Study identifies features of potent SARS-CoV-2 neutralizing antibodies

Thu, 01/14/2021 - 04:20
Researchers at Columbia University have provided important insights into features of viral binding and recognition within a class of potent neutralizing antibodies against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) – the agent that causes coronavirus disease 2019 (COVID-19).

How has the UK-derived SARS-CoV-2 mutant strain spread internationally?

Thu, 01/14/2021 - 00:19
Researchers analyzed Facebook-based mobility data and found that travelers from UK may have spread the new SARS-CoV-2 strain that originated in the UK to at least 16 countries by the beginning of December 2020.

Moderna to develop three new mRNA-based vaccines against HIV, influenza, and the Nipah virus

Wed, 01/13/2021 - 23:50
Morderna has announced plans to develop a range of new mRNA-based vaccines against other viruses, including the influenza virus, human immunodeficiency virus (HIV), and the Nipah virus.

COVID-19 survivors show persistent symptoms six months after recovery, study finds

Wed, 01/13/2021 - 23:25
A team of researchers conduct a large study exploring the persistence of COVID-19 symptoms in recovered patients.

Researchers map genetic changes that may have facilitated SARS-CoV-2’s jump from bats to humans

Wed, 01/13/2021 - 22:59
Researchers from the University of Cambridge and the Pirbright Institute in the UK have identified key genetic changes in SARS-CoV-2 that may be responsible for the virus’s jump from bats to humans. The team also determined which animals contain cellular receptors that allow the virus to enter cells more effectively, zoning in on potential animals that acted as an intermediary host in facilitating SARS-CoV-2’s zoonosis.

New N501 SARS-CoV-2 mutation may have been circulating in Italy since August 2020

Wed, 01/13/2021 - 21:30
A recent study shows that mutated SARS-CoV-2 strains with a substitution at position 501 might have circulated unnoticed even before the end of September 2020, when the rapid emergence of B.1.1.7 lineage (carrying the N501Y mutation) was initially reported.

Study shows faster uptake of chemicals in people with a genetically weakened skin barrier

Wed, 01/13/2021 - 18:49
The ability of our skin to protect us from chemicals is something we inherit. Some people are less well-protected which could imply an increased risk of being afflicted by skin disease or cancer.

People who take walks in forests or greenspaces may have higher stress coping abilities

Wed, 01/13/2021 - 18:36
Work causes so much stress that it's become a global public health issue. Stress's impact on mental and physical health can also hurt productivity and result in economic loss. A new study now finds that working people who regularly take walks in forests or greenspaces may have higher stress-coping abilities.

New UK-derived SARS-CoV-2 variant does not affect neutralizing antibodies efficiency, study says

Wed, 01/13/2021 - 18:34
A team of scientists conducted structural analysis of a newly emerged UK variant of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). They present evidence that suggests that while the new variant has increased infectivity it is not resistant to neutralizing antibodies.

Study shows distancing and mandatory masks can prevent 87% of campus COVID-19 infections

Wed, 01/13/2021 - 18:33
The combined effectiveness of three COVID-prevention strategies on college campuses--mask-wearing, social distancing, and routine testing--are as effective in preventing coronavirus infections as the Pfizer and Moderna vaccines approved by the U.S. Food and Drug Administration (FDA), according to a new study co-authored by a Case Western Reserve University researcher.

College campuses at risk of becoming COVID-19 superspreaders, study shows

Wed, 01/13/2021 - 18:24
College campuses are at risk of becoming COVID-19 superspreaders for their entire county, according to a new vast study which shows the striking danger of the first two weeks of school in particular.

Researchers use urine test to identify and verify a patient's type of asthma

Wed, 01/13/2021 - 18:17
In a new study, researchers at Karolinska Institutet in Sweden have used a urine test to identify and verify a patient's type of asthma.

Recurring glioblastomas with very few mutations are far more vulnerable to immunotherapies

Wed, 01/13/2021 - 18:17
Glioblastoma brain tumors are especially perplexing. Inevitably lethal, the tumors occasionally respond to new immunotherapies after they've grown back, enabling up to 20% of patients to live well beyond predicted survival times.

Could fenofibrate be an effective antiviral against SARS-CoV-2?

Wed, 01/13/2021 - 17:20
The resurgence of COVID-19 pandemic, caused by the SARS-CoV-2, has led to renewed efforts to find effective antivirals, both newly developed or repurposed drugs. A study reports the efficacy of the cholesterol-reducing drug fenofibrate in reducing infection rates of SARS-CoV-2 in cultured cells.

Researchers assess medical practice patterns of primary care physicians

Wed, 01/13/2021 - 12:34
Harmful medical practices, like inappropriate prescribing of opioids and racial and income-based discrimination in clinical settings, can vary across medical practices and individuals.

New technology could protect against different coronavirus variants

Wed, 01/13/2021 - 12:06
The SARS-CoV-2 virus that is causing the COVID-19 pandemic is just one of many different viruses in the coronavirus family.

Scientists identify bacteria-based approach against cancer

Wed, 01/13/2021 - 12:02
The body's immune system is the first line of defense against infections like bacteria, viruses or cancers. Some cancers, however, have developed the art of molecular deception to avoid destruction by the body's immune system.

Researchers develop novel antibody fragments against SARS coronavirus-2

Wed, 01/13/2021 - 11:19
An international research team led by the University of Bonn (Germany) has identified and further developed novel antibody fragments against the SARS coronavirus-2. These "nanobodies" are much smaller than the classic antibodies used to treat US President Donald Trump, for example.

New publication describes DiosCURE’s multivalent single-chain antibodies to inactivate SARS-CoV-2

Wed, 01/13/2021 - 11:12
DiosCURE SE announced a publication in Science describing its core technology of multivalent single-chain antibodies with a unique molecular mode-of-action to inactivate SARS-CoV-2 virions. An international team led by scientists at the University of Bonn developed and characterized the lead candidates, which are exclusively licensed by DiosCURE.
