| 1 | Liver sinusoidal endothelial and biliary cell repopulation following irradiation and partial hepatectomy显示文摘AIM: To investigate whether irradiation (IR) and partial hepatectomy (PH) may prepare the host liver for nonparenchymal cell (NPC) transplantation.METHODS: Livers of dipeptidyl peptidase(DPP)-deficient rats were pre-conditioned with external beam IR (25 Gy) delivered to two-thirds of the right liver lobules followed by a one-third PH of the untreated lob-ule. DPP-positive liver cells (NPC preparations enriched for liver sinusoidal endothelial cells (LSECs) and hepatocytes) were transplanted via the spleen into the recipient livers. The extent and quality of donor cell engraftment and growth was studied over a long-term interval of 16 wk after transplantation.RESULTS: Host liver staining demonstrated 3 different repopulation types. Well def ined clusters of donor-derived hepatocytes with canalicular expression of DPP were detectable either adjacent to or in between large areas of donor cells (covering up to 90% of the section plane) co-expressing the endothelial marker platelet endothelial cell adhesion molecule. The third type consisted of formations of DPP-positive duct-like structures which co-localized with biliary epithelial CD49f.CONCLUSION: Liver IR and PH as a preconditioning stimulus enables multiple cell liver repopulation by donor hepatocytes, LSECs, and bile duct cells. | Petra Krause Margret Rave-Frank Hendrik Andreas Wolff Heinz Becker Hans Christiansen Sarah Koenig | 2010 | World Journal of Gastroenterology2010，16，31： | 2 |

| 5 | 蜜蜂花粉采集器官和采集飞行的线性比例分析(英文)显示文摘本研究从采粉工蜂飞行中能量消耗相关的几个方面入手,分析了蜜蜂属(Apis) 8个物种的花粉采集器官。结果表明,花粉筐表面积、翅膀表面积、体重及胸部动力容量与蜂种个体的体长呈极显著相关,并且它们随蜂种个体的增大而呈对数线性比例增加。除意大利蜜蜂(A·mellifera ligustica)以外,花粉团重量与花粉筐和基跗节表面积成线性比例。工蜂负重前后重量的变化与花粉筐和翅膀的表面积不成比例[动物学报51 (5) :947 -951 , 2005]。 | Randall HEPBURN Sarah RADLOFF Nikolaus KOENIGER Gudrun KOENIGER Salim TINGEK | 2005 | 动物学报2005，51，5： | 0 |
