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.

Clinical trial begins to evaluate SENSE device’s ability to monitor intracranial hemorrhage

Sense Diagnostics, a medical technology company focused on improving outcomes for stroke and brain injury patients, announced the initiation of a multicenter pivotal trial to evaluate the safety and efficacy of a non-invasive brain scanner to monitor intracranial hemorrhage in an acute hospital setting.

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 proves that postural orthostatic tachycardia syndrome may be an autoimmune disorder

The symptoms of postural orthostatic tachycardia syndrome, or POTS, can be as varied as they are confounding. There can be fatigue, pain, bleeding disorders and anxiety. Heart palpitations and lightheadedness are common.

Study highlights the importance of ensuring newborns have close contact with parents during COVID-19

New research from WHO and partners shows that the COVID-19 pandemic is severely affecting the quality of care given to small and sick newborns, resulting in unnecessary suffering and deaths.

Study: Slow walkers have higher risk of contracting severe COVID-19

SLOW walkers are almost four times more likely to die from COVID-19, and have over twice the risk of contracting a severe version of the virus, according to a team of researchers from the National Institute for Health Research (NIHR) Leicester Biomedical Research Centre led by Professor Tom Yates at the University of Leicester.

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.

High-strength nicotine e-cigarettes can help adults with schizophrenia quit smoking

A new study in Nicotine & Tobacco Research, published by Oxford University Press, finds that the use of high-strength nicotine e-cigarettes can help adults with schizophrenia spectrum disorders quit smoking.

New approach may lead to novel treatments for renal fibrosis

Ageing is a common factor in many diseases. So, what if it were possible to treat them by acting on the causes of ageing or, more specifically, by acting on the shortening of telomeres, the structures that protect chromosomes?

Researchers identify a possible cause of functional neurological disorder

Researchers believe they may have discovered a possible cause of a mystery condition that can leave sufferers suddenly unable to walk, talk or see.

Study suggests daily testing instead of self-isolation for contacts of SARS-CoV-2 cases

In the study, which appeared in the pre-print server medRxiv*, the researchers aimed to evaluate the acceptability and engagement with the daily testing as an alternative to self-isolation. They found that daily testing is acceptable and may help promote adherence to self-isolation.

An increase in the risk of clinical sequelae after SARS-CoV-2 infection

A new piece of research, published on the medRxiv preprint server, focused on the role of factors such as gender, age, hospitalization, etc., in understanding the risks of clinical sequelae in the post-acute phase of COVID-19, in adults aged between 18 and 65 years.

Study of post-acute sequelae of SARS-CoV-2 infection shows persistent symptoms 8 months

Researchers from the US recently studied the prevalence of PASC in a well-characterized cohort of patients to gain insights into the period following acute SARS-CoV-2 infection. The research is posted online to the preprint server medRxiv.
