BACKGROUND AND PURPOSE To assess safety and efficacy data of a new bioactive coil (Cerecyte) which is loaded with polyglycolic acid on the inside of the coil. METHODS Fifty-four patients harboring 55 aneurysms were treated with Cerecyte coils. These aneurysms were matched in localization and size with aneurysms treated with bare platinum coils. RESULTS Periprocedural complications and handl...

Cerecyte second-generation coils feature inner surfaces coated with an absorbable polyglycolic acid (PGA) polymer. Their use is expected to accelerate aneurysm organization, but time course data are limited. The present experimental study was therefore conducted to clarify the processes by pathological examination. Methods. Two types of experimental aneurysms were initially generated in adult m...

BACKGROUND The purpose of this retrospective study was to identify an appropriate material that can be used as a covering for patients with a spontaneous pneumothorax (SP). A total of 279 patients were studied over a period of eight years. METHODS The patient characteristics, surgical details and perioperative outcomes were analyzed. We compared the clinicopathological characteristics between...

statement of the problem: recently allogenic mesenchymal stem cells are proposed to have multipotential progenitor cell capabilities to differentiate into cementoblasts, osteoblasts, and periodontal ligament fibroblasts. purpose: the aim of the present study was to compare the efficacy of human umbilical stem cells cultured on polylactic acid (pla), polyglycolic acid (pga) membrane with pla/pga...

We developed a new fabrication technique for 3-dimensional scaffolds for tissue engineering of human heart valve tissue. A human aortic homograft was scanned with an X-ray computer tomograph. The data derived from the X-ray computed tomogram were processed by a computer-aided design program to reconstruct a human heart valve 3-dimensionally. Based on this stereolithographic model, a silicone va...

INTRODUCTION Surgery of the ear and nose often involves drilling, resulting in exposure of the bone surfaces. Fibrin is usually used to cover the exposed bone surfaces; however, this approach may result in granulation, infection, stenosis, and adhesion. Several other methods are available for covering the exposed bone surfaces. For example, implantation of skinand fascia-free grafts (nonpedicle...

Two surgical techniques were used to evert the bladder into the vagina for observation and repair of bladder tears that were associated with parturition. One technique involved an incision through the vaginal floor into the peritoneal cavity just caudal to the cervix, and prolapse of the bladder into the vagina. The second technique involved a 3-cm incision through the urethra, 5 cm cranial to ...
