3Toll-like receptor 4 and NOD2/CARD15 mutations in Hungarian patients with Crohn's disease: Phenotype-genotype correlations显示文摘AIM: To determine common NOD2/CARD15 mutations and TLR4 D299G polymorphism in Hungarian patients with CD.METHODS: A total of 527 unrelated patients with CD (male/female: 265/262, age: 37.1 (SD 7.6) years) and 200 healthy subjects were included. DNA was screened for possible NOD2/CARD15 mutations by denaturing highperformance liquid chromatography (confirmed by direct sequencing). TLR4 D299G was tested by PCR-RFLP.RESULTS: NOD2/CARD15 mutations were found in 185patients (35.1%) and in 33 controls (16.5%, P<0.0001).SNP8/R702W (10.8% vs 6%, P = 0.02), SNP13/3020insC (19.4% vs 5%, P<0.0001) and exon4 R703C (2.1% vs 0%, P = 0.02) mutations were more frequent in CD, while the frequency of SNP12/G908R was not increased. The frequency of TLR4 D299G was not different (CD: 9.9% vscontrols: 12.0%). Variant NOD2/CARD15 allele was associated with an increased risk for CD (ORhet = 1.71,95%CI = 1.12-2.6, P= 0.0001, ORtwo-riskalleles = 25.2,95%CI = 4.37- , P<0.0001), early disease onset (carrier:26.4 years vs non-carrier: 29.8 years, P = 0.0006), ileal disease (81.9% vs 69.5%, OR = 1.99, 95%CI = 1.29-3.08,P = 0.02, presence of NOD2/CARD15 and TLR4: 86.7% vs64.8%), stricturing behavior (OR = 1.69, 95%CI = 1.13-2.55,P = 0.026) and increased need for resection (OR=1.71,95%CI: 1.13-2.62, P= 0.01), but not with duration, extraintestinal manifestations, familial disease or smoking. TLR4exhibited a modifier effect: age of onset in wt/TLR4 D299G carriers: 27.4 years vs NOD2mut/TLR D299G: 23 years (P= 0.06), in NOD2mut/wt: 26.7 years.CONCLUSION: These results confirm that variant NOD2/CARD15 (R702W, R703C and 3020insC) alleles are associated with earlier disease onset, ileal disease,stricturing disease behavior in Hungarian CD patients. In contrast, although the frequency of TLR4 D299G polymorphism was not different from controls, NOD2/TLR4mutation carriers tended to present at earlier age.Peter Laszlo Lakatos Laszlo Lakatos Ferenc Szalay Claudia Willheim-Polli Christoph (O|¨)sterreicher Zsolt Tulassay Tamas Molnar Walter Reinisch Janos Papp Gyula Mozsik Hungarian IBD Study Group Peter Ferenci 2005World Journal of Gastroenterology2005,11,10:14

7Update on surgical treatment of pancreatic neuroendocrine neoplasms显示文摘Pancreatic neuroendocrine neoplasms(PNENs) are rare and account for only 2%-4% of all pancreatic neoplasms. All PNENs are potential(neurendocrine tumors PNETs) or overt(neuroendocrine carcinomas PNECs) malignant,but a subset of PNETs is low-risk. Even in case of low-risk PNETs surgical resection is frequently required to treat hormone-related symptoms and to obtain an appropriate pathological diagnosis. Low-risk PNETs in the body and the tail are ideal for minimallyinvasive approaches which should be tailored to the individual patient. Generally,surgeons must aim for parenchyma sparing in these cases. In high-risk and malignant PNENs,indications for tumor resection are much wider than for pancreatic adenocarcinoma,in many cases due to the relatively benign tumor biology. Thus,patients with locally advanced and metastatic PNETs may benefit from extensive resection. In experienced hands,even multi-organ resections are accomplished with acceptable perioperative morbidity and mortality rates and are associated with excellent long term survival. However,poorly differentiated neoplasms with high proliferation rates are associated with a dismal prognosis and may frequently only be treated with chemotherapy. The evidence on surgical treatment of PNENs stems from reviews of mostly singlecenter series and some analyses of nation-wide tumor registries. No randomized trial has been performed to compare surgical and non-surgical therapies in potentially resectable PNEN. Though such a trial would principally be desirable,ethical considerations and the heterogeneity of PNENs preclude realization of such a study. In the current review,we summarize recent advances in the surgical treatment of PNENs.Jan G D’Haese Chiara Tosolini Güralp O Ceyhan Bo Kong Irene Esposito Christoph W Michalski J?rg Kleeff 2014World Journal of Gastroenterology2014,20,38:4
8Solid-pseudopapillary tumor of the pancreatic tail显示文摘We report a case of the rare solid-pseudopapillary tumor of the pancreas. In contrast to other pancreatic tumors,the solid-pseudopapillary tumor has a favorable prognosis.The 60-year-old female patient we report on here was treated by left pancreatic resection combined with splenectomy for a non-metastasizing tumor of the pancreas. A solid-pseudopapillary tumor was found on histology. The patient had no signs of metastases at present.Since a microscopically invasive tumor growth is assumed,oncologically curative resection should be preferred vs the less radical enucleation. The rare solid-pseudopapillary tumor of the pancreas has a good prognosis after successful oncological resection.Frank Eder Hans-Ulrich Schulz Christoph R(o|¨)cken Hans Lippert 2005World Journal of Gastroenterology2005,11,26:4
9The Importance of Heparan Sulfate in Herpesvirus Infection显示文摘Herpes simplex virus type-1 (HSV-1) is one of many pathogens that use the cell surface glycosaminoglycan heparan sulfate as a receptor. Heparan sulfate is highly expressed on the surface and extracellular matrix of virtually all cell types making it an ideal receptor. Heparan sulfate interacts with HSV-1 envelope glycoproteins gB and gC during the initial attachment step during HSV-1 entry. In addition,a modified form of heparan sulfate,known as 3-O-sulfated heparan sulfate,interacts with HSV-1 gD to induce fusion between the viral envelope and host cell membrane. The 3-O-sulfation of heparan sulfate is a rare modification which occurs during the biosynthesis of heparan sulfate that is carried out by a family of enzymes known as 3-O-sulfotransferases. Due to its involvement in multiple steps of the infection process,heparan sulfate has been a prime target for the development of agents to inhibit HSV entry. Understanding how heparan sulfate functions during HSV-1 infection may not only be critical for inhibiting infection by this virus,but it may also be crucial in the fight against many other pathogens as well.Christopher D.

11Optimization and kinetic studies for enzymatic hydrolysis and fermentation of colocynthis vulgaris Shrad seeds shell for bioethanol production显示文摘The key process parameters for the hydrolysis and fermentation of Colocynthis vulgaris Shrad seeds shell(CVSSS)were optimized using the Box-Behnken Design(BBD)of Response Surface Methodology(RSM).Kinetic study was also carried out.The proximate analysis of the CVSSS was done by the method of the Association of Organic and Applied Chemistry(AOAC).Enzymatic hydrolysis was experimented by using Aspergillus Niger as a crude enzyme isolated from soil at sawdust dump site and screened for cellulosic activities.Factors that affected the hydrolysis of the CVSSS were screened by using the Greco-Latin square design of experiment.However,for Saccharomyces cerevisiae,factors that affected the fermentation of the CVSSS were screened by using the same Greco-Latin square design of experiment.Meanwhile,the result of the proximate analysis revealed that the CVSSS had 73.54%cellulose which could be converted to bioethanol.It was established that temperature,pH and time had significant effect on hydrolysis,while the optimum results were obtained at 46.8℃,3.32 d,5.68 and 59.87%for temperature,time,pH and glucose yield,respectively.Temperature,yeast dosage,pH and time had significant effect on fermentation,while the optimum results from optimization were found to be 33.58℃,7.0,3.55 d,1.65 g per 50 mL and 25.6%for temperature,pH,time,yeast dosage and ethanol yield,respectively.The kinetics of both the enzymatic hydrolysis and fermentation agreed with the Michealis-Menten kinetic model with the correlation coefficients(R^(2))of 0.9708 and 0.8773,respectively.However,from the error analysis,the experimental and predicted values had a very good relationship as described by Michaelis-Menten model.Igwilo Christopher Nnaemeka Egbuna Samuel O Onoh Maxwell I Asadu OChristain Onyekwulu Chinelo S 2021Journal of Bioresources and Bioproducts2021,6,1:3

17Acute exacerbation of autoimmune hepatitis induced by Twinrix显示文摘We report on a 26-year-old man who presented with severe jaundice and elevated serum liver enzyme activities after having received a dose of Twinrix(○R). In his past medical history, jaundice or abnormal liver function tests were never recorded. Following admission, an elevated immunoglobulin G level and antinuclear antibodies at a titer of 320 with a homogenous pattern were found. Histology of a liver biopsy showed marked bridging liver fibrosis and a chronic inflammation, compatible with autoimmune hepatitis. Treatment was started with budesonide and ursodeoxycholic acid,and led to complete normalization of the pathological liver function tests. We believe that Twinrix(○R) led to an acute exacerbation of an unrecognized autoimmune hepatitis in our patient. The pathogenesis remains to be clarified. It is tempting to speculate that inactivated hepatitis A virus and/or recombinant surface antigen of the hepatitis B virus -as seen in patients with chronic hepatitis C and unrecognized autoimmune hepatitis who were treated with interferon alpha-might have been responsible for disease exacerbation.Antal Csepregi Gerhard Treiber Christoph R(o|¨)cken Peter Malfertheiner 2005World Journal of Gastroenterology2005,11,26:2
