Nasal spray contains a chemical that can inactivate the coronavirus.

The nasal spray contains a chemical that can inactivate the coronavirus spike protein, which was produced by researchers at the University of Helsinki in Finland. TriSb92, the novel molecule, has been demonstrated to protect against coronavirus infection for at least eight hours in cell cultures and animal trials, even in circumstances of high exposure risk.

In contrast to vaccination protection, TriSb92's action begins very immediately after it is given.

"In animal models, nasally delivered TriSb92 provided protection against infection in an exposure condition when all unprotected mice were affected," stated Anna Makela, a varsity postdoctoral researcher. The findings have not yet been subjected to peer review.

The TriSb92 molecule is based on a completely new technology technique for targeting biological agents that was created in Finland. The solution was used in the study to stop the spike protein on the surface of the SARS-CoV-2 virus from working.
"Targeting the TriSb92 molecule's inhibitory impact on a region of the coronavirus spike protein that is common to all variations," Makela stated.

TriSb92 was able to stop the spread of SARS, the virus that attacked us in the early 2000s, in model viral tests.

"In other words, we may reasonably expect future varieties of SARS-CoV-2, and possibly even totally new coronaviruses, to be sensitive to it," Makela added.

The chemical might be used as a type of biological defence against coronavirus infection that is sprayed on the mucous membranes in the future if it is given as a nasal spray."

These sorts of infection-prevention chemicals, or antiviral medications for that matter, cannot replace vaccinations in safeguarding the population against the coronavirus sickness," stated university Professor Kalle Saksela.

However, there is a pressing need for new ways to improve the protection offered by vaccinations. "TriSb92 may be beneficial to patients whose vaccination protection is limited due to a variety of factors. It may also help fully vaccinated persons when given before any setting with a high chance of exposure, depending on the epidemic condition "Saksela said. (IANS/PR)

K'taka Hijab Row Triggers Debate.

By M.K. Ashoka

The issue of wearing a hijab (head covering worn in public by Muslim women) to the colleges along with the uniform has sparked a debate in Karnataka over religious practices impacting the education system in the state. The matter has also snowballed into a controversy on whether the hijab could be considered as part of the uniform. The ruling BJP is deliberating on whether to take a call on allowing hijab as part of the uniform of college students. State Education Minister B.C. Nagesh, while opposing the wearing of hijab to classrooms, has said that a decision would be taken on the issue soon by the government.

The experts as well as students are divided over the issue. Those who are in favour state that the dress code in classrooms should not indicate faith or religion as it creates barriers between students as well as teachers. Those who support the wearing of hijab say that hijab should be treated as a scarf. Hijab is black in colour and it can't be a religious symbol as Islam is identified with the green colour. The hijab should be treated as a symbol of chastity, they maintain.

The denial of permission to six girls in the Government Girls' Pre University College in the communally sensitive district of Udupi in the state has created a controversy. Nagesh dubbed it as a political move and questioned whether centres of learning should become religious centres. Meanwhile, the girl students have decided to continue their protest until they are allowed to attend classes wearing hijab.
