[Long-term results of open stent-grafting applied with a Matsui-Kitamura( MK) stent in treatment of arch aneurysm].

We report the initial and long-term results of open stent-grafting (OSG) applied with a Matsui-Kitamura (MK) stent in the treatment of thoracic aortic aneurysm (TAA). From August 2005 to March 2013, OSG for TAA was applied in 46 cases( male/female, 36/10, 54-86 years old, mean age 71). During deep hypothermic circulatory arrest with antegrade selective cerebral perfusion, stent graft was delivered through the transected proximal aortic arch, followed by arch replacement with a 4-branched prosthesis.

[Open stent-grafting using the Matsui-Kitamura stent for a distal arch aneurysm; an idea for insertion of stent graft and organ protection].

For the improvement in the clinical results of open stent-grafting, the development of a device system and prevention of spinal cord injury are important. For that reasons, we devised 2 methods for the open stent-grafting with the Matsui-Kitamura (MK) stent. First, the applicator using transesophagial echo transducer cover made insertion of the stent-graft system easy and safe.

Production of trout offspring from triploid salmon parents.

Many salmonids have become at risk of extinction. For teleosts whose eggs cannot be cryopreserved, developing techniques other than egg cryopreservation to save genetic resources is imperative. In this study, spermatogonia from rainbow trout were intraperitoneally transplanted into newly hatched sterile triploid masu salmon.

Mesenchymal progenitors able to differentiate into osteogenic, chondrogenic, and/or adipogenic cells in vitro are present in most primary fibroblast-like cell populations.

MSCs and mesenchymal progenitor cells (MPCs) are studied for their potential in regenerative medicine. MSCs in particular have great potential, because various reports have shown that they can differentiate into many different cell types. However, the difference between mesenchymal stem/progenitor cells and so-called fibroblasts is unclear.

Quiescent string dominance parameter F and classification of one-dimensional cellular automata.

The classification of rules may be one of the most fundamental targets in the study of cellular automata. In this paper, we propose a method for achieving such a classification, in which a new quiescent string dominance parameter F, which is orthogonal to lambda, is introduced. For N -neighbor and K -state cellular automata, in the region 1/K View Article and Find Full Text PDF
