We review the history of the parallel tempering simulation method. From its origins in data analysis, the parallel tempering method has become a standard workhorse of physiochemical simulations. We discuss the theory behind the method and its various generalizations. We mention a selected set of the many applications that have become possible with the introduction of parallel tempering and we s...

A new ketone Isonitroso phenyl 2 propanone (HINP2P) has been synthesized by the reaction of Benzyl magnesium chloride with cadmium chloride and acetyl chloride. On subsequent treatment of Phenyl 2 propanone with namyl nitrite gives Isonitroso Phenyl 2 Propanone. The structure of these compounds has been confirmed by physiochemical and spectral data. A preliminary screening of these compounds fo...

The present review on some metal oxide nanoparticles used for pressure sensor, various metal oxide containing such as (SnO2, ZnO, Al2O3, WO3, Fe2O3, Ga2O3, TiO2 and SiC, ...etc.) responds detection pressure measure in kbar unit through oxygen activity as oxidation or reduction process of an integrated in devices sensor (MEMS, CMOS, MOX and MOXQ1D...etc.) that devices measuring of pressure as st...

Introduction Many intravenous (IV) drugs are required for complex and polypathologic critically ill ICU patients management. ICU nurses are daily confronted with drugs preparation and administration (solvent type and volume, infusion rate). They also have to deal with drugs physiochemical incompatibilities (PCI), especially as various IV medications are delivered via a single catheter lumen. PC...

treatment, biologically. Levobunolol HCl occuserts were prepared using hydroxypropyl methylcellulose (HPMC, 3% & 4%), poly vinyl pyrrolidone (PVP, 1%), methyl cellulose (MC, 1% & 2%) as polymers by solvent casting technique with objectives of increasing contact time, achieving controlled release, reduction in frequency of administration and greater therapeutic efficacy. Based on their physioche...

The aerial parts of Cissus quadrangularis L.Variant I and II are being used therapeutically for various ailments in indigenous system of medicine. Detailed pharmacognostical studies on the aerial parts were made. Variant I and II were analysed for their physiochemical, microscopical, fluorescent, qualitative and quantitative phytochemical, TLC and HPTLC characteristics. Quantitative variations ...

The physiochemical characteristics of the follicle-stimulating hormone (FSH) from whole sheep pituitary glands have been studied. The hormone behaves as a single protein in electrophoresis, diffusion, and ultracentrifugation. It has an isoelectric point at pH 4.5 and a molecular weight of 67,000 and contains 1.23 per cent hexose and 1.51 per cent hexosamine. The amino acid composition has also ...

Flux balance analysis (FBA) determines theoretical capabilities of metabolic networks using only stoichiometry and fundamental physiochemical capacity constraints. Metabolic networks reconstructed from annotated genome and literature. Capacity constraints include maximum uptake rates of oxygen and substrates such as glucose, acetate, and lactose. FBA determines optimal flux distribution for giv...

Four dammarane-type, three lupane-type, and an oleanane-type triterpenes named foliasalacins A(1) (1), A(2) (2), A(3) (3), A(4) (4), B(1) (5), B(2) (6), B(3) (7), and C (8) were isolated from the leaves of Salacia chinensis LINN. collected in Thailand. The structures of new triterpene constituents (1-8) were characterized on the basis of chemical and physiochemical evidence.

Xanthine oxidoreductase(XOR)plays an important role in many pathologies, such as tumors, chronic hypoxia, renal injury, hypertension and so on. In this article we mainly review the current research about the regulation of activity and gene expression of XOR, and its physiochemical property, organ distribution, changes in tumors and relation with the other diseases. We conclude that XOR is an im...
