Simplified Fabrication of a Lingual Splint for Management of Mandibular Fractures.

Lingual splints have been used to treat mandibular fractures, particularly in cases of complicated mandibular fractures, and serve as a noninvasive adjunctive procedure for reduction and fixation. Furthermore, when used in conjunction with open reduction and internal fixation, the lingual splint provides feasible external fixation against displacing forces exerted by the robust musculature of the mandible. However, the conventional method for lingual splint fabrication is performed preoperatively, and the procedure is time-consuming.

Custom-Made Implant Fabrication for Chin Augmentation Using Piled-Up Expanded Polytetrafluoroethylene Sheets: An Innovative Surgical Technique and Literature Review.

Background: Alloplastic chin augmentation is the most common esthetic surgical treatment to reshape the chin. However, factory-made chin implants are typically standardized rather than custom-made and have potential to cause complications. Although the fabrication of custom-made implants by using computer-assisted planning and 3D-printing technology has become widespread, the process has several disadvantages, including long preoperative prosthesis preparation times, high costs, and unsuitability for patients with asymmetric chins or those who undergo combined mandibuloplasty before implant placement.

Associations of Rap1 with Cell Wall Integrity, Biofilm Formation, and Virulence in Candida albicans.

Rap1 (repressor activator protein 1) is a multifunctional protein, playing important roles in telomeric and nontelomeric functions in many eukaryotes. Candida albicans Rap1 has been previously shown to be involved in telomeric regulation, but its other functions are still mostly unknown. In this study, we found that the deletion of the gene altered cell wall properties, composition, and gene expression.

Periorbital Rejuvenation for Asians.

A primary concern in facial aesthetics is the rejuvenation of periorbital areas through soft tissue recontouring, skin texture improvement, and harmoniousness with souring anatomic tissues. Currently, the ease of harvesting, abundance in volume, and lack of immune rejection make autologous fat transplantation a disruptive strategy in aesthetic medicine. The evolution and improvements made by myriad surgeons have contributed to the popularity of periorbital rejuvenation and have highlighted its indispensability in Asian patients.

CD44 Promotes Breast Cancer Metastasis through AKT-Mediated Downregulation of Nuclear FOXA2.

The primary cause of breast cancer mortality is the metastatic invasion of cancerous stem cells (CSC). Cluster of differentiation 44 (CD44) is a well-known CSC marker in various cancers, as well as a key role player in metastasis and relapse of breast cancer. CD44 is a cell-membrane embedded protein, and it interacts with different proteins to regulate cancer cell behavior.

Comprehensive Transcriptomic and Proteomic Analyses Identify a Candidate Gene Set in Cross-Resistance for Endocrine Therapy in Breast Cancer.

Endocrine therapy (ET) of selective estrogen receptor modulators (SERMs), selective estrogen receptor downregulators (SERDs), and aromatase inhibitors (AIs) has been used as the gold standard treatment for hormone-receptor-positive (HR+) breast cancer. Despite its clinical benefits, approximately 30% of patients develop ET resistance, which remains a major clinical challenge in patients with HR+ breast cancer. The mechanisms of ET resistance mainly focus on mutations in the ER and related pathways; however, other targets still exist from ligand-independent ER reactivation.

ADSCs stimulated by resistin promote breast cancer cell malignancy via CXCL5 in a breast cancer coculture model.

The tumor microenvironment represents one of the main obstacles in breast cancer treatment owing to the presence of heterogeneous stromal cells, such as adipose-derived stem cells (ADSCs), that may interact with breast cancer cells and promote cancer development. Resistin is an adipocytokine associated with adverse breast cancer progression; however, its underlying mechanisms in the context of the breast tumor microenvironment remain largely unidentified. Here, we utilized a transwell co-culture model containing patient-derived ADSCs and breast cancer cell lines to investigate their potential interaction, and observed that breast cancer cells co-cultured with resistin-treated ADSCs (R-ADSCs) showed enhanced cancer cell growth and metastatic ability.

Foraging for the Optimal Dressing Scaffold to Carry Adipose-Derived Stromal/Progenitor Cells for Cell Therapy.
