Appl. No.:

09/862417

Inventors:

Xiao Bing Wang - Lutherville MD 21093

International Classification:

C12Q 168

US Classification:

435 6, 435 71, 435 911, 435 912, 4352872, 536221, 536 231, 536 243, 536 2431, 536 2432, 536 2433

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
C12P019/34

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.

International Classification:

C12N 15/10
C12Q 1/6853

Abstract:

One embodiment provides methods to identify known and unknown gene fusions by creating a cDNA circle and analyzing the circle cDNA by amplification or sequencing. The circle cDNA is created in two approaches: 1) reverse transcribe a target RNA to cDNA, ligate the 3′end of the cDNA to its 5′ end to form a circle cDNA, or 2). ligate the 3′ end of target RNA to its 5′ end to form a circle RNA, reverse transcribe the RNA to a cDNA, and ligate the cDNA to form a circle cDNA. The circle cDNA is amplified using a primer designed from a known sequence of a wild type target gene by rolling circle amplification or PCR methods. The known or unknown fusion gene sequences in the circle cDNA are amplified and identified by sequencing analysis.

Abstract:

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may detect a beam failure associated with a component carrier (CC) of a plurality of CCs that are aggregated. The UE may identify, based at least in part on detecting the beam failure, a CC group in which the CC and one or more other CCs, of the plurality of CCs, are included. The UE may transmit, to the BS, a beam failure recovery request (BFRQ) communication associated with the CC group. Numerous other aspects are provided.
