Mathematical Modeling of Arterial Blood Pressure Using Photo-Plethysmography Signal in Breath-hold Maneuver

, 2018
Recent research has shown that each apnea episode results in a significant rise in the beat-to-beat blood pressure and by a drop to the pre-episode levels when patient resumes normal breathing. While the physiological implications of these repetitive and

Role of S1P‐ and Rho‐kinase signalling in age‐related myogenic tone deficiency in murine resistance arteries

Experimental Physiology, EarlyView.
Abstract Ageing is a risk factor for cardiovascular and neurodegenerative diseases. The myogenic response in resistance arteries is responsible for basal (myogenic) tone and blood flow autoregulation. G‐protein‐coupled receptors and G12/RhoA/Rho kinase are implicated in myogenic tone (MT), and we aimed to clarify their role in pressure sensing and ...

Evidence for early endothelial dysfunction associated with the ALDH2 rs671 gene variant: A preliminary investigation with young East Asians

Experimental Physiology, EarlyView.
Abstract Aldehyde dehydrogenase 2 (ALDH2) is a mitochondrial enzyme that plays an important role in aldehyde detoxification. A large percentage (30–50%) of the East Asian population carry a single point mutation in the ALDH2 gene (ALDH2*2 variant) that causes a severe reduction or lack of ALDH2 enzyme activity, and leads to disrupted cellular ...

Postexercise muscle oxygen uptake kinetics in older breast cancer survivors and healthy individuals: Association with myosteatosis

Experimental Physiology, EarlyView.
Abstract Reduced cardiorespiratory fitness is common among breast cancer survivors and, although traditionally attributed to cardiac dysfunction, might also be related to peripheral skeletal muscle abnormalities. We examined peak and submaximal plantar‐flexion exercise and recovery kinetics for lower‐leg oxygen uptake (V̇O2${\dot V_{{{\mathrm{O}}_2}}}$)

Prevalence of clinically significant Hepatopulmonary Syndrome among Patients with Chronic Liver Disease and Portal Hypertension

مجله كليه طب الكندي, 2011
Background : The hepatopulmonary syndrome (HPS) is defined as the triad of liver disease, arterial deoxygenation, and pulmonary vascular dilatation. The reported prevalence of HPS in cirrhotic patients varies between 5% -17.5%.Objective : To estimate ...

Neuromuscular and neuromechanical assessments of respiratory performance in the mdx mouse model of Duchenne muscular dystrophy across the natural history of disease

Experimental Physiology, EarlyView.
Abstract Duchenne muscular dystrophy (DMD) is a severe life‐limiting X‐linked neuromuscular disorder characterised by progressive skeletal muscle degeneration and respiratory failure. The mdx mouse, lacking dystrophin, is the most widely used preclinical model of DMD, yet the trajectory of respiratory dysfunction in this model remains incompletely ...

Acute ketone monoester ingestion lowers resting cerebral blood flow: a randomized cross‐over trial

The Journal of Physiology, EarlyView.
Abstract figure legend This double‐blind, placebo‐controlled, randomized cross‐over trial investigated the effects of ketone monoester (KME) ingestion on resting cerebral blood flow (CBF) in young adults. We demonstrate that KME supplementation lowers CBF in a dose‐dependent manner over 2‐houra post‐ingestion, whereas CBF remained unchanged following ...
