Surface Rendering of Cross-Sectional Imaging and Medical Illustration for Perinatal Planning in Conjoined Twins.

Introduction: Surface rendering of diagnostic imaging data can reveal hidden conditions with an almost life-like realism. However, early gestation images alone are often insufficient to accurately predict postnatal anatomy. Yet, time-sensitive decisions may have to be made before detailed imaging becomes possible.

Degradation of antipyrine in water with activated persulfate aided with biochar of olive pomace.

The degradation of antipyrine (AP) in water has been studied using persulfate activated with biochar obtained from gasification of olive pomace (BC) combined with ferric salts in the presence of UV-A radiation. Firstly, the adsorption of AP on biochar was evaluated. The data were adjusted using various kinetic models verifying that AP adsorption on BC occurs in three stages and follows pseudo-second order kinetics.

Pupil reflex as a marker of activity and prognosis in heart failure: a longitudinal and prospective study.

Aims: Compensatory mechanisms in heart failure (HF) are triggered to maintain adequate cardiac output. Among them, hyperactivation of the sympathetic nervous system (SNS) is one of the main ones and carries a worse prognosis. The pupillary reflex depends on the SNS, and we can evaluate it through pupillometry.

Fluid Flow Analysis of Neonatal Dual-Lumen Cannulas for Venovenous Extracorporeal Membrane Oxygenation.

Hemolysis persists as a common and serious problem for neonatal patients on extracorporeal membrane oxygenation (ECMO). Since the cannula within the ECMO circuit is associated with hemolysis-inducing shear stresses, real-world internal fluid flow measurements are urgently needed to understand the mechanism and confirm computational estimates. This study appears to be the first experimental study of fluid flow inside commercial ECMO dual-lumen cannulas (DLCs) and first particle image velocimetry (PIV) visualization inside a complicated medical device.
