Multiscale Three-Dimensional Evaluation and Analysis of Murine Lung Vasculature From Macro- to Micro-Structural Level.

The pulmonary vasculature plays a pivotal role in the development and progress of chronic lung diseases. Due to limitations of conventional two-dimensional histological methods, the complexity and the detailed anatomy of the lung blood circulation might be overlooked. In this study, we demonstrate the practical use of optical serial block face imaging (SBFI), ex vivo microcomputed tomography (micro-CT), and nondestructive optical tomography for visualization and quantification of the pulmonary circulation's 3D architecture from macro- to micro-structural levels in murine lung samples.

Visualisation and quantification of subcutaneous injections of different volumes, viscosities and injection rates: An ex-vivo micro-CT study.

The effects of subcutaneous (SC) injection parameters such as drug formulation volume, viscosity and injection rate on therapeutic performance and tolerability have not been established for any drug product. In this study four groups of SC injections were performed on fresh ex vivo minipig abdominal tissue samples, varying volume (0.5-1 mL), viscosity (1-11 cP) and rate (0.

Differential pulmonary toxicity and autoantibody formation in genetically distinct mouse strains following combined exposure to silica and diesel exhaust particles.

Background: Inhalation of airborne particulate matter, such as silica and diesel exhaust particles, poses serious long-term respiratory and systemic health risks. Silica exposure can lead to silicosis and systemic autoimmune diseases, while DEP exposure is linked to asthma and cancer. Combined exposure to silica and DEP, common in mining, may have more severe effects.

The Immunopathology of Pulmonary Rejection after Murine Lung Transplantation.

To improve outcomes following lung transplantation, it is essential to understand the immunological mechanisms that result in chronic graft failure. The associated clinical syndrome is termed chronic lung allograft dysfunction (CLAD), which is known to be induced by alloimmune-dependent (i.e.
