Researchers improvise fruit fly as a model system to study brain development, disorders

VIB researchers attached to the K.U.Leuven have improved the fruit fly as a model for studying the connections between brain cells. The researchers developed a specific marker for a part of the fly's nerve cell which had previously been difficult to distinguish. Their discovery will not only contribute to gaining a better insight into brain development but also makes the fruit fly into a better model system for studying brain development and brain disorders.

New mathematical model may help predict anemia risk

A collaboration between a physician-researcher at Massachusetts General Hospital (MGH) and a mathematician from Harvard University has led to development of a mathematical model reflecting how red blood cells change in size and hemoglobin content during their four-month lifespan.

U-M researchers develop simple mathematical model to predict whooping cough transmission

Strategies for preventing the spread of whooping cough on the rise in the United States and several other countries in recent years should take into account how often people in different age groups interact, research at the University of Michigan suggests.

Scientists to present new findings from NIAID-funded research at ACAAI Annual Meeting

The 2010 Annual Meeting of the American College of Allergy, Asthma & Immunology (ACAAI) brings together leading allergists and immunologists from around the world.

Researchers study Rett neurons in a Petri dish

A collaborative effort between researchers at the Salk Institute for Biological Studies and the University of California, San Diego, successfully used human induced pluripotent stem (iPS) cells derived from patients with Rett syndrome to replicate autism in the lab and study the molecular pathogenesis of the disease.

Scientists unveil mechanism of liver regeneration

The liver's unique ability among organs to regenerate itself has been little understood. Now Weill Cornell Medical College scientists have shed light on how the liver restores itself by demonstrating that endothelial cells the cells that form the lining of blood vessels play a key role.

Scientists create functional neurons to study ASD development

Using induced pluripotent stem cells from patients with Rett syndrome, scientists at the University of California, San Diego School of Medicine have created functional neurons that provide the first human cellular model for studying the development of autism spectrum disorder (ASD) and could be used as a tool for drug screening, diagnosis and personalized treatment.

Research on fruit flies reveal novel human pain gene

While it has become clear in recent years that susceptibility to pain has a strong inherited component, very little is known about actual "pain genes" and how they work. In the November 12th issue of Cell, researchers at Children's Hospital Boston and their collaborators report on a novel human pain gene. People with minor variations in this gene showed clear differences in susceptibility to acute heat pain and chronic back pain.

Research unveils epigenetic function of MECP2 gene tht cause neuropsychiatric disorders

The laboratory of Huda Zoghbi, where the discovery that mutations in the gene MECP2 cause the severe childhood neurological disorder Rett Syndrome was made, has taken yet another step toward unraveling the complex epigenetic functions of this gene, implicated also in cases of autism, bipolar disease and childhood onset schizophrenia. The November 11 issue of Nature reports that removing MECP2 from a small group of neurons that typically make the inhibitory neurotransmitter, GABA, recapitulates many symptoms of Rett as well as numerous neuropsychiatric disorders.

PenCLAHRC provides funding to support C. difficile research

The Peninsula Collaboration for Leadership in Applied Health Research and Care (PenCLAHRC) has provided funding to support joint research between the University of Exeter and the Royal Devon & Exeter NHS Foundation Trust to investigate why some cases of Clostridium difficile infection (CDI) are more difficult to treat than others and also why some cases result in more incidences of relapses.

Diabetic drug may retard growth of fluid-filled cysts in PKD: Research

Researchers report that a drug commonly used to treat diabetes may also retard the growth of fluid-filled cysts of the most common genetic disorder, polycystic kidney disease.

NCI awards $11.5 million to Fred Hutchinson Center for breast cancer research

The National Cancer Institute has awarded $11.5 million to Fred Hutchinson Cancer Research Center to lead a five-year, Seattle-based breast cancer research consortium. The goal of the endeavor is to positively impact breast cancer prevention, detection, treatment and care of women who have or are at risk for the disease.

Women and cancer today

Experts have warned that women who have their breasts removed out of fear of a high hereditary risk of breast cancer may be doing so needlessly. Genetic tests like for the BRCA mutations have predicted a high risk of getting breast cancer in women with many breast cancer sufferers among their first degree relatives. Earlier studies suggest the risk of the mutation to predict the cancer 87% of the time. Now experts want that this is an overestimate.

Neuron subtypes control level of fear output from amygdala

The eerie music in the movie theater swells; the roller coaster crests and begins its descent; something goes bump in the night. Suddenly, you're scared: your heart thumps, your stomach clenches, your throat tightens, your muscles freeze you in place. But fear doesn't come from your heart, your stomach, your throat, or your muscles. Fear begins in your brain, and it is there specifically in an almond shaped structure called the amygdala that it is controlled, processed, and let out of the gate to kick off the rest of the fear response.

German Genetic Diagnostics Act in need of amendment

Many aspects of the German Genetic Diagnostics Act (Gendiagnostikgesetz) are out of touch with the latest technology, almost impossible to implement in clinical practice, or even detrimental to the success of recognised screening tests, such as newborn screening. The Act, which came into force in February 2010, is in desperate need of amendment.

Portugal research groups awarded Gates Foundation grants

Two research groups in Portugal are to receive Grand Challenges Exploration Grants from the Bill & Melinda Gates Foundation. One of these research teams is led by Miguel Prud-ncio, at the Instituto de Medicina Molecular (IMM), and the other by Miguel Soares, at the Instituto Gulbenkian de Ci-ncia (IGC) together with Henrique Silveira, at the Instituto de Higiene e Medicina Tropical (IHMT).

NJIT expert to discuss history of sickle cell disease at NIH symposium

The history of sickle cell disease in the 20th century and its link to race is the focus of a Nov. 16, 2010 talk at a national symposium by NJIT Associate Professor Stephen Pemberton, PhD, an expert on the history of diseases. Pemberton will speak and join a panel discussion at the National Institutes of Health (NIH), Bethesda, 100th anniversary symposium commemorating the discovery of sickle cell disease by Chicago physician James B. Herrick.

MqsA and MqsR protein complex can disrupt drug-resistant biofilm formation

When a foreign object such as a catheter enters the body, bacteria may not only invade it but also organize into a slick coating - a biofilm - that is highly resistant to antibiotics. Like sophisticated organized crime rings, biofilms cannot be defeated by a basic approach of conventional means. Instead doctors and drug developers need sophisticated new intelligence that reveals the key players in the network and how they operate. New research led by biologists at Brown University provides exactly that dossier on some key proteins in the iconic bacterium E. coli.
