Plant cells have been reported to play an important role in the uptake of organic contaminants. This study was undertaken to provide an insight into the role of the root cell walls and their subfractions on sorption of phenanthrene to roots of wheat (Triticum aestivum L.). Root cell walls were isolated and further sequentially fractioned by removing pectin, hemicellulose one, and hemicellulose ...

We here describe the structural requirements for Golgi localization and a sequential, localization-dependent activation process of protein kinase C (PKC) mu involving auto- and transphosphorylation. The structural basis for Golgi compartment localization was analyzed by confocal microscopy of HeLa cells expressing various PKC mu-green fluorescent protein fusion proteins costained with the Golgi...

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...

thechah nimeh reservoirs of sistan is as one of the main water sources of zabol city used for drinking, agriculture, industry and livestock purposes. this study aimed to determine the contribution of the natural and concentration factors of heavy metals such as cd, pb and cu in sediment of chah nimeh of sistan. the concentrations of heavy metals in surface sediments were studied in six stations...

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...

Introduction: Curcuma zedoaria Roscoe (C. zedoaria) is used in traditional medicine for various diseases, including inflammation. This study aimed to evaluate the vitro anti-inflammatory activity of aqueous extract C. rhizome and its fractions develop an cream incorporating extract. Methods: The crude was prepared by decoction method. A portion it freeze-dried other part subjected sequential fr...

Soil arsenic (As) fractionation and its bioaccessibility are two important factors in human health risk assessment. However, data related to the impact of As minerals on with gut microbiota involvement scarce. In this study, speciation analysis was determined using HPLC-ICP-MS XANES after incubation colon from origin, combination sequential extraction. Significant increase contributed primarily...

Abstract The aim of this study was to determine the distribution alpha-emitting plutonium isotopes from arable and uncultivated soils. effect soils cultivation on fractionation mobility studied using sequential extraction technique (modified Tessier’s method). Soil samples were collected surface layer in selected points. By means reagents with increasing leaching power, fractions separated: rea...

This study aims at evaluating the effect of different wastewater composition on kinetics, capacities, and mechanisms P sorption by carbonated bauxite residues (CBR). A series batch experiments was performed to investigate behaviors from solutions prepared with aqueous matrices (deionized water, tap real wastewater) initial concentrations (from 10 200 mg P/L). Also, a sequential extractions frac...
