this study was conducted to assess the concentration of some heavy metals and to examine their contamination hazard in atmospheric dust of urban, industrial and non-urban areas in bushehr province, southwestern iran. fifty dust samples from the leaves of the palm trees and fifty surface soil samples from bushehr and assaluyeh cities as urban and industrial areas, respectively, and also from the...

The Subarnarekha River is one of the most important east flowing rivers of India. The river in West Bengal and Odisha is site for the Subarnarekha Barrage Project and Kirtania port respectively. The major objectives of the present study were to investigate the pre-projects level of heavy metals in water and sediments of the Subarnarekha River along the projects’ sites. Water and Surface sedimen...

pollution of water and soils by heavy metals is an emerging problem in industrialized countries.the present study was conducted to investigate the heavy metals concentration in water and sedimentsamples from ship breaking sites of sitakunda to assess the potential ecological risk posed by heavy metalusing different methods. heavy metals concentration was analyzed by atomic absorption spectrosco...

This research intends to offer a scientific foundation for environmental monitoring and early warning which will aid in the protection management of Qaroun Lake. Lake is increasingly influenced by untreated wastewater discharge from many anthropogenic activities, making it vulnerable pollution. For that, six pollution indices, namely contamination factor (Cf), enrichment (EF), geo-accumulation ...

PURPOSE The epidermal growth factor receptor (EGFR) autocrine signaling pathway is involved in cancer development and progression. EGFR inhibitors such as C225 (cetuximab), a chimeric human-mouse anti-EGFR monoclonal antibody, and ZD1839 (gefitinib), a small molecule EGFR-selective tyrosine kinase inhibitor, are in advanced clinical development. The potential emergence of cancer cell resistance...

Indexical appraisal of potentially toxic elements (PTEs) in sediment and fish riverine ecosystem give valuable information for environmental management. In this research, PTEs were measured soft tissues six species from an important breeding river (Halda) Bangladesh to assess quality human health risks. The abundance sediments varied the decreasing order Fe > K Ca Ti Zr Sr Rb Mn Zn Cu Ni Pb Co....

identifying the change trends in forms of land surface is one of the main topics in geomorphic system. in this view, we try to assess the stability level of geo systems, boundary changes, instability and prediction of surface forms and processes response. this paper tries to conduct a comparative analysis on the geomorphic equilibrium paradigms, critical thresholds, environmental and natural ha...

PURPOSE Immunostimulating Toll-like receptor 9 (TLR9) agonists cause antitumor activity interfering also with cancer proliferation and angiogenesis by mechanisms still incompletely understood. We hypothesized that modified TLR9 agonists could impair epidermal growth factor receptor (EGFR) signaling and, by this means, greatly enhance EGFR inhibitors effect, acting on both the receptor targeting...
