1. Effect of Preparation Additives on the Antimicrobial Activity and Cytotoxicity of Polypyrrole
The search for new biomaterials has increased continuously in recent years and, in this context, the application of polypyrrole (PPy) as a promising material for this function has been reported as a result of positive responses, such as bioactivity and biocompatibility. In this study, PPy was obtained through modifications/adaptations made in methodologies o

2. Response of rhizomes of the invasive Hedychium coronarium J. König (Zingiberaceae) to different soil moisture conditions
ABSTRACT The ability to maintain high competitiveness under a wide range of conditions is common among successful invasive species. The performance of rhizomatous macrophytes in different habitats is closely related to morphological and physiological adaptations in the rhizome system. We investigated the effects of soil moisture conditions on the microstruct

3. Crescimento e partição de massa seca em plantas jovens de amburana (Amburana cearensis (Fr. All.) AC Smith) e de umbuzeiro (Spondias tuberosa Arr. Cam.)
Resumo As espécies amburana (Amburana cearensis (Fr. All.) A. C. Smith) e o umbuzeiro (Spondias tuberosa Arr. Cam.) possuem adaptações fisiológicas e morfológicas às condições climáticas do bioma caatinga e atualmente estão sob ameaça de extinção. Objetivou-se com a realização deste trabalho caracterizar a partição de fotoassimilados das mud

4. A literature review of the pollination strategies and breeding systems in Oncidiinae orchids
ABSTRACT Oncidiinae is an exclusively Neotropical orchid subtribe with about 1600 described species and an impressive array of vegetative and floral morphological adaptations. We present the results of a literature survey on the pollination strategies and breeding systems of this orchid subtribe. The flowers are pollinated by a wide range of insects (mostly

5. Morphological Diversity of Coleoptera (Arthropoda: Insecta) in Agriculture and Forest Systems
ABSTRACT Coleopterans (Coleoptera) are major ecosystem service providers. However ecomorphological features that are comparable in a wide range of invertebrates within this group and in various environments must be found, to be able to study regions with different species, contributing to overcome difficulties of the taxonomic approach and understand the fun

6. The cephalic lateral line system of temperate perches (Perciformes: Percichthyidae) from Argentinean Patagonia
ABSTRACT The species of Percichthys (Percichthyidae) are endemic to southern South America. Some authors have pointed out that the genus includes four valid species, based on the morphology of the head, jaws, and fins. A phylogenetic analysis published by other authors suggests that three of them are morphotypes belonging to the same species, Percichthys tru

7. Tissue culture of ornamental cacti
Cacti species are plants that are well adapted to growing in arid and semiarid regions where the main problem is water availability. Cacti have developed a series of adaptations to cope with water scarcity, such as reduced leaf surface via morphological modifications including spines, cereous cuticles, extended root systems and stem tissue modifications to i

8. Evolution of flatworm central nervous systems: Insights from polyclads
The nervous systems of flatworms have diversified extensively as a consequence of the broad range of adaptations in the group. Here we examined the central nervous system (CNS) of 12 species of polyclad flatworms belonging to 11 different families by morphological and histological studies. These comparisons revealed that the overall organization and architec

9. Neural and morphological adaptations of vastus lateralis and vastus medialis muscles to isokinetic eccentric training
"Adaptações neurais e morfológicas dos músculos vasto lateral e vasto medial para treinamento isocinético excêntrico." Vasto lateral (VL) e vasto medial (VM) são comumente visados em programas de condicionamento/reabilitação devido ao seu papel na estabilização patelar durante a extensão do joelho. Este estudo avaliou as adaptações neurais e mu

10. Bryophytes on rocky outcrops in the caatinga biome: a conservationist perspective
In the state of Paraíba, Brazil, there is an abundance of rocky outcrops, which are typical elements of the semi-arid landscape. Those outcrops provide refuge to species with morphological adaptations to stressful climates and to rare communities of plants, including bryophytes. Nevertheless, there have been no studies of bryophytes in such habitats in the

11. Behavioural biology of Chagas disease vectors
Many arthropod species have adopted vertebrate blood as their main food source. Blood is rich in nutrients and, except for the presence of parasites, sterile. However, this food source is not freely available, nor is obtaining it devoid of risk. It circulates inside vessels hidden underneath the skin of mobile hosts that are able to defend themselves and eve

12. Estudo de proteínas relacionadas ao costâmero em secções longitudinais de músculo sóleo de ratas imobilizadas e reabilitadas pelo alongamento passivo manual intermitente / Study of costameric proteins in soleus muscle longitudinal sections of female rats immobilized and rehabilitated by intermittent passive manual stretching
The interface between sarcolemma and extracellular matrix in skeletal muscle tissue is constituted by specialized proteins that are responsible for the transversal and longitudinal forces transmission to the myofiber. Skeletal muscle adaptations to physiological and pathological forces, such as segmental immobilization and rehabilitation exercises, may contr
