BACKGROUND Regenerative periodontal therapy aims to predictably restore the tooth's supporting periodontal tissues and should result in formation of a new connective tissue attachment (i.e. new cementum with inserting periodontal ligament fibres) and new alveolar bone. Histologic evidence from preclinical models has demonstrated periodontal regeneration following treatment with barrier membrane...

OBJECTIVE Minimally invasive direct coronary artery bypass (MIDCAB) is performed under direct vision without sternotomy or cardiopulmonary bypass. The technique is used in reoperative patients through various incisions to revascularize one or two areas of the heart. The internal mammary artery, gastroepiploic artery, radial artery, or saphenous vein are used as graft conduits. METHODS Anterio...

Grafting is a centuries-old technique used in plants to obtain economic benefits. Grafting increases nutrient uptake and utilization efficiency in a number of plant species, including fruits, vegetables, and ornamentals. Selected rootstocks of the same species or close relatives are utilized in grafting. Rootstocks absorb more water and ions than self-rooted plants and transport these water and...

Control and tuning of surface properties is indispensable for the programmed and rational design of materials. Particularly, polymeric brush-modified colloids can be used as carrier materials for enzyme immobilization. Although it is of prime importance to control the brush architecture, there is still a lack of systematic investigations concerning the impact of grafting density on the properti...

Autologous fat grafting enables repair and augmentation of soft tissues and is increasingly used in plastic and reconstructive surgery. The main limitation of fat grafting is unpredictable graft resorption. To obviate this disadvantage, several studies have searched for new ways of increasing the viability of the transplanted tissue. One promising approach has been to mix the fat graft with Pla...

INTRODUCTION Alveolar bone grafting is a vital part of the rehabilitation of cleft patients. The factors that have been most frequently associated with the success of the graft are the age at grafting and the pre-grafting orthodontic treatment. OBJECTIVES 1) Describe the cases of alveolar bone grafts performed at the Maxilofacial Unit of Hospital Sant Joan de Déu, Barcelona (HSJD); and 2) Ana...

OBJECTIVE Percutaneous coronary intervention with drug-eluting stents is challenging coronary artery bypass grafting (CABG) as the gold standard for treatment of three-vessel and left main coronary disease. We evaluated the current practice pattern in hospitals throughout Europe and USA. METHODS To qualify for participation in the SYNTAX (Synergy between PCI with TAXUS drug-eluting stent and ...

Polymer chains are irreversibly grafted to a surface in a good solvent and the solvent quality is then reduced dramatically. The chains then collapse. If the grafting density is very high then the collapsed layer should be fairly uniform. However, at lower grafting densities the chains are predicted to form surface "micelles". These micelles minimize the exposed surface area of the collapsed gl...

The use of the rib for primary alveolar cleft bone grafting offers one of the few donor sites for grafting under one year of age. Its use in 211 patients in an 11 year period revealed no morbidity other than a small donor scar. Rib grafting in infants differs significantly from that in teenagers and adults with minimal pain, no risk of pneumothorax when properly performed, and more than an adeq...
