Cell toxicity assessment in co-treatment to metalworking fluids and vibration: an in vitro study of occupational exposure setting.

This study was designed to study dual risk of MWFs and vibration according to exposure simulation of selected industry. Air samples of two types MWFs were evaluated according to NIOSH 5026. Vibration acceleration exposure was assessed based on the ISO 8041:2005 standard.

Let-7f microRNA negatively regulates hepatic differentiation of human adipose tissue-derived stem cells.

MicroRNAs (miRNAs) are noncoding RNAs involved in the regulation of the diverse biological processes such as metabolism, proliferation, and cell cycle, in addition to regulation of differentiation. So far, some miRNAs have been recognized to have important role in regulating hepatic functions. Statistically, let-7f has been revealed as a negative regulator of hepatic differentiation.
