摘要:
A system and method for manipulating and processing nanowires in solution with arrays of holographic optical traps. The system and method of the present invention is capable of creating hundreds of individually controlled optical traps with the ability to manipulate objects in three dimensions. Individual nanowires with cross-sections as small as 20 nm and lengths exceeding 20 µm are capable of being isolated, translated, rotated and deposited onto a substrate with holographic optical trap arrays under conditions where single traps have no discernible influence. Spatially localized photothermal and photochemical processes induced by the well-focused traps can also be used to melt localized domains on individual nanowires and to fuse nanowire junctions.
摘要:
Described herein are methods for analyzing polymer molecules. These methods are employed for the high throughput readout of DNA and RNA molecules with single molecule sensitivity. The method of the present invention comprises (1) the electrically controlled unzipping of DNA (or RNA) double strands, and (2) the readout of the molecule's identity (or code) using one or more molecule signal detection.
摘要:
A method of inhibiting growth rate, transformation or metastasis of mammalian cells, particularly epithelial cells, in which activity of at least one enzyme which participates in purine metabolism and regulations of nucleotide levels is elevated. In particular, a method of inhibiting transformation of mammalian cells by a DNA tumor virus, a DNA tumor virus factor or other factor which has an equivalent effect on cells.

摘要:
Molecular clones of feline leukemia virus isolates that encode (a) a prototype highly infectious, minimally pathogenic virus, (b) a variant genome that is replication-defective and associated with a fatal immunodeficiency in cats similar to AIDS (FAIDS) or (c) a chimeric genome that is replication-competent and induces FAIDS. These molecular clones may be used to generate cell lines producing infectious virus which is useful in the preparation of vaccines or in the generation of viremia or disease challenge systems.
摘要:
A system and method for providing improved de novo structure-based drug design that includes a method for more accurately predicting binding free energy. The system and method use a coarse-graing model with corresponding knowledge-based potential data to grow ligand candidates and libraries of ligand candidates. In light of the present inventions using coarse-graining model, the novel growth method of the present invention uses a Metropolis Monte Carlo selection process which result in a low energy structure that is not necessarily the lowest energy structure, yet results in a better ligand candidate.
摘要:
Procédé permettant d'inhiber le taux de croissance, la transformation ou métastase de cellules de mammifères, notamment de cellules épithéliales, où l'activité d'un enzyme au moins, participant dans les taux de métabolisme de la purine et de régulation des nucléotides, est élevée. On décrit en particulier un procédé permettant d'inhiber la transformation de cellules de mammifère par un virus oncogène de l'ADN, un facteur de virus oncogène de l'ADN, ou par d'autres facteurs ayant un effet semblable sur les cellules.
