1. Cellular mechanisms involved in bone resorption
Abstract : The effects of parathyroid hormone (PTH), prostaglandins (PGE1, PGE2, PGF2a), cAMP, cAMP-analogues, phosphodiesterase (PDE) inhibitors and la (OH) D3 on bone resorption and associated cellular process have been studied in a bone organ culture system using half- calvaria from 6-7 day-old mice. Bone resorption was assessed by determining the release of calcium (Ca2+), inorganic phosphate (Pi) and 45Ca from the calvarial bones to the culture media. READ MORE

2. Cellular and molecular responses of periodontal connective tissue cells to Actinobacillus actinomycetemcomitans cytolethal distending toxin
Abstract : Actinobacillus actinomycetemcomitans is present in elevated proportions and numbers in dental bacterial biofilms of patients with localized aggressive periodontitis. This variant of periodontal disease, occurring in adolescents and young adults, is characterized by rapid and severe destruction of the connective tissues and bone supporting the teeth, eventually culminating in tooth loss.

3. Kinins : important regulators in inflammation induced bone resorption
Abstract : Inflammatory processes in, or in close vicinity of, the skeleton often lead to loss of bone tissue. Different cytokines have been shown to be involved as stimulators of inflammatory induced osteoclastic bone resorption. READ MORE

4. The calcitonin gene family of peptides : receptor expression and effects on bone cells
Abstract : The calcitonin gene family of peptides consists of calcitonin (CT), two calcitonin gene related peptides (α-CGRP, β-CGRP), adrenomedullin (ADM), amylin (AMY), three calcitonin receptor activating peptides (CRSP1-3) and intermedin/adrenomedullin2 (IMD). These peptides bind to one of two G protein -coupled receptors, the calcitonin receptor (CTR) or the calcitonin receptor-like receptor (CRLR). READ MORE

5. Oral health and cardiovascular disease
Abstract : In the past two decades studies have indicated that oral health might be associated with the prevalence for cardiovascular disease (CVD), although the biological link still remains unknown. Bacteria and inflammatory mediators causing periodontal disease have also been suggested to influence the progression of atherosclerosis. READ MORE
