Utilizing a sensitive liquid chromatographic system, polyamines were quantitated in three-day plaque from 13 caries-resistant (CR) and 35 caries-susceptible (CS) adults after they had fasted for 12 hours. The values for putrescine and cadaverine were significantly higher in the CR group. This may be

K+ are selectively coordinated in the selectivity filter and concerted K+ and water movements in this region ensure high conduction rates in K+ channels. In channels with long pores many K+ binding sites are located intracellular to the selectivity filter (inner vestibule), but their contribution to

We studied the distribution of a polyamine oxidizing enzyme (PAO) in Onchocerca volvulus and other nematode parasites by immunohistochemistry and electron microscopy with immunogold technique using a polyclonal antiserum raised against purified PAO from Ascaris suum. In adult O. volvulus the protein
