The novel antitumor system including cluster rhenium compounds and cisplatin (Re-Pt 4:1 system) has been recently presented [Anticancer Research, 2007]. The structural types of dirhenium(III) carboxylates with formulas Re2(RCOO)4Cl2, Re2(RCOO)3Cl3, cis-Re2(RCOO)2Cl4, trans-Re2(RCOO)2Cl4, Re2(HPO4)4Cl2, phosphates and mixed carboxylates – phosphates were the matter of concern. The binuclear clus...

We have evaluated the potential of 188Re-labeled monoclonal antibodies (MAbs) modified with 2-iminothiolane (2IT) for targeting small-cell lung cancer (SCLC). Radiolabeled MAbs NK1NBL1 and C218 recognizing neural cell adhesion molecule were injected i.v. into athymic mice inoculated with human SCLC tumors, and the biodistribution was examined. NK1NBL1 localized in the tumors better than C218. 1...

the possibility of selective leaching process was investigated during molybdenite flue dust leaching to recover its rhenium content. the results show that addition of alcohols to water makes the medium less favorable for molybdenum transfer into aqueous phase. on the other hand, addition of small amounts of alcohols (5-15%) makes a noticeable separation of rhenium over molybdenum, but by increa...

Abstract The multi-orogenic crustal segment of the Central Western Carpathians comprises a Variscan basement that is host to small nickel–cobalt (Ni–Co) arsenide and sulfarsenide mineralizations at Ľubietová-Kolba Čierna Lehota (Slovakia). Here, we constrain timing Ni–Co mineralization by using rhenium-osmium (Re–Os) isotope geochemistry (1) gersdorffite (NiAsS) after krutovite (NiAs 2 ) Ľubiet...

Salt metathesis reactions between a low-valent rhenium(i) complex and series of amidinate-supported tetrylenes led to rhenium metallotetrylenes with varying extents Re–E multiple bonding.

The binding of carbon monoxide to iron, ruthenium, rhenium, and tungsten clusters is studied by means of infrared multiple photon dissociation spectroscopy. The CO stretching mode is used to probe the interaction of the CO molecule with the metal clusters and thereby the activation of the C-O bond. CO is found to adsorb molecularly to atop positions on iron clusters. On ruthenium and rhenium cl...

Hypertrophy and inflammation of the synovium with various underlying pathologies - such as rheumatoid arthritis, osteoarthritis, haemophilia and spondyloarthropathy - can be treated successfully by radiosynoviorthesis (RSO). For medium-sized joints (shoulder, elbow, wrist, hip and ankle), the radionuclide of choice is rhenium-186. We review the evidence for the efficacy of this local, relativel...
