1Ultra-thin, planar, Babinet-inverted plasmonic metalenses显示文摘We experimentally demonstrate the focusing of visible light with ultra-thin,planar metasurfaces made of concentrically perforated,30-nm-thick gold films.The perforated nano-voids—Babinet-inverted(complementary)nano-antennas—create discrete phase shifts and form a desired wavefront of cross-polarized,scattered light.The signal-to-noise ratio in our complementary nano-antenna design is at least one order of magnitude higher than in previous metallic nano-antenna designs.We first study our proof-of-concept‘metalens’with extremely strong focusing ability:focusing at a distance of only 2.5 mm is achieved experimentally with a 4-mm-diameter lens for light at a wavelength of 676 nm.We then extend our work with one of these‘metalenses’and achieve a wavelength-controllable focal length.Optical characterization of the lens confirms that switching the incident wavelength from 676 to 476 nm changes the focal length from 7 to 10 mm,which opens up new opportunities for tuning and spatially separating light at different wavelengths within small,micrometer-scale areas.All the proposed designs can be embedded on-chip or at the end of an optical fiber.The designs also all work for two orthogonal,linear polarizations of incident light.Xingjie Ni Satoshi Ishii Alexander V Kildishev Vladimir M Shalaev 2013Light(Science & Applications)2013,2,1:20
2Mitochondrial dysfunction and mitochondrial DNA mutations in atherosclerotic complications in diabetes显示文摘Mitochondrial DNA(mtDNA) is particularly prone to oxidation due to the lack of histones and a deficient mismatch repair system.This explains an increased mutation rate of mtDNA that results in heteroplasmy,e.g.,the coexistence of the mutant and wild-type mtDNA molecules within the same mitochondrion.In diabetes mellitus,glycotoxicity,advanced oxidative stress,collagen cross-linking,and accumulation of lipid peroxides in foam macrophage cells and arterial wall cells may significantly decrease the mutation threshold required for mitochondrial dysfunction,which in turn further contributes to the oxidative damage of the diabetic vascular wall,endothelial dysfunc-tion,and atherosclerosis.Dimitry A Chistiakov Igor A Sobenin Yuri V Bobryshev Alexander N Orekhov 2012World Journal of Cardiology2012,4,5:17
3Role of the endothelium in inflammatory bowel diseases显示文摘Inflammatory bowel diseases(IBD) are a complex group of diseases involving alterations in mucosal immunity and gastrointestinal physiology during both initiation and progressive phases of the disease.At the core of these alterations are endothelial cells,whose continual adjustments in structure and function coordinate vascular supply,immune cell emigration,and regulation of the tissue environment.Expansion of the endothelium in IBD(angiogenesis),mediated by inflammatory growth factors,cytokines and chemokines,is a hallmark of active gut disease and is closely related to disease severity.The endothelium in newly formed or inflamed vessels differs from that in normal vessels in the production of and response to inflammatory cytokines,growth factors,and adhesion molecules,altering coagulant capacity,barrier function and blood cell recruitment in injury.This review examines the roles of the endothelium in the initiation and propagation of IBD pathology and distinctive features of the intestinal endothelium contributing to these conditions.Walter E Cromer J Michael Mathis Daniel N Granger Ganta V Chaitanya J Steven Alexander 2011World Journal of Gastroenterology2011,17,5:10
4Near-infrared fluorescence sentinel lymph node detection in gastric cancer: A pilot study显示文摘AIM: To investigate feasibility and accuracy of nearinfrared fluorescence imaging using indocyanine green: nanocolloid for sentinel lymph node(SLN) detection in gastric cancer.METHODS: A prospective, single-institution, phaseI feasibility trial was conducted. Patients suffering from gastric cancer and planned for gastrectomy were included. During surgery, a subserosal injection of 1.6 m L ICG:Nanocoll was administered around the tumor. NIR fluorescence imaging of the abdominal cavity was performed using the Mini-FLARE? NIR fluorescence imaging system. Lymphatic pathways and SLNs were visualized. Of every detected SLN, the corresponding lymph node station, signal-to-background ratio and histopathological diagnosis was determined. Patients underwent standard-of-care gastrectomy. Detected SLNs outside the standard dissection planes were also resected and evaluated.RESULTS: Twenty-six patients were enrolled. Four patients were excluded because distant metastases were found during surgery or due to technical failure of the injection. In 21 of the remaining 22 patients, at least 1 SLN was detected by NIR Fluorescence imaging(mean 3.1 SLNs; range 1-6). In 8 of the 21 patients, tumor-positive LNs were found. Overall accuracy of the technique was 90%(70%-99%; 95%CI), which decreased by higher p T-stage(100%, 100%, 100%, 90%, 0% for respectively Tx, T1, T2, T3, T4 tumors). All NIR-negative SLNs were completely effaced by tumor. Mean fluorescence signal-to-background ratio of SLNs was 4.4(range 1.4-19.8). In 8 of the 21 patients, SLNs outside the standard resection plane were identified, that contained malignant cells in 2 patients.CONCLUSION: This study shows successful use of ICG:Nanocoll as lymphatic tracer for SLN detection in gastric cancer. Moreover, tumor-containing LNs outside the standard dissection planes were identified.Quirijn RJG Tummers Leonora SF Boogerd Wobbe O de Steur Floris PR Verbeek Martin C Boonstra Henricus JM Handgraaf John V Frangioni Cornelis JH van de Velde Henk H Hartgrink Alexander L Vahrmeijer 2016World Journal of Gastroenterology2016,22,13:9
5Efficacy and safety of tenofovir in chronic hepatitis B: Australian real world experience显示文摘AIM To evaluate the long-term treatment outcomes of tenofovir therapy in patients in a real world Australian tertiary care setting.METHODS We performed a retrospective analysis of treatment outcomes among treatment-na?ve and treatment-experienced patients receiving a minimum 3 mo tenofovir therapy through St Vincent's Hospital Melbourne, Australia. We included patients receiving tenofovir [tenofovir disoproxil fumarate(TDF)] monotherapy, as well as patients treated with TDF in combination with a second antiviral agent. Patients were excluded if they demonstrated human immune-deficiency virus/hepatitis C virus/hepatitis delta virus coinfection or were less than 18 years of age. We considered virological and biochemicalresponse, as well as safety outcomes. Virological response was determined by measurement of hepatitis B virus(HBV) DNA using sensitive assays; biochemical response was determined via serum liver function tests; histological response was determined from liver biopsy and fibroscan; safety analysis focused on glomerular renal function and bone mineral density. The primary efficacy endpoint was complete virological suppression over time, defined by HBV DNA < 20 IU/m L. Secondary efficacy endpoints included rates of biochemical response, and HB e antigen(HBe Ag)/HB surface antigen loss and seroconversion over time.RESULTS Ninety-two patients were identified who fulfilled the enrolment criteria. Median follow-up was 26 mo(range 3-114). Mean age was 46(24-78) years, 64(70%) were male and 77(84%) were of Asian origin. 55(60%) patients were treatment-na?ve and 62 patients(67%) were HBe Ag-negative. Complete virological suppression was achieved by 45/65(71%) patients at 12 mo, 37/46(80%) at 24 mo and 25/28(89%) at 36 mo. Partial virological response(HBV DNA 20-2000 IU/m L) was achieved by 89/92(96.7%) of patients. Multivariate analysis showed a significant relationship between virological suppression at end of follow-up and baseline HBV DNA level(OR = 0.897, 95%CI: 0.833-0.967, P = 0.0046) and HBe Ag positive status(OR = 0.373, 95%CI: 0.183-0.762, P = 0.0069). There was no difference in response comparing treatment-na?ve and treatment-experienced patients. Three episodes of virological breakthrough occurred in the setting of noncompliance. Tenofovir therapy was well tolerated.CONCLUSION Tenofovir is an efficacious, safe and well-tolerated treatment in an Australian real-world tertiary care setting. Our data are similar to the reported experience from registration trials.Grace C Lovett Tin Nguyen David M Iser Jacinta A Holmes Robert Chen Barbara Demediuk Gideon Shaw Sally J Bell Paul V Desmond Alexander J Thompson 2017World Journal of Hepatology2017,9,1:7
6Near-infrared fluorescence imaging of a solitary fibrous tumor of the pancreas using methylene blue显示文摘A 67-year-old female presented with unexplained abdominal pain. A contrast-enhanced computed tomography scan of the abdomen incidentally revealed a mass in the uncinate process of the pancreas. This mass was resected and based on histopathological findings, diagnosed as a solitary fibrous tumor (SFT) of the pancreas. A SFT is an extremely rare benign mesenchymal tumor that in 65% of cases affects the visceral pleura but can also affect extra-pleural sites. The intraoperative demarcation of pancreatic tumors, such as SFTs, can bechallenging. In this report, the first clear intraoperative identification of a SFT of the pancreas in a human was shown using near-infrared fluorescence and methylene blue.Joost R van der Vorst Alexander L Vahrmeijer Merlijn Hutteman Tjalling Bosse Vincent THBM Smit Cornelis JH van de Velde John V Frangioni Bert A Bonsing 2012World Journal of Gastrointestinal Surgery2012,4,7:7
7Methods for the extraction and RNA profiling of exosomes显示文摘AIM:To develop protocols for isolation of exosomes and characterization of their RNA content.METHODS:Exosomes were extracted from He La cell culture media and human blood serum using the Total exosome isolation(from cell culture media)reagent,and Total exosome isolation(from serum)reagent respectively.Identity and purity of the exosomes was confirmed by Nanosight?analysis,electron microscopy,and Western blots for CD63 marker.Exosomal RNA cargo was recovered with the Total exosome RNA and protein isolation kit.Finally,RNA was profiled using Bioanalyzer and quantitative reverse transcriptionpolymerase chain reaction(q RT-PCR)methodology.RESULTS:Here we describe a novel approach for robust and scalable isolation of exosomes from cell culture media and serum,with subsequent isolation and analysis of RNA residing within these vesicles.The isolation procedure is completed in a fraction of the time,compared to the current standard protocols utilizing ultracentrifugation,and allows to recover fully intact exosomes in higher yields.Exosomes were found tocontain a very diverse RNA cargo,primarily short sequences 20-200 nt(such as mi RNA and fragments of m RNA),however longer RNA species were detected as well,including full-length 18S and 28S r RNA.CONCLUSION:We have successfully developed a set of reagents and a workflow allowing fast and efficient extraction of exosomes,followed by isolation of RNA and its analysis by q RT-PCR and other techniques.Emily Zeringer Mu Li Tim Barta Jeoffrey Schageman Ketil Winther Pedersen Axl Neurauter Susan Magdaleno Robert Setterquist Alexander V Vlassov 2013World Journal of Methodology2013,3,1:5
8Cancer and age related colonic crypt deficiencies in cytochrome c oxidase Ⅰ显示文摘AIM: To investigate whether defi ciency of expressionof cytochrome c oxidase I (CcOI) in colonic crypts is associated with colon cancer.METHODS: The pattern and level of expression of CcOI in non-neoplastic colonic crypts,and in dysplastic tissues,was assessed using standard immunohis-tochemical methods.Biopsies were obtained from individuals undergoing colonoscopies for screening purposes or for a medically indicated reason.Tissue samples were also obtained from surgical colonic resections.Samples from resections were taken from colonic mucosa 1 and 10 cm from tumors and from the tumors themselves.Samples were evaluated for frequency of crypts with reduced or absent expression of CcOI.In most crypts the loss was apparent throughout the entire crypt,while in a small minority the loss was segmental.The strong immunoreactivity using this monoclonal antibody makes the scoring unambiguous.The percent of crypts with reduced or absent expression of CcOI or (infrequent) segmented loss of expression was then calculated.Data analyses were performed using SPSS statistical package 17.0.RESULTS: The average frequency of CcOI deficient crypts (CcOI-DC) is low in individuals between 20 and 39 years of age,with 0.48% ± 0.40% CcOI-DC for women and 1.80% ± 0.35% for men.CcOI-DC increases after age 40 years,so that between the ages of 40 and 44 years the average frequency of CcOI- DC goes up to 5.89% ± 0.84% in women and 2.15% ± 1.27% in men.By 80-84 years of age,the average frequency of CcOI-DC goes up in women to 15.77% ± 0.97% and in men to 22.6% ± 0.65%.The increases in CcOI-DC from ages 40-44 years compared to 80-84 years in women and men are significantly different with P < 0.01.For women over age 60 years,deficiency of CcOI expression is greater in those women who have had a cancer in their colon.The frequency of CcOI-DC,measured in men,increased in tissues adjacent to colon cancer,being 4.03% ± 0.27% in individuals free of neoplasia in the age range 55-64 yearsand 14.13% ± 0.35% in resected histologically normal tissue of men with cancer in the same age range,P < 0.001.Similar signifi cant differences were noted in older age ranges.The frequency of CcOI-DC crypts in the cecum and sigmoid colon of an individual are signifi cantly correlated,with an R2 = 0.414 for women and R2 = 0.528 for men,P < 0.001.This suggests that the factors determining the level of CcOI deficiency act throughout the colon.Most defective crypts are in clusters of two or more,a likely consequence of crypt fission.In the non-neoplastic margins of cancers,crypts are frequently defi cient for CcOI,and such crypts may appear in large clusters,some containing more than 100 defi cient crypts.CcOI defi ciency is also apparent in colon cancers and sometimes involves a large section of the tumor.Overall,CcOI deficient cells can be visualized in segments of crypts,in whole crypts that increase in frequency with age,in crypts undergoing f ission,in clusters of crypts where the clusters increase in size with age,in increased frequency near tumors,in large clusters in the intimate margins of tumors,and in the tumors themselves.There is no clear dividing line between early stages that can be considered aspects of aging and later stages that can be considered aspects of the progression to cancer.This ambiguity may re ect a rather general situation leading to adult cancer where the early stages of cellular change appear to be relatively innocuous features of the aging process but over decades may evolve into malignancy.CONCLUSION: CcOI defi cient crypts increase in frequency with age,and clusters of defi cient crypts are associated with,and may give rise to,colon cancer.Carol Bernstein Alexander Facista Huy Nguyen Beryl Zaitlin Nadia Hassounah Cristy Loustaunau Claire Margaret Payne Bhaskar Banerjee Steve Goldschmid V Liana Tsikitis Robert Krouse Harris Bernstein 2010World Journal of Gastrointestinal Oncology2010,2,12:5
9Enhanced expression of interleukin-18 in serum and pancreas of patients with chronic pancreatitis显示文摘AIM: To investigate interleukin-18 (IL-18) in patients with chronic panreatitis (CP). METHODS: We studied 29 patients with CP and 30 healthy controls. Peripheral blood mononuclear cells (PBMC) were isolated and incubated with 50 mmol/L ethanol, lipopolysaccharide (LPS) (doses 25 g/L, 250 g/L, 2500 g/L) and both agents for 24 h. Levels of IL-18 in the supernatants, and levels of IL-18, IL-12, interferon (IFN)-γ and soluble CD14 in the serum were analysed by ELISA technique. Expression of IL-18 in PBMC was investigated by reverse-transcription (RT)-PCR. IL-18 protein levels in CP tissue and in normal pancreas were studied by ELISA technique. IL-18 levels in PBMC and pancreatic tissue were determined by Westernblot. Im-munohistochemistry for pancreatic IL-18 expression was performed. RESULTS: In patients, IL-18 serum levels were signifi-cantly enhanced by 76% (mean: 289.9 ± 167.7 ng/L) compared with controls (mean: 165.2 ± 43.6 ng/L; P < 0.0005). IL-12 levels were enhanced by 25% in patients (18.3 ± 7.3 ng/L) compared with controls (14.7 ± 6.8ng/L, P = 0.0576) although not reaching the statistical significance. IFN-γ and soluble CD14 levels were not in-creased. In vitro, LPS stimulated significantly and dose-dependently IL-18 secretion from PBMC. Incubation with ethanol reduced LPS-stimulated IL-18 secretion by about 50%. The mRNA expression of IL-18 in PBMC and the response of PBMC to ethanol and LPS was similar in CP patients and controls. In PBMC, no significant differences in IL-18 protein levels were detected between patients and controls. IL-18 protein levels were increased in CP tissues compared to normal pancreatic tissues. IL-18 was expressed by pancreatic acinar cells and by infiltrating inflammatory cells within the pancreas. CONCLUSION: IL-18 originates from the chronically inflammed pancreas and appears to be involved in the fibrotic destruction of the organ.Alexander Schneider Stephan L Haas Ralf Hildenbrand Sren Siegmund Iris Reinhard Helmut Nakovics Manfred V Singer Peter Feick 2006World Journal of Gastroenterology2006,12,40:4

11Long-term survival of a patient after resection of a gastrointestinal stromal tumor arising from the pancreas显示文摘BACKGROUND:Gastrointestinal stromal tumors (GISTs) may arise in any part of the gastrointestinal tract;extragastrointestinal locations are extremely rare.Only a few cases of extragastrointestinal stromal tumor arising from the pancreas were reported.None of the reports described a long-term follow-up of the patients.METHOD:This report describes an interesting and unusual case of GIST arising from the pancreas.RESULTS:A 74-year-old female presented with a palpable abdominal mass.CT scan showed a large mass 11×8×4 cm originating from the tail of the pancreas.Percutaneous biopsy revealed a GIST predominantly with spindle cells,but some parts also contained epitheloid cells.The patient was treated by distal pancreatic resection with splenectomy.Immunohistochemistry of the tumor showed a staining pattern characteristic of GIST.The patient has achieved a long-term survival of five years and six months without any sign of recurrence of the disease.CONCLUSION:This is the first reported case of an extragastrointestinal stromal tumor arising from the pancreas treated surgically,with a long-term survival.Filip eka Bohumil Jon Alexander Ferko Zdeněk ubrt Dimitar H Nikolov Věra Tyová 2011Hepatobiliary & Pancreatic Diseases International2011,10,3:3
12Association of the level of heteroplasmy of the 15059G>A mutation in the MT-CYB mitochondrial gene with essential hypertension显示文摘AIM: To examine whether the heteroplasmy level for 15059G>A mutation in the mitochondrial genome might be associated with essential hypertension. METHODS: This cross-sectional study involved 196 unrelated participants randomly selected from general population (90 males and 106 females) who underwent a regular medical check-up at the Institute for Ath-erosclerosis Research (Moscow, Russia). One hundred and twenty of them (61%) had essential hypertension, and 76 (39%) were apparently healthy normotensive persons. The level of heteroplasmy for 15059G>A mutation occurring in the coding region of cytochrome b gene (MT-CYB) of mtDNA isolated from the blood leukocytes, was quantified using DNA pyrosequencing method. RESULTS: The 15059G>A heteroplasmy level ranged between 4% and 83%, with a median level of 31%. Between the upper and lower quartiles of 15059G>A heteroplasmy distribution, significant differences were observed for patients' age, systolic blood pressure, and triglyceride levels. 15059G>A heteroplasmy correlated both with age (r = 0.331, P < 0.001) and the presence of hypertension (r = 0.228, P = 0.002). Regression analysis revealed that the age explains 12% variability of 15059G>A heteroplasmy, and hypertension independently explains more 5% variability. The 15059G>A heteroplasmy exceeding 31% was found to be significantly associated with a higher risk of essential hypertension (odds ratio 2.76; P (Fisher) 0.019]. The study participants with high 15059G>A heteroplasmy level were found to have significantly higher age (P < 0.001) and the prevalence of essential hypertension (P = 0.033), as compared to those with low 15059G>A heteroplasmy level. These observations suggested a positive correlation between the level of 15059G>A heteroplasmy and essential hypertension. CONCLUSION: This study provides the evidence of association of mtDNA 15059G>A mutation heteroplasmy with essential hypertension.Igor A Sobenin Dimitry A Chistiakov Margarita A Sazonova Maria M Ivanova Yuri V Bobryshev Alexander N Orekhov Anton Y Postnov 2013World Journal of Cardiology2013,5,5:3
13Hepatocellular carcinoma with child Pugh-A Cirrhosis treated with stereotactic body radiotherapy显示文摘AIM To evaluate the control, survival, and hepatic function for Child Pugh(CP)-A patients after Stereotactic body radiotherapy(SBRT) in hepatocellular carcinoma(HCC).METHODS From 2009 to 2016, 40 patients with Barcelona Liver Clinic(BCLC) stages 0-B HCC and CP-A cirrhosis completed liver SBRT. The mean prescription dose was 45 Gy(40 to 50 Gy in 4-5 fractions). Local relapse, defined as recurrence within the planning target volume was assessed with intravenous multiphase contrast computed tomography or magnetic resonance imaging every 4-6 mo after completion of SBRT. Progression of cirrhosis was evaluated by CP and Model for End Stage Liver Disease scores every 3-4 mo. Toxicities were graded per the Common Terminology Criteria for Adverse Events(v4.03). Median follow-up was 24 mo.RESULTS Forty-nine HCC lesions among 40 patients were analyzed in this IRB approved retrospective study. Median tumor diameter was 3.5 cm(1.5-8.9 cm). Six patients with tumors ≥ 5 cm completed planned selected transarterial chemoembolization(TACE) in combination with SBRT. Eight patients underwent orthotropic live transplant(OLT) with SBRT as a bridging treatment(median time to transplant was 12 mo, range 5 to 23 mo). The Pathologic complete response(PCR) rate in this group was 62.5%. The 2-year in-field local control was 98%(1 failure). Intrahepatic control was 82% and 62% at 1 and 2 years, respectively. Overall survival(OS) was 92% and 60% at 1 and 2 years, with a median survival of 41 mo per Kaplan Meier analysis. At 1 and 2 years, 71% and 61% of patients retained CPA status. Of the patients with intrahepatic failures, 58% developed progressive cirrhosis, compared to 27% with controlled disease(P = 0.06). Survival specific to hepatic failure was 92%, 81%, and 69% at 12, 18, and 24 mo. There was no grade 3 or higher toxicity. On univariate analysis, gross tumor volume(GTV) < 23 cc was associated with freedom from CP progression(P = 0.05), hepatic failure-specific survival(P = 0.02), and trended with OS(P = 0.10).CONCLUSION SBRT is safe and effective in HCC with early cirrhosis and may extend waiting time for transplant in patients who may not otherwise be immediate candidates.Shaakir Hasan Ngoc Thai Tadahiro Uemura Vijay Kudithipudi Paul Renz Stephen Abel Alexander V Kirichenko 2017World Journal of Gastrointestinal Surgery2017,9,12:2
14Metal-organic frameworks based surface-enhanced Raman spectroscopy technique for ultra-sensitive biomedical trace detection显示文摘Metal-organic frameworks(MOFs)have attracted widespread interest due to their unique and unprecedented advantages in microstructures and properties.Besides,surface-enhanced Raman scattering(SERS)technology has also rapidly developed into a powerful fingerprint spectroscopic technique that can provide rapid,non-invasive,non-destructive,and ultra-sensitive detection,even down to single molecular level.Consequently,a considerable amount of researchers combined MOFs with the SERS technique to further improve the sensing performance and broaden the applications of SERS substrates.Herein,representative synthesis strategies of MOFs to fabricate SERS-active substrates are summarized and their applications in ultra-sensitive biomedical trace detection are also reviewed.Besides,relative barriers,advantages,disadvantages,future trends,and prospects are particularly discussed to give guidance to relevant researchers.Yuna Zhang Cuili Xue Yuli Xu Shengsheng Cui Alexander A.Ganeev Kistenev Yury V Anna Gubal Victoria Chuchina Han Jin Daxiang Cui 2023Nano Research2023,16,2:2

20Intimal pericytes as the second line of immune defence in atherosclerosis显示文摘Inflammation plays an essential role in the development of atherosclerosis. The initiation and growth of atherosclerotic plaques is accompanied by recruitment of inflammatory and precursor cells from the bloodstream and their differentiation towards pro-inflammatory phenotypes. This process is orchestrated by the production of a number of pro-inflammatory cytokines and chemokines. Human arterial intima consists of structurally distinct leaflets, with a proteoglycan-rich layer lying immediately below the endothelial lining. Recent studies reveal the important role of stellate pericyte-like cells(intimal pericytes) populating the proteoglycan-rich layer in the development of atherosclerosis. During the pathologic process, intimal pericytes may participate in the recruitment of inflammatory cells by producing signalling molecules and play a role in the antigen presentation. Intimal pericytes are also involved in lipid accumulation and the formation of foam cells. This review focuses on the role of pericytelike cells in the development of atherosclerotic lesions.Ekaterina A Ivanova Yuri V Bobryshev Alexander N Orekhov 2015World Journal of Cardiology2015,7,10:2
