GRASS UTILIZATION IN GROWING FINISHING BÍSARO PIGS (85-107 KG). PERFORMANCE AND CARCASS COMPOSITION

The use of different quantities of vegetables, forages or fresh grass as fodder for growing-finishing pigs is an important factor of the northern Portugal traditional system. The increasing development of swine production in outdoor systems, extensive and organic production, turns to upcoming natural diets, in which grass performs a significant part. With regard to this, some investigation has been made concerning the use of fibre-rich feed ingredients in pig nutrition. Metabolic effects of its ingestion are analysed concerning different sights (economical, social, environmental and physiological ones). The aim of this work was to study the effects of grass utilization in the diets on performances of finishing Bísaro pigs. A total of 22 pigs (16 castrated males and 6 females) was housed outdoor and fed ad libitum (37 – 85 kg live weight) with a growing diet and then transferred to an indoor system (with free access to an outdoor area) for 49 days, according to 3 different treatments: 100% concentrate (C), 75% concentrate + ad libitum grass (CE75), 50% concentrate + ad libitum grass (CE50). The grass was supplied and its intake registered on a daily basis. Every 14 days, the pigs were weighted and their back fat (P2 in vivo) measured. After slaughter (average weight of 107 kg LW), yield and ½ left carcass characteristics were controlled. During the outdoor growing phase, the ADG was 513 g/day. During the indoor finishing phase, the increase grass intake was proportional to the reduction of concentrate in the diet. The ADG (g) and the fat deposition (P2 cm) were significantly different (P<0,05) in the 3 treatments (ADG: C=641, CE75=467, CE50=356 and: C=11,4, CE75=+9,5, CE50=+6,2). The empty body weight (kg) was also proportional to the intake of concentrate (C=116,2; CE75=107,7; CE50=102,2). Comparatively to the weight of the body parts, pigs that had higher intake of grass and lower of concentrate showed a higher % of shoulder (P<0,05; C=20,4, CE75=21,7, CE50=22,2) and the pH45min of CE carcasses was significantly higher (P<0,05). As a conclusion, concentrate substitution for grass showed a slower growing rate, thinner carcasses and a high technological quality. Neverthelles variability (CV %) of the productive parameters at the end of this study were higher in the treatments that included grass: live weight (C= 10,5%; C75=10,7%; C50=14,3%), finishing ADG (C=24%; C75=37%, C50=42%), and final fat (C=37%; C75=32%, C50=52%). These values suggest that the utilization of fibrous feeds in growing-finishing swine may be one of the possible explanations of the more heterogeneous products and carcasses found in the traditional or extensive systems, common users of fibrous feeds in the carcass finishing phase

Unilateral progressive osseous heteroplasia

A 50-year-old male patient presented with firm subcutaneous nodules and plaques with a gritty texture, unilaterally affecting the left side of the trunk and the left limbs. These lesions had had a progressive course since early childhood and caused functional impairment. There was no family history of similar disorders. No phospho-calcium metabolism abnormalities were observed. Biopsies of the affected areas demonstrated osteoma cutis. Analysis of DNA showed no mutation of the GNAS gene. The clinical features were consistent with progressive osseous heteroplasia, atypically presented in a unilateral form, probably revealing a mosaic distribution

Modelagem da hidrografia em planos de manejo e critérios para definição de árvores em APP pelo Modeflora.

Novas tecnologias, sendo advindas do geoprocessamento e do sensoriamento remoto, vêm sendo desenvolvidas a fim de auxiliar no processo de delimitação das APPs e demarcação das árvores. No entanto, faltam estudos para investigar e comprovar sua eficácia. Não há registro de trabalhos, publicados no Brasil, que utilizem diferentes metodologias na definição de APPs para avaliá-las. O presente trabalho teve como objetivo propor uma metodologia precisa para o mapeamento de áreas de preservação permanente e definição de árvores protegidas e exploráveis na região de influência das APPs, comprovando a sua aplicabilidade nos PMFS.bitstream/CPAF-AC-2010/23132/1/circtec-n50.pd

Paraneoplastic pemphigus with clinical features of lichen planus associated with low-grade B cell lymphoma

BACKGROUND: Neoplasia-induced lichen planus is described as a cell-mediated reaction to unknown epithelial antigens. Paraneoplastic pemphigus (PNP), characterized by the presence of a specific array of autoantibodies, probably represents a different form of presentation of the same autoimmune syndrome where the mucocutaneous expression depends on the dominant pathologic mechanism. METHODS: The authors report a case of PNP with predominant lichen planus-like lesions and review the relevant literature. We observed a 74-year-old female with vesico-bullous, erosive, target-shaped and flat papular lichenoid lesions on the lower legs, palms and soles, evolving for 3 weeks. Histopathology revealed a lichenoid dermatitis. Direct immunofluorescence showed C3 deposition around keratinocytes and epidermal IgG intranuclear deposition. Indirect immunofluorescence revealed circulating IgG with intercellular staining on rat bladder substrate. Immunoblotting demonstrated bands of 130, 190, 210 and 250 kDa antigens. A pararenal B cell lymphoma was found. RESULTS: Oral corticotherapy with 40 mg prednisolone daily was initiated with a good cutaneous response. Four months later, cyclophosphamide (50 mg/day) was introduced because of a discrete enlargement of the pararenal mass. The patient died on the seventh month of follow up as a result of respiratory insufficiency. CONCLUSION: PNP has different forms of presentation and the lack of a consensus about diagnostic criteria may contribute to underdiagnosed cases. Advances on the knowledge of the sensitivity and specificity of diagnostic criteria have allowed a better accuracy of diagnosis

Fundamentos cristolquímicos de la sistemática general de los sulfuros y sulfosales metálicos

Se revisan las principales tendencias que han orientado las clasificaciones que hasta el momento han sido propuestas para 10s sulfuros y las sulfosales. Se exvonen 10s fundamentos cristaloauimicos para un esquema de clasificación de base estructural que tiene en cuenta 10s aspectos particulares del enlace quimico en estos compuestos. Se utiliza la definición de tip0 estructural expuesta en la sistematica general de las estructuras inorganicas (Lima de Faria y Figueiredo 1976) y las propuestas surgeridas para la reformulación del sistema clasificatorio (Figueiredo 1984). Se clasifican 10s tipos de acuerdo con la multiplicidad de las unidades estructurales: monoatómicas, en configuraciones de empaquetamiento aniónico y atómicas (subdivididas en poliméricas, policatiónicas y polianiónicas) y en las demh configuraciones estructurales. Estas se agrupan en cuatro Órdenes, de acuerdo con el grado de dimensionalidad de aquellas unidades: O-D, aniones aislados o grupos finitos de poliedros de coordinación, de cationes interligados o de aniones interligados; I-D, cadenas; 2-D, capas; 3-D, reticulos tridimensionales.After reviewing the trends in previous systematics of sulphides and sulphosalts, the fundamentals of a crystallochernical classification scheme are presented, taking into account the nature of the chemical bonding. The definition of structure type by Lima de Faria & Figueiredo (1976) and further proposals by Figueiredo (1984) for improvement of the general classification scheme are adopted. Structure types are classified according to the rank of the structural units -manoatomic in packing configurations and multiatomic in other arrangements, subdivided into polymeric, polycationic and polyanionic- and grouped into four orders depending on the dimensionality of those units: O-D, for isolated or finite groups, either of coordination polyhedra or of interlinked cations or anions; 1-D, chains; 2-D, sheets; 3-D, frameworks. The implementation of a structural data bank for sulphides and sulphosalts is reported

Caqui cv. 'Mikado': análise de compostos voláteis em frutos adstringentes e destanizados.

O objetivo do presente trabalho foi determinar os compostos voláteis em frutos de caqui Mikado adstringentes e destanizados, em dois períodos de armazenamento, utilizando microextração em fase sólida (MEFS, fibra DVB/CAR/PDMS) por cromatografia gasosa acoplada à espectrometria de massas (CG-EM). A partir dos resultados foi possível observar diferenças na composição volátil em frutos adstringentes e destanizados de caqui Mikado, com perdas em ambas as amostras. A remoção da adstringência com exposição ao álcool promoveu aumento dos voláteis no 1o dia após a destanização. Os compostos voláteis de caqui Mikado são representados, majoritariamente, por hidrocarbonetos terpênicos, seguidos de ésteres de cadeia linear
