1Cyclooxygenase-2 polymorphisms and the risk of esophageal adeno-or squamous cell carcinoma显示文摘AIM:To determine whether-1195 A→G and/or-765 G→C polymorphisms in Cyclooxygenase-2(COX-2 ) may have a risk modifying effect on the development of esophageal carcinoma in a Dutch Caucasian population.METHODS:Two study groups were recruited, 252 patients with esophageal carcinoma and 240 healthy controls, matched for race, age, gender and recruiting area.DNA was isolated from whole blood and used for genotyping.PCR products were digested with restriction enzymes and products were analyzed by agarose gel electrophoresis.Odds ratios(OR) and 95% confldence intervals(CI) were estimated.RESULTS:The distribution of the-1195 A→G polymorphism was signif icantly different in esophageal cancer patients compared to controls.The-1195 GG genotype resulted in a higher risk of developing esophageal adenocarcinoma(OR = 3.85, 95% CI:1.45-10.3) compared with the-1195 AA genotype as a reference.The-765 G→C genotype distribution was not different between the two groups.The GG/ GG haplotype was present more often in esophageal adenocarcinoma patients than in controls(OR = 3.45, 95% CI:1.24-9.58;with AG/AG as a reference).The same trends were observed in patients with squamous cell carcinomas, however, the results did not reach statistical signif icance.CONCLUSION:Presence of the COX-2-1195 GG genotype and of the GG/GG haplotype may result in a higher risk of developing esophageal carcinoma.Jón O Kristinsson Paul van Westerveld Rene HM te Morsche Hennie MJ Roelofs T Wobbes Ben JM Witteman Adriaan CITL Tan Martijn GH van Oijen Jan BMJ Jansen Wilbert HM Peters 2009World Journal of Gastroenterology2009,15,28:11
2英国胃肠病学会关于胃癌风险患者的诊断和管理指南显示文摘胃癌预后较差,部分原因在于诊断较晚。胃癌的危险因素包括幽门螺杆菌(H.pylori,HP)感染和胃癌家族史,尤其是遗传性弥漫性胃癌和恶性贫血。胃癌发展的阶段包括慢性胃炎、胃黏膜萎缩(GA)、胃黏膜肠化生(GIM)和异型增生。胃癌早期发现和提高生存率的关键是在内镜检查前以非侵入性方式识别高危人群。然而,尽管生物标志物可能有助于检测慢性萎缩性胃炎,但尚无足够的证据支持其用于人群筛查。高质量内镜检查是胃癌早期发现的重要组成部分,图像增强内镜结合组织病理学活检是GA和GIM最佳的诊断方法,并能准确进行风险分层。按照悉尼标准从胃窦、角切迹、小弯和大弯进行活检,既能明确诊断,也能对胃癌进行风险分层。理想状态应当是在高质量内镜检查中对GA或GIM区域活检。英国属于低危地区,可根据需要接受常规诊断性胃镜检查,但没有足够证据支持筛查,对于广泛GA或GIM的患者,每3年检查内镜。对于胃异型增生和早期癌,只要满足标准,内镜下黏膜切除术或内镜黏膜下剥离术的治疗有效,成功率高,复发率低。Matthew Banks David Graham Marnix Jansen TakujiGotoda Sergio Coda Massimiliano di Pietro NoriyaUedo Pradeep Bhandari D Mark Pritchard Ernst J Kuipers Manuel Rodriguez-Justo Marco R Novelli KrishRagunath Neil Shepherd Mario Dinis-Ribeiro 乌雅罕(译) 张冬雪(译) 牛占岳(校) 刘鑫(校) 丁士刚(译/校) 2020中华胃肠内镜电子杂志2020,7,2:10
3Plasmonics for solid-state lighting: enhanced excitation and directional emission of highly efficient light sources显示文摘Light sources based on reliable and energy-efficient light-emitting diodes (LEDs) are instrumental in the development of solid-statelighting (SSL). Most research efforts in SSL have focused on improving both the intrinsic quantum efficiency (QE) and the stability oflight emitters. For this reason, it is broadly accepted that with the advent of highly efficient (QE close to 1) and stable emitters, thefundamental research phase of SSL is coming to an end. In this study, we demonstrate a very large improvement in SSL emission (above70-fold directional enhancement for p-polarized emission and 60-fold enhancement for unpolarized emission) using nanophotonicstructures. This is attained by coupling emitters with very high QE to collective plasmonic resonances in periodic arrays of aluminumnanoantennas. Our results open a new path for fundamental and applied research in SSL in which plasmonic nanostructures are able tomold the spectral and angular distribution of the emission with unprecedented precision.Gabriel Lozano Davy J Louwers Said RK Rodrı´guez Shunsuke Murai Olaf TA Jansen Marc A Verschuuren Jaime Gomez Rivas 2013Light(Science & Applications)2013,2,1:8
4Role of E3 ubiquitin ligases in lung cancer显示文摘E3 ubiquitin ligases are a large family of proteins that catalyze the ubiquitination of many protein substrates for targeted degradation by the 26S proteasome.Therefore,E3 ubiquitin ligases play an essential role in a variety of biological processes including cell cycle regulation,proliferation and apoptosis.E3 ubiquitin ligases are often found overexpressed in human cancers,including lung cancer,and their deregulation has been shown to contribute to cancer development.However,the lack of specific inhibitors in clinical trials is a major issue in targeting E3 ubiquitin ligases with currently only one E3 ubiquitin ligase inhibitor being tested in the clinical setting.In this review,we focus on E3 ubiquitin ligases that have been found deregulated in lung cancer.Furthermore,we discuss the processes in which they are involved and evaluate them as potential anti-cancer targets.By better understanding the mechanisms by which E3 ubiquitin ligases regulate biological processes and their exact role in carcinogenesis,we can improve the development of specific E3 ubiquitin ligase inhibitors and pave the way for novel treatment strategies for cancer patients.Barbara C Snoek Leonie HAM de Wilt Gerrit Jansen Godefridus J Peters 2013World Journal of Clinical Oncology2013,4,3:5
5miR147b:白细胞介素-1β介导的人类星形胶质细胞炎症中的新型关键调节因子显示文摘星形胶质细胞是大脑炎症过程的重要介质,可能在包括癫痫在内的几种神经系统疾病中起重要作用。星形胶质细胞中可生产几种miRNA,是炎症通路的关键调节因子,还可能用作治疗靶标。本研究将探索在体外IL-1β介导的炎症条件下,星形胶质细胞内生成的miRNA及其功能,并在人癫痫脑组织中验证。我们通过测序评估IL-1β刺激的人胎儿星形胶质细胞培养物中的miRNA和mRNA表达。使用miRNA模拟物在细胞培养物中过表达miRNA。使用原位杂交技术检测患有结节性硬化症复合体或颞叶癫痫伴海马硬化患者的切除脑组织中miRNA的表达。我们发现了2种差异表达的miRNA:miR146a和miR147b,它们与免疫/炎症反应相关基因的表达增加有关。既往有研究报道,在星形胶质细胞和结节性硬化复合细胞培养物中使用IL-1β刺激后,miR147b的过表达降低了促炎介质IL-6和COX-2的表达。miR146a和miR147b过表达降低了星形胶质细胞的增殖并促进人神经干细胞的神经元分化。miR147b在致癫痫脑中的星形胶质细胞中表达增加。由于其抗炎和恢复异常星形细胞增殖和促进神经元分化的能力,miR146a和miR147b作为与炎症相关的神经疾病(例如癫痫)的潜在治疗靶标值得进一步研究。van Scheppingen J Mills JD Zimmer TS Broekaart DWM Iori V Bongaarts A Anink JJ Iyer AM Korotkov A Jansen FE van Hecke W Spliet WG van Rijen PC Baayen JC Vezzani A van Vliet EA Aronica E 聂昊 2018神经损伤与功能重建2018,13,12:3
6Chronic antiepileptic drug use and functional network efficiency: A functional magnetic resonance imaging study显示文摘AIM To increase our insight in the neuronal mechanisms underlying cognitive side-effects of antiepileptic drug(AED) treatment.METHODS The relation between functional magnetic resonance-acquired brain network measures, AED use, and cognitive function was investigated. Three groups of patients with epilepsy with a different risk profile for developing cognitive side effects were included: A 'low risk' category(lamotrigine or levetiracetam, n=16), an 'intermediate risk' category(carbamazepine, oxcarbazepine, phenytoin, or valproate, n=34) and a 'high risk' category(topiramate, n=5). Brain connectivity was assessed using resting state functional magnetic resonance imaging and graph theoretical network analysis. The Computerized Visual Searching Task was used to measure central information processing speed, a common cognitive side effect of AED treatment. RESULTS Central information processing speed was lower in patients taking AEDs from the intermediate and high risk categories, compared with patients from the low risk category. The effect of risk category on global efficiency was significant(P < 0.05, ANCOVA), with a significantly higher global efficiency for patient from the low category compared with the high risk category(P < 0.05, post-hoc test). Risk category had no significant effect on the clustering coefficient(ANCOVA, P > 0.2). Also no significant associations between information processing speed and global efficiency or the clustering coefficient(linear regression analysis, P > 0.15) were observed. CONCLUSION Only the four patients taking topiramate show aberrant network measures, suggesting that alterations in functional brain network organization may be only subtle and measureable in patients with more severe cognitive side effects.Tamar M van Veenendaal Dominique M IJff Albert P Aldenkamp Richard H C Lazeron Paul A M Hofman Anton J A de Louw Walter H Backes Jacobus F A Jansen 2017World Journal of Radiology2017,9,6:2
