    Abstract: A dental floss device (1, 40, 50, 60, 70) comprises a handle (2) having a shank (3) terminating in a head piece (4). A disposable dental floss holder (5) comprises a base portion (10) and a pair of spaced-apart jaws (11, 12) with a length of dental floss (13) extending therebetween. The head piece (4) has a groove (20) in which the base portion (10) is securely retained when the device is used in all flossing directions. Snap-fit projections (15) extend inwardly from the jaws (11, 12) of the floss holder (5) and are retained behind marginal edges (25) of a floor (24) of the groove (20). When used, the floss holder (5) is removed and a new floss holder (5) is fitted.

    Abstract: A method for rapidly detecting the presence or absence of a particular nucleic acid sequence at a candidate locus in a target nucleic acid sample comprises the steps of: i) introducing a modified base which is a substrate for a DNA glycosylase into said candidate locus at one or more preselected positions; ii) excising the modified base by means of said DNA glycosylase so as to generate an abasic site; iii) cleaving phosphate linkages at abasic sites generated in step ii); and iv) analysing the cleavage products of step iii) so as to identify in said target nucleic acid sequence the presence or absence of said particular nucleic acid sequence at said candidate locus. The method has particular application for detecting specific mutations in a DNA sample, including the detection of multiple known mutations in DNA. Large throughput of sample can be achieved rapidly and easily.

    Abstract: An ac/dc converter (1) has a closed loop controller (3) to maintain a well regulated output voltage (Vo) with low peak-to-peak ripple. A resonant capacitor (Cin) across the rectifier bridge (DR1-DR4), and a resonant inductor (LR) between the bridge and the isolation transformer provide inherent power factor correction. A clamping diode (Dcl) is connected between the dc rectifier bridge positive terminal and the bulk capacitor (CB). There is also a second resonant capacitor (Ct) across the isolation transformer. There is zero voltage switching of the power switches (Q1, Q2)
