1从AO传统加压接骨板到新型内固定器原则显示文摘骨折内固定中生物学的重要性和保护骨和软组织,作为AO的第4项原则已受重视。AO传统加压接骨板对骨面的压迫会干扰骨皮质的血运,引起接骨板下方骨的结构性改变。有限接触动力加压接骨板(LC-DCP)可减小接骨板和骨的接触面积。锁定螺丝钉(LHS)、点接触固定器(PCFix)及微创固定系统(LISS)设计则因接骨板与骨面无接触和压迫,是新的一次变革。这种内固定器原理的概念可以用外固定支架来理解,可以防止任何对骨血运的破坏,其稳定性依赖于螺丝钉-接骨板组合的成角稳定性。带有锁定螺丝钉的新型微创固定系统(LISS)和锁定加压接骨板(LCP)可以为现代骨折手术治疗提供新的选择方法,是微创经皮接骨板技术(MIPO)的理想材料,并可以在疏松骨质内得到相当好的固定强度。然而,必须指出这些新型接骨板和螺丝钉并不能解决所有的问题,特别是在处理干骺端和骨干部骨折时,它们每一步的操作都需要有非常仔细的计划,包括重温AO经典的原则。Thomas P.Rüedi(托马斯.鲁迪) Christoph Sommer(克利斯托夫.邵墨) 罗炯 顾立强 2003中华创伤骨科杂志2003,5,3:169
2High-definition colonoscopy with i-Scan:Better diagnosis for small polyps and flat adenomas显示文摘AIM:To investigate if high-definition (HD) colonoscope with i-Scan gave a higher detection rate of mucosal lesions vs standard white-light instruments. METHODS:Data were collected from the computerized database of the endoscopy unit of our tertiary referral center. We retrospectively analyzed 1101 consecutive colonoscopies that were performed over 1 year with standard white-light (n = 849) or HD+ with i-Scan (n = 252) instruments by four endoscopists, in an outpatient setting. Colonoscopy records included patients' main details and family history for colorectal cancer, indication for colonoscopy (screening, diagnostic or surveillance), type of instrument used (standard white-light or HD+ plus i-Scan), name of endoscopist and bowel preparation. Records for each procedure included whether the cecum was reached or not and the reason for failure, complications during or immediately after the procedure, and number, size, location and characteristics of the lesions. Polyps or protrudinglesions were defined as sessile or pedunculated, and nonprotruding lesions were defined according to Paris classification. For each lesion, histological diagnosis was recorded. RESULTS:Eight hundred and forty-nine colonoscopies were carried with the standard white-light video colonoscope and 252 with the HD+ plus i-Scan video colonoscope. The four endoscopists did 264, 300, 276 and 261 procedures, respectively; 21.6%, 24.0%, 21.7% and 24.1% of them with the HD+ plus i-Scan technique. There were no significant differences between the four endoscopists in either the number of procedures done or the proportions of each imaging technique used. Both techniques detected one or more mucosal lesions in 522/1101 procedures (47.4%). The overall number of lesions recognized was 1266; 645 in the right colon and 621 in the left. A significantly higher number of colonoscopies recognized lesions in the HD+ plus i-Scan mode (171/252 = 67.9%) than with the standard white-light technique (408/849 = 48.1%) (P < 0.0001). HD+ with i-Scan colonoscopies identified more lesions than standard white-light imaging (459/252 and 807/849, P < 0.0001), in the right or left colon (mean ± SD, 1.62 ± 1.36 vs 1.33 ± 0.73, P < 0.003 and 1.55 ± 0.98 vs 1.17 ± 0.93, P = 0.033), more lesions < 10 mm (P < 0.0001) or nonprotruding (P < 0.022), and flat polyps (P = 0.04). The cumulative mean number of lesions per procedure detected by the four endoscopists was significantly higher with HD+ with i-Scan than with standard white-light imaging (1.82 ± 2.89vs 0.95 ± 1.35,P < 0.0001). CONCLUSION:HD imaging with i-Scan during the withdrawal phase of colonoscopy significantly increased the detection of colonic mucosal lesions, particularly small and nonprotruding polyps.Pier Alberto Testoni Chiara Notaristefano Cristian Vailati Milena Di Leo Edi Viale 2012World Journal of Gastroenterology2012,18,37:12
3Design and Implementation of Paired Pectoral Fins Locomotion of Labriform Fish Applied to a Fish Robot显示文摘In present,there are increasing interests in the research on mechanical and control system of underwater vehicles.Theseongoing research efforts are motivated by more pervasive applications of such vehicles including seabed oil and gas explorations,scientific deep ocean surveys,military purposes,ecological and water environmental studies,and also entertainments.However,the performance of underwater vehicles with screw type propellers is not prospective in terms of its efficiency andmaneuverability.The main weaknesses of this kind of propellers are the production of vortices and sudden generation of thrustforces which make the control of the position and motion difficult.On the other hand,fishes and other aquatic animals are efficient swimmers,posses high maneuverability,are able to followtrajectories,can efficiently stabilize themselves in currents and surges,create less wakes than currently used underwater vehicle,and also have a noiseless propulsion.The fish’s locomotion mechanism is mainly controlled by its caudal fin and paired pectoralfins.They are classified into Body and/or Caudal Fin(BCF)and Median and/or paired Pectoral Fins(MPF).The study of highlyefficient swimming mechanisms of fish can inspire a better underwater vehicles thruster design and its mechanism.There are few studies on underwater vehicles or fish robots using paired pectoral fins as thruster.The work presented in thispaper represents a contribution in this area covering study,design and implementation of locomotion mechanisms of pairedpectoral fins in a fish robot.The performance and viability of the biomimetic method for underwater vehicles are highlightedthrough in-water experiment of a robotic fish.Patar Ebenezer Sitorus Yul Yunazwin Nazaruddin Edi Leksono Agus Budiyono 2009Journal of Bionic Engineering2009,6,1:10
4Folic acid supplementation inhibits recurrence of colorectal adenomas:A randomized chemoprevention trial显示文摘AIM: To determine whether folic acid supplementation will reduce the recurrence of colorectal adenomas, the precursors of colorectal cancer, we performed a double-blind placebo-controlled trial in patients with adenomatous polyps. METHODS: In the current double-blind, placebo-controlled trial at this VA Medical Center, patients with colorectal adenomas were randomly assigned to receive either a daily 5 mg dose of folic acid or a matched identical placebo for 3 years. All polyps were removed at baseline colonoscopy and each patient had a follow up colonoscopy at 3 years. The primary endpoint was a reduction in the number of recurrent adenomas at 3 years. RESULTS: Of 137 subjects, who were eligible after confirmation of polyp histology and run-in period to conform compliance, 94 completed the study; 49 in folic acid group and 45 in placebo group. Recurrence of adenomas at 3-year was compared between the two groups. The mean number of recurrent polyps at 3-year was 0.36 (SD, 0.69) for folic acid treated patients compared to 0.82 (SD, 1.17) for placebo treated subjects, resulting in a 3-fold increase in polyp recurrence in the placebo group. Patients below 70 years of age and those with left-sided colonicadenomas or advanced adenomas responded better to folic acid supplementation. CONCLUSION: High dose folic acid supplementation is associated with a signif icant reduction in the recurrence of colonic adenomas suggesting that folic acid may be an effective chemopreventive agent for colorectal neoplasia.Richard Jaszewski Sabeena Misra Martin Tobi Nadeem Ullah Jo Ann Naumoff Omer Kucuk Edi Levi Bradley N Axelrod Bhaumik B Patel Adhip PN Majumdar 2008World Journal of Gastroenterology2008,14,28:10

6Cancer stem cells in Helicobacter pylori infection and aging: Implications for gastric carcinogenesis显示文摘AIM: To demonstrated the combined effects of aging and carcinogen treatment on cancer stem/stem-like cells(CSCs) of gastric mucosa in an animal model. METHODS: In this study we investigated the effects of aging and Helicobacter pylori(H. pylori) inflammation as a model for inflammation induced carcinogenesis in human and rat gastric mucosa samples. In aging studies, we compared 4-mo old(young) with 22 mo(aged) old Fischer-344 rats. For human studies, gastric biop-sies and resection specimens representing normal mucosa or different stages of H. pylori gastritis and gastric adenocarcinomas were used for determining the expression of stem cell markers CD166, ALDH1 and LGR5. In addition we performed immunofluorescent double labeling for B-catenin and Lgr5 in both rat and human gastric tissues to examine the status of Wnt signaling in these cells. RESULTS: CSC markers ALDH1, LGR5, and CD166 were expressed in very low levels in normal human gastric mucosa or young rat gastric mucosa. In contrast, level of expression for all three markers significantly increased in H. pylori gastritis and gastric adenocarcinomas as well as in normal gastric mucosa in aged rats. We also observed cytoplasmic B-catenin staining in both aged rat and human H. pylori inflamed gastric mucosa, which were found to be colocalized with Lgr5 immunoreactive cells. The increased number of ALDH1, CD166 and LGR5 positive cells in H. pylori gastritis indicates that increased number of stem-like cells in gastric mucosa is an early event, and may constitute an important step in the progression to neoplasia. CONCLUSION: Our observation of the age-related increase in cancer stem/stem-like cells in the gastric mucosa may explain the increased incidence of gastric cancer during aging. Combination of aging and H. pylori infection may have additive effects in progression to neoplasia.Edi Levi Paula Sochacki Nabiha Khoury Bhaumik B Patel Adhip PN Majumdar 2014World Journal of Gastrointestinal Pathophysiology2014,5,3:5

8Gut microbiome profiling and colorectal cancer in African Americans and Caucasian Americans显示文摘AIM To determine whether and to what extent the gut microbiome is involved in regulating racial disparity in colorectal cancer(CRC). METHODS All patients were recruited and experiments were performed in accordance with the relevant guidelines and regulations by the Institutional Review Boards (IRB), committees of the John D. Dingell VAMC and Wayne State University guidelines. African American (AA) and Caucasian American (CA) patients were scheduled for an outpatient screening for colonoscopy, and no active malignancy volunteer patients were doubly consented, initially by the gastroenterologist and later by the study coordinator, for participation in the study. The gut microbial communities in colonic effluents from AAs and CAs were examined using 16 sRNA profiling, and bacterial identifications were validated by performing SYBR-based Real Time PCR. For metagenomic analysis to characterize the microbial communities, multiple software/tools were used, including Metastats and R statistical software.RESULTS It is generally accepted that the incidence and mortality of CRC is higher in AAs than in CAs. However, the reason for this disparity is not well understood. We hypothesize that the gut microbiome plays a role in regulating this disparity. Indeed, we found significant differences in species richness and diversity between AAs and CAs. Bacteroidetes was more abundant in AAs than in CAs. In particular, the pro-inflammatory bacteria Fusobacterium nucleatum and Enterobacter species were significantly higher in AAs, whereas probiotic Akkermansia muciniphila and Bifidobacterium were higher in CAs. The polyphyletic Clostridia class showed a divergent pattern, with Clostridium XI elevated in AAs, and Clostridium IV, known for its beneficial function, higher in CAs. Lastly, the AA group had decreased microbial diversity overall in comparison to the CA group. In summary, there were significant differences in pro-inflammatory bacteria and microbial diversity between AA and CA, which may help explain the CRC disparity between groups.CONCLUSION Our current investigation, for the first time, demonstrates microbial dysbiosis between AAs and CAs, which could contribute to the racial disparity of CRC.Lulu Farhana Fadi Antaki Farhan Murshed Hamidah Mahmud Stephanie L Judd Pratima Nangia-Makker Edi Levi Yingjie Yu Adhip PN Majumdar 2018World Journal of Gastrointestinal Pathophysiology2018,9,2:3

10North-south difference of water mass properties across the Lembeh Strait, North Sulawesi, Indonesia显示文摘Two field observations were conducted around the Lembeh Strait in September 2015 and 2016, respectively.Evidences indicate that seawater around the Lembeh Strait is consisted of North Pacific Tropical Water(NPTW),North Pacific Intermediate Water(NPIW), North Pacific Tropical Intermediate Water(NPTIW) and Antarctic Intermediate Water(AAIW). Around the Lembeh Strait, there exist some north-south differences in terms of water mass properties. NPTIW is only found in the southern Lembeh Strait. Water mass with the salinity of 34.6 is only detected at 200–240 m between NPTW and NPTIW in the southern Lembeh Strait, and results from the process of mixing between the saltier water transported from the South Pacific Ocean and the lighter water from the North Pacific Ocean and Sulawesi Sea. According to the analysis on mixing layer depth, it is indicated that there exists an onshore surface current in the northern Lembeh Strait and the surface current in the Lembeh Strait is southward.These dramatic differences of water masses demonstrate that the less water exchange has been occurred between the north and south of Lembeh Strait. In 2015, the positive wind stress curl covering the northern Lembeh Strait induces the shoaling of thermocline and deepening of NPIW, which show that the north-south difference of airsea system is possible of inducing north-south differences of seawater properties.WANG Weibo PAN Aijun EDI Kusmanto MUH Hasanudin DENY Sutisna 2018Acta Oceanologica Sinica2018,37,12:2
11Modification of Oil Palm Empty Fruit Bunch and Sugarcane Bagasse Biomass as Potential Reinforcement for Composites Panel and Thermal Insulation Materials显示文摘This paper focuses on the study of the effect of modification of Oil Palm Empty Fruit Bunch(OPEFB)and sugarcane bagasse(SCB)biomass as potential reinforcement for composites panel and thermal insulation.Both fibres were treated with three types of chemicals:2%silane,4%H2O2 and 4%H2O2-2%silane for 3 h.The influence of modified fibres content in composites was examined by structural changes using image analyser,Fourier transform infrared(FTIR),Scanning Electron Microscopy(SEM),tensile,interracial shear strength(IFSS)and thermal characteristic.The diameter of both fibres was reduced after treatment and showed decreasing of lignin and hemi-cellulose in fibre.Tensile strength has been increased by 2%silane treatment for both fibres and 4%H2O2 treatment displays higher result for IFSS.Thermal properties of treated SCB fibre with silane display higher residual content and better thermal stability.SEM charac-terization showed that 2%silane treatment removed silica bodies of OPEFB fibre while 4%H2O2 treatment uniformly filled porosity of SCB fibre.Finally,results revealed that treated OPEFB fibre is enough to improve compatibility and mechanical properties,while treated SCB fibre was effective in thermal stability for fabrication of composite materials.Nor Azlina Ramlee Mohammad Jawaid Edi Syams Zainudin Shaikh Abdul Karim Yamani 2019Journal of Bionic Engineering2019,16,1:2

13Analysis of Turbulence and Surface Growth Models on the Estimation of Soot Level in Ethylene Non-Premixed Flames显示文摘Soot prediction in a combustion system has become a subject of attention, as many factors influence its accuracy. An accurate temperature prediction will likely yield better soot predictions, since the inception, growth and destruction of the soot are affected by the temperature. This paper reported the study on the influences of turbulence closure and surface growth models on the prediction of soot levels in turbulent flames. The results demonstrated that a substantial distinction was observed in terms of temperature predictions derived using the k-ε and the Reynolds stress models, for the two ethylene flames studied here amongst the four types of surface growth rate model investigated, the assumption of the soot surface growth rate proportional to the particle number density, but independent on the surface area of soot particles, f(A_s) = ρN_s, yields in closest agreement with the radial data. Without any adjustment to the constants in the surface growth term, other approaches where the surface growth directly proportional to the surface area and square root of surface area, f(A_s) = A_s and f(A_s) = √A_s, result in an under-prediction of soot volume fraction. These results suggest that predictions of soot volume fraction are sensitive to the modelling of surface growth.Y.Yunardi Edi Munawar Wahyu Rinaldi Asbar Razali Elwina Iskandar M.Fairweather 2018Journal of Thermal Science2018,27,1:2
