Reverse ageing process

Issue

A group of scientists from Israel have managed to reverse the process of ageing in what is being hailed as 'breakthrough research'.

 

Background

Researchers concluded that by doing so they were able to not only stop but also reverse two processes related to illness and ageing.  

 

Details

  • The team treated the cells in a pressure chamber with high-pressure oxygen. They were able to not only halt the ageing process but reverse two major processes associated with ageing and its illnesses.

  • The first one was the shortening of telomeres (cap-like structures present in chromosomes) and the other was an accumulation of old and malfunctioning cells in the body.

  • About 35 adult human beings who are more than 64 years old were part of the study. All of them were given Hyperbaric Oxygen Treatment (HBOT) for 90 minutes a day, five times a week for three months.

  • The subjects were found to have improved attention, information processing speed and executive functions.

  • The study discovered a lengthening of up to 38 per cent of the telomeres, as well as a decrease of up to 37 per cent in the presence of senescent cells.

 

Telomere

A telomere is a region of repetitive nucleotide sequences at each end of a chromosome, which protects the end of the chromosome from deterioration or from fusion with neighbouring chromosomes.
