background serum apoptotic cytokeratine 18 neoepitope m30 (ck-18 m30) and matrix metalloproteinase 2 (mmp-2) have been popular markers for detecting liver fibrosis in recent years. ck-18 is a major intermediate filament protein in liver cells and one of the most prominent substrates of caspases during hepatocyte apoptosis. mmp-2 plays an important role in tissue remodeling and repairing process...

results genotype frequencies of g/a in fertile and infertile men were significantly different (χ2 = 4.16, df = 1, p = 0.041). genotype frequencies of g/g and a/ain fertile and infertile men were not significantly different (χ2 = 3.32, df = 1, p = 0.068 and χ2 = 0.521, df = 1, p = 0.47, respectively). the risk of infertility was 1.43 folds higher in individuals with the a/a genotype compared to ...

While editing this week’s cover story on the electrolyzers needed for clean hydrogen production, I couldn’t help wondering if producing H 2 really makes sense a national scale (page 24). The idea is to run low-carbon electricity through that split water into and oxygen. can then be stored used as fuel or raw material in place of oil natural gas. It’s nice idea, one already being carried out lim...

Non-hydrogenative Para-Hydrogen Induced Hyperpolarization (nhPHIP) is a Nuclear Magnetic Resonance (NMR) hyperpolarization technique which has experimentally been used to analyze complex biological samples containing amino acids using the Ir-IMes transfer catalyst. A computational study based on Density Function Theory (DFT) was performed all relevant stereoisomers of [Ir(H)2(IMes)(AA)(Py)] (wi...

objective: diabetes plays an important role in the progression of tissue damage. influencing factors of the cellular matrix can lead to changes in the structure and function of tissues or their failure. herbal consumption can be effective in reducing tissue failure. the aim of the this study is to research the effect portulaca oleracea seeds on the levels of matrix metalloproteinase 2, 9 and ti...

The stereochemical course of the amidopalladation of alkenes has important implications for the development of enantioselective Pd-catalyzed "Wacker-type" oxidative amidation of alkenes. We have recently shown that the addition of base (Na2CO3) can alter the stereochemical course of amidopalladation in the (IMes)Pd(TFA)2(H2O)-catalyzed aerobic oxidative amidation of alkene. In this study, the m...
