Comparison of two preserved cartilage iliac crest cortical-cancellous bone blocks graft harvesting techniques in children: A prospective, double-blind, randomized clinical trial.

Purpose: To compare donor-site morbidity for alveolar bone grafting results following cartilage-preserving outer and inner cortico-cancellous iliac crest (OCIC and ICIC) bone block grafting in children.

Materials And Methods: Patients were randomly divided into two groups and prospectively reviewed. In the OCIC and ICIC groups, cortico-cancellous bone blocks were harvested at outer and inner iliac crest respectively.

A New Luminescent Zn(II) Complex: Selective Sensing of CrO and Prevention Activity Against Orthodontic Root Absorption by Suppressing Inflammatory Response.

A novel luminescent coordination polymer (CP) based on Zn(II) ions as nodes [Zn(OPY)(Hbtc)] (1), [Hbtc = trimesic acid and OPY = 4,4'-(oxybis(4,1-phenylene))dipyridine] has been prepared via the solvothermal assembly of a tripodal multicarboxylic acid ligand, a bis-pyridyl ligand with V-shape containing two diverse coordination patterns as well as Zn ion. The experiments of photoluminescence also reflect that the coordination polymer 1 has high sensitivity to potassium dichromate, and its quenching efficiency is K of 2.12 × 10 L·mol.

Reciprocal regulation of miR-1254 and c-Myc in oral squamous cell carcinoma suppresses EMT-mediated metastasis and tumor-initiating properties through MAPK signaling.

Aim: This study aimed to determine the effect of miR-1254 on oral squamous cell carcinoma (OSCC) metastasis and the specific mechanism involved.

Methods: The metastatic properties of OSCC cells were analyzed by transwell assays. The tumor-initiating properties of OSCC cells were analyzed by tumor sphere formation assays.

Beta-nerve growth factor promotes neurogenesis and angiogenesis during the repair of bone defects.

We previously showed that the repair of bone defects is regulated by neural and vascular signals. In the present study, we examined the effect of topically applied β-nerve growth factor (β-NGF) on neurogenesis and angiogenesis in critical-sized bone defects filled with collagen bone substitute. We created two symmetrical defects, 2.

Effects of bone morphogenetic protein 2 gene therapy on new bone formation during mandibular distraction osteogenesis at rapid rate in rabbits.

Objective: We investigated the effect of recombinant human bone morphogenetic protein 2 (rhBMP-2) on new bone formation during rapid-rate mandibular distraction osteogenesis. We also explored the feasibility of using local BMP-2 gene therapy to compensate for bad callus formation caused by a rapid distraction rate.

Study Design: Bone marrow mesenchymal stem cells (MSCs) from Japanese rabbits were transfected with adenovirus (adv)-BMP-2.

[Effect on xenograft of nude mouse by combination therapy of nm23-H1 and protein-cisplatin].

Objective: To study the effect of protein-cisplatin and nm23-H1 therapy on the tumor of nude mouse.

Methods: The 15 BALB/C female mice were divided into three groups, control group, protein-cisplatin group and protein-cisplatin+nm23-H1 plasmid group. Tca8113 were injected into the mice subcutaneously with the concentration of 3.
