Estimating gross primary productivity (GPP) at large spatial scales is important for studying the global carbon cycle and global climate change. In this study, the relationship between solar-induced c...
Protection of Bovine Mammary Epithelial Cells from Hydrogen Peroxide-Induced Oxidative Cell Damage by Selenium
selenomethionine selenoprotein synthesis arachidonic acid metabolism mitogen-activated protein kinase
2018/3/5
The uncontrolled release of arachidonic acid (ARA) and its metabolism by lipoxygenase (LOX) pathway can induce
and aggravate cellular oxidative stress. Selenium (Se) is an integral part of some antio...
