Abstract: O objetivo deste trabalho foi identificar genótipos, superiores em produtividade, adaptabilidade e estabilidade, na produ o de gr os de feijoeiro, por meio da análise Lin & Binns (1988), modificada por Carneiro (1998). Foram avaliados vinte e dois genótipos pertencentes aos principais programas de melhoramento do país. Essas avalia es constaram de dados dos ensaios de VCU 2007/2008/2009 para o Estado de S o Paulo, que seguiram as normas estabelecidas pelo MAPA/SNPC, para ensaios de campo. Estes ensaios foram instalados em vinte e quatro ambientes, nas épocas das águas de 2007 e 2008, seca de 2008 e 2009 e inverno de 2008 e 2009. Os resultados obtidos no conjunto dos anos e ambientes de 2007/2008/2009 demonstraram que os genótipos 'Gen C2-1-3', 'CNFC 10408', 'Juriti Claro' e 'LP 04-72' comportaram-se como os mais estáveis e adaptados. O método Lin & Binns (1988), modificado por Carneiro (1998), mostrou-se adequado para análise dos dados, identificando os genótipos mais estáveis, produtivos e adaptados aos ambientes de cultivo. The objective of the present study was to identify superior genotypes for yield, adaptability and stability in common bean yield using the Lin & Binns (1988) analysis modified by Carneiro (1998). Twenty-two genotypes were analyzed from the main Brazilian plant breeding programs. The assessments consisted of data from the VCU 2007/2008/2009 experiments for S o Paulo State that followed the norms established by the MAPA/SNPC for field trials. The experiments were set up in twenty-four environments, in the 2007 and 2008 wet growing seasons, the 2008 and 2009 dry growing seasons, and 2008 and 2009 winter growing seasons. The results obtained in the set of years and environments of 2007/2008/2009 showed that the genotypes 'Gen C2-1-3', 'CNFC 10408', 'Juriti Claro' and 'LP 04-72' performed with the greatest stability. The Lin & Binns (1988) analysis modified by Carneiro (1998) was shown to be suitable to analyze the data, identifying the most stable and productive genotypes adapted to the cropping environments.

Abstract: Localized scleroderma is a rare disease, characterized by sclerotic lesions. A variety of presentations have been described, with different clinical characteristics and specific prognosis. In scleroderma en coup de sabre (LScs) the atrophic lesion in frontoparietal area is the disease hallmark. Skin and subcutaneous are the mainly affected tissues, but case reports of muscle, cartilage, and bone involvement are frequent. These cases pose a difficult differential diagnosis with Parry-Romberg syndrome. Once considered an exclusive cutaneous disorder, the neurologic involvement present in LScs has been described in several case reports. Seizures are most frequently observed, but focal neurologic deficits, movement disorders, trigeminal neuralgia, and mimics of hemiplegic migraines have been reported. Computed tomography and magnetic resonance imaging have aided the characterization of central nervous system lesions, and cerebral angiograms have pointed to vasculitis as a part of disease pathogenesis. In this paper we describe the clinical and radiologic aspects of neurologic involvement in LScs. 1. Introduction Scleroderma is a rare disease of unknown etiology, characterized by thickening and hardening of skin resulting from increased collagen production. The term includes a variety of diseases, from localized scleroderma (LS) to systemic sclerosis. LS is traditionally considered to be limited to skin, subcutaneous tissue, underlying bone, and, in craniofacial subtype, nervous system involvement [1]. Recent studies, however, have described malaise, fatigue, arthralgia, and myalgia in morphea. Moreover, rheumatologic, ophthalmologic and neurologic symptoms and signs have been described in up to 20% of the patients with LS. Based on these findings LS ought to be differentiated from systemic sclerosis by the absence of sclerodactylya, Raynaud’s phenomenon, and capillaroscopic abnormalities [1]. LS incidence ranges from 0.4 to 2.7 per 100,000 people [2]. Although present in all races, the prevalence among Caucasians is increased, summing up 72 to 82% of the patients [2]. Females are primarily affected [1], and a similar distribution between children and adults occurs [1, 3]. Disease incidence peaks in the fifth decade of life in adults, whereas 90% of children are diagnosed between 2 and 14 years of age [1, 3–5]. Linear scleroderma en coup de sabre (LCsc) is a rare subset of LS. The typical presentation affects frontoparietal region, and the mean age of onset is around 13 years old [1]. In this paper, clinical presentation of LScs and its neurological

Abstract: this paper analyzes the relationship between the old age and illiteracy in the northeastern of brazil, especially in two areas: the semi-arid region of rio grande do norte and the area of southern bahia cocoa. according to the ibge 2010 census, in the northeast there are higher rates of illiteracy in the country. the problem of illiteracy affects mainly older people, black and brown, female and living in rural areas. the relationship between landowners and illiteracy partly explains the higher incidence of this problem in the northeast, where there is greater concentration of income and also the rural property. the absence in brazil of education policies directed towards old age and illiteracy can be observed in the absence specific laws, such as brazilian law of education and the old age and statutes of the elderly. finally, the understanding of this issue from the perspective of sociology is a theoretical contribution relevant to educational studies.

Revista Ibero-Americana de Estratégia , 2007, DOI: 10.5585/riae.v2i1.22
Abstract: This paper deals with the elements of ageism that exist in the enterprise strategies and labors recruiting. The age limits demanded by the profile of offices that will be filled and the exclusion elements that exist in the new productive paradigms represent a clear discrimination against older workers. In this article we propose a study about such elements and prove that the age limits affects the principle of equity supported on opportunities equality. Based in job’s announcements with age limits, in specific bibliography about unemployment and exclusion in the work, and statistical data about the age reduction in the management positions. Este artigo analisa os elementos de exclus o por idade presentes nas estratégias empresariais e nos processos de sele o profissional. Procuramos demonstrar que os limites de idade que integram o perfil dos cargos a serem preenchidos e os elementos de exclus o presentes nos novos paradigmas produtivos representam uma clara discrimina o contra os trabalhadores mais velhos. Neste trabalho, propomos um estudo sobre tais elementos, no intento de demonstrar que os limites de idade ferem o princípio da eqüidade, apoiado na igualdade de oportunidades, com base em anúncios de emprego contendo limites de idade, em bibliografia específica sobre desemprego e exclus o no trabalho, e em dados estatísticos sobre a queda da faixa de idade nos cargos de gerência.

Abstract: this study was thought to characterized clinical and laboratory findings of a narcoleptic patients in an out patients unit at s?o paulo, brazil. method: 28 patients underwent polysomnographic recordings (psg) and multiple sleep latency test (mslt) were analyzed according to standard criteria. the analysis of hladqb1*0602 allele was performed by pcr. the hypocretin-1 in cerebral spinal fluid (csf) was measured using radioimmunoassay. patients were divided in two groups according hypocretin-1 level: normal (n) - hypocretin-1 higher than 110pg/ml and lower (l) hypocretin-1 lower than 110 pg/ml. results: only 4 patients of the n group had cataplexy when compared with 14 members of the l group (p=0.0002). discussion: this results were comparable with other authors, confirming the utility of using specific biomarkers (hla-dqb1*0602 allele and hypocretin-1 csf level) in narcolepsy with cataplexy. however, the hladqb1*0602 allele and hypocretin-1 level are insufficient to diagnose of narcolepsy without cataplexy.

Abstract: purpose: to evaluate the expression of erbb-2 and of the estrogen and progesterone (er/p) hormonal receptors in the transition regions between the in situ and the invasive fractions of ductal breast neoplasia (isdc and idc, respectively). methods: eighty-five cases of breast neoplasia, containing contiguous isdc and idc areas, were selected. histological specimens from the isdc and the idc areas were obtained through the tissue microarray (tma) technique. the erbb-2 and the er/pr expressions were evaluated through conventional immunohistochemistry. the mcnemar's test was used for the comparative analysis of the expressions of erbb-2 protein and the er/pr in the in situ and invasive regions of the tumors. the confidence intervals were set to 5% (p=0.05). intraclass correlation coefficients (icc) were calculated to assess the cross-tabulation agreement of the erbb-2 and the er/pr expression in the isdc and the idc areas. results: the erbb-2 expression has not differed between the isdc and the idc areas (p=0.38). comparing the two areas in each case, there was agreement in the expression of erbb-2 (icc=0.64), pr (icc=0.71) and er (icc=0.64). restricting the analysis to tumors with the in situ component harboring necrosis (comedo), the icc for erbb-2 was 0.4, compared to 0.6 for the whole sample. in this select group, the icc for pr/er did not differ substantially from those obtained with the complete dataset: as for the er, icc=0.7 (versus 0.7 for the entire sample) and for pr, icc=0.7 (versus 0.6 for the entire sample). conclusions: our findings suggest that the erbb-2 and the er/pr expressions do not differ in the contiguous in situ and invasive components of breast ductal tumors.

Abstract: despite a natural history interest in the early 1900s, relatively little ecological research has been carried out in the rio purús basin of central amazonia, brazil. here we describe a new study area in the region of lago uaua?ú with an emphasis on the climate, forest structure and composition, and soil characteristics between adjacent unflooded (terra firme) and seasonally inundated forests; situated within both the white-water (várzea) and black-water (igapó) drainage systems that dominate the landscape. the climate was found to be typical of that of the central amazon. várzea forest soils had high concentrations of nutrients, while terra firme and igapó soils were comparatively nutrient-poor. terra firme forests were the most floristically diverse forest type, whereas várzea was intermediate, and igapó the most species-poor. the lecythidaceae was the most important family in terra firme while the euphorbiaceae was the most important in both várzea and igapó. there were significant differences between forest types in terms of number of saplings, canopy cover and understorey density. in contrasting our results with other published information, we conclude that the lago uaua?ú region consists of a typical central amazonian forest macro-mosaic, but is a unique area with high conservation value due to the intimate juxtaposition of terra firme, várzea and igapó forests.
