A diagnosis is confirmed by laboratory tests which show the presence of one or more abnormal circulating antibodies in the blood stream. These antibodies may be directed against any tissue in the body. The most important of these however‚ is an antibody directed against the centre or nucleus of the cells in the body‚ the so-called anti-nuclear antibody or ANA. ANAs are normally not present or present only in barely detectable quantities in healthy individuals. Thus‚ this test

Blood Components Normally‚ 7-8% of human body weight is from blood. In adults‚ this amounts to 4.5-6 quarts of blood. This essential fluid carries out the critical functions of transporting oxygen and nutrients to our cells and getting rid of carbon dioxide‚ ammonia‚ and other waste products. In addition‚ it plays a vital role in our immune system and in maintaining a relatively constant body temperature. Blood is a highly specialized tissue composed of more than 4‚000 different kinds of

Tuberculosis is a common‚ and in many cases lethal‚ infectious disease caused by various strains of mycobacteria‚ usually Mycobacterium tuberculosis. Tuberculosis typically attacks the lungs‚ but can also affect other parts of the body. It is spread through the air when people who have an active TB infection cough‚ sneeze‚ or otherwise transmit respiratory fluids through the air. Most infections are asymptomatic and latent‚ but about one in ten latent infections eventually progresses to active disease

Cancer Epidemiology Cancer is not a single disease; it is a myriad or collection of diseases with many different manifestations as there are many different types of tissues and cell types Cancer is a disease of abnormal gene expression. Cells are constantly evolving and have the natural selection pressures to change Common biological properties of tumor cells: 1) Deregulated clonal cell growth- all cells in a tumor originated from one single cell that acquired mutations that made it deregulated

white blood cells fight disease by producing antibodies and thus destroying foreign materia. The platelets help the blood to clot‚ if you get a wound for example. The plasma contains salts and various kinds of proteins. 2. What antigens and antibodies determine blood type? What are the antigens made of? The antigens and antibodies that determine the blood type are the A and B antigens‚ the Rh antigens‚ the A and B antibodies and the Rh antibodies. A and B antigens are sugars and the Rh antigens

purpose of this exercise is to gain knowledge and become familiar with the components of blood and blood cells. In order to do this‚ a prepared slide as well as a slide using my own blood were used. The different types of cells along with antigen-antibody reactions of the ABO and Rh blood groups were understood by examining and identifying the reactions of my blood with the reagents. The safety concerns associated with this exercise are properly handling and using the microscope so as not to

Breast Cancer: Introduction Breast cancer ranks as one of the leading cancer types in the number of new cases diagnosed and is second only to lung cancer as the the most prevalent cause of cancer death in women. In 2010 the American Cancer Society estimates approximately 209‚060 new cases of breast cancer will be diagnosed and 40‚230 deaths due to breast cancer will occur in the United States. It is important to note that men also develop breast cancer. Approximately 390 of the estimated deaths
