Regional changes in cerebral blood flow between the upright and supine posture and over 3 days of bed rest

open access: yesExperimental Physiology, EarlyView.
Abstract A reduction in cerebral blood flow (CBF) has been observed during spaceflight and bed rest. We aimed to examine the magnitude and regional heterogeneity of the decrease in CBF during bed rest compared to posture changes on Earth. Seventeen participants (age, 29 ± 9 years, 7 females) were studied in the upright and supine posture and over 3 ...

The effects of uninterrupted and interrupted sitting on blood pressure and arterial stiffness in patients with established coronary heart disease

open access: yesExperimental Physiology, EarlyView.
Abstract Sedentary behaviour is an independent risk factor for cardiovascular disease. In healthy adults, prolonged uninterrupted sitting acutely increases blood pressure (BP) and aortic stiffness; however, these effects can be mitigated with light physical activity interruptions.

A constitutive modelling framework for applications to in vivo longitudinal data: Evaluation in a 60‐day head‐down bed rest study on arterial function

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend We proposed a computational constitutive modelling framework that leverages longitudinal acquisitions of haemodynamic waveforms at multiple arterial locations to achieve a biomechanical characterisation of their (micro)structural remodelling processes.

Maximal exercise at high altitude does not exacerbate inflammation in the human brain

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend This study investigated arterial–internal jugular venous (IJV) exchange of cytokines in response to low‐intensity and maximal cycling exercise at sea level and following 6–8 days at 3800 m a.s.l. There was a shift towards net release of interleukin‐6 (IL‐6), interleukin‐8 (IL‐8), monocyte chemoattractant protein‐1 (MCP‐1) and ...

Transvaginal Ultrasonography for Detection of PID‐Related Adhesions: A Case Report

open access: yesAustralasian Journal of Ultrasound in Medicine, Volume 29, Issue 3, August 2026.
ABSTRACT Background Diagnosis of acute and chronic pelvic inflammatory disease continues to be a challenge despite advances in investigative procedures. Complications of PID include infertility, chronic pelvic pain and ectopic pregnancy. Currently, transvaginal ultrasonography is primarily used to detect tubo‐ovarian abscesses (TOA) or pyosalpinx.

π‐Radical Cascades to Peri‐Fused Triangulene Dimers

open access: yesAngewandte Chemie, Volume 138, Issue 27, 1 July 2026.
We demonstrate the potential of open‐shell molecular graphene fragments as synthons for constructing graphene nanostructures via π‐radical cascades. By identifying monoradical intermediates as key selectivity‐determining species and tuning steric effects in a triangulene precursor, we show that reactivity in a formally diradical system can be ...

Placental crises: disruptive selection and maternal under‐investment as the foundations of mammalian placental evolution and dysfunction

open access: yesBiological Reviews, Volume 101, Issue 4, Page 1627-1640, August 2026.
ABSTRACT Among the vertebrates, mammals are notable for the dominance of live birth and placental nutrition. The structural diversity of the mammalian placenta is remarkable, despite sharing a single common ancestor and conserved physiological functions.
