2Mycophenolate mofetil for drug-induced vanishing bile duct syndrome显示文摘Amoxicillin/clavulanate is associated with liver injury, mostly of a cholestatic pattern. While outcomes are usually benign, progression to cirrhosis and death has been reported. The role of immunosuppressive therapy for patients with a protracted course is unclear. We report the case of an elderly patient who developed prolonged cholestasis secondary to amoxicillin/clavulanate. Vanishing bile duct syndrome was confirmed by sequential liver biopsies. The patient responded to prednisone treatment, but could not be weaned off corticosteroids, even when azathioprine was added. Complete withdrawal of both prednisone and azathioprine was possible by using mycophenolate mofetil, an inosine monophosphate dehydrogenase inhibitor. Sustained remission has been maintained for more than 3 years with low-dose mycophenolate mofetil.S Simona Jakab A Brian West Dennis M Meighan Robert S Brown Jr William B Hale 2007World Journal of Gastroenterology2007,13,45:8

4Subcurative radiation significantly increases cell proliferation, invasion, and migration of primary glioblastoma multiforme in vivo显示文摘Tumor cell proliferation, infiltration, migration, and neovascularization are known causes of treatment resistance in glioblastoma multiforme(GBM). The purpose of this study was to determine the effect of radiation on the growth characteristics of primary human GBM developed in a nude rat. Primary GBM cells grown from explanted GBM tissues were implanted orthotopically in nude rats. Tumor growth was confirmed by magnetic resonance imaging on day 77(baseline) after implantation. The rats underwent irradiation to a dose of 50 Gy delivered subcuratively on day 84 postimplantation(n = 8), or underwent no radiation(n = 8). Brain tissues were obtained on day 112(nonirradiated) or day 133(irradiated). Immunohistochemistry was performed to determine tumor cell proliferation(Ki-67) and to assess the expression of infiltration marker(matrix metalloproteinase-2, MMP-2) and cell migration marker(CD44). Tumor neovascularization was assessed by microvessel density using von-Willebrand factor(vWF) staining. Magnetic resonance imaging showed well-developed, infiltrative tumors in 11 weeks postimplantation. The proportion of Ki-67-positive cells in tumors undergoing radiation was(71 ± 15)% compared with(25 ± 12)% in the nonirradiated group(P = 0.02). The number of MMP-2-positive areas and proportion of CD44-positive cells were also high in tumors receiving radiation, indicating great invasion and infiltration. Microvessel density analysis did not show a significant difference between nonirradiated and irradiated tumors. Taken together, we found that subcurative radiation significantly increased proliferation, invasion, and migration of primary GBM. Our study provides insights into possible mechanisms of treatment resistance following radiation therapy for GBM.Adarsh Shankar Sanath Kumar Asm Iskander Nadimpalli RS Varma Branislava Janic Ana deCarvalho Tom Mikkelsen Joseph A Frank Meser M Ali Robert A Knight Stephen Brown Ali S Arbab 2014Chinese Journal of Cancer2014,33,3:5
5Multifunctional to multistage delivery systems: The evolution of nanoparticles for biomedical applications显示文摘Nanomaterials are advancing in several directions with significant progress being achieved with respect to their synthesis, functionalization and biomedical application. In this review, we will describe several classes of prototypical nanocarriers, such as liposomes, silicon particles, and gold nanoshells, in terms of their individual function as well as their synergistic use. Active and passive targeting, photothermal ablation, and drug controlled release constitute some of the crucial functions identified to achieve a medical purpose. Current limitations in targeting, slow clearance, and systemic as well as local toxicity are addressed in reference to the recent studies that attempted to comprehend and solve these issues. The demand for a more sophisticated understanding of the impact of nanomaterials on the body and of their potential immune response underlies this discussion. Combined components are then discussed in the setting of multifunctional nanocarriers, a class of drug delivery systems we envisioned, proposed, and evolved in the last 5 years. In particular, our third generation of nanocarriers, the multistage vectors, usher in the new field of nanomedicine by combining several components onto multifunctional nanocarriers characterized by emerging properties and able to achieve synergistic effects.MARTINEZ Jonathan O BROWN Brandon S QUATTROCCHI Nicoletta EVANGELOPOULOS Michael FERRARI Mauro TASCIOTTI Ennio 2012Chinese Science Bulletin2012,57,31:4

9叶面喷布铜和钙对樱桃和苹果果实品质的影响显示文摘研究了开花后单独使用氢氧化钙(30g/l)或氢氧化钙与氢氧化铜混合使用(含Cu50%的Kocide1.5g/l)对甜樱桃和苹果果实品质的影响。甜樱桃在开花后6周,苹果在开花后8周进行喷雾。单独使用氢氧化钙仅减少“金冠”苹果的果锈,而对其它所测定的品质指标无影响。铜、钙混合施用提高甜樱桃“Bing”和“Van”果实的抗裂性和硬度。这种喷雾混合物也能增强金冠苹果的果肉硬度。G S Brown 覃淑君 1998绵阳经济技术高等专科学校学报1998,15,3:3
10Patterns of genomic and phenomic diversity in wine and table grapes显示文摘Grapes are one of the most economically and culturally important crops worldwide,and they have been bred for both winemaking and fresh consumption.Here we evaluate patterns of diversity across 33 phenotypes collected over a 17-year period from 580 table and wine grape accessions that belong to one of the world’s largest grape gene banks,the grape germplasm collection of the United States Department of Agriculture.We find that phenological events throughout the growing season are correlated,and quantify the marked difference in size between table and wine grapes.By pairing publicly available historical phenotype data with genome-wide polymorphism data,we identify large effect loci controlling traits that have been targeted during domestication and breeding,including hermaphroditism,lighter skin pigmentation and muscat aroma.Breeding for larger berries in table grapes was traditionally concentrated in geographic regions where Islam predominates and alcohol was prohibited,whereas wine grapes retained the ancestral smaller size that is more desirable for winemaking in predominantly Christian regions.We uncover a novel locus with a suggestive association with berry size that harbors a signature of positive selection for larger berries.Our results suggest that religious rules concerning alcohol consumption have had a marked impact on patterns of phenomic and genomic diversity in grapes.ZoëMigicovsky Jason Sawler Kyle M Gardner Mallikarjuna K Aradhya Bernard H Prins Heidi R Schwaninger Carlos D Bustamante Edward S Buckler Gan-Yuan Zhong Patrick J Brown Sean Myles 2017Horticulture Research2017,4,1:3

17Novel biomarkers for patient stratification in colorectal cancer:A review of definitions,emerging concepts,and data显示文摘Colorectal cancer(CRC) treatment has become more personalised,incorporating a combination of the individual patient risk assessment,gene testing,and chemotherapy with surgery for optimal care.The improvement of staging with high-resolution imaging has allowed more selective treatments,optimising survival outcomes.The next step is to identify biomarkers that can inform clinicians of expected prognosis and offer the most beneficial treatment,while reducing unnecessary morbidity for the patient.The search for biomarkers in CRC has been of significant interest,with questions remaining on their impact and applicability.The study of biomarkers can be broadly divided into metabolic,molecular,micro RNA,epithelial-to-mesenchymal-transition(EMT),and imaging classes.Although numerous molecules have claimed to impact prognosis and treatment,their clinical application has been limited.Furthermore,routine testing of prognostic markers with no demonstrable influence on response to treatment is a questionable practice,as it increases cost and can adversely affect expectations of treatment.In this review we focus on recent developments and emerging biomarkers with potential utility for clinical translation in CRC.We examine and critically appraise novel imaging and molecular-based approaches; evaluate the promising array of micro RNAs,analyze metabolic profiles,and highlight key findings for biomarker potential in the EMT pathway.Manish Chand Deborah S Keller Reza Mirnezami Marc Bullock Aneel Bhangu Brendan Moran Paris P Tekkis Gina Brown Alex Mirnezami Mariana Berho 2018World Journal of Gastrointestinal Oncology2018,10,7:2

20SARS-COV-2 infection(coronavirus disease 2019)for the gastrointestinal consultant显示文摘The current pandemic due to the severe acute respiratory syndrome coronavirus 2 has caused an extreme burden for health care systems globally,and the number of cases is expected to continue to increase,at least in the immediate future.The virus is estimated to have infected more than 1.5 million individuals.The available reports suggest that gastrointestinal(GI)involvement in coronavirus disease 2019(COVID-19)is common and in some cases the GI symptoms may precede the respiratory symptoms.In addition to direct effects of severe acute respiratory syndrome coronavirus 2,the infected patients remain at risk for the complications commonly managed by gastroenterology and hepatology consultants.The most commonly reported GI manifestation of COVID-19 is diarrhea,which is reported in a third to up to more than half of the patients.Mild to moderate elevation of the liver enzymes are also common,although no case of acute liver failure has been reported so far.Many of the medications used for treatment of COVID-19 can also be associated with GI symptoms or liver injury and can be included in the differential diagnosis in these patients.Although the diagnosis of the infection is currently based on RNA analysis in respiratory samples,the available literature on fecal shedding of this virus suggests that fecal RNA testing might prove to be a useful diagnostic test.It is reasonable to delay all non-urgent endoscopic procedures during the peak of the pandemic and use additional protective equipment such as N95 respirators during endoscopy while most patients can be considered high risk for having been exposed to the virus.Kaveh Hajifathalian Srihari Mahadev Robert E Schwartz Shawn Shah Kartik Sampath Felice Schnoll-Sussman Robert S Brown Jr David Carr-Locke David E Cohen Reem Z Sharaiha 2020World Journal of Gastroenterology2020,26,14:2
