Intra-arterial technique of stem cell transplantation may enhance functional recovery from TBI

Experiments in brain-injured rats show that stem cells injected via the carotid artery travel directly to the brain, where they greatly enhance functional recovery, reports a study in the February issue of Neurosurgery, official journal of the Congress of Neurological Surgeons. The journal is published by Lippincott Williams & Wilkins, a part of Wolters Kluwer Health.

Researchers use liquid laser to diagnose genetic mutations linked with cancer

Using a liquid laser, University of Michigan researchers have developed a better way to detect the slight genetic mutations that might predispose a person to a particular type of cancer or other diseases.

Fluorescence microscopy reveals 3-D picture of myoV's transport capacity

A new study in the Journal of General Physiology uses state-of-the-art fluorescence microscopy to provide a striking 3-D picture of how class V myosins (myoV) "walk" along their actin track.

ASI's GenASIs for detection of chromosomal aberrations in bladder cancer receives FDA approval

Applied Spectral Imaging (ASI) announced today that ASI's GenASIs Scan & Analysis, SpotScan used for the detection of chromosomal aberrations in bladder cancer has been cleared by the United States Food and Drug Administration (FDA) for marketing in the US.

Researchers identify possible cause for loss of tumor suppressor genes

Researchers at Queen's University in Kingston, Canada have identified a possible cause for the loss of a tumour suppressor gene (known as PTEN) that can lead to the development of more aggressive forms of prostate cancer.

WSU professors receive NSF grant to develop math model of liver metabolism

Predicting problems in one of the body's most complex organs soon may become easier because of work being done by Wayne State University researchers.

A reliable way to replicate α-synuclein aggregation on cell membranes in Parkinson's disease patients

The accumulation of α-synuclein, a small, negatively charged protein, in neural cells, is one of the hallmarks of Parkinson's disease. It has been suggested that oligomeric α-synuclein causes membranes to become permeable, or to form channels on the outer cell membrane.

New imaging probes can non-invasively detect breast cancer lymph node metastasis

Using two cell surface markers found to be highly expressed in breast cancer lymph node metastasis, researchers at Moffitt Cancer Center, working with colleagues at other institutions, have developed targeted, fluorescent molecular imaging probes that can non-invasively detect breast cancer lymph node metastasis.

Scientists discover how sense of touch is wired in skin and nervous system

Neuroscientists at the Johns Hopkins University School of Medicine have discovered how the sense of touch is wired in the skin and nervous system. The new findings, published Dec. 22 in Cell, open new doors for understanding how the brain collects and processes information from hairy skin.

Novel nanosensors can lead to fewer experiments on animals

Countless mice, rats and rabbits die every year in the name of science - and the situation is getting worse. While German laboratories used some 2.41 million animals for scientific research in 2005, by 2009 this number had grown to 2.79 million. One third were destined for fundamental biology research, and the majority were used for researching diseases and developing medical compounds and devices.

ORMOSIL nanoparticles show promise as potential drug delivery vehicle

In the images of fruit flies, clusters of neurons are all lit up, forming a brightly glowing network of highways within the brain. It's exactly what University at Buffalo researcher Shermali Gunawardena was hoping to see: It meant that ORMOSIL, a novel class of nanoparticles, had successfully penetrated the insects' brains. And even after long-term exposure, the cells and the flies themselves remained unharmed.

DHA plays an essential role in creating healthy sperm

Who knew that male fertility depends on sperm-cell architecture? A University of Illinois study reports that a certain omega-3 fatty acid is necessary to construct the arch that turns a round, immature sperm cell into a pointy-headed super swimmer with an extra long tail.

Scientists map neurons that process different kinds of visual information

There's a 3-D world in our brains. It's a landscape that mimics the outside world, where the objects we see exist as collections of neural circuits and electrical impulses.

Biologists develop radar to track ADAR's RNA editing activity in neurons

To track what they can't see, pilots look to the green glow of the radar screen. Now biologists monitoring gene expression, individual variation, and disease have a glowing green indicator of their own: Brown University biologists have developed a "radar" for tracking ADAR, a crucial enzyme for editing RNA in the nervous system.

Reverse spectroscopy eliminates background noise and cleans up images

Optical techniques enable us to examine single molecules, but do we really understand what we are seeing? After all, the fuzziness caused by effects such as light interference makes these images very difficult to interpret.

Researchers identify molecules that can stimulate heart muscle regeneration

Damaged heart tissue is not known for having much inherent capacity for repair. But now, scientists are closing in on signals that may be able to coax the heart into producing replacement cardiac muscle cells. Using a zebrafish model system, researchers have identified a family of molecules that can stimulate stem cells to develop into beating heart muscle cells.

New way to awaken paternal Ube3a allele linked with Angelman syndrome

Results of a new study from the University of North Carolina at Chapel Hill may help pave the way to a treatment for a neurogenetic disorder often misdiagnosed as cerebral palsy or autism.
