ABSTRACT
Objetivou-se com o presente estudo monitorar o comportamento do uso territorial de um macho de onça parda, capturado no Parque Estadual da Serra do Brigadeiro (PESB), por meio da telemetria, usando colar de GPS via Satélite Globalstar. O monitoramento de doze meses resultou na transmissão via satélite de 328 localizações, as quais sugerem que a área utilizada por esse felino seja de aproximadamente 610km2, sendo esta a maior área já descrita para a espécie. Foi possível observar que apenas 20% das localizações ocorreram dentro da área do PESB. O comportamento territorial observado neste trabalho mostra a vulnerabilidade do animal a ações antrópicas, como a caça, atropelamentos e o contato com patógenos entre animais silvestres e domésticos. Observou-se também que duas rodovias configuram barreiras artificiais para o deslocamento do animal, possivelmente impedindo o fluxo gênico entre o PESB e dois outros importantes parques. Com os dados levantados é possível a sugestão de ações de manejo, como a criação de uma conectividade efetiva entre o PESB, o Parque Estadual do Rio Doce e o Parque Nacional do Caparaó, o que poderia contribuir para o intercâmbio genético entre as populações e, dessa forma, favorecer a conservação não somente da onça parda.
We aimed to study the territorial behavior of a male cougar, captured in the Parque Estadual da Serra do Brigadeiro (PESB), using a GPS collar and the Globalstar Satellite. Monitoring the animal for nine months we obtained 328 locations. The data suggest that the area used by this feline is approximately 610km2, the largest area described for this specie. It was also possible to observe that only 20% of the locations of the animal occurred within the PESB area. The territorial behavior observed in this study shows the vulnerability of the animal to human activities such as hunting, road kill and contact with pathogens from domestic animals. It was also observed that two roads constitute artificial barriers for animal movement, possibly preventing gene flow between the PESB and two other parks. The creation of an effective connectivity between the PESB, the Parque Estadual do Rio Doce and the Parque Nacional do Caparaó is critical to ensure genetic exchange between the animal populations and thereby promote their conservation.

PURPOSE: To study the relation between the average level and variability of blood pressure (VBP) obtained by ambulatory monitoring (AMBP) and the geometric pattern (GP) of the left ventricle (LV) obtained by echocardiography (ECHO) in patients with hypertension (Hy) METHODS: AMBP and ECHO were performed in 37 patients with Hy, divided into three groups: group A--11 women using antihypertensive therapy (AH); group B--15 men using AH and group C--7 male and 4 female without AH. The GP of LV was obtained by ECHO based on mass index (MI) and relative thickness of the wall (RTW). Mean systolic (MSBP) and diastolic (MDBP) were analyzed during daytime (DT) and nighttime (NT) periods. VBP was defined by mean standard deviation (SD) of mean pressures considered. RESULTS: In G-A, there was a significant association between the MI and both VBP and MSBP (r = 0.65 and p < 0.005, r = 0.61, and p < 0.005, respectively), and MSBP and VBP during the DP (r = 0.64 and p < 0.005, r = 0.75, and p < 0.005). In G-B, there was a relation between the LVRTW (r = 0.55 and p < 0.005), and MSBP during the DP (r = 0.65 and p < 0.005). In G-C, there was a significant association (p < 0.005) between the MI and the MDBP in the DP and with the MSBP in the NP (r valueS ranged from 0.51 to 0.66). There was also a significant relation (p < 0.005) between the LVRTW and the SD of all variables in both DP and NP (r ranged from 0.47 to 0.78 and mean diastolic in the wakeful period (r = 0.42 to 0.78) and MDBP in the DP (r = 0.42 and p < 0.05). CONCLUSION: Both the increase in VBP and the mean BP are involved in the changes of LVGP in Hy.

Respostas teciduais locais a um implante acrilico substituindo a parede anterior do seio frontal foram estudadas experimentalmente no seio frontal do cao. Quando colocado sem agressao ao restante do seio, o acrilico permaneceu por 6 meses no local, embora o ducto nasofrontal tenha se mantidido permeavel. Apos curetagem do seio, entretanto, ocorreu extrusao da protese.Quando, apos a curetagem, a cavidade foi obliterada com a resina acrilica, o implante permaneceou no local sem levar a alteracao macroscopica ou histologica importante

A prospective study of 48 infants with periventricular-intraventricular hemorrhage was carried out to evaluate the role of daily lumbar punctures, instituted from the time of diagnosis of the hemorrhage, in prevention of posthemorrhagic hydrocephalus and improvement in immediate outcome. The data lead to the following conclusions: (1) minor hemorrhage (Grade I) is associated with minimal risk of death or hydrocephalus; (2) moderate hemorrhage (Grade II) is associated with low risk of death and intermediate risk of hydrocephalus, and serial lumbar punctures do not reduce these risks; and (3) severe hemorrhage (Grade III) is associated with high risks of death or hydrocephalus or both, and serial lumbar punctures also do not reduce these risks.
