Cytochrome P-450 (P450) catalyzes a wide variety of chemical reactions; however, its use for in vitro assays has several limitations, the most striking one is the use of the reduced nicotinamide adenine dinucleotide phosphate (NADPH) coenzyme. In this work, the P450 activity using NADP reduced by an anionic organosiloxane, commonly named silica hydride, was evaluated. The results showed that th...

Low refractive index thin films have generated substantial interest for use in optical devices particularly in Light Emitting Diodes (LEDs). Applications include photonic cavities, mirrors, etc. Such films are required to have precise control over both thickness and refractive index. Here, we investigate fabrication of Omni Directional Reflectors (ODRs) using nanoporous silica films. Sub-100 nm...

The elaboration and study of hybrid nanocomposites based on photoswitchable spin-crossover nanoparticles is reported. A silica polymeric gel is used as the confining medium to control the kinetics of nucleation and growth of a molecular spin-crossover prototype [Fe((mepy)(3)tren)](PF(6))(2). The precipitation of nanoparticles in the matrix is triggered by spin-coating of the doped gel on a conv...

Objective(s): To address the alarming problem of methicillin-resistant Staphylococcus aureus (MRSA), herein, a marine Streptomyces capable of producing an anti-MRSA compound has been studied.Materials and Methods: Strain MN41 was morphologically and physiologically characterized and then, molecularly identified using 16SrRNA analysis. To...

BACKGROUND Fumaria parviflora Lam. (Fumaraceae) is widely used in traditional as well as folkloric system of medicine from ancient. It is commonly known as 'Pitpapra' or 'Shahtrah' in Indian traditional system of medicine and used for treating numerous ailments like diarrhea, fever, influenza, blood purifier and other complications. The object of the present study was to evaluate the Antileishm...
