Protocolo de biossegurança e gerenciamento de resíduos no ensino de radiologia odontológica da Faculdade de Odontologia de Araçatuba-UNESP

In dentistry, the technic and radiographic processing incur the possibility of cross infection and environmental contamination. The dentist is responsible for the patient and dental team. For this reason he needs to take a protocol to prevent the spread of microorganisms and environmental exposure to risk factors. The protocols are introduced in the dentistry school as an important teaching tool, whose learning and application reinforce the importance of continuity of these actions in the professional activity. The objective of this paper is to present the biosafety and waste management protocol used in the dental radiology clinic of Araçatuba Dental School, including procedures for the prevention of biological and environmental contamination.

Produção de composto orgânico a partir de residuos de plantas medicinais

Extraction of active principles from medicinal plants generates wastes usually discharged. This process does not extract minerals from plant tissues, which may be considered of great value in organic composting. Wastes of 81 medicinal plant species processed at Centroflora/Anidro industry were analyzed for macro and micronutrients, and according to the results, three different ways to elaborate the compost were proposed: a) wastes of medicinal plants with high content of a specific mineral, aiming to fertilize soils where would be cultivated species that need high quantities of that mineral; b) wastes with mineral contents in order to support specific failures on mineral content of a soil; c) wastes of the eleven richest species in each nutrient that should elevate all mineral contents in soil.

Efectos de la administración de betabloqueante en la remodelación ventricular inducida por el tabaquismo en ratas

Background: The role of the adrenergic system on ventricular remodeling induced by cigarette smoking is unknown. Objective: To investigate the influence of propranolol on ventricular remodeling induced by exposure to tobacco smoke. Methods: Rats were divided into three groups: 1) C, n=10 - control group; 2) F, n=10 - animals exposed to tobacco smoke; 3) BB, n=10 - animals receiving propranolol and exposed to tobacco smoke (40 mg/kg/day). After 2 months, the animals underwent echocardiographic and morphometric analyses. One-way ANOVA (mean ± standard deviation) or the Kruskal-Wallis test (median and interquartile interval) was used. Results: Group BB showed a lower heart rate than group F (C = 358 ± 74 bpm, F = 374 ± 53 bpm, BB = 297± 30; P = 0.02). Group F showed greater end-diastolic diameters (C = 18.6 ± 3.4 mm/kg, F = 22.8 ± 1.8 mm/kg, BB = 21.7 ± 1.8 mm/kg; P = 0.003) and left ventricular (LV) end-systolic diameters (C = 8.6 ± 2.1 mm/kg, F = 11.3 ± 1.3 mm/kg, BB = 9.9 ± 1.2 mm/kg; P = 0.004), adjusted for body weight (BW) and a tendency towards a lower ejection fraction (C = 0.90 ± 0.03, F = 0.87 ± 0.03, BB =0.90 ± 0.02; P = 0.07) than group C. Group BB showed a tendency towards a lower LV/BW ratio than group F (C = 1.94 (1.87 - 1.97), F = 2.03 (1.9-2.1) mg/g, BB = 1.89 (1.86-1.94); P = 0.09). Conclusion: Administration of propranolol attenuated some of the variables of ventricular remodeling induced by the exposure to tobacco smoke in rats.

Influencia de la separación de residuos sólidos urbanos para reciclaje en el proceso de incineración con generación de energía

This work analyses the recuperation of the energy of Municipal Solid Waste (MSW) through the incineration process. It considers the up to date tendency of segregation (separation) of plastic, paper and cardboard, glass and metals and their influence in the fluxes of mass and energy in the incineration system of MSW. For its development was used information related to the generation of MSW in Bauru city and the Combust software. The results so obtained allowed the estimation of the Caloric power of the typical MSW and also of this residue when one considers the separations of paper/cardboard and plastic for recycling.
