1Role of microRNAs in translation regulation and cancer显示文摘MicroRNAs(miRNAs) are pervasively expressed and regulate most biological functions. They function by modulating transcriptional and translational programs and therefore they orchestrate both physiological and pathological processes, such as development, cell differentiation, proliferation, apoptosis and tumor growth. miRNAs work as small guide molecules in RNA silencing, by negatively regulating the expression of several genes both at mRNA and protein level, by degrading their mRNA target and/or by silencing translation. One of the most recent advances in the field is the comprehension of their role in oncogenesis. The number of miRNA genes is increasing and an alteration in the level of miRNAs is involved in the initiation, progression and metastases formation of several tumors. Some tumor types show a distinct miRNA signature that distinguishes them from normal tissues and from other cancer types. Genetic and biochemical evidence supports the essential role of miRNAs in tumor development. Although the abnormal expression of miRNAs in cancer cells is a widely accepted phenomenon, the cause of this dysregulation is still unknown. Here, we discuss the biogenesis of miRNAs, focusing on the mechanisms by which they regulate protein synthesis. In addition we debate on their role in cancer, highlighting their potential to become therapeutic targets.Stefania Oliveto Marilena Mancino Nicola Manfrini Stefano Biffo 2017World Journal of Biological Chemistry2017,8,1:60
2An Overview of Autism Spectrum Disorder, Heterogeneity and Treatment Options显示文摘Since the documented observations of Kanner in1943, there has been great debate about the diagnoses, the sub-types, and the diagnostic threshold that relates to what is now known as autism spectrum disorder(ASD).Re?ecting this complicated history, there has been continual re?nement from DSM-III with ‘Infantile Autism' to the current DSM-V diagnosis. The disorder is now widely accepted as a complex, pervasive, heterogeneous condition with multiple etiologies, sub-types, and developmental trajectories. Diagnosis remains based on observation of atypical behaviors, with criteria of persistent de?cits in social communication and restricted and repetitive patterns of behavior. This review provides a broad overview of the history, prevalence, etiology, clinical presentation, and heterogeneity of ASD. Factors contributing to heterogeneity, including genetic variability, comorbidity, and gender are reviewed. We then explore current evidencebased pharmacological and behavioral treatments for ASD and highlight the complexities of conducting clinical trials that evaluate therapeutic ef?cacy in ASD populations.Finally, we discuss the potential of a new wave of research examining objective biomarkers to facilitate the evaluation of sub-typing, diagnosis, and treatment response in ASD.Anne Masi Marilena M.De Mayo Nicholas Glozier Adam J.Guastella 2017Neuroscience Bulletin2017,33,2:33
3Patients with primary biliary cirrhosis have increased serum total antioxidant capacity measured with the crocin bleaching assay显示文摘AIM: The balance between oxidants and antioxidants can play an important role in the initiation and development of liver diseases. Recently, we have described a new automated method for the determination of total antioxidant capacity (TAC) in human serum and plasma.METHODS: We measured TAC and corrected TAC (CTAC -abstraction of interactions due to endogenous uric acid,bilirubin and albumin) in 52 patients with chronic liver diseases (41 patients with primary biliary cirrhosis (PBC),10 patients with chronic hepatitis C and 13 patients with viral HCV cirrhosis) as well as in 10 healthy controls. In 23 PBC patients measurement were also done 6 mo after treatment with ursodeoxycholic acid (UDCA). The TAC assay was based on a modification of the crocin bleaching assay. The results were correlated with routine laboratory measurements and the histological stage of PBC.RESULTS: There were no significant differences in TAC between the various groups. However, CTAC was considerably increased in the PBC group compared to controls and cirrhotics. Analysis of these patients according to disease stages showed that this increase was an early phenomenon observed only in stages Ⅰ and Ⅱ compared to controls, cirrhotics and patients with chronic hepatitis C).After 6 mo of treatment with UDCA, levels of CTAC decreased to those similar to that of controls.CONCLUSION: Patients in the early stages of PBC present with high levels of corrected total antioxidant capacity and this maybe related to the pathophysiology of the disease. UDCA treatment restores the levels of CTAC to control levels.George Notas Niki Miliaraki Marilena Kampa Fillipos Dimoulios Erminia Matrella Adam Hatzidakis Elias Castanas Elias Kouroumalis 2005World Journal of Gastroenterology2005,11,27:13

5Acute alcoholic hepatitis, end stage alcoholic liver disease and liver transplantation: An Italian position statement显示文摘Alcoholic liver disease encompasses a broad spectrum of diseases ranging from steatosis steatohepatitis,fibrosis,and cirrhosis to hepatocellular carcinoma.Forty-four per cent of all deaths from cirrhosis are attributed to alcohol.Alcoholic liver disease is the second most common diagnosis among patients undergoing liver transplantation(LT).The vast majority of transplant programmes(85%)require 6 mo of abstinence prior to transplantation;commonly referred to as the'6-mo rule'.Both in the case of progressive end-stage liver disease(ESLD)and in the case of severe acute alcoholic hepatitis(AAH),not responding to medical therapy,there is a lack of evidence to support a 6-mo sobriety period.It is necessary to identify other risk factors that could be associated with the resumption of alcohol drinking.The'Group of Italian Regions'suggests that:in a case of ESLD with model for end-stage liver disease<19 a 6-mo abstinence period is required;in a case of ESLD,a 3-mo sober period before LT may be more ideal than a 6-mo period,in selected patients;and in a case of severe AAH,not respond-ing to medical therapies(up to 70%of patients die within 6 mo),LT is mandatory,even without achieving abstinence.The multidisciplinary transplant team must include an addiction specialist/hepato-alcohologist.Patients have to participate in self-help groups.Gianni Testino Patrizia Burra Ferruccio Bonino Francesco Piani Alessandro Sumberaz Roberto Peressutti Andrea Giannelli Castiglione Valentino Patussi Tiziana Fanucchi Ornella Ancarani Giovanna De Cerce Anna Teresa Iannini Giovanni Greco Antonio Mosti Marilena Durante Paola Babocci Mariano Quartini Davide Mioni Sarino Aricò Aniello Baselice Silvia Leone Fabiola Lozer Emanuele Scafato Paolo Borro 2014World Journal of Gastroenterology2014,20,40:5
6Liver hemangioma and vascular liver diseases in patients with systemic lupus erythematosus显示文摘AIM:To investigate whether systemic lupus erythematosus (SLE) is associated with benign focal liver lesions and vascular liver diseases, since these have been occasionally reported in SLE patients. METHODS:Thirty-five consecutive adult patients with SLE and 35 age-and sex-matched healthy controls were evaluated. Hepatic and portal vein patency and presence of focal liver lesions were studied by colour-Doppler ultrasound, computerized tomography and magnetic resonance were used to refine the diagnosis, clinical data of SLE patients were reviewed. RESULTS:Benign hepatic lesions were common in SLE patients (54% vs 14% controls, P < 0.0001), withhemangioma being the most commonly observed lesion in the two groups. SLE was associated with the presence of single hemangioma [odds ratios (OR) 5.05; 95% confidence interval (CI) 1.91-13.38] and multiple hemangiomas (OR 4.13; 95% CI 1.03-16.55). Multiple hemangiomas were associated with a longer duration of SLE (9.9 ± 6.5 vs 5.5 ± 6.4 years; P = 0.04). Imaging prior to SLE onset was available in 9 patients with SLE and hemangioma, showing absence of lesions in 7/9. The clinical data of our patients suggest that SLE pos- sibly plays a role in the development of hemangioma. In addition, a Budd-Chiari syndrome associated with nodular regenerative hyperplasia (NRH), and a NRH associated with hepatic hemangioma were observed, both in patients hospitalized for abdominal symptoms, suggesting that vascular liver diseases should be specifically investigated in this population. CONCLUSION:SLE is associated with 5-fold increased odds of liver hemangiomas, suggesting that these might be considered among the hepatic manifestations of SLE.Annalisa Berzigotti Marilena Frigato Elena Manfredini Lucia Pierpaoli Rita Mulè Carolina Tiani Paola Zappoli Donatella Magalotti Nazzarena Malavolta Marco Zoli 2011World Journal of Gastroenterology2011,17,40:5
7Ovarian cancer standard of care: are there real alternatives?显示文摘Ovarian cancer remains a major issue for gynecological oncologists, and most patients are diagnosed when the disease is already advanced with a poor chance of survival. Debulking surgery followed by platinum-taxane chemotherapy is the current standard of care, but based on several different strategies currently under evaluation, some encouraging data have been published in the last 4 to 5 years. This review provides a state-of-the-art overview of the available alternatives to conventional treatment and the most promising new combinations. For example, neoadjuvant chemotherapy does not seem to be inferior to primary debulking. Despite its outcome improvements, intraperitoneal chemotherapy struggles for acceptance due to the heavy toxicity. Dose-dense chemotherapy, after showing an impressive efficacy in Asian populations, has not produced equal results in a European cohort, and the results of alternative platinum doublets are not superior to those of carboplatin and paclitaxel. In this setting, adherence to a maintenance therapy after first-line treatment and multiple(primarily antiangiogenic) agents appears to be effective. Although many questions, including the duration of maintenance treatment and the use of bevacizumab beyond progression, remain unanswered, new biologic agents, such as poly(ADP-ribose) polymerase(PARP) inhibitors, nintedanib, and mitogen-activated protein/extracellular signal-regulated kinase(MEK) inhibitors, have emerged as potential therapeutic options in the very near future. Based on the multiplicity of available strategies, the histological and molecular features of the tumor, in addition to patient's clinical condition and disease state, continue to gain importance in guiding treatment choices.Chiara Della Pepa Giuseppe Tonini Carmela Pisano Marilena Di Napoli Sabrina Chiara Cecere Rosa Tambaro Gaetano Facchini Sando Pignata 2015Chinese Journal of Cancer2015,34,1:5
8Analysis of predictor equations for determining the blast-induced vibration in rock blasting显示文摘The paper proposes a new empirical correlation designed to complement the‘‘site laws'currently used to evaluate the attenuation in the rock masses of vibrations induced by rock blasting.The formula contains a deformed exponential known as the K-exponential,which seems to well represent a large number of both natural and artificial phenomena ranging from astrophysics to quantum mechanics,with some extension in the field of economics and finance.Experimental validation of the formula was performed via the analysis of vibration data covering a number of case studies,which differed in terms of both operation and rock type.A total of 12 experimental cases were analysed and the proposed formulation exhibited a good performance in 11 of them.In particular,the proposed law,which was built using blast test data,produced very good approximations of the points representing the vibration measurements and would thus be useful in organising production blasts.However,the developed formula was found to work less well when a correlation obtained for a given site was applied to another presenting similar types of rocks and operations,and thus should not be employed in the absence of measurements from test data.Marilena Cardu Dario Coragliotto Pierpaolo Oreste 2019International Journal of Mining Science and Technology2019,29,6:4
9Lack of association between seroprevalence of Helicobacterpylori infection and primary biliary cirrhosis显示文摘AIM: To determine the association between seroprevalence of Helicobacter pylori(Hpylon) infection and primary biliary cirrhosis (PBC).METHODS: In this case-control study, 149 consecutive patients (10 males, 139 females, mean age 58.2+11 years, range 26-82 years) suffering from PBC and 619 consecutive healthy volunteer blood donors (523 males, 96 females, mean age 47±5.3 years, range 18-65 years) attending the Hospital Blood Bank and residing in the same area were recruited. A commercial enzyme linked immunosorbent assay was used to detect anti-Hpylori(IgG) antibodies in serum.RESULTS: Antibodies to Hpyloriwere present in 78 (52.3%) out of 149 PBC-patients and in 291 (47%) out of 619 volunteers (P= 0.24, OR 1.24, 95% CI 0.85-1.80). In the subjects less than 60 years old, the prevalence of Hpylori infection among PBC-patients (40/79) was slightly higher than in controls (50.6% vs46.2%) P= 0.46, OR = 1.19, 95% CI: 0.72-1.95). In those over 60 years, the prevalence of H pyloriinfection was similar between PBC-patients and controls (54.2% vs57.8%, P= 0.7, OR 0.86, 95% CI 0.36-2.07). CONCLUSION: There is no association between seroprevalence of Hpyloriinfection and primary biliary cirrhosis.Marilena Durazzo Floriano Rosina Alberto Premoli Enrico Morello Sharmila Fagoonee Rosaria Innarella Enrico Solerio Rinaldo Pellicano Mario Rizzetto 2004World Journal of Gastroenterology2004,10,21:4

11Gender specific medicine in liver diseases:a point of view显示文摘Gender medicine focuses on the patho-physiological,clinical,prevention and treatment differences in diseases that are equally represented in men and women.The purpose of gender medicine is to ensure that each individual man and woman receives the best treatment possible based on scientific evidence.The concept of'gender'includes not only the sexual characteristics of individuals but also physiological and psychological attributes of men and women,including risk factors,protective/aggravating effects of sexual hormones and variances linked to genetics and corporal structures that explain biological and physiological differences between men and women.It is very important to consider all the biological,physiological,functional,psychological,social and cultural characteristics to provide patients with individualized disease management.Herein,we critically analyze the literature regarding gender differences for diseases and acquired conditions of the most representative hepatic pathologies:primary biliary cirrhosis,autoimmune hepatitis,primary sclerosing cholangitis,non alcoholic fatty liver disease and alcoholic liver disease,and viral chronic hepatitis B and C.The last section addresses hemochromatosis,which is a prevalent iron overload disorder in the Caucasian population.This review aims to describe data from the literature concerning viral chronic hepatitis during pregnancy,management during pregnancy and delivery,and new effective drugs for the prevention of maternal infection transmission without significant adverse effects or complications.Marilena Durazzo Paola Belci Alessandro Collo Vanessa Prandi Erika Pistone Maria Martorana Roberto Gambino Simona Bo 2014World Journal of Gastroenterology2014,20,9:3
12非物质文化遗产与抹除:对文化保护与当代博物馆实践的再思考显示文摘非物质文化遗产这一概念在国际遗产保护界的提出,正与文化同质化的担忧以及保护世界多样性的需求相关。联合国教科文组织制定的规范性框架是否会导致文化被当作一套濒临消亡的生活方式而体制化,正是许多批评者提出的疑问。本文联系遗产抹除机制和遗产毁坏与恢复之间的创造性交互作用,回顾了体制化的文化保护办法,再以两个迥异的公共空间即新西兰国家博物馆(蒂帕帕博物馆)与巴黎的凯布朗利博物馆中的原住民身份政治为背景,对这些办法进行了检视。Marilena Alivizatou 高菲 2013文化艺术研究2013,6,3:3
13Complexity analysis of blast-induced vibrations in underground mining: A case study显示文摘Blasting in geological bodies is an industrial process acting in an environment characterized by high uncertainties (natural joints, faults, voids, abrupt structural changes), which are transposed into the process parameters (e.g. energetic transfer to rock mass, hole deviations, misfires, vibrations, fly-rock, etc.). The approach to this problem searching for the 'optimum' result can be ineffective. The geological environment is marked out by too many uncertainties, to have an 'optimum' suitable to different applications. Researching for 'Robustness' in a blast design gives rise to much more efficiency. Robustness is the capability of the system to behave constantly under varying conditions, without leading to unexpected results. Since the geology varies from site to site, setting a robust method can grant better results in varying environments, lowering the costs and increasing benefits and safety. Complexity Analysis (C.A.) is an innovative approach to systems. C.A. allows analyzing the Complexity of the Blast System and the criticality of each variable (drilling, charging and initiation parameters). The lower is the complexity, the more robust is the system, and the lower is the possibility of unexpected results. The paper presents the results obtained thanks to the C.A. approach in an underground gypsum quarry (Italy), exploited by conventional rooms and pillars method by drilling and blasting. The application of C.A. led to a reliable solution to reduce the charge per delay, hence reducing the impact of ground vibration on the surrounding structures. The analysis of the correlation degree between the variables allowed recognizing empirical laws as well.Cardu Marilena Dompieri Mauricio Seccatore Jacopo 2012International Journal of Mining Science and Technology2012,22,1:3

15Hepatitis delta virus: From infection to new therapeutic strategies显示文摘The hepatitis delta virus(HDV)is a small RNA virus that encodes a single protein and which requires the hepatitis B virus(HBV)-encoded hepatitis B surface antigen(HBsAg)for its assembly and transmission.HBV/HDV co-infections exist worldwide and show a higher prevalence among selected groups of HBV-infected populations,specifically intravenous drug users,practitioners of high-risk sexual behaviours,and patients with cirrhosis and hepatocellular carcinoma.The chronic form of HDV-related hepatitis is usually severe and rapidly progressive.Patterns of the viral infection itself,including the status of co-infection or super-infection,virus genotypes(both for HBV and HDV),and persistence of the virus’replication,influence the outcome of the accompanying and manifested liver disease.Unfortunately,disease severity is burdened by the lack of an effective cure for either virus type.For decades,the main treatment option has been interferon,administered as mono-therapy or in combination with nucleos(t)ide analogues.While its efficacy has been reported for different doses,durations and courses,only a minority of patients achieve a sustained response,which is the foundation of eventual improvement in related liver fibrosis.The need for an efficient therapeutic alternative remains.Research efforts towards this end have led to new treatment options that target specific steps in the HDV life cycle;the most promising among these are myrcludex B,which inhibits virus entry into hepatocytes,lonafarnib,which inhibits farnesylation of the viral-encoded LHDAg large hepatitis D antigen,and REP-2139,which interferes with HBsAg release and assembly.Grazia A Niro Arianna Ferro Francesca Cicerchia Isabella Brascugli Marilena Durazzo 2021World Journal of Gastroenterology2021,27,24:2
16Associations between y-glutamyl transferase, metabolic abnormalities and inflammation in healthy subjects from a population-based cohort: A possible implication for oxidative stress显示文摘AIM: To examine the relationships between γ -glutamyltransferase (GGT), alanine-aminotransferase (ALT),aspartate-aminotransferase (AST) and various metabolic parameters, C-reactive protein (CRP) and an oxidative stress marker (nitrotyrosine, NT) in subjects without any metabolic abnormalities from a population-based sample.METHODS: Two hundred and five subjects with normal body mass index (BMI), glucose tolerance, and without any metabolic abnormality were studied out of 1339subjects, without known liver diseases, alcohol abuse or use of hepatotoxic drugs, who are representative of the 45-64 aged population of Asti (north-western Italy).RESULTS: In all patients metabolic parameters and hs-CRP levels linearly increase from the lowest to the highest ALT and GGT tertiles, while in subjects without metabolic abnormalities, there is a significant association between fasting glucose, uric acid, waist circumference,hs-CRP, triglyceride values, and GGT levels. In these subjects, male sex, higher hs-CRP and glucose levels are associated with GGT levels in a multiple regression model, after adjustments for multiple confounders.In the same model, median NT levels are significantly associated with the increasing GGT tertile (β = 1.06;95%CI 0.67-1.45), but not with the AST and ALT tertiles.In a multiple regression model, after adjusting for age,sex, BMI, waist, smoking, and alcohol consumption, both NT (β = 0.05; 95%CI 0.02-0.08) and hs-CRP levels (β =0.09; 95%CI 0.03-0.15) are significantly associated with fasting glycemia.CONCLUSION: GGT, an easy, universally standardized and available measurement, could represent an early marker of sub-clinical inflammation and oxidative stress in otherwise healthy individuals. Prospective studies are needed to establish if GGT could predict future diabetes in these subjects.Simona Bo Roberto Gambino Marilena Durazzo Sabrina Guidi Elisa Tiozzo Federica Ghione Luigi Gentile Maurizio Cassader Gian Franco Pagano 2005World Journal of Gastroenterology2005,11,45:2
