Kinetic parameters (Km and kcat.) of the two major forms (A and B) and a minor form (C) of human liver N-acetylglucosamine-6-sulphate sulphatase [Freeman, Clements & Hopwood (1987) Biochem. J. 246, 347-354] were determined with a variety of substrates matching structural aspects of the physiological substrates in vivo, namely heparin, heparan sulphate and keratan sulphate. Enzyme activity is hi...

Methanogens and sulphate reducing bacteria compete for H2 in the human colon, and, as a result, faeces usually contain high concentrations of just one of these two organisms. There is controversy over which of these organisms wins the competition for H2, although theoretical data suggest that sulphate reducing bacteria should predominate. To elucidate this question experiments were undertaken i...

conclusions the addition of 50 mg of magnesium sulfate to a bupivacaine–fentanyl solution for intrathecal anesthesia improved the efficacy and duration of the analgesia without any significant side effects. the addition of 150 µg of neostigmine increased the incidence of hypotension, bradycardia, and nausea and vomiting. moreover, neostigmine failed to prolong analgesia duration. results group ...

Methyl orange dye-doped K2SO4 single crystal has been synthesized by a slow evaporation method, and its properties have investigated. The powder X-ray diffraction (PXRD) studies on the confirmed crystalline property, noncentrosymmetric system, space group P63/mmc (D64th) of crystal. reaction involved in functional grown from FTIR analysis. optical absorbance band gap were calculated UV-Vis obta...

This study aimed to assess and compare the quality of groundwater in city Al-Marj Libya with international standard guidelines for drinking water recommended by World Health Organisation. An evaluation wells area was conducted. Standard techniques, such as Minitab (v. 16) ArcGIS (v.10.2), were used analytics physicochemical biological parameters samples. assessment calculation conducted on basi...

The color of dye aqueous solution which cannot be removed by coagulation was selected to decolourize it through adsorption process using novel adsorbents namely Flocs Ferric Sulphate, Aluminium sulphate and Manganese sulphate. In order know efficacy adsorbents, batch sorption studies equilibrium were conducted. Good removal achieved with at pH::4 Sulphate pH::10, will applicable reduce the indu...

Hydrogen produced during colonic fermentation may be excreted, or removed by H2 consuming bacteria such as methanogenic and sulphate reducing bacteria. In vitro, sulphate reducing bacteria compete with methanogenic bacteria for hydrogen when sulphate is present. In this study the hypothesis that sulphate in the diet could alter CH4 production in vivo has been tested. Six methane excreting volun...
