Modelling the effect of vascular status on tumour evolution and outcome after thermal therapy [PDF]

open access: yesarXiv, 2022
Microscale oxygenation plays a prominent role in tumour progression. Spatiotemporal variability of oxygen distribution in the tumour microenvironment contributes to cellular heterogeneity and to the emergence of normoxic and hypoxic populations.

Vascular stiffness in insulin resistance and obesity [PDF]

open access: yesFrontiers in Physiology, 2015
Obesity, insulin resistance, and type 2 diabetes are associated with a substantially increased prevalence of vascular fibrosis and stiffness, with attendant increased risk of cardiovascular and chronic kidney disease. Although the underlying mechanisms and mediators of vascular stiffness are not well understood, accumulating evidence supports the role ...

Anxiety increases the blood pressure response during exercise

open access: yesMotriz: Revista de Educacao Fisica, 2019
Aim: The hypothesis that higher levels of anxiety promote greater blood pressure (BP) responses during physical exercise is tested. The hypothesis that metaborreflex response is increased in an anxious individual is tested as well. Methods: There were

METOCLOPRAMIDE AND RENAL VASCULAR RESISTANCE

open access: yesBritish Journal of Anaesthesia, 1991
We have studied the effect of i.v. metoclopramide on renal vascular resistance in nine healthy volunteers. Peak systolic and end-diastolic frequencies were measured using duplex Doppler ultrasound of a renal interlobar artery, before and after the administration of i.v. metoclopramide 10 mg, and the resistance index derived.

Central and peripheral pathogenetic forms of type 2 diabetes: a proof-of-concept study

open access: yesEndocrine Connections, 2016
Hypothesis Previous studies provide evidence that glycated haemoglobin (HbA1c) and fasting plasma glucose (FPG) should not be considered as interchangeable alternatives in the diagnosis of the same type 2 diabetes, but as indicators of its different ...

Increased Serum Klotho With Age-Related Aortic Stiffness and Peripheral Vascular Resistance in Young and Middle-Aged Swine

open access: yesFrontiers in Physiology, 2020
The anti-aging function of Klotho gene has been implicated in age-related diseases. The physiological importance of Klotho in the progression of arterial stiffness with aging, however, remains unclear.

Image-Based Modeling of Blood Flow and Oxygen Transfer in Feto-Placental Capillaries [PDF]

open access: yesPLoS ONE 11(10):e0165369 (2016), 2016
During pregnancy, oxygen diffuses from maternal to fetal blood through villous trees in the placenta. In this paper, we simulate blood flow and oxygen transfer in feto-placental capillaries by converting three-dimensional representations of villous and capillary surfaces, reconstructed from confocal laser scanning microscopy, to finite-element meshes ...

Ornipressin in the treatment of functional renal failure in decompensated liver cirrhosis [PDF]

open access: yes, 1991
In 11 patients with decompensated cirrhosis and deteriorating renal function, the effect of the vasoconstrictor substance 8-ornithin vasopressin (ornipressin; POR 8; Sandoz, Basel, Switzerland) on renal function, hemodynamic parameters, and humoral ...

Angiotensin receptor blockade with Losartan attenuates pressor response to handgrip contraction and enhances natriuresis in salt loaded hypertensive subjects: a quasi-experimental study among Nigerian adults

open access: yesThe Pan African Medical Journal, 2019
INTRODUCTION: Sympathetic and Renin-Angiotensin-Aldosterone systems play crucial roles in blood pressure response to increased salt intake. This study investigated the effects of angiotensin receptor blocker (ARB) and sympathetic excitation on the ...
