  One haemodialysis unit's experience of hepatitis B

  摘要：

  SummaryHaemodialysis patients are at high risk of contracting Hepatitis B Virus (HBV). This blood borne virus has been responsible for many critical incidents within haemodialysis units around the world. This paper seeks to explore one such outbreak and at the same time look more closely at HBV and connected issues. The incident discussed occurred within a haemodialysis unit situated in the Northwest of England. This paper is presented as a case study. When HBV was detected in a previously HBV negative patient a crisis management team moved quickly to contain any possible outbreak and sought to discover the origin of the infection. An outline of the personal and financial cost to the organisation, what lessons have been learnt and why recommendations have been made to immunise the local dialysis population again HBV will be presented.

  1H NMR and isothermal titration calorimetry (ITC). In chloroform solvent, hydrogen-bonding to anions is accompanied by downfield shifts in the amide NH protons of the fluorinated receptors and by evolution of heat. Association constants for 1:1 complexation (Kassoc) are >1000 M−1. An analogous hydrocarbon receptor binds weakly to anionic guests (Kassoc < 50 M−1). Ab initio calculations indicate that

  A method of making a functionalized fluorinated monomer for use in making oligomers and polymers that can be used to improve surface properties of polymer-derived systems, such as coatings. The method of making a functionalized fluorinated monomer includes reacting at least one fluorinated nucleophilic reactant, such as a fluorinated alcohol, with at least one compound containing at least one epoxide group. Other methods include reaction of a fluorinated alcohol with a cyclic carboxylic anhydride. In another embodiment, a method includes reacting a fluorinated mesylate, tosylate or triflate with an amine, alkoxide or phenoxide. In other embodiments, the method includes reacting a fluorinated alcohol with an alkyl halide, or reacting a fluorinated alkyl halide with an amine. The functionalized fluorinated monomers may be used as intermediates and reacted to modify the functional groups thereon. Further, the functionalized fluorinated monomers may be reacted to form polymers or oligomers, or with polymers or oligomers having functional groups to modify the polymer or oligomer through the functional group thereon,
