Abstract
We aimed to evaluate the effects of different drying methods for banana residues on the energy metabolism and respirometry of growing lambs. Twenty Santa Inês x Dorper lambs were fed five experimental diets: Tifton 85 grass hay (Control), shade-dried banana leaf hay (LH Shade), shade-dried pseudostem banana hay (PH Shade), sun-dried banana leaf hay (LH Sun), and sun-dried banana pseudostem hay (PH Sun). Nutrient intake and digestibility were assessed in metabolic cages, whereas O2 consumption and CO2, methane, and heat production were measured in a respirometry chamber with animals fed at maintenance and ad libitum levels. Nutrient and energy intake was not influenced by diet. Pseudostem hay had higher apparent digestibility of dry matter (71.5%), organic matter (72.4%), and neutral detergent fiber (58.0%). However, this led to greater energy loss in the form of methane (12.1%). The banana residue hays and drying methods did not alter oxygen consumption, CO2 production, or heat production of animals fed ad libitum or during maintenance. On the other hand, the use of leaf hay resulted in a reduction of 24.7% in enteric methane production of animals fed ad libitum. The inclusion of pseudostem hay is recommended in sheep feedlot diet. This residue provided greater use of DM, however promoted a greater loss of energy in the form of methane, resulting in similar energy consumption. The drying methods did not reduce the availability of nutrients and the sun drying method is recommended, since it is a faster drying method.

Abstract
Twenty Santa Inês male sheep were used in a randomized block design to evaluate the effects of different levels of macauba cake (MC) on nutrient digestibility and the population of microorganism in the rumen. The animals were divided into four groups according to MC levels (0, 10, 20, and 30% of DM) and initial body weight ranging from 32.75 to 52.17 kg. Diets were isonitrogenous and formulated to attend metabolizable energy requirements, and feed intake was regulated with 10% allowance for leftovers. Each experimental period lasted 20 days, with the final 5 days reserved for sample collection. Macauba cake inclusion did not affect the dry matter, organic matter, or crude protein intake but increased the ether extract, neutral detergent fiber, and acid detergent fiber intake, mainly because of changes in the concentrations of these components in diets with a higher level of MC. With MC inclusion, a linear decreasing effect was observed for the dry matter and organic matter digestibility, and a quadratic effect with a maximum point of 21.5% was observed for the acid detergent fiber digestibility. A relative reduction of 73% in anaerobic fungal populations was observed with the lowest level of MC inclusion, and a relative increase of 162% in methanogenic populations was observed with the highest level of MC inclusion. The increasing level of macauba cake up to 30% of the diet of lambs reduced the dry matter digestibility and reduced anaerobic fungi but increased methanogenic population.

Abstract
Food allergy is triggered when there is an abnormal activation of the immune system by food allergens. Currently, there is no curative therapy for this pathological condition. Due to the immunomodulatory properties of probiotics they are potential candidates as therapeutic tools for food allergy. Therefore, the aim of this study was to evaluate the probiotic effect of Saccharomyces cerevisiae UFMG A-905 (905) in an in vivo model of food allergy. Probiotic effect was assessed by clinical, histological, immunological and microbiological parameters analysis. Furthermore, we also evaluated if 905 after inactivation has an effect, as well as if such an effect is dose dependent. Our results showed that oral administration of only viable 905 promotes a significant attenuation of tissue injury and myeloperoxidase (MPO) activity levels. Moreover, the treatment reduced interleukin 17 levels, and administration of the supernatant from the yeast culture also promoted a significant decrease in MPO levels. However, considering the systemic parameters, immunoglobulin (Ig)E and IgG anti-ovalbumin, which are essentials for triggering the allergic process, there was no effect, suggesting that the yeast promotes a local but not a systemic effect in the model evaluated. In addition, we found that only high doses of viable 905 were able to attenuate the signs of inflammation. In conclusion, oral administration of 905 led to a local effect that depends on the viability of the yeast.

Abstract
We tested whether the probability of detecting avian haemosporidia (Plasmodium and Haemoproteus) using molecular techniques differs among blood, liver, heart, and pectoral muscle tissues. We used a paired design, sampling the 4 tissue types in 55 individuals of a wild South American suboscine antbird, the white-shouldered fire-eye (Pyriglena leucoptera). We also identified parasites to cytochrome b lineage. Detection probability was significantly lower in blood compared to the other 3 tissue types combined. Eight of 22 infections were not detected in blood samples; 4-7 infections were not detected in the other individual tissues. The same parasite lineage was recovered from different tissues.

Abstract
Haemocytes circulating in the haemolymph protect insects against pathogens that enter the haemocoel. Changes in haemocyte morphology and differences in haemocyte counts during the immune response of Culex quinquefasciatus Say (Diptera: Culicidae) to microfilariae of Wuchereria bancrofti (Cobbold) (Spirurida: Onchocercidae) were investigated in the present study. The mean number of total haemocytes was significantly elevated in infected mosquitoes (P<0.001), reaching a peak on the third day post-infection. Differential counts show that mean numbers of prohaemocytes, plasmatocytes, granular cells and oenocytoids increased significantly after infection with microfilariae granulocytes compared to the control and näive groups of Cx. quinquefasciatus (P<0.05). Changes in proportional counts of haemocytes were also analysed in haemolymph perfusates of Cx. quinquefasciatus infected with W. bancrofti. On the first day post-infection, infected mosquitoes showed an increase in the proportion of prohaemocytes (18.8% compared to 9.6% for the control) and of oenocytoids (7.1% compared to 4.7% control); however, they exhibited lower levels of plasmatocytes (36.6% compared to 42.1% control) and granular cells (36.1% compared to 41.4% control). On day 14 post-infection, similar changes were observed for these haemocyte types, except that the proportion of granular cells was significantly greater than the control (41.2% compared to 31.3% control). Although an enhancement of prohaemocyte numbers was observed, this cellular type did not show any ultrastructural alteration. On the other hand, granular cells, plasmatocytes and oenocytoids presented morphological alterations indicative of innate immunological activation in mosquitoes infected with W. bancrofti.

Abstract
Mosquitoes have an efficient defence system against infection. Insect blood cells (hemocytes) play an essential role in defense against parasites and other pathogenic organisms that infect insects. We have identified by light and transmission electron microscopy six hemocytes cell types from the hemolymph of Aedes aegypti. They were: prohemocytes (20%), adipohemocytes (29%), granulocytes (16%), plasmatocytes (27%), oenocytoids (7%) and thrombocytoids (0.9%). The prohemocytes were the smallest hemocytes found in the hemolymph. Its cytoplasm occupies only a narrow area around the nucleus. The adipohemocytes were the most abundant cell type presented. These hemocytes exhibited a large lipid like vesicle and mitochondria. In electron micrographs, the granulocytes showed cytoplasm containing dilated rough endoplasmic reticulum (RER) and a round or elongated mitochondria. Electron-dense granules with a proteinaceous material were also present. The plasmatocytes were polymorphic and exhibited plasma membrane with irregular processes, philopodia and pseudopodia. Ultrastructural investigation revealed that the reticular cytoplasm showed a well-developed RER, a Golgi and vacuoles. Oenocytoids showed homogeneous cytoplasm with many mitochondria and ribosomes are scattered throughout the cytoplasm, abundant RER and a small smooth endoplasmic reticulum (SER) present at the cell poles. Thrombocytoids were very fragile and few in number. Similar characteristics were found in oenocytoids, possessing a homogeneous cytoplasm with poorly developed organelles, few mitochondria and granules.

Abstract
In the present paper, we report the results we obtained using several cytochemical techniques to analyze the infective larva of Wuchereria bancrofti. An imidazole osmium tetroxide solution was used to visualize unsaturated fatty acids. A highly contrasted material forming a continuous structure was observed on the larval surface and over the epicuticle. A strong reaction was observed on the esophagus and also on the inner secreted material. Carbohydrates containing vic-glycol groups were not observed on the cuticle of the third-stage larva of W. bancrofti submitted to the Thiéry technique. Using a panel of eight gold-labeled lectins, we found that the cuticle exhibited slight labeling with all lectins used, indicating residues of N-acetyl-D: -glucosamine, N-acetyl-galactosamine, D: -galactose, D: -manose, and L: -fucose. Surface anionic sites were visualized by using cationized ferritin particles. Treatment with trypsin partially inhibited the reaction, whereas the treatment with chondroitinase ABC, a specific enzyme for glycosaminoglycans, completely abolished the labeling with cationic particles.

Abstract
There is a high level of genetic diversity among the clinical isolates of the taxon Trypanosoma cruzi. The results of recent studies on well defined gene loci have revealed that T. cruzi can be divided into two major phylogenetic lineages, designated T. cruzi I and T. cruzi II. Further intra-lineage polymorphisms were explored, in clinical isolates from five representative regions of Brazil, using the internal transcribed spacers that flank the 5.8S ribosomal RNA gene. These regions were amplified in a PCR and the products were digested with six restriction enzymes before being subjected to RFLP analysis in polyacrylamide gels. The results were used to construct a complex evolutionary tree, in which the isolates were clustered into two major phylogenetic lineages with a low level of similarity. To investigate the evolutionary relationships between the isolates, the PCR products were cloned and sequenced. The results of the subsequent phylogenetic analysis confirmed the presence of the two major groups of T. cruzi and showed that zymodeme 3, a third iso-enzymatic sub-group, is closer to T. cruzi I than to T. cruzi II.

Abstract
Trypanosoma cruzi is currently classified into 2 major phylogenetic lineages, T. cruzi I and II, that correlate with the formerly described zymodeme 1 and 2, respectively. Another isoenzymic group (zymodeme 3-Z3) was also described. In this study, we analysed the genetic diversity among Z3 isolates of the Brazilian Amazon by restriction fragment length polymorphism of the intergenic transcribed spacers (ITSs) of the ribosomal RNA cistron and the size of the divergent domain D7 of the 24Salpha rRNA gene. DNAs from 12 T. cruzi Z3 isolates obtained from humans (2), Panstrongylus geniculatus (1), and Rhodnius brethesi (9) were submitted to PCR amplification of the ITSs plus the 5.8S rDNA. The PCR products were digested with 4 distinct endonucleases and the profiles analysed by a numerical methodology. The phenetic dendrogram revealed a clear dichotomy in the Z3 group, defining 2 groups that were named Z3-A and Z3-B. Dimorphism was also found in the band sizes of the amplified D7 divergent domain of the 24Salpha rDNA, which showed a perfect correlation with the ITSs clustering. The organization of the ribosomal cistron was investigated by Southern blotting and shown to be conserved in the genome of the 2 Z3 groups. This study shows that the rDNA cistron allows the definition of 2 distinct subclusters in Z3 isolates.

Abstract
This study aimed at evaluating the efficacy and safety of meropenem as first choice treatment for nosocomial pneumonia (NP) in intensive care units (ICU) in Hospital das Clínicas (HC) - University of São Paulo; a hospital with high incidence of antimicrobial resistance. Prospective, open, and non-comparative trial with meropenem were done in patients with ventilator-associated or aspiration NP in 2 ICUs at HC - University of São Paulo. Etiologic investigation was done through bronchoalveolar lavage and blood cultures prior to study entry. Twenty-five (25) critically ill patients with NP were enrolled (mean age 40 years). Ventilator-acquired pneumonia was responsible for 76% of cases and aspiration NP for 24%. Specific etiologic agents were identified and considered to be clinically and temporally responsible for NP in 11 (44%) patients. A. baumanii was responsible for 6 cases (55%), P. aeruginosa for 3 (27%), and S. aureus for 2 (18%). At completion of treatment, 19 patients (76%) showed either cure (48%) or improvement (28%) after use of meropenem therapy. Mortality was 12% at the end of therapy (8% after excluding 1 non-evaluable patient). After 4 to 6 weeks of follow-up, 12 (48%) patients had improved or been totally cured, and overall mortality was 24%. Clinical complications were observed in 11 patients (44%), with none of them definitely related to the study drug. Meropenem as monotherapy was effective and well-tolerated in most NP patients in our ICU. The low mortality rate in this study might have been due to first choice use of this drug. Controlled, drug comparative clinical trials are needed to support this preliminary observation.

In order to collect the data, it was used the interpersonal process, the techniques of asistematic observation, a nonstructured interview, in addition to the application of the Mini Mental Test and the Abbreviated Depression Scale by ZUNG. Were used these techniques and instruments were made possible by means of twelve home visits. The data have been analyzed qualitatively according to the Interpersonal Process between the nurse and the client, resulting in mutual help. The results gathered, made it possible for us to reflect on the helping relation according To Peplau's presuppositions, which made possible the home nursing assistance to the elderly man and contributed to improve his life quality.

Abstract
Hypertonic solutions effectively improve hemodynamic parameters in patients admitted to the emergency room. However, no significant differences in outcome were observed compared with standard isotonic treatment in most previously published studies. This study evaluates pretreatment prognostic factors that predict a beneficial effect of hypertonic solution in patients admitted to the emergency room with hemorrhagic hypovolemia in a prospective double-blind fashion. The patients (n = 212) were randomized upon admission to receive 250 mL intravenous (i.v.) bolus of hypertonic 7.5% NaCl + 6% dextran (HSD, n = 101), or isotonic 0.9% NaCl solutions (IS, n = 111) as the first treatment, followed by standard resuscitation. Pretreatment factors assessed were sex, age, cause of hypovolemia, revised trauma score (RTS), Glasgow index, and mean arterial pressure (MAP) on admission. Both groups were compared for survival at 24 h and 30 days postadmission. Infused volumes were registered. HSD administration significantly increased MAP and reduced i.v. crystalloid infusions to maintain hemodynamic parameters, compared with IS. There was no difference between groups in the number of blood transfusions administered. Overall complication rates in both groups were similar (24%). There was a significant difference (p < .03) in overall (30 days) survival rate between HSD (73%) and IS (64%) groups. The 24 h survival rate was significantly lower in IS (72%) compared with HSD (87%); p < .01. Multivariate analyses showed that RTS and MAP were identified as independent predictors for 24 h survival in the group that received HSD. When evaluated for overall survival rate, hypertonic infusion benefited significantly only patients with MAP < 70 mmHg (p < .01).

Abstract
This is a bibliographic study where the authors tried to analyse the interpersonal relationships of nursing from Hildegard E. Peplau following the conceptual pattern of analysis and evolution proposed by Thibodeau. It describes the concepts of person, environment, health and nursing; the source and procedures used to this theory formation; and its generalization, use, acceptance and significance for nursing. It shows the importance of its application in nursing practice because the interpersonal process is a primary stage in nursing assistance.
