1. ABRINDO A CAIXA DE PANDORA DOS NANOMEDICAMENTOS: HÁ REALMENTE MUITO MAIS ‘ESPAÇO LÁ EMBAIXO’
Limitations of conventional treatment and dosage forms prompted the investigation of novel approaches that combine efficacy, selectivity and fewer adverse effects. These are the main promises of nanomedicine, generally defined as the application of nanotechnology to the biomedical field. Despite the considerable advances over the years and the large number o

2. Gestão de eventos QBRN e a utilização do modelo Hysplit: uma revisão integrativa de literatura
RESUMO O potencial risco de exposição das populações aos agentes Químicos, Biológicos, Radioativos e Nucleares (QBRN), seja por causas intencionais ou não, configura-se como questão de segurança nacional e demanda um constante aprimoramento do seu gerenciamento. Os modelos de dispersão atmosférica vêm ganhando destaque como ferramenta de apoio à

3. Protein identification from the parotoid macrogland secretion of Duttaphrynus melanostictus
ABSTRACT Background: Bufonid parotoid macrogland secretion contains several low molecular mass molecules, such as alkaloids and steroids. Nevertheless, its protein content is poorly understood. Herein, we applied a sample preparation methodology that allows the analysis of viscous matrices in order to examine its proteins. Methods: Duttaphrynus melanostic

4. Potencialidade dos pavimentos permeáveis na melhoria da qualidade da água do escoamento superficial: uma revisão
Resumo O escoamento superficial pode acarretar em enchentes urbanas e no aumento da carga de poluentes de corpos d’água. O aumento da carga de poluentes é devido ao fato de o escoamento superficial percorrer sobre pavimentos e calçadas e, dessa forma, transportar os poluentes depositados nesses locais. A percolação do escoamento superficial nos pavim

5. Advantages of recovery from pre-slaughter stress in tambaqui Colossoma macropomum (Cuvier 1816) agroindustry in the Amazon
Abstract Tambaqui is the main fish species farmed in the Amazon. It is produced on industrial scale, slaughtered in the field, primarily by post-harvest asphyxia. This procedure, however, is stressful because it depletes energy reserves that should be used in postmortem metabolism, which may compromise fish meat freshness and quality. The present study compa

6. The diversity of citrus endophytic bacteria and their interactions with Xylella fastidiosa and host plants
Abstract The bacterium Xylella fastidiosa is the causal agent of citrus variegated chlorosis (CVC) and has been associated with important losses in commercial orchards of all sweet orange [Citrus sinensis (L.)] cultivars. The development of this disease depends on the environmental conditions, including the endophytic microbial community associated with the

7. The PIN1 family gene PvPIN1 is involved in auxin-dependent root emergence and tillering in switchgrass
Abstract Switchgrass (Panicum virgatum L.; family Poaceae) is a warm-season C4 perennial grass. Tillering plays an important role in determining the morphology of aboveground parts and the final biomass yield of switchgrass. Auxin distribution in plants can affect a variety of important growth and developmental processes, including the regulation of shoot an

8. Characteristics of dr1790 disruptant and its functional analysis in Deinococcus radiodurans
Deinococcus radiodurans (DR) is an extremophile that is well known for its resistance to radiation, oxidants and desiccation. The gene dr1790 of D. radiodurans was predicted to encode a yellow-related protein. The primary objective of the present study was to characterize the biological function of the DR1790 protein, which is a member of the ancient yellow/

9. First records of pollen rain in bromeliad tanks in an area of caatinga in northeastern Brazil
Species of Bromeliaceae have leaves in a spiral configuration. Because of the shape of the rosette thus formed and the imbricate configuration of the leaf sheaths, there is usually a tank in which rainwater and other components of the environment, including pollen grains, accumulate, making such tanks effective pollen rain collectors. The objective of this s

10. Scaffolds of calcium phosphate cement containing chitosan and gelatin
Calcium phosphate cements (CPCs) have potential to be used on repairing damaged bones due to their moldability, bioactivity and bioresorbability. These materials combine calcium orthophosphate powders with a liquid leading to a paste that hardens spontaneously at low temperatures. Hence, CPCs could be applied as scaffolds to support cell/tissue growth. This

11. Desenvolvimento de formulações de Bacillus subtilis para controle da podridão floral em citros / Development of formulations of Bacillus subtilis for the control of citrus post-bloom fruit drop
O Brasil é o maior produtor mundial de laranja, assentado em uma área de 839 mil hectares, dos quais 77% encontram-se localizados na região sudeste do país. Não obstante a importância dessa cultura, o setor citrícola enfrenta sérios problemas representados por doenças fúngicas que diminuem a produtividade, como a podridão floral dos citros (PFC),

12. Influência da restrição calórica no metabolismo bioenergético e estado redox de Saccharomyces cerevisiaee Kluyveromyces lactis / Influence of caloric restriction on energy metabolism and redox state of Saccharomyces cerevisiaee Kluyveromyces lactis
Aging involves a progressive decline in metabolic efficiency of biological systems over time. Although it cannot be avoided, aging phenotypes are delayed in organisms undergoing caloric restriction, a dietary regimen consisting of a reduced availability of calories. The yeast Saccharomyces cerevisiae has proved to be an important model organism for studying
