While there is currently no cure for PD, one treatment that has proved promising for alleviating symptoms of the disorder is deep brain stimulation (DBS).

Our hearts beat around 100,000 times a day—and do so throughout our entire lives. They draw the energy for this from the mitochondria. As the "powerhouses of the cells," mitochondria produce 95% of adenosine triphosphate (ATP), the body's most important energy currency. If the mitochondria are impaired and cannot function properly, the heart muscle cells lack the strength to pum...

Using a microaxial flow pump prior to and during cardiac stenting procedures for patients with severe heart attacks who don't have cardiogenic shock does not significantly reduce heart damage. That is the major finding from the first clinical trial of its kind to analyze the effect of resting the heart in high-risk heart attack patients to see if it reduces the size of the heart...

Results of a new study conclude that a pathology tool powered by artificial intelligence can predict whether a patient with extensive-stage small cell lung cancer will respond to platinum-based chemotherapy—before treatment has begun, and without additional biopsies. That means patients can avoid treatments that are unlikely to help them, have a chance to enroll earlier in clini...
