13. Water interaction and bond strength to dentin of dye-labelled adhesive as a function of the addition of rhodamine B
ABSTRACT Objective This study investigated the effect of the fluorescent dye rhodamine B (RB) for interfacial micromorphology analysis of dental composite restorations on water sorption/solubility (WS/WSL) and microtensile bond strength to dentin (µTBS) of a 3-step total etch and a 2-step self-etch adhesive system. Material and Methods The adhesives Adp

14. Tumoral chromoblastomycosis: a rare manifestation with typical complementary exams
Abstract: Chromoblastomycosis is a chronic subcutaneous fungal infection caused by traumatic implantation of dematiaceous fungi in the skin. The clinical presentation is usually a verrucous plaque lesion and the diagnosis is confirmed by the visualization of muriform bodies at direct examination or at the histologic study. This report describes a rare case o

15. Effects of aluminum on the elongation and external morphology of root tips in two maize genotypes
ABSTRACT The objective of this study was to evaluate the effects of toxic levels of aluminum (Al) on the growth and external morphology of root tips in two maize genotypes with differential Al tolerance. The maize genotypes UFVM-100 (Al-sensitive) and UFVM-200 (Al-tolerant) were treated with 0 and 50 mM Al in a 0.5 mM CaCl2 solution at pH 4.5; root elongatio

16. The cuticular profile of the aristiform hair as a characteristic feature of Abrawayaomys (Rodentia: Cricetidae)
ABSTRACT The cuticle is the outermost of the three cellular layers of the mammalian hair. It comprises numerous keratinized scales, whose morphology, combined with other microscopic characteristics of the hair, confers characteristic signature traits to various different species. This study aimed to analyze whether the cuticular patterns of the aristiform ha

17. Micromorphology of the upper anthecium in Mesosetum Steud. and related genera (Poaceae, Arthropogoninae) and its taxonomic applications
Abstract Mesosetum is a Neotropical genus with 25 species, and 21 of them occur in Brazil. Mesosetum forms a clade closely related with Keratochlaena rigidifolia and Tatianyx arnacites. The objective of this work was to establish the taxonomic value of the upper anthecium micromorphology for the group. A total of 96 specimens, representing all Mesosetum spec

18. Seed coat diversity in some tribes of Cucurbitaceae: implications for taxonomy and species identification
To evaluate their diagnostic value in systematic studies, seed coat morphology for 16 taxa from 11 genera of Cucurbitaceae were examined using stereomicroscopy and scanning electron microscopy. The taxa included representatives of the tribes Benincaseae, Bryonieae, Coniandreae, and Luffeae in order to evaluate their diagnostic value in systematic studies. Ma

19. Micro-sized erosions in a nanofilled composite after repeated acidic beverage exposures: consequences of clusters dislodgments
Objective: To evaluate the hardness (KHN), color stability (DE), and superficial micromorphology of two categories of composites after immersion in either distilled water or grape juice for up to 45 days. MATERIAL AND METHODS: Cylindrical specimens (6 mm diameter x 2 mm thick) were obtained according to the factors: composite [Opallis (FGM) and Filtek Z35

20. Micro-shear bond strength and surface micromorphology of a feldspathic ceramic treated with different cleaning methods after hydrofluoric acid etching
Objective: The aim of this study was to evaluate the effect of feldspathic ceramic surface cleaning on micro-shear bond strength and ceramic surface morphology. Material and Methods: Forty discs of feldspathic ceramic were prepared and etched with 10% hydrofluoric acid for 2 minutes. The discs were randomly distributed into five groups (n=8): C: no tre

21. Light intensity on growth, leaf micromorphology and essential oil production of Ocimum gratissimum
Light conditions can promote the growth and development of plants and contribute to increase the essential oil production of commercially cultivated medicinal and aromatic species. In view of the great importance of Ocimum gratissimum L., Lamiaceae, as an aromatic plant, the objective of this work was to determine the effect of light intensities (approximate

22. Evaluation of roughness and micromorphology of epoxy paint on cobalt-chromium alloy before and after thermal cycling
It has been suggested that the epoxy paint used to coat metal substrates in industrial electrostatic painting applications could also be used to mask metal clasps in removable dental prostheses (RDP). The purpose of this study was to evaluate both the influence of thermal cycling and the in vitro roughness of a surface after application of epoxy paint, as we

23. Dinâmica da formação de crostas superficiais em função de práticas de preparo do solo e chuva simulada / Dynamic of surface crust formation in different tillage systems and simulated rainfall
As crostas são o resultado da degradação da estrutura superficial dos solos, favorecem a erosão e a degradação ambiental dos solos. Este estudo avaloiu a dinâmica da formação de crostas superficiais e as consequencias sobre a porosidade, condutividade hidráulica (K), retenção de água, densidade (Ds) e a rugosidade de um Argissolo Vermelho amarel
