Among African immigrants in Melbourne, Victoria, Australia, we demonstrated lower geometric mean vitamin D levels in immigrants with latent tuberculosis infection than in those with no Mycobacterium tuberculosis infection (P=.007); such levels were also lower in immigrants with tuberculosis or past tuberculosis than in those with latent tuberculosis infection (P=.001). Higher vitamin D levels w...

Objective: To investigate the effects of the methylene chloride:methanol (CH 2 Cl 2 :MeOH, Animal Physiology and 1:1) extract of the dried roots of Mondia whitei Linn and its hexane and methanol fractions on Phytopharmacology potassium chloride (KCl) and adrenaline (Adr)-induced contractions of rat vas deferens. Laboratory, Faculty of Science, Materials and Methods: Isolated strips of normal ad...

Concentrated CaCl2 and CaBr2 salt solutions of densities up to 2.3 kg L-1 are regularly used to control hydrostatic pressure in oil wells during special operations in the exploration and production of natural gas and crude oil. Various concentrations of high density salts are frequently left in mud pits near the drilling site as waste, polluting fresh and ground waters by spillage and drainage....

onion (allium cepa) bulb from liliaceae has antioxidant, spasmolytic and antihypertensive activities. the aim of present study was to investigate the antispasmodic effect of onion peel on rat ileum contractility. onion peel powder was extracted by maceration in 70% alcohol for 72 h. a terminal portion of ileum from male wistar rat was dissected and its contractions were recorded isotonically in...

Using response surface methodology (RSM), this study investigates the effect of NaCl substitution (50%) with KCl, CaCl2, and MgCl2 in packaging brines (controlled variables) on characteristics (responses) plain green Spanish-style Manzanilla olives, maintaining salt-mixture level 5%. The RSM showed that increment CaCl2 caused a linear significant (p-value ≤ 0.05) decrease pH increase firmness (...

PURPOSE Estrogens and androgens are elevated in obesity and associated with increased postmenopausal breast cancer risk, but the effect of weight loss on these biomarkers is unknown. We evaluated the individual and combined effects of a reduced-calorie weight loss diet and exercise on serum sex hormones in overweight and obese postmenopausal women. PATIENTS AND METHODS We conducted a single-b...

An existing idle cooling tower can be reversibly used as a heat-source tower (HST) to drive a heat pump (HP) in cold seasons, with calcium chloride (CaCl2) aqueous solution commonly selected as the secondary working fluid in an indirect system due to its good thermo-physical properties. This study analyzed the effect of CaCl2 mass fraction on the effectiveness (ε) of a closed HST and the coeffi...

The cement industry is carbon-intensive, and the valorisation of industrial side-streams/residuals for use as alternative raw materials can enable to reduce its carbon footprint well promote resource efficiency. Apart from key clinker ingredients such CaO, Al2O3, SiO2, residues also contain MgO, CaCl2, SO3. Therefore, this study investigates formation assemblages in system CaO-SiO2-Al2O3-SO3-Ca...
