| 1 | Mechanical properties of the A356 aluminum alloy modified with La/Ce显示文摘The research of rare earths for the synthesis of materials with improved mechanical performance is of great interest when they are considered for potential applications in the automotive industry. In this regard, the effect on the mechanical properties and microstructure of the automotive A356 aluminum alloy reinforced with 0.2 (wt.%) Al-6Ce-3La (ACL) was investigated. The ACL was added to the melted A356 alloy in the as-received condition and processed by mechanical milling. In the second route, the effect of the ACL processed by mechanical milling and powder metallurgy techniques was investigated, and compared with the results obtained from the A356 alloy strengthened with ACL in the as-received condition. Microstructural properties were evaluated by means of X-ray diffraction in order to observe the solubility of Ce/La in the Al matrix. In addition, electron microscopy was employed in order to investigate the effect of milling time on the size and morphology of La/Ce phase under milling process. Mechanical properties of the A356 alloy modified with ACL were measured by hardness and tensile test. For comparison unmodified specimens of the A356 were characterized according to the previous procedure. The microstructural and mechanical characterization was carried out in specimens after solution and artificial aging. Observations in scanning electron microscopy indicated a homogeneous dispersion of La/Ce phases by using both routes; however, mechanical results, in the modified A356 alloy with the ACL in the as-received condition, showed an improvement in the mechanical performance of the A356 alloy over that reinforced with the ACL mechanically milled. | E.

| 2 | Association between Helicobacter spp.infections and hepatobiliary malignancies:A review显示文摘Hepatobiliary cancers are highly lethal cancers that comprise a spectrum of invasive carcinomas originating in the liver hepatocellular carcinoma,the bile ducts intrahepatic cholangiocarcinoma and extrahepaticcholangiocarcinoma,the gallbladder and the ampulla of Vater(collectively known as biliary tract cancers).These tumors account for approximately 13% of all annual cancer-related deaths worldwide and for 10%-20% of deaths from hepatobiliary malignancies.Cholangiocarcinoma(CCA) is a devastating disease that displays a poor survival rate for which few therapeutic options are available.Population genetics,geographical and environmental factors,cholelithiasis,obesity,parity,and endemic infection with liver flukes have been identified as risk factors that influence the development of biliary tract tumors.Other important factors affecting the carcinogenesis of these tumors include chronic inflammation,obstruction of the bile ducts,and impaired bile flow.It has been suggested that CCA is caused by infection with Helicobacter species,such as Helicobacter bilis and Helicobacter hepaticus,in a manner that is similar to the reported role of Helicobacter pylori in distal gastric cancer.Due to the difficulty in culturing these Helicobacter species,molecular methods,such as polymerase chain reaction and sequencing,or immunologic assays have become the methods of choice for diagnosis.However,clinical studies of benign or malignant biliary tract diseases revealed remarkable variability in the methods and the findings,and the use of uniform and validated techniques is needed. | Fany Karina Segura-López Alfredo Güitrón-Cantú Javier Torres | 2015 | World Journal of Gastroenterology2015，21，5： | 9 |
| 3 | Gastroenterology case report of mesalazine-induced cardiopulmonary hypersensitivity显示文摘Mesalazine is a 5-aminosalicylic acid derivative that has been widely used to treat patients with inflammatory bowel disease. Accumulating evidence indicates that mesalazine has a very low rate of adverse drug reactions and is well tolerated by patients. However, a few cases of pulmonary and cardiac disease related to mesalazine have been reported in the past, though infrequently, preventing clinicians from diagnosing the conditions early. We describe the case of a 32-yearold man with ulcerative colitis who was admitted with a two-month history of persistent fever following mesalazine treatment initiated 14 mo earlier. At the time of admission, mesalazine dose was increased from 1.5 to 3.0 g/d, and antibiotic therapy was started with no improvement. Three weeks after admission, the patient developed dyspnea, non-productive cough, and chest pain. Severe eosinophilia was detected in laboratory tests, and a computed tomography scan revealed interstitial infiltrates in both lungs, as well as a large pericardial effusion. The bronchoalveolar lavage reported a CD4/CD8 ratio of 0.5, and an increased eosinophil count. Transbronchial biopsy examination showed a severe eosinophilic infiltrate of the lung tissue. Mesalazine-induced cardiopulmonary hypersensitivity was suspected after excluding other possible etiologies. Consequently, mesalazine treatment was suspended, and corticosteroid therapy was initiated, resulting in resolution of symptoms and radiologic abnormalities. We conclude that mesalazine-induced pulmonary and cardiac hypersensitivity should always be considered in the differential diagnosis of unexplained cardiopulmonary symptoms and radiographic abnormalities in patients with inflammatory bowel disease. | José Ferrusquía Isabel Pérez-Martínez Ricardo Gómez de la Torre María Luisa Fernández-Almira Ruth de Francisco Luis Rodrigo Sabino Riestra | 2015 | World Journal of Gastroenterology2015，21，13： | 5 |
| 4 | Diabetic gastroenteropathy:An underdiagnosed complication显示文摘This article is an extensive review that provides an update on the pathophysiology,symptoms,diagnosis,and treatment of diabetic gastroenteropathy.There is no reported prevalence,but it has been described that patients with type 1 diabetes have a cumulative incidence at 10 years of 5.2%,and type 2 patients,1%.Also,in the group of type 1 diabetes,it has been observed that women are more likely to present this condition(5.8%vs 3.5%).Many factors are associate with its development(e.g.,hyperglycemia,vagal dysfunction,loss of expression of neural nitric oxide synthase in the myenteric plexus,alterations in the Cajal interstitial cell network,and oxidative stress).Gastrointestinal discomfort could be perceived 70% higher in diabetic patients,describing that 25%of diabetic patients experience gastrointestinal symptoms.Diabetic enteropathy could affect any portion of the gastrointestinal tract,but esophageal alterations were described in more than 60% of diabetic patients,also 60% of them present constipation,and 20%,diarrhea.Gastric emptying scintigraphy is useful to evaluate gastroparesis,therefore,gastric retention of more than 60%at 2 h has a sensitivity of 100% and specificity of 20% for diagnosis;however,other studies such as breath tests,with a sensitivity of 89% and a specificity of 80%,or the endoscopic capsule contribute to the diagnosis.There is no cure;however,management must be multidisciplinary,focused on slowing the progression of diabetic gastroenteropathy,reducing symptoms,and restoring function;that includes nutritional recommendation,maintain glucose levels kept below 180 mg/dL,use of prokinetics,anti-emetics;nowadays,it has been special interest in surgical treatment,such as pyloroplasty,also gastric electrical stimulation appears to be another alternative. | Marcio JoséConcepción Zavaleta Jhean Gabriel Gonzáles Yovera Diego Martín Moreno Marreros Luciana del Pilar Rafael Robles Kely Roxana Palomino Taype Karen Nohelly Soto Gálvez Luis Fernando Arriola Torres Julia Cristina Coronado Arroyo Luis Alberto Concepción Urteaga | 2021 | World Journal of Diabetes2021，12，6： | 4 |
| 5 | Conservative management of perforated duodenal diverticulum: A case report and review of the literature显示文摘Duodenal diverticula are a relatively common condition. They are asymptomatic, unless they become complicated, with perforation being the rarest but most severe complication. Surgical treatment is the most frequently performed approach. We report the case of a patient with a perforated duodenal diverticulum, which was diagnosed early and treated conservatively with antibiotics and percutaneous drainage of secondary retroperitoneal abscesses. We suggest this method could be an acceptable option for the management of similar cases, provided that the patient is in good general condition and without septic signs. | David Martínez-Cecilia Alvaro Arjona Sánchez Manuel Gómez álvarez Eva Torres Tordera Antonio Luque Molina Victor Valentí Azcárate Javier Briceo Delgado Francisco Javier Padillo Pedro López-Cillero Sebastián Rufián Pea | 2008 | World Journal of Gastroenterology2008，14，12： | 2 |
