New technique to view labeled tumor cells in 'real' time

A breakthrough technique that allows scientists to view individually-labeled tumor cells as they move about in real time in a live mouse may enable scientists to develop microenvironment-specific drugs against cancer, researchers report at the American Society for Cell Biology (ASCB) 48th Annual Meeting, Dec. 13-17, 2008 in San Francisco.

Mathematical models of adaptive immunity

More than five million people die every year from infectious diseases, despite the availability of numerous antibiotics and vaccines. The discovery of penicillin to treat bacterial infections, along with the development of vaccines for previously incurable virus diseases such as polio and smallpox, achieved great reductions in mortality during the mid-20th century.

Discovery of protein that may cause breast cancer to spread

In an important finding published online in Developmental Cell , researchers at Albert Einstein College of Medicine of Yeshiva University, along with collaborators at Massachusetts Institute of Technology, have identified a protein likely responsible for causing breast cancer to spread.

New method of viewing cancer cells shows how breast cancer spreads

In a breakthrough study appearing in advance online publication of Nature Methods, researchers at Albert Einstein College of Medicine of Yeshiva University describe for the first time a method of viewing individual breast cancer cells for several days at a time.

Second annual Johns Hopkins NanoBio Symposium to focus on cancer

An estimated 600 experts on nanobiotechnology-a science that develops tools and machinery at the scale of one-billionth of a meter-are expected to attend the second annual Johns Hopkins NanoBio Symposium, May 1-2, 2008.

Real-time imaging device may improve surgery for congenital colon disease

Researchers at Cedars-Sinai Medical Center are developing a spectral imaging system that could result in shorter operating times for infants undergoing surgery for Hirschsprung's disease, according to a mouse study reported in the Journal of Biophotonics.

New detection techniques for pancreatic cancer

Using novel light-scattering techniques, researchers have found the first evidence that early stage pancreatic cancer causes subtle changes in part of the small intestine.

Drug delivery system that consists of nanocrystals of a hydrophobic drug

The problem of efficiently delivering drugs, especially those that are hydrophobic or water-repellant, to tumors or other disease sites has long challenged scientists to develop innovative delivery systems that keep these drugs intact until reaching their targets.

Scientists tackle huntingtin protein

McMaster scientists are very close to defining small molecule drugs that should be able to redirect the huntingtin protein from accumulating in the wrong place within brain cells, which could potentially translate to a therapy for Huntington's Disease (HD).

New cancer detection method

University of Florida researchers say they are a step closer to a technique to easily detect a wide variety of cancers before symptoms become apparent.

Fluorescence spectroscopy able to detect the presence of inflammatory cells that are associated with critical atherosclerotic plaques

Because atherosclerotic plaque typically builds up without symptoms and leads to more than 1 million deaths in America each year, the search is on to develop early detection devices that will enable physicians to offer treatment before the disease progresses to advanced stages.

Fluorescence device to diagnose atherosclerosis and tumors

In a presentation at the Conference on Lasers and Electro-Optics (CLEO), researchers from Cedars-Sinai Medical Center's Biophotonics Research and Technology Development Laboratory described recent progress on a device that stimulates, collects and measures light emissions from body tissues to diagnose critical atherosclerotic plaques (vulnerable plaques) and aggressive brain tumors.

Miniature spectroscopic instruments and software to look at changes that occur within the cells and tissue of the brain

When molecules in cells are stimulated by light, they respond by becoming excited and re-emitting light of varying colors (fluorescence) that can be captured and measured by highly sensitive optical equipment.
