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...

Animals who defeated ageing.

Cellinsight Everything about human ageing and related diseases Immortal animals Nothing is forever in this world, death is certain, one day it will visit us. But there are some creatures that never die by natural aging process. Human cells are capable of dividing only 50 times, later the cells entered the senescence stage, and this is the exact reason for aging. Any animal which is not experiencing senescence can defeat ageing, today I am going to tell about such types of animals and how they live without the fear of ageing 1. Jelly fish (Turritopsis dohrnii)  Immortal jellyfish (Image credit goes to Wikimedia )  Jelly fishes are sea animals, included in the phylum coelenterata (cnideria). Turritopsis dohrnii is a species of jellyfish which is known as immortal jellyfish. Jellyfish reproduce both sexually and asexually.The life cycle consisted of three main stages, planulae,polyps and medusae. fertilized egg give birth to planula. The  Planula is the larval stage...

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. I alread...

man man + O2 = Young man

Hyperbaric Oxygen Chamber Cellinsight.online Everything about human ageing and related diseases Old man + O2=young man      " Old man+O2=Young man" don't laugh I am not kidding you, this is the result of a new research conducted by Scientists from Tele Aviv University and Shamir Medical Center in Israel recently, and published in Aging magazine on 18th november 2020. The scientists claimed that they have managed to reverse the Aging. The scientists used Hyperbaric Oxygen chamber for conducting this experiment. The treatment inside the hyperbaric oxygen chamber is known as hyperbaric Oxygen therapy ( HBOT ). They selected 35 people who where above 64 years of age. Pure oxygen supplied to them inside the chamber, at various atmospheric pressure, They were treated inside the chamber for 90 minutes a day and five days a week, the treatment continued for 3 months. The result was mind blowing, the researchers found that the cellular level changes of the participants were equi...

Apoptosis and Necrosis, are they acceletate aging?

Cellinsight.online Everything about human ageing and related diseases Apoptosis and necrosis are they accelerate aging? apoptosis Apoptosis is programmed cell death. Apoptosis is a Greek word means "falling off".In a multicellular organism if cells are no longer needed,or it's DNA damaged and cannot be repaired,then the cells commits suicide by a process called programmed cell death or the Apoptosis. In human beings billions of cells die in bone marrow and intestine every hour .since 19th century scientists noticed and described about apoptosis but a clear definition was given by John Foxton Kerr at the university of Queensland in 1972.Later Hovitz,Sydney Brenner,and John E Samson identified the genes involved in apoptosis. In 2002  they got Nobel prize in medicine  Apoptosis and Necrosis In our body,cells are produced by cell multiplication (mitosis) and the apoptosis is used to the destruction of cells. Around 100,000 cells are produced in our body per second and...
