Preventive effects of β-cryptoxanthin against cadmium-induced oxidative stress in the rat testis.

β-cryptoxanthin (CRY), a major carotenoid of potential interest for health, is obtained naturally from orange vegetables and fruits. A few research studies have reported that CRY could decrease oxidative stress and germ cell apoptosis. The purpose of this study was to examine the effects of CRY on acute cadmium chloride (CdCl 2 )-induced oxidative damage in rat testes.

GDF-9 and bFGF enhance the effect of FSH on the survival, activation, and growth of cattle primordial follicles.

This study aims to investigate the effects of follicle stimulating hormone (FSH) in combination with growth and differentiation factor-9 (GDF-9) or basic fibroblast growth factor (bFGF) on the activation, survival and growth of cattle primordial follicles. Ovarian tissues were cultured for 3, 7, 14, 22 days in α minimum essential medium (α-MEM) supplemented with FSH, FSH+GDF-9 or FSH+bFGF. Non-cultured and cultured ovarian fragments were processed for histological and TUNEL analysis.
