| 1 | Alternatives for large-scale production of cultured beef: A review显示文摘Cultured beef is a method where stem cells from skeletal muscle of cows are cultured in vitro to gain edible muscle tissue. For large-scale production of cultured beef, the culture technique needs to become more efficient than today's 2-dimensional(2D) standard technique that was used to make the first cultured hamburger. Options for efficient large-scale production of stem cells are to culture cells on microcarriers, either in suspension or in a packed bed bioreactor, or to culture aggregated cells in suspension. We discuss the pros and cons of these systems as well as the possibilities to use the systems for tissue culture. Either of the production systems needs to be optimized to achieve an efficient production of cultured beef. It is anticipated that the optimization of large-scale cell culture as performed for other stem cells can be translated into successful protocols for bovine satellite cells resulting in resource and cost efficient cultured beef. | Matilda S M Moritz Sanne E L Verbruggen Mark J Post | 2015 | Journal of Integrative Agriculture2015，14，2： | 7 |
| 2 | INT-767 improves histopathological features in a dietinduced ob/ob mouse model of biopsy-confirmed nonalcoholic steatohepatitis显示文摘AIM To characterize the efficacy of the dual FXR/TGR5 receptor agonist INT-767 upon histological endpoints in a rodent model of diet-induced and biopsy-confirmed non-alcoholic steatohepatitis(NASH).METHODS The effects of INT-767 on histological features of NASH were assessed in two studies using Lep^(ob/ob)(ob/ob) NASH mice fed the AMLN diet(high fat with transfat, cholesterol and fructose). In a proof-of-conceptstudy, Lep^(ob/ob)(ob/ob) NASH mice were first dosed with INT-767(3 or 10 mg/kg for 8 wk). A second ob/ob NASH study compared INT-767(3 and 10 mg/kg) to obeticholic acid(OCA)(10 or 30 mg/kg; 16 wk). Primary histological endpoints included qualitative and quantitative assessments of NASH. Other metabolic and plasma endpoints were also assessed. A comparative assessment of INT-767 and OCA effects on drug distribution and hepatic gene expression was performed in C57 Bl/6 mice on standard chow. C57 Bl/6 mice were orally dosed with INT-767 or OCA(1-30 mg/kg) for 2 wk, and expression levels of candidate genes were assessed by RNA sequencing and tissue drug levels were measured by liquid chromatography tandem-mass spectrometry.RESULTS INT-767 dose-dependently(3 and 10 mg/kg, PO, QD, 8 wk) improved qualitative morphometric scores on steatohepatitis severity, inflammatory infiltrates and fibrosis stage. Quantitative morphometric analyses revealed that INT-767 reduced parenchymal collagen area, collagen fiber density, inflammation(assessed by Galectin-3 immunohistochemistry) and hepatocyte lipid droplet area following INT-767 treatment. In a comparative study(16 wk), the FXR agonists OCA(10 and 30 mg/kg) and INT-767(3 and 10 mg/kg) both improved NASH histopathology, with INT-767 exerting greater therapeutic potency and efficacy than OCA. Mechanistic studies suggest that both drugs accumulate similarly within the liver and ileum, however, the effects of INT-767 may be driven by enhanced hepatic, but not ileal, FXR function. CONCLUSION These findings confirm the potential utility of FXR and dual FXR/TGR5 activation as disease intervention strategies in NASH. | Jonathan D Roth Michael Feigh Sanne S Veidal Louise KD Fensholdt Kristoffer T Rigbolt Henrik H Hansen Li C Chen Mathieu Petitjean Weslyn Friley Niels Vrang Jacob Jelsing Mark Young | 2018 | World Journal of Gastroenterology2018，24，2： | 7 |
| 3 | Metabolic and hepatic effects of liraglutide,obeticholic acid and elafibranor in diet-induced obese mouse models of biopsy-confirmed nonalcoholic steatohepatitis显示文摘AIM To evaluate the pharmacodynamics of compounds in clinical development for nonalcoholic steatohepatitis(NASH) in obese mouse models of biopsy-confirmedNASH.METHODS Male wild-type C57 BL/6 J mice(DIO-NASH) and Lep^(ob/ob)(ob/ob-NASH) mice were fed a diet high in trans-fat(40%), fructose(20%) and cholesterol(2%) for 30 and 21 wk, respectively. Prior to treatment, all mice underwent liver biopsy for confirmation and stratification of liver steatosis and fibrosis, using the nonalcoholic fatty liver disease activity score(NAS) and fibrosis staging system. The mice were kept on the diet and received vehicle, liraglutide(0.2 mg/kg, SC, BID), obeticholic acid(OCA, 30 mg/kg PO, QD), or elafibranor(30 mg/kg PO, QD) for eight weeks. Within-subject comparisons were performed on changes in steatosis, inflammation, ballooning degeneration, and fibrosis scores. In addition, compound effects were evaluated by quantitative liver histology, including percent fractional area of liver fat, galectin-3, and collagen 1 a1.RESULTS Liraglutide and elafibranor, but not OCA, reduced body weight in both models. Liraglutide improved steatosis scores in DIO-NASH mice only. Elafibranor and OCA reduced histopathological scores of hepatic steatosis and inflammation in both models, but only elafibranor reduced fibrosis severity. Liraglutide and OCA reduced total liver fat, collagen 1 a1, and galectin-3 content, driven by significant reductions in liver weight. The individual drug effects on NASH histological endpoints were supported by global gene expression(RNA sequencing) and liver lipid biochemistry.CONCLUSION DIO-NASH and ob/ob-NASH mouse models show distinct treatment effects of liraglutide, OCA, and elafibranor, being in general agreement with corresponding findings in clinical trials for NASH. The present data therefore further supports the clinical translatability and utility of DIO-NASH and ob/ob-NASH mouse models of NASH for probing the therapeutic efficacy of compounds in preclinical drug development for NASH. | Kirstine S Tolbol Maria NB Kristiansen Henrik H Hansen Sanne S Veidal Kristoffer TG Rigbolt Matthew P Gillum Jacob Jelsing Niels Vrang Michael Feigh | 2018 | World Journal of Gastroenterology2018，24，2： | 5 |
| 4 | Pancreatitis and pancreatic cancer:A case of the chicken or the egg显示文摘Acute pancreatitis(AP),chronic pancreatitis(CP)and pancreatic cancer are three distinct pancreatic diseases with different prognoses and treatment options.However,it may be difficult to differentiate between benign and malignant disease.AP may be a first symptom of pancreatic cancer,particularly in patients between the ages of 56 and 75 with presumed idiopathic AP who had a concomitant diagnosis of new-onset diabetes mellitus or patients who present with CP at diagnosis of AP.In these patients,additional imaging is warranted,preferably by endoscopic ultrasonography.CP may lead to pancreatic cancer through oncogenic mutations,mostly in patients with hereditary CP,and in patients in whom risk factors for pancreatic cancer(e.g.,nicotine and alcohol abuse)are also present.Patients with PRSS1-mediated CP and patients with a history of autosomal dominant hereditary CP without known genetic mutations may be considered for surveillance for pancreatic cancer.Pancreatic inflammation may mimic pancreatic cancer by appearing as a focal mass-forming lesion on imaging.Differentiation between the above mentioned benign and malignant disease may be facilitated by specific features like the duct-penetrating sign and the duct-to-parenchyma ratio.Research efforts are aimed towards developing a superior discriminant between pancreatitis and pancreatic cancer in the form of imaging modalities or biomarkers.This may aid clinicians in timely diagnosing pancreatic cancer in a potentially curable stage. | Devica S Umans Sanne A Hoogenboom Noor J Sissingh Selma J Lekkerkerker Robert C Verdonk Jeanin E van Hooft | 2021 | World Journal of Gastroenterology2021，27，23： | 5 |
| 5 | Towards a standard diet-induced and biopsy-confirmed mouse model of non-alcoholic steatohepatitis: Impact of dietary fat source显示文摘BACKGROUND The trans-fat containing AMLN(amylin liver non-alcoholic steatohepatitis,NASH)diet has been extensively validated in C57BL/6J mice with or without the Lep^ob/Lep^ob(ob/ob)mutation in the leptin gene for reliably inducing metabolic and liver histopathological changes recapitulating hallmarks of NASH.Due to a recent ban on trans-fats as food additive,there is a marked need for developing a new diet capable of promoting a compatible level of disease in ob/ob and C57BL/6J mice.AIM To develop a biopsy-confirmed mouse model of NASH based on an obesogenic diet with trans-fat substituted by saturated fat.METHODS Male ob/ob mice were fed AMLN diet or a modified AMLN diet with trans-fat(Primex shortening)substituted by equivalent amounts of palm oil[Gubra amylin NASH,(GAN)diet]for 8,12 and 16 wk.C57BL/6J mice were fed the same diets for 28 wk.AMLN and GAN diets had similar caloric content(40%fat kcal),fructose(22%)and cholesterol(2%)level.RESULTS The GAN diet was more obesogenic compared to the AMLN diet and impaired glucose tolerance.Biopsy-confirmed steatosis,lobular inflammation,hepatocyte ballooning,fibrotic liver lesions and hepatic transcriptome changes were similar in ob/ob mice fed the GAN or AMLN diet.C57BL/6J mice developed a mild to moderate fibrotic NASH phenotype when fed the same diets.CONCLUSION Substitution of Primex with palm oil promotes a similar phenotype of biopsyconfirmed NASH in ob/ob and C57BL/6J mice,making GAN diet-induced obese mouse models suitable for characterizing novel NASH treatments. | Michelle L Boland Denise Oro Kirstine S T■lb■l Sebastian T Thrane Jens Christian Nielsen Taylor S Cohen David E Tabor Fiona Fernandes Andrey Tovchigrechko Sanne S Veidal Paul Warrener Bret R Sellman Jacob Jelsing Michael Feigh Niels Vrang James L Trevaskis Henrik H Hansen | 2019 | World Journal of Gastroenterology2019，25，33： | 3 |
| 6 | Quality of life after laparoscopic and open colorectal surgery: A systematic review显示文摘This study was a systematic review of the available evidence on quality of life in patients after laparoscopic or open colorectal surgery. A systematic review was performed of all randomized clinical trials (RCTs) that compared laparoscopic with open colorectal surgery. Study selection, quality assessment and data extraction were carried out independently by two reviewers. Primary endpoint was quality of life after laparoscopic and open colorectal surgery, as assessed by validated questionnaires. The search resulted in nine RCTs that included 2263 patients. Shortand long-term results of these RCTs were described in 13 articles. Postoperative follow-up ranged from 2 d to 6.7 years. Due to clinical heterogeneity, no meta-analysis could be conducted. Four RCTs did not show any difference in quality of life between laparoscopic or open colorectal surgery. The remaining five studies reported a better quality of life in favor of the laparoscopic group on a few quality of life scales at time points ranging from 1 wk to 2 years after surgery. In conclusion, based on presently available high-level evidence, this systematic review showed no clinically relevant differences in postoperative quality of life between laparoscopic and open colorectal surgery. | Sanne AL Bartels Malaika S Vlug Dirk T Ubbink Willem A Bemelman | 2010 | World Journal of Gastroenterology2010，16，40： | 3 |
