Medical Xpress / Heart capillaries may build natural bypasses for blood flow after heart attacks
The heart powers a busy highway of arteries and vessels, providing a constant to-and-fro passage for blood. During a heart attack, this passage becomes blocked, usually when a blood clot forms on plaque in a coronary artery ...
Medical Xpress / Internal body awareness does not predict mental health, study finds
The human brain continuously receives information from inside the body that helps detect physical needs and emotional states, such as a racing heartbeat, shortness of breath, hunger, thirst, pain and body temperature. Its ...
Medical Xpress / New mRNA immunotherapy eliminates pancreatic tumors in mice
Inspired by the work of the RNA Therapeutics Institute at UMass Chan Medical School and the development of the COVID vaccine, Marcus Ruscetti, Ph.D., and Chaitanya Naimesh Parikh, Ph.D. '26, have developed an immunotherapy ...
Medical Xpress / First-in-human pilot trial improves stem cell collection and delivery for sickle cell gene therapy
Patients with sickle cell disease are often hesitant to undergo transformative gene therapy—the current lengthy process requires multiple hospital visits to collect enough stem cells. Researchers from Boston Children's Hospital ...
Medical Xpress / 'Supportive' brain cells may actively drive cognitive decline
Brain cells that produce the protective coating around nerve fibers can become dysfunctional with age and may actively contribute to cognitive decline, according to new research.
Medical Xpress / Loneliness rewires the brain to drive alcohol use, preclinical study finds
Loneliness can reprogram the brain in ways that increase alcohol consumption, according to a new preclinical study led by Northwestern University and the Salk Institute for Biological Studies. The scientists identified, for ...
Medical Xpress / 'Teacher cells' coated with tumor fragments train T cells to attack cancer in lab tests
The immune system possesses legions of T cells that, if primed, could hunt down and destroy tumors. Now, a UC San Francisco team has invented a way to do this by combining immune cells grown in the lab with samples from a ...
Medical Xpress / First evidence of mirror-like activity found in individual human neurons
In the early 1990s, researchers studying nonhuman primates discovered a population of brain cells they called "mirror neurons." These specialized brain cells fired when the animal performed an action and also when the animal ...
Medical Xpress / Why glaucoma risk may be missed by day: Nighttime eye-pressure pathway revealed
Glaucoma is an eye disease that causes progressive damage to the optic nerve, leading to vision loss. One major risk factor is an increase in intraocular pressure (IOP), or pressure inside the eye. This pressure fluctuates ...
Medical Xpress / At least 1 in 4 former NFL players who died between 2016 and 2021 had CTE, study finds
In a new study from Mass General Brigham, Boston University (BU), and the Concussion & CTE Foundation, researchers found evidence that at least one in four former NFL players who died between 2016 and 2021 had chronic traumatic ...
Medical Xpress / AI helps identify regulatory hub for aging in hematopoietic stem cells
Stem cells possess the unique ability to self-renew and transform into different types of cells. For example, rare hematopoietic stem cells found in bone marrow can become any type of blood cell. Throughout life, they can ...
Medical Xpress / Blocking cellular 'freecycling' may slow bone marrow scarring in myelofibrosis
In a new study published in Nature Communications, Boston Children's Hospital researchers identified a new target responsible for scar formation in the bone marrow of patients with a type of blood cancer known as myelofibrosis. ...
