    2017-06-01

    NOOR III 150 MWe project is the evolution of Gemasolar (19.9 MWe) to large scale Molten Salt Tower plants. With more than 5 years of operational experience, Gemasolar lessons learned have been the starting point for the optimization of this technology, considered the leader of potential cost reduction in CSP. In addition, prototypes of plant key components (heliostat and receiver) were manufactured and thoroughly tested before project launch in order to prove the new engineering solutions adopted. The SENER proprietary technology of NOOR III will be applied in the next Molten Salt Tower plants that will follow in other countries, such as South Africa, Chile and Australia.

    Blackmon, James B

    2008-03-31

    This report documents the efforts conducted primarily under the Noor al Salaam (“Light of Peace”) program under DOE GRANT NUMBER DE-FC36-02GO12030, together with relevant technical results from a closely related technology development effort, the U.S./Israel Science and Technology Foundation (USISTF) High Concentration Solar Central Receiver program. These efforts involved preliminary design, development, and test of selected prototype power production subsystems and documentation of an initial version of the system definition for a high concentration solar hybrid/gas electrical power plant to be built in Zaafarana, Egypt as a first step in planned commercialization. A major part of the planned work was halted in 2007 with an amendment in October 2007 requiring that we complete the technical effort by December 31, 2007 and provide a final report to DOE within the following 90 days. This document summarizes the work conducted. The USISTF program was a 50/50 cost-shared program supported by the Department of Commerce through the U.S./Israel Science and Technology Commission (USISTC). The USISTC was cooperatively developed by President Clinton and the late Prime Minister Rabin of Israel "to encourage technological collaboration" and "support peace in the Middle East through economic development". The program was conducted as a follow-on effort to Israel's Magnet/CONSOLAR Program, which was an advanced development effort to design, fabricate, and test a solar central receiver and secondary optics for a "beam down" central receiver concept. The status of these hardware development programs is reviewed, since they form the basis for the Noor al Salaam program. Descriptions are provided of the integrated system and the major subsystems, including the heliostat, the high temperature air receiver, the power conversion unit, tower and tower reflector, compound parabolic concentrator, and the master control system. One objective of the USISTF program was to conduct

  4. Assessment of rockfall hazard at Al-Noor Mountain, Makkah city (Saudi Arabia) using spatio-temporal remote sensing data and field investigation

    Rockfall is one of the major concerns along different urban areas and highways all over the world. Al-Noor Mountain is one of the areas that threaten rockfalls to the Al-Noor escarpment track road and the surrounding urban areas. Thousands of visitors and tourisms use the escarpment track road to visit Hira cave which is located at the top of Al-Noor Mountain. In addition, the surrounding urban areas of Al-Noor Mountain are continuously spreading over the recent years. The escarpment track road and the surrounding urban areas are highly vulnerable and suffers from recurrent rockfall mostly in the rainy season. The steep and highly jointed slope along the different faces of the mountain makes these zones prone to failure due to different actions such as weathering, erosion and anthropogenic effect. Therefore, an attempt has been made in this study to determine the Al-Noor cliff stability, by identifying the unstable areas, and to apply the rockfall simulations. A combination of remote sensing, field study and 2D computer simulation rockfall program were performed to assess surface characteristics of the cliff faces. Bounce height, total and translational kinetic energy, translational velocity, and number of blocks have been estimated. Different unstable zones along the Al-Noor Mountain and escarpment track road were determined using filed investigation and remote sensing based image analysis. In addition the rockfall simulation analysis indicated that rockfall in zone 1 and zone 2 of the Al-Noor Mountain may reach the urban areas, whereas rockfall in zone 3 will not reach the urban areas, and rockfalls along the Al-Noor escarpment track road will have highly impact on the tourists. Proper preventive measures are also suggested to arrest the movement of falling rocks before reaching the urban areas and the Al-Noor escarpment track road. If proper care is taken, then further uncertain rockfall hazards can be prevented.

    Objective: Hajj usually presents a unique medical crisis especially for the Emergency Department. This study will identify the surgical and medical cases that presented at the Emergency Department during Hajj and percentage admitted. Design: A prospective study of the pattern of surgical and medical cases that presented at the Emergency Department of the largest tertiary care hospital in Makkah city and holy lands during Hajj. Methods: The study was conducted prospectively during the 1413 (1993) Hajj pilgrimage from 20.11.1413 to 20.12.1413. All Saudi and non-Saudi pilgrims presenting at the Emergency Department of Al-Noor Specialist Hospital were included. Results: From the 7,676 patients who came to the Emergency Department, 1426 were admitted. The commonest cause for surgical admission was trauma, while the commonest cause for medical admission was pneumonia. Conclusion: More than 50% of cases could have been dealt with in the Outpatient Department or Primary Health Care Centers. PMID:23008609

    This is the first study to investigate the completely anti-atherogenic effect of Deglet Noor Date seeds methanol extract administration on diet-induced hypercholesterolemic rats. About 24 male Wistar rats were divided into 6 groups. The normal control (NC) group, Hypercholesterolemic Control (HC) group was given high cholesterol diet, and Simvastatin Control (SC) group was given 0.18 mg/200g simvastatin after high cholesterol diet induction. The treatment groups of T0.25, T0.5 and T1 were given supplementation of 0.25, 0.5 and 1 g/kg of dates seed extract after high cholesterol diet induction, respectively for 21 days. Blood was collected from orbitals plexus vein for plasma lipid profile analysis. The levels of Total Cholesterol (TC), Low-Density Lipoprotein (LDL) and Atherogenic Index (AI) values were significantly decreased (p<0.05) on diet-induced hypercholesterolemic rats after supplemented with date seeds extract (T0.25, T0.5 and T1) but not in Triglycerides (TG). Along with that, High Density Lipoprotein (HDL) level was significantly increased (p<0.05). However, the T1 group was the best anti-atherogenic activity in compared to other groups. Results showed that plasma lipid profile was significant to get better after supplemented with date seeds extract.

  18. Comparative Demography of the Spider Mite, Oligonychus afrasiaticus, on four Date Palm Varieties in Southwestern Tunisia

    PubMed Central

    Chaaban, Sameh Ben; Chermiti, Brahim; Kreiter, Serge

    2011-01-01

    The date palm mite, Oligonychus afrasiaticus (McGregor) (Acari: Tetranychidae), is a serious pest of palm date fruits. Life cycle, fecundity, and longevity of this mite were studied on fruits of four date palms, Phoenix dactylifera L. (Arecales: Arecaceae)(varieties: Deglet Noor, Alig, Kentichi, and Besser), under laboratory conditions at 27 = 1 °C, 60 ± 10% RH. Total development time of immature female was shorter on Deglet Noor fruits than on the other cultivars. O. afrasiaticus on Deglet Noor had the highest total fecundity per female, while low fecundity values occurred on Besser. The comparison of intrinsic rates of natural increase (rm), net reproductive rates (Ro), and the survival rates of immature stage of O. afrasiaticus on the host plants suggests that O. afrasiaticus performs better on Deglet Noor fruits. The mite feeding on Alig showed the lowest intrinsic rate of natural population increase (rm = 0.103 day 1). The estimation of difference in susceptibility of cultivars to O. afrasiaticus is crucial for developing efficient pest control programs. Indeed, less susceptible cultivars can either be left unsprayed or sprayed at low threshold. PMID:22233420

    We describe a new version of the Parameterized Regional Ionospheric Model (PARIM) which has been modified to include the longitudinal dependences. This model has been reconstructed using multidimensional Fourier series. To validate PARIM results, the South America maps of critical frequencies for the E (foE) and F (foF2) regions were compared with the values calculated by Sheffield Plasmasphere-Ionosphere Model (SUPIM) and IRI representations. PARIM presents very good results, the general characteristics of both regions, mainly the presence of the equatorial ionization anomaly, were well reproduced for equinoctial conditions of solar minimum and maximum. The values of foF2 and hmF2 recorded over Jicamarca (12°S; 77°W; dip lat. 1°N; mag. declination 0.3°) and sites of the conjugate point equatorial experiment (COPEX) campaign Boa Vista (2.8°N; 60.7°W; dip lat. 11.4°; mag. declination -13.1°), Cachimbo (9.5°S; 54.8°W; dip lat. -1.8°; mag. declination -15.5°), and Campo Grande (20.4°S; 54.6°W; dip lat. -11.1°; mag. declination -14.0°) have been used in this work. foF2 calculated by PARIM show good agreement with the observations, except during morning over Boa Vista and midnight-morning over Campo Grande. Some discrepancies were also found for the F-region peak height (hmF2) near the geomagnetic equator during times of F3 layer occurrences. IRI has underestimated both foF2 and hmF2 over equatorial and low latitude sectors during evening-nighttimes, except for Jicamarca where foF2 values were overestimated.

  3. Non-differentiable minimax fractional programming with generalized [alpha]-univexity

    NASA Astrophysics Data System (ADS)

    Jayswal, Anurag

    2008-04-01

    In this paper, we study a non-differentiable minimax fractional programming problem under the assumption of generalized [alpha]-univex function. In this paper we extend the concept of [alpha]-invexity [M.A. Noor, On generalized preinvex functions and monotonicities, J. Inequalities Pure Appl. Math. 5 (2004) 1-9] and pseudo [alpha]-invexity [S.K. Mishra, M.A. Noor, On vector variational-like inequality problems, J. Math. Anal.

    In this paper, we study a nondifferentiable minimax fractional programming problem under the assumptions of [alpha]-invex function. In this paper we utilize the concept of [alpha]-invexity [M.A. Noor, On generalized preinvex functions and monotonicities, J. Inequalities Pure Appl. Math. 5 (2004) 1-9] and pseudo-[alpha]-invexity [S.K. Mishra, M.A. Noor, On vector variational-like inequality problems, J. Math. Anal. Appl. 311 (2005) 69-75]. We also introduce the concept of strict pseudo-[alpha]-invex and quasi-[alpha]-invex functions. We derive Karush-Kuhn-Tucker-type sufficient optimality conditions and establish weak, strong and converse duality theorems for the problem and its three different dual problems.

    This work was conducted to assess the impacts on workplace and ambient air quality due to release of sulfur dioxide (SO(2)) into the atmosphere at Al-Noor production station, located in southern desert of Sultanate of Oman. The SO(2) is released because of oxidation of H(2)S to SO(2) on flaring of H(2)S rich off gas at the Al-Noor. In the first phase of the study, CALPUFF modeling system was used to predict the ground level concentrations of SO(2) emissions from the flare stacks. The evaluation of the modeling system was carried out by comparing the predicted results with that of the measured. In the second stage of the study, the estimated results were compared with the air quality standards/guidelines set by Omani regulatory authorities as well as by World Health Organization (WHO). It was concluded on the basis of current study that the sensitive individuals in the workplace of the Al-Noor could experience adverse health effects due to short-term exposure of SO(2).

    Infants with low birth weights are provided with hospital nutrition support to enhance their survivability and body weights. However, different hospitals have different nutrition support formulas. Therefore, the effectiveness of these nutrition support formulas should be investigated. To assess the effect of hospital nutrition support on growth velocity and nutritional status of low birth weight infants at Al-Noor hospital, Saudi Arabia. A cross-sectional study was conducted between October, 2010 and December, 2012. Three hundred newborns were recruited from Al-Noor Hospital in Makkah city, Saudi Arabia. Infants were selected according to their birth weights and were divided equally into three groups; (i) Low Birth Weight (LBW) infants (1501- 2500 g birth weight), (ii) Very Low Birth Weight (VLBW) infants (1001-1500 g birth weight) and (iii) Extremely Low Birth Weight (ELBW) infants (< 1000 g birth weight). Data were collected at birth and at discharged. Infants' weights were recorded and growth velocity was calculated. Some biochemical tests and mineral levels were measured. Body mass index values of VLBW and ELBW groups were lower (p < 0.05) than LBW group. The growth velocity of infants in all groups ranged between 8.7 to 10.2 g/kg/d with no differences (p > 0.05) were observed among groups. Serum calcium, phosphorus and potassium levels at discharge were higher (p < 0.05) than that at birth for ELBW and VLBW groups; while sodium level decreased in ELBW group to be within normal ranges. Albumin level was improved (p < 0.05) in ELBW group. Health care management for low birth weight infants in Al-Noor Hospital was not sufficient to achieve normal growth rate for low birth weight infants, while biochemical indicators were remarkably improved in all groups.

    The purpose was (a) to study the effect of an 8-week Finnish military basic training period (BT) on physical fitness, body composition, mood state, and serum biochemical parameters among new conscripts; (b) to determine the incidence of overreaching (OR); and (c) to evaluate whether initial levels or training responses differ between OR and noOR subjects. Fifty-seven males (19.7 ± 0.3 years) were evaluated before and during BT. Overreaching subjects had to fulfill 3 of 5 criteria: decreased aerobic physical fitness (VO2max), increased rating of perceived exertion (RPE) in 45-minute submaximal test at 70% of VO2max or sick absence from these tests, increased somatic or emotional symptoms of OR, and high incidence of sick absence from daily service. VO2max improved during the first 4 weeks of BT. During the second half of BT, a stagnation of increase in VO2max was observed, basal serum sex hormone-binding globulin (SHBG) increased, and insulin-like growth factor-1 and cortisol decreased. Furthermore, submaximal exercise-induced increases in cortisol, maximum heart rate, and postexercise increase in blood lactate were blunted. Of 57 subjects, 33% were classified as OR. They had higher basal SHBG before and after 4 and 7 weeks of training and higher basal serum cortisol at the end of BT than noOR subjects. In addition, in contrast to noOR, OR subjects exhibited no increase in basal testosterone/cortisol ratio but a decrease in maximal La/RPE ratio during BT. As one-third of the conscripts were overreached, training after BT should involve recovery training to prevent overtraining syndrome from developing. The results confirm that serum SHBG, cortisol, and testosterone/cortisol and maximal La/RPE ratios could be useful tools to indicate whether training is too strenuous.

    The redox state of Earth's convecting mantle, masked by the lithospheric plates and basaltic magmatism of plate tectonics, is a key unknown in the evolutionary history of our planet. Here we report that large, exceptional gem diamonds like the Cullinan, Constellation, and Koh-i-Noor carry direct evidence of crystallization from a redox-sensitive metallic liquid phase in the deep mantle. These sublithospheric diamonds contain inclusions of solidified iron-nickel-carbon-sulfur melt, accompanied by a thin fluid layer of methane ± hydrogen, and sometimes majoritic garnet or former calcium silicate perovskite. The metal-dominated mineral assemblages and reduced volatiles in large gem diamonds indicate formation under metal-saturated conditions. We verify previous predictions that Earth has highly reducing deep mantle regions capable of precipitating a metallic iron phase that contains dissolved carbon and hydrogen.

    One of the objectives of the present investigation is to identify classes of equivalent mixed models and reduced/selective integration displacement models for curved shell structures. A second objective is concerned with the identification of the spurious modes exhibited by various mixed models and their equivalent reduced integration displacement models. The merits of using mixed models are also evaluated. The mixed elements developed in the current investigation differ from those presented by Noor and Hartley (1977) by the fact that the stress resultants are discontinuous at interelement boundaries and, therefore, are eliminated on the element level. The high accuracy and effectiveness of the elements developed is demonstrated by means of numerical examples, taking into account three geometrically nonlinear problems of shallow shells.

    Date (Phoenix dactylifera L.) fruit soluble phenolics composition and anti-atherogenic properties were examined in nine diverse Israeli grown varieties. Ethanol and acetone extracts of 'Amari', 'Barhi', 'Deglet Noor', 'Deri', 'Hadrawi', 'Hallawi', 'Hayani', 'Medjool', and 'Zahidi' fruit were analyzed for phenolics composition by RP-HPLC and tested for anti-atherogenicity by measuring their effects on LDL susceptibility to copper ion- and free radical-induced oxidation, and on serum-mediated cholesterol efflux from macrophages. The most frequently detected phenolics were hydroxybenzoates, hydroxycinnamates, and flavonols. Significant differences in phenolics composition were established between varieties as well as extraction solvents. All extracts inhibited LDL oxidation, and most extracts also stimulated cholesterol removal from macrophages. Considerable varietal differences were measured in the levels of the bioactivities. Also, acetone extracts exhibited a significantly higher anti-atherogenic potency for most varieties. The presence of soluble ingredients with anti-atherogenic capacities in dates and the possible involvement of phenolics are discussed.

The tissue of the uterus is presented by a linear viscoelastic model with two major time constants. A proper user defined function is developed and incorporated in the simulation software, to represent the model. The geometry of the uterus is separately modeled. It is found that viscoelasticity of the tissue which can be controlled and altered by change the concentration can directly affect its internal pressure. It is also observed that the pressure decreases as the moisture of the tissue is increased. The study is repeated for several practical conditions and parameters pertaining to the viscoelasticity of the tissue are evaluated.

    Surgery for advanced cancer of the hypopharynx is a complex issue. Surgical intervention needs to take into consideration the resultant quality of life, in particular fundamental functional outcomes such as speech and swallowing. The aim of this study is to look at these long-term functional outcomes, following pharyngolaryngectomy and free jejunal reconstruction. A total of 19 patients, each undergoing a pharyngolaryngectomy with free jejunal graft was included. Each had a primary tracheoesophageal puncture for insertion of an indwelling voice prosthesis for speech. Functional outcomes of speech and swallow were assessed by a qualified speech pathologist. The impact on patients' quality of life was assessed under 4 domains: impairment, disability, handicap, and well being. The mean time period to follow-up was 4 years. Eighteen of the 19 patients were tolerating an oral diet, with one patient reliant on percutaneous endoscopic gastrostomy feeds. Seventeen patients (89%) were assessed as either having either no--or only a mild degree--of dysphagia, with no evidence of aspiration. Of the 19 patients, 15 were utilizing tracheosophageal speech for communication with 11 (73%) having no--or only a mild degree--of dsyphonia. Patients assessed as having no evidence of dysphagia or dysphonia also reported reduced levels of handicap and distress compared with patients experiencing any degree of dysphagia (P = 0.46) or dysphonia (P = 0.01). While rates of pharyngolaryngectomy increase, most patients have a poor long-term prognosis, heightening the significance of postoperative outcomes. The results of this study highlight the importance of speech and swallow outcomes, and demonstrate the direct correlation between these functions and resultant quality of life.

    A major debate in medical ethics is the request for futile treatment. The topic of medical futility requires discrete assessment in Iran for at least two reasons. First, the common principles and foundations of medical ethics have taken shape in the context of Western culture and secularism. Accordingly, the implementation of the same guidelines and codes of medical ethics as Western societies in Muslim communities does not seem rational. Second, the challenges arising in health service settings are divergent across different countries. The Quranic concept of idle (laghw) and its derivatives are used in 11 honorable verses of the Holy Quran. Among these verses, the 3rd verse of the blessed Al-Muminūn Surah was selected for its closer connection to the concept under examination. The selected verse was researched in the context of all dictionaries presented in Noor Jami` al-Tafasir 2 (The Noor Collection of Interpretations 2) software. "Idle" is known as any insignificant speech, act, or thing that is not beneficial; an action from which no benefit is gained; any falsehood (that is not stable or realized); an entertaining act; any foul, futile talk and action unworthy of attention; loss of hope; and something that is not derived from method and thought. The word has also been used to refer to anything insignificant. The notes and derived interpretations were placed in the following categories: A) Having no significant benefit (When medical care does not benefit the patient (his body and/or soul and his life in this world and/or the Hereafter), it is wrong to proceed with that medical modality; B) Falsehood (Actions that fail to provide, maintain, and improve health are clearly futile); C) Unworthy of attention (An action that neither improves health nor threatens it is wrong and impermissible).

    Exact measurement of quality of life (QOL) in schizophrenia patients for evaluation of the patient's deterioration and also to assess the efficacy of therapeutic Interventions has become a daily task, which requires accurate assessment tools. This study was aimed to assess the psychometric properties of a Persian version of schizophrenia QOL scale (SQLS) as a common transcultural instrument. One hundred and fifty schizophrenia patients who referred to Psychiatric Clinic in Noor Hospital (Isfahan, Iran) have been selected using simple sampling method. Aside with SQLS, short form-36 general health (SF-36) and World Health Organization QOL-brief-26 (WHOQOL-BREF-26). Questionnaires were completed by the cases for determination of correlation coefficients. The data were analyzed using descriptive statistics, factor analysis, Cronbach's coefficient alpha, Pearson correlation coefficient by Statistical Package for Social Sciences software, version 18 (SPSS-18). Total reliability of the questionnaire was reported by using Cronbach's coefficient alpha 0.84, reliability of individual relationships subscales was 0.91, signs 0/87, symptoms 0/72 and motivation/energy 0/61. Correlation coefficients of SF-36 with a total scale of SQLS and correlation coefficient of WHOQOL-BREF-26 with a total scale of SQLS were acceptable. Exploratory factor analysis using varimax rotation identified four principle components (interpersonal relationship, symptoms, signs, motivation, and energy), which will determine QOL at 52.7% variance. Persian version of the SQLS can be used as a simple, reliable and valid tool in Iranian population.

    Background Understanding sexual behavior before marriage is relatively rare in the East, especially in Islamic societies, because sexuality is a sensitive subject for many Muslims. Objectives The purpose of this study was to identify premarital sexual intercourse-related individual factors among Iranian adolescents. Patients and Methods This qualitative study was performed on 30 students of Payame Noor university of Shiraz city, Iran, in 2014. The study sample includes male and female university students selected using the convenience sampling method. Semistructured interviews were used to collect data. All interviews were conducted by the researcher in a comfortable atmosphere and carried out without the presence of others. Each interview lasted between 30 - 20 minutes. Interviews continued until data saturation occurred. Data were analyzed using the qualitative content analysis method. Participation in the study was voluntary by obtaining an informed consent. Results The study included 30 participants, 56.6% (n = 17) males and 43.4% (n = 13) females. The age range of study, participants was from 19 to 25 years of age. Data analysis showed that three main categories extracted in shaping premarital sexual intercourse in adolescents: health beliefs, religious-spiritual beliefs, and character. Conclusions This study can help find a culturally appropriate intervention to delay sexual initiation and prevent sexual behavior before marriage in adolescents and young adults. The results of the present study have both experimental and theoretical implications for future research. Finally, this study is a form of shared experience that can help similar studies.

    Research conducted over PCOS by various groups in the world indicated the effect of Metformin on PCOS. Previous studies suggest that Glucophage by reducing hyper-insulinemia is clinically useful in the treatment of polycystic ovary syndrome (PCOS). Our Objective was to observe the role of Glucophage in treating infertility of polycystic patients within three months in Group A and six months in Group B patients. Another aim was to assess the decrease in hyper-insulinemia and Leptin levels by Glucophage in our population. This study was carried out at the Department of Obstetrics and Gynaecology, Pakistan Institute of Medical Sciences, and Noor Specialised Clinic Islamabad, from Oct 2004 to Apr 2008. One hundred and seventy women in Group A and 145 in Group B fulfilling the clinical and biochemical criteria for PCOS were enrolled. Glucophage was started at an oral dose of 500 mg/day and maintained at 1500 mg for 3 months or 6 months in both Groups. Besides ultrasonography, serum FSH, LH, fasting insulin, fasting blood sugar, glucose insulin ratio, Quantitative Insulin Sensitivity Check Index (QUICKI) and leptin levels were performed. After three months in Group A and six months in Group B these criteria were again assessed. After 3 and 6 months of Metformin therapy, significant reduction in biochemical parameters was observed such as fasting glucose, insulin and leptin. Data were analysed using SPSS by paired t-test and ANOVA. Six months treatment with Glucophage proved to be better option for infertile PCOS.

    This study was designed to compare the effects of intranasal (IN) and intravenous (IV) administration of naloxone in patients who had overdosed on opioids. This randomized clinical trial study was conducted in the Department of Poisoning Emergencies at Noor and Ali Asghar (PBUH) University Hospital. One hundred opioid overdose patients were assigned by random allocation software into two study groups (n = 50). Both groups received 0.4 mg naloxone: one group IN and the other IV. Outcomes included change in the level of consciousness (measured using a descriptive scale and the Glasgow Coma Scale (GCS)), time to response, vital signs (blood pressure, heart rate and respiratory rate), arterial blood O2 saturation before and after naloxone administration, side-effects (agitation) and length of hospital stay. Patients who had been administered IN naloxone demonstrated significantly higher levels of consciousness than those in the IV group using both descriptive and GCS scales (p < 0.001). There was a significant difference in the heart rate between IN and IV groups (p = 0.003). However, blood pressure, respiratory rate and arterial O2 saturation were not significantly different between the two groups after naloxone administration (p = 0.18, p = 0.17, p = 0.32). There was also no significant difference in the length of hospital stay between the two groups (p = 0.14). Intranasal naloxone is as effective as IV naloxone in reversing both respiratory depression and depressive effects on the central nervous system caused by opioid overdose.

    The Holy Quran is a religious book of Muslims. In many verses of Quran, various foods are discussed. It seems that limited studies were performed on identification the nutritional verses and their frequencies in the Holy Quran. Therefore, the aims of present study were to establish a numerical model system for studying nutritional verses of Quran, determination of verses with nutritional concepts and frequency of foodstuffs in the Holy Quran. In this descriptive analytical study, "Ghamoos e Quran" and "Vazheyab" online softwares were used to determine the nutritional keywords in Quran. For searching, translating, and interpretation of verses, "Noor-e-Jami Tafasir version 2.1"; "Zekr" and "Pars Quran"softwares were applied. Sixty-four nutritional keywords and 257 nutritional verses were identified. Findings indicated that aliment/foods, eating, water/drinking words, and their derivatives are repeated 171, 109, and 131 times in the Holy Quran, respectively. According to the Holy Quran, except Haram foods (pork meat, wine, carrion meat, blood, and meat of animals not slaughtered properly in the Islamic manner), all foods are tayyeb (lawful). The Holy Quran contains many foodstuffs and verses with nutritional concepts and it recommends eating varied and balanced diet.

    Background: Psychopathological perfectionism is often correlated with obsessive compulsive eating disorders. Objectives: The purpose of this study was to investigate perfectionism in people with high traits of obsessive compulsive and eating disorder characteristics. Materials and Methods: This study was an expo fact research. The statistical population of the research comprised of male and female undergraduate students at Tabriz and Sarab branches of Payam- e- Noor University, Tabriz Islamic University and Azarbaijan Shahid Madani university in the academic year 2012 - 2013. A group of 640 university students, using the stratified random sampling method were screened by the obsessive compulsive inventory and the eating attitude test, then a group of 143 participants with high obsessive compulsive traits with another 137 participants with high eating disorder characteristics were selected and assessed with the Perfectionism Inventory. Data were analyzed using one way analysis of variance. Results: The results showed that perfectionism and related negative dimension are more commonly found in people with high obsessive-compulsive traits than eating disorder characteristics (P < 0.02). The results showed the highest contribution of maladaptive perfectionism in predicting obsessive-compulsive features and pathological eating attitude. Also, no difference was found between the two groups in terms of negative perfectionism. Conclusions: The greater association of perfectionism with symptoms of obsessive-compulsive is consistent with its phenomenological feature. Fear of failure may motivate the behavioral components of perfectionism that aim to focus on careful checking, reassurance seeking and excessive consideration before making a decision. PMID:26576174

    The objectives of this correlational study were to explore whether the oral health-related quality of life (ohrqol) of adolescents/young adults with cleft lip/palate (CL/P) relates to their own and their parents' satisfaction with treatment and treatment outcomes. Data were collected using mailed surveys from 30 parents and 27 patients who completed CL/P treatment. Patients' ohrqol was assessed with the Michigan Oral Health-Related Quality of Life (MOHRQoL) Scale, treatment satisfaction with Kiyak's Post-Surgical Patient Satisfaction Questionnaire, and satisfaction with treatment outcomes with Noor and Musa's Cleft Evaluation Profile. Overall, patients reported a positive ohrqol. Their satisfaction scores ranged from low to high. Patient and parent treatment satisfaction was related, while their outcome satisfaction did not correlate. Patients' MOHRQoL scores correlated with parent and patient treatment satisfaction and parents' outcome satisfaction. Patients' MOHRQoL scores did not correlate with patients' outcome satisfaction. The patients' level of discomfort was strongly correlated with patients' and parents' treatment satisfaction and parents' outcome satisfaction. In conclusion, regardless of outcome satisfaction, young patients with CL/P report a quite positive ohrqol after treatment completion. There is a clear relationship between the ohrqol of these patients with CL/P and their own as well as their parents' treatment satisfaction assessments.

    The parasite Entamoeba histolytica is a cause of diarrhea in infants in low-income countries. Previously, it was shown that tumor necrosis factor alpha (TNF-α) production was associated with increased risk of E. histolytica diarrhea in children. Interleukin-25 (IL-25) is a cytokine that is produced by intestinal epithelial cells that has a role in maintenance of gut barrier function and inhibition of TNF-α production. IL-25 expression was decreased in humans and in the mouse model of amebic colitis. Repletion of IL-25 blocked E. histolytica infection and barrier disruption in mice, increased gut eosinophils, and suppressed colonic TNF-α. Depletion of eosinophils with anti-Siglec-F antibody prevented IL-25-mediated protection. In contrast, depletion of TNF-α resulted in resistance to amebic infection. We concluded that IL-25 provides protection from amebiasis, which is dependent upon intestinal eosinophils and suppression of TNF-α.IMPORTANCE The intestinal epithelial barrier is important for protection from intestinal amebiasis. We discovered that the intestinal epithelial cytokine IL-25 was suppressed during amebic colitis in humans and that protection could be restored in the mouse model by IL-25 administration. IL-25 acted via eosinophils and suppressed TNF-α. This work illustrates a previously unrecognized pathway of innate mucosal immune response. Copyright © 2017 Noor et al.

    Obstructive sleep apnea (OSA) is a common sleep disorder affecting quality of life. The aim of this study was to evaluate the perception of Quality of Life (QOL) in patients with OSA by means of World Health Organization Quality of Life (WHOQOL-BREF) instrument. This study was conducted on adult patients with sleep problems referred to Noor Sleep Lab for an overnight sleep study. Subjects were assessed for QOL using WHOQOL-BREF questionnaire. The Epworth sleepiness scale (ESS) was also employed to assess excessive daytime sleepiness (EDS). Baseline characteristics, ESS, and measured QOL are reported and their correlations with QOL were examined. Out of 502 patients included in the study, 62.7 % had moderate to severe OSA. The mean score of QOL in physical domain was significantly lower compared with normative population data. While AHI did not show any correlation with quality of life, mean O(2) was weakly correlated with physical domain. Among the baseline characteristics, BMI and ESS were negatively correlated with physical and mental domains. Findings of this study show the impairment in quality of life related to physical functioning in patients with obstructive sleep apnea. Our study further supports the lack of association between AHI and QOL.

    Four different aerobic mixed consortia collected from basins of wastewater streams coming out of dying plants of Crescent Textile (CT), Sitara Textile (ST), Chenab Fabrics (CF) and Noor Fatima Textile (NF), Faisalabad, Pakistan were applied for decolorization of Drimarene Orange K-GL, Drimarene Brilliant Red K-4BL, Foron Yellow SE4G and Foron Blue RDGLN for 10 days using the shake flask technique. CT culture showed the best decolorization potential on all dyestuffs followed by ST, NF and CF, respectively. CT could completely decolorize all dyes within 3-5 days. ST cultures showed effective decolorization potential on Foron Yellow SE4G and Drimarene Brilliant Red K-4BL but complete color removal was achieved after 4 and 7 days, respectively. NF culture showed 100% decolorization efficiencies on Foron Yellow SE4G and Foron Blue RDGLN but it took comparatively longer time periods (5-7 days). Where as, the NF culture had decolorized only 40% and 50% of Drimarene orange and red, respectively, after 10 days. CF caused complete decolorization of Foron Blue RDGLN and Drimarene Brilliant Red K-4BL after 4 and 8 days, respectively but it showed poor performance on other two dyes.

    To evaluate hypersensitivity to Dermatophagoides pteronyssinus (D. pteronyssinus) and Dermatophagoides farinae (D. farinae) in pediatric patients with asthma, and the use of acaricides. This is a randomized controlled trial in 82 asthmatic children. They were recruited and evaluated for severity and chronicity according to the Global Initiative for Asthma Guidelines. The study was carried out in the Pediatric Allergy Clinic, Al Noor Hospital, Khalifa Branch, Abu Dhabi, United Arab Emirates between September 2008 and June 2010. Skin prick test (SPT) was performed including D. pteronyssinus and D. farinae, and for those who were sensitive to one, or the other. The therapeutic value of acaricides was evaluated by assessing the severity of asthma before and after their use. Approximately 81.7% of asthmatics were sensitive to house dust mites (HDM). Hypersensitivity was associated with the more severe and persistent asthma (p=0.029). The manifested severity of asthma was not HDM species-specific. There was a linear association between response of children to acaricides and increasing severity of asthma. Hypersensitivity to HDM is an important factor for persistent and severe forms of asthma. Acaricides can help control childhood asthma, and we recommend SPT as part of the routine work-up of patients with asthma to determine HDM sensitive patients that can benefit from acaricides use.

    A novel ovoid, phototrophic, purple non-sulfur bacterium was isolated in pure culture from a sample of sediment from an industrially polluted pond (Noor Mohammad Kunta) in Hyderabad, India. Strain JA234(T) was found to be Gram-negative and non-motile and grew photoheterotrophically with a number of organic compounds serving as carbon source/electron donor. Photo-organoheterotrophic and chemo-organoheterotrophic growth were demonstrated. Biotin and thiamine were required for growth of strain JA234(T). Phylogenetic analysis on the basis of 16S rRNA gene sequences showed that strain JA234(T) is most closely related to Rhodobacter azotoformans (97.3 % sequence similarity) and clusters with other species of the genus Rhodobacter of the family Rhodobacteraceae. However, DNA-DNA hybridization with Rba. azotoformans JCM 9340(T) showed a relatedness of only 31.3 % with respect to strain JA234(T). On the basis of 16S rRNA gene sequence analysis, DNA-DNA hybridization data and morphological and physiological characteristics, strain JA234(T) represents a novel species of the genus Rhodobacter, for which the name Rhodobacter ovatus sp. nov. is proposed. The type strain is JA234(T) (=JCM 14779(T)=CCUG 55049(T)).

    According to Beck theory, dysfunctional attitude has a central role in emergence of depression. The aim of this study was to determine contributions of dysfunctional attitude and general health index to depression. In this case-control study, two groups of subjects participated. The first group consisted of 65 patients with major depression and dysthymic disorder, who were recruited from Noor and Navab Safavi Psychiatry Clinics in Isfahan. The control group was consisted of 65 non-patient individuals who were accompanied or relatives of the patients and was matched with them based on age, sex and education. Both groups completed 26-item Dysfunctional Attitude Scale (DAS-26) and 28-item General Health Questionnaire (GHQ-28). Logistic regression and correlation methods were applied for statistical analysis. Logistic regression analysis showed that by an increase of one level in categorized DAS-26 scores and one score in the physical symptoms, anxiety, social dysfunction and depression subscales of GHQ-28 the risk of depression increase by 6.8, 1.6, 1.9, 3.7, 4.78 times, respectively. Capability of dysfunctional attitude and general health subscales to predict depression supports the Beck's cognitive diathesis stress theory of depression that dysfunctional attitude may be a predisposing risk factor for depression.

    Methamphetamine (METH) abuse and dependence present a major global problem. We investigated the efficacy of adding buprenorphine in reducing METH cravings during treatment with the Matrix program. This was a randomized, double-blind, controlled clinical trial of 40 men between the age of 18 and 40 years who were referred to the addiction treatment center at Noor Hospital from December 2012 to September 2013. All of the selected subjects participated in the Matrix program and were randomly assigned into 2 groups and given either buprenorphine or a placebo. A 4-month intervention program with buprenorphine or a placebo was arranged for each group. Demographic variables of the 2 groups, descriptive indices from the cocaine craving questionnaire-brief (CCQ-Brief), the ratio of urine tests positive for METH, and the frequency of drug complications were regularly evaluated in both groups every 2 weeks and, if not possible, by the third or fourth week. All analyses were performed by SPSS20 using analysis of covariance, χ, and t tests. The average of indices from the cocaine craving questionnaire-brief score, except the 2 initial measurements, was significantly lower in the intervention group in all measurements (P < 0.05). Apart from weeks 3 and 28, the ratio of positive tests was significantly different in all measurements in both groups (P < 0.05). Buprenorphine augmentation, in comparison with the placebo, significantly reduced the craving to use METH during treatment with the Matrix program.

    We tested whether corticosterone replacement causes increased sucrose drinking in adrenalectomized (ADX) rats compared to sham-ADX (sham) rats. ADX rats given high doses of corticosterone drank as much sucrose as sham rats, whereas at three lower doses of corticosterone, drinking was similar between groups and was only approximately 40% of that ingested by shams. Compared to sham rats, ADX rats drinking saline, or saline and saccharin, gain weight more slowly, contain less white adipose tissue, and have higher sympathetic outflow as assessed by uncoupling protein content in brown adipose tissue. Allowing sucrose as well as saline to drink restored all of these variables to normal in ADX rats with no- or low-corticosterone. All endpoints from sucrose-drinking ADX rats with no-or low-corticosterone were indistinguishable from those in water-drinking shams. By contrast, sucrose-drinking ADX rats that were given high doses of corticosterone exhibited the usual catabolic effects of corticosterone on body weight gain and, unlike sucrose-drinking shams, were obese. We conclude that (i) high corticosterone stimulates the potability of sucrose and inhibits sympathetic stimulation of uncoupling protein; (ii) sucrose, without corticosterone, normalizes metabolic deficits in ADX rats probably through actions mediated both peripherally and by the central nervous system; and (iii) ADX rats have a distinct sucrose appetite.

    A field experiment in collaboration with a private textile industry (Noor Fatima Fabrics Private (Ltd.), Faisalabad) was conducted to evaluate the effect of disposed water from bleaching unit, printing unit and end drain for improving growth and yield of wheat under saline sodic soil. Textile waste water along with canal water (control) was applied with and without liquid NPK fertilizer. The application of liquid NPK fertilizer with end drain waste water increased plant height, spike length, flag leaf length, root length, number of tillers (m(-2)), number of fertile tillers (m(-2)), 1000 grain weight, grain yield, straw yield and biological yield up to 21, 20, 20, 44, 17, 20, 14, 44, 40 and 41%, respectively compared to canal water (control). Similarly, the NPK uptake in grain was increased up to 15, 30 and 28%, respectively by liquid fertilizer treated end drain water as compare to canal water with liquid fertilizer. Moreover, concentration of different heavy metals particularly Cu, Cr, Pb and Cd was decreased in grains by application of waste water along with liquid NPK. The result may imply that waste water application along with liquid-NPK could be a novel approach for improving growth and yield of wheat in saline sodic soils.

    The last aim of this educational experience is the increase of the motivation of the students for the learning of the matters to giving as well as looking for the raising awareness, placing in the center the student and distinguishing the teaching for every group and specific case with different action plans for subjects and groups. This aim happens for achieving a major participation of the students in the way of developing and raising the matters (active subjects in the teaching), with a major follow-up of the teacher and a constant feedback with possibility of change in the exposition of the subjects to mold it to the characteristics of the groups of students. Besides the previous thing, one tries to obtain a manual of good practices in the classroom as well as a compendium of the actions undertaken before mistakes or aspects identified in the classroom and what results they have served us as tools for future or current teachers. Likewise, also one tries to improve the implantation of the systems of follow-up of the quality and also of coordination of professorship in the subject of Materials Science. The accomplishment of the questionnaires carried out by means of the controls of personalized response Educlick, equipment that was obtained by a Project of Educational Investigation (University of Salamanca), and that provides an experience of participation to the students. As for the teachers, it allows the application of measures of improvement and implementation of the qualit systems. It might extend to other Powers and Centers that are interested in similar experiences. The feedback has distinguished himself as one of the most powerful tools for the learning (Black and Williams, 1998). The investigation-action in the classroom (Avison et to, 1999; Contreras Perez and Arbesú García, 2008; Samian and Noor, 2012) supposes a methodology that allows to modify in time the teaching and to contribute this feedback to the pupils in every moment.

    Concentrating Solar Power (CSP), with an installed capacity of 4.9 GW by 2015, is a young technology compared to other renewable power generation technologies. A limited number of plants and installed capacity in a small challenging market environment make reliable and transparent cost data for CSP difficult to obtain. The International Renewable Energy Agency (IRENA) and the DLR German Aerospace Center gathered and evaluated available cost data from various sources for this publication in order to yield transparent, reliable and up-to-date cost data for a set of reference parabolic trough and solar tower plants in the year 2015 [1]. Each component of the power plant is analyzed for future technical innovations and cost reduction potential based on current R&D activities, ongoing commercial developments and growth in market scale. The derived levelized cost of electricity (LCOE) for 2015 and 2025 are finally contrasted with published power purchase agreements (PPA) of the NOOR II+III power plants in Morocco. At 7.5% weighted average cost of capital (WACC) and 25 years economic life time, the levelized costs of electricity for plants with 7.5 (trough) respectively 9 (tower) full-load hours thermal storage capacity decrease from 14-15 -ct/kWh today to 9-10 -ct/kWh by 2025 for both technologies at direct normal irradiation of 2500 kWh/(m².a). The capacity factor increases from 41.1% to 44.6% for troughs and from 45.5% to 49.0% for towers. Financing conditions are a major cost driver and offer potential for further cost reduction with the maturity of the technology and low interest rates (6-7 - ct/kWh for 2% WACC at 2500 kWh/(m2.a) in 2025).

    The risk of cell phone addiction is a social and psychological problem which has been proposed by psychologists, psychiatrists, and educational supervisors. The present study aimed to investigate the behavior of mobile phone addicts and mental health of university students of Shahrekord, Iran. This study was an applied research survey for the purposes of this study. The study population ýconsisted of all the students of Payame Noor University, Islamic Azad University, and University of Medical Sciences. The study population consisted of 296 students who were randomly selected from the target population. To collect data, two types of questionnaires were used, the Symptom Checklist-90-R(SCL-90-R) questionnaire, and the 32-point scale questionnaire of behavior associated with ýmobile phone use (Hooper and Zhou, 2007). Data analysis was performed using SPSS software, statistical analysis, frequency distribution, mean, one-way ANOVA, chi-square, and LSD (Least significance difference). The results showed that university students of Shahrekord, based on the six categories of mobile ýaddiction behaviors, were mostly placed in habitual behaviors (21.49%), addiction (21.49%), and intentional (21.49%) categories. By reviewing mental health indicators, it was found that students were affected with depressive disorder (17.30%), obsessive compulsive disorder (14.20%), and interpersonal sensitivity (13.80%). The results showed that there was a significant inverse relationship ýbetween mental health and habitual behaviors (r = -0.417), dependence (r = -0.317), addiction (r = -0.330), and incontinence (r = -0.309) in using mobile phone (P < 0.001). Survey results showed that with increased and improved mental health, the student's rate of cell phone addiction reduced.

    Context: Exact measurement of quality of life (QOL) in schizophrenia patients for evaluation of the patient's deterioration and also to assess the efficacy of therapeutic Interventions has become a daily task, which requires accurate assessment tools. Aims: This study was aimed to assess the psychometric properties of a Persian version of schizophrenia QOL scale (SQLS) as a common transcultural instrument. Settings and Design: One hundred and fifty schizophrenia patients who referred to Psychiatric Clinic in Noor Hospital (Isfahan, Iran) have been selected using simple sampling method. Subjects and Methods: Aside with SQLS, short form-36 general health (SF-36) and World Health Organization QOL-brief-26 (WHOQOL-BREF-26). Questionnaires were completed by the cases for determination of correlation coefficients. Statistical Analysis Used: The data were analyzed using descriptive statistics, factor analysis, Cronbach's coefficient alpha, Pearson correlation coefficient by Statistical Package for Social Sciences software, version 18 (SPSS-18). Results: Total reliability of the questionnaire was reported by using Cronbach's coefficient alpha 0.84, reliability of individual relationships subscales was 0.91, signs 0/87, symptoms 0/72 and motivation/energy 0/61. Correlation coefficients of SF-36 with a total scale of SQLS and correlation coefficient of WHOQOL-BREF-26 with a total scale of SQLS were acceptable. Exploratory factor analysis using varimax rotation identified four principle components (interpersonal relationship, symptoms, signs, motivation, and energy), which will determine QOL at 52.7% variance. Conclusions: Persian version of the SQLS can be used as a simple, reliable and valid tool in Iranian population. PMID:27512702

    The aim of this study was to determine the relationship between maternal serum C-reactive protein (CRP) levels in the first 20 weeks of pregnancy and later occurrence of preterm premature rupture of membranes and preterm birth. A prospective cohort study that measured maternal serum CRP levels in 778 pregnant women in the first half of pregnancy was performed in the city of Noor (north Iran), and included follow-up of patients up to time of delivery. Preterm premature rupture of membranes and preterm birth were defined as the occurrence of membranes rupture and birth, respectively before 37 weeks of gestation. Of the 778 pregnancies studied, 19 (2.41%) preterm premature rupture of membranes and 58 (7.3%) preterm births were seen. Median CRP levels in preterm premature rupture of membranes and preterm birth cases were much higher than in term deliveries (7 and 6.8 respectively vs 2.4 mg/L; 66.67 and 64.76, respectively vs 24.38 nmol/L). CRP levels >4 mg/L had statistically significant relationships with preterm premature rupture of membranes (OR 5.91, 95% CI 2.07-16.89) and preterm birth (OR 8.95, 95% CI 4.60-17.43). With a cut-off level of 4 mg/L of CRP, sensitivity, specificity, and likelihood ratios (LR(+) and LR(-) ) for preterm birth were 81, 70, 2.70, 0.28%, respectively, and for preterm premature rupture of membranes they were 79, 67, 2.41 and 0.31%, respectively. It seems that the inflammatory marker, CRP, can be used in the early stages of pregnancy to identify women at risk of experiencing preterm premature rupture of membranes and preterm birth. © 2012 The Authors.

    Poisoning is one of the most common medical presentations in a hospital. Hypoglycemic patients are at increased risk of toxicity. The purpose of this study was to compare capillary blood glucose and venous blood glucose measurements using glucometer against laboratory blood glucose in case of poisoned patients being in coma. During the 6-month study period, a random sample of 98 patients was admitted in the Department of Poisoning Emergency and Clinical Toxicology of Noor Hospital, Isfahan University of Medical Sciences, Iran from May 2010. Data collected included age, gender, poisoning reason, vital signs, and Glasgow Coma Scale. Capillary blood samples were obtained from the fourth fingertip of the non-dominant hand. t-Test, paired t-test, Pearson's correlation analysis, and one-way analysis of variance (ANOVA) were used for analysis. The mean of capillary blood glucose was 115.7 ± 50.2, of venous blood glucose measured by glucose meter was 117.8 ± 47.3, and of glucose measured in vitro was 115.8 ± 55.1. Mean of blood glucose showed no significant difference with the three mentioned methods. The correlation between capillary and intravenous blood glucose samples measured by glucometer was 0.93, between capillary blood glucose and in vitro measured venous blood glucose was 0.78, and between venous blood glucose measured by glucose meter and in vitro measured sample was 0.81. The mean of capillary and venous blood glucose levels measured by glucose meter, capillary and venous blood glucose levels measured in vitro, and venous blood glucose levels measured by glucose meter had no significant differences. Using venous blood sample and measuring the glucose level in it by glucometer is an acceptable and advisable method, and capillary blood glucose measurement by using glucometer is not recommended for patients in coma.

    The popularity and availability of herbal extracts has increased dramatically over the last decade, providing an inexpensive manner of self-medication. Although the efficacy of individual extracts is currently being studied intensively, research regarding complex mixtures is limited. Therefore, we evaluated the effects of three complex formulations, including BRC-301, a polyherbal extract; BRC-304, a mixture of vitamins, minerals, antioxidant enzymes, botanical extracts, and carotenoids; and BRC-306, a proprietary blend of Uncaria tomentosa (cat's claw) and Phytolens(®) on murine dendritic cells (DCs). We hypothesized that these formulations would decrease the inflammatory responsiveness and innate function of DCs. In order to address this hypothesis, we evaluated the effects of BRC-301, BRC-304, and BRC-306 on DC2.4 cells and assessed the effects of BRC-301 on bone marrow-derived DCs (bmDCs). Lipopolysaccharide (LPS) stimulation of DC2.4 cells and bmDCs induced production of nitric oxide (NO), TNF-α, and IL-6, a response that was modulated by concomitant treatment with non-cytotoxic concentrations of BRC-301. In contrast, only the production of NOor IL-6 by LPS-activated DC2.4 cells was affected by BRC-304 or BRC-306, respectively. Flow cytometric evaluation following concurrent BRC-301 and LPS treatment revealed an increased relative expression of CD11c, CD86, and CD54 on bmDCs and an increased frequency of bmDCs expressing MHC II. Finally, BRC-301 enhanced the uptake of fluorescein isothiocyanate-conjugated ovalbumin by bmDCs. Taken together, these results suggest that these commercially available formulations modulate the innate responsiveness of murine DCs and may enhance their ability to initiate T cell-mediated immunity.

    Objective To determine risk factors for multi-drug-resistant Acinetobacter baumannii (MDR-AB) nosocomial infections in intensive care units in a tertiary care hospital, Makkah, Saudi Arabia. Methods We performed a hospital-based, matched case–control study in patients who were admitted to Al Noor Specialist Hospital between 1 January 2012 and 31 August 2012. The study included cases of A. baumannii nosocomial infection and controls without infection. Controls were matched to cases by age and ward of admission. Results The most frequent site of infection was the respiratory tract (77.3%). Susceptibility to antimicrobial MDR-AB was 92.0% for ceftazidime and ciprofloxacin, while it was 83.3% for imipenem, 83.0% for trimethoprim, 79.0% for amikacin, and 72.7% for gentamicin. Multiple logistic regression of risk factors showed that immunosuppression (OR = 2.9; 95% CI 1.5–5.6; p = 0.002), clinical outcome (OR = 0.4; 95% CI 0.3–0.9; p = 0.01), invasive procedures (OR = 7.9; 95% CI 1.8–34.2; p = 0.002), a central venous catheter (OR = 2.9; 95% CI 1.5–5.6; p = 0.000), and an endotracheal tube (OR = 3.4; 95% CI 1.6–7.3; p = 0.001) were associated with MDR-AB. Conclusions Acinetobacter nosocomial infections are associated with admission to the ICU (Intensive care unit) and exposure to invasive procedures. PMID:28480813

    Background: Methamphetamine dependence lead to the compulsive use, loss of control, and social and occupational dysfunctions. This study aimed to compare the effect of valproate in reducing the craving in methamphetamine dependents. Materials and Methods: This is a randomized, double-blind, controlled clinical trial on 40 men of 18–40 years old referred to Noor Hospital during December 2012–September 2013 in Isfahan, Iran. The subjects participated in matrix program and randomly were divided into two groups of valproate and placebo. A 4-months program of intervention with valproate or placebo was arranged for each group. The rate of craving to methamphetamine and positive methamphetamine urine tests were evaluated in both groups every 2 weeks using cocaine craving questionnaire-brief (CCQ-Brief) and urine test. After the 4 months (active treatment with valproate and placebo), the drug was tapered and discontinued within 10 days, and patients were introduced to self-help groups and monitored regularly on a weekly basis over another 3 months. Collected data were analyzed with SPSS 20 using analysis of covariance repeated measure, Chi-square, and t-test. Results: CCQ score of the intervention group was significantly less than the placebo group (P < 0.001), except on weeks 1, 3, and 28. The ratio of a positive urine test for methamphetamine in the intervention group was significantly lower than the control group in all screenings except weeks 3 and 28. Conclusion: Adding valproate to matrix program in the treatment of methamphetamine dependence showed significant effect on the reduction of the craving to methamphetamine. PMID:27656618

    The prevalence of diabetes in the Middle East is increasing rapidly due to urbanization, reduced levels of physical activity, and a nutritional transition toward increased consumption of fats and refined carbohydrates. Preventive strategies are of paramount importance to stemming the tide. Portable touch-screen computer technology may hold an answer for alleviating the burdens of cost, time, and training that limit the implementation of diabetes risk screening and intervention, especially among refugees and other vulnerable populations. The Computer-Assisted Diabetes Risk Assessment and Education (CADRAE) Arabic-language intervention program is proposed as a model method for practicing proactive type 2 diabetes prevention in resource-limited settings of the Middle East that combines the efficiency of risk-score screening methods, the advantages of portable computer interface, and the spirit of brief motivational interviewing. This paper aims to describe the theory and novel design of CADRAE-introduced at the Noor Al Hussein Foundation's Institute of Family Health in January 2014-as well as discuss opportunities and challenges for its implementation and evaluation in primary or emergency care settings. Features of CADRAE are elucidated in detail, including development, translation, conceptual framework, theoretical basis, method of risk assessment, brief intervention style, definition of outcomes, requirements for implementation, and potential means of evaluation and quality improvement. CADRAE offers the first example of portable computer technology integrating diabetes risk screening with behavior change counseling tailored for an Arabic-speaking population of mostly refugees and could offer a valuable model for researchers and policy makers of the Middle East as well as other resource-limited settings.

    Background: Recently, the relationship between increased level of inflammatory mediators and occurrence of left ventricular failure in patients with kidney disease has been suggested. The present study attempted to assess relationship between inflammatory mediators and occurrence of left ventricular failure in patients with chronic kidney disease. Materials and Methods: This cross-sectional study was performed at Noor and Hazrat Aliasghar hospital in Isfahan between September 2012 to September 2013 on patients aged >19 years that referred for following their chronic kidney disease. Serum level of inflammatory parameters including C-reactive protein (CRP) and Interleukin-6 (IL-6) was measured using spectrophotometer. All patients were also assessed using M-mode echocardiography to determine left ventricular ejection fraction (LVEF). Results: The group with significant reduced LVEF showed lower GFR when compared to the normal LVEF group (40.73 ± 20.61% versus 44.43 ± 17.98%, P = 0.032). Comparing GFR across the three groups with normal LVEF (>55%), with mild LV dysfunction (LVEF: 45 – 55) those with significant LV dysfunction (LVEF < 45%) showed significantly lower GFR level in latter group compared with normal LVEF and mild LV dysfunction group (P = 0.026). Although the level of serum CRP was significantly higher in patients with significant left ventricular failure than other groups (P = 0.018). Conclusion: Inflammatory processes can potentially affect left ventricular function in patients with chronic kidney disease. In this regard, increased level of CRP may be a main factor for predicting severity of left ventricular failure in these patients. PMID:28299305

    To assess the nutritional status of low birth weight infants from Makkah area immediately after birth. The prospective study was conducted between October and December 2012 at Al-Noor Speciality Hospital, Makkah, Saudi Arabia, and comprised low birth weight infants who were divided into three equal groups according to their birth weight: group A (low birthweight1501-2500gm), group B (very low birthweight1001-1500gm), and group C (extremely low birth weight < 1000gm). Mothers who had delivered low birth weight infants were enrolled. Weight, length, head circumference, complete blood count, and blood tests were performed for all the infants under investigation. There were 300 infants in the study; 100(33.3%) in each of the 3 groups. Group C showed the lowest gestational age, length, and head circumferences (p< 0.05 each). No significant discrepancies were found in complete blood count results among the three groups (p>0.05). Normal serum phosphorus, potassium and magnesium levels and mild hypocalcaemia were observed in all infants. However, hypernatraemia was significantly evident (p< 0.05) for group C. All infants had hyperglycaemia and hyperbilirubinaemia. Albumin content decreased significantly (p< 0.05) as birth weight decreased. Groups B and C infants showed higher serum urea than group A infants (p< 0.05). Low newborn birth weight was related to the deteriorated nutritional status in terms of low anthropometric and abnormal biochemical measures. It was not possible to correlate the birth weight of the neonates to the parameters of the complete blood tests.

    To determine the efficacy of CT- guided transthoracic catheter drainage of intrapulmonary abscess considering success rate versus complications. This prospective study was carried out at radiology department of Al-Noor Specialist Hospital, Makkah, Saudi Arabia, from 1.1.2003 to 31.12.2005. Nineteen patients were selected for CT guided percutaneous drainage. Under CT guidance catheter placement was carried out using Seldinger technique. Nineteen patients with lung abscess were selected for the percutaneous CT guided drainage. Eight (42.105%) patients encountered no complications and lung abscess completely resolved with no residual cavity. Five (26.31%) patients developed pneumothorax, which was the most common complication of this study. These patients were kept under observation and followed-up by chest X-rays. Three (15.78%) had mild pneumothorax, which resolved and needed no further management, while two (10.52%) patients developed moderate pneumothorax and chest tube was inserted. Two (10.52%) patients developed mild haemoptysis which resolved within two hours, hence, no further management was required. Two (10.52%) patients had residual cavity and surgery was performed. Congenital cystic adenomatoid malformation (CCAM) was found in both cases. Two patients out of nineteen patients (10.52%) developed bronchopleural fistula and were operated. No mortality occurred during or after the procedure. CT allows optimal placement of catheter and hence enables safe and effective percutaneous evacuation of lung abscess. The morbidity and mortality of patients with percutaneous catheter drainage is lower than with surgical resection. Hence, CT guided drainage should be considered the first therapeutic choice in most patients of lung abscess who do not respond to medical therapy.

    To study the use of helical computed tomography 2-D and 3-D images, and virtual endoscopy in the evaluation of airway disease in neonates, infants and children and its value in lesion detection, characterisation and extension. Conducted at Al-Noor Hospital, Makkah, Saudi Arabia, from January 1 to June 30, 2006, the study comprised of 40 patients with strider, having various causes of airway obstruction. They were examined by helical CT scan with 2-D and 3-D reconstructions and virtual endoscopy. The level and characterisation of lesions were carried out and results were compared with actual endoscopic findings. Conventional endoscopy was chosen as the gold standard, and the evaluation of endoscopy was done in terms of sensitivity and specificity of the procedure. For statistical purposes, SPSS version 10 was used. All CT methods detected airway stenosis or obstruction. Accuracy was 98% (n=40) for virtual endoscopy, 96% (n=48) for 3-D external rendering, 90% (n=45) for multiplanar reconstructions and 86% (n=43) for axial images. Comparing the results of 3-D internal and external volume rendering images with conventional endoscopy for detection and grading of stenosis were closer than with 2-D minimum intensity multiplanar reconstruction and axial CT slices. Even high-grade stenosis could be evaluated with virtual endoscope through which conventional endoscope cannot be passed. A case of 4-year-old patient with tracheomalacia could not be diagnosed by helical CT scan and virtual bronchoscopy which was diagriosed on conventional endoscopy and needed CT scan in inspiration and expiration. Virtual endoscopy [VE] enabled better assessment of stenosis compared to the reading of 3-D external rendering, 2-D multiplanar reconstruction [MPR] or axial slices. It can replace conventional endoscopy in the assessment of airway disease without any additional risk.

Protocol registration PROSPERO CRD4201300444 5 (http://www.crd.york.ac.uk/prospero/). Study selection Randomised controlled trials (RCTs) comparing physical activity interventions with placebo, no/or minimal intervention in community-dwelling adults with symptomatic knee or hip osteoarthritis. Primary outcomes were change in physical activity or cardiopulmonary fitness after a minimum follow-up of 6 months. Data extraction Outcomes were measures of physical activity (self-reported and objectively measured) and cardiovascular fitness. Standard mean differences between postintervention values were used to describe the effect sizes. Results 27 984 titles were screened and 180 papers reviewed in full. Eleven RCTs satisfied inclusion criteria, total study population of 2741 participants, mean age 62.2. The commonest reasons for study exclusion were follow-up less than 6 months and no physical activity measures. The majority of included interventions implement an arthritis self-management programme targeting coping skills and self-efficacy. Seven studies used self-report measures, the pooled effect of these studies was small with significant heterogeneity between studies (SMD 0.22 with 95% CI −0.11 to 0.56, z=1.30 (p=0.19) I2 statistic of 85%). Subgroup analysis of 6–12 month outcome reduced heterogeneity and increased intervention effect compared to control (SMD 0.53, 95% CI 0.41 to 0.65, z=8.84 (p<0.00001) I2 of 66%). Conclusions Arthritis self-management programmes achieve a small but significant improvement in physical activity in the short term. Effectiveness of intervention declines with extended follow-up beyond 12 months with no significant benefit compared to control. The small number of studies (11 RCTs) limited ability to define effective delivery methods. Investigation of

    To compare the efficacy and outcome after cool phacoemulsification with conventional phacoemulsification techniques in terms of effective phacoemulsification time (EPT), wound size and operative complications along with other variables used for the technique. Randomized controlled clinical trial (RCCT). Ophthalmology Unit III, Sindh Government Lyari General Hospital and DUHS and Al-Noor Eye Hospital, Karachi, from January to December 2008. One hundred eyes with nuclear/cortico-nuclear cataract on LOCS III (Lens Opacities Classification System III) underwent phacoemulsification. Fifty eyes were randomized to have surgery by standard phacoemulsification technique and the other 50 eyes by cool phacoemulsification technique. Efficacy and outcomes were judged in terms of variables like effective phaco time, vacuum and power used, quantity of Ringer's lactate solution used and corneal burn. The results between the two groups were compared. Among the phaco variables, the vacuum used in all cases ranged from 100 to 200 mmHg in group A with mean vacuum of 145.3+29.6 and 300 to 350 mmHg with mean value of 325.8+14.5 in group B at phaco II (p < 0.001). There was a significant difference in amount of Ringer's lactate used during surgery with 100-180 ml in conventional phacotechnique as opposed to 75-150 ml in cool phacoemulsification (p < 0.001). EPT in group A was between 30 to 180 seconds with mean of 111.3+40.4 seconds while in group B, it ranged between 2 to 12 seconds with mean of 6.1+2.92 seconds (p < 0.001). Rate of intra operative complications was lower in cool phacoemulsification (2%) as compared with conventional technique (18%, p=0.008). Cool phacoemulsification is a safe technique to operate cataract of all grades. It seems to be superior as it reduces effective phaco time, less operative and postoperative complications and is, therefore, safer for the cornea especially with regard to corneal wound burn. However, significantly greater amount of vacuum is needed.

  9. Distribution system in Bangladesh spurs decline in growth.

    1992-01-01

    Fertility reductions in Bangladesh have contributed to a reduction in population growth from 2.5% between 1981 and 1991 to 2.3% in 1991. The average density of 800 persons/sq. km means competition for resources in a subsistence level economy. There is scarcity of land, food shortages, and an abundance of labor. Rapid socioeconomic development is not possible even with an average annual economic growth rate of 3.7% because of population growth. Birth control has doubled to 18.6% in 1991. Sterilization is no longer the primary means of contraception. Contraceptive usage increases are more widespread among young women who are spacing births. A recent study reports that fertility declines are due to increases in the expansion of family planning field workers over the past decade. Home distribution is considered compatible with sociocultural traditions. In 1990, there was 1 field worker/856 married women of reproductive age. 120 private voluntary organizations and the government provide contraceptive services. In 1989, 40% of pill and condom users obtained their supplies from commercial channels. This is possible because of the successful social marketing available through 130,000 commercial retail outlets. Nongovernmental organizations have also been given the freedom to operate independently from government programs. The International Center for Diarrheal Disease Research contributed to the contraceptive effort by field testing in Matlab, Aboynagar, and Sirajganj the introduction of door-to-door injectable contraception services and the building of satellite clinics. The information, education, and communications (IEC) activities also contributed to the 95.4% of women knowledgeable about at least 4 methods of contraception. Kantner and Noor reported that 14.4 million births were averted due to an increase in marriage age (from 16.3 years in 1974) to (17.7 years in 1989). Program efforts are being accelerated because of the 45% of the population that is presently under

    The thrust of this study was to examine some of the psycho-social risk factors for the recurrence of non-fatal suicide attempt in a sample of 1121 inmates admitted between April 2012 to June 2013 at the toxicology emergency ward, Noor Medical Centre, Isfahan, Iran. Out of the total participants, 240 of them reported history of suicide attempt and assumed the status of case group. The remaining 881 patients were admitted first their attempt and constituted the control group. Cases were compared to the controls with respect to select demographic features (i.e. age, sex, education, occupation, marital status, type of residence, and locale), current suicide attempt method, family history of suicide and drug abuse, history of psychiatric disorder, physical ailment and physical disability, substance abuse and alcohol use, psychiatric diagnosis, and recent life hassles (i.e. interpersonal, occupational, financial, medical, and home affairs). We used a structured interview schedule to interview the participants. Psychiatric diagnosis was based on the DSM-IV criteria. Data were computer analyzed using SPSS.21 and administering statistical analysis including Chi Square, t-student, and logistic regression. Demographic risk factors for recurrence of suicide attempts at the univariate level included occupational status [Crud odds Ratio (COR) = 0.53] and type of residence (COR = 1.40). Medical and psychiatric risk factors at the univariate level included substance abuse (COR = 1.97), physical ailment (COR = 1.76), alcohol use (COR = 1.84), psychiatric disorder (COR = 3.69), and history of suicide in the family of origin (COR = 1.86). Recent life hassles risk factors at the univariate level included financial constraints (COR = 1.46) and medical emergencies (COR = 3.48). A multivariate logistic regression model identified five variables (i.e. substance abuse, alcohol use, psychiatric illness, suicide in family, and medical emergencies) that were statistically

    Megaloblastic anemia (MBA), also known as macrocytic anemia, is a type of anemia characterized by decreased number of RBCs as well as the presence of unusually large, abnormal and poorly developed erythrocytes (megaloblasts), which fail to enter blood circulation due to their larger size. Lack of vitamin-B12 (VB12) and / or folate (Vitamin-B9, VB9) with elevated homocysteine is the key factor responsible for megaloblastic anemia. Prior studies have demonstrated the induction of apoptosis in these abnormal under-developed erythrocytes. However, it is not clear whether this apoptosis induction is due to elevated p53 level or due to any other mechanism. Furthermore, it is also not fully known whether decreased vitamin-B12 and / or folate are responsible for apoptosis induction mediated by p53 in pre-erythroblasts. Levels of serum VB9, VB12 and homocysteine in 50 patients suffering from MBA were compared with 50 non-megaloblastic anemia control subjects, who were referred by the clinicians for bone marrow examination for medical conditions other than MBA. Next, we have measured the p53 expression in the paraffin embedded blocks prepared from bone marrow biopsy, using immunohistochemistry, and the expression levels correlated with VB9 and VB12 levels. Out of 50 MBA patients 40 (80%) and 44 (88%) subjects had very low VB12 and VB9 levels respectively. In contrast, only 2 (4%) and 12 (24%) non-megaloblastic anemia controls, out of 50 subjects, had low VB12 and VB9 respectively. Correlating with low vitamin B9 and B12, the homocysteine levels were high in 80% cases. But, only 20% non-megaloblastic controls exhibited high homocysteine in plasma. Immunohistochemical analysis for p53 expression showed a significantly high level of expression in MBA cases and no-or very low-expression in control subjects. Our correlation studies comparing the VB12 and VB9 levels with p53 expression concludes unusually high p53 levels in patients suffering from VB12 and VB9 deficiency induced

    Objective The study aimed to evaluate the prevalence and predictor factors for compensated advanced chronic liver disease (c-ACLD) in patients with hepatitis Delta virus (HDV) infection. Methods This cross-sectional study included consecutive HDV-infected patients defined by positive anti-HDV. Patients with hepatitis C coinfection, liver transplantation or presence of conditions that limit liver (LSM) or spleen stiffness measurement (SSM) were excluded. Blood tests, abdominal ultrasound, SSM and LSM by transient elastography (FibroScan®) were performed at the same day. Alcohol consumption was quantified using the AUDIT score and c-ACLD was defined by LSM ≥ 15 kPa performed by an experimented operator blinded for clinical and laboratory data. Results 101 patients were eligible and few patients were excluded due to negative anti-HDV (n = 7), hepatitis C coinfection (n = 2), liver transplantation (n = 10) and limitation for LSM or SSM (n = 5). Therefore, 77 patients [61% male, age = 43 (IQR,36–52) years] were included. The prevalence of c-ACLD was 57% (n = 44/77). Patients with c-ACLD had a higher rate of detectable HBV viral load (p = 0.039), higher levels of transaminases, GGT, alkaline phosphatases, total bilirubin and INR (p<0.001 for all), as well as lower platelet count and albumin levels (p>0.001 for both) compared to those without c-ACLD. Patients with c-ACLD had higher SSM [65.2 (IQR,33.8–75.0) vs 21.8 (16.5–32.0) kPa; p<0.001] and higher splenic volume [475 (IQR,311–746) vs 154 (112–283) cm3; p<0.001] compared to those without. Detectable HBV viral load (>10 UI/ml), alkaline phosphatase (per IU/L) and GGT levels (per IU/L) were independently associated with c-ACLD in all multivariate models. Splenic volume [per cm3,OR = 1.01 (95%CI,1.01–1.02);p = 0.002], SSM [per kPa, OR = 1.04 (1.01–1.07);p = 0.012] and splenomegaly [yes vs no,OR = 28.45 (4.42–182.95);p<0.001] were independently associated with c-ACLD. Conclusions The prevalence of c

    Ball plasmoids (self-sustaining spherical plasmas) are a particularly unique example of a non-equilibrium air plasma. These plasmoids have lifetimes on the order of hundreds of milliseconds without an external power source, however, current models dictate that a ball plasmoid should recombine in a millisecond or less. Ball plasmoids are considered to be a laboratory analogue of natural ball lightning, a phenomenon that has eluded scientific explanation for centuries. We are searching for the underlying physicochemical mechanism(s) by which ball plasmoids and (by extension) ball lightning are stabilized using a variety of diagnostic techniques. This presentation will focus on optical emission spectroscopy (OES) of ball plasmoid discharges between 190-850 nm. The previous generation of OES measurements of this system showed emission from only a few atomic and molecular species, however, the energy available for the discharges in these experiments was limited by the size of the capacitor banks and voltages to which the capacitor banks were charged. We are capable of generating plasmoids at much higher energies, and as a result we are the first to report a very rich chemistry previously not observed in ball plasmoids. We have identified signals from species including NO A^{2}Σ^{+}→X^{2}Π, OH A^{2}Σ^{+}→X^{2}Π, NH A^{3}Π→X^{3}Σ^{-}, AlO A^{2}Π→X^{2}Σ^{+}, NH^{+} B^{2}Δ→X^{2}Π, W I, Al I, Cu I, and H_{α}, all of which have not yet been reported for this system. Analysis of the emission spectra and fitting procedures will be discussed, rotational temperatures of constituent species will be reported, and theories of ball plasmoid stabilization based upon these new results will be presented.

    This study was done to evaluate the frequency of iatrogenic gall bladder perforation (IGBP) in laparoscopic cholecystectomy and to determine its association with gender, adhesions in right upper quadrant and types of gall bladder. This retrospective descriptive study included 200 patients who underwent laparoscopic cholecystectomy for symptomatic cholelithiasis at Jamal Noor Hospital and Hamdard University Hospital, Karachi from January 2007 to January 2009. Video recording of all 200 laparoscopic cholecystectomies were analyzed for the IGBP. The different factors; sex of the patient, type of gall bladder, presence of adhesions in the right upper quadrant, timing of perforation, site of perforation, cause of perforation and spillage of stones were recorded. Data was entered and analyzed on SPSS 15. Pearson Chi Square test was applied to check the significance of these factors in IGBP where applicable. In this study there were 173 females and 27 male patients. IGBP occurred in 51 patients (25.5%) and among them 40(23.12%) were females and 11(40.74%) males. Statistical analysis failed to prove male gender a significant factor in the IGBP (p=0.051). Spillage of stones occurred in 23 patients (11.5% in total study population). In 32(18.49%) patients with chronic calculus cholecystitis IGBP occured while in other cluster of 27 patients suffering from acute cholecystitis, empyema & mucocele, 19(70.37%) had IGBP. Hence the condition of gall bladder (acute cholecystitis, empyema and mucocele) was proved statistically a significant factor in IGBP (p=0.000). Adhesiolysis in right upper quadrant was required in 109 patients in whom 31 patients (28.44%) had IGBP while in 91 patients in whom no adhesiolysis was required, 20 patients (21.98%) had IGBP. Statistically no significant difference was present regarding this factor (p=0.296). In total of 51 patients of IGBP, fundus of gall bladder was the commonest site of perforation in 21(41.18%), followed by body of gall bladder in

    The miswak, a traditional chewing stick for cleaning teeth, is made from the plant Salvadora persica. For religious and cultural reasons, miswak use is firmly established and widespread in Saudi Arabia and most other Muslim countries. Only recently has scientific evaluation of the miswak been undertaken. The aims of the thesis were: 1) to explore current oral hygiene habits and oral health awareness among urban Saudi Arabians in relation to age, gender and educational level (papers I and II); 2) to compare mechanical plaque removal and gingival health after miswak use and toothbrushing (paper III); 3) to compare the effect of miswak use and toothbrushing on subgingival plaque microflora (paper IV). In papers I and II, structured interviews were conducted with 1200 regular patients at two centres in the city of Makkah, providing dental care for university and military staff and their families, respectively. Consecutive patients were stratified according to gender and age, into 6 age groups from 10 to 60 years, with 50 male or female subjects in each group at each centre. Oral hygiene habits were correlated with the subjects' age, gender, and educational levels and analysed statistically by a generalized linear model and ANOVA. In papers III and IV, the subjects comprised 15 healthy Saudi Arabian male volunteers aged 21 to 36 years, attending the Dental Center at Al-Noor Specialist Hospital in Makkah City. A single-blind, randomised crossover design was used. The Turesky modified Quigley-Hein plaque and Löe-Silness gingival indices and digital photographs of plaque distribution were recorded in Paper III and in Paper IV plaque was sampled for DNA-testing. Inhibition zones around miswak material were examined on agar plates with Actinobacillus actinomycetemcomitans and the leukotoxicity of this bacterium was analysed in a bioassay with macrophages +/- miswak extracts (paper IV). In papers I and II, 73% of the subjects used a toothbrush and 65% used a miswak daily
