1-Chloro-1-fluoroethene (1,1-CFE) was studied as a reactive tracer to quantify the anaerobic transformation of vinyl chloride (VC). Batch kinetic studies of 1,1-CFE and VC transformation were performed with an enrichment culture obtained from the Evanite site in Corvallis, OR. The culture is capable of completely transforming trichloroethene (TCE) through cis-dichloroethene (c-DCE) and VC to et...

background: extraction of blood genomicdnais one of the main approaches for clinical and molecular biology studies. although several methods have been developed for extraction of blood genomic dna, most of these methods consume long time and use expensive chemicals such as proteinase k and toxic organic solvent such as phenol and chloroform. the objective of this study was to developed easy and...

Although the water-soluble metabolite profile of human mesenchymal stem cells is known, the lipid profile still needs further investigation. In this study, methanol-chloroform was used to extract pid-soluble metabolites and perchloric acid was used to extract water-soluble metabolites. Furthermore, a dual phase extraction method using methanol-chloroform and water was used to obtain both water ...

The common bean is an important source of iron and zinc in humans. Increases in the contents of these minerals can combat mineral deficiencies, but these contents are influenced by environmental conditions. Thus, the objectives of this study were to investigate the interaction between common bean lines and water availability on iron and zinc contents (CFe and CZn, respectively), identify superi...

Stem-cell-based therapies are regarded as promising treatments for neurological disorders, and adipose-derived stem cells (ASCs) are a feasible source of clinical application of stem cell. Recent studies have shown that stem cells have a therapeutic potential for use in the treatment of various illnesses through paracrine action. To examine the effects of cell components of ASCs on neural stem ...

BACKGROUND Sequentially mapped complex fractionated atrial electrograms (CFAE) and dominant frequency (DF) sites have been targeted during catheter ablation for atrial fibrillation (AF). However, these strategies have yielded variable success and have not been shown to correlate consistently with AF dynamics. Here, we evaluated whether the spatiotemporal stability of CFAE and DF may be a better...

AIM The aim of this survey was to compare four DNA extraction methods from Iranian sheep strain E.granulosus isolates. BACKGROUND Cystic echinococcosis (CE) caused by the metacestode of the dog tapeworm Echinococcus spp., is a global zoonotic infection which is economically important and constitutes a major threat to public health in many countries. Strains characterization is essential for t...

Coleus forskohlii extract (CFE), an herbal ingredient, is used for weight-loss products. CFE's alleged efficacy is attributed to forskolin. However, CFE has been shown to induce fatty liver in mice, with components other than forskolin playing a part in this effect. The present study addressed the underlying mechanism of CFE-induced fatty liver by analyzing changes in CFE-treated mice of lipid ...

The cloning efficiency (CFE-F) of stromal precursor cells (CFU-F) in cultures of heterotopic transplant cells and the quantity of CFU-F in bone marrow transplants from old donors to old recipients (O-O group) has decreased almost eight times, compared with transplants where the bone marrow from young donors has been transplanted to young recipients (Y-Y group). However, in the O-Y group, the CF...
