Case Reports in Clinical Medicine (CRCM) , 2015, DOI: 10.4236/crcm.2015.43025
Introduction: Advances in prenatal imaging studies have allowed early diagnosis of Congenital Diaphragmatic Hernia (CDH), although neonatal mortality remains at high levels (60% survival). Despite advances, this study found delayed diagnosis, demonstrating subdiagnosis, possibly caused by lack of resources and/or prenatal diagnostic failure. Case Report 1: Infant, 4 months and 22 days old, dyspneic, cyanotic, with fever and vomiting for 3 days, treated as pneumonia. After the second chest radiography, a right CDH was revealed. Surgical correction was performed and removal of Meckel’s diverticulum was surgical findings. The patient was discharged on the 10th days after admission. Case Report 2: Infant, 11 months and 3 days old, distended abdomen, with fever and dyspnea for 2 days, treated as pneumonia. After the second chest radiography, a left CDH was revealed. The patient was submitted to surgery, intestinal loop incarceration without necrosis was observed, and the correction of CDH was performed. The patient was discharged on the 7th day after admission. Discussion: Three cases, between July 2012 and July 2013, were diagnosed at Dom Malam Hospital; 2 Cases of CDH, with delayed diagnosis, showed incidence of 66.66%. Delayed diagnosis of these patients with initial hypotheses of pneumonia demonstrated high risk, emphasizing the importance of diagnosis research through observation of the clinical course, the correct imaging interpretation, in order to establish early diagnosis and treatment.

This study evaluated the nutritional characteristics of Brachiaria brizantha cultivars subjected to three cutting intensities in the course of one year. The experiment was conducted at the University of Rio Verde. The experiment was performed as a randomized 3 × 3 factorial in complete block design with three replications and repeated measures in the time. Three Brachiaria brizantha cultivars (Marandu palisadegrass, Xaraes palisadegrass, and Piata palisadegrass), were tested at three cutting intensities (10, 20, and 30 cm sward height). The evaluations were conducted on the same plots throughout one year and during all four seasons (autumn, winter, spring, and summer). The results showed that the Piata palisadegrass had the best chemical composition compared to the Marandu palisadegrass and Xaraes palisadegrass. The management of Brachiaria brizantha cultivars at the lowest residual height (10 cm) affected the nutritional value of these feed grasses. Seasonality also influenced the nutritional value of these forages.

Revista da Faculdade de Letras : Historia , 2011,
Abstract: The decades of the thirties and forties of the portuguese twentieth century are, within the rather irregular path of national cinema, the era of greater regularity. Indeed, it was this interwar period which saw considerable development of national cinematic life. This proved to be a dynamic time, both in terms of production, with the advent of sound films and national producers and their studios, both as regards to consumption, with the proliferation of cinemas; there was still the advent of magazines, like Kino, Imagem or Cinéfilo, and the emergence of important portuguese filmmakers – António Lopes Ribeiro, Leit o de Barros, Jorge Brum do Canto, Chianca Garcia – producing relevant cinematographic works. Therefore, this article aims to present the national cinematographic project, enabling a clearer understanding of its development, in the period of construction of Estado Novo

Abstract: Nesta investiga o procurou-se identificar e caracterizar as concep es que os alunos do ensino secundário possuem sobre o infinito através da análise de um questionário respondido por 829 estudantes deste nível de ensino provenientes de 7 escolas. Formulou-se a quest o de investiga o: “há diferen as em rela o às variáveis ano escolar e interpreta o da no o de infinito, entre os alunos do ensino secundário?” e verificou-se que relativamente a alguns conceitos associados ao infinito, o 12o ano apresenta melhores resultados que os restantes anos de escolaridade, no entanto quando se passa para a compara o de cardinais de conjuntos infinitos n o há diferen as significativas entre os diferentes anos de escolaridade, tratando-se de um conceito n o intuitivo. Palavras-chave: Infinito Actual. Infinito Potencial. Ensino Secundário. In this research we tried to identify and characterize high student’s conceptions of infinity through the analyses of 829 questionnaires answered in 7 different schools. It was formulated the investigation question: “Is there any difference in school year and conceptions of infinity, between the high school students?” and we verified that some associated ideas with the infinity are best understood by the 12o class, but with the infinity cardinal’s correspondences there are no significance differences between the different school years, because it is a non intuitive concept. Keywords: Cardinal’s Infinite. Potential’s Infinite. Secondary School.

Abstract: The present data show a fast and efficient biological sample processing method for the extraction of thiamine (vitamin B1) and its mono-(TMP) and di-(TDP) phosphate esters from hippocampus, thalamus and prefrontal cortex (PFC) and blood sample of the rodents. In addition, using the hippocampus and standards of these three compounds we validated an isocratic fluorescence HPLC procedure for a simultaneous detection of them in a single chromatogram within a total run time of about 12 min. Reproducibility for TDP, TMP and B1 was 2.66%, 4.50% and 7.43% (intraday) and 37.54%, 25.39% and 25.87% (interday), respectively. Recovery assays were between 96.0% and 101.7%. The calibration curves were linear and the concentrations of the three compounds, all in nanomolar range, were determined in the brain areas and in the blood samples. When compared to the current methods in the literature, this new method provides information on essential variables, such as linearity range and limit of detection, reproducibility and stability of thiamine, TMP and TDP in rat brain samples. The present data on sample processing and B1 and its phosphate ester level determinations are the first to be validated using hippocampus samples of rats.

Abstract: In the present study we evaluated the effects of chronic exposure to sounds at 22 kHz during pregnancy on the central serotonergic and behavioral parameters in Wistar rat dams after the suckling period and on their male rat offspring. In addition, we also assessed the effects of an acute 22 kHz sound, associated with the chronic intrauterine exposure, on the emotional responses of adult offspring. The primary hypothesis was that experiencing 22 kHz stimuli during an early stage of development would interfere with brain serotonergic parameters and, later, with the adult rat’s defensive responses. The corollary question was whether a 22 kHz sound exposure would differentially affect inhibitory avoidance and escape responses and central serotonergic parameters. Female rats were divided into four groups: non-pregnant control; non-pregnant chronic exposure; pregnant control; and pregnant chronic exposure. Male offspring were divided into four groups: chronic intrauterine sound exposure; acute sound exposure in adulthood; chronic intrauterine exposure with acute exposure in adulthood; and no exposure. Chronic sound exposure affected inhibitory avoidance and serotonergic parameters in female rats. For offspring, there was an interaction between chronic and acute sound exposure effects on inhibitory avoidance response but not on escape response. There were significant effects of chronic intrauterine exposure on serotonin turnover in the hippocampus and PFC of females. For offspring, the turnover was increased by chronic exposure only in PFC, and in amygdala it was increased by acute exposure. These results illuminate the potential of an early acoustic sound exposure for causing central serotonergic and emotional behavioral changes that can persist into later periods of life.
