Metabolic syndrome patients need more vitamin C to break cycle of antioxidant depletion

A higher intake of vitamin C is crucial for metabolic syndrome patients trying to halt a potentially deadly cycle of antioxidant disruption and health-related problems, an Oregon State University researcher says. That’s important news for the estimated 35 percent of the U.S. adult population that suffers from the syndrome. “What […]

Cancer cells steer a jagged path

A jagged little protein appears to be key to how cancer stem cells differentiate and enable metastasis, according to researchers at Rice University and the Duke University School of Medicine. Rice scientists who have formed several theories on how cancer grows and spreads connected the dots for a more complete […]

Scientists are looking for a way to cut off melanoma's escape routes

Melanoma is an extremely dangerous cancer, which spreads quickly and is relatively hard to treat. One of the more effective strategies would be to stop cancer from spreading, making its presence a bit more local and, therefore, easier to treat. But how do you achieve that? Scientists from the University […]

An Errant Editing Enzyme Promotes Tumor Suppressor Loss and Leukemia Propagation

Writing in the journal Cancer Cell, researchers at University of California San Diego School of Medicine report that detection of “copy editing” by a stem cell enzyme called ADAR1, which is active in more than 20 tumor types, may provide a kind of molecular radar for early detection of malignancies and […]

Cutting off melanoma’s escape routes

Stopping melanoma from spreading to other parts of the body might be as simple as cutting off the blood supply to the cancer, according to researchers. Scientists from The University of Queensland’sDiamantina Institute have discovered stem cells which form blood vessels in tumours, and have identified how to ‘switch the cells off’. […]

Swim, Jump, Shoot, Lift: Paralympians reveal brain’s amazing ability to adapt

Professor Kimitaka Nakazawa built a career studying neurological rehabilitation after spinal cord injury. He had long been interested in sports physiology and when he moved to the University of Tokyo in 2009, he had the academic freedom to add studies of dancers and baseball pitchers to his research. It wasn't […]

Artificial Intelligence Can Detect Alzheimer’s Disease in Brain Scans Six Years Before a Diagnosis

Using a common type of brain scan, researchers programmed a machine-learning algorithm to diagnose early-stage Alzheimer’s disease about six years before a clinical diagnosis is made – potentially giving doctors a chance to intervene with treatment. No cure exists for Alzheimer’s disease, but promising drugs have emerged in recent years […]

New compound shows promise in treatment of Alzheimer’s

Yale researchers have identified a drinkable cocktail of designer molecules that interferes with a crucial first step of Alzheimer’s and even restores memories in mice, they report n the journal Cell Reports. The binding of amyloid beta peptides to prion proteins triggers a cascade of devasting events in the progression of […]

Sandia microneedles technique may mean quicker diagnoses of major illnesses

When people are in the early stages of an undiagnosed disease, immediate tests that lead to treatment are the best first steps. But a blood draw — usually performed by a medical professional armed with an uncomfortably large needle — might not be quickest, least painful or most effective method, […]

Better mouse model built to enable precision-medicine research for Alzheimer's

Incorporating genetic diversity into a mouse model of Alzheimer’s disease resulted in greater overlap with the genetic, molecular and clinical features of this pervasive human disease, according to a study funded by the National Institute on Aging (NIA), part of the National Institutes of Health. The study also suggests that […]

Want to improve your memory? Start drawing even if you're not good at it

There is nothing fun about getting old. One of the worst things is deterioration of mental capacities, such as memory. As people get older, retention of new information typically declines, but there are ways to delay and slow down this process. Scientists from the University of Waterloo found that drawing […]

Researchers unravel mystery of how, when DNA replicates

A team of Florida State University researchers has unlocked a decades-old mystery about how a critical cellular process is regulated and what that could mean for the future study of genetics. In cells, DNA and its associated material replicate at regular intervals, a process essential to all living organisms. This […]

How do hair follicles grow? A Yale-led study untangles the science

An outstanding question in dermatology that researchers have studied for decades is: How do hair follicles emerge from a sea of seemingly uniform skin cells during embryonic development? New research findings from a Yale-led team offer answers to that question, which may lead to strategies for regenerating lost hair follicles […]

Looking ‘outside the tumor’ to detect lung cancer

Scientists in Anant Madabhushi’s computational imaging lab at Case Western Reserve University have started thinking outside the box—or in their case, looking outside the tumor. They’re hoping that this novel computerized approach represents a historic leap in diagnosing cancer using just routine CAT scans. If proven successful, it would be […]

Novel drops could prevent vision loss after eye trauma or severe infections

Eye trauma or various infections often lead to impaired vision or even blindness. However, these conditions do not have such an effect in themselves – usually disability occurs due to scar tissue forming in cornea. This outer layer of the eye is transparent, but turns opaque due to scarring. Now […]
