Study shows SARS-CoV-2 prompts NLRP3 inflammasome activation through spike-ACE2 receptor interaction

Neuroinflammation – a hallmark of neurodegenerative diseases, can be driven by a variety of triggers within the central nervous system (CNS). Such stimuli may include – pathogens, injury, toxic metabolites, and protein aggregates.

Study shows Omicron less severe than Delta among COVID-19 hospitalized patients

New research posted to the medRxiv* preprint server suggests the Omicron variant produces less severe COVID-19 symptoms than earlier severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variants. There was a 74% reduced risk of ICU admission, a 91% reduced risk of death, and no patients with Omicron infections needed mechanical ventilation. In addition, patients infected …

Study shows possible reverse zoonoses of SARS-CoV-2 from humans to animals

Severe acute respiratory syndrome-related coronavirus 2 (SARS-CoV-2) has been causing coronavirus disease (COVID-19), a pandemic that has been ruling our lives ever since early 2020.  The virus is a member of the coronavirus family, seven out of which (NL63, 229E, HKU1, OC43, SARS, MERS and SARS-CoV-2) are known to infect humans and all of these …

Omicron variant spike protein shows significantly weaker membrane fusion activity than other variants

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) Omicron variant has shown significantly higher transmission rates than other variants, despite lower rates of severe disease. Researchers from Harvard Medical School are investigating the membrane fusion activity and structure of the spike protein of this variant in order to better understand these differences. Study: Structural …

Study shows AI systems can accurately identify and grade prostate cancer

Researchers at Karolinska Institutet in Sweden have together with international collaborators completed a comprehensive international validation of artificial intelligence (AI) for diagnosing and grading prostate cancer. The study, published in Nature Medicine, shows that AI systems can identify and grade prostate cancer in tissue samples from different countries equally well as pathologists. The results suggest …

Study shows high acceptance of proactively treating partners of people diagnosed with chlamydia

Credit: CC0 Public Domain Chlamydia rates have been steadily increasing over the last 20 years, with women experiencing the highest burden of the infection. Expedited partner therapy (EPT) for chlamydia—proactively treating partners of people diagnosed with the infection—can be an important public health tool for stopping transmission of the infection. The approach is important especially …
