Immune System Of Newborn Babies Stronger Than Previously Thought

The team discovered that whilst T cells in newborn babies are largely different to those in adults, it is not because they are immunosuppressed; rather, they manufacture a potent anti-bacterial molecule known as IL8 that has not previously been considered a major product of T cells, and that activates neutrophils to attack the body's foreign invaders.

Contrary to what was previously thought, newborn immune T cells may have the ability to trigger an inflammatory response to bacteria, according to a new study led by King’s College London. Although their immune system works very differently to that of adults, babies may still be able to mount a strong immune defense, finds the [...]

Ultrasound Enhancement Provides Clarity To Damaged Tendons, Ligaments

The potential was hidden in plain sight, pretty much since the beginning of medical ultrasound. But it took an expert in earthquake waves to unearth the idea that sound waves reflected from human bodies could reveal not only their internal shape, but also their condition. Earthquakes create waves in Earth that are interpreted with seismographs. [...]

Battling Superbugs: Two New Technologies Could Enable Novel Strategies For Combating Drug-Resistant Bacteria

In recent years, new strains of bacteria have emerged that resist even the most powerful antibiotics. Each year, these superbugs, including drug-resistant forms of tuberculosis and staphylococcus, infect more than 2 million people nationwide, and kill at least 23,000. Despite the urgent need for new treatments, scientists have discovered very few new classes of antibiotics [...]

On/Off Switch For Aging Cells Discovered By Scientists

Scientists at the Salk Institute have discovered an on-and-off “switch” in cells that may hold the key to healthy aging. This switch points to a way to encourage healthy cells to keep dividing and generating, for example, new lung or liver tissue, even in old age. In our bodies, newly divided cells constantly replenish lungs, [...]

Cooling Of Dialysis Fluids Protects Against Brain Damage

While dialysis is an essential treatment for many patients with kidney disease, it can cause damage to multiple organs, including the brain and heart, due to the sudden removal of bodily fluids. Cooling dialysis fluids can protect against brain damage, new research shows.

While dialysis can cause blood pressure changes that damage the brain, cooling dialysis fluids can protect against such effects. The findings come from a study appearing in an upcoming issue of the Journal of the American Society of Nephrology (JASN). The cooling intervention can be delivered without additional cost and is simple to perform. While [...]
