The use of polyvinyl chloride gloves containing di(2-ethylhexyl) phthalate for food contact applications is restricted. In their place, polyvinyl chloride gloves containing non-phthalate plasticizers (PVC-NP) have been introduced. They contained unknown substances, so they were studied by GC/MS, HR-MS and NMR. The chemical structures of the unknown substances were confirmed to be diethylene gly...

We appreciated the research by Derdeyn et al (1) from the Mallinckrodt Institute of Radiology concerning the size and suspension characteristics of polyvinyl alcohol (PVA) particles. We do agree that both size and suspension characteristics of PVA represent relevant parameters affecting the aggregation of particles during injection. In addition to these two variables, we considered further para...

Nano-fibrillated cellulose was produced from flax and wheat straw cellulose pulps by high pressure disintegration. The reinforcing potential of both disintegrated nano-celluloses in a polyvinyl-alcohol matrix was evaluated. Disintegration of wheat straw was significantly more time and energy consuming. Disintegration did not lead to distinct changes in the degree of polymerization; however, the...

BACKGROUND Adhesions follow abdominal surgery with an incidence as high as 95%, resulting in invalidating complications such as bowel obstruction, female infertility, and chronic pain. Searches have been performed for a safe and effective adhesion barrier; however, such barriers have impaired anastomotic site healing. The primary aim of this study was to investigate the effect of a new adhesion...

Biocompatible synthetic polymers are largely used in the bio-medical domain, tissue engineering and in controlled release of medicines. Polymers can be used in the achievement of cardiac and vascular devices, mammary implants, eye lenses, surgical threads, nervous conduits, adhesives, blood substitutes, etc. Our study was axed on the development of cytotoxicity tests for 3 synthetic polymers, n...

This study was performed to compare the amount of air leakage into the thoracic cavity associated with three thoracostomy tube materials (silicone, polyvinyl chloride, red rubber) in canine cadavers. Differences in intrapleural pressures (IPPs) measured before and after tube placement and before and after tube removal were calculated. The duration of air leakage around the tubes was assessed by...
