the families of tgf-β proteins are the most important growth factors in the ovary for growth and differentiation of early ovarian follicles. three related oocyte-derived members of the transforming growth factor-β superfamily namely growth differentiation factor 9 (gdf9), bmp15 and bmpr-ib have been shown to be essential for follicular growth and ovulation. different mutations in the gdf9 gene ...
Mycoplasmas (class Mollicutes) are among the smallest microorganisms capable of self and autonomous life (1). The genus Mycoplasma includes a large number reduced species which in nature are associated with hosts either commensally or pathogenically General features of the class Mollicutes are small genome, lack of cell wall and low GC content.

Sheep are thought to have been one of the first livestock to be domesticated in the Near East, thus playing an important role in human history. The current whole mitochondrial genome phylogeny for the genus Ovis is based on: the five main domestic haplogroups occurring among sheep (O. aries), along with molecular data from two wild European mouflons, three urials, and one argali. With the aim t...
Stress hormones in Rocky Mountain bighorn sheep (Ovis canadensis canadensis), produced in response to environmental changes, road development, or high population density, may impact their immune systems to a threshold level that predisposes them to periodic, large-scale mortality. We compared the stress response to a novel environmental situation and repeated handling between bighorn sheep born...
When the Swiss National Park was founded, taking stock of fauna and flora a major goal. Various efforts were made to investigate insectivores rodents, but little published about findings. In this article I will analyse existing data in terms how small mammal has developed over last 100 years. The reveal that species are rare today then common ones quite numerous too. protection status meant for...
