| 2 | A deep convolutional neural network for real-time full profile analysis of big powder diffraction data显示文摘We present Parameter Quantification Network(PQ-Net),a regression deep convolutional neural network providing quantitative analysis of powder X-ray diffraction patterns from multi-phase systems.The network is tested against simulated and experimental datasets of increasing complexity with the last one being an X-ray diffraction computed tomography dataset of a multi-phase Ni-Pd/CeO_(2)-ZrO_(2)/Al_(2)O_(3) catalytic material system consisting of ca.20,000 diffraction patterns.It is shown that the network predicts accurate scale factor,lattice parameter and crystallite size maps for all phases,which are comparable to those obtained through full profile analysis using the Rietveld method,also providing a reliable uncertainty measure on the results.The main advantage of PQNet is its ability to yield these results orders of magnitude faster showing its potential as a tool for real-time diffraction data analysis during in situ/operando experiments. | Hongyang Dong Keith T.Butler Dorota Matras Stephen W.T.Price Yaroslav Odarchenko Rahul Khatry Andrew Thompson Vesna Middelkoop Simon D.M.Jacques Andrew M.Beale Antonis Vamvakeros | 2021 | npj Computational Materials2021,,1: | 5 |
| 3 | Extreme gastric dilation caused by chronic lead poisoning: A case report显示文摘Lead is a toxic metal that affects many organ systems and functions in humans. In the majority of adults, chronic lead poisoning comes from exposures to work places and can occur in numerous work settings, such as manufacturing, lead smelting and refinement, or due to use of batteries, pigments, solder, ammunitions, paint, car radiators, cable and wires, certain cosmetics. In some countries, lead is added to petrol. We present a rare case of gastric dilation caused by long-term petrol ingestion. A 16-year-old young man was admitted to our hospital due to a 6-mo history of exhaustion, dizziness, nausea, abdominal cramps and constipation. X-ray examination revealed dilated stomach descending into the pelvis and small bowel distension. After a long clinical observation, we found that the reason for the chronic lead poisoning of the patient was due to a 3-year history of petrol ingestion. The patient spontaneously recovered and stomach returned to its normal position and size. Lead poisoning should be taken into consideration in all unexplained cases of gastric dilation. | Vesna Begovic Darko Nozic Srdjan Kupresanin Dino Tarabar | 2008 | World Journal of Gastroenterology2008,14,16: | 4 |
| 4 | Plasma chitinase 3-like 1 is persistently elevated during first month after minimally invasive colorectal cancer resection显示文摘AIM: To assess blood chitinase 3-like 1(CHi3L1) levels for 2 mo after minimally invasive colorectal resection(MICR) for colorectal cancer(CRC). METHODS: CRC patients in an Institutional Review Board approved data/plasma bank who underwent elective MICR for whom preoperative(PreO p), early postoperative(PostO p), and 1 or more late PostO p samples [postoperative day(POD) 7-27] available were included. Plasma CHi3L1 levels(ng/m L) were determined in duplicate by enzyme linked immunosorbent assay. RESULTS: PreOp and PostOp plasma sample were available for 80 MICR cancer patients for the study. The median PreOp CHi3L1 level was 56.8 CI: 41.9-78.6 ng/mL(n = 80). Significantly elevated(P < 0.001) median plasma levels(ng/mL) over PreOp levels were detected on POD1(667.7 CI: 495.7, 771.7; n = 79), POD 3(132.6 CI: 95.5, 173.7; n = 76), POD7-13(96.4 CI: 67.7, 136.9; n = 62), POD14-20(101.4 CI: 80.7, 287.4; n = 22), and POD 21-27(98.1 CI: 66.8, 137.4; n = 20, P = 0.001). No significant difference in plasma levels were noted on POD27-41. CONCLUSION: Plasma CHi3L1 levels were significantly elevated for one month after MICR. Persistently elevated plasma CHi3L1 may support the growth of residual tumor and metastasis. | HMC Shantha Kumara David Gaita Hiromichi Miyagaki Xiaohong Yan Sonali AC Hearth Linda Njoh Vesna Cekic Richard L Whelan | 2016 | World Journal of Gastrointestinal Oncology2016,8,8: | 4 |

| 6 | Carcinosarcoma of the stomach:A case report and review of the literature显示文摘Carcinosarcomas are rare,malignant,biphasic tumors. We report the case of a 62-year-old man with gastric carcinosarcoma,along with its clinical,macroscopic and histopathological features. Macroscopically,a specimen of deformed stomach was obtained that measured 200 mm×150 mm×100 mm. A 150 mm×100 mm× 50 mm exophytic tumoral mass (Borrmann typeⅠ) was found,which involved the posterior wall from the cardia to the antrum. Histopathologically,a mixed type of malignancy was revealed: an adenocarcinoma with intestinal metaplasia,with interposed fascicles of fusiform atypical cells and numerous large,rounded and oval cells. The tumor showed positive histochemistry for cytokeratin 18,epithelial membrane antigen,carcinoembryonic antigen,chromogranin A and vimentin. Liver metastases were diagnosed 8 mo postoperatively,and the patient died 4 mo later. A review of the available literature is also presented. | Tomislav Randjelovic Branka Filipovic Darko Babic Vesna Cemerikic Branislav Filipovic | 2007 | World Journal of Gastroenterology2007,13,41: | 3 |
| 7 | Low-dose tenofovir is more potent than adefovir and is effective in controlling HBV viremia in chronic HBeAg-negative hepatitis B显示文摘AIM: To study the efficacy of tenofovir disoproxil fumarate (TDF) at low dose in a small open trial of chronic hepatitis B patients with advanced stage disease. METHODS: Eleven patients were treated with TDF 75 mg for a median period of 80 (range, 24-576) wk and then 7 cases were shifted to an adefovir 10 mg treatment group. All patients had been pre-treated with lamivudine: 5 had YMDD resistant mutants and 6 wild- type virus. When TDF was started, 4 patients had low- level viremia and 6 were PCR-negative. RESULTS: During TDF treatment, PCR remained negative in 10 patients, transaminase levels were normal and no significant viral breakthrough was observed. The drug was well tolerated in all cases. When TDF 75 mg was substituted with adefovir 10 mg, 3 out of 7 patients had a persistent viral rebound (2700-130 000 copies/mL), in whom lamivudine had to be reintroduced. CONCLUSION: Low-dose TDF monotherapy can control HBV viremia for an extended period of time without the emergence of resistance and is more potent than adefovir at the standard dosage. The use of a reduced dose of TDF could diminish the cost of therapy in low-income countries, but further studies in a larger population and in HBeAg-positive subjects are needed. | Paolo Del Poggio Maurizio Zaccanelli Maria Oggionni Silvia Colombo Carlo Jamoletti Vesna Puhalo | 2007 | World Journal of Gastroenterology2007,13,30: | 3 |

| 10 | Plasma MMP-2 and MMP-7 levels are elevated first month after surgery and may promote growth of residual metastases显示文摘BACKGROUND MMP-2 also known as gelatinase A and MMP-7(matrilysin)are members of the zinc-dependent family of MMPs(Matrix metalloproteinase).MMP-2 and MMP-7 are remodeling enzymes that digest extracellular matrix;MMP-2 is extensively expressed during development and is upregulated at sites of tissue damage,inflammation,and in stromal cells of metastatic tumors.MMP-7 is expressed in the epithelial cells and in a variety of cancers including colon tumors.Plasma MMP-2 and MMP-7 levels were assessed before and after minimally invasive colorectal resection for cancer pathology.AIM To determine plasma MMP-2 and MMP-7 levels before and after minimally invasive colorectal resection for cancer pathology.METHODS Patients enrolled in a plasma bank for whom plasma was available were eligible.Plasma obtained from preoperative(Preop)and postoperative blood samples was used.Only colorectal cancer(CRC)patients who underwent elective minimally invasive cancer resection with preop,post-operative day(POD)1,3 and at least 1 late postop sample(POD 7-34)were included.Late samples were bundled into 7 d blocks(POD 7-13,14-20,etc.)and treated as single time points.Plasma MMP-2 and MMP-7 levels were determined via enzyme-linked immunosorbent assay in duplicate.RESULTS Total 88 minimally invasive CRC resection CRC patients were studied(right colectomy,37%;sigmoid,24%;and LAR/AR 18%).Cancer stages were:1,31%;2,30%;3,34%;and 4,5%.Mean Preop MMP-2 plasma level(ng/mL)was 179.3±40.9(n=88).Elevated mean levels were noted on POD1(214.3±51.2,n=87,P<0.001),POD3(258.0±63.9,n=80,P<0.001),POD7-13(229.9±62.3,n=65,P<0.001),POD 14-20(234.9±47.5,n=25,P<0.001),POD 21-27(237.0±63.5,n=17,P<0.001,)and POD 28-34(255.4±59.7,n=15,P<0.001).Mean Preop MMP-7 level was 3.9±1.9(n=88).No significant differences were noted on POD 1 or 3,however,significantly elevated levels were noted on POD 7-13(5.7±2.5,n=65,P<0.001),POD 14-20(5.9±2.5,n=25,P<0.001),POD 21-27(6.1±3.6,n=17,P=0.002)and on POD 28-34(6.8±3.3,n=15 P<0.001,)vs preop levels.CONCLUSION MMP-2 levels are elevated for 5 wk and MMP-7 levels elevated for weeks 2-6.The etiology of these changes in unclear,trauma and wound healing likely play a role.These changes may promote residual tumor growth and metastasis. | HMC Shantha Kumara Hiromichi Miyagaki Sajith A Herath Erica Pettke Xiaohong Yan Vesna Cekic Richard L Whelan | 2021 | World Journal of Gastrointestinal Oncology2021,13,8: | 3 |
| 11 | 铝对玉米生长和硝酸还原酶活性的影响显示文摘测定了生长在Al2(SO4)100μmol/L氮素营养液中的两个玉米品种(SC704和VA35的根系和叶片)的NADH-硝酸还原酶(EC1.6.6.)和NAD(P)H-硝酸还原酶(EC1.6.6.2)活性。结果表明铝的存在阻碍了玉米根系和叶片的生长、降低了营养液的pH值,降低了叶片的NADH-及NAD(P)H-硝酸还原酶活性(酶活性降低的程度SC704低于VA35),增加了根系的NADH-和NAD(P)H-硝酸还原酶活性(VA35根系的比活性除外)。铝胁迫下根系的NADH-和NAD(P)H-硝酸还原酶活性的增加SC704大于VA35。耐铝品种SC704的高NR活性以及在铝胁迫下能维持更高的NR活性的特点说明硝酸还原酶与植物组织的Al解毒机制有关。同时,在铝胁迫下的硝酸盐代谢中NAD(P)H-硝酸还原酶具有更重要的作用。 | 刘保国 Vesna Hadzi-Taskovic Sukalovic | 1998 | 植物生理学报(0257-4829)1998,24,4: | 3 |

| 14 | Crosstalk between dietary patterns,obesity and nonalcoholic fatty liver disease显示文摘The prevalence of nonalcoholic fatty liver disease(NAFLD)is rising worldwide,paralleling the epidemic of obesity.The liver is a key organ for the metabolism of proteins,fats and carbohydrates.Various types of fats and carbohydrates in isocaloric diets differently influence fat accumulation in the liver parenchyma.Therefore,nutrition can manage hepatic and cardiometabolic complications of NAFLD.Even moderately reduced caloric intake,which leads to a weight loss of 5%-10%of initial body weight,is effective in improving liver steatosis and surrogate markers of liver disease status.Among dietary patterns,the Mediterranean diet mostly prevents the onset of NAFLD.Furthermore,this diet is also the most recommended for the treatment of NAFLD patients.However,clinical trials based on the dietary interventions in NAFLD patients are sparse.Since there are only a few studies examining dietary interventions in clinically advanced stages of NAFLD,such as active and fibrotic steatohepatitis,the optimal diet for patients in these stages of the disease must still be determined.In this narrative review,we aimed to critically summarize the associations between different dietary patterns,obesity and prevention/risk for NAFLD,to describe specific dietary interventions’impacts on liver steatosis in adults with NAFLD and to provide an updated overview of dietary recommendations that clinicians potentially need to apply in their daily practice. | Danijela Ristic-Medic Joanna Bajerska Vesna Vucic | 2022 | World Journal of Gastroenterology2022,28,27: | 2 |
| 15 | 通过轧制纯铝箔和阳极铝箔制备多层铝基复合材料(英文)显示文摘介绍了一种以商业纯铝箔为基体的多层复合材料的加工过程、组织结构和力学性能。采用热轧制交替排布的纯铝和阳极铝箔制备多层复合材料;此外,采用同样的工艺制备纯铝箔多层复合材料。在这两种情况下,均得到紧实致密的多层复合材料。为了研究复合材料的微观组织演变和力学性能,分别进行了光学和扫描电镜(SEM)、能谱(EDS)、X射线衍射(XRD)分析以及硬度、拉伸和三点弯曲试验。微观组织表征显示,阳极铝复合材料铝基体中平行分布着棒状Al_2O_3颗粒,而且铝箔界面间生成少量粗大颗粒。两种复合材料的硬度、强度、弹性模量和抗弯强度均高于纯铝材料的,而延展性明显降低。与纯铝箔多层复合材料相比,阳极铝箔多层复合材料具有较高的强度和弹性模量以及较低的延展性。材料的断裂失效方式与延展性的变化一致。 | Milan T.JOVANOVI?

| 16 | 不同电解条件下制备铜粉的形貌及结晶学比较分析(英文)显示文摘研究不同析氢条件下恒电位电解法制备铜粉的过程。采用扫描电镜(SEM)、X射线衍射(XRD)、粒度分布(PSD)和比表面积测定(SSA)对铜粉进行表征。根据电解过程析氢量的大小,形成树枝状和菜花状两种类型的颗粒。当析氢量大到足以对近电极层中的流体动力学条件产生强烈影响时,形成菜花状颗粒,否则形成树枝状颗粒。虽然颗粒的宏观结构差异很大,但他们的微观结构却相似,也就是说,这两种颗粒在微观层面上都是由近似球形的Cu颗粒小团聚体组成;球状形貌的存在是造成两种颗粒中Cu晶粒随机取向的原因。菜花样颗粒的比表面积是树枝状颗粒的3倍以上,其粒径则比树枝状颗粒的小很多。由此可见,强析氢条件对于铜粉制备是有益的。 | Nebojsa D.
