Scientists design experimental gut-brain system in a lab dish

Research into what is known as the gut-brain axis continues to reveal how the brain and gut influence each other's health and well-being. Now researchers are endeavoring to learn more about gut-brain discourse using a model system built in a lab dish.

Anesthesia and sleep have surprisingly similar effects on brain activity, finds study

What happens in the brain when our conscious awareness fades during general anesthesia and normal sleep? Finnish scientists studied this question with novel experimental designs and functional brain imaging.

Brain scans predict posttraumatic stress disorder following mild TBI

Posttraumatic stress disorder (PTSD) is a complex psychiatric disorder brought on by physical and/or psychological trauma. How its symptoms, including anxiety, depression and cognitive disturbances arise remains incompletely understood and unpredictable.

Study offers explanation for silent hypoxemia in COVID-19 patients

One of the physiopathological characteristics of COVID-19 that has most baffled the scientific and medical community is what is known as "silent hypoxemia" or "happy hypoxia".

Stopping RAS inhibitors linked to risk of adverse outcomes in patients with chronic kidney disease

Small studies have suggested that a group of medications called RAS inhibitors may be harmful in persons with advanced chronic kidney disease, and physicians therefore often stop the treatment in such patients.

Neurologists say there is no medical justification for neck restraints in policing

Some police departments in the United States continue to teach officers that neck restraints are a safe method for controlling agitated or aggressive people, but that's a dangerous myth, according to a Viewpoint written by three neurologists at Massachusetts General Hospital (MGH) in JAMA Neurology.

Researchers discover how chromosomal instability allows cancer cells to avoid immune defenses

Cancer cells are known for spreading genetic chaos. As cancer cells divide, DNA segments and even whole chromosomes can be duplicated, mutated, or lost altogether. This is called chromosomal instability, and scientists at Memorial Sloan Kettering have learned that it is associated with cancer's aggressiveness.

Scientists identify distinct sub-types of angiosarcomas to allow for targeted treatment

A new study led by clinician-scientists from the National Cancer Centre Singapore, with collaborators from research institutions worldwide, has found that angiosarcomas have unique genomic and immune profiles which allow them to be classified into three different subtypes.

New studies uncover link between vaping and mental fog

Two new studies from the University of Rochester Medical Center have uncovered an association between vaping and mental fog. Both adults and kids who vape were more likely to report difficulty concentrating, remembering, or making decisions than their non-vaping, non-smoking peers.

The evolving role of platelet-rich plasma in cosmetic procedures

Platelet-rich plasma (PRP) treatment, which involves injecting a small amount of a patient's own blood to release various growth factors from platelets, continues to increase in popularity.

Scientists decode music-evoked emotions in the brain

Researchers at the University of Turku have discovered what type of neural mechanisms are the basis for emotional responses to music.

Severity of COVID-19 correlates with the ratio of antibodies targeting crucial viral protein

COVID-19 antibodies preferentially target a different part of the virus in mild cases of COVID-19 than they do in severe cases, and wane significantly within several months of infection, according to a new study by researchers at Stanford Medicine.

SARS-CoV-2 spike-antibody binding strength and hydrogen bond numbers are temperature dependent, study finds

A new preprint on the bioRxiv* server describes the interactions between the binding spike protein of the SARS-CoV-2 virus with the antibodies. Earlier studies have addressed the similarity in the 3D structures of the spike protein in the two SARS viruses as seen on cryo-EM.

Animal study suggests palmitoylation inhibitor reduces virulence of SARS-CoV-2

A new study preprint on the bioRxiv* server demonstrates the ability of a fatty acid synthase inhibitor to improve the survival of mice infected with murine hepatitis virus. In so doing, it adds to the sum of knowledge about the relationship of SARS-CoV-2 with cholesterol metabolism in the host cell.

Anti-SARS-CoV-2 NTD-directed antibodies are protective against lethal infection

As the world struggles to contain the severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), responsible for over 1.6 million deaths and 76 million infections globally, researchers are trying to pin down the determinants of lethality, of infectivity and of protection. Such data would help contain its spread and develop preventive and therapeutic antivirals and vaccines. A new preprint that appeared recently on the bioRxiv* server describes the high degree of protection afforded by antibodies that target the N-terminal domain (NTD) of the virus.

Immunologic modeling of COVID-19 severity and chronicity

In a new study by researchers at Universidad de Costa Rica and other institutions, a bioinformatics approach is used to determine whether Chronic COVID-19 (CC) might have a distinct immunologic signature compared to the mild to moderate (MM) or the severe/critical COVID-19.

Loss of taste and smell may be most reliable COVID-19 symptoms for digital surveillance

A team of researchers from various institutions in London, Israel, and the USA recently tested the existence of consistent links between COVID-19 symptoms and SARS-CoV-2 test status in 3 national surveillance platforms.

Mental disorders highly prevalent during coronavirus pandemics

Researchers in the United States have conducted an analysis showing the high prevalence of mental disorders across populations impacted by coronavirus pandemics.

Higher BMI linked to increased risk of SARS-CoV-2 infection

Researchers at the University of Miami Miller School of Medicine, USA, revealed that the spike-specific immunoglobulin G antibodies in obese people are negatively associated with body mass index (BMI) and serum levels of proinflammatory and metabolic markers of pulmonary inflammation.

How has the COVID19 pandemic affected the well-being of pregnant women?

A new study by researchers at the Department of Women and Children’s Health at Uppsala University, Sweden, aimed to determine the effects of COVID-19 on pregnant women's mental health and well-being.
