New treatment options for the deadliest of cancers

A new way to target a mutant protein which can cause the deadliest of cancers in humans has been uncovered by scientists at the University of Leeds.The mutated form of the RAS protein has been referred to as the “Death Star” because of its ability to resist treatments and is found in 96% of pancreatic […]

Machine learning helps in predicting when immunotherapy will be effective

When it comes to defense, the body relies on attack thanks to the lymphatic and immune systems. The immune system is like the body’s own personal police force as it hunts down and eliminates pathogenic villains. “The body’s immune system is very good at identifying cells that are acting strangely. These include cells that could […]

Study finds variations in quantitative MRI scanners’ measurements

Magnetic resonance imaging (MRI) is widely used in medicine to detect, diagnose and treat diseases such as cancer, while relying on experts’ interpretation of images. Quantitative MRI, which obtains numerical measurements during the scans, can now potentially offer greater accuracy, repeatability and speed—but rigorous quality control is needed for it to reach its full potential, […]

Feedback activity in the visual cortex is necessary for the perception of objects

An important function of vision is to segregate relevant figures from the irrelevant background. A visual stimulus drives a cascade of neural activity from low-level to higher level visual brain areas. The higher areas also provide feedback to the lower areas, where figures elicit more activity than the background, as if figures in the brain […]

New research moves novel gene therapy for heart failure closer to the clinic

Research at Baylor College of Medicine, the Texas Heart Institute and collaborating institutions is moving a novel promising gene therapy to treat heart failure closer to the clinic. Published in Science Translational Medicine, the study showed that knocking down the Hippo signaling pathway in cardiomyocytes in the hearts of pigs after they had a heart […]

New microchip sensor measures stress hormones from drop of blood

Cortisol and other stress hormones regulate many aspects of our physical and mental health, including sleep quality. High levels of cortisol can result in poor sleep, which increases stress that can contribute to panic attacks, heart attacks and other ailments. Currently, measuring cortisol takes costly and cumbersome laboratory setups, so the Rutgers-led team looked for […]

Study finds breast cancer’s response to tumor stiffness may predict bone metastasis

In cases of breast cancer, bone metastasis—when cancer cells spread to new sites in the bone—causes the most breast cancer-related harm and is often incurable in advanced disease. A new study by University of Arizona Health Sciences researchers found that cancer cells become more aggressive when exposed to tissue stiffening and that these changes persist […]
