Recent research has shown that catalytic hydropyrolysis is a promising method for production of liquid hydrocarbon fuels from lignocellulosic biomass. However, only limited been conducted within this field and the process still not well-understood. Based on available literature in our laboratories we identified most important reactions propose mechanistic model The influence hydrogenation catal...

Repair of DNA double-strand breaks (DSBs) is essential for genomic stability. The most common DSB repair mechanism in human cells, non-homologous end joining (NHEJ), rejoins broken DNA ends by direct ligation. It remains unclear how components of the NHEJ machinery assemble a synaptic complex that bridges DNA ends. Here, we use single-molecule imaging in a vertebrate cell-free extract to show t...

in the present work, impact of lewis acid (la) catalysts bf3, bcl3, and bbr3 on the kinetics andregioselectivity of 1,3-dipolar cycloaddition (1,3-dc) reaction between azidobenzene and acroleinwas theoretically studied using b3lyp/6-31g* level. our results indicate while the uncatalyzed 1,3-dc reaction under investigation takes place via a non-polar, non-regioselective, and lowasynchronous proc...

the mixed metal nanocomposite mgo∙al2o3∙zno has been prepared by coprecipitation method. the product was characterized by xrd. the average particle size was found to be 34.89 nm from xrd data. sem and sem-eds were studied for evaluating surface morphology and elemental composition. the ftir spectrum of prepared mixed metal nanocomposites mgo∙al2o3∙zno and mgo∙al2o3∙zno-curcumin were studied. th...

Phosphoinositide 3-kinase (PI3K) type IA is a heterodimer of a catalytic subunit, p110, and a regulatory subunit, p85. Here we show that p85 contains a GTPase-responsive domain and an inhibitory domain, which together form a molecular switch that regulates PI3K. H-Ras and Rac1 activate PI3K by targeting the GTPase-responsive domain. The stimulatory effect of these molecules, however, is blocked...
