Different effects of catheter ablation on exercise tolerance, leg strength, and quality of life in paroxysmal versus persistent atrial fibrillation.

Background: Catheter ablation (CA) can improve exercise tolerance and quality of life (QOL) in patients with atrial fibrillation (AF). However, its differential effects on muscle strength between paroxysmal AF (PAF) and nonparoxysmal AF (Non-PAF) remain unclear.

Methods: We evaluated 94 patients (67.

Reoperation of Pulmonary Artery Intimal Sarcoma for Recurrence After Pulmonary Artery Replacement.

Pulmonary artery intimal sarcoma has very poor prognosis, for which radical resection may be difficult. A 68-year-old man with pulmonary artery intimal sarcoma underwent bilateral pulmonary artery resection and replacement. At 31 months postoperatively, recurrence occurred at the anastomotic site of the right pulmonary artery.

Generation of a transgenic chicken line with reporters for limb bud mesenchyme and apical ectodermal ridge cells.

Cell type-specific reporter transgenic chicken lines are invaluable tools in developmental biology, allowing the visualization of dynamics and differentiation states of target cell types in living embryos. Here, we report the establishment of a new transgenic chicken line in which limb mesenchyme and apical ectodermal ridge (AER) cells are labeled with different fluorescent proteins in the embryos. The processes for generating the reporter line involved using tissue-specific promoters, the Tol2 transposon-mediated genomic integration, and clonal culture system of primordial germ cells.

Successful Salvage of Four Cases of Unresectable Papillary Thyroid Cancer Following Lenvatinib Administration.

Background/aim: The role of lenvatinib as neoadjuvant chemotherapy for patients with advanced thyroid cancer has not been firmly established. In some cases, surgery may be considered when lenvatinib treatment becomes challenging to continue.

Case Report: We present four cases of unresectable thyroid cancer diagnosed histologically as papillary carcinoma.
