摘要:
Methods and compositions for producing a labeled population of nucleic acids for use in an array-based comparative genome hybridization (CGH) assay are provided. In general, the methods involve cleaving a genomic source to produce a sample containing nucleic acid fragments, and end-labeling the nucleic acid fragments to provide a population of nucleic acids having a terminal label. Kits and systems for use in practicing the subject methods are also provided.

A flow control device includes a sealing component that can be positioned within a bronchial lumen. The sealing component can comprise two or more overlapping segments that are movable relative to one another such that the segments collectively form a seal that can expand and contract in size to fit within and seal bronchial lumens of various sizes.

Devices, systems, and methods for suturing of body lumens allow the suturing of vascular puncture sites located at the distal end of a percutaneous tissue tract. An elongated articulated foot near a distal end of a shaft is inserted through the penetration and actuated so that the foot extends along the lumenal axis. The foot carries suturing attachment cuffs, and needles are advanced from the shaft through the vessel wall outside of the penetration and into engagement with the needle cuffs after the foot has been drawn proximally up against the endothelial surface of the blood vessel. The cross-section of the shaft within the tissue tract can be minimized by laterally deflecting the needles as they leave the shaft, while tapered depressions within the foot can guide the advancing needles into engagement with the cuffs. The cuffs lockingly engage the needles and can be withdrawn proximally along the needle paths and through the tissue tract so as to form a loop of suture across the puncture. The articulating foot may be realigned with the shaft and withdrawn proximally through the tissue tract without dilating the tissue tract.
摘要:
Disclosed are methods and devices for regulating fluid flow to and from a region of a patient's lung, such as to achieve a desired fluid flow dynamic to a lung region during respiration and/or to induce collapse in one or more lung regions. Pursuant to an exemplary procedure, an identified region of the lung is targeted for treatment. The targeted lung region is then bronchially isolated to regulate airflow into and/or out of the targeted lung region through one or more bronchial passageways that feed air to the targeted lung region.
摘要:
A system for communicating information, particular for use in a hydrocarbon well, is described including one or more releasable vessels having radio frequency (RF) circuitry responsive, when in use, to an RF reader system, the vessel including counteracting means to reduce the effect of destabilizing flow forces thereby extending the coupling time with the reader system.
摘要:
Methods and compositions for assessing CpG island methylation are provided. Specifically, the invention provides an unstructured nucleic acid (UNA) oligonucleotide that base pairs with, i.e., hybridizes to, CpG islands. The subject oligonucleotide may be present in an array, and find use in methods for evaluating methylation of CpG islands in cells. Kits and computer programming for use in practicing the subject methods are also provided.
摘要:
Methods and compositions for assessing chromosome copy number are provided. Specifically, the invention provides an array containing a plurality of features including at least one feature that contains oligonucleotides that are complementary to a structural region of a chromosome. The subject methods and compositions may be used to detect chromosome copy number in a cell, and, as such, may be employed in a variety of diagnostic and research applications. Kits and computer programming for use in practicing the subject methods are also provided.
摘要:
A turbine blade including an airfoil having a profile in accordance with Table 1 is disclosed. The turbine blade has a plurality of cooling passages extending radially outward through the airfoil. The aerodynamic profile of the airfoil has been reconfigured to reduce airfoil stress for a given operating temperature, thereby resulting in increased creep rupture life of the airfoil.
摘要:
Methods and systems for lung volume reduction of a patient are described. The methods include implanting a flow control device in a bronchial passageway of the lung. The flow control device regulates fluid flow through the bronchial passageway and includes a valve protector that at least partially surrounds a valve member. The valve protector has sufficient rigidity to maintain the shape of the valve member against compression.
摘要:
Patient specific array-based assays are provided. A feature of the subject patient specific array-based assays is that they include a step of interrogating a set of array features that have been previously identified by a general array-based assay to be relevant to a specific disease and condition of the subject being assayed. Also provided are methods of producing the subject patient specific array-based assays, as well as compositions and kits for use in practicing the subject assays.
