  • Publication number: 20100298585
    Abstract: A method for the synthesis of dienogest from 3-methoxy-estra-1,3,5-trien-17-one includes the steps of a) reacting 3-methoxy-estra-1,3,5-trien-17-one with alcohol in the presence of an acid in an organic solvent to form 3-methoxy-17,17-dialkoxy-estra-1,3,5-triene; b) subjecting the product of step a) to partial reduction by reaction with alkali metal in liquid ammonia; c) treating the product of step b) with mild acid; d) reacting the product of step c) with cyanomethyl lithium; e) treating the product of step d) with oxalic acid; and f) treating the product of step e) with pyridinium tribromide in pyridine to yield dienogest.

  • Publication number: 20100092989
    Abstract: Described herein is a system for monitoring gene expression for diagnosing and monitoring inflammation disorders, and for monitoring gene expression in inflammation disorders in response to a particular drug treatment regimen. This system for detecting nucleic acid expression in a body fluid uses an isolated polynucleotide to detect expression of a nucleic acid comprising a nucleotide sequence selected from the group consisting of SEQ ID NO: 5; SEQ ID NO:11; SEQ ID NO:17; and SEQ ID NO: 23. These nucleic acids are differentially expressed in body fluid in an individual with a disease criterion for a disease as listed in Table 1 as compared to an individual without the disease criterion.

  • Publication number: 20050047647
    Abstract: The present invention relates to a system and method for attentional selection. More specifically, the present invention relates to a system and method for the automated selection and isolation of salient regions likely to contain objects, based on bottom-up visual attention, in order to allow unsupervised one-shot learning of multiple objects in cluttered images.

  • Publication number: 20020147548
    Abstract: Using data electrophoretic trace data from conventional nucleic acid sequencing equipment, a method for base calling that is tolerant to variable peak spacing is described. The method generates high-quality basecalls and reliable quality scores. In addition, a new type of quality score that estimates the probability of a deletion error between the current and the following basecall is described. A new protocol for benchmarking that better discerns basecaller performance is also provided.
