Light Weight Coarse Grid Aggregation for Smoothed Aggregation Algebraic Multigrid Solver

Autor: Akihiro Fujii, Teruo Tanaka, Kengo Nakajima

Publikováno v: IEEE Access, Vol 12, Pp 57345-57355 (2024)

The smoothed aggregation algebraic multigrid (SA-AMG) method is one of the most efficient linear solvers for large sized problems. It creates smaller-sized matrices, which is called “coarse level matrices”, from the problem matrix and the solutio

Effects of Human Deciduous Dental Pulp-Derived Mesenchymal Stem Cell-Derived Conditioned Medium on the Metabolism of HUVECs, Osteoblasts, and BMSCs

Autor: Ryo Kunimatsu, Tomoka Hiraki, Kodai Rikitake, Kengo Nakajima, Nurul Aisyah Rizky Putranti, Takaharu Abe, Kazuyo Ando, Ayaka Nakatani, Shuzo Sakata, Kotaro Tanimoto

Publikováno v: Cells, Vol 11, Iss 20, p 3222 (2022)

In this study, we assessed the effects of human deciduous dental pulp-derived mesenchymal stem cell-derived conditioned medium (SHED-CM) on the properties of various cell types. The effects of vascular endothelial growth factor (VEGF) in SHED-CM on t

The Influence of 2-Methacryloyloxyethyl Phosphorylcholine Polymer Materials on Orthodontic Friction and Attachment of Oral Bacteria

Autor: Ryo Kunimatsu, Yuji Tsuka, Kengo Nakajima, Keisuke Sumi, Yuki Yoshimi, Isamu Kado, Ayako Inada, Yoshihiro Kiritoshi, Kotaro Tanimoto

Publikováno v: Materials, Vol 15, Iss 16, p 5770 (2022)

There is no clinical evidence of the usage of 2-methacryloyloxyethyl phosphorylcholine (MPC) polymers in dental practice. We performed in vitro studies to determine whether the application of an MPC coating to stainless steel orthodontic wires confer

Combination of Carbonate Hydroxyapatite and Stem Cells from Human Deciduous Teeth Promotes Bone Regeneration by Enhancing BMP-2, VEGF and CD31 Expression in Immunodeficient Mice

Autor: Nurul Aisyah Rizky Putranti, Ryo Kunimatsu, Kodai Rikitake, Tomoka Hiraki, Kengo Nakajima, Takaharu Abe, Yuji Tsuka, Shuzo Sakata, Ayaka Nakatani, Hiroki Nikawa, Kotaro Tanimoto

Publikováno v: Cells, Vol 11, Iss 12, p 1914 (2022)

The objective of this study was to clarify the efficiency of a combination of stem cells from human deciduous teeth and carbonate apatite in bone regeneration of calvarial defects. Immunodeficient mice (n = 5 for each group/4 groups) with artificial

Dynamic imaging of the effect of mesenchymal stem cells on osteoclast precursor cell chemotaxis for bone defects in the mouse skull

Autor: Takaharu Abe, Keisuke Sumi, Ryo Kunimatsu, Nanae Oki, Yuji Tsuka, Kengo Nakajima, Kotaro Tanimoto

Publikováno v: Journal of Dental Sciences, Vol 13, Iss 4, Pp 354-359 (2018)

Background/purpose: Mesenchymal stem cells (MSCs) transplantation has previously been used in the field of regenerative medicine. Although bone regeneration is known to occur through the interaction between osteoblasts and osteoclasts, the effect of
