lysozyme is considered as part of the innate immune system. it has stimulated considerable interest as a natural food preservative. lysozyme has been shown to be effective in preserving a variety of foods such as fresh fruits and vegetables, meats, seafood and wine, for which many japanese patents have been granted. the relatively high thermal stability of lysozyme also makes it attractive for ...
The action of exogenous polyamines (putrescine, spermidine, and spermine) on ;washing' and fusicoccin-stimulated K(+) uptake and H(+) extrusion through the plasmamembrane in maize (Zea mays L., hybrid line Plenus S 516) root apical segments was studied. The results showed that polyamines inhibit the washing-stimulated K(+) influx and H(+) extrusion without interfering with K(+) uptake and H(+) ...
This study was conducted to assess the induced-changes in the content of total phenolics and individual phenolic acids, total and individual polyamines and some organic acids in the leaves of two important Iranian grapevine cultivars under different durations of drought stress, and to determine their involvement in grapevine drought tolerance. For this purpose, ‘Yaghuti’ as a drought-toler...
This article reports measurements of extracellular polyamines in rat brain. Microdialysis probes were implanted in the striatum and microperfusion samples were collected before, during, and after transient (20 min) global ischemia. Polyamine levels in microperfusates were measured by reverse-phase high-performance liquid chromatography after precolumn derivatization. No significant changes in e...
