Oxygen is essential for human life, but within the body, certain biological environmental conditions can transform oxygen into aggressively reactive molecules called reactive oxygen species (ROS), which can damage DNA, RNA, and proteins. Normally, the body relies on molecules called antioxidants to convert ROS into less dangerous chemical species through a process called reduction. But unhealthy lifestyles, various diseases, stress, and aging can all contribute to an imbalance between the production of ROS and the body s ability to reduce and eliminate them. The resulting excessive levels of ROS cause oxidative stress, which can disrupt normal cellular functions and

Bulgaria should not exceed the critical daily threshold of 1,500 new Covid-19 infections, explained mathematician Nikolay Vitanov from the Bulgarian Academy of Sciences in an interview for BNT. In his view, 20% of the Bulgarian citizens have gone through Covid-19 until now. We can start talking about herd immunity when the number of people infected with the novel coronavirus reaches 800,000 or 900,000, said Professor Vitanov and added that Bulgaria was still far from herd immunity.

The masks with a valve and a filter protect only those who wear them, but not the people around them said Prof. Penka Petrova, director of the Institute of Microbiology at the Bulgarian Academy of Sciences.
This comes after a study of safety masks was conducted in Bulgaria. According to the new order of the Minister of Health from February 1 to April 30, it will no longer be allowed to cover the mouth and nose with a scarf or helmet instead of a mask.
It is permissible to wear cheaper disposable masks, as well as textile, and not necessarily more expensive and higher class FFP2, to which a number of European countries have switched. Prof. Penka Petrova reminded that the masks type FFP2 have a very high degree of protection.

Epilepsy, a neurological disease that causes recurring seizures with a wide array of effects, impacts approximately 50 million people across the world. This condition has been recognized for a long time written records of epileptic symptoms date all the way back to 4000 B.C.E. But despite this long history of knowledge and treatment, the exact processes that occur in the brain during a seizure remain elusive.
