Consent registry facilitates organ and tissue donation

Québec-Transplant and Héma-Québec applaud the government's commitment to assign the management of a consent registry for organ and tissue collection to the Régie de l'assurance-maladie du Québec (RAMQ), as stipulated in Bill 125, An Act to facilitate organ and tissue donation.

New MoDEL database to study biology of proteins

After four years of conducting intensive calculations in the supercomputer MareNostrum at the Barcelona Supercomputing Center, scientists headed by Modesto Orozco at the Institute for Research in Biomedicine (IRB Barcelona) have presented the world's largest data base on protein motions. Called MoDEL, this new database holds more than 1,700 proteins and is partially accessible through Internet to researchers worldwide. MoDEL has been developed to study the basic biology of proteins and to accelerate and facilitate the design of new pharmaceutical agents.

New findings shed light on biology of neuropsychiatric diseases

The biggest surprise to me was that we could rescue the autistic phenotype [in the human cells] to something close to normal, said Alysson Muotri of the University of California San Diego.

Equation to calculate energetic cost of walking

Any parent that takes their kid out for a walk knows that children tire more quickly than adults, but why is that? Do kids and small adults walk differently from taller people or do they tire faster for some other reason? Peter Weyand from Southern Methodist University, USA, is fascinated by the effect that body size has on physiological function.

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.

SLIT immunotherapy effective for long-term remission of bothersome allergy symptoms

Antihistamines and nasal steroids offer good short-term options for people with mild allergy, but allergy immunotherapy, better known as "allergy shots," is a preferred method for achieving long term remission of more bothersome allergy symptoms. Allergists mark the 100th anniversary of immunotherapy and present the latest advances at the American College of Allergy, Asthma and Immunology (ACAAI) annual scientific meeting in Phoenix, Nov. 11-16.

Neural pathways in amygdala regulates fear response

Fear arises in the almond-shaped brain structure known as the amygdala. It is the amygdala which processes the strange noise, shadowy figure or scary face and not only triggers palpitations or nausea but can also cause us to flee or freeze. That much has long been known about the function of this part of the brain. What remains largely unclear, however, is precisely how fear develops, and which of the countless neurons in the amygdaloid region are involved in this process.

GPR124 protein controls growth of blood vessels into brains

One protein single-handedly controls the growth of blood vessels into the developing brains of mice embryos, according to researchers at the Stanford University School of Medicine. Understanding how the protein, a cellular receptor, functions could help clinicians battle brain tumors and stroke by choking off or supplementing vital blood-vessel development, and may enhance the delivery of drugs across the blood-brain barrier.

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.

Study on flavors of laughter

Most scientific research on laughter is based on recordings of people pretending to laugh. But for Michael Owren of Georgia State University in Atlanta, this false laughter -- the sound of a canned sit-com laugh track -- is a pale imitation of the real thing. He studies the full vocabulary of chortles, giggles, guffaws we all use in everyday situations.

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.

Discovery on immune system paves way to new vaccine against pneumococcal disease

A new breakthrough in the fight against pneumonia, meningitis and septicaemia has been announced today by scientists in Leicester and Dublin. The discovery will lead to a dramatic shift in our understanding of how the body's immune system responds to infection caused by Streptococcus pneumoniae and pave the way for more effective vaccines.

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.

GPI launches new advocacy coalition to advance embryonic stem cell research in U.S.

The Genetics Policy Institute (GPI) today announced the launch of a new advocacy coalition of 30 organizations to foster public awareness and advance the cause of embryonic stem cell research in the United States.

Study finds arsenic improves survival rate in APL patients

Arsenic, a toxic compound with a reputation as a good tool for committing homicide, has a significant positive effect on the survival of patients with acute promyelocytic leukemia (APL), when administered after standard initial treatment, according to a new, multi-center study led by a researcher at Wake Forest University Baptist Medical Center.
