Urban ares are subjected to intensive pollution due continuous anthropogenic activity. In order assess the influence of thermal power plants and waste incineration on City Moscow recreational areas, mass fractions 37 major trace elements were determined using instrumental neutron activation analysis in soil samples collected at two different depths vicinity more potential contamination sources....

The ratio of cosmogenic 10 Be and its stable isotope 9 has been used as a proxy long-term continental weathering fluxes denudation rates, but transport processes these isotopes from river water to estuarine seawater, well interference potential anthropogenic source on natural Be/ around populated estuaries are not constrained. Here, we present results concentrations dissolved reactive particula...

Factor requirements for yeast and rat liver ribosomes were determined in several different reactions using either yeast or liver factors. In polymerization assays yeast ribosomes required a factor in addition to elongation factor 1 (EF-1) and elongation factor 2 (EP-2). The third factor (EF-3) requirement was observed with EFs from either yeast or liver for both poly(U)-directed polyphenylalani...

Concentrations of heavy metals (As, Co, Cu, Ni, Mo, Pb and Zn) are studied in the soil of Shiraz industrial complex zone, south Shiraz, Iran to asses metal contamination due to industrialization, urbanization and agricultural activity. Soil samples were collected from three different depths. The A and C depths are enriched with metals such as Ni, As, Mo, Cu, Pb and Zn, compared with the B depth...

Environmental enrichment (EE) is a widely used paradigm for investigating the influence of complex stimulations on brain and behavior. Here we examined whether pre-reproductive exposure to EE of female rats may influence their maternal care and offspring cognitive performances. To this aim, from weaning to breeding age enriched females (EF) were reared in enriched environments. Females reared i...

The antagonist-bound crystal structure of the nociceptin receptor (NOP), from the opioid receptor family, was recently reported along with those of the other opioid receptors bound to opioid antagonists. We recently reported the first homology model of the 'active-state' of the NOP receptor, which when docked with 'agonist' ligands showed differences in the TM helices and residues, consistent w...

The total concentrations and chemical forms of heavy metals (Cd, Cr, Cu, Ni, Pb and Zn) in the surface sediments of the Laizhou Bay and the surrounding marine area of the Zhangzi Island (hereafter referred to as Zhangzi Island for short) were obtained and multiple indices and guidelines were applied to assess their contamination and ecological risks. The sedimentary conditions were fine in both...

In polymerization assays yeast ribosomes required a factor in addition to elongation factor 1 (EF-1) and elongation factor 2 (EF-2).

Abstract The ecological risk resulting from the accumulation of some heavy metals in sediments Iskenderun Bay was assessed using following measures: enrichment and contamination factor, pollution load index ( PLI ), potential RI ). concentrations studied were order: Fe > Ni Mn Cr Zn Cu As Pb Cd Hg. had highest EF values. This situation is most likely due to presence iron, pesticide, fertiliz...

While airborne particulate matter (PM) pollution is a serious problem for urban environments, it can be reduced through uptake by plant leaves. In this study, we investigated and compared the of PM-bound toxic metals different species. Enrichment factor (EF) correlation analyses across sample types indicated anthropogenic origins these with source signatures. Scanning electron microscopy (SEM) ...
