Background Recently, our studies have shown that co-ingestion of carbohydrate and whey protein hydrolysate (WPH) is more effective for increasing post-exercise skeletal muscle glycogen content than ingestion of other protein sources (whey protein, casein hydrolysate, or branched chain amino acids). We have also shown that chronic feeding of whey protein increases glycogen contents in skeletal m...

24 Peripheral co-administration of amylin and leptin produces enhanced suppression of 25 food intake and body weight, but the central nuclei mediating these effects remain 26 unclear. As each of these peptides controls feeding via actions at the ventral 27 tegmental area (VTA), we tested the hypothesis that the VTA is a site of action for 28 the cooperative effects of leptin and amylin on energ...

Nutritional support in the elderly not only co-operates in pharmacological treatment but also very often is a primary therapy for their health. The type of artificial nutrition (AN) to use will depend on the present illness and the previous health record. Due to the fact that enteral feeding (EF) is less expensive and aggressive we should use EF whenever possible, leaving parenteral nutrition (...

Potato tuber disks, when treated with laminarin, a beta-1,3-glucooligosaccharide from Laminaria digitata, accumulate a hydroxycinnamoyl amide compound, N-p-coumaroyloctopamine (p-CO). The biosynthesis of p-CO was investigated by feeding experiments, in order to show that the precursors of N-p-coumaroyl and octopamine moieties of p-CO are L-phenylalanine and L-tyrosine, respectively. The treatme...

A system consisting of a flow-through chamber connected to a commercial infrared gas analysis system was developed to measure homopteran respiration during feeding. Using this system, respiration rates of 202 and 206 µmol CO(2) h(-1) g(-1) (4.96 and 5.04 ml CO(2) h(-1) g(-1)) were determined for whiteflies and cotton aphids, respectively, at 25 degrees C on diets containing 15% sucrose. These r...

Insect herbivores play a pivotal role in regulating plant production and community composition, and their role in terrestrial ecosystems is partly determined by their feeding behavior and performance among plants of differing nutritional quality. Historically, nitrogen (N) has been considered the primary limiting nutrient of herbivorous insects, but N is only one of many potential nutrients imp...
