Abstract: The invention is drawn to isolating sequence variants of a genetic locus of interest using a modified iterative primer extension method. The nucleic acids analyzed are generally single stranded and have a reference sequence which is used as a basis for performing iterative single nucleotide extension reactions from a hybridized polymerization primer. The iterative polymerization reactions are configured such that polymerization of the strand will continue if the sequence of the nucleic acid being analyzed matches the reference sequence, whereas polymerization will be terminated if the nucleic acid being analyzed does not match the reference sequence. Nucleic acid strands that have mutations can be isolated using a variety of methods and sequenced to determine the precise identity of the mutation/polymorphism. By performing the method on both strands of the nucleic acid being analyzed, virtually all possible mutations can be identified.
Abstract: A biosensor strip having a low profile for reducing the volume of liquid sample needed to perform an assay. In one embodiment, the biosensor strip includes an electrode support; an electrode arrangement on the electrode support; a cover; a sample chamber; and an incompressible element placed between the cover and the electrode support, the incompressible element providing an opening in at least one side or in the distal end of the sample chamber to provide at least one vent in the sample chamber. In another embodiment, the biosensor strip has an electrode support; an electrode arrangement on the electrode support; a cover; and a sample chamber, the cover having a plurality of openings formed therein, at least one of the openings in register with the sample chamber. The invention further includes methods for preparing such a biosensor strips in a continuous manner.

Abstract: A measurement module for glucose testing includes a glucose testing measurement module housing, a test strip receptacle formed in the housing, and a connector portion formed in the housing and shaped to permit mechanical removable attachment of the housing to a hand-held computer. Electronics determine the amount of glucose present in a sample of body fluid, when the test strip is positioned in the receptacle and the body fluid is placed on a test strip, and communicate the glucose amount to the hand-held computer via the connector portion.

Abstract: A significantly increased amount of a monoclonal antibody is obtained from the culture medium of recombinant hybridoma prepared by introducing genes encoding a protein identical to the immunoglobulin heavy chain polypeptide of the specific monoclonal antibody into an immortalized B cell (hybridoma) producing the monoclonal antibody.
Abstract: A meter and sensors, for use in combination, where no calibration code has to be entered by the user or is read by the meter. The meter is configured with a predetermined slope and y-intercept built into the meter. If the slope and y-intercept of the sensor are within a predetermined area or grid, or otherwise close to the slope and y-intercept of the meter, the batch of sensors is acceptable for use with that meter for providing accurate analyte concentration results.
Abstract: The present invention provides methods of modulating angiogenesis in an individual, as well as methods of identifying a candidate agent that modulates angiogenesis, where such methods involve modulating and identifying agents that modulate expression of gene products of a subset of genes concordantly-regulated by agonists of nicotinic acetylcholine receptor (nAChR), bFGF receptor, and VEGF receptor.

Abstract: An electrode assembly for use in an iontophoresis device for the transcutaneous administration of an active therapeutic species has a base layer of including a linking conductive base material which is consumed (oxidizes or reduces) preferentially to water, a first upper layer of sacrificial material coated on a first portion of the base layer wherein the sacrificial material is consumed preferentially to the linking conductive base material of the base layer. A second upper layer of non-conducting material is coated on a second portion of the base layer, the second upper layer being spaced from the first upper layer, connected by a narrow exposed linking area of the base layer material remaining exposed therebetween.
Abstract: In certain embodiments, the present invention relates to methods, compositions, and kits for diagnosing autoimmune chronic urticaria.

Abstract: Disclosed are embryonic stem cell-derived dendritic cells, genetically modified immature dendritic cells capable of maturation, as well as methods for the production of such cells. In one embodiment, the cells made be produced by a method comprising the steps of providing a population of embryonic stem cells; culturing the embryonic stem cells in the presence of a cytokine or combination of cytokines which brings about differentiation of the embryonic stem cells into dendritic cells; and recovering the dendritic cells from the culture. In a further embodiment, the cells may be genetically modified.

Abstract: Disclosed herein are computer-implement systems and methods for identifying and analyzing content (e.g., text, images, videos, etc.) published on digital content platforms (e.g., webpages, mobile applications, etc.). Such analysis is then used to determine whether the published content is appropriate for association with (or “hosting of”) a third-party's content. In one embodiment, for example, the systems and methods presented are particularly useful for determining the appropriateness of an image published on a digital content platform, prior to providing an advertisement proximate the image. As such, merchants can avoid associating their advertised products/services with vulgar, obscene, or otherwise inappropriate images that may have a negative impact on their brand or reputation.

Abstract: The invention features compounds of the general formula: B-L-M where B is a binding agent capable of selectively binding to a nerve cell surface receptor and mediating absorption of the compound by the nerve cell; M is a moiety which performs a useful non-cytotoxic function when absorbed by a nerve cell, and can be a therapeutic moiety or an imaging moiety; and L is a linker coupling B to M. The invention also features methods of use of the compounds in, for example, treating conditions such as viral infections and pain, as well as in labeling nerve cells.
