Associação entre a aptidão cardiorrespiratória e a circunferência da cintura, pressão arterial, e glicemia em adolescentes

A relação entre aptidão cardiorrespiratória e um menor perfil de risco cardiovascular tem sido demonstrado em crianças e adolescentes (Janssen & Leblanc, 2010; 2006; Kriemler et al., 2008). Objetivo: verificar a associação entre o consumo máximo de oxigénio ( 2max) e a circunferência da cintura (CC), pressão arterial sistólica (PAS), pressão arterial diastólica (PAD) e glicemia em adolescentes utilizando a base de dados do projeto Rastresaúde. Método: este ro eto tin a co o ob etivo ava iar os rinci ais indicadores de sa de cardiovascu ar e inc u a as vari veis 2max A A e ice ia. ontudo nesse ro eto o 2max tinha sido obtido através do chester step test (CST) ue não estava va idado ara ado escentes. este sentido oi rea i ado u estudo re i inar co o ob etivo de estudar a associação entre va ores do 2max estimados utilizando o CST e o teste do Vaivém que está validado para adolescentes (Leger, Mercier, Gadoury, & Lambert, 1988). Pretendíamos com este objetivo poder eventualmente utilizar, os va ores do 2max da referida base de dados. endo-se veri icado u a associação estatistica ente si ni icativa orte e ositiva entre os va ores de 2max obtidos utilizando o CST e o teste Vaivém para o sexo masculino, r=0,92, p<0,05 e para o sexo feminino, r=0,78, p<0,05 decidimo-nos e a uti i ação da base de dados do astresa de. este sentido a re erida base de dados oi uti i ada ara investi ar a associação do 2max com a CC, PAS, PAD e glicemia em adolescentes. Resultados: verificou-se nos indivíduos do sexo feminino uma associação inversa e estatistica ente si ni icativa entre o 2max e a A r - 1 5 entre o 2max e a A r - 1 5 e entre o 2max e a CC, r=-0,182, p< 5. ara os indiv duos do se o ascu ino veri icou-se u a associação inversa e estatistica ente si ni icativa a enas entre o 2max e a CC, r=-0,229, p<0,05 sendo que todas as associações encontradas foram consideradas fracas, r<0,3 (Field, 2005). Conclusão: os resultados do estudo sugerem uma associação inversa entre o 2max e a PAS, PAD e CC em adolescentes do sexo feminino e entre 2max e a CC em adolescentes do sexo masculino. Dada a escassez de estudos e derivado ao aumento da prevalência dos fatores de risco associados às doenças cardiovasculares na infância e adolescência é relevante realizar mais estudos na população jovem.

La responsabilidad social del Estado frente a las familias víctimas del conflicto internacional, generado por los efectos de las fumigaciones en la parroquia General Farfán

La presente tesis, es un estudio descriptivo ex post facto, en torno a la responsabilidad social del Estado Ecuatoriano, frente a las familias víctimas del conflicto internacional. Confronta dos paradigmas: el que maneja el gobierno colombiano, se basa en la lógica del mercado, promueve la duda razonable, el impacto aceptable, y el desconocimiento del rol humano o ecológico; el otro paradigma, asumido por el gobierno ecuatoriano, se fundamenta en la lógica humanista, defiende la ecología, valida el testimonio humano, protege la salud de las personas y la calidad del medio ambiente a mas de relacionar esta problemática con las determinantes sociales y los derechos humanos. Estos paradigmas los confrontaremos a partir del estudio de los impactos de las fumigaciones en la parroquia General Farfán del Cantón Lago Agrio, provincia de Sucumbíos, situación que se agravó por la ausencia de la institucionalidad del Estado, la misma que se volvió crítica a partir del inicio de las aspersiones con glifosato, y el consiguiente deterioro del medio ambiente que contribuyó al aumento de la pobreza y la exclusión. Además, del incremento de las FFAA y policiales en la frontera norte agudizó la tensión en estas comunidades; el Estado ecuatoriano, se limitó a desplazar y abastecer a las fuerzas armadas, como responsables de la seguridad de sus fronteras, pero desatendió a la población civil para la cual no existen propuestas de inversión social. Se violentó con ello, normas del Derecho Internacional, principios del Derecho Internacional Ambiental y de los Derechos Humanos. El abandono a esta población, da lugar a calificarlos como personas ambientalmente desplazadas (PAD), en situación de riesgo lo que nos lleva hacer una reflexión sobre esta condición, en torno a los desplazados ambientales jurídicamente no reconocidos.

Characterization and in vitro digestibility of bovine beta-lactoglobulin glycated with galactooligosaccharides

Galactooligosaccharides (GOS) are well-known prebiotic ingredients which can form the basis of new functional dairy products. In this work, the production and characterization of glycated beta-lactoglobulin beta-LG) with prebiotic GOS through the Maillard reaction under controlled conditions (a(w) = 0.44, 40 degrees C for 23 days) have been studied. The extent of glycation of beta-LG was evaluated by formation of furosine which progressively increased with storage for up to 16 days, suggesting that the formation of Amadori compounds prevailed over their degradation. RP-HPLC-UV, SIDS-PAGE, and IEF profiles of beta-LG were modified as a consequence of its glycation. MALDI-ToF mass spectra of glycated beta-LG showed an increase of up to similar to 21% in its average molecular mass after storage for 23 days. Moreover, a decrease in unconjugated GOS (one tri-, two tetra-, and one pentasaccharide) was observed by HPAEC-PAD upon glycation. These results were confirmed by ESI MS. The stability of the glycated beta-LG to in vitro simulated gastrointestinal digestion was also described and compared with that of the unglycated protein. The yield of digestion products of glycated beta-LG was lower than that observed for the unglycated protein. The conjugation of prebiotic carbohydrates to stable proteins and peptides could open new routes of research in the study of functional ingredients.

One’s own soundtrack: affective music synthesis

Computer music usually sounds mechanical; hence, if musicality and music expression of virtual actors could be enhanced according to the user’s mood, the quality of experience would be amplified. We present a solution that is based on improvisation using cognitive models, case based reasoning (CBR) and fuzzy values acting on close-to-affect-target musical notes as retrieved from CBR per context. It modifies music pieces according to the interpretation of the user’s emotive state as computed by the emotive input acquisition componential of the CALLAS framework. The CALLAS framework incorporates the Pleasure-Arousal-Dominance (PAD) model that reflects emotive state of the user and represents the criteria for the music affectivisation process. Using combinations of positive and negative states for affective dynamics, the octants of temperament space as specified by this model are stored as base reference emotive states in the case repository, each case including a configurable mapping of affectivisation parameters. Suitable previous cases are selected and retrieved by the CBR subsystem to compute solutions for new cases, affect values from which control the music synthesis process allowing for a level of interactivity that makes way for an interesting environment to experiment and learn about expression in music.

Experimental model of the interfacial instability in aluminium reduction cells

A solution has been found to the long-standing problem of experimental modelling of the interfacial instability in aluminium reduction cells. The idea is to replace the electrolyte overlaying molten aluminium with a mesh of thin rods supplying current down directly into the liquid metal layer. This eliminates electrolysis altogether and all the problems associated with it, such as high temperature, chemical aggressiveness of media, products of electrolysis, the necessity for electrolyte renewal, high power demands, etc. The result is a room temperature, versatile laboratory model which simulates Sele-type, rolling pad interfacial instability. Our new, safe laboratory model enables detailed experimental investigations to test the existing theoretical models for the first time.

Thermogenic and metabolic consequences of thyroid hormone treatment in brown and white adipose tissue

Male rats were treated with triiodothyronine in the drinking water for 12 days. In vitro rates of isoprenaline stimulated lipolysis were significantly greater in brown but not white adipose tissue. Rates of [14C]glucose incorporation into triacylglycerols were significantly reduced in BAT (brown adipose tissue) and WAT (white adipose tissue) under basal and isoprenaline stimulated conditions. In a second experiment, hyperthyroid animals showed impaired weight gain, despite increased food intake during 19 days' treatment. Energy expenditure on days 5 and 12, and BAT core temperature differences (TBAT - TCORE) on day 19, were significantly greater than in control animals. Epididymal white fat pad weight was reduced and interscapular brown fat pad weight increased by triiodothyronine treatment.

Stable reduced-order models for discrete-time systems

The Routh-stability method is employed to reduce the order of discrete-time system transfer functions. It is shown that the Routh approximant is well suited to reduce both the denominator and the numerator polynomials, although alternative methods, such as PadÃ�Â(c)-Markov approximation, are also used to fit the model numerator coefficients.

Electron paramagnetic resonance investigation of the free radicals in the gas and particulate phases of cigarette smoke using spin-trapping techniques

Free radicals in cigarette smoke have been studied using spin trapping EPR techniques. 2R4F reference cigarettes were smoked using 35 ml puff volumes of 2 seconds duration, once every 60 seconds. The particulate phase of the smoke was separated from the gas phase by passing the smoke through a Cambridge filter pad. For both phases, free radicals were measured and identified. A range of spin-traps was employed: PBN, DMPO, DEPMPO, and DPPH-PBN. In the gas-phase, short-lived carbon- and oxygen- centered radicals were identified; the ratios between them changed during the smoking runs. For the first puffs, C-centered radicals predominated while for the later puffs, O-centered radicals were mainly observed. The particulate phase and the ‘tar’ were studied as well.

In vitro fermentation of a red wine extract by human gut microbiota: changes in microbial groups and formation of phenolic metabolites

An in vitro batch culture fermentation experiment was conducted with fecal inocula from three healthy volunteers in the presence and absence of a red wine extract. Changes in main bacterial groups were determined by FISH during a 48 h fermentation period. The catabolism of main flavonoids (i.e., flavan-3-ols and anthocyanins) and the formation of a wide a range of phenolic microbial metabolites were determined by a targeted UPLC-PAD-ESI-TQ MS method. Statistical analysis revealed that catechol/pyrocatechol, as well as 4-hydroxy-5-(phenyl)-valeric, 3- and 4-hydroxyphenylacetic, phenylacetic, phenylpropionic, and benzoic acids, showed the greatest increases in concentration during fermentation, whereas 5-(3′-hydroxyphenyl)-γ-valerolactone, its open form 4-hydroxy-5-(3′-hydroxyphenyl)-valeric acid, and 3,4-dihydroxyphenylacetic acid represented the largest interindividual variations in the catabolism of red wine polyphenols. Despite these changes, microbial catabolism did not produce significant changes in the main bacterial groups detected, although a slight inhibition of the Clostridium histolyticum group was observed.
