| 3 | Harnessing the RNA interference pathway to advance treatment and prevention of hepatocellular carcinoma显示文摘Primary liver cancer is the fifth most common malignan- cy in the world and is a leading cause of cancer-related mortality.Available treatment for hepatocellular carcino- ma(HCC),the commonest primary liver cancer,is rarely curative and there is a need to develop therapy that is more effective.Specific and powerful gene silencing that can be achieved by activating RNA interference(RNAi) has generated enthusiasm for exploiting this pathway for HCC therapy.Many studies have been carried out with the aim of silencing HCC-related cellular oncogenes or the hepatocarcinogenic hepatitis B virus(HBV)and hepatitis C virus(HCV).Proof of principle studies have demonstrated promising results,and an early clinical trial assessing RNAi-based HBV therapy is currently in progress.Although the data augur well,there are several significant hurdles that need to be overcome before the goal of RNAi-based therapy for HCC is realized.Particu- larly important are the efficient and safe delivery of RNAi effecters to target malignant tissue and the limitation of unintended harmful non-specific effects. | Patrick Arbuthnot Liam Jed Thompson | 2008 | World Journal of Gastroenterology2008,14,11: | 14 |

| 6 | Psychosocial factors and their association with reflux oesophagitis,Barrett's oesophagus and oesophageal adenocarcinoma显示文摘AIM:To investigate the role of psychological characteristics as risk factors for oesophageal adenocarcinoma(OAC),as well as the reflux-mediated precursor pathway.METHODS:An all-Ireland population-based case-control study recruited 230 reflux oesophagitis(RO),224 Barrett's oesophagus(BO) and 227 OAC patients and 260 controls.Each case/control group completed measures of stress,depression,self-efficacy,self-esteem,repression and social support.A comparative analysis was undertaken using polytomous logistic regression adjusted for potential confounders.RESULTS:Compared to controls,OAC patients were almost half as likely to report high stress levels over their lifetime(P = 0.010,OR 0.51;95%CI:0.29-0.90)and 36% less likely to report having experienced depression(OR 0.64;95%CI:0.42-0.98).RO patients reported significantly higher stress than controls particularly during middle-and senior-years(P for trends < 0.001).RO patients were 37% less likely to report having been highly emotionally repressed(OR 0.63;95%CI:0.41-0.95).All case groups(OAC,RO and BO) were more likely than controls to report having had substantial amounts of social support(OR 2.84;95%CI:1.63-4.97;OR 1.97;95%CI:1.13-3.44 and OR 1.83;95%CI:1.03-3.24,respectively).CONCLUSION:The improved psychological profile of OAC patients may be explained by response shift.The role of psychological factors in the development of OAC requires further investigation. | Paul Denver Michael Donnelly Liam J Murray Lesley A Anderson | 2013 | World Journal of Gastroenterology2013,19,11: | 5 |
| 7 | 人工湿地/微生物燃料电池技术的发展现状显示文摘人工湿地技术(CW)和微生物燃料电池(MFC)处理技术都是通过微生物的作用去除污水中的污染物。微生物燃料电池的阳极区为厌氧环境、阴极区则为好氧环境,而氧化还原条件和氧化还原电位梯度在人工湿地填料层中可自然形成。因此,近几年兴起对这两种污水处理技术相结合的研究,由此开发了人工湿地/微生物燃料电池技术(CW/MFC)。虽然国内外对于CW/MFC的研究才刚起步,资料有限,但CW/MFC的雏形已经形成。在综述国内外已有的CW/MFC文献资料的基础上,提出这一环境友好型污水处理和潜能利用技术今后的研究方向及面临的挑战。 | 王同悦 Liam Doherty 赵晓红 赵亚乾 胡沅胜 郝晓地 | 2015 | 中国给水排水2015,31,17: | 5 |
| 8 | 铝污泥人工湿地/微生物燃料电池工艺性能初步研究显示文摘水体污染和能源危机是当今人们亟待解决的两大难题,通过结合人工湿地及微生物燃料电池技术,开发出的人工湿地/微生物燃料电池耦合技术在同时解决这两大难题上具有巨大潜力。基于以铝污泥为填料的人工湿地/微生物燃料电池工艺,初步研究了其在不同运行机制下的污水处理效果和微生物燃料电池的产电性能。结果表明:上下同时进水方式与单纯上流式运行方式相比,电池的最大功率密度提升约60%(从0.168 W/m^3提高到0.268 W/m^3),对氨氮的去除率也有一定提高(从55%左右提高到75%左右),但对COD的去除率较上流式进水低(从84%左右降到64%左右);电极间距以及阴极的氧气供给对两种运行方式下电池性能的影响相当;通过多级运行的方式不仅可以提高出水水质,适当改变运行条件,电池的产电性能也可得到一定的提升。 | 赵晓红 徐磊 任柏铭 Liam Doherty 赵亚乾 | 2015 | 中国给水排水2015,31,17: | 5 |
| 9 | Risk factors for Barrett’s oesophagus and oesophageal adenocarcinoma:Results from the FINBAR study显示文摘AIM:To investigate risk factors associated with Barrett's oesophagus and oesophageal adenocarcinoma.METHODS:This all-Ireland population-based case-control study recruited 224 Barrett's oesophagus patients,227 oesophageal adenocarcinoma patients and 260 controls.All participants underwent a structured interview with information obtained about potential lifestyle and environmental risk factors.RESULTS:Gastro-oesophageal reflux was associated with Barrett's [OR 12.0(95% CI 7.64-18.7)] and oesophageal adenocarcinoma [OR 3.48(95% CI 2.25-5.41)].Oesophageal adenocarcinoma patients were more likely than controls to be ex-or current smokers [OR 1.72(95% CI 1.06-2.81)and OR 4.84(95% CI 2.72-8.61)respectively] and to have a high body mass index [OR 2.69(95% CI 1.62-4.46)].No significant associations were observed between these risk factors and Barrett's oesophagus.Fruit but not vegetables were negatively associated with oesophageal adenocarcinoma [OR 0.50(95% CI 0.30-0.86)].CONCLUSION:A high body mass index,a diet low in fruit and cigarette smoking may be involved in the progression from Barrett's oesophagus to oesophageal adenocarcinoma. | Lesley A Anderson RG Peter Watson Seamus J Murphy Brian T Johnston Harry Comber Jim Mc Guigan John V Reynolds Liam J Murray | 2007 | World Journal of Gastroenterology2007,13,10: | 5 |
| 10 | Dye-sensitized TiO2@SBA-15 composites: Preparation and their application in photocatalytic desulfurization显示文摘Photocatalytic oxidation desulfurization has become a research hotspot in recent years because of mild reaction conditions, less energy consumption and high selectivity. In this paper, TiO2 was loaded onto SBA-15 molecular sieves and sensitized with organic dyes(2, 9-dichloroquinacridone, DCQ) to extend its spectral response range from ultraviolet light to visible light. The catalyst DCQ-X%TiO2@SBA-15 was characterized by BET measurements, X-ray diffraction, Fourier transform infrared spectroscopy and Ultraviolet-visible diffuse reflection spectra, and then it was applied for photocatalytic oxidation desulfurization of gasoline. The effects of different catalytic systems, TiO2 concentration, catalyst dosage, and different model sulfur compounds on catalytic desulfurization performance were investigated. Experimental results show that DCQ-TiO2@SBA-15 has a better performance than the unsensitized TiO2@SBA-15, and the desulfurization rate can reach up to 96.1% in a reaction time of 90 min. | Guoqing Guo Haiyang Guo Feng Wang Liam John France Wanxin Yang Zhihong Mei Yinghao Yu | 2020 | Green Energy & Environment2020,5,1: | 4 |
| 11 | Have patients with esophagitis got an increased risk of adenocarcinoma? Results from a population-based study显示文摘AIM: To examine an increased risk of esophageal adenocarcinoma is restricted to patients who develop Barrett's esophagus or whether esophagitis per se is a risk factor for adenocarcinoma.METHODS: A population-based cohort of patients with histological evidence of esophagitis without Barrett's esophagus was constructed using electronic pathology reports relating to all esophageal biopsies in Northern Ireland between 1993 and 1996. Person-years of followup and incident cases of esophageal cancer were calculated by linking the cohort to death files and the Northern Ireland Cancer Registry records. Standardized incidence ratios (SIR) were calculated for esophageal cancers (adenocarcinoma, squamous cell carcinoma (SCC), and histologically unspecified cancers).RESULTS: A total of 2 013 patients in the cohort provided 13 559 patient-years of follow-up (mean follow-up 6.7 years). None of the patients developed adenocarcinoma. Three patients developed SCC, and six developed histologically unspecified cancers. The SIR for all esophageal cancers and for SCC were 2.73 (95%CI 1.25-5.19) and 2.93 (95%CI 0.61-8.59), respectively. In a sensitivity analysis in which all unspecified esophageal cancers were treated as adenocarcinomas, the SIR for adenocarcinoma was 2.64 (0.97-5.75).CONCLUSION: The risk of adenocarcinoma is not elevated in patients with histological evidence of esophagitis without Barrett's esophagus; however, these patients may have a moderately increased risk of SCC.Further studies are required to confirm these findings,which suggest that Barrett's esophagus, not esophagitis,is the key precursor lesion in the development of adenocarcinoma. | Seamus J Murphy Lesley A Anderson Brian T Johnston Deirdre A Fitzpatrick Peter RG Watson Pauline Monaghan Liam J Murray | 2005 | World Journal of Gastroenterology2005,11,46: | 4 |
| 12 | ABC efflux transporters at blood-central nervous system barriers and their implications for treating spinal cord disorders显示文摘The barriers present in the interfaces between the blood and the central nervous system form a major hurdle for the pharmacological treatment of central nervous system injuries and diseases.The family of ATP-binding cassette(ABC)transporters has been widely studied regarding efflux of medications at blood-central nervous system barriers.These efflux transporters include P-glycoprotein(abcb1),‘breast cancer resistance protein'(abcg2)and the various‘multidrug resistance-associated proteins'(abccs).Understanding which efflux transporters are present at the blood-spinal cord,blood-cerebrospinal fluid and cerebrospinal fluid-spinal cord barriers is necessary to determine their involvement in limiting drug transfer from blood to the spinal cord tissue.Recent developments in the blood-brain barrier field have shown that barrier systems are dynamic and the profile of barrier defenses can alter due to conditions such as age,disease and environmental challenge.This means that a true understanding of ABC efflux transporter expression and localization should not be one static value but instead a range that represents the complex patient subpopulations that exist.In the present review,the blood-central nervous system barrier literature is discussed with a focus on the impact of ABC efflux transporters on:(i)protecting the spinal cord from adverse effects of systemically directed drugs,and(ii)limiting centrally directed drugs from accessing their active sites within the spinal cord. | Liam M.

| 14 | Harnessing the HDAC–histone deacetylase enzymes,inhibitors and how these can be utilised in tissue engineering显示文摘There are large knowledge gaps regarding how to control stem cells growth and differentiation.The limitations of currently available technologies,such as growth factors and/or gene therapies has led to the search of alternatives.We explore here how a cell’s epigenome influences determination of cell type,and potential applications in tissue engineering.A prevalent epigenetic modification is the acetylation of DNA core histone proteins.Acetylation levels heavily influence gene transcription.Histone deacetylase (HDAC) enzymes can remove these acetyl groups,leading to the formation of a condensed and more transcriptionally silenced chromatin.Histone deacetylase inhibitors (HDACis) can inhibit these enzymes,resulting in the increased acetylation of histones,thereby affecting gene expression.There is strong evidence to suggest that HDACis can be utilised in stem cell therapies and tissue engineering,potentially providing novel tools to control stem cell fate.This review introduces the structure/function of HDAC enzymes and their links to different tissue types (specifically bone,cardiac,neural tissues),including the history,current status and future perspectives of using HDACis for stem cell research and tissue engineering,with particular attention paid to how different HDAC isoforms may be integral to this field. | Liam Lawlor Xuebin B.

| 15 | Heparin resistance in severe thermal injury:a prospective cohort study显示文摘Background:Low molecular-weight heparin(LMWH)is routinely administered to burn patients for thromboprophylaxis.Some studies have reported heparin resistance,yet the mechanism(s)and prevalence have not been systematically studied.We hypothesized that nucleosomes,composed of histone structures with associated DNA released from injured tissue and activated immune cells in the form of neutrophil extracellular traps(NETs or NETosis),neutralize LMWH resulting in suboptimal anticoagulation,assessed by reduction in anti-factor Xa activity.Methods:Blood was sampled from>15%total body surface area(TBSA)burn patients receiving LMWH on days 5,10 and 14.Peak anti-factor Xa(AFXa)activity,anti-thrombin(ATIII)activity,cellfree DNA(cfDNA)levels and nucleosome levels were measured.Mixed effects regression was adjusted for multiple confounders,including injury severity and ATIII activity,and was used to test the association between nucleosomes and AFXa.Results:A total of 30 patients with severe burns were included.Mean TBSA 43%(SD 17).Twentythree(77%)patients were affected by heparin resistance(defined by AFXa activity<0.2 IU/mL).Mean peak AFXa activity across samples was 0.18 IU/mL(SD 0.11).Mean ATIII was 81.9%activity(SD 20.4).Samples taken at higher LWMH doses were found to have significantly increased AFXa activity,though the effect was not observed at all doses,at 8000 IU no samples were heparin resistant.Nucleosome levels were negatively correlated with AFXa(r=−0.29,p=0.050)consistent with the hypothesis.The final model,with peak AFXa as the response variable,was adjusted for nucleosome levels(p=0.0453),ATIII activity(p=0.0053),LMWH dose pre-sample(p=0.0049),drug given(enoxaparin or tinzaparin)(p=0.03),and other confounders including severity of injury,age,gender,time point of sample.Conclusions:Heparin resistance is a prevalent issue in severe burns.Nucleosome levels were increased post-burn,and showed an inverse association with AFXa consistent with the hypothesis that they may interfere with the anticoagulant effect of heparin in vivo and contribute to heparin resistance.Accurate monitoring of AFXa activity with appropriate therapy escalation plans are recommended with dose adjustment following severe burn injury. | Liam D Cato Benjamin Bailiff Joshua Price Christos Ermogeneous Jon Hazeldine William Lester Gillian Lowe Christopher Wearn Jonathan RB Bishop Janet M Lord Naiem Moiemen Paul Harrison | 2021 | Burns & Trauma2021,9,1: | 3 |

| 18 | Wearable multifunctional printed graphene sensors显示文摘The outstanding properties of graphene have initiated myriads of research and development;yet, its economic impact is hamperedby the difficulties encountered in production and practical application. Recently discovered laser-induced graphene is generated bya simple printing process on flexible and lightweight polyimide films. Exploiting the electrical features and mechanical pliability ofLIG on polyimide, we developed wearable resistive bending sensors that pave the way for many cost-effective measurementsystems. The versatile sensors we describe can be utilized in a wide range of configurations, including measurement of force,deflection, and curvature. The deflection induced by different forces and speeds is effectively sensed through a resistancemeasurement, exploiting the piezoresistance of the printed graphene electrodes. The LIG sensors possess an outstanding range forstrain measurements reaching >10% A double-sided electrode concept was developed by printing the same electrodes on bothsides of the film and employing difference measurements. This provided a large bidirectional bending response combined withtemperature compensation. Versatility in geometry and a simple fabrication process enable the detection of a wide range of flowspeeds, forces, and deflections. The sensor response can be easily tuned by geometrical parameters of the bending sensors and theLIG electrodes. As a wearable device, LIG bending sensors were used for tracking body movements. For underwater operation,PDMS-coated LIG bending sensors were integrated with ultra-low power aquatic tags and utilized in underwater animal speedmonitoring applications, and a recording of the surface current velocity on a coral reef in the Red Sea. | Altynay Kaidarova Mohammed Asadullah Khan Marco Marengo Liam Swanepoel Alexander Przybysz Cobus Muller Andreas Fahlman Ulrich Buttner Nathan R.Geraldi Rory P.Wilson Carlos M.Duarte Jurgen Kosel | 2019 | npj Flexible Electronics2019,3,1: | 2 |
