Stimulus‐dependent sex differences in dyspnoea: Mechanical loading vs. hypercapnia

Experimental Physiology, EarlyView.
Abstract Dyspnoea is a multidimensional sensation of breathing discomfort that varies in sensory and affective experience. During exercise, healthy adults commonly report dyspnoea sensations of ‘air hunger’ and ‘work/effort’, with females more frequently reporting air hunger at maximal exertion.

Senolytics and exercise: Dual modalities for rejuvenating muscle

The Journal of Physiology, EarlyView.
Abstract figure legend The role of senolytics on the heart and skeletal muscle. Senescent cell burden increases with ageing, disuse and disease. The senolytics dasatinib+quercetin (D+Q), navitoclax and fisetin, as well as exercise, eliminate senescent cells, reducing senescent cell burden and their senescence‐associated secretory phenotype (SASP ...

Dynamic modeling and analysis of the rotor system with cracked double diaphragm coupling

Jixie qiangdu
ObjectiveAiming at the insufficient research on the dynamic characteristics of the rotor system with cracked double diaphragm coupling, the cross-coupling term of coupling stiffness was considered, and the time-varying stiffness matrix of the cracked ...

Cannabinoid exposure during pregnancy: Cardiorespiratory effects and offspring outcomes

The Journal of Physiology, EarlyView.
Abstract figure legend Prenatal exposure to cannabinoids has been investigated across human and animal studies to understand its impact on physiological development. Evidence suggests that early‐life cannabinoid exposure influence multiple developmental processes, extending beyond neurodevelopmental outcomes to potentially affect placental function ...

Biomimetic direction-sensitive micromachined diaphragm for ultrasonic transducers

, 2001
This paper presents a novel biomimetic direction-sensitive micromachined diaphragm for ultrasonic transducers. The diaphragm design is based on the mechanical model of the parasitoid fly, Ormia ochracea's ears which achieve directionality through ...

Skeletal muscle adaptation to muscle activity and hypoxia: Differential structural and metabolic remodelling

The Journal of Physiology, EarlyView.
Abstract figure legend There has been controversy about the structural (capillary) response of skeletal muscle to altered O2 status, involving decreased supply (hypoxia) or increased demand (activity). Here we demonstrate that seven days of activation of skeletal muscle by indirect electrical stimulation led to significant expansion of the capillary ...

β‐hydroxy‐β‐methylbutyrate improves fast‐twitch muscle function, histopathology and mitochondrial respiration in the D2.mdx dystrophic mouse

The Journal of Physiology, EarlyView.
Abstract figure legend β‐Hydroxy‐β‐methylbutyrate (HMB) enhances fast‐twitch muscle and mitochondrial function in D2.mdx mice. Male DBA/2J (wild‐type) and D2.mdx mice aged 3 or 6 months received daily β‐hydroxy‐β‐methylbutyrate (HMB; 1 mg g−1 day−1) via drinking water for 8 weeks. Fast‐twitch extensor digitorum longus (EDL) and slow‐twitch soleus (SOL)

CO2 chemoreflex contributions to ventilatory long‐term facilitation

The Journal of Physiology, EarlyView.
Abstract figure legend To determine whether changes in CO2 chemoreflex sensitivity contribute to ventilatory long‐term facilitation (LTF), we tested the hypothesis that hypercapnic acute intermittent hypoxia (AIH) induces ventilatory LTF and enhances peripheral, but not central, chemoreceptor CO2 chemoreflex sensitivity.

“Two‐For‐One”: 4D Cardiac and Pulmonary MR Imaging From a Single Acquisition Using bSTAR

Magnetic Resonance in Medicine, Volume 96, Issue 5, Page 2213-2227, November 2026.
ABSTRACT Purpose To generate 4D (3D+time) images of both the heart and lungs using a single volumetric radial free‐breathing bSSFP dual echo acquisition (bSTAR) with two image reconstructions within a single pipeline deployed inline at 0.55 and 1.5 T.
