The following protocol describes the methodology for the acquisition and analysis of echocardiographic images used to obtain the Left Atrial Volume (LAV), Aorta (Ao) diameter, and Pulmonary Artery (PA) diameter in mice. This technique is a non-invasive, non-terminal procedure that allows assessment of the cardiopulmonary function.

We present a protocol used to discover an interactive effect between sleep and cortisol on memory consolidation, particularly for negative arousing images. Specifically, the experimental design utilizes eye tracking, salivary cortisol analysis, and behavioral memory testing – methods that can be used with both healthy and clinical participants.

Catheter-based Endovascular Angioplasty for Fibrosing Mediastinitis-associated Pulmonary Vein Stenosis
0 Views •
2025
Pulmonary vein stenosis (PVS) is a life-threatening complication of fibrosing mediastinitis (FM), with a poor prognosis if not properly treated. Currently, catheter-based endovascular angioplasty is a promising therapeutic strategy for FM-associated PVS. This protocol primarily outlines a stepwise approach to the transcatheter procedure for FM-associated PVS.

Marginating-pulmonary leukocytes exhibit unique characteristics and distinct immunological functions compared to other leukocyte populations. Here we describe selective harvesting of this subpopulation of pulmonary leukocytes, by forced perfusion of the lungs in rats and mice. Marginating-pulmonary leukocytes seem critical in determining susceptibility to blood-borne and lung-related diseases.

Hypoxic pulmonary vasoconstriction (HPV) is an important physiological phenomenon by which at alveolar hypoxia lung perfusion is matched to ventilation. The major vascular segment contributing to HPV is the intra-acinar artery. Here, we describe our protocol for the analysis of HPV of murine pulmonary vessels with diameters of 20-100 μm.
FAQs
Different alveolar contents point toward different clinical contexts. Fluid may occur with pulmonary edema, inflammatory cells with infection or inflammation, blood with pulmonary hemorrhage, and other material may occur with malignancy. These contents replace air, increasing radiographic density and potentially reducing ventilation and oxygenation. Identifying the likely content helps clinicians investigate the underlying cause rather than treating the image as a diagnosis.
Distribution provides important context for interpreting pulmonary consolidation. Clinicians consider where the finding appears together with symptoms and imaging characteristics, because these features help guide diagnostic evaluation and treatment of the underlying condition. The distribution therefore contributes to clinical reasoning without independently establishing whether infection, edema, hemorrhage, inflammation, or malignancy is responsible.
The distinction depends on interpreting the finding as an alveolar process rather than assuming that every area of increased lung density has the same origin. Pulmonary consolidation reflects disease affecting normally air-filled alveoli, whereas pleural effusion and atelectasis represent different diagnostic categories. Making this distinction helps clinicians select an appropriate evaluation for the underlying cause.
Evaluation combines clinical findings with imaging rather than relying on a single sign. Symptoms, oxygenation, crackles, bronchial breath sounds, the distribution of the abnormality, and features such as air bronchograms can all contribute. This integrated assessment helps clinicians determine whether the pattern is consistent with alveolar disease and guides further investigation of its cause.
Air bronchograms are an imaging feature that may accompany pulmonary consolidation and can support recognition of an alveolar abnormality. They should be interpreted alongside the distribution of the finding, associated symptoms, and other imaging observations. In that broader context, they contribute to distinguishing alveolar disease from conditions such as pleural effusion or atelectasis.
Recognition is useful when clinicians are evaluating possible infection, inflammation, pulmonary edema, hemorrhage, or malignancy. The finding can explain impaired ventilation, reduced oxygenation, and associated examination abnormalities, while its distribution and imaging appearance help direct diagnostic work. Treatment decisions then focus on the underlying condition responsible for the consolidation rather than on the radiologic finding alone.
