Supply and protected different population of Litopenaeus vannamei subadult zero foster (F0) from difference provinces Iran

Nowadays, Litopenaeus vannamei are the most important species of farmed penaeidae shrimp in the world that is rapidly replacing native species in areas aquaculture. Due to demand increase for this species culture, shrimp displacement to different areas may be associated with some potential pathogens transferred to new areas farmed. Therefore, in this study were prepared bi-osecurity conditions for specific disease-free production of L. vannamei. Thereafter, three populations (Molokaei, High health and mix of Molokaei and High health) of the shrimp various reserves were detected base on origin and genetic indexes such as: observed heterozygosity, expected heterozygosity, allele frequency, coefficient inbreeding, genetic differentiation, genetic distance and genetic identity. On the other hand, epidemiological studies indicate non pathogens (viral, bacterial, fungal and parasitic) recognition of different populations selected in the quarantine salon. The bioassay results showed that the average weight and length of the populations of High health and Mix significantly greater than was a population of Molokaei. The shrimp populations were stocked in fiberglass tank (five ton) and were kept separated in the quarantine salon. During maintenance shrimp of populations in the quarantine salon were evaluated living and non-living pathogens with PCR, microbiology and biochemical methods. There is not any pathogens detection from shrimp populations stocking in the quarantine salon, so the shrimps were carried over to pond for broodstock culture of specific pathogenic free

Food Insecurity and some Associated Socioeconomic Factors Among Women with Metabolic Syndrome Referred to Clinics of Shiraz University of Medical Sciences

Abstract Background & aim: Food insecurity is defined as limited availability at all times to sufficient food of an active life. The aim of this study was assessing the food insecurity status and some associated socioeconomic factors in women with metabolic syndrome. Methods: The present cross-sectional study was conducted on 130 women between 30-60 years of age with metabolic syndrome referred to health centers of Shiraz University of Medical Sciences in 2011. Demographic and socioeconomic characteristics and food insecurity status were assessed using demographic and the 18-item Agriculture Organization of the United States of America household food security questionnaires, respectively. Data were analyzed by Chi-square, t-tests and Logistic Regression statistical tests. Results: Prevalence of food insecurity in the population was 69.2%. Logistic regression showed the independent variables affecting food insecurity in women with metabolic syndrome were household economic status, family size, and income respectively (P<0.05). Conclusion: Due to high rate of food insecurity in women with metabolic syndrome, perhaps reducing food insecurity is associated with reduced metabolic syndrome. Therefore, it is necessary to reduce food insecurity in the society, especially among women. Key words: Food Insecurity, Metabolic Syndrome, Wome

Sesame seed allergy: Clinical manifestations and laboratory investigations

Background: Plant-origin foods are among the most important sources of food allergic reactions. An increase in the incidence of sesame seed allergy among children and adults has been reported in recent years. The aim of this preliminary study was to investigate the prevalence, importance and clinical manifestations of sesame allergy among Iranian patients.Methods: In a cross-sectional survey, 250 patients with suspected IgE-mediated food allergies completed a questionnaire and underwent skin prick tests with sesame extract as well as cross-reacting foods (walnut, soya and peanut). Total IgE and sesame-specific IgE levels were measured. Patients with positive skin test reactions and/or IgE specific for sesame without clinical symptoms were considered sensitive to sesame. The patients who also had clinical symptoms with sesame consumption were diagnosed as allergic to sesame.Results: Of the 250 patients enrolled in this study, 129 were male and 121 female, with a mean age of 11.7 years. The most common food allergens were cow&apos;s milk, egg, curry, tomato and sesame. Sesame sensitivity was found in 35 patients (14.1%). Only five patients (2%) had sesame allergy. Sesame-sensitive patients had a significantly higher frequency of positive prick test to cross-reacting foods when compared to non-sensitized patients (p=0.00). The type of symptom was independent of gender and age of the patients, but urticaria and dermatitis-eczema were significantly more frequent in sensitized patients (p=0.008).Conclusions: This is the first study addressing the prevalence of sesame seed allergy in Iranian population. We found sesame to be a common and important cause of food allergy. The panel of foods recommended for use in diagnostic allergy tests should be adjusted

Sediment distribution pattern of the South Caspian Sea: possible hydroclimatic implications

Tue south Caspian subbasin extends from the foot of the Alborz Mountains to the deepest part of Caspian Sea. The Jithological background and tectonic setting of the study area primarily control the deposition ofthick sedimentary sequences of the basin, while hydroclimatic processes exert secondary impacts on the sediment distribution pattern. To evaluate past hydroclimatic changes, short sediment cores were retrieved from the continental shelfand upper slope of the south Caspian Sea and were treated for basic sedimentological properties and mineralogy. Tue results show that the sediments are composed of terrigenous, biogenic, and chemical components. The chemical component has a significant signature in the intemal structure of the sediment, which reflects degradation of organic material due to a succession of aerobic and anaerobic conditions. Aerobic conditions reflect the extreme climatic conditions that Jead to formation of well-oxygenated deep water in lowstands and extremely cold winters, when dense oxygenated water is allowed to touch the bottom sediments. The sediment distribution pattern demonstrates three distinctive areas in the southern continental margin with different organic matter and carbonate content. Pluvial inputs and wave hydrodynamics control the sediment properties and their distribution pattern in the upper shelf, while in deeper parts, the dynamics ofwater stratification and its temporal and Jong·term variations, relating to climate and water Jevel changes, detennine sediment composition. Overall, the sedimentary distribution pattem is a result of their sources in the catchment basin and the hydroclimate of the Caspian Sea
