BACKGROUND The angiotensin II (Ang II) type 1 (AT(1)) receptor is expressed in bone marrow (BM) cells, whereas it remains poorly defined how Ang II regulates differentiation/proliferation of monocyte-lineage cells to exert proatherogenic actions. METHODS AND RESULTS We generated BM chimeric apoE(-/-) mice repopulated with AT(1)-deficient (Agtr1(-/-)) or(More)
OBJECTIVE Bone marrow (BM)-derived endothelial progenitor cells (EPCs) and vascular smooth muscle progenitor cells (VPCs) contribute to neointima formation, whereas the angiotensin II (Ang II) type 1 receptor (AT(1))-mediated action on BM-derived progenitors remains undefined. METHODS AND RESULTS A wire-induced vascular injury was performed in the femoral(More)
Data regarding relationship between pulse pressure (PP) at admission and in-hospital outcome in patients with acute myocardial infarction (AMI) undergoing primary percutaneous coronary intervention (PCI) are still lacking. A total of 1413 primary PCI-treated AMI patients were classified into quintiles based on admission PP (<40, n = 280; 40–48, n = 276;(More)
The artifacts caused by various factors, EOG (electrooculogram), blink and EMG (electromyogram), in EEG (electroencephalogram) signals increase the difficulty in analyzing them. In addition, EEG signals containing artifacts often cannot be used in analyzing them. So, it is useful and indispensable to eliminate the artifacts from EEG signals. A neural(More)
Although cisplatin is indispensable for the chemotherapy treatment of many malignancies, cisplatin-associated thrombosis is attracting increasing attention. However, experience of primary percutaneous coronary intervention (PCI) and intravascular ultrasound imaging (IVUS) for coronary thrombosis, possibly due to cisplatin-based chemotherapy, has been(More)
A 97-year-old woman was provoked a convulsion after taking a new quinolone antibiotic drug Levofloxacin and a non-steroidal anti-inflammatory drug Loxoprofen. At a later time, she was suffered from severe chest pain. An electrocardiogram showed ST segment elevation in leads II, III and aVF, and T-wave inversion in leads V1 to V4. Coronary angiography(More)
BACKGROUND Data regarding the relationship between systolic blood pressure (SBP) at admission and in-hospital outcome in patients with acute myocardial infarction (AMI) undergoing primary percutaneous coronary intervention (PCI) are still lacking in Japan. METHODS AND RESULTS A total of 1475 primary PCI-treated AMI patients were classified into quintiles(More)
Data regarding clinical efficacy of thrombectomy in patients with acute myocardial infarction (AMI) have been still limited in Japan. Using the AMI-Kyoto Multi-Center Risk Study database, the clinical background characteristics, angiographic findings, primary percutaneous coronary intervention (PCI) results and in-hospital prognoses were retrospectively(More)
