BACKGROUND Earwax is a common problem in general practice. The incidence of complaints owing to earwax in general practice in the Netherlands is 39.3 per 1000 patients. AIM To determine the feasibility of a strategy using water as a quick dispersant for persistent earwax, compared with the usual strategy using oil as a dispersant for three days in a general practice setting. DESIGN OF STUDY...

The uptake of anionic amino acids by the rat hepatoma cell line, HTC, occurs by two saturable routes, one Na+-dependent and one Na+-independent. Which of the two mediations will serve for transport of a given anionic amino acid depends on the chain length of that anionic substrate. The Na+-independent system, shared by glutamate, cystine, and anionic amino acids intermediate in length between t...

Polycationic ferritin, a multivalent ligand, was used as a visual probe to determine the distribution and density of anionic sites on the surfaces of rat liver mitochondrial membranes. Both the distribution of bound polycationic ferritin and the topography of the outer surface of the inner mitochondrial membrane were studied in depth by utilizing thin sections and critical-point dried, whole mo...

various kinds of chemicals are used in papermaking to enhance paper properties and to improve efficiency of the production process. in the presence of cationic starch as an anionic charge catcher, effects of nano silica/cationic polyacrylamide complex on retention, drainage time, water volume drained by dynamic drainage jar and properties of paper recycled from old corrugated container were inv...

The reversal of the inhibitory action of antiseptics by substances showing a specific affinity for the inhibiting agent has been reported for many compounds, the most striking effect probably being the reversal of the action of mercurials by H2S, glutathione, sodium thioglycolate, etc. Valko and DuBois (1944) have reported that the germicidal action of cationic detergents against both gram-posi...
