exposure to mercury (hg) as a heavy metal can cause health effects. the objective of this study was to assess occupational exposure to hg in a chlor-alkali petrochemical industry in iran by determining of hg concentrations in air, blood and urine samples.the study was performed on 50 exposed subjects and 50 unexposed controls. air samples were collected in the breathing zone of exposed subjects...

To test the hypothesis that increased osmolality contributes to hypertension in deoxycorticosterone acetate (DOCA)-salt-hypertensive rats by acting in the brain, DOCA-salt and Sham-salt rats were instrumented with bilateral, nonoccluding intracarotid and femoral catheters. Two weeks prior, rats were uninephrectomized and received subcutaneous implants with or without DOCA (65 mg) and began drin...

Background: The Present study was carried out to track and calculate Biomagnification Factor (BMF) of total mercury (T-Hg) between two different trophic levels (i.e., plankton and a planktivorous fish) in a fresh water grazing food chain. Methods: Experimental organisms were planktonic biomass and silver carp (Hypophthalmichthys molitrix) as a planktivorous fish. Silver carp samples were obt...

Myeloid cell lines and primary leukemic myeloblasts express two classes of granulocyte macrophage colony-stimulating factor (GM-CSF) binding sites of high (Kd 20-50 pM) and low affinity (Kd 5-10 nM). High affinity binding is caused by the association of two chains, p80 alpha and p130 beta, whereas p80 alpha alone confers low affinity binding only. Furthermore interleukin-3 (IL-3) competes for t...
