The eye can provide a very reliable way of diagnosing cerebral malaria, researchers in Malawi have shown. By looking at the changes to the retina, doctors are able to determine whether an unconscious child is suffering from this severe form of malaria or another, unrelated illness, leading to the most appropriate treatment.
Ulrike Schmidt, Professor in Eating Disorders, will be speaking at the DANA Centre in South Kensington on 14 November 2006 at Beyond Slim, a public event organised jointly by the Institute of Psychiatry and the European Dana Alliance for the Brain. The evening will be chaired by Professor Iain Campbell and will also feature contributions from the Eating Disorders Association and a personal account from someone living with an eating disorder.
An observational study of about 82,000 males and females in Sweden found a lower risk of pancreatic cancer in subjects with a high intake of folate-rich foods — green, leafy vegetables; cruciferous vegetables, such as broccoli, cauliflower and cabbage; oranges; legumes and whole grains.
The stickiness of human neurons may have been a key factor in why the human brain evolved beyond the brains of our primate relatives. In a study comparing the genomes of humans, chimpanzees, mice and other vertebrates, researchers at the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) and Joint Genome Institute (JGI) found a strikingly high degree of genetic differences in DNA sequences that appear to regulate genes involved in nerve cell adhesion molecules. Cell adhesion controls many aspects of brain development including growth and structure, and enables neurons to connect with other neurons and supportive proteins. Differences in the molecular connections of human neurons compared to the neurons of chimps, mice and other animals, could help explain why the human brain is capable of far more complex cognitive functions.
Fundamental theories regarding consciousness, emotion and quality of life in sufferers of paralysis from Amyotrophic Lateral Sclerosis (ALS, also known as ‘Lou Gerhig’s disease’) are being challenged based on new research on brain-computer interaction. ALS is a progressive disease that destroys neurons affecting movement. The study appears in the latest issue of Psychophysiology. The article reviews the usefulness of currently available brain-computer ?interfaces (BCI), which use brain activity to communicate through external devices, such as computers.
A pediatric oncologist at Brenner Children’s Hospital is evaluating whether a drug typically used to treat Alzheimer’s patients will help brain cancer survivors avoid the learning and memory problems that are common after radiation therapy.
A growth factor known to be important for the survival of many types of cells stimulates rapid extension of corticospinal motor neurons — critical brain cells that connect the cerebral cortex with the spinal cord and that die in motor neuron diseases like amyotrophic lateral sclerosis (ALS or Lou Gehrig’s disease).
One hundred years after the first diagnosis of Alzheimer’s disease Nov. 3, 1906, researchers at the Yerkes National Primate Research Center, Emory University, are focusing on neuroscience, immunology and vaccine research to better understand how AD develops and progresses as well as to advance the treatment and prevention of this progressive brain disorder. AD, which currently affects 20 million Americans, gradually destroys memory and the ability to learn, reason, make judgments and communicate.
New evidence to explain how a common tropical fish mends a broken heart may suggest methods for coaxing the damaged hearts of mammals to better heal, researchers report. The researchers found that the hearts of zebrafish harbor progenitor cells that spring into action to restore wounded heart muscle. Cells from a membrane layer that surrounds the heart, called the epicardium, follow suit, invading the wounded cardiac tissue and stimulating the growth of new blood vessels.
Infant abuse may be perpetuated between generations by changes in the brain induced by early experience, research shows. A research team found that when baby rhesus monkeys endured high rates of maternal rejection and mild abuse in their first month of life, their brains often produced less serotonin, a chemical that transmits impulses in the brain. Low levels of serotonin are associated with anxiety and depression and impulsive aggression in both humans and monkeys.
