Researchers uncover protein structural clues associated to PD

Researchers at the Keck School of Medicine of the University of Southern California (USC) have uncovered structural clues about the protein linked to Parkinson's disease (PD), which ultimately could lead to finding a cure for the degenerative neurological disorder.

Ventana Medical receives FDA approval for new breast cancer genetic test

The U.S. Food and Drug Administration today approved a new genetic test that will help health care professionals determine if women with breast cancer are HER2-positive and, therefore, candidates for Herceptin, a commonly used breast cancer treatment.

Synaptophysin controls replacement of vesicles

A University of Wisconsin-Madison research team has solved a 25-year mystery that may lead to better treatments for people with learning deficits and mental retardation.

Novel FRET biosensor allows measurement of intraorganellar glutathione potentials in living cells

In work published in the June 2011 issue of Experimental Biology and Medicine, Kolossov, Spring and their co-investigators - a multidisciplinary team within the Institute for Genomic Biology at the University of Illinois - have transferred the concept of redox-sensitive Green Fluorescent Proteins (GFPs) to a quantitative F-rster resonance energy transfer (FRET) imaging platform.

Super microscopes help scientists identify exact molecular 'switch' that spurs T-cells into action

Using the only microscope of its kind in Australia, medical scientists have been able for the first time to see the inner workings of T-cells, the front-line troops that alert our immune system to go on the defensive against germs and other invaders in our bloodstream.

New understanding of muscle growth and repair

Revealing another part of the story of muscle development, Johns Hopkins researchers have shown how the cytoskeleton from one muscle cell builds finger-like projections that invade into another muscle cell’s territory, eventually forcing the cells to combine.

Dendritic cells secrete signal molecule that contributes to pathogenesis of atherosclerosis

Atherosclerosis is the most common cause of cardiovascular disease, and results from chronic inflammation of arterial vessel walls. An international collaboration led by Professor Christian Weber of Ludwig-Maximilians-Universität (LMU) in Munich and Privatdozentin Alma Zernecke of Würzburg University now shows that dendritic cells stimulate this process by derailing a mechanism that normally acts as a brake on immune reactions.

MreB protein molecules assemble into larger units in bacterial cell wall

Almost all bacteria owe their structure to an outer cell wall that interacts closely with the supporting MreB protein inside the cell. As scientists at the Max Planck Institute for Biochemistry and at the French INRA now show, MreB molecules assemble into larger units, but not - as previously believed - into continuous helical structures.

Insight into understanding of normal muscle growth

Revealing another part of the story of muscle development, Johns Hopkins researchers have shown how the cytoskeleton from one muscle cell builds finger-like projections that invade into another muscle cell's territory, eventually forcing the cells to combine.

New imaging method using fluorescent nanotubes can peer clearly into living mouse's innards

Developing drugs to combat or cure human disease often involves a phase of testing with mice, so being able to peer clearly into a living mouse's innards has real value.

UBC scientists to initiate $4.7M pan-Canadian clinical trial in oral squamous cell cancers

Researchers from the University of British Columbia's Faculties of Medicine, Science and Dentistry are leading a $4.7-million pan-Canadian clinical trial aimed at improving outcomes for patients undergoing surgery for oral squamous cell cancers.

Pan-Canadian surgical study offers new hope for patients with early-stage oral cancer

Currently, about 30 per cent of patients who receive oral surgery have their cancer recur. But a new, Canada-wide surgical trial using a new approach to remove tumours and pre-cancerous cells from the mouths of those diagnosed with early-stage oral cancer offers new hope for patients.

Insight into new prion formation

Unlocking the mechanisms that cause neurodegenerative prion diseases may require a genetic key, suggest new findings reported by University of Illinois at Chicago distinguished professor of biological sciences Susan Liebman.

Nanoscopic findings may lead to new experimental methods for early multiple sclerosis diagnosis

Laboratory studies by chemical engineers at UC Santa Barbara may lead to new experimental methods for early detection and diagnosis -- and to possible treatments -- for pathological tissues that are precursors to multiple sclerosis and similar diseases.

New technique can detect minute traces of tumoral DNA in biological fluids

It will perhaps be possible, in the near future, to detect cancer by a simple blood or urine test. In fact, biologists from CNRS, Inserm, Paris Descartes and Strasbourg universities have developed a technique capable of detecting minute traces of tumoral DNA present in the biological fluids of patients suffering from cancer.

Blood stored in banks may undergo changes and damage

New research provides evidence for significant differences between new and old red blood cells used for transfusions and could provide a cheap, rapid and effective way to monitor the quality of blood supplies.

Monitoring adherence to mandatory hand-washing protocols can help stop outbreaks of C. diff bacteria

Just like intelligence agents watching for the real terrorists threatening to attack, monitoring healthcare worker adherence to mandatory hand-washing protocols via hand-washing squads in hospitals can go a long way to stop outbreaks of the opportunistic C. diff bacteria, says Irena Kenneley, an infection prevention and control expert and assistant professor of nursing from the Frances Payne Bolton School of Nursing at Case Western Reserve University.

Swedish adds new virtual reality training simulator to help surgeons practice on robotic-assisted system

As one of the first medical centers in the Northwest to perform robotic-assisted surgery, Swedish is home to the fastest growing, most comprehensive and experienced robotic-assisted surgical program in the region. Swedish established the multidisciplinary, robotic-assisted surgical program in 2005 and has since performed more than 3,400 robotic-assisted surgeries -- more than any other program in the region.

Common tiny tropical fish plays a key role in new model for Cushing disease

A common, tiny tropical fish plays a key role in a new model for Cushing disease, giving researchers a powerful tool to conduct extensive searches for effective treatments for this serious hormonal disorder, testing up to 300 drugs weekly.
