Catheter-based examination for pulmonary microcirculatory function in patients with pulmonary hypertension.

PLoS ONE
A device that can evaluate human pulmonary microcirculation is currently unavailable. This study aimed to establish a novel approach for assessing pulmonary microcirculation in patients with pulmonary hypertension (PH).

Role of RIPK1/RIPK3/MLKL signalling pathway in sepsis‐associated acute kidney injury

Experimental Physiology, EarlyView.
Abstract Sepsis‐associated acute kidney injury (SA‐AKI) is a common clinical syndrome in critically ill patients, and its high mortality rate is closely related to complex pathological mechanisms. Existing studies have shown that the pathophysiological process of SA‐AKI involves complex multi‐mechanism interactions, including an uncontrolled systemic ...

Doppler Ultrasound Indices of the Major Arteries as Markers of Vascular Tone during Thermal Stress

Journal of Biomedical Photonics & Engineering
This study focuses on the effects of moderate thermal heating on microcirculation and peripheral hemodynamics, as well as on the interrelationship between changes detected by Laser Doppler Flowmetry (LDF) and Ultrasound Doppler (USD).

Passive thigh heating improves peak force production in younger adults and early isokinetic force production in younger and older adults

Experimental Physiology, EarlyView.
Abstract Older adults often suffer from reduced physical capability relative to young adults, in part due to impaired muscle function. This study investigated the ergogenic effects of passive thigh heating on knee extensor torque production in healthy older versus younger adults.

Small muscle mass aerobic exercise in health and disease: Unique insights into muscle vascular and metabolic control and performance

Experimental Physiology, EarlyView.
Abstract Studies of small muscle mass exercise (SMME) have revealed that the peripheral O2 transport–utilization cascade is a dynamically regulated system in which perfusive and diffusive components can be selectively amplified, redistributed and mechanically limited depending on contraction pattern, recruitment strategy and intramuscular pressure ...

Macro‐ and microcirculatory factors affecting foot temperature change during walking

Experimental Physiology, EarlyView.
Abstract Change in skin temperature is a complex process affected by several factors. During walking, increased microcirculatory activity, such as muscle metabolism, could increase foot temperature. The ensuing macrocirculatory responses, such as increased leg blood flow (LBF), might also increase foot temperature.

Impaired coronary flow reserve in patients with poor type 2 diabetes control: Preliminary results from prospective microvascular dysfunction registry

Cardiology Journal
BACKGROUND: Type 2 diabetes (DM) is a common comorbidity associated with cardiovascular disease, especially when poor glucose control is present. Extracardiac microcirculatory complications prevalence is well documented, however coronary microcirculatory

Neuromuscular fatigability with repeated exercise in hypoxia: From single‐joint paradigms to sprints

The Journal of Physiology, EarlyView.
Abstract figure legend Acute hypobaric or normobaric hypoxic exposure accelerates neuromuscular fatigability during repeated exercise. Indices of peripheral and central fatigue are not different at exhaustion in mild, moderate and severe hypoxia compared with normoxia, but task failure occurs earlier.

Scaling temporal resolution from mice to humans: Challenges and innovations in preclinical imaging of translational models

The Journal of Physiology, EarlyView.
Abstract figure legend Temporal scaling physiology differs significantly between mice and humans. Mice have higher metabolism, heart and respiratory rate, as well as faster blood flow rates, brain activity and physiological dynamics over time. These differences influence the temporal resolution needed in preclinical imaging of mouse models to ...
