Fabrication of Flexible and Transparent Conductive Nanosheets by the UV-Irradiation of Gold Nanoparticle Monolayers.

Conductive films that are highly transparent and flexible are extremely attractive for emerging optoelectronic applications. Currently, indium-doped tin oxide films are the most widely used transparent conductive films and much research effort is devoted to developing alternative transparent conductive materials to overcome their drawbacks. In this work, a novel and facile approach for fabricating transparent conductive Au nanosheets from Au nanoparticles (AuNPs) is proposed.

Conditioned Medium From Mesenchymal Stem Cells Enhances Early Bone Regeneration After Maxillary Sinus Floor Elevation in Rabbits.

Purpose: Conditioned medium from stem cells contains growth factors and has a promising prospect for use in regenerative medicine. In this study, the effects of marrow-derived stem cell-conditioned medium (MSC-CM) on bone regeneration after maxillary sinus floor elevation were examined in rabbits.

Materials And Methods: Rabbit bone marrow-derived stem cells (rMSCs) were cultured with MSC-CM for 48 hours, and their mobilization and proliferation were evaluated.

Effects of the permeability of shields with autologous bone grafts on bone augmentation.

Purpose: The objective of this study was to histologically evaluate and compare the effects of the permeability of shields on bone augmentation in a rabbit calvarial model.

Materials And Methods: Twelve adult male Japanese white rabbits were used for the study. Each received four titanium cylinders, which were placed into perforated slits made in the outer cortical bone of the calvaria and filled with autologous iliac bone.

Effects of self-assembling peptide hydrogel scaffold on bone regeneration with recombinant human bone morphogenetic protein-2.

Purpose: The objective of this pilot study was to histologically evaluate bone regeneration using a self-assembling peptide hydrogel scaffold with recombinant human bone morphogenetic protein-2 (rhBMP-2) in a rabbit calvaria model.

Materials And Methods: Five adult New Zealand White rabbits were used for the study. Each received four titanium cylinders, which were placed into perforated slits made in the outer cortical bone of the calvaria.

Effects of implant surface on bone healing around titanium screw implants in ovariectomized rats.

Purpose: The aim of this study was to investigate whether estrogen deficiency interrupts bone healing around titanium implants and to evaluate whether bone healing around implants under a condition of estrogen deficiency is affected by variations in implant surface characteristics.

Materials And Methods: Forty-eight female rats were divided into two groups: ovariectomized rats (OVX; n = 24) and sham-operated rats (SHAM; n = 24). Each group was further divided into two groups: a machine-polished implants group and a sandblasted implants group.

Stromal cell-derived factor-1 enhances distraction osteogenesis-mediated skeletal tissue regeneration through the recruitment of endothelial precursors.

Distraction osteogenesis (DO) is a unique therapy that induces skeletal tissue regeneration without stem/progenitor cell transplantation. Although the self-regeneration property of DO provides many clinical benefits, the long treatment period required is a major drawback. A high-speed DO mouse model (H-DO), in which the distraction was done two times faster than in control DO (C-DO) mice, failed to generate new bone callus in the DO gap.

An experimental study of bone healing around the titanium screw implants in ovariectomized rats: enhancement of bone healing by bone marrow stromal cells transplantation.

Purpose: : This study is to evaluate the bone quality of surrounding areas of implants with bone marrow stromal cells (BMSCs) transplantation to rat femur, which have become osteoporosis-induced models.

Materials And Methods: : The Sprague-Dawley rats were divided into 3 groups: the first group where their ovaries were removed (OVX group), the second group where a sham surgery was given (SHAM group), and the third group where BMSCs were transplanted to an OVX group (OVX-BMSCs group). In the OVX-BMSCs group, 1 × 10 BMSCs were transplanted into femur with implant.

Effects of cortical bone perforation on periosteal distraction: an experimental study in the rabbit mandible.

Purpose: To investigate tissue reactions using periosteal distraction with decorticating holes in a rabbit model.

Materials And Methods: Twenty-five Japanese white rabbits weighing 3.2 to 3.

Promoted new bone formation in maxillary distraction osteogenesis using a tissue-engineered osteogenic material.

Bilateral maxillary distraction was performed at a higher rate in rabbits to determine whether locally applied tissue-engineered osteogenic material (TEOM) enhances bone regeneration. The material was an injectable gel composed of autologous mesenchymal stem cells, which were cultured then induced to be osteogenic in character, and platelet-rich plasma (PRP). After a 5-day latency period, distraction devices were activated at a rate of 2.
