The patient was a 72 year old man who had been given non-steroidal anti-inflammatory drug (NSAID) for two years. He repeatedly developed small intestinal ileus; therefore, he underwent several imaging examinations, but the cause was not identified. He subsequently underwent a double-balloon endoscopy (DBE). The membranous stenoses were detected in the jejunum, and the biopsy specimens were take...

Com o advento do Ensino Remoto Emergencial (ERE) em 2020, uma disciplina de Bioquímica Médica e Farmacocinética um curso graduação Medicina, concebeu-se a Discussão Baseada Evidência (DBE), com objetivo substituir métodos avaliativos tradicionais abordar temas alusivos à pandemia COVID-19, pautando-se na Medicina Evidências (MBE). Para tal, grupos discentes deveriam pesquisar sobre metabolismo ...

Until recently, large parts of the small bowel were not accessible with nonsurgical endoscopic techniques. In this scenario, the advent of video capsule endoscopy and balloon−assisted ente− roscopy represented a major breakthrough. Although capsule endoscopy is a safe method that may provide imaging of the entire small bowel, major drawbacks are that biopsy sampling and endoscopic treatment can...

vides a facility for the diagnosis and treat− ment of small−intestinal disease [1]. To date its use has not been described in in− fants. A boy aged 3 years and 10 months who had small−intestinal bleeding under− went esophagogastroduodenoscopy in another hospital, when two gastric polyps were found. He was referred to us for DBE. Peutz−Jeghers syndrome was diagnosed on the basis of the findings ...

Abstract Dibutyl ether (DBE) is a promising biofuel due to its high cetane number (~ 100) and volumetric energy density (31.6 MJ/L). It could either be used directly in compression ignition engines or blended with other conventional renewable fuels. Oxidation pyrolysis kinetics of DBE are not well known, particularly at pressures. In this work, we have experimentally investigated the chemical t...

BACKGROUND Pyogenic granuloma (PG) is a polypoid lobular capillary hemangioma rarely observed in the gastrointestinal tract. Only a few cases in the small bowel have been described in the literature. CASE PRESENTATION A 58-year-old man had been suffering from general fatigue and severe anemia. Esophagogastroduodenoscopy and colonoscopy did not reveal any significant bleeding. Abdominal comput...

Degenerate band edges (DBEs) of a photonic bandgap have the form (ω-ω(D)) ∝k(2m) for integers m>1, with ω(D) the frequency at the band edge. We show theoretically that DBEs lead to efficient coupling into slow-light modes without a transition region, and that the field strength in the slow mode can far exceed that in the incoming medium. A method is proposed to create a DBE of arbitrary order m...

Abstract: One of the major issues in data cluster analysis is to decide the number of clusters or groups from a set of unlabeled data. In addition, the presentation of cluster should be analyzed to provide the accuracy of clustering objects. This paper propose a new method called Enhanced-Dark Block Extraction (E-DBE), which automatically identifies the number of objects groups in unlabeled dat...

This study identified and purified specific isoamylase- and pullulanase-type starch-debranching enzymes (DBEs) present in developing maize (Zea mays L.) endosperm. The cDNA clone Zpu1 was isolated based on its homology with a rice (Oryza sativa L.) cDNA coding for a pullulanase-type DBE. Comparison of the protein product, ZPU1, with 18 other DBEs identified motifs common to both isoamylase- and...

Each of four starch debranching enzymes (DBE) is distinct and highly conserved across the plant kingdom; however, the specific functions of these proteins in carbohydrate metabolism are not well understood. DBEs function in both biosynthesis and degradation of starch, and two have been shown to function as multimers in various quarternary structures that can contain one or more DBE proteins, i....
