Flavonoid biosynthesis in Dianthus caryophyllus L. is early regulated during interaction with Fusarium oxysporum f. sp. dianthi.

Rooted cuttings from two carnation (Dianthus caryophyllus L.) cultivars showing contrasting responses to the vascular wilt caused by Fusarium oxysporum f. sp.

Glucosinolate composition of Colombian accessions of mashua (Tropaeolum tuberosum Ruíz & Pavón), structural elucidation of the predominant glucosinolate and assessment of its antifungal activity.

Background: The content of individual and total glucosinolates in 65 mashua tuber accessions (Tropaeolum tuberosum) from the germplasm bank at Universidad Nacional de Colombia was determined by reverse phase high-performance liquid chromatography on enzymatically desulfated extracts. The predominant glucosinolate was identified and the possible structure of the glucosinolate present in lower proportion was postulated from evidence obtained by high-performance liquid chromatography/mass spectrometry, H and C nuclear magnetic resonance and bi-dimensional experiments. The biological action of the hydrolysis products generated from the glucosinolates in the accessions that showed a higher content of these compounds was assessed in the presence of Fusarium oxysporum f.

Advances in the endoscopic management of pancreatic collections.

Treatment of pancreatic collections has experienced great progress in recent years with the emergence of alternative minimally invasive techniques comparing to the classic surgical treatment. Such techniques have been shown to improve outcomes of morbidity vs surgical treatment. The recent emergence of endoscopic drainage is noteworthy.
