Scientists and doctors have listed the nine processes that occur in our bodies with aging. These processes are inevitable, but their study can help to prolong youth.
“I don’t know of anything that improves with age, from a biological point of view.” This phrase expert of the Spanish National center for cancer research Manuel Serrano is not optimistic, informs UkrMedia.
Serrano is one of the authors of the study “Signs of aging”, in which experts list the main processes occurring in our body over time. “It is an inevitable factors. They can be more or less noticeable depending on the person’s lifestyle and genetics. But they always happen,” said Serrano in an interview with the BBC.
So, here are nine factors that indicate human aging.
Accumulated damage to DNA
Our DNA is a genetic code that is passed between cells. Aging leads to increasing errors that may occur in the process. These errors accumulate in the cells. This phenomenon is known as genetic instability and this is especially true for errors DNA in stem cells that form all other cells with special functions. Genetic instability could threaten the work of stem cells. With the accumulation of errors, these cells may become cancerous.
The DNA chain have lugs that protect our chromosomes – like the plastic tubes on the ends of shoelaces. They are called telomere. With ageing, these protective buffers wear down and the chromosomes lose their protection. This means that they are reproduced correctly, which causes problems. The researchers attribute the destruction tlarv disease type pulmonary fibrosis and aplastic anemia – a serious anal
