A series of bio-rubber (BR) reactive tougheners for thermosetting epoxy resins was prepared by grafting renewable saturated fatty acids different chain lengths (C6-C14) onto epoxidized soybean oil (ESO) at varying molar ratios. The tunable nature the BR systems derives from architecture and functionality naturally occurring molecules. Control reactivity molecular weight degree length acid demon...

background & aims of the study: toluene-2, 4-diamine (tda) is a famous carcinogenic aromatic amine that is mostly employed as an intermediate in the production of dyes and toluene diisocyanate. in this study, degradation and mineralization of tda were investigated by uv/h2o2 process. materials & methods: this study is an experimental investigation on a laboratory scale. the study performed on s...

We have recently presented evidence that diamine oxidase is rcsponsiblc for a portion of the metabolism of histamine in several species (1, 2). This evidence is largely based on the alteration of histamine metabolism produced by compounds which are known to inhibit diamine oxidase in vitro. The inhibitors used were isonicotinylhydrazine (3) and aminoguanidine. The latter is reported to be the m...

Diamine oxidase is continuously released from the intestinal mucosa and carried to the circulation by the lymphatics. The effect of nutrients on this release was examined. Rats were prepared with duodenal and intestinal lymph cannulas. Test mixtures of lipid emulsions containing triolein, oleic acid, or tricaprylin and solutions of carbohydrate and protein were infused into the duodenum. The en...

The synthesis of the new potentially hexadentate ligands N,N'-bis(2,2'-bipyridin-6-ylmethyl)butane-1,4-diamine (bmbu), N,N'-bis(2,2'-bipyridin-6-ylmethyl)pentane-1,5-diamine (bmpt) and N,N'-bis(2,2'-bipyridin-6-ylmethyl)octane-1,8-diamine (bmot) from the condensation of 2,2'-bipyridine-6-carbaldehyde with the appropriate diamine (butane-1,4-diamine, pentane-1,5-diamine and octane-1,8-diamine, r...
