Cuffless Single-Site Photoplethysmography for Blood Pressure Monitoring [PDF]

, 2020
One in three adults worldwide has hypertension, which is associated with significant morbidity and mortality. Consequently, there is a global demand for continuous and non-invasive blood pressure (BP) measurements that are convenient, easy to use, and ...

Cerebrovascular pulsatility following long duration spaceflight is associated with changes in pulse pressure and carotid artery stiffness

Experimental Physiology, EarlyView.
Abstract Central artery stiffening increases the haemodynamic pulsations transmitted downstream towards target organs, including the brain. While recent evidence suggests that long duration spaceflight is associated with reduced common carotid artery (CCA) distensibility, cerebrovascular pulsatility has not been extensively characterized in astronauts.

Cardiovascular disease biomarkers are associated with declining renal function in type 2 diabetes [PDF]

, 2017
Aims/hypothesis: We investigated whether biochemical cardiovascular risk factors and/or markers of subclinical cardiovascular disease were associated with the development of reduced renal function in people with type 2 diabetes.

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.

Assessing the blood pressure waveform of the carotid artery using an ultrasound image processing method [PDF]

Ultrasonography, 2017
Purpose The aim of this study was to introduce and implement a noninvasive method to derive the carotid artery pressure waveform directly by processing diagnostic sonograms of the carotid artery.

New insight of the implication blood pressure detection differences using aneroid sphygmomanometer and digital blood pressure on medical examination

Journal of Physics: Conference Series, 2020
Abstract The quality of medical devices is an important thing to establish the anamnesis, diagnosis and also treatment of patient. Arterial pressure measurement as one of the first indicators in the Hypertension Management Guidelines requires the accuracy as well as their function.

Eight weeks of post‐exercise local heating does not improve cognition and plasma brain‐derived neurotrophic factor concentrations

Experimental Physiology, EarlyView.
Abstract Exercise and heat stress have been reported to independently provide benefits to brain health. We tested the hypothesis that 8 weeks of post‐exercise local heating, passive local heating only, or exercise training only improves cognitive performance compared to a control group.

No difference in mean middle cerebral artery blood velocity responses between lower‐ and upper‐body unilateral resistance exercise in untrained individuals

Experimental Physiology, EarlyView.
Abstract Dynamic resistance exercise (RE) produces sinusoidal fluctuations in blood pressure that are mirrored by middle cerebral artery blood velocity (MCAv). However, whether lower‐ or upper‐body RE elicits a differential cerebrovascular response has not yet been examined.

Influence of oestradiol on exercise induced muscular damage and heart rate variability in a non‐trained healthy population

Experimental Physiology, EarlyView.
Abstract This study evaluates in non‐trained healthy women the influence of oestradiol (E2) on exercise induced muscular damage (EIMD) and performance. Thirty‐six young healthy women performed a step‐exercise until exhaustion, assessing the number of repetitions, pain perception and well‐being (questionnaires, 15 min and at 48 h post‐exercise), blood ...
