چکیده

Skeletal changes in pregnancy and lactation 253 fed rats. The spleens of rats with lower calcium intakes showed a weight gain during gestation which disappeared during the subsequent lactation. 7. Fertility of the dam and mothering instinct were not impaired, even in severe calcium deficiency. The weight of the young at birth and the number of young in a litter were not affected by the level of calcium intake by the dam. Weaning weights of young from severely deficient dams were lower.

Adaptive changes in energy expenditure during mild and severe feed restriction in the rat.

Using a new-generation open-circuit calorimeter capable of monitoring the cost of activity, and thereby both the real thermic effect of feeding (TEF) and basal metabolism in free-moving freely-feeding rats, we have reassessed the proposal that when food intake is restricted an adaptative reduction in energy expenditure participates in the achievement of energy balance. Total energy expenditure,...

Synchronous direct gradient layer and indirect room calorimetry.

A dual direct/indirect room-sized calorimeter is used at the Beltsville Human Nutrition Research Center to measure heat emission and energy expenditure in humans. Because the response times of a gradient layer direct calorimeter and an indirect calorimeter are not equivalent, the respective rate of heat emission and energy expenditure cannot be directly compared. A system of equations has been ...

ASSESSMENT OF ENERGY EXPENDITURE AND ENERGY INTAKE IN CRITICALLY ILL PATIENTS Energy Expenditure and Intake in Critically Ill Patients

Objective: To measure the energy expenditure (EE) of critically ill patients and to determine the adequacy of energy intake in terms of nitrogen balance. Research Methods & Procedures: Indirect calorimetry was performed in 17 critically ill patients under mechanical ventilation in order to calculate EE, and 24 h urinary nitrogen excretion was determined in order to calculate the nitrogen balanc...

An evaluation of the IDEEA™ activity monitor for estimating energy expenditure.

Objective estimates of activity patterns and energy expenditure (EE) are important for the measurement of energy balance. The Intelligent Device for Energy Expenditure and Activity (IDEEA) can estimate EE from the thirty-five postures and activities it can identify and record. The present study evaluated the IDEEA system's estimation of EE using whole-body indirect calorimetry over 24 h, and in...

Energy balance during acute respiratory exacerbations in children with cystic fibrosis.

Acute respiratory exacerbations have been proposed to contribute to the negative energy balance which causes undernutrition in cystic fibrosis. However, no studies have measured their effect on all components of energy balance. The aim of this study was to measure the effect of an acute respiratory exacerbation on energy balance. Fourteen children (six females, eight males, mean+/-SD age 9.9+/-...
