Empirical antifungal therapy is the current standard of care for patients with febrile neutropenia unresponsive to broad-spectrum antimicrobials. Although a number of antifungal agents are currently available, the need remains for effective but less toxic alternatives for this indication. We therefore conducted a phase 2 study of micafungin for 80 patients(More)
Hemophagocytic syndrome (HPS) induced by uncontrolled macrophage activation and subsequent graft failure is a frequent and prominent complication after allogeneic stem cell transplantation (allo-SCT), a cause of severe morbidity and death, and a therapeutic challenge. Liposome-incorporated dexamethasone, dexamethasone palmitate (DP), shows greater efficacy(More)
We have demonstrated that adipose tissue-derived mesenchymal stem cells (ADSCs) from mice are capable of reconstituting the hematopoietic microenvironment, and facilitate hematopoiesis more effectively than bone marrow-derived mesenchymal stem cells (BMSCs) in mouse. The ready accessibility of fat tissue rich in MSCs and the higher hematopoiesis-supporting(More)
CD20 is expressed in most B-cell lymphomas and is a critical molecular target of rituximab. Some B-cell lymphomas show aberrant CD20 expression, and rituximab use in these patients is controversial. Here we show both the molecular mechanisms and the clinical significance of de novo diffuse large B-cell lymphomas (DLBCL) that show a CD20 immunohistochemistry(More)
Prickle is known to be involved in planar cell polarity, including convergent extension and cell migration; however, the detailed mechanism by which Prickle regulates cellular functions is not well understood. Here, we show that Prickle1 regulates front-rear polarization and migration of gastric cancer MKN1 cells. Prickle1 preferentially accumulated at the(More)
In this paper, we propose a method for estimating object motion by three-dimensional scene flow using multiple cameras. The scene flow is regularized by applying sub-space constraints and then object motion is estimated using RANSAC estimation. Regularizing the scene flow using subspace constraints results in highly accurate scene flow because it eliminates(More)
In recent years,"the fluorescent imaging techniques"has made rapid advances, it has become possible to observe the dynamics of living cells in individuals or tissues. It has been considered that it is extremely difficult to observe the living bone marrow directly because bone marrow is surrounded by a hard calcareous. But now, we established a method for(More)
Osteoclasts are specialized polyploid cells that resorb bone. Upon stimulation with receptor activator of nuclear factor-κB ligand (RANKL), myeloid precursors commit to becoming polyploid, largely via cell fusion. Polyploidization of osteoclasts is necessary for their bone-resorbing activity, but the mechanisms by which polyploidization is controlled remain(More)
Multiphoton excitation microscopy (MPM) is regarded as an effective tool that enables the visualization of deep regions within living tissues and organs, with little damage. Here, we report novel non-labeling MPM (NL-MPM) imaging of fresh human colorectal mucosa, which is useful for discriminating cancer lesions from normal tissues quantitatively without(More)
