Zhongguo shiyan zhenduanxue, 2015 目前,食管癌是一种常见的恶性肿瘤,组织学分型可分为鳞癌、腺癌等,其中以鳞癌最为常见,约占90%以上,而原发性的食管小细胞癌（PESC）则更为罕见。近年来,随着病理学技术的发展,以及食管癌外科手术切除技术的提高,文献报道的PESC发病率有所上升。由于国内的食管癌整体发病率高于国外,因此,近年来国内所报道的病例要明显多于国外。PESC的镜下、影像学以及临床表现与鳞癌、腺癌相类似,但其生物学特性、组织来源 ...

Conservation Biology, Volume 39, Issue 6, December 2025.Abstract Forest cover is positively associated with fish biomass and fisheries yield in the Amazon River floodplain, and many species enter flooded forests to feed, spawn, or seek refuge from predation. Floating macrophyte beds, known as floating meadows, in Amazon floodplains support high fish diversity and serve as nursery habitat for many fishes of ...

Stationary and dynamical properties of a zero range process on scale-free networks
, 2005 We study the condensation phenomenon in a zero range process on scale-free networks. We show that the stationary state property depends only on the degree distribution of underlying networks. The model displays a stationary state phase transition between
