Transcript of The Aging Process 2

The Aging Process
Science Option
The Aging Process
Insufficient information on aging
It's a process that affects everyone
Problem: There was not one specific factor that causes aging.
Resolution: Used any information that was available and created a museum exhibit to help the community better understand the aging process and it's theories.
We will discuss....
Background (i.e. topic, option, and why?)
What is aging?
Additional Background (i.e. exhibit)
Describe the aging process from a biological and physiological perspective.
Discuss the two main aging categories and their eight sub-categories.
Demonstrating poster & video
Additional Background
We chose...
UTEP Centennial Museum
Current exhibits rarely change
Adding a new exhibit introducing a interesting topic, such as the aging process would attract the UTEP and the El Paso community.
After researching our topic...
Not enough information on each sub-category
We decided to go into detail on two of the sub-categories and discovered there wasn't enough information to go into detail.
It was decided to go ahead and include all eight sub-categories within the two main theories to better explain that there is not just one theory contributing to aging.
We were successful in bringing the aging process idea as a general topic, even if we couldn't thoroughly explain the actual theories were.
At the beginning, we weren't sure how to go about the project/presentation.
It was unclear if all the elements of the project were to compliment one another, or
For example, if the poster was to illustrate one process and the video a different process.
Our documents usability would be average.
Because we've explained the overall concept of aging, but...
It wouldn't be great usability, because the actual information on the theories aren't enough to convince the audience of the theories.
With more time...
More research would of been conducted
Visit different dermatology clinics
Spoken to anti-aging doctors
Researched more in-depth each of the sub-categories
What is aging?
Aging begins from the day we're born until the day we die.
A reflection of the biological, physical, and psychological changes that occur throughout the course of one's life.
Everyone ages in different ways and paces.
Programmed Theory
Aging follows a biological timetable or a biological clock.
Aging will take place no matter what.
Programmed Longevity
Endocrine Theory
Immunological Theory
Programmed Longevity
Aging is a result of the sequential switching on and off of certain genes with senescence being defined as the time at which age associated deficits are manifested.
Endocrine Theory
Biological clocks act through hormones to control the pace of aging.
Hormones are chemical messengers located throughout the body via the bloodstream
The hormones are known as estrogen, testosterone, growth hormone, and melatonin.
These hormones decline with age.
Immunological Theory
A programmed decline in immune system functions leads to an increased vulnerability to infectious disease and thus aging and death.
Error Theory
Environmental assaults that damage cells and organs, causing them not to function properly.
Wear & Tear
Rate of Living
Free Radicals
Somatic DNA Damage
Wear & Tear
Cells and tissue have vital parts that wear out.
UV rays, radiation, toxins, and stress, to give life to this theory.
Damages cells, genes, tissue, and organs through the years.
Rate of Living
The greater an organism's rate of oxygen basal metabolism, the shorter its lifespan.
An accumulation of cross-linked proteins damages cells and tissues, slowing down bodily processes.
With increasing age, tendons, skin, and even blood vessels lose elasticity.
Due to the formation of cross-links between the molecules of collagen (a fibrous protein) giving elasticity to these tissues.
“Cross-linking” theory of aging assumes that similar cross-links form in other biologically important molecules, such as enzymes.
Cross-links could alter the structure and shape of enzyme molecules so they're unable to carry out their functions in a cell.
Free Radicals
Accumulated damage by oxygen radicals causes cells, and eventually organs, to stop functioning.
Somatic DNA Damage
Genetic mutations occur and accumulate with increasing age, causing cells to deteriorate and malfunction.
Particularly affecting the mitochondrial DNA, causing mitochondrial dysfunction.
Thank you!

Overall, while multiple theories of aging have been proposed, currently there is no consensus on this issue. Many of the proposed theories interact with each other in a complex way. By understanding and testing the existing and new aging theories, it may be possible to promote successful aging as well as to enhance the lifespan of mankind.
