Myelin basic protein (Mbp) is essential for both elaboration and maintenance of CNS myelin, and its reduced accumulation results in hypomyelination. How different Mbp mRNA levels affect myelin dimensions across the lifespan and how resident glial cells may respond to such changes are unknown. Her ...

The ratio between reduced and oxidized thiols, mainly glutathione and oxidized glutathione, is one of the biomarkers for the evaluation of oxidative stress. The accurate measurement of thiol concentrations is challenging because reduced thiols are easily oxidized during sample manipulation. Derivatization is commonly used to protect thiols from oxidation. ...
