Physiological mechanisms underlying enhanced performance with blood flow restriction training: neuromuscular, vascular and metabolic adaptations

The Journal of Physiology, EarlyView.
Abstract figure legend We investigated how 6 weeks of dynamic knee‐extensor interval training with blood flow restriction (BFR‐leg) and without (CTRL‐leg) impacts performance and its mechanisms using non‐invasive methods. Specifically, we used gold‐standard methods to assess neuromuscular function, vascular function using Doppler ultrasound, and near ...

Role of reactive oxygen species in mediating peripheral hypoxic vasodilation and sympathoexcitation at high altitude

The Journal of Physiology, EarlyView.
Abstract figure legend High‐altitude acclimatisation increases muscle sympathetic nerve activity (MSNA) via activation of the arterial chemoreflex, pulmonary arterial baroreceptors and resetting of the sympathetic vascular baroreflex. However attempting to silence these mechanisms only partially normalises MSNA, implicating other contributory ...

The influence of metaboreflex activation on pulmonary pressure with combined chemoreflex activation in acute and chronic hypoxia

The Journal of Physiology, EarlyView.
Abstract figure legend Activation of both the metaboreflex via post‐exercise circulatory occlusion and the chemoreflex via acute and chronic hypoxia increased pulmonary artery systolic pressure. Coactivation of these reflexes further increased pulmonary artery pressure in an additive manner.

Ultrasound‐based haemodynamic force trajectories in a murine model of reversible pressure overload

The Journal of Physiology, EarlyView.
Abstract figure legend High‐resolution ultrasound anatomical imaging and speckle‐tracking analysis were used to compute left ventricular (LV) haemodynamic forces (HDF) in a murine model of transverse aortic constriction (TAC) followed by aortic debanding (deTAC).

Phase I/II Prospective Study on Endoscopic Ultrasound‐Guided Hepaticogastrostomy as Primary Drainage for Unresectable Malignant Hilar Biliary Obstruction

DEN Open, Volume 7, Issue 1, April 2027.
ABSTRACT Objectives Various drainage methods have been used for unresectable malignant hilar biliary obstruction (MHBO). However, controlling cholangitis and obstructive jaundice is still challenging. We performed a phase I/II study of endoscopic ultrasound‐guided hepaticogastrostomy (EUS‐HGS) as primary drainage for MHBO.

Physical Principles of Doppler and Color Doppler Ultrasound

2021
Doppler ultrasound is based on application of the Doppler effect, also called the Doppler shift. In medicine the ultrasound wave is reflected off the moving objects which are erythrocytes in blood vessels. The following types of applications of the Doppler shift in diagnostic imaging are distinguished: Spectral Doppler, including Continuous wave ...
