General Information and Applications of Najuta Fenestrated Stent Grafts for Aortic Arch Aneurysms.

Endovascular stent graft repair was developed to minimize the invasiveness of open surgery for thoracic and abdominal aortic diseases. This approach involves covering the diseased segment with a stented artificial graft. However, in thoracic endovascular aortic repair (TEVAR) for aortic arch diseases, special consideration is needed to preserve the aortic arch vessels.

Current immunotherapy for thymic epithelial tumors: a narrative review.

Background And Objective: Thymic epithelial tumors (TETs) are the most common neoplasm of the prevascular mediastinal compartment and are characterized by their rarity and variable clinical presentation. The present study aimed to explore the current management of patients with TET with a special focus on immunotherapy for advanced disease.

Methods: Relevant studies published between 1981 and 2024 were searched in PubMed using search terms "Thymoma", "Thymic cancer", "Myasthenia gravis", "Radiation therapy", "Surgery", and "Immunotherapy".

Spatial transcriptome analysis of lung squamous cell carcinoma arising from interstitial pneumonia provides insights into tumor heterogeneity.

Interstitial pneumonia (IP) is a refractory disease that causes severe inflammation and fibrosis in the interstitium of the lungs, often resulting in the development of lung cancer (LC) during treatment. Previous studies have demonstrated that the prognosis of LC complicated by IP is inferior to that of LC without IP. It is therefore of the utmost importance to gain a deeper understanding of the heterogeneity of such tumors.

Cardiac Presynaptic Sympathetic Nervous Function Evaluated by Cardiac PET in Patients with Chronotropic Incompetence Without Heart Failure.

Chronotropic incompetence (CTI), the inability of the heart to increase its rate with increased activity, leads to exercise intolerance and predicts overall mortality. We previously reported that cardiac β-adrenergic receptor downregulation occurs in patients with CTI without heart failure (HF), indicating postsynaptic sympathetic nervous dysfunction. However, cardiac presynaptic sympathetic nervous system function in CTI is not fully understood.

Hypoxia drives the formation of lung micropapillary adenocarcinoma-like structure through hypoxia-inducible factor-1α.

Micropapillary adenocarcinoma (MPC) is an aggressive histological subtype of lung adenocarcinoma (LUAD). MPC is composed of small clusters of cancer cells exhibiting inverted polarity. However, the mechanism underlying its formation is poorly understood.
