Thrombo-occlusive cerebrovascular disease resulting in stroke and permanent neuronal loss is an important cause of morbidity and mortality. Because of the unique properties of cerebral vasculature and the limited reparative capability of neuronal tissue, it has been difficult to devise effective neuroprotective therapies in cerebral ischemia. Our results(More)
Basophils express major histocompatibility complex class II, CD80 and CD86 and produce interleukin 4 (IL-4) in various conditions. Here we show that when incubated with IL-3 and antigen or complexes of antigen and immunoglobulin E (IgE), basophils internalized, processed and presented antigen as complexes of peptide and major histocompatibility complex(More)
We recently reported that a broad-spectrum caspase inhibitor zVAD-fmk failed, while p38 inhibitor SB203580 succeeded, to prevent chromatin condensation and nuclear fragmentation induced by hypoxia in tube-forming HUVECs. In this study, we investigated the reasons for zVAD-fmk's inability to inhibit these morphological changes at the molecular level. The(More)
We present a case of hepatosplenic sarcoidosis. A 51-year-old Japanese male, who was diagnosed to have sarcoidosis 4 years previously, was presented to our hospital because of dry cough and anorexia with weight loss. He had tender hepatosplenomegaly. A dynamic abdominal computed tomography (CT) revealed multiple small low-density areas in both liver and(More)
Malignant mesothelioma is an aggressive tumor of serosal surfaces, which is refractory to current treatment options. Arsenic trioxide (As2O3) is used clinically to treat acute promyelocytic leukemia, and also to inhibit proliferation of several solid tumors including hepatoma, esophageal, and gastric cancer in vitro. Here we found that As2O3 inhibited cell(More)
Hepatocyte growth factor (HGF) was reported to be effective in preventing acute graft-versus-host disease (GVHD) in a murine model. We examined serum HGF concentrations in 38 patients receiving allogeneic bone marrow transplants, and investigated the relationship of serum HGF concentrations to severity of acute GVHD. More HGF was present in sera from(More)
This study focuses on a possible role of intercellular adhesion molecule-1 (ICAM-1) in interstitial pulmonary diseases. We determined a soluble form of ICAM-1 in serum and bronchoalveolar lavage fluid (BALF) using ELISA in patients with usual interstitial pneumonia (UIP), bronchiolitis obliterance organizing pneumonia (BOOP), or nonspecific interstitial(More)
The CNS has the potential to marshal strong reparative mechanisms, including activation of endogenous neurogenesis, after a brain injury such as stroke. However, the response of neural stem/progenitor cells to stroke is poorly understood. Recently, neural stem/progenitor cells have been identified in the cerebral cortex, as well as previously recognized(More)
Immunological abnormalities (IA) are frequently observed in patients with myelodysplastic syndromes (MDS). Although there have been a number of analyses of the prognostic factors, there have been few studies, if any, to determine whether IA affects prognosis. We investigated the prognosis of 153 MDS patients with or without IA who were treated at a single(More)
Monoclonal antibodies were raised against rabbit platelet cytosolic arachidonoyl-preferential phospholipase A2. The antibodies precipitated the arachidonoyl-preferential phospholipase A2 activity in the soluble fraction of a rabbit platelet lysate in combination with an immobilized anti-mouse immunoglobulin antibody, and reacted predominantly with a protein(More)
