Senescence : The Cause And Effects Of Aging?

There are various genetic changes that people can experience the ill effects of that will presumably never be finished unless we effectively mediate and genetic engineering the cutting edge to withstand these issues. Case in point, Cystic Fibrosis, a dynamic and risky sickness for which there is no known cure, could be totally cured and annihilated with the assistance of particular genetic engineering, so it can almost never aging effect humans.

The elderly population is growing rapidly and now makes up greater than thirteen percent of the United States population. (APA, 1994). With such a record growth, there are different aspects to aging that are still being analyzed. Many may think of reaching late life as a rite of passage, but many face this time with a different view. Through the movie "UP', we are granted an opportunity into view the struggles of an elderly widowed man by the name of Mr. Fredrickson and the challenges in which he faces in his later life. The movie, takes one on a journey through his sorrows and his triumphs until he realizes what the true meaning of happiness is.

2. The MSNBC webcast recounts different stories of the aging population in America. One of the cases mentioned in the web cast is Arden peters and his wife Maxine. The aging theory of wear and tear can be applied to the case of Arden peters who has lost his wife Maxine due to dementia and Parkinson’s. He himself became too weak to care for himself due to the process of aging (MSNBC, n.d). He reached a point where he required someone to care for him. His friend Warren DeWitt is taking care of him and previously helped him take care of his wife until she passed away (MSNBC, n.d). The theory of wear and tear is based on the notion that aging is caused by damages done at the cellular level over time (Hawkley, Berntson, Engeland, Marucha, 2005). The processes that could damage the cells could be sickness, radiation, and accumulation of toxic materials over time

Humans undergo several stages during their lifetime including growth, development, reproduction and senescence. Senescence is defined as the deteriorative biological changes that organisms experience as they age eventually leading to death. These changes include low metabolism, a weak immune system, memory loss, poor vision and loss of hearing. Senescence begins in humans during their post-reproductive years. However, gerontology research has shown that individuals who reproduce late have longer life spans compared to individuals who reproduce early. Nonetheless, it does not indicate that senescence is inevitable. All organisms experience senescence,

(1) The theory that best support my current views on aging is the Wear-and-Tear Theory. The theory is “the idea that changes associated with aging are the result of chance damage to the body that accumulate over time”. (2) As many of us know, the body is constantly renewing itself. The cells in you is constantly creating new ones to replace the old, just like a boat. You are constantly restoring all the parts, where the boat will basically be almost all new parts. I think our body is like a built boat, car, or even a house, you must keep repairing it. Some people would literally get a new body part. A blood transfusion, heart replacement and a leg replacement are some examples of the theory. But just like a used car, boat or house, we stop

In order to better understand aging-associated diseases, it is first necessary to define what aging is. Aging is a complex, multifactorial process of harmful mutations in cells and tissues that are accumulated over time and result in an increased risk of disease and, eventually, death (Tosato, Zamboni, Ferrini, & Cesari, 2007, p. 401). Contrary to the belief that aging can be cured through medical advances, it is scientifically accepted that, while human life expectancy has increased, the human life span has remained largely unchanged for the past 100,000 years (Tosato et al., p. 401). Therefore, future developments in aging research ought to focus on addressing treatment and prevention of major aging-associated diseases that will

In the new age, aging is an event that has confounded biologists for the past several decades. With new advances in medicine, people are living longer than ever before and as a result are experiencing a new phenomenon known as aging, where there is deterioration of physiological functions that are required for survival and fertility over time. Now that people can live past 50 years of age, they are likely to develop grey hair, muscle deterioration, memory loss and slowed sexual responsiveness. While most organisms go through the aging process, there is no single hypothesis that explains how or why aging and senescence, the physiological deterioration, happens. In most organisms, there is a trade-off between the energy allocated for early growth

Everyone wants to stop the process of aging and man has been in search of a product that will help him. A few years ago, researchers found that aging occurs due to the reduction in production of the Human Growth Hormone in the body. As the body ages, the pituitary glands, responsible for the production of HGH, do not produce sufficient quantity of the hormone causing the many signs of aging to appear.

Despite the many theory's Science now knows that the body has a DNA called telomeres and over time with aging these telomeres become brittle.

I do not believe that there is one explanation to describe the aging process. Physiological change is based on different factors like a person’s genetic. Some people are born into different gene pools that makes the aging process different for people. In review of my own family history, my maternal great grandmother lived to the age of 104. I view her aging process as successfully. She was active and mobile. Her health was fair. Physically she appeared to be in decent shape. She was able to recall events and information. Her skin was not youthful, but for her age it was not wrinkled. Her emotional and mental health appeared composed. It was said that her mother age in a similar way. This leads me to believe that hopefully I too may age gracefully due to my genetic

Ageing, “the gradual decline in functions observed over time” (Rehman, 2016). Ageing is the result of genetic mutations that build up over time and make it harder for the cell to copy DNA. Every three nucleotide base pairs code for one amino acid, so by changing just one nucleotide can change the amino acid and the amino acid builds a different protein and that protein does a different job than was intended before the base pair change. The DNA copying that takes place in a cell during mitosis can be compared to a metaphor of a copying machine, one jam builds up and jams other copies and the machine doesn’t work as effectively. This paper jam is ageing, mitosis slows down and takes longer to produce cells and thus intern causes a domino effect,

The way God created us as humans is a life cycle where eventually late adulthood comes with the biology of aging. Santrock (2013) describes five different theories of why humans age (p. 541). The evolutionary theory explains that aging is more of a natural selection process, and diseases occur in the elderly because they “would have been eliminated” if they were in younger people (Santrock, 2013, p.541). Cellular clock theory describes how cells get tired of dividing after they have been reproducing for so long (Santrock, 2013, p.541). Free-radical theory explains when “cells metabolize energy the by-products include unstable oxygen molecules known as free radicals” (Santrock, 2013, p.541). The unstable oxygen molecules can damage DNA and other structures inside the cell (Santrock, 2013, p.541). Mitochondrial theory describes how aging occurs because of the mitochondria essentially wearing out and becoming less efficient (Santrock, 2013, p.542). Mitochondria are the cell’s “power house,” and they convert energy inside the cell (Bailey, 2008). The last theory, hormonal stress theory, illustrates the effects of stress, especially long term stress, on aging (Santrock, 2013, p.542). Stress released hormones which depress the immune system making people more susceptible to disease (Santrock, 2013, p.542). There are many theories about why human’s age, and all of them may be true, but regardless aging is inevitable and so are its effects.

Telomeres are directly correlated to the aging of a human body. Although some people might think that shorter telomere lengths are detrimental, the natural shortening of these telomeres are essential to healthy and normal aging. It is natural for cells to divide through mitosis, but each time cells are split telomeres are lost through the process. This is why the telomere maintenance system was evolved to protect the ends of chromosomes (Prescott, Kraft, & Chasman, 2011). Every time a cell is divided, its telomeres are weakened, and stress can accelerate this weakening, and biologically age the person. As a

Aging is the process of becoming older, as we age, multiple mutations occur that concern all the processes of aging well as it compromising a number of different genes. There are many theories of biological aging, such as the Cellular Aging Theory, Immunological Theory, and the Wear and Tear Theory. The Cellular Aging theory describes the process of aging in which cells slow their number of replication, thus giving each species a “biological clock that determines its maximum life span” and how quickly one 's health will deteriorate(Hooyman, 42). After a certain number of years, each cell which follows an apparent biological clock starts to replicate itself less, thus the specific individual or species slowly deteriorates. This theory gives

Causes of aging are very uncertain. Besides, there are several factors which predispose an individual to premature aging. Current theories suggest that this process occurs to due to cellular damage such as DNA oxidation by free radicals causing
