AIM The purpose of this study was to compare the efficacy in vitro of gutta-percha removal from obturated root canals using ProFiles. METHODOLOGY Forty-eight human root canals with curvatures ranging between 25 and 45 degrees were instrumented by a standardized method to an apical ISO size 30 and 0.04 taper. They were obturated with vertically condensed gutta-percha. Retreatment was performed...

Abstract Caryocar brasiliense Camb. (Malpighiales: Caryocaraceae) is widely distributed in the Brazilian savanna and its fruits are used by humans for food, production of cosmetics, lubricants, pharmaceutical industry. This plant damaged galling insects. Number these insects their parasitoids was recorded, field (galls) laboratory (adults emerged from galls), three C. crown heights, during year...

objective: knowledge about the internal anatomy of the root canal and apical foramen is a critical prerequisite for root canal therapy and is necessary for the success of endodontic treatment. this study aimed to determine the distance of apical foramen from the anatomical apex and apical constriction, evaluate the deviation of apical foramen from the anatomical apex and specify the most common...

Dentoalveolar fracture is defined as a fracture in the bone surrounding the teeth without any extension to the basal bones of the maxilla or mandible (1). As for other parts of the facial skeleton, the treatment strategy for dentoalveolar fractures consists of fracture reduction, fixation and immobilization (2); however, some dentoalveolar fractures are difficult to treat. In some dentoalveola...

Dune plants are subjected to disturbance and environmental stresses, but little is known about the possible combined effects of such factors on growth and spatial colonization. We investigated how clones of Sporobolusvirginicus, a widespread dune species, responded to the independent and interactive effects of breakage of rhizomes, breakage position and burial regime. Horizontal rhizomes were s...

The distribution of radiocesium was examined in bamboo shoots, Phyllostachys pubescens, collected from 10 sites located some 41 to 1140 km from the Fukushima Daiichi nuclear power plant, Japan, in the Spring of 2012, 1 year after the Fukushima nuclear accident. Maximum activity concentrations for radiocesium ¹³⁴Cs and ¹³⁷Cs in the edible bamboo shoot parts, 41 km away from the Fukushima Daiichi...

The ocular surface, which is among the most accessible and vulnerable tissues in mammals, is protected by a complex tear film composed of lipid, aqueous and mucin layers. In spite of its importance, the molecular nature of the mucin contribution remains uncertain. Since membrane mucins have been implicated in the protection of other epithelia, we have analysed rat corneal and conjunctival tissu...

A protein that was immunologically related to the erythrocyte and brain alpha-240-subunit and to the brain beta-235-subunit of spectrin was characterized by immunoblotting and was detected by immunofluorescence in the apical part of ciliated cells from quail oviduct. After immunogold-labeling electron immunocytochemistry, spectrin was detected mainly in a fibrillar meshwork located between the ...

Asymmetric mRNA localization targets proteins to their cytoplasmic site of function. We have elucidated the mechanism of apical localization of wingless and pair-rule transcripts in the Drosophila blastoderm embryo by directly visualizing intermediates along the entire path of transcript movement. After release from their site of transcription, mRNAs diffuse within the nucleus and are exported ...
