Composi??o, abundancia e notas sobre a ecologia de espécies de larvas de lepidópteros associadas a cinco espécies de plantas hospedeiras no Parque Nacional da Restinga de Jurubatiba, RJ
Monteiro, Ricardo F.;Macedo, Margarete V.;Nascimento, Milena de S.;Cury, Rafael S. F.;
Revista Brasileira de Entomologia , 2007, DOI: 10.1590/S0085-56262007000400012
Abstract: in order to describe the species composition, temporal occurrence and ecological aspects of larvae associated with five plant species: erythroxylum ovalifolium and e. subsessile (erythroxylaceae), manilkara subsericea (sapotaceae), protium icicariba and p. heptaphyllum (burseraceae), 1.680 plants were bimonthly surveyed from july of 2003 to august of 2005 in the parque nacional da restinga de jurubatiba (pnrj). thirty two species of lepidoptera were reared from these five host plants, and the most abundant four species belonged to the elachistidae. manilkara subsericea showed the greatest number of lepidoptera species associated, 14 species, followed by e. ovalifolium (10 species), p. icicariba (seven species), e. subsessile (six species) and p. heptaphyllum (two species). only one out of the 32 species of lepidoptera was gregarious and 56% used any kind of shelter to get food or for defence. six lepidoptera species (27%) were polyphagous, three (14%) oligophagous and 13 (59%) had just only one host plant species recorded. the most abundant species of moths exhibitted two reproductives periods in the year, predominantly in winter and autumn. abiotic factors, such as strong insolation during spring and summer in the open scrub vegetation of restinga, may be very important in producing this temporal pattern of insect reproduction, but we cannot neglect biotic factors like natural enemies.

Abstract: OBJETIVO: Verificar a rela o da concentra o de chumbo no esmalte de dentes decíduos com a presen a de defeitos de esmalte e sua rela o com cárie dental em pré-escolares. MéTODOS: A amostra foi de 329 crian as de pré-escolas municipais de uma área próxima de indústrias (N=132) e outra n o industrial (N=197) da cidade de Piracicaba, Estado de S o Paulo. Essa amostra pertencente a um estudo inicial realizado entre 2000 e 2001 no qual o chumbo foi analisado por meio de biópsia de esmalte. Foram realizados exames clínicos bucais para verifica o da prevalência de defeitos de esmalte (Developmental Defects of Enamel Index - DDE, da Federa o Dentária Internacional - FDI) e cárie (índice ceos, Organiza o Mundial da Saúde), em ambas regi es. Foram utilizados teste de qui-quadrado e cálculo do risco relativo ao nível de significancia de 5%, considerando cada regi o separadamente. RESULTADOS: Houve maior propor o de crian as com cárie entre aquelas com maiores concentra es de chumbo nos decíduos na regi o n o industrial (p=0,02), o que n o se observou na regi o industrial (p=0,89). Houve risco relativo (RR) aumentado de cárie nas crian as da regi o n o industrial o que n o foi verificado nas crian as da regi o industrial. N o se observou rela o entre a presen a de chumbo e os defeitos de esmalte. CONCLUS ES: N o foram encontados dados que evidenciassem a rela o entre concentra o de chumbo e defeitos no esmalte em nenhuma das regi es pesquisadas. N o foi encontrada rela o entre chumbo e cárie na regi o industrial, ressaltando a necessidade de mais estudos dessas rela es.

Discursos Fotográficos , 2007,
Abstract: This article addresses the intertextualities of photography and cinema, the literature, the engraving and Internet. It seeks to organize the photograph starting from its relations and hybridism with other arts and media. When we understand the intertextual aspect of photography in various moments of its history, we move forward in understanding its intersection with science, the arts and media, existing relations since the origins of photography with impact in current times. Este artigo aborda intertextualidades da fotografia com o cinema, a literatura, a gravura e a internet. Busca-se organizar o pensamento fotográfico a partir de suas rela es e hibridismos com outras artes e meios de comunica o. Ao entendermos o aspecto intertextual da fotografia em vários momentos de sua história caminhamos no entendimento de sua intersec o com a ciência, as artes e os meios de comunica o, rela es presentes desde a origem da fotografia e com desdobramentos nos dias atuais.

Abstract: Oral mucositis is a result of toxicity and one of the most common side effects of radiotherapy and chemotherapy in cancer treatment and in hematopoietic stem cell transplantation. Clinically these changes are characterized by epithelial atrophy, edema, erythema and the appearance of ulcerations that can affect the entire oral mucosa, causing pain and discomfort, impairing speech, and swallowing food. In addition to the major symptoms, the ulcers increase the risk of local and systemic infection, compromising function and interfering with oral antineoplastic treatment and may lead to it being discontinued. The diagnosis, prevention and therapeutic strategies in providing support in cases of oral mucositis are the dentist’s responsibility. Through critical analysis of literature, the aim of this article is to present oral mucositis, its pathogenesis, clinical features and treatments offered today to address or control the condition, highlighting the importance of dentists’ role in its management.
Electrochemical impedance spectroscopy of dodecylsulphate doped polypyrrole films in the dark and under illumination
Martini, Milena;Matencio, Tullio;Alonso-Vante, Nicolás;De Paoli, Marco-Aurélio;
Journal of the Brazilian Chemical Society , 2000, DOI: 10.1590/S0103-50532000000100010
Abstract: the morphology, thickness, oxidation and illumination effects in dodecylsulphate doped polypyrrole films can be qualitatively observed by eis and consist in variations of interfacial and bulk resistances and capacitances of a proposed equivalent circuit. the circuit well with the measured spectra of films obtained with 190 mc cm-2 of synthesis charge density. for thinner films the calculated values observed by electrochemical impedance spectroscopy (eis) deviate probably due to the absence of diffusion effects. the oxidation of the films diminishes the total impedance over the entire frequency range. the morphology effects are also observed in the entire spectra. the illumination effects are reversible and are observed as expected only in the reduced form of the polymer. the illumination reduces the internal resistance and the space-charge capacitance and increases the charge transfer resistance and the double layer capacitance.
