The goal of this research was to characterize written stories, produced by students, without complaint of language development (oral and written), from pictographic support. In a specific way, it has been searched, in those stories, elements that could grant coherence, applying that performance with the participants’ profile variables. It was characterized as a descriptive-exploratory study, held at a rural municipal school in the State of Parana. Twenty-one (21) students of both genders and ages between seven and nine years old have participated in this study. Data collection consisted of two narratives requests: one oral, after being released, to the child, four pictures placed in sequence to form a story, and one written. This writing production had been taken for the analysis. The results have indicated that most children (71.42%) managed to produce coherent stories, seventeen (80%) in story 1 and thirteen (61%) in story 2. As to the relation of that coherence with the students’ profile in story 1, there has been no statistically significant association, for none of the analyzed variables (gender, age and education), whereas there has been a statistically significant association with gender in story 2 (p-value 0.027). It is considered that the use of the pictographic support in developing stories have been confirmed as a facilitating strategy for its construction, for it has enabled the production of coherent narratives.

Presence of the orthographic mistakes on the writting of the students with or without learning difficulties still is a concern. The focus of these study is the classification of orthographic mistakes on the writting of the students who had participated of the Educational Program of Resistance to the Drugs and the Violence (Proerd). Sixty four grade children from a public school were individually analyzed in this study. The aim of this study was to verify the frequency and characterization of the orthographic mistakes on the texts production these students. We had as base for this analysis the studies of Zorzi (1998). The most frequent mistakes made by students were: irregular phonographemic relation (24%), letters omission (18%), similar letters (13%) and hypo-segmentation and hyper-segmentation (11,0%), amongst others. The characterization of the mistakes writing makes possible the planning of the interventions, as well as, the use of the prevention strategies.

The present paper conducts an analysis of all steps for the construction of diaphragm walls, from obtaining the soil parameters until its execution. Construction stages of diaphragm wall are detailed. The paper presents a detailed analysis of the main available calculation methods to obtain the soil parameters and the design of the diaphragm wall. A case history extensively documented in previous research and present in international symposiums was chosen for an analysis of construction process and excavation’s instrumentations, as well as emphasizing the importance of temporary works and construction sequence for deep excavation with cast in-situ diaphragm walls. In general, it is possible to conclude the main difficulty and uncertainty of the dimensioning are obtaining the soil parameter for diaphragm wall design. And, it is also possible to conclude the monitoring and execution control are paramount to the success of the diaphragm wall construction

A extensa fragmentação das florestas tropicais e conseguinte perda da fauna de dispersores e predadores de sementes trazem importantes consequências às interações planta-animal. A predação de sementes, que representa uma etapa crítica no recrutamento de plantas tropicais, é um dos processos que sofrem com este impacto. A falta dos agentes dispersores e predadores de sementes pode alterar a dinâmica natural dessa interação trófica ao ponto de não corresponder mais ao modelo de Janzen-Connell, que prediz que quanto mais próximo da planta parental, maior a probabilidade de predação e, por conseqüência, menor será a dispersão. Esse estudo avaliou em três fragmentos com níveis diferenciado de defaunação (Mata São José, Reserva Municipal Santa Genebra e Estação Ecológica dos Caetetus) a predação (e/ou dispersão) de sementes de palmito juçara (Euterpe edulis Martius) abaixo e longe da planta-mãe, buscando testar o modelo Janzen-Connell. Em cada área cinco sementes foram dispostas em tratamento aberto e cinco em tratamento fechado, abaixo e distante 10 metros do parental em 15 palmeiras e avaliado o destino das sementes após 30 dias. Os resultados não oferecem suporte ao modelo, uma vez que apenas em um dos fragmentos pequenos e defaunados a predação abaixo do parental foi maior que distante, ou seja, nos demais fragmentos a distância da planta mãe não aumentou a sobrevivência das sementes. Nas áreas defaunadas a predação ocorreu principalmente por invertebrados e patógenos, enquanto que na área menos defaunada a predação foi feita principalmente por vertebrados. Diferenças significativas na predação de sementes entre os tratamentos só foram obtidas na área menos defaunada, o que mostra a importância dos predadores vertebrados de médio e grande porte na predação e/ou dispersão de sementes de E. edulis neste fragmento.

Inflammatory fibroid polyp (IFP) is a benign uncommon lesion (1%-4% of gastric benign lesions), originated from the submucosa of the gastrointestinal tract. Its origin is controversial and immunohistochemical studies of lesions have largely refuted the possible vascular, neural or smooth muscle origin. Recent studies suggest a neoplastic etiology due to a mutation, in some cases, in the alpha-type platelet-derived growth factor receptor gene (PDGFRa). Our objective is to report the case of a patient aged 70 years, with gastric IFP, comparing her immunohistochemical profile with those of other studies, and a brief review of the literature.

To evaluate the prevalence of hypertension and its correlation with the severity of renal injury and proteinuria in dogs with leishmaniosis, sixty-six dogs were divided into two groups. Group 1 (G1) was composed of 54 dogs included in stage 1 of chronic kidney disease (CKD), and group 2 (G2) of twelve dogs in stages 2 and 3 of CKD. Prevalence of hypertension was 28.8%, comprising 22.2% of the dogs from G1 and 58.3% from G2 (P=0.011). The mean arterial blood pressure (BP) of dogs from G1 (135.7 +/- 20.5) was lower than from G2 (170.0 +/- 26.3) (P <0.001). Urine proteincreatinine ratio (UP/C) revealed values above 0.5 in 75.7% of the dogs, with 34% presenting hypertension. All dogs with hypertension had histopathological and laboratory evidence of glomerular disease. Although there was no statistically significant correlation between elevated BP and the severity of glomerular lesions (P=0.408), there was a statistically significant correlation between elevated BP and increased UP/C in the studied population (P=0.002). Thus, dogs with leishmaniosis and renal disease must be screened for the presence of hypertension so that treatment may be instituted as early as possible, in countries where treatment is allowed, to prevent the progression of renal damage.

A laparoscopia ainda é pouco utilizada como ferramenta para técnicas de reprodução assistida em cervídeos sul-americanos, não havendo informações sobre seus efeitos e protocolos anestésicos seguros para sua realização. Objetivaramse avaliar as possíveis alterações na freqüência cardíaca (FC), respiratória (FR), saturação de oxihemoglobina (SpO2) e temperatura retal (TR) durante a laparoscopia para visualização dos órgãos reprodutivos de seis fêmeas de veado-catingueiro (Mazama gouazoubira) anestesiadas com a associação cetamina (5mg/kg), xilazina (0,3mg/kg), midazolam (0,5mg/kg) e isofluorano. Cada animal, após anestesiado, foi posicionado em decúbito dorsal para realização de duas laparoscopias com insuflação abdominal de CO2 (14,2 ± 2,39mmHg; M ± EPM) com intervalo de 40 dias. Para avaliar os principais eventos da laparoscopia, esta foi dividida em três períodos: animal sem insuflação abdominal (P1), com insuflação abdominal (P2) e insuflação abdominal com os quadris elevados a 45º (P3). O controle foi realizado após 40 dias da última laparoscopia, para isto, cada animal foi novamente anestesiado e mantido em decúbito dorsal por um período de tempo igual ao tempo médio de duração das anestesias realizadas nas laparoscopias, sem que o procedimento laparoscópico fosse realizado. O tempo de anestesia dos controles foi também dividido em P1, P2 e P3, respeitando o tempo médio de duração de cada um destes períodos das laparoscopias. Para análise dos dados foi usado o teste de análise de variância (ANOVA) seguido do teste de Tukey e valores de P<0,05 considerados significativos. Não houve diferença significativa nos parâmetros estudados em nenhum dos períodos estabelecidos para o controle e laparoscopia. Porém, a FR média entre P1 (38,8 ± 4,42) e P3 (32,7 ± 4,81) e a TR média entre P1 (38,2ºC ± 0,17), P2 (37,6ºC ± 0,19) e P3 (37,0ºC ± 0,21) variaram significativamente, independente da laparoscopia. Tais dados permitiram concluir que a laparoscopia não promoveu alterações significativas nos parâmetros avaliados, embora o protocolo anestésico utilizado tenha contribuído para redução da temperatura retal resultando em risco de hipotermia durante a anestesia.

The aim of the present study was to determine the coinfection of Leishmania sp. with Toxoplasma gondii, Feline Immunodeficiency Virus (FIV) and Feline Leukemia Virus (FeLV) in a population of cats from an endemic area for zoonotic visceral leishmaniasis. An overall 66/302 (21.85%) cats were found positive for Leishmania sp., with infection determined by direct parasitological examination in 30/302(9.93%), by serology in 46/302(15.23%) and by both in 10/302 (3.31%) cats. Real time PCR followed by amplicon sequencing successfully confirmed Leishmania infantum (syn Leishmania chagasi) infection. Out of the Leishmania infected cats, coinfection with FIV was observed in 12/66(18.18%), with T. gondii in 17/66 (25.75%) and with both agents in 5/66(7.58%) cats. FeLV was found only in a single adult cat with no Leishmania infection. A positive association was observed in coinfection of Leishmania and FIV (p < 0.0001), but not with T. gondii (p > 0.05). In conclusion, cats living in endemic areas of visceral leishmaniasis are significantly more likely to be coinfected with Fly, which may present confounding clinical signs and therefore cats in such areas should be always carefully screened for coinfections.
