We used a detailed analysis of feeding behavior to investigate the role of solanaceous alkaloids as sensory-based feeding deterrents for the Colorado potato beetle,Leptinotarsa decemlineata (Say). Experiments were conducted on three geographic, host-adapted populations of beetles to determine
This study was undertaken to investigate some cardiovascular effects of Hypoxis hemerocallidea Fisch & CA Mey (Hypoxidaceae) corm (African potato) aqueous extract in experimental animal paradigms. The effect of the corm aqueous extract (APE) on myocardial contractile performance was evaluated on
This study investigated the antidiarrhoeal activity of Hypoxis hemerocallidea corm aqueous extract (APE) on experimentally-induced diarrhoea, gastrointestinal motility, intestinal transit and enteropooling in rodents. H. hemerocallidea corm aqueous extract (APE, 50-400 mg/kg, p.o.) produced
Potatoes and tomatoes, members of the Solanaceae plant family, serve as major, inexpensive low-fat food sources providing for energy, high-quality protein, fiber, vitamins, pigments, as well as other nutrients. These crops also produce biologically active secondary metabolites, which may have both
Cholescintigraphy, using 99mTc-HIDA, was employed to determine the gallbladder emptying response to sham feeding of a steak and potato meal, and to compare it with the emptying responses to direct cholinergic stimulation by bethanechol and to ingestion of the test meal. The maximal cumulative
Many types of ocular trauma can be diagnosed and treated in the primary care office, particularly if a slit lamp is available. Treatment for corneal abrasions consists of applying a cycloplegic medication, antibiotic ointment, and a patch (unless a corneal ulcer is suspected). Iritis can be treated
The purpose of these studies was to determine the amount of saliva secreted in response to food in humans and to evaluate the effect of saliva on postprandial gastric acid secretion. Subjects chewed and spat out an appetizing steak and french-fried potato meal (modified sham feeding), with the
The potato cyst nematodes (PCN) Globodera pallida and G. rostochiensis are major pests of potatoes. The G. pallida (and G. rostochiensis) life cycle includes both diapause and quiescent stages. Nematodes in dormancy (diapause or quiescent) are adapted for long-term survival and are more resistant to
