Thrombolysis in stroke- upto 4 and 1/2 hours
The time span in which treatment should be given for acute ischaemic stroke – i.e. stroke caused by a clot or other obstruction to the blood supply – can be lengthened. This according to a study from the Swedish medical university Karolinska Institutet, the results of which can bring about more effective and safer treatments for stroke sufferers.

Gabapentin may help recovering alcoholics
The study, published in the August issue of the journal Alcoholism: Clinical and Experimental Research, suggests that the drug gabapentin might be able to reduce insomnia in recovering alcoholics, and help them stay away from alcohol more successfully. The drug, often used to treat epilepsy and chronic pain, is not habit-forming and is not processed by the liver.

Stem cell restore muscle in mice with muscular dystrophy
By injecting purified stem cells isolated from adult skeletal muscle, researchers have shown they can restore healthy muscle and improve muscle function in mice with a form of muscular dystrophy. Those muscle-building stem cells were derived from a larger pool of so-called satellite cells that normally associate with mature muscle fibers and play a role in muscle growth and repair.

Mechanism for Parkinsonian tremor found
A typical symptom of Parkinson's disease is tremor in patients. A group of scientists, including Professor Peter Tass from Forschungszentrum Jülich have succeeded in demonstrating the mechanisms which cause the so-called tremor: neuron clusters in the depths of the brain drive the tremor. This discovery supports Tass' research activities aiming at developing a therapy for Parkinson's disease. A new deep brain pacemaker is to bring cells out of the diseased mode for good.

Japanese encephalitis virus causes 'double trouble' to brain
Japanese encephalitis (JE), commonly known as brain fever, is one of the prevalent mosquito-borne encephalitis in India and entire South East (SE) Asia. Besides resulting in thousand fatalities each year, JE virus (JEV) infection causes prominent neurological sequelae in approximately one-third of the survivors. Even those patients in the good recovery group commonly encounter psychiatric problems, which include mental retardation, learning disabilities, speech and movement disorders and behavioural abnormalities.

Spreading depolarisation after a stroke- warning sign
After a stroke, even unaffected areas of the brain are at risk – depolarization waves arise at the edges of the dead tissue and spread through the adjacent areas of the brain. If these waves are repeated, more cells die. This has previously been observed only in animal studies. A clinical study at the university hospitals of Heidelberg and Cologne along with the Max Planck Institute of Neurological Research in Cologne has shown for the first time that this phenomenon occurs after a stroke in humans and is a warning sign that more nerve cells will die.

Glutamate- involved in blocking response to anti-epileptic medication
Using a rodent model of epilepsy, researchers found one of the body’s own neurotransmitters released during seizures, glutamate, turns on a signaling pathway in the brain that increases production of a protein that could reduce medication entry into the brain. Researchers say this may explain why approximately 30 percent of patients with epilepsy do not respond to antiepileptic medications. The study, conducted by researchers at the National Institute of Environmental Health Sciences (NIEHS), part of the National Institutes of Health, and the University of Minnesota College of Pharmacy and Medical School, in collaboration with Heidrun Potschka’s laboratory at Ludwig-Maximilians-University in Munich, Germany, is available online and will appear in the May 2008, issue of Molecular Pharmacology.

Repeated methamphetamine use causes long-term adaptations in brains of mice, researchers find

The study, which appears in the April 10 issue of the journal Neuron, provides one of the most in-depth views of the mechanisms of methamphetamine addiction, and suggests that withdrawal from the drug may not undo the changes the stimulant can cause in the brain.

WHI follow-up study: Risks of long-term hormone therapy continue to outweigh benefits
New results from the Women's Health Initiative (WHI) confirm that the health risks of long-term use of combination (estrogen plus progestin) hormone therapy in healthy, postmenopausal women persist even a few years after stopping the drugs and clearly outweigh the benefits. Researchers report that about three years after women stopped taking combination hormone therapy, many of the health effects of hormones such as increased risk of heart disease are diminished, but overall risks, including risks of stroke, blood clots, and cancer, remain high. The WHI is sponsored by the National Heart, Lung, and Blood Institute (NHLBI) of the National Institutes of Health (NIH).

Cocaine's effects on brain metabolism may contribute to abuse
UPTON, NY - Many studies on cocaine addiction - and attempts to block its addictiveness - have focused on dopamine transporters, proteins that reabsorb the brain's reward chemical once its signal is sent. Since cocaine blocks dopamine transporters from doing their recycling job, it leaves the feel-good chemical around to keep sending the pleasure signal. Now a new study conducted at the U.S. Department of Energy's Brookhaven National Laboratory suggests that cocaine's effects go beyond the dopamine system. In the study, cocaine had significant effects on brain metabolism, even in mice that lack the gene for dopamine transporters.

Treatments that target these circuits may prove useful in controlling chronic overeating, according to the authors.

Biocapture surfaces produced for study of brain chemistry

By varying the identity and spacing of the tethered molecules, researchers can make the technique applicable to a wide range of bait molecules including drugs, chemical warfare agents, and environmental pollutants. Ultimately, the researchers also hope to identify synthetic biomolecules that recognize neurotransmitters so that they can fabricate extremely small biosensors to study neurotransmission in the living brain.

Smell experience during critical period alters brain
Unlike the circuitry of the visual system, that of the olfactory system was thought to be hardwired: Once the neurons had formed, no amount of sensory input could change their arrangement. Now researchers at Rockefeller University and their collaborators have upturned this scientific dogma by showing that there is a sensitive period during which the external environment can alter a circuit in the fly brain that detects carbon dioxide, a gas that alerts flies to food and mates. This research, to be published in the December 6 issue of Neuron, may suggest that this brain plasticity isn't limited to the carbon dioxide detection circuit. Rather, it may be a general feature of the olfactory system itself.
