Heterotopic submandibular gland with herniation through the mylohyoid boutonnière: a unique radiological case.

Purpose: To describe a rare case of heterotopic submandibular gland (SMG) tissue herniating through the mylohyoid boutonnière into the anterior submandibular space, diagnosed using imaging, and to provide insights into its clinical implications.

Methods: A 59-year-old male with a history of smoking and type 2 diabetes presented with new-onset hoarseness. Imaging, including contrast-enhanced computed tomography (CT) and magnetic resonance imaging (MRI), was performed.

A Mindfulness-Based App Intervention for Pregnant Women: Study Design, Development, and Preliminary Testing of a Prototype.

Background: Pregnancy is a complex period characterized by significant transformations. How a woman adapts to these changes can affect her quality of life and psychological well-being. Recently developed digital solutions have assumed a crucial role in supporting the psychological well-being of pregnant women.

Biomechanical testing of virtual meniscus implants made from a bi-phasic silk fibroin-based hydrogel and polyurethane via finite element analysis.

Objective: To investigate the suitability of different material compositions and structural designs for 3D-printed meniscus implants using finite element analysis (FEA) to improve joint function after meniscal injury and guide future implant development.

Design: This experimental study involved in-silico testing of a meniscus model developed from two materials: a specially formulated hydrogel composed of silk fibroin (SF), gelatine, and decellularized meniscus-derived extracellular matrix (MD-dECM), and polyurethane (PU) with stiffness levels of 54 and 205 MPa. Both single-material implants and a two-volumetric meniscus model with an SF/gelatine/MD-dECM core and a PU shell were analysed using FEA to simulate the biomechanical performance under physiological conditions.

Insulin-degrading enzyme regulates insulin-directed cellular autoimmunity in murine type 1 diabetes.

Type 1 diabetes results from the destruction of pancreatic beta cells by autoreactive T cells. As an autoantigen with extremely high expression in beta cells, insulin triggers and sustains the autoimmune CD4 and CD8 T cell responses and islet inflammation. We have previously shown that deficiency for insulin-degrading enzyme (IDE), a ubiquitous cytosolic protease with very high affinity for insulin, induces endoplasmic reticulum (ER) stress and proliferation in islet cells and protects non-obese diabetic mice (NOD) from diabetes.
