Sidney Pereira Pinto Lemos, Patrícia Veruska Ribeiro Barbosa Lemos, Natália Araújo Lima Rocha Coelho, Danielle Moreira de Abrêu, Lucas Barbosa Ribeiro Feitosa
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.

Abstract: Objective: This study aimed to evaluate the accuracy of different calibration endodontic rulers used for calibration of gutta-percha cones. Methods: Three hundred and sixty gutta-percha cones were calibrated by three different calibration endodontic rulers ( ngelus , Prisma and Maillefer ) in the holes #25, #30, #35, #40, #45 and #50. The diameter of the calibrated end of each cone was measured by two examiners using a digital caliper. Data were organized into a table and statistically analyzed with ANOVA and Bonferroni test with a significance level of 5%. Results: The bestcalibration results were obtained by Prisma (0.023 mm ± 0.002 mm), while the others presented the worst results of calibration with no statistical difference between them: ngelus (0.028 mm ± 0.002 mm) and Maillefer (0.030 mm ± 0.002 mm). Conclusion: It can be concluded that the rule Prisma had on average a higher result in the standardization of gutta-percha cones, followed by ngelus and Maillefer .

Abstract: Ancestry-informative markers (AIMs) show high allele frequency divergence between different ancestral or geographically distant populations. These genetic markers are especially useful in inferring the likely ancestral origin of an individual or estimating the apportionment of ancestry components in admixed individuals or populations. The study of AIMs is of great interest in clinical genetics research, particularly to detect and correct for population substructure effects in case-control association studies, but also in population and forensic genetics studies. This work presents a set of 46 ancestry-informative insertion deletion polymorphisms selected to efficiently measure population admixture proportions of four different origins (African, European, East Asian and Native American). All markers are analyzed in short fragments (under 230 basepairs) through a single PCR followed by capillary electrophoresis (CE) allowing a very simple one tube PCR-to-CE approach. HGDP-CEPH diversity panel samples from the four groups, together with Oceanians, were genotyped to evaluate the efficiency of the assay in clustering populations from different continental origins and to establish reference databases. In addition, other populations from diverse geographic origins were tested using the HGDP-CEPH samples as reference data. The results revealed that the AIM-INDEL set developed is highly efficient at inferring the ancestry of individuals and provides good estimates of ancestry proportions at the population level. In conclusion, we have optimized the multiplexed genotyping of 46 AIM-INDELs in a simple and informative assay, enabling a more straightforward alternative to the commonly available AIM-SNP typing methods dependent on complex, multi-step protocols or implementation of large-scale genotyping technologies.

Abstract: sugar apple (annona squamosa l) is a tropical fruit tree that has been cultivated in alagoas for more than a century. it is one of the most important crop for hundreds of small farmers. one of the main constraints to improve this culture yield is its low pollination rate of their flowers. although morphologicaly perfects, the flowers of sugar apple present the carpels maturation before pollen liberation in the anters preventing self-pollination. this work had the objective to study the effect of the natural, artificial and self-pollination on the number of fixed fruits in sugar apple. it was selected 40 four-year-old trees of local variety "crioula" and flowers of the mean portion of the trees. they were applied the following treatments: natural pollination; self-pollination; hand pollination with 100% pollen using paintbrush; hand pollination with 75 % of pollen and 25 % starch using paintbrush; hand pollination with 50 % of pollen and 50 % starch using paintbrush; hand pollination with 25 % of pollen and 50 % starch using paintbrush; hand pollination with 100 % of pollen using sprayer; hand pollination with 75 % of pollen and 25 % starch using sprayer; hand pollination with 50 % of pollen and 50 % starch using sprayer; hand pollination with 25 % of pollen and 75 % starch using sprayer. the results showed that the hand pollination with paintbrush or sprayer improved by ten fold the number of fixed fruits in natural pollination. the addition of starch to the pollen up to 50% of the mixture produced the same result of pure pollen.

Abstract: the objective of this study was to determine the adaptability and stability of varieties and hybrids of corn, when subjected to different environmental conditions in the mid-northern region of brazil. for this, we proceeded to the assessment of 22 hybrids in an experimental grid, and 20 cultivars (varieties and hybrids) in another grid, in different environments, using an experimental design of randomized blocks with three replications. the hybrids showed better adaptation than did the varieties. in both grids differences were detected among genotypes and environments, and inconsistent behavior of these genotypes was detected across the average of the environments. the cultivars differed in their adaptability in unfavorable environments. among those cultivars which best adapted (b0>overall average), the hybrids pl 1335 and shs 5050, and the variety shs 500, showed to be demanding under unfavorable conditions (b1>1) and the hybrid shs 5070 and variety al 34, proved to be undemanding under these same conditions (b 1<1). the hybrids which demonstrated wide adaptability (b0> overall average and b1=1) such as: dkb 390, das 8480, dkb 455, brs 1010 and brs 1030, among others, become important for agriculture in the region.
O conceito de transferência nos "Estudos sobre a histeria" (Breuer & Freud, 1895)
Bissoli, Sidney da Silva Pereira;
Paidéia (Ribeir?o Preto) , 2006, DOI: 10.1590/S0103-863X2006000100004
Abstract: this article is part of a larger project, in which it intends to examine how the concept of transference is dealt in freudian's psychoanalysis. as the notion of transference appears by the first time in chapter 4 of "estudos sobre a histeria", this work acquires the status of the starting point to the examination of that. it verifies that the notion of transference can't ever be understood as the whole relationship that a patient establishes with his psychoanalyst. it can't either be understood as the total perturbation in this type of relationship, as it was further interpreted by other authors. it is only a very specific point of this relationship, in which, through a false bond, and in an uncommon way, the figure of the doctor replaces someone from the patient's past.

Abstract: To evaluate the effect of a cyclooxygenase 2 inhibitor, celecoxib (CEL), on bladder cancer inhibition in a rat model, when used as preventive versus as curative treatment. The study comprised 52 male Wistar rats, divided in 5 groups, during a 20-week protocol: control: vehicle, carcinogen: 0.05% of N-butyl-N-(4-hydroxybutyl) nitrosamine (BBN), CEL: 10?mg/kg/day of the selective COX-2 inhibitor Celebrex, preventive CEL (CEL+BBN-P), and curative CEL (BBN+CEL-C) groups. Although tumor growth was markedly inhibited by the preventive application of CEL, it was even aggravated by the curative treatment. The incidence of gross bladder carcinoma was: control 0/8(0%), BBN 13/20(65%), CEL 0/8(0%), CEL+BBN-P 1/8(12.5%), and BBN+CEL-C 6/8(75%). The number and volume of carcinomas were significantly lower in the CEL+BBN-P versus BBN, accompanied by an ample reduction in hyperplasia, dysplasia, and papillary tumors as well as COX-2 immunostaining. In spite of the reduction of tumor volumes in the curative BBN+CEL-C group, tumor malignancy was augmented. An anti-inflammatory and antioxidant profile was encountered only in the group under preventive treatment. In conclusion, preventive, but not curative, celecoxib treatment promoted a striking inhibitory effect on bladder cancer development, reinforcing the potential role of chemopreventive strategies based on cyclooxygenase 2 inhibition. 1. Introduction Bladder cancer is a prevalent tumor, accounting for 5%–10% of all malignancies in Western countries [1, 2]. It has a high recurrence and progression rate and the prognosis, except for superficial forms, is poor [3]. Furthermore, it has high mortality rates and socioeconomic costs [4, 5]. The conventional surgical techniques and therapeutic options might cause discomfort to patients, especially in invasive and aggressive forms of cancer [6, 7]. Therefore, the improvement of bladder cancer management and treatment could rely on better preventive strategies. The identification of promising drugs remains dependent on a better elucidation of the molecular/cellular mechanisms underlying cancer appearance and progression [8, 9]. Apart from the genetic features and markers already characterized [10, 11], the cellular and molecular mechanisms for development and/or progression might involve inflammatory, proliferative, and oxidative stress phenomena that should be better elucidated. Inflammation through the cyclooxygenase (COX) pathway has been involved in cancer development [12]. While COX-1 is constitutively expressed in a huge range of tissues, playing a role in
