In the present study, we investigated the effects of exogenous application of NO-releasing donor sodium nitroprusside (SNP) and nitric oxide synthase inhibitor N G-nitro-l-arginine-methyl ester (l-NAME) on dehydration and drought tolerance of Poncirus trifoliata. The endogenous NO level was enhance...
The formazan that formed was dissolved during an overnight incubation with 10% sodium dodecyl sulfate-0.01 N HCl, and absorbance of the extracted chromogen was read spectrophotometrically at 540 nm. Intracellular Glutathione (GSH) Content Lung leukocytes (1 × 106) were collected after a 48 h ...
The synthesis of customized glycoconjugates constitutes a major goal for biocatalysis. To this end, engineered glycosidases have received great attention and, among them, thioglycoligases have proved useful to connect carbohydrates to non-sugar acceptors
Apolipoprotein E4 (APOE4) is the strongest known genetic risk factor for late-onset Alzheimer’s disease (AD). Conditions of stress or injury induce APOE expression within neurons, but the role of neuronal APOE4 in AD pathogenesis is still unclear. Here
The formations of O- or N-glucuronides by UDP-glucuronosyltrasferases (UGTs) are a common pathway in phase II drug metabolism and are considered as a detoxification process because these glucuronides are generally neither active nor reactive and are excreted rapidly from the body (4). However...
Data obtained suggest that lactone mycotoxins are more highly reactive with simple low-molecular-weight thiols (like GSH) than with complex ones (like Trx). Keywords: patulin (PAT); penicillic acid (PA); aflatoxin B1 (AFB1); maize; thioredoxin (Trx); thioredoxin reductase (Tr); glutathione ...
For example, Mo(CO)6 in aqueous acetonitrile, nickel chloride–sodium borohydride, or SmI2 was used as selective and mild reagent for N–O bond reduction in the presence of functionalities sensitive to other reducing agents (Scheme 38) <1998J(P1)3471, 2001OL1375, 2004TL8375, 2005TL3...
