Skeletal muscle atrophy involves and requires widespread changes in skeletal muscle gene expression and signaling pathway, resulting in excessive loss of muscle mass and strength, which is associated with poor prognosis and the decline of life quality in several diseases. However, the Tyrosinase is a metalloenzyme involved in o-hydroxylation of monophenols and oxidation of o-diphenols to o-quinones, with formation of brown or black pigments (melanines). Tyrosinase inhibitors are of great interest in medicine and cosmetics (skin whitening compounds), but also in food and beverage
Multiple sclerosis is a disease both of the CNS compartment in which a localized immune response occurs, and of the peripheral immune compartment. The causative agent is unknown, though viruses are suspected to be among the candidates. Here a hypothesis is proposed, that apart from viruses, also
Phthalate plasticizers are the most abundant man-made pollutants that have recently received wide-spread attention. There is uncertainty concerning the toxicity to humans. During the debate, scant attention has been paid to adverse effects at the molecular level which is the focus of this article.
MIF (macrophage migration inhibitory factor) plays a central role in the promotion and maintenance of the inflammatory response. It is implicated in a number of inflammatory diseases including sepsis, arthritis and colitis, and in diseases with an inflammatory component, such as atherosclerosis,
We collected experimental kinetic rate constants for chemical processes responsible for the development and progress of neurodegeneration, focused on the enzymatic and non-enzymatic degradation of amine neurotransmitters and their reactive and neurotoxic metabolites. A gross scheme of
The ability of small molecules such as urushiol, present as a wax on the poison ivy leaf surface, to cause allergic contact dermatitis (rhus dermatitis) has fascinated immunologists for decades. Current dogma suggests that these epicutaneously applied catechol-containing molecules serve as haptens
Dietary polyphenolics in fruits, vegetables, wines, spices and herbal medicines have beneficial antioxidant, anti-inflammatory and anticancer effects. However, we have observed that dietary polyphenolics with phenol rings were metabolized by peroxidase to form prooxidant phenoxyl radicals which, in
