The negative-positive chromogenic process, despite being an important milestone in the evolution of color motion picture film technology, exhibits significant fading its image dyes, leading to loss chromatic integrity. A complete spectral approach for digital restoration is proposed. material-based processing method allows extract residual information associated with analytical densities, selec...

We prospectively assessed stool samples from 370 patients for Campylobacter species by comparing three selective agar media incubated at two temperatures: 42°C and 37°C. Twenty patients (5.4%) were found positive. The chromogenic medium CASA (AES Chemunex, France) proved highly efficient for C. jejuni and C. coli recovery, while lessening the workload in the lab.

We cloned a Streptomyces coelicolor A3(2) DNA fragment which directed synthesis of a brown pigment, presumably a shunt product in the actinorhodin biosynthetic pathway, on the plasmid vector pU41 in Streptomyces lividans. The pigment production was observed only when the DNA fragment was inserted downstream from a functional promoter sequence. By subcloning the fragment together with in vitro m...

Blood plasma contains a number of proteins capable of inhibiting the activation of plasminogen and the action of plasmin. Except for urokinase, the nature and action of plasminogen inhibitors are not yet fully understood. Inhibitors of plasmin, on the other hand, are fairly well defined and their clinical significance recognised. Although there are a number of plasmin inhibitors in plasma-for e...
