Site-Directed Mutagenesis of Recombinant Equine Chorionic Gonadotropin/Luteinizing Hormone: Differential Role of Oligosaccharides in Luteinizing Hormone- and Follicle-Stimulating Hormone-Like Activities.

Can fasting in the holy month of Ramadan affect on the levels of luteinizing hormone, follicle-stimulating hormone, and prolactin?

Adherence to the recommendations and obligations of Islam is of great importance in achieving a desirable lifestyle. Fasting in the holy month of Ramadan is one of the main principles of Islam, in which Muslims refrain from eating, drinking, oral medications, and smoking from Fajr (pre-dawn) to Maghrib (sunset). Islamic rules dictate that fasting is unacceptable if it causes harm to the health ...

Effects of lipoprotein, equine luteinizing hormone, equine follicle-stimulating hormone, and equine prolactin on equine testicular steroidogenesis in vitro.

A stallion testicular cell incubation system was developed and used to investigate the regulation of steroidogenesis in stallion testes. Cells isolated from testes of 2- to 4-year-old stallions (n = 6) were cultured for 12 hours in a defined medium with and without varying doses of lipoprotein, equine luteinizing hormone (eLH), human chorionic gonadotropin (hCG), equine follicle-stimulating hor...

Dissociation of human follicle-stimulating hormone. Comparison with luteinizing hormone.

Rat testis tissue receptor assays were utilized to study the kinetics of dissociation of human follicle-stimulating hormone (hFSH) and luteinizing hormone (hLH) under varying conditions of urea concentration and pH. In these competitive protein binding assays, 125I-hFSH and 125I-hLH were the radioligands and hormone dissociation was followed by a decrease in the ability of the dissociating horm...

Equine luteinizing hormone possesses follicle-stimulating hormone activity in hypophysectomized female rats.

The ability of equine luteinizing hormone (eLH) to promote follicular growth and maturation in hypophysectomized rats has been assessed. A single injection of equine LH has been shown to promote the growth of a large number of antral and preovulatory follicles. In addition, equine LH markedly increased serum estrogen levels and uterine weight. Furthermore, equine LH, like equine chorionic gonad...
