| 2 | Soluble forms of extracellular cytokeratin 18 may differentiate simple steatosis from nonalcoholic steatohepatitis显示文摘AIM: To investigate whether serum levels of two soluble forms of extracellular cytokeratin 18 (M30-antigen and M65-antigen) may differentiate nonalcoholic steatohepatitis (NASH) from simple steatosis in patients with nonalcoholic fatty liver disease (NAFLD). METHODS: A total of 83 patients with suspected NAFLD and 49 healthy volunteers were investigated. Patients with suspected NAFLD were classified according to their liver histology into four groups: definitive NASH (n = 45), borderline NASH (n = 24), simple fatty liver (n = 9), and normal tissue (n = 5). Serum levels of caspase-3 generated cytokeratin-18 fragments (M30-antigen) and total cytokeratin-18 (M65-antigen) were determined by ELISA. RESULTS: Levels of M30-antigen and M65-antigen were significantly higher in patients with definitive NASH compared to the other groups. An abnormal value (> 121.60 IU/L) of M30-antigen yielded a 60.0% sensitivity and a 97.4% specificity for the diagnosis of NASH. Sensitivity and specificity of an abnormal M65-antigen level (> 243.82 IU/L) for the diagnosis of NASH were 68.9% and 81.6%, respectively. Among patients with NAFLD, M30-antigen and M65-antigen levels distinguished between advanced fibrosis and early-stage fibrosis with a sensitivity of 64.7% and 70.6%, and a specificity of 77.3% and 71.2%, respectively. CONCLUSION: Serum levels of M30-antigen and M65-antigen may be of clinical usefulness to identify patients with NASH. Further studies are mandatory to better assess the role of these apoptonecrotic biomarkers in NAFLD pathophysiology. | Yusuf Yilmaz Enver Dolar Engin Ulukaya Semra Akgoz Murat Keskin Murat Kiyici Sibel Aker Arzu Yilmaztepe Selim Gurel Macit Gulten Selim Giray Nak | 2007 | World Journal of Gastroenterology2007，13，6： | 19 |
| 3 | Ultrathin monolithic 3D printed optical coherence tomography endoscopy for preclinical and clinical use显示文摘Preclinical and clinical diagnostics increasingly rely on techniques to visualize internal organs at high resolution via endoscopes.Miniaturized endoscopic probes are necessary for imaging small luminal or delicate organs without causing trauma to tissue.However,current fabrication methods limit the imaging performance of highly miniaturized probes,restricting their widespread application.To overcome this limitation,we developed a novel ultrathin probe fabrication technique that utilizes 3D microprinting to reliably create side-facing freeform micro-optics(<130μm diameter)on single-mode fibers.Using this technique,we built a fully functional ultrathin aberration-corrected optical coherence tomography probe.This is the smallest freeform 3D imaging probe yet reported,with a diameter of 0.457 mm,including the catheter sheath.We demonstrated image quality and mechanical flexibility by imaging atherosclerotic human and mouse arteries.The ability to provide microstructural information with the smallest optical coherence tomography catheter opens a gateway for novel minimally invasive applications in disease. | Jiawen Li Simon Thiele Bryden C.Quirk Rodney W.Kirk Johan W.Verjans Emma Akers Christina A.Bursill Stephen J.Nicholls Alois M.Herkommer Harald Giessen Robert A.McLaughlin | 2020 | Light(Science & Applications)2020，9，1： | 6 |
| 4 | 脑海绵状血管畸形临床诊疗指南概要:血管瘤联盟科学咨询委员会临床专家组基于系统文献评价的共识推荐显示文摘背景尽管脑海绵状血管畸形(cerebral cavernous malformation, CCM)的相关研究文献已相当丰富,但在诊断和治疗策略方面仍存在着争议。目的制订CCM诊疗指南。方法作为代表CCM患者和研究的患者支持团体,血管瘤联盟(www.angioma.org)召集了一个包括CCM临床专家在内的多学科写作组来帮助总结现有的CCM临床诊疗相关文献,重点关注5个主题:(1)流行病学和自然病程;(2)遗传检测和咨询;(3)诊断标准和影像学标准;(4)神经外科注意事项;(5)神经内科注意事项。写作组根据预定方案进行了文献回顾和证据评价,最终制定推荐意见,并且确立了共识、争议和知识空白。结果根据方法学标准从1983年1月1日至2014年9月31日期间公开发表的1 270篇文献中筛选出98篇,并确定了另外38篇近期或相关的文献。各主题作者利用这些文献总结了现有知识并形成了23项共识诊疗推荐,同时根据美国心脏协会/美国卒中协会标准进行了推荐强度(效应量)和证据水平(确定性估计)评级。其中,尚无A级证据(因为缺乏随机对照试验),B级证据11项(48%),C级证据12项(52%);Ⅰ级推荐8项(35%),Ⅱ级推荐10项(43%),Ⅲ级推荐5项(22%)。结论现有证据支持对CCM诊疗的推荐,但这些证据的级别和推荐强度普遍较低,因此需要进一步研究来帮助进行更好的临床实践并更新这些推荐。完整的推荐文档包括引用文献的纳入标准、关于各项推荐更详尽的评判标准以及各种争议和知识空白的总结,同样通过了同行评议并可在线获取(www.angioma.org/CCMGuidelines)。 | Amy Akers Rustam Al-Shahi Salman Issam A.

| 5 | Rapid and flexible segmentation of electron microscopy data using few-shot machine learning显示文摘Automatic segmentation of key microstructural features in atomic-scale electron microscope images is critical to improved understanding of structure–property relationships in many important materials and chemical systems.However,the present paradigm involves time-intensive manual analysis that is inherently biased,error-prone,and unable to accommodate the large volumes of data produced by modern instrumentation.While more automated approaches have been proposed,many are not robust to a high variety of data,and do not generalize well to diverse microstructural features and material systems.Here,we present a flexible,semi-supervised few-shot machine learning approach for segmentation of scanning transmission electron microscopy images of three oxide material systems:(1)epitaxial heterostructures of SrTiO_(3)/Ge,(2)La_(0.8)Sr_(0.2)FeO_(3) thin films,and(3)MoO_(3) nanoparticles.We demonstrate that the few-shot learning method is more robust against noise,more reconfigurable,and requires less data than conventional image analysis methods.This approach can enable rapid image classification and microstructural feature mapping needed for emerging high-throughput characterization and autonomous microscope platforms. | Sarah Akers Elizabeth Kautz Andrea Trevino-Gavito Matthew Olszta Bethany E.Matthews Le Wang Yingge Du Steven R.Spurgeon | 2021 | npj Computational Materials2021，，1： | 3 |

| 7 | Assessing the effect of different natural dissolved organic matters on the cytotoxicity of titanium dioxide nanoparticles with bacteria显示文摘Titanium dioxide nanoparticles(TiO_2 NPs) are among the most widely manufactured nanomaterials on a global scale. However, prudent and vigilant surveillance, incumbent upon the scientific community with the advent of new technologies, has revealed potentially undesirable effects of TiO_2 NPs on biological systems and the natural environment during their application and discharge. Such effects are likely best evaluated by first assessing the fate of the TiO_2 NPs in natural environments. In this study, the effects of terrestrial humic acid(HA) and tannic acid(TA), two major members of the collective:dissolved organic matter(DOM), on the cytotoxicity of TiO_2 NPs to Escherichia coli were investigated in the presence and absence of natural sunlight. Qualitative(transmission electron microscopy(TEM)) and quantitative(LC50) analyses were employed in this study. In addition, the production of reactive oxygen species(ROS) in the form of UOH was further assessed—as HA or TA increased the production of ROS decreased. The inhibition of bacterial viability in the light treatment groups, with respective treatment organics at concentrations of 10 ppm, was less in TA than in terrestrial HA. SAS was used to analyze the treatment effect of individual factors of light irradiation, DOM, and concentration of TiO_2 NPs. | Xiaojia He Donee' McAlliser Winfred G.

| 8 | Microstructural,Mechanical,Electrical,and Thermal Properties of the Bi-Sn-Ag Ternary Eutectic Alloy显示文摘The development of lead-free solders has emerged as one of the key issues in the electronics packaging industries.Bi-Sn-Ag eutectic alloy has been considered as one of the lead-free solder materials that can replace the toxic Pb-Sn eutectic solder without increasing soldering temperature.We investigated the effects of temperature gradient and growth rate on the mechanical,electrical and thermal properties of the BiSn-Ag ternary eutectic alloy.Bi-47 wt%Sn-0.68 wt%Ag alloy was directionally solidified upward with different temperature gradients(G=2.33-5.66 K/mm) at a constant growth rate(V=13.25 μm/s) and with different growth rates(V=6.55-132.83 μm/s) at a constant temperature gradient(G=2.33 K/mm) in the growth apparatus.The microstructures(λ),microhardness(HV),tensile stress(σ),electrical resistivity(ρ),and thermal properties(△H,C_p,T_m) were measured on directionally solidified samples.The dependency of the λ,HV,σ,and ρ on G and V was investigated.According to the experimental results,X values decrease with increasing G and V,but HV,λ,and ρ values increase with increasing G and V.Variations of electrical resistivity(ρ) for cast samples with the temperature in the range of 300-400 K were also measured by using a standard dc four-point probe technique.The enthalpy of fusion(△H) and specific heat(C_p) for the same alloy was also determined by means of differential scanning calorimeter(DSC) from heating trace during the transformation from eutectic liquid to eutectic solid. | KAYA Hasan ENGÍN Sevda AKER Aynur BüYüK Ugur ÇADIRLI Emin | 2017 | Journal of Wuhan University of Technology(Materials Science)2017，32，1： | 2 |
| 9 | Anti-inflammatory efficiency of levobupivacaine in an experimental colitis model显示文摘AIM:To investigate the efficiency of levobupivacaine in treating experimentally induced colitis in rats.METHODS:Colitis was induced by trinitrobenzene sulfonic acid and ethanol in 30 rats under general anesthesia,and 10 rats were used as a sham group.Subsequent to induction of colitis,rats were divided into three groups;budesonide group received 0.1 mg/kg budesonide,levobupivacaine group received 10 mg/kg levobupivacaine and saline group received 1 mL saline solution via rectal route for 7 d.In the sham group,only routine rectal catheterization was performed without use of any material.At the end of 7 d,laparotomy and total colectomy were performed for histopathological ex-amination in all rats and blood samples were drawn for measurement of tumor necrosis factor(TNF)-αand interleukin(IL)-6 following cardiac puncture.Macroscopic and microscopic evaluations of the specimens were performed by a pathologist blinded to group assignment of the rats.RESULTS:Weight loss(P=0.016)and macroscopic examination scores(P=0.001)were significantly higher in saline group than others.Histopathological scoring was comparable between all colitis groups(P=0.350).There was no significant difference in TNF-αlevels and IL-6 levels(P=0.150).CONCLUSION:The significant improvement in macroscopic scores suggests that levobupivacaine may have topical anti-inflammatory effects in an experimental colitis model;however,this finding was not supported by microscopic findings. | Ugur Duman Aysun Yilmazlar Ersin Ozturk Sibel Aker Emre Sarandol Tuncay Yilmazlar | 2010 | World Journal of Gastroenterology2010，16，20： | 2 |
