Altered sense of agency in schizophrenia: the aberrant effect of cardiac interoceptive signals

Frontiers in Psychiatry
BackgroundSchizophrenia (SZ) is characterized by abnormalities in self-representation, including a disturbed sense of agency (SoA). The continuous processing of sensory information concerning the internal state of the body (interoception) is argued to be

Impaired Windkessel function and proximal aortic stiffness: Linking vascular ageing to cognitive decline

Experimental Physiology, EarlyView.
Abstract Central arterial stiffening, particularly of the proximal aorta, is increasingly recognised as a pivotal contributor to cardiovascular disease, dementia, and mild cognitive impairment. Loss of Windkessel function amplifies pulsatile pressure, reduces diastolic perfusion and accelerates microvascular damage in the brain.

Breijo Electrocardiographic Pattern

Archivo Médico de Camagüey, 2018
Background: the decrease in cardiac electrical systole (short intervals of PR and QTc in the same electrocardiogram, also known as "Breijo electrocardiographic pattern") is increasingly studied.

No difference in mean middle cerebral artery blood velocity responses between lower‐ and upper‐body unilateral resistance exercise in untrained individuals

Experimental Physiology, EarlyView.
Abstract Dynamic resistance exercise (RE) produces sinusoidal fluctuations in blood pressure that are mirrored by middle cerebral artery blood velocity (MCAv). However, whether lower‐ or upper‐body RE elicits a differential cerebrovascular response has not yet been examined.

Noradrenergic regulation of skeletal muscle oxygen pressures: Impact of heart failure with preserved ejection fraction and heat therapy

Experimental Physiology, EarlyView.
Abstract Attenuation of sympathetic vasoconstriction during exercise (functional sympatholysis) contributes to skeletal muscle oxygen delivery–utilization matching. However, the extent to which muscle contractions impact noradrenergic regulation of interstitial oxygen pressures (PO2is${P_{{{\mathrm{O}}_2}}}_{{\mathrm{is}}}$; the driving force for blood–

Left ventricular morphological and functional predictors of V̇O2peak${\dot V_{{{\mathrm{O}}_2}{\mathrm{peak}}}}$: A 3‐year observational study

Experimental Physiology, EarlyView.
Abstract The aim of the study was to identify central determinants of V̇O2peak${\dot V_{{{\mathrm{O}}_2}{\mathrm{peak}}}}$ using a 3‐year longitudinal evaluation of left ventricular (LV) morphological and functional (global, tissue‐Doppler and strain) outcome measures obtained at rest and during both submaximal and maximal exercise in a group of highly
