Water is never ’pure’ in a chemical sense. It contains various kinds of impurities such as dust particles‚ dissolved gases‚ dissolved minerals‚ microscopic paints and animals‚ suspended impurities and bacteria. These are natural impurities derived from the atmosphere‚ catchments area and soil. Besides this‚ there are various other reasons by which water i9 polluted. The upland surface water derives its impurities from the catchments area‚ the sources being human habitations and animal keeping

Cardiovascular System (Simplified) The cardiovascular system includes the heart and the blood vessels. The heart pumps blood‚ and the blood vessels channel and deliver it throughout the body. Arteries carry blood filled with nutrients away from the heart to all parts of the body. The blood is sometimes compared to a river‚ but the arteries are more like a river in reverse. Arteries are thick-walled tubes with a circular covering of yellow‚ elastic fibers‚ which contain a filling of muscle that absorbs

Stroke Pathophysiology Sid Shah‚ MD Pathophysiology of Stroke Sid Shah‚ MD Page 2 of 14 Stroke Pathophysiology Introduction The two major mechanisms causing brain damage in stroke are‚ ischemia and hemorrhage. In ischemic stroke‚ which represents about 80% of all strokes‚ decreased or absent circulating blood deprives neurons of necessary substrates. The effects of ischemia are fairly rapid because the brain does not store glucose‚ the chief energy substrate and is incapable of anaerobic

then the use of saline would avoid patient exposure to heparin-associated risks such as hypersensitivity reactions‚ local tissue damage‚ bleeding‚ and heparin induced thrombocytopenia (HIT). Saline will also increase the accuracy of the patient’s coagulation profile‚ enhancing patient management. And saline is more cost effective for institutions. But there are some studies that have shown an increase in infections when using saline over

Aetiology The aetiology of atherosclerosis is not fully understood‚ but there are certain factors that contribute to atherosclerosis plaque progression. These include genetic and acquired factors. The processes involved in atherosclerosis include coagulation‚ inflammation‚ lipid metabolism‚ intimal injury‚ and smooth muscle cell proliferation. Certain risk factors have also been identified to explain the development of atherosclerosis and these can be separated into two groups‚ genetics and environmental:

Typical assays include blood glucose testing‚ blood gas and electrolyte analysis‚ coagulation testing‚ cardiac marker diagnostics‚ drug screening‚ urine dipsticks‚ pregnancy testing‚ fecal occult blood analysis‚ food pathogen screening‚ hemoglobin diagnostics‚ infectious disease testing‚ and cholesterol screening.1 The most common POCTs used in US hospitals include glucose (99%)‚ coagulation (62%)‚ blood gas (50%)‚ chemistry (36%)‚ hematology (28%)‚ urinalysis (15%)‚ and cardiac (3%)
