| 1 | 东准噶尔盆地巴塔玛依内山组火山岩锆石U-Pb年代及Hf同位素研究显示文摘对准噶尔盆地陆梁隆起东部三参1井所钻巴塔玛依内山组玄武岩,开展了详细锆石内部结构研究基础上的U-Pb年代学、微量元素和Hf同位素系统分析.结果显示,所有锆石都属岩浆成因,都有一致的稀土配分型式,都具明显的Ce正异常(δCe=5.06~134)、Eu负异常(δEu=0.06~0.55)和重稀土元素富集特征.25颗锆石中,谐和年龄主要分成3组,分别是(300.4±1.3)Ma(n=11),(339.2±2.7)Ma(n=3)和(392.0±1.7)Ma(n=8);此外,还有3颗近谐和年龄锆石,它们的206Pb/238U年龄分别是(510±7),(488±6)和(453±6)Ma.最小的谐和年龄为(300.4±1.3)Ma,可以代表巴塔玛依内山组火山岩的形成时代(如晚阶段年龄).其他年龄如早泥盆世、奥陶纪等,与盆地周缘岛弧火山岩(富集Pb)和蛇绿岩的时代一致,而且这些年龄锆石都具有正的εHf(t)值(+3.6^+10.5),推测所研究火山岩穿越的盆地基底,可能与由早古生代-中古生代的残余洋壳和岛弧地体组成有关.晚石炭世锆石的εHf(t)值变化于+17.1^+4.2,显示该玄武岩主要来源于软流圈地幔或亏损岩石圈地幔熔融作用,熔体在上升-侵位过程中混染了少量较古老基底物质组分.由于这些玄武岩是后碰撞幔源岩浆直接加入到地壳的物质表现,推测东准噶尔地区晚石炭世已经有了大规模的陆壳垂向生长过程. | 苏玉平 郑建平 Griffin William L 汤华云 O'Reilly Suzanne Y 林向洋 | 2010 | 科学通报2010,55,30: | 50 |

| 6 | Performance characterization of Ni60-WC coating on steel processed with supersonic laser deposition显示文摘Ni60-WC particles are used to improve the wear resistance of hard-facing steel due to their high hardness. An emerging technology that combines laser with cold spraying to deposit the hard-facing coatings is known as supersonic laser deposition. In this study, Ni60-WC is deposited on low-carbon steel using SLD. The microstructure and performance of the coatings are investigated through SEM, optical microscopy, EDS, XRD, microhardness and pin-on-disc wear tests. The experimental results of the coating processed with the optimal parameters are compared to those of the coating deposited using laser cladding. | Fang LUO Andrew COCKBURN Martin SPARKES Rocco LUPOI Zhi-jun CHEN William O'NEILL Jian-hua YAO Rong LIU | 2015 | Defence Technology(防务技术)2015,11,1: | 11 |
| 7 | Passive expansion of sub-maximally dilated transjugular intrahepatic portosystemic shunts and assessment of clinical outcomes显示文摘AIM To assess for passive expansion of sub-maximally dilated transjugular intrahepatic portosystemic shunts(TIPS) and compare outcomes with maximally dilated TIPS.METHODS Polytetrafluoroethylene covered TIPS(Viatorr) from July 2002 to December 2013 were retrospectively reviewed at two hospitals in a single institution. Two hundred and thirty patients had TIPS maximally dilated to 10 mm(m TIPS), while 43 patients who were at increased risk for hepatic encephalopathy(HE), based on clinical evaluation or low pre-TIPS portosystemic gradient(PSG), had 10 mm TIPS sub-maximally dilated to 8 mm(sm TIPS). Group characteristics(age, gender, Model for End-Stage Liver Disease score, post-TIPS PSG and clinical outcomes were compared between groups, including clinical success(ascites or varices), primary patency,primary assisted patency, and severe post-TIPS HE. A subset of fourteen patients with sm TIPS underwent follow-up computed tomography imaging after TIPS creation, and were grouped based on time of imaging(< 6 mo and > 6 mo). Change in diameter and crosssectional area were measured with 3D imaging software to evaluate for passive expansion.RESULTS Patient characteristics were similar between the sm TIPS and m TIPS groups, except for pre-TIPS portosystemic gradient, which was lower in the sm TIPS group(19.4 mm Hg ± 6.8 vs 22.4 mm Hg ± 7.1, P = 0.01). Primary patency and primary assisted patency between sm TIPS and m TIPS was not significantly different(P = 0.64 and 0.55, respectively). Four of the 55 patients(7%) with sm TIPS required TIPS reduction for severe refractory HE, while this occurred in 6 of the 218 patients(3%) with m TIPS(P = 0.12). For the 14 patients with follow-up computed tomography(CT) imaging, the median imaging follow-up was 373 d. There was an increase in median TIPS diameter, median percent diameter change, median area, and median percent area change in patients with CT follow-up greater than 6 mo after TIPS placement compared to follow-up within 6 mo(8.45 mm, 5.58%, 56.04 mm^2, and 11.48%, respectively, P = 0.01).CONCLUSION Passive expansion of sm TIPS does occur but clinical outcomes of sm TIPS and m TIPS were similar. Sub-maximal dilation can prevent complications related to overshunting in select patients. | Michael C Hsu Charles N Weber S William Stavropoulos Timothy W Clark Scott O Trerotola Richard D Shlansky Goldberg Michael C Soulen Gregory J Nadolski | 2017 | World Journal of Hepatology2017,9,12: | 11 |
| 8 | Pre-and postoperative systemic hemodynamic evaluation in patients subjected to esophagogastric devascularization plus splenectomy and distal splenorenal shunt:A comparative study in schistomomal portal hypertension显示文摘AIM: To investigate the systemic hemodynamic effects of two surgical procedures largely employed for treatment of schistosomal portal hypertension. METHODS: Thirty-six patients undergoing elective surgical treatment of portal hypertension due to hepatosplenic mansonic schistosomiasis were prospectively evaluated. All patients were subjected to preoperative pulmonary artery catheterization; 17 were submitted to esophagogastric devascularization and splenectomy (EGDS) and 19 to distal splenorenal shunt (DSRS). The systemic hemodynamic assessment was repeated 4 d after the surgical procedure. RESULTS: Preoperative evaluation revealed (mean ± SD) an increased cardiac index (4.78 ± 1.13 L/min per m2),associated with a reduction in systemic vascular resistance index (1457 ± 380.7 dynes.s/cm5.m2). The mean pulmonary artery pressure (18 ± 5.1 mmHg) as well as the right atrial pressure (7.9 ± 2.5 mmHg) were increased,while the pulmonary vascular resistance index (133 ± 62 dynes.s/cm5.m2) was decreased. Four days after EGDS,a significant reduction in cardiac index (3.80 ± 0.4 L/min per m2,P < 0.001) and increase in systemic vascular resistance index (1901.4 ± 330.2 dynes.s/cm5. m2,P < 0.001) toward normal levels were observed. There was also a significant reduction in pulmonary artery pressure (12.65 ± 4.7 mmHg,P < 0.001) and no significant changes in the pulmonary vascular resistance index (141.6 ± 102.9 dynes.s/cm5.m2). Four days after DSRS,a non-significant increase in cardiac index (5.2 ± 0.76 L/min per m2) and systemic vascular resistance index (1389 ± 311 dynes.s/cm5.m2) was observed. There was also a non-significant increase in pulmonary artery pressure (19.84 ± 5.2 mmHg),right cardiac work index (1.38 ± 0.4 kg.m/m2) and right ventricular systolic work index (16.3 ± 6.3 g.m/m2),without significant changes in the pulmonary vascular resistance index (139.7 ± 67.8 dynes.s/cm5.m2). CONCLUSION: The hyperdynamic circulatory state observed in mansonic schistosomiasis was corrected by EGDS,but was maintained in patients who underwent DSRS. Similarly,the elevated mean pulmonary artery pressure was corrected after EGDS and maintained after DSRS. EGDS seems to be the most physiologic surgery for patients with schistosomal portal hypertension. | Roberto de Cleva Paulo Herman Luis Augusto Carneiro D’albuquerque Vincenzo Pugliese Orlando Luis Santarem William Abro Saad | 2007 | World Journal of Gastroenterology2007,13,41: | 9 |
| 9 | Hardfacing steel with nanostructured coatings of Stellite-6 by supersonic laser deposition显示文摘The ability to manufacture coatings is critical to engineering design. Many components require the application of additional layers toenhance mechanical properties and protect against hostile environments. Supersonic laser deposition (SLD) is a novel coating methodbased on cold spray (CS) principles. In this technique, the deposition velocities can be significantly lower than those required foreffective bonding in CS applications. The addition of laser heat energy permits a change in the thermodynamic experience of impactingparticles, thereby offering a greater opportunity for efficient bonding at lower velocities as compared with the CS process. The workreported in this paper demonstrates the ability of the SLD process to deliver hardfacing materials to engineering surfaces. Stellite-6 hasbeen deposited on low-carbon steel tubes over a range of process parameters to establish the appropriate target power and traversespeeds for the coating formation. The coating properties and parameters were examined to determine the primary characteristics andgrain structure size. Their morphology and performance were studied through optical microscopy, scanning electron microscope(SEM), X-ray diffraction, hardness measurements and wear testing. The results have shown that SLD is capable of depositing layers ofStellite-6, with properties that are superior to those of their conventionally manufactured counterparts. | Rocco Lupoi Andrew Cockburn Chris Bryan Martin Sparkes Fang Luo William O’Neill | 2012 | Light(Science & Applications)2012,1,1: | 8 |
| 10 | Macrophage inhibitory cytokine-1/growth differentiation factor-15 in premalignant and neoplastic tumours in a high-risk pancreatic cancer cohort显示文摘BACKGROUND Pancreatic cancer(PC)is a leading cause of cancer related mortality worldwide,with poor survival due to late diagnosis.Currently,biomarkers have limited use in early diagnosis of PC.Macrophage inhibitory cytokine-1 or growth differentiation factor-15(MIC-1/GDF15)has been implicated as a potential serum biomarker in PC and other malignancies.AIM To determine the role of MIC-1/GDF15 in detecting pre-malignant pancreatic lesions and neoplastic tumours in an asymptomatic high-risk cohort part of Australian Pancreatic Cancer Screening Program.METHODS A feasibility prospective single centre cohort study was performed.Participants recruited for yearly surveillance with endoscopic ultrasound(EUS)had serial fasting blood samples collected before EUS for MIC-1/GDF15,C-reactive protein and carbohydrate antigen 19-9.Patients were stratified into five groups based on EUS findings:Normal;pancreatic cysts,branch-duct intraductal papillary mucinous neoplasm;diffuse non-specific abnormalities;and neoplastic tumours.MIC-1/GDF15 serum levels were quantified using ELISA.Participants in whom EUS demonstrated abnormalities but not malignancy were closely followed up with magnetic resonance imaging(MRI)or computed tomography.RESULTS One hundred twenty participants were prospectively recruited from 2011-2018.Forty-seven participants(39.2%)had an abnormal EUS and five participants(4.2%)were diagnosed with neoplastic tumours,three by EUS(two pancreatic and one liver)and two by MRI/computed tomography(breast cancer,bladder cancer),which were performed for follow up of abnormal EUS.Baseline serum MIC-1/GDF15 was a significant predictor of neoplastic tumours on receiver operator characteristic curve analysis[area under curve(AUC)=0.814,P=0.023].Baseline serum MIC-1/GDF15 had moderate predictive capacity for branch-duct intraductal papillary mucinous neoplasm(AUC=0.644)and neoplastic tumours noted on EUS(AUC=0.793),however this was not significant(P=0.188 and 0.081 respectively).Serial serum MIC-1/GDF15 did not demonstrate a significant percentage change between a normal and abnormal EUS(P=0.213).Median baseline MIC-1/GDF15 was greater in those with neoplastic tumours(Median=1039.6,interquartile range=727.0-1977.7)compared to those diagnosed with a benign lesion(Median=570.1,interquartile range=460.7-865.2)on EUS and MRI(P=0.012).CONCLUSION In this pilot study MIC-1/GDF15 has predictive capacity for neoplastic tumours in asymptomatic individuals with a genetic predisposition for PC.Further imagining may be warranted in patients with abnormal EUS and raised serum MIC-1/GDF15.Larger multicentric prospective studies are required to further define the role of MIC-1/GDF15 as a serological biomarker in pre-malignant pancreatic lesions and neoplastic tumours. | Robert Sean O’Neill Sam Emmanuel David Williams Alina Stoita | 2020 | World Journal of Gastroenterology2020,26,14: | 8 |

| 14 | Endoscopic balloon catheter dilatation via retrograde or static technique is safe and effective for cricopharyngeal dysfunction显示文摘AIM To evaluate the safety and efficacy of upper esophageal sphincter(UES) dilatation for cricopharyngeal(CP) dysfunction. To determine if:(1) indication for dilatation; or(2) technique of dilatation correlated with symptom improvement.METHODS All balloon dilatations performed at our institution from over a 3-year period were retrospectively analyzed for demographics, indication and dilatation site. All dilatations involving the UES underwent further review to determine efficacy, complications, and factors that predict success. Dilatation technique was separated into static(stationary balloon distention) and retrograde(brusque pull-back of a fully distended balloon across the UES).RESULTS Four hundred and eighty-eight dilatations were reviewed. Thirty-one patients were identified who underwent UES dilatation. Median age was 63 years(range 27-81)and 55% of patients were male. Indications included dysphagia(28 patients), globus sensation with evidence of UES dysfunction(2 patients) and obstruction to echocardiography probe with cricopharyngeal(CP)bar(1 patient). There was evidence of concurrent oropharyngeal dysfunction in 16 patients(52%) and a small Zenker's diverticula(≤ 2 cm) in 7 patients(23%). Dilator size ranged from 15 mm to 20 mm. Of the 31 patients, 11 had dilatation of other esophageal segments concurrently with UES dilatation and 20 had UES dilatation alone.Follow-up was available for 24 patients for a median of 2.5 mo(interquartile range 1-10 mo), of whom 19 reported symptomatic improvement(79%). For patients undergoing UES dilatation alone, follow-up was available for 15 patients, 12 of whom reported improvement(80%).Nineteen patients underwent retrograde dilatation(84%response) while 5 patients had static dilatation(60%response); however, there was no significant difference in symptom improvement between the techniques(P = 0.5).Successful symptom resolution was also not significantly affected by dilator size, oropharyngeal dysfunction,Zenker's diverticulum, age or gender(P > 0.05). The only complication noted was uvular edema and a shallow ulcer after static dilatation in one patient, which resolved spontaneously and did not require hospital admission.CONCLUSION UES dilatation with a through-the-scope balloon by either static or retrograde technique is safe and effective for the treatment of dysphagia due to CP dysfunction. To our knowledge, this is the first study evaluating retrograde balloon dilatation of the UES. | Vinay Chandrasekhara Joyce Koh Lakshmi Lattimer Kerry B Dunbar William J Ravich John O Clarke | 2017 | World Journal of Gastrointestinal Endoscopy2017,9,4: | 6 |
| 15 | LRP6 in mesenchymal stem cells is required for bone formation during bone growth and bone remodeling显示文摘Lipoprotein receptor-related protein 6(LRP6) plays a critical role in skeletal development and homeostasis in adults. However, the role of LRP6 in mesenchymal stem cells(MSCs), skeletal stem cells that give rise to osteoblastic lineage, is unknown. In this study, we generated mice lacking LRP6 expression specifically in nestin1MSCs by crossing nestin-Cre mice with LRP6floxmice and investigated the functional changes of bone marrow MSCs and skeletal alterations. Mice with LRP6 deletion in nestin1cells demonstrated reductions in body weight and body length at 1 and 3 months of age. Bone architecture measured by microCT(mCT) showed a significant reduction in bone mass in both trabecular and cortical bone of homozygous and heterozygous LRP6mutant mice. A dramatic reduction in the numbers of osteoblasts but much less significant reduction in the numbers of osteoclasts was observed in the mutant mice. Osterix1osteoprogenitors and osteocalcin1osteoblasts significantly reduced at the secondary spongiosa area, but only moderately decreased at the primary spongiosa area in mutant mice. Bone marrow MSCs from the mutant mice showed decreased colony forming, cell viability and cell proliferation. Thus, LRP6 in bone marrow MSCs is essential for their survival and proliferation, and therefore, is a key positive regulator for bone formation during skeletal growth and remodeling. | Changjun Li Bart O Williams Xu Cao Mei Wan | 2014 | Bone Research2014,2,1: | 6 |
| 16 | Archaea and the human gut:New beginning of an old story显示文摘Methanogenic archaea are known as human gut inhabitants since more than 30 years ago through the detection of methane in the breath and isolation of two methanogenic species belonging to the order Methanobacteriales,Methanobrevibacter smithii and Methanosphaera stadtmanae.During the last decade,diversity of archaea encountered in the human gastrointestinal tract(GIT)has been extended by sequence identification and culturing of new strains.Here we provide an updated census of the archaeal diversity associatedwith the human GIT and their possible role in the gut physiology and health.We particularly focus on the still poorly characterized 7th order of methanogens,the Methanomassiliicoccales,associated to aged population.While also largely distributed in non-GIT environments,our actual knowledge on this novel order of methanogens has been mainly revealed through GIT inhabitants.They enlarge the number of final electron acceptors of the gut metabolites to mono-di-and trimethylamine.Trimethylamine is exclusively a microbiota-derived product of nutrients(lecithin,choline,TMAO,L-carnitine)from normal diet,from which seems originate two diseases,trimethylaminuria(or Fish-Odor Syndrome)and cardiovascular disease through the proatherogenic property of its oxidized liver-derived form.This therefore supports interest on these methanogenic species and its use as archaebiotics,a term coined from the notion of archaea-derived probiotics. | Nadia Gaci Guillaume Borrel William Tottey Paul William O’Toole Jean-Fran?ois Brugère | 2014 | World Journal of Gastroenterology2014,20,43: | 5 |
