The influence of the molecular weight carboxymethylcellulose as solid binder for additive manufacturing was studied. Three sodium carboxymethyl celluloses with different weights were added to a stoneware. powders used on jetting machine using water-based liquid bonding agent. Differential Thermal Analysis and Fusion Tests (Hot Stage Microscope) carried out determine correct firing cycle. printe...

The mechanical performance of the cement-in-cement interface in revision surgery has not been fully investigated. The quantitative effect posed by interstitial fluids and roughening of the primary mantle remains unclear. We have analysed the strength of the bilaminar cement-bone interface after exposure of the surface of the primary mantle to roughening and fluid interference. The end surfaces ...

In this paper a report is made of the chromatographic behavior of growth hormone on columns of carboxymethylcellulose and diethylaminoethylcellulose. Ion exchange chromatography on the synthetic resin, Amberlite IRC-50, has been utilized to purify and to assess the homogeneity of a number of proteins. This resin has been used in chromatographic studies on cytochrome c (l), ribonuclease (2), lys...

HYPOTHESIS The use of certain surgical adhesion reduction devices where there is a risk of concomitant bacterial contamination potentiates intra-abdominal infection. DESIGN Evaluation of adhesion reduction devices in an experimental model of intra-abdominal infection. SETTING Experimental animal model. INTERVENTIONS Adhesion reduction devices were administered at the time of bacterial cha...

This study discusses efforts made to design drug-delivery system based on superporous hydrogel composite for sustained delivery of ranitidine hydrochloride. The characterization studies involve measurement of apparent density, porosity, swelling studies, mechanical strength studies, and scanning electron microscopy. Scanning electron microscopic images clearly showed the formation of interconne...

A cDNA expression library of the rumen fungus Neocallimastix patriciarum was made in Escherichia coli. Cellulolytic clones were identified by screening on a medium containing carboxymethylcellulose. Restriction mapping and Southern hybridization analysis of selected clones revealed three distinct cellulase cDNAs, designated celA, celB and celC. Studies on the substrate specificity showed that t...
