Based on the commercially available avalanche photodiodes, the basic needs of gated-mode operation for single photon are discussed. gated-mode technique based on the experimental data for detection of single photon is analyzed at communication wavelengths so that the basic operation parameters can decide properly for efficient detection of single photon. The bias voltage has related to the punch-through voltage in combining the cooling technique with synchronization to decrease the dark counts.

Effects of extracellular matrix proteins on expansion, proliferation and insulin-producing-cell differentiation of ARIP cells

Regeneration of transplantable pancreatic islet cells has been considered to be a promising alternative therapy for type 1 diabetes. Re-search has suggested that adult pancreatic stem and progenitor cells can be derived into insulin-producing cells or cultivated islet-like clusters given appropriate stimulating condi- tions. In this study we explored the effect of selective extracellular matrix (ECM) proteins on the potential of insulin-producing cell differen-tiation using ARIP cells, an adult rat pancreatic ductal epithelial cell line, as a model in vitro. Quantitative single cell morphology analysis indicated that all the four ECM proteins we have used (type I collagen, laminin, fibronectin and vitronectin) increased the single cell area and diameter of ARIP cells. In addition, se-rum-free cell cultivation was dependent on cell density and particular components;and serum could be replaced when systematic optimisa-tion could be performed. Surface treated with laminin was shown to be able to enhance overall cell expansion in the presence of de-fined serum-free medium conditions. Collagen treated surfaces enhanced insulin production in the presence of gLP-1 although the insulin gene expression was however weak accord-ingly. Our results suggest that selective ECM proteins have effects on single cell morphol-ogy, adhesion and proliferation of ARIP cells. These ECM molecules however do not have a potent effect on the insulin-producing cell dif-ferentiation potential of ARIP cells even com-bining with gLP-1.

手术产与产后抑郁症关系的队列研究

世界核心医学期刊文摘（妇产科学分册） 2005年第9期1卷 1-2页

作者： Patel R.R. Murphy D.J. Peters T.J. 王佳楣 Division of Obstetrics University of Bristol St. Michael's Hospital Bristol BS2 8EG United Kingdom

Objectives: To assess the association between elective caesarean section and p ostnatal depression compared with planned vaginal delivery and whether emergency caesarean section or assisted vaginal delivery is associated with postnatal dep ression compared with spontaneous vaginal delivery. Design: Prospective populati on based cohort study. Setting: ALSPAC (the Avon longitudinal study of parents a nd children). Participants: 14 663 women recruited antenatally with a due date b etween 1 April 1991 and 31 December 1992. Main outcome measure: Edinburgh postna tal depression scale score ≥13 at eight weeks postnatal on self completed quest ionnaire. Results: Albeit with wide confidence intervals, there was no evidence that elective caesarean section altered the odds of postnatal depression compared with plann ed vaginal delivery (adjusted odds ratio 1.06, 95%confidence interval 0.66 to 1 .70, P = 0.80). Among planned vaginal deliveries there was similarly little evid ence of a difference between women who have emergency caesarean section or assis ted vaginal delivery and those who have spontaneous vaginal delivery (1.17, 0.77 to 1.79, P = 0.46, and 0.89, 0.68 to 1.18, P = 0.42, respectively). Conclusions : There is no reason for women at risk of postnatal depression to be managed dif ferently with regard to mode of delivery. Elective caesarean section does not pr otect against postnatal depression. Women who plan vaginal delivery and require emergency caesarean section or assisted vaginal delivery can be reassured that t here is no reason to believe that they are at increased risk of postnatal depression.

用溶胶-凝胶法制备了不同掺杂量的N/TiO2复合纳米粉末,采用X射线衍射(XRD)、扫描透镜(TEM)、紫外-可见反射吸收光谱(UV-vis)对催化剂进行了初步表征.通过X射线光电子能谱(XPS)、元素分析仪(EA)测定其含氮量.XPS分析结果显示TiO2晶格中的氧被氮原子取代,N/TiO2表面存在Ti3+离子;紫外-可见反射吸收光谱测得不同掺杂量的N/TiO2的禁带宽度(eg),推测在TiO2价带上方生成了由N诱导产生的中间带,当氮、钛摩尔比为0.0880时N/TiO2的eg最小,为2.50eV.在可见光下,以酸性桃红(SRB)和无色小分子对氯苯酚(4-CP)作为可见光活性实验的探针反应,确定了最佳掺杂比为nN/nTi=0.0880.结果表明,最佳掺杂量下N/TiO2能显著降解SRB和4-CP,通过测定ESR,IR,TOC,COD,重点比较了TiO2在掺杂N前后在降解SRB和4-CP时的差异,包括氧化物种、矿化率、最终产物等,证明在可见光下,N/TiO2的降解机理为电子从独立的N2p轨道激发到Ti3d轨道,产生羟基自由基等氧化物种,达到降解有机物的目的.
