Actual encounters of the kidney kind: Exploring 48 cases of renal collision tumors through the lens of literature.

Multiple tumors of different lineages merging into a single mass, termed collision tumors, are considered a rare phenomenon in the kidney. Tumor components, or partners, may be malignant (including metastatic disease), borderline, or benign. We report the largest cohort to date of 48 cases.

Maintenance of cell wall remodeling and vesicle production are connected in .

Pathogenic and nonpathogenic mycobacteria secrete extracellular vesicles (EVs) under various conditions. EVs produced by ( ) have raised significant interest for their potential in cell communication, nutrient acquisition, and immune evasion. However, the relevance of vesicle secretion during tuberculosis infection remains unknown due to the limited understanding of mycobacterial vesicle biogenesis.

Virtual Surgical Planning and Patient-Specific Instruments for Correcting Lower Limb Deformities in Pediatric Patients: Preliminary Results from the In-Office 3D Printing Point of Care.

(1) Background: Virtual reality and 3D printing are transforming orthopedic surgery by enabling personalized three-dimensional (3D) models for surgical planning and Patient-Specific Instruments (PSIs). Hospitals are establishing in-house 3D printing centers to reduce costs and improve patient care. Pediatric orthopedic surgery also benefits from these technologies, enhancing the precision and personalization of treatments.

Isolation of Bacterial Extracellular Vesicles and Identification of Their Protein Cargo.

Bacterial membrane vesicles (BMVs) are important effectors in the pathogenesis, virulence, and biofilm formation during different bacterial infections. Because of their structure, BMVs can be applied as drug delivery systems (DDS) or in the production of immunogenic vaccines against different untreated diseases. In this sense, different antigens or immune stimulator molecules, such as proteins can be extracted for the development of such vaccines.
