1Predictive value of Ki67 and p53 in locally advanced rectal cancer:Correlation with thymidylate synthase and histopathological tumor regression after neoadjuvant 5-FU-based chemoradiotherapy显示文摘AIM: To investigate the predictive value of Ki67 and p53 and their correlation with thymidylate synthase (TS) gene expression in a rectal cancer patient cohort treated according to a standardized recommended neoadjuvant treatment regimen.METHODS: Formalin fixed, paraffin embedded pre-therapeutical tumor biopsies (n = 22) and post-therapeutical resection specimens (n = 40) from patients with rectal adenocarcinoma (clinical UICC stage Ⅱ/Ⅲ) receiving standardized neoadjuvant 5-fluorouracil (5-FU) based chemoradiotherapy were studied for Ki67 and p53 expression by immunohistochemistry and correlated with TS mRNA expression by quantitative TaqMan real-time PCR after laser microdissection. The results were compared with histopathological tumor regression according to a standardized semiquantitative score grading system.RESULTS: Responders (patients with high tumor regression) showed a significantly lower Ki67 expression than non-responders in the pre-therapeutical tumor biopsies (81.2% vs 16.7%; P < 0.05) as well as in the post-therapeutical resection specimens (75.8% vs 14.3%; P < 0.01). High TS mRNA expression was significantly correlated with a high Ki67 index and low TS mRNA expression was significantly correlated with a low Ki67 index in the pre-therapeutical tumor biopsies (corr. coef. = 0.46; P < 0.01) as well as in the post-therapeutical resection specimens (corr. coef. = 0.40; P < 0.05). No significant association was found between p53 and TS mRNA expression or tumor regression.CONCLUSION: Ki67 has, like TS, predictive value in rectal cancer patients after neoadjuvant 5-FU based chemoradiotherapy. The close correlation between Ki67 and TS indicates that TS is involved in active cell cycle processes.Christiane Jakob Torsten Liersch Wolfdietrich Meyer Heinz Becker Gustavo B Baretton Daniela E Aust 2008World Journal of Gastroenterology2008,14,7:29
2Reduced anoctamin 7(ANO7) expression is a strong and independent predictor of poor prognosis in prostate cancer显示文摘Objective:Anoctamin 7(ANO7)is a calcium2+-dependent chloride ion channel protein.Its expression is restricted to prostate epithelial cells.The exact function is unknown.This study aimed to analyze ANO7 expression and its clinical significance in prostate cancer(PCa).Methods:ANO7 expression was assessed by immunohistochemistry in 17,747 clinical PCa specimens.Results:ANO7 was strongly expressed in normal prostate glandular cells but often less abundant in cancer cells.ANO7 staining was interpretable in 13,594 cancer tissues and considered strong in 34.4%,moderate in 48.7%,weak in 9.3%,and negative in 7.6%.Reduced staining was tightly linked to adverse tumor features[high classical and quantitative Gleason grade,lymph node metastasis,advanced tumor stage,high Ki67 labeling index,positive surgical margin,and early biochemical recurrence(P<0.0001 each)].The univariate Cox hazard ratio for prostate-specific antigen(PSA)recurrence after prostatectomy in patients with negative vs.strong ANO7 expression was 2.98(95%confidence interval 2.61–3.38).The prognostic impact was independent of established pre-or postoperatively available parameters(P<0.0001).Analysis of annotated molecular data showed that low ANO7 expression was linked to TMPRSS2:ERG fusions(P<0.0001),elevated androgen receptor expression(P<0.0001),as well as presence of 9 of 11 chromosomal deletions(P<0.05 each).A particularly strong association of low ANO7 expression with phosphatase and tensin homolog(PTEN)deletion may indicate a functional relationship with the PTEN/AKT pathway.Conclusions:These data identify reduced ANO7 protein expression as a strong and independent predictor of poor prognosis in PCa.ANO7 measurement,either alone or in combination,might provide clinically useful prognostic information in PCa.Andreas Marx Lena Koopmann Doris Hoflmayer Franziska Büscheck Claudia Hube-Magg Stefan Steurer Till Eichenauer Till S.Clauditz Waldemar Wilczak Ronald Simon Guido Sauter Jakob R.Izbicki Hartwig Huland Hans Heinzer Markus Graefen Alexander Haese Thorsten Schlomm Christian Bernreuther Patrick Lebok Sarah Bonk 2021Cancer Biology & Medicine2021,18,1:3
3Reduction and carburization of iron oxides for Fischer–Tropsch synthesis显示文摘The activation of iron oxide Fischer–Tropsch Synthesis(FTS) catalysts was investigated during pretreatment: reduction in hydrogen followed by carburization in either CO or syngas mixture, or simultaneously reduction and carburization in syngas. A combination of different complementary in situ techniques was used to gain insight into the behavior of Fe-based FTS catalysts during activation. In situ XRD was used to identify the crystalline structures present during both reduction in hydrogen and carburization. An increase in reduction rate was established when increasing the temperature. A complete reduction was demonstrated in the ETEM and a grain size dependency was proven, i.e. bigger grains need higher temperature in order to reduce. XPS and XAS both indicate the formation of a small amount of carbonaceous species at the surface of the bulk metallic iron during carburization.Monia Runge Nielsen Asger Barkholt Moss Anton Simon Bjrnlund Xi Liu Axel Knop-Gericke Alexander YuKlyushin Jan-Dierk Grunwaldt Thomas LSheppard Dmitry EDoronkin Anna Zimina Thomas Eric Lyck Smitshuysen Christian Danvad Damsgaard Jakob Birkedal Wagner Thomas Willum Hansen 2020Journal of Energy Chemistry2020,29,12:2

6Periprocedural complications and one-year outcomes after catheter ablation for treatment of atrial fibrillation in elderly patients:a nationwide Danish cohort study显示文摘OBJECTIVES To investigate complications within 30-days following first-time ablation for atrial fibrillation(AF),including a composite of cardiac tamponade,hematoma requiring intervention,stroke or death,in patients≥75 years of age,compared to pa-tients aged 65−74 years.In addition,one-year all-cause mortality and AF relapse were compared.METHODS&RESULTS All patients receiving their first catheter ablation for AF between 2012 and 2016 were identified us-ing Danish nationwide registries.Patients aged 65−74 years served as the reference group for patients≥75 years.Relapse of AF within one year was defined as cardioversion following a three-month blanking period,re-ablation or confirmed relapse within follow-up.The composite complication outcome did not differ between the two age groups,with 39/1554(2.8%)in patients 65−74 years of age,versus 5/199(2.5%)in older patients(adjusted HR=0.94),95%CI:0.37−2.39,P=0.896).Patients≥75 years or older had no increased hazard of death within 30 days after the procedure,with an incidence of 3/1554(0.2%)in younger pa-tients and 2/199(1.0%)in patients≥75 years of age(adjusted HR=4.71,95%CI:0.78−28.40,P=0.091).There was no difference in relapse of AF after one year between age groups(≥75 years adjusted HR=1.00,95%CI:0.78-1.26,P=0.969).CONCLUSION In patients≥75 years of age selected for catheter ablation for AF,the incidence of periprocedural complica-tions,as well as one-year freedom from AF showed no statistical difference,when compared to patients 65−74 years of age.Jesper Nielsen Kristian Hay Kragholm Sofie Brix Christensen Arne Johannessen Christian Torp-Pedersen Steen Buus Kristiansen Peter Karl Jacobsen Peter Steen Hansen Mogens Stig Djurhus Christoffer Polcwiartek Peter Søgaard Anna Margrethe Thøgersen Uffe Jakob Ortved Gang Ole Dan Jørgensen Filip Lyng Lindgren Sam Riahi 2021Journal of Geriatric Cardiology2021,18,11:1

15Simulator Coupled with Distributed Co-Simulation Protocol for Automated Driving Tests显示文摘To meet the challenges in software testing for automated vehicles,such as increasing system complexity and an infinite number of operating scenarios,new simulation methods must be developed.Closed-loop simulations for automated driving(AD)require highly complex simulation models for multiple controlled vehicles with their perception systems as well as their surrounding context.For the realization of such models,different simulation domains must be coupled with co-simulation.However,widely supported model integration standards such as functional mock-up interface(FMI)lack native support for distributed platforms,which is a key feature for AD due to the computational intensity and platform exclusivity of certain models.The newer FMI companion standard distributed co-simulation protocol(DCP)introduces platform coupling but must still be used in conjunction with AD co-simulations.As part of an assessment framework for AD,this paper presents a DCP compliant implementation of an interoperable interface between a 3D environment and vehicle simulator and a co-simulation platform.A universal Python wrapper is implemented and connected to the simulator to allow its control as a DCP slave.A C-code-based interface enables the co-simulation platform to act as a DCP master and to realize cross-platform data exchange and time synchronization of the environment simulation with other integrated models.A model-in-the-loop use case is performed with the traffic simulator CARLA running on a Linux machine connected to the co-simulation master xMOD on a Windows computer via DCP.Several virtual vehicles are successfully controlled by cooperative adaptive cruise controllers executed outside of CARLA.The standard compliance of the implementation is verified by exemplary connection to prototypic DCP solutions from 3rd party vendors.This exemplary application demonstrates the benefits of DCP compliant tool coupling for AD simulation with increased tool interoperability,reuse potential,and performance.Max-Arno Meyer Lina Sauter Christian Granrath Hassen Hadj-Amor Jakob Andert 2021Automotive Innovation2021,4,4:1
