Optoacoustic, noninvasive, real-time, continuous monitoring of cerebral blood oxygenation: an in vivo study in sheep.
BACKGROUND Current, invasive cerebral oxygenation monitors require either retrograde jugular venous bulb cannulation or intraparenchymal probe insertion. There is no accurate, noninvasive, continuous monitor of cerebral blood oxygenation. METHODS The authors designed, built, and tested novel optoacoustic instrumentation that continuously measures blood oxygenation in the superior sagittal sin...
متن کاملOptoacoustic spectroscopy for real-time monitoring of strongly light-absorbing solutions in applications to analytical chemistry☆
An optoacoustic technique for solutions of strongly light-absorbing analytes at 0.1-0.01 mol l(-1) is proposed. The technique is based on the wide-band forward mode detection of temporal profiles of laser-generated ultrasonic pulses (optoacoustic signals). The leading edge of the signal repeats the distribution of the laser fluence in the medium, which makes it possible to determine its optical...
متن کاملReal-time optoacoustic monitoring of vascular damage during photodynamic therapy treatment of tumor.
The optoacoustic technique is a noninvasive imaging method with high spatial resolution. It potentially can be used to monitor anatomical and physiological changes. Photodynamic therapy (PDT)-induced vascular damage is one of the important mechanisms of tumor destruction, and real-time monitoring of vascular changes can have therapeutic significance. A unique optoacoustic system is developed fo...
متن کاملEvaluation of GNMT Gene Expression in Prostate Cancer Tissues using Real-Time PCR
Introduction: Prostate cancer is the second most common cancer and the leading cause of cancer-related deaths worldwide. In the present study, the expression level of glycine N-methyl transferase gene (GNMT) was investigated in prostate cancer tissue. The GNMT enzyme is encoded by the GNMT gene. Increased GNMT gene expression increases the conversion of glycine to sarcosine and results in the e...
متن کاملOptoacoustic Monitoring of Physiologic Variables
Optoacoustic (photoacoustic) technique is a novel diagnostic platform that can be used for noninvasive measurements of physiologic variables, functional imaging, and hemodynamic monitoring. This technique is based on generation and time-resolved detection of optoacoustic (thermoelastic) waves generated in tissue by short optical pulses. This provides probing of tissues and individual blood vess...
