Open-pit coal mining causes land and soil degradation negatively affects properties. It is of great importance to determine variabilities in properties the abandoned area after mine closed bring it back nature by implementing appropriate rehabilitation programs. The aim this study was evaluate plant nutrient availability toxic element pollution an site. results indicated that amounts plant-avai...

Using selective cytochrome P450 (CYP) inhibitors and clinical concentrations (4 microM) of dapsone (DDS), we found a major contribution of CYP2C9 and little or no contribution (< or = 10%) of CYP3A4 and CYP2E1 to dapsone N-hydroxylation (DDS-NHY) in human liver microsomes. Sulfaphenazole (2.16 microM) and tolbutamide (500 microM), selective inhibitors of CYP2C9 (or 2C8/9), inhibited DDS-NHY by ...

The aim of this study was to determine human prenatal and postnatal exposures to polybrominated diphenyl ethers (PBDEs), polychlorinated biphenyls (PCBs), hydroxylated metabolites of PCBs (polychlorobiphenylols; OH-PCBs), and pentachlorophenol (PCP). The median PBDE fresh-weight concentrations in maternal and cord blood plasma and in breast milk were 24, 4.3, and 75 pg/g, respectively. The PCB ...

There is a growing concern regarding the recurrent observation of aflatoxins (AFs) in the milk of lactating animals. Regarding this, the present study was conducted to assess the aflatoxin M1 (AFM1)-binding ability of three species, namely Lactobacillus rhamnosus, L. plantarum, and Saccharomyces boulardii, inAFM1-contaminatedmilk. The mentioned species were a...

this study was performed during the abatement of two asbestos-containing materials (acm):baumlite board (cement flat board) and ceiling textile. the concentrations of total dust for personal sampling were 0.28 and 1.70 mg/m3 during baumlite board and ceiling textile abatements, respectively, when calculated with 8-hr time-weighted average (twa). the geometric mean (gm) asbestos concentrations w...

The pharmacokinetics of cephradine suspension were studied in 16 infants and children who were 13 months to 8 years and 3 months of age (means age, 3.5 years). Mean peak concentrations of 21.3 and 9.9 ,tg/ml were achieved at 30 min after administration of 60-mg/kg doses to fasting and nonfasting patients. The area under the serum concentration-time curve was 26% larger in fasting than in fed su...

In aquaculture, activities with anesthetic compounds are usually used in order to ensure the welfare of farmed fish, allowing handling out of water with decreased trauma by stress. Presently, there is no information about anesthetic action of eugenol in early life stages of Nile tilapia (Oreochromis niloticus). The objective of this study was to evaluate different concentrations of eugenol for ...
