Covid 19

Hemp is a source of fibre, food and animal feed, and multiple hemp extracts and compounds are added to cosmetics, body lotions, dietary supplements and food, said Richard van Breemen, a researcher at varsity. The team found that a pair of cannabinoid acids bind to the SARS-CoV-2 spike protein, blocking a critical step in the process the virus uses to infect people. The findings were published in the Journal of Natural Products.

Now, researchers from Yale University have developed a passive air sampler clip that can help assess personal exposure to SARS-CoV-2, which could be especially helpful for workers in high-risk settings, such as restaurants or health care facilities.The researchers developed a wearable passive air sampler, known as the Fresh Air Clip, that continually adsorbs virus-laden aerosols on a polydimethylsiloxane (PDMS) surface.

The snap poll had a sample size of 1,942. To a question if people were generally wearing masks and taking precautions, only 21.8 per cent of the respondents agreed that people were indeed wearing masks and taking precautions. In sharp contrast, 41.5 per cent said wearing of masks and other precautions were being followed "only sometimes" while another 33.8 per cent said they were mostly not being followed.

The whole SARS CoV2 virus infects an individual in natural settings, and elicits three kinds of responses - antibody mediated, cell mediated immunity, and immunological memory, he said.

The researchers said that Covid-19 vaccination of expectant mothers elicits levels of antibodies to the SARS-CoV-2 outer "spike" protein at the time of delivery that don't vary dramatically with the timing of vaccination during pregnancy and thus, don't justify delaying vaccination.

Kidney fibrosis, or scarring, is a serious long-term consequence that can occur virtually after any injury to the kidney and correlates with kidney function. The fact that the coronavirus can result in severe damage in the human body is known, and also that the kidneys can get infected. But what exactly happens in the kidney as a result of the infection, remains elusive until now.

The Zoe Covid study app asked hundreds of thousands of people to log their symptoms and the investigators have been looking at ones linked to both the dominant Delta variant and the new highly transmissible variant Omicron. The most common signs of the virus reported between December 3 and 10 were a runny nose, headache, fatigue, sneezing, and a sore throat, the Daily Mail reported.

In addition to being highly effective in preventing Covid illness of any severity, the vaccine was 100 per cent effective in preventing moderate and severe disease that required hospitalisation, revealed the study published in the New England Journal of Medicine. For the trial, the team from University of Maryland included nearly 30,000 adult volunteers at 113 clinical sites in the US and six sites in Mexico.

The research, published in the journal Frontiers in Cellular and Infection Microbiology, showed that male patients of blood group B are more prone to Covid-19 than the female patients with blood group B. People less than 60 years with blood group AB were found to be more prone to Covid infection. However, the study found no association between blood groups and susceptibility to severity of disease as well as mortality.

Scientists at the University of Nottingham in the UK found that the Delta variant, compared with other recent strains, showed the highest ability to multiply in cells, and was most able to directly spread to neighbouring cells. In co-infections with two different SARS-CoV-2 variants, the Delta variant also boosted the multiplication of its co-infected partners.
