A novel hydrophilic polyurethane (abbreviated as W-OH) was developed and applied as a sustainable sand-fixing material. This paper on the chemical sand fixation mechanism of W-OH discusses the adhesive force between the W-OH solid and sand particles. The solidification mechanism was investigated and the solidifying time was tested. And then the thickness and porosity of the W-OH sand-fixing lay...

Sgs1, the budding yeast homolog of the mammalian BLM helicase, has been implicated in preventing excess recombination during both vegetative growth and meiosis. Most meiotic crossover (CO) recombination requires full function of a set of yeast proteins (Zip1, Zip2, Zip3, Zip4/Spo22, Mer3, Msh4, and Msh5, termed the SIC or ZMM proteins) that are also required for homologous chromosome synapsis. ...

Two isomorphous 3D Mn(II) and Co(II) coordination polymers with a dicarboxylate inner salt and cyanate as coligands were synthesized and structurally characterized, and their magnetic properties have been studied. In the compounds, [M(L)(NCO)](n).nH(2)O (M = Mn, Co, L = 1-carboxymethylpyridinium-4-carboxylate), neighboring metal ions are linked by the 3-fold bridges of an end-on cyanate and two...

PURPOSE. Retinal nerve fiber layer (RNFL) thickness measured by optical coherence tomography (OCT) can be unreliable in the presence of a myopic tilted disc. The purpose of this study was to investigate the influence of the calculation circle location of spectral domain (SD)-OCT when measuring RNFL thickness in healthy subjects with myopic tilted disc. METHODS. Sixty-nine eyes with myopic tilte...

The hexanuclear phosphido-bridged dication [Pt6(μ-PBu(t)2)4(CO)6](2+), (1)(2+), reacts under mild conditions with pseudo-halide anions (CN(-), NCO(-), NCS(-)) to afford the corresponding neutral bis-substituted clusters Pt6(μ-PBu(t)2)4(CO)4X2 (2, X = CN; 3, X = SCN; 4, X = NCO). The reaction with sodium azide affords 4, which may arise from the formation of the intermediate bis-azido derivative...

Accurate thermochemical data of small molecules are invaluable to the progress of every aspect of chemistry, especially in the atmosphere, combustion and industry. In this work, photofragmentation translational spectroscopy and 1st principles electronic structure theory reveal the literature value of the heat of formation of chlorine-isocyanate to be in error by more than 40 kcalmol. We report ...

Background. In the pathogenesis of complications diabetes mellitus (DM), in addition to glucotoxicity, development oxidative stress plays a leading role. Antioxidants have been great interest for physicians recent years. Contemporary diabetology focused on search and practical implementation pathogenetic medications that can affect main chains DM prevent its negative consequences. Purpose study...
