Patient-centered outcomes after subepithelial connective tissue grafts and coronally advanced flaps

The use of a coronally advanced flap (CAF) and connective tissue graft (CTG) is a well-established procedure to cover single and multiple recessions and improve soft tissue esthetics. However, until now, there are still limited data evaluating patient morbidity, the fear of imminent tooth loss, and modification of sensitivity in surgical areas. The aim of the present study was to evaluate the patient-centered outcomes associated with CAF + CTG.

Advanced reconstructive technologies for periodontal tissue repair

Reconstructive therapies to promote the regeneration of lost periodontal support have been investigated through both preclinical and clinical studies. Advanced regenerative technologies using new barrier-membrane techniques, cell-growth-stimulating proteins or gene-delivery applications have entered the clinical arena. Wound-healing approaches using growth factors to target the restoration of tooth-supporting bone, periodontal ligament and cementum are shown to significantly advance the field of periodontal-regenerative medicine. Topical delivery of growth factors, such as platelet-derived growth factor, fibroblast growth factor or bone morphogenetic proteins, to periodontal wounds has demonstrated promising results. Future directions in the delivery of growth factors or other signaling models involve the development of innovative scaffolding matrices, cell therapy and gene transfer, and these issues are discussed in this paper.

HMGA1 and HMGA2 protein expression correlates with advanced tumour grade and lymph node metastasis in pancreatic adenocarcinoma

Pancreatic ductal adenocarcinoma follows a multistep model of progression through precursor lesions called pancreatic intraepithelial neoplasia (PanIN). The high mobility group A1 (HMGA1) and high mobility group A2 (HMGA2) proteins are architectural transcription factors that have been implicated in the pathogenesis and progression of malignant tumours, including pancreatic cancer. The aim of this study was to explore the role of HMGA1 and HMGA2 in pancreatic carcinogenesis.
