The relationship between postprandial blood glucose levels and meal viscosity was studied by adding various combinations of hydroxypropylmethylcellulose to glucose solutions and administering them to female mongrel dogs. Glucose was administered as 5% or 20% solutions in water. Hydroxypropyl-methylcellulose was dissolved in the glucose solutions to yield low (5000 cP measured at 37 degrees C an...

fifteen kinds of local wetland plants in taihu lake region of china were investigated on their respective growth conditions, biomass allocations and nutrient uptake capacities. the test plants were cultured in 3 l nutrient solutions for 28 days with nh4 +-n, no3 --n and p concentrations of 38.5, 132.8 and 10 mg/l, respectively. mean species total biomass ranged from 1.2-21.6 g/plant with a...

Foraging animals regulate their intake of macronutrients such as carbohydrates and proteins. However, regulating the intake of these two macronutrients can be constrained by the nutrient content of available food sources. Compensatory foraging is a method to adjust nutrient intake under restricted nutrient availability by preferentially exploiting food sources that contain limiting nutrients. H...
