Density and phase-purity of α-TCP obtained by sintering of nano-crystalline powder

Dense and polished samples are sometimes used to test the in vitro biological response of biomaterials. However, their production can be challenging, for example for α-tricalcium phosphate (α-TCP), a commonly-used bone graft substitute. In this particular ...

Determination of server location in emergency care systems: an index proposal using data envelopment analysis and the hypercube queuing model

Caio Vitor Beojone

The objective of this article is to propose a new composite index (CI) that helps to determine the most effective location of servers in an Emergency Care System (ECS), using Benefit of the Doubt (BoD)/Data Envelopment Analysis (DEA) and the Hypercube queu ...

Effect of minor amounts of beta-calcium pyrophosphate and hydroxyapatite on the physico-chemical properties and osteoclastic resorption of beta-tricalcium phosphate cylinders

Paul Bowen, Gabrielle Anne Laguisma Sblendorio

beta-Tricalcium Phosphate (beta-TCP), one of the most used bone graft substitutes, may contain up to 5 wt% foreign phase according to standards. Typical foreign phases include beta-calcium pyrophosphate (beta-CPP) and hydroxyapatite (HA). Currently, the ef ...

Learning-related congruent and incongruent changes of excitation and inhibition in distinct cortical areas

Carl Petersen, Sylvain Crochet, Romain Guiet, Vahid Esmaeili, Yanqi Liu, Georgios Foustoukos, Keita Tamura, Anastasiia Oryshchuk, Reza Asri

Excitatory and inhibitory neurons in diverse cortical regions are likely to contribute differentially to the transformation of sensory information into goal-directed motor plans. Here, we investigate the relative changes across mouse sensorimotor cortex in ...

Estimation of PKC delta autophosphorylation in U87 MG glioma cells: combination of experimental, conceptual and numerical approaches

Jaroslava Joniová, Veronika Huntosova

Golgi apparatus (GA) is a center for lipid metabolism and the final target of ceramide pathway, which may result in apoptosis. In this work localization of highly hydrophobic hypericin is followed by time-resolved imaging of NBDC6 (fluorescent ceramide) in ...

On the mechanical characteristics of a self-setting calcium phosphate cement

John Botsis, Luis Pablo Canal Casado, Dimitrios Karalekas, Alexios Bimis

Objective: To perform a mechanical characterization of a self-setting calcium phosphate cement in function of the immersion time in Ringer solution. Materials and methods: Specimens of self-setting calcium phosphate cement were prepared from pure alpha-TCP ...

Fully printed 3 microns thick dielectric elastomer actuator

Herbert Shea, Samuel Rosset, Alexandre Poulin

In this work we present a new fabrication technique to print thin dielectric elastomer actuators (DEAs), reducing the driving voltage below 300 V while keeping good actuation performance. With operation voltages in the kV-range, standard DEAs are limited i ...

Spie-Int Soc Optical Engineering2016

Background: Total (i.e. free + sulfated) metanephrines in plasma is a biomarker for the diagnosis of pheochromocytoma/paraganglioma. Sulfated metanephrines must be completely deconjugated by perchloric acid hydrolysis or sulfatase treatment prior to analyt ...

The Insecticide Imidacloprid Causes Mortality of the Freshwater Amphipod Gammarus pulex by Interfering with Feeding Behavior

Kristin Schirmer

If an organism does not feed, it dies of starvation. Even though some insecticides which are used to control pests in agriculture can interfere with feeding behavior of insects and other invertebrates, the link from chemical exposure via affected feeding a ...

Overexpression of parkin in the rat nigrostriatal dopamine system protects against methamphetamine neurotoxicity

Bernard Schneider

Methamphetamine (METH) is a central nervous system psychostimulant with a high potential for abuse. At high doses, METH causes a selective degeneration of dopaminergic terminals in the striatum, sparing other striatal terminals and cell bodies. We previous ...
