| 1 | Krüppel-like factors 4 and 5:the yin and yang regulators of cellular proliferation显示文摘Krüppel-like factors (KLFs) are evolutionarily conserved zinc finger-containing transcription factors with diverseregulatory functions in cell growth, proliferation, differentiation, and embryogenesis. KLF4 and KLF5 are two closelyrelated members of the KLF family that have a similar tissue distribution in embryos and adults. However, the two KLFsoften exhibit opposite effects on regulation of gene transcription, despite binding to similar, if not identical, cis-actingDNA sequences. In addition, KLF4 and 5 exert contrasting effects on cell proliferation in many instances; while KLF4is an inhibitor of cell growth, KLF5 stimulates proliferation. Here we review the biological properties and biochemicalmechanisms of action of the two KLFs in the context of growth regulation. | Amr M.GHALEB Mandayam O.NANDAN Sengthong CHANCHEVALAP W.Brian DALTON Irfan M.HISAMUDDIN Vincent W.YANG | 2005 | Cell Research2005,15,2: | 21 |

| 3 | Deep sedation during gastrointestinal endoscopy: Propofol-fentanyl and midazolam-fentanyl regimens显示文摘AIM: To compare deep sedation with propofol-fentanyl and midazolam-fentanyl regimens during upper gastrointestinal endoscopy. METHODS: After obtaining approval of the research ethics committee and informed consent, 200 patients were evaluated and referred for upper gastrointestinal endoscopy. Patients were randomized to receive propofol-fentanyl or midazolam-fentanyl (n = 100/group).We assessed the level of sedation using the observer's assessment of alertness/sedation (OAA/S) score and bispectral index (BIS). We evaluated patient and physician satisfaction, as well as the recovery time and complication rates. The statistical analysis was performed using SPSS statistical software and included the MannWhitney test, χ 2 test, measurement of analysis of variance, and the κ statistic. RESULTS: The times to induction of sedation, recovery, and discharge were shorter in the propofolfentanyl group than the midazolam-fentanyl group. According to the OAA/S score, deep sedation events occurred in 25% of the propofol-fentanyl group and 11% of the midazolam-fentanyl group (P = 0.014). Additionally, deep sedation events occurred in 19% of the propofol-fentanyl group and 7% of the midazolamfentanyl group according to the BIS scale (P = 0.039). There was good concordance between the OAA/S score and BIS for both groups (κ = 0.71 and κ = 0.63, respectively). Oxygen supplementation was required in 42% of the propofol-fentanyl group and 26% of the midazolam-fentanyl group (P = 0.025). The mean time to recovery was 28.82 and 44.13 min in the propofolfentanyl and midazolam-fentanyl groups, respectively (P < 0.001). There were no severe complications in either group. Although patients were equally satisfied with both drug combinations, physicians were more satisfied with the propofol-fentanyl combination. CONCLUSION: Deep sedation occurred with propofolfentanyl and midazolam-fentanyl, but was more frequent in the former. Recovery was faster in the propofol-fentanyl group. | Marcos Eduardo Lera dos Santos Fauze Maluf-Filho Dalton Marques Chaves Sergio Eiji Matuguma Edson Ide Gustavo de Oliveira Luz Thiago Ferreira de Souza Fernanda C Simoes Pessorrusso Eduardo Guimares Hourneaux de Moura Paulo Sakai | 2013 | World Journal of Gastroenterology2013,19,22: | 16 |
| 4 | Narrow-band imaging without magnification for detecting early esophageal squamous cell carcinoma显示文摘AIM:To compare narrow-band imaging(NBI)without image magnification,and chromoendoscopy with Lugol's solution for detecting high-grade dysplasia and intramu-cosal esophageal squamous cell carcinoma(SCC)in patients with head and neck cancer.METHODS:This was a prospective observational study of 129 patients with primary head and neck tumors consecutively referred to the Gastrointestinal Endoscopy Unit of Hospital das Clínicas,S?o Paulo University Medical School,Brazil,between August 2006 and Feb-ruary 2007.Conventional examinations with NBI and Lugol chromoendoscopy were consecutively performed,and the discovered lesions were mapped,recorded and sent for biopsy.The results of the three methods were compared regarding sensitivity,specificity,accuracy,positive predictive value,negative predictive value,positive likelihood value and negative likelihood value.RESULTS:Of the 129 patients,nine(7%)were diagnosed with SCC,5 of which were in situ and 4 which were intramucosal.All carcinomas were detected through NBI and Lugol chromoendoscopy.Only 4 lesions were diagnosed through conventional examination,all of which were larger than 10 mm.CONCLUSION:NBI technology with optical filters has high sensitivity and high negative predictive value for detecting superficial esophageal SCC,and produces results comparable to those obtained with 2.5%Lugol chromoendoscopy. | Edson Ide Fauze Maluf-Filho Dalton Marques Chaves Sergio Eiji Matuguma Paulo Sakai | 2011 | World Journal of Gastroenterology2011,17,39: | 15 |
| 5 | Video capsule endoscopy vs double-balloon enteroscopy in the diagnosis of small bowel bleeding:A systematic review and metaanalysis显示文摘AIM To compare the diagnostic accuracy of video capsule endoscopy(VCE) and double-balloon enteroscopy(DBE) in cases of obscure gastrointestinal bleeding(OGIB) of vascular origin.METHODS MEDLINE(via PubMed), LILACS(via BVS) and Cochrane/CENTRAL virtual databases were searched for studies dated before 2017. We identified prospective and retrospective studies, including observational, cohort, single-blinded and multicenter studies, comparing VCE and DBE for the diagnosis of OGIB, and data of all the vascular sources of bleeding were collected. All patients were subjected to the same gold standard method. Relevant data were then extracted from each included study using a standardized extraction form. We calculated study variables(sensitivity, specificity, prevalence, positive and negative predictive values and accuracy) and performed a meta-analysis using Meta-Disc software.RESULTS In the per-patient analysis, 17 studies(1477 lesions) were included. We identified3150 exams(1722 VCE and 1428 DBE) in 2043 patients and identified 2248 sources of bleeding, 1467 of which were from vascular lesions. Of these lesions, 864(58.5%) were diagnosed by VCE, and 613(41.5%) were diagnosed by DBE. The pretest probability for bleeding of vascular origin was 54.34%. The sensitivity of DBE was 84%(95%CI: 0.82-0.86; heterogeneity: 78.00%), and the specificity was92%(95%CI: 0.89-0.94; heterogeneity: 92.0%). For DBE, the positive likelihood ratio was 11.29(95%CI: 4.83-26.40; heterogeneity: 91.6%), and the negative likelihood ratio was 0.20(95%CI: 0.15-0.27; heterogeneity: 67.3%). Performing DBE after CE increased the diagnostic yield of vascular lesion by 7%, from 83% to90%.CONCLUSION The diagnostic accuracy of detecting small bowel bleeding from a vascular source is increased with the use of an isolated video capsule endoscope compared with isolated DBE. However, concomitant use increases the detection rate of the bleeding source. | Hélcio Pedrosa Brito Igor Braga Ribeiro Diogo Turiani Hourneaux de Moura Wanderley Marques Bernardo Dalton Marques Chaves Rogério Kuga Ethan Dwane Maahs Robson Kiyoshi Ishida Eduardo Turiani Hourneaux de Moura Eduardo Guimaraes Hourneaux de Moura | 2018 | World Journal of Gastrointestinal Endoscopy2018,10,12: | 10 |

| 8 | Hepatitis E virus in patients with acute severe liver injury显示文摘AIM: To examine the incidence of hepatitis E(HepE) in individuals with acute liver injury severe enough to warrant treatment at a transplant unit.METHODS: Hepatitis E virus(HEV) is an emerging pathogen in developed countries causing severe illness, particularly in immunocompromised patients or those with underlying chronic liver disease. HepE infection isoften under diagnosed, as clinicians can be reluctant to test patients who have not travelled to regions traditionally considered hyperendemic for HepE. There are few data regarding the significance of HEV in patients with very severe acute liver injury in developed countries. Eighty patients with acute severe liver injury attending the Scottish Liver Transplant unit were tested for HEV and anti-HEV IgG and IgM. Severe acute liver injury was defined as a sudden deterioration in liver function confirmed by abnormal liver function tests and coagulopathy or presence of hepatic encephalopathy. Eighty percent of these patients were diagnosed with paracetomol overdose. No patients had a history of chronic or decompensated chronic liver disease at time of sampling. IgG positive samples were quantified against the World Health Organization anti-HEV IgG standard. Samples were screened for HEV viral RNA by quantitative reverse transcription polymerase chain reaction.RESULTS: Four cases of hepatitis E were identified. Three of the four cases were only diagnosed on retrospective testing and were initially erroneously ascribed to drug-induced liver injury and decompensated chronic liver disease, with the cause of the decompensation uncertain. One case was caused by HEV genotype 1 in a traveller returning from Asia, the other three were autochthonous and diagnosed on retrospective testing. In two of these cases(where RNA was detected) HEV was found to be genotype 3, the most prevalent genotype in developed countries. Three patients survived, two of whom had been misdiagnosed as having drug induced liver injury. The fourth patient died from sepsis and liver failure precipitated as a result of hepatitis E infection and previously undiagnosed cirrhosis. Histopathology data to date is limited to mainly that seen for endemic HepE. All patients, with the exception of patient 1, demonstrated characteristics of HepE infection, as seen in previously described locally acquired cases.CONCLUSION: In patients with acute severe liver injury, HEV testing should be part of the initial diagnostic investigation algorithm irrespective of suspected initial diagnosis, age or travel history. | Claire Louise Crossan Kenneth J Simpson Darren G Craig Christopher Bellamy Janice Davidson Harry R Dalton Linda Scobie | 2014 | World Journal of Hepatology2014,6,6: | 4 |
| 9 | Femtojoule electro-optic modulation using a silicon– organic hybrid device显示文摘Energy-efficient electro-optic modulators are at the heart of short-reach optical interconnects,and silicon photonics is considered the leading technology for realizing such devices.However,the performance of all-silicon devices is limited by intrinsic material properties.In particular,the absence of linear electro-optic effects in silicon renders the integration of energy-efficient photonic–electronic interfaces challenging.Silicon–organic hybrid(SOH)integration can overcome these limitations by combining nanophotonic silicon waveguides with organic cladding materials,thereby offering the prospect of designing optical properties by molecular engineering.In this paper,we demonstrate an SOH Mach–Zehnder modulator with unprecedented efficiency:the 1-mm-long device consumes only 0.7 fJ bit^(-1) to generate a 12.5 Gbit s^(-1) data stream with a bit-error ratio below the threshold for hard-decision forward-error correction.This power consumption represents the lowest value demonstrated for a non-resonant Mach–Zehnder modulator in any material system.It is enabled by a novel class of organic electro-optic materials that are designed for high chromophore density and enhanced molecular orientation.The device features an electro-optic coefficient of r33<180 pm V^(-1) and can be operated at data rates of up to 40 Gbit s^(-1). | Sebastian Koeber Robert Palmer Matthias Lauermann Wolfgang Heni Delwin L Elder Dietmar Korn Markus Woessner Luca Alloatti Swen Koenig Philipp C Schindler Hui Yu Wim Bogaerts Larry R Dalton Wolfgang Freude Juerg Leuthold Christian Koos | 2015 | Light(Science & Applications)2015,4,1: | 4 |
| 10 | Cellulose-based materials in wastewater treatment of petroleum industry显示文摘The most abundant natural biopolymer on earth, cellulose fiber, may offer a highly efficient, low-cost, and chemical-free option for wastewater treatment. Cellulose is widely distributed in plants and several marine animals. It is a carbohydrate polymer consisting of β-1,4-linked anhydro-D-glucose units with three hydroxyl groups per anhydroglucose unit(AGU). Cellulose-based materials have been used in food, industrial, pharmaceutical, paper, textile production, and in wastewater treatment applications due to their low cost, renewability,biodegradability, and non-toxicity. For water treatment in the oil and gas industry, cellulose-based materials can be used as adsorbents, flocculants, and oil/water separation membranes. In this review, the uses of cellulose-based materials for wastewater treatment in the oil & gas industry are summarized, and recent research progress in the following aspects are highlighted: crude oil spill cleaning, flocculation of solid suspended matter in drilling or oil recovery in the upstream oil industry, adsorption of heavy metal or chemicals, and separation of oil/water by cellulosic membrane in the downstream water treatment. | Baoliang Peng Zhaoling Yao Xiaocong Wang Mitchel Crombeen Dalton GSweeney Kam Chiu Tam | 2020 | Green Energy & Environment2020,5,1: | 4 |
| 11 | High school sports programs differentially impact participation by sex显示文摘背景:研究表明,参加体育活动可降低儿童和青少年肥胖的风险。学校是促进儿童和青少年参加体育活动的理想环境,但目前尚不清楚体育活动的'获得'和'选择'如何影响学生的参与度,也不清楚学校体育课的特点对学生参与体育的影响是否存在性别差异。本研究旨在评价高中体育运动项目的特点,并确定这些体育课程对男女生参与运动队的影响程度。方法:用电话采访的方式纵向调查了1,244名新罕布什尔州和佛蒙特州的学生。学生自述他们小学至高中阶段参与运动队的情况。通过调查高中职员了解体育机会。在本研究中,'体育机会'是指每100名学生所对应的学校提供的体育项目种类《选择)和学校提供的体育种类中不限制参加人数的体育项目的比例(获得)。结果:约70%的儿童参加了至少一个体育运动队,男生为73%,女生为66%。研究发现在性别和两个体育机会变量之间存在显著交互影响。控制小学生参与体育活动和其他协变量后,发现如果学校不限制最受欢迎的体育项目的参与人数,男生会参加更多的体育运动队(RR=1.12,p<0.01)。相反,如果学校提供广泛的体育项目,女生会参加更多的体育运动队(RR=1 47,p<0.001)。结论:前人研究表明,参加体育活动能带来许多健康效益。对公共卫生工作包括预防肥胖而言,学校体育课可能是一个重要而有效但未被充分利用的对象。要使青少年参加更多的体育活动,就应综合考虑学校体育项目的获得和选择。学校可运用不同策略,促使男生和女生更多地参加体育活动。 | Keith M.

| 12 | 选择性雄激素受体调节剂治疗迟发性男性性腺功能低下症显示文摘几种睾酮制剂用于治疗老年男性性腺功能减退。这些疗法在其便利性、灵活性、区域供应和费用等方面有区别,但有共同的药代动力学基础,同时缺乏长期安全性数据。简洁和成本较低的基于药代动力学的注册临床试验使得开发改善性的治疗迟发性性腺功能减退的新疗法的商业动机减少了。在前列腺、头发、皮肤受雄激素缺乏影响的患者中,选择性雄激素受体调节剂已被证明可以提供合成代谢的好处。(目前,选择性雄激素受体调节剂的临床进展集中在有限定身体功能的临床终点的急性肌肉萎缩和低体重)。在具有有益的药理、理想的药代动力学的选择性雄激素受体调节剂应用于治疗迟发性男性性腺功能低下症前,其在男性性腺功能低下治疗中关于临床缺陷的更清晰的监管是必须的。 | Christopher C Coss Amanda Jones Michael L Hancock Mitchell S Steiner James T Dalton | 2014 | Asian Journal of Andrology2014,16,2: | 3 |
| 13 | Treatment of high-grade dysplasia and intramucosal carcinoma using radiofrequency ablation or endoscopic mucosal resection + radiofrequency ablation: Meta-analysis and systematic review显示文摘BACKGROUND The progression of Barrett's esophagus(BE) to early esophageal carcinoma occurs sequentially; the metaplastic epithelium develops from a low-grade dysplasia to a high-grade dysplasia(HGD), resulting in early esophageal carcinoma and,eventually, invasive carcinoma. Endoscopic approaches including resection and ablation can be used in the treatment of this condition.AIM To compare the effectiveness of radiofrequency ablation(RFA) vs endoscopic mucosal resection(EMR) + RFA in the endoscopic treatment of HGD and intramucosal carcinoma.METHODS In accordance with PRISMA guidelines, this systematic review included studies comparing the two endoscopic techniques(EMR + RFA and RFA alone) in the treatment of HGD and intramucosal carcinoma in patients with BE. Our analysis included studies involving adult patients of any age with BE with HGD or intramucosal carcinoma. The studies compared RFA and EMR + RFA methods were included regardless of randomization status.RESULTS The seven studies included in this review represent a total of 1950 patients, with742 in the EMR + RFA group and 1208 in the RFA alone group. The use of EMR +RFA was significantly more effective in the treatment of HGD [RD 0.35(0.15,0.56)] than was the use of RFA alone. The evaluated complications(stenosis,bleeding, and thoracic pain) were not significantly different between the two groups.CONCLUSION Endoscopic resection in combination with RFA is a safe and effective method in the treatment of HGD and intramucosal carcinoma, with higher rates of remission and no significant differences in complication rates when compared to the use of RFA alone. | Mileine Valente de Matos Alberto Machado da Ponte-Neto Diogo Turiani Hourneaux de Moura Ethan Dwane Maahs Dalton Marques Chaves Elisa Ryoka Baba Edson Ide Rubens Sallum Wanderley Marques Bernardo Eduardo Guimar?es Hourneaux de Moura | 2019 | World Journal of Gastrointestinal Endoscopy2019,11,3: | 2 |
