Study develops new approaches for sorting out complexities of cancer cells

New drugs that specifically target the mutated genes responsible for cancer growth have shown great success in extending the lives of patients, with far fewer side effects than conventional anti-cancer therapies. Unfortunately, many patients become resistant to these drugs due to secondary mutations.

Study: Surgeon enthusiasm linked to high spinal procedure rates

Surgeons in some areas are more likely to recommend surgery for low back problems—and those differences in "surgeon enthusiasm" are a major factor driving regional variations in spinal surgery rates, suggests a study in the March 14 issue of Spine. The journal is published by Lippincott Williams & Wilkins, a part of Wolters Kluwer Health.

Quantum dots allow stem cell therapy monitoring for brain injury

A new technique using "quantum dots" produced through nanotechnology is a promising approach to monitoring the effects of stem cell therapies for stroke and other types of brain damage, reports the April issue of Neurosurgery, official journal of the Congress of Neurological Surgeons.

Imaging with voltage-sensitive dye captures real-time brain dynamics

The dye incorporates in the brain cells' membrane and changes fluorescence whenever these receive or send electrical signals. Hence, high resolution camera systems allow to simultaneously capture activities of millions of nerve cells across several square millimeters across the brain.

Brain's pleasure and reward circuitry gets a big boost after a sleepless night

A sleepless night can make us cranky and moody. But a lesser known side effect of sleep deprivation is short-term euphoria, which can potentially lead to poor judgment and addictive behavior, according to new research from the University of California, Berkeley.

Cell receptor recycling mechanism discovery opens up new class of therapeutic targets

Prof. Manojkumar Puthenveedu of Carnegie Mellon University studies the mechanisms by which membrane trafficking controls and co-ordinates the complex signalling pathways in the brain. Despite the fact that almost all diseases can be traced to a defect in how cells respond to signals, little is known about how signalling pathways are maintained in normal cells and the changes that occur in abnormal conditions.

Contrast agent for tumor diagnostics

X-rays are not the only way: visible and especially infrared light can also be used to image human tissue. The effectiveness of optical imaging processes can be significantly improved with suitable dyes used as contrast agents. In the journal Angewandte Chemie, a team led by Wenbin Lin at the University of North Carolina (Chapel Hill, USA) has now introduced a novel contrast agent that marks tumor cells in vitro. The dye is a phosphorescent ruthenium complex incorporated into nanoparticles of a metal–organic coordination polymer, which allows an extraordinarily high level of dye loading.

New research on brain plasticity may delay onset of Alzheimer's disease

The human brain loses 5 to 10% of its weight between the ages of 20 and 90 years old. While some cells are lost, the brain is equipped with two compensatory mechanisms: plasticity and redundancy.
