Surprisingly the overall recurrence and survival rates of brachytherapy do not compare with external beam radiotherapy (Voges et al 1997). This WebElements periodic table page contains the essentials for the element rhenium. 6 - Relative Atommasse des Rhenium-Isotops (Isotopenmasse inklusive Elektronen) und in eckigen Klammern die Masse des Atomkerns (Kernmasse, Nuklidmasse ohne Elektronen), jeweils bezogen auf 12C = 12,00000 [2].
Geology 40:199–202, Rudnick RL, Gao S (2003) Composition of the continental crust. Moreover, Szeifert et al. Natural rhenium is a mixture of two stable isotopes. Journal of the Geological Society, London, Vol. The Boiling point is 5590°C, 10094°F, and 5863 K. 187 Re is the Rhenium’s Key Isotope known.
Durch isomorphen Einbau kann Re im Molybdändisulfid bis auf 0,2 % angereichert sein. In addition, 186Re preparations are reported to be less viscous, and potentially could extravasate beyond the cyst wall.
In this scenario, streptavidin is conjugated to an antitumor IgG and the resultant bioconjugate is administered. [5] - Pekka Pyykkö: Year-2008 nuclear quadrupole moments. Science 243, 519–522. Die Rhemium-reichsten Lagerstätten (Kupfererz mit Molybdän-Gehalten) befinden sich entlang des westlichen Küstenstreifens des amerikanischen Kontinents; sie bilden ca. Both Rhenium isotopes are used for medical purposes. ( ) spin value – Indicates spin with weak assignment arguments.
Metallisches Re sowie seine Salze und Oxide finden außerdem als besonders selektive vergiftungsbeständige Katalysatoren bei der Hydrierung und Dehydrierung sowie in der Alken-Metathese[5] Anwendung.

Theoretically, they are said to facilitate delivery of higher radiation doses to the cyst lining than can be achieved by external beam radiotherapy, damaging the secretory epithelial lining, leading to elimination of fluid production and eventually cyst involution. published their results of radionuclide synoviorthesis using either yttrium-90 or rhenium-186 in a large cohort of 500 subjects over a 38-year period. 1, S. 201, 222, 236; Bd. Mar Chem 25:163–181, Carlson RW (2005) Application of the Pt–Re–Os isotopic systems to mantle geochemistry and geochronology. Das Verhältnis 187Re/187Os bzw. This is not only problem for therapy but for diagnosis as well, because even though the target uptake is sufficient, it is the high background that results in poor image contrast and target detection [241]. 7 - Kernspin I, Einheit: h/2π. Among elements with a known stable isotope, only indium and tellurium similarly occur with a stable isotope in lower abundance than the long-lived radioactive isotope. II.
While both 32P and 90Y are pure beta (β) particle-emitting isotopes that are made in colloidal suspensions, 186Re has both β and γ emission. 5 - Bezeichnung des Rhenium-Isotops; gegebenenfalls Trivialnamen.
During two-step pretargeting, bispecific antibody (bsmAb) is first administered and given time for the target localization and clearance from blood and healthy tissue, then a radiolabeled hapten molecule with high affinity to the bispecific antibody as well as fast pharmacokinetic and clearance properties is administered (Figure 17.8). Third-row transition element. De naam renium is afgeleid van de Latijnse naam voor de rivier de Rijn: Rhenus. Die mit heutigen Mitteln gewinnbaren Vorräte an Re liegen bei 100000 t. Beim Röstprozeß setzt sich das in den Erzen befindliche Re zu Rheniumheptoxid (Re2O7) um.
