The thymus gland is a central lymphoid organ in which developing T cell precursors, known as thymocytes, undergo differentiation into distinct type of mature cells, ultimately migrating to the periphery where they exert specialized effector functions and orchestrate immune responses against tumor pathogens self-antigens. mechanisms supporting intrathymic are pleiotropically regulated by thymic ...

OBJECT To assess the effects of radiosurgery (RS) on the radiological and hormonal control and its toxicity in the treatment of pituitary adenomas. METHODS Retrospective analysis of 42 patients out of the first 48 consecutive patients with pituitary adenomas treated with RS between 1999 and 2008 with a 6 months minimum follow-up. RS was delivered with Gamma Knife as a primary or adjuvant trea...

obesity influences semen quality by hormonal imbalance. therefore, the aim of this study was to examine the effect of moderate and intensive aerobic training on obese male rats' reproductive function. 30 obese male rats were assigned to moderate training (n=10), intensive training (n=10) and control (n=10) groups. a matched control group of normal weight rats (n=10) were also recruited for...

(1) Dear Alice, I heard that while it's generally not advised to take antibiotics while on the birth control pill, it's still okay to take tetracycline. Is this true? (2) Dear Alice, I have heard many many times that antibiotics interfere with the effectiveness of oral contraceptives, but what about the depo-provera shot? Is there any research showing decreased effectiveness of Depo-Provera whe...

Recently, there has been a growing controversy, especially among evangelicals, over whether the birth control pill might have an abortifacient mechanism that sometimes causes early chemical abortions. An understanding of this controversy necessitates a clear definition of abortion, abortifacient, pregnancy, implantation, and especially personhood. If a zygote (fertilized egg) is not a person, t...

Hormones exert powerful influences on body fat distribution in humans. Studies under fully controlled conditions in vitro have indicated that cortisol and insulin facilitate lipid accumulation by expressing lipoprotein lipase (LPL). Growth hormone (GH) abolishes this and turns metabolism towards lipid mobilization. Testosterone and GH inhibit LPL and stimulate lipolysis markedly. Cortisol effec...

The hormonal control of protein deposition in animals is a highly integrated process. Consideration of this topic not only requires a study of hormonal interactions with target tissues but also the much more general topic of growth. Growth itself is a complex and integrated process and involves the formation and enlargement of many metabolic units. Obviously maximal protein deposition in an ani...
