Influence of Graphene Oxide on the Mechanical Properties, Fracture Toughness, and Microhardness of Recycled Concrete.

There is a constant drive to improve the properties of recycled concrete owing to its inferior strength and fracture toughness compared to normal concrete and recent progress in graphene oxide (GO) nanomaterials impelling nanosized reinforcements to recycled concrete. Here, GO-modified natural sand (NS)- or recycled sand (RS)-based mortars (GONMs or GORMs) with six GO fractions (s) were fabricated to explore their 28 d mechanical strengths (, ), fracture toughness (, ), and microhardness (), as well as their crystal phases (using X-ray powder diffraction) and microstructures (using scanning electronic microscopy). Results reveal, greater enhancements in mechanical strengths (4.

Endoscope-assisted neurectomy and inferior alveolar nerve avulsion in treating trigeminal neuralgia.

Objective: To explore endoscope-assisted surgical treatment for idiopathic trigeminal neuralgia (TN), with neurectomy and avulsion of the inferior alveolar nerve (IAN), when patients are not willing to undergo intracranial procedures.

Clinical Materials And Methods: Five TN patients with inferior alveolar neuralgia in the mandibular branch were admitted; endoscope-assisted inferior alveolar neurectomy and avulsion was performed for TN treatment. Clinical observation and postoperative follow-up were conducted.

miR-1827 inhibits osteogenic differentiation by targeting IGF1 in MSMSCs.

We recently reported that maxillary sinus membrane stem cells (MSMSCs) have osteogenic potential. However, the biological mechanisms of bone formation remain unclear. In this study, we investigated the role and mechanisms of microRNAs (miRNAs) in the osteogenic differentiation of MSMSCs.

The preoperative platelet-lymphocyte ratio versus neutrophil-lymphocyte ratio: which is better as a prognostic factor in oral squamous cell carcinoma?

Objective: Recent studies have shown that the presence of systemic inflammation and platelet status correlate with poor survival in various cancers. The aim of this study was to evaluate the prognostic value of the preoperative platelet-lymphocyte ratio (PLR) and the neutrophil-lymphocyte ratio (NLR) in patients with oral squamous cell carcinoma (OSCC) undergoing surgery.

Methods: In this study, 306 patients with OSCC who had surgery were enrolled.

Treatment of a subtype of trigeminal neuralgia with descending palatine neurotomy in the pterygopalatine fossa via the greater palatine foramen-pterygopalatine canal approach.

Purpose: To discuss an effective surgical treatment of a subtype of trigeminal neuralgia with descending palatine neuralgia of the maxillary division.

Method: Nine patients, who suffered from trigeminal neuralgia with descending palatine neuralgia of the maxillary division, received neurotomy and avulsion of the descending palatine nerve in the pterygopalatine fossa via the greater palatine foramen-pterygopalatine canal approach. Seven of the patients had a recurrence of descending palatine neuralgia after they received treatment of maxillary neuralgia with neurotomy and avulsion of the infraorbital nerve; two patients were diagnosed with descending palatine neuralgia of the maxillary division in our department.

Knockdown of Cdc6 inhibits proliferation of tongue squamous cell carcinoma Tca8113 cells.

The present study aimed at evaluating the effects of Cdc6 downregulation on the proliferation of Tca8113 cells. Two lentiviral vectors (KD1 and KD2) expression cdc6 siRNA were constructed and then infected into Tca8113 cells. Real-time PCR and Western blot analysis were performed to detect the mRNA and protein expression of Cdc6.

Pulmonary metastases from an Ameloblastoma: case report and review of the literature.

Ameloblastomas have a high recurrence rate, and because of their biological tendency towards local invasion are considered borderline tumours. Despite this, reports of metastasis of these tumours are rare. This report presents a patient with mandibular ameloblastoma that recurred 29 years after surgery and metastasized to both lungs.

Spatio-temporal localization of HIF-1alpha and COX-2 during irradiation-induced oral mucositis in a rat model system.

Purpose: Oral mucositis is a common side effect of radiotherapy for head and neck cancer. The purpose of this study was to examine the significance of and the relationship between hypoxia inducible factor-1alpha (HIF-1alpha) and cyclooxygenase-2 (COX-2) gene expression and the corresponding protein levels in irradiated rat mucosa.

Material And Methods: A Sprague-Dawley rat model of irradiation-induced oral mucositis was generated.
