Rice researcher extracts natural scaffold for tissue growth It frequently happens in science that what you throw away turns out to be most valuable. It happened to Deepak Nagrath, but not for long. The Rice assistant professor in chemical and biomolecular engineering was looking for ways to grow cells in a scaffold, and he discarded the sticky substance secreted by the cells. "I thought it was contamination, so I threw the plates away," said Nagrath, then a research associate at Harvard...

Researchers at Washington University School of Medicine in St. Louis have peered deep into the eye of the chicken and found a masterpiece of biological design. Scientists mapped five types of light receptors in the chicken's eye. They discovered the receptors were laid out in interwoven mosaics that maximized the chicken's ability to see many colors in any given part of the retina, the light-sensing structure at the back of the eye. "Based on this analysis, birds have clearly one-upped us in...

The cutting edge science of how vision works and how we may be able to prevent, repair or restore lost sight in future will be explored at an international scientific meeting in Sydney next week. The Australian Neuroscience Society Satellite Meeting 2010: "From Photoreceptors to Behaviour" is being held at the Save Sight Institute, 8 Macquarie St, Sydney on January 29 and 30, 2010. Among the highlights of the meeting:"¢ Professor Zhou-Hua Pan of Wayne State University, USA, will describe...

Determining what triggers the death of retinal cells, called photoreceptors, could hold the key to stopping blinding disorders caused by a wide range of eye diseases, Yale School of Medicine researchers report in the November journal Investigative Ophthalmology & Visual Science. Several blinding disorders are known to cause the breakdown of photoreceptors. Caroline Zeiss, associate professor of comparative medicine and ophthalmology at Yale School of Medicine, and her colleagues sought to...

A German-Hungarian medical team says it has developed a mass spectrometric ionization technique that can analyze vital tissues during surgical procedures. The researchers, led by Zoltan Takats of Justus-Liebig University in Giessen, Germany, said the technique might make it possible to distinguish between malignant tumor cells and surrounding healthy tissue in real time during cancer surgery. Until now, precise histological examination of the removed tissue has occurred after tumor surgery...

Coupling electrosurgery with mass spectrometry for real-time identification of tumor tissues Instead of the classic scalpel, surgeons can also operate with an electroscalpel. A significant advantage to this technique is that while a cut is being made, blood vessels are closed off and hemorrhaging eliminated. Now another advantage may be added as well: a German-Hungarian research team has developed a mass-spectrometry-based technique by which tissues can be analyzed during a surgical...

Researchers led by Dr. Soheil Dadras at the Stanford University Medical Center have developed a novel methodology to extract microRNAs from cancer tissues. The related report by Ma et al, "Profiling and discovery of novel miRNAs from formalin-fixed paraffin-embedded melanoma and nodal specimens," appears in the September 2009 issue of the Journal of Molecular Diagnostics.Cancer tissues from patients are often stored by a method that involves formalin fixation and paraffin embedding to retain...

Researchers from the John Hopkins School of Medicine have discovered a new type of cell used for vision in fish.The report, which appears in the journal Nature, explains how researchers found a retinal horizontal cell that senses light and contributes to vision."This is mind-boggling," says King-Wai Yau, Ph.D., a professor of neuroscience at John Hopkins."For more than 100 years, it's been known that rod cells and cone cells are responsible for sensing light, and therefore, vision," says Yau....

A new study by scientists at the University of Iowa shows why muscle membranes don't rupture when healthy people exercise.The findings shed light on a mechanism that appears to protect cells from mechanical stress. The study, which appears online July 20-24 in Proceedings of the National Academy of Sciences (PNAS) Early Edition, also helps explain why muscle damage is so severe when this mechanism is disrupted, which occurs in certain congenital and limb-girdle muscular...
