3Novel understanding of ABC transporters ABCB1/MDR/P-glycoprotein, ABCC2/MRP2, and ABCG2/BCRP in colorectal pathophysiology显示文摘AIM: To evaluate ATP-binding cassette(ABC) transporters in colonic pathophysiology as they had recently been related to colorectal cancer(CRC) development. METHODS: Literature search was conducted on Pub Med using combinations of the following terms: ABC transporters, ATP binding cassette transporter proteins, inflammatory bowel disease, ulcerative, colitis, Crohns disease, colorectal cancer, colitis, intestinal inflammation, intestinal carcinogenesis, ABCB1/P-glycoprotein(P-gp/CD243/MDR1), ABCC2/multidrug resistance protein 2(MRP2) and ABCG2/breast cancer resistance protein(BCRP), Abcb1/Mdr1 a, abcc2/Mrp2, abcg2/Bcrp, knock-out mice, tight junction, membrane lipid function. RESULTS: Recently, human studies reported thatchanges in the levels of ABC transporters were early events in the adenoma-carcinoma sequence leading to CRC. A link between ABCB1, high fat diet and gut microbes in relation to colitis was suggested by the animal studies. The finding that colitis was preceded by altered gut bacterial composition suggests that deletion of Abcb1 leads to fundamental changes of hostmicrobiota interaction. Also, high fat diet increases the frequency and severity of colitis in specific pathogenfree Abcb1 KO mice. The Abcb1 KO mice might thus serve as a model in which diet/environmental factors and microbes may be controlled and investigated in relation to intestinal inflammation. Potential molecular mechanisms include defective transport of inflammatory mediators and/or phospholipid translocation from one side to the other of the cell membrane lipid bilayer by ABC transporters affecting inflammatory response and/or function of tight junctions, phagocytosis and vesicle trafficking. Also, diet and microbes give rise to molecules which are potential substrates for the ABC transporters and which may additionally affect ABC transporter function through nuclear receptors and transcriptional regulation. Another critical role of ABCB1 was suggested by the finding that ABCB1 expression identifies a subpopulation of pro-inflammatory Th17 cells which were resistant to treatment with glucocorticoids. The evidence for the involvement of ABCC2 and ABCG2 in colonic pathophysiology was weak. CONCLUSION: ABCB1, diet, and gut microbes mutually interact in colonic inflammation, a well-known risk factor for CRC. Further insight may be translated into preventive and treatment strategies.Vibeke Andersen Katrine Svenningsen Lina Almind Knudsen Axel Kornerup Hansen Uffe Holmskov Allan Stensballe Ulla Vogel 2015World Journal of Gastroenterology2015,21,41:10

7DGGE法与常规培养法对稻田蓝细菌多态性分析结果比较显示文摘研究运用蓝细菌和硅藻16SrDNA特异引物,将晚季水稻生长后期稻田土壤中提取的总DNA进行PCR扩增后,以DGGE技术对PCR产物进行分析结果表明,14条DGGE带经克隆测序,经NCBI基因库比对得晚季水稻生长后期存在10种蓝细菌,包括4种Leptolyngbya、1种Chamaesiphon、1种Nostoc、1种Oscillatoria、2种Syne-chococcus和1种Chroococcidiopsis。同层不同位置土壤中蓝细菌种群亦有所不同,但每个取样点都有一些特有的蓝细菌种类。用常规方法对同一稻田土壤样品进行分离培养,根据蓝细菌鉴定图谱观察到类似Lyngbya、Oscillatori-a、Chroococcidiopsis及Nostoc的蓝细菌,但显微镜下无法准确分类。比较结果表明采用DGGE法比常规培养法能更准确进行蓝细菌多态性鉴定。宋铁英 林智敏 郑伟文 LOTTA Martensson ULLA Rusmussen 2005中国生态农业学报2005,13,3:4
8Polymorphisms in NF-κB,PXR,LXR,PPARγ and risk of inflammatory bowel disease显示文摘AIM:To investigate the contribution of polymorphisms in nuclear receptors to risk of inflammatory bowel disease(IBD) . METHODS:Genotypes of nuclear factor(NF) -κB(NFKB1) NFκB-94ins/del(rs28362491) ;peroxisome proliferatoractivated receptor(PPAR) -γ(PPARγ) PPARγPro12Ala(rs1801282) and C1431T(rs 3856806) ;pregnane X receptor(PXR) (NR1I2) PXR A-24381C(rs1523127) ,C8055T(2276707) ,and A7635G(rs 6785049) ;and liver X receptor(LXR) (NR1H2) LXR T-rs1405655-C and T-rs2695121-C were assessed in a Danish case-control study of 327 Crohn's disease patients,495 ulcerative colitis(UC) patients,and 779 healthy controls.Odds ratio(OR) and 95%CI were estimated by logistic regression models. RESULTS:The PXR A7635G variant,the PPARγPro12Ala and LXR T-rs2695121-C homozygous variant genotypes were associated with risk of UC(OR:1.31,95% CI:1.03-1.66,P=0.03,OR:2.30,95%CI:1.04-5.08,P=0.04,and OR:1.41,95%CI:1.00-1.98,P=0.05,respectively) compared to the corresponding homozygous wild-type genotypes.Among never smokers,PXR A7635G and the LXR T-rs1405655-C and T-rs2695121-C variant genotypes were associated with risk of IBD(OR:1.41,95%CI:1.05-1.91,P=0.02,OR:1.63,95%CI:1.21-2.20,P=0.001,and OR:2.02,95%CI:1.36-2.99,P=0.0005,respectively) compared to the respective homozygous variant genotypes.PXR A7635G(rs6785049) variant genotype was associated with a higher risk of UC diagnosis before the age of 40 years and with a higher risk of extensive disease(OR:1.34,95%CI:1.03-1.75 and OR:2.49,95%CI:1.24-5.03,respectively) . CONCLUSION:Common PXR and LXR polymorphisms may contribute to risk of IBD,especially among never smokers.Vibeke Andersen Jane Christensen Anja Ernst Bent A Jacobsen Anne Tjφnneland Henrik B Krarup Ulla Vogel 2011World Journal of Gastroenterology2011,17,2:4
9Evaluation of a Direct Rapid Immunohistochemical Test (dRIT) for Rapid Diagnosis of Rabies in Animals and Humans显示文摘Presently the gold standard diagnostic technique for rabies is the direct immunofluorescence assay ( dFA) which is very expensive and requires a high level of expertise. There is a need for more economical and user friendly tests, particularly for use in developing countries. We have established one such test called the direct rapid immunohistochemical test (dRIT) for diagnosis of rabies using brain tissue. The test is based on capture of rabies nucleoprotein (N) antigen in brain smears using a cocktail of biotinylated monoclonal antibodies specific for the N protein and color development by streptavidin peroxidase-amino ethyl carbazole and counter staining with haematoxollin. The test was done in parallel with standard FAT dFA using 400 brain samples from different animals and humans. The rabies virus N protein appears under light microscope as reddish brown particles against a light blue background. There was 100 % correlation between the results obtained by the two tests. Also, interpretation of results by dRIT was easier and only required a light microscope. To conclude, this newly developed dRIT technique promises to be a simple, cost effective diagnostic tool for rabies and will have applicability in field conditions prevalent in developing countries.Shampur Narayan Madhusudana Sundaramurthy Subha Ullas Thankappan Yajaman Belludi Ashwin 2012Virologica Sinica2012,27,5:3

11Light Triggers the miRNA-Biogenetic Inconsistency for De-etiolated Seedling Survivability in Arabidopsis thaliana显示文摘The shift of dark-grown seedlings into light causes enormous transcriptome changes followed by a dramatic developmental transition.Here,we show that microRNA(miRNA)biogenesis also undergoes regulatory changes during de-etiolation.Etiolated seedlings maintain low levels of primary miRNAs(pri-miRNAs)and miRNA processing core proteins,such as Dicer-like 1,SERRATE,and HYPONASTIC LEAVES 1,whereas during de-etiolation both pri-miRNAs and the processing components accumulate to high levels.However,the levels of most miRNAs do not notably increase in response to light.To reconcile this inconsistency,we demonstrated that an unknown suppressor decreases miRNA-processing activity and light-induced SMALL RNA DEGRADING NUCLEASE 1 shortens the half-life of several miRNAs in de-etiolated seedlings.Taken together,these data suggest a novel mechanism,miRNA-biogenetic inconsistency,which accounts for the intricacy of miRNA biogenesis during de-etiolation.This mechanism is essential for the survival of de-etiolated seedlings after long-term skotomorphogenesis and their optimal adaptation to ever-changing light conditions.Suk Won Choi Moon Young Ryu Andras Viczian Hyun Ju Jung Gu Min Kim Agustin LArce Natalia PAchkar Pablo Manavella Ulla Dolde Stephan Wenke Attila Molnar Ferenc Nagy Seok Keun Cho Seong Wook Yang 2020Molecular Plant2020,13,3:3
12rate of adverse events of gastroduodenal snare polypectomy for non-flat polyp is low: A prospective and multicenter study显示文摘AIM To evaluate the rate of adverse events(AEs) during consecutive gastric and duodenal polypectomies in several Spanish centers. METHODS Polypectomies of protruded gastric or duodenal polyps ≥ 5 mm using hot snare were prospectively included. Prophylactic measures of hemorrhage were allowed in predefined cases. AEs were defined and graded according to the lexicon recommended by the American Society for Gastrointestinal Endoscopy. Patients were followed for 48 h, one week and 1 mo after theprocedure. RESULTS308 patients were included and a single polypectomy was performed in 205. Only 36(11.7%) were on prior anticoagulant therapy. Mean polyp size was 15 ± 8.9 mm(5-60) and in 294 cases(95.4%) were located in the stomach. Hemorrhage prophylaxis was performed in 219(71.1%) patients. Nine patients presented AEs(2.9%), and 6 of them were bleeding(n = 6, 1.9%)(in 5 out of 6 AE, different types of endoscopic treatment were performed). Other 24 hemorrhagic episodes could be managed without any change in the outcome of the endoscopy and, consequently, were considered incidents. We did not find any independent risk factor of bleeding.CONCLUSION Gastroduodenal polypectomy using prophylactic measures has a rate of AEs small enough to consider this procedure a safe and effective method for polyp resection independently of the polyp size and location.Henry Córdova Lidia Argüello Carme Loras Antonio Naranjo Rodríguez Faust Riu Pons Joan B Gornals David Nicolás-Pérez Xavier Andújar Murcia Luis Hernández Santos Santolaria Carles Leal Carles Pons Enrique Pérez-Cuadrado-Robles Orlando García-Bosch Michel Papo Berger José Luis Ulla Rocha Cristina Sánchez-Montes Gloria Fernández-Esparrach 2017World Journal of Gastroenterology2017,23,47:3
13Pneumo-CT assessing response to neoadjuvant therapy in esophageal cancer: Imaging-pathological correlation显示文摘Pneumo-computed tomography (PnCT) is a technique primarily developed and used to study stenotic lesions of the esophagus, gastroesophageal junction and stom-ach for pre-surgical planning. It helps to define both upper and lower borders of neoplasms located in the aforementioned areas. It achieves maximum lumen distension with CO2 highlighting thickened areas of the esophageal wall, thus allowing an accurate quantifica-tion of their extents. Although there are other alterna-tives for distension (oral contrast agents, water and ef-fervescent granules), they may be suboptimal. Patients with locally advanced esophageal cancer have a dismal prognosis despite surgical resection. Therefore, neo-adjuvant treatment strategies using radiation therapy and chemotherapy were developed to improve sur-vival. Neoadjuvant therapy improves esophageal tumor prognosis in a substantial proportion of patients, and the use of imaging techniques is mandatory to detect their response. PnCT combined with virtual endoscopy and multiplanar reconstruction enhances morphologic details in esophageal cancer, and thus would allow animproved assessment of response to neoadjuvant treat-ment. Therefore, more information could be provided to assess the efficacy of pre-surgical treatment. We de-scribe the potential use of PnCT to assess the response to neoadjuvant therapy in esophageal cancer with an imaging pathologic correlation.Marina Ulla Ernestina Gentile Ezequiel Levy Yeyati Maria L Diez Demetrio Cavadas Ricardo D Garcia-Monaco Pablo R Ros 2013World Journal of Gastrointestinal Oncology2013,5,12:3

20Gallbladder cancer with tumor thrombus in the superior vena cava显示文摘BACKGROUND:Gastrointestinal cancers,especially pancreatobiliary cancers,are frequently associated with or are complicated by thromboembolic phenomena due to hypercoagulability and/or altered venous drainage,especially of the abdomen and lower limbs.This report describes an unusual and interesting case of gallbladder carcinoma developing a viable tumor thrombus in the superior vena cava(SVC)with resultant SVC obstruction,while on gefitinibbased anti-epidermal growth factor receptor(EGFR)therapy.METHODS:A 60-year-old woman was incidentally diagnosed to have gallbladder cancer on cholecystectomy.She had disease recurrence and received systemic chemotherapy followed by gefitinib-based anti-EGFR therapy.Subsequently,while on gefitinib-based therapy,she presented with clinical signs and symptoms suggestive of SVC thrombosis.RESULTS:A whole body PET scan revealed a metabolically active tumor thrombus in the SVC,besides other sites of metabolically active disease inclusive of the lung parenchyma, lymph nodes and abdomen.She was treated with antithrombotics and external beam radiotherapy directed to the SVC thrombus leading to symptomatic relief.She continues to survive on the day of writing this report.CONCLUSIONS:This rare complication,though theoretically possible,is unreported because of the short overall survival of advanced gallbladder cancer patients.This highlights that with the availability of better chemotherapeutic/biotherapeutic agents for increasing in the lifespan of cancer patients,we may come across such cases more frequently in the future.Sandeep Batra Dinesh Chandra Doval Ullas Batra Pandalanghat Suresh Amit Dhiman Vineet Talwar 2010Hepatobiliary & Pancreatic Diseases International2010,9,3:2
