The present application relates to compositions comprising 4-chloroindole-3-acetic acid (4CI-AA) or an analogue thereof, or a combination of the latter, in acid, salt or ester form. For example, such compositions can be used to curb weeds.

The present invention concerns a new antimicrobial denture adhesive composition useful to be used for fixing dentures, which includes copper nanoparticles (CuNPs) that provides antimicrobial properties against dental pathogens such as Candida albicans, Streptococcus mutans, Staphylococcus aureus and Aggregatibacter actinomycetemcomitans. Surprisingly, the composition for a denture adhesive comprising copper nanoparticles (CuNPs) not only shown excellent antimicrobial properties, but also improved adhesive properties in comparison with other denture adhesives existing currently in the marked, which do not contain said CuNPs.

A topical serum and its method of production and use. The serum is used to treat damage on plant tissue, such as damaged leaves. The serum triggers the immunity responses of the plant, therein enabling the damaged tissue to heal, rather than die and fall away from the plant. The serum is a combination of aqueous solutions. The first solution contains at least one immunity response compound that is selected from methyl jasmonate and methyl salicylate. The second solution contains at least one B vitamin. The solutions are mixed to form a topical serum. The topical serum is applied over the damaged tissue, wherein the immunity response compounds enhance the pattern-triggered immunity response and the effector-triggered immunity response of the plant. The vitamin B solution inhibits the oxidation and preserves undamaged. tissue.
