Characteristics and clinical relevance of late gadolinium enhancement in cardiac magnetic resonance in patients with systemic sclerosis

Cardiac involvement in systemic sclerosis (SSc) is considerably frequent in autopsy, but the early identification is clinically difficult. Recent advantages in cardiac magnetic resonance (CMR) enabled to detect myocardial fibrotic scar as late gadolinium enhancement (LGE). We aimed to examine the prevalence and distribution of LGE in patients with SSc, and associate them with...

CD40-CD40 ligand signal induces the intercellular adhesion molecule-1 expression through nuclear factor-kappa B p50 in cultured salivary gland epithelial cells from patients with Sjögren's syndrome

The purpose of this study is to clarify signal transduction of expression of the intercellular adhesion molecule-1 (ICAM-1) via CD40-CD40 ligand in salivary glands of patients with Sjögren's syndrome (SS). We used cultured salivary gland epithelial cells (SG cells) from 15 SS patients and 8 controls obtained by labial minor salivary gland biopsy. First, ICAM-1 expression was...

Oxygen free radicals and calcium homeostasis in the heart

Many experiments have been done to clarify the effects of oxygen free radicals on Ca2+ homeostasis in the hearts. A burst of oxygen free radicals occurs immediately after reperfusion, but we have to be reminded that the exact levels of oxygen free radicals in the hearts are yet unknown in both physiological and pathophysiological conditions. Therefore, we should give careful...
