The Association between Skipping Breakfast and Biochemical Variables in Sedentary Obese Children and Adolescents

Objective To investigate the relationship between skipping meals and biochemical variables in obese children and adolescents.Study design The sample was composed of 174 obese children and adolescents, aged between 6 and 16 years (80 male and 94 female). Body composition was assessed by dual-energy x-ray absorptiometry, fasting blood glucose, and lipid profile were measured after 12 hours fasting. The frequency of skipping breakfast, lunch, or dinner was assessed through a face-to-face interview carried out with the parents.Results The prevalence of eating breakfast daily was low in boys (47.5%) and girls (44.7%). A higher frequency of eating breakfast was negatively correlated with glucose (r = -0.16; P = .026), triglycerides (r = -0.19; P = .011), and very low density lipoprotein cholesterol (r = -0.21; P = .005). In the multivariate model, the weekly frequency of eating breakfast remained negatively associated with glucose (beta = -0.975; P = .017), triglycerides (beta = -7.792; P = .017), and very low density lipoprotein cholesterol (beta = -1.870; P = .009) independent of age, sex, trunk fatness, and parents' education.Conclusion Skipping meals, mainly breakfast, is associated with glucose and lipid levels in obese children and adolescents.

Unconstrained variables of non-commutative open strings

The boundary conditions of the bosonic string theory in non-zero B-field background are equivalent to the second class constraints of a discretized version of the theory. By projecting the original canonical coordinates onto the constraint surface we derive a set of coordinates of string that are unconstrained. These coordinates represent a natural framework for the quantization of the theory.

Behavior of cardiac variables in animals exposed to cigarette smoke

OBJECTIVE: To assess the behavior of cardiac variables in animals exposed to cigarette smoke. METHODS: Two groups of Wistar rats were studied as follows: control group (C), comprising 28 animals; and smoking group (S), comprising 23 animals exposed to cigarette smoke for 30 days. Left ventricular cardiac function was assessed in vivo with transthoracic echocardiography, and myocardial performance was analyzed in vitro in preparations of isolated left ventricular papillary muscle. The cardiac muscle was assessed in isometric contractions with an extracellular calcium concentration of 2.5 mmol/L. RESULTS: No statistical difference was observed in the values of the body variables of the rats and in the mechanical data obtained from the papillary muscle between the control and smoking groups. The values of left ventricular systolic diameter were significantly greater in the smoking animals than in the control animals (C= 3.39 ± 0.4 mm and S= 3.71 ± 0.51 mm, P=0.02). A significant reduction was observed in systolic shortening fraction (C= 56.7 ± 4.2% and S= 53.5 ± 5.3%, P=0.02) and in ejection fraction (C= 0.92 ± 0.02 and S= 0.89 ± 0.04, P=0.01). CONCLUSION: The rats exposed to cigarette smoke had a reduction in left ventricular systolic function, although their myocardial function was preserved.

Genetic divergence among Psidium accessions based on biochemical and agronomic variables

Sessenta e nove acessos de Psidium, coletados em seis estados brasileiros, foram analisados para dois métodos não hierárquicos de agrupamento e por componentes principais (CP), visando orientar programas de melhoramento. Foram analisadas as variáveis ácido ascórbico, β-caroteno, licopeno, fenóis totais, flavonóides totais, atividade antioxidante, acidez titulável, sólidos solúveis, açúcares solúveis totais, teor de umidade, diâmetro lateral e transversal do fruto, peso da polpa e das sementes/fruto, número e produção de frutos/planta. Foram observados agrupamentos específicos para os acessos de araçazeiros no método de Tocher e do k-means e na dispersão tridimensional dos quatro CPs. Os acessos de araçazeiros foram separados dos de goiabeira. Não foi observado nenhum agrupamento específico por estado de coleta, indicando a inexistência de barreiras na propagação dos acessos de goiabeira. As análises sugerem a prospecção de maior número de amostras de germoplasma num menor número de regiões, bem como acessos divergentes com alto teor de compostos nutricionais.

Fisiologia, concepções médicas e o estatuto da medicina em Descartes

Notre intention est montrer comment les conceptions médicales de Descartes, disséminées dans ses oeuvres et dans sa correspondance, se sont constituées a partir de deux questions fondamentales posées par le philosophe: 1 - comment fonctionne-t-il notre organisme; 2 - quel est-t-il la nature du corps animal et, en particulier, du corps humain.
