| 2 | Proteome analysis of human mesenchymal stem cells undergoing chondrogenesis when exposed to the products of various magnesium-based materials degradation显示文摘Treatment of physeal fractures(15%–30%of all paediatric fractures)remains a challenge as in approximately 10%of the cases,significant growth disturbance may occur.Bioresorbable Magnesium-based implants represent a strategy to minimize damage(i.e.,load support until bone healing without second surgery).Nevertheless,the absence of harmful effects of magnesium-implants and their degradation products on the growth plate should be confirmed.Here,the proteome of human mesenchymal stem cells undergoing chondrogenesis was evaluated when exposed to the products of various Magnesium-based materials degradation.The results of this study indicate that the materials induced regulation of proteins associated with cell chondrogenesis and cartilage formation,which should be beneficial for cartilage regeneration. | Adela Helvia Martínez Sánchez Maryam Omidi Marcus Wurlitzer Marceline Manka Fuh Frank Feyerabend Hartmut Schlüter Regine Willumeit-Römer Bérengère J.C.Luthringer | 2019 | Bioactive Materials2019,4,1: | 2 |

| 9 | The all-diode-pumped laser system POLARIS——an experimentalist's tool generating ultra-high contrast pulses with high energy显示文摘The development,the underlying technology and the current status of the fully diode-pumped solid-state laser system POLARIS is reviewed.Currently,the POLARIS system delivers 4 J energy,144 fs long laser pulses with an ultra-high temporal contrast of 5 × 1012 for the ASE,which is achieved using a so-called double chirped-pulse amplification scheme and cross-polarized wave generation pulse cleaning.By tightly focusing,the peak intensity exceeds 3.5 × 1020 W cm-2.These parameters predestine POLARIS as a scientific tool well suited for sophisticated experiments,as exemplified by presenting measurements of accelerated proton energies.Recently,an additional amplifier has been added to the laser chain.In the ramp-up phase,pulses from this amplifier are not yet compressed and have not yet reached the anticipated energy.Nevertheless,an output energy of 16.6 J has been achieved so far. | Marco Hornung Hartmut Liebetrau Andreas Seidel Sebastian Keppler Alexander Kessler Jrg Krner Marco Hellwing Frank Schorcht Diethard Klpfel Ajay K.Arunachalam Georg A.Becker Alexander Svert Jens Polz Joachim Hein Malte C.Kaluza | 2014 | High Power Laser Science and Engineering2014,2,3: | 1 |

| 15 | Digital single-operator video cholangioscopy improves endoscopic management in patients with primary sclerosing cholangitis-a retrospective observational study显示文摘BACKGROUND Patients with primary sclerosing cholangitis(PSC)are at a high risk of developing cholestatic liver disease and biliary cancer,and endoscopy is crucial for the complex management of these patients.AIM To clarify the utility of recently introduced digital single-operator video cholangioscopy(SOVC)for the endoscopic management of PSC patients.METHODS In this observational study,all patients with a history of PSC and in whom digital SOVC(using the SpyGlass DS System)was performed between 2015 and 2019 were included and retrospectively analysed.Examinations were performed at a tertiary referral centre in Germany.In total,46 SOVCs performed in 38 patients with a history of PSC were identified.The primary endpoint was the evaluation of dominant biliary strictures using digital SOVC,and the secondary endpoints were the performance of selective guidewire passage across biliary strictures and the diagnosis and treatment of biliary stone disease in PSC patients.RESULTS The 22 of 38 patients had a dominant biliary stricture(57.9%).In 4 of these 22 patients,a cholangiocellular carcinoma was diagnosed within the stricture(18.2%).Diagnostic evaluation of dominant biliary strictures using optical signs showed a sensitivity of 75%and a specificity of 94.4%to detect malignant strictures,whereas SOVC-guided biopsies to gain tissue for histopathological analysis showed a sensitivity of 50%and a specificity of 100%.In 13%of examinations,SOVC was helpful for guidewire passage across biliary strictures that could not be passed by conventional methods(technical success rate 100%).Biliary stone disease was observed in 17.4%of examinations;of these,in 37.5%of examinations,biliary stones could only be visualized by SOVC and not by standard fluoroscopy.Biliary stone treatment was successful in all cases(100%);25%required SOVC-assisted electrohydraulic lithotripsy.Complications,such as postinterventional cholangitis and pancreatitis,occurred in 13%of examinations;however,no procedure-associated mortality occurred.CONCLUSION Digital SOVC is effective and safe for the endoscopic management of PSC patients and may be regularly considered an additive tool for the complex endoscopic management of these patients. | Arne Bokemeyer Frank Lenze Viorelia Stoica Timur Selcuk Sensoy Iyad Kabar Hartmut Schmidt Hansjoerg Ullerich | 2022 | World Journal of Gastroenterology2022,28,20: | 1 |
