25. Early detection of metabolic and energy disorders by thermal time series stochastic complexity analysis
Maintenance of thermal homeostasis in rats fed a high-fat diet (HFD) is associated with changes in their thermal balance. The thermodynamic relationship between heat dissipation and energy storage is altered by the ingestion of high-energy diet content. Observation of thermal registers of core temperature behavior, in humans and rodents, permits identificati

26. Changes in the suprachiasmatic nucleus during aging: implications for biological rhythms
Animals have neural structures that allow them to anticipate environmental changes and then regulate physiological and behavioral functions in response to these alterations. The suprachiasmatic nucleus of the hypothalamus (SCN) is the main circadian pacemaker in many mammalian species. This structure synchronizes the biological rhythm based on photic informa

27. Human experimental anxiety: actual public speaking induces more intense physiological responses than simulated public speaking
Objectives: a) To perform a systematic and meta-analytic review to verify whether the Simulated Public Speaking Task (SPST) leads to a greater increase in self-rated anxiety than in physiological correlates of anxiety; and b) to compare the results obtained with the SPST with an actual public speaking task involving healthy volunteers. Methods: a) The Pub

28. Exercise training as a preventive tool for age-related disorders: a brief review
Aging populations are a worldwide phenomenon affecting both developed and developing countries. This issue raises serious concerns for both governments and the general population. Regular participation in physical activity and/or exercise training programs can minimize the physiological alterations that occur during aging and may contribute to improvements i

29. Biochemical adaptations of mammalian hibernation: exploring squirrels as a perspective model for naturally induced reversible insulin resistance
An important disease among human metabolic disorders is type 2 diabetes mellitus. This disorder involves multiple physiological defects that result from high blood glucose content and eventually lead to the onset of insulin resistance. The combination of insulin resistance, increased glucose production, and decreased insulin secretion creates a diabetic meta

30. Efeitos da Acupuntura, Eletroacupuntura e Metformina Sobre o Estresse Oxidativo, InflamaÃÃo e Glicemia em Ratas Sadias Submetidas a EstÃmulo EstrogÃnico / EFFECTS OF ACUPUNCTURE, ELETROACUPUNCTURE AND METFORMIN ON OXIDATIVE STRESS, INFLAMMATION AND BLOOD GLUCOSE IN HEALTHY RATS SUBMITTED TO ESTROGENIC STIMULATION
The physiological performance of cellular activity requires a balance between the production of free radicals and their deactivation by regulators and surge protectors. When this balance is broken, the oxidative stress takes place. Several experimental studies using estrogens to induction of ovarian and metabolic disorders, with emphasis on the polycystic ov

31. ESTRESSE INICIAL E CONDICIONAMENTO AO BAIXO OXIGÊNIO NO ARMAZENAMENTO EM ATMOSFERA CONTROLADA DE MAÇÃS ROYAL GALA / INITIAL STRESS AND CONDITIONING TO LOW OXYGEN IN CONTROLLED ATMOSPHERE STORAGE OF ROYAL GALA APPLES
O objetivo do presente trabalho foi avaliar métodos alternativos à atmosfera controlada convencional (AC) e dinâmica (ACD), na manutenção da qualidade de maçãs Royal Gala, em especial a ocorrência de distúrbios fisiológicos. Para tanto, avaliou-se o efeito do estresse inicial com baixo O2 na manutenção da qualidade de maçãs armazenadas em condi

32. Biological assessment (antiviral and antioxidant) and acute toxicity of essential oils from Drimys angustifolia and D. brasiliensis
The genus Drimys presents the widest geographical distribution of the Winteraceae family, which comprises seven genera and about 120 species. In Brazil, the genus is found from Bahia to Rio Grande do Sul and occur in two species, Drimys angustifolia Miers, and D. brasiliensis Miers, Winteraceae, popularly known as "casca-de-anta", characterized by the presen

33. Influência da época de colheita e do armazenamento em atmosfera controlada na qualidade da maçã 'Braeburn'.
Foi avaliado o efeito da época de colheita e das condições de armazenamento em atmosfera controlada sobre a firmeza da polpa, acidez titulável, oBrix e, principalmente, sobre a ocorrência de degenerescência da polpa em maçãs (Malus domestica cv. Braeburn). Os tratamentos consistiram na combinação da data de colheita (27/3/1997 e 9/4/1997) com condi

34. Efeito da adubação potássica na qualidade pós-colheita de maçãs 'Fuji'.
O objetivo deste trabalho foi avaliar o efeito da adubação potássica na composição mineral, qualidade e armazenabilidade de maçãs da cultivar Fuji. Os frutos utilizados foram provenientes de um experimento em que, durante nove anos, aplicaram-se doses crescentes de K2O no solo. As maçãs foram coletadas na safra 1999/2000 e armazenadas em atmosfera c

35. Use of response surface methodology to optimization of extraction of enzymes from pineapple pulp.
The enzymatic reactions are very important for food. They are responsíble for the formation of highly desirable cornpound, but can cause disorders and undesirable consequences. The physiological behaviour of vegetables and fruits is already known, so that most of its deterioration changes in flavour, colour and nutritional value are caused by enzymes of the

36. Negative addiction to exercise: are there differences between genders?
INTRODUCTION: Regular physical exercise has numerous benefits. However, there is a subset of the exercising population who may develop a compulsion to exercise excessively and who may, as a consequence, display physiological and psychological changes that have a direct influence on their quality of life. OBJECTIVE: Our objective was to determine if there are
