  • Aging Theories - 1,709 words
    Aging Theories This report outlines the main theories of how the process of aging works. Since researchers have not discovered a universally-accepted theory of aging, the theories discussed are potential explanations of how we age. The likelihood of each hypothesis is considered roughly equal. The different theories discussed focus on the workings of different parts of the body, from the molecular level of DNA mutations and replication, to the organism level of becoming "worn out." Aging is a very complex and gradual process, and its ongoing operation is present to some degree in all individuals. It is a journey to the maturity, as well as to the degeneration of the body. Because aging affec ...

Cellular Aging In 1961, a discovery made by Leonard Hayflick showed that normal, diploid cells from such continually Areplaced@ parts of the body as skin, lungs, and bone marrow, divide a limited number of times. Although the cells stop dividing at the point just before DNA synthesis, they do not die. The longer-lived the species, the more divisions the cells undergo. As the age of an individual increases, the number of potential divisions decreases (Ricklefs and Finch, 1995, 29). This discovery was found using fibroblasts, or cells found in the c ...

  • Alzheimers - 1,205 words
    Alzheimers Disease Alzheimers Disease is a progressive, degenerative disease that attacks the brain and results in impaired memory, thinking and behavior (Internet). It is a degenerative disease affecting nerve cells of the frontal and temporal lobes of the cerebrum of the brain. The disease is the major cause of presenile dementia (i.e., the loss of mental faculties not associated with advanced age) and is thought to be the largest single cause of senile dementia as well (Britannica, 306). It causes the connections between cells to become ineffective and the cells themselves to shutdown and eventually die (Davies, 1). Alzheimers is a progressive, irreversible, fatal neurologic disorder that ...

  • Alzheimers Disease - 1,539 words
    Alzheimer`s Disease Alzheimers Disease is a progressive, degenerative disease that affects the brain. Individuals with AD experience a progressive and specific loss of cognitive function resulting from the differentiation of the limbic system, association neocortex, and basal forebrain. It is also accompanied by the deposition of amyloid in plaques and cerebrovasculature, and the formation of neurofibrillary tangles in neurons. Alois Alzheimer, a German doctor, diagnosed this disease for the first time in 1907. At that time it was considered a rare disorder. Currently, this tragic brain disorder affects approximately four million people; It is the most common type of dementia and the fourth ...

  • Alzheimers Disease - 1,004 words
    Alzheimer's Disease Dementia is the loss of intellectual and social abilities severe enough to interfere with daily functioning. For centuries, people called it senility and considered it an inevitable part of aging. It is now known that dementia is not a normal part of the aging process and that it is caused by an underlying condition. People with this condition need special assistance to carry on with their normal lives. This paper will explain some of the social services that are helping to combat this disease and an analysis of the services effectiveness. More than four million older Americans have Alzheimer's, the most common form of dementia. And that number is expected to triple in th ...

Genetics The most popular genetic theory, the Error Theory, assumes that aging is the result of the accumulation of random genetic damage, or from small errors in the flow of genetic information. The damage or errors would reduce or prevent proper cell function. Cellular The best known theory of aging in cellular research is called the Hayflick Effect, which is named after the American microbiologist ...

  • Benefits Of Physical Fitness - 534 words
    Benefits Of Physical Fitness Benefits of Physical Fitness Physical Fitness has many positive benefits for a person's body. Exercise provides health benefits, increases strength and energy, enhances a person's appearance, which helps with self-esteem and also relieves stress. A major health benefit from exercising is reducing the risk of heart disease. Exercise will help increase the HDL (good cholesterol) to LDL (bad cholesterol) ratio. Estimates are that 96.8 million American adults (51 percent) have blood cholesterol values of 200 mg/dL and higher. About 37.7 million American adults (20 percent) have levels of 240 or above. By having physical activity, the efficiency of the heart and lungs ...

  • Cloning - 918 words
    Cloning Cloning In the past few years, the topic of cloning has been in the news a lot. It is a very controversial issue, with many opposing viewpoints. While some find it acceptable, others object for religious reasons. A big concern is the possibility of abuse of this new technology. One of the big questions is Where will we stop? We may start by just experimenting and studying, but then what? Manufacturing human bodies for spare parts? No one can be sure where it will stop. The Supreme court says that everyone has the right to make their own reproductive decisions without government interference, but now it is proposing bans on human cloning. These bans prevent the very research needed to ...

  • Cloning Or Clowning - 436 words
    Cloning Or Clowning? Cloning or Clowning Around? Just like in the fictional book Jurassic Park they cloned dinosaurs for the purpose of entertainment. They thought they could control them like zoo animals, but they were wrong. They also only made female dinosaurs so that they couldn't reproduce, but in the end nature found a way. A big draw back and reason that cloning should not ever occur is the accelerated aging process. Dolly, the first cloned mammal seems to be aging faster than normal. The faster aging of a human may have some great impacts on the mind. The mind could be at a sixth grade level of education, but the body could appear to be older than the parent's body. If we start to cl ...

  • Cloning Pluses - 732 words
    Cloning Pluses Have you ever imagined what life would be like if we could eliminate human problems? This is the question that arises when the issue of cloning is brought up. Cloning is the process where by organisms, cells, or microorganisms are copied to produce an almost identical genotype. Cloning is beneficial to humanity. It can help solve organ limitations, cure diseases, and take a giant step forward toward immortality. One of the strongest reasons to support that cloning is beneficial to humanity is that there would be a solution to organ limitation. One of the greatest problems in medicine today is that many people need organs for various reasons, which are not available. This creat ...

In addition to the success, "the US National Institute of Health consensus conference highlighted the need for continued development in this area (January 1997)." The types of psychological treatments used on the elderly are specifically designed for aged persons. The central idea in cognitive therapy is to take the negative self-opinion and teach ways to reverse this opinion. Validation and reminiscence are examples of techniques used to get the patient to reflect on the accomplishments of his or her lifetime. Hopefully, this will bring back some pleasant memories of family or other accomplishments. It also allows the patient to look at the ...

    Frankenstein By Shelley Frankenstein, by Mary Shelley is a complex novel that was written during the age of Romanticism. This gothic work has enjoyed a wide range of interest and readership for roughly 200 years.
