Study refocuses on rare group of neutralizing antibodies against HIV

Although people infected with HIV produce many antibodies against the protein encapsulating the virus, most of these antibodies are strangely ineffective at fighting the disease. A new study suggests why some of the most common of these antibodies don't work: they target the protein in a form it takes after the virus has already invaded the cell, when it's too late, report researchers at Children's Hospital Boston and their colleagues.

Abnormal levels of circulating auto-antibodies found in blood of COPD patients

Moderate to severe chronic obstructive pulmonary disease (COPD) may be an auto-immunity problem, according to researchers in Spain, who studied the presence of auto-antibodies in patients with COPD and compared them to levels of control subjects. They found that a significant number of patients with COPD had significant levels of auto-antibodies circulating in their blood, about 5 to 10 times the level in controls.

High CRP and low protein albumin levels associated with increased risk of death after PEG-operations

The combination of high CRP and low levels of the protein albumin in the blood, is associated with an increased risk of death after a PEG-operation; implantation of a nutritional catheter into the stomach through the abdominal wall. This was shown in a new study from the Swedish medical university Karolinska Institutet, published in the scientific journal Gastrointestinal Endoscopy. Of the PEG patients in the study that showed both current indicators, 20 percent died within 30 days.

Platelet Rich Plasma Therapy reduces pain and improves function in knee osteoarthritis patients

The first American study that positions Platelet Rich Plasma Therapy (PRP) as a viable means in managing knee osteoarthritis, appeared today in the December issue of the American Journal of Physical Medicine & Rehabilitation (AJPMR). The study, authored by Dr. Steven Sampson of the Orthohealing Center in Los Angeles, details the account of 14 patients with primary and secondary knee osteoarthritis receiving three platelet-rich plasma injections in the affected knee at 4-week intervals with one year follow up.

Discovery could provide new approaches to treat metabolic disorders

Scientists from the Florida campus of The Scripps Research Institute have identified a novel synthetic activator of a pair of proteins that belong to a protein family playing key roles in human metabolism and immune function. The discovery could provide new and potentially more effective therapeutic approaches to diseases ranging from diabetes to osteoporosis.

Researchers develop medical model for regenerating bladders using stem cells

Researchers in the United States have developed a medical model for regenerating bladders using stem cells harvested from a patient's own bone marrow. The research, published in STEM CELLS, is especially relevant for paediatric patients suffering from abnormally developed bladders, but also represents another step towards new organ replacement therapies.

Reprogrammed amniotic fluid cells can generate iPS cells

Reprogrammed amniotic fluid cells can generate all types of body cells. High hopes rest on stem cells: one day, they may be used to treat many diseases. To date, embryos are the main source of these cells, but this raises ethical problems. Scientists at the Max Planck Institute for Molecular Genetics in Berlin have now managed to convert amniotic fluid cells into pluripotent stem cells.

FDA-approved anti-parasite drug blocks Wnt signaling pathway in colon cancer

An old pinworm medicine is a new lead in the search for compounds that block a signaling pathway implicated in colon cancer. The findings, reported by Vanderbilt University Medical Center researchers in the November issue of Nature Chemical Biology, suggest a fresh approach for developing therapeutics that target the pathway.

Cold Spring releases new series of laboratory manuals

Sophisticated techniques that permit the visualization of dynamic processes in cells, tissues, and organ systems at extraordinary levels of resolution have become tremendously valuable in biological research. However, finding the right imaging method and optimizing it for data collection can be a daunting process, even for an established imaging laboratory. To fill this need, a new series of laboratory manuals has been developed by Cold Spring Harbor Laboratory Press. The first volume in this series, Imaging: A Laboratory Manual, has just been released.

Researchers document novel form of splicing in nerve cell cytoplasm

Cells have their own version of the cut-and-paste editing function called splicing. Researchers at the University of Pennsylvania School of Medicine have documented a novel form of splicing in the cytoplasm of a nerve cell, which dictates a special form of a potassium channel protein in the outer membrane.
