Abstract: Non-atrophic active chronic gastritis (ACG) is characterized by the presence of H. pylori in the gastric epithelium, known to be one of the first steps that precede progression to gastric adenocarcinoma. Inactive chronic gastritis (ICG) suggests that the patient has H. pylori gastritis, but this diagnosis is rarely made in routine histopathology. Clinical manifestations associated with H. pylori infection are potentially due to differences in virulence between strains; however, it is unclear if the progression of ACG to ICG depends on the H. pylori strain. The aim of this study was to compare the prevalence of the virulence factors of H. pylori found in patients with ACG and ICG, and its influence on the development of ICG. A significant association was observed between H. pylori detection by histological examination and the activity of gastritis (p < 0.01). Long-term use of proton pump inhibitors (PPI) (>1 year) was reported by 28.6% of the ACG group and 42.5% of the ICG, while no evidence of association between long-term use of PPI and decreased inflammation was found in the patients studied. The genes cagA, cagE and virB11 were statistically associated with ACG (p = 0.01, p < 0.001 and p = 0.002, respectively). In the vacAs1 allele groups, ACG was associated with the most virulent group (p = 0.0015), while ICG was associated with the less virulent group (p < 0.001). The rate of co-infection was significantly higher in ICG than in ACG cases (p = 0.02). In conclusion, this study points to the role of virulent strains of H. pylori in the non-resolution of gastritis.

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: psychotria l. (rubiaceae) is the genus with the most heterostylous species in the angiosperms. the objective of this study is to describe floral biology, phenology, reproductive system, and pollinators of psychotria poeppigiana müll. arg. the terminal inflorescences are capitate with red bracts and yellow flowers, and presented two different morphs: pin and thrum, characterized by hermaphroditic flowers with different lengths of styles and opposed position of the anthers (reciprocal herkogamy). dimorphism was also observed in the size of anthers, pollen grains and stigmatic surfaces. controlled pollination revealed self-incompatibility and intramorph-incompatibility at the level of stigma and style. wasps, butterflies and hummingbirds visited the flowers, especially in early morning. according to the frequency of visits and an efficient transport of pollen between floral morphs, the hummingbird thalurania furcata was the main pollinator. little nectar (max. 8μl) was produced during the opening of the flowers (5:00-7:00h). because of vegetative reproduction the species forms clumps.

Abstract: the production system using cages is a highly polemical issue in europe, because of the space restriction imposed to laying hens. it is considered that the cage system might compromise important comfort movements, welfare and egg quality. this study evaluated egg quality and welfare of two strains of hens housed in a conventional system (battery laying cages) or litter system with nest and perches, and submitted to heat stress or comfort conditions. two groups of 20 birds (10 hy-line w36 and 10 hy-line brown) were submitted to two environmental conditions (26°c and 60% rh or 35°c and 70% rh) and two housing systems (cages or litter) in the early production phase. egg quality was analyzed based on egg weight, eggshell thickness, specific gravity, and haugh units. yolk and shell contamination by salmonella sp was also assessed. a significant (p<0.05) reduction in quality parameters was observed in eggs produced by laying hens under heat stress, mainly in the birds housed in cages.

Abstract: detailed studies of pedologic characterization, as well as of relationships between pedology, geology and geomorphology are important for the comprehension of the soil distribution in a landscape. the objective of this study was to evaluate the pedomorphogeological relationships in the chapadas elevadas of the distrito federal, by the chemical, physical, mineralogical and geochemical characterization of the soils found in this landscape compartment. two representative top-sequences of the pedologic distribution were selected in this geomorphologic unit, whose soils were formed from metasedimentary rocks of the grupo paranoá, represented by red oxisols (latosols), yellow-red oxisols and cambisols. the physical, chemical and mineralogical properties of the oxisols of the two top-sequences were mostly similar. the color variation in the oxisols was due to the differentiated fe oxide mineralogy - predominantly hematite in lv and goethite in lva. however, the icp-aes analysis showed similar fe2o3 levels in oxisols, indicating a material of origin (metasedimentary rock) with similar geochemical composition. the goethite formation in lva was related to the geomorphological position of development, on the edges of the plateau, where the water table oscillation resulted in the formation of a lithoplintic horizon, with consequently deficient drainage conditions. the cambisols were chemically similar to oxisols, due to the source material, consisting of pre-weathered sedimentary rock. the pedomorphogeological relations showed that the soil distribution in the chapadas elevadas of the distrito federal is linked to the geomorphologic evolution and regional geology.
