Existing auto-focusing methods in laser processing typically include two independent modules,one for surface detection and another for z-axis *** latter is mostly implemented by mechanical z stage motion,which is up to three orders of magnitude slower than the lateral processing *** alleviate this processing bottleneck,we developed a single-lens approach,using only one high-speed z-scanning optical element,to accomplish both in situ surface detection and focus control quasi-simultaneously in a dual-beam *** probing beam scans the surface along the z-axis continuously,and its reflection is detected by a set of confocal *** on the temporal response of the detected signal,we have developed and experimentally demonstrated a dynamic surface detection method at 140-350 kHz,with a controlled detection range,high repeatability,and minimum linearity error of 1.10%.Sequentially,by synchronizing at a corresponding oscillation phase of the z-scanning lens,the fabrication beam is directed to the probed z position for precise focus ***,our approach provides instantaneous surface tracking by collecting position information and executing focal control both at 140-350 kHz,which significantly accelerates the axial alignment process and offers great potential for enhancing the speed of advanced manufacturing processes in three-dimensional space.

World Journal of Gastroenterology 2005年第34期11卷 5295-5302页

作者： Marie-Luise Lemken Wolfgang A.Wybranietz Ulrike schmidt florian Graepler Sorin Armeanu Michael Bitzer Ulrich M.Lauer Department of Internal Medicine I University Clinic Tübingen D-72076 Tübingen Germany

AIM： To generate and characcerize the synthetic transoiptional control units for transcriptional targeting of the liver, thereby compensating for the lack of specificity of currently available gene therapeutic vector systems. METHODS： Synthetic transcriptional control unit constructs were generated and analyzed for transcriptional activities in different cell types by FACS quantification, semi-quantitative RT-PCR, and Western blotting. RESULTS： A new bifunctionally-enhanced green fluorescent protein （EGFP）/neor fusion gene cassette was generated, and could flexibly be used both for transcript quantification and for selection of stable cell clones. Then, numerous synthetic transcriptional control units consisting of a minimal promoter linked to “naturally” derived composite enhancer elements from liver-specific expressed genes or binding sites of liver-specific transcription factors were inserted upstream of this reporter cassette. Following liposome-mediated transfection, EGFP reporter protein quantification by FACS analysis identified constructs encoding multimerized composite elements of the apolipoprotein B100 （APOB） promoter or the ornithin transcarbamoylase （OTC） enhancer to exhibit maximum transcriptional activities in liver originating cell lines, but only background levels in non-liver originating cell lines. In contrast, constructs encoding only singular binding sites of liver-specific transcription factors, namely hepatocyte nuclear factor （HNF）, HNF3, HNF4, HNF5, or CAAT/enhancer binding protein （C/EBP） only achieved background levels of EGFP expression. Finally, both semi-quantitative RT-PCR and Western blotting analysis of Hep3B cells demonstrated maximum transcriptional activities for a multimeric 4xAPOB cassette construct, which fully complied with the dataobtained by initial FACS analysis CONCLUSION： Synthetic transcriptional control unit constructs not only exhibit a superb degree of structural compactness, but also provide new means for liver

AIM： To investigate the effects of catalytically superior gene-directed enzyme prodrug therapy systems on a rat hepatoma model. METHODS： To increase hepatoma cell chemosensitivity for the prodrug 5-fluorocytosine （5-FC）, we generated a chimeric bifunctional SuperCD suicide gene, a fusion of the yeast cytosine deaminase （YCD） and the yeast uracil phosphoribosyltransferase （YUPRT） gene. RESULTS： In vitro stably transduced Morris rat hepatoma cells （MH） expressing the bifunctional SuperCD suicide gene （MH SuperCD） showed a clearly marked enhancement in cell killing when incubated with 5-FC as compared with MH cells stably expressing YCD solely （MH YCD） or the cytosine deaminase gene of bacterial origin （MH BCD）, respectively. In vivo, MH SuperCD tumors implanted both subcutaneously as well as orthotopically into the livers of syngeneic ACI rats demonstrated significant tumor regressions （P〈0.01） under both high dose as well as low dose systemic 5-FC application, whereas MH tumors without transgene expression （MH naive） showed rapid progression. For the first time, an order of in vivo suicide gene effectiveness （SuperCD〉〉 YCD〉〉BCD〉〉〉negative control） was defined as a result of a direct in vivo comparison of all three suicide genes. CONCLUSION： Bifunctional SuperCD suicide gene expression is highly effective in a rat hepatoma model, thereby significantly improving both the therapeutic index and the efficacy of hepatocellular carcinoma killing by fluorocytosine.

Journal of Cancer Therapy 2013年第8期4卷 1306-1312页

Approximately 6% of patients with breast cancer have distant metastases at the time of the initial diagnosis. The aim of this analysis was to examine the overall survival rate over time and to investigate the effect of new therapy options. Methods: This retrospective analysis was performed based on the data bank of the Clinic for Gynaecological Oncology/Dr. Horst schmidt Klinik, Wiesbaden and the Clinic for Gynaecological Oncology and Senology/Kliniken Essen Mitte, Essen. The patients with primary metastatic breast cancer (pmBC) who were diagnosed and treated at the accredited breast cancer centres of these clinics were enrolled between 1998 and 2007. The date of diagnosis was used to define 2 specifically chosen 5-year periods: 1998-2002 and 2003-2007. The follow-up time was on average 76 months. The Breslow Test was used to evaluate changes in the median survival time and to detect factors associated with the increase in survival rates. Results: Two hundred sixteen patients with complete baselines were analysed. Ninety patients were diagnosed between 1998 and 2002, and 126 patients received their diagnosis of pmBC between 2003 and 2007. The tumour-biological factors were the same in both groups, whereas the therapeutic concepts were different—the later group (2003-2007) received more aromatase inhibitors, taxane-based chemotherapy and trastuzumab. This finding resulted in an increased median survival time from 31 months in the years 1998-2002 to 44 months in the group with the first diagnosis between 2003 and 2007. Conclusions: Primary metastatic breast cancer occurred at constant rates over last 10 years. The tumour findings did not change in the time between the two examined groups;however, the treatment options in the 2003-2007 group included newly approved therapies. The time period of the first diagnosis was detected as a risk factor for overall survival. Those patients diagnosed in the more recent time frame had a significantly improved survival rate. The es

Effects of Natural Radiation, PAR and Artificial Ultraviolet Radiation-B on the Ultrastructure and Histochemistry of Leaf of Oryza sativa L.

引用

American Journal of Plant Sciences 2012年第10期3卷 1361-1368页

作者： Sérgio L. de Almeida éder C. schmidt Ana C. Rodrigues Zenilda L. Bouzon Central Laboratory of Electron Microscopy Federal University of Santa Catarina Florianópolis Brazil Department of Botany Federal University of Santa Catarina Florianópolis Brazil Post-Graduate Program in Cell Biology and Development Department of Cell Biology Embryology and Genetics Federal University of Santa Catarina Florianópolis Brazil

Ultraviolet radiation-B (UVBR) affects plants in many important ways, including reduced growth rate, reduction of primary productivity and changes in ultrastructure. The rice (Oryza sativa) is one of the most cultivated cereal in the world along with corn and wheat, representing over 50% of agricultural production. In this study, we examined O. sativa exposed to natural radiation denominated which “ambient samples”, plants cultivated which photosynthetically active radiation (PAR), denominated with PAR-only and plants cultivated with PAR + UVBR for 2 h per day during 30 days of cultivation in vitro. The samples were processed for electron microscopy and histochemistry analysis. PAR + UVBR caused changes in the ultrastructure of leaf of O. sativa, mesophyll cells, which included increased thickness of the cell wall and plastoglobuli, reduced intracellular spaces, changes in the cell contour, and destruction of chloroplast and mitochondria internal organization. The exposure to PAR + UVBR led to changes in guard and subsidiary cells, and the stomata and papillae were with irregular shape. The reduction of epicuticular wax that covered the leaf, was observed. Taken together, these ?ndings strongly suggested that PAR + UVBR negatively affects the ultrastructure and morphology and growth rates, of leaf of O. sativa and, in the long term, their economic viability.
