Differential regulation of insulin resistance and hypertension by sex hormones in fructose-fed male rats.
Differences in gender are in part responsible for the development of insulin resistance (IR) and associated hypertension. Currently, it is unclear whether these differences are dictated by gender itself or by the relative changes in plasma estrogen and/or testosterone. We investigated the interrelationships between testosterone and estrogen in the progression of IR and hypertension in vivo in i...
متن کاملMale steroid hormones and female preference for male body odor
It has been suggested that human scent works as a signal in mate selection, but the empirical evidence is scarce. Here, we examined whether women’s olfactory preferences for a man’s scent could be correlated with his testosterone, estradiol, or cortisol concentrations, and whether these preferences change along with the menstrual cycle. In line with previous studies, women in their most fertile...
متن کاملDifferential Effects of Male and Female Gonadal Hormones on the Intrathymic T cell Maturation
The study was undertaken to further elucidate a role of gonadal hormones in maintenance of normal thymocyte maturation and sexual dimorphism in the intrathymic T-cell development. Rats of both sexes were gonadectomized or sham-gonadectomized (controls) at age of 2 and 6 months, and 30 days later the thymus size, cellularity and thymocyte composition were evaluated. In both control and gonadecto...

چکیده برای دو دهه مطالعات بر روی فرصت تمهید و نقش آن در عملکرد گفتاری زبان آموزان نشان داده است که فرصت برای تمهید جهت انجام کار ((task عموما گفتار فراگیران را بهبود می بخشد (ellis, 2005). فرض بر این است که فرصت تمهید بار ذهنی را در خلال پردازش زبانی کاهش داده و به فراگیران اجازه میدهد تا به جنبه های مختلف زبان توجه کنند و این توجه تسهیل شده در عوض منتج به عملکرد کار موفق تر میشود. پژوهشگرا...
15 صفحه اولDifferential Sperm Priming by Male Sailfin Mollies (Poecilia latipinna): Effects of Female and Male Size
Recent interest in sperm competition has led to a re-evaluation of the ‘cheap sperm’ assumption inherent in many studies of sexual selection. In particular, mounting evidence suggests that male sperm availability can be increased by the presence of females. However, there is little information on how this interacts with male traits presumably affected by female mate choice, such as larger size....
