Do estado da droga à droga no Estado

Should taste be discussed? Are there themes in the human life that should not be discussed? Why? What is it aimed when certain themes are discussed or not? The goal of this short paper is to consider the use of so called forbidden drugs in the State. Does the State want to deal with it? Can the State face this problem properly? How has the State tried to deal with such a situation and such a problem? Four researchers of a german university put forward their points of view according to their historical and cultural background. For them this question must be openly and plainly discussed in order to assume that it is also a problem of public health and not only of criminality. In this way a simple prohibition does not solve the problem. The State has the responsibility of elucidating the theme in order to enable the citizen to the use of drugs and to the responsibility for its consequences.

Composição florística de um trecho da mata ciliar do Córrego dos Antunes município de Jaú - SP

A mata ciliar é de extrema importância para a boa qualidade da água assim como evita a erosão do solo das margens dos corpos d´água. No entanto, grande parte das matas ciliares estão em processo de degradação, sendo sua restauração ou recomposição uma emergência. Para isso torna-se necessário saber qual é a composição florística da mata ciliar a ser recuperada. O presente trabalho analisa a composição florística de um trecho da mata ciliar do córrego dos Antunes, situado no município de Jau/SP, a qual está muito degradada. Foram feitas coletas quinzenais entre os meses de abril a setembro de 2008, nas quais foram coletadas amostras (parte reprodutivas ou ramos com folhas) das espécies arbóreas com lenho e DAP igual ou superior a 5 cm. Foram encontradas espécies exóticas, de mata de brejo, xerófitas e espécies que de fato ocorrem em matas ciliares e entre essas ultimas espécies que não foram relatadas em matas ciliares da região.

Exigências ambientais europeias: novos desafios competitivos para o complexo eletrônico brasileiro

The objective of this paper is to evaluate the implications of the european environmental requirements for electronic equipment on brazilian electronic industry sector. These deter-minations deal with elimination of hazardous substances and management of electronic products waste and have reached not only the electronic sector companies in international level, but brazilian electronic sector as well. Most brazilian companies of the electronic sector are getting complied with the requirement that restricts the use of hazardous substances. The main consequences of this process are technological innovations and changes on contractual relationships among companies. Foreign companies branches are more advanced than local ones in terms of timing of compliance to the new requirements and technological perfor-mance, showing an alignment with headquarter strategies. Not being complied with these requirements avoid companies to achieve commercial benefits and open space for questions about policies Brazil must take.

Aperfeiçoamento em equipamento para digestão de amostras por via úmida

Aperfeiçoamento em equipamento para digestão de amostras por via úmida. É descrito um aperfeiçoamento em equipamento para digestão de amostras por via úmida que emprega tubos de digestão (20) fechados não encapsulados e aquecimento condutivo que possibilita a rápida decomposição de amostras botânicas, alimentícias, clínicas, ambientais e similares, promovendo um gradiente de temperatura em direção à parte superior do tubo de digestão, permitindo que a temperatura da fase gasosa seja inferior à da fase líquida, de forma que as digestões são realizadas à pressão pouco elevada e, consequentemente, os tubos de digestão utilizados podem ter paredes menos espessas, permitindo o rápido aquecimento e resfriamento das amostras, bem como baixo custo de operação e manutenção, simplicidade, alta frequência analítica,; redução do consumo de reagentes e diminuição da geração de resíduos, dito equipamento provido de um gabinete (10) que evita a contaminação da atmosfera do laboratório por vapores ácidos e a perda dos componentes voláteis da amostra durante o aquecimento

Diretrizes de conduta e tratamento de síndromes febris periódicas associadas à criopirina (Criopirinopatias–CAPS)

To establish guidelines based on cientific evidences for the management of cryopyrin associated periodic syndromes. The Guideline was prepared from 4 clinical questions that were structured through Pico (Patient, Intervention or indicator, Comparison and Outcome), to search in key primary scientific information databases. After defining the potential studies to support the recommendations, these were graduated considering their strength of evidence and grade of recommendation. 1215 articles were retrieved and evaluated by title and abstract; from these, 42 articles were selected to support the recommendations. 1. The diagnosis of Caps is based on clinical history and clinical manifestations, and later confirmed by genetic study. Caps may manifest itself in three phenotypes: FCAS (mild form), MWS (intermediate form) and Cinca (severe form). Neurological, ophthalmic, otorhinolaryngological and radiological assessments may be highly valuable in distinguishing between syndromes; 2. The genetic diagnosis with NLRP3 gene analysis must be conducted in suspected cases of Caps, i.e., individuals presenting before 20 years of age, recurrent episodes of inflammation expressed by a mild fever and urticaria; 3. Laboratory abnormalities include leukocytosis and elevated serum levels of inflammatory proteins; 4. Targeted therapies directed against interleukin-1 lead to rapid remission of symptoms in most patients. However, there are important limitations on the long-term safety. None of the three anti-IL-1β inhibitors prevents progression of bone lesions.

Erva mate minimiza as alterações do perfil lipídico promovidas por elevado consumo de sacarose

The yerba mate (Ilex paraguariensis) is composed of bioactive that interfere with lipid metabolism. The objective was to evaluate if daily consumption of mate tea (MT) change the lipid deposits and dyslipidemia caused by excessive consumption of sucrose. Thirty male Wistar rats (40 days old) were divided into four groups: Group C - free access to commercial chow and deionized water; S - free access to commercial food, water and sucrose solution 30% (w/v) in water; MTS and deionized - free access to commercial feed solution, water, 30% sucrose (w/v) and treated with daily infusion of MT (soluble mate Leão Júnior®) via orogastric tube at a dose of 100 mg/kg/mc for 8 weeks. After the trial period the lipid profile was evaluated by the following parameters: a) direct weighing of the retroperitoneal (RP) and epididymal (EPI) adipose tissues; b) determination of plasma total cholesterol, triglycerides and HDL cholesterol concentration. The MT promoted the reduction of 1.4 times in both tissues RP and EPI in MTS group compared to group S. Treatment with MT decreased 2.7 times triglyceride in the MTS group compared with the group S. The sucrose consumption did not alter the plasma cholesterol concentration, however the consumption of MT significantly reduced total cholesterol circulating. The HDL cholesterol concentration, in the MTS group, showed higher concentration than in group S (1.3 times). MT prevents in young male rats the increase of lipid deposits and dyslipidemia caused by excessive consumption of sucrose.

Efeito do ácido tranexâmico associado à cola de fibrina sobre o reparo ósseo: estudo histológico em ratos

The bone repair process is controlled by complex molecular mechanisms that involve systemic and local factors. Fibrin glue is derived from human plasma and mimics the final pathway of coagulation network. Tranexamic acid inhibits fibrinolysis and prevents or decreases the formation of degradation products of fibrin and fibrinogen. The purpose of this study was to evaluate histologically in rats the effect of tranexamic acid associated with the fibrin glue on bone healing. The experiment used 60 (n = 5) male rats in: GI: Control, GII: fibrin glue, GIII tranexamic acid and GIV /fibrin glue/tranexamic acid. Bone defect (2.5mm diameter) was created in right tibia. The animals were euthanized at 7,14 and 30 days postoperatively, and the pieces were processed with hematoxylin and eosin. The results showed at 7 days post-operative surgical cavity filled with dense connective tissue rich in fibroblasts, permeated by delicate neoformed bone trabeculae in percentage of 70-80% for GI, GII and GIII and GIV to 94.8%. At 14 days post-operative newly formed bone was found between 75-85% for GI, GII and GIII and percentage above 95% for GIV. At 30 days postoperative GI and GIV showed 95-100% of mature bone tissue; GII and GIII in percentage close to 80-90%. Based on the results and methodology is concluded that fibrin / tranexamic acid glue association has positive action on bone repair.
