Genetic profile, not clinical appearance, to determine tumor treatment
... seemingly adequate treatment. A new generation of ultrasensitive diagnostics has highlighted the problem of subcutaneous foci of residual tumors that may remain at the operative site, or be disseminated throughout the body. These approaches have also revealed that the extent of spread of a precancerous patch is of...Nomadic outposts of transplanted stem cells tracked in Stanford study
...m luciferase isn't bright enough to see by eye, an ultrasensitive video camera originally developed by Contag can detect the faint light and show researchers where the glowing cells have settled. The experiment highlighted a handful of stem cell resting places, including the spleen and the bone marrow in the verteb...New method could aid in prostate and breast cancer diagnosis
...entrations in breast cancer patients, requiring an ultrasensitive screening test for effective detection. Because proteins, unlike DNA, cannot be chemically duplicated yet, the Northwestern researchers had to develop a method of signaling the presence of a protein. They chose to use DNA as their signal because it c...American Physical Society March Meeting 2003
...rising in diverse areas. They are being studied as ultrasensitive sensors of gas molecules in the environment, as opticalsensors, and as mechanical sensors that can detect very slight bending. Nanotubes are also being explored as the basis for electronic devices. Results will be presented for nanotube version of tr...Bio-X grant recipient explores link between molecular chaperones and serious diseases
...ule spectroscopy, in which lasers, microscopes and ultrasensitive detectors follow one copy of the molecule of interest at a time. ``When this is done,`` she wrote, ``we can actually see how each copy of the protein may march to a different drummer. This is equivalent to watching just one dancer on a dance floor......n by Jun Hidema of Japan's Tohoku University to be ultrasensitive to UV damage. This could become an even more serious problem as earth's UV-filtering ozone layer continues to thin. Suspecting that Norin 1's UV sensitivity could be the result of a DNA repair deficiency, Betsy Sutherland, a Brookhaven Lab biologist,...... below the limit ofdetection of an investigational ultrasensitive assay1 (<50 copies). Anas-treated analysis evaluates only those patients who remain on studymedication through the entire study period. "In this trial, Agenerase appears to provide a significant amount of virussuppression when given in combinati...
