100 percent oxygen resuscitation after brain injury may do more harm than good to children

The current standard practice of giving infants and children 100 percent oxygen to prevent brain damage caused by oxygen deprivation may actually inflict additional harm, researchers at UT Southwestern Medical Center have found.

Discovery of toxic key to Alzheimer’s disease memory loss

Using new scientific techniques, scientists have unlocked the cascade of molecular events that lead to Alzheimer's disease.

Nerve cells derived from stem cells may one day provide improved brain treatments

Scientists at the Burnham Institute for Medical Research have, for the first time, genetically programmed embryonic stem (ES) cells to become nerve cells when transplanted into the brain, according to a study published in The Journal of Neuroscience.

Pitt awarded $2.5 million to model how the brain and immune system function in response to illness, infection

In an effort to promote the application of mathematics to medical treatment, researchers in the University of Pittsburgh's Department of Mathematics will undertake a $2.5 million project to create models of how the brain and immune system function and change over time in response to certain illnesses, infections, and treatment.

New discovery could lead to new treatments for Alzheimer's

Rutgers researcher Karl Herrup and colleagues at Case Western Reserve University have discovered that a protein that suppresses cell division in brain cells effectively "puts the brakes" on the dementia that comes with Alzheimer's disease (AD). When the brakes fail, dementia results.

Australian researchers find important piece of Alzheimer's puzzle

Queensland Brain Institute (QBI) neuroscientists at UQ have discovered a new way to reduce neuronal loss in the brain of a person with Alzheimer's disease.

World's oldest woman had normal brain

A 115-year-old woman who remained mentally alert throughout her life had an essentially normal brain, with little or no evidence of Alzheimer's disease, according to a study in the August issue of Neurobiology of Aging.

Scientists closer to solving epilepsy mystery

Scientists in the United States believe they are a step closer to understanding why some people suffer from epileptic fits.

Human stem cells show promise against fatal children's diseases

Scientists have used human stem cells to dramatically improve the condition of mice with a neurological condition similar to a set of diseases in children that are invariably fatal, according to an article in the June issue of the journal Cell Stem Cell.

Flow of potassium ions in brain cells is key to sexual arousal

When it comes to sex, a female rat knows how to avoid a communication breakdown. To announce her sexual readiness, she will automatically arch her back, deflect her tail and stand rigid to allow an aroused male to mount.

Molecular fingerprint of cocaine addiction revealed

The first large-scale analysis of proteins in the brains of monkeys addicted to cocaine reveals new information on how long-term cocaine use changes the amount and activity of various proteins affecting brain function.

Intracellular antibody mops up mutant protein in Huntington's disease model

Scientists have created a tool for mopping up the clumps of mutant protein that drive neurodegeneration in Huntington's disease. Emory University researchers engineered a virus to make an intracellular antibody or "intrabody" against huntingtin, the protein whose mutant forms poison the brain cells of people with Huntington's.

Discovery of a molecular scaffold that guides connections between brain cells

Brain cells known as neurons process information by joining into complex networks, transmitting signals to each other across junctions called synapses. But "neurons don't just connect to other neurons," emphasizes Z. Josh Huang, Ph.D., "in a lot of cases, they connect to very specific partners, at particular spots."

Plant flavonoid luteolin reduces inflammatory response in the brain

Researchers at the University of Illinois report this week that a plant compound found in abundance in celery and green peppers can disrupt a key component of the inflammatory response in the brain. The findings have implications for research on aging and diseases such as Alzheimer's and multiple sclerosis.

Minocycline may find new life as a stroke treatment

An old intravenous antibiotic may have new life as a stroke treatment, researchers say. Minocycline appears to reduce stroke damage in multiple ways - inhibiting white blood cells and enzymes that, at least acutely, can destroy brain tissue and blood vessels, respectively, says Dr. David Hess, chair of the Department of Neurology in the Medical College of Georgia School of Medicine.

New dimension discovered in body clock rhythm

Research on what makes the body clock tick has led Dr Michael Hastings of the MRC Laboratory of Molecular Biology in Cambridge to discover a new and unanticipated cog in the human body clock. A patent for the compound involved has been filed by MRC Technology. The results, published in Science, could lead to therapies for people whose sleep is disrupted by shift work or old age.

Discovery of gene mutation which causes epilepsy and mental retardation - but only in women

An Australian and British research team have discovered a gene mutation that causes epilepsy and mental retardation but only in women.

Model shows how mutation tips biochemistry to cause Alzheimer's

Your fate can be determined by tiny events. Imagine you live in the city and you walk everywhere to get exercise - you are healthy and not afraid of getting mugged. You almost never eat breakfast so you don't stop at the donut shop on the way to work, until one day the manager replaces the girl at the counter with her pretty red-haired younger sister. This seemingly unimportant change in your world is just enough to overcome your ability to resist high-fat temptation. A million donuts later, your cholesterol level surges and then your heart gives out. Curse you, little red-haired girl!

Discovery of mechanism of action of antibiotic able to reduce neuronal cell death in brain

Virginia Commonwealth University researchers have discovered how an antibiotic works to modulate the activity of a neurotransmitter that regulates brain functions, which eventually could lead to therapies to treat Alzheimer's disease, Huntington's disease, epilepsy, stroke, dementia and malignant gliomas.
