Preparation and Characterization of Nano-FeO and Its Application for C18-Functionalized Magnetic Nanomaterials Used as Chromatographic Packing Materials.

A new type of magnetic nanomaterial with FeO as the core and organic polymer as the shell was synthesized by seed emulsion polymerization. This material not only overcomes the problem of insufficient mechanical strength of the organic polymer, it also solves the problem that FeO is prone to oxidation and agglomeration. In order to make the particle size of FeO meet the requirement of the seed, the solvothermal method was used to prepare FeO.

Comparative Outcomes of Block and Cancellous Iliac Bone Grafting in Older Unilateral Alveolar Cleft Patients.

Objective: To compare osseous outcomes of block and cancellous iliac bone grafting in older unilateral alveolar cleft patients.

Design: Retrospective and observational follow-up study.

Setting: Cleft Lip and Palate Centre, Department of Oral and Maxillofacial Surgery, Affiliated Hospital of Stomatology, Nanjing Medical University, China.

Inactivation of RUNX3 protein expression in tongue squamous cell carcinoma and its association with clinicopathological characteristics.

The function of runt‑related transcription factor 3 (RUNX3) in oral cancer remains controversial. The present study aimed to determine the status of RUNX3 protein expression and its association with clinicopathological characteristics in tongue squamous cell carcinomas (SCC). The present study used three pairs of tongue SCC and non‑cancerous tissues to assess RUNX3 protein expression by western blot analysis, and two tongue SCC cell lines to determine RUNX3 protein localization by immunofluorescence and immunocytochemistry.

RUNX3 plays a tumor suppressor role by inhibiting cell migration, invasion and angiogenesis in oral squamous cell carcinoma.

Although aberrant expression of Runt-related transcription factor 3 (RUNX3) contributes to tumor progression and metastasis in a number of carcinomas, the status of RUNX3 and its correlation with prognosis in oral squamous cell carcinomas (OSCC) are still controversial. The aim of present study was to investigate the function of RUNX3 in OSCC and the underlying molecular mechanisms. Tissue microarray (TMA) consisting of 232 OSCC specimens was used to detect the expression of RUNX3 by immunohistochemistry method.

Anatomical Study and Clinical Application of Facial Artery Perforator Flaps in Intraoral Reconstruction: Focusing on Venous System.

Purpose: Facial artery perforator flaps (FAPFs) are preferred for the repair of intraoral and peri-nasal defects because it is a convenient procedure with minimal donor-site morbidity. The purpose of this study was to investigate the anatomic features of FAPFs and present their clinical application in intraoral reconstruction.

Materials And Methods: Five cadaver specimens (10 sides) of the head and neck region and 90 clinical cases (90 sides) of neck dissection were analyzed to explore the facial venous drainage system of FAPFs.

Short-term effects of repetitive transcranial magnetic stimulation on sleep bruxism - a pilot study.

The purpose of this study was to investigate the effects of repetitive transcranial magnetic stimulation (rTMS) on patients with sleep bruxism (SB). Twelve patients with SB were included in an open, single-intervention pilot study. rTMS at 1 Hz and an intensity of 80% of the active motor threshold was applied to the 'hot spot' of the masseter muscle representation at the primary motor cortex bilaterally for 20 min per side each day for 5 consecutive days.

Computer-aided design-based preoperative planning of screw osteosynthesis for type B condylar head fractures: A preliminary study.

Objective: To investigate the clinical application of a new computer-aided design - (CAD) based planning method for the treatment of type B condylar head fractures without fragmentation.

Methods: A total of 13 adult patients (19 sides) with type B condylar head fractures were included in the study. In all cases, imaging was performed using cone bean computed tomography (CBCT) preoperative, and Digital Imaging and Communications in Medicine (DICOM) files were imported into Simplant 11.

Accurate Evaluation of Cone-Beam Computed Tomography to Volumetrically Assess Bone Grafting in Alveolar Cleft Patients.

Objective: The aim of this study was to investigate the accuracy of cone-beam computed tomography (CBCT) to assess the volume of bone graft in alveolar cleft patients.

Materials And Methods: Twelve patients of unilateral alveolar cleft were included in this study. All patients were taken CBCT preoperative and 1 week postoperative.

A new design of facial artery perforator flaps for the reconstruction of small- to medium-sized intraoral defects.

Aim: The aim of this study was to investigate the reliability and outcomes of a new design of facial artery perforator flaps, extending from the angle of the mouth to the border of the mandible, for the reconstruction of small- to medium-sized intraoral defects.

Patients And Methods: The technique had been used in 23 patients between February 2009 and August 2012. The locations of intraoral defects included the tongue, the floor of the mouth, the inferior gingival mucosa, and the sublingual gland.

A novel two-dimensional metal-organic supramolecular framework including π-π stacking and hydrogen-bond interactions.

[μ-N,N'-Bis(pyridin-3-yl)benzene-1,4-dicarboxamide-1:2κ(2)N:N']bis{[N,N'-bis(pyridin-3-yl)benzene-1,4-dicarboxamide-κN]diiodidomercury(II)}, [Hg2I4(C18H14N4O2)3], is an S-shaped dinuclear molecule, composed of two HgI2 units and three N,N'-bis(pyridin-3-yl)benzene-1,4-dicarboxamide (L) ligands. The central L ligand is centrosymmetric and coordinated to two Hg(II) cations via two pyridine N atoms, in a syn-syn conformation. The two terminal L ligands are monodentate, with one uncoordinated pyridine N atom, and each adopts a syn-anti conformation.
