We perform a model-independent analysis of solar neutrino flux rates including the recent charged-current measurement at the Sudbury Neutrino Observatory (SNO). We derive a universal sum rule involving SNO and SuperKamiokande rates, and show that the SNO neutral-current measurement cannot fix the fraction of solar nu(e) oscillating to sterile neutrinos. The large uncertainty in the standard sol...

BACKGROUND Although overexpression of nitric oxide synthases (NOSs) has been found associated with prostate diseases, the underlying mechanisms for NOS-related prostatic diseases remain unclear. One proposed mechanism is related to the S-nitrosylation of key regulatory proteins in cell-signaling pathways due to elevated levels of NO in the prostate. Thus, our primary objective was to identify S...

Evidence suggests that S-nitrosylation is a biological process involved in cerebral ischemia. The aim of the present study was to elucidate the effects of S-nitrosylated (SNO) polyethylene glycol-conjugated (PEG) hemoglobin (Hb) developed as an artificial oxygen carrier, which can absorb free NO and translocate NO to a sulfhydryl (SH) moiety, on ischemic cerebral dysfunction. Long-term potentia...

SnO(2) nanowires with lengths in the tens of micrometres range have been synthesized on a large scale via a facile polyethylene glycol-directed method at ambient temperature followed by a suitable thermal treatment of the precursor nanowires. The morphology of the precursor of the SnO(2) nanowires is tunable by changing the concentration of either SnCl(2) or polyethylene glycol. After calcinati...

Porous SnO(2) nanospheres with high surface areas have been synthesized through a solvothermal method in the absence of any templates. The structure and morphology of the resultant products were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS) and nitrogen adsorption-desorption technique....

This paper describes the morphology, stoichiometry, microstructure and gas sensing properties of nano clustered SnOx thin films prepared by Sn evaporation followed by the Rheotaxial Growth and Thermal Oxidation (RGTO) process. Electron microscopy was used to investigate, in detail, the evolution of the films as the oxidation temperature was increased. The results showed that the contact angle, ...

Accumulating evidence indicates that S-nitrosylation plays an important role in protein function either physiologically or pathologically. In the present study, we describe a modified method for the isolation and enrichment of S-nitrosylated (SNO) proteins from brain tissue based on a biotin labeling system using the biotin switch technique (BST). Various working conditions for the incubation o...
