Abstract: Methods of assessing the risk of clinical signs of hypersensitivity reaction to nucleoside antiviral compounds, including abacavir, are described. The methods include genotyping subjects for polymorphisms in the TNF? gene, the class 1 HLA genes, or a combination of both the TNF? and HLA genes.

Abstract: Disclosed is a method and apparatus for gel electrophoresis which simultaneously employs two or more electric fields in a single gel. According to this invention, which is defined as Multiple-Zone Pulsed-Field Gel Electrophoresis (MZPFGE), the electric field is set to different values in two or more spatially distinct regions of the gel. The difference in values may be related to time dependence, field amplitude or both.

Abstract: An apparatus for separating particles within a medium which is capable of generating electric fields having adjustable magnitudes and orientations is disclosed herein. The electrophoretic apparatus of the present invention includes electrode arrangement for providing a plurality of sets of opposing individually responsive electrodes for generating electric fields within the medium, each field having at least one magnitude and direction. The invention further includes a control circuit for selectively controlling electrodes within the electrode sets to vary the magnitudes and directions of the electric fields at locations within the medium. The electric fields induce differing rates of motion of the particles thereby separating the particles.

Abstract: A single flip flop is integrated with MOS circuitry which enables the single flip flop to be triggered by each of several individual clocked functions without interfering with one another. The flip flop responds only to low to high transitions of each clock signal input. This is accomplished by feeding back the flip flop output to each trigger circuit in such a way as to temporarily disconnect the trigger circuit from the flip flop during the time period between two successive low to high transitions of a particular clock signal, so that the flip flop can be triggered by other clocked functions without interference from the particular clock signal.
