Physiological traits associated with drought tolerance are useful as surrogate traits for drought tolerance. Information on the association of root traits and water use efficiency (WUE) and plant growth in sugarcane is rather limited. The objective of this study was to evaluate genotypic variation for root traits, WUE and growth characters of above ground parts of sugarcane. A 2 × 10 factorial ...

This study analyzes the clot stabilization on root surfaces of teeth impregnated with cotinine and nicotine and the influence of the scaling in the adhesion of blood components, observing the influence of new exposition to nicotine and/or cotinine after scaling. Fifteen human teeth extracted due to periodontal disease of non-smokers patients were selected and manually scaled. Four dentin blocks...

Introduction: The purpose of this study was to evaluate surface topography of WaveOne Gold (WOG) and WaveOne (WO) files using SEM before and after use. Methods: Twelve primary files from each system were scanned for surface defects before instrumentation at 100x and 750x. Each file was planned ti be used to instrument six root canals and then examined under SEM after preparing one, three and six...

Root caries is a lesion located on the root surface of a tooth, usually close to or below the gingival margin. Root caries has become an important dental problem because people are living longer and keeping their teeth longer. As patients grow older, their gums recede and root surfaces are exposed, making them more susceptible to root caries. Any caries-prone patient having gingival recession c...

INTRODUCTION Induced dental root resorption is a common side effect of orthodontic treatment. It is an unpredictable phenomenon, and its etiology is unknown. Odontoclasts responsible for the resorption of the dental tissues--ie, cementum and dentin--share many cytochemical and morphological characteristics with osteoclasts, which are responsible for bone resorption. The aim of this study was to...

Plants depend upon beneficial interactions between roots and microbes for nutrient availability, growth promotion, and disease suppression. High-throughput sequencing approaches have provided recent insights into root microbiomes, but our current understanding is still limited relative to animal microbiomes. Here we present a detailed characterization of the root-associated microbiomes of the c...
