Researchers have discovered that one of the good bacteria found in the human gut has the potential to reduce the risk of heart disease. The bacteria's activity in the intestines reduces the production of a chemical that has been linked to the development of clogged arteries, the study, published in the Journal of Biological Chemistry, said.
Is it safe to visit the dentist during the Covid-19 pandemic? Dentists can't eliminate all risk, but they are taking steps to minimize the chances of spreading the coronavirus. You'll likely notice changes as soon as you enter the office. Many dentists have removed magazines from waiting rooms, for example, as well as some chairs to encourage social distancing.
Neurological complications of Covid-19 may include delirium, brain inflammation, stroke, and nerve damage, according to a study which says some of these symptoms may not be a direct consequence of the novel coronavirus infection but due to the immune system acting on healthy cells.
The Indian Academy of Sciences, a Bengaluru-based body of scientists, has said the Indian Council for Medical Research's (ICMR) target to launch a coronavirus vaccine by August 15 is "unfeasible" and "unrealistic". The IASc said while there is an unquestioned urgent need, vaccine development for use in humans requires scientifically executed clinical trials in a phased manner.
More than 200 scientists from 32 nations have written to the WHO, saying there is evidence that the coronavirus is airborne and even smaller particles can infect people, a significant departure from the UN health agency's claims so far that Covid-19 is spread primarily through coughs and sneezes.
Researchers, including those of Indian-origin, have shown that the novel coronavirus can infect lab-grown cardiac muscle cells, indicating it may be possible for the virus to directly cause heart infection in Covid-19 patients. The study was based on experiments conducted in lab-grown heart muscle cells which were produced from unspecialised human stem cells.
Covid-19 is significantly associated with an increased risk of strokes, according to a study which says patients infected with the novel coronavirus should undergo aggressive monitoring for the neurological condition. According to the researchers, including those from the Icahn School of Medicine at Mount Sinai in the US, Covid-19 infection is a risk factor for acute strokes.
Increased physical activity is associated with a lower risk of obstructive sleep apnea -- a common sleep-related breathing disorder. The recent study was published as an accepted paper in the Journal of Clinical Sleep Medicine. It is the largest study to date focused on the relationship between sleep apnea and levels of physical activity in the general community.
A preliminary study of patients hospitalised with Covid-19 has found the disease can damage the brain, causing complications such as stroke, inflammation, psychosis and dementia-like symptoms in some severe cases. The findings are the first detailed look at a range of neurological complications of Covid-19, the researchers said, and underline a need for larger studies to find the mechanisms behind them.
