We report on oxygenation changes noninvasively recorded by multichannel continuous-wave near infrared spectroscopy (CW-NIRS) during endovascular neuroradiologic interventions requiring temporary balloon occlusion of arteries supplying the cerebral circulation. Digital subtraction angiography (DSA) provides reference data on the site, timing, and effectiveness of the flow stagnation as well as on the amount and direction of collateral circulation. This setting allows us to relate CW-NIRS findings to brain specific perfusion changes. We focused our analysis on the transition from normal perfusion to vessel occlusion, i.e., before hypoxia becomes clinically apparent. The localization of the maximal response correlated either with the core (occlusion of the middle cerebral artery) or with the watershed areas (occlusion of the internal carotid artery) of the respective vascular territories. In one patient with clinically and angiographically confirmed insufficient collateral flow during carotid artery occlusion, the total hemoglobin concentration became significantly asymmetric, with decreased values in the ipsilateral watershed area and contralaterally increased values. Multichannel CW-NIRS monitoring might serve as an objective and early predictive marker of critical perfusion changes during interventions—to prevent hypoxic damage of the brain. It also might provide valuable human reference data on oxygenation changes as they typically occur during acute stroke. 相似文献

Background
Tools for predicting post-ICU patients’ outcomes are scarce. A single-center study showed that the Sabadell score classified patients into four groups with clear-cut differences in ward mortality. 相似文献74.

Mitochondrial function in myocardial stunning 总被引:1,自引:0,他引:1

Mitochondrial respiration parameters were studied in mitochondria isolated from normal, ischemic and post-ischemic rabbit hearts. Mitochondrial function was related to tissue content of high energy phosphates (HEP) and cardiac function in the isolated working rabbit heart preparation. It was found that after 10 and 20 mins of global normothermic ischemia followed by 20 mins of Langendorff reperfusion, mitochondrial function and HEP content of the myocardium were not significantly diminished. Myocardial creatine phosphate even showed a significant overshoot as compared to the pre-ischemic condition. When these hearts were allowed to perform work, recovery of cardiac function was incomplete while mitochondrial function and HEP content remained in the normal range. Prolonged ischemia (30 mins) resulted in a significant depression of mitochondrial function and myocardial ATP content during and after ischemia. Recovery of contractile function was severely depressed. These results show that impaired cardiac function after a mild ischemic insult (myocardial stunning) can be associated with near normal mitochondrial function and HEP contents. 相似文献

Diazonium-functionalized thin films from the spontaneous reaction of p-phenylenebis(diazonium) salts
Salts of the diazonium coupling agent p-phenylenebis(diazonium) form diazonium-terminated conjugated thin films on a variety of conductive and nonconductive surfaces by spontaneous reaction of the coupling agent with the surface. The resulting diazonium-bearing surface can be reacted with various organic and inorganic nucleophiles to form a functionalized surface. These surfaces have been characterized with voltammetry, XPS, infrared and Raman spectroscopy, and atomic force microscopy. Substrates that can be conveniently and quickly modified with this process include ordinary glass, gold, and an intact, fully assembled commercial screen-printed carbon electrode. The scope and convenience of this process make it promising for practical surface modification.We present a surface functionalization procedure based on diazonium-functionalized thin films produced by spontaneous surface grafting of p-phenylene-bis(diazonium) cation. 相似文献
