摘要:
The present disclosure discusses a system and method for continuous operation of an ion trap mass spectrometer. The described system does not introduce ions into the ion trap in distinct trapping phase, rather the described system continuously injects ions into the ion trap while continuously scanning out the ions. The system and method described herein achieves a much higher duty cycle and cycle rate when compared to standard mass spectrometer devices.

摘要:
A delivery device that allows for the sustained release of an agent, particularly useful for the sustained release of a therapeutic agent to limited access regions, such as the posterior chamber of the eye and inner ear. The delivery device is minimally invasive, refillable and may be easily fixed to the treatment area. The delivery device includes a hollow body with an inlet port at its proximal end for insertion of the agent, a reservoir for holding the agent and a delivery mechanism for the sustained delivery of the agent from the reservoir to the patient.
摘要:
The present invention sterol-modified hedgehog polypeptides and functional fragments thereof Methods of identifying compositions which affect hedgehog activity based on inhibition of cholesterol modification of hedgehog protein are described. In one aspect of the invention, the method provides a means for affecting cholesterol biosynthesis or transport in a cell comprising contacting a cell with an effective amount of a compound that affects hedgehog, thereby affecting cholesterol biosynthesis or transport. The effect may be inhibition or stimulation of cholesterol biosynthesis or transport.
摘要:
A transgenic non-human animal of the species selected from the group consisting of avian, bovine, ovine and porcine having a transgene which results in disrupting the production of and/or activity of growth differentiation factor-8 (GDF-8) chromosomally integrated into the germ cells of the animal is disclosed. Also disclosed are methods for making such animals, and methods of treating animals, including humans, with antibodies or antisense directed to GDF-8. The animals so treated are characterized by increased muscle tissue and bone content.
摘要:
Methods for detection of a cell proliferative disorder, such as cancer, are provided utilizing analysis of target mutant nucleic acids in saliva specimens are described. The presence of target mutant nucleic acids is indicative of a neoplastic disorder of the lung or the head and neck.
摘要:
The invention is specifically directed to efficient, random, simple insertion of a transposon or derivative transposable element into DNA in vivo or in vitro. The invention is particularly directed to mutations in ATP-utilizing regulatory transposition proteins that permit insertion with less target-site specificity than wild-type. The invention encompasses gain-of-function mutations in TnsC, an ATP-utilizing regulatory transposition protein that activates the bacterial transposon Tn7. Such mutations enable the insertion of a Tn7 transposon or derivative transposable element in a non-specific manner into a given DNA segment. Insertion can be effected in plasmid and cosmid libraries, cDNA libraries, PCR products, bacterial artificial chromosomes, yeast artificial chromosomes, mammalian artificial chromosomes, genomic DNAs, and the like. Such insertion is useful in DNA sequencing methods, for genetic analysis by insertional mutagenesis, and alteration of gene expression by insertion of a given genetic sequence.
摘要:
Monoclonal antibodies and method for ameliorating an immune response disorder. The monoclonal antibodies are specific for an epitope present on the leukocyte adhesion receptor null-chain.
摘要:
Methods, apparatuses, and systems for monitoring health of corneal tissue are disclosed. The system includes a corneal measurement device configured to measure a first state of health indicator that is tissue thickness or volume of a region of the corneal tissue during a first period of time and a second state of health indicator that is tissue thickness or volume of the region during a second period of time after the first period of time. The system further includes a processing unit configured to receive the first and second state of health indicators from the corneal measurement device and generate a health map of the region based on the first and second state of health indicators, the health map indicative of a change between the first and second state of health indicators as measured from the first period of time to the second period of time in the region of the cornea.
