Two new troglobitic species of Scleropactidae (Crustacea: Isopoda: Oniscidea) from Pará, Brazil

The South America Scleropactidae includes 53 nominal species distributed in 14 genera. In Brazil, there are 16 species recorded in the north and southeast regions. Here, two new species of Scleropactidae are described based on material collected in caves in the state of Pará, both troglobitic and allocated in the genus Circoniscus. Circoniscus buckupi sp. nov. can be distinguished from its congeners by the long second article of antennal flagellum, inner endite of maxillula with a small hook-like spine at the apex, a long dactylar organ with pectinate apex conferring a knife-shaped appearance and the absence of schisma in adults. Circoniscus carajasensis sp. nov. can be distinguished from Circoniscus buckupi sp. nov. by the presence of schisma on pereionite 1 in adults and dactylar organ with a fringe appearance

Redescription of the fish-parasitic isopod Cymothoa ianuarii Schioedte & Meinert, 1884 and further records of C. excisa Perty, 1833 and C. oestrum (Linnaeus, 1758) (Isopoda: Cymothoida: Cymothoidae) from Brazil

Cymothoa ianuarii Schioedte & Meinert, 1884 is rediscovered almost 136 years after its original description and redescribed from specimens collected in the state of São Paulo. This species is mainly characterized by adult females with cephalon with conspicuous eyes and not deeply immersed in pereonite 1, pereonites 5-6 much wider than 4, pleotelson twice as wide as long and pleopods 1-5 decreasing in size; Cymothoa excisa Perty, 1833 and C. oestrum (Linnaeus, 1758) are recorded from the state of Bahia. Illustrations and an updated distribution map for these species in Brazil are provided

Novas espécies e novos registros de isópodes terrestres (Crustacea, Isopoda, Oniscidea) do Brasil

A large collection of terrestrial isopods from diff erent Brazilian regions was examined. Two new species of Amazoniscus Lemos de Castro, 1967 (Scleropactidae) are described: A. zimmeri Campos-Filho, Montesanto & Araujo sp. nov. from the state of Pará and A. schmidti Campos-Filho, Montesanto & Taiti sp. nov. from the state of Minas Gerais. Pseudotyphloscia alba (Dollfus, 1898) (Philosciidae) is fi rstly recorded from Brazil. The systematic position of Venezillo tuberosus (Budde-Lund, 1904) is discussed and transferred to Ctenorillo Verhoeff , 1942.

Marsupial extension in terrestrial isopods (Crustacea, Isopoda, Oniscidea)

In Oniscidea, the marsupium is a ventral pouch where the offspring develop independently of an external water source. The marsupium is formed by five pairs of overlapping oostegites that develop in the females during their reproductive period. In this study, ovigerous females of 35 species were dissected, their oostegites were extracted, and the intra-marsupial offspring were counted. Two marsupium forms were recognized: distended, in which the oostegites protrude distally in relation to the sternites; and non-distended, in which the oostegites are parallel to the sixth and seventh sternites. Armadillidium nasatum, A. vulgare, Pudeoniscus birabeni, Circoniscus gaigei and Cubaris murina, conglobating species with a non-distended marsupium, and Neotroponiscus daguerri and N. carolii, non-conglobating species with a distended marsupium, have a concavity on the ventral floor of the 6th and 7th pereionites, here called the marsupial extension. This is the first record of a marsupial extension which extends beyond the area formed by the oostegites in Oniscidea

A new species of Parastacus Huxley, 1879 (Crustacea, Decapoda, Parastacidae) from a swamp forest sothern Brazil

In this contribution we describe a new species of burrowing crayfi sh of the genus Parastacus Huxley, 1879 from a swamp forest in southern Brazil and determine its conservation status. Th e distinction of the new species is based on morphology and the mitochondrial DNA marker 16S rRNA. Th e extinction risk was assessed according to the sub-criterion B1 of IUCN that estimates the Extent of Occurrence (EOO). Parastacus tuerkayi sp. nov. is morphologically distinguishable from all species of Parastacus by having three lines of verrucous tubercles on the dorsomesial margin of the cheliped propodus and a suborbital angle exceeding 90°. Th e EOO comprises 647,674 km², and the species is classifi ed as “endangered”. Phylogenetic relationships indicate the distinct position of this new species in relation to the already described species

Os efeitos do termo de ajustamento de conduta sobre a persecução penal nos crimes contra o meio-ambiente

O presente artigo foi desenvolvido a partir da discussãosobre a tutela penal do bem jurídico meio ambiente. Ao analisara função da pena e os princípios norteadores do Direito Penalfica claro que estes são deixados de lado quando se trata da proteçãoambiental. O Termo de Ajustamento de Conduta - TAC - tantocomo título executivo extrajudicial quanto como acordo firmadoentre o órgão estatal e o ajustante, de modo a acelerar o processodecisório e de resolução de contendas, uma vez que a recuperação/preservação do meio ambiente tem caráter de urgência e não suportaa mora típica do processo de cognição tradicional, mostra-secomo resposta a um Direito Penal repressivo e vingativo, que nãotem sido eficiente na proteção dos bens jurídicos difusos. Destaforma procura-se, com o uso de metodologia jurídico-teórica e doraciocínio dedutivo, através de pesquisa bibliográfica e documental,discutir a necessidade da persecução criminal após a aplicaçãoe, principalmente, o cumprimento integral do TAC, pois enxergamos o princípio da intervenção mínima como essencial ao direitopenal moderno, sendo caminho para se atingir a verdadeira realizaçãodo direito penal como ultima ratio. Desta forma chegamosà conclusão de que tendo sido assinado o Termo de Ajustamentode Conduta antes do oferecimento da denúncia não há justa causapara a ação penal, devendo esta ser extinta

Multipolar mitosis and aneuploidy after chrysotile treatment: a consequence of abscission failure and cytokinesis regression

Chrysotile, like other types of asbestos, has been associated with mesothelioma, lung cancer and asbestosis. However, the cellular abnormalities induced by these fibers involved in cancer development have not been elucidated yet. Previous works show that chrysotile fibers induce features of cancer cells, such as aneuploidy, multinucleation and multipolar mitosis. In the present study, normal and cancer derived human cell lines were treated with chrysotile and the cellular and molecular mechanisms related to generation of aneuploid cells was elucidated. The first alteration observed was cytokinesis regression, the main cause of multinucleated cells formation and centrosome amplification. The multinucleated cells formed after cytokinesis regression were able to progress through cell cycle and generated aneuploid cells after abnormal mitosis. To understand the process of cytokinesis regression, localization of cytokinetic proteins was investigated. It was observed mislocalization of Anillin, Aurora B, Septin 9 and Alix in the intercellular bridge, and no determination of secondary constriction and abscission sites. Fiber treatment also led to overexpression of genes related to cancer, cytokinesis and cell cycle. The results show that chrysotile fibers induce cellular and molecular alterations in normal and tumor cells that have been related to cancer initiation and progression, and that tetraploidization and aneuploid cell formation are striking events after fiber internalization, which could generate a favorable context to cancer development

Radio-telemetry techniques in the study of displacement of freshwater anomurans

In an ecological context, information on the movement and activity is important for understanding the requirements of habitat, resource usage patterns and the potential of interspecific interactions. The aim of this study was to examine the displacement pattern on daily activity and occupancy of substrates by Aegla manuinflata using radio-telemetry technique on field on Southern Brazil. Four adult males were monitored during nine days. The aeglids showed a significantly greater displacement toward upstream than downstream. Aegla manuinflata individuals showed higher displacement activity during the night period. Although activity was not constant: the animals spent one or more days without displacement. All aeglids showed locomotion activity concentrated between 11:43 p.m. and 02:25 a.m., although it was not restrict to sunset period and night. Individuals showed specific occupation of different types of substrate, but a pattern in the occupation of substrates as a function of the photoperiod was not observed. In this study, using a new technique for tracking aeglids, it was concluded that A. manuinflata is capable of actively dislocate throughout the stream, either toward upstream and downstream, passing through obstacles which may represent ability of re-colonization. The animals are more active during the night period, probably a strategy to avoid predators that are active during the day; the selection of substrate is not associated to sediment texture

Estado nutricional de crianças com cardiopatias congênitas

OBJECTIVE: to characterize nutritional status and variables that predict nutritional changes in children with congenital heart disease. METHOD: a cross-sectional study undertaken in two health institutions between January and June 2009, using a questionnaire with questions about nutrition, applied to 132 children under two years of age who had congenital heart disease. Children who had additional serious illnesses were excluded. RESULT: the predominant percentile values and Z scores were concentrated within the range of normal levels. The Z scores, however, presented negative variations with a deviation to the left. In the analysis of predictive factors, the occurrence of immediate and acute malnutrition was related to a decrease in skinfold thickness (decrease in subscapular skinfold thickness, while immediate malnutrition was related to a high Apgar score. Chronic malnutrition was related to female children with higher ages. CONCLUSION: it is evidenced that it is necessary to carry out nutritional strategies which improve prognosis, so as to widen the nursing care directed at these children.OBJETIVO: caracterizar el estado nutricional y verificar variables que predicen alteraciones nutricionales en niños portadoras de cardiopatías.
