Abstract: Methods and devices for nasopharyngeal carcinoma screening are disclosed. The method comprises providing a nasopharyngeal sample from a subject, isolating DNA from the sample, amplifying and detecting at least one EBV target sequence from the DNA using real-time PCR, wherein a real time PCR cycle threshold number of less than or equal to 31.5 is indicative of the subject having nasopharyngeal carcinoma or a risk of developing nasopharyngeal carcinoma.

Abstract: Devices for receiving fluid such as water are described. Principally (although not necessarily exclusively) designed for use as chlorinators, the devices may divert water flowing in conduits into the devices for treatment and subsequent return to the flow stream. A device may connect to a pipe without tools and require only one hole to be formed in a pipe wall.

Abstract: This invention relates to a vessel suitable for insertion as a by-pass into new or pre-existing fluid flow paths, such as water lines for swimming pools. The vessel is adapted to receive and contain a wide variety of different types of equipment, which can typically be in the form of a cartridge, and contact the fluid passing through the vessel with the equipment in a way that reduces or minimizes the effect of pressure spikes in the water line, and more efficiently moves the water through the vessel and back into the fluid flow path or conduit. The invention also relates to a method for treating fluids using such a vessel.

Abstract: The invention relates to an apparatus for electrolytic purification, comprising: (a) a pressure vessel having at least one access opening, at least one fluid flow inlet, and at least one fluid flow outlet, wherein the fluid flow inlet and fluid flow outlet are in fluid communication with a chamber inside the pressure vessel; (b) an removable electrode assembly, at least a portion of which is disposed within the chamber inside the pressure vessel, comprising: a plurality of substantially parallel spaced planar electrodes, an electrical coupling between the electrode plates and a voltage source, and a radially extending circumferential sealing plate substantially normal to the planes of the electrodes, disposed near the electrical coupling, adapted to prevent fluid flow from the chamber to the electrical coupling; (c) a removable locking ring, comprising: a proximal portion adapted to removably attach to the access opening of the pressure vessel and retain the radially extending circumferential sealing plate of
