INTRODUCTION The role of fat-bone interactions in the pathogenesis of osteoporosis in chronic obstructive pulmonary disease (COPD) is poorly understood. Our aim was to investigate expressions of leptin and osteoprotegerin (OPG) in the adipose tissue, and their relationships to osteoporosis in patients with COPD. METHODS In 39 patients with stable COPD,(More)
BACKGROUND Osteoprotegerin (OPG), a potent inhibitor of osteoclastogenesis, decreases bone resorption and has protective effects on bone mineral density (BMD). Recently we have shown that the adipose-tissue derived OPG relates to BMD in patients with chronic obstructive pulmonary disease (COPD), a condition associated with increased risk of osteoporosis.

BACKGROUND CD40, a transmembrane receptor of the tumor necrosis factor gene superfamily, is activated in response to cellular stress, including hypoxia, and orchestrates the process of inflammation via secondary messengers such as mitogen-activated protein kinase kinase 4 (MKK4) and c-Jun NH(2)-terminal kinases (JNK). OBJECTIVES We hypothesized that CD40,(More)
Potential links between metabolic derangements and adipose tissue (AT) inflammation in patients with chronic obstructive pulmonary disease (COPD) are unexplored. We investigated AT expressions of interleukin (IL)-6, tumor necrosis factor (TNF)-α, CD68 (macrophage cell surface receptor), caspase-3, and Bax, and their relationships to the metabolic phenotype(More)
Recently we observed increased adipose tissue (AT) expression of CD40-related signaling proteins but no activation of tumor necrosis factor-α or CD68 in patients with chronic sustained hypoxia resulting from chronic obstructive pulmonary disease (COPD). Transcription factor nuclear factor-κB (NFκB) is involved in cellular responses to hypoxia and activates(More)
OBJECTIVE Chronic obstructive pulmonary disease (COPD) is associated with increased cardiovascular morbidity and mortality. Several large population-based cohort studies identified an association between reduced lung function and increased intima-media thickness (IMT). Nevertheless, a vast majority of subjects in these studies did not suffer from COPD and(More)
INTRODUCTION Results of previous studies comparing bypass surgery and percutaneous transluminal angioplasty in peripheral artery disease are ambiguous. Therefore, the aim of our study was to analyse and compare the long-term results of surgical and endovascular revascularisation in patients with peripheral artery disease in the femoropopliteal region.

Malignant fibrous histiocytoma (MFH) represents a rare malignant affection of heart and aorta. Its clinical presentation depends on the localisation, size, degree of invasion and metastasis. Previously, relatively few cases of acute tumour mass embolisation into the visceral and limb arterial system were described in the literature. In the present case(More)
Obstructive sleep apnoea (OSA) has been associated with disturbances in energy metabolism and insulin resistance, nevertheless, the links between OSA severity, resting energy expenditure (REE) and insulin resistance (homeostasis model assessment, HOMA-IR) remained unexplored. Therefore, we investigated the effects of OSA severity on REE, and relationships(More)
