tween as a substitute for diethyl ether in the formalin-ether sedimentation technique
background: tween as a substitute for diethyl ether in the formalin-ether sedimentation technique was evaluated for parasite detection. methods: fresh fecal material free of parasites with 10% formalin to prepare standardized specimen was thoroughly pooled. this specimen was divided into 5 equal portions; one was without infection, and each of the others was individually seeded with entamoeba ...
متن کاملProteoglycans: the "Teflon" of the airways?
Proteoglycans are a family of structurally distinct, polyanionic complex carbohydrates composed of repeating disaccharide units. Proteoglycans include heparin, heparan sulphate, chondroitin 4-sulphate, chondroitin 6-sulphate, dermatan sulphate, and hyaluronic acid. Heparin is found in the granules of a subset of mast cells where it is bound to various mediators including histamine. Heparan sulp...
متن کاملWhole-Teflon microfluidic chips.
Although microfluidics has shown exciting potential, its broad applications are significantly limited by drawbacks of the materials used to make them. In this work, we present a convenient strategy for fabricating whole-Teflon microfluidic chips with integrated valves that show outstanding inertness to various chemicals and extreme resistance against all solvents. Compared with other microfluid...
متن کاملHollow alumina nanospheres as novel catalyst for the conversion of methanol to dimethyl ether
This paper investigates hollow and porous alumina nanospheres that were previously synthesized to be used for the dehydration of methanol to dimethyl ether (DME). As hollow nanostructures possess characteristics such as low density and high surface to volume ratio, their catalytic activity between hollow and porous structure is compared. For this purpose, three most important parameters (acidit...
متن کاملThe use of Teflon as a dural substitute and its other neurosurgical applications.
During the last seven decades many materials have been experimentally tried as dural substitutes, and many have been discarded after being clinically introduced. In recent years, satisfactory results from Orlan (Huertas, 1955), Vinyon 'N' (Teng and Feigin, 1955; Teng, 1961), and homologous dura mater (Crawford, 1957; Campbell, Bassett, and Robertson, 1958) as dural substitutes have been reporte...
