The Pathophysiology of Vasovagal Syncope and New Approaches to its Pharmacological Treatment
Published 2025-06-01“…Syncope refers to the transient loss of consciousness and the most common type of syncope is vasovagal syncope (VVS), usually occurring when a person is in an upright position, and/or after exposure to intense stress. The sequelae of VVS is caused by an increase in sympathetic tone and heart rate combined with an underfilled left ventricular chamber that leads to stimulation of cardiac afferent C fibers ultimately leading to bradycardia and vasodilation causing a reduction in venous return, cerebral hypoperfusion and VVS. …”

The alteration of neuronal activities of the cuneiform nucleus in non-hypovolemic and hypovolemic hypotensive conditions
Published 2021-01-01“…Abstract Background: The cuneiform nucleus is located in the center of the circuit that mediates autonomic responses to stress. Hemorrhagic hypotension leads to chemoreceptor anoxia, which consequently results in the reduction of baroreceptor discharge and stimulation of the chemoreceptor. …”

Research on 3D stability algorithm of spatial concave slope
Published 2025-07-01“…Furthermore, there is an exponential correlation between the three - dimensional stability coefficient and the radius of curvature; specifically, as the radius increases, the coefficient decreases gradually, with its rate of reduction becoming milder over time. This study successfully addresses the issue of three - dimensional stability on concave slopes and offers more dependable theoretical approaches for mining engineering.…”
