1. Distant populations of a Xanthosoma (Araceae) species have different floral scents but the same cyclocephaline beetle pollinators
ABSTRACT We report on the reproductive biology, pollinators, and thermogenesis of the widely distributed Araceae species, Xanthosoma striatipes. We analyzed the floral scent in one population and compared it to a previous study. Xanthosoma striatipes was studied at three sites in Brazil, São Paulo, Minas Gerais and Maranhão. The results showed constancy of

2. Higher increase degree of FGF21 post long-term interdisciplinary weight loss therapy preserves the free fat mass and rest metabolic rate in adolescents with obesity
ABSTRACT Objective Fibroblast growth factor 21 (FGF21) is among the activators that can stimulate thermogenesis in the white adipose tissue and brown adipose tissue. People with obesity have elevated blood levels of FGF21, but also develop resistance to its action, impairing its beneficial role. Inversely, clinical treatments to weight loss has been pointe

3. Effect of the fatty acid composition of meals on postprandial energy expenditure: a systematic review
RESUMO O desequilíbrio energético produzido pelo aumento da ingestão calórica e/ou diminuição do gasto energético provoca obesidade. Sem embargo, a composição de ácidos graxos da dieta pode afetar diferencialmente o metabolismo, tendo um papel no desenvolvimento da obesidade. OBJETIVO Determinar os efeitos de diferentes tipos de ácidos graxos e

4. Neonatal tobacco smoke reduces thermogenesis capacity in brown adipose tissue in adult rats
Maternal smoking is a risk factor for progeny obesity. We have previously shown, in a rat model of neonatal tobacco smoke exposure, a mild increase in food intake and a considerable increase in visceral adiposity in the adult offspring. Males also had secondary hyperthyroidism, while females had only higher T4. Since brown adipose tissue (BAT) hypofunction i

5. Impact of free thyroxine levels and other clinical factors on bare metal stent restenosis
ABSTRACT Objective Thyroid hormones have both direct and indirect effects on thermogenesis such as modulating vascular smooth muscle cell proliferation. However, the influence of more subtle changes in thyroid hormones on coronary atherosclerosis remains a matter of speculation. Smooth muscle cells play a crucial role in the pathogenesis of in-stent resten

6. The reproductive biology of the early-divergent genus Anaxagorea (Annonaceae), and its significance for the evolutionary development of the family
ABSTRACT Data of six studied Neotropical Anaxagorea species are analyzed and discussed with respect to the population structure, flowering phenology, flower morphology, anthesis, scent emission, thermogenesis, floral visitors, breeding system, fruit-set and seed dispersal. The probably reason for the patchy distribution of small populations of Anaxagorea spe

7. Importância do tecido adiposo marrom na ativação da termogênese induzida pela injeção central do C75, um inibidor da ácido graxo sintase / Importance of brown adipose tissue in the activation of thermogenesis induced by central injection of C75, a fatty acid synthase inhibitor
C75, a synthetic inhibitor of fatty acid synthase, causes anorexia and weight loss in rodents, but the underlying mechanisms are not totally known. Thus, the hypothesis tested in this work was that brown adipose tissue (BAT), an organ with important role for control of thermogenesis, could be involved in the anti-obesity effects of fatty acid synthase inhibi

8. Tratamento com topiramato melhora a sensibilidade hipotalâmica à insulina em camundongos obesos / Topiramate improves insulin sigmalling the hypothalamus of mice on high-fat diet
Topiramate (TPM) is an anticonvulsant drug used for the treatment of epilepsy and prophylaxis of migraine. Weight loss is a frequently side effect reported in patients and animal models treated with TPM. In animal models topiramate may increase levels of hypothalamic corticotropic-releasing hormone (CRH), which is an anorexigenic neuropeptide and may decreas

9. Postprandial thermogenesis in Bothrops moojeni (Serpentes: Viperidae)
Snakes that can ingest prey that are proportionally large have high metabolic rates during digestion. This great increase in metabolic rate (specific dynamic action - SDA) may create a significant augment in the animal's body temperature. The present study investigated postprandial thermogenesis in Bothrops moojeni. Briefly, two groups of snakes were fed mea

10. Nest thermoregulation in Polybia scutellaris (White) (Hymenoptera: Vespidae)
Polybia scutellaris (White) builds large nests characterized by numerous spiny projections on the surface. In order to determine whether or not the nest temperature is maintained because of homeothermic conditions of the nest individuals or otherwise, we investigated the thermal conditions within the nests built by P. scutellaris. We measured the temperature

11. Efeitos da qualidade proteica no apetite e metabolismo energético de indivíduos eutróficos
OBJECTIVE: The purpose of this study was to compare the effects of consumption of different protein sources on food intake and energy expenditure in normal weight subjects. SUBJECTS AND METHODS: Breakfast preparations (casein, soy protein, whey protein or control) were ingested during seven consecutive days. Appetite, food intake, and energy expenditure were

12. Role of TR in diet- induced thermogenesis / Papel do TR na termogênese induzida pela dieta.
O hormônio tireoideano (T3) desempenha papel importante no desenvolvimento, no crescimento e no metabolismo celular. Um dos seus principais efeitos é a ativação do metabolismo basal, contribuindo de forma importante com a regulação do peso corporal, enquanto diminui os níveis plasmáticos de triglicérides e colesterol. A ativação seletiva do recept
