Heart attack or myocardial infarction occurs when there is an interruption of regular flow of blood to the heart. The blockage, which leads to the interruption of blood flow, has to be long enough that part of heart muscle dies or becomes damaged. This blockage makes the regular and required oxygen supply in the heart. This lack of oxygen supply leads to the death of numerous cells and the chance

Transplant Medicine The Major Histocompatibility Complex (MHC) contains over 128 functional genes. This is the densest part of the human genome and is responsible for most autoimmune diseases. This region also determines vaccine responsiveness, adverse drug reactions, disease progression and transplant rejection. The MHC genes are multigenic with a high degree of allelic polymorphism. There are over 7,500 different alleles and over 5,458 expressed MHC antigens currently known. (DeFranco, Locksley &

In theory, such evaluations could be useful, but as is, they are fairly useless. Plus, the validity and necessity of evaluations are up for debate themselves, besides the actual results from the evaluations being up for debate. Thus, the bioethical dilemma in those who abuse their bodies before and after receiving organ transplants lies not necessarily just with the recipients, but also with society, and with the medical field with

Asthma is an obstructive airway disease that is reversible. It is characterized by hyper-responsiveness of the airways, resulting in chronic inflammation and bronchospasm. Chronic bronchitis and emphysema are other examples of obstructive airway diseases that are reversible. (CH, 2011) Asthma can either be extrinsic, also known as atopic asthma, or intrinsic, which is also called non-atopic asthma. Extrinsic asthma is the more common variety, comprising of about seventy percent of all

This study indicates that some races are at higher risk of catching asthma when obesity is prevalent as compared to other races. This observation may help medical insurance companies to target these vulnerable groups of ethnic races. The study was helpful in further categorizing the chronic health issues of obesity and asthma with respect to its impact on each ethnic group. Though the result might not be able to generate
