Mitochondrial mutation linked to elevated diabetes risk in Japanese men

A new study of Type 2 diabetes in Japanese populations has uncovered a previously uncharacterized genetic variant that puts male carriers at greater risk for the disease, as well as the mechanism by which it does so.

Prioritizing older adults for COVID-19 vaccination will save more lives

Vaccinating older adults for COVID-19 first will save substantially more U.S. lives than prioritizing other age groups, and the slower the vaccine rollout and more widespread the virus, the more critical it is to bring them to the front of the line.

New model shows key role of innate immunity in controlling COVID-19 viral load

Since SARS-CoV-2 was identified in December 2019, researchers have worked feverishly to study the novel coronavirus. Although much knowledge has been gained, scientists still have a lot to learn about how SARS-CoV-2 interacts with the human body, and how the immune system fights it.

New data on impact of spike mutations and B117 UK variant on neutralization by mAbs and sera

A recent paper by British and Dutch scientists, currently available on the bioRxiv* preprint server, shows that the neutralizing activity of monoclonal antibodies can be dramatically reduced by mutations of the SARS-CoV-2 spike glycoprotein – unlike polyclonal antibodies generated after natural infection that remain active regardless of any introduced amino acid changes.

SARS-CoV-2 variants appear to arise independently of local transmission

Researchers at the University of Michigan in the United States have cautioned against only using within-host minor genetic variations to resolve the genomic epidemiology of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) – the agent that causes coronavirus disease 2019 (COVID-19).

Pfizer-BioNTech vaccine shows reduced neutralization potential against SARS-CoV-2 B.1.1.7 spike variant

Researchers in the UK have conducted a study assessing the efficacy of the Pfizer-BioNTech COVID-19 vaccine BNT162b2 against the new variant of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) – the agent that causes coronavirus disease 2019 (COVID-19).

Study: Vast majority of U.S. infants may be suffering from gut microbiome deficiency

A new peer-reviewed study reveals that the vast majority of U.S. infants may be suffering from a substantial deficiency in an important bacterium key to breast milk utilization and immune system development, as well as protection against gut pathogens linked to common newborn conditions such as colic and diaper rash.

Positive messages could potentially increase mask usage during the pandemic

Many organizations are looking at effective ways to communicate the importance of wearing a mask, especially as highly transmissible new strains of coronavirus threaten to cause a surge in infections.

Randomized trials could help clarify uncertainties around reopening schools safely

Schools are closing again in response to surging levels of COVID-19 infection, but staging randomised trials when students eventually return could help to clarify uncertainties around when we should send children back to the classroom, according to a new study.

Researchers simulate tailgating to examine the impact of excessive eating and drinking

The NFL playoffs are underway, and fans are finding ways to simulate tailgating during the COVID-19 pandemic. Football watch parties are synonymous with eating fatty foods and drinking alcohol. Have you ever wondered what all of that eating and drinking does to your body?

Older age may offer a buffer against negative feelings brought on by the pandemic

Older adults are managing the stress of the coronavirus pandemic better than younger adults, reporting less depression and anxiety despite also experiencing greater general concern about COVID-19, according to a study recently published by researchers at the UConn School of Nursing.

Dynamic, customized treatment approaches for gastroesophageal cancers may improve survival rates

A phase 2 clinical trial providing personalized treatments based on the genetic profile of metastatic tumors in gastroesophageal cancers has found that using customized treatment approaches, and adapting them over time as tumors become resistant, led to higher rates of survival compared to historical controls.

COVID-19, influenza and suicide are responsible for deaths of ICE detainees

Thirty-five people have died in the custody of U.S. Immigration and Customs Enforcement (ICE) since April 2018, with a seven-fold increase in deaths even as the average daily population decreased by nearly a third between 2019 and 2020, a new USC study shows.

New drug target valid for breast cancer as well as lymphoma

One more piece of the puzzle has fallen into place behind a new drug whose anti-cancer potential was developed at the University of Alberta and is set to begin human trials this year, thanks to newly published research.

SARS-CoV-2 suppresses host innate immunity

SARS-CoV-2, the virus that causes COVID-19, blocks the processes of innate immune activation that normally direct the production and/or signaling of type I interferon (IFN-I) by the infected cell and tissues.

Study identifies nine specific genes associated with breast cancer risk

Breast cancer investigators in the Lambe Institute at NUI Galway have collaborated on a pivotal international study into breast cancer risk which was published in the New England Journal of Medicine today (Wednesday, 20 January).

Abnormal hyperactivation in the brain could be an early biomarker of Alzheimer's disease

Abnormally hyperactive areas in the brain may help better predict the onset of Alzheimer's disease, according to findings of a research team led by Université de Montreal psychology professor Sylvie Belleville, scientific Director of the Institut universitaire de gériatrie de Montréal research centre.
