Afferent regulation of centrally generated activity is likely to be more complex than has been established. We show that a neuron that is an exteroceptor can also function as a proprioceptor. We study the Aplysia neuron B21. Previous data suggest that B21 functions as an exteroceptor during the radula closing/retraction phase of ingestive feeding. We show(More)
OBJECTIVES There are controversial opinions about the expediency of performance of the surgical angioplasty of the left main coronary artery (LMCA) and/or proximal segment of the right coronary artery (RCA) in rare cases of isolated lesion or with limited involving of distal coronary branches. One of the many fears restraining a wider performance of this(More)
The serotonergic metacerebral cells (MCCs) and homologous neurons in related mollusks have been extensively investigated within the context of feeding. Although previous work has indicated that the MCCs exert widespread actions, MCC modulation of sensory neurons has not been identified. We characterized interactions between the MCCs and a cell that is part(More)
Activated C protein (ACP) is a physiological anticoagulant enzyme that is capable to inactivate factors Va and VIIIa, thereby having a wide spectrum of antithrombotic effects. Low-dose ACP was tested for its ability to affect anodic current-induced arterial thrombosis in the rat. ACP given in low doses (15 micrograms/kg, 7% of total C protein in the rat)(More)
Left ventricle (LV) function and systemic hemodynamic changes after coronary artery embolization by 15 microns radioactive microspheres were studied in anesthetized rats. Selective coronary embolization was produced by microsphere injection during ascending aorta occlusion in closed chest animal by using "L"-shaped wire. Maximal pressure (Pmax) developed(More)
Mammary coronary bypass surgeries were performed in canine experiments. Myocardial perfusion was done via a shunt passing within the mammary artery and inserted into the distal portion of a coronary artery through a section, avoiding the application of extracorporeal circulation and myocardial ischemia. The method creates stenoses in any area of a vessel(More)
An important factor affecting movement of the blood through the coronary vessels is that contractions of the myocardium prevent the flow of blood along the vessels lying in its substance. This state of affairs is taken into account in the calculation of the total hydraulic resistance at the end of diastole, when the forces of systolic compression of the(More)
