Study suggests new strategy for treating arrhythmogenic cardiomyopathy

University of Utah Health scientists have corrected abnormal heart rhythms in mice by restoring healthy levels of a protein that heart cells need to establish connections with one another.

Study reveals the cellular composition and circuit organization of the locus coeruleus

A small nucleus in the brainstem called locus coeruleus (literally the "blue spot,") is the primary source of a major neuromodulator, norepinephrine (NE), an important mediator of the 'fight or flight' response in animals. However, very little is known about the local connections of this small albeit critically important group of neurons.

High doses of sucralose limit T cell proliferation and differentiation

Scientists at the Francis Crick Institute have found that high consumption of a common artificial sweetener, sucralose, lowers activation of T-cells, an important component of the immune system, in mice.

High blood caffeine levels lower body fat and the long-term risks of type 2 diabetes, study finds

A high blood caffeine level might curb the amount of body fat a person carries and their risk of type 2 diabetes, suggests research published in the open access journal BMJ Medicine.

Novel technology easily detects active Mycobacterium tuberculosis infection antibodies

A team of faculty from Wayne State University has discovered new technology that will quickly and easily detect active Mycobacterium tuberculosis (TB) infection antibodies.

Analyzing the antimicrobial resistance profile of the main agent of urinary tract infections

The human intestine is an environment inhabited by many bacteria and other microorganisms collectively known as the gut microbiome, gut microbiota or intestinal flora. In most people, it contributes to wellness. A healthy gut indicates a stronger immune system, improved metabolism, and a healthy brain and heart, among other functions.

Rest boosts the immune system of migratory birds, study finds

Exercising too much and not getting enough rest is bad for your health. A new study from Lund University in Sweden shows that the same is true for migratory birds. They need to rest not only to renew their energy levels but also in order to boost their immune system.

Monitoring the development and maturation of cardiomyocytes using tissue-embedded devices

Research in animal models has demonstrated that stem-cell derived heart tissues have promising potential for therapeutic applications to treat cardiac disease. But before such therapies are viable and safe for use in humans, scientists must first precisely understand on the cellular and molecular levels which factors are necessary for implanted stem-cell derived heart cells to properly grow and integrate in three dimensions within surrounding tissue.

Scientists reveal mechanisms behind oxygen toxicity

When it comes to oxygen, you can have too much of a good thing. Breathing air that contains higher levels of oxygen than the usual 21 percent found in Earth's atmosphere can cause organ damage, seizures, and even death in people and animals, particularly if it's in excess of the body's oxygen needs. Until now, however, scientists have mostly speculated about the mechanisms behind this phenomenon, known as oxygen toxicity, or hyperoxia.

AI tool can accurately identify normal and abnormal chest X-rays in a clinical setting

An artificial intelligence tool can accurately identify normal and abnormal chest X-rays in a clinical setting, according to a study published in Radiology, a journal of the Radiological Society of North America.

New insights into the underlying mechanism that causes arrhythmogenic cardiomyopathy

Researchers from the group of Eva van Rooij in collaboration with the UMC Utrecht identified a new mutation that leads to the cardiac disease arrhythmogenic cardiomyopathy (ACM).

Researchers provide an entirely new perspective on tissue oxygenation

Cardiovascular medicine, hematology and pulmonary medicine may soon have the first-ever therapies to correct poor tissue oxygenation, a key driver of disease in millions, including peripheral artery disease, sickle cell disease, heart failure, stroke, emphysema and many others.

Cell therapy trial promises long-term improvement for patients with chronic heart failure

Physician-scientists at The Texas Heart Institute announced today the results of the largest cell therapy trial to date in patients with chronic heart failure due to low ejection fraction.

Study: Oral verapamil improves the pancreas' insulin secretion in children with newly-diagnosed TID

Published in JAMA, a University of Minnesota led study shows that verapamil, a drug commonly used to treat high blood pressure and heart conditions, can have a beneficial effect on the pancreas in children with newly-diagnosed type 1 diabetes (T1D).

Researchers tease apart the molecular components involved in abdominal aneurysms

When the artery that supplies the stomach and the liver forms a bulge that ruptures, this medical emergency results in the deaths of 50 percent of patients before they reach the hospital.

Deep-learning approach to achieve faster and high-resolution photoacoustic computed tomography

It takes a few moments for the sound of thunder to reach our ears after a flash of lightning. This phenomenon is due to the photoacoustic (PA) effect where materials near the lightning instantly expand as the optical energy of the lightning is absorbed and converted into thermal energy.

Robust method for induced pluripotent stem cell culture

Different types of cells, such as the heart, liver, blood, and sperm cells, have characteristics that help them perform their specific functions in the body. In general, those traits are hard-wired. A heart cell will not randomly transform into a liver cell if not stimulated.

MIT engineers develop new procedure to 3D print a soft, flexible replica of patient's heart

No two hearts beat alike. The size and shape of the the heart can vary from one person to the next. These differences can be particularly pronounced for people living with heart disease, as their hearts and major vessels work harder to overcome any compromised function.
