AbstractInterleukin-6 (IL6) has come to be regarded as a potential osteoporotic factor because it has stimulatory effects on cells of the osteoclast lineage, and, thus, may play a role in the pathogenesis of bone loss associated with estrogen deficiency. We previously described association of the IL6 microsatellite with bone mineral density (BMD), as well(More)
AbstractInterleukin 11 (IL11) is a member of the interleukin 6 (IL6)-related cytokine subfamily, which stimulates T cell-dependent development of immunoglobulin-producing B cells. IL11 is also an important paracrine regulator of bone metabolism that induces formation of osteoclasts. In the work reported here, we sequenced the entire IL11 structural gene of(More)
BACKGROUND Clinical data suggest that changes in intrathoracic impedance and fluid accumulation in the lung are inversely related. METHODS AND RESULTS Daily shock impedance (S-IMP) was evaluated in 29 patients in whom a Ventak Prizm 2 was implanted (61+/-14 years old). The mean follow-up period was 45+/-18 weeks, during which 6 patients had episodes of(More)
We investigated whether polymorphism of the type 6 adenylyl cyclase gene influences the occurrence of left ventricular hypertrophy in a Japanese population. Type 6 adenylyl cyclase is a major cardiac adenylyl cyclase isoform and plays an important role in regulating cardiac function. We examined the type 6 adenylyl cyclase gene for single nucleotide(More)
BACKGROUND Tumour necrosis factor-alpha (TNFalpha) is an essential regulator of immune responses and is implicated to relate to several types of disease susceptibilities. Population information on polymorphisms is essential for the study of genetic diseases. AIM To obtain accurate information about single nucleotide polymorphisms (SNPs) in the TNFalpha(More)
BACKGROUND Biatrial pacing has a significant problem with memory function that misinterprets normal sinus rhythm as atrial tachyarrhythmias and in addition estimation of the atrial pacing thresholds (biatrial and uniatrial pacing thresholds) is sometimes difficult because of small P waves. METHODS AND RESULTS The intracardiac electrograms recorded by a(More)
