Polypeptide assemblies cross-linked by S-S bonds (molecular mass>200 kDa) and single polypeptides folded with internal S-S cross-links (<41 kDa) have been detected by SDS/PAGE in particulate membranes and soluble extracts of developing cotyledons of nasturtium (Tropaeolum majus L.). When first prepared from fruit homogenates, these polypeptides were found to bind reversibly to UDP-Gal (labelled...

Nasturtium (Tropaeolum majus L.) oil contains the highest levels of erucic acid of known seed oils (75-80%). A significant portion of the acid is attached to the 2-position of the glycerol, and trierucin is a major component (ca. 50%) of the oil. Seeds from eleven varieties of commercially available garden nasturtium (T. majus) were screened for oil content, erucic acid levels and fatty acid di...

The fatty acid elongase [often designated FAE or beta-(or 3-) ketoacyl-CoA synthase] is a condensing enzyme and is the first component of the elongation complex involved in synthesis of erucic acid (22:1) in seeds of garden nasturtium (Tropaeolum majus). Using a degenerate primers approach, a cDNA of a putative embryo FAE was obtained showing high homology to known plant elongases. This cDNA co...

BACKGROUND Nasturtium officinale is a traditional herb that is used for diuresis. OBJECTIVES The aim of this study is to determine the effects of hydrophilic extract of Nasturtium officinale on ethylene glycol-induced renal stone in male Wistar rats. MATERIALS AND METHODS In this study 32 male Wistar rats were randomly divided in six groups and studied during 30 days. Two groups of negative...

OBJECTIVE Hyperlipidemia is a known complication of diabetes mellitus and predisposes to coronary heart disease. The lowering of total cholesterol and low density lipoprotein (LDL)-cholesterol should reduce the incidence of coronary disease. The aim of the present study was to examine the antihyperlipidemic and antidiabetic effects of the hydroalcoholic extract of watercress (Nasturtium officin...

background and objectives: nasturtium officinale w.t.aiton (brassicaceae) is used as an edible vegetable in various parts of iran. the aim of the present study was to investigate the protective activity of the methanolic extract of nasturtium officinale against gamma-radiation-induced hepatotoxicity in terms of histopathological changes. methods: male c57 mice were divided into 10 groups. group...

Watercress (Nasturtium nasturtium) is a medical plant containing diverse chemically-active substances with biological properties. The present study was conducted to investigate the immunomodulatory effects of watercress extract on immunological and hematological parameters of rainbow trout (Oncorhynchus mykiss). Fish were fed for 21 days with diet supplemented with 0.1% and 1% of watercress ext...
