| 1 | Treatment of gastric cancer显示文摘The authors focused on the current surgical treatment of resectable gastric cancer,and significance of periand post-operative chemo or chemoradiation.Gastric cancer is the 4thmost commonly diagnosed cancer and the second leading cause of cancer death worldwide.Surgery remains the only curative therapy,while perioperative and adjuvant chemotherapy,as well as chemoradiation,can improve outcome of resectable gastric cancer with extended lymph node dissection.More than half of radically resected gastric cancer patients relapse locally or with distant metastases,or receive the diagnosis of gastric cancer when tumor is disseminated;therefore,median survival rarely exceeds12 mo,and 5-years survival is less than 10%.Cisplatin and fluoropyrimidine-based chemotherapy,with addition of trastuzumab in human epidermal growth factor receptor 2 positive patients,is the widely used treatment in stageⅣpatients fit for chemotherapy.Recent evidence supports the use of second-line chemotherapy after progression in patients with good performance | Michele Orditura Gennaro Galizia Vincenzo Sforza Valentina Gambardella Alessio Fabozzi Maria Maddalena Laterza Francesca Andreozzi Jole Ventriglia Beatrice Savastano Andrea Mabilia Eva Lieto Fortunato Ciardiello Ferdinando De Vita | 2014 | World Journal of Gastroenterology2014，20，7： | 116 |
| 2 | Management of ruptured hepatocellular carcinoma:Implications for therapy显示文摘AIM:To assess the treatment and tumor-related variables associated with outcome after treatment of spontaneously ruptured hepatocellular carcinoma (HCC).METHODS: Patients with ruptured HCC were identif ied. The complications, mortality and survival were assessed. The relationship between tumor size and the severity of hemoperitoneum and between tumor size and grade were examined.RESULTS: From January 1993 to January 2008, 556 patients with HCC with or without cirrhosis were evaluated; of which, 16 (2.87%) presented with spontaneous rupture. All but 1 patient had cirrhosis. Twelve patients underwent surgical resection while 4 underwent trans-cutaneous arterial catheter embolization (TAE) (trans-cutaneous arterial embolization). Early mortality (<30 d) was 25% (4 of 16) and was inversely relatedto Child-Pugh score; 3 of the 4 early deaths occurred in patients treated with TAE with 1 of 12 occurring in the resected group. There was no correlation between tumor size and grade or between size and severity of hemoperitoneum.CONCLUSION: Tumor size did not correlate with severity of the hemoperitoneum. There was an inverse relationship between G1-G3 (grade of cellular differentiation) HCC and dimensions. | Nicolò Bassi Ezio Caratozzolo Luca Bonariol Cesare Ruffolo Alessio Bridda Luigi Padoan Michele Antoniutti Marco Massani | 2010 | World Journal of Gastroenterology2010，16，10： | 26 |
| 3 | Hepatitis B virus burden in developing countries显示文摘Hepatitis B virus(HBV) infection has shown an intermediate or high endemicity level in low-income countries over the last five decades. In recent years, however, the incidence of acute hepatitis B and the prevalence of hepatitis B surface antigen chronic carriers have decreased in several countries because of the HBV universal vaccination programs started in the nineties. Some countries, however, are still unable to implement these programs, particularly in their hyperendemic rural areas. The diffusion of HBV infection is still wide in several low-income countries where the prevention, management and treatment of HBV infection are a heavy burden for the governments and healthcare authorities. Of note, the information on the HBV epidemiology is scanty in numerous eastern European and Latin-American countries. The studies on molecular epidemiology performed in some countries provide an important contribution for a more comprehensive knowledge of HBV epidemiology, and phylogenetic studies provide information on the impact of recent and older migratory flows. | Rosa Zampino Adriana Boemio Caterina Sagnelli Loredana Alessio Luigi Elio Adinolfi Evangelista Sagnelli Nicola Coppola | 2015 | World Journal of Gastroenterology2015，21，42： | 25 |

| 5 | Pharmacogenetic considerations for optimizing tacrolimus dosing in liver and kidney transplant patients显示文摘The introduction of tacrolimus in clinical practice has improved patient survival after organ transplant.However,despite the long use of tacrolimus in clinical practice,the best way to use this agent is still a matter of intense debate.The start of the genomic era has generated new research areas,such as pharmacogenetics,which studies the variability of drug response in relation to the genetic factors involved in the processes responsible for the pharmacokinetics and/or the action mechanism of a drug in the body.This variability seems to be correlated with the presence of genetic polymorphisms.Genotyping is an attractive option especially for the initiation of the dosing of tacrolimus;also,unlike phenotypic tests,the genotype is a stable characteristic that needs to be determined only once for any given gene.However,prospective clinical studies must show that genotype determination before transplantation allows for better use of a given drug and improves the safety and clinical efficacy of that medication.At present,research has been able to reliably show that the CYP3A5 genotype,but not the CYP3A4 or ABCB1 ones,can modify the pharmacokinetics of tacrolimus.However,it has not been possible to incontrovertibly show that the corresponding changes in the pharmacokinetic profile are linked with different patient outcomes regarding tacrolimus efficacy and toxicity.For these reasons,pharmacogenetics and individualized medicine remain a fascinating area for further study and may ultimately become the face of future medical practice and drug dosing. | Alessio Provenzani Andrew Santeusanio Erin Mathis Monica Notarbartolo Manuela Labbozzetta Paola Poma Ambra Provenzani Carlo Polidori Giovanni Vizzini Piera Polidori Natale D'Alessandro | 2013 | World Journal of Gastroenterology2013，19，48： | 15 |
| 6 | Clinical management of advanced gastric cancer: The role of new molecular drugs显示文摘Gastric cancer is the fourth most common malignant neoplasm and the second leading cause of death for cancer in Western countries with more than 20000 new cases yearly diagnosed in the United States.Surgery represents the main approach for this disease but,notwithstanding the advances in surgical techniques,we observed a minimal improvement in terms of overall survival with a significant increasing of relapsing disease rates.Despite the development of new drugs has significantly improved the effectiveness of chemothera-py,the prognosis of patients with unresectable or metastatic gastric adenocarcinoma remains poor.Recently,several molecular target agents have been investigated;in particular,trastuzumab represents the first target molecule showing improvements in overall survival in human epithelial growth factor 2-positive gastric cancer patients.New molecules targeting vascular epithelial growth factor,mammalian target of rapamycin,and anti hepatocyte growth factor-c-Met pathway are also under investigation,with interesting results.Anyway,it seems necessary to select more accurately the population to treat with new agents by the identification of new biomarkers in order to optimize the results.In this paper we review the actual'scenario'of targeted treatments,also focusing on the new agents in development for gastric cancer and gastro-esophageal carcinoma,discussing their efficacy and potential applications in clinical practice. | Ferdinando De Vita Natale Di Martino Alessio Fabozzi Maria Maddalena Laterza Jole Ventriglia Beatrice Savastano Angelica Petrillo Valentina Gambardella Vincenzo Sforza Luigi Marano Annamaria Auricchio Gennaro Galizia Fortunato Ciardiello Michele Orditura | 2014 | World Journal of Gastroenterology2014，20，40： | 12 |
| 7 | Role of liver biopsy in hepatocellular carcinoma显示文摘The role of liver biopsy in the diagnosis of hepatocellular carcinoma(HCC)has been challenged over time by the ability of imaging techniques to characterize liver lesions in patients with known cirrhosis.In fact,in the diagnostic algorithm for this tumor,histology is currently relegated to controversial cases.Furthermore,the risk of complications,such as tumor seeding and bleeding,as well as inadequate sampling have further limited the use of liver biopsy for HCC management.However,there is growing evidence of prognostic and therapeutic information available from microscopic and molecular analysis of HCC and,as the information content of the tissue sample increases,the advantages of liver biopsy might modify the current risk/benefit ratio.We herein review the role and potentiality of liver biopsy in the diagnosis and management of HCC.As the potentiality of precision medicine comes to the management of HCC,it will be crucial to have rapid pathways to define prognosis,and even treatment,by identifying the patients who could most benefit from target-driven therapies.All of the above reasons suggest that the current role of liver biopsy in the management of HCC needs substantial reconsideration. | Luca Di Tommaso Marco Spadaccini Matteo Donadon Nicola Personeni Abubaker Elamin Alessio Aghemo Ana Lleo | 2019 | World Journal of Gastroenterology2019，25，40： | 11 |
| 8 | 沥青体系的分子动力学研究进展及展望显示文摘随着我国道路工程的飞速发展,沥青混凝土在路面工程中有越来越广泛的应用。近年来,沥青材料的研究已不仅局限于宏观性能试验,还拓展到介观与微观层面对沥青材料进行多尺度研究。分子动力学方法属于微观研究方法的一种,它是通过积分算法模拟研究对象在不同条件下的分子运动轨迹与体系能量变化,并分析模拟数据得出结论。该方法已被广泛应用于分子尺度下路面沥青材料设计与微观机理研究,其优势在于从分子运动的角度解释沥青体系的各种现象与性质。因此,许多学者采用宏观试验和分子动力学模拟相结合的多尺度方法研究沥青体系,这将推动沥青材料的进一步发展。本文对沥青体系的分子动力学进行了全面的分析,构建了沥青体系分子动力学模型的一般平衡步骤,提出采用密度、玻璃态转变温度、黏度、溶解度参数等对沥青体系分子动力学模型的有效性进行验证。综合分析了分子动力学方法对沥青纳米聚集、自修复、改性、老化、界面黏附等行为机理的研究进展,提出采用耗散粒子动力学与粗粒化分子动力学对现阶段沥青体系分子动力学的研究尺度进行扩展。研究结果表明,沥青类材料的分子动力学方法还处于早期探索阶段,但其发展潜力极大,利用分子动力学方法研究沥青体系各组分分子的动力学行为,可揭示常规试验无法观察到的分子含时运动规律,预测沥青材料的宏观性能并针对沥青的分子结构提出其路用性能改善措施,从分子尺度上推动沥青路面多尺度试验仿真方法的发展与完善,为沥青材料基因组的开发研究奠定基础。 | 何亮 李冠男 郑雨丰 Alessio Alexiadis Jan Valentin Karol J Kowalski | 2020 | 材料导报2020，34，19： | 10 |
| 9 | Robotic rectal surgery: State of the art显示文摘Laparoscopic rectal surgery has demonstrated its superiority over the open approach, however it still has some technical limitations that lead to the development of robotic platforms. Nevertheless the literature on this topic is rapidly expanding there is still no consensus about benefits of robotic rectal cancer surgery over the laparoscopic one. For this reason a review of all the literature examining robotic surgery for rectal cancer was performed. Two reviewers independently conducted a search of electronic databases(Pub Med and EMBASE) using the key words 'rectum', 'rectal', 'cancer', 'laparoscopy', 'robot'. After the initial screen of 266 articles, 43 papers were selected for review. A total of 3013 patients were included in the review. The most commonly performed intervention was low anterior resection(1450 patients, 48.1%), followed by anterior resections(997 patients, 33%), ultra-low anterior resections(393 patients, 13%) and abdominoperineal resections(173 patients, 5.7%). Robotic rectal surgery seems to offer potential advantages especially in low anterior resections with lower conversions rates and better preservation of the autonomic function. Quality of mesorectum and status of and circumferential resection margins are similar to those obtained with conventional laparoscopy even if robotic rectal surgery is undoubtedly associated with longer operative times. This review demonstrated that robotic rectal surgery is both safe and feasible but there is no evidence of its superiority over laparoscopy in terms of postoperative, clinical outcomes and incidence of complications. In conclusion robotic rectal surgery seems to overcome some of technical limitations of conventional laparoscopic surgery especially for tumors requiring low and ultralow anterior resections but this technical improvement seems not to provide, until now, any significant clinical advantages to the patients. | Fabio Staderini Caterina Foppa Alessio Minuzzo Benedetta Badii Etleva Qirici Giacomo Trallori Beatrice Mallardi Gabriele Lami Giuseppe Macrì Andrea Bonanomi Siro Bagnoli Giuliano Perigli Fabio Cianchi | 2016 | World Journal of Gastrointestinal Oncology2016，8，11： | 7 |
| 10 | Cystic echinococcosis of the liver and lung treated by radiofrequency thermal ablation:An ex-vivo pilot experimental study in animal models显示文摘AIM:To evaluate radiofrequency thermal ablation (RTA) for treatment of cystic echinococcosis in animal models (explanted organs).METHODS:Infected livers and lungs from slaughtered animals,10 bovine and two ovine,were collected.Cysts were photographed,and their volume,cyst content,germinal layer adhesion status,wall calcification and presence of daughter or adjacent cysts were evaluated by ultrasound.Some cysts were treated with RTA at 150 W,80℃,7 min.Temperature was monitored inside and outside the cyst.A second needle was placed inside the cyst for pressure stabilization.After treatment,all cysts were sectioned and examined by histology.Cysts were defined as alive if a preserved germinal layer at histology was evident,and as successfully treated if the germinal layer was necrotic.RESULTS:The subjects of the study were 17 cysts (nine hepatic and eight pulmonary),who were treated with RTA.Pathology showed 100% success rate in both hepatic (9/9) and lung cysts (8/8);immediate volume reduction of at least 65%;layer of host tissue necrosis outside the cyst,with average extension of 0.64 cm for liver and 1.57 cm for lung;and endocyst attached to the pericystium both in hepatic and lung cysts with small and focal de novo endocyst detachment in just 3/9 hepatic cysts.CONCLUSION:RTA appears to be very effective in killing hydatid cysts of explanted liver and lung.Bile duct and bronchial wall necrosis,persistence of endocyst attached to pericystium,should help avoid or greatly decrease in vivo post-treatment fistula occurrence and consequent overlapping complications that are common after surgery or percutaneous aspiration,injection and reaspiration.In vivo studies are required to confirm and validate this new therapeutic approach. | Vincenzo Lamonaca Antonino Virga Marta Ida Minervini Roberta Di Stefano Alessio Provenzani Pietro Tagliareni Giovanna Fleres Angelo Luca Giovanni Vizzini Ugo Palazzo Bruno Gridelli | 2009 | World Journal of Gastroenterology2009，15，26： | 6 |
| 11 | Is dual therapy the correct strategy in frail elderly patients with atrial fibrillation and acute coronary syndrome?显示文摘Atrial fibrillation(AF)is a very common arrhythmia in clinical practice.Its incidence and prevalence are age-related and are growing in the last years.Age is a risk factor also for coronary artery disease(CAD),and with the evolution of preventive care,the first event(acute coronary syndrome(ACS)or percutaneous coronary intervention(PCI))takes place at a later age.If elderly patients with AF and CAD undergo ACS or PCI,they have indication to assume triple therapy.Triple therapy(oral anticoagulation(OAC)plus dual antiplatelet therapy(DAPT))exposes patients to high bleeding risk.In the last 10 years,several clinical trials have tested dual therapy(OAC plus single antiplatelet therapy)in AF patients who undergo ACS or elective PCI.WOEST trial has tested warfarin+clopidogrel against triple therapy.PIONEER AF-PCI trial has tested low-dose rivaroxaban+P2Y12 inhibitor or very low-dose rivaroxaban+DAPT against standard triple therapy with warfarin.RE-DUAL PCI trial has tested two doses of dabigatran+P2Y12 inhibitor against standard triple therapy with Warfarin.AUGUSTUS trial has tested apixaban against warfarin both in dual therapy with P2Y12 inhibitor and in triple therapy with a P2Y12 inhibitor and aspirin.ENTRUST-AF PCI,last published study,has tested edoxaban+P2Y12 inhibitor against triple therapy.All these trials show dual therapy reduces significantly bleeding risk than triple therapy.In this paper,we analyze these clinical trials to understand if dual therapy results can be applied to elderly patients and what is probably the better approach in elderly AF patients undergo to ACS or PCI. | Alessio Menditto Roberto Antonicelli | 2020 | Journal of Geriatric Cardiology2020，17，1： | 4 |
| 12 | Subcellular localization of alpha-synuclein aggregates and their interaction with membranes显示文摘For more than a decade numerous evidence has been reported on the mechanisms of toxicity of α-synuclein(αS) oligomers and aggregates in α-synucleinopathies.These species were thought to form freely in the cytoplasm but recent reports of αS multimer conformations when bound to synaptic vesicles in physiological conditions,have raised the question about where αS aggregation initiates.In this review we focus on recent literature regarding the impact on membrane binding and subcellular localization of αS toxic species to understand how regular cellular function of αS contributes to pathology.Notably αS has been reported to mainly associate with specific membranes in neurons such as those of synaptic vesicles,ER/Golgi and the mitochondria,while toxic species of αS have been shown to inhibit,among others,neurotransmission,protein trafficking and mitochondrial function.Strategies interfering with αS membrane binding have shown to improve αS-driven toxicity in worms and in mice.Thus,a selective membrane binding that would result in a specific subcellular localization could be the key to understand how aggregation and pathology evolves,pointing out to αS functions that are primarily affected before onset of irreversible damage. | Fabiana Miraglia Alessio Ricci Lucia Rota Emanuela Colla | 2018 | Neural Regeneration Research2018，13，7： | 4 |
| 13 | Acute heart failure in elderly patients:a review of invasive and non-invasive management显示文摘Acute heart failure(AHF)is a major cause of unplanned hospitalisations in the elderly and is associated with high mortality.Its prevalence has grown in the last years due to population aging and longer life expectancy of chronic heart failure patients.Although international societies have provided guidelines for the management of AHF in the general population,scientific evidence for geriatric patients is often lacking,as these are underrepresented in clinical trials.Elderly have a different risk profile with more comorbidities,disability,and frailty,leading to increased morbidity,longer recovery time,higher readmission rates,and higher mortality.Furthermore,therapeutic options are often limited,due to unfeasibility of invasive strategies,mechanical circulatory support and cardiac transplantation.Thus,the in-hospital management of AHF should be tailored to each patient's clinical situation,cardiopulmonary condition and geriatric assessment.Palliative care should be considered in some cases,in order to avoid unnecessary diagnostics and/or treatments.After discharge,a strict follow-up through outpatient clinic or telemedicine is can improve quality of life and reduce rehospitalisation rates.The aim of this review is to offer an insight on current literature and provide a clinically oriented,patient-tailored approach regarding assessment,treatment and follow-up of elderly patients admitted for AHF. | Gregorio Tersalvi Alessio Gasperetti Marco Schiavone Jeroen Dauw Cecilia Gobbi Marialessia Denora Joel Daniel Krul Giacomo Maria Cioffi Gianfranco Mitacchione Giovanni B.Forleo | 2021 | Journal of Geriatric Cardiology2021，18，7： | 4 |
| 14 | Individualized hepatocellular carcinoma risk: The challenges for designing successful chemoprevention strategies显示文摘Hepatocellular carcinoma (HCC) develops in the context of environmental risk factors like chronic viral hepatitis, diabetes and alcohol exposure, often associated to an increased risk of cirrhosis. Antiviral treatments that are effective to counteract hepatitis B and C may also attenuate the risk of tumor development. However, since hepatitis B-related carcinogenesis is promoted independently of the onset of cirrhosis, such antiviral treatments as nucleo(t)side analogs can promote regression of cirrhosis, prevent clinical decompensation and variceal bleeding but not HCC. This means that in successfully treated patients with cirrhosis, HCC is often the consequence of their extended survival. In hepatitis C patients, a sustained virological response to interferon-based therapies can reduce the rate of HCC development, even in patients with cirrhosis who experience histological regression of their liver disease. Future therapies aimed at this endpoint in at risk populations should take into consideration pretreatment patient stratification for host, viral and environmental risk factors. In this context the recent discovery of single nucleotide polymorphisms involved in the immune system function and tumorigenesis, might permit enrollment of populations of patients enriched with HCC risk factors for targeted chemopreventive therapies. This could finally pave the way to personalized algorithms, as already seen in the diagnosis and treatment schemes for chemoprevention. | Cristina Della Corte Alessio Aghemo Massimo Colombo | 2013 | World Journal of Gastroenterology2013，19，9： | 4 |
| 15 | Hepatitis B virus infection in immigrant populations显示文摘Hepatitis B virus(HBV) is the most common cause of hepatitis worldwide, with nearly 350 million people chronically infected and 600000 deaths per year due to acute liver failure occurring during acute hepatitis or, more frequently, in HBV-related liver cirrhosis or hepatocellular carcinoma. Ongoing immigration from countries with a high HBV endemicity to those with a low HBV endemicity warrants particular attention to prevent the spread of HBV infection to the native population. This review article analyzes the epidemiology and virological and clinical characteristics of HBV infection in immigrant populations and in their host countries, and suggests prophylactic measures to prevent the spread of this infection. Among the immigrants from different geographical areas, those from South East Asia and sub-Saharan Africa show the highest prevalences of hepatitis B surface antigen(HBs Ag) carriers, in accordance with the high endemicity of the countries of origin. The molecular characteristics of HBV infection in immigrants reflect those of the geographical areas of origin: HBV genotype A and D predominate in immigrants from Eastern Europe, B and C in those from Asia and genotype E in those from Africa. The literature data on the clinical course and treatment of HBs Agpositive immigrants are scanty. The management of HBV infection in immigrant populations is difficult and requires expert personnel and dedicated structures for their assistance. The social services, voluntary operators and cultural mediators are essential to achieve optimized psychological and clinical intervention. | Nicola Coppola Loredana Alessio Mariantonietta Pisaturo Margherita Macera Caterina Sagnelli Rosa Zampino Evangelista Sagnelli | 2015 | World Journal of Hepatology2015，7，30： | 4 |
| 16 | The next detectors for gravitational wave astronomy显示文摘This paper focuses on the next detectors for gravitational wave astronomy which will be required after the current ground based detectors have completed their initial observations, and probably achieved the first direct detection of gravitational waves. The next detectors will need to have greater sensitivity, while also enabling the world array of detectors to have improved angular resolution to allow localisation of signal sources. Sect. 1 of this paper begins by reviewing proposals for the next ground based detectors,and presents an analysis of the sensitivity of an 8 km armlength detector, which is proposed as a safe and cost-effective means to attain a 4-fold improvement in sensitivity. The scientific benefits of creating a pair of such detectors in China and Australia is emphasised. Sect. 2 of this paper discusses the high performance suspension systems for test masses that will be an essential component for future detectors, while sect. 3 discusses solutions to the problem of Newtonian noise which arise from fluctuations in gravity gradient forces acting on test masses. Such gravitational perturbations cannot be shielded, and set limits to low frequency sensitivity unless measured and suppressed. Sects. 4 and 5 address critical operational technologies that will be ongoing issues in future detectors. Sect. 4 addresses the design of thermal compensation systems needed in all high optical power interferometers operating at room temperature. Parametric instability control is addressed in sect. 5. Only recently proven to occur in Advanced LIGO, parametric instability phenomenon brings both risks and opportunities for future detectors. The path to future enhancements of detectors will come from quantum measurement technologies. Sect. 6 focuses on the use of optomechanical devices for obtaining enhanced sensitivity, while sect. 7 reviews a range of quantum measurement options. | BLAIR David JU Li ZHAO ChunNong WEN LinQing MIAO HaiXing CAI RongGen GAO JiangRui LIN XueChun LIU Dong WU Ling-An ZHU ZongHong HAMMOND Giles PAIK Ho Jung FAFONE Viviana ROCCHI Alessio BLAIR Carl MA YiQiu QIN JiaYi PAGE Michael | 2015 | Science China(Physics,Mechanics & Astronomy)2015，58，12： | 3 |
| 17 | Pelvic radiation disease:Updates on treatment options显示文摘Pelvic cancers are among the most frequently diagnosed neoplasms and radiotherapy represents one of the main treatment options. The irradiation field usually encompasses healthy intestinal tissue,especially of distal large bowel,thus inducing gastrointestinal(GI) radiation-induced toxicity. Indeed,up to half of radiationtreated patients say that their quality of life is affected by GI symptoms(e.g.,rectal bleeding,diarrhoea). The constellation of GI symptoms- from transient to longterm,from mild to very severe- experienced by patients who underwent radiation treatment for a pelvic tumor have been comprised in the definition of pelvic radiation disease(PRD). A correct and evidence-based therapeutic approach of patients experiencing GI radiation-induced toxicity is mandatory. Therapeutic non-surgical strategies for PRD can be summarized in two broad categories,i.e.,medical and endoscopic. Of note,most of the studies have investigated the management of radiation-induced rectal bleeding. Patients with clinically significant bleeding(i.e.,causing chronic anemia) should firstly be considered for medical management(i.e.,sucralfate enemas,metronidazole and hyperbaric oxygen); in case of failure,endoscopic treatment should be implemented. This latter should be considered the first choice in case of acute,transfusion requiring,bleeding. More well-performed,high quality studies should be performed,especially the role of medical treatments should be better investigated as well as the comparative studies between endoscopic and hyperbaric oxygen treatments. | Leonardo Frazzoni Marina La Marca Alessandra Guido Alessio Giuseppe Morganti Franco Bazzoli Lorenzo Fuccio | 2015 | World Journal of Clinical Oncology2015，6，6： | 3 |
| 18 | Protective effect of resveratrol against cadmium-induced toxicity on ovine oocyte in vitro maturation and fertilization显示文摘Background:Heavy metal cadmium(Cd)is a widespread environmental contaminant with a potential toxicity that might negatively affect female reproduction and fertility.It has been reported that Cd exposure impaired the quality of oocytes and led to a defective maturation and fertilization,through oxidative stress induction.Resveratrol(Res)is a natural polyphenol with strong antioxidant properties that exhibited protective role in preventing oocyte redox homeostasis disruption and quality decline.Here,we explored whether the addition of Res to in vitro maturation(IVM)medium might act as a protection against Cd-induced toxicity on ovine oocyte maturation and fertilization.Firstly,we evaluated the effect of supplementing IVM medium with two different Res concentrations(1and 2μmol/L)on nuclear maturation and fertilization of oocytes matured under CdCl2(2μmol/L)exposure.Therefore,the concentration of 1μmol/L Res was selected to analyse the effects of this compound on intracellular ROS levels,mitochondrial(mt)distribution and activity,chromatin configuration,cytoskeleton morphology,cortical granules(CGs)distribution and mRNA expression of genes associated with cellular response to oxidative stress(i.e.SIRT1,SOD 1,GPX1,GSR,CAT)in Cd-exposed in vitro matured oocytes.Results:We found that 1μmol/L Res restored the reduced oocyte meiotic competence induced by Cd exposure as well as,Res sustained oocyte ability to be normally fertilized and decreased polyspermic fertilization at both tested concentrations.Moreover,we demonstrated that 1μmol/L Res mitigated Cd-induced alterations of oocyte cytoplasmic maturation by reducing reactive oxygen species(ROS)accumulation,preventing mt dysfunction,maintaining the correct meiotic spindle and cortical F-actin assembly and the normal cortical granule distribution as well as up-regulating SIRT1,SOD1 and GPX1 genes.Conclusions:Taken together,our findings highlighted the beneficial influence exerted by Res in preventing Cdinduced disturbance of nuclear and cytoplasmic maturation and subsequent fertilization in ovine oocytes.Res treatment may help to establish defence strategies counteracting Cd-induced toxicity on the female gamete. | Anna Rita Piras Federica Ariu Alessio Maltana Giovanni Giuseppe Leoni Nicola Antonio Martino Antonella Mastrorocco Maria Elena Dell’Aquila Luisa Bogliolo | 2023 | Journal of Animal Science and Biotechnology2023，14，1： | 3 |
| 19 | Transcranial Direct Current Stimulation in ADHD:A Systematic Review of Efficacy,Safety,and Protocol-induced Electrical Field Modeling Results显示文摘Transcranial direct current stimulation(tDCS)is a promising method for altering cortical excitability with clinical implications.It has been increasingly used in neurodevelopmental disorders,especially attention-deficit hyperactivity disorder(ADHD),but its efficacy(based on effect size calculations),safety,and stimulation parameters have not been systematically examined.In this systematic review,we aimed to(1)explore the effectiveness of tDCS on the clinical symptoms and neuropsychological deficits of ADHD patients,(2)evaluate the safety of tDCS application,especially in children with ADHD,(3)model the electrical field intensity in the target regions based on the commonly-applied and effective versus less-effective protocols,and(4)discuss and propose advanced tDCS parameters.Using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses approach,a literature search identified 14 empirical experiments investigating tDCS effects in ADHD.Partial improving effects of tDCS on cognitive deficits(response inhibition,working memory,attention,and cognitive flexibility)or clinical symptoms(e.g.,impulsivity and inattention)are reported in10 studies.No serious adverse effects are reported in 747 sessions of tDCS.The left and right dorsolateral prefrontal cortex are the regions most often targeted,and anodal tDCS the protocol most often applied.An intensity of 2 mA induced stronger electrical fields than 1 mA in adults with ADHD and was associated with significant behavioral changes.In ADHD children,however,the electrical field induced by 1 mA,which is likely larger than the electrical field induced by 1 mA in adults due to the smaller head size of children,was sufficient to result in significant behavioral change.Overall,tDCS seems to be a promising method for improving ADHD deficits.However,the clinical utility of tDCS in ADHD cannot yet be concluded and requires further systematic investigation in larger sample sizes.Cortical regions involved in ADHD pathophysiology,stimulation parameters(e.g.intensity,duration,polarity,and electrode size),and types of symptom/deficit are potential determinants of tDCS efficacy in ADHD.Developmental aspects of tDCS in childhood ADHD should be considered as well. | Mohammad Ali Salehinejad Vahid Nejati Mohsen Mosayebi-Samani Ali Mohammadi Miles Wischnewski Min-Fang Kuo Alessio Avenanti Carmelo M・Vicario Michael A.Nitsche | 2020 | Neuroscience Bulletin2020，36，10： | 3 |
| 20 | Optimization of transdisciplinary management of elderly with femur proximal extremity fracture:A patient-tailored plan from orthopaedics to rehabilitation显示文摘Fractures of femur proximal extremity(FFPE)are the most common fragility fractures requiring hospitalization,with a high risk of mortality,low independence in the activities of daily living and severe consequences on healthrelated quality of life.Timing for surgery has a key role in the management of elderly patients with FFPE as recommended by the Australian and New Zealand guidelines and the National Institute for Health and Care Excellence guidelines.Early surgery(within 48 h from hospital admission)allows significant benefits in terms of lower rates of postoperative complications and risk of death and can provide better functional outcomes.Therefore,time for surgery could be considered as a comorbidity marker.The choice between conservative or surgical approach surprisingly seems to be still not strongly supported by available literature,but it seems that both 30 d and 1 year risk of mortality is higher with the conservative treatment rather than with surgery.In light of these considerations,the optimization of FFPE management care is mandatory to improve functional outcomes and to reduce sanitary costs.Albeit it is widely accepted that transdisciplinary approach to patients suffering from FFPE is mandatory to optimize both short-term and long-term outcomes,the feasibility of a comprehensive approach in clinical practice is still a challenge.In particular,the large variability of figures involved could be considered both a resource and an additional disadvantage taking into account the difficulty to coordinate multidisciplinary approach covering care in all settings.Therefore,the aim of the present article was to summarize current evidence supporting transdisciplinary management of patients with FFPE,highlighting the benefits,feasibility and limitations of this approach. | Alessandro de Sire Marco Invernizzi Alessio Baricich Lorenzo Lippi Antonio Ammendolia Federico Alberto Grassi Massimiliano Leigheb | 2021 | World Journal of Orthopedics2021，12，7： | 3 |
