We study the dynamical properties of the system such as, atomic population inversion, the probability distribution of cavity-field, the Mandel parameter and atomic dipole squeezing. It is shown how the depth of the Morse potential can be affected by non-classical properties

of the system. Moreover, the temporal evolution of the Husimi-distribution function is explored.”
“A simple, sensitive and specific ultra-performance liquid BKM120 clinical trial chromatography/tandem mass spectrometry (UPLC-MS/MS) method was developed to determine the newly synthesized compound lipoic acid-niacin dimer (N2L) in plasma. Plasma samples were precipitated by methanol using tetrahydropalmatine as internal standard. Chromatographic separation was achieved on an Acquity BEH C-18 (2.1x50mm i.d., 1.7 mu m) column; the mobile phase contains methanol and buffer solution (water with 0.5% formic acid and 10mmol/L ammonium acetate). Multiple reaction monitoring selleck chemical (m/z 353.9148.6 for N2L and m/z 356.0192.0

for internal standard) was performed for detection and quantification. The method was validated to be rapid, specific, accurate and precise over the concentration range of 1-750ng/mL; N2L was not stable on the bench-top or during freeze-freeze-thaw cycles in plasma, but was stable in the stock solution and after preparation in the autosampler for 24h. The utility of the assay was confirmed by pharmacokinetic study of N2L in rats. Copyright (c) 2013 John Wiley & Sons, Ltd.”
“Metabolic changes in cells that participate in inflammation, such as activated macrophages and T-helper 17 cells, include a shift towards enhanced glucose uptake, glycolysis and increased activity of the pentose phosphate pathway. Opposing roles in these changes for hypoxia-inducible factor 1 alpha and AMP-activated protein kinase have been proposed. By contrast, anti-inflammatory cells, such as M2 macrophages, regulatory T cells and quiescent

memory T cells, have lower glycolytic rates and higher levels of oxidative metabolism. Some anti-inflammatory agents might act by inducing, through activation of AMP-activated protein kinase, a state akin to pseudo-starvation. Altered VX-689 research buy metabolism may thus participate in the signal-directed programs that promote or inhibit inflammation.”
“Dengue is a serious disease which has become a global health burden in the last decade. Currently, there are no approved vaccines or antiviral therapies to combat the disease. The increasing spread and severity of the dengue virus infection emphasizes the importance of drug discovery strategies that could efficiently and cost-effectively identify antiviral drug leads for development into potent drugs. To this effect, several computational approaches were applied in this work. Initially molecular docking studies of reference ligands to the DEN2 NS2B/NS3 serine protease were carried out.
