A violência escolar (bullying), é hoje considerada um problema de saúde pública crescente em todo o mundo. Intervir sobre este fenómeno é essencial para melhorar a qualidade de vida das crianças/adolescentes escolarizados, devendo por isso, constituir uma prioridade de pesquisa a incluir na agenda dos enfermeiros. Este estudo teve como objectivo avaliar os resultados de um programa anti-violência escolar, implementado em 307 estudantes do 2º ciclo de uma escola de Lisboa. A avaliação pré e pós Programa, foi feita por questionário, elaborado e validado para este estudo. Constatámos que antes da intervenção, existia um elevado nível de bullying (50% vítimas e 35% agressores), verificando-se também agressões dirigidas a professores (7%) e outros funcionários (9%). O Programa aplicado consistiu na sensibilização/formação de docentes e pais e no treino de competências sociais dos estudantes. Após a intervenção verificaram-se resultados significativos na redução global da violência escolar.

Objective This study assessed pharmacological treatment adherence using the Morisky-Green Test and identified related variables. Method A longitudinal and retrospective study examined 283 patients with hypertension (62.5% women, 73.4 [10.9] years old) who were being monitored by a chronic disease management program for 17 months between 2011 and 2012. Nurses performed all the actions of the program, which consisted of advice via telephone and periodic home visits based on the risk stratification of the patients. Results A significant increase in treatment adherence (25.1% vs. 85.5%) and a decrease in blood pressure were observed (p<0.05). Patients with hypertension and chronic renal failure as well as those treated using angiotensin-converting enzyme inhibitors were the most adherent (p<0.05). Patients with hypertension who received angiotensin receptor blockers were less adherent (p<0.05). Conclusions Strategies such as nurse-performed chronic disease management can increase adherence to anti-hypertensive treatment and therefore contribute to the control of blood pressure, minimizing the morbidity profiles of patients with hypertension.

Avaliou-se a eficácia anti-helmíntica da associação de albendazole 2,0%, cloridrato de levamisole 2,55% e ivermectina 0,08% comparativamente à moxidectina 1% em ovinos naturalmente infectados. Foram selecionados 24 ovinos para a composição de três grupos experimentais com oito animais cada: T1, ovinos tratados com a associação albendazole, levamisole e ivermectina, na dosagem de 1 mL 4 kg-1 de peso corporal; T2, ovinos tratados com moxidectina, na dosagem de 1 mL 50 kg-1 de peso corporal e T3, ovinos sem tratamento anti-helmíntico. Foram realizadas contagens de ovos por grama de fezes (OPG) no primeiro, terceiro, quinto e sétimo dia após os tratamentos. No sétimo dia todos os ovinos foram necropsiados e todos os helmintos encontrados no trato gastrintestinal foram quantificados e identificados quanto ao gênero e à espécie. A associação dos diferentes princípios ativos foi 100% eficaz no combate às espécies Cooperia punctata, C. pectinata, C. spatulata, Trichostrongylus axei, Oesophagostomum columbianum, Trichuris ovis, C. curticei e Strongyloides papillosus e, a moxidectina eliminou as seis primeiras espécies citadas. Contra Haemonchus contortus a associação apresentou eficácia superior (93%) à moxidectina (51,4%). Ambas formulações foram eficazes contra Trichostrongylus colubriformis. A associação medicamentosa utilizada constitui alternativa no controle das nematodioses ovinas.

O objetivo deste trabalho foi avaliar a ação imunoesterilizadora de uma vacina anti-hormônio liberador de hormônio luteinizante (LHRH), composta por ovalbumina-LHRH-7 e tiorredoxina-LHRH-7, em touros mestiços Nelore. Vinte e seis touros, com dois anos de idade, foram distribuídos aleatoriamente em dois grupos de 13 animais. No grupo I, os animais receberam uma dose e dois reforços da vacina nos dias 0, 141, e 287 do experimento. No grupo II, os animais não receberam nenhum tratamento (controle). Para avaliar o efeito da vacina nos touros, foi realizada a mensuração da circunferência escrotal no início do experimento e no dia do abate, 741 dias depois. Por ocasião do abate, também foi coletada uma amostra dos testículos para avaliação histológica. O grupo imunizado apresentou circunferência escrotal ao abate de 22±5,98 cm, menor do que a do grupo controle que foi de 35,6±2,4 cm. Na análise histológica dos animais do grupo imunizado, foi observada degeneração testicular com ausência de espermatozoides em 85% dos animais avaliados, os outros 15% apresentaram redução no número de espermatozoides, em comparação aos animais do grupo controle. A vacina anti-LHRH, com fusão de proteínas, é efetiva na castração imunológica de touros e deve ser considerada como alternativa para utilização na produção bovina extensiva no Brasil.

One old dream of the chemist in the field of the drug research is to create molecules capable of reaching their target with the precision of a missile. To accomplish it these molecules must have the propriety of distinguishing qualitative differences between healthy and diseased cells. A therapy based on this principle, able of eradicating specifically defective cells, or cells affected by a pathogen has an enormous advantage with the regard to the classical approach in which the cytotoxic drugs merely exploit quantitative biochemical and kinetic differences between abnormal and normal cells. We present in this article a review on the chemical synthesis of analogues of desoxyribonucleotides and on results obtained on the specific and irreversible inhibition of undesired genetic expression using the antisense principle.

In this article are described new bioactive N-acylhydrazone (NAH) derivatives, structurally designed as optimization of aryl hydrazones precursors planned by molecular hybridization of two 5-lipoxigenase inhibitors, e.g. CBS-1108 and BW-755c. The analgesic, antiedematogenic and anti-platelet aggregating profile of several isosteric compounds was investigated by using classic pharmacological assays in vivo and ex-vivo, allowing to identify new potent peripheric analgesic lead, a new anti-inflammatory and an antithrombotic agent. During this study was discovered dozen of active NAH compounds clarifying the structure-activity relationship for this series of NAH derivatives, indicating the pharmacophore character of the N-acylhydrazone functionality.

The replicative cycle of HIV presents several events. The proteins involved in these events can be anticipated as pharmacological targets, aiming to the development of anti viral agents. Presently, there are fifteen commercially available anti-HIV drugs, which act at substrate binding site of reverse transcriptase (zidovudine, didanosine, zalcitabine, stavudine, lamivudine and abacavir), at a non-substrate binding site of reverse transcriptase (nevirapine, delavirdine and efavirenz), or by inhibiting HIV protease activity (saquinavir, ritonavir, indinavir, nelfinavir, amprenavir and lopinavir). The present review focus both on these established classes of drugs and on new classes of compounds acting on other virus specific steps.

Currently available anti-HIV drugs can be classified into three categories: nucleoside analogue reverse transcriptase inhibitors (NRTIs), non-nucleoside reverse transcriptase inhibitors (NNRTIs) and protease inhibitors (PIs). In addition to the reverse transcriptase (RT) and protease reaction, various other events in the HIV replicative cycle can be considered as potential targets for chemotherapeutic intervention: (1) viral adsorption, through binding to the viral envelope glycoprotein gp120; (2) viral entry, through blockage of the viral coreceptors CXCR4 and CCR5; (3) virus-cell fusion, through binding to the viral envelope glycoprotein gp 41; (4) viral assembly and disassembly through NCp7 zinc finger-targeted agents; (5) proviral DNA integration, through integrase inhibitors and (6) viral mRNA transcription, through inhibitors of the transcription (transactivation) process. Also, various new NRTIs, NNRTIs and PIs have been developed, possessing different improved characteristics.

The concept of research and the controversy among classical models for C, T & I, outdated by the development of knowledge and Post-modern society needs were revisited through the (3) Quadrants advanced by Donald Stokes in the mid-nineties. The scientific community to fit into these Quadrants was faced with many difficulties and reacted by issuing pseudo-facts, accepted by under-prepared technocrats as viable justifications for conducting research in face of these new paradigms. In a poor country full of contrast and needs such as Brazil, this attitude satisfies the bureaucracy and academic elite, but frustrates government and society, that do not get, in the expected measure, the benefits of their commitment with the Teaching, Research and Extension Sectors mainly embedded in the Public University system. An extension, in fact a contradictory approach, to Pasteur's Quadrant, is proposed to characterize this situation: The Syndrome of Ruetsap's Quadrant.
