Bacillus cereus was used to remove Cr(VI) in tannery wastewater containing medium at different initial Cr(VI) concentration, temperature, pH and biomass to get better conditions. At the optimum condition, the Cr(VI) in tannery wastewater was treated by each component of the cells to detect the capacity of the components for the Cr(VI) reduction. Also, the Bacillus cereus was continuous cultured...

The present study describes management of oxidative stress induced by heavy metal chromium in marine Bacillus licheniformis (NCBI GenBank Accession NumberHM194725). It is identified that the isolate reduces 10-1500 mg/L of Cr (VI) within 24-72 h. Existence of chromium reductase in growth medium implies the possibility of enzymatic reduction of Cr (VI) to Cr (III). Nevertheless, no correlation w...

Magnetic resonance spectroscopy (MRS) noninvasively provides information on the concentration of some cerebral metabolites in vivo. Among those measurable by proton magnetic resonance spectroscopy (1H-MRS), N-acetyl-aspartate (NAA) is decreased, and myo-inositol (ml) and choline (Cho) levels are increased in patients with Alzheimer's disease (AD). Donepezil, an acetylcholinesteraze inhibitor, h...

Indinavir plasma levels are associated with antiretroviral efficacy; however, little data are available regarding toxicity. We assessed the relationship between indinavir pharmacokinetic (PK) characteristics and severe nephrolithiasis as well as other severe or serious adverse reactions. Patients included in the ANRS CO8 APROCO-COPILOTE cohort and receiving 800 mg indinavir three times daily as...

Crossbred steers (n = 180; 230 ± 6 kg) were fed during a 56-d receiving period to determine if supplementing chromium (Cr; KemTRACE Chromium Propionate 0.04%, Kemin Industries) would improve feedlot performance and health of newly-received cattle. A completely randomized block design (36 pens; 9 pens/treatment; 5 steers/pen) was used. Chromium premixes were supplemented to add 0 (Con), 0.1, 0.2...

The bacterium MNU16 was isolated from contaminated soils of coal mine and subsequently screened for different plant growth promoting (PGP) activities. The isolate was further identified by 16S rRNA sequencing as Bacillus subtilis MNU16 with IAA concentration (56.95 ± 0.43 6μg/ml), siderophore unit (9.73 ± 2.05%), phosphate solubilization (285.13 ± 1.05 μg/ml) and ACC deaminase activity (116.79 ...

Conditions for the determination of the fasting urinary hydroxyproline: creatinine ratio (OHPr: Cr ratio) have been examined, using a resin-catalysed hydrolysis and automated colorimetric procedure for the determination of hydroxyproline. Feeding experiments with gelatin showed that hydroxyproline is rapidly absorbed and excreted in the urine and that a 12-hour (overnight) fast is sufficient to...

The article depicts the geochemical properties of landscapes in Ada Tepe gold mine area before its launching. research is conducted by examining heavy metals (Cu, Pb, Zn, Co, Cr, Mn and Ni) content samples river sediments local landscapes. aims to analyse concentration launch mining. study implements coefficient Clarke concentration. deviation from background concentrations a ratio between elem...

A new method involving pre-concentration on modified silica fiber is described for the speciation of chromium(III) [Cr(III)] and chromium(VI) [Cr(VI)] in aqueous media. This method is based on the different chelating behavior of Cr(III) and Cr(VI) with morpholine-4-carbodithioate (MDTC). Both complexes are extracted on silica fiber modified by sol-gel technology by using 3-aminopropyltriethoxys...

background: radon concentration was measured in the soil and indoor of amman and al- rusaifa cities in jordan during summer season. materials and methods: the measurement was performed using time-integrated passive radon dosimeters, containing a solid state nuclear track plastic detector, commercially known as cr-39. results: radon concentration levels in the soil ranged from 2.8 ± 1.2 to 6.9 ±...
