Baroreflex and cerebral autoregulation are inversely correlated.
BACKGROUND The relative stability of cerebral blood flow is maintained by the baroreflex and cerebral autoregulation (CA). We assessed the relationship between baroreflex sensitivity (BRS) and CA in patients with atherosclerotic carotid stenosis or occlusion. METHODS AND RESULTS Patients referred for assessment of atherosclerotic unilateral >50% carotid stenosis or occlusion were included. Te...
متن کاملChiari Formation: Atlantoaxial Instability is the Cause
The entity of Chiari formation was described by Hans Chiari in 1891 [1,2]. Since then the subject has been evaluated elaborately by a number of authors. However, it may only be correct to state that confusion in the understanding of pathogenesis and the nature of anomaly, significance of associated abnormal soft tissue and bone anomalies and more importa...
متن کاملPreventing Instability Phenomenon in Gas-lift Optimization
One of the problems that sometimes occur in gas allocation optimization is instability phenomenon. This phenomenon reduces the oil production and damages downhole and surface facilities. Different works have studied the stability and suggested some solutions to override it, but most of them (such as making the well intelligent) are very expensive and thus they are not applicable to many cases. ...
متن کاملMathematical model of the interaction between baroreflex and cerebral autoregulation
Baroreflex (BR) and cerebral autoregulation (CA) are two important mechanisms regulating blood pressure and flow. However, the functional relationship between BR and CA in humans is unknown. Since BR impairment is an adverse prognostic indicator for both cardiac and cerebrovascular diseases it would be of clinical interest to better understand the relationship between BR and CA. Motivated by th...
