The purpose of this experimental study was to examine the differences between peripheral nerve stimulation and direct spinal stimulation in generating cortical somatosensory-evoked potential (SEP) responses for monitoring spinal cord ischemia during thoracic aorta cross-clamping. Adult mongrel dogs (n = 6) were placed under general anesthesia and a left(More)
Experiments were carried out in order to further delineate the pathophysiology of the fall of plasma 5-hydroxytryptamine (5-HT) during a migraine attack. Platelets from normal subjects were incubated with 14C-labelled 5-HT, and the release of 5-HT was measured following exposure of these platelets to plasma taken from migraine patients during an attack or(More)
Most of the blood tests aiming for breast cancer screening rely on quantification of a single or few biomarkers. The aim of this study was to evaluate the feasibility of detecting breast cancer by analyzing the total biochemical composition of plasma as well as peripheral blood mononuclear cells (PBMCs) using infrared spectroscopy. Blood was collected from(More)
placed 102 seed traps at 12 levels along a 45-m high tower, with the three upper levels above the tallest trees (33 m). Traps were checked at weekly or biweekly intervals. We surveyed all trees in a radius of 50 m around the tower. Trees were identified to species, mapped on a 2.5-m grid, and measured for DBH (diameter at breast height, 1.3 m). For a sample(More)
In an effort to explore possible changes in 5-hydroxytryptamine (5-HT) metabolism in idiopathic torsion dystonia (ITD), platelets from patients were studied. Platelet 5-HT concentrations did not differ from those in matched controls. 5-HT uptake by the platelets was also studied, and the results demonstrated significantly higher Km values, but Vmax values(More)
