Abstract: The present invention provides for techniques for transporting materials using electrokinetic forces through the channels of a microfluidic system. The subject materials are transported in regions of high ionic concentration, next to spacer material regions of high ionic concentration, which are separated by spacer material regions of low ionic concentration. Such arrangements allow the materials to remain localized for the transport transit time to avoid mixing of the materials. Using these techniques, an electropipettor which is compatible with the microfluidic system is created so that materials can be easily introduced into the microfluidic system. The present invention also compensates for electrophoretic bias as materials are transported through the channels of the microfluidic system by splitting a channel into portions with positive and negative surface charges and a third electrode between the two portions, or by diffusion of the electrophoresing materials after transport along a channel.

Abstract: Methods, apparatus and systems are provided for introducing large numbers of different materials into a microfluidic analytical device rapidly, efficiently and reproducibly. In particular, improved integrated pipettor chip configurations, e.g. sippers or electropipettors, are described which are capable of sampling extremely small amounts of material for which analysis is desired, transporting material into a microfluidic analytical channel network, and performing the desired analysis on the material.

Abstract: A filler material for a surgically implantable prosthesis comprised of a synthetic triglyceride having a viscosity substantially greater than that of naturally occurring triglycerides is provided. The triglyceride composition is formed of saturated alkyl chains to reduce or limit the potential for oxidation of the alkyl chains to form peroxide groups which adversely affect the biocompatibility of the filler material and the implant. Preferably, the filler material has a viscosity substantially the equivalent of a normal human breast. The synthetic triglyceride filler material may also have a lower viscosity which is a liquid at room temperature for use in inflatable devices. Prostheses containing filler material having the desired viscosity and antioxidation characteristics are also provided as well as a method for preparing the filler material.

Abstract: The present information management system for personal health digitizers. This system provides a centralized database that collects and stores monitoring data from a large number of individuals who are termed “consumers” herein. The information management system for personal health digitizers includes processing elements that can be used to perform statistical analysis of the collected data on a per consumer, population segment, or query specific basis. The analysis function is made available to various classes of “users” which classes can include consumers, medical practitioners, health care providers, institutions, and the like. The database is architected in a hierarchical manner to enable the users to access only the relevant, prepartitioned segment of the collected data that this particular class of user is authorized to analyze.

Abstract: The invention concerns a reagent composition that employs at least two different terminators of a nucleic acid template-dependent primer extension reaction to determine the identity of a nucleotide base at a specific position in a nucleic acid of interest. The invention also concerns an immobilized method for determining such identification. The invention may be used to determine the presence or absence of a specific nucleotide sequence in a sample. It may also be employed in determination of genotype and in the identification of different alleles.

Abstract: An extension cord holder includes a handle; a main post having top and bottom ends, the main post being connected to the handle at the top end; and, front and rear cord retention arms extending upwardly from the bottom end of the main post to define front and rear upwardly opening slots, each slot sized and shaped for receiving a plurality of loops of an extension cord. An extension cord may be loaded onto the holder by positioning successive loops from a mid point of the cord to the male end of the cord into one slot and from the mid point of the cord to the female end of the cord into the other slot. Deployment of the male and female ends of the cord may be achieved in reverse order.
