Microglia-mediated neuroinflammation is recognized to mainly contribute to the pathogenesis of Parkinson's disease (PD). Tetrahydroxystilbene glucoside (TSG) has been proved to be beneficial for health with a great number of pharmacological properties. We examined the effects of TSG against dopamine...

Different strains of Lactococcus lactis ssp. cremoris hydrolyze peptides at different rates while the cell-free extracts of these strains all show the same or much higher rates of hydrolysis. These observations indicate that the uptake of peptides is the rate-limiting...

Citicoline or CDP-choline is a drug, made up by a cytidine 5'-diphosphate moiety and choline, which upon adsorption is rapidly hydrolyzed into cytidine 5'-diphosphate and choline, easily bypassing the blood-brain barrier. Once in the brain, these metabolites are used to...

The mechanisms by which the insulin-sensitive glucose transporter, GLUT4, is targeted and retained in a storage compartment near to the Golgi complex are poorly understood. Here we report that removal of the carboxyl-terminal acidic Pro(505)AspGluAsnAsp(509) sequence prevents the storage of...

A [FeFe]-hydrogenase model compound (µ-S(CH(2))(3)S)Fe(2)(CO)(4)(PMe(3))(2) [1] has been encapsulated in a low molecular weight (LMW) hydrogelator (Fmoc-Leu-Leu). Linear infrared absorption spectroscopy, gel melting and ultrafast time-resolved infrared spectroscopy experiments reveal significant contrasts in chemical environment and photochemistry between the encapsulated...
