Aug 31st, 2021 - Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) emerged as a virus with a pathogenicity closer to Severe Acute Respiratory Syndrome Coronavirus (SARS-CoV) and Middle East Respiratory Syndrome Coronavirus (MERS-CoV) and a transmissibility similar to common cold coronaviruses (CoVs). In this review, we briefly discuss the features of the receptor-binding domain (RBD) and protease cle...

Annals of Clinical and Laboratory Science; Nseir W, Njidat J et. al.

Aug 29th, 2021 - Clostridium difficile-associated diarrhea (CDAD) is a significant cause of mortality and morbidity in hospitalized patients. Several scores have developed in order to assess the severity of CDAD. To determine the role of the serum albumin to creatinine ratio (sACR) in predicting the 30-day all-cause mortality of patients with CDAD in comparison with other known severity scores of CDAD. A retros...

Aug 29th, 2021 - COVID-19, caused by severe acute respiratory coronavirus 2 (SARS-CoV-2), has presented a serious risk to global public health. The viral main protease Mpro (also called 3Clpro) encoded by NSP5 is an enzyme essential for viral replication. However, very few host proteins have been experimentally validated as targets of 3Clpro. Here, through bioinformatics analysis of 300 interferon stimulatory g...

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8391984
Physiological Reports; Singh J, Bhagaloo L et. al.

Aug 28th, 2021 - The spread of the novel coronavirus 2019 (COVID-19) has caused a global pandemic. The disease has spread rapidly, and research shows that COVID-19 can induce long-lasting cardiac damage. COVID-19 can result in elevated cardiac biomarkers indicative of acute cardiac injury, and research utilizing echocardiography has shown that there is mechanical dysfunction in these patients as well, especiall...

SARS-CoV-2 escape from a highly neutralizing COVID-19 convalescent plasma.
https://doi.org/10.1073/pnas.2103154118
Proceedings of the National Academy of Sciences of the Un... Andreano E, Piccini G et. al.

Aug 22nd, 2021 - To investigate the evolution of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in the immune population, we coincupi bated the authentic virus with a highly neutralizing plasma from a COVID-19 convalescent patient. The plasma fully neutralized the virus for seven passages, but, after 45 d, the deletion of F140 in the spike N-terminal domain (NTD) N3 loop led to partial breakthroug...

SCOPE enables type III CRISPR-Cas diagnostics using flexible targeting and stringent CA...
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8376896
Nature Communications; Steens JA, Zhu Y et. al.

Aug 21st, 2021 - Characteristic properties of type III CRISPR-Cas systems include recognition of target RNA and the subsequent induction of a multifaceted immune response. This involves sequence-specific cleavage of the target RNA and production of cyclic oligoadenylate (cOA) molecules. Here we report that an exposed seed region at the 3' end of the crRNA is essential for target RNA binding and cleavage, wherea...

Incentives can spur COVID-19 vaccination uptake.

Proceedings of the National Academy of Sciences of the Un... Klüver H, Hartmann F et. al.

Aug 21st, 2021 - Recent evidence suggests that vaccination hesitancy is too high in many countries to sustainably contain COVID-19. Using a factorial survey experiment administered to 20,500 online respondents in Germany, we assess the effectiveness of three strategies to increase vaccine uptake, namely, providing freedoms, financial remuneration, and vaccination at local doctors. Our results suggest that all t...

Proceedings of the National Academy of Sciences of the Un... Mirabelli C, Wotring JW et. al.

Aug 21st, 2021 - The global spread of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), and the associated disease COVID-19, requires therapeutic interventions that can be rapidly identified and translated to clinical care. Traditional drug discovery methods have a >90% failure rate and can take 10 to 15 y from target identification to clinical use. In contrast, drug repurposing can significantl...

The risk of indoor sports and culture events for the transmission of COVID-19.
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8376924
Nature Communications; Moritz S, Gottschick C et. al.

Aug 21st, 2021 - Nearly all mass gathering events worldwide were banned at the beginning of the COVID-19 pandemic, as they were suspected of presenting a considerable risk for the transmission of SARS-CoV-2. We investigated the risk of transmitting SARS-CoV-2 by droplets and aerosols during an experimental indoor mass gathering event under three different hygiene practices, and used the data in a simulation stu...

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8356449
European Journal of Medical Research; Kolben Y, Ishay Y et. al.

Aug 13th, 2021 - We present a case of bacterial endocarditis with both methicillin-sensitive and methicillin-resistant Staphylococcus aureus, which based on typing, originated from two distinct clones. Such a case may be misinterpreted by microbiology lab automation to be a monoclonal multi-drug resistant Staphylococcus aureus, while simple microbiology techniques will instantly reveal distinct clonality.
