We hypothesize that combining quantitative near-infrared spectroscopy (NIRS) with established invasive techniques will enable advanced insights into renal hemodynamics and oxygenation in small animal models. We developed a NIRS technique to monitor absolute values of oxygenated and deoxygenated hemoglobin and of oxygen saturation of hemoglobin within the renal cortex of rats. This NIRS techniqu...
We used Near-Infrared Spectroscopy (NIRS) to simultaneously measure brain activity in two people while they played a computer-based cooperation game side by side. Inter-brain activity coherence was calculated between the two participants. We found that the coherence between signals generated by participants' right superior frontal cortices increased during cooperation, but not during competitio...
Introduction The FORE-SIGHT monitor measures absolute cerebral tissue oxygen saturation (SctO2) of the frontal lobes of the brain, in a non-invasive way, through near-infrared spectroscopy (NIRS) [1]. Its value for early detection of hemodynamic deterioration in the postoperative phase after congenital cardiac surgery has never been examined. In a prospective observational study [2], 300 mechan...
Adequate biogeochemical characterization and monitoring of aquatic ecosystems, both for scientific purposes and for water management, pose high demands on spatial and temporal replication of chemical analyses. Near-infrared reflectance spectroscopy (NIRS) may offer a rapid, low-cost and reproducible alternative to standard analytical sample processing (digestion or extraction) and measuring tec...
