Somatic and germ cell parasitism in a colonial ascidian: Possible role for a highly polymorphic allorecognition system

A colonial protochordate, Botryllus schlosseri, undergoes a natural transplantation reaction in the wild that results alternatively in colony fusion (chimera formation) or inflammatory rejection. A single, highly polymorphic histocompatibility locus (called Fu/HC) is responsible for rejection versus fusion. Gonads are seeded and gametogenesis can occur in colonies well after fusion, and involves circulating germ-line progenitors. Buss proposed that colonial organisms might develop self/non-self histocompatibility systems to limit the possibility of interindividual germ cell “parasitism” (GCP) to histocompatible kin [Buss, L. W. (1982) Proc. Natl. Acad. Sci. USA 79, 5337–5341 and Buss, L. W. (1987) The Evolution of Individuality (Princeton Univ. Press, Princeton]. Here we demonstrate in laboratory and field experiments that both somatic cell and (more importantly) germ-line parasitism are a common occurrence in fused chimeras. These experiments support the tenet in Buss’s hypothesis that germ cell and somatic cell parasitism can occur in fused chimeras and that a somatic appearance may mask the winner of a gametic war. They also provide an interesting challenge to develop formulas that describe the inheritance of competing germ lines rather than competing individuals. The fact that fused B. schlosseri have higher rates of GCP than unfused colonies additionally provides a rational explanation for the generation and maintenance of a high degree of Fu/HC polymorphism, largely limiting GCP to sibling offspring.

Expression of a Hox gene, Cnox-2, and the division of labor in a colonial hydroid

We report the isolation and expression of the Hox gene, Cnox-2, in Hydractinia symbiolongicarpus, a hydrozoan displaying division of labor. We found different patterns of aboral-to-oral Cnox-2 expression among polyp polymorphs, and we show that experimental conversion of one polyp type to another is accompanied by concordant alteration in Cnox-2 expression. Our results are consistent with the suggestion that polyp polymorphism, characteristic of hydractiniid hydroids, arose via evolutionary modification of proportioning of head to body column.

Physical and chemical evaluation of furniture waste briquettes

Furniture waste is mainly composed of wood and upholstery foam (mostly polyurethane foam). Both of these have a high calorific value, therefore, energy recovery would be an appropriate process to manage these wastes. Nevertheless, the drawback is that the energy content of these wastes is limited due to their low density mainly that of upholstery foam. Densification of separate foam presents difficulties due to its elastic character. The significance of this work lies in obtaining densified material by co-densification of furniture wood waste and polyurethane foam waste. Densification of furniture wood and the co-densification of furniture wood waste with polyurethane foam have been studied. On the one hand, the parameters that have an effect on the quality of the furniture waste briquettes have been analysed, i.e., moisture content, compaction pressure, presence of lignin, etc. The maximum weight percentage of polyurethane foam that can be added with furniture wood waste to obtain durable briquettes and the optimal moisture were determined. On the other hand, some parameters were analysed in order to evaluate the possible effect on the combustion. The chemical composition of waste wood was compared with untreated wood biomass; the higher nitrogen content and the concentration of some metals were the most important differences, with a significant difference of Ti content.

O patrimônio invisível: arquitetura popular urbana de municípios do período colonial brasileiro

No Brasil, ações institucionais de preservação de bens imóveis tem foco principal na arquitetura erudita, colocando em segundo plano de importância a arquitetura produzida por indivíduos com formação escassa e empírica. Este trabalho contribui para o reconhecimento da arquitetura popular (vernácula) como patrimônio cultural. Trabalha-se na criação de acervo fotográfico de edificações e equipamentos urbanos produzidos durante o período colonial, nos municípios de Tiradentes, Mariana, Ouro Preto e Diamantina (Minas Gerais). São realizadas visitas in loco para reconhecimento e seleção de objetos a serem fotografados. O registro fotográfico é realizado com câmera digital reflex de objetiva simples, privilegiando-se objetos cuja deterioração permite a observação de materiais e técnicas construtivas. Como resultado parcial da pesquisa, foram produzidas 4.522 imagens, documentando o abandono de edificações residenciais e chafarizes setecentistas e oitocentistas, bem como a descaracterização de exemplares de edificações coloniais populares habitadas, cujas paredes de adobe e pau-a-pique são substituídas por alvenaria de tijolos pelos moradores. Tornam-se necessárias ações para o reconhecimento – no âmbito do Poder Público e das comunidades locais – da relevância histórica da arquitetura popular, entendida como produto articulado e coerente de contribuições das culturas distintas que formaram essa região do Brasil.
