Efeitos preventivos do exercício físico sobre as proteínas ciclooxigenase-2 (COX-2) e fator de crescimento de vasos derivado do endotélio (VEGF) no músculo cardíaco em ratos tratados com dexametasona

Dexamethasone (DEXA) is a synthetic glucocorticoid widely used in the handling of several drugs, for its proven benefits in fighting inflammation and allergies. Despite their benefits, their chronic use leads to several side effects that include changes in the body in the metabolism of carbohydrates, lipids and proteins. Moreover, being an anti-inflammatory, acts on the arachidonic acid pathway, reducing the expression of the enzyme cyclooxygenase (COX-2) and growth factor derived from the endothelium of blood vessels (VEGF) in various tissues. However, its effects on the myocardium are still uncertain. The physical training (PT), in turn, promotes effects contrary to those caused by chronic use of DEXA, however, little is known about the preventive effects of TF in the side effects of Dexa in the myocardium. Therefore, the aim of this study was to determine if the TF has the ability to prevent and/or mitigate the effects of Dexa in protein expression of COX-2 and VEGF in the myocardium. Forty animals were divided into 4 groups: sedentary control (SC), sedentary treated with Dexa (SD), trained control (TC) and Trained treated with Dexa (TD) and submitted to a protocol of physical training on the treadmill for 70 days (1 h/day-5 days per week, 60% of physical capacity) or kept sedentary. Over the past 10 days, rats were treated with Dexa (Decadron, 0.5 mg/kg per day, ip) or saline. During training the animals were weighed weekly and during treatment daily. At the end of treatment was made to measure fasting glucose levels of animals. The rats were killed with excess anesthesia and cardiac muscle was removed, weighed, homogenized, centrifuged and stored at -20° C for analysis of protein expression of VEGF and COX-2 by Western blotting technique. Treatment with dexamethasone caused a weight loss of 18% in sedentary animals and 13% in trained as well as elevated levels of fasting glucose in sedentary (88%). The TF was unable to mitigate the loss in...

Capacidade de suporte de carga de Latossolo Vermelho cultivado com cana-de-açúcar e efeitos da mecanização no solo

The objective of this work was to determine the load support capacity (LSC) of an Oxisol and, through compressibility models, relate it to wheel-soil interactions under management systems with one and three sugarcane crop cycles, with mechanized harvest. LSC evaluations were carried out on undisturbed soil samples, collected at planting row and bed, in four layers: 0.00-0.10, 0.10-0.20, 0.20-0.30, and 0.300.40 m. The contact area between wheels and soil was determined in order to estimate the contact pressure by agricultural machinery on the soil. Pre-consolidation pressures were used to determine LSC. The system with three cycles showed higher LSC than the system with only one cycle. The load support capacity of the soil evaluated in the range of friability is greater than the contact pressures applied to the soil by the wheels of the studied agricultural machines.

Contração de polimerização e expansão higroscópica de resinas compostas: análise pela técnica de video-imagem

To evaluate the volumetric changes due to polymerization and thermocycling on different resin-composites. Methods: Thirteen A2 Universal Dentin shade resin-composites (n = 10) from eight manufacturers were evaluated (4Seasons, Grandio, Venus, Amelogen Plus, P90, Z350, Esthet-X, Amaris, Vita-l-escence, Natural-Look, Charisma, Z250 and Opallis). The polymerization shrinkage percentage (PS) was calculated using an image measurement device (ACUVOL - Bisco Dental). Equal volumes of material, standardized by a semisphere polyurethane matrix (d = 3mm) were used and, after 5 minutes of relaxation, the baseline volume measurements were obtained with 18 J of energy dose from the LED light-curing unit. Measurements were obtained after 5 minutes and PS values calculated. Specimens were stored in a drydark environment for 24 hours and re-measured. Specimens were then thermocycled in distilled water between 5oC and 55oC for 20,000 cycles, subjected to another volume measurement at 5,000 cycle intervals. Specimens were gently dried prior to each measurement. Results: Repeated measurements were made using ANOVA (α = 0.05) showed that all resin-composite volumes were influenced by the number of cycles. Volumes at 5 minutes post-polymerization (12.47 ± 0.08) were significantly lower than those at baseline (12.80 ± 0.09). Volumes at 24 hours (12.43 ± 0.19) were insignificantly lower than those at 5 minutes postpolymerization. With regards to the impact of thermocycling, all specimens showed statistically significant increases in volume after 5,000 cycles (13.04 ± 0.22). Although statistically different from those after 5,000 cycles, there was no statistically significant difference between volumes measured at 10,000 (12.87±0.21), 15,000 (12.92±0.24), and 20,000 (12.84±0.23) cycles. Conclusion: According to the video-imaging analysis, thermocycling caused a significant expansion in resin-composites tested, the volume increase was not able to...
