The Cell Theory Of Aging - 1813 Words

Introduction Every day we naturally lose skin and blood cells throughout our body; however, these cells are replaced through the proliferation and differentiation of stem cells found in pools throughout our bodies. Stem cells are found in most adult mammalian tissues, where they maintain normal tissue homeostasis and participate in tissue repair and regeneration in response to damage (Lui Rando 2011). The physiological process of aging may be the result of stem cell loss and a decline in the homeostatic and regenerative capacity of all tissues and organs (Lui Rando 2011). In fact, the stem cell theory of aging proposes that as we age, we fail to replenish the unique pool of stem cells. Consequently, this prevents us from replacing lost, differentiated cells and results in the inability to maintain and repair damaged tissues or organs. Therefore, it is important to understand the molecular mechanisms involved in the loss of stem cell function and find plausible solutions for treating age-related diseases. There are two classes of stem cells: embryonic stem cells and adult (or somatic) stem cells — this research will focus on the latter. Adult stem cells (ASC) are undifferentiated cells that can proliferate and differentiate into multipotent cells. Multipotent cells have the ability to give rise to multiple tissue types but are limited in their ability to indefinitely divide. Unlike embryonic stem cells (ESC), which are pluripotent and have the ability to divideShow MoreRelatedAging And The Aging Process1669 Words   |  7 Pages Aging, it’s something that as a species of life on this planet we are predisposed to and its results are an inevitable factor that effects our bodies in several ways, from cataracts development to the progression of memory issues from such diseases as Alzheimer’s or Huntington’s. The concepts of aging are broken down into two theories widely accepted by several varying fields of studies such as gerontology, the study of the aging p rocess, and oncology, the study of cancer and tumor development.Read MoreImmunological Theory of Aging Essay748 Words   |  3 Pagesshort lives, especially those to evade the aging process. With society becoming increasingly interested in everlasting beauty and living longer, the race to discover the main contributor toward aging begun in the early nineteen hundreds. In the midst of this quest, several biological theories had been developed. Among these theories is the immunity or immunological theory. This paper will discuss the immunological theory of aging by explaining the theory, giving a history of its origin and a descriptionRead MoreHow We Can Live Longer Essay1444 Words   |  6 Pages I.

Over the years many theories on aging have been developed and studied. Some theories are biological and some are psychosocial. This paper will depict a clinical situation, encompass the biological theory of aging, the wear and tear theory, and how it relates to the situation and the interactions employed by the Clinical Nurse Specialist (CNS). Clinical Situation James was a farmer, active every day of hisRead More Gaining Control of the Gene Responsible for Apoptosis Essay examples1141 Words   |  5 PagesGaining Control of the Gene Responsible for Apoptosis When we gain control of the gene responsible for the phenomenon of apoptosis, we will be in control of aging. We are finding more evidence every day, indicating genetic links to all sorts of factors in the human being. We are just now beginning to scratch the surface of our own genetics. A landmark discover has just been unveiled: In February [2001], the two groups charting the human genome published their results—the entire 3 billionRead MoreThe Cradle And The Grave And How We Are Affected By Our Genes1397 Words   |  6 PagesI will discuss the time that is between the cradle and the grave and how we are affected by our genes, free radicals, and everyday choices. The term â€Å"Aging† refers to in specific human beings, many animals, and fungi. Organisms such as bacteria, recurrent plants and some simple animals are theoretically immortal. Ageing can refer to single cells within an organism which have ceased dividing, also known as cellular senescence.

These units of energy are described by the Quantum Theory. The dictionary definition of the Quantum Theory is: â€Å"Any theory predating quantum mechanics that encompassed Planck’s radiation formula and a scheme for obtaining discrete energy states for atoms, as Bohr theory.† This definition means that Quantum Theory deals with Planck’s radiation formula, Bohr theory and indivisible units of energy.

Developmentalists look at adult physical functioning and begin to ask questions about loss or decline of function. There are two types of aging primary aging and social aging. Primary aging is age related physical changes tha t have biological basis. Social aging is age related changes due to environmental influences, poor health, habits or disease.

Excessive release of these metabolites induces longer period of mPTP openings creating a cycle that reduces one’s lifespan. Hagai Rotenberg and Jan B Hoek out of Thomas Jefferson University discuss how closely related aging and lifespan are to the prolonged opening of mPTPRead MoreEssay on Late Adulthood1394 Words   |  6 Pagesadulthood is known as the period of life after middle adulthood, usually from around 65 years old to death (Santrock, 2013, p. 485). There are many varying stages of development and health in late adulthood, along with steady changin g of life expectancy. Aging is a part of life, and with it comes changes in every area of living. Many diseases find late adulthood as an opportune time to affect people. Eventually, whether caused by disease or another reason, every individual dies. Death is unique to every
