Using Sotrovimab to treat COVID-19 early

A new study published on the medRxiv* preprint server hypothesized that a monoclonal antibody that has the capability to neutralize all sarbecoviruses could also be used to target a highly conserved epitope. This conserved sequence has a high probability of remaining unchanged in SARS-CoV-2 variants.

SARS-CoV-2 variants have higher transmissibility and a longer infectious period

Researchers analyzed data on three variants of concern and found that viral loads were higher and infection lasted longer for the B.1.1.7 variant. They all were more infectious than the original strain, and transmissibility also depended on population demographics.

Function and regeneration of dendritic cells impaired in COVID-19

A group of researchers from Germany has investigated and analyzed circulating dendritic cells and monocyte subsets in 65 hospitalized COVID-19 patients with mild to severe presentations of the infection. A variety of patients were included in their study, from those who exhibited minor signs of acute disease to convalescents, as well as healthy controls

Report on the effectiveness of mRNA-1273 and BNT162b2 COVID-19 vaccines in Canada

The report has recently been published on the preprint server medRxiv* by Kwong et al. (May 28th, 2021) and focused on the Pfizer-BioNTech or Moderna vaccines, confirming the supposed greater efficacy in preventing infection or severe outcomes following the administration of two doses.

SARS-CoV-2 variant B.1.617 may be more transmissible and pathogenic due to spike cleavage

In a new research paper currently available on the bioRxiv* preprint server, a research group from the United Kingdom (UK) provides experimental evidence that B.1.617 lineage of the severe acute respiratory syndrome coronavirus 2 (SARS‑CoV‑2) – also known as the Indian variant of concern – shows enhanced cleavage of spike glycoprotein by furin, which can […]

New material can enable a near-perfect merger between machines and the human body

Researchers at DTU Health Tech have developed a new material that can facilitate a near-perfect merger between machines and the human body for diagnostics and treatment.

Tai chi mirrors the beneficial effects of conventional exercise, study shows

A new study shows that tai chi mirrors the beneficial effects of conventional exercise by reducing waist circumference in middle-aged and older adults with central obesity. The study was done by investigators at the University of Hong Kong, The Chinese University of Hong Kong; Chinese Academy of Sciences; and UCLA.

Cognitive reappraisal may reduce compulsive drug-seeking behavior in cocaine-addicted individuals

An emotion regulation strategy known as cognitive reappraisal helped reduce the typically heightened and habitual attention to drug-related cues and contexts in cocaine-addicted individuals, a study by Mount Sinai researchers has found.
