Effect of bromelain on sperm quality, testicular oxidative stress and expression of oestrogen receptors in bisphenol-A treated male mice.

Bisphenol A (BPA) as an endocrine-disrupting chemical (EDC) with low estrogenic activity increases oxidative stress and testicular damage. Bromelain is a mixture of different thiol endopeptidases and other components with many uses as a natural anti-inflammatory enzyme. The present study aimed to evaluate the effect of bromelain on male reproductive failure induced by BPA.

No mutations of FecB and FecG(H) in Iranian Lory sheep.

The Booroola fecundity gene (FecB) and growth differentiation factor 9 (GDF9) gene belong to the transforming growth factor β (TGF-β) superfamily. The mutations of these genes have additive effects on the prolificacy in sheep. The aim of the present study was to determine the possible mutations of FecB and FecG(H) genes in Lory sheep breed of the Lorestan province, Iran.

Genetic variation of ten microsatellite loci in Makui sheep of Iran.

The native breeds, because of their natural selection against harsh environment and adaptation to regional conditions are important to resource-poor farmers and pastoralists. The molecular characterization of genetic variation is a fundamental step to manage and conserve indigenous breeds. The aim of this study was to determine the genetic variation of Makui sheep.
