Media = linia mediana = partnership co-operation profile The paper proposes a Performance Analysis Model (PAM) as base for analysis of goal driven measurements within software development process. The model is developed on common view of the process for bot...

Cu50Zr45Al₅ bulk metallic glass (BMG) presents high fracture strength. For improving its plasticity and controlling its mechanical properties, superficial dealloying of the BMG was performed. A composite structure containing an inner rod-shaped Cu-Zr-Al amorphous core with high strength and an outer dealloyed nanoporous layer with high energy absorption capacity was obtained. The microstructure...

In the title compound, hexa-μ(2)-bromido-μ(4)-oxo-tetra-kis{[3-(1-methyl-2-pyrrolidin-yl)pyridine-κN]copper(II)}, [Cu(4)Br(6)O(C(10)H(14)N(2))(4)], the four Cu atoms are tetra-hedrally arranged around the O atom at the cluster center. The Cu and coordinated N atoms lie along directions which correspond to four of the eight threefold axial directions of a regular octa-hedron. Each Cu atom lies a...

Serum copper and zinc concentrations and 24 hour urinary copper and zinc excretion were determined serially from the beginning of treatment with D-penicillamine in four children with Wilson's disease. The data show a progressive decrease in both serum copper and zinc concentrations in all. Urinary copper excretion gradually levelled off to approximately 50% of initial values, but zinc excretion...

Ceruloplasmin is a multicopper oxidase essential for normal iron homeostasis. To elucidate the mechanisms of copper incorporation into this protein, holoceruloplasmin biosynthesis was examined by immunoblot analysis and (64)Cu metabolic labeling of Chinese hamster ovary cells transfected with cDNAs encoding wild-type or mutant ceruloplasmin. This analysis reveals that the incorporation of coppe...

Copper-64 is a useful radioisotope for positron emission tomography (PET). Due to the wide range of applications, the demand of 64Cu with low metallic impurities is increasing. Here we report a simple method for the efficient production of high specific activity 64Cu using a cyclotron for biomedical application. We designed new equipment based on the plating of enriched 64Ni as the target, and ...

Several components of branchial copper uptake were identified in juvenile freshwater rainbow trout (Oncorhynchus mykiss) using (64)Cu. On the basis of competitive interactions between sodium and copper uptake, inhibition of copper uptake by a proton pump inhibitor (bafilomycin A1, 2 micromol l(-1)) and a Na(+) channel blocker (phenamil, 100 micromol l(-1)), it appears that a proportion of the b...

BACKGROUND Hypoxia and increased glycolytic activity of tumors are associated with poor prognosis. The purpose of this study was to investigate differences in radiotherapy (RT) dose painting based on the uptake of 2-deoxy-2-[(18) F]-fluorodeoxyglucose (FDG) and the proposed hypoxia tracer, copper(II)diacetyl-bis(N(4))-methylsemithiocarbazone (Cu-ATSM) using spontaneous clinical canine tumor mod...

Copper-64 shows promise as both a suitable PET imaging and therapeutic radionuclide due to its nuclear characteristics. Stable attachment of radioactive (64)Cu(2+) to targeted imaging probes requires the use of a bifunctional chelator. Sarcophagine (Sar) ligands coordinate the metal ion (64)Cu(2+) within the multiple macrocyclic rings comprising the cage structure, yielding extraordinarily stab...

Glioblastoma multiforme (GBM) is the most common primary malignant brain tumor in adults with a median survival time less than one year. To date, there are only a limited number of effective agents available for GBM therapy and this does not seem to add much survival advantage over the conventional approach based on surgery and radiotherapy. Therefore, the development of novel therapeutic appro...
