Abstract: Neste trabalho s o apresentados os resultados relativos à proposta para a amplia o do programa de coleta seletiva no município de S o Jorge do Ivaí, estado do Paraná, Brasil. A metodologia contempla aplica o de questionário, visita ao barrac o de triagem, caracteriza o gravimétrica de resíduos e confec o de mapa de zoneamento da coleta seletiva. A coleta seletiva atual foi implementada pela prefeitura municipal por meio de um projeto piloto na regi o central do município. Estima-se a coleta de 1,12 t mensal de resíduos com a participa o de 30% da popula o do município. No entanto, as estimativas aqui realizadas indicam a gera o diária de 6,0 t de resíduos sólidos urbanos com 20% (1,18 t diário) passíveis de reaproveitamento e reciclagem. Desse modo, se justifica a amplia o da coleta seletiva no município e as necessidades básicas para a realiza o dessa implanta o s o aqui descritas. = This paper presents the results for the proposed to expand the program of selective collection in the S o Jorge Ivaí, Paraná, Brazil. The methodology involved questionnaires, visits to the shed screening, characterization of wastes and gravimetric preparation of zoning map of the collection. The current selective collection was implemented by the municipal government through a pilot project in the central city. It is estimated to collect 1.12 tons per month of waste with theparticipation of 30% of the population of the municipality. However, the estimates made here indicate the daily generation of 6.0 tons of waste with 20% (1.18 t/day) capable of reusing and recycling. Thus, there is justification for expanding the collection at the county and the basic needs for the completion of this deployment are described here.

Abstract: The action human, especially associated to the population occupation in a disordered way, it has been carting several environmental problems to the urban creek of Boa Vista, taking the public managers develop her several action types in those areas, as for instance, the canalization of passages of some creeks. Inside of that context, the present work proposes the approach of the canalization of the Mirandinha creek, detaching their main impacts for the society and the environment. As it can be observed, the Mirandinha creek already possesses significant part of his channeled passage, what provoked the complete modification of the morphology of the bed of the channel and also the alteration of the margins of the creek in the channeled area, descaracterizando totally the natural configuration of the same.

Abstract: background: lichen planus is a relatively common chronic inflammatory disease affecting skin and mucous membranes, separately or together. it frequently involves the oral cavity, with or without concomitant cutaneous compromise. microscopically, while skin presents well characteristic aspects, oral mucosa can present variations related to local characteristics of the mucosa in the oral cavity. objectives: to compare histopathological alterations of oral lichen planus and cutaneous lichen planus with the study of the inflammatory infiltrate components. methods: 59 biopsies (29 of olp and 30 of clp), formalin-fixed, paraffin-embedded were studied. semi-quantitative analysis of both epidermal and dermal alterations was performed using the hematoxylin-eosin and periodic acid-schiff stains. results: for clp the classic aspects of orthokeratosis, wedge shaped hypergranulosis and saw tooth rete ridges were observed. such aspects differ from those of olp in which orthokeratosis and thickened granular layer happen less frequently; instead, acquisition of those layers is observed in places where they are usually absent. basal cell vacuolar alteration and effacement of the epithelium-conjunctive limit prevailed in both locations (skin and oral mucosa) and lymphocytes and histiocytes were the inflammatory cells present in all cases. conclusions: classic alterations as compact orthokeratosis, wedge shaped hypergranulosis, saw tooth rete ridges acanthosis and basal cell vacuolar alteration associates to lymphocytes in superficial band-like pattern are diagnostic of clp. however, for olp, the particular own characteristics of oral mucosa in the biopsied place should be considered; also, subtler alterations of horny (light orthokeratosis) and granular (presence where it is usually absent) layers should be valued . wedge shape pattern of hypergranulosis is rarely seen in olp. saw tooth rete ridges acanthosis is not frequently seen in olp, however, basal cell vacuolar alteration is a

Abstract: oral hairy leukoplakia (ohl) is one of the most common oral manifestations of aids, with diagnostic and prognostic value. ohl is associated to the epstein-barr virus and presents clinical and histological defined characteristics. there have already been reports about a subclinical stage of ohl, although they lacked histopathologic characterization. the present study had the aim to describe the histopathological characteristics of subclinical hairy leukoplakia, as well as to carry out a comparative analysis between clinical and subclinical ohl. for that, 11 cases were analyzed - 5 biopsies from patients who presented with the lesion and 6 samples from the borders of tongues obtained in necropsies. the histopathological findings in subclinical ohl were: absence of parakeratosis and papillomatosis, mild acanthosis, ballooning cells and nuclear alterations. in situ hybridization and immunostaining were positive for ebv in the nuclear alterations identified in the histophatological analysis. based on the identification of ebv in the nuclear alterations, it was possible to conclude that subclinical ohl, similarly to the clinical lesion, presents histopathological features that are specific and sufficient to establish the definitive diagnosis, regardless of the identification of the virus.

Abstract: Geological maps and stratigraphic charts of the Amazon and Solim es sedimentary basins were reviewed, emphasizing the formations Alter do Ch o, I á and Solim es, the largest reserves of fresh groundwater in these basins. The lack of information on these formations was minimized by sample probe and stratigraphic profiles of construction, lithological and geophysical water and oil wells, obtained in the Base Operacional Geólogo Pedro de Moura, Urucu region, about 650 km southwest of Manaus (AM). In the Amazon Basin, the Aquifer System Alter do Ch o is characterized by unconfined and confined aquifers, with transmissivity between 1.5 and 9.1 x 10-3 m2/s, indicated for public supply. In the Solim es Basin, this system is confined by Aquiclude Solim es, recovered by the I-Solim es Aquifers. The reserve is estimated as 33,000 km3. The Aquifer System I á-Solim es, in Urucu, is unconfined-confined, with two aquifers hydraulically connected: the superficial, with top and bottom at depths near 20 and 70 m, respectively; and the deeper, between 50 and 120 m. With an outcrop area of 948,600 km2 in the Solim es Basin, the reservation of this system was estimated as 7,200 km3, less expressive than the Aquifer System Alter do Ch o. The average hydrodynamic parameters were: T = 3 x 10-3 m2/s, S = 5 x 10-4 and K = 1 x 10-4 m/s, orders of magnitudes similar to those found in the aquifer Alter do Ch o. Assessing the interrelationships and potential of these two regional aquifers sought to contribute to the hydrogeological knowledge in the Amazon Basin region, where researches on groundwater are still incipient.

Abstract: INTRODU O: Líquen plano é uma doen a inflamatória cr nica relativamente comum que acomete pele e membranas mucosas, separadamente ou em combina o. Freqüentemente envolve a cavidade oral, com ou sem comprometimento cutaneo concomitante. Microscopicamente, enquanto a pele apresenta aspectos bastantes característicos, a mucosa oral pode apresentar varia es relacionadas às características locais da mucosa na cavidade oral. OBJETIVOS: Comparar as altera es histopatológicas do líquen plano oral (LPO) com as do líquen plano cutaneo (LPC), estudando os componentes do infiltrado inflamatório. MATERIAL E MéTODOS: 59 biópsias (29 de LPO e 30 de LPC ) fixadas em formol e incluídas em blocos de parafina. Foi realizada análise semiquantitativa das altera es epidérmicas e dérmicas utilizando-se as colora es de hematoxilina-eosina e ácido periódico Schiff. RESULTADOS: No LPC foram observados os aspectos clássicos de ortoceratose, hipergranulose em cunha e acantose em dente de serra. Tais aspectos diferem do LPO, no qual ortoceratose e camada granulosa espessada ocorrem com menos freqüência, observando-se aquisi o destas camadas nos locais onde est o normalmente ausentes. Vacuoliza o e apagamento do limite epitélio-conjuntivo predominaram nas duas localiza es (pele e mucosa oral), e linfócitos e histiócitos foram as células inflamatórias presentes em todos os casos. CONCLUS ES: O conjunto de altera es clássicas como ortoceratose compacta, hipergranulose em cunha, acantose em dente de serra e vacuoliza o da basal, associadas a linfócitos em faixa superficial é diagnóstico de LPC. Para o LPO, no entanto, devem ser consideradas as características próprias da mucosa no local biopsiado, devendo ser valorizadas altera es mais sutis da camada córnea - leve ortoceratose - e aparecimento da camada granulosa em locais onde normalmente é ausente. Aspecto em cunha da hipergranulose é de ocorrência rara no LPO. Acantose em dente de serra é achado pouco freqüente no LPO, porém vacuoliza o basal está sempre presente associada a infiltrado linfocitário em faixa; plasmócitos podem acompanhar linfócitos no LPO, mas est o ausentes do LPC.

Abstract: the thymus is a central lymphoid organ, in wich t cell precursors differentiale and generate most of the so-called t cell reprtoire. along with a variety of acute infectious diseases, we and others determined important changes in both microenvironmental and lymphoid compartments of the organ. for example, one major and common feature observed in acute viral, bacterial and parasitic diseases, is a depletion of cortical thymocytes, mostly those bearing the cd4-cd8 double positive phenotype. this occurs simmultaneously to the relative enrichment in medullary cd4 or cd8 single positive cells, expressing high densities of the cd3 complex. additionally we noticed a variety of changes in the thymic microenvironment (and particularly is epithelial component), comprising abnormal location of thymic epithelial cell subsets as well has a denser ia-bearing cellular network. moreover, the extracellular matrix network was altered with an intralobular increase of basement membrane proteins that positively correlated with the degree of thymocyte death. lastly, anti-thymic cell antibodies were detected in both human and animal models of infectious diseases, and in some of them a phenomenon of molecular mimicry could be evidenced. taken together, the data receiwed herein clearly show that the thymus should be regarded as a target in infectious diseases.

Abstract: background: carcinogenesis is a multifactorial process and inactivation of p53 protein is a genetic change commonly observed in oral squamous cell carcinomas (oscc). objectives: to analyze and compare the expression of p53 protein through antibodies do-7 and pab-240 in oscc samples located in the oral cavity and lower lip. material and methods: forty cases of oscc were selected and divided into oral cavity and lower lip groups (20 cases each). immunohistochemical technique was performed using antibodies do-7 and pab-240. quantification of the cases was performed through digital image analysis and underwent specific statistical treatments. results: expression of p53 protein was verified with do-7 antibody in 13 cases (65%) of oral cavity carcinomas and in 19 cases (95%) of lower lip carcinoma. pab-240 positivity was detected in 9 cases (45%) of oral cavity lesions and in 15 cases (75%) located in the lower lip. according to mann-whitney test, there were no statistically significant differences between the expressions of p53 protein in both groups, regardless of the antibody used. according to wilcoxon test, there were statistically significant differences between the expression of do-7 antibody and pab-240 in each of the analyzed groups (p-value = 0.013; lower lip p-value = 0.016 - oral cavity). conclusions: the expression of p53 protein was observed both in the oral cavity and lip oscc, which suggests the occurrence of mutations in tp53 gene. the quantitative differences between the antibodies studied, regardless of the site of the lesions, reflect different specificity between clones do-7 and pab-240. further studies are required to establish the best antibody for p53 protein in oral squamous cell carcinomas.
