Activity of physiological antioxidant system was decreased while lipid peroxidation was increased in blood, brain, paradontium and submaxillary salivary gland under conditions of acute pain-emotional stress, deficiency of antioxidants and of their combined effect. Deficiency of antioxidants caused the most pronounced stress-dependent activation of lipid peroxidation in parodontium; less distinct reactions were observed in brain and submaxillary salivary gland.

The cooling procedure markedly diminishes the quality of guinea pig () sperms, primarily because their membranes are highly susceptible to this process. This susceptibility triggers the generation of reactive oxygen species and free radicals, ultimately leading to lipid peroxidation in the sperm membrane. Surprisingly, there has been a lack of research on the use of Tris-based extenders to safeguard guinea pig sperm under refrigeration conditions.

Metabolic dysfunction-associated steatotic liver disease (MASLD) is a prevalent hepatic disorder worldwide. Arachidonic acid 15-lipoxygenase (ALOX15), an enzyme catalyzing the peroxidation of polyunsaturated fatty acids, plays a crucial role in various diseases. Here, we sought to investigate the involvement of ALOX15 in MASLD.

Cerebral ischemia-reperfusion (I/R) is a serious complication in patients with ischemic stroke. Senkyunolide A (SenA) can alleviate neuronal cell damage induced by cerebral I/R; however, the exact action mechanism remains unclear. An in vitro cellular injury model was established by inducing PC-12 cells with OGD/R.

Background: Sepsis-induced acute lung injury (ALI) is a severe clinical condition accompanied with high mortality. Tangeretin, which is widely found in citrus fruits, has been reported to exert antioxidant and anti-inflammatory properties. However, whether tangeretin protects against sepsis-induced ALI and the potential mechanisms remain unclear.

Background: Salinity stress impairs cotton growth and fiber quality. Protoplasts enable elucidation of early salt-responsive signaling. Elucidating crop tolerance mechanisms that ameliorate these diverse salinity-induced stresses is key for improving agricultural productivity under saline conditions.
