Comprehensive analysis of risk factors for flap necrosis in free flap reconstruction of postoperative tissue defects in oral and maxillofacial tumors.

Free flap reconstruction for postoperative tissue defects in oral and maxillofacial tumors is a critical component of reconstructive surgery. Identifying risk factors for flap necrosis is essential for improving surgical outcomes and patient quality of life. A retrospective study was conducted on patients who underwent free flap reconstruction between January 2020 and December 2023.

Integrating Co(OH) nanosheet arrays on graphene for efficient noble-metal-free EY-sensitized photocatalytic H evolution.

The development of an efficient noble-metal-free cocatalyst is the key to photocatalytic hydrogen production technology. In this study, hierarchical Co(OH) nanosheet array-graphene (GR) composite cocatalysts are developed. With Eosin Y (EY) as a photosensitizer, the optimal Co(OH)-10%GR hybrid cocatalyst presents excellent photocatalytic activity with an H production rate of 17 539 μmol g h, and the apparent quantum yield for hydrogen production can reach 12.

CircRNA_0109291 regulates cell growth and migration in oral squamous cell carcinoma and its clinical significance.

Objectives: Circular RNAs (circRNAs), a new class of non-coding RNAs, have emerged as important regulators during tumorigenesis. However, the functions of circRNAs have not been completely clarified in the progression of cancers. In our study, a novel circRNA hsa_circ_0109291 was investigated in oral squamous cell carcinoma (OSCC) tissues and cell lines.

Salivary Circular RNAs Hsa_Circ_0001874 and Hsa_Circ_0001971 as Novel Biomarkers for the Diagnosis of Oral Squamous Cell Carcinoma.

Background/aims: Recent studies have demonstrated that circular RNAs (circRNAs) can serve as potential molecular markers for disease diagnosis. However, little is known about their diagnostic potential for oral squamous cell carcinoma (OSCC). This study aimed to determine the expression of circRNAs in the saliva of OSCC patients to identify novel biomarkers for OSCC screening.

[Finite element stress analysis of all-ceramic continuous crowns of the lower anterior teeth in differential shoulder thickness].

Purpose: To investigate the stress distributions under load in 3 types of all-ceramic continuous crowns of the lower anterior teeth with differential shoulder thickness.

Methods: Cone-beam CT (CBCT) was used to scan the in vitro mandibular central incisors, and achieve three-dimensional finite element model of all-ceramic continuous crowns with different shoulder width by using Mimics, Abaqus software. Different load conditions were simulated based on this model to study the effect of shoulder width variation on finite element analysis of 3 kinds of different all-ceramic materials of incisors fixed continuous crowns of the mandibular.

[Expression of microRNA-31 and its clinicopathologic significance in oral squamous cell carcinoma].

Objective: To investigate the expression of microRNA-31 and its association with clinicopathologic features in oral squamous cell carcinoma (OSCC).

Methods: The expression level of microRNA-31 in 62 cases of OSCC and matched non-tumor adjacent tissue specimens was examined using stem-loop real-time PCR. The relationship between the expression of microRNA-31 and its clinicopathologic features of OSCC was analyzed.
