    Rod-packing arrangements of invariant tori in solenoidal vector fields with cubic symmetries

    The arrangements of invariant tori that resemble rod packings with cubic symmetries are considered in three-dimensional solenoidal vector fields. To find them systematically, vector fields whose components are...

    Comparison of clonal architecture between primary and immunodeficient mouse-engrafted acute myeloid leukemia cells

    Patient-derived xenografts (PDX) are widely used as human cancer models. Previous studies demonstrated clonal discordance between PDX and primary cells. However, in acute myeloid leukemia (AML)-PDX models, the...

    Identification of Meflin as a Potential Marker for Mesenchymal Stromal Cells

    Bone marrow-derived mesenchymal stromal cells (BM-MSCs) in culture are derived from BM stromal cells or skeletal stem cells. Whereas MSCs have been exploited in clinical medicine, the identification of MSC-spe...

    Clinical usefulness of WT1 mRNA expression in bone marrow detected by a new WT1 mRNA assay kit for monitoring acute myeloid leukemia: a comparison with expression of WT1 mRNA in peripheral blood

    We have previously shown the clinical usefulness of Wilms’ tumor 1 gene (WT1) mRNA expression in peripheral blood (PB) as a minimal residual disease (MRD) monitoring marker in 191 acute myeloid leukemia (AML) ...

    Lymphopenia following the completion of first-line therapy predicts early relapse in patients with diffuse large B cell lymphoma

    Early relapse is a parameter that affects clinical outcomes in relapsed diffuse large B cell lymphoma (DLBCL). The prognostic value of lymphopenia following the completion of first-line therapy and the relatio...

    An integral transform whose kernel is a stream function of a steady Euler flow with axisymmetry

    A new integral transform whose kernel is a Stokes stream function of an exact solution to the axisymmetric stationary Euler equations is derived with its inverse by using a Coulomb wave function. In the proces...

    Construction of solutions to the two-dimensional stationary Euler equations by the pseudo-advection method

    The finite difference approximation of a nonstationary pseudo-advected vorticity equation is proved to yield generalized solutions to the two-dimensional stationary Euler equations with nonvanishing vorticity....

    Solvability of the localized induction equation for vortex motion

    The initial and the initial-boundary value problems for the localized induction equation which describes the motion of a vortex filament are considered. We prove the existence of solutions of both problems glo...

    Synthesis and Photoregulated Metal Coordination of Azobenzene Polymer Having Ion Binding Sites

    Vinyl polymers having pendant 3,3′-substituted azobenzene were synthesized. Selective metal extracting ability was found in the photoisomerized polymers having bisiminodiacetic acid groups. The selectivity was...
