Mechanisms Involved in Human Thermogenesis
Energy expenditure in humans is partially understood. Sympathetic drive is an important stimulator of brown-adipose tissue-mediated increases in energy expenditure, and it is known that leptin-mediated pathways in part contribute to this. This thesis has sought to understand human energy …

DIETARY OBESITY, EXERCISE TRAINING, AND THERMOGENESIS IN RATS
<p>The exact contributions of changes in thermogenesis to the energy balance of either rats or humans is not known. There is some evidence that differences in post-prandial heat production (dietary-induced thermogenesis), can explain why some individuals gain weight easily when overeating and …

Transient intra- and extra-cellular thermometry as probes of thermogenesis
… steady-state substrate oxidation in stimulated thermogenesis. Our measurements demonstrate the utility of transient intracellular thermometry in better understanding the thermochemistry of stimulated mitochondrial metabolism. Using insights from intracellular thermometry, we theoretically …

The Effect of Non-exercise Activity Thermogenesis on subjects with Metabolic Syndrome
… activity is by promoting nonexercise activity thermogenesis (NEAT). NEAT represents 10% of daily human energy expenditure and is expended during daily life activities like mowing the lawn or climbing stairs. A lifestyle intervention study was conducted with 200 Qatari subjects identified with …

Examination of voluntary wheel running on markers of adipose thermogenesis in intact and ovariectomized female mice
… and body composition, key protein markers of thermogenesis and adipose tissue browning, and fluctuations in circulating and AT BDNF and receptor content. It was hypothesized VWR would either prevent or mitigate increases in adiposity due to OVX, enhance thermogenesis and AT browning in WAT …

Sex differences in diet-induced regulation of non-exercise activity thermogenesis in overweight and obese adults
Introduction: Reductions in physical activity energy expenditure (PAEE) and basal metabolic rate (BMR) have been proposed as factors that may hinder diet-induced body mass loss. Although diet-mediated changes in PAEE and BMR are subject to large inter-individual variability, research investigating …

The role of cone volatiles and thermogenesis in the pollination of Encephalartos cycads with particular reference to E.villosus
Pollination systems of cycads usually involve obligate mutualisms in which the cycad taxa depend on between one and three insect pollinators. Generally, the pollination periods of many cycad taxa are characterised by odour emissions in pollen shedding (male) and receptive (female) cones usually …

Estrogen Signaling in the Ventromedial Hypothalamus Modulates Adipose Tissue Metabolic Adaptation
… directly modulates brown adipose tissue (BAT) thermogenesis. We previously showed that an ERαvlVMH-originated neural circuit responds to changes in ambient temperature and nutritional states, suggesting a potential role of this neural circuit in metabolic adaptation. Here, we found that chronic …

SIMILAR EFFECTS OF COLD ADAPTATION AND EXERCISE TRAINING ON GROWTH, MAXIMUM AEROBIC CAPACITY, AND METABOLISM IN YOUNG RATS
<p>The exact processes underlying dietary-induced thermogenesis (DIT) are unknown. Current research has suggested that DIT and non-shivering thermogenesis (NST) may share common thermoregulatory pathways. If that is so, variables that are known to affect DIT should also affect NST, and vice versa. …

Exploring the metabolic role of GPR30 in mice
… indicating that GPR30 deficiency may promote thermogenesis and energy metabolism, resulting in the reduced fat depots and enhanced metabolic flexibility. For the third project, I further explored whether GPR30 is involved in regulating browning of adipose tissue and thermogenesis in mice. The …

Neuropeptide FF and Neuropeptide VF and their control in the regulation of energy homeostasis and glucose metabolism
… in energy expenditure and brown adipose tissue thermogenesis, however, shows impaired high fat diet-induced thermogenesis at thermoneutrality. Together this indicates a critical role of NPFF signalling in the thermos-sensory and dietary regulation of thermogenesis. Consistent with a role of NPFF …

MFSD7C: A Solute Carrier Linking Heme and Calcium in Mitochondrial Energy Metabolism
… show that the loss of MFSD7C stimulates cellular thermogenesis. The soluble N-terminal domain of MFSD7C contains conserved heme-binding motifs and directly binds two molecules of heme. We show that heme treatment of cells phenocopies the loss of MFSD7C, and that the N-terminal domain is essential …

Cold-Induced Metabolic Changes in Lean, NAG-1 Transgenic Mice
… activating brown adipose tissue which increases thermogenesis, the process of burning stored fats to generate heat. Cold exposure is a known way to activate brown adipose tissue through b3-adrenergic signaling. This signaling pathway causes an upregulation of thermogenesis in brown adipocytes and …

NOTCH SIGNALING REGULATES ADIPOGENESIS AND ENERGY METABOLISM
