Positron emission tomography (PET) imaging of tumor hypoxia provides valuable information for cancer treatment planning. Two types of PET tracers, nitroimidazole compounds and [62,64Cu] copper-diacetyl-bis[N(4)-methylthio- semicarbazone] (Cu-ATSM), have been used for imaging hypoxic tumors. High accumulation of these tracers in tumors was shown to predict poor prognosis. Both similar and differ...
Lactococcus lactis is a well-studied bacterium widely used in dairy fermentation and capable of producing metabolites with organoleptic and nutritional characteristics. For fine tuning of the distribution of glycolytic flux at the pyruvate branch from lactate to diacetyl and balancing the production of the two metabolites under aerobic conditions, a constitutive promoter library was constructed...
The title mol-ecule, C(23)H(15)N(3), is a terpyridine derivative resulting from the Friedländer annulation between 2,6-diacetyl-pyridine and N,N'-bis-(2-amino-benz-yl)ethyl-ene-di-amine. The asymmetric unit contains one half-mol-ecule, the complete mol-ecule being generated by a mirror plane (one N atom and one C atom lie on the plane). The mol-ecule, although aromatic, is deformed from planari...
was the case with the first design. Another advantage of the procedure described is that it enables the determination of total carbon and inorganic carbon in the range 10 to 50 mg/dm at a rate of 20 samples/h at a standard deviation of less than per cent. The described automated system is used very effectively in the authors laboratory for routine sample analysis. ACKNOWLEDGEMENTS This work wil...
