15. Pericarp ontogeny of Tapirira guianensis Aubl. (Anacardiaceae) reveals a secretory endocarp in young stage
ABSTRACT Most species of Anacardiaceae have drupes containing secretory structures.. The substances produced by these structures may have importance to industry and folk medicine, and may even cause allergenic effects. This work describes the ontogeny of pericarp of Tapirira guianensis with an emphasis on the secretory structures present at different stages

16. Comparative study of three Marantodes pumilum varieties by microscopy, spectroscopy and chromatography
Abstract Marantodes pumilum (Blume) Kuntze (synonym: Labisia pumila (Blume) Fern.-Vill), Primulaceae, is well known for its traditional use as a post-partum medication among women in Malaysia. Three varieties of M. pumilum, var. alata Scheff., var. pumila and var. lanceolata (Scheff.) Mez. are commonly used. Nowadays, M. pumilum powder or extracts are commer

17. Novelties in secretory structures and anatomy of Rhynchosia(Fabaceae)
Estudo anatômico comparativo foi realizado nas estruturas secretoras de folíolos de táxons pertencentes ao gênero Rhynchosia - taxa de difícil delimitação por possuir relações interespecíficas incertas - a fim de avaliar o valor diagnóstico potencial dessas características anatômicas para atribuição taxonômica. Outro objetivo foi estabelecer

18. Anatomia, análise do óleo essencial e germinação de sementes de três espécies de Viguiera Kunth (Asteraceae - Heliantheae) / Anatomy, analysis of the essential oil and seed germination of three species of Virguiera Kunth (Asteraceae - Heliantheae)
A família Asteraceae é uma das maiores famílias de angiospermas, com ampla distribuição e hábitos muito variados. O gênero Viguiera pertence à subtribo Heliantheae e conta com aproximadamente 180 espécies. No Brasil ocorrem 35 espécies e 27 dessas são endêmicas. Por se tratar de um gênero com muitos representantes, as relações filogenéticas n

19. Trichinella spiralis shares epitopes with human autoantigens
Like other helminths, Trichinella spiralis has evolved strategies to allow it to survive in the host organism, including the expression of epitopes similar to those present in either expressed or hidden host antigens. To identify T. spiralis-derived antigens that are evolutionarily conserved in the parasite and its host and that could be responsible for its

21. Chemical composition and histochemistry of Sphagneticola trilobata essential oil
Anatomical and histochemical investigations of Sphagneticola trilobata (L.) Pruski, Asteraceae, secretory structures in leaves and stems and the seasonal variation of essential oils were carried out. Histochemical techniques enabled the specific location of the essential oil accumulation in the internal (canals) and external structures (trichomes). Histochem

22. Fusão Homotípica e Heterotípica entre Vacúolos Parasitóforos de Leishmania spp / Homotypic and Heterotypic Fusion between Leishmania spp. Parasitophorous Vacuoles
Most non-viral intracellular pathogens gain entrance into human and animal host cells by classic or modifIed phagocytosis and are thus lodged in phagosomes which they may or not continue to occupy in the course of infection. Their survival and multiplication within host cells depend on modulation of the compositional and functional phenotypes of the phagosom

23. Secretory structures of Ipomoea asarifolia: anatomy and histochemistry
Ipomoea asarifolia (Desr.) Roem. & Schult., Convolvulaceae, is a weed that infests agricultural areas and is toxic to cattle. In spite of its toxicity, the leaves of this plant are used in traditional remedies in the state of Bahia, Brazil. The present work describes the leaf anatomy of I. asarifolia and characterizes the exudates of its secretory structures

24. Estudos químicos e anatômicos em espécies de Myrtaceae e Asteraceae e primeiros registros de coléteres em Myrtaceae / Chemical and anatomical studies in Myrtaceae and Asteraceae species and first report of colleters in Myrtaceae
This paper presents data on the chemical composition and antibacterial activity of volatile oils fron three Myrtaceae genera (Callistemon, Kunzea and Melaleuca) grown in Brazil, and one species of the Asteraceae family (Sphagneticola trilobata), ruderal and used in folk medicine. The volatile oils of Myrtaceae species were investigated for its chemical compo
