Abstract
OBJECTIVES The longevity of homografts is determined by the activation of the recipients' immune system resulting from allogenic antigen exposition. Fresh decellularized pulmonary homografts (DPH) have shown promising early results in pulmonary valve replacement in children and young adults and could potentially avoid significant activation of the immune system, as more than 99% of the donor DNA is removed during the decellularization process. While the humoral immune response to decellularized allografts has been studied, detailed information on the more significant cellular immune response is currently lacking. METHODS AND RESULTS Peripheral blood samples were obtained from patients undergoing pulmonary valve replacement with DPH before, after, and for approximately 3 years after implantation. Absolute counts and percentages of mature T- (CD3(+)), B- (CD19(+)), and natural killer- (CD16(+)/CD56(+)) cells, as well as T helper- (CD4(+)) and cytotoxic T-cell- (CD8(+)) subsets, were determined by fluorescence-activated cell sorting (FACS). Between May 2009 and September 2013, 199 blood samples taken from 47 patients with a mean age at DPH implantation of 16.6±10.8 years were analyzed. The hemodynamic performance of DPH was excellent in all but one patient, and no valve-related deaths or conduit explantations were observed. The short-term follow up revealed a significant postoperative decrease in cell counts of most subtypes with reconstitution after 3 months. Continued assessment did not show any significant deviations in cell counts from their baseline values. CONCLUSION The absence of cellular immune response in patients receiving DPH supports the concept that decellularization can provide a basis for autologous regeneration.

Abstract
PURPOSE To evaluate a novel feedback-regulated volumetric sonication method in MRguided HIFU treatment of symptomatic uterine fibroids. MATERIALS AND METHODS 27 fibroids with an average volume of 124.9 ± 139.8 cc in 18 women with symptomatic uterine fibroids were ablated using the new HIFU system Sonalleve (1.5 TMR system Achieva, Philips). 21 myomas in 13 women were reevaluated 6 months later. Standard (treatment) cells (TC) and feedback-regulated (feedback) cells (FC) with a diameter of 4, 8, 12, and 16 mm were used and compared concerning sonication success, diameter of induced necrosis, and maximum achieved temperature. The non-perfused volume ratio (NPV related to myoma volume) was quantified. The fibroid volume was measured before, 1 month, and 6 months after therapy. Symptoms were quantified using a specific questionnaire (UFS-QoL). RESULTS In total, 205 TC and 227 FC were applied. The NPV ratio was 23 ± 15 % (2 – 55). The TC were slightly smaller than intended (-3.9 ± 52 %; range, -100 – 81), while the FC were 20.1 ± 25.3 % bigger (p = 0.02). Feedback mechanism is less diversifying in diameter (p < 0.001). Overall, the FC correlate well with the planned treatment diameter (r = 0.79), other than the TC (r = 0.38). Six months after therapy, the fibroid volume was reduced by 45 ± 21 % (5 – 100) (p = 0.001). The symptoms decreased significantly (p = 0.001). No serious adverse events were recorded. CONCLUSION Use of volumetric sonication leads to homogenous heating and sufficient necrosis. It is a safe and effective therapy for treating symptomatic uterine fibroids. Successful sonication of feedback cells leads to more contiguous necrosis in diameter

Abstract
INTRODUCTION Lung cancer is the most common cancer worldwide. Every year, as many people die of lung cancer as of breast, colon and rectum cancers combined. Because most patients are being diagnosed in advanced, not resectable stages and therefore have a poor prognosis, there is an urgent need for alternative therapies. Since it has been demonstrated that a high number of tumor- and stromal-infiltrating cytotoxic T cells (CTLs) is associated with an increased disease-specific survival in lung cancer patients, it can be assumed that immunotherapy, e.g. peptide vaccines that are able to induce a CTL response against the tumor, might be a promising approach. METHODS We analyzed surgically resected lung cancer tissues with respect to HLA class I- and II-presented peptides and gene expression profiles, aiming at the identification of (novel) tumor antigens. In addition, we tested the ability of HLA ligands derived from such antigens to generate a CTL response in healthy donors. RESULTS Among 170 HLA ligands characterized, we were able to identify several potential targets for specific CTL recognition and to generate CD8+ T cells which were specific for peptides derived from cyclin D1 or protein-kinase, DNA-activated, catalytic polypeptide and lysed tumor cells loaded with peptide. CONCLUSIONS This is the first molecular analysis of HLA class I and II ligands ex vivo from human lung cancer tissues which reveals known and novel tumor antigens able to elicit a CTL response.

Abstract
AIM To review the available literature on the durability of amalgam when used to restore interproximal (class II) cavities in primary molars. METHODS The literature was searched using OVID Medline and EMBASE from 1966 to 2006. The search plan of the electronic databases included: "dental amalgam or amalgam or alloy" and "deciduous or primary or milk or first or baby or natal" or "tooth or teeth or dentition" and "permanent restorations or permanent fillings". Relevant prospective clinical studies were reviewed by 2 reviewers against a set of defined criteria. Papers were graded according to the number of criteria met as A = >90%, B1 = 75%, B2 = 50% and C = <50%. RESULTS No study achieved a Grade A; four studies rated Grade B1 and thirteen B2. Seven studies were rated Grade C. A wide range of failure rates for amalgam were reported from 0 - 58%. However, in the context of a controlled clinical environment in a developed country the failure rate varied between 0 and 22%. CONCLUSION Amalgam remains an appropriate choice of material for the restoration of the primary dentition. However, factors other than durability are increasingly influencing its use in clinical practice.
