High throughput quantification of protein expression of cancer antigens in tissue microarray using quantum dot nanocrystals

In attempt to identify biological markers, or biomarkers, that can signal the presence of cancer and help oncologists determine the best course of therapy when cancer is present, teams of investigators are scouring stored tissue samples obtained from thousands of cancer patients.

Multispectral imaging of clinically relevant cellular targets in tonsil and lymphoid tissue using semiconductor quantum dots

When pathologists examine tissue samples in order to diagnose cancer of the lymphatic system, they examine the relative amounts of a group of proteins known as Cluster of Differentiation markers.

Scientists discover two proteins responsible for detecting sour tastes

A team led by Duke University Medical Center researchers has discovered two proteins in the taste buds on the surface of the tongue that are responsible for detecting sour tastes.

Gold nanorods injected into the bloodstream may be used to develop an advanced medical imaging tool

Researchers at Purdue University have taken a step toward developing a new type of ultra-sensitive medical imaging technique that works by shining a laser through the skin to detect tiny gold nanorods injected into the bloodstream.

New technology developed at Cornell University could make it just as easy to identify genes

A supermarket checkout computer can identify thousands of different items by scanning the tiny barcode printed on the package. New technology developed at Cornell University could make it just as easy to identify genes, pathogens, illegal drugs and other chemicals of interest by tagging them with color-coded probes made out of synthetic tree-shaped DNA.

Several minute intermediate stage in virus-cell fusion may represent a window of opportunity for drug development

To ignite a life-threatening infection in the body, a virus such as HIV invades body cells by first merging, or fusing, with the cell's outer membrane. Once inside the cell, the invading microbe's genetic material takes over, turning the 'host' cell into a factory to produce more copies of the virus, which then spill out to invade other cells in the body.

Technology for analyzing gene expression must be standardized

Technology for analyzing gene expression must be standardized among laboratories and across platforms around the world to support this age of human genome exploration, an Oregon Health & Science University researcher says.

Tiny fluorescent crystals barely visible to the human eye that could revolutionise cancer diagnosis

Scientists funded by the Association for International Cancer Research have developed tiny fluorescent crystals barely visible to the human eye that could revolutionise cancer diagnosis and treatment in a big way.

Scientists watch agents of brain-wasting diseases invade and move within brain cells

Scientists for the first time have watched agents of brain-wasting diseases, called transmissible spongiform encephalopathies (TSE), as they invade a nerve cell and then travel along wire-like circuits to points of contact with other cells.

DNA sequencing made portable and faster by "colour-blind" technology

Researchers at Baylor College of Medicine (BCM) and Rice University have developed a"colour-blind" method of fluorescence detection which could open new doors that would take DNA sequencing to the patient's bedside, the doctor's office and even the scene of a crime or a battlefield.

Unique technology with the potential to test for hundreds of diseases, cancers and genes in one, cheap, test

Queensland, Australia PhD student Angus Johnston has invented a unique technology with the potential to test for hundreds of diseases, cancers and genes in one, cheap, test. He hopes that within five years the technology will be available in a desktop unit for less than AU$30,000.

New fluorescent dye technique may provide new insight into how cancerous tumors begin and grow

A technique developed by University of California, San Diego biologists, which uses bright fluorescent dyes to reveal the activity of genes in individual cells of an organism, promises to be a boon to developmental biologists, and may provide new insight into how cancerous tumors begin and grow.
