| 1 | Abiotic and Biotic Stresses and Changes in the Lignin Content and Composition in Plants显示文摘Lignin is a polymer of phenylpropanoid compounds formed through a complex biosynthesis route,represented by a metabolic grid for which most of the genes involved have been sequenced in several plants,mainly in the model-plants Arabidopsis thaliana and Populus.Plants are exposed to different stresses,which may change lignin content and composition.In many cases,particularly for plant-microbe interactions,this has been suggested as defence responses of plants to the stress.Thus,understanding how a stressor modulates expression of the genes related with lignin biosynthesis may allow us to develop study-models to increase our knowledge on the metabolic control of lignin deposition in the cell wall.This review focuses on recent literature reporting on the main types of abiotic and biotic stresses that alter the biosynthesis of lignin in plants. | Jullyana Cristina Magalhaes Silva Moura Cesar Augusto Valencise Bonine Juliana de Oliveira Fernandes Viana Marcelo Carnier Dornelas Paulo Mazzafera | 2010 | Journal of Integrative Plant Biology2010，52，4： | 45 |
| 2 | Regulation of multidrug resistance by microRNAs in anti-cancer therapy显示文摘Multidrug resistance(MDR) remains a major clinical obstacle to successful cancer treatment.Although diverse mechanisms of MDR have been well elucidated, such as dysregulation of drugs transporters, defects of apoptosis and autophagy machinery, alterations of drug metabolism and drug targets, disrupti on of redox homeostasis, the exact mechanisms of MDR in a specific cancer patient and the cross-talk among these different mechanisms and how they are regulated are poorly understood.Micro RNAs(mi RNAs) are a new class of small noncoding RNAs that could control the global activity of the cell by post-transcriptionally regulating a large variety of target genes and proteins expression.Accumulating evidence shows that mi RNAs play a key regulatory role in MDR through modulating various drug resistant mechanisms mentioned above, thereby holding much promise for developing novel and more effective individualized therapies for cancer treatment. This review summarizes the various MDR mechanisms and mainly focuses on the role of mi RNAs in regulating MDR in cancer treatment. | Xin An Cesar Sarmiento Tao Tan Hua Zhu | 2017 | Acta Pharmaceutica Sinica B2017，7，1： | 29 |
| 3 | 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 |
| 4 | Follow-up of intestinal metaplasia in the stomach: When, how and why显示文摘Gastric cancer remains the second most frequent cause of cancer-related mortality in the world. Screening programs in some Asian countries are impractical in the majority of other countries worldwide. Therefore, follow-up of precancerous lesions is advisable for secondary gastric cancer prevention. Intestinal metaplasia (IM) is recognized as a precancerous lesion for gastric cancer, increasing the risk by 6-fold. IM is highly prevalent in the general population, being detected in nearly 1 of every 4 patients undergoing upper endoscopy. The IM prevalence rate is significantly higher in patients with Helicobacter pylori (H. pylori) infection, in first-degree relatives of gastric cancer patients, in smokers and it increases with patient age. IM is the 'breaking point' in the gastric carcinogenesis cascade and does not appear to regress following H. pylori eradication, although the cure of infection may slow its progression. Gastric cancer risk is higher in patients with incomplete-type IM, in those with both antral and gastric body involvement, and the risk significantly increases with IM extension over 20% of the gastric mucosa. Scheduled endoscopic control could be cost-effective in IM patients, depending on the yearly incidence of gastric cancer in IM patients, the stage of gastric cancer at diagnosis discovered at surveillance, and the cost of endoscopy. As a pragmatic behavior, yearly endoscopic control would appear justified in all IM patients with at least one of these conditions: (1) IM extension > 20%; (2) the presence of incomplete type IM; (3) first-degree relative of gastric cancer patients; and (4) smokers. In the remaining IM patients, a less intensive (2-3 years) could be proposed. | Angelo Zullo Cesare Hassan Adriana Romiti Michela Giusto Carmine Guerriero Roberto Lorenzetti Salvatore MA Campo Silverio Tomao | 2012 | World Journal of Gastrointestinal Oncology2012，4，3： | 25 |
| 5 | Antidiabetic therapy and increased risk of hepatocellular carcinoma in chronic liver disease显示文摘AIM:To explore the association between hepatocellular carcinoma(HCC) and type 2 diabetes mellitus, describe the temporal relations between the onset of diabetes and the development of HCC and evaluate the possible effects of antidiabetic therapy on HCC risk.METHODS:We recruited 465 HCC patients, 618 with cirrhosis and 490 control subjects.We evaluated the odds ratio(OR) for HCC by univariate and multivariate analysis.Moreover, OR for HCC in diabetic subjects treated with insulin or sulphanylureas and with metformin were calculated.RESULTS:The prevalence of diabetes mellitus was 31.2% in HCC, 23.3% in cirrhotic patients and 12.7% in the Control group.By univariate and multivariate analysis, the OR for HCC in diabetic patients were respectively 3.12(CI 2.2-4.4, P < 0.001) and 2.2(CI 1.2-4.4, P = 0.01).In 84.9% of cases, type 2 diabetes mellitus was present before the diagnosis of HCC.Moreover, we report an OR for HCC of 2.99(CI 1.34-6.65, P = 0.007) in diabetic patients treated with insulin or sulphanylureas, and an OR of 0.33(CI 0.1-0.7, P = 0.006) in diabetic patients treated with metformin.CONCLUSION:Our study confi rms that type 2 diabetes mellitus is an independent risk factor for HCC and pre-exists in the majority of HCC patients.Moreover, in male patients with type 2 diabetes mellitus, our data shows a direct association of HCC with insulin and sulphanylureas treatment and an inverse relationship with metformin therapy. | Valter Donadon Massimiliano Balbi Michela Ghersetti Silvia Grazioli Antonio Perciaccante Giovanni Della Valentina Rita Gardenal Maria Dal Mas Pietro Casarin Giorgio Zanette Cesare Miranda | 2009 | World Journal of Gastroenterology2009，15，20： | 23 |
| 6 | Gastric low-grade mucosal-associated lymphoid tissue-lymphoma: Helicobacter pylori and beyond显示文摘The stomach is the most frequently involved site for extranodal lymphomas,accounting for nearly two-thirds of all gastrointestinal cases.It is widely accepted that gastric B-cell,low-grade mucosal-associated lymphoid tissue(MALT)-lymphoma is caused by Helicobacter pylori(H.pylori)infection.MALT-lymphomas may engender different clinical and endoscopic patterns.Often,diagnosis is confirmed in patients with only vague dyspeptic symptoms and without macroscopic lesions on gastric mucosa.H.pylori eradication leads to lymphoma remission in a large number of patients when treatment occurs at an early stage(Ⅰ-Ⅱ1).Neoplasia confined to the submucosa,localized in the antral region of the stomach,and without API2-MALT1 translocation,shows a high probability of remission following H.pylori eradication.When both bacterial infection and lymphoma recur,further eradication therapy is generally effective.Radiotherapy,chemotherapy and,in selected cases,surgery are the available therapeutic options with a high success rate for those patients who fail to achieve remission,while data on immunotherapy with monoclonal antibodies (rituximab)are still scarce.The 5-year survival rate is higher than 90%,but careful,long-term follow-up is required in these patients since lymphoma recurrence has been reported in some cases. | Angelo Zullo Cesare Hassan Francesca Cristofari Francesco Perri Sergio Morini | 2010 | World Journal of Gastrointestinal Oncology2010，2，4： | 21 |
| 7 | Radiofrequency ablation for treatment of hypersplenism: A feasible therapeutic option显示文摘We present a case of a patient with hypersplenism secondary to portal hypertension due to hepato-splenic schistosomiasis, which was accompanied by severe and refractory thrombocytopenia. We performed spleen ablation and measured the total spleen and ablated volumes with contrast-enhanced computed tomography and volumetry. No major complications occurred, thrombocytopenia was resolved, and platelet levels remained stable, which allowed for early treatment of the patient's underlying disease. Previous work has shown that splenic radiofrequency ablation is an attractive alternative treatment for hypersplenism induced by liver cirrhosis. We aimed to contribute to the currently sparse literature evaluating the role of radiofrequency ablation(RFA) in the management of hypersplenism. We conclude that splenic RFA appears to be a viable and promising option for the treatment of hypersplenism. | Guilherme Lopes P Martins Joao Paulo G Bernardes Marcello S Rovella Raphael G Andrade Publio Cesar C Viana Paulo Herman Giovanni Guido Cerri Marcos Roberto Menezes | 2015 | World Journal of Gastroenterology2015，21，20： | 17 |
| 8 | Diagnosis of pancreatic tumors by endoscopic ultrasound-guided fine-needle aspiration显示文摘AIM: To evaluate the diagnostic accuracy of endoscopic ultrasound-guided fi ne-needle aspiration (EUS-FNA) for pancreatic solid tumors larger or smaller than 3 cm, and cystic lesions. METHODS: From January/1997 to December/2006, 611 patients with pancreatic tumors were subjected to EUS-FNA. The fi nal diagnosis was obtained either by surgery (356 cases) or after a mean clinical follow-up of 11.8 mo in the remaining patients. RESULTS: There were 405 solid tumors, 189 cystic lesions and 17 mixed. Pancreatic specimens for cytological assessment were successfully obtained by EUS-FNA in 595 (97.4/) cases. There were 352 (57.6/) malignancies and 259 (42.4/) benign tumors. Among the malignancies, pancreatic adenocarcinomas accounted for 67/ of the lesions. Overall, the sensitivity, specifi city, positive and negative predictive values, and accuracy of EUS-FNA were, respectively, 78.4/, 99.2/, 99.3/, 77.2/ and 87.2/. Specif ically for solid tumors, the same parameters for neoplasms larger and smaller than 3 cm were, respectively, 78.8/ vs 82.4/, 100/ vs 98.4/, 100/ vs 99/, 54.8/ vs 74.1/ and 83.1/ vs 87.8/. For cystic lesions, the values were, respectively, 72.2/, 99.3/, 97.5/, 91/ and 92.2/. CONCLUSION: EUS-FNA can be used to sample pancreatic tumors in most patients. Even though the negative predictive value is inadequate for large solid tumors, the results are rather good for small solid tumors, especially concerning the sensitivity, negative predictive value and diagnostic accuracy. Among all pancreatic lesions, EUS-FNA for cystic lesions canreveal the best negative predictive value and diagnostic accuracy, both higher than 90/. | José Celso Ardengh César Vivian Lopes Luiz Felipe Pereira de Lima Juliano Rodrigues de Oliveira Filadélfi o Venco Giulio Cesare Santo José Luiz Pimenta Módena | 2007 | World Journal of Gastroenterology2007，13，22： | 17 |
| 9 | 1895-2016年全球海运网络中的海峡两岸港口运输联系变化显示文摘台湾地区与中国大陆隔海相望,海上运输是两岸间货物往来的最主要方式。受国际政治和贸易模式的影响,从19世纪中后期以来,两岸港口运输联系变化剧烈。利用劳合社(Lloyd's)1895-2016年两岸港口间航线的O-D数据,从国家层面和全球层面研究海峡两岸港口运输联系的变化。主要结论为:(1)近代开埠至割让给日本之前,台湾地区与大陆的海运联系紧密,厦门港是台湾地区最重要的中转港;日据之后,台湾地区成为日本的原料来源地和商品销售地,台湾地区—日本—中国大陆形成三角运输联系;两岸对峙后,两岸港口运输联系切断,台湾地区—美国—日本形成三角贸易网络;1979年后,香港港成为两岸运输联系的最重要中转港,两岸直航后,台湾地区与大陆间的港口运输联系在广度和深度上不断拓展。(2)台湾地区区位优势明显,但由于是海岛,陆向腹地狭小,因此充分利用区位优势和地缘优势,把区域经济增长中心作为自身的海向腹地,以形成紧密的海上运输联系是台湾地区经济持续发展的关键。改善与中国大陆之间的关系、分享中国大陆发展的机遇、推动海峡两岸的港口运输联系是台湾地区的'天时'与'人和'。 | 王列辉 林羽珊 Cesar DUCRUET | 2018 | 地理学报2018，73，12： | 16 |
| 10 | Yb-doped large-pitch fibres: effective single-mode operation based on higher-order mode delocalisation显示文摘Rare earth-doped fibres are a diode-pumped,solid-state laser architecture that is highly scalable in average power.The performance of pulsed fibre laser systems is restricted due to nonlinear effects.Hence,fibre designs that allow for very large mode areas at high average powers with diffraction-limited beam quality are of enormous interest.Ytterbium-doped,rod-type,large-pitch fibres(LPF)enable extreme fibre dimensions,i.e.,effective single-mode fibres with mode sizes exceeding 100 times the wavelength of the guided radiation,by exploiting the novel concept of delocalisation of higher-order transverse modes.The non-resonant nature of the operating principle makes LPF suitable for high power extraction.This design allows for an unparalleled level of performance in pulsed fibre lasers. | Jens Limpert Fabian Stutzki Florian Jansen Hans-Jurgen Otto Tino Eidam Cesar Jauregui Andreas Tunnermann | 2012 | Light(Science & Applications)2012，1，1： | 16 |

| 12 | Impact of a single bout of high-intensity interval exercise and short-term interval training on interleukin-6, FNDC5, and METRNL mRNA expression in human skeletal muscle显示文摘Background: Exercise promotes numerous phenotypic adaptations in skeletal muscle that contribute to improved function and metabolic capacity. An emerging body of evidence suggests that skeletal muscle also releases a myriad of factors during exercise, termed 'myokines'. The purpose of this study was to examine the effects of high-intensity interval training(HIIT) on the acute regulation of the mRNA expression of several myokines, including the prototypical myokine interleukin-6(IL-6), and recently identified myokines fibronectin type III domain-containing protein 5(FNDC5)(irisin) and meteorin-like protein(METRNL).Methods: Both before and after a 20-day period of twice-daily high-volume HIIT, 9 healthy males(20.5 ± 1.5 years performed a standardized bout of high-intensity interval exercise(HIIE; 5 × 4 min at ~80% pretraining peak power output) with skeletal muscle biopsy samples(vastus lateralis) obtained at rest, immediately following exercise, and at 3 h recovery.Results: Before training, a single bout of HIIE increased IL-6(p < 0.05) and METRNL(p < 0.05) mRNA expression measured at 3 h recovery when compared to rest. Following 20 days of HIIT, IL-6 and FNDC5 mRNA were increased at 3 h recovery from the standardized HIIE bout when compared to rest(both p < 0.05). Resting METRNL and FNDC5 mRNA expression were higher following training(p < 0.05), and there was an overall increase in FNDC5 mRNA post-training(main effect of training, p < 0.05).Conclusion: In human skeletal muscle(1) an acute bout of HIIE can induce upregulation of skeletal muscle IL-6 mRNA both before and after a period of intensified HIIT;(2) Resting and overall FNDC5 mRNA expression is increased by 20 days of HIIT; and(3) METRNL mRNA expression is responsive to both acute HIIE and short-term intense HIIT. Future studies are needed to confirm these findings at the protein and secretion level in humans. | Malcolm Eaton Cesare Granata Julianne Barry Adeel Safdar David Bishop Jonathan P.Little | 2018 | Journal of Sport and Health Science2018，7，2： | 15 |
| 13 | Data-based Fault Tolerant Control for Affine Nonlinear Systems Through Particle Swarm Optimized Neural Networks显示文摘In this paper, a data-based fault tolerant control(FTC) scheme is investigated for unknown continuous-time(CT)affine nonlinear systems with actuator faults. First, a neural network(NN) identifier based on particle swarm optimization(PSO) is constructed to model the unknown system dynamics. By utilizing the estimated system states, the particle swarm optimized critic neural network(PSOCNN) is employed to solve the Hamilton-Jacobi-Bellman equation(HJBE) more efficiently.Then, a data-based FTC scheme, which consists of the NN identifier and the fault compensator, is proposed to achieve actuator fault tolerance. The stability of the closed-loop system under actuator faults is guaranteed by the Lyapunov stability theorem. Finally, simulations are provided to demonstrate the effectiveness of the developed method. | Haowei Lin Bo Zhao Derong Liu Cesare Alippi | 2020 | IEEE/CAA Journal of Automatica Sinica2020，7，4： | 13 |
| 14 | Modified activated carbon with interconnected fibrils of iron-oxyhydroxides using Mn^(2+) as morphology regulator, for a superior arsenic removal from water显示文摘The arsenic removal efficiency of iron-modified activated carbons depends greatly on the number of available iron oxide surface sites, which are given by the surface area of the anchored particles. In this sense, aiming the generation of an adsorbent with superior arsenic adsorption capacity, we developed a protocol to anchor interconnected fibrils of iron oxyhydroxides, using Mn^(2+) as a morphology regulator. The protocol was based on a microwave-assisted hydrothermal method, using bituminous based activated carbon and both Fe^(2+) and Mn^(2+) ions in the hydrolysis solution. The elemental analysis of modified carbons revealed that Mn does not anchor to the carbon. However, when Mn is included in the hydrolysis solution, the iron content in the activated carbon increased up to 3.5 wt%,without considerable decreasing the adsorbent surface area. Under specific hydrothermal conditions, the Mn^(2+) promoted the formation of iron oxide nanoparticles shaped as interconnected fibrils. This material showed a superior arsenic adsorption capacity in comparison to similar iron modified activated carbons(5 mg As/g carbon, at 2 mg As/L),attributed to the increase in quantity and availability of active sites located on the novel interconnected fibrils of iron oxyhydroxides nanostructures. | Cesar Nieto-Delgado Joel Gutiérrez-Martínez J.Rene Rangel-Méndez | 2019 | Journal of Environmental Sciences2019，31，2： | 12 |
| 15 | Hepatoprotective effect of silymarin显示文摘The use of medicinal plants in treating illnesses has been reported since ancestral times.In the case of hepatic diseases,several species such as Silybum marianum,Phyllanthus niruri,and Panus giganteus(Berk.)have been shown to ameliorate hepatic lesions.Silymarin is a natural compound derived from the species Silybum marianum,which is commonly known as Milk thistle.This plant contains at least seven flavoligands and the flavonoid taxifolin.The hepatoprotective and antioxidant activity of silymarin is caused by its ability to inhibit the free radicals that are produced from the metabolism of toxic substances such as ethanol,acetaminophen,and carbon tetrachloride.The generation of free radicals is known to damage cellular membranes and cause lipoperoxidation.Silymarin enhances hepatic glutathione and may contribute to the antioxidant defense of the liver.It has also been shown that silymarin increases protein synthesis in hepatocytes by stimulating RNA polymerase I activity.A previous study on humans reported that silymarin treatment caused a slight increase in the survival of patients with cirrhotic alcoholism compared with untreated controls. | Nancy Vargas-Mendoza Eduardo Madrigal-Santillán ngel Morales-González Jaime Esquivel-Soto Cesar Esquivel-Chirino Manuel García-Luna y González-Rubio Juan A Gayosso-de-Lucio José A Morales-González | 2014 | World Journal of Hepatology2014，6，3： | 12 |
| 16 | Endoscopic resection of superficial gastrointestinal tumors显示文摘Therapeutic endoscopy plays a major role in the management of gastrointestinal (GI) neoplasia. Its indications can be generalized into four broad categories; to remove or obliterate neoplastic lesion, to palliate malignant obstruction, or to treat bleeding. Only endoscopic resection allows complete histological staging of the cancer, which is critical as it allows stratification and refinement for further treatment. Although other endoscopic techniques, such as ablation therapy, may also cure early GI cancer, they can not provide a definitive pathological specimen. Early stage lesions reveal low frequency of lymph node metastasis which allows for less invasive treatments and thereby improving the quality of life when compared to surgery. Endoscopic mucosal resection (EMR) and endoscopic submucosal dissection (ESD) are now accepted worldwide as treatment modalities for early cancers of the GI tract. | Giovannini Marc Cesar Vivian Lopes | 2008 | World Journal of Gastroenterology2008，14，29： | 12 |
| 17 | Mechanisms of Helicobacter pylori antibiotic resistance:An updated appraisal显示文摘Helicobacter pylori(H. pylori) antibiotic resistance is the main factor affecting the efficacy of the current eradicating therapies. The aim of this editorial is to report on the recent information about the mechanisms accounting for the resistance to the different antibiotics currently utilized in H. pylori eradicating treatments. Different mechanisms of resistance to clarithromycin,metronidazole,quinolones,amoxicillin and tetracycline are accurately detailed(point mutations,redox intracellular potential,pump efflux systems,membrane permeability) on the basis of the most recent data available from the literature. The next hope for the future is that by improving the knowledge of resistance mechanisms,the elaboration of rational and efficacious associations for the treatment of the infection will be possible. Another auspicious progress might be the possibility of a cheap,feasible and reliable laboratory test to predict the outcome of a therapeutic scheme. | Vincenzo De Francesco Angelo Zullo Cesare Hassan Floriana Giorgio Rosa Rosania Enzo Ierardi | 2011 | World Journal of Gastrointestinal Pathophysiology2011，2，3： | 10 |
| 18 | Neuroprotective effects of human bone marrow mesenchymal stem cells against cerebral ischemia are mediated in part by an anti-apoptotic mechanism显示文摘Transplantation of human bone marrow mesenchymal stem cells(hMSCs) stands as a potent stroke therapy, but its exact mechanism remains unknown. This study investigated the anti-apoptotic mechanisms by which hMSCs exert neuroprotective effects on cerebral ischemia. Primary mixed cultures of rat neurons and astrocytes were cultured and exposed to oxygen-glucose deprivation. A two-hour period of 'reperfusion' in standard medium and normoxic conditions was allowed and immediately followed by hMSCs and/or Bcl-2 antibody treatment. Cell viability of primary rat neurons and astrocytes was determined by 3-(4,5-dimethylthianol-2-yl)-2,5 diphenyl tetrazolium bromide and trypan blue exclusion methods. hMSC survival and differentiation were characterized by immunocytochemistry, while the concentration of Bcl-2 in the supernatant was measured by enzyme-linked immunosorbent assay to reveal the secretory anti-apoptotic function of hMSCs. Cultured hMSCs expressed embryonic-like stem cell phenotypic markers CXCR4, Oct4, SSEA4, and Nanog, as well as immature neural phenotypic marker Nestin. Primary rat neurons and astrocytes were protected from oxygen-glucose deprivation by hMSCs, which was antagonized by the Bcl-2 antibody. However, Bcl-2 levels in the supernatants did not differ between hMSCand non-treated cells exposed to oxygen-glucose deprivation. Neuroprotective effects of hMSCs against cerebral ischemia were partially mediated by the anti-apoptotic mechanisms. However, further studies are warranted to fully elucidate this pathway. | Yuyang Zhang Seongjin Yu Julian P.Tuazon Jea-Young Lee Sydney Corey Lauren Kvederis Chase Kingsbury Yuji Kaneko Cesar V.Borlongan | 2019 | Neural Regeneration Research2019，14，4： | 9 |

| 20 | Managing reservoir sedimentation by venting turbidity currents:A review显示文摘Reservoir sedimentation is an issue that dam operators are increasingly facing as dams are aging.Not only does it reduce a reservoir's capacity but it also affects its outlet structures such as bottom outlets and powerhouse intakes.Sedimentation may also impoverish downstream ecosystems.For these reasons,several strategies for sediment management are being investigated and applied worldwide.Among these methods,venting of turbidity currents reaching the dam can be very beneficial and economical.This measure helps in preserving a certain continuity of sediment transport in rivers obstructed by dams.However,several practical but also theoretical challenges hamper this technique,rendering its use less common and its aspects relatively unknown.The present paper aims to gather the actual state-of-the-art concerning turbidity currents venting and to present an outlook for future development and research in this field. | Sabine Chamoun Giovanni De Cesare Anton J.Schleiss | 2016 | International Journal of Sediment Research2016，31，3： | 9 |
