Background: Interactions between RNA-binding proteins and RNA regulate RNA transcription during osteoporosis. Ferroptosis, a programmed cell death caused by iron metabolism, plays a vital role in osteoporosis. However, the mechanisms by which RNA-binding proteins are involved in ferroptosis during osteoporosis remain unclear.

Chronic/heavy exposure with ethanol is associated with risk of type 2 diabetes, due to β-cells dysfunction. It has been reported that ethanol can induce oxidative stress directly or indirectly by involvement of mitochondria. We aimed to explore the protective effects of the crocin/gallic acid/L-alliin as natural antioxidants separately on ethanol-induced mitochondrial damage.

Erastin, as an effective ferroptosis inducer, has received extensive attention in anti-tumor research. To develop an oral nanocarrier for high efficient loading hydrophobic erastin, here we prepared a fluoro-liposome (FA-3 F-LS) by the self-assembly of the folic acid modified fluorinated amphiphiles-FA-3 F conjugates. The hydrophobic component of three perfluorooctyl chains endows the FA-3 F-LSs with high stability to resist the harsh gastrointestinal tract condition.

Cephalosporin C (CPC) is a critical raw material for cephalosporin antibiotics produced by Acremonium chrysogenum. During fermentation, the oxygen supply is a crucial factor limiting the efficient biosynthesis of CPC. This study demonstrated that the addition of exogenous surfactants significantly increased the dissolved oxygen (DO) level, extracellular catalase content, and final CPC titer.

Purpose: Contemporary antiretroviral (ARV) medications are used by millions of men for HIV treatment worldwide. Limited data exist on their direct effect on sperm motility. This pilot study hypothesizes that in vitro exposure to ARVs will reduce sperm kinematic and motility parameter values.
