Surgical masks effectively reduce outgoing airborne particles, despite leakage at edges

A new study from the University of California, Davis and the Icahn School of Medicine at Mount Sinai confirms that surgical masks effectively reduce outgoing airborne particles from talking or coughing, even after allowing for leakage around the edges of the mask. The results are published June 8 in Scientific Reports.

Cyperus rotundus medicinal plant shows promise for novel COVID-19 therapeutics

Cyperus rotundus is a plant with a history as herbal medicine, containing many chemical substances frequently found to be drug-like in character: flavonoids, terpenoids, and the like. Compounds sourced from the plant have demonstrated some inhibitory activity against HIV by modulation of the CYP3A4 enzyme, and thus in a drug lead discovery effort, Kumar et al. (July 2021) computationally screened these natural compounds against MPRO in a paper recently published to Computers in Biology and Medicine.

Potent antibody responses to BNT162b2 COVID-19 vaccine among Japanese healthcare workers

In a paper recently uploaded to the preprint server medRxiv* by Nakajima et al. (June 4th, 2021), the antibody responses of over 2,000 Japanese healthcare workers were tracked over a period of several months, with particular regard to serum Immunoglobulin G (IgG) against the SARS-CoV-2 spike protein.

Unused Johnson & Johnson Covid doses are piling up as FDA waits to see if shelf life can be extended

The Biden administration is encouraging states to hold on to hundreds of thousands of soon-to-expire Covid vaccine doses from Johnson & Johnson, given the possibility that additional data will show the shots are viable beyond their expiration date at month's end.

Antihistamines might be effective in long-COVID

A team of scientists from the United Kingdom has recently revealed the therapeutic benefits of histamine receptor antagonists in reducing long-term symptoms of coronavirus disease 2019 (COVID-19). They have also indicated that T cell immune responses to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection vary between asymptomatic COVID-19 and long-COVID.

Are women more likely to develop long COVID?

Researchers found different groups of symptoms persisting after coronavirus disease 2019 (COVID-19), with fatigue and higher IL-6 levels common in women. About 75% of the patients they treated were women, indicating a link between sex hormones and immune response.

Study reveals personal stigma and discrimination towards people living with HIV

Forty years ago, the first cases of HIV/AIDS in the U.S began to raise public awareness- but new research highlights the struggle people living with the disease still face against stigma, discrimination and negative labeling in their own families, communities and even amongst healthcare professionals.

MIT researchers develop a molecular assay to detect sub-picomolar levels of the SARS-CoV-2's receptor-binding domain

A team of researchers at MIT has developed a molecular assay to detect sub-picomolar levels of the SARS-CoV-2’s spike protein receptor-binding domain (S-RBD) using computationally validated peptide beacons in a single-step detection through the production of a fluorescence signal.
