Strokes lead to irreversible damage to the brain and are one of the most common causes of dependency or death. As the cellular reactions to a cerebral infarction are not yet fully understood, there is a lack of possible approaches to promote the regeneration of damaged nerve tissue in the brain. A new study closes
To diagnose heart conditions including heart attacks and heart rhythm disturbances, clinicians typically rely on 12-lead electrocardiograms (ECGs) -- complex arrangements of electrodes and wires placed around the chest and limbs to detect the heart's electrical activity. But these ECGs require specialized equipment and expertise, and not all clinics have the capability to perform them.

A new small study has revealed the impact of obesity on muscle structure in patients having a form of heart failure called heart failure with a preserved ejection fraction (HFpEF). A new small study led by Johns Hopkins Medicine researchers and published July 25th in the journal Nature Cardiovascular Research has revealed the impact of

A new paper surveying advances in diabetes pathogenesis and treatment explores the complex factors contributing to the onset and progression of the disease, suggesting that an understanding of these dynamics is key to developing targeted interventions to reduce the risk of developing diabetes and managing its complications.

The brain contains many cell types, from the prominent neurons to the lesser-known microglia. The latter are integral to the brain's immune system and play a crucial role as the brain's cleanup crew. A recent study highlights that microglia establish connections with neurons through tunneling nanotubes. The researchers observed that microglia utilize these tubes to
In an important study for understanding how memories are made, cientists show that the flexibility of chromatin -- packaged DNA inside the cell -- plays a crucial role in 'deciding' which neurons are involved in forming a specific memory. When we form a new memory, the brain undergoes physical and functional changes known collectively as
A new mathematical method, validated with experimental animal data, provides a fast, reliable and minimally invasive way of determining how to treat critical blood pressure changes during surgery or intensive care. If patients receiving intensive care or undergoing major surgery develop excessively high or low blood pressures, they could suffer severe organ dysfunction. It's not
New research shows that a certain bug, Alcaligenes faecalis (A. faecalis), can facilitate healing of hard-to-treat wounds among people with diabetes. While there are many studies done on potentially harmful bacteria in wounds, the researchers discovered that A. faecalis, a bacterium found in many types of chronic wounds, actually boosts healing of diabetic wounds. The
Mammals that have evolved more developed brains tend to have a smaller size difference between males and females of that species, according to new research. In many mammal species, the males can be bigger than the females (or vice versa), a trait called sexual size dimorphism (SSD). For example, male elephant seals are around three
Years of high systolic blood pressure are linked to a greater risk for the two most common types of stroke. The results suggest that early diagnosis and sustained control of high blood pressure over the lifespan are critical to preventing stroke, especially in Black and Hispanic patients who are more likely to have uncontrolled hypertension.
Scientists have discovered that electrical currents may make Natural Killer (NK) cells -- our very own cancer-killing immune cells -- even better killers, which could have significant implications for treating some cancers. The scientists found that Tumour Treating Fields (TTF) in the laboratory (which mimic exposure of brain tumors to electric currents via a simple
3D-printed blood vessels, which closely mimic the properties of human veins, could transform the treatment of cardiovascular diseases. Strong, flexible, gel-like tubes -- created using a novel 3D printing technology -- could improve outcomes for heart bypass patients by replacing the human and synthetic veins currently used in surgery to re-route blood flow, experts say.
In a rigorous medical records study covering tens of thousands of patients, researchers conclude that some patients with preoperative anemia have better outcomes if they get iron infusions before surgery rather than standard red blood cell transfusions. In a rigorous medical records study covering tens of thousands of patients, Johns Hopkins Medicine researchers conclude that
An experimental drug originally developed to treat cancer may help clear HIV from infected cells in the brain, according to a new study. By targeting infected cells in the brain, drug may clear virus from hidden areas that have been a major challenge in HIV treatment. An experimental drug originally developed to treat cancer may
Scientists created new tools to study brain messenger proteins called neuropeptides in the brains of behaving animals, discovering they are the primary messengers in the fear circuit in mouse brains, and that multiple neuropeptides work together to achieve this--explaining why some clinical trials that target just one neuropeptide have failed. The new tools and findings
