Abstract The synthesis and structural characterization of the novel triruthenium nitrosyl cluster [Ru 3 (μ‐NO)(CO) 5 (μ‐H)(μ‐PBu t 2 ) (μ‐dppm)] ( is described. Compound was obtained by reaction 46‐valence electron (μ‐CO)(CO) 4 (μ ‐H)(μ‐H)(μ‐PBu 1 with nitric oxide on other hand in a more efficient way transfer reagent triphenylmethyl thionitrite (TTN). NO outlined dichloromethane whereas TTN r...

The front cover illustrates the diastereoselective formation of condensed heterocyclic ring systems by domino reaction sequences. dominoes toppling each other represent steps sequences, transformation initiating next one. mechanism cyclization is tunable choice reagent, affording four different systems. A novel mild nitroarenes to N-hydroxyindoles, in which deoxygenation carried out an intramol...

Organic modification of nano-SiO2 particles was performed with supercritical CO2 as solvent and a titanate coupling reagent NDZ-201 as the modification reagent. The surface of the nano-SiO2 particles was changed after modification by the titanate coupling reagent from hydrophilic to hydrophobic. IR and thermo-gravimetric analyses indicate that the interaction between the titanate coupling reage...

cacl2 treatment followed by heat shock is the most common method for artificial transformation. here, the cells were transformed using cacl2 treatment either with heat shock (standard protocol) or without heat shock (lab protocol) to comprehend the difference in transformation efficiency. the bl21 strain of escherichia coli (e. coli) was being susceptible using cacl2 treatment. some cells were ...

background: human papillomavirus (hpv) is responsible for the development of cervical neoplasia.  infection with human papillomavirus type 16 (hpv-16) is a major risk factor for the development of cervical cancer. the virus encodes three oncoproteins (e5, e6 and e7), of which, the e7 oncoprotein is the major protein involved in cell immortalization and transformation of the infected cells. the ...

Oroxylum indicum (L) Vent (O. indicum), a significant endangered medicinal plant, was transformed by the Rhizobium rhizogenes (R. rhizogenes) mediated transformation method using bacterial strain MTCC 532. For successful transformation, factors such as explant selection, Co-cultivation time, temperature for induced root development, technique, and antibiotic concentration were optimized. Variou...
