Stable isotopes are nonradioactive and can be safely administered to humans; yet, because of the isotopic difference, can be distinguished from the unlabeled moiety and thus trace the nutrient uptake and elimination. Stable isotope applications include measurement of nutrient absorption, determination of nutrient body stores, tracing routes of nutrient metabolism, measuring nutrient fluxes thro...

the iranian food consumption program (ifcp), a unique program in iran was developed to aim accurate calculation of nutrient intakes in relation to heart health investigation released in isfahan cardiovascular research center in march 1998 for the first time. the new versions came out along changes in computer technology. this interview-based program is designed to gather data through designed q...

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...

the relocation of nutrients and water fluxes to the forest floor varies spatially due to partition of rainfall into throughfall and stemflow by tree canopies. in this study, nutrient concentrations of rainfall and stemflow were measured for seven rainfall events in chaboksar area in the hyrcanian ecozone of iran composed of juglans regia linn and cup. sempervirens l. var. fastigiata where such ...

rapid changes in lifestyle and industrialization of communities have an important effect on food intake pattern of society. regarding the lack of enough data about dietary habits and nutrient intake of adolescents in our society, this study was performed in a group of adolescent girls in lahijan, north of iran. in this cross-sectional study, 400 high school girls aged 14-17 years selected by ra...

background: protein energy malnutrition and inflammation in hemodialysis (hd) patients often leads to the malnutrition inflammation complex syndrome or atherosclerosis malnutrition and inflammation related to the atherosclerotic cardiovascular disease.   this syndrome occurs in patients undergoing dialysis for a long time and is accounted as an important factor of mortality among these patients...

The improvement of New Zealands pastures over the last ISO years has increased the nutrient status of the soil as a result of the application of fertiliser, an increased soil organic matter content and increased biological activity. The grazing animal has also influenced the nutrient status of the soil by increasing the rate at which nutrients cycle between the soil, plants and animals. However...

Pistachio is one of the economically important horticultural crops in Iran. The main pistachio-producing areas in Iran are located at the edge of the desert and are affected by soil and water salinity. Water and nutrient uptake by the root decreases under saline conditions. In this study, the effects of foliar growth regulators applied at different times on the nutrient uptake and leaf nutrient...
