International Classification:

H04Q 700

US Classification:

370332, 370335, 370342, 455437, 455443

Abstract:

Inter-frequency handoffs in a CDMA or other wireless communication system are controlled using a noise-limited coverage trigger metric which is able to distinguish between same-frequency cell boundaries and other-frequency cell boundaries in the system. The trigger metric may be generated as a function of an average signal-to-noise measure for pilot signals received at a mobile station of the system and a linear sum of the signal-to-noise measures. The signal-to-noise measures may be generated in the mobile station and included in messages transmitted from the mobile station to one or more base stations of the system. The trigger metric is used to control a handoff from a current frequency to a new frequency in an ongoing call. The trigger metric may alternatively be based on a measure of mobile receive power alone. Other aspects of the invention reduce unnecessary searching for a new frequency and decrease the likelihood of âping-pongingâ from a current frequency to a new frequency by providing additional checks in the handoff process.

International Classification:

C12Q 168

US Classification:

Abstract:

A method for detecting and/or quantifying a target DNA or RNA present in a sample by a isometric primer extension method is disclosed. The method includes carrying out a primer extension reaction in the absence of a free nucleotide so that the primer extension reaction is stopped where the absent nucleotide would have been inserted. Thus, as the amount of incorporation of a labeled nucleotide on the primer extended product is detected, the amount of the target RNA or DNA in the sample is measured.

International Classification:

A61K007/20

US Classification:

424/053000

Abstract:

The present invention provides compositions and methods for inhibiting, reducing, preventing or controlling dental caries formation. Electrolyzed water having an oxidation-reduction potential from about -150 to 0 mV measured against a platinum electrode, also known as “Trim water” can reduce, inhibit, prevent, or control caries in part by neutralizing dental plaque acid by increasing the pH in the area surrounding dental plaque. One embodiment provides contacting a tooth with electrolyzed water, typically after the tooth has been challenged with a sugar, to neutralize dental plaque acid and thereby reduce the formation of dental caries. Electrolyzed water and compositions comprising electrolyzed water can be formulated as palatable beverages, gels, candy, or other foodstuffs that are safely digested by individuals such as young children.

International Classification:

C12Q001/68

US Classification:

435/006000, 435/091200

Abstract:

Methods, compositions, and kits for the detecting and/or quantification of polynucleotides are provided. An exemplary method provides hybridizing a first primer to the target polynucleotide and forming equal length primer extension products using a nucleotide reaction mixture consisting of X, Y, and Z, wherein X and Y are different purine non-terminator nucleotides, and Z is a pyrimidine non-terminator nucleotide, or X and Y are different pyrmidine non-terminator nucleotides, and Z is a purine non-terminator nucleotide. A portion of the extension products are hybridized to a second primer that is immobilized on a solid support, and the second primer is extended with at least one nucleotide having a detectable marker. The signal from the detectable marker can be correlated to the amount of target polynucleotide. Kits for performing this method are also provided.

International Classification:

C12Q 1/68

US Classification:

435006000

Abstract:

The invention relates to a method for detecting any mutation at a predetermined site occurring in a known nucleic acid sequence. The method uses primer extension analysis to detect the mutation. Unlabeled terminator is supplied along with labeled non-terminator in the primer extension reaction to detect whether the first nucleic acid base on the template strand that is directly opposite the nucleic acid base immediately 3′ to a primer is a mutant. In the primer extension reaction, the terminator is complementary to the wild-type base on the template strand that is directly opposite the nucleic acid base immediately 3′ to the primer. Non-terminators are the other nucleotides and are labeled. When the terminator is incorporated into the primer extension strand, primer extension reaction terminates. Incorporation of a labeled non-terminator in the primer extension strand indicates that a mutation has occurred at the predetermined nucleic acid base site.
