Raltegravir drug combo works against highly resistant strain of HIV

A study involving an international team of scientists has discovered that a new drug when combined with other anti-HIV medications, is particularly effective against a highly resistant strain of the HIV virus.

New technique measures formation of clumps of proteins in protein-based pharmaceuticals

Scientists at the National Institute of Standards and Technology (NIST) have developed a technique to measure the formation of clumps of proteins in protein-based pharmaceuticals.

Endurance exercise makes heart younger

Absence may make the heart grow fonder, but endurance exercise seems to make it younger. According to a study conducted at Washington University School of Medicine in St. Louis, older people who did endurance exercise training for about a year ended up with metabolically much younger hearts.

Fish oil supplements could slow wound healing

A recent study shows that popular fish oil supplements have an effect on the healing process of small, acute wounds in human skin. But whether that effect is detrimental, as researchers initially suspected, remains a mystery.

PET-CT scanners detect secondary head and neck cancers

For patients with head and neck cancer, accurately determining how advanced the cancer is and detecting secondary cancers usually means undergoing numerous tests - until now.

Link between small birth size and changes to the CV system that predispose to disease in later life

Researchers have found the first evidence that smaller size at birth is associated with specific alterations in the functioning of the heart and circulation in children and that these changes differ between boys and girls.

Notch protein helps human embryonic stem cells 'decide' their own fate

Researchers at Johns Hopkins have discovered that the Notch protein helps human embryonic stem cells 'decide' their own fate, a finding which may eventually be useful in programming cells for the development of stem cell therapies. Their results are reported in the May 2008 issue of Cell Stem Cell.

Coronary heart disease linked to problems with reasoning, vocabulary and verbal fluency

Coronary heart disease is associated with a worse performance in mental processes such as reasoning, vocabulary and verbal fluency, according to a study of 5837 middle-aged Whitehall civil servants. The study also found that the longer ago the heart disease had been diagnosed, the worse was the person's cognitive performance and this effect was particularly marked in men.

Luna awarded NIH grant for fullerene-based nanomedicines as allergy treatments

Luna Innovations Incorporated has announced the award of a $1.6 million Research Project Grant (R01) from the National Institutes of Health (NIH) to investigate the use of fullerene-based nanomedicines as a pathway to treat allergies and other inflammatory diseases.

New hope for infertile men - venous embolization

A minimally invasive treatment for a common cause of male infertility can significantly improve a couple's chances for pregnancy, according to a new study published in the August issue of Radiology. The study, conducted at the University of Bonn in Germany, also found that the level of sperm motility prior to treatment is a key predictor of success.

Discovery of cells for spinal-cord repair

A researcher at MIT's Picower Institute for Learning and Memory has pinpointed stem cells within the spinal cord that, if persuaded to differentiate into more healing cells and fewer scarring cells following an injury, may lead to a new, non-surgical treatment for debilitating spinal-cord injuries.

Discovery of new anatomical path through which the brain and spleen communicate

In a major step in understanding how the nervous system and the immune system interact, scientists at The Feinstein Institute for Medical Research have identified a new anatomical path through which the brain and the spleen communicate.

Study shows promising results in deep brain stimulation for treatment-resistant depression

New data from a study of patients with treatment-resistant depression who underwent deep brain stimulation (DBS) in the subcallosal cingulate region (SCG or Cg25) of the brain shows that this intervention is generally safe and provides significant improvement in patients as early as one month after treatment. The patients also experienced continued and sustained improvement over time.

Genetic mechanisms at play in blood cells important in Parkinson’s disease

What does the genetics of blood cells have to do with brain cells related to Parkinson's disease? From an unusual collaboration of neurologists and a pharmacologist comes the surprising answer: Genetic mechanisms at play in blood cells also control a gene and protein that cause Parkinson's disease.

Viral recombination another way HIV fools the immune system

When individuals infected with HIV become infected with a second strain of the virus, the two viral strains can exchange genetic information, creating a third, recombinant strain of the virus. It is known that the presence of multiple viral strains, called superinfection, frequently leads to a loss of immune control of viral levels.

Regular meals important for the health

It is obvious to most people that our health is affected by what we eat; now, however, scientists have shown that it is also a matter of how often we eat.

Too much sleep increases the risk of stroke in older women

Researchers in the United States have found that for older women too much or too little sleep increases their risk of a stroke.

Access to rheumatoid arthritis drugs 'curbed' for sufferers in the UK

Sufferers of rheumatoid arthritis in Britain have been warned that their access to a particularly effective class of drug will in future be limited.

Reduced dose anthracycline post-breast cancer surgery has no effect on outcome

Canadian researchers have discovered that there is a low risk of adverse effect from reducing post-op chemo by up to 25%, according to findings published in the online journal ecancermedicalscience.

Stem cell chicken and egg debate moves to unlikely arena: the testes

Logic says it has to be the niche. As air and water preceded life, so the niche, that hospitable environment that shelters adult stem cells in many tissues and provides factors necessary to keep them young and vital, must have emerged before its stem cell dependents.
