    Abstract: The objective of this study was to evaluate the viability of the Ginkgo biloba mini-cutting technique, as well as the influence of substrates and different concentrations of indole butyric acid (IBA) on adventitious rooting in addition to the protein and sugar content in the mini-cutting. Mini-cuttings were 4 ± 1 cm in length, with the bases immersed in solutions of 0, 1000, 2000, and 3000 mg L-1 IBA. They were then planted in polypropylene tubes using two substrates (vermiculite and Tropstrato®) and maintained under greenhouse conditions for 60 d. The experiment was carried out with a 2 × 4 factorial scheme (substrates × IBA). There was no influence of IBA application on the promotion of rhizogenesis in Ginkgo biloba mini-cuttings. The rooting percentages were higher than 55% regardless of the treatment used. The vermiculite substrate showed a higher number of roots (4.94) and lower mortality (11.60) of mini-cuttings than Tropstrato®. We conclude that the mini-cutting technique is feasible for Ginkgo biloba, and the use of IBA is not necessary. We found that the induction ofadventitious rooting depended on the biochemical composition of the mother plants, due to the translocation of non-reducing sugars and leaf proteins for root formation.

    Abstract: Infant formulas are an alternative to replace or supplement human milk when breastfeeding is not possible. The knowledge of human milk’s bioactive compounds and their beneficial effects has attracted the interest of researchers in the field of infant nutrition, as well as researchers of technology and food sciences that seek to improve the nutritional characteristics of infant formulas. Several scientific studies evaluate the optimization of infant formula composition. The bioactive compound inclusion has been used to upgrade the quality and nutrition of infant formulas. In this context, the purpose of this systematic literature review is to assess the scientific evidence of bioactive compounds present in infant formulas (α-lactalbumin, lactoferrin, taurine, milk fat globule membrane, folates, polyamines, long-chain polyunsaturated fatty acids, prebiotics, and probiotics) and their effects on infant nutrition and health. Through previously determined criteria, studies published in the last fifteen years from five different databases were included to identify the advances in the optimization of infant formula composition. Over the last few years, there has been optimization of the infant formula composition, not only to increase the similarities in their content of macro and micronutrients but also to include novel bioactive ingredients with potential health benefits for infants. Although the infant food industry has advanced in the last years, there is no consensus on whether novel bioactive ingredients added to infant formulas have the same functional effects as the compounds found in human milk. Thus, further studies about the impact of bioactive compounds in infant nutrition are fundamental to infant health.

    Abstract: O gênero Tibouchina apresenta aproximadamente 350 espécies, dentre elas, Tibouchina affinis fothergillae, Tibouchina heteromalla, Tibouchina moricandiana var. vinaceae e Tibouchina sellowiana. Por se tratarem de espécies nativas do Brasil, podem ser utilizadas para revegetação de áreas antropizadas, devido à característica pioneira. A presente pesquisa objetivou estudar a propagação vegetativa via miniestaquia, utilizando ácido indol butírico (AIB) e ácido fúlvico (AF), bem como realizar determinações bioquímicas e quantificar a produtividade de minicepas destas espécies. Os propágulos foram coletados de um minijardim clonal, nos meses de abril, junho, setembro e novembro/2017, confeccionados com 5+1 cm de comprimento, corte em bisel na base e reto no ápice, mantendo-se um par de folhas reduzidas à metade. As bases das miniestacas foram submetidas aos tratamentos: 0 mg L-1AIB/AF, 2000 mg L-1AIB, 2000 mg L-1AF e 2000 mg L-1AIB+AF. O experimento foi instalado utilizando-se tubetes de 53 cm³ com vermiculita, avaliados após 33 dias de permanência em casa de vegetação, considerando-se a porcentagem de enraizamento das miniestacas. O delineamento foi inteiramente casualizado, num esquema fatorial de 4x4 (quatro épocas de coleta x quatro tratamentos), conduzido individualmente/espécie. As espécies não responderam aos tratamentos com AIB/AF. Nas diferentes épocas de coleta dos propágulos, o enraizamento foi superior a 95% para todas as espécies em abril, setembro e novembro, exceto para Tibouchina sellowiana com 49% de enraizamento no mês de novembro, demonstrando o efeito direto das condições ambientais as quais as plantas matrizes estavam sujeitas, sob a rizogênese. Conclui-se que não há necessidade da aplicação de AIB/AF para a propagação vegetativa das diferentes espécies de Tibouchina, sendo viável o uso da técnica de miniestaquia. Visando a maior produtividade de miniestacas, recomenda-se coletar os propágulos em abril para Tibouchina affinis fothergillae e Tibouchina moricandiana var. vinaceae, em novembro para Tibouchina heteromalla e em junho para Tibouchina sellowiana.

    Abstract: As vacinas contra a hepatite B são produzidas pela expressão do gene viral codificado para o antígeno de superfície do vírus da hepatite B (HBsAg) em levedura, há mais de 20 anos. De acordo com os dados da OMS, a vacina de hepatite B tem até três anos de estabilidade quando armazenada entre 2 ºC e 8 ºC. O objetivo deste estudo foi de avaliar se, no momento da liberação, os critérios de qualidade da vacina de hepatite B foram mantidos após sete anos da data de validade. Foram analisados frascos de vacinas multi-dose (10 e 5 doses), sendo três lotes de cada produtor (A, B e C). Todos os lotes foram avaliados quanto às características de aparência visual, potência, endotoxina bacteriana, presença de timerosal, conteúdo de hidróxido de alumínio e pH por meio de testes validados. Os nove lotes avaliados sete anos após a data de expiração tiveram resultados similares quando comparados às concentrações na época de liberação dos lotes, realizada pelo Instituto Nacional de Controle de Qualidade em Saúde (INCQS). Os estudos confirmaram a manutenção da qualidade da vacina após o período de expiração. Estes dados podem subsidiar uma futura avaliação para extensão do prazo de validade das vacinas.

    Abstract: The use of Brazilian native species for ornamental purposes is a promising alternative for local floriculture. Seeking to contribute with new information in this context, the present study aimed to evaluate the rooting performance of mini-cuttings from three Tibouchina species (T. aff. fothergillae, T. heteromalla and T. moricandiana var. vinacea) as affected by the use of indolebutyric acid (IBA) and fulvic acid (FA). Mini-cuttings with 5 cm in length were prepared with plant material from clonal mini-hedges and submitted to different treatments as follows: control treatment (T1); 2,000 mg L-1 IBA (T2); 2,000 mg L-1 FA (T3) and 2,000 mg L-1 IBA + 2,000 mg L-1 FA (T4). Planting was carried out in plastic containers filled with vermiculite, and, after 26 days under greenhouse conditions, the following variables were evaluated: mini-cuttings rooting percentage (RP), roots number (RN), roots length (RL), initial leaves maintenance (ILM) and sprouting (SP). The experiment was conducted under a completely randomized design in a 3 x 4 factorial scheme, with four replications and 20 minicuttings per plot. Rooting percentages were higher than 90% in all three species, regardless of IBA or FA treatments. RP, ILM and SP did not show statistically significant interaction between the treatments. For RN, T2 and T4 promoted the best results on T. aff. fothergillae (12.62 and 14.92, respectively) and T2 resulted in maximum values for T. heteromalla (15.65). For RL, T2 and T4 were statistically superior on T. heteromalla (9.52 and 8.20 cm, respectively). The use of IBA and FA is dispensable for rhizogenesis induction on mini-cuttings from the studied species

    Abstract: Ilex paraguariensis , commonly known as yerba mate, is a tree species native to South America. Its commercial value is due to the manufacturing of teas, with potential also in the pharmacological and cosmetic industries. Vegetative propagation of yerba mate is considered an innovation to the traditional production systems based on sexual propagation. The present study aimed to evaluate the rhizogenic potential and chemical attributes of mini-cuttings from 15 yerba mate genotypes, as well as to verify the correlation between phytochemical and rooting-related variables. Mini-cuttings were collected from a pre-existing mini-clonal hedge and the experimental design was completely randomized, with 15 treatments (genotypes), four replications and 10 mini-cuttings per plot. After 120 days, mini-cuttings were assessed regarding rooting, mortality, callogenesis and leaf retention percentages, percentage of mini-cuttings with both calluses and roots, number of roots and average root length. At the time of collection, subsamples from each plot were used for phytochemical analyses including total phenolic compounds, protein, caffeine and theobromine contents and antioxidant activity. Rooting percentages ranged from 5 to 72.5%, with significant variation among genotypes. Adventitious rooting and phytochemical profile of yerba mate mini-cuttings are genotype-dependent. Leaf retention is a relevant factor in the rooting of yerba mate mini-cuttings and the levels of total phenolic compounds, antioxidants and theobromine present in mini-cuttings are negatively correlated components to Ilex paraguariensis adventitious rooting.

    Abstract: The zalcitabine (ddC) has been extensively used in the treatment of HIV patients due to its antiretroviral activity. The quality control of this active principle in medications is of outstanding importance to public health. The principal objective of the current study was the development of an alternative analytical methodology for the zalcitabine determination using a voltammetric process. The zalcitabine gives a reduction peak (at - 1.22  V versus Ag/AgCl) at the hanging mercury drop electrode (HMDE). The differential pulse voltammetric response is evaluated with respect to the scan rate (20 mV/s), pulse amplitude (50 mV), support electrolyte (Clark-Lubs buffer), pH (2.0), and other variables. The response is linear over the 10.0 to 28.0 mg/L (47 to 133  μ M) concentration range, and the detection limit is 2.08 mg/L. The validation of this method was realized using a governmental Brazilian document (Inmetro, 2007) and the results are reported for medication drugs.

    Abstract: Os produtos sob regime de vigilância sanitária classificados como "produtos para saúde" compreendem os "materiais médicos". Atos regulatórios de 1999 a 2005 foram selecionados e classificados por assunto, possibilitando discutir o perfil dessas publicações. A classificação foi conduzida avaliando cada legislação, sua ementa e texto publicado em Diário Oficial da União. Para subsidiar a discussão, propomos uma classificação em oito assuntos (temas). A partir dela, foi possível correlacionar e demonstrar a prevalência de assuntos publicados e, assim, indicar uma tendência de temas contemplados em cada ano do período avaliado. Como reflexão, entendemos que o Sistema Nacional de Vigilância Sanitária, neste caso, possui uma oportunidade de atuação única devido a seu arcabouço normativo organizado, capaz de atender a campos de atuação como registro, boas práticas, tramitações relacionadas às empresas de âmbito sanitário e pós-comercialização. No entanto, as legislações apresentadas somente terão aplicabilidade e eficiência se existir o conhecimento atualizado por parte dos profissionais de saúde das normas gerais de vigilância sanitária que apoiem processos decisórios de gestão mais eficientes, sem prejuízo da segurança da população.
