Flame-retardant coatings are widely used in a variety of personnel or product protection, and many applications would benefit from film stretchability if suitable materials are available. It is challenging to develop flame-retardant coatings that are

The renin-angiotensin system (RAS) in twin-twin transfusion syndrome (TTTS) is up-regulated in the donor fetus's kidneys, but down-regulated in the recipient's. Ultrasonographic and echocardiographic features suggest that the recipient is also expose

In this study we aimed to quantitate monochorionic twin placental blood flow in vivo through arterio-venous anastomoses (AVA) and corresponding vessels within normal cotyledons.The topography of chorionic plate vasculature was mapped using colour Dop

Theoretical estimates and physiological inferences suggest that the structure of a shared cotyledon differs from a non-shared cotyledon. The aim of this study was to characterise the histomorphometry of terminal villi in shared and non-shared cotyled

Objective To determine if absent end-diastolic flow (AEDF) in the umbilical artery (UA) has a longer latency in monochorionic (MC) twin fetuses compared to singleton or dichorionic twin (DC) fetuses. Methods One hundred and eight pregnancies with a f

Objective To characterise arterio-venous anastomoses (AVA) in monochorionic (MC) placentae and determine (i) whether shared cotyledons lie beneath the co-termination of an artery from one twin and a vein to the contralateral twin and (ii) whether all

OBJECTIVE Treatment selection in twin-twin transfusion syndrome is increasingly determined by disease severity. We investigated whether detection of arterio-arterial anastomoses predicts perinatal survival. METHODS An artery-artery anastomosis was so

To determine the frequency of reversal of transfusional gradient and phenotype in a large cohort of prospectively studied cases of twin-twin transfusion syndrome (TTTS) and seek evidence of clinical or placental anastomotic associations.Consecutive c

Objectives: To characterize the phenomenon of retrograde transmission of arterio-arterial anastomosis (AAA) interference patterns on umbilical artery (UA) waveform by (a) documenting the periodicity, (b) correlation with in vivo and in vitro demonstr

In this paper we outline the hyperbolic system of governing equations describing one-dimensional blood flow in arterial networks. This system is numerically discretised using a discontinuous Galerkin formulation with a spectral/hp element spatial app
