BACKGROUND The mini-pubertal period of almost six hours in neonatal male rats is thought to be an important stage in sexual development. OBJECTIVES The aim of this study was to investigate the effect of hormone inhibition during mini-puberty on testicular function in male rats. MATERIALS AND METHODS We measured serum testosterone (T), luteinizing hormone (LH) and follicle-stimulating hormon...

Paget´s disease of bone is a disorder characterized by disorganized remodeling. It´s occurrence in patients with end-stage kidney on renal replacement therapy rare. Here we report case an 80-year-old male peritoneal dialysis that presented high level alkaline-phosphatase mildly elevated parathyroid hormone and typical imaging findings localized to the pelvis. This fourth reported patient first ...

After infection of male mice with the plerocercoids (spargana) of Spirometra mansoni, serum levels of estrogen and testicular weight were analyzed by enzyme-linked immunosorbent assay (ELISA) and weighing machine, respectively. The serum level of estrogen increased progressively in infected mice compared with normal controls, whereas the testicular weight of infected mice decreased significantl...

The antennae of male Periplaneta americana acquire a large number of olfactory receptors at the adult stage. Electrophysiological methods (single unit and electroantennogram recording) show that a portion of the receptors added at the adult ecdysis are sex attractant receptors. Sex attractant receptors are not present in large numbers on larval and adult female antennae. The differentiation of ...

Background: There is a great concern for the possible adverse effects of cell phones and noise waves and it looks these wave effects on the individuals’ health. Thus, the present study was conducted to examine the effect of cell phone waves, severity noise, and simultaneous effect of cell phone waves and severity noise on sperm motility and sexual hormones in adult male rats. Materials and Meth...

Results of studies of hypophysectomized rats suggest that growth hormone serves as a final common mediator through which gonadal steroids and other modifiers of pituitary function alter the expression of gender-specific liver genes such as the sexually dimorphic pair of cytochrome P-450 isozymes, male-specific P-450h and female-specific P-450i. We tested the effects of growth hormone in a syste...
