13. Morphological variations of the three otoliths of some species of the family Loricariidae (Ostariophysi: Siluriformes)
ABSTRACT Otoliths are three pairs of calcareous structures found in the inner ear of bony fish. In many cases they display a species-specific morphology. The present study describes morphological variations of otoliths, namely lapillus, asteriscus and sagitta, of eleven species belonging to four loricariid subfamilies. Otolith structures that characterize th

14. Larvicidal efficacies of plants from Midwestern Brazil: melianodiol from Guarea kunthiana as a potential biopesticide against Aedes aegypti
A total of 36 ethanol extracts from different anatomical parts of 27 plant species (18 families), native to the Pantanal and Cerrado biomes in Midwest Brazil, was assessed for their effect against Aedes aegypti larvae, the vector of dengue, hemorrhagic dengue, Zika and chikungunya fevers. Only the extract obtained from seeds of Guarea kunthiana (Meliaceae) p

15. Defensive behavior associated with secretions from the prosternal paired glands of the larvae of Heliconius erato phyllis Fabricius (Lepidoptera, Nymphalidae)
Defensive behavior associated with secretions from the prosternal paired glands of the larvae of Heliconius erato phyllis Fabricius (Lepidoptera, Nymphalidae). Our work presents for the first time, the defensive behavior associated with the release of the product of the prosternal paired glands of the larva of Heliconius erato phyllis Fabricius, 1775 (Lepido

16. Availability and use of woody plants in a agrarian reform settlement in the cerrado of the state of Goiás, Brazil
Protected areas are important sources providing plant resources for human populations, and contributing to the livelihood and income of families. To test the ecological apparency hypothesis, that there is positive relationship between the visibility of a species and its use, we conducted an ethnobotanical survey in the protected area of the Itaúna rural set

17. A família no processo de saúde-doença no envelhecer com HIV/Aids
Family has passed through distinct chances both in structures and functional throughout its conception some millions of years ago. Some of these chances have happen in respect to the reduction on children number in families; increase of families with no children; increase of elder people among others. All such chances, one way or another, influence social ev

18. Reconocimiento de diásporas de Malveae (Malvaceae) en muestras de suelos de zonas serranas (Sierras Chicas, Córdoba, Argentina) afectadas por incendios
As part of a study of post-fire regeneration of native vegetation in montane areas near Falda del Carmen (Sierras Chicas, Córdoba, Argentina), we analyzed the aerial seed bank to help identify the species present in soil samples. Among families with greater diversity and abundance in the study area, the Malvaceae are represented by 14 species belonging to t

19. Influência reversa no consumo entre gerações : um estudo exploratório sobre a influência dos filhos no processo de decisão de compra das famílias
Many different factors contribute for the growth of children¿s role as influential agents in the family decision-making process such as technology in its most different shapes, and how easy is for the children to manage them, besides the recent changes in demographic and household structures with a decrease of number of children per family, people having ch

20. Influence of edaphic variables on the floristic composition and structure of the tree-shrub vegetation in typical and rocky outcrop cerrado areas in Serra Negra, Goiás State, Brazil
The present study analyzed the influence of edaphic variables on the floristic compositions and structures of the arboreal and shrub vegetation of typical cerrado (TC) and rocky outcrop cerrado (RC) communities in the Serra Negra mountain range in Piranhas Municipality, Goiás State, Brazil. Ten 20×50m plots were established in each community, and all indiv

21. Estudo qualitativo e quantitativo de biomarcadores ácidos e hidrocarbonetos presentes em óleos da Bacia Potiguar / Qualitative and quantitative study of acidic and hydrocarbon biomarkers of oil from the Potiguar Basin
rabalho foram sintetizados quatro biomarcadores ácidos, a saber: ácido 5b (H) colânico (2), 5a (H) homopregnânico (4), 8,13-tetraidrocopálico (6) e 15-isocopálico (7). Para tanto, foram utilizadas matérias primas comerciais (ácido litocólico e estigmasterol) e o ácido copálico (extraído e purificado a partir de bálsamo de copaíba). Também foi

22. HydroPaCe: uma metodologia para análise de inibição cruzada em serino proteases através de centroides de regiões hidrofóbicas
Interfaces of protein-protein interactions contain important information about molecular recognition. This work aims at the discovery of conserved patterns in this region. We believe it is essential to understand how substrates and inhibitors are bound and for predicting molecular binding. When an inhibitor binds to enzymes with different structures, sequenc

23. Avifauna de matas ciliares do Rio Batalha e adjacências, região centro-oeste do estado de São Paulo, Brasil
Forest fragmentation and habitat loss in tropical regions are implicated for different organisms responses, with special attention to avian species susceptible to disturbance. They react negatively in the face of changes in their habitats, reducing population size. In this scenario, the riparian forests play an important role as refuge for many species of bi

24. Aerobic and facultative microorganisms isolated from corroded metallic structures in a hydroeletric power unit in the Amazon Region of Brazil
Aerobic and facultative bacteria belonging to the Enterobacteriaceae, Pseudomonadaceae, Bacillaceae, Corynebacteriaceae and Streptococcaceae families have been isolated from corroded metallic structures of a hydroelectric power unit in the Amazon region of Brazil. In addition to anamorphic dematiaceous and moniliaceous fungi, members of the archeobacteria
