在20世纪晚期,现代主义建筑成为一种普遍的风格和形式,功能主义的核心、超越的统一的学说、纯正的美学价值被纳入文化和社会整体性能最基本的方式。现代主义似乎就是这样一个门户,充满激进和创新的艺术思想。从浪漫主义中产生的实验性、技术性和美学思想都陷入了形式危机。面对现代艺术形式词汇中的"失去意义",现代主义的审美价值不再被认为是绝对的和不可改变的,其审美文化地位和理论视野得到了充分的调整。文章探讨了现代主义建筑名师的贡献和作用,以期为现代主义建筑的雅致化进程提供更多思考。

BACKGROUND: Type 1 diabets is an autoimmune disease caused by the destruction of pancreatic β-cell with an in- creased incidence worldwide in the closing decades of the 20th century. This study was to investigate the effects of human umbilical cord serum (UCS) on the proliferation and function of human fetal islet-like cell clusters (ICCs) in vitro. METHODS: Eight fresh pancreatic glands obtained after in- duction of labor with water bag were mildly exposed to col- lagenase V, and the digested cells were cultured in a RPMI- 1640 medium plus 10% pooled UCS or fetal calf serum (FCS) to permit cells attachment and outgrowth of ICCs. RESULTS: In 8 consecutively explanted glands, develop- ment and proliferation of ICCs were observed. In the pre- sence of FCS, the outgrowth of ICC took place on the top of a flbroblast monocellular layer. UCS affected less growth of fibroblasts and increased the formation of ICCs about four-fold compared with explants from the same glands maintained in FCS. In both UCS and FCS, the insulin con- tent of the medium was variable to a certain extent and progressively declined from day 2 to day 6. Dithizone- stained ICCs in UCS suggested that most cell clusters were islet cells ( β-cells), and the purity of islets was estimated 80%-90%. The ultrastructure of the cultured cells showed a large number of granule-containing cells, most of which were identified as β-cells. CONCLUSION: We conclude that in comparison with ex- plants with FCS, the yield of ICCs and purification of islet cells are markedly increased by UCS and may facilitate the proliferation of pancreatic β-cells intended for islet trans- plantation.

组织温度改变是影响神经传导速度(NCV)常规检查唯一最明显的非病理性因素。若干体内外因素可能引起上肢或下肢组织温度改变。为了控制 NCV 测定时的体外因素如室温的变化,某些研究者采取测试前先在恒温室内适应30分钟以期减少 NCV的改变。这对肢体远体段 NCV 的测定尤为重要,因在较低温的环境,其温度可能低于体温。温度较低的肢体在恒温室内恢复到正常组织温度所需要的时间可能更长些。NCV 测定前所需的室温和适应时间没有具体规定。

Background: Dental implant is an artificial root inserted in the jawbone, which restores a lost tooth so that it looks, feels, and is fit like a natural tooth. It is considered to be the best treatment option for single or multiple missing teeth. The aim of this study was to assess the awareness of patients about dental implants as an alternative treatment in Congolese patients. Materials and Methods: A cross-sectional study was conducted in two institutions namely, CBCO Bandal and Ngaliema Clinic, from August to December 2017. A total of 450 respondents have participated in the survey. A printed questionnaire comprised of 20 questions in order to evaluate patients dental awareness was used. Gender, level of education, awareness of dental implant and dental implants therapy, sources of information and the expectation about the sources of information were assessed. The collected data were entered in Microsoft Excel 2010 and analyzed by SPSS (IBM SPSS 20.0, Chicago, IL, USA) software. Results: Out of 450 participants, 14.4% were aware of dental implants. The main disadvantage of dental implant was the high cost. When asked about the anchorage, 86% didn’t know where the dental implant was anchored. Ninety-two percent didn’t know for how long an implant last, 6% thought that dental implant last for a lifetime. When patients were asked about the sources of information, the dentist (5%) and media (5.5%) were the main sources of information. The majority of patients (88.4%) would like to get information about dental implants from their dentist. Conclusion: Dentists should be more involved in the promotion of information about dental implants as a treatment modality to replace missing teeth.
