Testosterone induces apoptosis in cardiomyocytes by increasing proapoptotic signaling involving tumor necrosis factor-α and renin angiotensin system.

Numai utilizatorii înregistrați pot traduce articole

Anabolic androgenic steroids lead to cardiac complications and have been shown to exhibit proapoptotic effects in cardiac cells; however, the mechanism involved in those effects is unclear. The aim of this study was to assess whether apoptosis and the activation of caspase-3 (Casp-3) induced by

The correlation of interleukin 1 and tumour necrosis factor to oestradiol, progesterone and testosterone levels in periovulatory follicular fluid of in-vitro fertilization patients.

Numai utilizatorii înregistrați pot traduce articole

Data has accumulated suggesting reciprocity between cytokines and the reproductive system. The present study was performed in order to evaluate the correlation between interleukin 1 (IL-1) and tumour necrosis factor (TNF) concentrations in follicular fluid and its oestradiol, progesterone and

Physiologic testosterone therapy has no effect on serum levels of tumour necrosis factor-alpha in men with chronic heart failure.

Numai utilizatorii înregistrați pot traduce articole

Physiological testosterone therapy increases exercise capacity and reduces symptom scores in men with chronic heart failure (CHF). Tumour necrosis factor-alpha (TNF-alpha) exerts a significant pathologic activity in CHF, and physiologic testosterone replacement therapy is associated with reduced

Testosterone Prevents Cutaneous Ischemia and Necrosis in Males Through Complementary Estrogenic and Androgenic Actions.

Numai utilizatorii înregistrați pot traduce articole

Chronic nonhealing wounds are a substantial medical concern and are associated with morbidity and mortality; thus, new treatment strategies are required. The first step toward personalized/precision medicine in this field is probably in taking sex differences into account. Impaired wound healing is

Comparison of the role of testosterone and methyltestosterone in developing chloroform-induced renal tubular necrosis in mice.

Numai utilizatorii înregistrați pot traduce articole

The presence of testosterone is a prerequisite for the development of chloroform-induced renal tubular necrosis in mice. The purpose of this study was to check whether methyltestosterone exerts the same influence. Castrated males and females were treated with one of these compounds: those treated

Icariside II reduces testosterone production by inducing necrosis in rat Leydig cells.

Numai utilizatorii înregistrați pot traduce articole

The present study demonstrates that Icariside II (10, 20, and 40 µM) reduced Leydig cell testosterone production and cell viability in a concentration- and time-dependent manner. Hoechst 33342/propidium iodide staining indicated that no morphological changes in Leydig cell nuclear chromatin

Effects of testosterone on the prevention of T-2 toxin-induced adrenocortical necrosis in mice.

Numai utilizatorii înregistrați pot traduce articole

To evaluate the effect of exogenous testosterone on the development of T-2 toxin-induced necrosis of adrenal glands, mice were allotted to 3 treatment groups. Each treatment group contained castrated male, and castrated and sexually intact female mice. Each mouse in group 1 was given 0.16 mg

Modulation of goldfish testicular testosterone production in vitro by tumor necrosis factor alpha, interleukin-1beta, and macrophage conditioned media.

Numai utilizatorii înregistrați pot traduce articole

The relevance of immune-endocrine interactions to the regulation of testicular steroidogenesis in teleosts is virtually unexplored. The objectives of the present study were: 1) to investigate the effects of murine cytokines, tumor necrosis factor-alpha (TNFalpha) and interleukin-1beta (IL-1beta),

Effects of testosterone replacement and/or resistance training on interleukin-6, tumor necrosis factor alpha, and leptin in elderly men ingesting megestrol acetate: a randomized controlled trial.

Numai utilizatorii înregistrați pot traduce articole

BACKGROUND Megestrol acetate (MA) has been used to stimulate weight gain in elderly populations with the majority of the gain being adipose tissue. Significant inverse correlations have been reported between weight gain with MA and reductions in circulating the tumor necrosis factor (TNF) alpha

Exogenous testosterone modulates tumor necrosis factor-alpha and acute phase protein responses to repeated endotoxin challenge in steers.

Numai utilizatorii înregistrați pot traduce articole

Clinical responses to some disease agents differ between sexes and this dimorphism has been attributed to the immunomodulating effects of steroid hormones. Our objective was to determine in steers the effect of testosterone on circulating concentrations of immune response mediators (tumor necrosis

Cyproterone acetate-promoted prevention of renal cortical necrosis following testosterone and vasopressin administration.

Numai utilizatorii înregistrați pot traduce articole

Bilateral focal renal cortical necrosis was observed after vasopressin administration in rats pretreated for 10 days with testosterone phenyl propionate. When the androgen-receptor blocking-agent cyproterone acetate was administered together with the testosterone, the subsequent vasopressin

Direct and indirect effects of murine interleukin-2, gamma interferon, and tumor necrosis factor on testosterone synthesis in mouse Leydig cells.

Numai utilizatorii înregistrați pot traduce articole

It was recently observed that treatment of patients with a high dosage of human interleukin (IL-2) resulted in suppression of plasma concentrations of testosterone. A murine model was developed to assess the direct and indirect effects of murine IL-2 and the secondarily released cytokines, gamma

Delayed glans necrosis after circumcision: role of testosterone in salvaging glans.

Numai utilizatorii înregistrați pot traduce articole

Glans necrosis is a rare complication after circumcision and may occur secondary to cautery . The treatment of choice for glanular necrosis has not yet been established. The authors describe two cases of severe glanular ischemic necrosis that occurred after circumcision. The patients were

Tumor necrosis factor and interleukin-1 stimulate testosterone secretion in adult male rat Leydig cells in vitro.

Numai utilizatorii înregistrați pot traduce articole

The actions of two cytokines, tumor necrosis factor (TNF) and interleukin-1 (IL-1), on testosterone production by dispersed adult testis cells and purified Leydig cells in culture were studied. In one set of experiments, testis cells from adult (90-day-old) rats were enzymatically dispersed. In

Testosterone inhibits tumor necrosis factor-alpha-induced vascular cell adhesion molecule-1 expression in human aortic endothelial cells.

Numai utilizatorii înregistrați pot traduce articole

We investigated the effect of testosterone (T) on tumor necrosis factor-alpha (TNF-alpha)-induced expression of vascular cell adhesion molecule-1 (VCAM-1) in human aortic endothelial cells. Incubation of these cells with T resulted in a dose-dependent reduction in the expression, with this reduction
