Abstract
AIM To reach a consensus on a consistent strategy to adopt when screening patients for dental/periodontal infections and on the feasibility of providing dental treatment before cardiothoracic surgery, cardiovascular surgery or other cardiovascular invasive procedures. METHODOLOGY A panel of experts from six Italian scientific societies was created. The deliberations of the panel were based on the RAND method. From an initial systematic literature review, it became clear that a consensually validated protocol for the reproducible dental screening of patients awaiting cardiac interventions was considered mandatory by professionals with expertise in the dental, cardiologic and cardiac surgery areas. However, a systematic review also concluded that the treatment options to be provided, their prognosis and timing in relation to the physical condition of patients, had never been defined. Following the systematic review, several fundamental questions were generated. The panel was divided into two working groups each of which produced documents that addressed the topic and which were subsequently used to generate a questionnaire. Each member of the panel completed the questionnaire independently, and then, a panel discussion was held to reach a consensus on how best to manage patients with dental/periodontal infections who were awaiting invasive cardiac procedures. RESULTS A high level of agreement was reached regarding all the items on the questionnaire, and each of the clinical questions formulated were answered. Three tables were created which can be used to generate a useful tool to provide standardized dental/periodontal screening of patients undergoing elective cardiovascular interventions and to summarize both the possible oral and cardiovascular conditions of the patient and the timing available for the procedures considered. CONCLUSIONS Upon publication of this consensus document, the dissemination of the information to a wide dental and cardiac audience should commence. The authors hope that this consensus will become a model for the development of a dedicated protocol, ideally usable by heart and dental teams in the pre-interventional preparation phase.

Abstract
SummaryIt is already known that activation of the coagulation and fibrinolytic system occurs in patients undergoing cardiopulmonary bypass (CPB). We have thus studied twenty patients (10 treated with aprotinin during CPB and 10 untreated) both during the intraoperative period and during thirty days follow up. In untreated patients D-dimer levels increased 4-fold during CPB and the levels were above baseline for the whole follow up (p<0.0001). D-dimer levels were reduced in aprotinin treated patients in comparison to untreated patients (p = 0.0172); levels then gradually increased to the values of the untreated patients over the following 24 h later and remained higher during the thirty day follow up. The behavior of haemostatic variables in the 24 h after CPB did not vary between untreated and aprotinin treated patients. In particular, five minutes after protamine sulphate administration, levels of F1 + 2 and TAT rose significantly (p = 0.0054, p = 0.0022 respectively), whereas fibrinogen significantly decreased (p<0.0001) and PAI-1 antigen levels were reduced. Two days after CPB the concentrations of F1 + 2 and TAT lowered, whereas fibrinogen and PAI-1 antigen levels increased. On the 5th, 8th and 30th days after CPB, F1 + 2 and TAT levels remained higher than those reported at baseline in both groups of patients, whereas fibrinogen levels increased over basal levels in aprotinin treated patients only.Thus, in addition to the activation of the coagulation and fibrinolytic system occurring during the intraoperative period, in patients undergoing CPB, there are alterations of haemostatic variables up to thirty days from surgery.

Abstract
In a previous paper, the biological activity of a 216-amino acid recombinant truncated form of the soybean 7S globulin α' subunit, known to control cholesterol and triglyceride homeostasis, was described. In this work, a shorter version of the polypeptide chain, spanning 142 amino acid residues from the N-terminus and thus exclusively including the so-called extension region, was cloned and overexpressed in Pichia pastoris. The yield of the recombinant polypeptide, which was termed α'E, was 8-fold greater than the previous truncated version. The α'E polypeptide was purified by simple conventional biochemical techniques to make it available for biological assays. Human hepatoma cell lines (Hep G2) were used to monitor the uptake and degradation of labeled low-density lipoproteins (LDL), according to an established procedure. The LDL uptake (+86%) and degradation (+94%) by cells tested at the highest α'E dose (2 μM) were similar to those found in cells incubated with 1 μM simvastatin, a potent inhibitor of cholesterol biosynthesis. Additionally, the cell response to α'E was found to be dose-dependent. The present findings strongly suggest that this recombinant polypeptide, or a fragment thereof, is the molecular determinant for cholesterol homeostasis and open new prospects for understanding the mechanism involved in this biological response, as a gateway to its utilization in lipid-lowering therapies.

Abstract
BACKGROUND Protease-activated receptors (PARs) comprise a family of G-protein-coupled receptors with a unique mechanism of proteolytic activation. PARs regulate a broad range of cellular functions and are active in the pathogenesis of disorders characterized by chronic inflammation or activation of the coagulation cascade. Signaling through PAR1 and PAR2 shifts the endothelium towards a prothrombotic phenotype, thereby exacerbating the initial pathophysiologic condition. OBJECTIVES This study aimed to analyze the localization of PARs in the cell membrane and how their compartmentalization affects tissue factor (TF) in human endothelial cells. METHODS TF expression was determined by quantitative real-time polymerase chain reaction analysis and by activity assays. The interaction of PARs with caveolin was investigated through: (i) caveolin-1 gene knockdown performed by transfection with specific small interfering RNA (siRNA); (ii) caveolin-enriched membrane microdomain disruption; and (iii) coimmunoprecipitation assay. RESULTS We have shown that PAR1, but not PAR2, is present in endothelial caveolin-enriched membrane microdomains, where it is bound to caveolin-1, and that these structures must be intact if PAR1-induced signaling is to increase TF activity. Cholesterol depletion of endothelial cells by cholesterol-sequestering agents caused the PAR1 to relocate to high-density membranes, and impaired the induction of TF (P < 0.01) without affecting the PAR2-mediated procoagulant effect. In addition, siRNA directed against caveolin-1 inhibited TF activation by PAR1 (P < 0.01 and P < 0.01, respectively). CONCLUSIONS PAR1 localization in the caveolin-enriched membrane microdomain, bound to caveolin-1, represents a crucial requirement for TF induction in endothelial cells.

Abstract
BACKGROUND Patency rates after coronary artery bypass grafting (CABG) are better if the internal mammary artery (IMA) is used rather than the greater saphenous vein (GSV), and may be related to the endothelial release of vasodilators antagonizing vascular contraction. It has recently been shown that a family of protease-activated receptors (PARs) modulate endothelium-dependent vasodilatation. OBJECTIVE AND METHODS The aim of this study was to evaluate the presence and functional role of protease-activated receptor 1 (PAR1) and protease-activated receptor 2 (PAR2) in mediating vascular tone in IMAs and GSVs from patients undergoing CABG by means of real time-PCR and isometric tension measurements. RESULTS PAR1 mRNA levels were higher than those of PAR2 mRNA in both vessels. A selective PAR2-activating peptide (PAR2-AP), SLIGKV-NH(2) (0.01-100 micromol L(-1)), failed to induce vasorelaxation in precontracted IMA and GSV rings, whereas the selective PAR1-AP, TFLLR-NH(2) (0.001 to 10 micromol L(-1)), caused greater endothelium-dependent relaxation in the IMAs (pD(2) values 7.25 +/- 0.6 vs. 7.86 +/- 0.42, P < 0.05; E(max) values 56.2 +/- 17.3% vs. 29.7 +/- 13.4%, P < 0.001). Preincubation with TNFalpha (3 nmol L(-1)) induced vasorelaxation in IMAs in response to PAR2-AP (P < 0.05 vs. non-stimulated vessels); the response to PAR1-AP was unchanged. The relaxation induced by both PAR-APs was NO- and endothelium-dependent. CONCLUSION These data show that functionally active PAR1 and PAR2 are present in IMAs and GSVs, and that inflammatory stimuli selectively enhance endothelium-dependent relaxation to PAR2-AP in IMAs.
