Once the intimal layer of coronary artery is damaged‚ fatty deposits (plaques) made up of cholesterol and other cellular waste products tend to accumulate at the site of injury in a process called atherosclerosis. If the surface of these plaques breaks or ruptures‚ platelets will clump at the site to try to repair the artery. This clump can block the artery‚ leading to a heart attack. Recent research has

In 1991‚ the amyloid hypothesis assumed that beta-amyloid deposits are the fundamental cause of the disease. They eventually found a vaccine to take away amyloid plaques and used it on humans. It didn’t seem to affect the cause of dementia. The oldest hypothesis‚ the cholinergic hypothesis‚ hypothesizes that Alzheimer’s disease is caused by reduced synthesis of acetylcholine.

Atherosclerosis is a progressive disease of the large and intermediate-sized arteries characterized by accumulation of lipids and fibrous elements which cause development of fatty lesions called atheromatous plaques on the inside surfaces of the arterial walls; and is the single most important contributor to this growing burden of cardiovascular disease. Studies on the pathophysiology of this disease has evolved over the past three decades‚ and a fusion of

These bacteria are organised into a material known as dental plaque which is yellowish coloured film on the surface of the teeth. Of the many types of bacteria in the mouth‚ the most caries active appear to be Streptococcus mutans

The water on the slide helps to support the organism and sample. The water fills the space between the cover slip and the slide. This action allows the light from the microscope to pass through the slide and the sample for better visualization of the organisms. A direct stain occurs when a charged

Atherosclerosis is also known as an arteriosclerotic vascular disease‚ it is a condition were the arteries in the heart become hard‚ narrow and thick because of the buildup of cholesterol and plaque. Plaque is made of sticky material that is formed when cholesterol is combined with fat‚ calcium and fibrin (a clotting material in the blood) around the artery walls. Arteries have an endothelium‚ it is a thin layer which maintains the artery smooth and allows the blood to flow easily‚ Atherosclerosis
