Abstract: An apparatus for measuring radiation at a region of interest inside a body is disclosed. The apparatus comprises a fiber optic equipped-catheter having a distal portion adapted to be inserted in a blood vessel. The apparatus further includes a luminescent scintillation material coupled to the fiber optic light pipe. The scintillation material is disposed in a distal portion of a lumen of the catheter and generates pulses of electromagnetic radiation in response to excitation by radiation rays. The apparatus further includes an index matching material disposed between the scintillation crystal and the fiber optic light pipe facilitating transmission of the pulses of electromagnetic radiation produced by the scintillation material to the fiber optic light pipe. A measuring assembly is coupled to the fiber optic light pipe to convert the pulses of radiation traversing the fiber optic light pipe to a measure of radiation in the region of interest. A method of measuring radiation using the radiation measuring apparatus of the present invention is also disclosed.      The steps of the method comprise: providing a catheter having a fiber optic light pipe coupled to a scintillation material supported by a distal portion of the catheter; inserting the distal portion of the catheter through an opening in the body; maneuvering the catheter to position the distal portion of the catheter within the region of interest; and converting the pulses of electromagnetic radiation transmitted along the fiber optic light pipe into a measure of radiation.

Granted: 2002-03-26
Abstract: A gyricon or twisting-particle display based on nonspheroidal (e.g., substantially cylindrical) optically anisotropic particles disposed in a substrate. The particles can be either bichromal or polychromal cylinders, preferably aligned parallel to one another and packed close together in a monolayer. A rotatable disposition of each particle is achievable while the particle is thus disposed in the substrate; for example, the particles can already be rotatable in the substrate, or can be rendered rotatable in the substrate by a nondestructive operation performed on the substrate. In particular, the substrate can be made up of an elastomer that is expanded by application of a fluid thereto so as to render the particles rotatable therein. A particle, when in its rotatable disposition, is not attached to the substrate. The close-packed monolayer configuration of particles provides excellent brightness characteristics and relative ease of manufacture as compared with certain other high-brightness gyricon displays. The substrate containing the cylinders can be fabricated with the swelled-elastomer techniques known from spherical-particle gyricon displays, with a simple agitation process step being used to align the cylinders within the sheeting material. Techniques for fabricating the cylinders are also disclosed.

Title: Disruption of expression of multiple alleles of mammalian genes
Inventor: LI LIMIN
IPC: C12N15/90
Filed: 1996-11-15
Granted: 2010-03-23
Abstract: Methods are provided for identifying a gene at a random chromosomal locus in the genome of a mammalian cell. The method involves inactivating one copy of the gene by integrating one DNA construct (knockout construct) in that gene copy. The knockout construct includes a positive selection marker region sequence and, in a 5' direction from the selection marker region sequence, a transcription initiation region sequence responsive to a transactivation factor, said transcription initiation region oriented for antisense RNA transcription in the direction away from the selection marker region sequence. The second copy of the gene is inactivated by transforming the cells with a second DNA construct (transactivation construct) containing a gene sequence for the transactivation factor which initiates antisense RNA transcription extending from the knockout construct into the chromosomal locus flanking the knockout construct at its 5' end. Inactivation of both gene copies may result in a change in cell phenotype distinguishable from the wild-type phenotype. Optionally, the wild-type phenotype can be regained by introducing a third construct that can inhibit antisense RNA transcription. A gene is provided associated with tumor susceptibility of mammalian cells, tsg 101.
