One year old male infant named Matthew is brought into the clinic by very worried parents. Infant shows abnormal symptoms such as stunted growth and underdevelopment of weight for his age and he has no hair on him‚ a condition called alopecia. Alopecia in his case took off all the hair off his head and his eyebrows and eyelashes. Infant’s head was severely disproportioned to his body and also was disproportioned to his face. His face appeared to be very shrunken and small and he had an underdeveloped

it is possible to apply this method to prolong human life. Since then‚ the theory of negative aging or also negative senescence was established. “Senescence is the scientific term for what we commonly think of as aging.” With normal aging‚ the terms of human health are weakened‚ the function of the senses decrease markedly‚ the skin changes appear. However‚ in the negative senescence theory‚ the risk of death decreases markedly when the plants grow up over the years. This does not mean that the plants

Abstract The mechanisms that regulate cellular senescence‚ organismal ageing‚ and species-specific lifespan depend on a synergy of pathways that are multifactorial and extremely complex‚ though not yet completely understood. Recently‚ the development of new molecular techniques has elucidated‚ at least

Ageing (British English) or aging (American English) is the accumulation of changes in a person over time.[1] Ageing in humans refers to a multidimensional process of physical‚ psychological‚ and social change. Some dimensions of ageing grow and expand over time‚ while others decline. Reaction time‚ for example‚ may slow with age‚ while knowledge of world events and wisdom may expand. Research shows that even late in life‚ potential exists for physical‚ mental‚ and social growth and development.[2] Ageing

to living organisms that induce cumulative damage at various levels as the cause of aging. The programmed theory has three sub-categories: 1) Programmed Longevity. Aging is the result of a sequential switching on and off of certain genes‚ with senescence being defined as the time when age-associated deficits are manifested. Dr. Davidovic et al discuss the role of genetic instability in aging and

The aging brain is slowing down during these years‚ which Senescence reduces the neurotransmitters-glutamate‚ acetylcholine‚ serotonin‚ and dopamine-that allow a nerve impulse to jump quickly across the synapse from one neuron to another (Backman and Farde‚ 2005.)

Cellular aging therefore‚ can be described as an increased susceptibility to cell death caused by the loss of cellular functions such as cell division‚ cell communication‚ transport and delivery. A cell ages gradually until it gets to the senescence stage which is a process by which a

De Grey leads the Strategies for Engineered Negligible Senescence or SENS and has come up with seven plausible causes of aging and thinks that they can all be fixed (Than “Hang in There” 2). Step one of the process is stopping aging in mice because they are mammals just like humans. De Grey believes the research

The Ultimate Anti-Aging: Effects of Exercise to Telomerase Activity Abstract Exercise or constant activity has always been the last word or among the first recommendations in countering the signs of aging. The aging that has been associated with exercise is termed as biological age and is used to mean as our age that is physiological rather than chronological‚ and it includes factors like changes in the physical structure of the body as well as changes in the performance of motor skills and sensory
