A combined experimental-computational approach for retinal characterization.

Subretinal injection of gene products is the only treatment option for inherited retinal diseases. However, this procedure induces localized high multiaxial deformations, potentially causing irreversible tissue damage due to retinal overstretching and tearing. Comprehensive characterization of retinal mechanical behavior is essential for performing safe injections.

3D bioprinting of multi-layered segments of a vessel-like structure with ECM and novel derived bioink.

3D-Bioprinting leads to the realization of tridimensional customized constructs to reproduce the biological structural complexity. The new technological challenge focuses on obtaining a 3D structure with several distinct layers to replicate the hierarchical organization of natural tissues. This work aims to reproduce large blood vessel substitutes compliant with the original tissue, combining the advantages of the 3D bioprinting, decellularization, and accounting for the presence of different cells.

Chondroblastoma-like osteosarcoma: a clinicopathological and molecular study of a rare osteosarcoma variant.

Objective: Chondroblastoma-like osteosarcoma (CBLOS) is a rare and poorly understood variant of OS. We examined the clinicopathological, immunohistochemical and molecular features of six CBLOSs to highlight the differences with conventional high-grade OS (CHGOS) and CB, including CB with aggressive features.

Methods: We performed histone 3.

Intraductal prostate cancer: An aggressive subset of prostate cancers? Immunophenotypic evaluation.

Introduction: The presence of intraductal prostate cancer in a sample is often associated with large tumor volume, an advanced stage of the disease, a high Gleason score and an increased risk of recurrence, and resistance to androgen suppression and chemotherapy, which are also correlated with reduced progression-free survival and with postoperative, biochemical relapse.

Methods: The aim of our study was to investigate whether carbonic anhydrase IX (CA IX) is upregulated in prostate cancer and to investigate ERG and EZH2 as potential markers for cancer aggression in aggressive acinar disease with intraductal component prostate cancer. The series consisted of 79 cases of prostate cancer.

Sclerosing Paragangliomas: Correlations of Histological Features with Patients' Genotype and Vesicular Monoamine Transporter Expression.

Paragangliomas and pheochromocytomas are rare neuroendocrine tumors, carrying a germ-line mutation in 40% patients. Sclerosis is a rare histological feature in these tumors. We investigated the possible correlations between histological findings, first sclerosis, immunoreactivity for vesicular catecholamine transporters (VMAT1/VMAT2) and patients' genotype in a consecutive series of 57 tumors (30 paragangliomas and 27 pheochromocytomas) from 55 patients.
