New approach to reveal high-resolution protein structural details

The number of proteins in the human body, collectively known as the proteome, is vast. Somewhere between 80,000 and 400,000 proteins circulate in our cells, tissues and organs, carrying out a broad range of duties essential for life.

Self-isolation on arrival at airports dramatically improves detection of disease importation

Researchers from Public Health England have conducted a study showing that screening and quarantining travelers on arrival at airports significantly reduces the risk of disease importation during international outbreaks, compared with screening alone.

Low lymphocyte count before COVID-19 heightens death risk

Researchers at the University of Rochester Medical Center have conducted a study suggesting that having a low white blood cell count (lymphocytopenia) prior to exposure to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) may be associated with an increased risk of dying from coronavirus disease 2019 (COVID-19).

Antigen testing detects SARS-CoV-2 better than PCR

A team of scientists from the United States demonstrates that rapid antigen tests for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) are more effective in determining the actual infection status in patients with coronavirus disease 2019 (COVID-19) than real-time polymerase chain reaction (RT PCR)-based tests.

Analysis: ‘Don’t be afraid of COVID’? Not buying it, unless businesses do job right

As stores, restaurants, airlines and offices try to lure clients back, this is what they need to do to earn my business: Make me feel safe — no, make me be as safe as possible. As I've begun to explore old haunts, some are doing a fabulous job. Others are not.

Easier-to-use coronavirus saliva tests start to catch on

As the coronavirus pandemic broke out across the country, health care providers and scientists relied on the standard method for detecting respiratory viruses: sticking a long swab deep into the nose to get a sample. The obstacles to implementing such testing on a mass scale quickly became clear.

Campus dorm resident assistants adjust to a new role: COVID cop

Breaking up parties, confiscating booze and answering noise complaints — being a resident adviser has always required a willingness to be the "bad guy" and uphold university policy despite the protests of friends and peers.

Supercharged "clones" trigger the re-emergence of scarlet fever

A University of Queensland-led team of international researchers says supercharged "clones" of the bacteria Streptococcus pyogenes are to blame for the resurgence of the disease, which has caused high death rates for centuries.

Older heavier COVID-19 positives likely to be superspreaders

The spread of SARS-CoV-2 is known to be through respiratory droplets as well as via aerosols, composed of minute particles normally exhaled during natural breathing.

SARS-COV-2 traveled from China to West Africa directly or via Europe

With the onset of COVID-19, the focus of medical research has been on tracing the origin of SARS-CoV-2, which was first reported in China’s Wuhan city.

SARS-CoV-2 prevalence in England “Higher than at any time from May 2020.”

The UK was badly hit by the COVID-19 pandemic, with the numbers of patients requiring hospitalization high during the first wave of the infection.

Plasma ACE2 concentration associated with increased risk of major cardiovascular events

A team of scientists at the Population Health Research Institute, Hamilton Health Sciences, and McMaster University, Hamilton, in Ontario, Canada, revealed that increased plasma ACE2 levels in the blood could indicate a higher risk of major cardiovascular events. The study is published in the journal The Lancet.

SARS-CoV-2 and anti-COVID-19 drugs activate Kaposi sarcoma-associated herpesvirus

A new study published on the preprint server bioRxiv* aimed to investigate the impacts of COVID-19 on people with various illnesses. Specifically, the researchers at the Rockefeller Cancer Institute, and the University of Arkansas for Medical Sciences wanted to see the effects of COVID-19 on patients with cancer and other infectious diseases.

Antibiotic treatment is as good as appendectomy for a majority of adults with appendicitis

Seven of 10 adults with appendicitis can safely avoid surgical removal of their appendix (appendectomy) for at least several months by receiving a course of antibiotics, according to early results of a U.S. study that is the largest to compare use of these drugs alone versus an operation for appendicitis treatment.

Study shows why antiretroviral therapy does not work in certain HIV patients

Increasingly, UPMC's chief of infectious diseases - a well-regarded expert in HIV/AIDS - is contacted by a perplexed physician describing a patient with HIV who insists they are adhering to the daily medication regimen meant to keep the virus in check, but testing says otherwise.

Chronic illnesses promote active SARS-CoV-2 infection via suppressed mucosal immunity

A recent paper published in the preprint server medRxiv in September 2020 discusses the “clinically relevant variation in the expression of COVID-19-related genes”, which is associated with the host and environmental factors, as well as host genetic factors.

Thiopurines could help stop viral replication in human coronaviruses

Researchers from the Department of Microbiology & Immunology, Dalhousie University, University of Calgary, and Department of Biochemistry and Molecular Biology, University of British Columbia, Canada, worked with human coronaviruses in cell cultures to look for drugs that might prevent accumulation and replication of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).

Cats and dogs are low risk for SARS-CoV-2 transmission to humans

Researchers from the College of Veterinary Medicine and Biomedical Sciences, Colorado State University studied the possible transmission of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) among domestic cats and dogs.

Production of six monoclonal antibodies against SARS-CoV-2 spike protein

Youjia Guo et al. in a recent bioRxiv preprint paper demonstrate the robust performance of mouse anti-SARS-CoV-2 spike monoclonal antibodies in immunoassays, including western blotting, ELISA, immunofluorescence, and immunoprecipitation and also neutralizing activity in vitro against SARS-CoV-2 infection.

Development of a coarse-grained model of SARS-CoV-2 virion

A team of scientists of the University of Chicago and the University of California San Diego has developed a coarse-grained (CG) model of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) virion. The model can be used as a valuable resource to perform multiscale simulations of the SARS-CoV-2 virion. The study is currently available on the bioRxiv* preprint server.
