Hydrogen sulfide (H2S) has been revealed to be a signal molecule with second messenger action in the somatic cells of many tissues, including the reproductive tract. The aim of this study was to address how exogenous H2S acts on the meiotic maturation of porcine oocytes, including key maturation factors such as MPF and MAPK, and cumulus expansion intensity of cumulus-oocyte complexes. We observ...

Abstract—We investigated ecotoxicity and performed experiment for removing ZnO nanoparticles in water. Short term exposure of hatching test using fertilized eggs (O. latipes) showed deformity in 5ppm of ZnO nanoparticles solution. And in 10ppm ZnO nanoparticles solution delayed hatching was observed. Hereine, chemical precipitation method was suggested for removing ZnO nanoparticles in water. T...

Zinc sulphide nanoparticles (ZnS NPs) were successfully synthesized by chemical co-precipitation method at 20°C and 40°C using zinc chloride (ZnCl2 ) sodium (Na2S) as precursors. Ascorbic acid was used a capping agent. The ZnS NPs characterized X-ray diffraction (XRD), UV-visible Fourier transform infrared (FTIR) spectroscopy. spectra showed that the bandgap of 3.8-3.9 eV two different temperat...

Holo and apo adrenodoxin were studied by differential scanning calorimetry, absorption spectroscopy, limited proteolysis, and size-exclusion chromatography. To determine the conformational stability of adrenodoxin, a method was found that prevents the irreversible destruction of the iron-sulfur center. The approach makes use of a buffer solution that contains sodium sulfide and mercaptoethanol....

The separation of nanoparticles from a solution-based photocatalytic reaction is significant problem in practical applications. To address the issue, we developed new photocatalyst composite based on ZnO-ZnS heterojunction (ZnOS) embedded polyvinyl alcohol (PVA) hydrogel, which showed satisfactory results for recycling. PVA-ZnOS hydrogel was fabricated by freezing-induced gelation, enabled enca...

CuGaS2, (AgInS2)x-(ZnS)2-2x, Ag2ZnGeS4, Ni- or Pb-doped ZnS, (ZnS)0.9-(CuCl)0.1, and ZnGa0.5In1.5S4 showed activities for CO2 reduction to form CO and/or HCOOH in an aqueous solution containing K2SO3 and Na2S as electron donors under visible light irradiation. Among them, CuGaS2 and Ni-doped ZnS photocatalysts showed relatively high activities for CO and HCOOH formation, respectively. CuGaS2 wa...

We report a scanning photocurrent microscopy (SPCM) study of colloidal lead selenide (PbSe) quantum dot (QD) thin film field-effect transistors (FETs). PbSe QDs are chemically treated with sodium sulfide (Na2S) and coated with amorphous alumina (a-Al2O3) by atomic layer deposition (ALD) to obtain high mobility, air-stable FETs with a strongly gate-dependent conductivity. SPCM reveals a long pho...
