Example Of Medicine Essay

Aging is a natural process that is generally viewed as unidirectional, and inevitable. However, data from a wide range of living organisms related to aging process suggests that environmental influences can be slowed so as to halt the aging process. The video reflects on different aspects related to aging and if it is possible to die without aging or aging without death, or are both essential. Aging is a process while longevity can be measures and both can be differentiated. The video asks an essential questions if how long an organism lives is related to how it ages. It is easy to understand that man would want longevity without aging and death. Are there ways to slow and reverse aging? There is clinical evidence that lifespan can be extended and aging slowed in every species by consuming fewer calories but taking adequate nutrition. There are ways to allows down aging but can one stop aging? There are examples given from lower species where they can stop aging by disconnecting with time and through preservation of biological processes in an arrested time. The video talks about how the effectiveness of cells repair and regeneration slows down with age. There are experiments whereby activating Notch signaling the muscle regeneration in an old muscle was the same as in a young muscle. Scion wonders if there are systemic regulators that program aged cellular phenotypes. It has been found that exposure of aged brim to a youthful environment rejuvenates the aged neural stem cells. Can cellular reprogramming promote rejuvenation? The video is based on recent experimental evidence suggests that cellular and functional characteristics of aged cell and tissues can be restored to a more youthful state. Current studies are focusing on understanding the regulation of those cellular mechanisms and how they can reset the aging clock.
