A high throughput process including subcellular fractionation and multiple protein separation and identification technology allowed us to establish the protein expression profile of human fetal liver, which was composed of at least 2,495 distinct proteins and 568 non-isoform groups identified from 64,960 peptides and 24,454 distinct peptides. In addition to the basic protein identification ment...
Field-flow fractionation (FFF) is an analytical technique particularly suitable for the separation, isolation, and characterization of macromolecules and micrometer- or submicrometer-sized particles. This chromatographic-like methodology can modulate the retention of micron-sized species according to an elution mode described to date as "steric hyperlayer". In such a model, differences in sampl...
Stable isotope analysis is recognized as a powerful tool for monitoring, assessing, and validating in-situ bioremediation processes. In this study, kinetic carbon isotope fractionation factors (epsilon) associated with the aerobic biodegradation of vinyl chloride (VC), cis-1,2-dichloroethylene (cDCE), and trichloroethylene (TCE) were examined. Of the three solvents, the largest fractionation ef...
Fractionation of cells into their subcellular components has long been a central approach in cell biology. Subcellular fractionation techniques have been used widely to study structure and function of organelles and subcellular compartments, as well as to examine the location, processing, and trafficking of molecular components. The object of most subcellular fractionation procedures is to obta...
BACKGROUND & OBJECTIVE Radiotherapy is an important treatment for nasopharyngeal carcinoma (NPC). Timing of radiotherapy has attracted more attention nowadays. This study was to assess the efficacy of accelerated fractionation (six fractions per week) versus conventional fractionation (five fractions per week) for NPC, thus to improve treatment efficacy without increasing complications. METHO...
background: the exposure of cell lines to low-dose irradiation leads to changes at molecular level, which may induce adaptive response. we examined radio-adaptive doses effect on human colorectal adenocarcinoma cell line (ht29) and human fetal fibroblasts (mrc5) cell line followed by hyper and hypo fractionation regimes, with main purpose to decrease cell viability in ht29, and at the same time...
