Abstract:
Downhole tool assemblies having mule shoe members housed within UBHO sub members being secured by fastening members and methods thereof are disclosed. A lower portion of the mule shoe member has many apertures disposed circumferentially around an external surface that are aligned with openings present in the UBHO sub member to achieve a specified orientation. Fastening members releasably engage and couple the apertures with the openings thereby securely locking the mule shoe member within the UBHO sub member in the specified orientation. Set screws having an elongated dowel member protruding from a centre of a face at a bottom end are disclosed. The dowel member is coaxial with the body of the screw having a lesser width and is configured for being substantially seated within a receiving member for providing a positive lock.
Abstract:
Compositions and methods effective in inhibiting abnormal or undesirable cell proliferation, particularly endothelial cell proliferation and angiogenesis related to neovascularization and tumor growth are provided. The compositions comprise peptide molecules, optionally containing one or more individual peptide chains covalently linked, and optionally modified with polyethylene glycol (PEG). The methods involve administering to a human or animal the composition described herein in a dosage sufficient to inhibit cell proliferation, particularly endothelial cell proliferation. The methods are useful for treating diseases and processes mediated by undesired and uncontrolled cell proliferation, such as cancer, particularly by inhibiting angiogenesis. Administration of the composition to a human or animal having prevascularized, metastasized tumors is useful for preventing the growth or expansion of such tumors.
Abstract:
A system and method enable automatic importation of data from an external data source into an electronic workspace in the form of a visual hierarchy. To display data from a data source, data is retrieved from the external data source, and a visual presentation format for the data is created based on characteristics of the data (e.g., the field to which the data is assigned in the data source, the type of data, the value of the data, etc), where the visual presentation format is hierarchical. The data is then displayed in an electronic workspace in the form of visual hierarchy that is accordance with such visual presentation format. In the electronic workspace, a user can manipulate and supplement the data without affecting the data source, unless there is a trigger event that causes modifications to the data to be written back to the data source. A further embodiment of the present invention enables modifications to the data in the workspace to be written back to the data source upon the occurrence of one or more select events. When such an event occurs, rules, which are essentially the inverse of the rules applied to create the visual presentation format, are used to convert the visual presentation format back to the data source format. The modified data is then written back to the data source.

Abstract:
The present invention relates to a peptide-based compound comprising a peptide moiety and a poly(ethylene glycol) moiety wherein the poly(ethylene glycol) moiety (preferably linear) has a molecular weight of more than 20 KDaltons (preferably from 20 to 60 KDaltons). The peptide moiety may be monomeric, dimeric or oligomeric. Such peptide-based compounds may optional include a linker moiety and/or a spacer moiety.
Abstract:
The present invention relates to a compound comprising a peptide moiety, a spacer moiety and a water-soluble polymer moiety such as a poly(ethylene glycol) moiety. The spacer moiety is between the peptide moiety and the water-soluble polymer moiety. The spacer moiety has the structure: —NH—(CH2)α—[O—(CH2)β]γ—Oδ—(CH2)ε—Y—wherein α, β, γ, δ, and ε are each integers whose values are independently selected.
Abstract:
The present invention relates to peptide compounds that are agonists of the erythropoietin receptor (EPO-R). The invention also relates to therapeutic methods using such peptide compounds to treat disorders associated with insufficient or defective red blood cell production. Pharmaceutical compositions, which comprise the peptide compounds of the invention, are also provided.
Abstract:
A synthetic strategy for the creation of large scale chemical diversity. Solid-phase chemistry, photolabile protecting groups, and photolithography are used to achieve light-directed spatially-addressable parallel chemical synthesis. Binary masking techniques are utilized in one embodiment. A reactor system, photoremovable protective groups, and improved data collection and handling techniques are also disclosed. A technique for screening linker molecules is also provided.
