hypoxia is a major concern for human health. multiple new techniques were proposed for tissue oxygenation in different variety of patients. clark jr. et al. presenting their article titled “fluorovent: a new perfluorocarbon for liquid ventilation”, at a symposium in neonatology, in 1995, described the scientific importance for perfluorocarbons which would be ideally suited for use in liquid ve...
BACKGROUND The present study was set up to evaluate the influence of perfluorocarbon liquids on the postoperative anatomical and functional results as well as on the complication rates in eyes with proliferative vitreoretinopathy (PVR). METHODS Sixty five consecutive eyes (64 patients) with PVR in different stages requiring surgical intervention where liquid perfluorocarbons were used were co...
BACKGROUND A number of studies have demonstrated the effectiveness of liquid ventilation with perfluorocarbons in improving pulmonary function in acute respiratory distress syndrome. Although it is known that perfluorocarbon-associated gas exchange facilitates lung mechanics and oxygenation, the complete mechanism by which perfluorocarbons exert their beneficial effects in acute lung injury sti...
Introduction Tumor hypoxia is well known to reduce cancer treatment efficacy [1]. Hypoxic tumor cells, which have decreased oxygen levels (pO2), are more resistant to radiotherapy and chemotherapy. Dissolved oxygen influences the F magnetic resonance relaxation times of perfluorocarbons [2]. This property has been used in semiquantitative animal studies to image tumor oxygenation [3]. In this s...
In spite of their interest, viscosities of fluorocarbon compounds are scarce, and the available data are unreliable and of poor accuracy. In this work, viscosity measurements of linear, cyclic, aromatic, and R-substituted perfluorocarbons were carried out in the temperature range between (298.15 and 318.15) K using an Ubbelohde viscometer. The experimental results show that fluorinated compound...
Research of blood substitute formulations and their base materials is of high scientific interest. Especially fluorinated microemulsions based on perfluorocarbons, with their interesting chemical properties, offer opportunities for applications in biomedicine and physical chemistry. In this work, carbon K-edge absorption spectra of liquid perfluoroalkanes and their parent hydrocarbons are prese...

The fluorinated double-tailed triblock surfactant 1-Na represents a new type of gelator for perfluorocarbons which can gelate at low concentration (1.5 wt%) both bromoperfluorooctane and perfluorodecalin, two of the most appealing perfluorinated fluids for pharmaceutical applications.
