Produzida a partir da sacarose cristalizada, proveniente da cana de açúcar ou de outras fontes vegetais, e ácidos graxos saturados e insaturados, obtidos de glicerídeos presentes em óleos vegetais como algodão, oliva, soja, amendoim, babaçu, palma, dendê, linhaça e milho, podendo ainda ser obtido a partir de gordura animal de bovinos, suínos e caprinos, onde após processo de transesterificação com uma mistura catalisadora cáustica é formado um produto de ação biológica pesticida, agindo sobre pragas agrícolas tais como ácaros, insetos, entre outros, possuindo diversas vantagens e benefícios como por exemplo, o fato de não deixar resíduos tóxicos no meio ambiente e rios alimentos após sua aplicação, a alta biodegradabilidade e a produção a partir de fontes renováveis.

Common bean grown in no-tillage (NT) systems has increased markedly in Brazil. Thus, to optimize the fertilizer recommendations, it is important to know the nutritional requirements of this crop when grown under new and established NT systems, which can change the nutrient availability and crop response to nitrogen (N) fertilization. The objective was to evaluate the extraction and exportation of nutrients by common bean as function of N fertilization on soil under new and established NT systems. The experiment was carried out in two agricultural years, on a Red Nitosol (Alfisol) in Botucatu, São Paulo State, Brazil. A randomized complete block design was used in a split-plot scheme with four replications. The plots consisted of areas under NT systems after different periods of adoption and the subplots of four forms of N application to common bean (T0: control, without nitrogen; T1: 60 kg ha-1 before sowing; T2: 60 kg ha-1 sidedressed at V4 stage; and T3: 60 kg ha-1 before sowing + 60 kg ha-1 sidedressed). The following properties were evaluated: shoot dry matter, nutrient concentration and accumulation in the shoot, grain yield, and nutrient concentration and exportation in the grains. The NT age did not affect common bean yield, nutrition and response to N management. Nitrogen application, especially before sowing, led to higher dry matter and nutrient accumulation by common bean. The nutrient concentration in grains was little influenced by N fertilization. Grain yield and nutrient exportation were highest after double N application (before sowing and sidedressed) or only sidedressed at V4.

In order to make a histological evaluation of the dental alveolus wound healing in presence of the Isradipine (Lomir/Sandoz Pharma), the new calcium channels blockers, forthy-eight albino rats were utilized. These animals were divided in two groups. The animals of group I were considered as control; in group II, after the dental extractions the rats received intraperitonial injections of 2,5 mg/Kg of isradipine, administered a single dose. From each group of animals were sacrificed at 3, 7, 14 and 21 post-operative days. The pieces were fixed, descalcified and embedded in paraffin. The blocks thus obtained were cut at 6 micrometers thick and sections were stained with hematoxylin and eosin for morphological study. According to the results obtained i t was verified that the treated animals did not alter of wound healing after dental extractions
