1. Anatomical characters and chemical profile of leaves of three species in Lauraceae family
ABSTRACT The Lauraceae family is widely distributed in tropical and subtropical climates, has more than 2500 species and in the taxonomic point of view, it is one of the most difficult families to identify species. The aim of this study was to analyze the leaf anatomy of three species of Lauraceae (Ocotea indecora (Schott) Mez, Nectandra barbellata Coe-Teix.

2. Morphology and fine organization of the spermatheca of Haplotropis brunneriana (Orthoptera: Pamphagidae)
Abstract We investigated the morphology and structure of spermatheca in Haplotropis brunneriana (Orthoptera: Pamphagidae) by light and electronic microscopy. The spermatheca can be subdivided into a tubular seminal receptacle and a multiple-coiled spermathecal tube, both of which are composed of cuticular intima, epithelium layer, basal lamina and muscle lay

3. Influence of consumption of probiotics on presence of enterobacteria in the oral cavity
Clinical benefits of probiotics have been clearly reported in different gastrointestinal disorders, many of them caused by enterobacteria. The oral cavity is a port of entry and can be an important reservoir of these microorganisms. This work evaluated whether consumption of probiotics was able to influence the presence of enterobacteria in the oral cavity a

4. Cavidades secretoras nos órgãos vegetativos aéreos de Copaifera trapezifolia Hayne (Leguminosae, Caesalpinoideae) / Secretory cavities in the aerial vegetative organs of Copaifera trapezifolia Hayne (Leguminosae, Caesalpinioideae).
As copaíbas, pertencentes à família Leguminosae, subfamília Caesalpinioideae, são conhecidas pela produção de uma óleo-resina com propriedades antiinflamatórias, utilizada na medicina popular e pela indústria farmacêutica. A substância é retirada do tronco da árvore, através do uso de um trado que perfura o caule até que a óleo-resina escorr

5. Influence of probiotics on Candida presence and IgA anti-Candida in the oral cavity
Probiotics are defined as microorganisms that promote benefits to host health, mainly by regulating resident microbiota. Disequilibrium in microbiota can favor the growth of opportunist microorganisms and the development of pathologies, like candidosis caused by yeasts of the Candida genus. This work evaluated whether probiotics consumption was able to influ

6. Análise morfológica das espermátides e dos espermatozóides de Chrysomya megacephala (Fabricius) (Diptera: Calliphoridae) nos tratos reprodutores
Diptera constitutes one of the four largest orders of insects. The Oriental latrine-fly Chrysomya megacephala (Fabricius) belongs to the family Calliphoridae and is associated with medic, veterinary, sanitary and forensic issues. The aim of this research was to characterize the utrastructural aspects of the spermiogenesis and spermatozoa of the C. megacephal

7. Anatomia e ultra-estrutura foliar de Pectis brevipedunculata: ontogenia de cavidades secretoras e estrutura Kranz / Leaf anatomy and ultrastructure of Pectis brevipedunculata: secretory cavity development and Kranz structure
Com o uso de técnicas de microscopia de luz e eletrônica de transmissão e varredura, este trabalho caracteriza a anatomia foliar de Pectis brevipedunculata (Asteraceae), enfatizando a estrutura Kranz e a ontogenia das cavidades secretoras. A folha é anfiestomática e possui simetria dorsiventral relativamente bem definida. Apresenta mesofilo radiado circ

8. O genero Dahlstedtia Malme : embriologia, sistema reprodutivo e biossistematica
Flowers, fruits and seed abortion was studied in two Brazilian species: Dahlstedtia pinnata e D. pentaphy/la (Leguminosae, Papilionoideae). Such a study was developed through investigations of: 1. floral development, microsporogenesis, ovule and early seed development following open, self- and cross-pollination, in order to compare the results to other papil

9. Interaction of a salivary mucin-secretory immunoglobulin A complex with mucosal pathogens.
This study examined the interaction of a human salivary low-molecular-weight mucin (MG2) with Staphylococcus aureus and Pseudomonas aeruginosa by using both solution-phase and solid-phase assays. In solution phase, MG2 in human submandibular-sublingual saliva (HSMSL) bound to the bacterial surface; however, the highly purified mucin isoforms (MG2a and MG2b)

10. Regional variation in respiratory epithelium of the nasal cavity of the bandicoot (Isoodon macrourus).
The non-olfactory ciliated epithelium of the nasal cavity was investigated in the bandicoot (Isoodon macrourus), a small ground-dwelling marsupial. Two distinct epithelial types were identified and designated conchal and septal. Conchal epithelium is non-secretory. It covers most of the naso- and maxilloturbinates, the lateral nasal wall, and part of the max

11. Organization of Monoterpene Biosynthesis in Mentha. Immunocytochemical Localizations of Geranyl Diphosphate Synthase, Limonene-6-Hydroxylase, Isopiperitenol Dehydrogenase, and Pulegone Reductase1
We present immunocytochemical localizations of four enzymes involved in p-menthane monoterpene biosynthesis in mint: the large and small subunits of peppermint (Mentha x piperita) geranyl diphosphate synthase, spearmint (Mentha spicata) (−)-(4S)-limonene-6-hydroxylase, peppermint (−)-trans-isopiperitenol dehydrogenase, and peppermint (+)-pulegone reducta

12. Development of Peltate Glandular Trichomes of Peppermint1
Cryofixation and conventional chemical fixation methods were employed to examine the ultrastructure of developing peltate glandular trichomes of peppermint (Mentha × piperita). Our results are discussed in relation to monoterpene production and the mechanism of essential oil secretion. Peltate glands arise as epidermal protuberances (initials) that divide a
