Changes And Development Of The Aging Process

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.

Epigenetics is the study of cellular and physiological traits that are not caused by changes in the DNA sequence but they are triggered by chemical reactions that activate and deactivate parts of the genome and in specific locations. Therefore, epigenetics is the study of chemical reactions and factors that influence them. Hypothetically, epigenetics has the huge potential in terms of the uncovering genetic development of organisms, including humans, and the impact of chemical reactions that occur under the impact of various factors and affect genome activation and deactivation in specific locations. In this regard, further studies and development of epigenetics is essential but the impact and role of epigenetics should not be overestimated

Aging is a beautiful process that should be taking for granted. Growing of age should represent a well-preserved body and mind that exemplify the honor of the aging process. Conclusively, the aging process increases the quality of experience and the splendor of being magnanimous of aging. "The gray hair of experience is the splendor of the old" Proverb 20:29 (New Living Version).

Epigenetic (defined as reversible regulation of various genome functions, occurring without change in DNA sequence)(6, 7) , modification has recently emerged as one of the

My DRI varied from my current age, to being a ten year old school ager and finally ninety year old elderly women. My recommended daily intake didn’t change much between my current self, compared to my elderly self. But it did look like I did look like I could lessen my calorie intake with my fiber and carbohydrates. But with my ten year old self it showed that I needed more fat total K calories. As I aged, changes occurred in my body that could affect my nutritional needs. The aging process affects my body's absorption of many nutrients. For example, I’m less able to absorb nutrients such as calcium. My body also excretes, and eliminates, more nutrients.

with aging can be exasperating and chronic illnesses even so much more. Taking care of one’s

The purpose of this news is to notify us that scientists now understand better why aging occurs, researchers from the Institute of Molecular Biology (IMB) in Mainz, Germany found out that the genes which cause aging belong to a process called autophagy which boosts health and fitness in youth but drive the process of ageing later in life. It also demonstrates that ageing is something humans can not avoid. To do this research the researchers shut down autophagy in old worms and they saw there was a strong improvement in neuronal and subsequent whole body health. In the article of The tech museum of architecture they state that there are two theories of why we age, one is that our genes decide how long we live, and the other one says that as we live our DNA gets damaged until we can no longer function as we are supposed to do. They also talk about the experiment with the worms and how by mutating certain genes they can expand their lifespan up to 4-fold, which for humans would be the same as 300 years. There is another article were their research is about trying to prove that ageing is universal and is the same for all living things, however they found that is has many variables depending on the animal.

Aging process will lead to decline of biological functions and the ability to adapt to metabolic stress. Since the percentage of mortality increases rapidly with aging, it is clear that all of the body systems will changes in the individual which make him or her more vulnerable to disease. Among the systems that get affected by aging process are endocrine, cardiovascular, respiratory, musculoskeletal, and reproductive

Accumulation of both genetic and epigenetic deregulation results in genome alterations (10). Both of the gene mutations and epigenetic modifications have been initially considered as two separate mechanisms contributing to carcinogenesis. However, current evidence has revealed an interference between gene mutations and epigenetic modifications in cancer formation. Therefore, it has been suggested that gene mutations lead to distribution of several epigenetic patterns as well as mutagenesis and genome instability which can be mediated by epigenetic modifications (11, 12). For instance, whole exone sequencing of thousands of human cancer samples have shown unanticipated mutations in genes involved in epigenetic mechanisms which have the potential

The food we eat gives us nutrients, and these nutrients enter pathways where they are turned into molecules the body can use. There is one pathway that is responsible for making methyl groups, which are epigenetic tags that make genes unreadable. To show how not only our diet, but our parent’s diet can affect the epigenome and how methyl affects our epigenome, researchers looked at the diet of pregnant mice and observed how diet and methyl consumption affected their offspring. They looked at the agouti gene in particular, since it is a gene all mammals have. When a mouse's agouti gene has no methyl in it, the mouse has yellow fur, is obese, and is at high risk for cancer and diabetes. When the mouse’s agouti gene has methyl in it, the fur is brown and the mouse has a lower risk for diseases. The fat yellow mice and skinny brown mice are genetically identical. However, the fat yellow mice are different because they have an epigenetic "mutation." When researchers fed fat yellow pregnant mice with a diet full of foods containing lots of methyl in them, most of the babies had brown fur and were healthy. This shows that our health is not only determined by what we eat, but also what our parents ate.

The regulation of epigenetics plays a major role in development because it contains markers that control the expression

Over the last several years there has been much debate on the theories of aging. As we are aware, predicting how one will age, their life expectancy and when they will die is nearly impossible. However, researchers have separated the theories of aging into three main categories to help answer some of these questions and better understand the factors that influence the aging process. According to Edelman, Kudzma, and Mandle (2014), these are “biological theories of aging, sociological theories of aging and developmental theories of aging” (p.595). Of these, there are several theories that support each category. Researchers have identified the need to relate the aging process to one of these theories versus concluding that we die from old age

Biology of Aging is very different for each specific person and the way we age all happens at a different rate based on so many variables. Variables that have the possibility to cause humans to age are stress, genetics, diseases, and others. In this particular facility, I get to observe this first hand, especially working alongside the case mangers who deal with a wide range of aged patients. I think the general idea about aging before coming to college and becoming an aging studies major was that it was a bad thing. On the contrary I believe it is a great thing now, and there will be some exceptions to this only because everyone age differently. Some people die earlier than others and for many reasons. As my time passes by at CMC, I realize

The body of a human physically and mentally changes as we grow older. Once a person reaches adulthood, they begin aging causing the body to transform during the time of reaching maturity and the individual’s death. Physiologists have discovered that organs such as the heart, brain, kidneys, or lungs decrease in function as an individual’s life span increases. A younger individual’s body can fight off diseases better than an elder person. This is all due to the fact that as cells age, they function less as well.

Chapter 6, Youth and Aging, analyzes how age is percieved throughtout society as a whole. It looks at how the youth are treated and how the elderly are treated. I am very passionate about section 6.6, Problems of the Elderly, because I think we need to focus on giving support to the elderly. I think it is especially important as the dependency ratio is increasing and as the amount of elderly increase the amount of services they need will also increase.
