After the new Corona virus has become a threat to the whole world about 12 months ago, since its appearance, all of us are looking forward to knowing what happens every minute, in light of the tremendous development that Covid-19 has brought in our lives.
Within this framework, “Masrawy” provides a daily service that includes displaying everything you want to know about the latest developments in the emerging corona virus, from the emergence of new symptoms or the occurrence of a different mutation, as well as the development of vaccines and drugs, in brief.
A technology that kills the virus in 30 seconds
Researchers from Tel Aviv University (TAU) have proven that the Coronavirus can be killed efficiently, quickly and inexpensively by using ultraviolet light-emitting diodes (UV-LEDs).
Researchers believe that UV-LED technology will soon be available for private and commercial use, according to “medicalxpress”.
The researchers tested the optimal wavelength to kill the coronavirus and found that the 285 nanometer (nanometer) length was nearly as effective in clearing the virus as the 265 nm wavelength, requiring less than half a minute to destroy more than 99.9% of coronaviruses, this result is important because it costs 285 nanometers. LEDs are much lower than those of 265nm bulbs, and the former are also more easily available.
Targeting these cells helps combat symptoms
For Covid-19 patients with severe lung disease, targeting endothelial cells – which make up the blood vessel wall that regulate oxygen exchange between the airways and the bloodstream – may be a new way to restore normal lung function.
This hypothesis stems from a study conducted by researchers in the Department of Microbiology and Immunology at Al Nahda School of Medicine at Stony Brook University in America, and published in mBio, the flagship journal of the American Society of Microbiology.
Beware the first ten days after leaving the hospital
An increasing number of studies have shown that in the first months after hospitalization due to coronavirus, patients face a high risk of persistent health problems, return to hospital, and death.
But the first week and a half could be especially dangerous, according to a new study published in JAMA by a team from the University of Michigan and the VA Ann Arbor Healthcare System, in the United States.
Covid-19 patients had a 40% to 60% higher risk of going back to hospital or dying in the first ten days, compared to comparable patients who were treated in the same hospitals during the same months for heart failure or pneumonia.
An intranasal vaccine trial
Pharmaceutical services company Open Orphan announced that it has received approval from the Independent Medicines and Healthcare Products Regulatory Agency (MHRA), and is ready to conduct the first phase study of the Covi-Vac, COVID-19 nasal vaccine, in cooperation with the American biotech company Codgenix.
Open Orphan will be assessing the safety and immunity of a single dose of the candidate nasal vaccine in 48 healthy adult volunteers at its facility in Whitechapel, London.
It is scheduled that a nasal vaccine against Corona will be subject to trials after it received approval from the Independent Medicines and Healthcare Products Regulatory Agency (MHRA) in the United Kingdom, which could mean a much simpler way to protect against the virus, according to the British “express” newspaper.
