$Metabolic-immune interaction appears to be the cause of heart failure with preserved ejection fraction$

Metabolic-immune interaction appears to be the cause of heart failure with preserved ejection fraction

The dominant form of heart failure worldwide appears to be caused by a strong, bidirectional interaction between the body's response to metabolic stress and the immune system, according to a review article written by UT Southwestern researchers and colleagues.

Study uncovers a gene that strongly associates with breast cancer patient's treatment outcomes

A multidisciplinary team of researchers from Roswell Park Comprehensive Cancer Center and Kaiser Permanente Northern California have identified the first pharmacogenomic marker for anthracyclines and HER2-targeting drugs, two commonly used breast cancer chemotherapies.

SARS-CoV-2 is evolving adaptively in multiple regions of the genome

Scientists from the United States have recently assessed the evolutionary success of mutations accumulated across severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) genome. They have observed that the positively-selected mutations in the viral spike S1 subunit are primarily responsible for adaptive evolution. This indicates that the virus may undergo antigenic drift.

Stress hormone cortisol decreases altruistic behavior in people with high mentalizing ability

The stress hormone cortisol reduces altruistic behavior and alters activity in brain regions linked to social decision making - but only in people who are better at imagining others' mental states, according to new research published in JNeurosci.

Niacin limits Alzheimer's disease progression in animal model

Indiana University School of Medicine researchers found that niacin limits Alzheimer's disease progression when used in models in the lab, a discovery that could potentially pave the way toward therapeutic approaches to the disease.

Origins of Type 2 diabetes differ between males and females, research shows

Over the past four decades, global cases of Type 2 diabetes mellitus have skyrocketed. According to the World Health Organization, the number of people estimated to have the disease jumped from 108 million in 1980 to 422 million in 2014, with the fastest growth observed in low- and middle-income countries.

Study confirms no preexisting B-cell immunity against SARS-CoV-2 in pre-pandemic samples

A recent study finds that there is no considerable B-cell immunity against SARS-CoV-2 in unexposed healthy individuals.

Recombinant SARS-CoV-2 Delta-Omicron variant identified in the United States

There is likely recombination of genome sequences between the SARS-CoV-2 Delta and Omicron variants in their spike (S) protein.

Researchers aim to study the underlying pathophysiology of diastolic heart failure

Of the estimated five million patients in the U.S. diagnosed with heart failure annually, nearly half will have heart failure with preserved ejection fraction (HFpEF). Also known as diastolic heart failure, HFpEF occurs when the heart's lower left chamber loses its ability to relax and fill up with enough blood in between in each heartbeat.

Sleeping with lights on can be harmful to your health

Acute exposure to artificial light during nighttime sleep can increase heart rate and insulin resistance by activating the sympathetic nervous system.

New nanoparticle-based COVID-19 vaccine platform could target other infectious diseases

Just one dose of a new nanoparticle-based COVID-19 vaccine was enough to produce an immune response in animals on track with vaccines currently in clinical use.

New device based on concert hall acoustics enables noninvasive, ultrasound brain treatments

A team led by engineers at the University of California San Diego has developed a device that is a first step to enabling noninvasive, ultrasound-based therapies for the brain.

Monoclonal antibodies found to prevent lung inflammation in SARS-CoV-2-Omicron-infected mice

Researchers investigated how monoclonal antibodies, S309 and AZD7442, reduced lung infection in mice infected with the SARS-CoV-2 new variant of concern Omicron's BA.1, BA.1.1, and BA.2 sublineages.

Researchers unravel the neural mechanisms underlying familial risk for depression

Children of mothers with clinical depression are at three times greater risk to develop depression themselves than are their low-risk peers. Researchers are working to understand the neural underpinnings of the risk, and some studies have shown altered brain processing of reward in at-risk children as young as 6.
