Abstract: a case of torsion of the gallbladder is presented. this is a rare condition that occurs when it is associated with anatomical variants related to abnormal fixation of the gallbladder to the liver bed. the blood irrigation is insufficient and the gallbladder develops necrosis. the abnormal implantation occurs in 4% of the population. if the gallbladder losses its fixations to the inferior margin of the liver with the presence of a 1011.g mesocyst a torsion can occur when this gallbladder twists axially with subsequent occlusion of the blood flow. the signs and symptoms are similar to those of severe acute cholecystitis: abrupt onset of the pain and large palpable mass below the right costal margin. the ultrasound can show a very large and anteriorly floating gallbladder: in this case, the ultrasound did not show any abnormal signs, so it is usually diagnosed at laparotomy and the treatement consists of cholecystectomy. this condition should be suspected in acute abdominal pain of unknown origin.

Abstract: The effects of slaughter weight (28, 32, 36, and 40 kg) on musclecomposition and fatty acid profile were determined in an experiment using samples of the Longissimus dorsi (LD) of 20 ram lamb ( Bergamacia and Corriedale). Mean weight was 12.1 ± 1.05 kg at the beginning. Lambs were fed with a mixture of 30% corn silage, 35% soybean meal, 34% oat hay, and 1% vitamins and minerals, ad libitum. Samples of Longissimus dorsi muscle were analyzed for their content in moisture, ash, crude protein, total lipids, and fatty acid profile. Oleic acid (18:1n-9) was in greater concentration than other fatty acids in all samples investigated. The concentration of saturated fatty acids (SFA) increased (p < 0.05) with an increase in slaughter weight, while monounsaturated and polyunsaturated fatty acids (PUFA) decreased. Lambs slaughtered at either 28 or 36 kg hadan n-6/n-3 ratio (2.9 and 2.85, respectively) close to the recommended for humans (4.0 maximum). The overall results showed that slaughtering lamb at 28 kg resulted in the best meat quality as shown by nutritional indexes for humans (PUFA/SFA and n-6/n-3 ratios) and concentrations of crude protein (16.02%) and total lipids (13.24%). Os efeitos do peso de abate (28, 32, 36 e 40 kg) sobre a composi o centesimal e perfil de ácidos graxos foram determinados em um experimento com amostras do músculo Longissimus dorsi (LD), de 20 cordeiros ( Bergamácia e Corriedale). Os cordeiros com peso médio inicial de 12,1 ± 1,05 kg foram alimentados com uma mistura de 30% silagem de milho, 35% farelo de soja, 34% de feno de aveia e 1% de vitaminas e minerais, ad libitum. As amostras de Longissimus dorsi foram submetidas as análises de umidade, cinza, proteína bruta, lipídios totais e perfil de ácidos graxos. O ácido graxo majoritário em todas as amostras foi o oleico (18:1 n-9). A concentra o de ácidos graxos saturados (AGS) aumentou (p < 0,05) com o peso de abate, enquanto os monoinsaturados e poli-insaturados (AGPI) diminuiram. Os cordeiros abatidos com 28 e 36 kg apresentaram raz o n-6/n-3 (2,9 e 2,85, respectivamente) dentro das recomenda es para humanos (máximo 4,0). Os resultados globais mostram que o abate de cordeiros com 28 kg resultou em melhor qualidade da carne como demonstrado por índices nutricionais para uso humano (AGPI/AGS e raz o n-6/n-3) e concentra es de proteína bruta (16,02%) e lipídios totais (13,24%).

Acta Botanica Brasilica , 2009, DOI: 10.1590/S0102-33062009000200015
Abstract: this work aimed to study the anatomy and basic density of caesalpinia pyramidalis wood, used by local populations in the municipalities of serra talhada and sertania (pernambuco), to assess the percentage of wood elements in the trunk and branches in both localities, and in the tree itself, in order to establish total wood potential for energy production. samples of the trunk (dbh) and of branches from six trees of the species were collected in 2002. sample analysis followed the usual methods of wood anatomy studies. based on the anatomical parameters of the trunk and the high basic density (>0.84 g/cm3), we conclude that caesalpinia pyramidalis wood contains an enormous amount of cellulose and lignin. due to these features, this species showed good perspectives for the production of alcohol and charcoal. the trunk and branches can be used for fuel even at the immature stage because of high fiber concentration, low vessel concentration and low amount of parenchyma at this stage in both municipalities.

Abstract: due to the economic importance of the wood of mimosa l. species in northeastern brazil's caatinga and to the fact that mimosa ophtalmocentra mart. ex benth. ("jurema-de-imbira") is confused with mimosa tenuiflora (willd.) poir. ("jurema-preta") and vice versa, this research aimed to present new data related to the anatomy and basic density of the wood of both species; to contribute to the taxonomic study for differentiating them; to identify anatomical characters of the wood relating them to the caatinga environment; and to present the energetic potential that they possess. the anatomical study and wood density determination were carried out with samples at dbh level and with two branches of individuals within the municipalities of serra talhada and sertania (pernambuco). the species both differed in bark type, color of heartwood and sapwood, besides the different anatomical characteristics found in the wood. mimosa ophtalmocentra has distinct growth layers consisting of parenchyma lines containing crystals, scarce parenchyma and smaller quantity of rays. mimosa tenuiflora, on the other hand, also has growth layers, but without crystals, axial parenchyma vasicentric, confluent and in bands, and greater percentage of rays. both species have some wood elements with anatomical characteristics typical of representatives of mimosa, contributing therefore to a better taxonomic understanding of the genus. based on wood anatomical parameters and elevated basic density (> 0.84 g/cm3), the conclusion was reached that both species have great perspectives for the production of fuel alcohol and charcoal since juvenile wood age. because mimosa ophthalmocentra has scarce parenchyma and fewer rays, it shows greater energetic potential than mimosa tenuiflora.

Abstract: Water has a decisive influence on populations’ life quality – specifically in areas like urban supply, drainage, and effluents treatment – due to its sound impact over public health. Water rational use constitutes the greatest challenge faced by water demand management, mainly with regard to urban household water consumption. This makes it important to develop researches to assist water managers and public policy-makers in planning and formulating water demand measures which may allow urban water rational use to be met. This work utilized the multivariate techniques Factor Analysis and Multiple Linear Regression Analysis – in order to determine the participation level of socioeconomic and climatic variables in monthly urban household consumption changes – applying them to two districts of Campina Grande city (State of Paraíba, Brazil). The districts were chosen based on socioeconomic criterion (income level) so as to evaluate their water consumer’s behavior. A 9-year monthly data series (from year 2000 up to 2008) was utilized, comprising family income, water tariff, and quantity of household connections (economies) – as socioeconomic variables – and average temperature and precipitation, as climatic variables. For both the selected districts of Campina Grande city, the obtained results point out the variables “water tariff” and “family income” as indicators of these district’s household consumption.

Revista da Sociedade Brasileira de Medicina Tropical , 2009, DOI: 10.1590/S0037-86822009000600001
Abstract: this study aimed to evaluate the chagas disease control program which has operated since 1982 in the municipality of berilo in the jequitinhonha valley, minas gerais, brazil, based on evaluation of 5,242 domiciliary units (dus) and 7,807 outbuildings over an eight-year period of epidemiological surveillance implanted in 1997. a total of 391 triatomines (280 panstrongylus megistus and 111 triatoma pseudomaculata) were captured, indicating the continued predominance of the former species. however, triatoma pseudomaculata is clearly becoming more important in this region, with intradomiciliary colonies being detected in recent years. entomological parameters, such as dispersion (17%) and intradomiciliary infestation (0.15%) indices, are compatible with the results of the epidemiological surveillance. the majority of dus were of construction type a (plaster over bricks) or c (plaster over adobe). twenty-five percent of the inhabitants of the dus infested by triatomines were reactive in elisa, iha and iif tests for trypanosoma cruzi antigens.
