Cardio-vascular Diseases (CVDs) - Essay Example This report is made with a view to analyze the important aspects of heart disease with clear examinations of the biochemical, body-functional and symptomatic areas of the disease and the presently available treatment models for the better understanding of all cardio-vascular disorders. Biochemistry of the Disease The defective condition of the heart results in the inferior level of blood flow with a considerably deficit in the supply of oxygen to body cells, and the impact of such a serious lack of the life giving gas results in the damage of the functioning of the brain in some cases. Cardiovascular illness can be attributed to a set of health issues occurring when the fitness of the circulatory system stars declining due to various health disorders. In the biochemical angle, heart disease is grouped into different categories such as arteriosclerosis, atherosclerosis, angina, heart attack and stroke. The condition of arteriosclerosis occurs when the arteries harden enough to lose th eir flexibility to carry blood proportionately. Atherosclerosis is the thickening of the interior walls of the arteries which results in the diminished blood supply quantity. Also, when the heart doesn’t get enough blood for the functioning, it piles up pains in the chest and this condition is called angina. Clotting of blood or other obstacles in the blood circulation creates partial flow of the blood, which results in heart attacks. The most dangerous of all the conditions is the insufficient supply of oxygen to the brain cells, and it causes strokes which can be partial or complete paralysis of the body in a permanent way. The identified reasons for the cardiovascular disease are hypercholesterolaemia, hypertension and cigarette smoking in most of the cases. The risk factors gradually contribute to the oxidation and arterial inflammation which in the gradual course result in the formation of fibroids or fatty lesions in the arterial interiors. Although there is assumption that genetically transmitted reasons can increase the risk of heart disease, personal healthcare disorder stands as the phenomenal cause for the illness of many people. The disease is diagnosed with the presence of inflammatory CRP (C-reactive protein) and the cardiac myofilament protein troponin which can directly cause heart failure (HF). As Scott points out, although the presence of calcium suppresses the HF, hypertension causes cardiac hypertrophy and permanent loss of cardiac cells. The protein synthesis that occurs with the oxidation process in the arteries results in the accumulation of atherosclerotic plaque and a resultant HF. As a results, monocytes stick to the endothelian cells and gradually cause the blockage of arteries with CD36 and SR-A (Scott). The continuous process of plaque weakening has an increased risk of initiating platelet recruitment which may even result in the production of sarcomeric proteins, an immediate cause of death. In all these conditions, the ult imate impact of the dysfunctions is reflected in the weakening of the cardiovascular cells to a fatal condition. Body systems Heart disease and body systems have a peripheral relationship in every angle, as the circulatory system is the life guard of the entire body cells. It is

Drug trafficking and drugs - Essay Example mechanisms in some countries, the presence of willing buyers and sellers, the strong cartels and finally the inherent problem of being a transnational crime. A drug has been described as anything that has a biological effect on a species, and that can be used for treatment, recreation, or for preventive measures. Most drugs that are prohibited are leisure drugs which tend to affect the brain of the user, and the prohibition is to encourage the promotion of responsible behavior among the youth who would take the drug to forget about problems. There are many forms of drugs, and there is usually a law in every country that regulates the use of drugs and identifies which drugs have been abused. Drug abuse is using drugs for non-intended purposes. There are many ways in which a person can gain access to drugs, but most drugs require the prescription of a qualified doctor (Lupton, 2012). The prescription has to be made after a diagnosis, so the disease or ailment can be effectively treated. There are also drugs that the law is lenient on; some of these drugs can be purchased over the counter. These are drugs for common ailments which do not have any adverse effect on the body, even when they are not taken in exact dosages. These are drugs for headaches, stomach aches, and for malaria in tropical countries. The danger with over-the-counter medication is that users are liable to develop a tolerance if the medication is overused. Finally, another form of drug is the prohibited drug, which can only be distributed through drug tra fficking and illegal sales (Hucklesby, 2010). Drug trafficking is the illegal transfer of a prohibited drug from one place to another. This is known as black market cartel whereby there are people who have dedicated their lives for the cultivation and production of illegal drug from countries that allow the growth and distribution of the drugs. In 2003 alone, the drug market contributed up to about 1% of the world economy, by producing
