... light as it emerges from the eye. This produces a precise three-dimensional map of the eye's visual system, including the cornea's imperfections or aberrations. The wavefront data is translated into a mathematical formula that the surgeon uses to program corrections into the laser, which vaporizes tissue to...Gene expression profiling may lead to customized treatments for pediatric leukemia patients
...gene expression profiling may provide an even more precise profile of a patient's disease. Researchers from St. Jude Children's Research Hospital in Memphis, Tenn., utilized DNA microarray technology to study the pattern of genes expressed in a leukemic cell. DNA microarrays, also called gene chips, contain...Molecular test proves to be effective in measuring remission and relapse after cancer treatment

"Learning how the human genome instructs precise expression of roughly 30,000 genes during embryo development and normal physiological processes has become the next frontier in biomedical research." He added that his research team will devise an integrated approach combining experimental and comput...Scientists map maturation of the human brain
... an extension of a prior NIMH sample, permits more precise understanding of brain development in relation to its functional maturation, and provides the first video maps of brain development. For this study, 13 healthy children were selected from the NIMH sample, who had 3-5 sequential MRI scans; each repeat...Rochester chosen to focus on rare neurological diseases

...post-doctoral fellow Jun Komano, PhD, examined the precise way in which EBV affects B cells that evolve to be tumors. Under normal conditions, B cells mount responses to invading organisms by making protective antibodies and then dying. But with Burkitt's lymphoma, the system breaks down.
