Selective methylation in the o-posn of phenols of formula (I): (where R1, R2, R3 and R4 (same or different)=H or satd 1-6C aliphatic hydrocarbon gps is carried out by reacting (I) with MeOH in the vapour phase at elevated temps using a 3-component CeO2-MgO-GeO2 catalyst or a ...
Workflow of high-dimensional analysis to characterize the heterogeneity of human CD4 TSCMcells. Arrows represent in vitro or in silico experiments, respectively. CCR7+CD45RO−CD27+CD4 T cells from young (n = 4) and elderly donors (n = 4) were index sorted and distributed as singl...
of woody plants, it has been suggested to contribute to cell wall mechanical properties in compression wood tracheids of several gymnosperm plant species19,20,21 and has been shown to possess load bearing properties in association with cellulose during the dynamic process of pollen tube growth22. ...
Polymethylbenzene (polyMB) and alkene cycles are considered as two main routes forming light olefins in the process of methanol to olefins (MTO); however, the contribution that each cycle makes to MTO is still unclear. In this work, density functional theory considering dispersive interactions (...

DNA fragments produced by mechanical shearing or enzymatic digestion have a mix of 5′ and 3′ protruding ends that need repair or conversion for ligation with the adapters. The following are key steps in the process to bl...
process to achieve the ethyl ester of n - (p - toluene - sulfonyl) - n - methyl - p - aminobenzoic acid from ethyl ester of n - (p - toluene sulfonyl) - p amino benzoic acid which performsmethylation in the environment of methanol use as methylation agent dimethyl sulphate at temperatu...
The water temperature went through an increasing process from 18℃ to 26℃ or to 30℃ respectively, with a rate of 2℃ per hour with heating rods. The initial time was set with the moment when the temperature reached 26℃ or 30℃, and then the water maintained at each treatment ...
by biological process (BP) enrichment, in GTPase regulator activity, nucleoside-triphosphatase regulator activity, etc. by molecular function (MF) enrichment (Fig. 2B–D). Figure 2 KEGG enrichment analysis (A) and GO analysis (B–D). Full size image...
sites that they are meant to silence is not well understood. However, researchers have determined that some of these DNMTs are part ofchromatin-remodeling complexesand serve to complete the remodeling process by performing on-the-spot DNA methylation to lock the closed shape of thechromatinin ...
