1Esophageal motility abnormalities in gastroesophageal reflux disease显示文摘Esophageal motility abnormalities are among the main factors implicated in the pathogenesis of gastroesophageal reflux disease. The recent introduction in clinical and research practice of novel esophageal testing has markedly improved our understanding of the mechanisms contributing to the development of gastroesophageal reflux disease, allowing a better management of patients with this disorder. In this context, the present article intends to provide an overview of the current literature about esophageal motility dysfunctions in patients with gastroesophageal reflux disease. Esophageal manometry, by recording intraluminal pressure, represents the gold standard to diagnose esophagealmotility abnormalities. In particular, using novel techniques, such as high resolution manometry with or without concurrent intraluminal impedance monitoring, transient lower esophageal sphincter (LES) relaxations, hypotensive LES, ineffective esophageal peristalsis and bolus transit abnormalities have been better defined and strongly implicated in gastroesophageal reflux disease development. Overall, recent findings suggest that esophageal motility abnormalities are increasingly prevalent with increasing severity of reflux disease, from nonerosive reflux disease to erosive reflux disease and Barrett's esophagus. Characterizing esophageal dysmotility among different subgroups of patients with reflux disease may represent a fundamental approach to properly diagnose these patients and, thus, to set up the best therapeutic management. Currently, surgery represents the only reliable way to restore the esophagogastric junction integrity and to reduce transient LES relaxations that are considered to be the predominant mechanism by which gastric contents can enter the esophagus. On that ground, more in depth future studies assessing the pathogenetic role of dysmotility in patients with reflux disease are warranted.Irene Martinucci Nicola de Bortoli Maria Giacchino Giorgia Bodini Elisa Marabotto Santino Marchi Vincenzo Savarino Edoardo Savarino 2014World Journal of Gastrointestinal Pharmacology and Therapeutics2014,5,2:24
2Narrow-band imaging with magnifying endoscopy is accurate for detecting gastric intestinal metaplasia显示文摘AIM:To investigate the predictive value of narrowband imaging with magnifying endoscopy (NBI-ME) for identifying gastric intestinal metaplasia (GIM) in unselected patients. METHODS:We prospectively evaluated consecutive patients undergoing upper endoscopy for various indications, such as epigastric discomfort/pain, anaemia, gastro-oesophageal reflux disease, suspicion of peptic ulcer disease, or chronic liver diseases. Patients underwent NBI-ME, which was performed by three blinded, experienced endoscopists. In addition, five biopsies (2 antrum, 1 angulus, and 2 corpus) were taken and examined by two pathologists unaware of the endoscopic findings to determine the presence or absence of GIM. The correlation between light blue crest (LBC) appearance and histology was measured. Moreover, we quantified the degree of LBC appearance as less than 20% (+), 20%-80% (++) and more than 80% (+++) of an image field, and the semiquantitative evaluation of LBC appearance was correlated with IM percentage from the histological findings. RESULTS:We enrolled 100 (58 F/42 M) patients who were mainly referred for gastro-esophageal reflux disease/dyspepsia (46%), cancer screening/anaemia (34%), chronic liver disease (9%), and suspected celiac disease (6%); the remaining patients were referred for other indications. The prevalence of Helicobacter pylori (H. pylori ) infection detected from the biopsies was 31%, while 67% of the patients used proton pump inhibitors. LBCs were found in the antrum of 33 patients (33%); 20 of the cases were classified as LBC+, 9 as LBC++, and 4 as LBC+++. LBCs were found in the gastric body of 6 patients (6%), with 5 of them also having LBCs in the antrum. The correlation between the appearance of LBCs and histological GIM was good, with a sensitivity of 80% (95%CI:67-92), a specificity of 96% (95%CI:93-99), a positive predictive value of 84% (95%CI:73-96), a negative predictive value of 95% (95%CI:92-98), and an accuracy of 93% (95%CI:90-97). The NBI-ME examination overlooked GIM in 8 cases, but the GIM was less than 5% in 7 of the cases. Moreover, in the 6 false positive cases, the histological examination showed the presence of reactive gastropathy (4 cases) or H. pylori active chronic gastritis (2 cases). The semiquantitative correlation between the rate of LBC appearance and the percentage of GIM was 79% (P < 0.01). CONCLUSION:NBI-ME achieved good sensitivity and specificity in recognising GIM in an unselected population. In routine clinical practice, this technique can reliably target gastric biopsies.Edoardo Savarino Marina Corbo Pietro Dulbecco Lorenzo Gemignani Elisa Giambruno Luca Mastracci Federica Grillo Vincenzo Savarino 2013World Journal of Gastroenterology2013,19,17:23
3Molecular pathogenesis of bone metastases in breast cancer: Proven and emerging therapeutic targets显示文摘Metastatic occurrence is the principal cause of death in breast cancer patients. The high osteotropism makes breast cancer the most common primary tumor type associated with metastatic bone disease. The peculiar clinical aspects associated with metastases limited to the skeletal system suggest considering these cases as a distinctive subset of metastatic patients with a better prognosis. Because bone is frequently the first metastatic site in disease relapse, it is feasible that the next improvement in therapeutic options for bone metastatic disease could be associated with an improvement of survival expectation and quality of life in breast cancer patients. Study of the molecular basis of bone remodeling and breast cancer osteotropism has allowed identification of several therapeutic candidates involved in formation and progression of bone metastases. These targets are frequently the determinants of positive feedback between the tumor and bone cells whose clinical outcome is osteolytic lesions. In this review, we discuss the physiopathologic features underlying targeted therapeutic strategies aimed at interfering with the aberrant bone remodeling associated with breast cancer metastases.Nadia Rucci Patrizia Sanità Simona Delle Monache Edoardo Alesse Adriano Angelucci 2014World Journal of Clinical Oncology2014,5,3:18
4Thrombus aspiration in acute myocardial infarction:Rationale and indication显示文摘Reperfusion of myocardial tissue is the main goal of primary percutaneous coronary intervention(PPCI) with stent implantation in the treatment of acute ST-segment elevation myocardial infarction(STEMI). Although PPCI has contributed to a dramatic reduction in cardiovascular mortality over three decades, normal myocardial perfusion is not restored in approximately one-third of these patients. Several mechanisms may contribute to myocardial reperfusion failure, in particular distal embolization of the thrombus and plaque fragments. In fact, this is a possible complication during PPCI, resulting in microvascular obstruction and no-reflow phenomenon. The presence of a visible thrombus at the time of PPCI in patients with STEMI is associated with poor procedural and clinical outcomes. Aspiration thrombectomy during PPCI has been proposed to prevent embolization in order to improve these outcomes. In fact, the most recent guidelines suggest the routine use of manual aspiration thrombectomy during PPCI(class Ⅱa) to reduce the risk of distal embolization. Even though numerous international studies have been reported, there are conflicting results on the clinical impact of aspiration thrombectomy during PPCI. In particular, data on long-term clinical outcomes are still inconsistent. In this review, we have carefully analyzed literature data on thrombectomy during PPCI, taking into account the most recent studies and meta-analyses.Gennaro Sardella Rocco Edoardo Stio 2014World Journal of Cardiology2014,6,9:15

6How many cases of laryngopharyngeal reflux suspected by laryngoscopy are gastroesophageal reflux disease-related?显示文摘AIM:To investigate the prevalence of gastroesophageal reflux disease(GERD) in patients with a laryngoscopic diagnosis of laryngopharyngeal reflux(LPR).METHODS:Between May 2011 and October 2011,41 consecutive patients with laryngopharyngeal symptoms(LPS) and laryngoscopic diagnosis of LPR were empirically treated with proton pump inhibitors(PPIs) for at least 8 wk,and the therapeutic outcome was assessed through validated questionnaires(GERD impact scale,GIS;visual analogue scale,VAS).LPR diagnosis was performed by ear,nose and throat specialists using the reflux finding score(RFS) and reflux symptom index(RSI).After a 16-d wash-out from PPIs,all patients underwent an upper endoscopy,stationary esophageal manometry,24-h multichannel intraluminal impedance and pH(MII-pH) esophageal monitoring.A positive correlation between LPR diagnosis and GERD was supposed based on the presence of esophagitis(ERD),pathological acid exposure time(AET) in the absence of esophageal erosions(NERD),and a positive correlation between symptoms and refluxes(hypersensitive esophagus,HE).RESULTS:The male/female ratio was 0.52(14/27),the mean age ± SD was 51.5 ± 12.7 years,and the mean body mass index was 25.7 ± 3.4 kg/m 2.All subjects reported one or more LPS.Twenty-five out of 41 patients also had typical GERD symptoms(heartburn and/or regurgitation).The most frequent laryngoscopic findings were posterior laryngeal hyperemia(38/41),linear indentation in the medial edge of the vocal fold(31/41),vocal fold nodules(6/41) and diffuse infraglottic oedema(25/41).The GIS analysis showed that 10/41 patients reported symptom relief with PPI therapy(P < 0.05);conversely,23/41 did not report any clinical improvement.At the same time,the VAS analysis showed a significant reduction in typical GERD symptoms after PPI therapy(P < 0.001).A significant reduction in LPS symptoms.On the other hand,such result was not recorded for LPS.Esophagitis was detected in 2/41 patients,and ineffective esophageal motility was found in 3/41 patients.The MII-pH analysis showed an abnormal AET in 5/41 patients(2 ERD and 3 NERD);11/41 patients had a normal AET and a positive association between symptoms and refluxes(HE),and 25/41 patients had a normal AET and a negative association between symptoms and refluxes(no GERD patients).It is noteworthy that HE patients had a positive association with typical GERD-related symptoms.Gas refluxes were found more frequently in patients with globus(29.7 ± 3.6) and hoarseness(21.5 ± 7.4) than in patients with heartburn or regurgitation(7.8 ± 6.2).Gas refluxes were positively associated with extraesophageal symptoms(P < 0.05).Overall,no differences were found among the three groups of patients in terms of the frequency of laryngeal signs.The proximal reflux was abnormal in patients with ERD/NERD only.The differences observed by means of MII-pH analysis among the three subgroups of patients(ERD/NERD,HE,no GERD) were not demonstrated with the RSI and RFS.Moreover,only the number of gas refluxes was found to have a significant association with the RFS(P = 0.028 andP = 0.026,nominal and numerical correlation,respectively).CONCLUSION:MII-pH analysis confirmed GERD diagnosis in less than 40% of patients with previous diagnosis of LPR,most likely because of the low specificity of the laryngoscopic findings.Nicola de Bortoli Andrea Nacci Edoardo Savarino Irene Martinucci Massimo Bellini Bruno Fattori Linda Ceccarelli Francesco Costa Maria Gloria Mumolo Angelo Ricchiuti Vincenzo Savarino Stefano Berrettini Santino Marchi 2012World Journal of Gastroenterology2012,18,32:11
7Surveillance for early diagnosis of hepatocellular carcinoma: How best to do it?显示文摘Surveillance for hepatocellular carcinoma(HCC)is considered a standard of care for patients with chronic liver disease who are at risk of developing this malignancy.Several studies have shown that surveillance can improve the prognosis of patients diagnosed with HCC through an increased likelihood of application of curative or effective treatments.Repetition of liver ultrasonography(US)every 6 mo is the recommended surveillance program to detect early HCCs,and a positive US has to entrain a well-defined recall policy based on contrast-enhanced,dynamic radiological imaging or biopsy for the diagnosis of HCC.Although HCC fulfills the accepted criteria regarding cost-effective cancer screening and surveillance,the implementation of surveillance in clinical practice is defective and this has a negative impact on the cost-effectiveness of the procedure.Education of both physicians and patients is of paramount importance in order to improve the surveillance application and its benefits in patients at risk of HCC.The promotion of specific educational programs for practitioners,clinicians and patients is instrumental in order to expand the correct use of surveillance in clinical practice and eventually improve HCC prognosis.Edoardo G Giannini Alessandro Cucchetti Virginia Erroi Francesca Garuti Federica Odaldi Franco Trevisani 2013World Journal of Gastroenterology2013,19,47:10
8Comparative study of laparoscopic vs open gastrectomy in gastric cancer management显示文摘AIM:To compare long-term results of gastric cancer patients undergoing laparoscopic and open gastrec-tomy in a single unit.METHODS:From February 2000 to September 2004,all patients with adenocarcinoma of the stomach were assessed to entry in this longitudinal prospective non-randomized trial.Primary endpoint was cancer-related survival and secondary endpoints were overall survival,evaluation of surgical complications and mortality.RESULTS:Fifty-eight patients were enrolled.Forty-seven patients were followed-up(range 11-103,me-dian 38 mo).Four patients were lost at follow up.Twenty-two patients underwent a laparoscopic gastric surgery(LGS)and 25 had a standard open procedure(OGS).No statistical difference was found between the two groups in terms of 5 years cancer-related mortality rate(50% vs 52%,P = 1),and 5 years overall mortal-ity rate(54.5% vs 56%,P = 1).Accordingly,cancer-related and overall survival probability by Kaplan-Meier method showed comparable results(P = 0.81 and P = 0.83,respectively).We found no differences in surgical complications in the 2 groups.There was no conversion to open surgery in this series.CONCLUSION:LGS is as effective as OGS in the man-agement of advanced gastric cancer.However LGS can-not be recommended routinely over OGS for the treat-ment of advanced gastric cancer.Giuseppe S Sica Edoardo Iaculli Livia Biancone Sara Di Carlo Rosa Scaramuzzo Cristina Fiorani Paolo Gentileschi Achille L Gas-pari 2011World Journal of Gastroenterology2011,17,41:9
9Overlap of functional heartburn and gastroesophageal reflux disease with irritable bowel syndrome显示文摘Several studies indicate a significant degree of overlap between irritable bowel syndrome(IBS)and gastroesophageal reflux disease(GERD).Likewise,both functional heartburn(FH)and IBS are functional digestive disorders that may occur in the same patients.However,data establishing a solid link between FH and IBS are lacking,mainly because the clinical definition of FH has undergone substantial changes over the years.The available literature on the overlap between GERD or FH and IBS highlights considerable heterogeneity in terms of the criteria and diagnostic procedures used to assess heartburn and IBS.In particular,several epidemiological studies included patients with concomitant IBS and GERD without any attempt to distinguish FH(as defined by the RomeⅢcriteria)from GERD via pathophysiological investigations.Independent of these critical issues,there is preliminary evidence supporting a significantdegree of FH-IBS overlap.This underscores the need for studies based on updated diagnostic criteria and accurate pathophysiological classifications,particularly to distinguish FH from GERD.This distinction would represent an essential starting point to achieving a better understanding of pathophysiology in the subclasses of patients with GERD and FH and properly assessing the different degrees of overlap between IBS and the subcategories of heartburn.The present review article intends to appraise and critically discuss current evidence supporting a possible concomitance of GERD or FH with IBS in the same patients and to highlight the pathophysiological relationships between these disorders.Nicola de Bortoli Irene Martinucci Massimo Bellini Edoardo Savarino Vincenzo Savarino Corrado Blandizzi Santino Marchi 2013World Journal of Gastroenterology2013,19,35:9

11Single-photon avalanche diode imagers in biophotonics:review and outlook显示文摘Single-photon avalanche diode(SPAD)arrays are solid-state detectors that offer imaging capabilities at the level of individual photons,with unparalleled photon counting and time-resolved performance.This fascinating technology has progressed at a very fast pace in the past 15 years,since its inception in standard CMOS technology in 2003.A host of architectures have been investigated,ranging from simpler implementations,based solely on off-chip data processing,to progressively“smarter”sensors including on-chip,or even pixel level,time-stamping and processing capabilities.As the technology has matured,a range of biophotonics applications have been explored,including(endoscopic)FLIM,(multibeam multiphoton)FLIM-FRET,SPIM-FCS,super-resolution microscopy,time-resolved Raman spectroscopy,NIROT and PET.We will review some representative sensors and their corresponding applications,including the most relevant challenges faced by chip designers and end-users.Finally,we will provide an outlook on the future of this fascinating technology.Claudio Bruschini Harald Homulle Ivan Michel Antolovic Samuel Burri Edoardo Charbon 2019Light(Science & Applications)2019,8,1:8
12A randomized trial of iron depletion in patients with nonalcoholic fatty liver disease and hyperferritinemia显示文摘AIM:To compare iron depletion to lifestyle changes alone in patients with severe nonalcoholic fatty liver disease(NAFLD)and hyperferritinemia,a frequent feature associated with more severe liver damage,despite at least 6 mo of lifestyle changes.METHODS:Eligible subjects had to be 18-75 years old who underwent liver biopsy for ultrasonographically detected liver steatosis and hyperferritinemia,ferritin levels≥250 ng/mL,and NAFLD activity score>1.Iron depletion had to be achieved by removing 350 cc of blood every 10-15 d according to baseline hemoglobin values and venesection tolerance,until ferritin<30 ng/mL and/or transferrin saturation(TS)<25%.Thirty-eight patients were randomized 1:1 to phlebotomy(n=21)or lifestyle changes alone(n=17).The main outcome of the study was improvement in liver damage according to the NAFLD activity score at 2 years,secondary outcomes were improvements in liver enzymes[alanine aminotransferases(ALT),aspartate aminotransferase(AST),and gamma-glutamyl-transferases(GGT)].RESULTS:Phlebotomy was associated with normalization of iron parameters without adverse events.In the21 patients compliant to the study protocol,the rate of histological improvement was higher in iron depleted vs control subjects(8/12,67%vs 2/9,22%,P=0.039).There was a better improvement in steatosis grade in iron depleted vs control patients(P=0.02).In patients followed-up at two years(n=35),ALT,AST,and GGT levels were lower in iron-depleted than in control patients(P<0.05).The prevalence of subjects with improvement in histological damage or,in the absence of liver biopsy,ALT decrease≥20%(associated with histological improvement in biopsied patients)was higher in the phlebotomy than in the control arm(P=0.022).The effect of iron depletion on liver damage improvement as assessed by histology or ALT decrease≥20%was independent of baseline AST/ALT ratio and insulin resistance(P=0.0001).CONCLUSION:Iron depletion by phlebotomy is likely associated with a higher rate of improvement of histological liver damage than lifestyle changes alone in patients with NAFLD and hyperferritinemia,and with amelioration of liver enzymes.Luca Valenti Anna Ludovica Fracanzani Paola Dongiovanni Serena Rovida Raffaela Rametta Erika Fatta Edoardo Alessandro Pulixi Marco Maggioni Silvia Fargion 2014World Journal of Gastroenterology2014,20,11:8
13Esophageal testing: What we have so far显示文摘Gastroesophageal reflux disease(GERD) is a common disorder of the gastrointestinal tract. In the last few decades, new technologies have evolved and have been applied to the functional study of the esophagus, allowing for the improvement of our knowledge of the pathophysiology of GERD. High-resolution manometry(HRM) permits greater understanding of the function of the esophagogastric junction and the risks associated with hiatal hernia. Moreover, HRM has been found to be more reproducible and sensitive than conventional water-perfused manometry to detect the presence of transient lower esophageal sphincter relaxation. Esophageal 24-h p H-metry with or without combined impedance is usually performed in patients with negative endoscopy and reflux symptoms who have a poor response to anti-reflux medical therapy to assess esophageal acid exposure and symptom-reflux correlations. In particular, esophageal 24-h impedance and p H monitoring can detect acid and non-acid reflux events. Endo FLIP is a recent technique poorly applied in clinical practice, although it provides a large amount of information about the esophagogastric junction. In the coming years, laryngopharyngeal symptoms could be evaluated with up and coming non-invasive or minimally invasive techniques, such as pepsin detection in saliva or pharyngeal p H-metry. Future studies are required of these techniques to evaluate their diagnostic accuracy and usefulness, although the available data are promising.Nicola de Bortoli Irene Martinucci Lorenzo Bertani Salvatore Russo Riccardo Franchi Manuele Furnari Salvatore Tolone Giorgia Bodini Valeria Bolognesi Massimo Bellini Vincenzo Savarino Santino Marchi Edoardo Vincenzo Savarino 2016World Journal of Gastrointestinal Pathophysiology2016,7,1:8
14Malignant gastric outlet obstruction:Which is the best therapeutic option?显示文摘Malignant gastric outlet obstruction(MGOO)is a clinical condition characterized by the mechanical obstruction of the pylorus or the duodenum due to tumor compression/infiltration,with consequent reduction or impossibility of an adequate oral intake.MGOO is mainly secondary to advanced pancreatic or gastric cancers,and significantly impacts on patients’survival and quality of life.Patients suffering from this condition often present with intractable vomiting and severe malnutrition,which further compromise therapeutic chances.Currently,palliative strategies are based primarily on surgical gastrojejunostomy and endoscopic enteral stenting with self-expanding metal stents.Several studies have shown that surgical approach has the advantage of a more durable relief of symptoms and the need of fewer re-interventions,at the cost of higher procedure-related risks and longer hospital stay.On the other hand,enteral stenting provides rapid clinical improvement,but have the limit of higher stent dysfunction rate due to tumor ingrowth and a subsequent need of frequent reinterventions.Recently,a third way has come from interventional endoscopic ultrasound,through the development of endoscopic ultrasound-guided gastroenterostomy technique with lumen-apposing metal stent.This new technique may ideally encompass the minimal invasiveness of an endoscopic procedure and the long-lasting effect of the surgical gastrojejunostomy,and brought encouraging results so far,even if prospective comparative trial are still lacking.In this Review,we described technical aspects and clinical outcomes of the above-cited therapeutic approaches,and discussed the open questions about the current management of MGOO.Edoardo Troncone Alessandro Fugazza Annalisa Cappello Giovanna Del Vecchio Blanco Giovanni Monteleone Alessandro Repici Anthony Yuen Bun Teoh Andrea Anderloni 2020World Journal of Gastroenterology2020,26,16:7

16Efficient RT-QuIC seeding activity for α-synuclein in olfactory mucosa samples of patients with Parkinson’s disease and multiple system atrophy显示文摘Background:Parkinson’s disease(PD)is a neurodegenerative disorder whose diagnosis is often challenging because symptoms may overlap with neurodegenerative parkinsonisms.PD is characterized by intraneuronal accumulation of abnormalα-synuclein in brainstem while neurodegenerative parkinsonisms might be associated with accumulation of eitherα-synuclein,as in the case of Multiple System Atrophy(MSA)or tau,as in the case of Corticobasal Degeneration(CBD)and Progressive Supranuclear Palsy(PSP),in other disease-specific brain regions.Definite diagnosis of all these diseases can be formulated only neuropathologically by detection and localization ofα-synuclein or tau aggregates in the brain.Compelling evidence suggests that trace-amount of these proteins can appear in peripheral tissues,including receptor neurons of the olfactory mucosa(OM).Methods:We have set and standardized the experimental conditions to extend the ultrasensitive Real Time Quaking Induced Conversion(RT-QuIC)assay for OM analysis.In particular,by using human recombinantα-synuclein as substrate of reaction,we have assessed the ability of OM collected from patients with clinical diagnoses of PD and MSA to induceα-synuclein aggregation,and compared their seeding ability to that of OM samples collected from patients with clinical diagnoses of CBD and PSP.Results:Our results showed that a significant percentage of MSA and PD samples inducedα-synuclein aggregation with high efficiency,but also few samples of patients with the clinical diagnosis of CBD and PSP caused the same effect.Notably,the final RT-QuIC aggregates obtained from MSA and PD samples owned peculiar biochemical and morphological features potentially enabling their discrimination.Conclusions:Our study provide the proof-of-concept that olfactory mucosa samples collected from patients with PD and MSA possess important seeding activities forα-synuclein.Additional studies are required for(i)estimating sensitivity and specificity of the technique and for(ii)evaluating its application for the diagnosis of PD and neurodegenerative parkinsonisms.RT-QuIC analyses of OM and cerebrospinal fluid(CSF)can be combined with the aim of increasing the overall diagnostic accuracy of these diseases,especially in the early stages.Chiara Maria Giulia De Luca Antonio Emanuele Elia Sara Maria Portaleone Federico Angelo Cazzaniga Martina Rossi Edoardo Bistaffa Elena De Cecco Joanna Narkiewicz Giulia Salzano Olga Carletta Luigi Romito Grazia Devigili Paola Soliveri Pietro Tiraboschi Giuseppe Legname Fabrizio Tagliavini Roberto Eleopra Giorgio Giaccone Fabio Moda 2019Translational Neurodegeneration2019,8,1:5
17Use of chondral fragments for one stage cartilage repair: A systematic review显示文摘AIM: To investigate the state of the art regarding Cartilage Autograft Implantation System(CAIS) or Particulated Juvenile Allograft Cartilage(PJAC).METHODS: The authors searched the English literature regarding CAIS and PJAC. The search strategy was:(particulated cartilage) OR autologous cartilage fragments. All basic science articles were included. Clinical articles with less than 10 patients treated and less than 6 mo of follow-up were excluded. With these criteria, a total of 17 articles were available for the present review. RESULTS: PJAC and CAIS are relatively novel techniques for cartilage repair. Good basic science evidence was described to support the concept. Although the preliminary clinical reports show encouraging results, clinical data are still limited, especially for CAIS. The indications for both techniques need to be precisely defined(age of the patients, size of the lesion, and involvement of the subchondral bone), together with other debated issues. CONCLUSION: In conclusion, the authors can state that encouraging preliminary results are available for both techniques. However, further studies are necessary to precisely determine the indications, surgical techniques, and long term outcomes for PJAC and CAIS.Davide Edoardo Bonasia Antongiulio Marmotti Federica Rosso Gianluca Collo Roberto Rossi 2015World Journal of Orthopedics2015,6,11:5

19Influence of rejuvenators on bitumen ageing in hot recycled asphalt mixtures显示文摘The use of reclaimed asphalt pavement(RAP) in new hot mix asphalt(HMA) by means of hot recycling techniques generates the advantage linked to the exploitation of both lytic and bituminous component, consequently leading to the decrease of both virgin aggregates and bitumen supplying. However, many agencies and public administration authorise RAP percentages ranges from 10% to 30% in hot recycling. The main reason for such a low amount of allowable RAP content is related to the aged bitumen contained in the RAP materials, which is more brittle than a virgin bitumen leading to a final mixture more susceptible to fatigue, thermal and reflection cracking. The use of rejuvenators has the potential to restore rheology and chemical components of aged RAP bitumen, thus allowing a significant increase in the amount of RAP to be properly implemented in HMA.The experimental investigation is described in this paper and carried out through a dynamic shear rheometer(DSR) which provides the rheological characterisation of a paving grade bitumen during its overall service life including its reuse in hot recycling by adopting different rejuvenators.Results show that rejuvenators modify bitumen chemistry and consequently rheology by enhancing the viscous response. Moreover, it was observed that oxidation is less harmful, in terms of stiffness increase, on the 50/50 aged bitumen-virgin bitumen blends(rejuvenated or not) than on the virgin bitumen. Moreover, the addition of a rejuvenator in a bituminous blend containing 50% of bitumen reactivated from RAP could lead to a corresponding composite bituminous phase less subjected to ageing phenomena and even less stiff at the end of service life than the associated virgin bitumen alone.Giorgia Mazzoni Edoardo Bocci Francesco Canestrari 2018Journal of Traffic and Transportation Engineering(English Edition)2018,5,3:5
