Taxonomia molecular e filogeografia de Hypostomus strigaticeps (Teleostei: loricariidae) na bacia do alto rio Paraná

Buscando identificar marcadores populacionais que indiquem supostos mecanismos de isolamento entre as populações, no presente trabalho foram realizadas análises filogenéticas e filogeográficas em populações de Hypostomus strigaticeps, com base em sequências de DNA mitocondrial do gene ATPase 8/6. Um total de 32 exemplares provenientes de 11 populações de quatro sub-bacias: rio Mogi-Guaçu (duas), rio Paranapanema (cinco), rio Tietê (três) e Rio do Peixe (um), tiveram DNA extraído e o gene ATPase 8/6 completamente amplificado (840 pares de base) e sequenciado. As sequências obtidas foram alinhadas com o programa Bioedit, as análises filogenéticas foram realizadas no programa MEGA 5.0 através do método de Neighbor-Joining, Máxima Parcimônia e Minimun-Evolution, com 1000 réplicas de boostrap. Para as análises filogeográficas as sequências foram analisadas no programa TCS. As análises filogenéticas mostraram que a espécie forma uma unidade monofilética composta por duas linhagens: “TG” com representantes das populações dos rios Tietê, Mogi-Guaçu e Rio do Peixe, e “PC” com representantes dos rios Paranapanema e reservatório de Chavantes. A divergência genética da linhagem “TG” é de 0,1% e da linhagem “PP” é de 0,2%, enquanto a divergência genética entre as duas linhagens é de cerca de 1%. Na análise filogeográfica observou-se a existência de seis haplótipos (A-H), sendo o haplótipo A considerado ancestral para as populações analisadas. Apenas os representantes da bacia do Tietê possuem o haplótipo ancestral. Os haplótipos A, B e F possuem a maior frequência (18,51%). Os resultados obtidos para uma população do Mogi-guaçu (Cachoeira de Emas), mostram que estes peixes são muito distantes das demais populações de H. strigaticeps, tanto no ponto de vista filogenético quanto no ponto de vista fitogeográfico...

Variação da temperatura superficial dos músculos masseter e temporal anterior durante o apertamento dental voluntário com placas interoclusais maxilares de duas diferentes espessuras

Muscle activity has been studied indirectly through analyses of temperature variation in skin surface temperature on the masticatory muscles. These procedure may be an important tool for clinical evaluation and assessment of the evolution of temporomandibular disorders, as well as monitoring the adopted protocol. Thus, its utilization for identified pathological alterations on blood circulation and/or on metabolic activity in subcutaneous tissues, such as the masticatory muscles, is justified. The aim of this study was to investigate the effect of occlusal splints’ thickness on the variation of surface temperature of the anterior temporal and masseter muscles during rest and clenching. It were analyzed 20 symptomatic subjects (10 males and 10 females) selected through the Research Diagnostic Criteria (RDC) questionnaire. Temperature expressed in degrees Celsius (ºC) was measured on the surface of both muscles measured with the aid of a digital thermometer with an infrared radiation reading system. The surface temperature of the anterior temporal and masseter muscles presented significant reduction during teeth clenching in relation to the mandibular rest position. However, there were no significant differences between conditions with and without occlusal splint or between the different thicknesses of splints analyzed. Masticatory muscles showed a considerable similar behavior for both sides, and no significant distinctions were observed between male and female patients.

Análise temporal da cobertura do solo na zona de amortecimento de reserva biológica

The Municipal Biological Reserve of Serra do Japi shelters an important forest remnant of Atlantic Rainforest in the state of São Paulo. For its ecological importance, were created instruments for environmental and territorial management of the Conservation Unit, with the regulation of the use and occupation of the land in its Buffer Zone (BZ) in 2004. The objective of this study was to analyze the evolution of the land cover in the BZ region of the Municipal Biological Reserve of Serra do Japi in Jundiaí-SP, between 1989 and 2010. It was used in this study the image analysis of the satellite LANDSAT-TM5, with the help of software ILWIS and IDRISI. The results showed that urban occupation has increased 37.47% and the agro pastoral and reforestation areas have decreased 36.62% and 72.22% respectively, while forest areas have increased 49.57%. However, the relative importance of the forest area in BZ ranged from 46.60% in 1989 to 69.71% in 2010, leading to the conclusion that this region was favored by changes in land cover in the period evaluated, despite strong pressure for urban expansion in its surroundings.

Produção do monóxido de titânio em estrelas variáveis

Mira are pulsating variable stars in advanced stages of evolution. Their atmospheres are sources of intense absorption bands attributed to molecular titanium monoxide (TiO). It has been suggested that the abundance of TiO reaches its maximum value near the minimum light. In this sense, the study of the processes of formation and destruction of TiO in circumstellar envelopes of Mira stars, not only allows us to understand the physical and chemical processes that occur in these environments, as it allows to verify the correlation between the abundance of TiO and its light curve. However, the main mechanisms of formation and destruction of TiO are poorly known and, consequently, the possible correlation between the abundance of this species and the light curve. In these sense, we studied the main processes of formation and destruction of titanium monoxide in molecular layers of Mira atmospheres and determined its temporal variation as function of the stellar radius. The TiO profile along the radius was expected for the different stellar phase, however its abundance is not enough to explain the light curve. The reasons behind it are discussed in details
