reactive oxygen species (ros)plays an important role in sperm motility. the physiological generation at low concentration induces beneficial effects on sperm functions and plays a significant role in sperm metabolism. meanwhile, the excessive generation of reactive oxygen species can overwhelm protective mechanism and triggers changes in lipid and protein layers of sperm plasma membrane, which ...

hydrogen peroxide, an oxidizing agent used in surgery for its antiseptic properties, has been associated with life-threatening complications. we report a case of suspected gas embolism following irrigation of a tibial bone cyst with hydrogen peroxide in a five year-old boy under general anesthesia, who died despite resuscitative measures and a long stay in the intensive care unit.

the management of road traffic accident and the care of casualties  has undergone many changes in recent years. to provide an uniform and systematic approach the ems, firefighters, red cross, red crescent and other rescuers must be updated to reduce entrapment times, and mortality rates, over better organisation and a methodical approach. the rescuers should not attempt to administer medical fi...

The bulk modulus of a solid-like biomolecular condensate can make the indissoluble in conditions where liquid condensates dissolve. A phase diagram with minimum for indissolubility is obtained.

The paper reveals the influence of Li, B and composition metal contacts on processes resistive switching in memristive structures M/NC/D/M. After field exposure Cu/(Co50Fe50)Х(LiNbO3)100-Х/s-LiNbO3/Cu/sitall, Cu/(Co50Fe50)Х(LiNbO3)100-Х/d-LiNbO3/Cu/sitall Cu/(Co40Fe40B20)Х(SiO2)100-Х/d-LiNbO3/Cu/sitall at x < 13 at.% was detected a residual voltage (up to 16 mV) due electromigration Li ions,...

Taking cues from the concept of metabolomics in plants hot environments, we used a plant metabolite (carvacrol) as biosolvent to dissolve high molecular weight PHB biopolymer assisted by computational modelling unearth dissolution mechansim.
