Doctors at the Duke University School of Medicine have tested a new injectable agent that causes cancer cells in a tumor to fluoresce, potentially increasing a surgeon’s ability to locate and remove all of a cancerous tumor on the first attempt. The imaging technology was developed through collaboration with scientists at Duke, the Massachusetts Institute of Technology (MIT) and Lumicell Inc.
Antibodies combat viruses and bacteria. They also attach themselves to cancer cells – in a typical, characteristic way. Fraunhofer scientists are using this property to detect cancer cells in tissue samples. Such rapid tests can already be applied by surgeons during operations – within a few minutes and without expensive equipment.
Scientists have shown for the first time that an enzyme crucial to keeping our immune system healthy “surfs” along the strands of DNA inside our cells. The researchers used extremely powerful microscopy to watch how the enzyme AID (activation-induced deoxycytidine deaminase) moves around and interacts with other molecules.
Bladder cancer is associated with high recurrence rates, necessitating prolonged surveillance and repeated treatments. As a result, it is one of the most challenging and costly of all solid tumours to manage. Although most patients present at an early stage with non-muscle-invasive bladder cancer (NMIBC), between 13% and 61% will experience recurrence within 1 year of initial transurethral…
A team of scientists at the Children’s Research Institute at UT Southwestern (CRI) has become the first to use a tissue-clearing technique to localize a rare stem cell population, in the process cracking open a black box containing detailed information about where blood-forming stem cells are located and how they are maintained. The findings provide a significant advance toward understanding…
Automated image analysis shows significant potential within histopathology to help identify novel and subtle prognostic features. UK expert Dr Peter Caie also believes such image analysis can turn aspects of histopathology from a traditionally semi-quantitative field into a fully quantifiable and standardised science. However, he also points out that challenges remain before the full potential is…

The view across the Atlantic – it fills Professor Fabian Kiessling, Chair of Experimental Molecular Imaging at the RWTH Aachen (Rhine-Westphalia Institute of Technology Aachen), with optimism. The USA offers more opportunities for molecular imaging. Only recently, new tracers for Alzheimer’s were accepted as reimbursable in some centres, whilst the development of new diagnostics in Europe…
Gideon Ho, CEO and co-founder of Singapore-based HistoIndex is confident: ‘After a biopsy a patient waits in a hospital bed, but now, instead of waiting a couple days until doctors know how to treat this patient, we can deliver results while the patient is still in the hospital.’ Report: John Brosky

Catastrophes draw people closer, as demonstrated by the development of the new high-end ultrasound scanner Aplio 500 from Toshiba. The clinical evaluation period took place during the tsunami and the nuclear catastrophe in Fukusima. Professor Thomas Fischer at the Radiological Institute, Charité Clinic in Berlin, was impressed by the enormous commitment shown by the Japanese firm’s engineers…
Breast cancer is the most common form of cancer in women. Evaluation of the axillary lymph nodes is essential to insure complete cancer removal. Fluorescence imaging instead of radioisotopes is an innovative method for sentinel lymph node detection.
A new technique to aid the early detection and diagnosis of inflammatory bowel disease has been developed by UK and Germans researchers. The Confocal Laser Endomicroscope (CLE) contains a powerful microscope that allows clinicians to view bacteria in the intestine that are thought to trigger bowel diseases such as Crohn’s and ulcerative colitis.
It sounds like an idea plucked from the realms of science fiction writing. But in this case, there is nothing fictional about it. Scientists in Yorkshire have developed a process that uses the luminous cells from jellyfish to diagnose cancers deep within the human body.
Molecular imaging, the discipline that unites molecular biology and in vivo imaging technologies to assess biological activity in the body, promises to open up ‘…an entire new universe,’ declared Dr Ralph Weissleder, of the Centre for Molecular Imaging Research at Massachusetts General Hospital, USA, in the journal Radiology. That was just one decade ago. And he was right. It has indeed…

Molecular imaging, a new science that emerged from molecular biology, is unlike traditional imaging. Whilst the latter can, for example, show the differences in proton density or water content on MRI, molecular imaging uses biomarkers (probes) that interact selectively with molecules within an area and then generate the image according to fine molecular alterations occurring inside (e.g. within a…
The detection and documentation of low light fluorescence signals in live cell experiments is a particular challenge for digital cameras. To meet this demand, Leica Microsystems adds the new Leica DFC345 FX to its portfolio of powerful digital cameras. In addition to combining high sensitivity with high resolution, this new camera features a fast image capture rate and a broad dynamic range,…
