All Is Relative—A Call for Considering “Physiologically Informed” Control Conditions to Improve the Mechanistic Understanding of the Effects of Physical Exercise on Cognition

Scandinavian Journal of Psychology, Volume 67, Issue 5, Page 1246-1266, October 2026.
ABSTRACT There is a growing interest in elucidating the mechanisms that drive the benefits of physical exercise on cognitive performance. A key element for a better understanding of a particular phenomenon (e.g., the mediators of the exercise‐cognition interaction) is the selection of an appropriate control condition/group as the basis for causal ...

Perioperative propranolol during robotic‐assisted radical prostatectomy: A randomised, double‐blind, placebo‐controlled, pilot trial (PeP‐RALP)

BJUI Compass, Volume 7, Issue 9, September 2026.
Abstract Objective This study aimed to determine the feasibility and safety of administering perioperative propranolol, as an adjunct to reduce prostate cancer recurrence, in patients undergoing robotic‐assisted laparoscopic prostatectomy (RALP) for European Association of Urology (EAU) intermediate‐ or high‐risk prostate cancer.

Transcranial Color‐Coded Duplex Sonography in Large‐Vessel Vasculitis Compatible With Takayasu Arteritis Presenting Intracranial Involvement and Vertebrobasilar Dolichoectasia: A Case Report

Journal of Clinical Ultrasound, Volume 54, Issue 7, Page 1710-1716, September 2026.
This case illustrates sequential intracranial occlusions in large‐vessel vasculitis compatible with Takayasu arteritis preserving perfusion through robust collateral pathways. Transcranial color‐coded duplex sonography identified characteristic blunted flow patterns and focal turbulence, underscoring its value in detecting hemodynamic compromise beyond

Detection of microemboli by transcranial Doppler ultrasound.

Texas Heart Institute journal, 1997
Doppler ultrasound detection of abnormally high-pitched signals within the arterial waveform offers a new method for diagnosis, and potentially for prediction, of embolic complications in at-risk patients. The nature of Doppler "microembolic" signals is of particular interest in patients with prosthetic heart valves, where a high prevalence of these ...

The Range of Examinations and Roles Performed by Sonographers in Australia and New Zealand: What Does It Mean for a Profession‐Based Career Framework?

Sonography, Volume 13, Issue 3, September 2026.
ABSTRACT Introduction Many sonographers in Australia and New Zealand (ANZ) do not work within an institutional career framework, have no or limited progression opportunities, or are unsure how to progress their careers. This may limit professional growth and advancement.

Confined spaces in space: Cerebral implications of chronic elevations of inspired carbon dioxide and implications for long‐duration space travel

Experimental Physiology, Volume 111, Issue 9, Page 3968-3982, 1 September 2026.
Abstract Cerebrovascular regulation is critically dependent upon the arterial partial pressure of carbon dioxide (PaCO2${P_{{\mathrm{aC}}{{\mathrm{O}}_{\mathrm{2}}}}}$), owing to its effect on cerebral blood flow, tissue PCO2${P_{{\mathrm{C}}{{\mathrm{O}}_{\mathrm{2}}}}}$, tissue proton concentration, cerebral metabolism and cognitive and neuronal ...
