1Ischemia/reperfusion injury and cardioprotective mechanisms:Role of mitochondria and reactive oxygen species显示文摘Reperfusion therapy must be applied as soon as possible to attenuate the ischemic insult of acute myocardial infarction(AMI).However reperfusion is responsible for additional myocardial damage,which likely involves opening of the mitochondrial permeability transition pore(mPTP).In reperfusion injury,mitochondrial damage is a determining factor in causing loss of cardiomyocyte function and viability.Major mechanisms of mitochondrial dysfunction include the long lasting opening of mPTPs and the oxidative stress resulting from formation of reactive oxygen species(ROS).Several signaling cardioprotective pathways are activated by stimuli such as preconditioning and postconditioning,obtained with brief intermittent ischemia or with pharmacological agents.These pathways converge on a common target,the mitochondria,to preserve their function after ischemia/reperfusion.The present review discusses the role of mitochondria in cardioprotection,especially the involvement of adenosine triphosphate-dependent potassium channels,ROS signaling,and the mPTP.Ischemic postconditioning has emerged as a new way to target the mitochondria,and to drastically reduce lethal reperfusion injury.Several clinical studies using ischemic postconditioning during angioplasty now support its protective effects,and an interesting alternative is pharmacological postconditioning.In fact ischemic postconditioning and the mPTP desensitizer,cyclosporine A,have been shown to induce comparable protection in AMI patients.Maria-Giulia Perrelli Pasquale Pagliaro Claudia Penna 2011World Journal of Cardiology2011,3,6:64
2作物地膜覆盖安全期概念和估算方法探讨显示文摘该研究首次提出作物地膜覆盖安全期的概念,将其定义为'某一作物在某一区域要求地膜覆盖的最佳天数,也就是地膜覆盖农田土面能保持膜面完整的日数',在此日数之前地膜应该保持基本完整,维持增温保墒和防除杂草等功能,此日数之后,这些功能基本消失。明确作物地膜覆盖安全期有利于作物生产的高效管理,指导地膜生产者研发出满足农业生产需求和成本较低的地膜产品,协助农民根据覆盖作物种类和生产条件选择合适的农用地膜。在此基础上,该研究构建了基于地膜覆盖增温保墒和抑灭杂草等功能测定和农作物郁闭度测定的2种作物地膜覆盖安全期估算方法。第1种方法是通过对作物覆盖地膜条件下土壤温度和水分的连续监测,构建作物地膜覆盖与未覆盖农田土壤温度、水分和杂草控制的时序图,寻求二者的交汇或者重合点即地膜覆盖的增温保墒功能消失或者基本消失的时间节点,从覆盖到这个日期的天数分别属于某种作物地膜覆盖的温度安全期和水分安全期。第2种方法式是通过系统监测作物全生育期郁闭度和地膜覆盖功能参数,建立作物郁闭度与地膜覆盖主要功能的关系曲线,综合研判后确定地膜覆盖功能消失时作物郁闭度,计算作物地膜覆盖安全期。作物地膜覆盖安全期相关研究可为构建中国地膜覆盖技术适应性评价体系、探明地膜覆盖适宜区域的空间分异规律、以及生物降解地膜生产和应用提供技术支撑。严昌荣 何文清 刘恩科 林涛 Pasquale Mormile 刘爽 刘勤 2015农业工程学报2015,31,9:58
3Modern management of anal fistula显示文摘Ideal surgical treatment for anal fistula should aim to eradicate sepsis and promote healing of the tract,whilst preserving the sphincters and the mechanism of continence.For the simple and most distal fistulae,conventional surgical options such as laying open of the fistula tract seem to be relatively safe and therefore,well accepted in clinical practise.However,for the more complex fistulae where a significant proportion of the anal sphincter is involved,great concern remains about damaging the sphincter and subsequent poor functional outcome,which is quite inevitable following conventional surgical treatment.For this reason,over the last twodecades,many sphincter-preserving procedures for the treatment of anal fistula have been introduced with the common goal of minimising the injury to the anal sphincters and preserving optimal function.Among them,the ligation of intersphincteric fistula tract procedure appears to be safe and effective and may be routinely considered for complex anal fistula.Another technique,the anal fistula plug,derived from porcine small intestinal submucosa,is safe but modestly effective in long-term follow-up,with success rates varying from 24%-88%.The failure rate may be due to its extrusion from the fistula tract.To obviate that,a new designed plug(GORE BioA ) was introduced,but long term data regarding its efficacy are scant.Fibrin glue showed poor and variable healing rate(14%-74%).Fi La C and video-assisted anal fistula treatment procedures,respectively using laser and electrode energy,are expensive and yet to be thoroughly assessed in clinical practise.Recently,a therapy using autologous adiposederived stem cells has been described.Their properties of regenerating tissues and suppressing inflammatory response must be better investigated on anal fistulae,and studies remain in progress.The aim of this present article is to review the pertinent literature,describing the advantages and limitations of new sphincterpreserving techniques.Elsa Limura Pasquale Giordano 2015World Journal of Gastroenterology2015,21,1:59
4Management of cholelithiasis with choledocholithiasis:Endoscopic and surgical approaches显示文摘Gallstone disease and complications from gallstones are a common clinical problem.The clinical presentation ranges between being asymptomatic and recurrent attacks of biliary pain requiring elective or emergency treatment.Bile duct stones are a frequent condition associated with cholelithiasis.Amidst the total cholecystectomies performed every year for cholelithiasis,the presence of bile duct stones is 5%-15%;another small percentage of these will develop common bile duct stones after intervention.To avoid serious complications that can occur in choledocholithiasis,these stones should be removed.Unfortunately,there is no consensus on the ideal management strategy to perform such.For a long time,a direct open surgical approach to the bile duct was the only unique approach.With the advent of advanced endoscopic,radiologic,and minimally invasive surgical techniques,however,therapeutic choices have increased in number,and the management of this pathological situation has become multidisciplinary.To date,there is agreement on preoperative management and the need to treat cholelithiasis with choledocholithiasis,but a debate still exists on how to cure the two diseases at the same time.In the era of laparoscopy and miniinvasiveness,we can say that therapeutic approaches can be performed in two sessions or in one session.Comparison of these two approaches showed equivalent success rates,postoperative morbidity,stone clearance,mortality,conversion to other procedures,total surgery time,and failure rate,but the onesession treatment is characterized by a shorter hospital stay,and more cost benefits.The aim of this review article is to provide the reader with a general summary of gallbladder stone disease in association with the presence of common bile duct stones by discussing their epidemiology,clinical and diagnostic aspects,and possible treatments and their advantages and limitations.Pasquale Cianci Enrico Restini 2021World Journal of Gastroenterology2021,27,28:46
5Surgical treatment of anal stenosis显示文摘Anal stenosis is a rare but serious complication of anorectal surgery, most commonly seen after hemorrhoidectomy. Anal stenosis represents a technical challenge in terms of surgical management. A Medline search of studies relevant to the management of anal stenosis was undertaken. The etiology, pathophysiology and classifi cation of anal stenosis were reviewed. An overview of surgical and non-surgical therapeutic options was developed. Ninety percent of anal stenosis is caused by overzealous hemorrhoidectomy. Treatment, both medical and surgical, should be modulated based on stenosis severity. Mild stenosis can be managed conservatively with stool softeners or fiber supplements. Sphincterotomy may be quite adequate for a patient with a mild degree of narrowing. For more severe stenosis, a formal anoplasty should be performed to treat the loss of anal canal tissue. Anal stenosis may be anatomic or functional. Anal stricture is most often a preventable complication. Many techniques have been used for the treatment of anal stenosis with variable healing rates. It is extremely diffi cult to interpret the results of the various anaplastic procedures de in the literature as prospective trials have not been performed. However, almost any approach will at least improve patient symptoms.Giuseppe Brisinda Serafino Vanella Federica Cadeddu Gaia Marniga Pasquale Mazzeo Francesco Brandara Giorgio Maria 2009World Journal of Gastroenterology2009,15,16:22
6二氢嘧啶脱氢酶、胸苷酸合成酶、c-myc和p53基因在小鼠肝组织中表达的昼夜节律性研究(英文)显示文摘背景与目的:5-Fluorouracil(5-FU)主要通过抑制胸苷酸合成酶发挥抗癌作用,而二氢嘧啶脱氢酶是5-FU体内代谢的一个起始酶和限速酶。在本研究中,我们对二氢嘧啶脱氢酶、胸苷酸合成酶、c-myc和p53基因在小鼠肝脏中表达的昼夜节律进行研究。方法:本实验共采用了24只雄性B6D2F1小鼠。所有实验动物在实验中进行了4周光照同步化(12h光照:12h黑暗)。体温和休息-活动节律通过腹腔埋置的微型感受器进行动态监测。动物分别在3,7,11,15,19,23HALO(灯亮后小时数)被处死并取出肝脏冻存。肝脏标本中抽提的总RNA用LightCycler-SYBRGreenITM扩增系统进行实时定量RT-PCR。结果:小鼠的体温和休息-活动均呈现明显和相似的昼夜节律,其峰值均位于黑暗期(相当于小鼠活动相),谷值则位于光照期(相当于小鼠休息相)。二氢嘧啶脱氢酶在mRNA水平呈现出明显的昼夜节律性,其峰值时间位于16HALO左右即位于小鼠活动相(P=0.0012)。胸苷酸合成酶在mRNA水平具有昼夜节律表达的趋势,其峰值时间出现在光照期(P=0.079)。C-myc和p53在mRNA水平的节律性表达在本实验中无统计学意义。结论:二氢嘧啶脱氢酶和胸苷酸合成酶在mRNA水平呈现出昼夜节律性,二者峰值时间相差约12h,这一结果提示可以利用二者在转录水平的时间差异用5-FU进行时间化疗。吴明玮 冼励坚 李晓梅 lnnominato Pasquale lvi Francis 2004癌症2004,23,3:22
7Mechanisms and clinical significance of early recurrences of atrial arrhythmias after catheter ablation for atrial fibrillation显示文摘Early recurrence of atrial arrhythmias(ERAA) after ablation is common and strongly predicts late recurrences and ablation failure. However, since arrhythmia may eventually resolve in up to half of patients with ERAA, guidelines do not recommend immediate reintervention for ERAA episodes occurring during a 3-mo postablation blanking period. Certain clinical demographic, electrophysiologic, procedural, and ERAA-related characteristics may predict a higher likelihood of longterm ablation failure. In this review, we aim to discuss potential mechanisms of ERAA, and to summarize the clinical significance, prognostic implications, and treatment options for ERAA.Jackson J Liang Sanjay Dixit Pasquale Santangeli 2016World Journal of Cardiology2016,8,11:18
8Contrast-enhanced ultrasound in differentiating malignant from benign portal vein thrombosis in hepatocellular carcinoma显示文摘Portal vein thrombosis(PVT) may occur in liver cirrhosis patients. Malignant PVT is a common complication in cirrhotic patients with concomitant hepatocellular carcinoma(HCC) and, in some cases, it may be even the initial sign of an undetected HCC. Detection of malignant PVT in a patient with liver cirrhosis heavily affects the therapeutic strategy. Gray-scale ultrasound(US) is widely unreliable for differentiating benign and malignant thrombi. Although effective for this differential diagnosis, fine-needle biopsy remains an invasive technique. Sensitivity of color-doppler US in detection of malignant thrombi is highly dependent on the size of the thrombus. Contrast-enhanced computed tomography(CT) and contrast-enhanced magnetic resonance(MRI) can be useful to assess the nature of portal thrombus, while limited data are currently available about the role of positron emission tomography(PET) and PET-CT. In contrast with CT, MRI, PET, and PET-CT, contrast-enhanced ultrasound(CEUS) is a fast, effective, well tolerated and cheap technique, that can be performed even in the same session in which the thrombus has been detected. CEUS can be performed bedside and can be available also in transplanted patients. Moreover, CT and MRI only yield a snapshot analysis during contrast diffusion, while CEUS allows for a continuous real-time imaging of the microcirculation that lasts several minutes, so that the whole arterial phase and the late parenchymal phase of the contrast diffusion can be analyzed continuously by real-time US scanning. Continuous real-time monitoring of contrast diffusion entails an easy detection of thrombus maximum enhancement. Moreover, continuous quantitative analyses of enhancement(wash in- wash out studies) by CEUS during contrast diffusion is nowadays available in most CEUS machines, thus giving a more sophisticated and accurate evaluation of the contrast distribution and an increased confidence in diagnosis in difficult cases. In conclusion, CEUS is avery reliable technique with a high intrinsic sensitivity for portal vein patency assessment. More expensive and sophisticated techniques(i.e., CT, MRI, PET, and PET-CT) should only be indicated in undetermined cases at CEUS.Luciano Tarantino Pasquale Ambrosino Matteo Nicola Dario Di Minno 2015World Journal of Gastroenterology2015,21,32:18
9Depression and chronic heart failure in the elderly: an intriguing relationship显示文摘长期的心失败和压抑的混乱有高流行和发生在老。几研究显示出消沉怎么趋于加重共存的长期的心失败和它的临床的结果并且反过来也如此,在特别老。在长期的心失败和消沉在之间的否定协同老可以被接近仅仅考虑位于两个这些条件下面的 multifaceted pathophysiological 特征,例如行为因素, neurohormonal 激活,煽动性的调停人, hypercoagulability 和脉管的损坏。不过,在这二个条件之间的 pathophysiological 连接还很好没被建立。尽管有在长期的心失败的消沉的高流行老病人和它的否定预示的价值,因为分享的症状,它特别经常是未被认出的。用可靠问询表,屏蔽心情混乱因此与长期的心失败在老病人被推荐,就算不能由心理健康职业运动员代替诊断会见。在这个背景,消沉的治疗要求包括的一条多学科的途径:心理疗法,抗抑郁剂,锻练训练和 electroconvulsive 治疗。尽管有冲突结果,有选择血清素举起禁止者的药理学治疗改进生活的质量但是不保证更好的结果。锻练训练在改进生活和预后的质量是有效的,但是同时心脏的康复服务是极大地 underutilized。Ilaria Liguori Gennaro Russo Francesco Curcio Giuseppe Sasso David Della-Morte Gaetano Gargiulo Flora Pirozzi Francesco Cacciatore Domenico Bonaduce Pasquale Abete Gianluca Testa 2018Journal of Geriatric Cardiology2018,15,6:16
10Nerve growth factor involvement in liver cirrhosis and hepatocellular carcinoma显示文摘AIM: To define NGF (nerve growth factor) and its high- affinity receptor trkANGF presence and distribution in fibrotic liver and in HCC, and to verify if NGF might have a role in fibrosis and HCC. METHODS: Intracellular distribution of NGF and trkANGF were assessed by immunohistochemistry and immuno- electron microscopy in liver specimens from HCC, cirrhosis or both. ELISA was used to measure circulating NGF levels. RESULTS: NGF and trkANGF were highly expressed in HCC tissue, mainly localized in hepatocytes, endothelial and some Kupffer cells. In the cirrhotic part of the liver they were also markedly expressed in bile ducts epithelial and spindle-shaped cells. Surprisingly, in cirrhotic tissue from patients without HCC, both NGF and trkANGF were negative. NGF serum levels in cirrhotic and/or HCC patient were up to 25-fold higher than in controls. CONCLUSION: NGF was only detected in liver tissue with HCC present. Intracellular distribution suggests paracrine and autocrine mechanisms of action. Better definition of mechanisms may allow for therapeutic and diagnostic/prognostic use of NGF.Guido Rasi Annalucia Serafino Lia Bellis Maria Teresa Lonardo Federica Andreola Manuela Zonfrillo Giovanni Vennarecci Pasquale Pierimarchi Paola Sinibaldi Vallebona Giuseppe Maria Ettorre Eugenio Santoro Claudio Puoti 2007World Journal of Gastroenterology2007,13,37:13
11Current concepts and future strategies in the antimicrobial therapy of emerging Gram-positive spontaneous bacterial peritonitis显示文摘Spontaneous bacterial peritonitis(SBP) is the most common infection in end-stage liver disease patients.SBP is defined as an ascitic fluid infection with a polymorphonuclear leucocyte count ≥ 250/mm^3 without an evident intra-abdominal surgically treatable source.Several mechanisms contribute to SBP occurrence,including translocation of gut bacteria and their products,reduced intestinal motility provoking bacterial overgrowth,alteration of the gut's barrier function and local immune responses.Historically,Gram-negative enteric bacteria have been the main causative agents of SBP,thereby guiding the empirical therapeutic choice.However,over the last decade,a worryingly increasing prevalence of Gram-positive and multi-drug resistant(MDR) SBP has been seen.Recently,the microbiological spectrum of SBP seems to have changed in Europe due to a high prevalence of Gram-positive bacteria(48%-62%).The overall proportion of MDR bacteria is up to 22%-73% of cases.Consequently,empirical therapy based on thirdgeneration cephalosporins or amoxicillin/clavulanic acid,can no longer be considered the standard of care,as these drugs are associated with poor outcomes.Theaim of this review is to describe,with an epidemiological focus,the evidence behind this rise in Gram-positive and MDR SBP from 2000 to present,and illustrate potential targeted therapeutic strategies.An appropriate treatment protocol should include daptomycin plus ceftaroline and meropenem,with prompt stepdown to a narrower spectrum when cultures and sensitivity data are available in order to reduce both cost and potential antibiotic resistance development.Marco Fiore Alberto Enrico Maraolo Ivan Gentile Guglielmo Borgia Sebastiano Leone Pasquale Sansone Maria Beatrice Passavanti Caterina Aurilio Maria Caterina Pace 2017World Journal of Hepatology2017,9,30:13

13Role of osteoprotegerin/receptor activator of nuclear factor kappa B/receptor activator of nuclear factor kappa B ligand axis in nonalcoholic fatty liver disease显示文摘Concomitantly with the increase in the prevalences of overweight/obesity, nonalcoholic fatty liver disease(NAFLD) has worldwide become the main cause of chronic liver disease in both adults and children. Patients with fatty liver display features of metabolic syndrome(Met S), like insulin resistance(IR), glucose intolerance, hypertension and dyslipidemia. Recently, epidemiological studies have linked obesity, Met S, and NAFLD to decreased bone mineral density and osteoporosis, highlighting an intricate interplay among bone, adipose tissue, and liver. Osteoprotegerin(OPG), an important symbol of the receptor activator of nuclear factor-B ligand/receptor activator of nuclear factor kappa B/OPG system activation, typically considered for its role in bone metabolism, may also play critical roles in the initiation and perpetuation of obesityrelated comorbidities. Clinical data have indicated that OPG concentrations are associated with hypertension, left ventricular hypertrophy, vascular calcification, endothelial dysfunction, and severity of liver damage in chronic hepatitis C. Nonetheless, the relationship between circulating OPG and IR as a key feature of Met S as well as between OPG and NAFLD remains uncertain. Thus, the aims of the present review are to provide the existent knowledge on these associations and to discuss briefly the underlying mechanisms linking OPG and NAFLD.Lucia Pacifico Gian Marco Andreoli Miriam D'Avanzo Delia De Mitri Pasquale Pierimarchi 2018World Journal of Gastroenterology2018,24,19:11
14Evidence-based medicine: An update on treatments for peritoneal dialysis-related peritonitis显示文摘Peritonitis continues to be a major complication of peritoneal dialysis(PD), and adequate treatment is crucial for a favorable outcome. There is no consensus regarding the optimal therapeutic regimen, and few prospective controlled studies have been published. The objective of this manuscript is to review the results of PD peritonitis treatment reported in narrative reviews, systematic reviews, and proportional meta-analyses. Two narrative reviews, the only existing systematic review and its update published between 1991 and 2014 were included. In addition, we reported the results of a proportional metaanalysis published by our group. Results from systematic reviews of randomized control trials(RCT) and quasiRCT were not able to identify any optimal antimicrobial treatment, but glycopeptide regimens were more likely to achieve a complete cure than a first generation cephalosporin. Compared to urokinase, simultaneous catheter removal and replacement resulted in better outcomes. Continuous and intermittent IP antibiotic use had similar outcomes. Intraperitoneal antibiotics were superior to intravenous antibiotics in reducing treatment failure. In the proportional meta-analysis of RCTs and the case series, the resolution rate(86%) of ceftazidime plus glycopeptide as initial treatment was significantly higher than first generation cephalosporin plus aminoglycosides(66%) and glycopeptides plus aminoglycosides(75%). Other comparisons of regimens used for either initial treatment or treatment of gram-positive rods or gramnegative rods did not show statistically significant differences. The superiority of a combination of a glycopeptide and a third generation cephalosporin was also reported by a narrative review study published in 1991, which reported an 88% resolution rate.Pasqual Barretti Joo Vitor Pereira Doles Douglas Gonalves Pinotti Regina Paolucci El Dib 2015World Journal of Nephrology2015,4,2:9
15Polymer-coated nanoporous carbons for trace seawater uranium adsorption显示文摘Polymer-coated mesoporous carbon nanocomposites were prepared from the immobilization of acrylonitrile and acrylic acid copolymers with divinylbenzene as a crosslinker onto a mesoporous carbon framework.High surface areas were maintained after polymerization with accessible porosity.This functional nanocomposite was tested as an adsorbent for uranium from high salinity solutions.Uranium adsorption results have shown that the adsorption capacities are strongly influenced by the density of the amidoxime groups and the specific surface area.YUE YanFeng SUN XiaoGuang MAYES Richard T.

16Nosocomial spontaneous bacterial peritonitis antibiotic treatment in the era of multi-drug resistance pathogens: A systematic review显示文摘AIM To systematically review literature upon aetiology of nosocomial spontaneous bacterial peritonitis(N-SBP) given the rising importance of multidrug-resistant(MDR) bacteria.METHODS A literature search was performed on MEDLINE and Google Scholar databases from 2000 to 15 th of November 2016, using the following search strategy: 'spontaneous' AND 'peritonitis'.RESULTS The initial search through electronic databases retrieved 2556 records. After removing duplicates, 1958 records remained. One thousand seven hundred and thirty-five of them were excluded on the basis of the screening of titles and abstract, and the ensuing number of remaining articles was 223. Of these records, after careful evaluation, only 9 were included in the qualitative analysis. The overall proportion of MDR bacteria turned out to be from 22% to 73% of cases across the studies.CONCLUSION N-SBP is caused, in a remarkable proportion, by MDR pathogens. This should prompt a careful re-assessment of guidelines addressing the treatment of this clinical entity.Marco Fiore Alberto Enrico Maraolo Ivan Gentile Guglielmo Borgia Sebastiano Leone Pasquale Sansone Maria Beatrice Passavanti Caterina Aurilio Maria Caterina Pace 2017World Journal of Gastroenterology2017,23,25:9
17Liver resection versus radiofrequency ablation in the treatment of cirrhotic patients with hepatocellular carcinoma显示文摘BACKGROUND: Hepatocellular carcinoma is the most common type of primary liver tumor and its incidence is increasing worldwide. The study aimed to compare patients subjected to liver resection or radiofrequency ablation. METHODS: One hundred and forty cirrhotic patients in stage A or B of Child-Pugh with single nodular or multinodular hepatocellular carcinoma were included in this retrospective study. Among them, 87 underwent surgical resection, and 53 underwent percutaneous radiofrequency ablation. Patient charac-teristics, survival, and recurrence-free survival were analyzed. RESULTS: Recurrence-free survival was longer in the resection group in comparison to the radiofrequency group with a median recurrence-free time of 36 versus 26 months, respectively (P=0.01, HR=1.52, 95% CI: 1.05-2.25). In the resection group, median survival was 46 months, with the 1-, 3- and 5-year survival rates of 89.7%, 72.4% and 40.2%. In the radiofrequency group, median survival was 32 months, with the 1-, 3- and 5-year survival rates of 83.0%, 43.4% and 22.6% (P<0.01). CONCLUSIONS: Surgical resection improves the overall survival and recurrence-free survival in comparison with radiofrequency ablation. New evidences are needed to define the real role of the percutaneous technique as an alternative to surgery.Amilcare Parisi Jacopo Desiderio Stefano Trastulli Elisa Castellani Rosario Pasquale Roberto Cirocchi Carlo Boselli Giuseppe Noya 2013Hepatobiliary & Pancreatic Diseases International2013,12,3:8
18Strategies for reducing speckle noise in digital holography显示文摘Digital holography(DH)has emerged as one of the most effective coherent imaging technologies.The technological developments of digital sensors and optical elements have made DH the primary approach in several research fields,from quantitative phase imaging to optical metrology and 3D display technologies,to name a few.Like many other digital imaging techniques,DH must cope with the issue of speckle artifacts,due to the coherent nature of the required light sources.Despite the complexity of the recently proposed de-speckling methods,many have not yet attained the required level of effectiveness.That is,a universal denoising strategy for completely suppressing holographic noise has not yet been established.Thus the removal of speckle noise from holographic images represents a bottleneck for the entire optics and photonics scientific community.This review article provides a broad discussion about the noise issue in DH,with the aim of covering the best-performing noise reduction approaches that have been proposed so far.Quantitative comparisons among these approaches will be presented.Vittorio Bianco Pasquale Memmolo Marco Leo Silvio Montresor Cosimo Distante Melania Paturzo Pascal Picart Bahram Javidi Pietro Ferraro 2018Light(Science & Applications)2018,7,1:8
19Food allergy in gastroenterologic diseases:Review of literature显示文摘Food allergy is a common and increasing problem worldwide. The newly-found knowledge might provide novel experimental strategies, especially for laboratory diagnosis. Approximately 20% of the population alters their diet for a perceived adverse reaction to food, but the application of double-blind placebo-controlled oral food challenge, the “gold standard” for diagnosis of food allergy, shows that questionnaire-based studies over- estimate the prevalence of food allergies. The clinical disorders determined by adverse reactions to food can be classified on the basis of immunologic or nonimmu- nologic mechanisms and the organ system or systems affected. Diagnosis of food allergy is based on clinical history, skin prick tests, and laboratory tests to detect serum-food specific IgE, elimination diets and challeng- es. The primary therapy for food allergy is to avoid the responsible food. Antihistamines might partially relieve oral allergy syndrome and IgE-mediated skin symptoms, but they do not block systemic reactions. Systemic cor- ticosteroids are generally effective in treating chronic IgE-mediated disorders. Epinephrine is the mainstay of treatment for anaphylaxis. Experimental therapies for IgE-mediated food allergy have been evaluated, such as humanized IgG anti-IgE antibodies and allergen specific immunotherapy.Pasquale Mansueto Giuseppe Montalto Maria Luisa Pacor Maria Esposito-Pellitteri Vito Ditta Claudia Lo Bianco Stefania Maria Leto-Barone Gabriele Di Lorenzo 2006World Journal of Gastroenterology2006,12,48:7
20Clinical impact of selective transarterial chemoembolization on hepatocellular carcinoma:A cohort study显示文摘AIM:To prospectively evaluate the short and long term clinical impact of selective transarterial chemoembolization (TACE) on liver function in patients with hepatocellular carcinoma (HCC).To assess side effects in relation to treatments.To analyze the overall survival and HCC progression free survival probability. METHODS:One hundred and seventeen cirrhotic patients with HCC were enrolled.Baseline liver function included Child-Pugh score and serum levels of alanineaminotransferase (ALT),prothrombin time(PT)and bilirubin.According to Cancer Liver Italian Program (CLIP) and Barcelona Clinic Liver Cancer (BCLC) staging systems,71 patients were eligible for TACE; 32 had previously received treatment for HCC.No significant differences in liver function were observed between previously treated and not treated patients. TACE was performed by selective catheterization of the arteries nourishing the lesions.While hospitalized, patient sunder went clinical,hematologicand ultrasonographic assessments.One month after TACE a CT scan was performed to assess tumor response. A second TACE was performed'on demand'.Liver function tests were checked in all patients every four months.RESULTS:After first TACE,the mean Child-Pugh score increased from a mean baseline 5.62±1.12 to 6.11±1.57 at discharge time (P<0.0001),decreasing after four months to 5.81±0.73 (not significant).ALT,PT and bilirubin significantly (P<0.0001)increased 24 h after TACE and progressively decreased until discharge. After the second TACE,variations in Child-Pugh score,ALT,PT and bilirubin were comparable to that described after the first TACE.No major complications were observed.The mean follow-up was 14.7±6.3 mo (median:16 mo).Only one patient died.No other patient experienced important long term worsening of clinical status.The overall survival probability at twenty-four months was 98.18%with a correspondent HCC progression free survival probability of 69%. CONCLUSION:Selectiv TAC Emayproduce significant,but transitory increases in ALT values, with no major impact on liver function and Child-Pugh score.Preservation of liver function is achievable also in patients previously treated with other therapeutic modalities and in patients undergoing multiple TACE cycles.Liver function can remain stable in the long-term, with optimal medium term survival.This result can be achieved through rigorous patient selection on the basis of tumour characteristics and clinical conditions.Rodolfo Sacco Marco Bertini Pasquale Petruzzi Michele Bertoni Irene Bargellini Giampaolo Bresci Graziana Federici Luigi Gambardella Salvatore Metrangolo Giuseppe Parisi Antonio Romano Antonio Scaramuzzino Emanuele Tumino Alessandro Silvestri Emanuele Altomare Claudio Vignali Alfonso Capria 2009World Journal of Gastroenterology2009,15,15:7
