NIH launches undiagnosed diseases program

The National Institutes of Health (NIH) today announced a new clinical research program that will aim to provide answers to patients with mysterious conditions that have long eluded diagnosis. Called the Undiagnosed Diseases Program, the trans-NIH initiative will focus on the most puzzling medical cases referred to the NIH Clinical Center in Bethesda, Md., by physicians across the nation.

Nasal gel to fight superbug MRSA

British scientists are well on the way to developing a new drug to fight the 'superbug' Methicillin-resistant Staphylococcus aureus (MRSA).

A transgenic monkey model of Huntington's disease developed

Scientists have developed the first genetically altered monkey model that replicates some symptoms observed in patients with Huntington's disease, according to a new study funded by the National Institutes of Health. Researchers are now able to better understand this complex, devastating and incurable genetic disorder affecting the brain.

Ashwell receptor plays key role in reducing coagulation abnormalities during infection and sepsis

In research that solves the longest-standing mystery in glycobiology - a field that studies complex sugar chains called glycans - researchers at the University of California, San Diego School of Medicine have discovered that a molecule in the liver of all animals, called the Ashwell receptor, is critical in helping the body fight off the abnormal and lethal blood clotting caused by bacterial infection.

Lubiprostone brings relief for many IBS patients who experience constipation

Many patients may soon find relief from the bloating, cramping, abdominal pain and constipation associated with irritable bowel syndrome, or IBS.

New dimension discovered in body clock rhythm

Research on what makes the body clock tick has led Dr Michael Hastings of the MRC Laboratory of Molecular Biology in Cambridge to discover a new and unanticipated cog in the human body clock. A patent for the compound involved has been filed by MRC Technology. The results, published in Science, could lead to therapies for people whose sleep is disrupted by shift work or old age.

DNA vaccines boosted by dendritic cells

The concept sounds ideal: vaccines made of DNA that could be taken in by other cells and give instructions for how to fight off different diseases. The reality, however, has fallen short. Although DNA vaccines have been around for about 15 years and shown lots of promise for HIV, SARS and influenza vaccines during preclinical testing in mice, researchers have yet to make them potent enough to be helpful in humans.

Palatal surgery in less lexically advanced, younger children associated with better speech outcomes

A new study published in The Cleft Palate-Craniofacial Journal has found that the timing of palatal surgery and size of lexicon, or vocabulary, in children are important factors to consider in determining the most beneficial management of children with cleft palate.

First evidence of native dendritic cells in brain

In a finding that has the potential to change the way researchers think about the brain, scientists at Rockefeller University have found dendritic cells where they've never been seen before: among this organ's neurons and connective cells.

Drug therapy for phenylketonuria reverses heart damage

A pricy drug used to treat a rare but well-known genetic disorder may hold wider promise as a treatment for millions of Americans with potentially lethal enlarged hearts, due mainly to high blood pressure, a study from Johns Hopkins shows.

Simple, painless hair test detects breast cancer

A test developed by Australian scientists which promises to be able to pick up breast cancer from a hair sample, could be commercially available later this year.

Arsenic-based agent shown to help eradicate leukemia-initiating cells

In both leukemia and solid tumors, there exists among the multitude of warrior cancer cells a small subgroup that work undercover, patiently lying in wait to launch their attacks. Known as either cancer initiating cells (CICs) or leukemia initiating cells (LICs), these stealth populations are impervious to conventional chemotherapy and undaunted by targeted cancer therapies. When a leukemia patient relapses following a period of remission, it is the LICs that bear responsibility for the disease's reemergence.

Study looks at phantom limb syndrome

Losing a limb can be a traumatic experience and, in some cases, emotional and physical pain can linger for years. To better understand the phenomenon, dubbed "phantom limb syndrome," Université de Montreal graduate student Emma Duerden is inviting amputees to come forward and share their experiences for a major study.

Molecular pathway in muscle helps explain effectiveness of diabetes interventions

Scientists at the National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIAMS), a part of the National Institutes of Health (NIH), demonstrate for the first time in a mouse model that skeletal muscle cells cultured in a low-calorie environment refrain from differentiating, an energy-demanding process by which cells mature and specialize.

Starpharma reports positive VivaGel clinical study results

Starpharma Holdings Limited today announced positive results of a clinical trial that achieved all its objectives demonstrating that 3% SPL7013 Gel (VivaGel) was safe and well-tolerated in sexually abstinent women when administered vaginally, twice daily for 14 days.

microRNAs provide more clues to genetics of schizophrenia

Researchers at Columbia University Medical Center have illuminated a window into how abnormalities in microRNAs, a family of molecules that regulate expression of numerous genes, may contribute to the behavioral and neuronal deficits associated with schizophrenia and possibly other brain disorders.

New clues into how preeclampsia may surface in some pregnancies

The COMT gene - known already for its role in schizophrenia - has been found to play a role in preeclampsia, according to a report in the advance on-line issue of Nature.

Fruit fly avoidance mechanism could lead to new ways to control pain in humans

At first, fruit flies eat like horses. Hatching inside over-ripe fruit where they were laid, they feed wildly in the sugar-rich environment until nature sends them an offer they can't refuse. To survive, they must leave the fruit, wander off and burrow into the earth where they avoid food as if it were poison. Only then can the larvae grow and hatch into flies that will take wing to lay their own eggs.

New theory suggests how hepatitis C may cause rare immune disease

Of the hepatitis alphabet, the C variant may be the nastiest. In 1990, researchers observed that most patients with hepatitis C also develop a rare autoimmune disease called mixed cryoglobulinemia, a condition that frequently leads to cancer, arthritis or both.

Radioactive carbon-14 determines the number of fat cells remains constant in all body types

The radioactive carbon-14 produced by above-ground nuclear testing in the 1950s and '60s has helped researchers determine that the number of fat cells in a human's body, whether lean or obese, is established during the teenage years. Changes in fat mass in adulthood can be attributed mainly to changes in fat cell volume, not an increase in the actual number of fat cells.
