3D printing nacre powder/sodium alginate scaffold loaded with PRF promotes bone tissue repair and regeneration.

Bone defects are a common complication of bone diseases, which often affect the quality of life and mental health of patients. The use of biomimetic bone scaffolds loaded with bioactive substances has become a focal point in the research on bone defect repair. In this study, composite scaffolds resembling bone tissue were created using nacre powder (NP) and sodium alginate (SA) through 3D printing.

Zero-Strain Na V (PO ) F @Rgo/CNT Composite as a Wide-Temperature-Tolerance Cathode for Na-Ion Batteries with Ultrahigh-Rate Performance.

Sodium-ion batteries (SIBs) are widely considered a hopeful alternative to lithium-ion battery technology. However, they still face challenges, such as low rate capability, unsatisfactory cycling stability, and inferior variable-temperature performance. In this study, a hierarchical Na V (PO ) F (NVPF) @reduced graphene oxide (rGO)/carbon nanotube (CNT) composite (NVPF@rGO/CNT) is successfully constructed.

Three dimensional condylar positional and morphological changes following mandibular reconstruction based on CBCT analysis: a prospective study.

Objective: This study aimed to evaluate the condylar positional changes following mandibular reconstruction with preservation of the condylar head using Cone-Beam Computed Tomography (CBCT). Also, to assess joint space changes and the overall volumetric space compared to the preoperative status.

Methodology: This prospective study included 30 patients (60 joints) subjected to unilateral mandibular resection and reconstruction with preservation of the condylar head.

Evolutionary dynamics of codon usages for peste des petits ruminants virus.

Peste des petits ruminants virus (PPRV) is an important agent of contagious, acute and febrile viral diseases in small ruminants, while its evolutionary dynamics related to codon usage are still lacking. Herein, we adopted information entropy, the relative synonymous codon usage values and similarity indexes and codon adaptation index to analyze the viral genetic features for 45 available whole genomes of PPRV. Some universal, lineage-specific, and gene-specific genetic features presented by synonymous codon usages of the six genes of PPRV that encode N, P, M, F, H and L proteins reflected evolutionary plasticity and independence.

Dispersion of synonymous codon usage patterns in hepatitis E virus genomes derived from various hosts.

Hepatitis E virus (HEV) is an important zoonotic pathogen infecting a wide range of host species. It has a positive-sense, single-stranded RNA genome encoding three open reading frames (ORFs). Synonymous codon usages of viruses essentially determine their survival and adaptation to susceptible hosts.

Superficial parotidectomy with or without great auricular nerve preservation. Is there a difference in postoperative sensory recovery rates and quality of life?

The clinical implications of great auricular nerve (GAN) preservation or sacrifice during parotid surgery have long been a topic of controversy. This study aimed to compare sensory recovery rates and quality of life (QoL) in patients who had undergone superficial parotidectomy and had their GAN preserved or sacrificed. Fifty patients were prospectively analysed, 28 with the GAN preserved, and 22 with it sacrificed.

Evaluation of the postoperative effect of computer-assisted free fibula mandibular reconstruction.

Objectives: This study aims to establish a standardized, repeatable, and simple digital evaluation method for accurately determining the effect of computer-assisted free fibula mandibular reconstruction.

Methods: A total of 20 mandibular defect cases caused by tumors were analyzed retrospectively. The coronal, sagittal, and axial mandibular angles were measured and analyzed with Mimics Research 21.

Acellular dermal matrix for prevention of Frey's syndrome after superficial parotidectomy of benign tumors.

Purpose: To evaluate: 1) the efficacy of acellular dermal matrix (ADM) to prevent Frey's syndrome (FS) after superficial parotidectomy of benign tumors. 2) the effect of different follow-up intervals on the incidence of FS.

Methods: Fifty-five patients with benign parotid gland tumors underwent superficial parotidectomy were divided into two groups: Non-ADM group (n = 31, 56.

T-regulatory cell/T helper 17 cell imbalance functions as prognostic biomarker of oral squamous cell carcinoma - CONSORT.

Background: The role of T cells in the pathogenesis of oral squamous cell carcinoma (OSCC) was clarified by examining the levels of differentiated CD4CD25FOXP3 T-regulatory cells (Treg cells) and CD4+IL17+ T helper 17 (Th17) cells in OSCC patients.

Methods: Flow cytometry was conducted to measure the proportions of Treg/Th17 cells in different sample groups to identify a proper maker indicative of the progression and prognosis of OSCC.

Results: The results showed that a higher Treg/Th17 ratio led to poorer prognosis.

The effects of synonymous codon usages on genotypic formation of open reading frames in hepatitis E virus.

Hepatitis E virus (HEV) infection has emerged as an important public health issue. As a zoonotic RNA virus, new strains are continuously discovered from human or various animal species. However, the capability of cross-species infection varies largely among different strains.

Comparison of temporomandibular joint function and morphology after surgical and non-surgical treatment in adult condylar head fractures.

Purpose: The aim of this study was to evaluate whether surgical treatment can distinctly improve temporomandibular joint (TMJ) function and morphology in adult patients with condylar head fractures (CHFs) when compared with conservative treatment.

Patients And Methods: A retrospective study was performed to evaluate surgical and conservative outcomes in all patients who had suffered CHFs. In this study, all patients were divided into a surgical group and a conservative group.

MTFP1 overexpression promotes the growth of oral squamous cell carcinoma by inducing ROS production.

Mitochondrial fission process 1 (MTFP1) is a novel nuclear-encoded protein that promotes mitochondrial fission. Increasing lines of evidence indicate that increased mitochondrial fission is involved in carcinogenesis and tumor progression. However, the expression and biological effects of MTFP1 in cancer development is still unclear, especially in oral squamous cell carcinoma (OSCC).

The potential role of COX-2 in cancer stem cell-mediated canine mammary tumor initiation: an immunohistochemical study.

Additionally, it is becoming apparent that cyclooxygenase (COX) signaling is associated with canine mammary tumor development. The goals of the present study were to investigate COX-2 expression patterns and their effect on CSC-mediated tumor initiation in primary canine mammary tissues and tumorsphere models using immunohistochemistry.
