| 1 | A pilot study of antioxidant potential of endophytic fungi from some Sudanese medicinal plants显示文摘Objective: To evaluate the total phenolic content and total antioxidant capacity of ethyl acetate extracts of 21 endophytic fungi isolated from five Sudanese medicinal plants: Calotropis procera, Catharanthus roseus, Euphorbia prostrate, Vernonia amygdalina and Trigonella foenumgraecum. Methods: Crude extracts of endophytic fungi and their host plants were tested by classical Folin-Ciocalteu colorimetric method to determine the total phenolic content, also total antioxidant capacity was estimated using 1,1-diphenyl-2-picrylhydrazyl free radical scavenging in vitro method. Results: Among the endophytes, endophytic fungus Aspergillus sp. from Trigonella foenum-graecum seeds demonstrated the highest both total phenolic content in term of gallic acid equivalent(GAE) [(89.9±7.1 mg GAE/g)] and antioxidant activity for 1,1-diphenyl-2-picrylhydrazyl radical scavenging assay [IC50:(18.0±0.1 μg/m L)]. A high positive linear correlation(R2=0.999 1) was found between total antioxidant capacity and total phenolic content of endophytic fungi isolated from Vernonia amygdalina. Conclusions: The present study revealed that some endophytic fungi from the five Sudanese medicinal plants could be a potential source of novel natural antioxidant compounds. | Afra Khiralla Ietidal Mohamed Justinne Thomas Beno t Mignard Rosella Spina Sakina Yagi Dominique Laurain-Mattar | 2015 | Asian Pacific Journal of Tropical Medicine2015，8，9： | 9 |
| 2 | Neurological disorders and inflammatory bowel diseases显示文摘Extraintestinal manifestations occur in about one-third of patients living with inflammatory bowel disease(IBD) and may precede the onset of gastrointestinal symptoms by many years. Neurologic disorders associated with IBD are not frequent, being reported in 3% of patients, but they often represent an important cause of morbidity and a relevant diagnostic issue. In addition, the increasing use of immunosuppressant and biological therapies for IBD may also play a pivotal role in the development of neurological disorders of different type and pathogenesis. Hence, we provide a complete and profound review of the main features of neurological complications associated with IBD, with particular reference to those related to drugs and with a specific focus on their clinical presentation and possible pathophysiological mechanisms. | Giovanni Casella Gian Eugenio Tontini Gabrio Bassotti Luca Pastorelli Vincenzo Villanacci Luisa Spina Vittorio Baldini Maurizio Vecchi | 2014 | World Journal of Gastroenterology2014，20，27： | 7 |
| 3 | Imaging of the small bowel in Crohn's disease: A review of old and new techniques显示文摘The investigation of small bowel morphology is often mandatory in many patients with Crohn's disease. Traditional radiological techniques (small bowel enteroclysis and small bowel follow-through) have long been the only suitable methods for this purpose. In recent years, several alternative imaging techniques have been proposed. To review the most recent advances in imaging studies of the small bowel, with particular reference to their possible application in Crohn's disease, we conducted a complete review of the most important studies in which traditional and newer imaging methods were performed and compared in patients with Crohn's disease. Several radiological and endoscopic techniques are now available for the study of the small bowel; each of them is characterized by a distinct profile of favourable and unfavourable features. In some cases, they may also be used as complementary rather than alternative techniques. In everyday practice, the choice of the technique to be used stands upon its availability and a careful evaluation of diagnostic accuracy, clinical usefulness, safety and cost. The recent development ofinnovative imaging techniques has opened a new and exciting area in the exploration of the small bowel in Crohn's disease patients. | Simone Saibeni Emanuele Rondonotti Andrea Iozzelli Luisa Spina Gian Eugenio Tontini Flaminia Cavallaro Camilla Ciscato Roberto de Franchis Francesco Sardanelli Maurizio Vecchi | 2007 | World Journal of Gastroenterology2007，13，24： | 6 |
| 4 | Immune response to hepatitis B virus vaccine in celiac subjects at diagnosis显示文摘AIM To evaluate hepatitis B virus(HBV) vaccine response and correlation with human leukocyte antigens(HLA) and/or gluten intake in celiac patients at diagnosis.METHODS Fifty-one patients affected by celiac disease, diagnosed at the Department of Pediatrics of the University of Catania(Italy), were recruited. All patients were tested at admission for immunization against HBV, according to findings from analysis of quantitative HBV surface antibody(anti-HBs). The anti-HBs titer was measured by enzyme-linked immunosorbent assay. Following the international standards, subjects with antibody titer < 10 IU/L were defined as non-responders. The prevalence of responders and non-responders among celiac subjects and the distribution of immunization for age were examined. In addition, the prevalence of responders and non-responders was assessed for correlation to HLA and clinical features at diagnosis of celiac disease.RESULTS The entire study population was divided into three groups according to age: 24 patients aged between 0to 5.5 years(48.9%, group A); 16 aged between 5.5 and 9.5 years(30.61%, group B); 9 aged between 9.5 and 17 years(18.75%, group C). Comparison of the percentage of responders and non-responders between the youngest and the oldest age group showed no significant difference between the two groups(P > 0.05). With regard to the HLA haplotype, comparison of the distribution of vaccination response showed no statistically significant difference between the different genotypes(homozygosity for the HLADQ2 haplotype compared with HLADQ2/DQ8 heterozygosity or other haplotypes; P > 0.05). Moreover, distribution of the responders according to clinical features of celiac disease showed no statistically significant differences(P > 0.05).CONCLUSION This prospective study confirmed the lower percentage of response to HBV vaccine in celiac subjects. However, the underlying mechanism remains unclear and further studies are needed. | Martina Filippelli Maria Teresa Garozzo Antonino Capizzi Massimo Spina Sara Manti Lucia Tardino Carmelo Salpietro Salvatore Leonardi | 2016 | World Journal of Hepatology2016，8，26： | 5 |
| 5 | Natural history of a randomized trial comparing distal spleno-renal shunt with endoscopic sclerotherapy in the prevention of variceal rebleeding:A lesson from the past显示文摘AIM: To compare endoscopic sclerotherapy (ES) with distal splenorenal shunt (DSRS) in the prevention of recurrent variceal bleeding in cirrhotic patients during a long-term follow-up period. METHODS: In 1984 we started a prospective, controlled study of patients with liver cirrhosis. Long-term follow-up presents a natural history of liver cirrhosis complicated by advanced portal hypertension. In this study the effects of 2 types of treatment, DSRS or ES, were evaluated. The study population included 80 patients with cirrhosis and portal hypertension referred to our department from October 1984 to March 1991. These patients were drawn from a pool of 282 patients who underwent either elective surgery or ES during the same period of time. Patients were assigned to one of the 2 groups according to a random number table: 40 to DSRS and 40 to ES using polidocanol. RESULTS: During the postoperative period, no DSRS patient died, while one ES patient died of uncontrolled hemorrhage. One DSRS patient had mild recurrent variceal hemorrhage despite an angiographically patent DSRS and another patient suffered duodenal ulcer rebleeding. Eight ES patients suffered at least one episode of gastrointestinal bleeding: 4 from varices and 4 from esophageal ulcerations. Eight ES patients developed transitory dysphagia. Long-term follow- up was completed in all patients except for 5 cases (2 DSRS and 3 ES patients). Five-year survival rates for shunt (73%) and ES (56%) groups were statistically different: in this follow-up period and in subsequent follow-ups this difference decreased and ceased to be of statistical relevance. The primary cause of deathbecame hepatocellular carcinoma (HCC). Four DSRS patients rebled due to duodenal ulcer, while eleven ES patients had recurrent bleeding from esophago-gastric sources (seven from varices, three from hypertensive gastropathy, one from esophageal ulcerations) and two from unknown sources. Nine DSRS and 2 ES patients developed a chronic encephalopathy; 13 DSRS and 5 ES patients suffered at least one episode of acute encephalopathy. Five ES patients had esophageal stenoses, which were successfully dilated. CONCLUSION: In a subgroup of patients with good liver function, DSRS with a correct portal-azygos disconnection more effectively prevents variceal rebleeding than ES. However, this positive effect did not influence the long-term survival because other factors (e.g. HCC) were more important in deciding the fate of the cirrhotic patients with portal hypertension. | Roberto Santambrogio Enrico Opocher Mara Costa Savino Bruno Andrea Pisani Ceretti Gian Paolo Spina | 2006 | World Journal of Gastroenterology2006，12，39： | 4 |
| 6 | Rare gastrointestinal lymphomas: the endoscopic investigation显示文摘Gastrointestinal lymphomas represent up to 10%of gastrointestinal malignancies and about one third of nonHodgkin lymphomas.The most prominent histologies are mucosa-associated lymphoid tissue lymphoma and diffuse large B-cell lymphoma.However,the gastrointestinal tract can be the site of rarer lymphoma subtypes as a primary or secondary localization.Due to their rarity and the multifaceted histology,an endoscopic classification has not been validated yet.This review aims to analyze the endoscopic presentation of rare gastrointestinal lymphomas from disease diagnosis to follow-up,according to the involved site and lymphoma subtype.Existing,new and emerging endoscopic technologies have been examined.In particular,we investigated the diagnostic,prognostic and follow-up endoscopic features of T-cell and natural killer lymphomas,lymphomatous polyposis and mantle cell lymphoma,follicular lymphoma,plasma cell related disease,gastrointestinal lymphomas in immunodeficiency and Hodgkin’s lymphoma of the gastrointestinal tract.Contrarily to more frequent gastrointestinal lymphomas,data about rare lymphomas are mostly extracted from case series and case reports.Due to the data paucity,a synergism between gastroenterologists and hematologists is required inorder to better manage the disease.Indeed,clinical and prognostic features are different from nodal and extranodal or the bone marrow(in case of plasma cell disease)counterpart.Therefore,the approach should be based on the knowledge of the peculiar behavior and natural history of disease. | Calogero Vetro Giacomo Bonanno Giorgio Giulietti Alessandra Romano Concetta Conticello Annalisa Chiarenza Paolo Spina Francesco Coppolino Rosario Cunsolo Francesco Di Raimondo | 2015 | World Journal of Gastrointestinal Endoscopy2015，7，10： | 4 |
| 7 | Early pancreatic cancer in Ig G4-related pancreatic mass:A case report显示文摘BACKGROUND IgG4-related disease can manifest diversely,including autoimmune pancreatitis and IgG4-related cholangiopathy.We are reporting a very unusual cause of pancreatic cancer triggered in a previously unknown IgG4-related disease.CASE SUMMARY A 75-year-old man was diagnosed with a 43 mm×33 mm pancreatic head tumor after consulting for abdominal pain and jaundice.A pancreaticoduodenectomy was carried out uneventfully,and the histopathology report showed an early stage of acinar-cell pancreatic cancer.The patient reconsulted on the 30th postoperative day with fever,jaundice and asthenia.Magnetic resonance cholangiopancreatography evidenced an extense bile duct stricture.A percutaneous biliary drainage proved to be ineffective,even after exchanging it with larger bore drainage.Reviewing the surgical specimen,features compatible with IgG4-related disease were observed.Consequently,empiric treatment with steroids was initiated achieving excellent results.CONCLUSION IgG4-related disease may cause chronic inflammation of the pancreas and can condition pancreatic malignancies. | Juan Glinka Francisco Calderón Martín de Santibanes Sung Ho Hyon Adrián Gadano Eduardo Mullen Melina Pol Juan Spina Eduardo de Santibanes | 2019 | World Journal of Gastrointestinal Surgery2019，11，12： | 3 |
| 8 | Stochastic collocation for device-level variability analysis in integrated photonics显示文摘We demonstrate the use of stochastic collocation to assess the performance of photonic devices under the effect of uncertainty. This approach combines high accuracy and efficiency in analyzing device variability with the ease of implementation of sampling-based methods. Its flexibility makes it suitable to be applied to a large range of photonic devices. We compare the stochastic collocation method with a Monte Carlo technique on a numerical analysis of the variability in silicon directional couplers. | Yufei Xing Domenico Spina Ang Li Tom Dhaene Wim Bogaerts | 2016 | Photonics Research2016，4，2： | 3 |
| 9 | Mechanisms and major sites of distal catheter migration in ventriculoperitoneal shunting maneuvers: A review article显示文摘A ventriculoperitoneal shunt(VPS) is a medical device used to deflect cerebrospinal fluid from cerebral ventricles to the peritoneal cavity. Since 1908, ventriculoperitoneal shunts have been considered the best option in hydrocephalus management. Manifestation related to VPS may arise anywhere whilst tunneling the VPS from the ventricle to the peritoneal cavity, but complications associated with the distal catheter are especially common and a leading cause of revision surgeries. Among the many complications associated with peritoneal shunts, migration of the catheter into other parts of the body is still common. Scrotal migration mainly takes place in children aged 4 days to 5 years. Patent processus vaginalis, formation of an inguinal hernia, and increased intraabdominal pressure are leading risk factors associated with migration of the peritoneal catheter into the scrotum. Thoracic migration of peritoneal catheters predominantly occurs in adult patients. Important mechanisms in thoracic migration include(1) iatrogenic perforation of the external or internal jugular veins by the surgeon during tunneling and(2) gradual destruction of the venous structures by the catheter due to routine extension and flexion of the neck. After entering the vessel, negative intrathoracic pressure combined with positive intraabdominal pressure aids migration into the thoracic cavity. Sharp tips or shunt types contribute to intraabdominal migration and perforation. | Ismatullah Soufiany Khalil Ahmad Hijrat Spina Soufiany Lukui Chen | 2018 | Translational Neuroscience and Clinics2018，4，2： | 2 |
| 10 | Numerical modeling of a linear photonic system for accurate and efficient time-domain simulations显示文摘In this paper, a novel modeling and simulation method for general linear, time-invariant, passive photonic devices and circuits is proposed. This technique, starting from the scattering parameters of the photonic system under study, builds a baseband equivalent state-space model that splits the optical carrier frequency and operates at baseband, thereby significantly reducing the modeling and simulation complexity without losing accuracy.Indeed, it is possible to analytically reconstruct the port signals of the photonic system under study starting from the time-domain simulation of the corresponding baseband equivalent model. However, such equivalent models are complex-valued systems and, in this scenario, the conventional passivity constraints are not applicable anymore. Hence, the passivity constraints for scattering parameters and state-space models of baseband equivalent systems are presented, which are essential for time-domain simulations. Three suitable examples demonstrate the feasibility, accuracy, and efficiency of the proposed method. | YINGHAO YE DOMENICO SPINA YUFEI XING WIM BOGAERTS TOM DHAENE | 2018 | Photonics Research2018，6，6： | 2 |
| 11 | Intermittent gastric outlet obstruction due to a gallstone migrated through a cholecysto-gastric fistula:A new variant of “Bouveret’s syndrome”显示文摘Bouveret's syndrome, defined as gastric outlet obstruction due to a large gallstone, is still one of the most dramatic biliary gallstone complications. Although new radiological and endoscopic techniques have made pre-surgical diagnosis possible in most cases and the death rate has dropped dramatically, 'one-stage surgery' (biliary surgery carried out at the same time as the removal of the gut obstruction) should be still considered as the gold standard for the treatment of gallstone ileus.In this case, partial gastric outlet obstruction resulted in an atypical and insidious clinical presentation that allowed us to perform the conventional one-stage laparatomic procedure that completely solved the problem, thus avoiding any further complications. | Dimitry Arioli Ivo Venturini Michele Masetti Elisa Romagnoli Antonella Scarcelli Pietro Ballesini Athos Borghi Alessandro Barberini Vincenzo Spina Mario De Santis Fabrizio Di Benedetto Giorgio Enrico Gerunda Maria Luisa Zeneroli | 2008 | World Journal of Gastroenterology2008，14，1： | 2 |
| 12 | Intramuscular vs intradermal route for hepatitis B booster vaccine in celiac children显示文摘AIM:To compare intradermal(ID) and intramuscular(IM) booster doses,which have been used in healthy and high risk subjects,such as healthcare workers,haemodialysis patients,human immunodeficiency virus patients,and renal transplant recipients unresponsive to initial hepatitis B vaccination,in celiac individuals.METHODS:We conducted our study on 58 celiac patients,vaccinated in the first year of life,whose blood analysis had showed the absence of protective hepatitis B virus(HBV) antibodies.All patients had received the last vaccine injection at least one year before study enrolment and they had been on a gluten free diet for at least 1 year.In all patients we randomly performed an HBV vaccine booster dose by ID or IM route.Thirty celiac patients were revaccinated with recombinant hepatitis B vaccine(Engerix B) 2 g by the ID route,while 28 celiac patients were revaccinated with Engerix B 10 g by the IM route.Four weeks after every booster dose,the anti-hepatitis B surface(HBs) antibody titer was measured by an enzyme-linked immuneadsorbent assay.We performed a maximum of three booster doses in patients with no anti-HBs antibodies after the first or the second vaccine dose.The cut off value for a negative anti-HBs antibody titer was 10 IU/L.Patients with values between 10 and 100 IU/L were considered 'low responders' while patients with an antibody titer higher than 1000 IU/L were considered 'high responders'.RESULTS:No significant difference in age,gender,duration of illness,and years of gluten intake was found between the two groups.We found a high percentage of 'responders' after the first booster dose(ID = 76.7%,IM = 78.6%) and a greater increase after the third dose(ID = 90%,IM = 96.4%) of vaccine in both groups.Moreover we found a significantly higher number of high responders(with an anti-HBs antibody titer > 1000 IU/L) in the ID(40%) than in the IM(7.1%) group,and this difference was evident after the first booster dose of vaccination(P < 0.01).No side effects were recorded in performing delivery of the vaccine by either the ID or IM route.CONCLUSION:Our study suggests that both ID and IM routes are effective and safe options to administer a booster dose of HBV vaccine in celiac patients.However the ID route seems to achieve a greater number of high responders and to have a better cost/benefit ratio. | Salvatore Leonardi Andrea Domenico Praticò Elena Lionetti Massimo Spina Giovanna Vitaliti Mario La Rosa | 2012 | World Journal of Gastroenterology2012，18，40： | 2 |
