UCLA findings could lead to enhanced health supplements, progress on Parkinson's

The discovery by UCLA biochemists of a new method for preventing oxidation in the essential fatty acids of cell membranes could lead to a new class of more effective nutritional supplements and potentially help combat neurodegenerative disorders such as Parkinson's disease and perhaps Alzheimer's.

Study raises questions about therapeutic use of botulinum toxin A

A new study by researchers at the Faculty of Kinesiology, University of Calgary, is raising questions about the therapeutic use of botulinum toxin A.

Lipids react and change to bacterial stimulus, trigger cell's immune response

For the first time, scientists have described not only the identities and quantities of fat species in a living mammalian cell in this case, a mouse macrophage or white blood cell but they also report how these lipids react and change over time to a bacterial stimulus triggering the cell's immune response.

MRS imaging technique may help diagnose chronic traumatic encephalopathy

In a study of ex-pro athletes, researchers found that a specialized imaging technique called magnetic resonance spectroscopy (MRS) may help diagnose chronic traumatic encephalopathy (CTE), a disorder caused by repetitive head trauma that currently can only be definitively diagnosed at autopsy. Results of the study were presented today at the annual meeting of the Radiological Society of North America (RSNA).

Rush University enrolls first U.S. patient in international clinical trial for melanoma

Rush University Medical Center has just enrolled the first U.S. patient in an international clinical trial testing a novel drug to treat certain kinds of melanoma, a deadly skin cancer that in its advanced stages currently has few effective treatments.

Universal microfluidics connector could find broad use in compact medical devices

Biomedical engineers at UC Davis have developed a plug-in interface for the microfluidic chips that will form the basis of the next generation of compact medical devices. They hope that the "fit to flow" interface will become as ubiquitous as the USB interface for computer peripherals.

NIH awards $6.7M to establish Membrane Protein Structural Biology Consortium

Dr. Michael G. Malkowski, Hauptman-Woodward senior research scientist, has received a $6.7 million grant from the National Institutes of Health in support of his work to establish the Membrane Protein Structural Biology Consortium (mpsbc.org) as one of nine centers in the United States responsible for determining membrane protein structures within a larger NIH biology-based initiative.

Researchers explain molecular mechanism that induces HER2+ tumours to ignore cell signals

About 30% of breast cancer patients have tumours that show rapid growth and invasion through the body. A common denominator in all of these cases is the presence of a large number of Her2 proteins in tumour cellular membranes. Consequently, these aggressive tumours are referred to as HER2+. Scientists working in the Metastasis Laboratory (MetLab) at IRB Barcelona headed by ICREA researcher Roger Gomis, have described the molecular mechanism that induces HER2+ tumours to ignore the signals that protect cells from excessive growth.

Researchers discover cells’ response to sour tastes

This Thanksgiving, when you bite into the cranberry sauce and the tartness smacks your tongue as hard as that snide comment from your sister, consider the power of sour. Neurobiology researchers at the University of Southern California have made a surprising discovery about how some cells respond to sour tastes.

Bacterial study confirms TLR2 signaling vital for activating human airway epithelial cells

Researchers from the Boston University School of Medicine (BUSM) have demonstrated that commensal species of the genus Neisseriae are low inducers of human airway epithelial cell responses as compared to the pathogenic species.

DFG announces establishment of eleven new Collaborative Research Centres

The Deutsche Forschungsgemeinschaft (DFG, German Research Foundation) will establish eleven new Collaborative Research Centres (CRC) as of 1 January 2011. This decision was made recently by the responsible Grants Committee at its autumn meeting in Bonn. The new CRCs will receive a total of - 94.4 million (including a 20 percent programme allowance for indirect project costs) for an initial funding period of four years.

African American cigarette smokers at higher risk of rheumatoid arthritis

A new study determined that African Americans who smoke cigarettes have a higher risk of developing rheumatoid arthritis (RA). RA risk is more pronounced among individuals positive for the HLA-DRB1 shared epitope, a genetic risk factor for RA. Findings from this study—the largest to date examining the impact of smoking on RA risk in an African American population—are available in the December issue of Arthritis & Rheumatism, a journal published by Wiley-Blackwell on behalf of the American College of Rheumatology (ACR).

GFAP levels predict brain injury, death in critically ill children on ECMO

Johns Hopkins Children's Center scientists have discovered that high blood levels of a protein commonly found in the central nervous system can predict brain injury and death in critically ill children on a form of life support called extra-corporeal membrane oxygenation or ECMO.

Researchers develop three-dimensional cancer cell from normal human tissue in culture dish

Researchers at the Stanford University School of Medicine have successfully transformed normal human tissue into three-dimensional cancers in a tissue culture dish for the first time. Watching how the cells behave as they divide and invade surrounding tissue will help physicians better understand how human cancers act in the body. The new technique also provides a way to quickly and cheaply test anti-cancer drugs without requiring laboratory animals.

Study sheds light on poorly understood aspect of interaction of HIV with natural killer cells

Natural killer cells are major weapons in the body's immune system. They keep the body healthy by knocking off tumors and cells infected with viruses, bombarding them with tiny lethal pellets. But natural killer cells are powerless against HIV, a fact that has bedeviled science for over 20 years.

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.

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.

New direct labeling system for oocytes, embryos

Researchers from the Department of Cell Biology, Physiology and Immunology at Universitat Autònoma de Barcelona (UAB), in collaboration with researchers from the Institute of Microelectronics of Barcelona (IMB-CNM) of the Spanish National Research Council (CSIC), have developed an identification system for oocytes and embryos in which each can be individually tagged using silicone barcodes.

Anti-cancer drug smuggled using a nanocarrier past protective blood-brain barrier into brain tumours

Scientists in Germany have developed a way of smuggling an anti-cancer drug past the protective blood-brain barrier and into brain tumours and metastases using a nanocarrier - a tiny capsule specially designed to pass through cell membranes and deliver its anti-cancer drug to the cancer cell.

VX-770 drug candidate improves lung function in people with cystic fibrosis

In a study published in this week's New England Journal of Medicine, treatment with a new drug candidate known as VX-770 resulted in improvements in lung function and markers of disease in a Phase 2 clinical trial of 39 people with cystic fibrosis (CF). There were no discontinuations due to adverse events in the study, and the frequency of adverse events was similar across the study groups.
