Tensile, compressive, and fatigue strength of a quasi-isotropic carbon fiber reinforced plastic laminate with a punched hole.

The mechanical properties of a quasi-isotropic carbon fiber reinforced plastic (CFRP) laminate with a punched hole were investigated. During the punching process, pressure was applied to the laminate through the upper and lower blank holders of a punching machine; the clearance between the punch and blank holders was set to be small to suppress damage in the CFRP laminates. Due to the dragging of plies encountered during punching, the surface of the punched hole was relatively uneven as compared to that of the drilled hole.

[Crista terminalis bridge mimicking right atrial mass; report of a case].

A 67-year-old female was operated upon because of transthoracic echocardiograms revealing a 13 x 8 mm mass in right atrium. However, there was no mass and was prominent crista terminalis (CT) instead. CT is the largest and strongest fibromuscular bundle in the right atrium, which separates primitive right atrium from the venous sinus.

Phylogeography of Hynobius yatsui (Amphibia: Caudata) in Kyushu, Japan.

The salamander Hynobius yatsui from southwestern Japan was formerly regarded as a small-sized group of H. naevius, but has recently been resurrected as a distinct species. We investigated the phylogeography of H.

Large organized thrombus of the tricuspid valve: report of a case.

We report the case of a 49-year-old woman with a large organized tricuspid valve thrombus in a structurally normal heart. Preoperative echocardiogram showed a large irregular-shaped mass, approximately 5 cm in diameter, moving from the right atrium into the right ventricle. The assumed preoperative diagnosis was cardiac metastasis of uterine sarcoma because she had undergone surgery for uterine sarcoma 15 years earlier.

Combination therapy for adult coronary artery aneurysm with off-pump coronary artery bypass grafting and vein graft-coated stent.

We report on a 51-year-old Japanese female with bilateral coronary artery aneurysms. Severe calcified aneurysms were detected in the proximal right coronary artery (RCA) and left anterior descending branch (LAD). The RCA was totally occluded and supplied by the blood flow via septal branches of the LAD.

Solitary skin metastasis after lung cancer resection.

A 75-year-old woman admitted for an abnormal chest X-ray shadow was found in transbronchial lung biopsy to have malignant cells. After right lower lobectomy with mediastinal lymph node dissection, pathological examination showed primary pulmonary squamous cell carcinoma (pT2N1M0, stage IIB). After discharge, we followed her up as an outpatient, with oral administration of uracil and futrafur (300 mg/day).

Endobronchial lipoma accompanied with primary lung cancer: report of a case.

A 72-year-old man was found to have an endobronchial lipoma accompanied with primary lung cancer. A left lower lobectomy with a mediastinal lymph node dissection and a sleeve resection of the lingual bronchus with telescoping bronchial anastomosis were done. The pathological staging was T1N2M0, stage IIIA.
