) channel are the commonest cause of permanent neonatal diabetes mellitus (PNDM). The authors aimed to define the genetic causes of PNDM in a large cohort of Arab patients and compare them with a British cohort tested in the same laboratory. Retrospective observational study. International genetics centre. Arab and British subjects with PNDM who were referred for genetic testing over the same period. Comparison of genotypes and phenotypes between the two cohorts. The aetiology and phenotype of PNDM in an Arab compared to a British cohort. 88 Arab and 77 British probands were referred between 2006 and 2011, inclusive. Consanguinity was higher among Arabs (63.6% vs 10.4%) and a higher percentage had a genetic diagnosis compared to the British cohort (63.6% vs 41.6%). Recessive EIF2AK3 gene mutations were the commonest cause of PNDM in the Arab cohort (22.7%) followed by INS (12.5%), and KCNJ11 and GCK (5.7% each), whereas K(ATP) channel mutations were the commonest cause (29.9%) in the British cohort. In 37.5% of Arab patients PNDM was part of a genetic syndrome compared to 7.8% of the British cohort. PNDM in the Arab population has a different genetic spectrum compared to British patients where KATP channel mutations are the commonest cause, similar to other European populations. In Arabs, PNDM is more likely to be part of a recessively inherited syndrome, possibly due to the higher rate of consanguinity.

    Background Q fever is a worldwide zoonotic disease caused by Coxiella burnetii. Epidemiologically, animals are considered reservoirs and humans incidental hosts. Methodology/Principal Findings We investigated Q fever in rural Senegal. Human samples (e.g., sera, saliva, breast milk, feces) were screened in the generally healthy population of two villages of the Sine-Saloum region. Ticks were collected in four regions. Seroprevalence was studied by immunofluorescence, and all other samples were tested by two qPCR systems for detection of C. burnetii. Positive samples were genotyped (multispacer typing) by amplification and sequencing of three spacers. Strains were isolated by cell culture. We found that the seroprevalence may be as high as 24.5% (59 of 238 studied) in Dielmo village. We identified spontaneous excretion of C. burnetii by humans through faeces and milk. Hard and soft ticks (8 species) were infected in 0–37.6%. We identified three genotypes of C. burnetii. The previously identified genotype 6 was the most common in ticks in all studied regions and the only one found in human samples. Three strains of genotype 6 of C. burnetii were also recovered from soft tick Ornithodoros sonrai. Two other genotypes found in ticks, 35 and 36, were identified for the first time. Conclusions/Significance Q fever should be considered a significant public health threat in Senegal. Humans, similar to other mammals, may continuously excrete C. burnetii. PMID:20386603

    2000-01-01

    Over the past 35 years, an agricultural area of west-central Senegal has experienced rapid population growth, fast expansion of agricultural lands, a decline in rainfall, and degradation of vegetative and soil resources. Although such changes have not escaped the attention of Senegal's people, its government, and the scientific community the ability to monitor and quantify land resource trends of recent decades has been difficult. Recently available high-resolution satellite photographs from the American Argon and Corona Programs provide coverage of Senegal back to 1963. The photographs make it possible to study and map land resources at the beginning of the Space Age. In this study, we characterize the changes that have occurred in the region from the early 1960s to the mid-1 990s. Early Argon and Corona photographs are used to reconstruct the historical land use and land cover; comparisons are made with assessments from recent Landsat images. Field studies and aerial surveys provide additional insight. The forces of change, driven primarily by population growth and unsustainable agricultural practices, are examined

    Hookah smoking is more prevalent among individuals of Middle Eastern descent. This study examined general and ethnic-specific risk factors for hookah smoking among Arabs and Chaldeans. A self-administered anonymous questionnaire was conducted among 801 adults residing in Southeast Michigan. Binary logistic regression modeling was used to predict risk factors for hookah smoking. Hookah smoking was significantly more prevalent among Arabs (32%) than Chaldeans (26%, p < 0.01) and being Arab was a risk factor for lifetime hookah use. Younger age (<25 years), being male, higher annual income, and having health insurance were significant risk factors for hookah use. Chaldeans believed to a greater extent than Arabs that smoking hookah is less harmful than cigarette smoking (75 vs. 52%, p < 0.001). Hookah smoking is prevalent in both ethnic groups, but significantly higher among Arabs. Results indicate that prevention efforts should target younger males with higher incomes.

    Knowledge of the genetic make-up and demographic history of invasive populations is critical to understand invasion mechanisms. Commensal rodents are ideal models to study whether complex invasion histories are typical of introductions involving human activities. The house mouse Mus musculus domesticus is a major invasive synanthropic rodent originating from South-West Asia. It has been largely studied in Europe and on several remote islands, but the genetic structure and invasion history of this taxon have been little investigated in several continental areas, including West Africa. In this study, we focussed on invasive populations of M. m. domesticus in Senegal. In this focal area for European settlers, the distribution area and invasion spread of the house mouse is documented by decades of data on commensal rodent communities. Genetic variation at one mitochondrial locus and 16 nuclear microsatellite markers was analysed from individuals sampled in 36 sites distributed across the country. A combination of phylogeographic and population genetics methods showed that there was a single introduction event on the northern coast of Senegal, from an exogenous (probably West European) source, followed by a secondary introduction from northern Senegal into a coastal site further south. The geographic locations of these introduction sites were consistent with the colonial history of Senegal. Overall, the marked microsatellite genetic structure observed in Senegal, even between sites located close together, revealed a complex interplay of different demographic processes occurring during house mouse spatial expansion, including sequential founder effects and stratified dispersal due to human transport along major roads.

    Arabic breads is produced mainly from hard red winter wheat (HRWW) and have relatively little crumb, dense texture, form pocket and are often round with golden brown crust color. The objectives of this research were to investigate the effect of different bread improvers combinations addition in enhancing the quality parameters of Arabic bread. Therefore, the ability of Arabic bread for rolling, folding and overall quality were evaluated during the Arabic bread storage period for 2 days. It was found that there was significant effect of bread improvers combinations (Arabic gum "AG" * Mongglycerides "MG" *alpha-amylase) addition on the ability of Arabic bread for rolling and folding on the second day (P ≤ 0.1). The highest white Arabic bread quality was obtained significantly from addition of low AG, high of MG and high alpha-amylase combination and high AG, low of MG and high alpha-amylase combination. While, low of AG, high of MG and low alpha-amylase combination and high of AG, high of MG and low alpha-amylase combination significantly exhibited the highest overall quality for the Arabic bread made from whole flour.

    2018-01-05

    The 2012 London Summit on Family Planning set ambitious goals to enable 120 million more women and adolescent girls to use modern contraceptives by 2020. The Urban Reproductive Health Initiative (URHI) was a Bill & Melinda Gates Foundation funded program designed to help contribute to these goals in urban areas in India, Kenya, Nigeria, and Senegal. URHI implemented a range of country-specific demand and supply side interventions, with supply interventions generally focused on improved service quality, provider training, outreach to patients, and commodity stock management. This study uses data collected by the Measurement, Learning & Evaluation (MLE) Project to examine the effectiveness of these supply-side interventions by considering URHI's influence on the number of family planning clients at health facilities over a four-year period in Kenya, Nigeria, and Senegal. The analysis used facility audits and provider surveys. Principal-components analysis was used to create country-specific program exposure variables for health facilities. Fixed-effects regression was used to determine whether family planning uptake increased at facilities with higher exposure. Outcomes of interest were the number of new family planning acceptors and the total number of family planning clients per reproductive health care provider in the last year.

    The interaction between glycinin and anionic polysaccharides has gained considerable attention recently because of its scientific impact on the stability of acid soymilk systems. In this study, the formation of glycinin/gum arabic complexes driven by electrostatic interactions was investigated. Turbidity titrations at different glycinin/gum arabic ratios were conducted and critical pH values (pH φ1 ) where insoluble complexes began forming were determined firstly. The corresponding pH φ1 values at glycinin/gum arabic ratios of 1:4, 1:2, 1:1, 2:1, 4:1 and 8:1 were 2.85, 3.25, 3.70, 4.40, 4.85 and 5.35, respectively. Afterwards, electromobilities for glycinin and gum arabic at the pH values between 4.1 and 2.6 were measured, and charge densities (ZN) for glycinin and gum arabic were calculated based on the soft particle analysis theory. Further analysis indicated that the product of glycinin/gum arabic ratio (ρ) and ZN ratio of glycinin/gum arabic was approximate 1 at any pH φ1 values. It was revealed that charge neutralization was achieved when glycinin/gum arabic insoluble complexes began forming. NaCl displayed multiple effects on glycinin/gum arabic complex formation according to turbidity and compositional analysis. The present study could provide basic guidance in acid soymilk designing.

    Arabs in Israel have high morbidity and mortality from diabetes and cardiovascular disease. Obesity is a risk factor for both conditions. To investigate the prevalence of obesity (body mass index >30 kg/m2), subjects' knowledge and behaviors, and their reports on practices of health-care professionals regarding body weight among Arabs and Jews. The study participants (n=880) were randomly sampled from the urban population of the Hadera district in Israel. Data on demographic, socioeconomic and lifestyle characteristics; reports on height, current body weight and body weight at the age of 18 years; knowledge and behavior; and health-care professionals' practices with regard to body weight were obtained by interview. Anthropometric measurements were performed subsequently. Information on BMI was available on 868 participants (49% Arabs, 49% women, median age 46 years). Although the median BMI did not differ significantly between Arabs and Jews at age 18, the prevalence of current obesity was 52% in Arab women compared to 31% in Jewish women (P < 0.001), and 25% in Arab men compared to 23% in Jewish men (P = 0.6). On multivariate analysis, obesity was significantly associated with age, BMI at the age of 18 years, leisure time physical activity and cigarette smoking, but not with ethnicity. Fewer Arabs reported measuring their body weight and Arab women were less frequently advised to maintain an active lifestyle. The high prevalence of obesity among Arab women may be explained by lifestyle characteristics. Prevention of obesity in Arabs should be directed at women and should start preferably before adulthood.

  2. Arab immigrants: a new case for ethnicity and health?

    PubMed

    Read, Jen'nan Ghazal; Amick, Benjamin; Donato, Katharine M

    2005-07-01

    Community-based studies of Arab Americans point to significant health problems among the immigrants, a finding that runs contrary to theories of immigrant selectivity. This study is the first to use nationally representative data to test this question. Using new questions that identify region of birth in the 2000 and 2001 National Health Interview Surveys, we compare the self-rated health and activity limitation of Arab immigrants to US-born white Americans and test the extent to which social, demographic, and immigrant characteristics account for observed disparities. The results find that Arab immigrants do not significantly differ from US-born whites in their self-rated health and are less likely to report limitations in activity. Length of time in the US has no composite effect on health; however, US citizenship does. Compared to the most recent immigrant arrivals, Arab immigrants who are citizens report worse health while their peers who are not officially American (non-citizens) do not, regardless of their duration of US residency. Contrary to prior studies on Arab health, we find that Arab immigrants are not uniformly disadvantaged in their health outcomes and that their health profile is more diverse than currently documented. The results also suggest that controlling for years of US residency may be insufficient for capturing the cumulative effects of acculturation on immigrant health. We conclude by suggesting avenues of future research for capturing heterogeneity among emergent ethnic populations such as Arab Americans.

  3. Managing terror: differences between Jews and Arabs in Israel.

    2009-04-01

    Using telephone surveys, we examined exposure to terror, coping, and mental health response in randomly selected Jewish-Israelis (n = 100) and Arab-Israelis (n = 100) living in five Israeli cities affected by terrorism. Jewish-Israelis and Arab-Israelis were randomly selected for study participation and completed telephone surveys in May 2002, following an extended string of terror attacks and hostilities. Although terrorism is designed to target Jewish-Israelis, the rates of exposure were similar in the two groups. Arab-Israelis reported using a wider array of coping strategies, yet also endorsed more frequent PTSD and more severe depression symptoms than Jewish-Israelis. We examined a variety of demographic, ethnic, and religious predictors of different coping styles and found varying results. For example, acceptance coping was best predicted by Arab-Israeli ethnicity, being female, greater religiosity, and lower education. Predictors of mental health response to terror were also examined, with Arab-Israeli ethnicity, being female, adaptation coping and collaborative coping best predicting PTSD and depression symptoms. Arab-Israelis may not have the same access to overarching sources of patriotic support that are readily available to their Jewish compatriots, and civilian and economic inequity experienced by the Arab minority may add to a sense of diminished resources. Our findings justify outreach efforts to overlooked minorities at risk for posttraumatic distress. Women seem to be at particular risk for the development of mental health symptoms following terrorism, which should also be noted for outreach purposes.

    The Israeli society is a unique setting in which the Arabs are exposed to western alcohol consumption norms while living in Arab communities where alcohol consumption is not accepted. To characterize Arab Muslim, Druze and Christian alcohol consumption behaviors and contingencies while being exposed to western style alcohol consumption. This study was a phenomenological qualitative study interviewing six focus groups and 13 individual Arab Muslims, Christians and Druze. Themes and categories were identified using qualitative methodology analysis. Two concurrent contingencies exist for Arab Muslim men: on the one hand they describe pressure to drink because of social norms, and on the other hand they are reprehended for drinking, because of the religious interdiction. Therefore, they hide their drinking in secluded places. In addition, participants reported more heavy drinking among Muslim Men. Arab Christians reported drinking openly especially among men. Women do not drink and are looked down upon if they drink. Drinking may be viewed as a stage in life that a Muslim boy or young man goes through, he is expected to grow out of this stage and stop drinking while becoming religious. Conclusions/importance: Due to Muslim laws prohibiting alcohol consumption, alcohol consumption is not high, however it does exist especially among young men and when they drink they tend to drink heavily, more than the Arab Christians. Therefore, there is a need for interventions targeting younger Muslim men, to establish moderate drinking behaviors, if they chose to drink.

    The autosomal recessive Canavan disease (CD) is a neurological disorder that begins in infancy. CD is caused by mutations in the gene encoding the ASPA enzyme. It has been reported with high frequency in patients with Jewish ancestry, and with low frequency in non-Jewish patients. This review will shed light on some updates regarding CD prevalence and causative mutations across the Arab World. CD was reported in several Arab countries such as Saudi Arabia, Egypt, Jordan, Yemen, Kuwait, and Tunisia. The population with the highest risk is in Saudi Arabia due the prevalent consanguineous marriage culture. In several studies, four novel mutations were found among Arabian CD patients, including two missense mutations (p.C152R, p.C152W), a 3346bp deletion leading to the removal of exon 3 of the ASPA gene, and an insertion mutation (698insC). Other previously reported mutations, which led to damage in the ASPA enzyme activities found among CD Arab patients are c.530 T>C (p.I177T), c.79G>A (p.G27R), IVS4+1G>T, and a 92kb deletion, which is 7.16kb upstream from the ASPA start site. This review will help in developing customized molecular diagnostic approaches and promoting CD carrier screening in the Arab world in areas where consanguineous marriage is common particularly within Saudi Arabia.

    Information is limited on alcohol use among Arab Americans. The purpose of this study was to describe and analyze the alcohol use pattern among Arab Americans by reviewing existing surveys using an acculturation model. Secondary data analysis. Nationally, English-speaking immigrant Arab Americans reported lower rates of lifetime alcohol use (50.8%), past month use (26.4%) and binge drinking (10%) than the White majority group. In a state survey, self-identified English-speaking Arab Americans were less likely to report past month use (45.6%) than the White majority group but reported similar rate of binge drinking (17.0%). Locally, lifetime drinking was reported by 46.2% of the immigrants but only 13.4% of refugees fleeing war. Few databases are available to estimate alcohol use pattern among Arab Americans; the limited data suggest a drinking pattern consistent with acculturation. However, the potential influence of other factors is unknown and needs to be investigated.

    This study examines contraceptive use among clients at the three clinics providing family planning services in Dakar, Senegal in early 1983. Most clients first became interested in family planning following the birth of a child, and most are interested in spacing future pregnancies, although one-third state that they want no more children. The clinic itself was found to be an important determinant of the type of contraceptive used, with only the government-operated clinic providing a balance between IUDs, oral contraceptives, and barrier methods. Nearly half of the clients interviewed said that a lack of knowledge about contraception is the reason for the low contraceptive prevalence rates among Senegalese women; another frequently cited reason was the opposition of the husband. Most clients reported the broadcast media to be the best means of providing family planning information to potential acceptors.

    English proficiency is associated with alcohol use in some immigrants groups, but little is known about its association among Arab Americans. Ethnographic work suggests gender, religion, education, and age influence prevalence of alcohol use among Arab Americans. Two years prospective study of recent Iraqi refugees and non-Iraqi Arab immigrants in Michigan using bilingual surveys and interviewers. At Time 1, prevalence of lifetime alcohol use was 20.5 % with males, Christians, better educated, older, and those with greater proficiency in English more likely to report ever drank. At Time 2, lifetime prevalence of drinking had increased to 34.0 %. In analysis of male new drinkers, risk factors were Christian, older age and greater proficiency in English. This study confirms drinking among recent immigrant Arab Americans varies by subgroups and suggests English proficiency may contribute to the increase in prevalence over time.

    Missal, Bernita

    2013-01-01

    This paper is a report of the findings of a study of Gulf Arab women's perspectives of the transition to motherhood. Transition to motherhood is a universal phenomenon in which every culture has its own expectations and varying supports for women moving through this transition. International studies have provided models or categories of maternal responses related to cultural aspects of transition to motherhood. However, no known research has focused on transition to motherhood among Gulf Arab women. In the initial cohort seventeen first time Gulf Arab mothers in the United Arab Emirates were interviewed during the following three times: before childbirth, two-four weeks after childbirth, and forty-days after childbirth. A second cohort of seventeen first time new mothers was interviewed after childbirth in Sultanate of Oman. Four patterns were identified as indicators of change as women transitioned into motherhood: 1) Women's personal transition: women changed from feeling of freedom to feeling of dependency to self-confidence. 2) Mother/baby relationships: women changed from fear, anxiety, and uncertainty to feelings of care and confidence. 3) Family influences: women experienced family support to being integrated and feeling respected by family. 4) Cultural/religious beliefs and practices: women felt they were initially observers of culture, to experiencing cultural/religious beliefs and practices. This was followed by accomplishment in childbearing and childrearing practices. As Gulf Arab new mothers made the transition to motherhood, four implications for international nursing practice emerged: 1) patient teaching to help relieve anxiety, fears, and uncertainty, 2) facilitation of mother/baby relationships, 3) family-centered care, and 4) the importance of cultural/religious beliefs and practices to new mothers.

    Men who have sex with men (MSM) are at high risk for HIV in Senegal, with a prevalence of 21.5%. In December 2008, nine male HIV prevention workers were imprisoned for “acts against nature” prohibited by Senegalese law. This qualitative study assessed the impact of these arrests on HIV prevention efforts. A purposive sample of MSM in six regions of Senegal was recruited by network referral. 26 in-depth interviews (IDIs) and 6 focus group discussions (FGDs) were conducted in July–August 2009. 14 key informants were also interviewed. All participants reported pervasive fear and hiding among MSM as a result of the December 2008 arrests and publicity. Service providers suspended HIV prevention work with MSM out of fear for their own safety. Those who continued to provide services noticed a sharp decline in MSM participation. An effective response to the HIV epidemic in Senegal should include active work to decrease enforcement of this law. PMID:22194906

    Background and Aims Thiophores, which are typically desert gypsophytes, accumulate high (2–6 % S dry weight) sulphur concentrations and may possess unique tolerance to environmental stress factors, e.g. sulphate/metal toxicity, drought and salinity. Little is known of the prevalence of the behaviour or the associated physiological aspects. The aim of this study was to (a) determine the prevalence of thiophore behaviour in a group of Australian xerophytes; (b) identify elemental uptake/storage characteristics of these thiophores; and (c) determine whether the behaviour is constitutive or environmental. Methods The elemental composition of soils and the foliage of 11 species (seven genera) at a site in the Tanami Desert (NT, Australia) was compared and 13 additional Acacia species from other locations were examined for elevated calcium and sulphur concentrations and calcium–sulphur mineralization, thought to be particular to thiophores. Key Results Acacia bivenosa DC. and 11 closely related species were identified as thiophores that can accumulate high levels of sulphur (up to 3·2 %) and calcium (up to 6.8 %), but no thiophores were identified in other genera occupying the same habitat. This behaviour was observed in several populations from diverse habitats, from samples collected over three decades. It was also observed that these thiophores featured gypsum (CaSO4·2H2O) crystal druses that completely filled cells and vascular systems in their dried phyllode tissues. Conclusions The thiophores studied exhibit a tight coupling between sulphur and calcium uptake and storage, and apparently store these elements as inorganic salts within the cells of their foliage. Thiophore behaviour is a constitutive trait shared by closely related Acacia but is not highly prevalent within, nor exclusive to, xerophytes. Several of the newly identified thiophores occupy coastal or riparian habitats, suggesting that the evolutionary and ecophysiological explanations for this trait

    "The various studies focussing on human settlements in Senegal show that the share of population living in cities is ever increasing because of the massive and continuous flow from rural areas. The persistance of such migration trends from the country to cities deepens regional disparities, compounds the difficulties and cost of city management and development, specially in the case of Dakar, and runs counter to the goals of social and economic development plans.... The growing importance of such phenomena calls for the designing of corrective measures in favour of rural areas and small towns in order to settle rural populations and halt the inordinate and chaotic geographical growth of large cities. Failing this, development efforts may well be compromised." (SUMMARY IN ENG) excerpt

    Despite the high burden of cardiovascular diseases in Arab countries, little is known about cardiac rehabilitation (CR) delivery. This study assessed availability, and CR program characteristics in the Arab World, compared to Canada. A questionnaire incorporating items from 4 national / regional published CR program surveys was created for this cross-sectional study. The survey was emailed to all Arab CR program contacts that were identified through published studies, conference abstracts, a snowball sampling strategy, and other key informants from the 22 Arab countries. An online survey link was also emailed to all contacts in the Canadian Association of Cardiovascular Prevention and Rehabilitation directory. Descriptive statistics were used to describe all closed-ended items in the survey. All open-ended responses were coded using an interpretive-descriptive approach. Eight programs were identified in Arab countries, of which 5 (62.5 %) participated; 128 programs were identified in Canada, of which 39 (30.5%) participated. There was consistency in core components delivered in Arab countries and Canada; however, Arab programs more often delivered women-only classes. Lack of human resources was perceived as the greatest barrier to CR provision in all settings, with space also a barrier in Arab settings, and financial resources in Canada. The median number of patients served per program was 300 for Canada vs. 200 for Arab countries. Availability of CR programs in Arab countries is incredibly limited, despite the fact that most responses stemmed from high-income countries. Where available, CR programs in Arab countries appear to be delivered in a manner consistent with Canada.

    2012-01-01

    We explored the eating habits of Arab immigrants to determine whether they have maintained their traditional diet or have consumed a more Westernized diet since immigrating to Canada. Arab immigrants who had been in Canada for at least eight years and were currently living in the Greater Toronto Area were recruited. A sample of 24 Arab immigrants completed a mailed, self-administered questionnaire, and six participated in a focus group. The focus group discussion was transcribed verbatim and results were recorded. Latent content analysis was used to analyze, code, and categorize emerging themes. Arab immigrants consumed a mixture of both Arabic and Western food and perceived their current diet to be healthier than it was before they immigrated to Canada. Factors that influenced their food choices included increased nutrition health awareness, differences in food preferences and preparation methods, and preservation of dietary practices in the new environment. Our findings will help dietitians who work with Arab immigrants to become more aware of factors that motivate this group's food choices, and to create nutrition programs that are more culturally sensitive.

  14. Colorimetric Detection Based on Localised Surface Plasmon Resonance Optical Characteristics for the Detection of Hydrogen Peroxide Using Acacia Gum–Stabilised Silver Nanoparticles

    The use of nanoparticles in sensing is attracting the interest of many researchers. The aim of this work was to fabricate Acacia gum–stabilised silver nanoparticles (SNPs) using green chemistry to use them as a highly sensitive and cost-effective localised surface plasmon resonance (LSPR) colorimeter sensor for the determination of reactive oxygen species, such as hydrogen peroxide (H2O2). Silver nanoparticles were fabricated by the reduction of an inorganic precursor silver nitrate solution (AgNO3) using white sugar as the reducing reagent and Acacia gum as the stabilising reagent and a sonication bath to form uniform silver nanoparticles. The fabricated nanoparticles were characterised by visual observation, ultraviolet-visible (UV-Vis) spectrophotometry, transmission electron microscopy (TEM) analysis, energy-dispersive X-ray spectroscopy (EDAX), thermogravimetric analysis (TGA), and Fourier transform infrared spectroscopy (FT-IR). The TEM micrographs of the synthesised nanoparticles showed the presence of spherical nanoparticles with sizes of approximately 10 nm. The EDAX spectrum result confirmed the presence of silver (58%), carbon (30%), and oxygen (12%). Plasmon colorimetric sensing of H2O2 solution was investigated by introducing H2O2 solution into Acacia gum–capped SNP dispersion, and the change in the LSPR band in the UV-Vis region of spectra was monitored. In this study, it was found that the yellow colour of Acacia gum–stabilised SNPs gradually changed to transparent, and moreover, a remarkable change in the LSPR absorbance strength was observed. The calibration curve was linear over 0.1–0.00001 M H2O2, with a correlation estimation (R2) of .953. This was due to the aggregation of SNPs following introduction of the H2O2 solution. Furthermore, the fabricated SNPs were successfully used to detect H2O2 solution in a liquid milk sample, thereby demonstrating the ability of the fabricated SNPs to detect H2O2 solution in liquid milk samples.

    Diabetes mellitus is an emerging epidemic in the Arab world. Although high diabetes prevalence is documented in Israeli Arabs, information from cohort studies is scant. This is a population study, based on information derived between 2007-2011, from the electronic database of the largest health fund in Israel, among Arabs and Jews. Prevalence, 4-year-incidence and diabetes hazard ratios [HRs], adjusted for sex and the metabolic-syndrome [MetS]-components, were determined in 3 age groups (<50 years, 50-59 years, and ≥60 years). The study cohort included 17,044 Arabs (males: 49%, age: 39.4±17.3) and 16,012 Jews (males: 50%, age: 40.5 ±17.6). The overall age and sex-adjusted diabetes prevalence rates were much higher among Arabs 18.4% (95%CI: 17.6-19.1); and 10.3% (95%CI: 9.7-10.9) among Jews. Arab females had higher prevalence rates 20.0% (95%CI: 19-21) than Arab males 16.7% (95%CI: 15.7-17.8). Annual incidence rates were also significantly higher among Arabs 2.9% (95%CI: 2.7-3.1) than among Jews 1.7% (95%CI: 1.6-1.8). This held true across all age and sex subgroups. Adjustment for body mass index [BMI] attenuated HR estimates associated with Arab ethnicity across all age subgroups, mainly in the <50yrs age group from HR 2.04 (95%CI: 1.74-2.40) to 1.64 (95%CI: 1.40-1.92). BMI at incident diabetes among females was higher in Arabs than Jews. Males, however, did not differ by ethnicity. Arabs, mainly female, have high incidence and prevalence of diabetes. This excess risk is only partially explained by the high prevalence of obesity. Effective culturally-congruent diabetes prevention and treatment and an effective engagement partnership with the Arab community are of paramount need.

    Progress towards reducing mortality and malnutrition among children <5 years of age has been less than needed to achieve related Millennium Development Goals (MDGs). Therefore, several international agencies joined to 'Reposition children's right to adequate nutrition in the Sahel', starting with an analysis of current activities related to infant and young child nutrition (IYCN). The main objectives of the situational analysis are to compile, analyse and interpret available information on infant and child feeding and the nutrition situation of children <2 years of age in Senegal, as one of the six targeted countries. These findings will be used to assist in identifying inconsistencies and filling gaps in current programming. Between August and December 2008, key informants responsible for conducting IYCN-related activities in Senegal were interviewed, and 157 documents were examined on the following themes: optimal breastfeeding and complementary feeding practices, prevention of micronutrient deficiencies, prevention of mother-to-child transmission of HIV, management of acute malnutrition, food security and hygienic practices. Nearly all of the key IYCN topics were addressed, specifically or generally, in national policy documents. Senegal reported substantial improvements since the 1990s towards reducing infant and young child mortality and underweight, and increasing exclusive breastfeeding among infants <6 months of age (34%). Senegal is one of the few countries in the region that is nearly on track for reaching related MDGs. Notable activities that may have played a role include: (1) vitamin A supplementation was expanded to nearly semi-annual national campaigns starting in 1994; (2) the Ministry of Health partnered with several national and international agencies to scale up child survival activities under the umbrella of the Basic Support for Institutionalizing Child Survival (1994-2006); (3) a national nutrition division was developed to support a national

    Allergic rhinitis (AR) is a common inflammation of the nasal mucosa in response to allergen exposure. We translated and validated the Score for Allergic Rhinitis (SFAR) into an Arabic version so that the disease can be studied in an Arabic population. SFAR is a non-invasive self-administered tool that evaluates eight items related to AR. This study aimed to translate and culturally adapt the SFAR questionnaire into Arabic, and assess the validity, consistency, and reliability of the translated version in an Arabic-speaking population of patients with suspected AR. Cross-sectional. Tertiary care hospital in Riyadh. The Arabic version of the SFAR was administered to patients with suspected AR and control participants. Comparison of the AR and control groups to determine the test-retest reliability and internal consistency of the instrument. The AR (n=173) and control (n=75) groups had significantly different Arabic SFAR scores (P < .0001). The instrument provided satisfactory internal consistency (Cronbach's alpha value of 0.7). The test-retest reliability was excellent for the total Arabic SFAR score (r =0.836, P < .0001). These findings demonstrate that the Arabic version of the SFAR is a valid tool that can be used to screen Arabic speakers with suspected AR. The absence of objective allergy testing.

    INTRODUCTION English proficiency is associated with alcohol use in some immigrants groups, but little is known about its association among Arab Americans. Ethnographic work suggests gender, religion, education, and age influence prevalence of alcohol use among Arab Americans. METHODS Two year prospective study of recent Iraqi refugees and non-Iraqi Arab immigrants in Michigan using bilingual surveys and interviewers. RESULTS At Time 1, prevalence of lifetime alcohol use was 20.5% with males, Christians, better educated, older, and those with greater proficiency in English more likely to report ever drank. At Time 2, lifetime prevalence of drinking had increased to 34.0%. In analysis of male new drinkers, risk factors were Christian, older age and greater proficiency in English. DISCUSSION This study confirms drinking among recent immigrant Arab Americans varies by subgroups and suggests English proficiency may contribute to the increase in prevalence over time.

    This article analyses the research output of a sample of higher education institutions (HEIs) in six Arab countries in order to start quantifying academic research productivity in the wider region of the Middle East and North Africa (MENA). A questionnaire classifying HEIs was administered to 310 institutions in Lebanon, Qatar, the United Arab Emirates (UAE), Morocco, Saudi Arabia and Jordan. The study revealed a lack of capacity of HEIs to provide quality data, raising issues concerning institutional excellence and transparency. Those data which were available were analysed using a number of statistical methods. The result is that faculty research output in the Arab world is relatively low, confirming the existing notion of a lagging knowledge sector in the region. While traditional scholarship has focused on institutional factors such as budgetary allocation as one prime determinant of research productivity, this study claims that other factors need to be considered in explaining the low output, with broad implications for policy formulation. Such factors include overall satisfaction levels of academic staff, socialisation of faculty staff members into a research climate, and university mission vis-à-vis academic research. Given the distinct paucity of studies on faculty research productivity in HEIs in the Arab region, this study seeks to bridge this gap in the literature by providing original data derived from six Arab countries. The authors aim to provide a basis for further research into this topic.

    Background The present paper deals with the relationship between health indicators and human development in the Arab region. Beyond descriptive analysis showing geographic similarities and disparities inter countries, the main purpose is to point out health deficiencies and to propose pragmatic strategies susceptible to improve health conditions and consequently enhance human development in the Arab world. Methods Data analysis using Principal Components Analysis is used to compare the achievements of the Arab countries in terms of direct and indirect health indicators. The variables (indicators) are seen to be well represented on the circle of correlation, allowing for interesting interpretation and analysis. The 19 countries are projected on the first and second plane respectively. Results The results given by the present analysis give a good panorama of the Arab countries with their geographic similarities and disparities. The high correlation between health indicators and human development is well illustrated and consequently, countries are classified by groups having similar human development. The analysis shows clearly how health deficits are impeding human development in the majority of Arab countries and allows us to formulate suggestions to improve health conditions and enhance human development in the Arab World. Discussion The discussion is based on the link between different direct and indirect health indicators and the relationship between these indicators and human development index. Without including the GDP indicator, our analysis has shown that the 19 Arab countries may be classified, independently of their geographic proximity, in three different groups according to their global human development level (Low, Medium and High). Consequently, while identifying health deficiencies in each group, the focus was made on the countries presenting a high potential of improvement in health indicators. In particular, maternal mortality and infant mortality

    Sentiment analysis has become a flourishing field of text mining and natural language processing. Sentiment analysis aims to determine whether the text is written to express positive, negative, or neutral emotions about a certain domain. Most sentiment analysis researchers focus on English texts, with very limited resources available for other complex languages, such as Arabic. In this study, the target was to develop an initial model that performs satisfactorily and measures Arabic Twitter sentiment by using machine learning approach, Naïve Bayes and Decision Tree for classification algorithms. The datasets used contains more than 2,000 Arabic tweets collected from Twitter. We performed several experiments to check the performance of the two algorithms classifiers using different combinations of text-processing functions. We found that available facilities for Arabic text processing need to be made from scratch or improved to develop accurate classifiers. The small functionalities developed by us in a Python language environment helped improve the results and proved that sentiment analysis in the Arabic domain needs lot of work on the lexicon side.

    Vitamin D plays a critical role in bone metabolism and many cellular and immunological processes. Low levels of vitamin D have been associated with various chronic diseases especially rickets in children and osteoporosis in adults. Adequate vitamin D intake is of paramount importance to protect against bone metabolic diseases and prevent the occurrence of complications (e. g., fracture and bone pains). This study aimed at the evaluation of vitamin D levels in a cohort of healthy Saudi Arabs. The comprised 139 healthy subjects coming for regular blood donation. Participants had full clinical examination and evaluation of their calcium and vitamin D intake and the degree of exposure to sunlight. Serum 25-OH vitamin D was determined using Liasion chemiluminescent immunoassay and serum parathormone levels were determined using the Architect 2,000 immunochemiluminescent assay. Our results showed increased prevalence of vitamin D deficiency between Saudi Arabs (both males and females) in the studied group of subjects. Serum parathyroid hormone (PTH) did not correlate with serum vitamin D level in either male or female groups (p<0.01). Our data illustrate a high prevalence of vitamin D deficiency between Saudi Arabs and the importance for screening for vitamin D deficiency (irrespective of PTH level). We hypothesize that the reported vitamin D deficiency in the studied group of Saudi Arabs may reflect a possible inadequacy of the current level of vitamin D fortification of food products. We suggest that higher level of fortification of food products with vitamin D may be needed to compensate for the reduced skin vitamin D synthesis due to poor exposure to sunlight and to reverse this state of vitamin D deficiency in Saudi Arabs.

    Kuwait has a cosmopolitan population of 1.7 million, mostly Arabs. This population is a mosaic of large and small minorities representing most Arab communities. In general, Kuwait's population is characterized by a rapid rate of growth, large family size, high rates of consanguineous marriages within the Arab communities with low frequency of intermarriage between them, and the presence of genetic isolates and semi-isolates in some extended families and Bedouin tribes. Genetic services have been available in Kuwait for over a decade. During this time it has become clear that Arabs have a high frequency of genetic disorders, and in particular autosomal recessive traits. Their pattern is unique and some disorders are relatively common. Examples are Bardet-Biedl and Meckel syndromes, phenylketonuria, and familial Mediterranean fever. A relatively large number of new syndromes and variants have been delineated in Kuwait's population, many being the result of homozygosity for autosomal recessive genes that occurred because of inbreeding. Some of these syndromes have subsequently been found in other parts of the world, negating the concept of the private syndrome. This paper provides an overview of autosomal recessive disorders among the Arabs in Kuwait from a personal perspective and published studies, and highlights the need for genetic services in Arab countries with the goal of prevention and treatment of genetic disorders.

    One billion of the world’s population has hypertension, resulting in four million deaths per year. Data on the prevalence of hypertension in the Arab world are very limited. This review summarizes existing knowledge regarding prevalence, awareness, and control of hypertension in Arab countries. The PubMed, Cochrane Library, Scopus, and CINAHL databases were searched for publications on HTN among Arab people from 1980 to January 2011. Only 13 studies were identified in the literature from 10 Arab countries. The overall estimated prevalence of hypertension was 29.5% (n = 45 379), which indicates a higher prevalence of hypertension among Arabs compared to people from the USA (28%) and sub-Saharan African (27.6%). Awareness of hypertension was reported for 46% of the studies and varied from 18% (Jordan) to 79.8% (Syria). The control rate varied from 56% (Tunisia) to 92% (Egypt and Syria). The prevalence of hypertension was found to increase with age, occurring more frequently in Arab women. PMID:24118852

Clinical measurement study. Tertiary care center. The original English THI was translated into literary Arabic by a forward- and back-translation process according to the published guidelines for cross-cultural adaptation of health-related quality-of-life measures and applied to 100 patients with chronic tinnitus. Internal consistency reliability was then assessed by calculating Cronbach's alpha coefficient. Pearson correlation coefficients were also calculated for the different scales and the different baseline characteristics. Results showed high internal consistency and reliability coefficients (total THI: 0.93, functional subscale: 0.86, emotional subscale: 0.86, catastrophic subscale: 0.66) comparable to those of the original English THI. The Arabic version of the THI is a valid and reliable tool for the assessment of the impact of tinnitus on the quality of life of Arabic-speaking patients with the complaint of chronic tinnitus. © American Academy of Otolaryngology—Head and Neck Surgery Foundation 2015.

    Arab Americans have a high burden of diabetes and poor outcomes compared to the general U.S. Diabetes self-management (DSM) requires a partnership between patients and providers that fosters mutual understanding and shared decision-making. Cultural factors influence this process; however, little is known regarding the cultural impact on DSM or if perceptions differ between patients and providers. Qualitative content analysis was used to analyze five focus groups-two groups with Arab American providers (n = 8) and three groups with adult Arab Americans with diabetes (n = 23). Focus groups examined patient and provider perspectives on the meaning of DSM and cultural barriers and facilitators among Arab American patients. Four distinct themes included limited resources for DSM education and support, stigma as a barrier to ongoing support, family support as an opportunity and challenge, and Arab American patient-provider relationships. Findings indicate several domains should be considered for clinical practice including a need to develop linguistically and culturally reliant educational materials and relevant supports for use in the Arab American population. Findings highlight differing views among providers and patients on the familial role in supporting DSM efforts and why some patients feel dissatisfied with clinical encounters.

    Stroke is second only to ischaemic heart disease as a cause of death, and over a third of stroke deaths occur in developing countries. Arab countries constitute populations with a similar lifestyle and diet that may influence stroke risk, type and survival after stroke, as well as other characteristics in comparison to Western and Oriental populations. Therefore, a review of published reports of stroke in Arab countries was undertaken to provide a background for designing future stroke studies in Arab populations. Thirty-one articles related to incidence, prevalence, types, risk factors and outcome of stroke in Arab countries were identified by keyword searching of Medline and Embase, and review of references in all relevant papers. Studies were available for Saudi Arabia (n=16), Qatar (n=4), Libya (n=3), Kuwait (n=2), Jordan (n=1), United Arab Emirates (n=1), Bahrain (n=1), Tunisia (n=1), Iraq (n=1), and Sudan (n=1). The publication dates ranged from 1983-2008. The annual stroke incidence ranged from 27.5 to 63 per 100,000 population and prevalence was between 42 and 68 per 100,000 population. Ischaemic stroke was the commonest subtype in all series. However, one series from Sudan had a 41% rate of intracerebral haemorrhage, which is more similar to East Asian countries. Non-lacunar infarction occurred more frequently than lacunar infarcts in all but two series. Hypertension, diabetes mellitus, hyperlipidaemia, and cardiac disease were the commonest risk factors. The case-fatality rate at 30 days was between 10 and 17.5%. Therefore, the incidence and prevalence of stroke in Arab countries are lower than the Western world but within the range reported in Chinese populations. Stroke types and risk factors are similar, but an apparently higher rate of lacunar infarction in some settings needs further investigation. There is therefore a significant opportunity for further evaluation of stroke in Arab countries, especially in unstudied areas such as the populous

    Climate change is predicted to impact species' genetic diversity and distribution. We used Senegalia senegal (L.) Britton, an economically important species distributed in the Sudano-Sahelian savannah belt of West Africa, to investigate the impact of climate change on intraspecific genetic diversity and distribution. We used ten nuclear and two plastid microsatellite markers to assess genetic variation, population structure and differentiation across thirteen sites in West Africa. We projected suitable range, and potential impact of climate change on genetic diversity using a maximum entropy approach, under four different climate change scenarios. We found higher genetic and haplotype diversity at both nuclear and plastid markers than previously reported. Genetic differentiation was strong for chloroplast and moderate for the nuclear genome. Both genomes indicated three spatially structured genetic groups. The distribution of Senegalia senegal is strongly correlated with extractable nitrogen, coarse fragments, soil organic carbon stock, precipitation of warmest and coldest quarter and mean temperature of driest quarter. We predicted 40.96 to 6.34 per cent of the current distribution to favourably support the species' ecological requirements under future climate scenarios. Our results suggest that climate change is going to affect the population genetic structure of Senegalia senegal, and that patterns of genetic diversity are going to influence the species' adaptive response to climate change. Our study contributes to the growing evidence predicting the loss of economically relevant plants in West Africa in the next decades due to climate change.

The distribution of Senegalia senegal is strongly correlated with extractable nitrogen, coarse fragments, soil organic carbon stock, precipitation of warmest and coldest quarter and mean temperature of driest quarter. We predicted 40.96 to 6.34 per cent of the current distribution to favourably support the species’ ecological requirements under future climate scenarios. Our results suggest that climate change is going to affect the population genetic structure of Senegalia senegal, and that patterns of genetic diversity are going to influence the species’ adaptive response to climate change. Our study contributes to the growing evidence predicting the loss of economically relevant plants in West Africa in the next decades due to climate change. PMID:29659603

  14. Larval ecology of mosquitoes in sylvatic arbovirus foci in southeastern Senegal

    PubMed Central

    2012-01-01

    Background Although adult mosquito vectors of sylvatic arbovirus [yellow fever (YFV), dengue-2 (DENV-2) and chikungunya (CHIKV)] have been studied for the past 40 years in southeastern Senegal, data are still lacking on the ecology of larval mosquitoes in this area. In this study, we investigated the larval habitats of mosquitoes and characterized their seasonal and spatial dynamics in arbovirus foci. Methods We searched for wet microhabitats, classified in 9 categories, in five land cover classes (agriculture, forest, savannah, barren and village) from June, 2010 to January, 2011. Mosquito immatures were sampled monthly in up to 30 microhabitats of each category per land cover and bred until adult stage for determination. Results No wet microhabitats were found in the agricultural sites; in the remaining land covers immature stages of 35 mosquito species in 7 genera were sampled from 9 microhabitats (tree holes, fresh fruit husks, decaying fruit husks, puddles, bamboo holes, discarded containers, tires, rock holes and storage containers). The most abundant species was Aedes aegypti formosus, representing 30.2% of the collections, followed by 12 species, representing each more than 1% of the total, among them the arbovirus vectors Ae. vittatus (7.9%), Ae. luteocephalus (5.7%), Ae. taylori (5.0%), and Ae. furcifer (1.3%). Aedes aegypti, Cx. nebulosus, Cx. perfuscus, Cx. tritaeniorhynchus, Er. chrysogster and Ae. vittatus were the only common species collected from all land covers. Aedes furcifer and Ae. taylori were collected in fresh fruit husks and tree holes. Species richness and dominance varied significantly in land covers and microhabitats. Positive associations were found mainly between Ae. furcifer, Ae. taylori and Ae. luteocephalus. A high proportion of potential enzootic vectors that are not anthropophilic were found in the larval mosquito fauna. Conclusions In southeastern Senegal, Ae. furcifer and Ae. taylori larvae showed a more limited distribution

  15. Rasch validation of the Arabic version of the lower extremity functional scale.

    2018-02-01

    The purpose of this study was to examine the internal construct validity of the Arabic version of the Lower Extremity Functional Scale (20-item Arabic LEFS) using Rasch analysis. Patients (n = 170) with lower extremity musculoskeletal dysfunction were recruited. Rasch analysis of 20-item Arabic LEFS was performed. Once the initial Rasch analysis indicated that the 20-item Arabic LEFS did not fit the Rasch model, follow-up analyses were conducted to improve the fit of the scale to the Rasch measurement model. These modifications included removing misfitting individuals, changing item scoring structure, removing misfitting items, addressing bias caused by response dependency between items and differential item functioning (DIF). Initial analysis indicated deviation of the 20-item Arabic LEFS from the Rasch model. Disordered thresholds in eight items and response dependency between six items were detected with the scale as a whole did not meet the requirement of unidimensionality. Refinements led to a 15-item Arabic LEFS that demonstrated excellent internal consistency (person separation index [PSI] = 0.92) and satisfied all the requirement of the Rasch model. Rasch analysis did not support the 20-item Arabic LEFS as a unidimensional measure of lower extremity function. The refined 15-item Arabic LEFS met all the requirement of the Rasch model and hence is a valid objective measure of lower extremity function. The Rasch-validated 15-item Arabic LEFS needs to be further tested in an independent sample to confirm its fit to the Rasch measurement model. Implications for Rehabilitation The validity of the 20-item Arabic Lower Extremity Functional Scale to measure lower extremity function is not supported. The 15-item Arabic version of the LEFS is a valid measure of lower extremity function and can be used to quantify lower extremity function in patients with lower extremity musculoskeletal disorders.

    Objective Diabetes mellitus is an emerging epidemic in the Arab world. Although high diabetes prevalence is documented in Israeli Arabs, information from cohort studies is scant. Methods This is a population study, based on information derived between 2007–2011, from the electronic database of the largest health fund in Israel, among Arabs and Jews. Prevalence, 4-year-incidence and diabetes hazard ratios [HRs], adjusted for sex and the metabolic-syndrome [MetS]-components, were determined in 3 age groups (<50 years, 50–59 years, and ≥60 years). Results The study cohort included 17,044 Arabs (males: 49%, age: 39.4±17.3) and 16,012 Jews (males: 50%, age: 40.5 ±17.6). The overall age and sex-adjusted diabetes prevalence rates were much higher among Arabs 18.4% (95%CI: 17.6–19.1); and 10.3% (95%CI: 9.7–10.9) among Jews. Arab females had higher prevalence rates 20.0% (95%CI: 19–21) than Arab males 16.7% (95%CI: 15.7–17.8). Annual incidence rates were also significantly higher among Arabs 2.9% (95%CI: 2.7–3.1) than among Jews 1.7% (95%CI: 1.6–1.8). This held true across all age and sex subgroups. Adjustment for body mass index [BMI] attenuated HR estimates associated with Arab ethnicity across all age subgroups, mainly in the <50yrs age group from HR 2.04 (95%CI: 1.74–2.40) to 1.64 (95%CI: 1.40–1.92). BMI at incident diabetes among females was higher in Arabs than Jews. Males, however, did not differ by ethnicity. Conclusion Arabs, mainly female, have high incidence and prevalence of diabetes. This excess risk is only partially explained by the high prevalence of obesity. Effective culturally-congruent diabetes prevention and treatment and an effective engagement partnership with the Arab community are of paramount need. PMID:28481942

  17. Arab petrodollars: dashed hope for a new economic order

    Gauhar, A.

    The North-South debate is currently quiescent, partly because Arab oil producers have failed to provide long-term support for Third World concerns. The author examines why the oil producers have abandoned the call for a New International Economic Order, and concludes that the key to understanding this missed opportunity is in the manner in which the oil-producing countries, particularly the Arab OPEC nations, deployed their income during the years of abundance. The Arab governments adopted a pattern of expenditure and investment that was clearly opposed to the interests and welfare of their own people for a variety of social and politicalmore » reasons. An important fact, which precluded cooperation among Third World countries, was the integrated nature of Arab financial capital within world capitalism.« less

  18. Do we access meaning when we name Arabic digits? Electrophysiological evidence.

    Macizo, Pedro; Álvarez, Alejandro

    2018-06-12

    In this study, we evaluated whether the naming of Arabic digits required access to semantic information. Participants named pictures and Arabic digits blocked by category or intermixed with exemplars of other categories while behavioural and electrophysiological measures were gathered. Pictures were named slower and Arabic digits faster in the blocked context relative to the mixed context. Around 350-450 ms after the presentation of pictures and Arabic digits, brain waves were more positive in anterior regions and more negative in posterior regions when the blocked context was compared with the mixed context. The pattern of electrophysiological results suggests that pictures and Arabic digits are both processed semantically and they are subject to repetition effects during the naming task. © 2018 The British Psychological Society.

    Arabic diacritics are often missed in Arabic scripts. This feature is a handicap for new learner to read َArabic, text to speech conversion systems, reading and semantic analysis of Arabic texts. The automatic diacritization systems are the best solution to handle this issue. But such automation needs resources as diactritized texts to train and evaluate such systems. In this paper, we describe our corpus of Arabic diacritized texts. This corpus is called Tashkeela. It can be used as a linguistic resource tool for natural language processing such as automatic diacritics systems, dis-ambiguity mechanism, features and data extraction. The corpus is freely available, it contains 75 million of fully vocalized words mainly 97 books from classical and modern Arabic language. The corpus is collected from manually vocalized texts using web crawling process.

    The Saudi decision during the October War to combine oil and politics and to relate the flow of Saudi oil to American Middle Eastern policies marked a major deviation from a long-standing policy. This has resulted in a major re-thinking of U.S. interests and long-range policies by U.S. policy makers toward all Arab national interests. The entanglement has forced U.S. policy makers to recognize three realities. First, Arab oil production can no longer be treated separately from Arab national issues, most particularly the Palestine problem. Second, smoothly functioning economic relationships will follow only if outstanding political conflicts are resolved; again,more » the Palestine conflict is the uppermost issue. Third, the U.S., as a major industrial country and as a superpower directly concerned with international peace and security, can no longer choose between one of only two traditional positions: complete detachment or total involvement; other options must be examined. In order to develop a policy framework for future American relations with the Arab littoral states of the Gulf, several dimensions are examined, namely: the political and ideological nature of the Arab regimes in the Gulf, the religious/tribal foundations of these regimes and the oil-generated affluence of their ruling families, the diplomatic and military activities of regional and other powers; and the new economic factors in the Gulf. The last chapter presents a long-range projection of American international relations in the Gulf and the spectrum of options available to U.S. policymakers. (MCW)« less

    PCR-based typing of the HLA-DQA1 locus, using allele specific oligonucleotide (ASO) probes and reverse dot blot methodology was used to determine allelic distributions and construct a database for Arab and Pakistani individuals living in Dubai. Genotype and allelic frequencies were calculated, and the data were tested for departures from Hardy-Weinberg (HWE) equilibrium. The most frequent HLA-DQA1 alleles among Dubaian Arabs are DQA1 4 and 1.2. Among Pakistanis, the most frequent allele is also DQA1 4. No significant deviations from HWE were detected.

    Considerable amounts of nitrogen (N) and phosphorus (P) fertilizers have been mis-used in agroecosystems, with profound alteration to the biogeochemical cycles of these two major nutrients. To reduce excess fertilizer use, plant-mediated nutrient supply through N(2)-fixation, transfer of fixed N and mobilization of soil P may be important processes for the nutrient economy of low-input tree-based intercropping systems. In this study, we quantified plant performance, P acquisition and belowground N transfer from the N(2)-fixing tree to the cereal crop under varying root contact intensity and P supplies. We cultivated Acacia senegal var senegal in pot-culture containing 90% sand and 10% vermiculite under 3 levels of exponentially supplied P. Acacia plants were then intercropped with durum wheat (Triticum turgidum durum) in the same pots with variable levels of adsorbed P or transplanted and intercropped with durum wheat in rhizoboxes excluding direct root contact on P-poor red Mediterranean soils. In pot-culture, wheat biomass and P content increased in relation to the P gradient. Strong isotopic evidence of belowground N transfer, based on the isotopic signature (δ(15)N) of tree foliage and wheat shoots, was systematically found under high P in pot-culture, with an average N transfer value of 14.0% of wheat total N after 21 days of contact between the two species. In the rhizoboxes, we observed limitations on growth and P uptake of intercropped wheat due to competitive effects on soil resources and minimal evidence of belowground N transfer of N from acacia to wheat. In this intercrop, specifically in pot-culture, facilitation for N transfer from the legume tree to the crop showed to be effective especially when crop N uptake was increased (or stimulated) as occurred under high P conditions and when competition was low. Understanding these processes is important to the nutrient economy and appropriate management of legume-based agroforestry systems. Copyright

    The Child Abuse Potential Inventory (CAPI) is a well-validated screening tool for assessing potential for child physical abuse, and has been translated into many different languages. To date the CAPI has not been translated into Arabic or used in any studies in Arabic-speaking populations. This study reports on the process of adapting the CAPI into Arabic Language which was undertaken following the International Society of Pharma-economics and Outcomes Research (ISPOR) guidelines. The translation/adaptation process was multi-stage, and involved the use of a Delphi process, cognitive debriefing, back translation, and a pilot testing of the Arabic CAPI at two primary health care centers with a population of pregnant women (n=60). Following "literal translation" 73 out of the 160 items needed re-phrasing to adapt the items to the Oman context. No differences were found when comparing results of the translated or back-translated versions to source; however, eight items needed further amendment following translated to back-translated comparison and feedback from the pilot. Iterations were resolved following in-depth interviews. Discrepancies were due to differences in culture, parenting practices, and religion. Piloting of the tool indicated mean score value of 155.8 (SD=59.4) and eleven women (18%) scored above the cut off value of 215. This Arabic translation of the CAPI was undertaken using rigorous methodology and sets the scene for further research on the Arabic CAPI within Arabic-speaking populations.

    As effective onchocerciasis control efforts in Africa transition to elimination efforts, different diagnostic tools are required to support country programs. Senegal, with its long standing, successful control program, is transitioning to using the SD BIOLINE Onchocerciasis IgG4 (Ov16) rapid test over traditional skin snip microscopy. The aim of this study is to demonstrate the feasibility of integrating the Ov16 rapid test into onchocerciasis surveillance activities in Senegal, based on the following attributes of acceptability, usability, and cost. A cross-sectional study was conducted in 13 villages in southeastern Senegal in May 2016. Individuals 5 years and older were invited to participate in a demographic questionnaire, an Ov16 rapid test, a skin snip biopsy, and an acceptability interview. Rapid test technicians were interviewed and a costing analysis was conducted. Of 1,173 participants, 1,169 (99.7%) agreed to the rapid test while 383 (32.7%) agreed to skin snip microscopy. The sero-positivity rate of the rapid test among those tested was 2.6% with zero positives 10 years and younger. None of the 383 skin snips were positive for Ov microfilaria. Community members appreciated that the rapid test was performed quickly, was not painful, and provided reliable results. The total costs for this surveillance activity was $22,272.83, with a cost per test conducted at $3.14 for rapid test, $7.58 for skin snip microscopy, and $13.43 for shared costs. If no participants had refused skin snip microscopy, the total cost per method with shared costs would have been around $16 per person tested. In this area with low onchocerciasis sero-positivity, there was high acceptability and perceived value of the rapid test by community members and technicians. This study provides evidence of the feasibility of implementing the Ov16 rapid test in Senegal and may be informative to other country programs transitioning to Ov16 serologic tools.

    2012-01-01

    After a brief review of the proliferation of newly coined Arabic words to speak about LGBTQIA (lesbian, gay, bisexual, transgender, queer, intersex, and ally) identities, this article interrogates the facile imitation of Western labels and questions their usefulness in the context of Arab societies and cultures. It demonstrates that the assumptions that underlie the creation of new wordlists overlook and ultimately erase the very rich tradition on alternative sexual practices that has been prominent in the Islamicate world at least since the ninth century. Salvaging this tradition and its accompanying terminology on homosexuality challenges the claim that homosexuality is a Western importation, and renders the recourse to English categories superfluous. Moreover, uncovering the forgotten Arabic cultural material on alternative sexualities offers contemporary Arab gays and lesbians a rich and empowering indigenous heritage, as well as home-grown modes of resistance that are poised to challenge homophobic attitudes and policies in the Arab world, and the hegemony of Western sexual and cultural imperialism.

    2014-10-01

    The present work deals with development of modified gum arabic cross-linked gelatin scaffold for cell culture. A new biocompatible scaffold was developed by cross-linking gelatin (Gel) with gum arabic, a polysaccharide. Gum arabic was subjected to periodate oxidation to obtain gum arabic aldehyde (GAA). GAA was reacted with gelatin under appropriate pH to prepare the cross-linked hydrogel. Cross-linking occurred due to Schiff's base reaction between aldehyde groups of oxidized gum arabic and amino groups of gelatin. The scaffold prepared from the hydrogel was characterized by swelling properties, degree of cross-linking, in vitro degradation and scanning electron microscopy (SEM). Cytocompatibility evaluation using L-929 and HepG2 cells confirmed non-cytotoxic and non-adherent nature of the scaffold. These properties are essential for generating multicellular spheroids and hence the scaffold is proposed to be a suitable candidate for spheroid cell culture. Copyright © 2014 Elsevier B.V.

    Thaumatin is a sweetener and flavor modifier commonly used in the food industry. Likewise, gum arabic is widely used as a food stabilizer and thickening agent. We report here that a powder mixture composed of 10% thaumatin and 90% gum arabic led to allergic symptoms in the upper airways in occupationally exposed individuals: four of eight workers of a chewing gum factory exposed to this powder mixture had pronounced rhinitis. A positive skin prick test result for pure thaumatin was obtained in all four individuals with rhinitis of whom two also had a positive skin prick test result for pure gum arabic and gum arabic-specific IgE. Subsitution of a powdered thaumatin with a liquid form reduced symptoms among the rhinitic workers. Although gum arabic is a well-known potential allergen, we were unable to find prior documentation of allergic symptoms to thaumatin when it is used in the food industry. © 2017 Wiley Periodicals, Inc.

    A medico-ethnobotanical survey was conducted among the Senegalese migrant communities of Turin (Piedmont, NW Italy) and their peers living in Adeane (Casamance, Southern Senegal), both among healers and laypeople. Through 27 in-depth interviews, 71 medicinal plant taxa were recorded and identified in Adeane and 41 in Turin, for a total of 315 different folk remedies recorded in Senegal and 62 in Turin. The large majority of the medicinal plants recorded among Senegalese migrants in Turin were also used in their country of origin. These findings demonstrate the resilience of home remedies among migrants and consequently the role they should have in shaping public health policies devoted to migrant groups in Western Countries, which seek to seriously take into account culturally sensitive approaches, that is, emic health-seeking strategies.

    The Arab world, which consists of the 22 member states of the Arab League, is undergoing a rapid transition in demographics, including fertility, mortality, and migration. Comprising a distinctive geographic region spread across West Asia and North East Africa and unified by the Arabic language, these states share common values and characteristics despite having diverse economic and political conditions. The demographic lag (high fertility and low mortality) that characterizes the Arab world is unique, but the present trend of declining fertility, combined with the relatively low mortality, brings about significant changes in its population size. This research aimed to: (i) assess the population growth in the Arab world over 3 time periods, (ii) explore its components, and (iii) understand its public health impact. Data from the International Data Base (IDB) of the U.S. Census Bureau for 3 time periods (1992, 2002, and 2012) in 21 countries of the Arab world were analyzed by dividing them into four geographic sectors, namely, the Gulf Cooperation Council (GCC), West Asia, Maghreb, and the Nile Valley African Horn. The population of the Arab world has grown considerably due to both natural growth and migration. The immigration is pronounced, especially into resource-intensive GCC nations, not only from East Asian and Central African countries but also from resource-thrifty (limited-resource) Arab nations. The migrations within, as well as outside, the Arab world reveal an interesting demographic phenomenon that requires further research: migration flows and trends. However, the transformations in public health statistics related to mortality—the impact of demographic changes—depict a new era in the Arab world. PMID:25993053

    Despite the existing knowledge on the association between discrimination and poor mental health, very few studies have explored gender differences in this association in Arab Americans. The current study aimed to investigate whether gender moderates the association between the experience of discrimination and psychological distress in a representative sample of Arab Americans in Michigan. Using data from the Detroit Arab American Study (DAAS), 2003, this study recruited Arab Americans (337 males, 385 females) living in Michigan, United States. The main independent variable was discrimination. The main outcome was psychological distress. Covariates included demographic factors (age), socioeconomic status (education, employment, and income), and immigration characteristics (nativity and years living in United States). Gender was the focal moderator. We used multivariable regression with and without discrimination × gender interaction term. In the pooled sample, discrimination was positively associated with psychological distress [ B  = 0.62, 95% confidence interval (CI) = 0.22-1.03, p  = 0.003]. We found a significant gender × discrimination interaction in the pooled sample ( B  = 0.79, 95% CI = 0.01-1.59, p  = 0.050), suggesting a stronger association in males than females. In our gender-specific model, higher discrimination was associated with higher psychological distress among male ( B  = 0.87, 95% CI = 0.33-1.42, p  = 0.002) but not female ( B  = 0.18, 95% CI = -0.43 to 0.78, p  = 0.567) Arab Americans. While discrimination is associated with poor mental health, a stronger link between discrimination and psychological symptoms may exist in male compared to female Arab Americans. While efforts should be made to universally reduce discrimination, screening for discrimination may be a more salient component of mental health care for male than female Arab Americans.

    Schistosomiasis is a parasitic, water-related disease that is prevalent in tropical and subtropical areas of the world, causing severe and chronic consequences especially among children. Here we study the spatial spread of this disease within a network of connected villages in the endemic region of the Lower Basin of the Senegal River, in Senegal. The analysis is performed by means of a spatially explicit metapopulation model that couples local-scale eco-epidemiological dynamics with spatial mechanisms related to human mobility (estimated from anonymized mobile phone records), snail dispersal and hydrological transport of schistosome larvae along the main water bodies of the region. Results show that the model produces epidemiological patterns consistent with field observations, and point out the key role of spatial connectivity on the spread of the disease. These findings underline the importance of considering different transport pathways in order to elaborate disease control strategies that can be effective within a network of connected populations.

    The 2014-2015 epidemic of Ebola virus disease in West Africa primarily affected Guinea, Liberia, and Sierra Leone. Several countries, including Mali, Nigeria, and Senegal, experienced Ebola importations. Realizing the importance of a trained field epidemiology workforce in neighboring countries to respond to Ebola importations, the Centers for Disease Control and Prevention Field Epidemiology Training Program unit implemented the Surveillance Training for Ebola Preparedness (STEP) initiative. STEP was a mentored, competency-based initiative to rapidly build up surveillance capacity along the borders of the at-risk neighboring countries Côte d'Ivoire, Mali, Senegal, and Guinea-Bissau. The target audience was district surveillance officers. STEP was delivered to 185 participants from 72 health units (districts or regions). Timeliness of reporting and the quality of surveillance analyses improved 3 months after training. STEP demonstrated that mentored, competency-based training, where learners attain competencies while delivering essential public health services, can be successfully implemented in an emergency response setting.

  11. Obesity in Arabic-Speaking Countries

    2011-01-01

    Obesity has reached epidemic proportions throughout the globe, and this has also impacted people of the Arabic-speaking countries, especially those in higher-income, oil-producing countries. The prevalence of obesity in children and adolescents ranges from 5% to 14% in males and from 3% to 18% in females. There is a significant increase in the incidence of obesity with a prevalence of 2%–55% in adult females and 1%–30% in adult males. Changes in food consumption, socioeconomic and demographic factors, physical activity, and multiple pregnancies may be important factors that contribute to the increased prevalence of obesity engulfing the Arabic-speaking countries.

    This is the first genetic anthropology study on Arabs in MENA (Middle East and North Africa) region. The present meta-analysis included 100 populations from 36 Arab and non-Arab communities, comprising 16,006 individuals, and evaluates the genetic profile of Arabs using HLA class I (A, B) and class II (DRB1, DQB1) genes. A total of 56 Arab populations comprising 10,283 individuals were selected from several databases, and were compared with 44 Mediterranean, Asian, and sub-Saharan populations. The most frequent alleles in Arabs are A*01, A*02, B*35, B*51, DRB1*03:01, DRB1*07:01, DQB1*02:01, and DQB1*03:01, while DRB1*03:01-DQB1*02:01 and DRB1*07:01-DQB1*02:02 are the most frequent class II haplotypes. Dendrograms, correspondence analyses, genetic distances, and haplotype analysis indicate that Arabs could be stratified into four groups. The first consists of North Africans (Algerians, Tunisians, Moroccans, and Libyans), and the first Arabian Peninsula cluster (Saudis, Kuwaitis, and Yemenis), who appear to be related to Western Mediterraneans, including Iberians; this might be explained for a massive migration into these areas when Sahara underwent a relatively rapid desiccation, starting about 10,000 years BC. The second includes Levantine Arabs (Palestinians, Jordanians, Lebanese, and Syrians), along with Iraqi and Egyptians, who are related to Eastern Mediterraneans. The third comprises Sudanese and Comorians, who tend to cluster with Sub-Saharans. The fourth comprises the second Arabian Peninsula cluster, made up of Omanis, Emiratis, and Bahrainis. It is noteworthy that the two large minorities (Berbers and Kurds) are indigenous (autochthonous), and are not genetically different from “host” and neighboring populations. In conclusion, this study confirmed high genetic heterogeneity among present-day Arabs, and especially those of the Arabian Peninsula. PMID:29522542

    Male circumcision is almost universal in North and West Africa, and practiced for various reasons. Yet there is little documentation on service delivery, clinical procedures, policies, and programmatic strategies. The United Nations Children's Fund (UNICEF) commissioned country program reviews in 2014 to shed light on the delivery of male circumcision services for infants in Cameroon and Senegal. We conducted a policy desk review, key informant interviews, and focus group discussions at health centers and in communities. Between December 2014 and January 2015, we conducted 21 key informant interviews (13 with regional and district officers, 5 with national officers, and 3 with UNICEF officials) and 36 focus group discussions (6 with men, 6 with women, 12 with adolescent boys, and 12 with service providers). Some of the men and women were parents of the adolescents who participated in the focus group discussions. In the French-speaking areas, the focus group discussions were conducted in French through an accredited translator, audio recorded, and transcribed into English. All of the facilities we visited in Cameroon and Senegal offer medical male circumcision, with 10 out of 12 performing early infant male circumcision (EIMC) routinely. Neither country has policies, guidelines, or strategies for EIMC. The procedure is done mainly by untrained service providers, with some providers using modern circumcision devices. There are no key messages on EIMC for families; the increasing demand for EIMC is led by the community. Despite the absence of national policies and strategies, EIMC is routinely offered at all levels of the health care system in Cameroon and Senegal, mainly by untrained service providers. Improving circumcision services will require guidelines for EIMC and improvements in training, equipment, supply chains, recordkeeping, and demand creation. © Kenu et al.

    To develop Arabic versions of English language questionnaires to estimate morningness/eveningness and sleep variables. We translated the Composite scale of morningness (CSM) and the sleep timing questionnaire (STQ) [with added siesta questions] into Arabic; the Arabic versions were then back translated. The revised Arabic and the original English versions were next administered to bi-lingual Egyptians using a crossover design (n=25). The Arabic versions of both scales were subsequently administered to an independent Egyptian sample (n=79) and the siesta variables examined in relation to the CSM. Satisfactory correlations were present between the English and Arabic versions for total CSM scores (Spearman's ρ=0.90, p<0.001). All but one of the STQ variables were significantly correlated (Spearman's ρ=0.45-0.88, p≤0.05). In the Arabic version, the frequency of siesta naps per week was significantly correlated with the total CSM score, with evening types taking more naps (Spearman's ρ=-0.23, p≤0.05). Arabic versions of the STQ and CSM have been developed in Egypt, and are freely available. They can be used for behavioral research related to sleep and circadian function and can be adapted for use in other Arab speaking populations. Copyright © 2014 Elsevier B.V. All rights reserved.

    The incidence of ischemic heart disease is rising rapidly in many of the affluent Arab countries and it is known that hypercholesterolemia is a well established risk factor for coronary artery disease. This community-based study was undertaken to determine if elevated cholesterol is a problem in the United Arab Emirates in order to be able to evaluate the contribution of cholesterol as a risk factor for atherosclerosis in this environment. Volunteers were recruited at busy urban public sites. Data on age, sex, nationality, weight, blood pressure and smoking history were collected, and blood samples were taken for estimation of total cholesterol, hemoglobin and individual blood group. A raw data set was developed, with calculation of body mass index and subsequent statistical analysis carried out on a PC using the SPSS programme. In the 834 patients, there were 19 nationalities represented which were pooled into 7 groups (5 Arab and 2 non Arab) according to their ethnic origins. The prevalence of hypercholesterolemia varied from 47.2-53% in the Arab Nationals and from 22.7 to 44.5% in the non Arabs. The mean cholesterol levels of the Arab subgroups were similar and showed no difference, statistically. However, they were significantly higher than non Arabs, i.e. Indians (p < 0.001) and Iranians (p < 0.001). Similarly, within the Arab subgroups, the median cholesterol levels were no different but were higher than the non Arabs, i.e. Indians (p < 0.05) and Iranians (p < 0.001). No statistical difference was found in the distribution of cholesterol (high, borderline high or desirable levels) among the seven ethnic groups. Hypercholesterolemia appears to be a problem in most nationalities living within the UAE. Overall, it afflicts nearly 50% of the adult population. Although the ethnic Arab groupings have a wide range of socioeconomic attributes, the similarity of the distribution of cholesterol may point to an underlying innate genetic etiology or an environmental

    Cultural variations among ethnic groups may differentially influence health and health behavior. We explored and compared health-promoting lifestyle behaviors and psychological status, including depression, anxiety, and stress, among Korean migrants (n = 117) and Arab nationals (n = 103) in the United Arab Emirates (UAE). Pender's Health Promotion Model guided this research. The Health-Promoting Lifestyle Profile was used to measure health-promoting lifestyle behaviors and Lovibond and Lovibond's Depression, Anxiety, and Stress Scale to measure psychological status. The data were analyzed using bivariate procedures and multiple linear regression. No group differences were found in total scores for health-promoting lifestyle behaviors or psychological status. Both groups scored high on self-actualization and interpersonal support; Arabs scored low on exercise, and Koreans scored low on health responsibility. Across groups, psychological status (β = -.390, p < .001), education (β = .239, p < .001), and gender (β = .238, p < .001) were significant determinants of health-promoting lifestyle behaviors in multivariate analysis. Ethnicity and religious attendance were not significant determinants. Education level had a moderating effect; for those with a lower educational level, psychological distress had a stronger negative effect on health behavior. Findings suggest considering cultural aspects, such as different values placed on physical fitness and social/interpersonal relationships, in developing and implementing health education and/or promotion programs. Assessment of psychological status (i.e., depression, anxiety, and stress) should also be included in health promotion programs and related health policies for Korean migrants and Arab nationals in the UAE. © 2015 Wiley Periodicals, Inc.

    This study addresses diversity of aging experiences by examining the associations among immigrant status, religious affiliation, and resources in the form of both human and social capital with the well-being of Arab-American elders. Data were drawn from a face-to-face survey of 101 Arab-American men and women aged 56 and over living in the metropolitan Detroit area. Correlations demonstrate that religious affiliation is not associated with well-being. Multiple regression analyses reveal that U.S. born Arab Americans reported less frequent feelings of depression and greater life satisfaction than did immigrants, but this variation appears to be accounted for by human capital indicators including education level and language. Social capital including perceptions of the ability to confide in child and relationship quality with spouse is significantly associated with well-being, yet does not constitute a pathway to well-being for Arab-American elders. Human and social capital represent valuable resources and their distribution within this immigrant/ethnic group is associated with noteworthy variations in well-being.

    Objectives To assess antibiotic susceptibility of community-acquired respiratory tract isolates from Ivory Coast, Kenya, Democratic Republic of Congo (DRC) and Senegal in 2011–14. Methods Bacterial isolates were collected and MICs determined using Etest® for all antibiotics except erythromycin, for which testing was by disc diffusion. Susceptibility was assessed using CLSI, EUCAST and pharmacokinetic/pharmacodynamic (PK/PD) breakpoints. For macrolide interpretation, CLSI breakpoints were adjusted for incubation in CO2. Results Susceptibility to penicillin (using CLSI oral or EUCAST breakpoints) was low among isolates of Streptococcus pneumoniae from the DRC and Kenya (17.4% and 19%, respectively) but higher among isolates from the Ivory Coast (70%) and Senegal (85.7%). Penicillin susceptibility using CLSI iv breakpoints was higher in all countries, but still only 69.6% in the DRC. Macrolide susceptibility (based on CLSI erythromycin disc diffusion breakpoints) was also low in Kenya (∼65%) but 87%–100% elsewhere. Haemophilus influenzae were only collected in the DRC and Senegal, with β-lactamase prevalence of 39% and 4%, respectively. Furthermore, β-lactamase-negative ampicillin-resistant (BLNAR) isolates were found in DRC (four isolates, 17%), but only two isolates were found in Senegal (by EUCAST definition). Amoxicillin/clavulanic acid in vitro susceptibility was 73.9% in the DRC and 100% in Senegal based on CLSI breakpoints, but this reduced to 65.2% in the DRC when BLNAR rates were considered. Clarithromycin susceptibility was >95% in both countries. Conclusions There was considerable variability in antibiotic susceptibility among the African countries participating in the surveillance programme. Thus, continued surveillance is necessary to track future changes in antibiotic resistance. Use of EUCAST versus CLSI breakpoints showed profound differences for cefaclor and ofloxacin against S. pneumoniae, with EUCAST showing lower susceptibility. PMID

    This study on the ideal family size in Arab countries, is based on the findings of the World Fertility Survey led in 8 Arab countries (Egypt, 1980; Jordan, 1976; Morocco, 1980; Mauritania, 1981; Sudan, 1979; Syria, 1978; Tunisia, 1978; and Arab Republic of Yemen, 1979). During these surveys, a questionnaire was presented to a specimen of 2,500 to 8,500 women, 1st to married and fertile women, then to childless or pregnant women. The study of the responses shows that a great majority of Arab women desire a large family. Less than 20% of them do not want to have another child in the future in Mauritania, Sudan, and Yemen; between 37% and 53% in the 5 other countries. The total number of children wanted is 4.9 in Morocco, 5.4 in Yemen, 6.1 in Sudan, 6.3 in Jordan and Syria, and 8.7 in Mauritania. Women prefer to have boys rather than girls. In Egypt and Tunisia, respectively, 83% and 66% do not want to have another child when there are as many boys as girls in the family. As expected, the more children a woman has, the less she wants to have another one. The more women use contraception and modern contraceptives, the less they want another child. Of the women who do not want another child, 67% are using contraception in Tunisia, 65% in Egypt, 50% in Syria, Morocco, and Jordan, but 25% in Sudan, 17% in Yemen, and 15% in Mauritania. The transition from natural fertility to planned fertility is very slow in Mauritania, Yemen, and Sudan, while Syria and Jordan present the beginning of an evolution. The decline of fertility is faster in Egypt, Tunisia, and Morocco. In Arab countries, the weight of the traditional patriarchal family, and the lack of education and social opportunities for women is slowing down demographic transition.

    Attachment orientations reflect internal representations of self, others, and relationships. Studies revealed meaningful cultural differences in attachment orientations, but few included Arab samples. to fill this gap, we compared attachment orientations of Jews and Arabs in Israel using valid measures. Israeli participants (292 Arabs and 206 Jews) described their attachment figures and completed the Experiences in Close Relationships questionnaire which measures anxious and avoidant attachment orientations in Arabic and Hebrew, respectively. Israeli Arabs reported higher attachment anxiety than Israeli Jews, but no difference was found in avoidance. Both groups reported that attachment figures were similar in gender and relationship type, and included romantic partners, relatives and friends. Findings should be considered cautiously due to sampling limitations. the results complement previous cross-cultural findings and Arabs-Jews differences in relationship-related norms/values. Higher attachment-anxiety scores observed among Israeli Arabs may be considered culturally normative with implications for the development of culturally competent interventions.

    We calculated cancer incidence for Arab Americans in California; Detroit, Michigan; and New Jersey, and compared rates with non-Hispanic, non-Arab Whites (NHNAWs); Blacks; and Hispanics. We conducted a study using population-based data. We linked new cancers diagnosed in 2000 from the Surveillance, Epidemiology, and End Results Program (SEER) to an Arab surname database. We used standard SEER definitions and methodology for calculating rates. Population estimates were extracted from the 2000 US Census. We calculated incidence and rate ratios. Arab American men and women had similar incidence rates across the 3 geographic regions, and the rates were comparable to NHNAWs. However, the thyroid cancer rate was elevated among Arab American women compared with NHNAWs, Hispanics, and Blacks. For all sites combined, for prostate and lung cancer, Arab American men had a lower incidence than Blacks and higher incidence than Hispanics in all 3 geographic regions. Arab American male bladder cancer incidence was higher than that in Hispanics and Blacks in these regions. Our results suggested that further research would benefit from the federal recognition of Arab Americans as a specified ethnicity to estimate and address the cancer burden in this growing segment of the population.

    To compare barriers to infertility care among African Americans and Arab Americans. Qualitative study using semi-structured reproductive histories and open-ended ethnographic interviews. Infertile volunteers in a private IVF clinic in Dearborn, Michigan, an Arab American ethnic enclave community in metropolitan Detroit. Arab American men presenting for infertility diagnosis and treatment, including assisted reproductive technologies. None. Perceived barriers to effective infertility care. Arab Americans and African Americans living in metropolitan Detroit are at increased risk of infertility and share similar histories of poverty, racism, and cultural barriers to medical treatment. This study, which focused on infertile Arab American men living in or near Dearborn (an ethnic enclave community composed mainly of recent immigrants and war refugees), revealed significant barriers to effective infertility care, including economic constraints, linguistic and cultural barriers, and social marginalization in mainstream U.S. society, particularly after September 11, 2001. Arab Americans experience disparities in access to infertility care, largely because of poverty and social marginalization in post-September 11th America.

    Awang, K.; Taylor, D.

    With deforestation in the Asia-Pacific region progressing at the rate of 4.4 million ha per year, many countries have adopted plantation forestry using fast-growing species as a way to sustain the commercial supply of tree products and reduce pressure on natural forests. Acacia mangium (A. mangium) is playing a large role in this development, especially in Indonesia and Malaysia, due to its versatility and its ability to recapture grasslands dominated by the noxious weed, Imperata cylindrica. This monograph consolidates information on A. mangium from published literature, unpublished reports and studies, and observations from those familiar with the species.

    The problem of optical character recognition (OCR) of handwritten Arabic has not received a satisfactory solution yet. In this paper, an Arabic OCR algorithm is developed based on Hidden Markov Models (HMMs) combined with the Viterbi algorithm, which results in an improved and more robust recognition of characters at the sub-word level. Integrating the HMMs represents another step of the overall OCR trends being currently researched in the literature. The proposed approach exploits the structure of characters in the Arabic language in addition to their extracted features to achieve improved recognition rates. Useful statistical information of the Arabic language is initially extracted and then used to estimate the probabilistic parameters of the mathematical HMM. A new custom implementation of the HMM is developed in this study, where the transition matrix is built based on the collected large corpus, and the emission matrix is built based on the results obtained via the extracted character features. The recognition process is triggered using the Viterbi algorithm which employs the most probable sequence of sub-words. The model was implemented to recognize the sub-word unit of Arabic text raising the recognition rate from being linked to the worst recognition rate for any character to the overall structure of the Arabic language. Numerical results show that there is a potentially large recognition improvement by using the proposed algorithms.

    Research that explains health of Arab and Chaldean Americans relative to the health of non-Arab White Americans is limited but steadily increasing. This study considers whether socioeconomic status moderates the relationship between race/ethnicity and physical and mental health. Data come from a state representative sample of Arab and Chaldean Americans-the 2013 Michigan Behavioral Risk Factor Survey and the 2013 Michigan Arab/Chaldean Behavioral Risk Factor Survey (N = 12,837 adults with 536 Arab/Chaldean Americans). Structural equation models examine whether socioeconomic status, operationalized as educational attainment, moderates the relationship between Arab/Chaldean identity and health, and whether physical activity, access to healthcare, and depression mediate the relationship between educational attainment and health. Results indicate that while Arab/Chaldean Americans have poor health relative to non-Arab White Americans, these differences are largely explained by educational differences. Depression, access to healthcare, and physical activity mediate the relationship between socioeconomic status and health of Arab/Chaldean Americans.

  4. Host-driven diversification of gall-inducing Acacia thrips and the aridification of Australia

    2007-01-01

    Background Insects that feed on plants contribute greatly to the generation of biodiversity. Hypotheses explaining rate increases in phytophagous insect diversification and mechanisms driving speciation in such specialists remain vexing despite considerable attention. The proliferation of plant-feeding insects and their hosts are expected to broadly parallel one another where climate change over geological timescales imposes consequences for the diversification of flora and fauna via habitat modification. This work uses a phylogenetic approach to investigate the premise that the aridification of Australia, and subsequent expansion and modification of arid-adapted host flora, has implications for the diversification of insects that specialise on them. Results Likelihood ratio tests indicated the possibility of hard molecular polytomies within two co-radiating gall-inducing species complexes specialising on the same set of host species. Significant tree asymmetry is indicated at a branch adjacent to an inferred transition to a Plurinerves ancestral host species. Lineage by time diversification plots indicate gall-thrips that specialise on Plurinerves hosts differentially experienced an explosive period of speciation contemporaneous with climatic cycling during the Quaternary period. Chronological analyses indicated that the approximate age of origin of gall-inducing thrips on Acacia might be as recent as 10 million years ago during the Miocene, as truly arid landscapes first developed in Australia. Conclusion Host-plant diversification and spatial heterogeneity of hosts have increased the potential for specialisation, resource partitioning, and unoccupied ecological niche availability for gall-thrips on Australian Acacia.

    Unlocking the agricultural potential of Africa offers a genuine opportunity to address malnutrition and drive development of the continent. Using Senegal as a case study, to identify gaps and opportunities to strengthen agricultural policies with nutrition-sensitive approaches. We carried out a systematic analysis of 13 policy documents that related to food production, agriculture, food security, or nutrition. Next, we collected data during a participatory analysis with 32 national stakeholders and in-depth interviews with 15 national experts of technical directorates of the different ministries that deal with agriculture and food production. The current agricultural context has various elements that are considered to enhance its nutrition sensitivity. On average, 8.3 of the 17 Food and Agriculture Organization guiding principles for agriculture programming for nutrition were included in the policies reviewed. Ensuring food security and increasing dietary diversity were considered to be the principal objectives of agricultural policies. Although there was considerable agreement that agriculture can contribute to nutrition, current agricultural programs generally do not target communities on the basis of their nutritional vulnerability. Agricultural programs were reported to have specific components to target female beneficiaries but were generally not used as delivery platforms for nutritional interventions. The findings of this study indicate the need for a coherent policy environment across the food system that aligns recommendations at the national level with local action on the ground. In addition, specific activities are needed to develop a shared understanding of nutrition and public health nutrition within the agricultural community in Senegal. © The Author(s) 2015.

  6. Speech disorders in Israeli Arab children.

    1997-10-01

    The aim of this work was to study the frequency of speech disorders in Israeli Arab children and its association with parental consanguinity. A questionnaire was sent to the parents of 1,495 Arab children attending kindergarten and the first two grades of the seven primary schools in the town of Taibe. Eight-six percent (1,282 parents) responded. The answers to the questionnaire revealed that 25% of the children reportedly had a speech and language disorder. Of the children identified by their parents as having a speech disorder, 44 were selected randomly for examination by a speech specialist. The disorders noted in this subgroup included errors in articulation (48.0%), poor language (18%), poor voice quality (15.9%); stuttering (13.6%), and other problems (4.5%). Rates of affected children of consanguineous and non-consanguineous marriages were 31% and 22.4%, respectively (p < 0.01). We conclude that speech disorders are an important problem among Israeli Arab schoolchildren. More comprehensive programs are needed to facilitate diagnosis and treatment.

  7. Veno-occlusive disease and primary hepatic vein thrombosis in Israeli Arabs.

    1981-05-01

    In a survey of nine major Israeli hospitals, 29 patients diagnosed between 1955 and 1975 as suffering from hepatic vein thrombosis were identified. Fifteen of the patients were Jews and 14 were Arabs. In contrast to the Jewish patients, all of whom were adults, the majority of the Arab patients were children below 10 years of age. Primary hepatic vein occlusion was 2.4 times more common among Arab than among Jewish patients. Of the 11 Arab patients with primary hepatic vein occlusion, three had histological changes typical of veno-occlusive disease; whereas in five others, thrombotic occlusion of large hepatic veins or of the vena cava was documented. Although no plant alkaloids could be directly implicated in any of the Arab patients, circumstantial evidence strongly supports such an etiology. All of our Arab patients originated from small agricultural communities where ancient methods of winnowing, which expose the home-ground wheat to a high risk of contamination by grains containing pyrrolizidine alkaloids, are still in use. This report confirms the world-wide distribution of veno-occlusive disease, and under-lines the need for a systematic search for possible sources of poisoning by pyrrolizidine alkaloids.

    Birth defects and genetic disorders are leading causes of infant morbidity and mortality in many countries. Population-based data on birth defects among Arab-American children have not been documented previously. Michigan has the second largest Arab-American community in the United States after California. Using data from the Michigan Birth Defects Registry (MBDR), which includes information on parents' country of birth and ancestry, birth prevalences were estimated in offspring of Michigan women of Arab ancestry for 21 major categories of birth defects and 12 congenital endocrine, metabolic, and hereditary disorders. Compared with other non-Hispanic white children in Michigan, Arab-American children had similar or lower birth prevalences of the selected types of structural birth defects, with higher rates of certain hereditary blood disorders and three categories of metabolic disorders. These estimates are important for planning preconception and antenatal health care, genetic counseling, and clinical care for Arab Americans.

    This study aims to characterize the ectomycorrhizal (ECM) communities associated with Acacia spirorbis, a legume tree widely spread in New Caledonia that spontaneously grows on contrasted edaphic constraints, i.e. calcareous, ferralitic and volcano-sedimentary soils. Soil geochemical parameters and diversity of ECM communities were assessed in 12 sites representative of the three mains categories of soils. The ectomycorrhizal status of Acacia spirorbis was confirmed in all studied soils, with a fungal community dominated at 92% by Basidiomycota, mostly represented by/tomentella-thelephora (27.6%), /boletus (15.8%), /sebacina (10.5%), /russula-lactarius (10.5%) and /pisolithus-scleroderma (7.9%) lineages. The diversity and the proportion of the ECM lineages were similar for the ferralitic and volcano-sedimentary soils but significantly different for the calcareous soils. These differences in the distribution of the ECM communities were statistically correlated with pH, Ca, P and Al in the calcareous soils and with Co in the ferralitic soils. Altogether, these data suggest a high capacity of A. spirorbis to form ECM symbioses with a large spectrum of fungi regardless the soil categories with contrasted edaphic parameters.

    2016-08-01

    The Cardiac Depression Scale (CDS) has been designed to measure depressive symptoms in patients with heart disease. There is no Arabic version of the CDS. We translated and validated the CDS in an Arabic sample of patients with heart disease. Forward and back translation of the CDS was followed by assessment of cultural relevance and content validity. The Arabic version of the CDS (A-CDS) and the Arabic version of the Hospital Anxiety and Depression Scale (A-HADS) were then administered to 260 Arab in-patients with heart disease from 18 Arabic countries. Construct validity was assessed using exploratory factor analysis with polychoric correlations. Internal consistency was assessed using ordinal reliability alpha and item-to-factor polychoric correlations. Concurrent validity was assessed using Pearson's correlation coefficient between the A-CDS and the depression subscale of the A-HADS (A-HADS-D). Cultural relevance and content validity of the A-CDS were satisfactory. Exploratory factor analysis revealed three robust factors, without cross-loadings, that formed a single dimension. Internal consistency was high (ordinal reliability alpha for the total scale and the three factors were .94, .91, .86, and .87, respectively; item-to-factor correlations ranged from .77 to .91). Concurrent validity was high (r=.72). The A-CDS demonstrated a closer to normal distribution of scores than the A-HADS-D. Sensitivity and specificity of the A-CDS were not objectively assessed. The A-CDS appears to be a valid and reliable instrument to measure depressive symptoms in a representative sample of Arab in-patients with heart disease. Copyright © 2016 Elsevier B.V.

  11. [Manpower migrations and Arab unity: the challenges of the Iraqi model].

    PubMed

    Roussillon, A

    1985-01-01

    Iraq occupies a unique position in the system of manpower exchanges between Middle Eastern states brought about by the rise in petroleum incomes of the 1970s. Iraq was among the most important oil exporters until the war with Iran, but its economy is predominantly agricultural, it is a rich country in terms of available financial resources, and it is both an importer and exporter of labor, traits which place it squarely between the nonoil-producing states which are poor and overpopulated and the oil exporters which are rich and underpopulated. Its migration policy, which radically distinguishes between Arab and non-Arab manpower, is also unique. Data on migration to Iraq are very sparse despite the fact that the nation has a good data-gathering capacity. Estimates of migration to Iraq and employment patterns of migrants have varied widely and have contradicted each other in crucial respects. The most unusual aspect of Iraqi immigration policy, the free access offered to Egyptians and other Arabs, has hampered attempts to estimate the volume of migration, as workers come and go for relatively short periods, seeking their own employment in Iraq and working in jobs for which they may be overqualified. Official formulations of Iraqi migration policy insist that migration should not only be beneficial to individual importing and exporting countries in terms of development and social cohesion, but should also reinforce the solidarity and regional complementarity of the Arab world as a whole. Iraqi migration policy is presented as expressing the most fundamental choices of the "Arab revolution" in the socialist dimension of Arab unitary ideology rather than in terms of immediate national economic interest. Iraqi legislation grants non-Iraqi Arabs the same labor, residence, investment, and ultimately naturalization rights as those enjoyed by nationals, but severely restricts access to employment and other rights of non-Arab foreigners.

    While it is generally agreed that traditional societies are more favorable toward their elders, research findings have been inconsistent. Accordingly, this study presents a cultural comparison between Jews and Arabs in Israel in attitudes toward older adults and personal views regarding one's own aging. It was assumed that Arabs would rate their culture as more tolerant toward older adults, would report spending more time with them, and express lower ageism and aging anxieties. We examined 154 native Israeli citizens, 86 Jewish and 68 Muslim Arabs, who completed measures of ageism, aging anxieties, and cultural views of older adults. Arabs rated their culture as more tolerant toward their elders, perceived older adults as significantly more contributing to society, and reported engaging in less avoiding behaviors toward them. Arabs also exhibited less general fears of growing old and concerns over one's physical appearance in old age. But it was interesting to note that Arab women reported higher scores of aging anxieties and ageist attitudes in comparison to Arab men, whereas no such differences were found among Jews. Our findings point that the cultural importance of elders for the Arab cohort transcends beyond Westernization processes which affect the Arab society in Israel, and reflect the demanding role of Arab women as primary caregivers for the elders in the family. Limitations and implications of the study are discussed.

  14. The acacia ants revisited: convergent evolution and biogeographic context in an iconic ant/plant mutualism

    PubMed Central

    2017-01-01

    Phylogenetic and biogeographic analyses can enhance our understanding of multispecies interactions by placing the origin and evolution of such interactions in a temporal and geographical context. We use a phylogenomic approach—ultraconserved element sequence capture—to investigate the evolutionary history of an iconic multispecies mutualism: Neotropical acacia ants (Pseudomyrmex ferrugineus group) and their associated Vachellia hostplants. In this system, the ants receive shelter and food from the host plant, and they aggressively defend the plant against herbivores and competing plants. We confirm the existence of two separate lineages of obligate acacia ants that convergently occupied Vachellia and evolved plant-protecting behaviour, from timid ancestors inhabiting dead twigs in rainforest. The more diverse of the two clades is inferred to have arisen in the Late Miocene in northern Mesoamerica, and subsequently expanded its range throughout much of Central America. The other lineage is estimated to have originated in southern Mesoamerica about 3 Myr later, apparently piggy-backing on the pre-existing mutualism. Initiation of the Pseudomyrmex/Vachellia interaction involved a shift in the ants from closed to open habitats, into an environment with more intense plant herbivory. Comparative studies of the two lineages of mutualists should provide insight into the essential features binding this mutualism. PMID:28298350

    Japanese policy toward the Arab states for the five years before the embargo are compared with the five years that followed. Significant events from October 1973 through the February 1974 Washington Conference are described on a virtually daily basis. The study concludes that the late 1973 oil-supply reduction did not result in significantly greater Japanese political support or economic assistance in the 1974-1978 period. Japan did not even carry the only specific commitment in the November 22 statement - that it would reconsider relations with Israel if that country didn't withdraw from the occupied Arab territories. Many factors contributed tomore » this failure - American counter-pressure, Arab disunity, and a worldwide drop in oil demand. In terms of political demands, neither OAPEC nor any individual Arab state ever articulated any specific actions Japan was to take. Finally, the supply of oil was rapidly depoliticized after 1974.« less

  17. The stigma of mental illness in Arab families: a concept analysis.

    2015-11-01

    The stigma of mental illness varies significantly from culture to culture and from person to person. To date, little is known about how mental illness stigma manifests within the Arab community. This study aimed at bringing clarity to the concept of 'mental illness stigma' as it applies to Arab families. Nursing's holistic and patient-centered approach is integral to helping Arab patients and their families appropriately incorporate individual values, beliefs, and cultural perspectives into treatment plans. This study establishes a scientific alert for professionals at all levels to avoid making false generalizations about a specific culture that are not based on specific research findings from that culture. Accessing mental health services is a critical step towards reducing the burden of mental illness. The stigma of mental illness is one of the most common reasons for not seeking mental health care leading to negative health consequences and undue suffering for many individuals and their families. Stigma is embedded in its social context. What may be considered acceptable in one society may be considered unacceptable and open to stigmatization in other societies. Arabs have a shared set of values, beliefs, and traditions that are substantially different from those of Westerners. Further, in most Arab countries, formal mental health resources are scarce and people with mental illness experience the compounded disadvantages of poverty and illness stigma. To date, little is known about how mental illness stigma manifests within the Arab community making it difficult to design and test interventions that support Arab individuals with mental illness and their families in treatment seeking and adherence. Using Rodger's concept analysis method, we examined how 'mental illness stigma' operates within an Arab context as a first step towards elucidating culturally competent approaches to treatment. This analysis provides a foundation for future work in the areas of mental

This fact would suggest that A. caven populations occurring in the south are in better conditions for reproduction than northern populations, since pod-length is related to the amount of seeds inside the pods. The possible bearing of this southward tendency of increasing seed production upon the expansion of A. caven toward the more humid zones in southern Chile is discussed.
