OBJECTIVE To identify predictors of eating in the absence of hunger (EAH) in low-income toddlers, describe affect during EAH, test EAH as a predictor of body mass index (BMI), and examine the type of food eaten as a predictor of BMI. METHODS EAH, indexed as kilocalories (sweet, salty, and total) of palatable foods consumed after a satiating meal, was measured (n = 209) at ages 21, 27, and 33 ...

Heat evolved by isolated soybean (Glycine max cv Clark) nodules was measured to estimate more directly the metabolic cost associated with the symbiotic N(2) fixation system. A calorimeter constructed by modifying standard laboratory equipment allowed measurement on 1 gram of detached nodules under a controlled gas stream. Simultaneous gas balance and heat output determinations were made.There w...

The effects of cyanide, anoxia, and temperatures varying from 2 to 42 C on the cell membrane electropotential difference (PD) of washed and freshly excised corn roots have been determined. Respiration rates of freshly excised root segments in response to cyanide and to varying temperatures were also measured. The cell membrane PD of roots which had been washed for 12 to 15 hours was almost inse...

INTRODUCTION Previous studies have shown that physical activity (PA) in COPD is associated with a better quality of life and less morbidity and mortality. Our aim was to study the daily PA in the lives of stable COPD patients, outside the setting of a pulmonary rehabilitation program. MATERIAL AND METHODS Observational, descriptive and transversal multi-center study in patients with stable CO...

The effect of temperature on the rate of proton transport and ATP hydrolysis by plasma membrane (PM) and tonoplast (TN) ATPases from barley (Hordeum vulgare L. cv CM 72) roots were compared. Rates of proton transport were estimated using the fluorescent amine dyes quinacrine and acridine orange. The ratio between rate of transport and ATP hydrolysis was found to depend on the dye, the temperatu...

During 2011-2014, on average, 7.3% of boys' and 7.2% of girls' total daily calories were obtained from SSBs compared with 6.9% for men and 6.1% for women. For men, women, and girls, the percentage of total daily kilocalories from SSBs declined as income level increased. For boys, the percentage of total daily kilocalories was lower for those in the highest income group than in the other income ...

Changes in temperature and body heat were measured in 30 patients. Despite the warming of most fluids given intravenously, all the patients ventilated with dry anaesthetic gases became cooler, with an average heat loss of 12.4 kilocalories per hour. In a group to whom the gases were delivered saturated at body temperature, the average hourly loss was 1.5 kilocalories. This difference is in agre...

Modified quantum mechanical calculations predict the binding enthalpies of saccharide inhibitors of lysozyme to within a few kilocalories of experimental measurements.

The obesity epidemic has triggered a need for novel methods for measuring eating activity in free-living settings. Here, we introduce a bite-count method that has the potential to be used in long-term investigations of eating activity. The purpose of our observational study was to describe the relationship between bite count and energy intake and determine whether there are sex and body mass in...

Data from the National Health and Nutrition Examination Survey In 2007-2008 the average energy intake for men was 2,504 kilocalories (kcals) and for women it was 1,771 kcals. The average carbohydrate intake was 47.9% of total kilocalories (% kcals) for men and 50.5% kcals for women; average protein intake was 15.9% kcals for men and 15.5% kcals for women; average total fat intake was 33.6% kcal...
