Wearable heart monitors and deep learning can provide early warning of SARS-CoV-2 infection

Tue, 01/12/2021 - 11:26
A recent study, appearing as a preprint on the medRxiv* server, reveals the possibility of early prediction of SARS-CoV-2 infection using data on the resting heart rate in the presymptomatic period.

Researchers identify shorter form of ACE2 that lacks SARS-CoV-2 binding site

Tue, 01/12/2021 - 11:18
A shadow over the promising inhaled interferon beta COVID-19 therapy has been cleared with the discovery that although it appears to increase levels of ACE2 protein - coronavirus' key entry point into nose and lung cells - it predominantly increases levels of a short version of that protein, which the virus cannot bind to.

ARID1A gene in ovarian cancer plays a role in the regulation of metabolism

Tue, 01/12/2021 - 11:16
Mutations that inactivate the ARID1A gene in ovarian cancer increase utilization of the glutamine amino acid making cancer cells dependent on glutamine metabolism, according to a study by The Wistar Institute published online in Nature Cancer.

Study shows COVID-19 pneumonia is different from typical pneumonia

Tue, 01/12/2021 - 11:14
Bacteria or viruses like influenza that cause pneumonia can spread across large regions of the lung over the course of hours. In the modern intensive care unit, these bacteria or viruses are usually controlled either by antibiotics or by the body's immune system within the first few days of the illness.

Researchers study the behavior of regulatory T cells to understand periodontal disease

Tue, 01/12/2021 - 10:58
In diseases characterized by bone loss -such as periodontitis, rheumatoid arthritis, and osteoporosis- there is a lot that scientists still don't understand. What is the role of the immune response in the process? What happens to the regulatory mechanisms that protect bone?

Discovery of SARS-CoV-2 neutralizing antibodies from a naïve human Ab library

Tue, 01/12/2021 - 10:53
Now, a new preprint research paper published on the bioRxiv server shows how closely the antibodies formed in exposed humans resemble the germline antibody molecules. This could lead to the development of novel therapeutics to counter the pandemic.

Study could help develop new oral drugs for treating muscular dystrophy, heart failure

Tue, 01/12/2021 - 10:51
Cell-derived exosomes are effective in treating disease when mixed with the dominant protein in breast milk and given orally, a new Smidt Heart Institute study of laboratory mice shows.

Researchers identify a new link between seizures and connexin 36 deficiency

Tue, 01/12/2021 - 10:47
For the brain to learn, retain memories, process sensory information, and coordinate body movements, its groups of nerve cells must generate coordinated electrical signals. Disorder in synchronous firing can impair these processes and, in extreme cases, lead to seizures and epilepsy.

Patient with hypertension or cardiovascular diseases experienced critical disease progression with COVID-19

Tue, 01/12/2021 - 10:11
COVID-19 patients who also suffer from high blood pressure are more likely to fall severely ill with the disease, which also leaves them at greater risk of death.

COVID-19 taking a disproportionate toll on female healthcare workers

Tue, 01/12/2021 - 10:00
Women in the healthcare workforce seem to be suffering stress and burnout in the current pandemic situation, disproportionately when compared to men, suggests a new preprint research paper published on the medRxiv server.

Mosaic mutations during embryonic development can cause autism spectrum disorder

Tue, 01/12/2021 - 09:58
Two studies in today's Nature Neuroscience, led by researchers at Boston Children's Hospital, Brigham and Women's Hospital (BWH), and Harvard Medical School (HMS), implicate mosaic mutations arising during embryonic development as a cause of autism spectrum disorder (ASD). The findings open new areas for exploring the genetics of ASD and could eventually inform diagnostic testing.

SARS-CoV-2 exposure in England could be double reported seroprevalence

Tue, 01/12/2021 - 09:38
A new study that recently appeared on the preprint server medRxiv* makes use of a combined method to estimate population exposure to the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), taking into account the fact that patients who recover from the infection often do not have circulating antibodies against the virus.

The mystery of Giglio island’s resistance to COVID-19

Tue, 01/12/2021 - 09:18
An intriguing new study explores the mechanisms by which an Italian island called Giglio remained resistant to coronavirus disease 2019 (COVID-19) even after much exposure.

Study supports continuing phase 3 trials of Ad26.COV2.S SARS-CoV-2 vaccine

Tue, 01/12/2021 - 08:06
An international team of researchers has provided further evidence to confirm the immunogenicity and efficacy of a recombinant adenovirus vaccine currently being tested in phase 3 trials for its ability to protect against infection with severe acute respiratory coronavirus 2 (SARS-CoV-2) – the agent that causes coronavirus disease 2019 (COVID-19).

UMass Lowell researcher receives NIH support to develop therapies for young people with TBIs

Tue, 01/12/2021 - 07:51
A UMass Lowell researcher developing innovative therapies for injured children and teens has received more than $700,000 from the National Institutes of Health to support that work.

Study: Telehealth use jumped sharply during the first months of pandemic shutdown

Tue, 01/12/2021 - 07:47
Use of telehealth jumped sharply during the first months of the coronavirus pandemic shutdown, with the approach being used more often for behavioral health services than for medical care, according to a new RAND Corporation study.

Extract of medicinal plant Artemisia annua interferes with replication of SARS-CoV-2 in vitro

Tue, 01/12/2021 - 07:43
Researchers in the United States have shown that extracts of an aromatic herb called Artemisia annua inhibit the replication of severe acute respiratory coronavirus (SARS-CoV-2) – the agent responsible for the current coronavirus disease 2019 (COVID-19) pandemic.

Scientists receive $3.4 million to study care options for patients with chest pain due to anxiety

Tue, 01/12/2021 - 07:39
Indiana University School of Medicine and Regenstrief Institute research scientists have received a $3.4 million award from the Patient-Centered Outcomes Research Institute to investigate the best care options for the 40 percent of people who go to the hospital emergency department with chest pain that is determined to be caused by anxiety rather than a cardiac event.

Study aims to halt further isolation of people aging with HIV during COVID-19 pandemic

Tue, 01/12/2021 - 07:31
The School of Medicine at the University of California, Riverside, has received a grant aimed at halting further isolation of people aging with HIV during the COVID-19 pandemic.
