PURPOSE The final goal of regenerative periodontal therapy is to restore the structure and function of the periodontium destroyed or lost due to periodontitis. However, the role of periosteum in periodontal regeneration was relatively neglected while bone repair in the skeleton occurs as a result of a significant contribution from the periosteum. The aim of this study is to understand the histo...

Objective The aim of this study was to investigate the regeneration process of the nasal mucosa after a surgically created mucosal defect in the rabbit nasal septum, and to evaluate the effects of different interventions. Methods A 7 mm-diameter circular mucosal defect was made in the septum of forty New Zealand white rabbits. The rabbits were divided into four groups (ten rabbits in each gro...

Scalp defect management is complicated secondary to reduced laxity in the scalp and forehead area. For reconstruction of larger defects with exposed bone and loss of the periosteal layer, free flap reconstruction is one option for single-stage surgery, although the procedure is lengthy and includes the possibility of flap loss. We successfully performed a single-stage reconstruction of a large ...

This paper is to present a defect detecting and locating method of tubular cylindrical conductor based on alternating current impedance measurement theory. A defect estimation can be made through the impedance measurement of some distance on the inner and the outer surfaces of the tubular cylindrical conductor. A defect in the thickness direction can be located by the skin effect influence on i...

Proteus syndrome is a rare congenital disorder comprised of subcutaneous and internal hamartomas, miscellaneous skin and vascular nevi, skeletal and nervous system and eye malformations, with characteristic manifestations including hemihypertrophy, local gigantism, macrodactyly and cerebriform thickness of soles and palms. A 23 year-old man with diagnosis of proteus syndrome had sever ane...

Sebaceoma is a benign tumor with sebaceous differentiation. It usually presents as a yellowish papule or nodule on the face and scalp. This is a report of a 27-year-old-woman who presented with a giant, 6cm×4.5 cm exophytic tumor on her head. Clinically, we considered several diseases; however, the histological and immunohistochemical features matched those of sebaceoma. The lesion was excised ...

INTRODUCTION Microfracture does not properly repair full-thickness cartilage defects. The purpose of this study was to evaluate the effect of intraarticular injection of the small-molecule compound kartogenin (KGN) on the restoration of a full-thickness cartilage defect treated with microfracture in a rabbit model. METHODS Full-thickness cartilage defects (3.5 mm in diameter and 3 mm in depth...

In this study, the feasibility of using a one dimensional 16-element flexible ultrasonic transducer (FUT) array for nondestructive testing at 150 °C is demonstrated. The FUT arrays were made by a sol-gel sprayed piezoelectric film technology; a PZT composite film was sprayed on a titanium foil of 75 µm thickness. Since the FUT array is flexible, it was attached to a steel pipe with an outer di...

Epitaxial LaFeO 3 exhibits thickness dependent OER electrocatalysis which balances catalysis at surface defect states with charge transport through the film.
