1. Portable model for vasectomy reversal training
ABSTRACT Objectives To validate an experimental non-animal model for training of vasectomy reversal. Materials and Methods The model consisted of two artificial vas deferens, made with silicon tubes, covered by a white resin, measuring 10 cm (length) and internal and external diameters of 0.5 and 1.5 mm, respectively. The holder of the ducts is made by a

2. Comparative leaf anatomy of some species of Abies and Picea (Pinaceae)
ABSTRACTA number of conifer species are still lacking anatomical data, which is significant because morphological and anatomical data are essential for systematic study. Leaf anatomy was studied in selected species of Abiesand Piceausing light and scanning electron microscopy. Both genera were found to have typical coniferous and highly xerophytic leaves wit

3. Seasonality and chemical elicitation of defense oleoresin production in field-grown slash pine under subtropical climate
Oleoresin is a key defense strategy of advanced gymnosperms, based on the combination of a complex anatomical structure of resin ducts and elaborate terpene biochemistry. Given the vast array of oleoresin economic applications in the chemical, pharmaceutical, agrochemical, and biofuel industries, translating factors that regulate terpene biosynthesis into hi

4. Comparative morpho-anatomical studies of the lesions caused by citrus leprosis virus on sweet orange
The leprosis disease shows a viral etiology and the citrus leprosis virus is considered its etiologic agent. The disease may show two types of cytopatologic symptom caused by two virus: nuclear (CiLV-N) and cytoplasmic (CiLV-C) types. The aim of this study was to compare the morpho-anatomical differences in the lesions caused by leprosis virus-cytoplasmic an

5. Estudo do comportamento mecânico de dutos de aço com reparos compósitos hibridos / Mechanical behavior of steel pipes repaired with a hybrid laminate
Worldwide, steel pipes play an important role in many industrial sectors. Meanwhile, any kind of duct is prone to suffer superficial damages due to corrosion. In this sense, techniques which allow fast and reliable repairs of ducts have a fundamental importance to increase the life cycle, avoid accidents, minimize environmental contaminations and to keep the

6. Caracterização da estrutura anatômica do lenho, dos anéis de crescimento e dos canais de resina de árvores de Pinus caribaea var. hondurensis Barr. et Golf. / Characterization of the anatomical structure of the wood, the growth rings and the resin ducts in Pinus caribaea var. hondurensis Barr. et Golf.
The research on resin tapping trees with pine species have shown the effect of factors that affect the production and quality of resin, related with the species, genetic variability, growth rate, age, forest management, etc.. The gum-resin extraction practices, the concentration, frequency of application of chemical stimulants, the time of year that panels a

7. Degradação da interface de união utilizando diferentes sistemas adesivos em dentes deciduos e permanentes tratados endodonticamente : estudo in vitro / Bonding degradation in endodontic treated permanent and primary teeth using different adhesive systems : an in vitro study
During the endodontic treatment irrigant substances with the purpose of assisting the disinfection of the ducts are used, being the most used the sodium hypochlorite. These substances modify the teeth substrata, which is used in the formation of the hybrid layer and bonding of the adhesive systems to the dentine. The studies are controversial of the shear bo

8. Análise histopatológica e perfil protéico de lesões causadas pelo Citrus leprosis virus tipo nuclear e citoplasmático em Citrus sinensis (l.) Osbeck / Histopathological analysis and proteic profile of lesions caused by Citrus leprosis virus nuclear and cytoplasmatic type in Citrus sinensis (L.) Osbeck
The citrus leprosis of citrus has been considered a disease of great economic importance to citrus producers due to the damage that it causes. The disease is responsible for lesions found in the twigs, leaves and fruits, and it may cause great losses to the untreated orchards. The citrus leprosis has viral etiology being the virus called Citrus leprosis viru

9. Anatomia foliar de espécies de Flacourtiaceae (Sleumer 1980) / Foliar anatomy from species of Flacourtiaceae (Sleumer 1980)
There is no agreement regarding the taxonomic organization of the Flacourtiaceae and the theme is not emphasized in the literature, since there is a lack of taxonomic studies on this family. Several authors point out the close relationship between the families Flacourtiaceae and Salicaceae. Numerous families of plants have members with medicinal uses, standi

11. Methyl Jasmonate Induces Traumatic Resin Ducts, Terpenoid Resin Biosynthesis, and Terpenoid Accumulation in Developing Xylem of Norway Spruce Stems1
Norway spruce (Picea abies L. Karst) produces an oleoresin characterized by a diverse array of terpenoids, monoterpenoids, sesquiterpenoids, and diterpene resin acids that can protect conifers against potential herbivores and pathogens. Oleoresin accumulates constitutively in resin ducts in the cortex and phloem (bark) of Norway spruce stems. De novo formati

12. Detection of Intracellular Bacteria in the Buds of Scotch Pine (Pinus sylvestris L.) by In Situ Hybridization
Bacterial isolates were obtained from pine (Pinus sylvestris L.) tissue cultures and identified as Methylobacterium extorquens and Pseudomonas synxantha. The existence of bacteria in pine buds was investigated by 16S rRNA in situ hybridization. Bacteria inhabited the buds of every tree examined, primarily colonizing the cells of scale primordia and resin duc
