Two out of five U.S. adults missed medical care in the early phase of pandemic

Two out of five individuals delayed or missed medical care in the early phase of the pandemic--from March through mid-July 2020--according to a new survey from researchers at the Johns Hopkins Bloomberg School of Public Health.

New SERS-based sensor can detect influenza A viral pathogens with high reproducibility

Respiratory diseases like influenza can spread rapidly and escalate to global health crises. Thus, to control them, simple yet sensitive detection techniques are needed. Surface-enhanced Raman scattering (SERS) is a potential candidate but currently lacks reproducibility.

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.

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.

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?

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.

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.

Differences in hair aging between varying races and ethnicities

While aging is an unavoidable biological process with many influencing factors that results in visible changes to the hair, there is limited literature examining the characteristics of hair aging across the races.

Study finds racial disparities in side-specific biological aging of the colon

The colons of African-Americans and people of European descent age differently, new research reveals, helping explain racial disparities in colorectal cancer - the cancer that killed beloved "Black Panther" star Chadwick Boseman at only 43.

Nicotine promotes breast cancer lung metastasis, finds study

Breast cancer is the second most common cancer among women in the United States, and cigarette smoking is associated with a higher incidence of breast cancer spread, or metastasis, lowering the survival rate by 33% at diagnosis.

New SARS-CoV-2 strain detected in Southern California, USA

By analyzing throat and nose swabs from patients in Southern California, researchers detected a new SARS-CoV-2 strain with mutations in the spike protein. This major finding may explain a surge in the number of cases in the region.

High factor V levels linked to lymphopenia and weakened immunity in severe COVID-19

A new study suggests that factor V, a coagulation factor, is upregulated in a range of white blood cells in severe COVID-19. This increase is linked to the observed coagulopathy, lymphopenia and suppression of adaptive immunity in such patients.
