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

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.

New findings could help better understand the mechanisms underlying severe malaria

The levels of small molecules called microRNAs (miRNAs) circulating in blood could help identify early on children with life-threatening forms of malaria, according to a study led by the Barcelona Institute for Global Health, an institution supported by "la Caixa" Foundation, in collaboration with the Manhiça Health Research Center (CISM) in Mozambique.

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

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.

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

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.

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

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

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?

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.

Change in evidence-based guidelines for vasectomy may reduce number of follow-up tests

A change in evidence-based guidelines for vasectomy may have led to a reduction in the number of follow-up tests to confirm the procedure was successful, reports a study in Urology Practice®, an Official Journal of the American Urological Association (AUA). The journal is published in the Lippincott portfolio by Wolters Kluwer.

Scientists identify bacteria-based approach against cancer

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

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.

Study shows how neurons can become a target of SARS-CoV-2 infection

Using both mouse and human brain tissue, researchers at Yale School of Medicine have discovered that SARS-CoV-2 can directly infect the central nervous system and have begun to unravel some of the virus's effects on brain cells.

Researchers discover a new approach to inhibit intrahepatic cholangiocarcinoma

Reprogramming the rich connective tissue microenvironment of a liver cancer known as intrahepatic cholangiocarcinoma (ICC) inhibits its progression and resistance to standard chemotherapy in animal models, researchers from Massachusetts General Hospital have found.

Study investigates the metabolites involved in growth and spread of melanoma

The first step in treating cancer is understanding how it starts, grows and spreads throughout the body. A relatively new cancer research approach is the study of metabolites, the products of different steps in cancer cell metabolism, and how those substances interact.
