Journal of Tropical Medicine , 2012, DOI: 10.1155/2012/858657
Abstract: The aim of this study was to identify potential blood feeding sources of L. (L.) longipalpis specimens from populations in Northeastern Brazil, endemic areas of American Visceral Leishmaniasis (AVL) and its correlation with the transmission of L. (L.) i. chagasi. The ELISA technique was applied using bird, dog, goat, opossum, equine, feline, human, sheep, and rodent antisera to analyze 609 females, resulting in an overall positivity of 60%. In all municipalities, females showed higher positivity for bird followed by dog antiserum and sand fly specimens were also positive for equine, feline, human, sheep, goat, opossum, and rodent antisera. The finding for 17 combinations of two or three types of blood in some females corroborates the opportunistic habit of this sand fly species. The results demonstrating the association between L. (L.) longipalpis and opossum suggest the need for further evaluation of the real role of this synanthropic mammal in the eco-epidemiology of AVL. 1. Introduction American visceral leishmaniasis (AVL) is a serious public health problem in Brazil and presents a new epidemiological profile associated with domestic environments and, in this context, Lutzomyia (Lutzomyia) longipalpis is important considering its capacity to adapt to a wide range of impacted habitats, in addition to its sylvatic origin [1–3]. The enzyme immunoassay (ELISA) has been used to identify the feeding habits of L. (L.) longipalpis [4–6]. In light of this, studies related to feeding habits of sand fly vector L. (L.) longipalpis could contribute to a better understanding of eco-epidemiology of AVL, discussing its close association with Leishmania (Leishmania) infantum chagasi reservoirs. Currently, Northeastern Brazil accounts for about 47% of human cases for AVL exhibiting both epidemiological profiles, rural and urban, with highest incidences of the disease according to the Brazilian National Leishmaniases Program (NLP) [1]. The aim of this study was to identify potential blood meal sources for L. (L.) longipalpis from some Northeastern Brazil endemic municipalities. 2. Materials and Methods 2.1. Sand Fly Precedence Sand flies were collected from the municipalities of Jequié (State of Bahia, BA), Sobral and Massapê (State of Ceará, CE), and Teresina (State of Piauí, PI). These municipalities were selected based on their levels and profiles of AVL transmission according to NLP: Teresina, urban and intense transmission; Sobral, rural and intense transmission; Jequié, rural and moderate transmission, and Massapê, rural and sporadic transmission [1].

Abstract: the precipitin test was applied to identify the blood meal sources of lutzomyia intermedia, collected in two distinct habitats: inside houses and in the peridomicile, in mesquita, rio de janeiro state, brazil, a transmission area of leishmania (v.) braziliensis. the following antisera were tested: human, avian, equine, rodent, and opossum. from a total of 370 females analyzed, 128 specimens from the domicile and 59 from the peridomicile reacted with specific antisera. the anthropophily of l. intermedia was confirmed in both habitats; likewise, the feeding of this sand fly species on domestic animals, observed in previous entomological surveys, was confirmed by the strong reactivity with avian, canine, and equine antisera. however, feeding on rodents, mammals frequently found inside and around houses, represents further evidence related to the vector competence of l. intermedia, since synanthropic and sylvatic rodents have been considered a putative reservoir of l. (v.) braziliensis.

Abstract: A crescente presen a de patógenos no ambiente aquático representa um dos maiores problemas de saúde pública decorrentes em grande escala de deficiências inerentes ao saneamento. A análise de risco baseou-se no método WHO (2001), com adapta es propostas por DONOVANet al. (2008), concatenando aplica es com dados sanitários da malha hídricaque desemboca na Baía de Sepetiba. O risco anual para o desenvolvimento de gastrenterites na popula o que usufruir dessa Baía é de 0,63577, que comparados aos valores da USEPA e WHO,significa ser aproximadamente 63 vezes e meia maior a probabilidade de desenvolver gastrenterites devido ao uso recreacional das águas da Baía de Sepetiba. A avalia o de risco microbiológico traz informa es sobre o risco de doen as a que est o expostas as popula es e com base nessas informa es, medidas de controle e prote o podem ser propostas para minimizar agravos significativos a popula o.

International Journal of Morphology , 2007,
Abstract: The ischiatic artery classically described as a branch of the inferior gluteal artery, is a long and thin vessel that is related to the ischiatic nerve. In a dissection was observed that this artery emerges from the internal pudendal artery with a caliber larger than the ones described in the literature. The knowledge of anatomical variations is important to the surgeons, radiologists and anatomists La arteria isquiática se describe clásicamente como una rama de la arteria glútea inferior, es un vaso largo y delgado que se relaciona con el nervio isquiático. En una disección se observó que esta arteria surge de la arteria pudenda interna con un calibre más grande que lo descrito en la literatura. El conocimiento de variaciones anatómicas es importante para los cirujanos, radiólogos y anatomistas

Abstract: Em psicologia, encontramos uma pluralidade de abordagens teóricas que d o origem a diferentes tipos de práticas clínicas. Nossa pergunta inicial é se haveria um conceito ou no o em psicologia que nos permitisse discorrer a cerca da prática clínica independente do referencial teórico adotado, já que cada teoria extrai suas técnicas e sua ética do pressuposto filosófico no qual se assenta. Como n o poderia deixar de ocorrer, esbarramos na quest o da ética, tendo sua pretens o de universalidade contrastada com a clínica do “um-a-um” vivenciada na experiência cotidiana. In psychology we found a plurality of theoretical approaches that originated different types of clinical practices. Our initial question was if there would be a concept or notion in psychology that allowed to discourse about the independent clinical practice of the adopted theoretical reference, since, each theory extracts its techniques and ethics from philosophical presumption on which it is set. Though we encounter the question of the ethics, once its universal intent contrasts with the daily “one-to-one” clinic experience.

A SENTEN A LIMINAR DO ARTIGO 285-A DO CPC E A CELERIDADE PROCESSUAL: UMA ABORDAGEM à LUZ DOS PRINCíPIOS DA ISONOMIA, DO ACESSO à JUSTI A E DO DEVIDO PROCESSO LEGAL
Gustavo Martins dos Santos
Revista da SJRJ , 2010,
Abstract: Busca-se comprovar a constitucionalidade do instituto da senten a liminar de improcedência de que trata o art. 285-A do CPC, instituído pela Lei no 11.277/2006. Embora determinada corrente aponte ofensa aos princípios do devido processo legal, contraditório, ampla defesa, isonomia e acesso à justi a, a jurisprudência pátria tem decidido no sentido contrário. Ainda que se empreste peso equivalente a cada uma dessas correntes, prevalece a conclus o pela constitucionalidade da norma, por ser ela instrumento de realiza o do princípio constitucional da celeridade processual e da razoável dura o do processo, e porque as garantias constitucionais tidas por ofendidas, por n o terem caráter absoluto, podem sofrer limita es, especialmente para harmonizar o conjunto dos princípios constitucionais envolvidos, dando efetividade a todos eles.
