Current in vitro models for gastric cancer research, such as 2D cell cultures and organoid systems, often fail to replicate the complex extracellular matrix (ECM) found in vivo. For the first time, this study utilizes a gelatin methacryloyl (GelMA) hydrogel, a biomimetic ECM-like material, in 3D bioprinting to construct a physiologically relevant gastric cancer model. GelMA's tunable mechanical properties allow for the precise manipulation of cellular behavior within physiological ranges.

Osteometric studies of the mandible are useful for identifying polymorphisms that are affected by general factors of anatomical variation, such as breed and gender, but age-related changes have not yet been reported in sheep. Our results showed that the morphometric parameters of the mandible were significantly affected by the age of the lambs. However, at 155 days of age, the mandible already presents all the morphological characteristics observed in adult animals.

Objective: We aimed to assess the impact of urinary diversion on survival in patients with advanced cervical cancer (CC) and hydronephrosis. Additionally, we examined the influence of other patient factors and urinary diversion type on survival.
Methods: A retrospective study analyzed survival in cervical cancer (CC) patients with hydronephrosis treated at two Mexican hospitals from 2011 to 2023.

Objectives: This study aimed to evaluate the diagnostic performance for medullary thyroid cancer (MTC) based on the 2017 Thyroid Imaging Reporting and Data System by the American College of Radiology (ACR TI-RADS) guideline, and the ability to recommend fine needle aspiration (FNA) for MTC.
Methods: Fifty-six MTCs were included, and 168 benign thyroid nodules (BTNs) and 168 papillary thyroid nodules (PTCs) were matched according to age. Ultrasound (US) features were reviewed according to ACR TI-RADS.

The differentiation between benign and malignant brain lesions remains a fundamental challenge in modern neuroimaging. This case highlights a rare presentation of ectatic Virchow-Robin spaces (VRS), which mimicked tumefactive brain lesions and required a comprehensive diagnostic evaluation to exclude neoplastic, infectious, and inflammatory processes. A 37-year-old female presented with progressive headache, cognitive impairment, and facial pain.
