Aging is related to a decrease in physiological abilities, especially cognitive functions. To unravel further evidence of age-related cognitive decline, we analyzed which physical and functional variables are predictors of cognitive performance in a sample of 498 Brazilian elderly (67.26% women). To do so, we used the Stroop test as a tool to evaluate executive functions and the General functional fitness index (GFFI) to evaluate the functional fitness of the participants. A linear regression analysis revealed that female sex (β=-0.097; t=-2.286; P=0.023), younger age (β=0.205; t=4.606; P<0.0001), more years of education (β=-0.280; t=-6.358; P<0.0001), and higher GFFI (β=-0.101; t=-2.347; P<0.02) were predictors of better cognitive performance. Body mass index (kg/m2) and nutritional status (underweight, eutrophic, overweight, or obese) were not predictors of cognitive performance. Interestingly, among the GFFI tasks, muscle strength influenced the test execution time, both in upper and lower limbs (elbow flexion: β=-0.201; t=-4.672; P<0.0001; sit-to-stand: β=-0.125; t=-2.580; P<0.01). Our findings showed that: 1) women performed the Stroop test faster than men; 2) the older the person, the lower was the cognitive performance; 3) the higher the education, the better the test execution time; and 4) higher scores in the GFFI were associated with a better performance in the Stroop test. Therefore, gender, age, education, and functional fitness and capacity were predictors of cognitive performance in the elderly.

Resumen: El manejo de la defoliación es determinante de la estructura del dosel forrajero y afecta la acumulación de forraje y su valor nutricional. El objetivo de este trabajo fue determinar la acumulación de forraje, su composición morfológica y el valor nutritivo de inia Sepé sometido a la combinación de tres frecuencias (defoliación a 90 %, 95 % y máxima interceptación de luz por el dosel forrajero durante el rebrote -il90%, il95% e ilmáx) y dos severidades de defoliación (40 y 60 % de la altura precorte). El experimento fue realizado desde el 15 de noviembre de 2018 hasta el 31 de marzo de 2019 en Tacuarembó. Fueron realizadas evaluaciones de IL y altura del dosel forrajero, masa de forraje, composición morfológica y valor nutritivo del forraje. La masa de forraje fue mayor en Feb-Mar. El porcentaje de hojas fue mayor para la mayor frecuencia de defoliación (il90%). El porcentaje de tallos no varió entre tratamientos (promedio de 23 %). El porcentaje de material muerto fue mayor para la menor frecuencia (ilmáx) y para la severidad 40 %. Mayores valores de fda, fdn y menor digestibilidad fueron registrados para la combinación ilmáx/40 %. Para il90% mayor fda y fdn y menor digestibilidad fueron registrados para la severidad 60 % (Feb-Mar). La acumulación de forraje fue mayor para il90% e il95%. inia Sepé posee gran flexibilidad de manejo, mientras que la meta precorte óptima no debe exceder 95 % de il (30 cm de altura), como forma de asegurar producción de forraje con elevado valor nutritivo y elevada eficiencia de cosecha.

Abstract: Defoliation strategies determine sward canopy structure and affect forage accumulation and nutritive value. The objective of this study was to determine forage accumulation, morphological composition and nutritive value of inia Sepé subjected to combinations of three frequencies (defoliation at 90%, 95% and maximum canopy light interception during regrowth -li90%, li95% and liMax), and two severities of defoliation (40 and 60% of the pre-cutting height). The experiment was carried out from November 15th, 2018 to March 31st, 2019 in Tacuarembó. Measurements of li and canopy height, forage mass morphological composition and nutritional value were carried out. Forage mass was greater in Feb-March. The percentage of leaves was greater for the higher defoliation frequency treatment (li90%). The percentage of stems did not vary among treatments (average of 23%). The percentage of dead material was greater for the lower defoliation frequency treatment (liMax) and 40% defoliation severity. Greater adf and ndf values and smaller digestibility were recorded for liMax/40% combination. For li90%, greater adf and ndf, and smaller digestibility were recorded for the 60% defoliation severity (Feb-March). Forage accumulation was greater for li90% and li95%. inia Sepé shows large flexibility to defoliation management, and the optimal pre-cutting target should not exceed li95% (i.e. 30 cm of canopy height) in order to ensure production of high nutritive value forage and harvest efficiency.

The prevalence of gender and age related pattern of the different types of prosthetic restorations are important variables to be estimated. The aim of this study was to evaluate the profile of age and gender in patients rehabilitated with dental prostheses on School of Dentistry during five years. Were evaluated 638 records of patients who received fixed prosthesis (FP), removable partial (RP) or total dentures (T). Rehabilitated patients with RP had their prostheses classified into dental-mucous-supported (DM) or tooth-supported (D). To analyze the results, patients were divided into 2 groups: A) >50 years or B) <50 years. Data were statistically analyzed by Fisher's exact test or chi Square (p<0.05). No statistical significance relation to age and types of prostheses was observed. On RP, 47% was D and 53% DM, there was no statistically significant difference. It was possible to conclude that the rehabilitation of greater number of the teeth increases with age and is prevalent in all periods of adulthood, especially in women.

La prevalencia de sexo y el padrón de edad relacionado a los diferentes tipos de rehabilitaciones protésicas son variables importantes que deben ser estudiadas. De esta manera, el objetivo de este estudio fue evaluar el perfil de edad y género en pacientes rehabilitados con prótesis dentales en un curso de Odontología durante un periodo de cinco años. Fueron evaluados 638 fichas de pacientes que recibieron prótesis parcial fija (PPF), prótesis parcial removible (PPR) y prótesis total (PT). Las prótesis de los pacientes rehabilitados con PPR fueron clasificadas en dentomucosoportada (DM) o dentosoportadas (D). Para el análisis de los resultados, los pacientes fueron divididos en 2 grupos: A) >50 años y B) <50 años. Los datos fueron analizados estadísticamente por el test exacto de Fisher o chi-cuadrado (p<0,05). No se observaron diferencias significativas en relación a la edad y tipo de prótesis. Para la PPF 74% fueron <50 años, para la PPR 52%, >50 años y para la PT 92%, >50 años. En todas las prótesis, existió una mayor prevalencia del género femenino. Con relación a la clasificación de las PPRs, 47% fueron D y 53% DM, sin identificar diferencias estadísticamente significativas. De esta manera se puede concluir que la necesidad de rehabilitación de un mayor numero de elementos dentales aumenta con la edad, siendo prevalente en todos los periodos de la vida adulta, principalmente, en mujeres.

The present study evaluated electrocardiographic alterations in rats with epilepsy submitted to an acute myocardial infarction (AMI) model induced by cardiac ischemia and reperfusion. Rats were randomly divided into two groups: control (n=12) and epilepsy (n=14). It was found that rats with epilepsy presented a significant reduction in atrioventricular block incidence following the ischemia and reperfusion procedure. In addition, significant alterations were observed in electrocardiogram intervals during the stabilization, ischemia, and reperfusion periods of rats with epilepsy compared to control rats. It was noted that rats with epilepsy presented a significant increase in the QRS interval during the stabilization period in relation to control rats (P<0.01). During the ischemia period, there was an increase in the QRS interval (P<0.05) and a reduction in the P wave and QT intervals (P<0.05 for both) in rats with epilepsy compared to control rats. During the reperfusion period, a significant reduction in the QT interval (P<0.01) was verified in the epilepsy group in relation to the control group. Our results indicate that rats submitted to an epilepsy model induced by pilocarpine presented electrical conductivity alterations of cardiac tissue, mainly during an AMI episode.

This paper reports on measurements of the resistive transition in polycrystalline Gd1-χ Ceχ Ba2 Cu3 O7-δ samples (x = 0.000, 0.025 and 0.050). The samples were produced by a standard solid state reaction method and in two different thermal routes. The microstructure was analyzed by X-ray diffraction. The samples were considered homogeneous since no extra peaks due to impurity phase were observed. To identify power-law divergences in conductivity, the results were analyzed in terms of the temperature derivative of the resistivity and the logarithmic temperature derivative of the conductivity (d ln (Δσ) /dT). From the results, the occurrence of a two-stage transition besides the pairing transition splitting for sample with x = 0.050 was observed. Such splitting was associated with Ce doping and related with the occurrence of a phase separation. In the normal phase, Gaussian and critical fluctuations conductivity regimes were identified. Ón approaching the zero resistance state, our results showed a power-law behavior that corresponds to a phase transition from a paracoherent to a coherent state of the granular array.

The present paper describes a novelty approach to detect structural changes in the generating units of Itaipu power plant. The methodology is based solely on output time series measured in the rotating electric machine. The method deals with the application of time-series analysis through auto-regressive moving average models (ARMA) and statistical modeling for the linear prediction of damage diagnosis. In order to illustrate the procedure proposed is employed a simplified mathematical model regarding shaft radial vibrations in the generating unit 18A of Itaipu power plant. Several parameters variations are imposed in the system to simulate real damages conditions in the electrical machine. The approach is also evaluated with experimental data. The efficacy, advantages and drawbacks of the proposed method are demonstrated through these numerical and experimental tests.

The aim of this work was to evaluate the role of nutrition and shearing during last third of pregnancy, on the energetic metabolism of ewes and the energetic storage of their lambs at parturition. 38 Corriedale ewes carrying single fetus were randomly divided in two groups at 90 days of pregnancy, R (n = 12, supplemented with ruminant concentrate) and CN (n = 26, fed on natural pastures). The energetic status of the ewes was evaluated using glicaemia and seric levels of ß-hidroxybutyrate. When reaching 110 days of gestation, half of the ewes in CN group were shorn (E). Newborn lambs were blooded to study glicaemia levels at parturition and 24 h afterwards, weighed at birth and after 24, 48 and 72 h, and total weight and energetic value of their perirenal brown fat was measured. Ewes in groups R and E presented glicaemia levels higher than those in CN in the days before at parturition, whereas hydroxybutyrate was more elevated in groups CN and E than in group R. The weight of ewe-lambs at birth did not differ between groups, but by this time glicaemia levels were higher in group R than in CN. Glicaemia was also higher in lambs of both groups R and E by 24 h after birth. Perirenal brown fat in group E had highter caloric value compared to CN, which suggests a relationship between the energetic status and management of ewes at parturition and the energetic storage of their lambs at birth.

El objetivo fue evaluar los efectos de la alimentación y el esquileo, durante el último tercio de la gestación, sobre el metabolismo energético de las ovejas y su repercusión sobre las reservas energéticas de sus corderos. A los 90 días de gestación 38 ovejas Corriedale adultas, gestando un solo feto, fueron divididas en dos grupos, R (n = 12, suplementado con concentrado) y CN (n = 26, alimentado a campo natural), evaluándose su estado metabólico mediante determinaciones de la glucemia y del ß-hidroxibutirato. A los 110 días de gestación se esquiló a la mitad de las ovejas del grupo CN, quedando dividido en dos nuevos grupos (E, esquiladas, n = 13 y campo natural, CN, n = 13), estudiándose el efecto de la esquileo sobre los mismos parámetros. En los corderos se determinó la glucemia (al parto y a las 24 horas), el peso (al parto, a las 24, 48 y 72 horas) y el peso y valor energético de grasa parda perirrenal. En el día 140 de gestación las ovejas alimentadas con concentrado y las esquiladas presentaron valores superiores de glucemia que las alimentadas exclusivamente con pasto natural; los valores de ß-hidroxibutirato sérico fueron más elevados en las ovejas de pasto natural y las esquiladas que las suplementadas con concentrado. Al nacimiento el peso de los corderos no presentó diferencias entre los tres grupos. La glucemia de los corderos nacidos de ovejas suplementadas con concentrado fue mayor que los de ovejas de pasto natural, al parto y a las 24 horas y en las esquiladas mayor en que se alimentaban exclusivamente de pasto a las 24 horas. Los corderos de las ovejas esquiladas presentaron grasa parda con mayor valor energético que los provenientes de ovejas que pastaban exclusivamente hierba, demostrándose así relación entre el estado energético de las ovejas al parto y las reservas energéticas con las que nacen sus corderos.

The results showed that the approach is suitable for practical applications.

Kaposi's sarcoma (KS) became a critical health issue with the emergence of acquired immunodeficiency syndrome (AIDS) in the 1980s. Four clinical-epidemiological forms of KS have been described: classical KS, endemic KS, iatrogenic KS, and AIDS-associated KS. In 1994, Kaposi's sarcoma-associated herpesvirus (KSHV) or human herpesvirus type 8 was identified by Chang and colleagues, and has been detected worldwide at frequencies ranging from 80 to 100%. The aim of the present study was to evaluate the frequency of KSHV infection in KS lesions from HIV-positive and HIV-negative patients in Brazil, as well as to review the current knowledge about KS transmission and detection. For these purposes, DNA from 51 cases of KS was assessed by PCR: 20 (39.2%) cases of classical KS, 29 (56.9%) of AIDS-associated KS and 2 (3.9%) of iatrogenic KS. Most patients were males (7.5:1, M/F), and mean age was 47.9 years (SD = ± 18.7 years). As expected, HIV-positive KS patients were younger than patients with classical KS. On the other hand, patients with AIDS-associated KS have early lesions (patch and plaque) compared to classical KS patients (predominantly nodular lesions). This is assumed to be the result of the early diagnose of KS in the HIV-positive setting. KSHV infection was detected by PCR in almost all cases (48/51; 94.1%), irrespectively of the clinical-epidemiological form of KS. These results show that KSHV is associated with all forms of KS in Brazilian patients, a fact that supports the role of this virus in KS pathogenesis.

O objetivo do presente trabalho foi avaliar o parasitismo do nematóide Deladenus siricidicola,Bedding (Neotylenchidae)em adultos de Sirex noctilio, Fabricius, 1793 (Hymenoptera: Siricidae).
