Low-carbohydrate diet helps reduce growth of glioblastoma tumor cells in mouse models

University of Florida Health researchers have slowed a notoriously aggressive type of brain tumor in mouse models by using a low-carbohydrate diet.

Radiation plus chemotherapy improves survival of low-grade brain cancer patients

New clinical-trial findings show that patients with a low-grade form of brain cancer who are treated with radiation plus a combination of chemotherapy drugs have better survival than patients treated with radiation alone.

Mouse model offers insight into molecular, neurological basis of stuttering

Mice that vocalize in a repetitive, halting pattern similar to human stuttering may provide insight into a condition that has perplexed scientists for centuries, according to a new study by researchers at Washington University School of Medicine in St. Louis and the National Institutes of Health.

Genetic modification of common virus gives extra weapon to kill cancer cells

A common flu virus could be used to overcome patients' resistance to certain cancer drugs -- and improve how those drugs kill cancer cells, according to new research from Queen Mary University of London.

Removal of Dnmt1 enzyme during OPC differentiation could lead to neurological symptoms

The removal of the enzyme Dnmt1 during oligodendrocyte progenitor cell (OPC) differentiation in the central nervous system resulted in inefficient myelin formation and neurological deterioration, including loss of control of bodily movements, in mice, according to a study conducted at the Icahn School of Medicine at Mount Sinai and published today in the medical journal Cell Reports. The results could lead to a new understanding of multiple sclerosis and other myelin disorders in humans.

Newly developed implantable device can deliver chemotherapy drugs directly to pancreatic tumors

Pancreatic cancer is the third leading cause of cancer deaths in the United States, in part because it is very difficult for chemotherapy drugs to reach the pancreas, which is located deep within the abdomen.

FOXO proteins affect dozens of genes common to worms, flies, mice and humans

Whether a creature is a worm, a fly, a mouse, or a human, death inevitably awaits. And not only do these organisms share a common fate, but also, according to a new study, they may share some of the specific mechanisms of mortality. The researchers found that in all four species, there are 46 genes regulated by the same family of "FOXO" proteins known to be central in aging and longevity.

Adolescent obesity linked to elevated risk of cardiovascular mortality in midlife

A nationwide study of 2.3 million Israeli adolescents, examined from 1967 through 2010, finds an association between elevated body-mass index in late adolescence, and subsequent cardiovascular mortality in midlife.

Scientists identify key pathway that regulates 'switch' between wakefulness and sleep

Falling asleep and waking up are key transitions in everyone's day. Millions of people have trouble with these transitions - they find it hard to fall asleep or stay asleep at night, and hard to stay awake during the day. Despite decades of research, how these transitions work - the neurobiological mechanics of our circadian rhythm - has remained largely a mystery to brain scientists.

Heavy marijuana use may lead to lower dopamine release in the brain

In a recent study, researchers found evidence of a compromised dopamine system in heavy users of marijuana. Lower dopamine release was found in the striatum - a region of the brain that is involved in working memory, impulsive behavior, and attention. Previous studies have shown that addiction to other drugs of abuse, such as cocaine and heroin, have similar effects on dopamine release, but such evidence for cannabis was missing until now.

Slow-wave sleep may promote consolidation of recent memories

Research strongly suggests that sleep, which constitutes about a third of our lives, is crucial for learning and forming long-term memories. But exactly how such memory is formed is not well understood and remains, despite considerable research, a central question of inquiry in neuroscience.

Inflammation after stroke may help the brain to self-repair

After a stroke, there is inflammation in the damaged part of the brain. Until now, the inflammation has been seen as a negative consequence that needs to be abolished as soon as possible. But, as it turns out, there are also some positive sides to the inflammation, and it can actually help the brain to self-repair.

Willow herb extracts may be beneficial in treating multi-drug resistant bacterial and fungal infections

A common herb could help reduce antibiotic doses and result in less severe side effects in treatments against multi-drug resistant microorganisms.

Johns Hopkins study suggests updated universal screening for hepatitis C virus

A review of blood samples for nearly 5,000 patients seen at The Johns Hopkins Hospital Emergency Department suggests that federal guidelines for hepatitis C virus (HCV) screening may be missing up to a quarter of all cases and argues for updated universal screening.
