We compared the expression of six genes in stomach tissue samples between healthy men and women in different age groups to study sexually dimorphic gene expression. Real-Time RT-PCR was used to compare gene expression between men and women. Our results showed that the expression of KCNQ1 (p = 0.01) was significantly higher in non-menopausal women compared to post-menopausal women. In addition, the expression level of the ATP4A gene in men under 35 years was significantly higher than in men above 50 (p = 0.026). Sexually and age dimorphic gene expression in some genes throughout life may affect gastric function. [ABSTRACT FROM AUTHOR]

Background: Plasmodium vivax is the most widespread species of Plasmodium in humans and causing about 80 million clinical cases annually. This study was undertaken to detect P. vivax in asymptomatic treated vivax malaria patients to trace latent/ sub-patent malaria infection. Method: The venous blood of all detected cases with P. vivax in Bashagard, Minab and Roodan Districts in Hormozgan Province from 2009 to 2010 was examined by microscopic and nested PCR methods for presence of the parasite. Results: In microscopic examination of peripheral blood smears, all samples were negative for the presence of the parasites. But, we detected two P. vivax related bands in the electrophoresis of the nested PCR products (120 bp). Conclusion: Following up the malaria cases after treatment by a combination of methods, or new diagnostics such as RDTs can be included in the priorities of malaria elimination program in Iran.

For investigation of correlation and path relations for soybean genotype under different levels of nitrogen starter and plant density an experiment was conducted in 2009-2010 growth season in Kermanshah, Iran. Results of correlation analysis showed that positive significant correlation was found for seed diameter and yield (r=1.00**) and for seed diameter and harvest index (r=0.54*). A negative significant correlation was found between oil and protein percent (r=-0.61**). Correlation coefficients between plant height and oil percent was negative and significant (r=-0.52*). Pod length correlated with protein content positively and significantly (r=0.70**) and correlated with oil content negatively and significantly (r=-0.61*). Path analysis for seed yield showed high positive direct effect of pod number per plant (0.51) and seed diameter (1.00) on seed yield. High positive indirect effects of characters on seed yield were found for pod number per plant through stem diameter (0.51) and 100-seed weight (0.51) and for seed diameter through harvest index (0.54). Based on path analysis results for oil percent of soybean genotypes high positive direct effects were found from seed diameter (1912.26), 100-seed weight (228.08), and number of pod per plant (121.57). Path analysis for protein percent showed that maximum positive direct effect was obtained from yield on protein percent (708.32). [ABSTRACT FROM AUTHOR]
