Ovarian follicle selection is an important process impacting the laying performance and fecundity of hens, and is regulated by follicle-stimulating hormone (FSH) through binding to its receptor [follicle-stimulating hormone receptor (FSHR)]. In laying hens, the small yellow follicle (6-8 mm in diameter) with the highest expression of FSHR will be recruited into the preovulatory hierarchy during...

Purpose: To determine the regulation of the expression of osteoprotegerin and receptor activator of nuclear factor-kappa B ligand in human dental follicle cells by colony-stimulating factor-1, parathyroid hormone-related protein and bone morphogenetic protein-2. Materials and Methods: Primary human dental follicle cells were cultured. The fifth passaged human dental follicle cells were separate...

PURPOSE Two groups of girls with premature breast development were studied retrospectively. We tried to identify clinical, radiological, and hormonal parameters that could distinguish between a benign, nonprogressive premature thelarche and a true precocious puberty. METHODS The clinical outcome of 88 girls with breast enlargement before 6.1 years of age was analyzed. Taking into account the ...

OBJECTIVE Our purpose was to confirm the elevation of vaginal pH expected in patients with bacterial pathogens in premenopausal women and to examine the relationship of serum follicle-stimulating hormone and estradiol levels to vaginal pH in menopausal patients without and with hormone replacement therapy. STUDY DESIGN Vaginal pH was determined by phenaphthazine (Nitrazine) pH paper in 253 pa...
