Neuroscientists discover a critical early step of memory formation

Researchers at the Johns Hopkins University School of Medicine report in the July issue of Neuron how nerve cells in the brain ensure that Arc, a protein critical for memory formation, is made instantly after nerve stimulation. Paradoxically, its manufacture involves two other proteins - including one linked to mental retardation - that typically prevent proteins from being made.

New ependymoma genes identified

Scientists have isolated three important genes involved in the development of a type of childhood brain cancer- reveals a study published in the British Journal of Cancer.

Clinical trial advances cystic fibrosis therapy

Axentis Pharma AG has initiated a clinical phase IIa trial to assess the safety and tolerability of a new therapeutic formulation for the treatment of severe pulmonary infection in cystic fibrosis patients. The new formulation allows an established therapeutic agent to be delivered directly to the site of infection. The forthcoming trial will also compare the effects of two different doses of the new drug.

Human herpes virus 6 weaves itself into the DNA transferred from parents to babies

Parents expect to pass on their eye or hair color, their knobby knees or their big feet to their children through their genes. But they don't expect to pass on viruses through those same genes.

Atomic bomb's effect results in adult-onset thyroid cancer

Radiation from the atomic bomb blasts in Hiroshima and Nagasaki, Japan, in 1945, likely rearranged chromosomes in some survivors who later developed papillary thyroid cancer as adults, according to Japanese researchers.

Discovery of new genes for inflammatory bowel disease in children

Researchers have discovered two new genes that increase the risk of developing inflammatory bowel disease (IBD) in childhood.

Low levels of 'brain derived neurotrophic factor' may lead to obesity

A brain chemical that plays a role in long term memory also appears to be involved in regulating how much people eat and their likelihood of becoming obese, according to a National Institutes of Health study of a rare genetic condition.

Gleevec receives FDA priority review for gastrointestinal stromal tumors after surgery

Novartis has announced that Gleevec (imatinib mesylate) tablets, (known as Glivec (imatinib) outside the US, Canada and Israel), has been granted priority review status by the US Food and Drug Administration (FDA) as the first therapy to be reviewed for use after surgery in kit-positive gastrointestinal stromal tumors (GIST).

FDA clears non-invasive test to help manage heart transplant patients

The U.S. Food and Drug Administration has announced it has cleared for marketing a non-invasive test that uses molecular expression techniques to assist doctors in managing heart transplant patients post-surgery for potential organ rejection.

Researchers show how DNA repairs may reshape the genome

Researchers at Duke University Medical Center and at the National Institute of Environmental Health Sciences (NIEHS) have shown how broken sections of chromosomes can recombine to change genomes and spawn new species.

Australian researchers reveal how cancers become more aggressive

A team of Australian scientists have discovered how some cancers are able to mutate into more aggressive and potentially fatal cancers in the human body.

Cancer survival secrets discovered by Australian researchers

A team of Monash University researchers has uncovered the role of a family of enzymes in the mutation of benign or less aggressive tumours into more aggressive, potentially fatal, cancers in the human body.

Molecular bridge serves as a tether for a cell's nucleus

A cell's nucleus - home of it its most precious contents - is a delicate envelope that, without support, is barely able to withstand the forces that keep it in place. Now, researchers have discovered a network of molecules in the nuclear membrane that provide the nucleus with rigidity and also facilitate a previously undiscovered form of communication between the cell's nucleus and its cytoplasm.

Researchers show how new chemotherapy drugs kill cancerous tumors

Dr Stephen Taylor and Karen Gascoigne at the University of Manchester's Faculty of Life Sciences have taken a new systematic approach to studying anti-mitotic drugs, which are used extensively for breast or ovarian cancer in the UK.

Discovery of vital key to cancer

University of Manchester scientists have uncovered the 3D structure of Mps1 - a protein that regulates the number of chromosomes during cell division and thus has an essential role in the prevention of cancer - which will lead to the design of safer and more effective therapies.

Scientists identify possible cause of endometriosis

Scientists at the University of Liverpool have identified an enzyme that could be responsible for a condition called endometriosis - the most common cause of pelvic pain in women.

Anti-reflux surgery - research may lead to changes in treatment recommendations

Researchers at Wake Forest University Baptist Medical Center have found that the reflux and swallowing problems that are common symptoms in patients with Rett syndrome and other neurological impairments, may be caused by a different mechanism than they are in healthy individuals. The finding leaves researchers to wonder if these patients truly benefit from anti-reflux surgery commonly performed in these children.
