摘要:
The present invention relates to the use of nanoscintillation systems, or nanoparticles containing fluor molecules, that can be used to detect an electron-emitting or alpha-particle-emitting radioisotope in the absence of organic-solvents commonly used in organic-based liquid scintillation cocktails. The invention also relates to compositions and use of three oil-in-water microemulsion precursors that can be engineered rapidly, reproducibly, and cost-effectively to produce useful nanoparticles less than 100 nanometers.
摘要:
A method of treating leukemia which includes administering an effective amount of composition comprising suramin and a biological response modifier, wherein the suramin and the biological response modifier show synergistic or additive anti-leukemic activity. A pharmaceutical composition is also disclosed.
摘要:
A shunt includes a tubular body having first and second legs at a proximal end and a third leg at a distal end. A fluid distensible balloon and cooperating insufflation conduit are carried on the tubular body. The first leg of the tubular body includes a longitudinal slit for receiving the second leg whereby the first and second legs may be positioned substantially coaxial so as to allow easier introduction of the shunt into the blood vessel of a patient. Similarly, the second leg having a longitudinally slit for receiving a portion of the cooperating insufflation conduit and also holding it in a coaxial position. A leader tube with a blunt atraumatic tip is received over the proximal end of the tubular body to further aid in the introduction of the shunt.
摘要:
A computer implemented method for achieving optimum selection of machining parameters and tool inserts for finish turning operations is provided. The computer implemented method allows for the simultaneous consideration of the various machining performance criteria which are highly interactive and need to be taken into consideration when defining optimum cutting conditions or selecting optimum tool inserts for particular cutting conditions. The computer implemented method broadly includes the steps of (1) developing a process model for interrelating performance variables and process parameters for finish turning operations; (2) selecting one of the performance variables for optimization while maintaining the remaining performance variables and process parameters as constraints on the optimization process; and (3) applying non-linear programming techniques to the process model in order that optimum cutting conditions may be determined for a given tool insert or an optimum tool insert may be selected for given machining performance requirements.
摘要:
Optically active nornicotine compounds as a treatment for dopamine-related conditions and disease states. Such disease states include the treatment of myasthenia gravis, Parkinson's disease, Alzheimer's disease, schizophrenia, eating disorders, ulcers, drug addiction and as a substitute for psycho-stimulant self-administration.
摘要:
A method for preparing biodegradable microspheres having a three-dimensional network in which biologically active macromolecular agents are physically entrapped therein. The microsphere is able to degrade and release the macromolecular agent at a controlled rate. The method involves emulsifying a vinyl derivative of a biodegradable hydrophilic polymer, a water-soluble monovinyl monomer and a biologically active macromolecule in water, and copolymerizing the biodegradable hydrophilic polymer and the water-soluble monovinyl monomer such that the biologically active macromolecule is entrapped therein.
摘要:
Controlled release drug delivery systems comprised of spherical microporous polymeric network of interconnecting channels containing pore incorporated drugs or other agents wherein the drugs or agents are confined within the pore channel are described. Also disclosed are processing parameters in connection with the novel method of the invention for obtaining drug delivery systems especially suited for parenteral as well as oral administration.
摘要:
Anticonvulsant compositions comprise as the active ingredient a compound selected from the group consisting of those of the formulae: ##STR1## wherein R.sub.1 is o-chlorophenyl, o-nitrophenyl, 2,4- or 2,6-dichlorophenyl, 4-pyridyl, 3-pyridyl, 2-pyridyl, or 2-quinolyl, and R.sub.2 is hydrogen, m- or p-trifluoromethyl, m-chloro-p-fluoro, p-methyl, p-ethyl, m- or p-chloro, m-nitro, p-bromo, p-fluoro, or p-COOR.sub.3, wherein R.sub.3 is lower alkyl of 1 to 4 carbon atoms. The compositions are administered to mammals in an amount to provide a dosage amount ranging from about 30 mg/kg to 300 mg/kg.
