Industrial Uses Of Phosphonates
Published in Richard L. Hilderbrand, The Role of Phosphonates in Living Systems, 2018
George L. Drake, Timothy A. Calamari
Pressure sensitive adhesives for plastics can be prepared by mixing vinyl carboxylatedialkyl vinyl phosphonate copolymer with a natural or synthetic resin. Such polymers bond polyethylene, polypropylene, polyterephthalate, rigid and plasticized poly(vinyl chloride), superpolyamide, cellulose triacetate, and poly (vinyl chloride)-coated cellulosic film to glazed and bleached craft paper. Bonding remains effective over 6 months at 50°C.3
Introduction
Published in Gad Shani, Radiation Dosimetry, 2017
For high-dose measurement the following dosimeters are used: calorimeters, alanine/electron spin resonance (ESR) systems, liquid solutions (Fricke, ceric-cerous, dichromate), and polymer systems (polymethyl methacry-late, cellulose triacetate, radiochromic films and optical waveguides).
Evolution of Hemodialysis Technology
Published in Sirshendu De, Anirban Roy, Hemodialysis Membranes, 2017
Several companies brought out products based on acetylated cellulose. Althin/Toyobo introduced the first CA-based membranes. These were the most hydrophilic in the CA family but were also the least biocompatible. Hospal/Althin brought out cellulose diacetate membranes. They were more biocompatible, had higher KUF, and could be sterilized with γ-radiation and ETO. But these membranes were more hydrophobic than CA and hence were prone to protein fouling and could not be sterilized with steam. Akzo/Toyobo used cellulose triacetate with 14–30 μm wall thickness, having higher KoA and KUF for both small- and middle-molecular-weight solutes. The membranes were suitable for HDF under convective mode. They could be sterilized with γ-radiation and ETO but could not be sterilized with steam.
Milky fluid elicited by cellulose triacetate membrane dialyzer, hyperlipidemia, and elevated C-reactive protein

A 47-year-old man with malignant lymphoma and secondary membranous nephropathy was admitted to our hospital due to fever and dyspnea. He was diagnosed as having Pneumocystis pneumonia, and treatment with sulfamethoxazole and trimethoprim was begun. His renal function gradually deteriorated during the course of the treatment, and hemodialysis was thus initiated using the cellulose triacetate membrane dialyzer. Hemodialysis was stably performed at first two sessions, but pneumonia worsened. In spite of no changes in the hemodialysis settings and conditions, milky fluid appeared on the venous side of the hemodialysis circuit, when the blood was returned with 0.9% saline at the end of the third session of hemodialysis (Figure 1). The fluid in the arterial side of the circuit kept clear. We stopped returning of the blood immediately.

FX CorDiax 40 dialyzer cartridges containing polysulfone/polyvinylpyrrolidone filters (FXC) and Dialysis exchange-set (DES), i.e., bypass tubing without membrane, were from Fresenius Medical Care (Bad Homburg, Germany). SureFlux-15UX cartridges, containing cellulose-triacetate filters (NSF), was from Nipro Corporation (Osaka, Japan). Forane (isoflurane) was from Rompharm (Otopen, Romania), and zymosan from Sigma-Aldrich (Budapest, Hungary).

Ps and Eb values of the GG and P films designed in this work were, generally, much higher than those reached for other films based on other polysaccharides as mucoadhesive cellulose triacetate films (Ribeiro et al. 2016), resistant starch/pectin films (Meneguin et al. 2014), resistant starch/pectin films reinforced with nanocellulose and cross-linked high amylose/pectin films (Prezotti et al. 2012).
