Programmed Theory of Aging

Aging      Image credit pixabay. Com Understanding the Programmed Theory of Aging:A Comprehensive Guide The mystery of Aging has puzzled humans for centuries. While we can't stop time, scientists have explored the theories that explain why we are growing older. One of the prominent idea is The programmed theory of aging, this theory suggest that aging is n't random, instead a process controlled by our gene.  The Enigma of Aging:A Biological puzzle Aging is a complex puzzle made up of many pieces. Each piece represent biological changes,environmental factors and life choices.  As we try to fit together, we realize that aging involve both our genetics and experiences Programmed Aging:A central Theory in Gerontology Programmed aging proposes that we have a biological clock ticking down through the life. This concept grounded in genetics, implying that our cells are pre-programmed to age and die. This theory stands in contrast to wear and tear theory. Which emphasiz...

Age Reversal By Gene Therapy

New Age reversal Technique: Gene Therapy Gene therapy                                  Image credit: Wikiped ia     Welcome to the journey into longevity science. Here genetical engineering is changing, how we fight  aging. we we'll explore age reversal and gene therapy's role in extending life and improving health.  Anti aging research and genetical engineering are merging.gene therapy lets scientists target aging causes,this could slow or reverse aging process.             We'll dive in to the age reversal science.We'll look at how cells aging,importance of biological signs, and role of DNA. We'll also see how Gene therapy has evolved,leading to today's age reversal methods.              Get ready for Longevity science ,we'll cover CRISPR, new gene delivery system,and choosing the right genes,we'll see ho...

Lipids&ageing

Cellinsight Everything about human ageing and related diseases Lipids Lipids are organic compounds, basically hydro carbons . They are non-polar ( means they don't have negatively or positively charged ends ) so they are not soluble in Water, but easily soluble in organic solvents such as chloroform, acetone, benzene,alcohol etc. Fats , oil , wax etc, are the examples of lipids . Lipids are necessary to make cell membranes, the outer most two layers of cell membrane is made up of phospholipids , which protect cell from surroundings and also helps cell more strong and flexible. Energy storage ( excess energy stored in adipose tissue in our body and used when ever needed ), they used to transmit nerve impulses, and many more..  Lipid metabolism Image credit goes to Commons.wikimedia.org           ( under common creative atribution)  Endocrine system in our body, releasing hormones which control growth and metabolism. According to their chemic...

The Hallmarks of aging

Aging- a Symbolic presentation What are The 9 hallmarks of Aging? According to the scientific world there are 9 reasons behind Aging, they are generally known as 9 Hallmarks of Aging. They are Genomic instability, Telomeres Attrition, Epigenetic Alteration, Loss of Proteostasis Deregulated Nutrient Sensing, Mitochondrial Dysfunction, Cellular senescence, Stem cells Exhaustion and Altered inter cellular Communications. genomic instability Genome is the genetical codes present in organisms. In other words genome is the complete set of DNA present in a cell. Every cell has  copy of the DNA. Genomic instability is the result of high frequency mutations ( sudden changes ) Because of  these mutations chromosome May rearranged, sometime the sequence of nucleic acids  or even the chromosome number May changed,( the chromosome number of human is 23 pairs, or 46 ).  Telomeres attrition Telomeres are the tail ends of chromosomes, which act as protective caps.

Effects of enzymes on aging and related diseases .

Effects of enzymes on aging and related diseases  Enzymes How enzyme catalyze a chemical reaction Enzymes are biological catalysts , catalysts are those substances which can alter the speed of chemical reactions.There are positive and negative catalysts, positive catalysts speed up chemical reactions where as negative catalysts decreases the rate of chemical reactions.Enzymes are positive catalysts, which accelerate chemical reactions in our body.Enzymes are basically proteins ,made up of long chains of amino acids .Enzymes are discovered in 1897 by a German biochemist Eduard Buchner , he got Nobel prize in chemistry in 1907 for his discovery of cell-free fermentation . He showed that an enzyme named zymase extracted from yeast cells can break up sugar into alcohol and carbon dioxide.There are about 40,000 different enzymes present in our body ( these number may increase because every day new enzymes are discovering )each enzyme catalyze a different chemic...

Role of protein on ageing

Protein structure  Role of protein on aging  Protein which controls the length of telomere are telomerase and a protein complex known as shelterin.a new study by Scripps Reserch Institute (TSRI) discovered a new protein named as TZAP (telomeric zinc associated protein)which decrease the length of telomeres by trimming,telomere is the clock of a biological cell,if it's length is too short the cell cannot multiply,a human cell can divide maximum 50 times,if it increase more, our life span may increase considerably. Certain proteins undergo oxidisation which are known to be associated with ageing and some age related diseases,when people turn about 80 approximately half of the bady proteins are damaged due to oxidation,the oxidation occurs because of random chemical degradation,that are associated with convertion of food particles to energy ( metabolism) . Protein's mis foldings are another reason for ageing,when native proteins are synthesised in our cells,whic...
