1. Our objectives were to measure total energy expenditure, the daily variation in total energy expenditure and the physical activity level in a group of HIV-positive subjects using the bicarbonate-urea method. The study also aimed to asses the practicalities of using the bicarbonate-urea technique in free-living conditions. 2. Total energy expenditure was measured with the bicarbonate-urea met...

Understanding the genetic factors of obesity requires consideration of the genetic basis of the underlying etiological factors including energy expenditure and substrate utilization. Genetic susceptibility studies suggest that altered energy expenditure and/or preferential substrate utilization are likely to be involved in the etiology of obesity. Twin and family studies suggest that there is a...

Both overnutrition and undernutrition affect energy metabolism, with overnutrition raising energy expenditure and undernutrition lowering it. Fever is a powerful stimulator of thermogenesis. In diseases such as cancer, AIDS, diabetes mellitus, and rheumatoid arthritis, whether energy expenditure is increased or decreased often depends on how advanced the disorder is. Early on, when the greater ...

BACKGROUND Physical activity has good influence on health. The physical activity of elderly people may decrease, because of the health problems or think that with aging sport activity should be reduced. OBJECTIVE The aim of the study was to assess a physical activity and energy expenditure of people in age 60 and more in the Koprzywnica district (Poland). MATERIAL AND METHODS 95 persons in ...

An exciting synergistic interaction occurs among researchers working at the interface of reproductive biology and energy homeostasis. Reproductive biologists benefit from the theories, experimental designs, and methodologies used by experts on energy homeostasis while they bring context and meaning to the study of energy homeostasis. There is a growing recognition that identification of candida...

the aim of the present study was to examine the effect of menstrual cycle on substrate metabolism, energy expenditure and performance during exhaustive incremental exercise in female students. for this purpose, 15 female students (mean age 21.17 ± 1.47 years, bmi 20.55 ± 1.71 kg/m2) participated voluntarily in this study. the design was adjusted in three stages: bleeding, follicular and the lat...

CONTEXT Exercise is associated with mortality benefits but simply expending energy through any activity in an individual's free-living environment may confer survival advantages. OBJECTIVE To determine whether free-living activity energy expenditure is associated with all-cause mortality among older adults. DESIGN, SETTING, AND PARTICIPANTS Free-living activity energy expenditure was assess...

Central oxytocin reduces food intake and increases energy expenditure. The ventromedial hypothalamic nucleus (VMN) is associated with energy balance and contains a high density of oxytocin receptors. We hypothesized that oxytocin in the VMN is a negative regulator of energy balance acting to reduce feeding and increase energy expenditure. To test this idea, oxytocin or vehicle was injected dire...

introduction: any rise in health expenditure is the main concern of householders and policymakers. a few studies have been conducted on assessing the determinants of expenditures and environmental quality from a macroeconomic point of view. this paper aimed to investigate the relationship between health expenditure and environmental quality in more than 114 developing countries between 1995 and...

It has been demonstrated that a vegetarian diet may be effective in reducing body weight, however, the underlying mechanisms are not entirely clear. We investigated whether there is a difference in resting energy expenditure between 26 vegetarians and 26 non-vegetarians and the correlation between some nutritional factors and inflammatory markers with resting energy expenditure. In this cross-s...
