introduction: in this study we examined the effect of different concentration of cycloheximide on the enhancement of vero cell sensitivity to vero cytotoxin (vt) of escherichia coli. materials and method: cycloheximide at different concentrations (0.5-16mg/ml) were added to vero cells, for different peroids of time: 1 day before, immediately after, or 1 and 2 days after the adddition of vt. res...

Cycloheximide accumulation in a fermentation medium has been shown to be the product of the balance between synthesis and degradation of this antibiotic. Glucose has been shown to prevent cycloheximide degradation. Cycloheximide has been shown to interfere with its own synthesis probably due to feedback inhibition. Approaches for increasing cycloheximide titers in the light of these findings ar...

Abstract Background Long-term memory formation is generally assumed to involve the permanent storage of recently acquired memories, making them relatively insensitive disruption, a process referred as consolidation. However, when retrieved under specific circumstances, consolidated fear memories are thought return labile state, thereby opening window for modification (e.g., attenuation) memory....

In this study the programmed cell death (apoptosis) of human neutrophilic granulocytes was investigated in the presence and absence of fetal calf serum (FCS), cycloheximide and actinomycin-D. The results show that when FCS is omitted from cultures, apart from a decrease in viability, the percentage of apoptotic cells and DNA fragmentation increases. Apoptosis is accelerated in serum withdra...
