The nuclear receptor REV-ERBα is part of the molecular clock mechanism and thought to be involved in a variety of biological processes within metabolically active peripheral tissues as well. To investigate whether Rev-erbα (also known as Nr1d1) in the brain plays a role in the daily variations of energy metabolism, feeding behaviour and the sleep-wake cycle, we studied mice with global (GKO) or brain (BKO) deletion of Rev-erbα. Mice were studied both in a light-dark cycle and constant darkness, and 24-h variations of Respiratory quotient (RQ) and energy expenditure, as well as the temporal patterns of rest-activity and feeding behavior were recorded...

Habitual exercise training is recommended to young people for their health promotion, but adherence may be influenced by atmospheric temperature (T a ) if performed outdoors. We compared the adherence to and the effects of a home-based interval walking training (IWT) program on sedentary female college students between winter and summer. For summer training over 176 days, 48 subjects (18-22 years old) were randomly divided into two groups: the control group (CNTsummer, n = 24), which maintained a sedentary lifestyle as before, and the IWT group (IWTsummer, n = 24), which performed IWT while energy expenditure was monitored by accelerometry...

To determine whether age affects cycling efficiency and the energy cost of walking (Cw), 190 healthy adults, ages 18-81 yr, cycled on an ergometer at 50 W and walked on a treadmill at 1.34 m/s. Ventilation and gas exchange at rest and during exercise were used to calculate net Cw and net efficiency of cycling. Compared to the 18-40 yr age group (2.17 ± 0.33 J/kg/m), net Cw was not different in the 60-64 yr (2.20 ± 0.40 J/kg/m) and 65-69 yr (2.20 ± 0.28 J/kg/m) age groups, but was significantly (P < 0...

OBJECTIVE: The cocaine- and amphetamine-regulated transcript (CART) codes for a pivotal neuropeptide important in the control of appetite and energy homeostasis. However, limited understanding exists for the defined effector sites underlying CART function, as discrepant effects of central CART administration have been reported. METHODS: By combining Cart-cre knock-in mice with a Cart adeno-associated viral vector designed using the flip-excision switch (AAV-FLEX) technology, specific reintroduction or overexpression of CART selectively in CART neurons in the arcuate nucleus (Arc) and lateral hypothalamic area (LHA), respectively, was achieved...

Aberrant neuronal DNA methylation patterns have been implicated in the promotion of obesity development, but the role of neuronal DNA methyltransferases (Dnmts; enzymes that catalyze DNA methylation) in energy balance remains poorly understood. We investigated whether neuronal Dnmt1 regulates normal energy homeostasis and obesity development using a novel Dnmt1 knockout mouse model, Dnmt1fl/fl Synapsin1Cre (ND1KO), which specifically deletes Dnmt1 in neurons.Neuronal Dnmt1 deficiency reduced adiposity in chow-fed mice and attenuated obesity in HFD-fed male mice...

The purpose of this study was to identify and compare energy requirements specific to Special Operations Forces in field training, in both cool and hot environments. Three separate training sessions were evaluated, two in a hot environment (n=21) and one in a cool environment (n=8). Total energy expenditure was calculated using doubly-labeled water. Dietary intake was assessed via self-report at the end of each training mission day, and macronutrient intakes were calculated. Across the three missions, mean energy expenditure (4,618 ± 1,350 kcal/day) exceeded mean energy intake (2,429 ± 838 kcal/day) by an average of 2,200 kcal/day...

This study aimed to analyze the biomechanical consequences of reducing the base of support in patients with ataxia. Specifically, we evaluated the spatio-temporal parameters, upper- and lower-body kinematics, muscle co-activation, and energy recovery and expenditure. The gaits of 13 patients were recorded using a motion analysis system in unperturbed and perturbed walking conditions. In the latter condition, patients had to walk using the same step width and speed of healthy controls. The perturbed walking condition featured reduced gait speed, step length, hip and knee range of motion, and energy recovery and increased double support duration, gait variability, trunk oscillation, and ankle joint muscle co-activation...

Highly specialized diving birds display substantial dichotomy in neck length with, for example, cormorants and anhingas having extreme necks, while penguins and auks have minimized necks. We attached acceleration loggers to Imperial cormorants Phalacrocorax atriceps and Magellanic penguins Spheniscus magellanicus, both foraging in waters over the Patagonian Shelf, to examine the difference in movement between their respective heads and bodies in an attempt to explain this dichotomy. The penguins had head and body attitudes and movements that broadly concurred throughout all phases of their dives...

Energy expenditure is a target gaining recent interest for obesity treatment. The antiobesity effect of vanillic acid (VA), a well-known flavoring agent, was investigated in vivo and in vitro High-fat diet (HFD)-induced obese mice and genetically obese db/db mice showed significantly decreased body weights after VA administration. Two major adipogenic markers, peroxisome proliferator activated receptor γ (PPARγ) and CCAAT/enhancer-binding protein α (C/EBPα), were reduced while the key factor of energy metabolism, AMPKα, was increased in the white adipose tissue and liver tissue of VA-treated mice...

Securing accurate measurements of dietary intake across populations is challenging. Of the methods, self-reported 24-h recalls are often used in low-income countries (LICs) because they are quick, culturally sensitive, do not require high cognitive ability, and provide quantitative data on both foods and nutrients. Measuring intakes via 24-h recalls involves 1) collecting data on food intakes, 2) the appropriate use of relevant food-composition data for calculating nutrient intakes, and 3) statistically converting observed intakes to "usual intakes" for evaluating nutrient adequacy or relations between foods and nutrients and health outcomes...

Prader-Willi syndrome (PWS) is a rare genetic disorder associated with excessive weight gain. Hyperphagia associated with PWS may result in higher energy intake, but alterations in energy expenditure may also contribute to energy imbalance. The purpose of this critical literature review is to determine the presence of alterations in energy expenditure in individuals with PWS. Ten studies that measured total energy expenditure (TEE), resting energy expenditure (REE), sleep energy expenditure (SEE), activity energy expenditure (AEE), and diet induced thermogenesis (DIT) were included in this review...

The goal of this study was to measure arterial amino acid levels in patients with chronic heart failure (CHF), and relate them to left ventricular function and disease severity. Amino acids (AAs) play a crucial role for heart protein-energy metabolism. In heart failure, arterial AAs, which are the major determinant of AA uptake by the myocardium, are rarely measured. Forty-one subjects with clinically stable CHF (New York Heart Association (NYHA) class II to IV) were analyzed. After overnight fasting, blood samples from the radial artery were taken to measure AA concentrations...

Low energy availability can place athletes at increased risk of injury and illness and can be detected by a low metabolic rate. The lowest metabolic rate is captured at the bedside, after an overnight fast and termed inpatient REE. Measurements done in a laboratory with a shorter overnight fast are termed outpatient REE. Although important to know what the lowest energy expenditure, a bedside measure and/or 12 h fast is not always practical or logistically possible particularly when you take into account an athlete's training schedule...

Adipose tissue expansion (ATE) progresses rapidly during postnatal life, influenced by both prenatal maternal factors and postnatal developmental cues. The ratio of n-6 relative to n-3 polyunsaturated fatty acids (PUFA) is thought to regulate perinatal adipogenesis, but the cellular mechanisms and long-term effects are not well understood. We lowered the fetal and postnatal n-6/n-3 PUFA ratio exposure in wildtype offspring, under standard maternal dietary fat amounts, to test effects of low n-6/n-3 ratios on offspring adipogenesis and adipogenic potential...

Low-protein (LP) containing diets can induce overeating in rodents and possibly in humans in an effort to meet protein requirement but the consequences on energy expenditure (EE) are unclear. The present study evaluated the changes induced by reducing dietary protein from 20% to 6%, using either soy protein or casein, on energy intake, body composition and EE in mice housed at 22°C or at 30°C (thermal-neutrality). LP feeding increased energy intake and adiposity, more in soy fed than in casein fed mice, but also increased EE thus limiting fat accumulation...

Short chain fatty acids (SCFAs), produced from fermentation of dietary fibre by the gut microbiota, have been suggested to modulate energy metabolism. Previous work using rodent models have demonstrated that oral supplementation of the SCFA propionate raises resting energy expenditure (REE) by promoting lipid oxidation. The objective of this study was to investigate the effects of oral sodium propionate on REE and substrate metabolism in humans. Eighteen healthy volunteers (9 females and 9 males; Age: 25±1 y; Body Mass Index: 24...

With an exponential increase in urbanization and industrialization, water pollution is an inevitable consequence of relatively lagging wastewater treatment facilities. The conventional activated sludge process for wastewater treatment primarily emphasizes the removal of harmful substances to maintain increasingly stringent effluent discharged standards, which is considered an energy-intensive technique. Therefore, innovative and sustainable wastewater treatment should pay more attention to energy and resource recovery in dealing with fossil fuel depletion, global-scale energy security, and climate change...

Physical activity improves the quality of life and decreases the risk of several diseases (i.e. stroke, hypertension, myocardial infarction, obesity, and malignancies). Skeletal muscles are considered as an endocrine organ that produces myokines characterized by a paracrine or endocrine activity. Irisin is a circulating hormone-like myokine and is secreted as a product of fibronectin type III domain-containing protein 5 from skeletal muscle in response to exercise. This molecule regulates the energy metabolism and acts in adipose tissue, bones, and nervous system...

The gut microbiota has emerged as an environmental factor that modulates the host's energy balance. It increases the host's ability to harvest energy from the digested food, and produces metabolites and microbial products such as short-chain fatty acids, secondary bile acids, and lipopolysaccharides. These metabolites and microbial products act as signaling molecules that modulate appetite, gut motility, energy uptake and storage, and energy expenditure. Several findings suggest that the gut microbiota can affect the development of obesity...

Birds and mammals have evolved many thermal adaptations that are relevant for bioinspired design of temperature control systems and energy management in buildings. Similar to many buildings, endothermic animals generate internal metabolic heat, are well insulated, regulate their temperature within set limits, modify microclimate and adjust thermal exchange with their environment. Here, we review the major components of animal thermoregulation in endothermic birds and mammals that are pertinent for building engineering, in a world where climate is changing and reduction in energy use is needed...
