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.

Optical imaging can visualize cultured cancer cells' response to particular drug

Many cancer therapies target specific proteins that proliferate on the outside of some cancer cells, but the therapies are imperfect and the cancer does not always respond. Since it is beneficial for doctors to know as soon as possible how a cancer is affected by treatment, researchers from Vanderbilt University are striving to design tests that assess treatment response rapidly, accurately, and cost-effectively.

PRI now offers latest surgical robotics for patients with kidney tumors

The Porter Robotics Institute (PRI) now offers the latest in advanced surgical robotics available to patients with kidney tumors, allowing surgeons the ability to remove just a portion of the kidney.

New substance can replace nucleoside thymidine in DNA biosynthesis

Interactions of biological macromolecules are the central bases of living systems. Biological macromolecules are synthesized in living cells by linking many small molecules together. Naturally occurring macromolecules include genetic materials (DNA) and proteins. A detailed understanding of the synthesis of these macromolecules in whole animals is a basic requirement for understanding biological systems, and for the development of new therapeutic strategies.

Onyx announces data from three carfilzomib studies on RRMM

Onyx Pharmaceuticals, Inc. today announced summaries of three poster presentations of single-agent carfilzomib, a next generation proteasome inhibitor, in patients with relapsed and/or refractory multiple myeloma at the 53rd American Society of Hematology (ASH) Annual Meeting in San Diego, CA.

Biochip can quickly predict blood poisoning

Is the patient suffering from blood poisoning? To answer this question, the doctor draws a blood sample and sends it to a central laboratory for testing. This takes up valuable time, which could cost the patient his life. In future, physicians will be able to analyze blood there and then and have the results within twenty minutes.

Study explains molecular basis for cherubism disease

The Samuel Lunenfeld Research Institute's Drs. Frank Sicheri, Tony Pawson and Sebastian Guettler, in collaboration with Dr. Robert Rottapel at the Ontario Cancer Institute, have uncovered the detailed architecture of a crucial component of Tankyrase, a protein linked to the bone development disorder cherubism and involved in a myriad of cellular processes.

Researchers reveal contribution of telomerase in controlling genetic code integrity

Researchers have revealed how a molecule called telomerase contributes to the control of the integrity of our genetic code, and when it is involved in the deregulation of the code, its important role in the development of cancer.

Lawson researchers exploit hunger hormone to identify prostate cancer

Non-invasive imaging detects prostate cancer earlier than ever before, but can't accurately distinguish between malignant and benign disease. According to Lawson Health Research Institute's Drs. John Lewis and Len Luyt, a new molecular imaging probe could be the answer.

Study reveals previously unseen details of SBP8a anthrax bacteriophage

A new study has shown previously unseen details of an anthrax bacteriophage - a virus that infects anthrax bacteria - revealing for the first time how it infects its host, and providing an initial blueprint for how the phage might someday be modified into a tool for the detection and destruction of anthrax and other potential bioterror agents.
