The children were divided into an HC group (91 cases) and a non-HC group (156 cases) based on whether HC occurred after operation.

Reduced delay in diagnosis of odontogenic keratocysts with malignant transformation: A case report.

Background: In rare cases, odontogenic keratocysts (ODs) transform into squamous cell carcinoma. Intervals between the first attendance of a patient and the diagnosis of OD with malignant transformation vary from weeks to years. In this article, we report a case of malignancy derived from OD with a five-day delay in diagnosis.

Biomineralization Precursor Carrier System Based on Carboxyl-Functionalized Large Pore Mesoporous Silica Nanoparticles.

Bone and teeth are derived from intrafibrillarly mineralized collagen fibrils as the second level of hierarchy. According to polymer-induced liquid-precursor process, using amorphous calcium phosphate precursor (ACP) is able to achieve intrafibrillar mineralization in the case of bone biomineral in vitro. Therefore, ACP precursors might be blended with any osteoconductive scaffold as a promising bone formation supplement for in-situ remineralization of collagens in bone.

Objective: To evaluate the effectiveness and safety of internal heat-type acupuncture needle (IHTAN) the-rapy in the treatment of post-stroke shoulder pain in apopletic patients.

Methods: According to the random number table, 96 patients with post-stroke shoulder pain were divided into IHTAN group and warm needle moxibustion group (＝48 in each one). Jianyu (LI15), Jianliao (TE14), Jianzhen (SI9), Binao (LI14) and Ashi points (Extra) on the affected side were selected in the two groups.

[Short-term and long-term therapeutic effects of internal heat-type acupuncture needle therapy combined with acupoint injection of O for post-stroke shoulder pain].

Objective: To observe the short-term and long-term therapeutic effects of internal heat-type acupuncture needle (IHTAN) therapy combined with acupoint injection of Ofor post-stroke shoulder pain in apopletic patients.

Methods: Patients with post-stroke shoulder pain were divided into warm needle moxibustion ＋ acupoint injection group (29 cases), acupoint injection group (30 cases) and IHTAN＋acupoint injection group (29 cases) according to the random number table. For acupoint injection, O solution (3 mL, 30 µg/mL) was injected into Jianyu (LI15), Jianliao (SJ14), Jianzhen (LI9), Binao (LI14) and Ashi points (4-6 acupoints every time) on the affected side, once every other day for 4 weeks.

Bimodal antibacterial system based on quaternary ammonium silane-coupled core-shell hollow mesoporous silica.

Hollow mesoporous silica (HMS) have been extensively investigated as a biomaterial for drug delivery. The present study developed quaternary ammonium silane-grafted hollow mesoporous silica (QHMS) to create a metronidazole (MDZ) sustained delivery system, MDZ@QHMS, with bimodal, contact-kill and release-kill capability. The QHMS was assembled through a self-templating method.

Translation of a solution-based biomineralization concept into a carrier-based delivery system via the use of expanded-pore mesoporous silica.

Unlabelled: Mineralization of collagen fibrils using solution-based systems containing biomimetic analogs of matrix proteins to stabilize supersaturated calcium phosphate solutions have been predictably achieved in vitro. Solution-based systems have limitations when used for in-situ remineralization of human hypomineralized tissues because periodic replenishment of the mineralizing solution is infeasible. A carrier-based platform designed for delivering mineral precursors would be highly desirable.

Biomimetic Intrafibrillar Mineralization of Type I Collagen with Intermediate Precursors-loaded Mesoporous Carriers.

Limited continuous replenishment of the mineralization medium is a restriction for in-situ solution-based remineralization of hypomineralized body tissues. Here, we report a process that generated amine-functionalized mesoporous silica nanoparticles for sustained release of biomimetic analog-stabilized amorphous calcium phosphate precursors. Both two-dimensional and three-dimensional collagen models can be intrafibrillarly mineralized with these released fluidic intermediate precursors.

One-pot synthesis of antibacterial monomers with dual biocidal modes.

Objectives: The present study reported a method for preparing a blend of antibacterial quaternary ammonium silanes and quaternary ammonium methacryloxy silane (QAMS) based on the sol-gel reaction between dimethyldiethoxy silane and two trialkoxysilanes, one with an antibacterial quaternary ammonium functionality and the other with a methacryloxy functionality.

Methods: Reaction products of the sol-gel reaction were characterised by direct infusion mass spectrometry, FTIR and proton, carbon and silicon NMR. This blend of monomers was incorporated into an experimental universal adhesive for evaluation of antimicrobial activity against Streptococcus mutans biofilms, microtensile bond strength and cytotoxicty.

Permeability calculations in three-dimensional isotropic and oriented fiber networks.

Hydraulic permeabilities of fiber networks are of interest for many applications and have been studied extensively. There is little work, however, on permeability calculations in three-dimensional random networks. Computational power is now sufficient to calculate permeabilities directly by constructing artificial fiber networks and simulating flow through them.
