OXIDATIVE STRESS AND REPRODUCTIVE FUNCTION: Oxidative stress in polycystic ovary syndrome.

In Brief: A genetic, epigenetic, and environmental association exists between oxidative stress (OS) and polycystic ovary syndrome (PCOS), expressed in a multifaceted clinical profile. This review summarizes and discusses the role of OS in the pathogenesis of PCOS syndrome, focusing on metabolic, reproductive, and cancer complications.

Abstract: Oxidative stress (OS), an imbalance between oxidants and antioxidants in cells, is one of many factors playing essential roles in the pathogenesis of polycystic ovary syndrome (PCOS).

Establishment of a Wisent () Germplasm Bank.

The wisent, or European bison (), belongs to the same family (Bovidae) as the American bison and domestic cattle. The wisent is the largest mammal in Europe, and is called the "Forest Emperor". The wisent is listed as "Vulnerable" on the IUCN Red List, and is protected by international law.

[TSG-6 protein and its role during maturation of ovarian follicles].

TSG-6 is an ~35 kDa glycoprotein belonging to the hyaluronan binding family. Its expression is induced as a result of an inflammatory condition and during ovulation. TSG-6 is a crucial protein engaged in extracellular matrix synthesis and organization of cumulus-oophorus-complexes (COCs) in preovulatory ovarian follicles.

Noninvasive fluorescent screening of microinjected bovine embryos to predict transgene integration.

Most transgenic domestic animals are generated by direct microinjection of DNA fragments into zygote pronuclei. It has generally been assumed that the majority of integration events should occur prior to the first round of chromosomal DNA replication. The aim of this study was to investigate the expression of GFP in bovine preimplantation embryos by using a gfp reporter gene consisting of chicken beta-actin promoter, the CMV-IE enhancer, gfp cDNA (EGFP) (732 bp) and rabbit beta-globin polyadenylation sequences.
