Dimethylpolysiloxane-reinforced film in a membrane oxygenator
Biomedical Engineering, 1977With the purpose of diffuse membranous oxygenation of blood the possibility of employing a Soviet-made dimethylpolyxyloxane-reinforced film "Sigma" was investigated. The test-trials were carried out with a membranous oxygenator of the "Sandwich" type.

The determination of dimethylpolysiloxane in beer and yeast
The Analyst, 1971An infrared method that provides an estimate of the silicone content of beer and yeast has been developed. Because of the increased sensitivity over other reported methods it is possible to use smaller samples, which could be an advantage with biological material. The recommended working concentration range is 0·2 to 2 mg 1–1.

Low temperature separation of trace amounts of dimethylpolysiloxanes from food
Journal of the American Oil Chemists' Society, 1969AbstractDimethylpolysiloxanes, which are difficult to determine in fatty foods, can be separated at low temperatures by special freeze‐out apparatus. Final determination is made by atomic absorption, visible or ultraviolet spectrometry. Recoveries from cottonseed oil and cake mix ranged from 95% to 110%.

cAMP Levels in Reactive Tissues Around Dimethylpolysiloxane Solid Implants
Plastic and Reconstructive Surgery, 1985By the aid of radioimmunologic assay, the authors measured the cAMP content of the reactive capsules around solid dimethylpolysiloxane implants in mice at different times; they also measured the same substance in some human connective tissues (granulation tissue and normal dermis) and compared together all the values they obtained.

Thin-film deposition by laser ablation of dimethylpolysiloxane
Applied Surface Science, 2002Abstract Transparent, well-insulated SiO2 thin films were deposited at room temperature by pulsed laser deposition with a dimethylpolysiloxane target. It could be asserted with confidence that the films deposited at the oxygen gas pressure of 4.4×10−2 Torr were to be SiO2 by X-ray photoelectron spectroscopy (XPS). The XPS analyses also supported that

Effect of A Dimethylpolysiloxane Fluid on the Stability of Menadione
Journal of Pharmaceutical Sciences, 1968The nonaqueous solvents presently in use as parenteral vehicles possess certain disadvantages or have limited application. The silicone fluids have certain physical, chemical, and biological properties which would appear to make them suitable for parenteral formulations.

Forensic Examination of Toxicological Specimens for Dimethylpolysiloxane (Silicone Oil)
Journal of Analytical Toxicology, 1977Silicone oils (dimethylpolysiloxanes) may not be as biologically inert as has been generally accepted. When injected intravenously the toxicity is, in part, a function o! viscosity. A case of probable acute toxicity resulting from injection of silicone oil and the analysis of fixed tissues therein are described.

Adsorption properties of amphiphilic polyoxyalkylenated dimethylpolysiloxane derivatives on keratin
Journal of Surfactants and Detergents, 2001AbstractAdsorption properties of two types of dimethylpolysiloxane backbone derivatives, perfluoroalkyl polyoxyethylenated dimethylpolysiloxane (FPD) and polyoxyethylenated dimethylpolysiloxane (PD), onto keratin surfaces were investigated. Both polymers are amphiphilic, since they possess hydrophilic polyoxyethylene groups.

Foreign body reaction to dimethylpolysiloxane (Sila stic): report of case
The Journal of the American Dental Association, 1967This report reiterates the need to elicit a detailed history. In this instance, a 42-year-old woman had a biopsy of what was actually a foreign body-type granuloma reaction to multiple injections of dimethylpolysiloxane in the affected region.

Chemical modification of dimethylpolysiloxane for enhancement of CO2 binding enthalpy
Physical Chemistry Chemical Physics, 2023We have applied a variety of chemical modifications to polydimethylsiloxane (PDMS) and found that the introduction of earth metal elements is the most effective way to enhance the interaction between PDMS and CO2.
