Propylparaben exposure during pregnancy may lessen protection against breast cancer

Low doses of propylparaben - a chemical preservative found in food, drugs and cosmetics - can alter pregnancy-related changes in the breast in ways that may lessen the protection against breast cancer that pregnancy hormones normally convey, according to University of Massachusetts Amherst research.

New study aims to develop alternative treatment for posterior eye diseases

Getting poked in the eye with a sharp object is a cringeworthy thought. However, many patients with posterior eye diseases -- back of the eye diseases such as macular degeneration or diabetic retinopathy -- undergo eye injections through the wall of the eye as a medical treatment on a regular basis.

UW–Madison researchers find a new way for accurate measurement of consciousness

Millions of people are administered general anesthesia each year in the United States alone, but it's not always easy to tell whether they are actually unconscious.

URI researchers develop new, saliva-based COVID-19 test

Researchers at the University of Rhode Island have developed a new COVID-19 test that will soon be put into use across its campuses as a screening and surveillance tool for the COVID-19 virus.

Combination therapy may reduce influenza-associated morbidity and mortality

A significant proportion of hospitalized patients with influenza develop complications of acute respiratory distress syndrome, driven by virus-induced cytopathic effects as well as exaggerated host immune response.

Consumption of added sugar boosts fat production in the liver

Too much sugar is unhealthy – that we know, but it’s not just down to the many calories. Even moderate amounts of added fructose and sucrose double the body’s own fat production in the liver, researchers from the University of Zurich have shown.

ALSF announces grant award recipients of Crazy 8 Initiative in pediatric oncology

Alex's Lemonade Stand Foundation, a nonprofit foundation devoted to finding cures for all children with cancer, announces grant award recipients of their Crazy 8 Initiative.

SARS-CoV-2 Brazilian variant may potentially escape T cell-mediated host immune responses

A team of scientists from Brazil recently explored the abilities of the UK, South African, and Brazilian variants of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) to evade host CD8+ T cell responses induced by natural infection or vaccination. The findings reveal reduced antigenic coverage for the P.2 Brazilian lineage, indicating its ability to evade SARS-CoV-2-induced T cell responses.

Ferret study shows SARS-CoV-2 airborne transmission dynamics

A team of researchers led by Sander Herfst from Erasmus University Medical Center in The Netherlands suggests severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) could spread through the air at a one-meter distance and cause infection in a new ferret model study.

SARS-CoV-2 in wastewater may pose risks to marine mammals

Endangered marine mammals — seals, dolphins, whales, and otters — are almost as vulnerable as humans in becoming infected from severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Researchers from the Dalhousie University in Canada published a study in Science of The Total Environment that found human wastewater as a potential mode of coronavirus transmission to animals.

Cross-national study associates low vitamin D levels with higher COVID-19-related mortality

A new study by an international team of researchers – from New York University, Abu Dhabi, the Ludwig-Maximilians-Universität, München, and Barts Cancer Institute, London – showed that there are lower COVID-19 mortality rates in countries with the most insufficient annual sun exposure, but highest mean 25-hydroxyvitamin D (25(OH)D) or vitamin D (25)-HD levels.

Sex differences play roles in how patients respond to brain diseases

Men and women are impacted differently by brain diseases, like Alzheimer's disease and Parkinson's disease. Researchers are urging their colleagues to remember those differences when researching treatments and cures.

Study explores how SARS-CoV-2 mutations produce antibody resistance and enhanced transmissibility

An interesting new study deals with the effects of the natural mutations in the spike antigen of the SARS-CoV-2, the pathogen that is responsible for the ongoing coronavirus disease pandemic.

Backtracking occurs within SARS-CoV-2 replication-transcription complex

Researchers continue to achieve a better understanding of SARS-CoV-2, the virus behind the ongoing COVID-19 pandemic. One such effort has been reported in a new preprint on the bioRxiv server, dealing with the phenomenon of backtracking.

The role of RNA capping of SARS-CoV-2 in immunity evasion

The SARS-CoV-2 pathogen successfully uses multiple immune evasion mechanisms to achieve infection within its host. An intriguing new study describes one such process, which may help develop drugs to counteract the virus more effectively.

New study tests how mutations in SARS-CoV-2 affect antibody neutralization

Using pseudoviruses with single amino acid substitutions, researchers found that mutations in SARS-CoV-2 reduce monoclonal antibody neutralization differently. However, convalescent sera samples did not lose neutralization potency many and were also effective against the B.1.1.7 (UK-derived) strain.

Engineered mouse Intestine Chip platform can help study host-microbiome interactions

Trillions of commensal microbes live on the mucosal and epidermal surfaces of the body and it is firmly established that this microbiome affects its host's tolerance and sensitivity of the host to a variety of pathogens.
