Electropolymerization of novel gallium Schiff-base complexes results in conducting metallopolymers containing either coordinatively saturated or unsaturated gallium metal centers. Depending on the chemical coordination of the metal centers, the embedded metal ions can act as seed points for the direct growth of size-controlled gallium sulfide nanoparticles in a conducting polymer, yielding a hy...

BACKGROUND AND AIMS The role of Helicobacter pylori and atrophic gastritis in the pathogenesis of gastric lesions in familial adenomatous polyposis (FAP) has not been clarified. PATIENTS Thirty one patients with FAP. METHODS The presence of fundic gland polyposis (FGP) and gastric adenoma (GA) was determined by upper endoscopy with biopsies. The degree of gastric mucosal atrophy and H pylor...

The changes in the contents of free and bound gibberellin-like activity (GA) of Tulipa gesneriana L. cv. Ralph during development under 2 temperature conditions were studied. The results show that the content of free GA of bulbs grown at 18 degrees increased by 67% over the initial level during development. The bound GA showed a slight initial increase and was followed by a rapid decrease. In c...
