The appropriateness of the interactions between Prolactin, gonadotrophins and testicular hormones ensures that normal spermatogenesis takes place in male. So this study is an attempt to classify male infertility depending on WHO criteria seminal changes evaluate serum Testosterone FSH LH levels participants, also determine association subtypes infertility. This involved three hundred infertile ...

Interleukin-6 (IL-6) is produced in granulosa cells under normal physiological conditions, including during ovulation. However, the roles of IL-6 in ovarian function, including regulation of LH receptor (LHR) expression in granulosa cells, have not been explored in detail. The aim of this study was to identify the mechanism underlying the effect of IL-6 on LHR expression in the granulosa cells ...

introduction: hot flashes (hf) and night sweats (ns) are due to vasomotor instability and could be recognized as cardiovascular risk markers. therefore, this study aimed to evaluate the relationship between vasomotor instability and severity of coronary artery disease (cad) in postmenopausal women.  materials and methods: this observational cross sectional study, was performed in chamran hospit...

We find statistical weaknesses in 20 RC4-like algorithms including the original RC4, RC4A, PC-RC4 and others. This is achieved using a simple statistical test. We found only one algorithm which was able to pass the test VMPC-R. This algorithm, being approximately three times more complex then RC4, is probably the simplest RC4-like cipher capable of producing pseudo-random output.

BACKGROUND While elevated levels of estradiol were predictive of mortality in critically ill surgical and trauma patients, their ability to predict outcome in nonsurgical patients has not been studied. We aimed to study the determinants of gonadotropin levels in acutely ill postmenopausal women with nonsurgical disease and the impact of changes in the gonadal axis on the outcome of these patien...

We found a statistical weakness in the Spritz algorithm designed by Ronald L. Rivest and Jacob C. N. Schuldt. For N = 8: Prob(output(x) = output(x + 2)) = 1/N + 0.000498. The bias becomes statistically significant (for N = 8) after observing about 2 outputs. Analogous bias occurs for N = 16. We propose an algorithm (VMPC-R) which for N = 8 produced 2 (31 million times more) outputs which remain...

toxic effects of trace elements upon the hypothalamic- pituitarytesticular axis and sex hormones have been reported in recent years. it is generally considered that cdcl2 poisoning causes histopathological changes in the testicles of male rats. little attention had been drawn to the possible toxic effects of cdcl2 on the ovary and female sex hormones. the purpose of the present study was to det...

We have previously shown that AMP-activated protein kinase (AMPK) can induce the resumption of meiosis in mouse oocytes maintained in meiotic arrest in vitro. The present study was carried out to determine whether AMPK activation is involved in hormone-induced maturation. Follicle-stimulating hormone (FSH) and the EGF-like peptide, amphiregulin (AR), are potent inducers of maturation in cumulus...

A cross-sectional study was conducted in 25 spray painters and 35 control subjects to evaluate neurobehavioral function, and thyroid and reproductive hormones profile. This study indicated higher prevalence of psychological and neurological symptoms, and clinical findings among spray painters when compared with controls. Levels of TSH were significantly (p<0.01) elevated in spray painters over ...

Kisspeptins have emerged as potent elicitors of gonadotropin secretion and, therefore, putative targets for pharmacological intervention. In this context, desensitization of gonadotropin responses to continuous administration of kisspeptins has begun to be characterized, but information so far available is mostly restricted to LH responses in males, whereas the similar phenomenon in females, of...
