Hydroformylation of cyclohexene was studied with a catalyst system of Ru3(CO)12 and LiCl using H2 and CO2 instead of CO in NMP. The influence of H2 and CO2 pressures on the total conversion and the product distribution was examined. It was shown that increasing total pressure of H2 and CO2 promoted the reverse water gas shift reaction and increased the yield of cyclohexanecarboxaldehyde. Its hy...

Various protolytic residues in subunit I of aa3-600 quinol oxidase of the aerobic Gram-positive Bacillus subtilis were mutagenized to nonpolar residues. Two of the mutations, Y284F and K304L, impaired the bioenergetic function of the microorganism. The Y284F mutation suppressed the electron-transfer activity of quinol oxidase and altered its interaction with CO and H2O2, thus showing destructio...

The influence of roxithromycin (RXM) on the expression of co-stimulatory molecules, CD40, CD80 and CD86, was examined in vivo. When BALB/c mice were immunized intraperitoneally with two doses of dinitrophenylated ovalbumin (DNP-OVA) at 1 week intervals, intraperitoneal administration of RXM at 250 microg/kg once a day for 14 days strongly suppressed IgE contents in sera obtained from mice 22 da...

A system for assessing the anti-inflammatory effect of food factors was developed by establishing a co-culture system with intestinal epithelial Caco-2 cells (apical side) and macrophage RAW264.7 cells (basolateral side). In this system, the stimulation of RAW264.7 cells with lipopolysaccharide was followed by a decrease in transepithelial electrical resistance, which is a marker of the integri...

Electronic topology in metallic kagome compounds is under intense scrutiny. We present transport experiments ${\mathrm{Na}}_{2/3}\mathrm{Co}{\mathrm{O}}_{2}$ which the Na order differentiates a Co sublattice triangular $\mathrm{Co}{\mathrm{O}}_{2}$ layers. Hall and magnetoresistance (MR) data high fields give evidence for coexistence of light heavy carriers. At low temperatures, dominant carrie...

High-spin $d^7$ Co(II) compounds have recently been identified as possible platforms for realising highly anisotropic and bond-dependent couplings featured in quantum-compass models such the celebrated Kitaev model. In order to evaluate this potential, we consider all symmetry-allowed contributions magnetic exchange ideal edge-sharing bonds. Though a combination of ab-initio cluster many-body c...

BACKGROUND Cytochrome P4502E1 (CYP2E1) has been suggested to play critical roles in the pathogenesis of alcoholic fatty liver (AFL), but the underlying mechanisms remains unclear. The current study was designed to evaluate whether CYP2E1 suppression by chlormethiazole (CMZ) could suppress AFL in mice, and to explore the underlying mechanisms. METHODS Mice were treated with or without CMZ (50 ...

AIM Paracrine interaction between macrophages and adipocytes in obese visceral fat tissues is thought to be a trigger of chronic inflammation. The immunomodulatory effect of the short chain fatty acid, butyric acid, has been demonstrated. We hypothesize that sodium butyrate (butyrate) attenuates inflammatory responses and lipolysis generated by the interaction of macrophages and adipocytes. M...
