In each experiment there were used three domestic pigs, Sus scrofa L. (Suidae), weighting approximately 43 kg each, and taken alive until the collection place to be killed by a gun shot in the frontal region of its head, and placed in three metallic jails, that were partially submerged in three different areas along the Barro Branco stream, keeping approximately 90m distance from eacho ther area. The collected taxons were 35.655 belonging to five orders, 20 families, 40 morphotypes and 56 species. Among the blowflies, Chrysomya albiceps (Wiedeman, 1830) was the most abundant species with 10,880 individuals, while the specie Peckia (Pantonella) smarti (Lopes, 1941) belonging to Sarcophagidae family presented 679 specimens. Six stages were completed during the decomposition of the carcass: the first stage was the SF (submerged fresh), adapted to PSF (partially submerged fresh), having the average decomposition cycle as of 19.5 days in the Less Rainy period of 2008 and 2009 and 24.5 days in the Rainy season of 2008 and 2009. The early floating, floating decay and bloated deterioration stages, presented more Diptera abundance. The rearing of eggs and larvae yielded the following species: Chrysomya albiceps (Wiedemann, 1830), Hemilucilia segmentaria (Fabricius, 1805), H. semidiaphana (Rondani, 1850), Chrysomya putoria (Wiedemann, 1830), Lucilia eximia (Wiedemann, 1819), Paralucilia paraensis (Mello, 1969), Paralucilia fulvinota (Bigot, 1877), Paralucilia pseudolyrcea (Mello, 1969) (Calliphoridae); Peckia (Pattonella) smarti (Lopes, 1941), Peckia (Pattonella) pallidipilosa (Curran & Walley, 1934), Peckia (Pattonella) intermutans (Walker, 1861) and Peckia (Peckia) chrysostoma (Wiedemann, 1830) (Sarcophagidae). Larvae Calliphoridae and Sarcophagidae were the major consumers of pig, some adults which the biology were studied in the region, shown favorable to be used as forensic indicator. In fourteen species of adult Calliphoridae only 9 (64%) were collected in the immature form, and in fifteen of Sarcophagidae, only 4 (26%), demonstrating the importance of studying the biology of the larvae of these species. Among the aquatic immature, only chironomids were collected and raised to adulthood and found feeding on the soft parts of the pig body tissue using the bones as shelter. According to the results obtained from immature created, it is possible to estimate the overflow time of a corpse involving river systems. These results may indicate that in both periods (less and rainy and seasons) differed only in relation to precipitation, possibly due to the regularity of high temperature and relative humidity, characteristic in the Amazon region. The climatic periods have not come to negatively influence the composition and abundance of species. Likewise, there was no influence of temperature and pH of the water on the decomposition of body partially submerged in the different periods studied. / Para determinar as espécies de insetos decompositores de suínos parcialmente submersos em um igarapé de terra firme, foram realizados quatro experimentos, dois a cada período do ano de 2008 e de 2009 (período menos Chuvoso e Chuvoso) na Reserva Florestal Ducke, Manaus – Amazonas. Foram analisados aspectos referentes à sucessão, riqueza, abundância relativa e os estágios de decomposição do suíno. Em cada experimento foram utilizados três suínos domésticos Sus scrofa (Suidae) pesando aproximadamente 43 kg e levados vivos até o local de coleta para serem abatidos com um disparo de arma de fogo na região frontal da cabeça, e colocados em três gaiolas de ferro, que ficaram parcialmente submersas em três diferentes pontos ao longo do igarapé Barro Branco, distantes aproximadamente 90 m uma da outra. Os táxons coletados totalizaram 35.655 pertencentes a cinco ordens, 22 famílias, 44 morfótipos e 62 espécies. Em Calliphoridae Chrysomya albiceps (Wiedeman, 1830) foi a mais abundante com 10.880 indivíduos, enquanto que a espécie Peckia (Pantonella) smarti (Lopes, 1941) da família Sarcophagidae apresentou 679 espécimes. Seis estágios de decomposição em cadáver de suínos se completaram, sendo o primeiro estágio FS (Fresco Submerso), adaptado para FPS (Fresco parcialmente Submerso), sendo a decomposição total em média 19,5 dias no período menos Chuvoso de 2008 e 2009 e 24,5 dias no período Chuvoso de 2008 e 2009. Os estágios de flutuação inicial, deterioração de flutuação e deterioração inchada apresentaram maior abundância de Diptera. Da criação de ovos e larvas onde se destacaram as espécies da família Calliphoridae: Chrysomya albiceps (Wiedmann,1830), Hemilucilia segmentaria (Fabricius, 1805), H. semidiaphana (Rondani, 1850), Chrysomya putoria (Wiedemann, 1830), Lucilia eximia(Wiedemann, 1819), Paralucilia paraensis (Mello, 1969), Paralucilia fulvinota (Bigot, 1877), Paralucilia pseudolyrcea (Mello, 1969). Espécies da família Sarcophagidae: Peckia (Pattonella) smarti (Lopes, 1941), Peckia (Pattonella) pallidipilosa (Curran & Walley, 1934), Peckia (Pattonella) intermutans (Walker, 1861) e Peckia (Peckia) chrysostoma (Wiedemann, 1830). As larvas de Calliphoridae e Sarcophagidae foram as principais consumidoras do suíno, alguns adultos têm sua biologia estudada na região e mostraram serem propícias para serem utilizadas como indicadoras forenses. Das quartoze espécies adultas de Calliphoridae, nove (64%) foram coletadas na forma imatura, e das quinze de Sarcophagidae, apenas quatro (26%), demonstrando a importância de estudar a biologia das larvas dessas espécies. Entre os imaturos aquáticos, apenas os Chironomidae foram coletados e criados até a fase adulta e encontrados alimentando-se das partes moles do tecido corporal do suíno, utilizando os ossos como abrigo. De acordo com os resultados obtidos a partir dos imaturos criados é possível fazer uma estimativa do tempo de submersão de um cadáver que envolva sistemas lóticos. Tais resultados podem indicar que nos dois períodos (menos chuvoso e chuvoso) diferiram somente em relação a precipitação, possivelmente em função da regularidade da alta temperatura e umidade relativa característica na região amazônica. Não houve diferença na abudância e composição das espécies entre os períodos chuvoso e menos chuvoso. Da mesma forma não houve influência da temperatura e pH da água sobre a decomposição do cadáver parcialmente submerso nos diferentes períodos estudados.

We describe here the topotypic series of Conohyus olujici n. sp. from the Croatian locality of Lučane. This sample was originally collected by local lignite miners in the 1930's, who conveyed the sample to the parish's Franciscan monk Dr. Josip Olujić. The Luč ane Conohyus sample includes seven lower jaws and jaw fragments; no upper cheek teeth have yet been recovered. Our use of bivariate statistics, log10 ratio diagrams and a cladistic analysis all reveal that C. olujici n. sp. is the most primitive member of the Conohyus clade. The analyses reveal that: of the sample considered, only two species are referable to Parachleuastochoerus, P. sp. and P. crusafonti; Parachleuastochoerus is the sister-taxon to Conohyus; Conohyus is a clade, and C. olujici n. sp. is the sister-taxon of the C. steinheimensis-C. simorrensis and C. sindiensis clades. Conohyus olujici n. sp. would appear to have occurred at a time when the genus enjoyed a relatively continuous geographic range that extended from southern Europe to South Asia. Conohyus olujici n. sp. was evidently adapted to swamp forest habitats. Its paleodiet, as evidenced by its thick molar enamel and labiolingually expanded posterior premolars, likely included hard object frugivory.

The epithelial cell of the kidney proximal convoluted tubule, like that of the small intestine, consists of two distinct plasma membrane surfaces referred to as the brush border, or luminal surface, and the basal-lateral, or contraluminal surface. Once isolated, membrane vesicles formed from the kidney cell can serve as models for the study of heavy metal mephrotoxin interaction with the two different plasma membrane surfaces. For ideal comparison between the two membranes, the isolation procedure should be identical for both. This has been accomplished by other investigators using differential centrifugation followed by free-flow electrophoresis or sucrose density centrifugation. Utilizing the self-forming gradient capabilities of Percoll, we have developed a less cumbersome procedure to effect simultaneous isolation of brush border and basal-lateral membrane vesicles. Brush border membrane vesicles isolated by this procedure exhibited 8 to 13-fold enrichment in marker enzyme activity but appeared to have impaired glucose uptake activity. Since the Percoll-prepared vesicles seemed unsuitable for uptake studies, brush border membrane vesicles isolated by a differential precipitation method were used to investigate the effect of cadmium on glucose uptake. Of the concentrations of cadmium tested, 0.1 mM CdCl slightly inhibited glucose uptake whereas 1 mM CdCl greatly reduced glucose uptake in these vesicles. / Master of Science

It is believed that the presence of certain trace elements in the skin may play an important role in the formation of melanomas. In this work, neutron activation analysis and x-ray fluorescence analysis were used to determine trace element concentrations in cancerous, noncancerous and normal swine skin samples and in non-cancerous and normal swine tissue samples. In-vivo x-ray fluorescence analysis was also used to determine trace element concentrations in cancerous, non-cancerous, and normal swine skin. Data on forty-eight trace elements in each sample were obtained and correlated. The limited number of cancerous samples made definitive conclusions about trace element imbalances uncertain. Nevertheless, the in-vivo XRFA method was shown to be a very useful method for trace element determination. Additionally, good base line data were obtained for trace element concentrations in a variety of organs of Sinclair miniature swine. / Master of Science
