Abstract
PURPOSE No single reliable biomarker is available for nonfunctioning pancreatic neuroendocrine tumors (NF-PanNETs). Vasostatin-1 (VS-1), the N-terminal fragment of chromogranin A (CgA), seems to be a more accurate biomarker compared to its precursor. Primary aim was to investigate the ability of VS-1, compared to total-CgA, to assess the effectiveness of surgical resection performed for NF-PanNETs. Secondary aim was to evaluate two additional CgA-derived fragments, pancreastatin (PST) and vasostatin-2 (VS-2), as possible biomarkers for NF-PanNETs. METHODS Consecutive patients who underwent surgery for NF-PanNETs at San Raffaele Scientific Institute were included (n = 35). Plasma levels of CgA and CgA-derived fragments were measured by Enzyme-Linked ImmunoSorbent Assay (ELISA), preoperatively and postoperatively. RESULTS Preoperative VS-1 was significantly higher compared to VS-1 measured on postoperative day 5 (POD5) (pre: 0.338 nM versus POD5: 0.147 nM, P < 0.001), whereas total-CgA significantly increased after surgery (pre: 1.123 nM versus POD5: 1.949 nM, P = 0.006). Overall, 24 patients showed ≥ 1 feature of tumor aggressiveness (T3-T4, nodal/distant metastases, Ki67 > 5%, microvascular/perineural invasion, necrosis). The median percentage decrease in VS-1 plasma levels was 63% (IQR 28-88%) among patients with aggressive tumors, compared to 13% (IQR 0-57%) in the remaining population (P = 0.033). No significant differences in terms of PST (P = 0.870) and VS-2 (P = 0.909) were observed between preoperative and postoperative time. CONCLUSION VS-1 provides an early assessment of surgical efficacy in patients who undergo resection for NF-PanNETs, especially in those with aggressive neoplasms. Total-CgA, PST and VS-2 have no clinical utility in this setting.

Abstract
The generation of physiologically relevant in-vitro models of biological barriers can play a key role in understanding human diseases and in the development of more predictive methods for assessing toxicity and drug or nutrient absorption. Here, we present an advanced cell culture system able to mimic the dynamic environment of biological barriers while monitoring cell behaviour through real-time impedance measurements and imaging. It consists of a fluidic device with an apical and a basal flow compartment separated by a semi-permeable membrane. The main features of the device are the integration of sensing through transepithelial electrical impedance (TEEI) measurements and transparent windows for optical monitoring within a dual flow system. Caco-2 cells were cultured in the TEEI bioreactor under both flow and static conditions. Although no differences in the expression of peripheral actin and occludin were visible, the cells in dynamic conditions developed higher impedance values at low frequencies, indicative of a higher paracellular electrical impedance with respect to the static cultures. TEEI measurements at high frequency also enabled monitoring monolayer formation, which can be correlated with the observation of an RC behaviour in the impedance spectra. In particular, the cells subject to flow showed accelerated barrier formation and increased vitality with respect to the static controls, again highlighting the importance of dynamic conditions for epithelial cells.

Abstract
The residual urban waste of Prato district (Italy) is characterized by a high calorific value that would make it suitable for direct combustion in waste-to-energy plants. Since the area of central Italy lacks this kind of plant, residual municipal waste is quite often allocated to mechanical treatment plants in order to recover recyclable materials (such as metals) and energy content, sending the dry fractions to waste-to-energy plants outside the region. With the previous Italian legislation concerning Refuse Derived Fuels, only the dry stream produced as output by the study case plant, considered in this study, could be allocated to energy recovery, while the other output flows were landfilled. The most recent Italian regulation, introduced a new classification for the fuel streams recovered from waste following the criteria of the European standard (EN 15359:2011), defining the Solid Recovered Fuel (SRF). In this framework, the aim of this study was to check whether the different streams produced as output by the study case plant could be classified as SRF. For this reason, a sampling and analysis campaign was carried out with the purpose of characterizing every single output stream that can be obtained from the study case mechanical treatment plant, when operating it in different ways. The results showed that all the output flows from the study case mechanical treatment plant were classified as SRF, although with a wide quality range. In particular, few streams, of rather poor quality, could be fed to waste-to-energy plants, compatibly with the plant feeding systems. Other streams, with very high quality, were suitable for non-dedicated facilities, such as cement plants or power plants, as a substitute for coal. The implementation of the new legislation has hence the potential for a significant reduction of landfilling, contributing to lowering the overall environmental impact by avoiding the direct impacts of landfilling and by exploiting the beneficial effects of energy recovery from waste.

Abstract
Serpinin peptides derive from proteolytic cleavage of Chromogranin-A at C-terminus. Serpinin and the more potent pyroglutaminated-serpinin (pGlu-Serp) are positive cardiac β-adrenergic-like modulators, acting through β1-AR/AC/cAMP/PKA pathway. Because in some conditions this pathway and/or other pro-survival pathways, activated by other Chromogranin-A fragments, may cross-talk and may be protective, here we explored whether pGlu-Serp cardioprotects against ischemia/reperfusion injury under normotensive and hypertensive conditions. In the latter condition, cardioprotection is often blunted because of the limitations on pro-survival Reperfusion Injury Salvage Kinases (RISK) pathway activation. The effects of pGlu-Serp were evaluated on infarct size (IS) and cardiac function by using the isolated and Langendorff perfused heart of normotensive (Wistar Kyoto, WKY) and spontaneously hypertensive (SHR) rats exposed to ischemic pre-conditioning (PreC) and post-conditioning (PostC). In both WKY and SHR rat, pGlu-Serp induced mild cardioprotection in both PreC and PostC. pGlu-Serp administered at the reperfusion (Serp-PostC) significantly reduced IS, being more protective in SHR than in WKY. Conversely, left ventricular developed pressure (LVDevP) post-ischemic recovery was greater in WKY than in SHR. pGlu-Serp-PostC reduced contracture in both strains. Co-infusion with specific RISK inhibitors (PI3K/Akt, MitoKATP channels and PKC) blocked the pGlu-Serp-PostC protective effects. To show direct effect on cardiomyocytes, we pre-treated H9c2 cells with pGlu-Serp, which were thus protected against hypoxia/reoxygenation. These results suggest pGlu-Serp as a potential modulatory agent implicated in the protective processes that can limit infarct size and overcome the hypertension-induced failure of PostC.

Abstract
Changes in the level of ornithine decarboxylase mRNA after partial mesodiencephalic hemitransection were evaluated in various regions of the rat brain by means of in situ hybridization histochemistry coupled with computer-assisted image analysis. On days 1 and 2 after the lesion, increased accumulation of ornithine decarboxylase mRNA was observed on the lesioned side in various telencephalic regions (e.g. neostriatum and frontoparietal cortex), and in the pars compacta of the substantia nigra. Both in the frontoparietal cortex and substantia nigra a decreasing gradient of ornithine decarboxylase mRNA activation was observed going far from the site of the lesion. Seven days after the operation, ornithine decarboxylase mRNA levels returned to control values on the lesioned side but increased in some regions, such as the frontoparietal cortex, on the intact side. The present results demonstrate that the parent cell body biosynthetic machinery is activated by the mechanical lesion of the axons at the level of ornithine decarboxylase gene expression. The increase of ornithine decarboxylase mRNA is not as large as the enhancement in ornithine decarboxylase activity previously shown, suggesting that the response to the lesion may also involve changes in the rate of translation of ornithine decarboxylase mRNA and/or in the rate of degradation of ornithine decarboxylase protein.

Abstract
The aim of this study was to investigate hemocompatibility and cytotoxicity properties of synthetic polymer coatings containing various unsaturated carbonic acids with vinylacetate. Co-polymers of vinylacetate and crotonic acid (CA), maleic acid (MA), and itaconic acid (IA) were made. The materials were characterized in terms of their adhesion to metal supports (titanium and stainless steel) as well as hemocompatibility (% hemolysis, wettability, erythrocyte aggregation, hemoglobin content, thrombocyte count and lipid peroxidation levels) and cytotoxicity (human endothelial cell activity in vitro and chromosome aberrations, bone marrow proliferation and cell ploidy in rats). Co-polymers of unsaturated carbonic acids with vinylacetate exhibited good hemocompatibility properties, as opposed to vinylacetate homopolymer for which substantial levels of hemolysis were observed. By coating the metal supports with co-polymers the cytotoxic effects associated with the bare metal samples were markedly reduced. MA samples showed excellent hemocompatibility and no cytotoxicity, yet they lacked good adhesion properties to metal substrate, probably due to high water content. CA samples, having the highest density of carboxylic groups among the samples under investigation, showed increased bone marrow proliferation activity and cell ploidy in rats, as compared to controls. The most promising results in the present study were obtained for the samples with IA, which showed good adhesion to metal substrates, good hemocompatibility and low cytotoxicity. Thus, co-polymers of vinylacetate and IA rich in carboxylic groups are promising materials for the design of novel drug-eluting stents.

Abstract
Chromogranin A (CgA) belongs to the granin family of uniquely acidic secretory proteins co-stored and co-secreted with other hormones and peptides in elements of the diffuse neuroendocrine system. The granins arise from different genes and are characterized by numerous sites for post-translational cleavage into shorter peptides with postulated regulatory properties. This review is directed towards endocrine aspects of CgA and its biologically active peptides. There is ample evidence from in vitro studies of distinct effects and targets for three CgA-derived peptides, vasostatin-I, pancreastatin and catestatin. Endocrine regulations are indicated from in vivo studies, consistent with the postulated prohormone function of CgA for peptides with regulatory properties. Most of the effects fit into patterns of direct or indirect, inhibitory modulations of major functions, implicating CgA peptides in regulation of calcium and glucose metabolism, cardiovascular functions, gastrointestinal motility and nociception, tissue repair, inflammatory responses and as host defense peptides in the first phase of microbial invasions.

Abstract
3540 Background: NGRhTNF is a vascular targeting agent (VTA) exploiting a tumour homing peptide (CNGRCG) selectively binding angiogenic vessels in solid tumours where NGRhTNF specific binding relies on dynamic interactions with TNF-receptors and aminopeptidase N (CD13). NGRhTNF combines activity on tumour vascular permeability and direct anticancer activity. Consistently, mouse preclinical data indicate significant synergy between low dose NGRhTNF and cytotoxic agents. Methods: 4 dose levels of NGRhTNF (0.2 up to 1.6 mcg/sqm) have been administered q 3 w in 16 patients. Main end-points included safety, anticancer activity and pharmacokinetic.Measurement of circulating tumor and endothelial cells (CTC and CEC), sTNFRI and s TNFRII, along with plasma cyto-chemokine profile have been performed. Results: 16 patients were enrolled (6F/10M);median age 60,range 43–73). Toxicity was limited to constitutional symptoms, and chills were the most frequent event (40%). Over a median follow-up of 15 weeks, stable disease was achieved in 44% of patients, with long lasting disease control in 2 cases (27 and 75 weeks, with establishment of indication to radical surgery after 75 weeks, presently tumor free after removal of the residual tumor mass). In these 2 patients, VEGF, MMP-9, CA125, significantly decreased over time. DCE-MRI indicates that NGRhTNF increases vascular permeability after first drug exposure, particularly at the dose of 0.4 mcg/sqm, while following multiple infusions it exerts an antivascular effect, as demonstrated by the decrease of Ktrans values. Moreover NGRhTNF is able to elicit inflammatory and immune responses over time, as indicated by the modulation of expression of multiple cyto-chemokines. Finally, changes in CTC levels over time consistently matched the clinical outcome. Conclusions: Low dose NGRhTNF has an optimal safety profile along with anticancer activity acting on tumour vasculature and inducing relevant biological effects, thus rendering the agent suitable for a development both as monotherapy and in combination with chemotherapeutics. The phase II program is due to start in early 2007. [Table: see text]

Abstract
Kidney transplantation is now recognized as the treatment of choice for patients with chronic renal failure. Despite the extension of indications to patients suffering severe hypertension, ischemic heart disease, and chronic heart failure, the worldwide results are superb. However, perioperative cardiac complications occur in 6% to 10% of transplanted patients. Aggressive intraoperative volume expansion is still recommended to maximize graft functional recovery (up to 30 mL/kg/h, central venous pressure [CVP] > 15 mm Hg), but patients with preexistent cardiac disease or poor myocardial function are exposed to the risk of fluid overload, acute respiratory failure, and prolonged ventilation. Among the last 90 cases performed at our institution, good functional recovery of the graft was present in 94% of the patients within 2 weeks, despite a much more conservative intraoperative hydration policy (crystalloids 2400 +/- 1000 mL, 15 mL/kg/h, CVP 7-9 mm Hg). Graft failure which occurred in 5 patients was significantly correlated only with donor age, while perioperative cardiovascular complications had been present in 9 cases (10%) who were coronary artery disease patients (55%). Age above 50 years was the only significant risk factor. Supranormal volume loading is probably not always warranted in kidney transplantation.

Abstract
13052 Background: NGRhTNF is a vascular targeting agent (VTA) exploiting a tumour homing peptide (CNGRCG) selectively binding solid tumor (lung, renal, and colorectal) neovasculature. NGRhTNF specific binding relies on dynamic interactions with TNF-receptors, aminopeptidase N (CD13) and a specific integrin: a combination of receptors expressed by the tumor neovasculature endothelium, but not on normal vessels. This combination provides NGRhTNF with unique biological properties: at low dose, increased tumor vascular permeability, and massive tumor necrosis at high dose. Mouse preclinical data confirmed these properties, revealing also strong synergy between low dose NGRhTNF and cytotoxic agents (antracyclines, platinum based compounds, etc.). Methods: Based on these data, a series of studies were designed. A multicentre phase I study with NGRhTNF as single agent -still in progress- aims at defining MTD and preliminary anticancer activity, within the EORTC network (EORTC 16041). A single center phase I study exploiting the low dose range (0.2–1.6 μg/m2) aims at defining safety and NGRhTNF activity on the tumor vascular permeability using DCE MRI (HSR NGR002). Results: Twelve advanced neoplastic patients were enrolled in the HSR NGR002 study. Up to the dose of 1.6 μg/m2, the only common toxicity was represented by constitutional symptoms such as infusion-associated chills (40%) of mild to moderate intensity. At the tested doses, NGRhTNF increased vascular permeability, as shown by changes in DCE MRI parameters (Ktrans and Kep), and modulated the expression of chemokines possessing antiangiogenic activity. NGRhTNF achieved stable disease in about 45% of highly refractory treated patients, and still ongoing long lasting disease control in 2 cases (7 and 9 months along with sharp decline of CA125 and VEGF). Conclusions: NGR-hTNF, a VTA with a unique mechanism of action, combines activity on tumor vascular permeability and direct anti-cancer effect. Preliminary data in humans confirm its favourable safety profile along with remarkable anticancer activity, thus rendering the agent suitable for a development program alone or in combination with chemotherapeutics. Phase II low dose combination studies will begin in 2006. [Table: see text]

Abstract
TNF-alpha may improve drug delivery to tumors by alteration of vascular permeability. However, toxicity precludes its systemic administration in patients. NGR-TNF comprises TNF coupled to the peptide CNGRC, which is a ligand for CD13. CD13 is expressed on tumor vasculature. Therefore, to assess the efficacy of NGR-TNF its biological effect on tumor vasculature should be measured rather than its effect on tumor growth. The aim of this study was to assess the effects of a low dose of NGR-TNF (5 ng/kg) on vascular permeability, tumor hypoxia, perfusion and proliferation in lymphoma bearing mice. MRI measurements with blood pool contrast agent showed an increased leakage of the contrast agent from the vasculature in NGR-TNF treated tumors compared with controls (p < 0.05), suggesting NGR-TNF-induced vascular permeability. Immunohistochemical analysis two hours after NGR-TNF treatment showed a decrease in tumor hypoxia (p < 0.1) and an increase in labeling index of the S-phase marker bromodeoxyuridine (p < 0.1), possibly due to an increase in tumor blood flow after NGR-TNF treatment. Although a decrease in tumor hypoxia and an increase in labeling index could have lead to increased tumor growth, in this experiment after one day a decrease in tumor volume was measured. Possibly, the effects on tumor hypoxia and proliferation two hours after treatment are transient and overruled by other, more longlasting effects. For example, the observed increase in vascular permeability may lead to haemoconcentration and increased interstitial pressure, ultimately resulting in an reduction of tumor blood flow and thus a decrease in tumor growth. A beneficial effect of NGR-TNF in combination with other therapeutical agents may therefore critically depend on the sequence and timing of the regimens. Currently, NGR-TNF is being tested in clinical studies.

Abstract
An in vitro isolated working frog heart (Rana esculenta) was used to study the effects of exogenous CGA(1-76) (vasostatin 1), CGA(1-113) (vasostatin 2), and the synthetic CGA(7-57) on cardiac performance. Under basal cardiac conditions, the dose-response curves of the three peptides from 10(-8) to 10(-7) M showed a significant calcium-dependent negative inotropism that involved neither the endocardial endothelium nor the adrenergic and muscarinic receptors. In addition, the CgA fragments clearly counteracted the typical positive inotropism of isoprenaline (10(-<9) M). Taken together, these results provide the first evidence for a cardio-suppressive role for the vasostatins.

Abstract
We have found that chromogranin A (CgA), a protein released in circulation by neuroendocrine cells and neurons, prevents the vascular leakage induced by tumor necrosis factor (TNF) in a mouse model. Studies of the mechanism of action showed that CgA and its NH(2)-terminal fragments inhibit TNF-induced vascular permeability by preventing endothelial cytoskeleton rearrangements. We propose that neuronal/endocrine secretion of CgA could contribute to the regulation of endothelial barrier function and the protection of vessels against plasma leakage in inflammatory diseases.

Abstract
BACKGROUND In chronic heart failure, several hormonal systems are activated with diagnostic and prognostic implications. We tested the hypotheses that serum Chromogranin-A (CgA) -- a 49 kDa acid protein present in the secretor granules of neuroendocrine cells -- is increased in chronic heart failure and that CgA levels are a predictive factor for mortality. METHOD AND RESULTS In 160 patients with chronic heart failure, we measured serum CgA and other neuroendocrine hormones. The results showed that CgA is increased in chronic heart failure and the increase is related to the clinical severity of the syndrome: CgA levels in New York Heart Failure (NYHA) class II (median 146.9 ng x ml(-1), inter-quartiles 108.3-265.5) were significantly higher (P<0.05) than in class I (median 109.7 ng x ml(-1), inter-quartiles 96.7-137.6), and significantly lower (P<0.05) than in class III (median 279.0 ng x ml(-1), inter-quartiles 203.6-516.1). Class IV patients showed the highest serum levels of CgA (median 545.0 ng. ml(-1), inter-quartiles 231.8-1068.3), being statistically significantly different from class III patients (P<0.001). The association between survival and some recognized variables of prognostic significance, including CgA was also studied. The results showed that ejection fraction, noradrenaline, atrial natriuretic peptide, NYHA class and CgA were significant univariate prognosticators; however, in the multivariate analysis by the Cox proportional-hazard model, CgA and NYHA class were the only independent predictive factors for mortality (P<0.005, RR=1.22, 95% CI=1.06-1.41 and P=0.04, RR=1.58, 95% CI=1.02-2.46, respectively). CONCLUSIONS CgA is a pro-hormone, precursor of several active fragments likely to exert biological effects in chronic heart failure. CgA serum levels are increased in patients with chronic heart failure and are a predictive factor for mortality.

Abstract
Tumor pretargeting with biotinylated antibody/avidin complexes improves the therapeutic index of systemically administered biotin-tumor necrosis factor (TNF) conjugates. Since the number of biotins in this conjugate is known to be critical for activity, we have characterized the structure of different biotin-TNF conjugates, prepared by reaction with d-biotinyl-6-aminocaproic acid N-hydroxysuccinimide ester and identified the biotinylation sites by trypsin digestion, reverse-phase chromatography, and electrospray mass spectrometry analyses. The results have shown that N-terminal valine is a preferential biotinylation site at pH 5.8, half of biotins being located on the alpha-amino group of this residue in a conjugate bearing one biotin/trimer (on average). Moreover, evidence has been obtained to suggest that the remaining part of biotins are linked to the epsilon-amino group of lysine 128, 112, and 65, while lysine 11, 90, and 98 were practically unmodified. No evidence of O-biotinylation of serine, threonine and tyrosine was obtained.

Abstract
We have investigated the role of p55 and p75 tumor necrosis factor receptors 1 and 2 (TNFR1 and TNFR2, respectively) in TNF-induced alteration of endothelial permeability in vitro and in vivo. Stimulation of TNFR1 with an agonist antibody or a receptor-selective TNF mutein increased the flux of (125)I-albumin through endothelial cell monolayers. An antagonist anti-TNFR1 antibody, but not antagonist anti-TNFR2 antibodies, blocked the activity of TNF in vitro. Stimulation of TNFR1, but not TNFR2, induced cytoskeletal reorganization associated with increased permeability. SB-203580, a p38 mitogen-activated protein kinase inhibitor, blocked TNFR1-induced cytoskeletal reorganization and permeability. A selective mouse TNFR1 agonist and human TNF, which binds to murine TNFR1, increased the leakage of trypan blue-albumin from liver vessels in mice. These results indicate that stimulation of TNFR1 is necessary and sufficient to increase endothelial permeability in vitro and in vivo. However, an antagonist anti-murine TNFR2 antibody partially inhibited the effect of murine TNF on liver vessels, suggesting that TNFR2 also plays a role in the regulation of TNF-induced vascular permeability in vivo.

Abstract
Polyamines, spermidine (SPD), and spermine (SPM) are intracellular polycations required for cell growth and differentiation. Their biosynthetic precursor, the diamine putrescine (PUT), is produced by regulatory ornithine decarboxylase (ODC). Spermidine/spermine N1-acetyltransferase (SSAT) is the ODC counterpart in the degradation pathway which retroconverts SPM and SPD into PUT. Castration of male mice for 7 days resulted in a 40% decrease of the renal levels of both SSAT and ODC transcripts. Administration of 5-alpha-dihydrotestosterone (DHT) to castrated mice for the last 3 days before sacrifice caused the levels of ODC and SSAT mRNAs to increase by 250% and 180%, respectively. Thus activation of the retroconversion pathway of polyamine metabolism appears to contribute towards the increase in PUT production known to be caused by androgens in the mouse kidney. In situ hybridization histochemistry experiments showed that the SSAT transcript is expressed only by the epithelial cells of the straight and convoluted distal tubules of the nephron, while the expression of the ODC transcript is confined to the epithelium of the convoluted and straight portion of the proximal tubules. The separation of the biosynthetic from the degradation pathway along the nephron suggests that PUT is mostly produced in the distal tubule, where it may play a physiological role, independent of androgen action, in protecting tubular cells from the very low osmolarity to which they are exposed in this nephron segment.

Abstract
Surface-bound IgE play a central role in antiparasite immunity; to exploit IgE-driven immune mechanisms in tumor prevention and control, monoclonal IgEs of irrelevant specificity were loaded through biotin-avidin bridging onto tumor cells, either by systemic administration to tumor-bearing mice or pre-loading of tumor cells before inoculation. Here we show that systemic administration of biotinylated IgEs to mice bearing tumors pre-targeted with biotinylated antibodies and avidin significantly decreased tumor growth rate. In addition, as compared with IgG-loaded control cells, inoculation of suboptimal doses of IgE-loaded tumor cells suppressed tumor formation in a fraction of animals and induced protective host immunity by eliciting tumor-specific T-cell responses. Similarly, tumor vaccination experiments showed that irradiated tumor cells (IgE loaded by biotin-avidin bridging) conferred protective immunity at doses 100-fold lower than the corresponding control cells without IgE. Finally, in vivo depletion of eosinophils or T cells abrogated IgE-driven tumor growth inhibition. These results demonstrate that IgEs targeted on tumor cells not only possess a curative potential but also confer long-term antitumor immunity and that IgE-driven antitumor activity is not restricted to the activation of innate immunity effector mechanisms but also results from eosinophil-dependent priming of a T-cell-mediated adaptive immune response. This suggests a potential role for IgEs in the design of new cell-based tumor vaccines.

Abstract
Atrial natriuretic factor (ANF) is a 28 amino acid peptide secreted by the atrial cardiocytes. Clearance is via the lung (50%) and the liver (25%). The main stimulus to ANF secretion is atrial distension but vasoconstrictors, sympathetic stimulation, catecolamines and tachycardia are able to enhance its circulating blood levels. ANF blood concentrations were measured during orthotopic liver transplantation in six postnecrotic cirrhotic patients. Significant increases in ANF blood levels occurred at the end of the anhepatic phase (P < or = 0.02 vs baseline) associated with low cardiac filling pressures (P < or = 0.02 vs baseline) and increased systemic vascular resistances (P < or = 0.02 vs preanhepatic phase). Aldosterone blood levels showed a similar behaviour, increasing significantly (P > or = 0.001 vs baseline) at the end of the anhepatic phase. ANF fell after reperfusion of the graft and returned towards baseline values at the end of the procedure. Since most of the total body clearance of ANF is performed by the lungs, its sharp increase at the end of the anhepatic phase could be considered a counterregulatory response to vasoconstricting stimulation and to fluid-sparing mechanisms in the presence of relative hypovolaemia. Its decrease after reperfusion could be related to volume normalization and partly to the enhanced clearance performed by the newly grafted liver.
