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...

Arya Stark Instructor: Dr. Scott Oliver TA: Yashar Abdollahian Chem 151L, Section 01C Abstract. In this experiment, oxobis(2,4-pentanediono)vanadium(IV) is synthesized from a mixture of vanadium(V) oxide, sulfuric acid, acetylacetone, and ethanol. The reaction took place over heat, and came to completion when the original mixture turned blue. The solution was then filtered, neutralized, and rec...

Two types of photoinitiator are considered: (1) transition metal complexes (mainly carbonyls), (2) chelates of transition metals. In systems of type (1) the metal is in a low oxidation state and an organic halide is generally, but not always, present; on thc other hand, in (2) the metal is initially in a high oxidation state. Comparison between photoand thermal-initiation is made for each type....

Increased plasma histamine levels were associated with significantly lowered diamine and type B monoamine oxidase activities in platelet-rich plasma of atopic eczema (AE) patients. The diamine oxidase has almost normal cofactor levels (pyridoxal phosphate and Cu(2+)) but the cofactor levels for type B monoamine oxidase (flavin adenine dinucleotide and Fe(2+)) are lowered. The biogenic amines pu...

Tetradentate acyclic compartmental Schiff base ligand with N2O2 compartment afford suitable coordination environment for large variety of metal ions. This type ligands can easily be synthesized by [2+1] condensation a carbonyl compounds diamine. Several complexes have been reported from the single- and double-compartment which are products salicylaldehyde, 2-hydroxyacetophenone, 3-methoxysalicy...
