近期的研究极大地丰富了亚洲古新世和早始新世哺乳动物群信息,因此有必要对现存亚洲生物年代学和生物地理学框架做出调整。在定量和定性分析的基础上,将生物年代界线与主要的动物群更替事件对应起来,改进了古新世和早始新世亚洲陆相哺乳动物分期年代对比及生物地理学的认识。以往知之甚少的上湖期以原始啮形类和钝脚类为主,其后的浓山期则呈现出亚洲哺乳动物的地方性分异。随着新的基干啮形类以及真正的啮型类的出现,啮形类开始辐射。上湖期-浓山期的界线与北美Torrejonian-Tiffanian界线相当,并且动物群更替很可能是由全球变冷阶段的开始引发的。格沙头期哺乳动物进一步分化,亚洲土著类群急剧减少,以多瘤齿兽类、夜鼩类(nyctitheriids)、克莫土兽类(cimolestids)和食果猴为代表的北美迁入物种开始出现。而在北美,亚洲哺乳动物(包括北柱兽类和原恐角兽类)的第一次入侵发生于Tiffanian-5a期初期,第二次入侵发生于Clarkforkian初期,包含了啮齿类、裂齿类及冠齿兽类。因此格沙头期的开始可与北美Tiffanian-5a的开始相对比。伯姆巴期的开始以偶蹄类、奇蹄类和真灵长类的首次出现为标志,与古新世-始新世界线相当。这些类群在亚洲的出现与它们在北美和欧洲出现于始新世之初的情况类似。与格沙头期初期的动物群扩散不同,伯姆巴期的动物群扩散似乎持续了更长时间,并且也有可能直接发生在亚洲和欧洲之间。

作者： Dirk pieter Hogerzeil Imraan Muradin Eline W Zwitser Joris A Jansen Department of Orthopedic Surgery Alrijne Hospital

Acute compartment syndrome(ACS) of the thigh following primary total hip arthroplasty(THA) is a highly uncommon complication and has not yet been reported before with regards to the anterior approach through the anterior supine interval. We present a case of a 69-year-old male patient with a history of stroke, who developed ACS of the thigh after elective THA while using therapeutic low molecular weight heparin as bridging for regular oral anticoagulation. ACS pathogenesis, diagnostic tools, treatment and relevant literature are discussed. The patient's ACS was recognized in time and treated by operative decompression with fasciotomy of the anterior compartment. Follow-up did not show any neurological deficit or soft-tissue damage.

Morphological,anatomical,chemical and molecular data suggest that a relatively common lichenicolous coelomycete on Lecanora conizaeoides is conspecific with Phoma cytospora,previously known only from parmelioid lichens,and that further populations on Cladonia and Pertusaria belong to the same *** species is distinguished from Phoma by several taxonomically important characters and obviously represents a previously unrecognized genus,for which the name Briancoppinsia is *** analyses using nuLSU and mtSSU sequences of isolates obtained in pure culture suggest that the new genus belongs to the Arthoniaceae(Arthoniales).This is the first obligate lichenicolous,non-lichenized anamorph confirmed to belong to the Arthoniales based on molecular data.

AIM: To examine the expression of E-cadherin, β-catenin,γ-catenin, VEGF, and p53 in 39 patients with hepatic metastasis from colorectal cancer ***: The patients were divided into two groups:those (n = 16) who had no chemotherapy for at least 6 mo before the liver resections and those (n = 23)who were treated with chemotherapy before liver resections. A score from 0 to 3 was given for the number of positive cells and from 0 to 3 for the intensity of staining in these cells, in both healthy and metastatic liver ***: No significant differences in the expression of E-cadherin, β- and γ-catenin, VEGF and p53, could be observed between patients who received and did not receive chemotherapy, in both normal and metastatic liver ***: Despite the assumption that chemotherapy had an effect on liver metastasis, no influences were noticed immunohistochemically.

In the liteature on the mathematical description of social phenomena the concept of a network is hardly *** this paper we focus on the development of a’possible mathematical formualtion of the properties of a social network and a minimal and nearly complete social relational subsystem as a quasi-network within the setting of an economic trade system.
