A newly recognized syndrome of marfanoid habitus; Long face; Hypotelorism; Long, thin nose; Long, thin hands and feet; and a specific pattern of language and learning disabilities

Here, we report on a newly recognized syndrome in a Brazilian family with three affected women, who had a Marfanoid habitus; long face; hypotelorism; long, thin nose; long, thin hands and feet; and language and learning disabilities. The disorder is compatible with autosomal dominant inheritance. (C) 2007 Wiley-Liss, Inc.

Cytotoxicity of denture base and hard chairside reline materials: a systematic review

Statement of problem. Adverse reactions to the materials used for the fabrication and reline of removable denture bases have been observed.Purpose. The purpose of this study was to systematically review the published literature on the cytotoxicity of denture base and hard reline materials.Material and methods. MEDLINE via PubMed, Google Scholar, and Scopus databases for the period January 1979 to December 2009 were searched with the following key words: (biocompatibility OR cytotoxic* OR allergy OR burning mouth OR cell culture techniques) and (acrylic resins OR denture OR monomer OR relin* OR denture liners). The inclusion criteria included in vitro studies using either animal or human cells, in which the cytotoxicity of the denture base and hard chairside reline resins was tested. Studies of resilient lining materials and those that evaluated other parameters such as genotoxicity and mutagenicity were excluded. Articles published in the English language and in peer-reviewed journals focusing on the cytotoxicity of these materials were reviewed.Results. A total of 1443 articles were identified through the search. From these, 20 studies were judged to meet the selection criteria and were included in the review. In the majority of the studies, continuous cell lines were exposed to eluates of specimens made from the materials, and mitochondrial activity was used to estimate cell viability. The tested acrylic resins were grouped according to 5 major categories: (1) heat-polymerized; (2) microwave-polymerized; (3) autopolymerizing; (4) light-polymerized; and (5) hard chairside reliners.Conclusions. This review provided some evidence that the heat-polymerized resins showed lower cytotoxic effects than autopolymerizing denture base acrylic resins and light or dual polymerized reline resins. However, because of the large number of variables in the reviewed literature, a definitive conclusion could not be drawn. (J Prosthet Dent 2012;107:114-127)

Linguagem poética e crescimento urbano-industrial / Poetical language and urban-industrial growth

O impacto do crescimento urbano-industrial sobre a lírica moderna é abordado sob o ângulo das dissonâncias ocorridas entre as representações temáticas e os procedimentos expressivos. Assim se confrontam as “respostas” dos poetas europeus à Revolução Industrial e o surgimento das grandes cidades com as dos modernistas brasileiros de 22 face à industrialização de São Paulo. Nestes, ao contrário dos primeiros, os conflitos instauram-se entre a celebração programática da vida moderna e, num primeiro momento, a impossibilidade de adequação de suas formas de expressão ao registro dessa modernidade. Dessa forma se explicam os desequilíbrios temático-expressivos existentes em Paulicéia Desvairada, bem como as adequações conseguidas por obras posteriores. The impact of urban-industrial growth on modern lyrics is approached from the angle of the dissonances which occurred between the thematic representations and the expressive procedures. Thus, the European poets’ responses to the Industrial Revolution and the emergence of the large cities are confronted with those of the 1922 Brazilian Modernists in relation to the industrialization of São Paulo. In the latter, contrary to what happened with ther former ones, the conflicts take place between the programmatic celebration of modern life and, at first, the impossibility of adequating their form of expressions to the record of said modernity. Thus the thematic-expressive disequilibrium in Paulicéia Desvairada, as well as de adequations obtained in later works are explained.
