Thiazolidinediones are insulin-sensitizing drugs, ligands for peroxisome proliferator-activated receptor-γ (PPAR-γ), which play an important role in the modulation of inflammatory responses. Myocardial ischemia/reperfusion (MI/R) injury is associated with inflammation, in which various cells, particularly monocytes and macrophages, are involved. This study(More)
A recent study has shown that amiodarone inhibits the production of cytokines in vitro. This study was performed to examine the effects of amiodarone on survival, heart weight-to-body-weight ratio (HW/BW), myocardial lesions and cytokines production in a murine model of viral myocarditis induced by the encephalomyocarditis virus (EMCV). Four-week-old male(More)
Laguerre-Gaussian (LG) beams of various higher-order radial modes are generated by using a reflective phase-only liquid crystal on silicon (LCOS) spatial light modulator (SLM). Because of the LCOS SLM's phase-modulation characteristic of a wide spatial bandwidth, a phase modulation scheme effectively generates higher-order LG beams of up to the fifth-order(More)
BACKGROUND Recently, we screened for cardiac genes induced by metabolic stress and identified neural cell adhesion molecule (NCAM) as a candidate. This study aimed to clarify the expression pattern of NCAM in human cardiomyopathy. METHODS AND RESULTS A total of 64 cardiac tissue samples of patients with dilated cardiomyopathy were dichotomized according(More)
OBJECTIVE We previously demonstrated that fasciitis is a common lesion of dermatomyositis (DM) that is detectable early after disease onset by en bloc muscle biopsy combined with magnetic resonance imaging (MRI). Power Doppler ultrasonography (PDUS) is a useful method for detection of inflammation and vascularity in rheumatic diseases. We undertook this(More)
Massively parallel femtosecond laser processing with more than 1000 beams was demonstrated. Parallel beams were generated by a computer-generated hologram (CGH) displayed on a spatial light modulator (SLM). The key to this technique is to optimize the CGH in the laser processing system using a scheme called in-system optimization. It was analytically(More)
BACKGROUND Prokineticin 2 (PK2) expression is upregulated in mice with collagen-induced arthritis (CIA), an animal model of rheumatoid arthritis. The purpose of our study was to investigate the effects of PK2 inhibition on CIA. METHODS PK2, prokineticin receptor (PKR) 1, and PKR2 mRNA transcripts in the joints of CIA mice were measured by real-time PCR on(More)
To investigate whether microvascular lesions are present in the skin of patients with chronic congestive heart failure (CHF), skin biopsies were performed at the time of cardiac catheterization, and the results were compared with control subjects. The diagnosis of CHF was done by cardiac catheterization with reference to the elevation of plasma levels of(More)
Elevated levels of circulating tumor necrosis factor (TNF)-α have been reported in patients with decreased left ventricular ejection fraction. Also, TNF has been reported to depress myocardial contractility. In our previous study, no correlation was found between the plasma level of TNF and clinical parameters in patients with cardiomyopathy. In the present(More)
PURPOSE To investigate whether interleukin 10 (IL10) gene polymorphisms are associated with the development of sarcoidosis in Japanese patients. METHODS Two hundred and eighty-eight Japanese sarcoidosis patients and 310 Japanese healthy controls were recruited. We genotyped 9 single-nucleotide polymorphisms in IL10 and assessed the allelic diversity(More)
