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

Development of the Human Placenta and Fetal Heart: Synergic or Independent?
Frontiers in Physiology, 2018 The placenta is the largest fetal organ, and toward the end of pregnancy the umbilical circulation receives at least 40% of the biventricular cardiac output.

Resistance Mechanisms to Anti-angiogenic Therapies in Cancer
Frontiers in Oncology, 2020 Tumor growth and metastasis rely on tumor vascular network for the adequate supply of oxygen and nutrients. Tumor angiogenesis relies on a highly complex program of growth factor signaling, endothelial cell (EC) proliferation, extracellular matrix (ECM ...

METOCLOPRAMIDE AND RENAL VASCULAR RESISTANCE
British 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
Endocrine 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 ...

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