hypothalamic-pituitary–gonadal axis, which stimulates sex steroid production by increasing the secretion of gonadotropin-releasing hormone in the hypothalamus, which in turn stimulates the anterior pituitary to secrete gonadotropins, including luteinizing hormone (LH) and follicle-stimulating hormone (FSH)....
Sexual hormone synthesis and secretion are fundamental functions of the ovary. To determine the impacts of HFHS diet on ovarian function, the serum levels of sexual hormones were measured. The results showed that serum testosterone (T) levels of HFHS mice were significantly elevated than those of ...
who are sedentary and not currently using postmenopausal hormone replacement therapy. Postmenopausal status is defined as not having menstrual periods for at least 12 months. Being sedentary is defined as less than 2 hours per week of moderate sport activity (e.g., tennis, swimming, running, aero...
Specific hormone response and pituitary transcriptional regulation in the spawning and hatching stages of Muscovy duck [16]. Ovarian differentiation and maturation are integral to the complex process of gonadal development, which directly impacts fertility and reproductive success later in life. This study...
claimed that placebo acupuncture showed a similar improvement in the luteinizing hormone (LH) to follicle-stimulating hormone (FSH) ratio as fixed acupuncture in women with PCOS [11]. Due to there being no studies using placebo or no intervention as a comparator to determine the effect of ...
Our observations indicate that, in contrast to the theory on the role of vascular hormone receptors in preferential pick up of circulating hormones, there is no need to enhance selective pick up rather only prevent LH/CG transport to inappropriate sites. Abnormal placental LHR expression may play ...

line of defense is systemic acquired resistance (SAR) and induced systemic resistance (ISR). Plants often acquire systemic resistance to further infection after local infection with a pathogen [2,3]. This requires accumulation of the plant hormone salicylic acid in tissue distal to the site of in...
Meanwhile, many studies have shown that the RDI strategy was used during the growing stage of grape to improve red color development, by inducing the expression of genes involved in three major pathways that control the red color in grapes: anthocyanin biosynthesis, hormone biosynthesis, and the ...
Nonetheless, Ca2+ channels are unique because their activation also generates Ca2+ fluxes that change [Ca2+]i, a signal that controls migration, proliferation, growth, maturation, and hormone secretion. [Ca2+]i is also intimately linked to apoptosis and cytotoxic cell death. In the ovary, [Ca2...
