1. N-Phenylmaleimide irreversibly inhibits pyruvate transport into rat heart and liver mitochondria to a much greater extent than does N-ethylmaleimide, iodoacetate or bromopyruvate. alpha-Cyanocinnamate protects the pyruvate transporter from attack by this thiol-blocking reagent. 2. In both heart and liver mitochondria alpha-cyanocinnamate diminishes labelling by [3H]N-phenylmaleimide of a mem...

Silver (Ag) nanoparticles were successfully prepared by using the in-liquid pulsed plasma technique. This method is based on a low voltage, spark discharge in dielectric liquid. We explore effect of protecting ligands, specifically Cetyl Trimethylammonium Bromide (CTAB), Polyvinylpyrrolidone (PVP), and Sodium n-Dodecyl Sulphate (SDS), used as surfactant materials to prevent nanoparticle aggrega...

The study carried out to evaluate some of the physical and chemical properties ground water samples from west Alshirqat district, Salaheddin province, IRAQ. Six wells selected, sample collected every month for 6 months (October,2021 – March 2022). In each electric conductivity (EC), pH, total dissolved solid (TDS), oxygen (DO), biological demand (BOD), hardness (TH), calcium (Ca H), magnesium (...

Two major proteins have been identified in sodium citrate extracts of bovine pancreatic stones from 15 glands with lithiasis. They were found to have a molecular weight of about 24 000 and were further characterized by a variety of methods, including polyacrylamide-gel electrophoresis in the presence of sodium dodecyl sulphate, isoelectric focusing, two-dimensional electrophoresis, immunodiffus...

In the heavy fraction of deoxycholate-treated spinach chloroplasts the chlorophyll aII activity is high and the chlorophyll aI activity is low when no artificial electron donor is added. The addition of the photosystem I donor system N-methyl-phenazonium sulphate plus sodium ascorbate (PMS + Asc) leads to a complete reactivation of the chlorophyll aI reaction. The addition of the photosystem II...

this research aimed to study on effect of foliar spraying with zinc (as zinc sulphate), nitrogen (as urea) and iron (as sulphate and chelated fe) on growth parameters, quality of fruit, flower characteristics, chemical constituents and nutrients content of leaves on grapevine. applied nutrients were zinc sulphate (zn) of 0.0 and 1.5gl-1 and urea (n) at 0.0 and 5 gl-1 and fe (1) control (low fe)...
