Maximum water temperatures in streams throughout the western USA typically occur in late summer and early autumn, coinciding with low stream flow. However, in the spring-fed Big Springs Creek in northern California, where constant-temperature groundwater springs provide relatively stable stream flow throughout the year, peak water temperatures and maximum diurnal variability occur in spring. We...

Helicobacter pylori :28 µg/mL).   (H. pylori) infection leads to different clinical and pathological outcomes in humans, including chronic gastritis, peptic ulcer disease and gastric neoplasia and even gastric cancer and its eradiation dependst upon multi-drug therapy. The most effective therapy is still unknown and prompts people to make great efforts to find better and more modern natural or ...

The effects of different growth regimes on gluconasturtiin concentration in watercress (Nasturtium officinale R. Br.) were investigated. Watercress plantlets at the 5th mature leaf stage (ca. 2 weeks old) were exposed to different day and night temperatures, to long (16 h) or short (8 h) days, to red (R) or far-red (FR) light given during the main long day photoperiod, and finally to R or FR li...

Abstract Cultures of Nasturtium officinale were cultivated in vitro under illumination with different wavelengths light-emitting diode (LED) light (white LED light—WLED, blue light—B, red light—R, 70% and 30% light—RB, 50% green, 35% 15% light—RBG, yellow, light—RBY, far red, light—RBfR, UV, light—RBUV, darkness—D), white fluorescent (WF)—control conditions. The study investigated the influence...

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...
