| 1 | Different antibiotic susceptibility between antrum and corpus of the stomach,a possible reason for treatment failure of Helicobacter pylori infection显示文摘AIM:To assess whether antibiotic resistance varies between the antrum and corpus of the stomach of patients that are either Helicobacter pylori(H.pylori)therapy-naive or pre-treated.METHODS:H.pylori strains were isolated from antrum and corpus biopsies from 66 patients that received a diagnostic gastroduodenoscopy for variant clinical indications.Antimicrobial susceptibility to amoxicillin,clarithromycin,tetracycline,metronidazole,levofloxacin and rifabutin was tested with the E-test method on IsoSensitest agar with 10 vol%defibrinated horse blood.In patients with a different antibiotic susceptibility pattern between the isolates from the antrum and corpus,DNA fingerprinting via random amplified polymorphic DNA analysis was performed to detect differences among DNA patterns of H.pylori isolates.RESULTS:Primary,secondary and tertiary resistance to clarithromycin was 6.9%,53.8%and 83.3%,retrospectively.Metronidazole and levofloxacin resistance also increased according to the number of previous treatments(17.2%,69.2%,83.3%;13.8%,23.1%,33.3%).Tertiary resistance to rifabutin was detected in12.5%of patients.In none of the 66 patients a resistance against amoxicillin or tetracycline was detectable.Discordant antibiotic susceptibility between antrum and corpus isolates for different antibiotics was seen in 15.2%(10/66)of the patients.Two out of those ten patients were naive to any H.pylori antibiotic treatment.The remaining eight patients previously received at least one eradication therapy.DNA fingerprinting analysis revealed no substantial differences among DNA patterns between antrum and corpus isolates in the majority of patients suggesting an infection with a single H.pylori strain.CONCLUSION:Different antibiotic susceptibility between antrum and corpus biopsies is a common phenomenon and a possible explanation for treatment failure.Resistant H.pylori strains may be missed if just one biopsy from one anatomic site of the stomach is taken for H.pylori susceptibility testing. | Michael Selgrad Ina Tammer Cosima Langner Jan Bornschein Julia Mei?le Arne Kandulski Mariya Varbanova Thomas Wex Dirk Schlüter Peter Malfertheiner | 2014 | World Journal of Gastroenterology2014,20,43: | 10 |
| 2 | Fiber-enriched diet helps to control symptoms and improves esophageal motility in patients with non-erosive gastroesophageal reflux disease显示文摘AIM To investigate the effect of dietary fiber on symptoms and esophageal function testing parameters in nonerosive gastroesophageal reflux disease(GERD)(NERD) patients.METHODS Thirty-six NERD patients with low(< 20 g/d) dietary fiber intake were enrolled in the study. They were examined with the use of symptom questionnaire(GERD-Q), highresolution esophageal manometry, 24-h esophageal p Himpedance examinations, and food frequency questionnaire before and after 10 d of usual diet supplemented by psyllium 5.0 g TID. Complete data of 30 patients were available to the final analysis. The obtained results were analyzed with the use of non-parametric statistics(Wilcoxon matched pairs test). RESULTS The number of patients experiencing heartburn was less(93.3% at baseline vs 40% at the end of the study, P < 0.001) and the GERD-Q score decreased(mean ± SD: 10.9 ± 1.7 vs 6.0 ± 2.3, P < 0.001) after the treatment period. Minimal resting lower esophageal sphincter(LES) pressure increased from 5.41 ± 10.1 to 11.3 ± 9.4 mm Hg(P = 0.023), but no change in residual LES pressure and mean resting pressure was found. Total number of gastroesophageal refluxes(GER) decreased from 67.9 ± 17.7 to 42.4 ± 13.5(P < 0.001) predominantly by acid and weak acid types of GERs. No significant change in mean esophageal p H and % of time p H < 4 was registered. Maximal reflux time decreased from 10.6 ± 12.0 min to 5.3 ± 3.7 min(P < 0.05). CONCLUSION Fiber-enriched diet led to a significant increase of minimal lower esophageal sphincter resting pressure, a decrease of number of gastroesophageal refluxes, and a decrease of heartburn frequency per week in NERD. | Sergey Morozov Vasily Isakov Mariya Konovalova | 2018 | World Journal of Gastroenterology2018,24,21: | 9 |
| 3 | Modification of titanium surface via Ag-,Sr-and Si-containing micro-arc calcium phosphate coating显示文摘The current research is devoted to the study of the modification of the titanium implants by the micro-arc oxidation with bioactive calcium phosphate coatings containing Ag or Sr and Si elements.The coatings’microstructure,phase composition,morphology,physicochemical and biological properties were examined by scanning electron microscopy(SEM),transmission electron microscopy(TEM),energy-dispersive X-ray spectroscopy(EDX)and X-ray diffraction(XRD).Ag-containing and Sr-Si-incorporated coatings were formed in alkaline and acid electrolytes,respectively.The formation of the coatings occurred at different ranges of the applied voltages,which led to the significant difference in the coatings properties.The trace elements Ag,Sr and Si participated intensively in the plasma-chemical reactions of the micro-arc coatings formation.Ag-containing coatings demonstrated strong antibacterial effect against Staphylococcus aureus AТСС6538-P.MTT in vitro test with 3T3-L1 fibroblasts showed no cytotoxicity appearance on Sr-Si-incorporated coatings. | Mariya B.Sedelnikova Ekaterina G.Komarova Yurii P.Sharkeev Anna V.Ugodchikova Tatiana V.Tolkacheva Julietta V.Rau Evgeny E.Buyko Vladimir V.Ivanov Vladimir V.Sheikin | 2019 | Bioactive Materials2019,4,1: | 6 |

| 6 | A simple scoring system to estimate perioperative mortality following liver resection for primary liver malignancy-the Hepatectomy Risk Score(HeRS)显示文摘Background:Selection of the optimal treatment modality for primary liver cancers remains complex,balancing patient condition,liver function,and extent of disease.In individuals with preserved liver function,liver resection remains the primary approach for treatment with curative intent but may be associated with significant mortality.The purpose of this study was to establish a simple scoring system based on Model for End-stage Liver Disease(MELD)and extent of resection to guide risk assessment for liver resections.Methods:The 2005-2015 NSQIP database was queried for patients undergoing liver resection for primary liver malignancy.We first developed a model that incorporated the extent of resection(1 point for major hepatectomy)and a MELD-Na score category of low(MELD-Na=6,1 point),medium(MELD-Na=7-10,2 points)or high(MELD-Na>10,3 points)with a score range of 1-4,called the Hepatic Resection Risk Score(HeRS).We tested the predictive value of this model on the dataset using logistic regression.We next developed an optimal multivariable model using backwards sequential selection of variables under logistic regression.We performed K-fold cross validation on both models.Receiver operating characteristics were plotted and the optimal sensitivity and specificity for each model were calculated to obtain positive and negative predictive values.Results:A total of 4,510 patients were included.HeRS was associated with increased odds of 30-day mortality[HeRS=2:OR=3.23(1.16-8.99),P=0.025;HeRS=3:OR=6.54(2.39-17.90),P<0.001;HeRS=4:OR=13.69(4.90-38.22),P<0.001].The AUC for this model was 0.66.The AUC for the optimal multivariable model was higher at 0.76.Under K-fold cross validation,the positive predictive value(PPV)and negative predictive value(NPV)of these two models were similar at PPV=6.4%and NPV=97.7%for the HeRS only model and PPV=8.4%and NPV=98.1%for the optimal multivariable model.Conclusions:The HeRS offers a simple heuristic for estimating 30-day mortality after resection of primary liver malignancy.More complicated models offer better performance but at the expense of being more difficult to integrate into clinical practice. | Dimitrios Moris Brian I.Shaw Cecilia Ong Ashton Connor Mariya L.Samoylova Samuel J.Kesseli Nader Abraham Jared Gloria Robin Schmitz Zachary W.Fitch Bryan M.Clary Andrew S.Barbas | 2021 | Hepatobiliary Surgery and Nutrition2021,10,3: | 2 |
| 7 | 俄罗斯及青藏高原野生雁类在禽流感病毒传播中的作用(英文)显示文摘雁形目和鸻形目鸟类是低致病性禽流感病毒(正粘病毒科)的自然宿主。水禽中野生雁类(雁形目)的迁徙距离达数千公里。从野生雁类中分离出禽流感病毒的成功率很低。本研究旨在检测俄罗斯境内以及青藏高原营巢繁殖的不同野生雁类的禽流感病毒,分析所得数据后进一步明确这些鸟类在病原体传播中的作用。我们检测了来自俄罗斯境内9个地区以及青藏高原(西藏自治区)的3245份样品,未发现禽流感病毒。这表明,野生雁类在长距离迁徙过程中对禽流感的传播并没未起到明显作用。因此,野生雁类可能不是主要的禽流感病毒的自然宿主,但野生雁类种群中禽流感病毒的状况仍需进一步探究。对野生雁类与禽流感病毒的生态学研究有助于我们掌握更多的病原与宿主间关系的信息,以便更好地维持野生雁类种群数量。 | Mariya V.SIVAY Nikita Y.SILKO Kirill A.SHARSHOV Aleksander V.PROKUDIN 李来兴 杨敏 操胜 Aleksander M.SHESTOPALOV | 2011 | Chinese Birds2011,,3: | 2 |
| 8 | Embedding physics domain knowledge into a Bayesian network enables layer-by-layer process innovation for photovoltaics显示文摘Process optimization of photovoltaic devices is a time-intensive,trial-and-error endeavor,which lacks full transparency of the underlying physics and relies on user-imposed constraints that may or may not lead to a global optimum.Herein,we demonstrate that embedding physics domain knowledge into a Bayesian network enables an optimization approach for gallium arsenide(GaAs)solar cells that identifies the root cause(s)of underperformance with layer-by-layer resolution and reveals alternative optimal process windows beyond traditional black-box optimization.Our Bayesian network approach links a key GaAs process variable(growth temperature)to material descriptors(bulk and interface properties,e.g.,bulk lifetime,doping,and surface recombination)and device performance parameters(e.g.,cell efficiency).For this purpose,we combine a Bayesian inference framework with a neural network surrogate device-physics model that is 100×faster than numerical solvers.With the trained surrogate model and only a small number of experimental samples,our approach reduces significantly the time-consuming intervention and characterization required by the experimentalist.As a demonstration of our method,in only five metal organic chemical vapor depositions,we identify a superior growth temperature profile for the window,bulk,and back surface field layer of a GaAs solar cell,without any secondary measurements,and demonstrate a 6.5%relative AM1.5G efficiency improvement above traditional grid search methods. | Zekun Ren Felipe Oviedo Maung Thway Siyu I.P.Tian Yue Wang Hansong Xue Jose Dario Perea Mariya Layurova Thomas Heumueller Erik Birgersson Armin G.Aberle Christoph J.Brabec Rolf Stangl Qianxiao Li Shijing Sun Fen Lin Ian Marius Peters Tonio Buonassisi | 2020 | npj Computational Materials2020,,1: | 2 |
