1. On surgical techniques to increase bone density and volume. Studies in the rat and the rabbit
Abstract : BACKGROUND. Various techniques of surgical intervention have been suggested to promote bone densityand volume; however, the predictability of such techniques is not always sufficiently supported by preclinicalevaluations.AIM. READ MORE

2. 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

3. Biogenesis of tartrate-resistant acid phosphatase isoforms 5a and 5b in cell and animal models
Abstract : Tartrate-resistant acid phosphatase (TRAP) is an iron-containing binuclear acid metallohydrolase that belongs to the purple acid phosphatase (PAP) family. It is a glycoprotein translated as a monomeric protein but is commonly isolated from tissues as a proteolytically processed dimeric form with increased enzyme activity. READ MORE

4. Tissue responses to bone-implant biomaterials
Abstract : The purpose of the studies was to understand the mechanisms which underlie the interaction between tissue and bone-implant biomaterials. Tissue and naturally occurring aragonite nacre interaction was systematically studied for the first time by combined histological examination, cellular and molecular biological approaches. READ MORE

5. 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
