Don't want to get old? Set up the biological clock!

Perhaps, in addition to participating in the "tuning" of the biological clock, the per gene controls the mechanism that ensures the restoration of oxidative damage. Disruption of its functioning leads to accelerated aging, which can manifest itself in the development of a whole range of pathological conditions, including neurodegenerative diseases, cardiovascular diseases and cancer.

Testosterone against male aging: is it worth it?

If the protocols developed by specialists are followed, the administration of testosterone to patients with age-related hypogonadism is quite safe. At the same time, there is still no evidence that testosterone injections can prevent or slow down the development of signs of aging of the male body.

Poverty, stress, death... and genes

The risk of death from a heart attack or stroke 10-12 years after severe stressful situations is maximal in carriers of the most frequent variant of the interleukin-6 gene. Chronic stresses have a weaker effect on the health of people with rarer variants of this gene.

Ibuprofen for the prevention of parkinsonism?

Due to the pronounced side effects, doctors do not recommend this, although regular ibuprofen intake reduces the risk of developing parkinsonism by 40%. It is possible that studying the mechanism of action of ibuprofen at the molecular level will create a reliable and effective means of preventing Parkinson's disease.

Treacherous genes

Hundreds of human genes are involved in the development of viruses; inactivation of each of them noticeably slows down or stops the infection altogether. This information will be used to create new generations of antiviral drugs – inhibitors of certain human proteins.
