The results were compared using Student’s t-test and level of significance was set at p < 0.05. Results: In the great toe, the mean maximum force increased from 72.2 N preoperatively to 106.8 N 1 year after surgery. The mean contact area increased from 7.6 cm(2) preoperatively to 8.9 cm(2) 1 year

after surgery and the mean force-time integral increased from 20.8 N*sec to 30.5 N*sec. All changes were statistically significant (p < 0.05). For the first metatarsal head region, the mean maximum force increased from 122.5 N preoperatively to 144.7 N one year after surgery and the mean force-time integral increased from 42.3 N*sec preoperatively Selleckchem LDK378 to 52.6 N*sec 1 year postoperatively (p = 0.068 and p = 0.055, respectively). The mean AOFAS score increased from 61 points preoperatively to 94 points at final followup (p < 0.001). The average hallux valgus angle decreased from 31 degrees to 9 degrees and the average first intermetatarsal angle decreased from 14 degrees to 6 degrees (p < 0.001 for both). Conclusion: Our results suggest that postoperative physical therapy and gait training with a Chevron osteotomy may help to improve weightbearing

of the great toe and first ray. Therefore, we believe there is a restoration of more physiological gait patterns in patients who receive this postoperative regimen.”
“Key to understand predator choice is the relationship between predator and prey abundance. There are few studies related to prey selection and availability. Such an approach is still current, because the ability to predict aspects of the diet in response to changes in prey availability is one CH5183284 of the major problems Dinaciclib cell line of trophic ecology. The general objective of this study was to evaluate prey selection by two species (Characidium cf. vidali and Pimelodella lateristriga) of the Mato Grosso stream. in Saquarema. Rio de Janeiro, Brazil. Benthos and fishes were collected in June, July and September of 2006 and January and February

of 2007. Fish were collected with electric fishing techniques and benthos with a surber net. Densities of benthic organisms were expressed as the number of individuals per/m(2). After sampling, the invertebrates were fixed in 90% ethanol, and, in the laboratory, were identified to the lowest taxonomical level. Approximately, seventy individuals from each species were selected randomly in each month. Fishes were fixed in 10% formalin in the field and transferred to 70 GL ethanol in the laboratory. Fishes had their stomachs removed for subsequent analysis. Fish diet was described according to the numeric frequency method. The Manly Electivity Index was applied in order to verify prey selection. The most abundant families in both benthos and diet of both fish species were the same, indicating that these species consume mainly most abundant prey in the environment. We concluded that prey selection occurs even for preys that had small abundance in the environment.
