Biomarker boom slowed by validation concerns.
By many accounts, the brave new worlds of genomics and proteomics— and their accompanying technologies— have ushered in a new era of cancer biomarker research. Researchers in cancer detection, diagnosis, and treatment all have a vested interest in discovering these proteins and small molecules that are telltale signs of early cancer, characteristics that make a type of cancer unique, or markers...
متن کاملBiomarker discovery and validation.
Currently available biomarkers, such as those used to diagnose myocardial infarction (e.g., cardiac troponins), were identified in the course of targeted physiologic studies. Similarly, basic investigation of diseases has largely been characterized by studies of isolated molecules in cellular systems. Advances in genomics technologies, however, are beginning to permit characterization of global...
متن کاملOutput-Adaptive Tetrahedral Cut-Cell Validation for Sonic Boom Prediction
A cut-cell approach to Computational Fluid Dynamics (CFD) that utilizes the median dual of a tetrahedral background grid is described. The discrete adjoint is also calculated, which permits adaptation based on improving the calculation of a specified output (off-body pressure signature) in supersonic inviscid flow. These predicted signatures are compared to wind tunnel measurements on and off t...
متن کاملValidation of a blood plasma separation system by biomarker detection.
A microfluidic system was developed for blood plasma separation at high flow rate. This system uses only hydrodynamic forces to separate plasma from whole blood. The microfluidic network features a series of constrictions and bifurcations to enhance the product yield and purity. A maximum purity efficiency of 100% is obtained on blood with entrance hematocrit level up to 30% with a flow rate of...
متن کاملSlowed Prosaccades and Increased Antisaccade Errors As a Potential Behavioral Biomarker of Multiple System Atrophy
Current clinical diagnostic tools are limited in their ability to accurately differentiate idiopathic Parkinson's disease (PD) from multiple system atrophy (MSA) and other parkinsonian disorders early in the disease course, but eye movements may stand as objective and sensitive markers of disease differentiation and progression. To assess the use of eye movement performance for uniquely charact...
