“…It was sterilized with propiolactone before testing catheters because of the presence of heat sensitive materials [28]. Before biological testing, untreated and silver treated catheters were UV sterilized for 1 h. The washing system was sealed to avoid contaminations coming from the external environment.…”

The growing resistance of many strains of bacteria to antibiotics and antiseptics is becoming a serious problem in medicine. Nano-silver is one of the most prominent products in medicine because it exhibits unusual physicochemical properties and a strong biological activity. In this work an innovative silver deposition technology was applied to temporary polyurethane catheters for haemodialysis. The working conditions of catheters were reproduced through laboratory equipment that ensured the flow of deionized water and simulated body fluid inside the lumina at corporeal temperature. The growth and the adhesion of Staphylococcus aureus on the surface of the device were studied through fluorescence microscopy. ICP-AES was adopted to calculate the amount of silver released from the substrate. The stability of the coating during the whole working life of the device was demonstrated through thermo-gravimetric analysis.

“…On each sampling occasion two of the veneers were used for determining the colonists, whilst the rest were immersed in a 1% aqueous solution of p-propiolactone for 6 h to sterilize them (Hazeu and Hueck 1965). This method of sterilization was chosen to minimize the changes in the physical and chemical nature of the wood.…”

Several species of wood veneer, including some in a green undried state, were buried in various soils, and at intervals the colonists were isolated and identified. In addition, veneers were deteriorated for different periods of time, sterilized, and then reburied in the same soil. Isolates were obtained before sterilization and compared with those found afterwards. In each case the colonization involved a small number of microfungi and, because similar species were repeatedly isolated, an absence of succession under laboratory conditions was indicated. Deteriorating cubes of weed were periodically assayed for their glucose content, pH of exudates, and the release of microbial cellulase and amylase. A lack of any consistent change in colonist activity, with respect to these factors, again indicated an absence of stages during decay. The colonization pattern was contrasted with successions described in previous studies and the simplest explanation was given for the differences found.
