O objetivo deste trabalho foi avaliar o consumo de nutrientes e o desempenho produtivo e econômico de ovinos confinados da raça Santa Inês, alimentados com dietas com diferentes taxas de inclusão de torta de macaúba. Os animais (24) foram distribuídos em delineamento de blocos ao acaso, nos tratamentos com 0, 100, 200 e 300 g kg-1 de torta de macaúba na matéria seca da dieta, em seis repetições, durante 60 dias de confinamento. A adição de torta de macaúba a taxas crescentes à dieta aumentou linearmente o consumo de proteína bruta, extrato etéreo, fibra em detergente neutro e a conversão alimentar. Não houve diferença no consumo de matéria seca, ganho médio diário e ganho de peso vivo total com a adição da torta. O tratamento com inclusão de 100 g kg-1 apresentou a melhor relação custo:benefício na avaliação das receitas bruta e líquida obtidas com a venda dos animais vivos e abatidos. A adição da torta de macaúba em até 300 g kg-1 da dieta não altera o desempenho produtivo dos animais, entretanto, a inclusão de 100 g kg-1 proporciona melhor retorno econômico.

Chemicals binding to membrane receptors may induce events within the cell changing its behavior. Since these events are simultaneous and hard to be understood by students, we developed a computational model to dynamically and visually explore the cAMP signaling system to facilitate its understanding. The animation is shown in parts, from the hormone-receptor binding to the cellular response. There are some questions to be answered after using the model. The software was field-tested and an evaluation questionnaire (concerning usability, animations, models, and the software as an educational tool) was answered by the students, showing the software to be a valuable aid for content comprehension.

S(-) Bupivacaine (S(-)BVC) and Lidocaine (LDC) are widely used local anesthetics (LA). Hydroxypropyl beta-cyclodextrin (HP-beta-CD) is used as a drug-carrier system. The aim of this work was to characterize inclusion complexes between LA and HP-beta-CD. The affinity constants determined at different pHs show favourable complexation. The release kinetics experiments showed that S(-)BVC and LDC changed the released profiles in the presence of HP-beta-CD. Nuclear magnetic resonance experiments gave information about the interaction between LA and the cyclodextrin cavity. This study focused on the physicochemical characterization of drug-delivery formulations that come out as potentially new therapeutic options for pain treatment.

Characteriza of the inclusion complex ropivacaine: beta-cyclodextrin. Ropivacaine (RVC) is a widely used local anesthetic. The complexation of RVC with beta-cyclodextrin (beta-CD) is of great interest for the development of more efficient local anesthetic formulations. The present work focuses on the characterization of the RVC:beta-CD complex by nuclear magnetic resonance (NMR). The stoichiometry of the complex is 1:2 RVC:beta-CD. DOSY-NMR shows that the association constant is 55.5 M-1. Longitudinal relaxation time results show that RVC changes its mobility in the presence of beta-CD. This study is focused on the physicochemical characterization of inclusion complexes that are potentials options for pain treatment.

Hydroxymethylnitrofurazone (NFOH) is a prodrug that is active against Trypanosoma cruzi. It however presents low solubility and high toxicity. Hydroxypropyl-beta-cyclodextrin (HP-beta-CD) can be used as a drug-delivery system for NFOH modifying its physico-chemical properties. The aim of this work is to characterize the inclusion complex between NFOH and HP-beta-CD. The rate of NFOH release decreases after complexation and thermodynamic parameters from the solubility isotherm studies revealed that a stable complex is formed (deltaGº= 1.7 kJ/mol). This study focuses on the physico-chemical characterization of a drug-delivery formulation that comes out as a potentially new therapeutic option for Chagas disease treatment.

Croton zehntneri, a plant native to northeastern Brazil, is widely used in folk medicine to treat gastrointestinal problems and has rich essential oil content. The essential oil of C. Zehntneri was analyzed by GC-MS, and its inclusion complex with β-cyclodextrin (β-CD) was characterized by both vibrational spectroscopy and differential scanning calorimetry (DSC). Estragol was the major component identified in the essential oil by the study. IR spectra indicated an interaction of β-CD with essential oil from C. zehntneri, a finding corroborated by the stability constant and scanning calorimetry. Microencapsulation within β-CD has the potential to mask sensory attributes and increase aqueous solubility of oils, thereby improving their applicability as drugs.

Resonance is a useful concept that shows how electrons are shared between two or more atoms and allows a prediction of the chemical reactivity and relative stability of reagents, intermediates, and products. An educational software that enables interactive exploration of the concepts related to resonance and thereby facilitates its understanding was developed. The software was field-tested, and an evaluation questionnaire concerning the software as an educational tool was answered by the students and professors involved in the test. The results led to the conclusion that the developed computer application can be characterized as an auxiliary tool that assists teachers in their lectures and students in their learning process.

Nos últimos anos, inúmeros problemas surgiram na área da saúde em decorrência, sobretudo, dos avanços ocorridos no campo das biotecnociências. Percebendo-se a exigüidade de espaço, no atual currículo médico, para a discussão de muitas dessas questões, alunos e professores da Fundação Educacional Serra dos Órgãos (FESO) propuseram a criação do Núcleo de Estudos em Filosofia e Saúde (NEFISA), espaço destinado a fomentar o debate, o ensino e a pesquisa sobre os assuntos que tenham sua emergência na interface da Filosofia com a Medicina e a Saúde. O escopo do presente artigo é apresentar o trabalho desenvolvido no NEFISA-FESO.

As Diretrizes Curriculares Nacionais do Curso de Graduação em Medicina enumeram, entre os objetivos do currículo de graduação, aprender a aprender e ter competência e habilidade para avaliar, sistematizar e decidir as condutas mais adequadas com base em evidências científicas, bem como habilidades de escrita e leitura. Sob o viés particular do auxílio ao ensino e à aprendizagem, propomos que a metacognição seja entendida como uma tecnologia educacional simbólica. Para isto, fizemos uso da Fenomenologia de Schultz, em suas reflexões sobre o uso de símbolos, como o arcabouço lógico a unir os campos da tecnologia educacional e a metacognição. Este texto se organiza em quatro tópicos principais: o primeiro introduz o conceito de tecnologia educacional simbólica; o segundo, o conceito de metacognição; o terceiro procura unir os dois primeiros ao discutir o conceito e o papel dos símbolos na perspectiva fenomenológica; o quarto, mais operacional, exemplifica como a metacognição faz uso de símbolos e cifras para gerenciar o processo de aprendizagem, enquadrando-se, assim, no conceito de Tecnologia Educacional Simbólica.

A insuficiência do modelo biomédico para a resolução da maioria dos problemas de saúde da população vem sendo discutida. Diversos autores referem que a realização da consulta médica se associa a melhores resultados quando apoiada nos pressupostos do modelo centrado no paciente, dentre os quais se destaca a inclusão da perspectiva do paciente. Para que isso ocorra, é necessário conhecer as dimensões físicas, psicossociais e culturais que a compõem e incluí-las na realização de entrevistas médicas. Como a formação do médico na graduação ainda é apoiada no modelo biomédico, a mudança de paradigma para a realização de consultas médicas suscita mudanças curriculares significantes
