CT navigation-assisted intraoral extraction of large submandibular gland stones: a minimally invasive approach.

Sialolithiasis is a common cause of salivary gland obstruction, leading to symptoms such as pain and swelling. In cases of intraparenchymal submandibular stones and proximal ductal stones larger than 7 mm, interventional sialendoscopy may fail, necessitating sialoadenectomy. As an alternative, intraoral stone extraction can be performed with CT-guided navigation.

Ring Magnet-Guided Magnetic Manipulation for Biofabrication of 3D Cellular Structures.

Negative magnetophoresis is employed to levitate cells in a paramagnetic medium without the need for magnetic labeling, preserving their natural state and minimizing toxicity. The single-ring magnet configuration that provides an open space in the levitation chamber enhances culture accessibility and scalability, enabling the formation of millimeter-sized 3D structures through cellular self-assembly. This system provides a versatile and cost-effective approach for diverse applications, including tissue engineering and biofabrication.

3D Cell Culture Models as a Platform for Studying Tumor Progression, Testing Treatment Responses, and Discovering Biomarkers.

In this chapter, we present a detailed protocol for establishing a three-dimensional (3D) multicellular tumor spheroids (MCTSs) model to simulate the tumor microenvironment (ME) associated with metabolic dysfunction-associated steatotic liver disease (MASLD) for the study of hepatocellular carcinoma (HCC) and colorectal cancer (CRC) cell aggressiveness, growth, and metastasis potential. The MASLD microenvironment (MASLD-ME) is recreated by embedding hepatic stellate cells in a collagen I matrix within a Boyden chamber system. The metabolic medium mimics MASLD conditions, enriched with high glucose, fructose, insulin, and fatty acids, to simulate metabolic stresses associated with the disease.

We aimed to reveal the relationship between PRAME expression and clinicopathologic parameters, immunologic markers, survival in melanomas.

Dystonia caused by ANO3 variants is due to attenuated Ca influx by ORAI1.

Background: Dystonia is a common neurological hyperkinetic movement disorder that can be caused by mutations in anoctamin 3 (ANO3, TMEM16C), a phospholipid scramblase and ion channel. We previously reported patients that were heterozygous for the ANO3 variants S651N, V561L, A599D and S651N, which cause dystonia by unknown mechanisms.

Methods: We applied electrophysiology, Ca measurements and cell biological methods to analyze the molecular mechanisms that lead to aberrant intracellular Ca signals and defective activation of K channels in patients heterozygous for the ANO3 variants.

Development of Biomimetic Substrates for Limbal Epithelial Stem Cells Using Collagen-Based Films, Hyaluronic Acid, Immortalized Cells, and Macromolecular Crowding.

Despite the promising potential of cell-based therapies developed using tissue engineering techniques to treat a wide range of diseases, including limbal stem cell deficiency (LSCD), which leads to corneal blindness, their commercialization remains constrained. This is primarily attributable to the limited cell sources, the use of non-standardizable, unscalable, and unsustainable techniques, and the extended manufacturing processes required to produce transplantable tissue-like surrogates. Herein, we present the first demonstration of the potential of a novel approach combining collagen films (CF), hyaluronic acid (HA), human telomerase-immortalized limbal epithelial stem cells (T-LESCs), and macromolecular crowding (MMC) to develop innovative biomimetic substrates for limbal epithelial stem cells (LESCs).
