Frequency-dependent acceleration of relaxation involves decreased myofilament calcium sensitivity.
The force-frequency relationship is an intrinsic modulator of cardiac contractility and relaxation. Force of contraction increases with frequency, while simultaneously a frequency-dependent acceleration of relaxation occurs. While frequency dependency of calcium handling and sarcoplasmic reticulum calcium load have been well described, it remains unknown whether frequency-dependent changes in m...
متن کاملCardiac force-frequency relationship and frequency-dependent acceleration of relaxation are impaired in LPS-treated rats
INTRODUCTION Frequency-dependent acceleration of relaxation (FDAR) ensures appropriate ventricular filling at high heart rates and results from accelerated sarcoplasmic/endoplasmic reticulum calcium ATPase (SERCA) activity independent of calcium removal from the cell. Because lipopolysaccharide (LPS) challenge may induce aberrations in calcium trafficking and protein phosphorylation, we tested ...
متن کاملFrequency of Obsessive-compulsive Disorder in Methamphetamine-Dependent Subjects
Background and Objectives: Obsessive-compulsive disorder (OCD) is a type of anxiety disorder, which can be manifested as comorbidity with other psychological disorders. Prompt diagnosis and treatment of this comorbidity plays an important role in treatment of the main disorder. This study aimed to assess the frequency of OCD in methamphetamine-dependent individuals. <stro...
متن کاملVolume loading slows left ventricular isovolumic relaxation rate. Evidence of load-dependent relaxation in the intact dog heart.
We studied the effects of volume loading on left ventricular isovolumic relaxation rate in 16 intact anesthetized dogs. End-diastolic pressure, mean aortic systolic pressure, dp/dtmnx, and heart rate were measured at end expiration and end inspiration. Volume loading to approximately 5, 10, 15, and 20 mm Hg above initial end-diastolic pressure was performed. In nine dogs, simultaneous ventricul...
متن کاملStrain-rate frequency superposition: a rheological probe of structural relaxation in soft materials.
The rheological properties of soft materials often exhibit surprisingly universal linear and nonlinear features. Here we show that these properties can be unified by considering the effect of the strain-rate amplitude on the structural relaxation of the material. We present a new form of oscillatory rheology, strain-rate frequency superposition (SRFS), where the strain-rate amplitude is fixed a...
