Preparing for the respiratory virus season: A guide for families

As respiratory virus season begins, pediatric experts are preparing for an expected rise in cases of Respiratory Syncytial Virus (RSV), which can cause cold-like symptoms in most people but serious illness in infants and older adults.

Preclinical study shows aged garlic extract improves memory and reduces anxiety

Long-term aged garlic extract supplementation improved specific anxiety-related behaviors and enhanced memory and learning in aging mice. Proteomic profiling revealed extensive hippocampal and cortical molecular changes linked to synaptic signaling, neuroplasticity, and stress-response pathways.

Understanding leptin's dual function in MAFLD pathogenesis

Metabolic dysfunction-associated fatty liver disease (MAFLD) has emerged as a predominant chronic liver condition globally, intricately linked with obesity, type 2 diabetes (T2DM), and metabolic syndrome.

Cardiologists recommend reassessing need for additional stents later

A blocked coronary artery causing an acute heart attack must be opened immediately with a stent procedure. However, if other coronary arteries also appear to be narrowed, it is safe to wait and treat those later. This approach cuts the number of stent procedures in half, according to cardiologists from Radboud university medical center, writing in The New England Journal of Medicine.

Tiny antibiotic traces found to greatly accelerate resistance spread

Antibiotic resistance is widely recognized as one of the most urgent public health challenges of the twenty first century.

Machine learning model boosts success of liver transplants from circulatory death donors

There are more candidates on the waitlist for a liver transplant than there are available organs, yet about half the time a match is found with a donor who dies after cardiac arrest following the removal of life support, the transplant must be canceled.

Scientists discover hidden weakness in Lyme disease bacterium

For decades, Lyme disease has frustrated both physicians and patients alike. Caused by the corkscrew-shaped bacterium Borrelia burgdorferi, the infection, if left untreated, can linger for months, leading to fever, fatigue and painful inflammation.

Breakthrough in bone regeneration using nanoparticle-stem cell hybrid

A research team in South Korea has successfully developed a novel technology that combines nanoparticles with stem cells to significantly improve 3D bone tissue regeneration.

Scientists reveal mathematical law governing limits of biological growth

A research team including a scientist of Earth-Life Science Institute (ELSI) at Institute of Science Tokyo, Japan, has identified a novel principle in biology that mathematically explains why the growth of organisms slows as nutrients become more abundant-a phenomenon known as "the law of diminishing returns."

Stress-induced neuron loss shown to disrupt blood flow and neural communication

While the exact causes of neurodegenerative brain diseases like Alzheimer's and dementia are still largely unknown, researchers have been able to identify a key characteristic in affected brains: reduced blood flow.

The caffeine conundrum in rapid depression treatments

Perhaps the most intriguing implication of recent breakthrough research lies in an unexpected connection: the most rigorous mechanistic dissection of rapid antidepressant action identifies adenosine as the critical mediator, yet adenosine receptors are the primary target of caffeine, the world's most widely consumed psychoactive substance.

Earlier blood transfusion reduces heart complications post-surgery in high-risk patients

An earlier blood transfusion- done when hemoglobin levels were higher - after major general or vascular surgery among people with heart disease was associated with a lower risk of some complications but not the most severe ones, according to a preliminary late-breaking science presentation today at the American Heart Association's Scientific Sessions 2025.

MRI-based blood flow testing offers better answers for unexplained chest pain

Chest pain may still be angina even when coronary angiogram testing shows the main heart arteries look clear. Using stress cardiac stress MRI testing to measure blood flow around the heart appears to improve diagnosis and patient quality of life.

Study links dysautonomia to breathing problems in chronic fatigue patients

Chronic fatigue syndrome leaves patients exhausted and struggling with brain fog - and it typically gets worse after mental or physical exercise, a phenomenon called post-exertional malaise.

Death risk found to be six times higher among hospitalized patients with dyspnea

The risk of dying is six times higher among patients who become short of breath after being admitted to hospital, according to research published today (Monday) in ERJ Open Research. Patients who were in pain were not more likely to die.

Genetic and cellular mechanisms underlying steatotic liver disease

Steatotic liver disease (SLD), mainly encompassing metabolic dysfunction-associated steatotic liver disease (MASLD), alcohol-related liver disease (ALD), and metabolic dysfunction and ALD (MetALD), has emerged as the dominant cause of chronic liver disease worldwide, displacing viral hepatitis as the primary aetiology.
