The present study was designed to carry out an in vivo and in vitro comparative evaluation of three bio-scaffold augmentation devices used for superficial digital flexor tenorrhaphy in donkeys. Twenty-four clinically healthy donkeys were assigned for three treatment trials (n = 8) using one of three bioscaffold materials (glycerolized bovine pericardium xenograft, tendon allograft and allograft...

Recently, the application of bio-signals in fields health management, human–computer interaction (HCI), and user authentication has increased. This is because development artificial intelligence technology, which can analyze numerous fields. In case analysis bio-signals, results tend to vary depending on analyst, owing a large amount noise. However, when neural network used, feature extraction ...

the aim of this study was to compare the lateral window and osteotome techniques for sinus lifting using histological and histomorphometric methods.in this clinical trial 10 patients (a total number of 14 sinus areas) who needed implant treatment in the atrophic posterior maxilla were enrolled. in all the cases the residual bone height between the sinus floor and the alveolar crest was less tha...

introduction in spite of multiple applications of bioactive glasses, these materials have not been evaluated yet for ridge augmentation. due to the large number of patients who need ridge augmentation and the benefits of nova bone, in comparison with other alloplasts, this study was fulfilled for evaluation of nova bone ability in ridge augmentation. methods the samples of this experimental stu...

Soil pollution is a major human and environmental issue. Among the several components of soil degradation, organic contaminant in regarded as significant factor that causes considerable damage to environment along with health dangers humans. Polychlorinated biphenyls, polycyclic aromatic hydrocarbons, polychlorinated dibenzofurans, poly-brominated fuels particularly gasoline diesel, herbicides,...

Flying insects may enhance their flight force production by contralateral wing interaction during dorsal stroke reversal ('clap-and-fling'). In this study, we explored the forces and moments due to clap-and-fling at various wing tip trajectories, employing a dynamically scaled electromechanical flapping device. The 17 tested bio-inspired kinematic patterns were identical in stroke amplitude, st...
