Exemplification Essay: Does Too Much Stress At Work

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.

Instead of losing telomeres after each reproduction, the cells replenish, or lengthen, the telomeres using an enzyme called telomerase.

Stress and anxiety in the average college student. Selye (1936) defined stress as “the non-specific response of the body to any demand for change” (The American Institute of Stress, 2017). Stress can lead to feelings of anxiety. Anxiety is a normal part of life, but can be considered a type of worry or fear that can inhibit everyday life. College students show higher stress/anxiety than average individuals. Major sources of stress are from new responsibilities, campus living, money issues, and classwork (Ross, Niebling, & Heckert, 1999). There have been a number of studies circled around how stress can affect college students. Females and males show differences in anxiety/stress in college. (Misra and McKean (2000)) found that females

The length of the telomere indicates age-related diseases, unhealthy lifestyle, and longevity in the lifespan.

In Chapter 27 “The Secret to Immortality” of The Immortal Life of Henrietta Lacks Rebecca Skloot provided an explanation to why HeLa cells were “immortal” unlike other mortal cancer cells; the p53 tumor suppressor gene had been “turned off” by the Human Papilloma Virus Lacks had. She mentions how according to the Hayflick Limit, human cell’s were able to replicate an average of fifty times. In addition, she explains how telomeres in cells shrink slightly every time the cell divides. According to Aging Cell’s 2004 article “The Cellular Lifespan and Senescence Signalring in Embryonic Stem Cells,” tumor cells “have high telomerase activity” yet they are not immortal. HeLa cells, similarly to Embryonic Stem (ES) Cells have the tumor suppressor gene p53 turned off. This differentiates HeLa from other tumor cells; while other tumor cells will replicated more than the average cell and eventually reach senescence, HeLa continues to replicate to this day thanks to the HPV virus that turned off its

Telomerase is able to add DNA nucleotides to the ends of telomeres (the end of DNA sequences). After replication, a small amount of the telomeres are cut off. When the telomeres are cut too many times, the cell has met its Hayflick limit. It is believed that when an individuals cells have divided too many times, that they die.

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,

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

Aging is actually the slowing process of cells: using less and less energy or entropy. As we age, our cells don’t regenerate as quickly as they used to. We slow down, our internal systems slow down and we just don’t generate the heat and energy of before. Entropy will envelope our closed system (cell) and it will just not produce as it should.

When scientists killed off a certain kind of cell that accumulates in the body with age mice were much healthier and lived about 25 percent longer. The mice didn't seem to suffer any ill effects from losing their so-called senescent cells,these are cells that have stopped dividing, they were though not necessarily because the cells themselves are old. "It's a normal cell that experienced an unusual amount of stress, and it decided to stop dividing," says Jan van Deursen, who studies senescent cells at the Mayo Clinic College of Medicine in Rochester,

We should balance telomerase not too high or not too low because telomerase are good for human cells to balance. People who don’t have enough magnesium than it can cause shrinking chromosomes.

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

Also spelled as ageing, this is generally the process of becoming old. It is the in a way the opposite of immortality. In a broader aspect, it may occur to single cells in an organism also called cellular senescence or the population of a species, known as population ageing. This process primarily affects human beings and fungi. In humans, it signifies the accumulation of various changes which occur over time. The changes include physical, social and psychological changes.

Aging causes structural and functional changes in brain. As aging population has become a burden, it is essential to study aging brain aiming to maintain cognitive integrity. Previous studies indicated that young blood improves the function of stem cells in organs including brain by heterochronic parabiosis model. However, data is lacking whether regeneration or beyond occurs by this model. The authors Villeda et al., hypothesized that aged animal exposed to young blood can counteract aging process and rejuvenate brain cognitive function. Therefore, the authors conducted research to examine within molecular, structural, functional, and cognitive aspects.

Humanity has come a long way as we evolve and adapt to the changing environment. Through the years, we have managed to overcome several limitations, which in the past were nothing more than dreams. We succeeded in landing on the moon and communicating over long distance, yet there are still some boundaries we have yet to cross despite our best effort. Aging is an inevitable process of nature. While we cannot stop the ticking clock in our body, we have made it possible for aging to be delayed and relieved to a great extent through advance technology and modern governance. High-tech equipments and medications are available for the treatments of more illnesses as our understanding of medicine improves and governments nowadays are doing
