ABSTRACT
The objective of this study was to determine the metabolizable energy, standardized ileal amino acid digestibility (SIAAD) and digestible amino acid values of wheat meal (WM), wheat gluten meal (WGM), meat bone meal (MBM) and poultry-by-product meal (PPM) in diets for broilers. In the first experiment, the total excreta collection method was used, with 180 chicks with 14 days, distributed in a completely randomized design, with 4 feeds + reference diet with 6 replicates and 6 broilers each. In the second experiment, 180 broilers from 24 to 28 days old were used, distributed in a completely randomized design, with 4 feeds + one protein free diet with 6 replicates and 6 broilers each. The AMEn values of WM, WGM, MBM and PPM were 3052, 3174, 1556 and 3200 (kcal/kg), respectively. The average SIAAD of the essential and non-essential amino acids of WM, WGM, MBM and PPM were 74.21, 97.50, 69.28 and 83.08; 76.32, 96.42, 63.93 and 77.66, respectively. The values of the main digestible limiting amino acids were 0.18, 1.42, 0.41 and 0.94 for methionine; 0.20, 1.48, 1.73 and 2.73 for lysine; 0.23, 1.67, 0.72 and 1.89 for threonine; and 0.35, 3.22, 1.38 and 2.47 for valine, respectively for the feedstuffs in study.(AU)

Objetivou-se determinar a composição química, os valores energéticos e os coeficientes de digestibilidade ileal verdadeira de aminoácidos de sojas integrais tostadas de cinco regiões. No primeiro experimento, foram utilizados 288 pintos de corte machos da linhagem Cobb 500, com 13 dias de idade e peso médio de 420,0±5,0g. O delineamento experimental utilizado foi inteiramente ao acaso, com seis tratamentos (cinco sojas integrais e uma ração referência) e oito repetições de seis aves. No segundo experimento, foram utilizados 288 frangos de corte machos da linhagem Cobb 500, com 24 dias de idade e peso médio de 865,0±20,0g. O delineamento experimental utilizado foi inteiramente ao acaso, com seis tratamentos (cinco sojas integrais e uma ração isenta de proteína à base de amido) e oito repetições de seis aves. Não houve diferença em relação aos teores de EMAn e de CEMAn (P>0,05) entre as sojas integrais. Os valores médios de EMAn, CEMAn situaram-se entre 3152 e 3399kcal/kg e 61,15 e 65,08%, respectivamente. No entanto, houve diferença (P<0,05) entre os CAE, CANE e CPB das sojas integrais, e a amostra cinco obteve os menores valores. Os valores médios para os CAE e CANE da soja integral são de 88,96% e 87,53%, respectivamente.(AU)
The goal of this paper was to determine the chemical composition, the energy values and the amino acid true ileal digestibility coefficients of toasted full-fat soybeans from 5 regions. In the first experiment, 288 chicken broilers from Cobb 500 lineage with 13 days old and average weight of 420.0±5.0g were used. The experimental design was completely randomized with 6 treatments (5 full-fat soybean diets and 1 basal diet) and 8 replicates of 6 birds. In the second experiment, 288 chicken broilers from Cobb 500 lineage with 24 days old and average weight of 865.0±20.0g were used. The experimental design was completely randomized with 6 treatments (5 full-fat soybean diets and 1 protein-free diet based on starch) and 8 replicates of 6 birds. There was no difference regarding the AMEn and AMECn contents (P>0.05) among the full-fat soybeans. The average values of AMEn, AMECn were between 3152-3399 kcal/kg and 61.15 to 65.08%, respectively. However, there were differences (P<0.05) between CEA, CENA and CPC of full-fat soybeans, and sample 5 obtained the lowest values. The average values for CEA and CENA of the full-fat soybean are 88.96% and 87.53%, respectively.(AU)

The radial nerve is a terminal branch of the brachial plexus that innervates the entire posterior compartment of the upper limb. Researches have shown that the branches can contribute to innervation of the muscles from the anterior compartment of the arm. This study sought to identify branches of radial nerve for brachialis and coracobrachialis muscles and its clinical value during surgery. Dissection was performed in 60 arms, from 30 corpses selected from the Human Anatomy Laboratories of Universidade Estadual de Ciências da Saúde de Alagoas (UNCISAL). In each arm, three segments of the same proportion were considered (proximal, middle and distal) in order to observe the number of radial nerve branches to brachialis and coracobrachialis muscles. Branches were identified in 4 of the 60 upper limb (6.66%) with the following distribution: nerve with 1 branch to the brachialis muscle in the distal third (1.66%); with 1 branch to the middle third of the coracobrachialis (1.66%) and 5 branches to the coracobrachialis muscle in the proximal third; 1 branch being found in an upper limb (1.66 %) and 4 branches in the other upper limb (1.66 %). The event was not bilaterally in the same body, and in four cases there was no branching, but only communication with other terminal nerves of the brachial plexus. In conclusion, although most authors do not describe the possibility of the occurrence of radial nerve branches to the muscles of the anterior compartment of the arm, this condition exists as an anatomical variation.
El nervio radial es un ramo terminal del plexo braquial que inerva el compartimiento posterior del miembro superior. Diversos estudios han mostrado que sus ramos pueden contribuir a la inervación de los músculos del compartimiento anterior del brazo. El presente estudio tuvo como objetivo identificar ramos del nervio radial dirigidos a los músculos braquial y coracobraquial y su importancia clínica durante las cirugías. Para ello, se disecaron 60 brazos de 30 cuerpos formolizados en los Laboratorios de Anatomía Humana de la Universidad Estadual de Ciencias de la Salud de Alagoas, Brasil (UNCISAL). En cada brazo, se consideraron tres partes de similares proporciones (proximal, medio y distal) para localizar los ramos dirigidos a los músculos mencionados. En 4 de los 60 brazos (6,66%) se identificaron ramos con la siguiente distribución: un ramo para el músculo braquial en el tercio distal (1,66%); un ramo para el tercio medio del músculo coracobraquial (1,66%) y cinco ramos para este mismo músculo en su tercio proximal; en otro miembro (1,66%)se encontró solo un ramo y en la otra muestra (1,66%) se encontraron cuatro ramos. Ninguno de los casos fue bilateral y en los cuatro casos no había ninguna ramificación. No hubo comunicación con el nervio musculocutáneo pero si con otros ramos del plexo braquial. Aunque la mayoría de los autores no describe la posibilidad de que el nervio radial inerve a los músculos anteriores del brazo, esta disposición existe como una variación anatómica.

Calcium signalling is fundamental for muscular contractility of Schistosoma mansoni. We have previously described the presence of transport ATPases (Na+,K+-ATPase and (Ca2+-Mg2+)-ATPase) and calcium channels (ryanodine receptors - RyR) involved in control of calcium homeostasis in this worm. Here we briefly review the main technics (ATPase activity, binding with specific radioligands, fluxes of 45Ca2+ and whole worm contractions) and results obtained in order to compare the distribution patterns of these proteins: thapsigargin-sensitive (Ca2+-Mg2+)-ATPase activity and RyR co-purified in P1 and P4 fractions mainly, which is compatible with a sarcoplasmic reticulum localization, while basal ATPase (along with Na+,K+-ATPase) and thapsigargin-resistant (Ca2+-Mg2+)-ATPase have a distinct distribution, indicative of their plasma membrane localization. Finally we attempt to integrate these contributions with data from other groups in order to propose the first synoptic model for control of calcium homeostasis in S. mansoni
