Patent number: 6704662Abstract: A technique is described for quantitating biological indicators, such as viral load, using interferometric interactions such as quantum resonance interferometry. A biological sample is applied to an array information structure that has a plurality of elements that emit data indicative of viral load. A digitized output pattern of the arrayed information structure is interferometrically enhanced by generating interference between the output pattern and a reference wave. The interferometrically enhanced output pattern is then analyzed to identify emitted data indicative of viral load which in turn is used to determine viral load.Type: GrantFiled: July 2, 2002Date of Patent: March 9, 2004Assignee: ViaLogy Corp.Inventor: Sandeep Gulati

Patent number: 6678618Abstract: A new method to analyze and predict the binding energy for enzyme-transition state inhibitor interactions is presented. Computational neural networks are employed to discovery quantum mechanical features of transition states and putative inhibitors necessary for binding. The method is able to generate its own relationship between the quantum mechanical structure of the inhibitor and the strength of binding. Feed-forward neural networks with back propagation of error can be trained to recognize the quantum mechanical electrostatic potential at the entire van der Waals surface, rather than a collapsed representation, of a group of training inhibitors and to predict the strength of interactions between the enzyme and a group of novel inhibitors. The experimental results show that the neural networks can predict with quantitative accuracy the binding strength of new inhibitors.Type: GrantFiled: November 13, 2000Date of Patent: January 13, 2004Assignee: Albert Einstein College of Medicine of Yeshiva UniversityInventors: Steven D.

Patent number: 6673577Abstract: The present invention discloses a methodology which is directed to providing positive confirmation that nucleic acids, possessing putatively identified sequences predicted to generate observed GeneCalling™ signals, are actually present within the sample from which the signal was originally derived. The putatively identified nucleic acid fragment within the sample possesses 3′- and 5′-ends with known terminal subsequences. The method involves contacting nucleic acid fragments in a sample in amplifying conditions with (i) a nucleic acid polymerase; (ii) “regular” primer oligonucleotides having sequences comprising hybridizable portions of known terminal subsequences; and (iii) a “poisoning” oligonucleotide primer. Nucleic acids amplified with a poisoning primer are distinguishable upon detection from nucleic acids amplified with regular primers.Type: GrantFiled: November 14, 2000Date of Patent: January 6, 2004Assignee: CuraGen CorporationInventors: Jonathan M.
