Stimulation with bipolar electrodes of specific loci in stellate ganglia elicited in anesthetized piglets, 1-4 weeks of age, alterations in cardiac function and aortic pressure. Responses were also elicited by chemical stimulation in specific loci of these ganglia. The probability of eliciting a cardiovascular response by stimulating loci in a stellate(More)
BACKGROUND Dual energy CT (DECT) has proven its potential in oncological imaging. Considering the repeated follow-up examinations, radiation dose should not exceed conventional single energy CT (SECT). Comparison studies on the same scanner with a large number of patients, considering patient geometries and image quality, and exploiting full potential of(More)
In developing kittens, antagonism of N-methyl-D-aspartate receptors by systemic injections of MK-801 produced: (a) blockage of the inspiratory off-switch, prolonging phrenic and hypoglossal discharges; (b) age-dependent changes of sympathetic inspiratory discharges, elimination of inspiratory-related discharges in animals less than or equal to 36 days old(More)
PURPOSE Dynamic CT perfusion (CTP) consists in repeated acquisitions of the same volume in different time steps, slightly before, during and slightly afterwards the injection of contrast media. Important functional information can be derived for each voxel, which reflect the local hemodynamic properties and hence the metabolism of the tissue. Different(More)
