Title: Diagnosing death by drowning through the analysis of blood markers by inductively coupled plasma: mass spectrometry Abstract: Investigation of bodies recovered out of water is a complex but frequent medico-legal task. The key problem is if the victim died due to drowning or by the means of other cause and placed in water. At the moment, the diagnosis of drowning is based on some unspecific findings during autopsy (lung distension and the presence of froth in upper airways and lungs) and the results of laboratory tests. Our project aimed to evaluate the usefulness of the determination by ICP-MS of trace elements (TE) in blood of the cardiac cavities of corpses found in aquatic environment as a tool to increase the certainty of the diagnostic of death by drowning. Blood samples were collected from 18 cadavers found in water, from 2006-2008, in Oporto area. The advantage of ICP-MS compared to other instrumental analytical techniques is clear and it proved to be useful. It allowed us to perform a multielemental analysis of blood, and the results highlight the importance of this kind of approach, compared to previous studies where we are dependent on the results of a single TE.

Title: Development and characterization of lanthanides doped hydroxyapatite composites for bone tissue application Abstract: This work reports the preparation and characterization of newly developed 10CaF2-10Na2CO3-15CaO-59P205-5Si02 glasses, doped with lanthanides, in this case cerium and lanthanum oxide (10CaF2-10Na2CO3-15CaO-59P205-1CeO2-5SiO2 and 10CaF2-10Na2CO3-15CaO-59P205-1La2O3-5SiO2, respectively). The structure and morphology of the developed glasses have been investigated by Raman and FTIR spectroscopy. Scanning electron microscopy with an energy dispersive analyzer and X-ray mapping was used to assess the morphological properties of the glasses. Glass-ceramic composites, for bone tissue applications, were obtained by the mixture of 2.5wt% of each glass with 97.5wt% of hydroxyapatite. These were also analyzed by means of XRD and SEM. Composites were biologically evaluated with human osteoblastic-like cells. Lanthanide doped-hydroxyapatite composites revealed an improved biological behaviour, regarding cell adhesion and proliferation, compared to hydroxyapatite and undoped glasshydroxyapatite composites. Lanthanide doped composites reported an adequate biocompatibility, further enhancing the cell adhesion and proliferation, behaviour that indicates a prospective application in bone tissue engineering.

Title: Calcium phosphate ceramics in periodontal regeneration Abstract: Regenerative periodontal therapy aims to predictably restore the tooth'ssupporting periodontal tissues and should result in the formation of a new connectivetissue attachment (i.e. new cementum with inserting periodontal ligament fibres) andnew alveolar bone. This chapter aims to address the clinical application of bone graftson periodontal regenerative approaches, with given relevance to the use of calciumphosphate ceramics. Furthermore, a clinical case is presented in which the regenerativecapability of a glass-reinforced hydroxyapatite (Bonelike®) is thoroughly evaluated byclinical and tomographic measurements in the healing of a periodontal intrabony defect.
