Filtration sizes of human immunodeficiency virus type 1 and surrogate viruses used to test barrier materials.
Filters with well-defined holes were used to determine the effective diameters in buffer of human immunodeficiency virus type 1, herpes simplex virus type 1, and four bacteriophages (phi X174, T7, PRD1, and phi 6), which may serve as surrogate viruses for testing barrier materials. Bacteriophages phi 6 and PRD1 most closely model human immunodeficiency virus type 1 in filtration size.
متن کاملDye to use with virus challenge for testing barrier materials.
Can FD&C Blue no. 1 dye photoinactivate bacteriophages phi X174, T7, PRD1, and phi 6 under laboratory lighting conditions? At high levels of light, the dye (500 microM) photoinactivated only phi 6. Thus, this dye can be used at concentrations up to 500 microM with bacteriophages phi X174, T7, and PRD1 to test barrier material integrity.
متن کاملRoughness Model for Adhesion Testing of Pharmaceutical Coating Materials
Objective Roughness is the main parameter in interlocking bonding mechanism. Yet there is no model designed to evaluate the effect of surface roughness on adhesion of coating materials in pharmaceutical sciences. Materials and Methods In this study polymethyl metacrylate spherical beads with different sizes were poured into 10 mm mold, then it was pressed by hand screw and finally heated to 141...
متن کاملImportant Factors for Selecting Food Packaging Materials Based on Permeability
One of the critical factors in selection of food packaging materials is permeability and/or transmission rate to help maintain food quality. Conditions of product/material use such as temperature and relative humidity are critical for determining optimal testing conditions to determine permeability rate. Basics of permeability, interpretation of data and relationship to selection of materials f...
متن کاملSpinal canal surrogate for testing intradural implants.
We have designed, built and tested an anthropomorphic-scale surrogate spinal canal, for use in preliminary evaluations of the performance characteristics of a novel intradural spinal cord stimulator. The surrogate employs a silicone mock spinal cord with semi-major and semi-minor diameters of 10 and 6 mm, respectively, commensurate with those of actual thoracic-level spinal cord. The axial rest...
