| 3 | High-aspect 3D two-photon polymerization structuring with widened objective working range (WOW-2PP)显示文摘We developed a novel two-photon polymerization(2PP)configuration for fabrication of high-aspect three-dimensional(3D)structures,with an overall height larger than working distance of the microscope objective used for laser beam focusing into a photosensitive material.This method is based on a modified optical 2PP setup,where a microscope objective(1003 high N.A.),immersion oil and cover glass can be moved together into the photosensitive material,resulting in an effective higher and wider objective working range(WOW-2PP).The proposed technique enables the fabrication of high-aspect structures with sub-micrometer process resolution.3D structures with a height of 7 mm are demonstrated,which could hardly be built with the conventional 2PP set-up due to refractive index mismatch and laser beam disturbances. | Kotaro Obata Ayman El-Tamer Lothar Koch Ulf Hinze Boris N Chichkov | 2013 | Light(Science & Applications)2013,2,1: | 7 |

| 9 | Bcl-x_L and Myeloid cell leukaemia-1 contribute to apoptosis resistance of colorectal cancer cells显示文摘AIM: To explore the role of Bcl-xL and Myeloid cell leukaemia (Mcl)-1 for the apoptosis resistance of colorectal carcinoma (CRC) cells towards current treat-ment modalities. METHODS: Bcl-xL and Mcl-1 mRNA and protein ex-pression were analyzed in CRC cell lines as well as human CRC tissue by Western blot,quantitative PCRand immunohistochemistry. Bcl-xL and Mcl-1 protein expression was knocked down or increased in CRC cell lines by applying specific siRNAs or expression plas-mids,respectively. After modulation of protein expres-sion,CRC cells were treated with chemotherapeutic agents,an antagonistic epidermal growth factor recep-tor (EGFR1) antibody,an EGFR1 tyrosine kinase inhibi-tor,or with the death receptor ligand TRAIL. Apoptosis induction and cell viability were analyzed. RESULTS: Here we show that in human CRC tis-sue and various CRC cell lines both Bcl-xL and Mcl-1 are expressed. Bcl-xL expression was higher in CRC tissue than in surrounding non-malignant tissue,both on protein and mRNA level. Mcl-1 mRNA expression was significantly lower in ma-lignant tissues. However,protein expression was slightly higher. Viability rates of CRC cells were significantly decreased after knock down of Bcl-xL expression,and,to a lower extent,after knock down of Mcl-1 expression. Furthermore,cells with reduced Bcl-xL or Mcl-1 expression was more sensitive towards oxaliplatin-and irinotecan-induced apoptosis,and in the case of Bcl-xL also towards 5-FU-induced apoptosis. On the other hand,upregulation of Bcl-xL by transfec-tion of an expression plasmid decreased chemothera-peutic drug-induced apoptosis. EGF treatment clearly induced Bcl-xL and Mcl-1 expression in CRC cells. Apop-tosis induction upon EGFR1 blockage by cetuximab or PD168393 was increased by inhibiting Mcl-1 and Bcl-xL expression. More strikingly,CD95-and TRAIL-induced apoptosis was increased by Bcl-xL knock down. CONCLUSION: Our data suggest that Bcl-xL and,to a lower extent,Mcl-1,are important anti-apoptotic factors in CRC. Specific downregulation of Bcl-xL is a promising approach to sensitize CRC cells towards chemotherapy and targeted therapy. | Henning Schulze-Bergkamen Roland Ehrenberg Lothar Hickmann Binje Vick Toni Urbanik Christoph C Schimanski Martin R Berger Arno Schad Achim Weber Steffen Heeger Peter R Galle Markus Moehler | 2008 | World Journal of Gastroenterology2008,14,24: | 4 |
| 10 | Process engineering in circular economy显示文摘Driven by increasing global population and by growing demand for individual wealth,the consumption of energy and raw materials as well as the steadily growing CO_2 concentration in atmosphere pose great challenges to process engineering.This complex multi-scale discipline deals with the transformation of mass by energy to manifold products in different industrial fields under economical and ecological sustainable conditions.In growing circular economy,process engineering increasingly plays an important role in recovering valuable components from very diffuse material flows leaving the user stocks following widely variable time periods of use.As well it is engaged in thermal recovery of energy therefrom and in environmentally safe disposal of residual solid wastes whose recovery economically is not feasible.An efficient recovery of materials and energy following the laws of entropy is a must.A complex network of mass,energy,transportation and information flows has to be regarded with growing traded quantities of used goods even on global level.Important constraints in time,however,exist for a necessary realization of innovative new processes and communal mobility and industrial infrastructure on medium and large scale.Based on reasonable long term and highly reliable statistics from industrial organizations representing steel and paper industry,some limits and trends of possible developments in processing of those industries with long recycling experience will be discussed. | Lothar Reh | 2013 | Particuology2013,11,2: | 3 |
| 11 | Laser-assisted bioprinting at different wavelengths and pulse durations with a metal dynamic release layer:A parametric study显示文摘For more than a decade,living cells and biomaterials(typically hydrogels)are printed via laser-assisted bioprinting.Often,a thin metal layer is applied as laser-absorbing material called dynamic release layer(DRL).This layer is vaporized by focused laser pulses generating vapor pressure that propels forward a coated biomaterial.Different lasers with laser wavelengths from 193 to 1064 nanometer have been used.As a metal DRL gold,silver,or titanium layers have been used.The applied laser pulse durations were usually in the nanosecond range from 1 to 30 ns.In addition,some studies with femtosecond lasers have been published.However,there are no studies on the effect of all these lasers parameters on bioprinting with a metal DRL,and on comparing different wavelengths and pulse durations–except one study comparing 500 femtosecond pulses with 15 ns pulses.In this paper,the effects of laser wavelength(355,532,and 1064 nm)and laser pulse duration(in the range of 8 to 200 ns)are investigated.Furthermore,the effects of laser pulse energy,intensity,and focal spot size are studied.The printed droplet volume,hydrogel jet velocity,and cell viability are analyzed. | Lothar Koch Ole Brandt Andrea Deiwick Boris Chichkov | 2017 | International Journal of Bioprinting2017,3,1: | 3 |

| 14 | 22-gauge core vs 22-gauge aspiration needle for endoscopic ultrasound-guided sampling of abdominal masses显示文摘AIM To compare the aspiration needle(AN) and core biopsy needle(PC) in endoscopic ultrasound-guided fine needle aspiration(EUS-FNA) of abdominal masses.METHODS Consecutive patients referred for EUS-FNA were included in this prospective single-center trial. Each patient underwent a puncture of the lesion with both standard 22-gauge(G) AN(Echo Tip Ultra; Cook Medical, Bloomington, Indiana, United States) and the novel 22 G PC(Echo Tip Pro Core; Cook Medical, Bloomington, Indiana, United States) in a randomized fashion; histology was attempted in the PC group only. The main study endpoint was the overall diagnostic accuracy, including the contribution of histology to the final diagnosis. Secondary outcome measures included material adequacy, number of needle passes, and complications.RESULTS Fifty six consecutive patients(29 men; mean age 68 years) with pancreatic lesions(n = 38), lymphadenopathy(n = 13), submucosal tumors(n = 4), or others lesions(n = 1) underwent EUS-FNA using both of the needles in a randomized order. AN and PC reached similar overall results for diagnostic accuracy(AN: 88.9 vs PC: 96.1, P = 0.25), specimen adequacy(AN: 96.4% vs PC: 91.1%, P = 0.38), mean number of passes(AN: 1.5 vs PC: 1.7, P = 0.14), mean cellularity score(AN: 1.7 vs PC: 1.1, P = 0.058), and complications(none). A diagnosis on the basis of histology was achieved in the PC group in 36(64.3%) patients, and in 2 of those as the sole modality. In patients with available histology the mean cellularity score was higher for AN(AN: 1.7 vs PC: 1.0, P = 0.034); no other differences were of statistical significance.CONCLUSION Both needles achieved high overall diagnostic yields and similar performance characteristics for cytological diagnosis; histological analysis was only possible in 2/3 of cases with the new needle. | William Sterlacci Athanasios D Sioulas Lothar Veits Pervin G?nüllü Guido Schachschal Stefan Groth Mario Anders Christos K Kontos Theodoros Topalidis Andrea Hinsch Michael Vieth Thomas R?sch Ulrike W Denzer | 2016 | World Journal of Gastroenterology2016,22,39: | 2 |

| 17 | Analysis of the Interface between Primary and Secondary Metabolism in Catharanthus roseus Cell Cultures Using ^13C-Stable Isotope Feeding and Coupled Mass Spectrometry显示文摘Dear Editor, The tropical plant Madagascar periwinkle Catharanthus roseus (L.) G.Don is a rich source of plant-derived medicinal terpenoid indole alkaloids (TIAs),including the anti-hypertensive ajmalicine,the sedative compound serpentine,and the anticancer drugs vinblastine and vincristine.However,the latter two compounds are produced in C roseus plants only in very low amounts.Elicitors such as hormones (e.g.jasmonates or salicylic acid) activate plant natural defense responses,including increased secondary metabolite production (EI-Sayed and Verpoorte,2007;Lackman et al.,2011).There are two different metabolic pathways for the biosynthesis of terpenoids leading to the formation of the Cs central precursor isopentenyl diphosphate (IPP),namely the classical cytosolic mevalonate pathway and the mevalonate-independent plastidic 2-C-methyI-D-erythritol 4-phosphate (MEP) pathway. | Carla Antonio Natali R.

| 19 | Modelling and simulation of fixtures during grinding显示文摘The complex workpiece-fixture behaviour during machining is an essential component of the fixture development process.In detail,the forces acting on fixture components have to be analysed.A method for the prediction of the reaction forces due to process and clamping loads is presented in this article.At the beginning,detailed information about the workpiece-fixture behaviour during the process is determined by a complex finite element model.Secondly,the reduction of the number of elements leads to a smaller model with less computation time,validated and used for the variation of process parameters.Finally,an analytical description is developed based on the combination of both results.With the help of the empiric equation it is possible to predict the reaction forces and the dependency on several process parameters.This method has been validated by modelling shape grinding of a nozzle guide vane. | Matthias KLAERNER Juergen LEOPOLD Lothar KROLL | 2009 | Science China(Technological Sciences)2009,52,7: | 2 |
