Melation and Aging - Research Paper Example The level increases up to optimum when we are youths and latter starts declining. Many theories such as that from Hajak et al. (2003) have been put forward to explain the relationship between aging process and melatonin but none has explicitly explained the connection. This paper will explore some of the major issues involved in the hypothesis that melatonin can prolong and bring back the youthful memories. But in my findings, melatonin is just but a drug which can boost the melatonin hormone level in our body but not able prolonging or supplementing age. Introduction Melatonin is a hormone secreted in the brain from the amino acid tryptophan within the pineal. It is a naturally occurring compound and found in animals, human beings, plants and microbes. It was discovered in 1958 by Aaron Lerner and his colleagues. It is also called hormone of darkness simply because it is produced in darkness, highest percentage produced during night hours at bed side. It aging on the other hand mean s or it refers to post-maturational process that leads to decrease in homeostasis and increased vulnerability of the organism more so diseases. There has been close study on the relationship between the melatonin and the aging whether it improves or not. Zhdanova et al. (2006) claim that melatonin percentage in the body decreases as we grow old and their claims are just based on mere observation that older people do sleep less compared to younger ones. Their study also has explored other functions of melatonin not only the hypothesis but also what they termed as â€Å"a supplement to the aging but as a medicine to boost sleeping in aged people and also as treatment in† (pp. 899–907). Melatonin and Aging People all over the world wish to remain youthful and the issue of aging brings many problems and any solution to it will be gladly welcomed. Dollins et al. (2006) agree that theories and speculations relating melatonin and aging have been put forward but none of them h ave fully or clearly given their relationship. This compound no doubt is very vital in human life and one of study in the university of Granada, Spain carried out by Stone (2005) has proved that melatonin assist in controlling weight gain, also improves the blood lipids profile by reduction in triglycerides which increases level of good cholesterol HDL and at the same time lowering negative cholesterol called LDL. The general levels of melatonin vary greatly throughout one’s life span. The first time melatonin is created is when a child is three months old and that is when most people start to sleep. There is a rapid increase in the level and it peaks between the age of three and four years of age, this level fall back to a plateau and it remains constant throughout adulthood. The level starts to decline as we age up. The graph below shows circadian profiles of serum melatonin concentrations in human at various ages. Areas marked with black indicate period of darkness. By the time we are approaching seventies, the melatonin level decreases in our body to about a quarter of the original normal level when compared with time when one is young. It is thought that the drop may be associated with calcification of the pineal gland as we age

Smoking Should Be Banned Research Paper Example | Topics and Well Written Essays - 1000 words

Smoking Should Be Banned - Research Paper Example But is it about making money or ensuring good health for everyone in the society? Human beings should be able to choose life and health than unnecessarily expensive addictions like smoking and that’s why smoking should be globally banned. The human population is categorized into smokers and non smokers. Smokers are known to infringe on the rights of non smokers in the society (Cunningham 14). Their open smoking in public places like playgrounds, parks and beaches triggers coughing or asthma attacks from the passive smoking by in non smokers. The stench that comes out of the lit cigarettes also makes the open air ridiculously unbearable. Smoking increases the chances of sudden infant death syndrome (Hanson, Venturelli and Fleckenstein 42).Sudden infant death is when there is an explained death of an infant usually between two and four months. Smokers however forget that smoke is in gaseous form and therefore easily reaches children whose lungs have not properly developed. Smoki ng leads to lung, mouth, larynx, ladder, liver and other common cancers. It is also known to be largest cause of cancer deaths. For these reasons, there should be a decree that prohibits smoking. Banning of smoking is the basic move to make to show respect for every human beings right to free movement, association and right to admission to public places (Hudson 19).with this they are easily able to move freely without being scared of inhaling smoke that have adverse effects on their health. Air pollution is one the effects of smoking globally, it is the governments initiative to ensure that smoking is banned to ensure a balanced ecosystem for every living organism, including the smokers themselves. â€Å"The release of dangerous chemicals into the environment by smokers is the best definition of a selfish move† (Hudson 27). If the government is able to bar smoking, it will prompt the smokers to slow down, cut back and probably quit smoking because it will be harder to smoke o n the rise of a smoking urge. It makes sense for people to stop smoking all together because it a financial and health benefit to them. Smoking evidently is an expensive addiction. The most addicted smokers use up to two packets of cigarette daily, which will round up to an average of forty cigarettes in a day. Clearly this is not a cheap addiction to venture in. Smoking helps you save the money and spend on vacation with your family or live larger. In any case, a Wisconsin-based study carried out in 2002, 16%of the light smokers do it for recreational reasons. This will be the first to bail out in case of a ban. In as much as smokers think banning smoking is an infringement on their liberty as citizens, and that the government should not dictate how they live especially with the hefty amount of taxes they pay, it still stands that making laws that disallow smoking is beneficial to the society in that it protects patron and staff at a work place. Most employees have picked up smoke related diseases from their work places, sometimes because their workmates smoke. There is no law that [protects such people and that is why smoking should be banned. Usually in such cases, the employer sucks the employee in question and hires a â€Å"smoke tolerant person† leading to unemployment and one more addition to baseless decision ever mad because nobody is smoke- effects –proof (Hanson et al 20). As vague is sometimes sounds to most smokers, the bother of ones hair and
