What is the optimal dosing regimen for remdesivir in COVID-19 patients? A computational model

A team of scientists from the Pennsylvania State University, USA, recently analyzed the pharmacodynamics and pharmacokinetics of antiviral drug remdesivir using computational models. Based on the study findings, which are yet to be peer-reviewed, the scientists recommend that for effective inhibition of SARS-CoV-2 infection, remdesivir should be used with other antiviral medicines, or its dosing regimen should be optimized to improve bioavailability.

Is liquid chalk an effective disinfectant of SARS-CoV-2 and influenza viruses?

A recent study, published in the American Society for Microbiology’s journal, mSphere, evaluated the use of many liquid chalk products as antiseptics against the transmission of highly pathogenic human viruses such as influenza A virus (H1N1), SARS-CoV-2, (IAV), and norovirus in a mouse norovirus (MNV) model. The researchers applied chalk before or after virus inoculum and determined the recovery of infectious virus to mimic its use in the gym setting.

Researchers screen Chinese herbal medicines and plant compounds for anti-SARS-CoV-2 activity

A review published in Phytotherapy Research discussed the natural anti-SARS-CoV-2 products identified based on in silico prediction. The review’s authors also illustrate the impact of many phytochemicals either alone or in combination with traditional treatments and their potential molecular mechanisms involved in SARS-CoV-2 prevention and treatment.

Is Rand Paul mixing up the vaccine message for Covid survivors?

Last week, Sen. Rand Paul (R-Ky.) posted a Twitter thread asserting that people who have survived a Covid-19 infection were unlikely to be reinfected and have better immunity against variants than those who have been vaccinated against — but not infected by — SARS-CoV-2, the virus that causes Covid.
