[The Result of Aortic Valve Plasty with Autologous Pericardium Using Sawazaki's Template].

The autologous pericardial aortic valve repair technique developed by Ozaki et al., using glutaraldehyde-treated autologous pericardium, has demonstrated superior durability to bioprosthetic valves. However, this technique has certain limitations, including excessive cusp height and cusp fluttering due to leaflet redunduncy.

Differences in Uniquely Identified Peptides Between ddaPASEF and diaPASEF.

Recent advancements in mass spectrometry-based proteomics have made it possible to conduct comprehensive protein analysis. In particular, the emergence of the data-independent acquisition (DIA) method powered by machine learning has significantly improved protein identification efficiency. However, compared with the conventional data-dependent acquisition (DDA) method, the degree to which peptides are uniquely identified by DIA and DDA has not been thoroughly examined.

[Mitral Valve Plasty for Complicated Lesions with Barlow-like Anterior Leaflet].

A 66 year-old male was admitted to our clinic suffering from dyspnea on effort. Cardio thoracic ratio (CTR) was 62%. Electrocardiogram showed atrial fibrillation.

[How to Repair the Bicuspid Aortic Valve Accompanying Regurgitation?].

We repaired the bicuspid aoric valve( BAV) with aortic regurgitation( AR) by bicuspidization. However, repaired fused cusp does not open full, and shows doming. Between 1997 and 2023 we repaired 30 BAV with AR.

A stress-reduced passaging technique improves the viability of human pluripotent cells.

Xeno-free culture systems have expanded the clinical and industrial application of human pluripotent stem cells (PSCs). However, reproducibility issues, often arising from variability during passaging steps, remain. Here, we describe an improved method for the subculture of human PSCs.

Total ankle arthroplasty for deformity of the foot in patients with rheumatoid arthritis using the TNK ankle system: clinical results of 21 cases.

We report the results of total ankle arthroplasty (TAA) of 21 ankle joints performed on 19 patients with rheumatoid arthritis (RA) using the Japanese TNK ankle system. The clinical evaluation for an average follow-up period of 33.8 months was based on the ankle analysis system.
