Heavy metal pollution of soils resulting from sewage and wastewater irrigation is causing major concern due to the potential risk involved. In the present study Musi River and its environs were assessed for heavy metal contamination. The study area was assessed for Zn, Cr, Cu, Ni, Co and Pb in soils, forage grass, milk from cattle,
PURPOSE. To understand the mechanisms mediating retinal ganglion cell loss in glaucoma, the gene expression patterns were compared for transferrin, ceruloplasmin, and ferritin between normal and glaucomatous retina in monkey and human eyes.
METHODS. Laser photocoagulation was used to produce unilateral experimental glaucoma in monkeys. Gene expression was assessed by in situ hybridization and quantitative reverse transcription polymerase chain reaction (PCR).
ABSTRACT: Mortality from cancer was reduced 90% during an 18-year follow-up of 59 patients treated with Calcium-EDTA. Only one of 59 treated patients (1.7%) died of cancer while 30 of 172 non treated control subjects (17.6%) died of cancer (P=0.002). Death from artherosclerosis was also reduced. Treated patients had no evidence of cancer at the time of entry into this study.
Total mercury concentrations (mean plus or minus standard deviation) in breast milk, blood, and hair samples collected 6 wk after delivery from 30 women who lived in the north of Sweden were 0.6 plus or minus 0.4 ng/g (3.0 plus or minus 2.0 nmol/kg), 2.3 plus or minus 1.0 ng/g (11.5 plus or minus 5.0 nmol/kg),
BACKGROUND: Methyl mercury (MeHg) and metallic Hg are well known as neurotoxic agents. Dental amalgam contributes significantly to elemental Hg vapour exposure in the general population. There is little information about Hg concentration in human amniotic fluid (AF) of pregnant women and its potential toxic effect on the fetuses.
OBJECTIVE: Primary to assess the relationship between the presence of detectable mercury (Hg) concentration in human AF,
In certain strains of mice, subtoxic doses of HgCl2 (mercuric chloride; mercury) induce a complex autoimmune condition characterized by the production of antinucleolar IgG Abs, lymphoproliferation, increased serum levels of IgG1/IgE Abs, and deposition of renal immune complexes. 4-1BB is an important T cell costimulatory molecule that has been implicated in T cell proliferation and cytokine production,
Mercury (Hg) has long been recognized as a neurotoxicant; however, recent work in animal models has implicated Hg as an immunotoxicant. In particular, Hg has been shown to induce autoimmune disease in susceptible animals with effects including overproduction of specific autoantibodies and pathophysiologic signs of lupus-like disease. However, these effects are only observed at high doses of Hg that are above the levels to which humans would be exposed through contaminated fish consumption.
Background This is a community comparison study that examines persons living in a subdivision exposed to petroleum products and mercury.
Methods We compared their health status and questionnaire responses to those living in another community with no known exposures of this type.
Results Pristane house dust among the exposed homes was higher than in the comparison communities.
Context: Myocardial infarction (MI) and strokes are leading causes of death in the US. Surgical and medical resultss can be helpful, but carry risks of morbidity and mortality.
Objective: To evaluate whether cardiac events were reduced for patients with known vascular disease who were treated with intravenous ethylene diamine tetra-acetic acid (EDTA) chelation .
Cadmium is a well-known human carcinogen and a potent nephrotoxin. Lipid peroxidation is involved in cadmium-related toxicity. Vitamin E and β-carotene are effective antioxidants and free radical scavengers. Therefore, the present study was carried out to investigate the potential protective effects of vitamin E and β-carotene alone or in combination against cadmium (Cd) toxicity. Cadmium chloride (CdCl2,
