Nutrient intake was calculated from an established nutrient database.
Empirical regression models that predict algal biomass as a function of nutrients are often used for establishing nutrient concentrations that are protective of stream conditions.
The greatest strength of the pulse-feeding method is that, while more involved than bacterial clearing, it directly establishes nutrient utilization and is independent of the culture medium.
Dietary intake estimates for various fatty acids were derived from the FFQ by summing the product of nutrient content of each food item derived from a previously established nutrient database [ 30, 31], portion size, and frequency of consumption.
In summary, these results confirm that MCH neurons are both necessary and sufficient for sensing the nutrient value of sucrose and suggest that these neurons play a critical role in establishing nutrient preference.
However, we felt it was important to include TN in these analyses because of its importance in establishing nutrient criteria (Dodds and Welch 2000) and because other available parameters, such as dissolved inorganic nitrogen, can be unsuitable substitutes (Dodds 2003).
Here we show that the presence of the specific ladderane PC lipid at different depths in a sediment core correlates well with established nutrient and oxygen profiles in sediments as well as profiles of anammox bacterial abundance estimated using molecular techniques including FISH and qPCR [ 33].
They used questionnaires to establish their nutrient intake, both food and supplements, and established cases of PMS by clinical diagnosis.
Originally applied by the IOM to establish ULs, nutrient risk assessment can be used to identify ULs for bioactive substances.
In summary, these studies with Slc6a14-knockout mice reported by Babu et al. [ 21] clearly establish that nutrient transporters deserve greater attention as a novel and effective means to target the constitutive anabolism of cancer cells.
