The next 3 pictures are progressively worse indications. They reflect a loss of “electrical charge” of the RBC’s which causes them to stick together. Cells find it more difficult to transfer oxygen to tissues and to circulate freely. CAUSE: Too much cooked animal protein in diet, low digestive capacity, low HCL production and enzyme utilization, dehydration, diet not proper for blood type, cons...

Results The disease mainly affects males from poor socio-economic backgrounds who are involved in paddy farming . Mild proteinuria was present but urinary sediments were normal. Renal biopsies were reported as interstitial nephritis. Significant predictors of kidney disease in these patients included age, history of smoking, being under treatment for hypertension and drinking well water in the ...

Organic contaminants, volatile organic compounds (VOCs), and heavy metals have posed long-term threats to the ecosystem human health. Natural minerals aroused widespread interest in field of environmental remediation due their unique characteristics such as rich resources, environmentally benign, excellent photoelectric properties. This review briefly introduced contributions natural sulfide mi...

The Sebandoon Barite (gold-silver) deposit is located about 20 km NW of the Kashmar in the Central Iran. The rock units exposed in the area consist of Eocene volcano-sedimentary sequences of lithic tuff, rhyolitic tuff, tuffaceouce shale, lapilli tuff and agglomerate associated with pyroxene andesite and trachyandesite. The barite is composed of lenticular, banded and stockwork mineralization a...

Many heavy metals are essential for human biological functions, but some heavy metals, especially at high concentrations, can have toxic, carcinogenic and/or teratogenic effects in humans. South Africa is the world’s largest reserve of minerals and due to extensive mining activity, air and water pollution occurs [1, 2]. Metal exposure occurs mostly through the ingestion of contaminated water; u...

Phosphate-induced immobilization is recognized as one of effective in situ remediation methods for heavy metal contaminated soils. Phosphate-based minerals that adsorb, chelate, or complex heavy metals in soil were greatly concerned as effective heavy metals immobilizing materials. Effects of particle sizes of rock phosphate on immobilizing heavy metals in Pb-Zn mine soils by a greenhouse exper...
