“The Sr-induced reconstructions on Si(100) at elevated temperature were studied using scanning Ferroptosis inhibitor tunneling microscopy and reflection high energy electron diffraction. With the Sr coverage increasing from 0 to 0.5 monolayer, the surface exhibits phase transitions from 2 x 1-Sr to 2 x 3-Sr and then to 1 x 2-Sr. The bias-dependent, high resolution STM images unambiguously support a dimer-vacancy structural model

for the 2 x 3-Sr phase. Furthermore, the coverage-dependent evolution of the surface from 2 x 3-Sr to 1 x 2-Sr can also be nicely explained by extending the 2 x 3-Sr model to the 1 x 2-Sr. (C) 2011 American Institute of Physics. [doi:10.1063/1.3554829]“
“Nitric oxide (NO) is a well known potent antiplatelet agent, and its continuous release will effectively prevent the adhesion of platelets on artificial blood vessel walls. In this paper, polycarbonateurethane (PCU) with lipophilic Cu(II)-complex (Cu(II)-DTTCT) blending films were prepared and used as catalyst to generate NO from nitrite. The mechanical properties of PCU films blended with Cu(II)-DTTCT were characterized by tensile strength measurement. The tensile stress and Young’s modulus of PCU films

blending with Cu(II)-DTTCT increased, however, the elongation at break decreased compared with corresponding PCU films. The NO generation was investigated in vitro in the presence of NaNO(2) and ascorbic acid in PBS (pH = 7.4) at 37 degrees C. The 8-Bromo-cAMP manufacturer flux of NO generation was quantitatively measured by Griess assay. NO flux and velocity increased with the increase of NaNO(2) concentration, the concentration

of ascorbic acid in PBS and the amount of Cu(II) in the films. The loss of Cu(II) from blending film surfaces was found during the in vitro NO generation experiments, which resulted in the decrease of NO flux in the second run. The PCU film could catalyze continually generation of NO for two days, which will provide a promising Q-VD-Oph in vivo approach that enable endogenous NO generation on the surface of the medical devices. The generation of biologically active level of NO at the blood/polymer interface can reduce the risk of thrombosis on the implants. Polycarbonateurethane films with NO generation function may be used as high thromboresistant blood contacting materials or coating. (C) 2011 Wiley Periodicals, Inc.

“This study compared tankyrase 1 expression and autophagy quantity between erectile dysfunction (ED) and non-ED rats’ corpus cavernosum smooth muscle cells (CSMCs). This study aslo explored the effect and possible mechanism of tankyrase 1 on autophagy and cell proliferation in ageing ED rats’ CSMCs.
