One of the most interesting topics has been elaborated in this sqadia.com medical V learning lecture viz biochemistry of ageing. From shedding light on the process of ageing, ageing theories to an explication of factors influencing ageing have been broadly highlighted. Moreover, hormones of ageing, hormone replacement, effects of ageing including macular degeneration of eye, growth factors and role of dopamine receptors in ageing has been meticulously explained.
In this lecture ´´Biochemistry of Ageing´´ are explained. Section one is about ´´Ageing´´. Educator begins by explaining ageing. After that talks about ageing vs immortality. Then effects of ageing are reported. Moreover, life span and life expectancy is pursued. Secrets of ageing are also discussed.
Section two is about ''Ageing Theories''. At first, programmed theories are discussed. Then error theories are elaborated. This theory includes the elucidation of wear and tear, cross linking, free radicals, somatic mutations, errors in proteins, and genetic connection.
Factors Influencing Ageing
Section three is about ''Factors Influencing Ageing''. Earlier in this section, oxygen radicals are discussed. Then antioxidants and ageing gerbils are explained. Educator tells that high levels of antioxidants can slow the ageing process. This is followed by glucose crosslinking.
Section four is about ''Hormones''. Initially, educator introduces hormones. Then hormones of ageing are pursued. Hormones of Ageing involves estrogen, growth hormone, melatonin, testosterone, and DHEA (dehydroepiandrosterone). In the end, hormone replacement is discussed.
Effects of Ageing
Section five is about ''Effects of Ageing''. In the beginning, DNA repair is explained. After that heat shock proteins are elaborated. Following this, growth factors are reported. Then role of dopamine receptors in ageing comes under consideration. Next is the elucidation of macular degeneration of eye. Concluding comments are given on 7KC-atherosclerosis.
