| 1 | Metal Fabrication by Additive Manufacturing Using Laser and Electron Beam Melting Technologies显示文摘Selective laser melting (SLM) and electron beam melting (EBM) are relatively new rapid, additive manufac- turing technologies which can allow for the fabrication of complex, multi-functional metal or alloy monoliths by CAD-directed, selective melting of precursor powder beds. By altering the beam parameters and scan strategies, new and unusual, even non-equilibrium microstructures can be produced; including controlled microstructural architectures which ideally extend the contemporary materials science and engineering paradigm relating structure-properties-processing-performance. In this study, comparative examples for SLM and EBM fabricated components from pre-alloyed, atomized precursor powders are presented. These include Cu, Ti–6Al–4V, alloy 625 (a Ni-base superalloy), a Co-base superalloy, and 17-4 PH stainless steel. These systems are characterized by optical metallography, scanning and transmission electron microscopy, and X-ray diffraction. | Lawrence E. Murr Sara M. Gaytan Diana A.

| 2 | Literature review on the management of diabetic foot ulcer显示文摘Diabetic foot ulcer(DFU) is the most costly and devastating complication of diabetes mellitus, which affect 15% of diabetic patients during their lifetime.Based on National Institute for Health and Clinical Excellence strategies, early effective management of DFU can reduce the severity of complications such as preventable amputations and possible mortality, and also can improve overall quality of life. The management of DFU should be optimized by using a multidisciplinary team, due to a holistic approach to wound management is required. Based on studies, blood sugar control, wound debridement, advanced dressings and offloading modalities should always be a part of DFU management. Furthermore, surgery to heal chronic ulcer and prevent recurrence should be considered as an essential component of management in some cases. Also, hyperbaric oxygen therapy, electrical stimulation, negative pressure wound therapy, bio-engineered skin and growth factors could be used as adjunct therapies for rapid healing of DFU. So, it's suggested that with appropriate patient education encourages them to regular foot care in order to prevent DFU and its complications. | Leila Yazdanpanah Morteza Nasiri Sara Adarvishi | 2015 | World Journal of Diabetes2015,6,1: | 55 |
| 3 | Neuroendocrine tumors of the gastro-entero-pancreatic system显示文摘Gastro-entero-pancreatic (GEP) neuroendocrine tumors (NETs) are rare neoplasms, although their prevalence has increased substantially over the past three decades. Moreover, there has been an increased clinical recognition and characterization of these neoplasms. They show extremely variable biological behavior and clinical course. Most NETs have endocrine function and secrete peptides and neuroamines that cause distinct clinical syndromes, including carcinoid syndrome; however, many are clinically silent until late presentation with mass effects. Investigation and management should be individualized for each patient, taking into account the likely natural history of the tumor and general health of the patient. Management strategies include surgery for cure or palliation, and a variety of other cytoreductive techniques, and medical treatment including chemotherapy, and biotherapy to control symptoms due to hormone release and tumor growth, with somatostatin analogues (SSAs) and alphainterferon. New biological agents and somatostatintagged radionuclides are under investigation. Advances in the therapy and development of centers of excellence which coordinate multicenter studies, are needed to improve diagnosis, treatment and therefore survival of patients with GEP NETs. | Sara Massironi Valentina Sciola Maddalena Peracchi Clorinda Ciafardini Matilde Pia Spampatti Dario Conte | 2008 | World Journal of Gastroenterology2008,14,35: | 44 |
| 4 | Acute-on-chronic liver failure:Pathogenesis,prognostic factors and management显示文摘Acute-on-chronic liver failure(ACLF) is increasingly recognized as a complex syndrome that is reversiblein many cases. It is characterized by an acute deterioration of liver function in the background of a pre-existing chronic liver disease often associated with a high short-term mortality rate. Organ failure(OF) is always associated, and plays a key role in determining the course, and the outcome of the disease. The definition of ACLF remains controversial due to its overall ambiguity, with several disparate criteria among various associations dedicated to the study of liver diseases. Although the precise pathogenesis needs to be clarified, it appears that an altered host response to injury might be a contributing factor caused by immune dysfunction, ultimately leading to a pro-inflammatory status, and eventually to OF. The PIRO concept(Predisposition, Insult, Response and Organ Failure) has been proposed to better approach the underlying mechanisms. It is accepted that ACLF is a different and specific form of liver failure, where a precipitating event is always involved, even though it cannot always be ascertained. According to several studies, infections and active alcoholism often trigger ACLF. Viral hepatitis, gastrointestinal haemorrhage, or drug induced liver injury, which can also provoke the syndrome. This review mainly focuses on the physiopathology and prognostic aspects. We believe these features are essential to further understanding and providing the rationale for improveddisease management strategies. | Sara Blasco-Algora José Masegosa-Ataz María Luisa Gutiérrez-García Sonia Alonso-López Conrado M Fernández-Rodríguez | 2015 | World Journal of Gastroenterology2015,21,42: | 45 |
| 5 | Proton pump inhibitor resistance, the real challenge in gastro-esophageal reflux disease显示文摘Gastro-esophageal reflux disease(GERD)is one of the most prevalent chronic diseases.Although proton pump inhibitors(PPIs)represent the mainstay of treatment both for healing erosive esophagitis and for symptom relief,several studies have shown that up to 40%of GERD patients reported either partial or complete lack of response of their symptoms to a standard PPI dose once daily.Several mechanisms have been proposed as involved in PPIs resistance,including ineffective control of gastric acid secretion,esophageal hypersensitivity,ultrastructural and functional changes in the esophageal epithelium.The diagnostic evaluation of a refractory GERD patients should include an accurate clinical evaluation,upper endoscopy,esophageal manometry and ambulatory pH-impedance monitoring,which allows to discriminate non-erosive reflux disease patients from those presenting esophageal hypersensitivity or functional heartburn.Treatment has been primarily based on doubling the PPI dose or switching to another PPI.Patients with proven disease,not responding to PPI twice daily,are eligible for anti-reflux surgery. | Michele Cicala Sara Emerenziani Michele Pier Luca Guarino Mentore Ribolsi | 2013 | World Journal of Gastroenterology2013,19,39: | 38 |
| 6 | MicroRNAs as a potential prognostic factor in gastric cancer显示文摘AIM:To compare the microRNA (miR) profiles in the primary tumor of patients with recurrent and non-recurrent gastric cancer.METHODS:The study group included 45 patients who underwent curative gastrectomies from 1995 to 2005 without adjuvant or neoadjuvant therapy and for whom adequate tumor content was available.Total RNA was extracted from formalin-fixed paraffin-embedded tumor samples,preserving the small RNA fraction.Initial profiling using miR microarrays was performed to identify potential biomarkers of recurrence after resection.The expression of the differential miRs was later verified by quantitative real-time polymerase chain reaction (qRT-PCR).Findings were compared between patients who had a recurrence within 36 mo of surgery (bad-prognosis group,n=14,31%) and those who did not (good-prognosis group,n=31,69%).RESULTS:Three miRs,miR-451,miR-199a-3p and miR-195 were found to be differentially expressed in tumors from patients with good prognosis vs patients with bad prognosis (P<0.0002,0.0027 and 0.0046 respectively).High expression of each miR was associated with poorer prognosis for both recurrence and survival.Using miR-451,the positive predictive value for non-recurrence was 100% (13/13).The expression of the differential miRs was verified by qRT-PCR,showing high correlation to the microarray data and similar separation into prognosis groups.CONCLUSION:This study identified three miRs,miR-451,miR-199a-3p and miR-195 to be predictive of recurrence of gastric cancer.Of these,miR-451 had the strongest prognostic impact. | Baruch Brenner Moshe B Hoshen Ofer Purim Miriam Ben David Karin Ashkenazi Gideon Marshak Yulia Kundel Ronen Brenner Sara Morgenstern Marisa Halpern Nitzan Rosenfeld Ayelet Chajut Yaron Niv Michal Kushnir | 2011 | World Journal of Gastroenterology2011,17,35: | 31 |

| 8 | Hepatocellular carcinoma in Asia: Prevention strategy and planning显示文摘AIM: To review all of epidemiological and etiological aspects of hepatocellular carcinoma(HCC) and examined the prevention of this disease in Asia.METHODS: We conducted a systematic review according to the PRISMA guidelines. We were chosen articles that published previously, from Pub Med(MEDLINE), the Cochrane database and Scopus. The key words used in this research were as follows: HCC in Asia and the way of prevention of this disease, with no language limitations. We selected those papers published before 2014 that we considered to be most important and appropriate. All relevant articles were accessed in full text and all relevant materials was evaluated and reviewed.RESULTS: More than 70% of all new cases of liver cancer were diagnosed in Asia, a region that 75% of all those chronically infected with hepatitis B virus(HBV) in the world. Chronic HBV infection is the main cause of HCC in Asia, where the virus is endemic and vertical transmission is common. Japan, Saudi Arabia, Egypt and Pakistan are exception because of high prevalence of HCV infection in these regions. The prevalence of this cancer is high in Eastern and South-Eastern Asia, But Middle Eastern countries are characterized as moderate prevalence rate of HCC region and Central Asia and some part of Middle Eastern countries are known as low prevalence rate of HCC. In addition of HBV and HCV the other factors such as aflatoxin, alcohol, obesity, diabetes and non-alcoholic fatty liver disease(NAFLD) might be responsible for a low prevalence of HCC in Asian countries. Currently available HCC therapies, chemotherapy, surgical are inefficient, mainly due to usually late diagnosis and high recurrence rates after surgical resection, and usually end with treatment failure. Liver transplantation also remains as a difficult strategy in patients with HCC. Thus prevention of HCC by treating and prevention HBV and HCV infection, the major causative agents of HCC, and the other riskfactors such as aflatoxin, alcohol, obesity, diabetes and NAFLD is of a great medical importance. CONCLUSION: The main challenge which still present in Asia, is the high prevalence of chronic hepatitis.So, prevention of HBV and HCV is the key strategy to reduce the incidence of HCC in Asia. | Sara Ashtari Mohamad Amin Pourhoseingholi Afsaneh Sharifian Mohamad Reza Zali | 2015 | World Journal of Hepatology2015,7,12: | 25 |

| 11 | 中国农村改革、土地管理变化与农牧民认识的转变——以内蒙古为例显示文摘国际科学研究团体普遍关心干旱区居民对土地退化的认识与态度的转变。本文就20世纪80年代实行经济改革以来中国北方农牧交错带土地管理的变化与农牧民认识的转变,以及随后发生的土地所有权的变化进行了探讨。研究区景观以有零星农田分布的沙丘地和以天然植被为主的大青沟自然保护区为主。根据农牧民的叙述,尽管由于降水量的变化导致作物产量的不稳定,但是,作物产量在总体上呈现增加趋势。产量增加的主要原因是玉米品种的更新和化肥施用量的增加。农牧民们普遍承认1997年以来'30年不变的土地政策'有利于他们在土地管理中进行长远的规划与投资。同时,他们也强调化肥使用对获得短期经济效益的重要作用。农牧民们也指出放牧与开垦对治理土壤侵蚀有不良的影响。大青沟自然保护区植被组成与周围植被组成的差异是人为影响的结果。 | Sara Brogaard 赵学勇 | 2002 | AMBIO-人类环境杂志2002,31,3: | 20 |
| 12 | Genome and transcriptome analysis of the grapevine(Vitis vinifera L.) WRKY gene family显示文摘The plant WRKY gene family represents an ancient and complex class of zinc-finger transcription factors(TFs)that are involved in the regulation of various physiological processes,such as development and senescence,and in plant response to many biotic and abiotic stresses.Despite the growing number of studies on the genomic organisation of WRKY gene family in different species,little information is available about this family in grapevine(Vitis vinifera L.).In the present study,a total number of 59 putative grapevine WRKY transcription factors(VvWRKYs)were identified based on the analysis of various genomic and proteomic grapevine databases.According to their structural and phylogentic features,the identified grapevine WRKY transcription factors were classified into three main groups.In order to shed light into their regulatory roles in growth and development as well as in response to biotic and abiotic stress in grapevine,the VvWRKYs expression profiles were examined in publicly available microarray data.Bioinformatics analysis of these data revealed distinct temporal and spatial expression patterns of VvWRKYs in various tissues,organs and developmental stages,as well as in response to biotic and abiotic stresses.To also extend our analysis to situations not covered by the arrays and to validate our results,the expression profiles of selected VvWRKYs in response to drought stress,Erysiphe necator(powdery mildew)infection,and hormone treatments(salicilic acid and ethylene),were investigated by quantitative real-time reverse transcription PCR(qRT-PCR).The present study provides a foundation for further comparative genomics and functional studies of this important class of transcriptional regulators in grapevine. | Min Wang Alessandro Vannozzi Gang Wang Ying-Hai Liang Giovanni Battista Tornielli Sara Zenoni Erika Cavallini Mario Pezzotti Zong-Ming(Max)Cheng | 2014 | Horticulture Research2014,1,1: | 19 |
| 13 | Mushroom Poisoning Outbreaks—China,2010–2020显示文摘ABSTRACT Introduction:Mushroom poisoning was the leading cause of foodborne disease outbreaks and outbreak-associated deaths in China.Mushroom poisoning outbreak surveillance can provide insight into the epidemiological characteristics of mushroom poisonings and guide policymaking and health education to reduce illnesses and deaths.Methods:Foodborne Disease Outbreak Surveillance System was upgraded in 2011 to collect foodborne disease outbreaks in China.Mushroom poisoning outbreaks during 2010–2020 were selected to analyze geographical distribution,seasonal distribution,and setting of food preparation.Results:A total of 10,036 outbreaks,which resulted in 38,676 illnesses and 788 deaths,were reported in this period.Mushroom poisonings occurred all over the country,but with highest incidence in the southwest and central China. | Weiwei Li Sara M.Pires Zhitao Liu Jinjun Liang Yafang Wang Wen Chen Chengwei Liu Jikai Liu Haihong Han Ping Fu Yunchang Guo | 2021 | China CDC weekly2021,3,24: | 18 |
| 14 | A randomized double-blind trial on perioperative administration of probiotics in colorectal cancer patients显示文摘AIM:To investigate whether probiotic bacteria,given perioperatively,might adhere to the colonic mucosa, reduce concentration of pathogens in stools,and modulate the local immune function. METHODS:A randomized,double-blind clinical trial was carried out in 31 subjects undergoing elective colorectal resection for cancer.Patients were allocated to receive either a placebo(group A,n=10),or a dose of 10 7 of a mixture of Bifidobacterium longum(BB536) and Lactobacillus johnsonii(La1)(group B,n=11),or the same mixture at a concentration of 10 9 (group C,n=10).Probiotics,or a placebo,were given orally 2 doses/d for 3 d before operation.The same treatment continued postoperatively from day two to day four. Stools were collected before treatment,during surgery (day 0)and 5 d after operation.During the operation, colonic mucosa samples were harvested to evaluate bacterial adherence and to assess the phenotype of dendritic cells(DCs)and lymphocyte subsets by surface antigen expression(flow cytometry).The presence of BB536 and La1 was evaluated by the random amplified polymorphism DNA method with specific polymerase chain reaction probes. RESULTS:The three groups were balanced for baseline and surgical parameters.BB536 was never found at any time-points studied.At day 0,La1 was present in 6/10(60%)patients in either stools or by biopsy in group C,in 3/11(27.2%)in group B,and none in the placebo group(P=0.02,C vs A).There was a linear correlation between dose given and number of adher- ent La1(P=0.01).The rate of mucosal colonization by enterobacteriacae was 30%(3/10)in C,81.8%(9/11) in B and 70%(7/10)in A(P=0.03,C vs B).The Enterobacteriacae count in stools was 2.4(log10 scale) in C,4.6 in B,and 4.5 in A(P=0.07,C vs A and B). The same trend was observed for colonizing enterococ- ci.La1 was not found at day+5.We observed greater expression of CD3,CD4,CD8,and naive and memory lymphocyte subsets in group C than in group A with a dose response trend(C>B>A).Treatment didnot affect DC phenotype or activation,but after ex vivo stimulation with lipopolysaccharides,groups C and B had a lower proliferation rate compared to group A (P=0.04).Moreover,dendritic phenotypes CD83-123, CD83-HLADR,and CD83-11c(markers of activation) were significantly less expressed in patients colonized with La1(P=0.03 vs not colonized). CONCLUSION:La1,but not BB536,adheres to the colonic mucosa,and affects intestinal microbiota byreducing the concentration of pathogens and modulates local immunity. | Luca Gianotti Lorenzo Morelli Francesca Galbiati Simona Rocchetti Sara Coppola Aldo Beneduce Cristina Gilardini Daniela Zonenschain Angelo Nespoli Marco Braga | 2010 | World Journal of Gastroenterology2010,16,2: | 18 |
| 15 | Helicobacter pylori infection and extragastric disorders in children: A critical update显示文摘Helicobacter pylori(H. pylori) is a highly prevalent, serious and chronic infection that has been associated causally with a diverse spectrum of extragastric disorders including iron deficiency anemia, chronic idiopathic thrombocytopenic purpura, growth retardation, and diabetes mellitus. The inverse relation of H. pylori prevalence and the increase in allergies, as reported from epidemiological studies, has stimulated research for elucidating potential underlying pathophysiological mechanisms. Although H. pylori is most frequently acquired during childhood in both developed and developing countries, clinicians are less familiar with the pediatric literature in the field. A better understanding of the H. pylori disease spectrum in childhood should lead to clearer recommendations about testing for and treating H. pylori infection in children who are more likely to develop clinical sequelae. A further clinical challenge is whether the progressive decrease of H. pylori in thelast decades, abetted by modern clinical practices, may have other health consequences. | Lucia Pacifico John F Osborn Valeria Tromba Sara Romaggioli Stefano Bascetta Claudio Chiesa | 2014 | World Journal of Gastroenterology2014,20,6: | 18 |
| 16 | Peroxisome proliferator activated receptors at the crossroad of obesity, diabetes, and pancreatic cancer显示文摘Pancreatic ductal adenocarcinoma(PDAC) is the fourth cause of cancer death with an overall survival of 5% at five years. The development of PDAC is characteristically associated to the accumulation of distinctive genetic mutations and is preceded by the exposure to several risk factors. Epidemiology has demonstrated that PDAC risk factors may be non-modifiable risks(sex, age, presence of genetic mutations, ethnicity) and modifiable and co-morbidity factors related to the specific habits and lifestyle. Recently it has become evident that obesity and diabetes are two important modifiable risk factors for PDAC. Obesity and diabetes are complex systemic and intertwined diseases and, over the years, experimental evidence indicate that insulin-resistance, alteration of adipokines, especially leptin and adiponectin, oxidative stress and inflammation may play a role in PDAC. Peroxisome proliferator activated receptor-γ(PPARγ) is a nuclear receptor transcription factor that is implicated in the regulation of metabolism, differentiation and inflammation. PPARγ is a key regulator of adipocytes differentiation, regulates insulin and adipokines production and secretion, may modulate inflammation, and it is implicated in PDAC. PPARγ agonists are used in the treatment of diabetes and oxidative stressassociated diseases and have been evaluated for the treatment of PDAC. PPARγ is at the cross-road of diabetes, obesity, and PDAC and it is an interesting target to pharmacologically prevent PDAC in obese and diabetic patients. | Simone Polvani Mirko Tarocchi Sara Tempesti Lapo Bencini Andrea Galli | 2016 | World Journal of Gastroenterology2016,22,8: | 17 |
| 17 | Gastroesophageal reflux disease: Update on inflammation and symptom perception显示文摘Although gastroesophageal reflux disease(GERD)is a common disorder in Western countries,with a significant impact on quality of life and healthcare costs,the mechanisms involved in the pathogenesis of symptoms remain to be fully elucidated.GERD symptoms and complications may result from a multifactorial mechanism,in which acid and acid-pepsin are the important noxious factors involved.Prolonged contact of the esophageal mucosa with the refluxed content,probably caused by a defective anti-reflux barrier and luminal clearance mechanisms,would appear to be responsible for macroscopically detectable injury to the esophageal squamous epithelium.Receptors on acid-sensitive nerve endings may play a role in nociception and esophageal sensitivity,as suggested in animal models of chronic acid exposure.Meanwhile,specific cytokine and chemokine profiles would appear to underlie the various esophageal phenotypes of GERD,explaining,in part,the genesis of esophagitis in a subset of patients.Despite these findings,which show a significant production of inflammatory mediators and neurotransmitters in the pathogenesis of GERD,the relationship between the hypersensitivity and esophageal inflammation is not clear.Moreover,the large majority of GERD patients(up to 70%)do not develop esophageal erosions,a variant of the condition called non-erosive reflux disease.This summary aims to explore the inflammatory pathway involved in GERD pathogenesis,to better understand the possible distinction between erosive and non-erosive reflux disease patients and to provide new therapeutic approaches. | Annamaria Altomare Michele Pier Luca Guarino Silvia Cocca Sara Emerenziani Michele Cicala | 2013 | World Journal of Gastroenterology2013,19,39: | 16 |
| 18 | Ursodeoxycholic acid therapy in gallbladder disease,a story not yet completed显示文摘Gallstone disease represents an important issue in the healthcare system.The principal non-invasive nonsurgical medical treatment for cholesterol gallstones is still represented by oral litholysis with bile acids.The first successful and documented dissolution of cholesterol gallstones was achieved in 1972.Since then a large number of investigators all over the world,have been dedicated in biochemical and clinical studies on ursodeoxycholic acid(UDCA),demonstrating its extreme versatility.This editorial is aimed to provide a brief review of recent developments in UDCA use,current indications for its use and,the more recent advances in understanding its effects in terms of an antiinflammatory drug. | Michele Pier Luca Guarino Silvia Cocca Annamaria Altomare Sara Emerenziani Michele Cicala | 2013 | World Journal of Gastroenterology2013,19,31: | 16 |
| 19 | Diagnostic strategy for occult hepatitis B virus infection显示文摘In 2008,the European Association for the study of the liver(EASL) defined occult hepatitis B virus infection (OBI) as the'presence of hepatitis B virus(HBV) DNA in the liver(with detectable or undetectable HBV DNA in the serum) of individuals testing hepatitis B surface antigen(HBsAg) negative by currently available assays'.Several aspects of occult HBV infection are still poorly understood,including the definition itself and a standardized approach for laboratory-based detection,which is the purpose of this review.The clinical significance of OBI has not yet been established;however,in terms of public health,the clinical importance arises from the risk of HBV transmission.Consequently,it is important to detect high-risk groups for occult HBV infection to prevent transmission.The main issue is,perhaps,to identify the target population for screening OBI.Viremia is very low or undetectable in occult HBV infection,even when the most sensitive methods are used,and the detection of the viral DNA reservoir in hepatocytes would provide the best evaluation of occult HBV prevalence in a defined set of patients.However,this diagnostic approach is obviously unsuitable:blood detection of occult hepatitis B requires assays of the highest sensitivity and specificity with a lower limit of detection<10 IU/mL for HBV DNA and<0.1 ng/mL for HBsAg. | Sara Ocana Maria Luisa Casas Ingrid Buhigas Jose Luis Lledo | 2011 | World Journal of Gastroenterology2011,17,12: | 16 |
| 20 | 精子DNA损伤的机制和临床应用显示文摘在男性配子各种不同的DNA异常中,DNA断裂最为常见,尤其是在不育症患者中。目前越来越多的研究表明,DNA断裂并不显著影响精子细胞的存活率、活动率、形态以及与卵细胞的结合能力。研究还证明,卵母细胞在一定程度上可以修复受损的DNA,其修复程度依赖于精子细胞DNA的损伤类型和卵母细胞的质量。因此,研究精子DNA断裂(SDF)在自然分娩或辅助生殖技术助孕中对胚胎发育、胚胎着床、妊娠结果、子代健康的影响变得非常重要。至今,针对SDF对生殖的影响的研究极少,且研究报道的结论很不一致。导致这种不一致的原因可能与检测SDF的手段不同、实验设计不同和精液标本选择标准不同有关。因此,目前还不能确定是否将SDF检测拽术砬用于受精评估和ART技术中。这表明,制定SDF检测技术的标准化方法势在必行,另外关于SDF对ART的影响有必要进行进一步的临床研究。 | Lara Tamburrino Sara Marchiani Margarita Montoya Francesco Elia Marino Ilaria Natali Marta Cambi Gianni Forti Elisabetta Baldi Monica Muratori | 2012 | Asian Journal of Andrology2012,14,1: | 16 |
