R esum e Nous avons d evelopp e un nouvel algorithme de GC temps r eel \dur". Notre algorithme place une limite sup erieure sur le temps d'ex ecution de chaque primitive d'allocation ou d'acc es aux objets, selon leur nature. Il s'agit d'un GC compactant. Nous l'avons implant e et avons v erii e qu'une application a allocation intensive tourne seulement environ 3 fois plus lentement avec ce GC ...

introduction: the purpose of this study was to cultivate bone marrow cells from two different mouse strains (nmri and balb/c) and to examine them in terms of expression of ten surface antigens from primary culture to passage 3. material and methods: 6-8 weeks old either nmri or balb/c mice were sacrificed and their bone marrows were harvested and cultivated .two weeks after culture initiation, ...

A novel compound, KS-505a was isolated from the culture broth of a strain identified as Streptomyces argenteolus A-2. The compound inhibited bovine brain Ca2+ and calmodulin-dependent cyclic-nucleotide phosphodiesterase with an IC50 value (the concentration causing 50% inhibition) of 0.065 microM. The compound around that concentration had little or no effect on heart calmodulin-dependent and -...

Carbon-labeled glycolaldehyde prepared from [(14)C]serine was used to supply the nutritional requirement of a pyridoxineless auxotroph of Escherichia coli. Pyridoxal phosphate isolated from bacteria so grown was found to have incorporated the radioactive glycolaldehyde with little dilution. The radioactivity which was unincorporated into pyridoxal phosphate was recovered almost entirely in the ...

Due to the obligatory intracellular lifestyle of viruses, cell culture systems for efficient viral propagation are crucial to obtain a detailed understanding of the virus-host cell interaction. For hepatitis C virus (HCV) the development of permissive and authentic culture models continues to be a challenging task. The first efforts to culture HCV had limited success and range back to before th...

Computer-mediated communication between humans is becoming ubiquitous. Computers are increasingly connected via high-speed local and widearea networks, and via wireless technologies. High bandwidth interaction is increasing communication speed, offering the possibility for transmission of images, voice, sound, video and formatted data as well as text. Computer technologies are creating the poss...

herein, we presented the first report on bluetongue (bt) disease in 10 pregnant camels in a herd fromkerman province, iran. all sera samples were tested serologically (agid, c-elisa). we also used the razi-bk cell line, performed primary culture of ovine kidney and inoculated intravenously the embryonatedchicken eggs (ece) to culture and isolate the bt virus. efforts to culture and isolation of...
