Ten-week lifestyle changing program reduces several indicators for metabolic syndrome in overweight adults

We aim to investigate the effectiveness of a 10-week lifestyle intervention focusing on physical activity and high fiber intake for reducing indicators for metabolic syndrome in overweight-obese individuals. A prospective study of 50 overweight (OW) adults (22 in the general educational group - G1; 28 in the high fiber nutrition group - G2) was performed. Both groups were offered dietary counseling and supervised exercise. Clinical, anthropometric, dietary and plasma biochemical tests were performed at baseline - time 0 (T0) and after 10 weeks - time 1 (T1). Both groups improved their dietary quality, but only G2 presented higher intake of fruit and vegetables (servings/day), higher plasma beta-carotene levels and a 24% reduction of MetS incidence. Additionally G2 showed greater reductions in body fat (4%), and waist circumference (7%), obesity class III (2%) and obesity class II (14%) rate. Lifestyle intervention, including a high dietary fiber intake, improved healthy eating index and decreased body fat composition and plasma lipid concentrations leading to MetS incidence reduction.

Evaluation of ten tropical grasses in the northwest region of the state of Sao-Paulo Brazil

The experiment was carried out in the northwest region of the State of São Paulo-Brazil to evaluate ten grasses recently introduced in the region. The grasses studied were: Cynodon nlemfuensis cv. Tifton 68, C dacrylon cv. Tifton 78, Cynodon spp. cv. Tifton 85, C. dactylon cv. Florakirk, C. nlemfuensis cv. Florico, C nlemfuensis cv. Florona, C dactylon cv. Coastcross, Paspalum notation cv. Tifton and NDF (717 to 749 g.kg(-1)) were observed in the Cynodon cultivars while lower values of CP (102 and 107 g.kg(-1)) and NDF (697 and 705 g.kg(-1)) were registered in the cvs. Marandu and Tanzania 1. The contents of ADF were higher in the the cvs. Tanzania 1 and Tifton 9. The average values of IVDMD differed (Ppound0.05) among grasses and were all above 564 g.kg(-1), except for cv. Tifton-9 (499 g.kg(-1)). The results obtained in this work allowed to conclude that the cvs. Tifton 78, Tifton 85, Coastcross, Florona, and Tanzania 1 are interesting options for pastures establishment in the northwest region of the State of São Paulo-Brazil.

Evaluating the karyotypic diversity in species of Hyla (Anura; Hylidae) with 2n=30 chromosomes based on the analysis of ten species

Ten species of Hyla with 2n = 30 from Brazilian fauna were analysed cytogenetically. Hyla minuta is the unique presenting all bi-armed metacentric or submetacentric chromosomes in the karyotype, therefore, with the highest FN = 60. The remaining species have a variable number of uni-armed telocentric or subtelo-centric chromosomes: H. cruzi, H. elianeae, and H. rubicundula with three pairs (FN = 54), H. berthalutzae, H. elegans, H. microps, and H. nana with four pairs (FN = 52), and H. nahdereri and H. sanborni with five pairs (FN = 50). The uni-armed elements are among pairs 5, 6, 7, 11, 14, and 15, which also appeared with metacentric or submetacentric morphology. The remaining chromosome pairs 1, 2, 3, 4, 8, 9,10, 12, and 13 were never found to be telocentric or subtelocentric. AgNOR patterns are species-specific, the majority of the species exhibiting a single pair with AgNORs, with the exception of H. elegans and H. nana with more than one chromosome pair bearing this cytological marker. C banding was obtained in H. berthalutzae, H. cruzi, H. elegans, H. elianeae, H. microps, H. minuta, H. nahdereri, and H. nana, which showed positively stained centromeric heterochromatin. Our analysis confirms the great karyotypic diversity in the species of Hyla with 2n = 30, with no species sharing identical karyotypes.

The development of resistance to caffeine in Drosophila prosaltans: productivity and longevity after ten generations of treatment

The productivity of Drosophila prosaltans treated with six concentrations of caffeine (from 50 mu g/ml to 2,500 mu g/ml of culture medium) during ten generations (similar to 8 months) decreased in a dosage dependent manner in every generation, but at the end of the treatment the flies in all experiments recovered normal productivity, except for those treated with 2,500 mu g/ml. Longevity in the tenth generation was significantly reduced in males and females only in the 2,500 mu g/ml dosage, with males being much more affected than females. In a previous study in which the treatment was done in a single generation, productivity exhibited only a partial recovery when the treatment ceased and longevity was significantly reduced in 1,500 mu g/ml dosages. The hypothesis of selection occurring in ten generations leading to recovery in productivity and to a reduction in the processes which cause a decrease in longevity is being considered.

Ten-dimensional supergravity constraints from the pure spinor formalism for the superstring

It has recently been shown that the ten-dimensional superstring can be quantized using the BRST operator Q = philambda(alpha)d(alpha), where lambda(alpha) is a pure spinor satisfying; lambdagamma(m)lambda = 0 and dalpha is the fermionic supersymmetric derivative. In this paper, the pure spinor version of superstring theory is formulated in a curved supergravity background and it is shown that nilpotency and holomorphicity of the pure spinor BRST operator imply the on-shell superspace constraints of the supergravity background. This is shown to lowest order in alpha' for the heterotic and Type II superstrings, thus providing a compact pure spinor version of the ten-dimensional superspace constraints for N = 1 Type IIA and Type IIB supergravities. Since quantization is straightforward using the pure spinor version of the superstring, it is expected that these methods can also be used to compute higher-order alpha' corrections to the ten-dimensional superspace constraints.

Ten-dimensional super-Yang-Mills with nine off-shell supersymmetries

After adding 7 auxiliary scalars to the d = 10 super-Yang-Mills action, 9 of the 16 supersymmetries close off-shell. In this Letter, these 9 supersymmetry generators are related by dimensional reduction to scalar and vector topological symmetry in N = 2, d = 8 twisted super-Yang-Mills. Furthermore, a gauge-invariant superspace action is constructed for d = 10 super-Yang-Mills where the superfelds depend on 9 anticommuting theta variables. (c) 2007 Published by Elsevier B.V.

Identificação de zonas mortas da cóclea por meio do teste TEN

O audiograma ou o relato do paciente não é suficiente para determinar a presença ou não de zonas mortas na cóclea (ZMC), nem identificar sua extensão. OBJETIVO: Investigar, utilizando o teste TEN, ZMC de indivíduos com perda auditiva neurossensorial (PANS). CEDALVI/ HRAC-USP-Bauru, de agosto de 2003 a fevereiro de 2004. TIPO DE ESTUDO: Estudo de coorte contemporânea com corte transversal. Casuística e Métodos: O TEN foi aplicado nos grupos G1 (5 mulheres com limiares tonais aéreos dentro do padrão de normalidade); G2 (4 mulheres e 5 homens com PANS moderada plana); G3 (19 mulheres e 24 homens com PANS com o grau variando entre leve a profundo). RESULTADOS: Para G1, o valor de TEN para eliminar o tom de teste foi, em média, próximo ao limiar absoluto para todas as freqüências. Não foi observada ZMC em nenhuma das orelhas testadas do G2. Para as 76 orelhas do G3, 6 não apresentaram indício de ZM. CONCLUSÕES: O TEN é efetivo para indicar ZMC em indivíduos com PANS descendente. Há evidência de diferença na detecção do tom puro na presença de ruído entre indivíduos com PANS em altas freqüências e com PANS plana, pois se observou diferença significativa entre o limiar mascarado e absoluto apenas para PANS descendentes e não para as planas.

Dynamics of follicle populations and gonadotropin concentrations in fillies age two to ten months

Follicle populations and concentrations of circulating gonadotropins were studied during age 2-10 months in 10 spring-born pony fillies. Blood sampling and ultrasound scanning were done every 4 days and daily for four 30 day periods. During 5-12 weeks, FSH concentrations were lower in 6 fillies with follicles greater than or equal to 6 mm (mean +/- s.e. 1.4 +/- 0.1 ng/ml) than in 4 fillies with follicles <6 mm (2.8 + 0.3 ng/ml). The diameters and numbers of follicles and gonadotropin concentrations increased progressively during age 2-4 months. A plateau in follicle activity and reduced levels of gonadotropins occurred during 5-7 months. During 8-10 months, follicles grew to >10 mm and gonadotropin concentrations increased. Waves of follicular growth were identified during the 30 day periods by significant increases in the diameter of the 10 largest follicles. The waves did not partition into dominant and subordinate follicles. Results indicated an initial postnatal period of negative ovarian feedback, temporally related changes in gonadotropins and follicles for months 3-10, and development of follicles in waves.

Isolation and characterization of ten microsatellite loci from the Patagonian notothenioid fish Eleginops maclovinus

Eleginops maclovinus, the Patagonian blennie, is a notothenioid (Perciformes) endemic to South American temperate and sub-Antarctic waters. Here, we report ten polymorphic microsatellite loci isolated from a dinucleotide-enriched E. maclovinus genomic library. Among 48 individuals, the number of alleles per locus ranged from eight to 41, and the observed and expected heterozygosity ranged from 0.688 to 0.938 and from 0.695 to 0.968, respectively. No locus significantly deviated from Hardy-Weinberg equilibrium, and no significant linkage disequilibrium between pairs of loci was found. These polymorphic microsatellite loci will be useful for investigating genetic population structure and connectivity among natural populations.

Anti-poverty policies in Brazil: Reviewing the past ten years

This article reviews the main anti-poverty policies implemented in Brazil from the early 1990s to the early 2000s. These include focused and universal policies - such as education and health care - as well as the rural development, a 'middle ground' policy. Though the inter-municipal consortium, a new institutional arrangement gathering municipalities together, has emerged as a promising policy implementation tool, anti-poverty policies have faced implementation difficulties. Lack of coordination between different programs, even within the same policy area, has impaired their effectiveness. As a consequence, compensatory programs, based on monetary transfers to poor families, which face fewer implementation problems, have become the dominant type of anti-poverty policies in Brazil. Despite these shortcomings, a small Brazilian state, Santa Catarina, was able to reduce by 46 percent the number of individuals living in poverty in just ten years. This is a sign that fighting poverty can, after all, be a feasible endeavor. © 2004 IIAS, SAGE Publications (London, Thousand Oaks, CA and New Delhi).
