Women are twice as likely as men to suffer from depression and anxiety disorders and have an increased risk of onset during pe...
Recent studies have demonstrated that chronic stress promotes tumor growth, angiogenesis, and metastasis. In ovarian cancer, levels of the pro-angiogenic cytokine, interleukin 6 (IL-6), are known to be elevated in individuals experiencing chronic stress, but the mechanism(s) by which this cytokine is regulated and its role in tumor growth remain under investigation. Here we show that stress hor...
By using enzyme immunoassay techniques we have quantified the ovarian ecdysteroids during the 7-day cycle of olicyte maturation in Blattella germanica. Immunoreactive ecdysteroid levels were low on days O-2, increased to higher values on days 3-6, and peaked on day 7 (about 5 ng of 20-hydroxyecdysone equivalents per pair of ovaries). The predominant non-conjugated ovarian ecdysteroid detected b...
Introduction & Objective: The normal females reproductive function , needs hypothalamus-hypophysis-ovarian extensive hormonal messages. Primary hypothyroidism is characterized by reduced production and secretion of thyroid hormones. During follicular growth PCNA (Proliferating Cell Nuclear Antigen) and cycklin D complex play an important role in regulating cell proliferation .This study aime...
Introduction: Folliculogenesis is a cycle that any disruption in this cycle leads to disease. Treatment include Surgery, drugs and low-power lasers have been used as complementary. This study investigated photo-bio-stimulation effect of lasers (power<250 mW)) on folliculogenesis cycle in rats’ ovarian tissue in two wavelength 630 and 810 nm autonomously. Methods: Twenty-eight female Wistar rat...
background: snow trout (schizothorax pelzami) is an economically important species endemic in the north east of iran. objectives: the purpose of the present study was to investigate the reproduction cycle, time and temperature range of spawning. methods: the biometry of 243 fishes was measured and the ovarian development stages and plasma sex steroid hormones (testosterone, 17b- estradiol, pro...
background and objective: it is well known that menstrual period and ovarian function are affected by chemotherapy. although breast cancer is the most common cause of chemotherapy in women and ovarian hormones have very important direct and indirect effects on overall survival, disease-free survival, and life quality of patients, but few studies have addressed the frequency and related factors ...
objective: carthamus tinctorius l. (safflower) is a member of the asteraceae family which had been classified as a fertility regulator in the traditional medicine. the purpose of this study was to investigate its possible effects on the ovarian histomorphology and the levels of female reproductive hormones in the mice. materials and methods: sixty adult female balb/c mice were selected and rand...
The strongest association between FMR1 and the ovary in humans is the increased risk of premature ovarian failure (POF) in women who carry the premutation level of CGG repeats (55-199 CGGs). Research on the FMR1 gene has extended to other endpoints of relevance in the OB/GYN setting for women, including infertility and ovarian hormones. After reviewing the nomenclature changes that have occurre...
