Rett Syndrome research gets 'SMART' with Pepsi Challenge funding
Cincinnati, OH - The International Rett Syndrome Foundation (IRSF) believes that accelerating the pace of meritorious research, supporting families, and raising awareness are the minimum effort necessary to successfully search for treatments and a cure for one of the most devastating neurological diseases to affect young girls. On October 1, IRSF became the recipient of a $250,000 grant from the Pepsi Refresh contest that was officially confirmed later in the month. The contest was a highly-publicized and competitive online grant program to benefit non-profit organizations. In March 2010, IRSF entered the challenge when Donna Wright contacted IRSF's Director of Family Support, Paige Nues, to discuss the competition on behalf of her granddaughter, Naomi, who suffers from Rett syndrome.

Proof that a gut-wrenching complaint -- irritable bowel syndrome -- is not in your head
Irritable bowel syndrome makes life miserable for those affected -- an estimated ten percent or more of the population. And what irritates many of them even more is that they often are labeled as hypochondriacs, since physical causes for irritable bowel syndrome have never been identified. Now, biologists at the Technische Universitaet Muenchen (TUM) have shed new light on the matter: They have discovered mini-inflammations in the mucosa of the gut, which upset the sensitive balance of the bowel and are accompanied by sensitization of the enteric nervous system.

Neurons growing in line
In order to be able to understand complex organs such as the brain or the nervous system, simplified model systems are required. A group of scientists led by the Frankfurt brain researcher Erin Schuman has successfully developed a novel method to grow cultured neurons in order to investigate basic mechanisms of memory. The researchers grew two separate populations of neurons in microfluidic platforms. These neurons extended their processes through tiny grooves, to meet each other and form synaptic connections. Perpendicular to the grooves, a perfusion channel was constructed that allows the researchers to manipulate very small populations of synapses with drugs or neurotransmitters. The chambers are amenable to imaging, allowing researchers to visualize the dynamics of synapses, the movement of molecules within the neurons.

Depression associated with sustained brain signals
Depression and schizophrenia can be triggered by environmental stimuli and often occur in response to stressful life events. However, some people have a higher predisposition to develop these diseases, which highlights a role for genetics in determining a person's disease risk. A high number of people with depression have a genetic change that alters a protein that cells use to talk to each other in the brain. Imaging of people with depression also shows that they have greater activity in some areas of their brain. Unfortunately, the techniques that are currently available have not been able to determine why stress induces pathological changes for some people and how their genetics contribute to disease.

Repeated methamphetamine use causes long-term adaptations in brains of mice, researchers find
Repeatedly stimulating the mouse brain with methamphetamine depresses important areas of the brain, and those changes can only be undone by re-introducing the drug, according to research at the University of Washington and other institutions. 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.

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.

Overweight people may not know when they've had enough

Examining how the human brain responds to satiety messages delivered when the stomach is in various stages of fullness, the scientists have identified brain circuits that motivate the desire to overeat. Treatments that target these circuits may prove useful in controlling chronic overeating, according to the authors. The study is published online and will appear in the February 15, 2008 issue of NeuroImage.

Biocapture surfaces produced for study of brain chemistry
A research team at Penn State has developed a novel method for attaching small molecules, such as neurotransmitters, to surfaces, which then are used to capture large biomolecules.

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.

The researchers mapped out the mechanisms – components of which also are present in the human brain – that govern both kinds of responses.
