Biological uranium reduction was investigated using bacteria isolated from a uranium mine in Limpopo, South Africa. Background uranium concentration in soil from the mine was determined to be 168 mgkg(-1) much higher than the typical background uranium concentration in natural soils (0.30-11.7 mgkg(-1)). Therefore it was expected that the bacteria isolated from the site were resistant to U(VI) ...

Pregnancy increases the urinary excretion of chemicals in women and rodents. It is unknown whether the enhanced clearance of drugs during pregnancy involves changes in the expression of transporters that mediate chemical secretion and reabsorption. The purpose of this study was to quantify the mRNA and protein expression of efflux transporters in kidneys from virgin and pregnant mice on gestati...

Focus Mar. 2003 Volume 25.1 3 incorporation into product during PCR. The design is based on the effects of the primary and secondary structure of oligonucleotides on the emission properties of attached fluorescent dyes (6). The design factors are used in a proprietary primer design software, called LUXTM Designer, that is used to design and order fluorogenic LUXTM Primers and unlabeled counterp...

Carbon Spheres were fabricated by hydrothermal method and their structural properties were investigated. Carbon Spheres with average sizes around of 230, 320 and 430 nm were synthesized in different concentration of glucose aqueous solution and different hydrothermal reaction time. The temperature of 180 °C by a hydrothermal reaction was fixed in all of glucose concentration and hydrothermal re...
