[ 1 ] - Estrogen treatment enhances neurogenic differentiation of human adipose derived stem cells in vitro

Objective(s):Estrogen is a sexual hormone that has prominent effects on reproductive and non-reproductive tissues. The aim of this study is to evaluate the effects of estrogen on the proliferation and neural differentiation of human adipose derived stem cells (ADSCs) during neurogenic differentiation. Materials and Methods: Isolated human ADSCs were trans-differentiated in neural induction med...

[ 2 ] - Evaluation of Antibiotic Resistance to Fluoroquinolones and Third Generation Cephalosporines in Iranian Clinical Isolates of Salmonella spp.

Salmonella enterica serotypes are one of the most important food borne pathogens and significant public health concerns around the world in humans and other animal species. A total of eighty three epidemiologically unrelated clinical isolates of Salmonella enterica serovars were subjected to antimicrobial susceptibility testing. Eleven isolates (13.1%) which were resistant to at least 4 groups ...

[ 3 ] - Human Virome

Viruses are dominant entities in the biosphere and parasitize all cellular life forms. The relative abundances of different classes of viruses are dramatically different between prokaryotes and eukaryotes. In marine, soil and animal-associated environments, virus particles consistently outnumber cells by one to two orders of magnitude. It is estimated that 10 quintillion (1030) viral particles ...
