Association Between Anterior Knee Pain and Soft Tissue Gliding of the Anterior Knee Region After Total Knee Arthroplasty: A Cross-Sectional Study.

Objective(s): To investigate the relationship between impaired gliding in the anterior knee region and anterior knee pain (AKP) in patients after total knee arthroplasty (TKA).

Design: Cross-sectional study.

Setting: Orthopedic hospital.

Integrating Clay Modeling in Implant Fabrication for Craniofacial Defect.

Manufacturing craniofacial implants using 3-dimensional (3D) methods and computed tomography data has become popular. The image object for the defect is produced as the first step, followed by several methods to create the implant. The authors have used a novel method that combines clay modeling with 3D scanning to create implants for craniofacial contour reconstruction.

Alar base symmetry in orthognathic surgery: Patients with unilateral cleft.

Background: Patients with unilateral cleft lip and palate (UCLP) could present with a notable nasal deformity with alar base retrusion, which should be considered when planning orthognathic surgery (OGS).

Methods: This retrospective study included 84 patients with Class III malocclusion. Cone beam computed tomographic data were used for the investigation.

Overstretching alveolar epithelial type II cells decreases surfactant secretion via actin polymerization and intracellular trafficking alteration.

Pulmonary surfactant is essential for maintaining proper lung function. Alveolar epithelial type II (AE2) cells secrete surfactants via lamellar bodies (LBs). In tidal loading during each breath, the physiological cyclic stretching of AE2 cells promotes surfactant secretion.
