Background And Objectives: It is widely agreed that primary progressive aphasia (PPA) is a clinical syndrome with at least three distinct variants that differ in phenotype, areas of atrophy, and most common underlying neurodegenerative disease. The distinction between logopenic variant PPA and other variants is important for prognosis and medical management. However, differentiating logopenic from nonfluent agrammatic variant can be difficult. Read More

Purpose: One of the major problems in revision total hip arthroplasty (THA) is severe acetabular bone loss. The aim of our study was to evaluate the clinical outcomes of revision THA using a Kerboull-type reinforcement device (KT plate) and allogeneic structural bone graft.

Methods: This retrospective study evaluated 48 hips that underwent revision THA using a KT plate and allogeneic structural bone graft between 2008 and 2016, with a median follow-up of 6. Read More

Recently, advanced knowledge on secondary neurulation and its application to the clinical experience have led to the deeper insight into the pathoembryogenesis of secondary neurulation with new classifications of the caudal spinal dysraphic entities. Here, we summarize the dynamic changes in the concepts of disordered secondary neurulation over the last two decades. In addition, we suggest our new pathoembryogenetic explanations for a few entities based on the literature and the data from our previous animal research. Read More

Background: Pulmonary atresia (PA) is a heterogeneous congenital heart defect and ventricular septal defect (VSD) is the most vital factor for the conventional classification of PA patients. The simple dichotomy could not fully describe the cardiac morphologies and pathophysiology in such a complex disease. We utilized the Human Phenotype Ontology (HPO) database to explore the phenotypic patterns of PA and the phenotypic influence on prognosis. Read More

As the core component of permanent magnet motor, the magnetic tile defects seriously affect the quality of industrial motor. Automatic recognition of the surface defects of the magnetic tile is a difficult job since the patterns of the defects are complex and diverse. The existing defect recognition methods result in difficulty in practical application due to the complicated system structure and the low accuracy of the image segmentation and the target detection for the diversity of the defect patterns.
