Abstract:
본 발명은 광학영상 조영제, 그 용도 및 장치에 관한 것이다. 본 발명의 광학영상 조영제는 발광을 위하여 별도의 형광물질 또는 발광물질 을 포함할 필요가 없어 원래 분자의 물리화학적 성질을 변화시키지 않고도 광학영 상을 획득할 수 있다. 본 발명의 광학영상 조영제는 많은 경우 광학/핵의학 이중영 상 조영제로 사용될 수 있으며, 방사성치료와 동시에 치료효과를 광학영상으로 모 니터링할 수 있는 장점을 가지고 있다. 또한, 형광물질과 결합되는 경우 외부에서 에너지가 유입되지 않고서도 광학영상 조영제에서 발생하는 에너지를 통해 자체적 으로 형광물질에서 빛이 방출되어 광량을 증가시키고 조직 투과력을 향상시킬 수 있다.
Abstract:
The present invention relates to biochemical methods for assessing metabolic fitness and/or aerobic demands of a living system. Specifically, the rate of synthesis and turnover of the molecular components of mitochondrial mass are used to determine the aerobic capacity and/or aerobic demand of tissues or living organisms. The direct measurement of metabolic fitness and/or aerobic demand by this means can be used as an index of the efficacy of an exercise training program or other therapeutic intervention; as a medical risk factor for predicting the risk of cardiovascular disease, diabetes, death or other health outcome; or as an aid to pharmaceutical companies for drug discovery in the area of metabolic fitness, deconditioning, and oxidative biology.
Abstract:
Protocols for radioimaging an event or disorder are provided. An exemplary protocol comprises a method of radioimaging a myocardial perfusion, the method comprising in sequence: (a) administering to a subject about 3 mCi Tl201 thallous chloride; (b) allowing said subject to rest; (c) radioimaging a heart of said subject; (d) subjecting said subject to a physical stress; (e) administering to said subject at a peak of said physical stress about 20-30 mCi Tc99m sestamibi; and (f) radioimaging said heart of said subject, thereby radioimaging a myocardial perfusion.
Abstract:
Systems and methods are described for efficiently producing a radiopharmaceutical agent. The system includes a generator that provides an admixture comprising hydrochloric acid and gallium-68 (Ga-68). A heater initiates a removal process by evaporating the hydrochloric acid from the admixture resulting in a substantially purified Ga-68. A plurality of valves provides a buffer and a prodrug that gets mixed with the Ga-68 to produce Ga-68 radiopharmaceutical agent.. Additionally, the valves may provide water or a transchelator to the Ga-68 radiopharmaceutical agent to optimize the yield. A method includes providing an admixture comprising hydrochloric acid and Ga-68. The method also includes removing the hydrochloric acid by heating the admixture and subsequently evaporating the hydrochloric acid, resulting in a substantially purified Ga-68. The method further includes adding a buffer and a prodrug to the substantially purified Ga-68 to produce the Ga-68 radiopharmaceutical agent.
Abstract:
The present invention relates to a combination of a pharmaceutical composition comprising a gallium compound, especially gallium nitrate, and one or more nonchemotherapeutic anticancer agents (NCAA) including antibodies, antisense molecules, anti-telomerase agents, aptamers, biologic response modifiers, bisphosphonates, cytotoxic fusion proteins, immunomodulatory agents, immunostimulatory agents, molecular decoys, molecular inhibitors, proteasome inhibitors, protein kinase inhibitors, retinoids, transcription factors and arsenic compounds, for the treatment of neoplasic disease in a mammal in need of treatment thereof.
Abstract:
The present invention provides a photoreactive reagent that binds specifically to Ca 2+ -binding proteins, links to them covalently after photo-activation, and labels them. The novel reagent enables the characterization, purification, inhibition and screening of Ca 2+ -binding proteins, as well as the preparation of a new affinity chromatography matrix and a new protein biosensor. The invention also relates to the use of the reagent in inhibiting apoptosis and necrosis and in diagnosing a disorder associated with a defect in the function of a Ca 2+ -binding protein, and in the preparation of a medicament for treating such disorders.
Abstract:
One aspect of the present invention relates to a microsphere impregnated with a radioisotope that emits therapeutic ß-particles and a radioisotope that emits diagnostic γ-radiation; wherein the atomic number of the first radioisotope is not the same as the atomic number of the second radioisotope. In one preferred embodiment, the microsphere is composed of glass impregnated with 90 Y as the source of the therapeutic ß-emissions and 198 Au as the source of the diagnostic γ-emissions. Another aspect of the present invention relates to the preparation of a microsphere impregnated with a radioisotope that emits therapeutic ß-particles and a radioisotope that emits diagnostic γ-radiation; wherein the atomic number of the first radioisotope is not the same as the atomic number of the second radioisotope. In one preferred embodiment, a glass microsphere containing 90 Y and 198 Au is prepared by neutron activation of a glass microsphere comprising glass, 89 Y and 197 Au. Another aspect of the present invention relates to administration to a mammal of a therapeutically effective amount of microspheres impregnated with a ß-emitting radioisotope and a γ-emitting radioisotope; wherein the atomic number of the first radioisotope is not the same as the atomic number of the second radioisotope. In one preferred embodiment, said microspheres are administered to the patient through a catheter.
Abstract:
A method for producing Ac-225 is presented, wherein Ac-225 is produced by bombardment of Ra-226 with deuterons accelerated in a cyclotron. The deuterons preferably have an incident energy of between 15 and 22 MeV. The method, which allows production of Ac-225 at high yields and purity levels, is particularly interesting in view of Bi-213 generation.
