| 1 | Genome-wide MicroRNA Expression Profiles in COPD: Early Predictors for Cancer Development显示文摘Chronic obstructive pulmonary disease(COPD) significantly increases the risk of developing cancer. Biomarker studies frequently follow a case-control set-up in which patients diagnosed with a disease are compared to controls. Longitudinal cohort studies such as the COPD-centered German COPD and SYstemic consequences-COmorbidities NETwork(COSYCONET) study provide the patient and biomaterial base for discovering predictive molecular markers. We asked whether microRNA(miRNA) profiles in blood collected from COPD patients prior to a tumor diagnosis could support an early diagnosis of tumor development independent of the tumor type. From 2741 participants of COSYCONET diagnosed with COPD, we selected 534 individuals including 33 patients who developed cancer during the follow-up period of 54 months and 501 patients who did not develop cancer, but had similar age, gender and smoking history. Genome-wide miRNA profiles were generated and evaluated using machine learning techniques. For patients developing cancer we identified nine miRNAs with significantly decreased abundance(two-tailed unpaired t-test adjusted for multiple testing P < 0.05), including members of the miR-320 family. The identified mi RNAs regulate different cancer-related pathways including the MAPK pathway(P = 2.3 x 10^(-5)). We also observed the impact of confounding factors on the generated miRNA profiles, underlining the value of our matched analysis. For selected miRNAs, qRT-PCR analysis was applied to validate the results. In conclusion, we identified several miRNAs in blood of COPD patients, which could serve as candidates for biomarkers to help identify COPD patients at risk of developing cancer. | Andreas Keller Tobias Fehlmann Nicole Ludwig Mustafa Kahraman Thomas Laufer Christina Backes Claus Vogelmeier Caroline Diener Frank Biertz Christian Herr Rudolf A.

| 4 | The chemokine receptor CCR7 is a promising target for rheumatoid arthritis therapy显示文摘The chemokine receptor CCR7 and its ligands CCL19 and CCL21 guide the homing and positioning of dendritic and T cells in lymphoid organs,thereby contributing to several aspects of adaptive immunity and immune tolerance.In the present study,we investigated the role of CCR7 in the pathogenesis of collagen-induced arthritis(CIA).By using a novel anti-human CCR7 antibody and humanized CCR7 mice,we evaluated CCR7 as a target in this autoimmune model of rheumatoid arthritis(RA).Ccr7-deficient mice were completely resistant to CIA and presented severely impaired antibody responses to collagen II(CII).Selective CCR7 expression on dendritic cells restored arthritis severity and anti-CII antibody titers.Prophylactic and therapeutic treatment of humanized CCR7 mice with anti-human CCR7 mAb 8H3-16A12 led to complete resistance to CIA and halted CIA progression,respectively.Our data demonstrate that CCR7 signaling is essential for the induction of CIA and identify CCR7 as a potential therapeutic target in RA. | Georgios L.Moschovakis Anja Bubke Michaela Friedrichsen Jasmin Ristenpart Jaap Willem Back Christine S.Falk Elisabeth Kremmer Reinhold Forster | 2019 | Cellular & Molecular Immunology2019,16,10: | 3 |
| 5 | Robotic Intra-Operative Ultrasound:Virtual Environments and Parallel Systems显示文摘Robotic intra-operative ultrasound has the potential to improve the conventional practice of diagnosis and procedure guidance that are currently performed manually.Working towards automatic or semi-automatic ultrasound,being able to define ultrasound views and the corresponding probe poses via intelligent approaches become crucial.Based on the concept of parallel system which incorporates the ingredients of artificial systems,computational experiments,and parallel execution,this paper utilized a recent developed robotic trans-esophageal ultrasound system as the study object to explore the method for developing the corresponding virtual environments and present the potential applications of such systems.The proposed virtual system includes the use of 3 D slicer as the main workspace and graphic user interface(GUI),Matlab engine to provide robotic control algorithms and customized functions,and PLUS(Public software Library for Ultra Sound imaging research)toolkit to generate simulated ultrasound images.Detailed implementation methods were presented and the proposed features of the system were explained.Based on this virtual system,example uses and case studies were presented to demonstrate its capabilities when used together with the physical TEE robot.This includes standard view definition and customized view optimization for pre-planning and navigation,as well as robotic control algorithm evaluations to facilitate real-time automatic probe pose adjustments.To conclude,the proposed virtual system would be a powerful tool to facilitate the further developments and clinical uses of the robotic intra-operative ultrasound systems. | Shuangyi Wang James Housden Tianxiang Bai Hongbin Liu Junghwan Back Davinder Singh Kawal Rhode Zeng-Guang Hou Fei-Yue Wang | 2021 | IEEE/CAA Journal of Automatica Sinica2021,8,5: | 3 |
| 6 | 有为腹的 CT 的非线性的适应过滤器的申请的放射剂量减小显示文摘 AIM:To evaluate the effect of non-linear adaptive filters (NLAF) on abdominal computed tomography (CT) images acquired at different radiation dose levels.METHODS:Nineteen patients (mean age 61.6 ± 7.9 years,M:F=8:11) gave informed consent for an Institutional Review Board approved prospective study involving acquisition of 4 additional image series (200,150,100,50 mAs and 120 kVp) on a 64 slice multidetector row CT scanner over an identical 10 cm length in the abdomen.The CT images acquired at 150,100 and 50 mAs were processed with the NLAF.Two radiologists reviewed unprocessed and processed images for image quality in a blinded randomized manner.CT dose index volume,dose length product,patient weight,transverse diameters,objective noise and CT numbers wererecorded.Data were analyzed using Analysis of Variance and Wilcoxon signed rank test.RESULTS:Of the 31 lesions detected in abdominal CT images,28 lesions were less than 1 cm in size.Subjective image noise was graded as unacceptable in unprocessed images at 50 and 100 mAs,and in NLAF processed images at 50 mAs only.In NLAF processed images,objective image noise was decreased by 21% (14.4 ± 4/18.2 ± 4.9) at 150 mAs,28.3% (15.7 ± 5.6/21.9 ± 4) at 100 mAs and by 39.4% (18.8 ± 9/30.4 ± 9.2) at 50 mAs compared to unprocessed images acquired at respective radiation dose levels.At 100 mAs the visibility of smaller structures improved from suboptimal in unprocessed images to excellent in NLAF processed images,whereas diagnostic confidence was respectively improved from probably confident to fully confident.CONCLUSION:NLAF lowers image noise,improves the visibility of small structures and maintains lesion conspicuity at down to 100 mAs for abdominal CT. | Sarabjeet Singh Mannudeep K Kalra Mi Kim Sung Anni Back Michael A Blake | 2012 | World Journal of Radiology2012,4,1: | 3 |
| 7 | Chronic antiepileptic drug use and functional network efficiency: A functional magnetic resonance imaging study显示文摘AIM To increase our insight in the neuronal mechanisms underlying cognitive side-effects of antiepileptic drug(AED) treatment.METHODS The relation between functional magnetic resonance-acquired brain network measures, AED use, and cognitive function was investigated. Three groups of patients with epilepsy with a different risk profile for developing cognitive side effects were included: A 'low risk' category(lamotrigine or levetiracetam, n=16), an 'intermediate risk' category(carbamazepine, oxcarbazepine, phenytoin, or valproate, n=34) and a 'high risk' category(topiramate, n=5). Brain connectivity was assessed using resting state functional magnetic resonance imaging and graph theoretical network analysis. The Computerized Visual Searching Task was used to measure central information processing speed, a common cognitive side effect of AED treatment. RESULTS Central information processing speed was lower in patients taking AEDs from the intermediate and high risk categories, compared with patients from the low risk category. The effect of risk category on global efficiency was significant(P < 0.05, ANCOVA), with a significantly higher global efficiency for patient from the low category compared with the high risk category(P < 0.05, post-hoc test). Risk category had no significant effect on the clustering coefficient(ANCOVA, P > 0.2). Also no significant associations between information processing speed and global efficiency or the clustering coefficient(linear regression analysis, P > 0.15) were observed. CONCLUSION Only the four patients taking topiramate show aberrant network measures, suggesting that alterations in functional brain network organization may be only subtle and measureable in patients with more severe cognitive side effects. | Tamar M van Veenendaal Dominique M IJff Albert P Aldenkamp Richard H C Lazeron Paul A M Hofman Anton J A de Louw Walter H Backes Jacobus F A Jansen | 2017 | World Journal of Radiology2017,9,6: | 2 |
| 8 | Application of powdered activated carbon coating to fabrics in a hybrid filter to enhance mercury removal显示文摘Elemental mercury(Hg0) is predominant constituent of flue gas emitted from coal-fired power plants. Adsorption has been considered the best available technology for removal of Hg0 from flue gas. However, adsorbent injection increases the amount of ash generated. In the present study, powdered activated carbon(PAC) was coated on polytetrafluoroethylene/glass fiber filters to increase Hg0 removal while concurrently reducing the amount of ash generated. The optimal PAC coating rate was determined in laboratory experiments to ensure better Hg0 removal with low pressure drop. When PAC of particle size less than 45 μm was used, and the areal density was 50 g/m2, the pressure drop remained under 30 Pa while the Hg0 removal efficiency increased to 15.8% from4.3%. The Hg0 removal efficiency also increased with decrease in filtration velocity. The optimal PAC coating rate was applied on a hybrid filter(HF), which was combined with a bag filter and an electrostatic precipitator in a single chamber. Originally designed to remove fine particulates matter, it was retrofitted to the flue gas control device for simultaneous Hg0 removal. By employing the PAC coating, the Hg removal efficiency of the HF increased to 79.79% from 66.35%. Also, a temporary reduction in Hg removal was seen but this was resolved following a cleaning cycle in which the dust layer was removed. | Jin-Ho Sung Seung-Ki Back Eun-Song Lee Ha-Na Jang Yong-Chil Seo Youn-Suk Kang Myong-Hwa Lee | 2019 | Journal of Environmental Sciences2019,31,6: | 2 |

| 14 | Machine Learning to Detect Alzheimer’s Disease from Circulating Non-coding RNAs显示文摘Blood-borne small non-coding(snc RNAs)are among the prominent candidates for blood-based diagnostic tests.Often,high-throughput approaches are applied to discover biomarker signatures.These have to be validated in larger cohorts and evaluated by adequate statistical learning approaches.Previously,we published high-throughput sequencing based microRNA(miRNA)signatures in Alzheimer’s disease(AD)patients in the United States(US)and Germany.Here,we determined abundance levels of 21 known circulating miRNAs in 465 individuals encompassing AD patients and controls by RT-qPCR.We computed models to assess the relation between miRNA expression and phenotypes,gender,age,or disease severity(Mini-Mental State Examination;MMSE).Of the 21 miRNAs,expression levels of 20 miRNAs were consistently de-regulated in the US and German cohorts.18 miRNAs were significantly correlated with neurodegeneration(Benjamini-Hochberg adjusted P<0.05)with highest significance for miR-532-5 p(BenjaminiHochberg adjusted P=4.8×10^-30).Machine learning models reached an area under the curve(AUC)value of 87.6%in differentiating AD patients from controls.Further,ten miRNAs were significantly correlated with MMSE,in particular miR-26a/26b-5p(adjusted P=0.0002).Interestingly,the miRNAs with lower abundance in AD were enriched in monocytes and T-helper cells,while those up-regulated in AD were enriched in serum,exosomes,cytotoxic t-cells,and B-cells.Our study represents the next important step in translational research for a miRNA-based AD test. | Nicole Ludwig Tobias Fehlmann Fabian Kern Manfred Gogol Walter Maetzler Stephanie Deutscher Simone Gurlit Claudia Schulte Anna-Katharina von Thaler Christian Deuschle Florian Metzger Daniela Berg Ulrike Suenkel Verena Keller Christina Backes Hans-Peter Lenhof Eckart Meese Andreas Keller | 2019 | Genomics, Proteomics & Bioinformatics2019,17,4: | 2 |
