The influence of ß-dihydroxyl groups in the alkaline hydrolysis of glucosidic bonds is examined. In deriva­ tives of ß-D-glucopyranosides, all hydroxyl groups are trans to each other, and the alkaline elimination of sub­ stituted methyl ethers in positions C-2 and C-4 can be explained, in part, by assistance from neighboring trans a-hydroxyls. The rate of degradation of ethyl 2-2-methyl-ß-D-glu...

the objective of the present study was to evaluate the effect of metal mobilizing agents, ethelynediaminetetraacetic acid (edta) and salicylic acid (sa), on the accumulation and translocation of lead (pb) and nickel (ni) by fenugreek ( trigonellafoenum-graecum l . ) plants in contaminated soil. edta and sa were amended at 100 mm and 1.0 mm respectively. pb and ni content were estimated using ic...

Abstract The wide use of copper (Cu)-based fungicide has caused a stepwise accumulation Cu in the environment increasing occurrence phytotoxicity crops. To understand and alleviate this abiotic stress, maize seedlings were grown hydroponic solution with different combinations iron (Fe) forms. Results showed that sensitivity is related to nature form supplied chelate-exchange processes might inv...

Background Both short and long sleep duration were previously associated with incident dementia, but underlying mechanisms of this association remains unknown. This project aims to evaluate how self-reported its change over time associate (A)myloid, (T)au, (N)eurodegeneration (V)ascular neuroimaging markers Alzheimer’s disease (AD).
