Abstract
Mosquito-borne arboviruses diseases cause a substantial public health burden within their expanding range. To date, their control relies on synthetic insecticides and repellents aimed to control the competent mosquito vectors. However, their use is hampered by their high economic, environmental, and human health impacts. Natural products may represent a valid eco-friendly alternative to chemical pesticides to control mosquitoes, and mosquito-borne parasitic diseases. The aim of this work was to combine the chemical and sensorial profiles with the bioactivity data of Salvia spp. essential oils (EOs) to select the most suitable EO to be used as a repellent and insecticide against the invasive mosquito Aedes albopictus (Diptera: Culicidae), vector of pathogens and parasites, and to describe the EOs smell profile. To do this, the EOs of four Salvia species, namely S. dolomitica, S. dorisiana, S. sclarea, and S. somalensis were extracted, chemically analyzed and tested for their bioactivity as larvicides and repellents against Ae. albopictus. Then, the smell profiles of the EOs were described by a panel of assessors. The LC50 of the EOs ranged from 71.08 to 559.77 μL L−1 for S. dorisiana and S. sclarea, respectively. S. sclarea EO showed the highest repellence among the tested EOs against Ae. albopictus females (RD95 = 12.65 nL cm−2), while the most long-lasting, at the dose of 20 nL cm−2, was S. dorisiana (Complete Protection Time = 43.28 ± 3.43 min). S. sclarea EO showed the best smell profile, while S. dolomitica EO the worst one with a high number of off-flavors. Overall, all the EOs, with the exception of the S. dolomitica one, were indicated as suitable for “environmental protection”, while S. dorisiana and S. sclarea were indicated as suitable also for “Body care”.

Abstract
BACKGROUND Adult skin fibroblasts represent the most common starting cell type used to generate human induced pluripotent stem cells (F-hiPSC) for clinical studies. Yet, a foetal source would offer unique advantages, primarily the absence of accumulated somatic mutations. Herein, we generated hiPSC from cord blood multipotent mesenchymal stromal cells (MSC-hiPSC) and compared them with F-hiPSC. Assessment of the full activation of the pluripotency gene regulatory network (PGRN) focused on circular RNA (circRNA), recently proposed to participate in the control of pluripotency. METHODS Reprogramming was achieved by a footprint-free strategy. Self-renewal and pluripotency of cord blood MSC-hiPSC were investigated in vitro and in vivo, compared to parental MSC, to embryonic stem cells and to F-hiPSC. High-throughput array-based approaches and bioinformatics analyses were applied to address the PGRN. FINDINGS Cord blood MSC-hiPSC successfully acquired a complete pluripotent identity. Functional comparison with F-hiPSC showed no differences in terms of i) generation of mesenchymal-like derivatives, ii) their subsequent adipogenic, osteogenic and chondrogenic commitment, and iii) their hematopoietic support ability. At the transcriptional level, specific subsets of mRNA, miRNA and circRNA (n = 4,429) were evidenced, casting a further layer of complexity on the PGRN regulatory crosstalk. INTERPRETATION A circRNA map of transcripts associated to naïve and primed pluripotency is provided for hiPSC of clinical-grade foetal origin, offering insights on still unreported regulatory circuits of the PGRN to consider for the optimization and development of efficient differentiation protocols for clinical translation. FUNDING This research was funded by Ricerca Corrente 2012-2018 by the Italian Ministry of Health.

Abstract
Background/Aims Endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) is the go-to method for obtaining samples from gastrointestinal tract and pancreatic lesions. When the transduodenal approach is utilized, the use of a more flexible needle, such as a nitinol 19-gauge (G) needle, has been recommended. The aim of this study was to evaluate the feasibility and accuracy of 19-G flexible aspiration needles in obtaining samples from solid lesions through a transduodenal approach.
Methods This was a retrospective analysis of prospectively collected data from eight Italian endoscopy centers. Consecutive patients with solid lesions who underwent transduodenal EUS-FNA with a 19-G flexible needle were included.
Results A total of 201 patients were enrolled. According to histology, EUS, radiology and 12 months of follow-up, 151 patients had malignant lesions and 50 patients had benign lesions. EUS-FNA was feasible in all cases. An adequate histologic sample was obtained in all except eight cases (96.1%). The sensitivity of EUS-FNA was 92.1% (95% confidence interval [CI], 86.8%–95.7%), and the specificity was 100% (95% CI, 90.5%–100%). The positive predictive value was 100% (95% CI, 93.4%–100%), and the negative predictive value was 74% (95% CI, 62.8%–82.7%). The diagnostic accuracy was 93.5% (95% CI, 89.2%–96.5%).
Conclusions The transduodenal approach for obtaining samples from solid lesions using a 19-G flexible needle seems feasible and accurate.

Abstract
Short-term administration of the entry inhibitor myrcludex-B (MyrB) has been shown to be safe and effective in phase II studies in patients coinfected with hepatitis B virus (HBV) and hepatitis delta virus (HDV). However, its effectiveness and safety are unknown during long-term and high-dose treatment of patients with compensated cirrhosis in real-life settings. Herein, we describe the first 3 European patients with HDV-related compensated cirrhosis who were treated with MyrB 10 mg/day for 48 weeks as a compassionate therapy. Liver function tests, bile acids, and virological markers were monitored every 4 weeks. HBV/HDV-specific T cell quantity (up to 48 and 36 weeks) and HBV RNA levels were also assessed in 2 cases. During MyrB treatment, HDV RNA levels progressively declined from 4.4 and 5.6 logs IU/ml to undetectability in 2 cases, and from 6.8 log copies/ml to 500 copies/ml for the other patient. Alanine aminotransferase normalised after 20, 12 and 28 weeks, respectively. A significant improvement in features of portal hypertension, liver function tests and alpha-fetoprotein levels were documented in 2 cases. In the male patient with histological and clinical stigmata of autoimmune hepatitis, IgG and immunoglobulins rapidly normalised. No significant changes in HBV surface antigen levels and circulating HBV/HDV-specific T cells were demonstrated; HBV DNA and HBV RNA levels remained undetectable throughout the study period. MyrB was well tolerated; patients remained fully asymptomatic despite a significant increase of bile acids. In conclusion, this report shows excellent safety and effectiveness of a 48-week course of MyrB 10 mg/day, combined with tenofovir disoproxil fumarate, for the treatment of HDV-related compensated cirrhosis.

Abstract
BACKGROUND AND OBJECTIVE EUS-guided fine-needle biopsy has become the standard for tissue sampling. A new 20G ProCore™ (PC) needle has been developed to overcome the limitations of tissue acquisition of the smaller needles (22G, 25G) and the rigidity of the larger one (19G). The aim of this study is to assess the performance of the 20G PC needle. MATERIALS AND METHODS Patients who underwent EUS-guided tissue acquisition with the 20G PC needle of pancreatic and extra-pancreatic mass lesions were retrospectively identified at three Italian centers (Bologna, Fermo, and Palermo). Diagnostic adequacy, accuracy, and tissue core acquisition were the outcome measures. All the cases were performed without rapid on-site evaluation. RESULTS A total of 384 patients with pancreatic (62.2%) and extra-pancreatic lesions were included in the study. For pancreatic lesions, adequacy, accuracy, sensitivity, and specificity were 92.4%, 91.5%, 90.8%, and 100%, respectively, with a number needed to misdiagnose (NNM) of 11.8. The tissue core was obtained in 72% of cases. Transduodenal approach was performed in 150 pancreatic lesions; adequacy, accuracy, and tissue core acquisition were 88.7%, 90%, and 66%, respectively (NNM 10). For extrapancreatic lesions, adequacy, accuracy, sensitivity, specificity, and tissue core sampling were 95.3%, 95.3%, 92.6%, 100%, and 84.5% (NNM 21.3). CONCLUSIONS The 20G PC needle showed high diagnostic adequacy and accuracy, regardless the access route.

Abstract
BACKGROUND AND AIM Tissue acquisition in pancreatic cystic lesions (PCL) is the ideal method for diagnosis and risk stratification for malignancy of these lesions. Direct sampling from the walls of PCL with different devices has shown better results than cytology from cystic fluid. We carried out a retrospective, multicenter study to evaluate the feasibility, safety, and diagnostic yield of a micro-forceps, specifically designed to be used through a 19-gauge needle after endoscopic ultrasonography (EUS)-guided puncture of PCL. METHODS We retrospectively collected data from patients who underwent EUS-through-the-needle biopsy (EUS-TTNB) in PCL at six referral centers. RESULTS The sampling procedure was carried out in 56 patients (mean age 57.5 ± 13.1 years, M:F 17:39), and was technically successful in all of them (100%; 95% confidence interval [CI], 94-100%). Adverse events occurred in 9/56 (16.1%; 95% CI, 8-28%) patients, with self-limited intracystic hemorrhage the most common (7/56, 12.5%; 95% CI, 5-24%). All adverse events were mild, and resolved without any specific intervention. Specimens were considered adequate for histological diagnosis in 47/56 (83.9%; 95% CI, 72-92%). In two of these patients, despite the histological adequacy, a diagnosis could not be reached. In two other cases, a specimen sufficient for a cytological diagnosis was obtained. Overall diagnostic yield by combining cytological and histological samples was 47/56 (83.9%; 95% CI, 72-92%). CONCLUSION EUS-TTNB with micro-forceps in PCL is feasible, safe, and has a high diagnostic yield. Future prospective studies are needed to better assess the clinical impact of EUS-TTNB on the management of PCL.

Abstract
The evaluation of the essential oil (EO) profile of several cultivars of Rosmarinus officinalis, usually not used for food, and the assessment of their antioxidant activity as potential sources of natural antioxidants were studied in this work. Five different cultivars of Rosmarinus officinalis: R. officinalis ‘Alba'; R. officinalis ‘Blue Rain'; R. officinalis ‘Corsican Blue'; R. officinalis ‘Israeli'; R. officinalis ‘Majorca Pink’ and one hybrid of rosemary, Rosmarinus x lavandulaceus Noë, cultivated at CREA Sanremo (Italy), were hydrodistilled separately and the obtained EOs were analysed by GC-MS. Monoterpenes predominated in all the EO profiles but oxygenated monoterpenes were the most abundant constituents in R. officinalis ‘Blue Rain’, R. officinalis ‘Corsican Blue’, R. officinalis ‘Israeli’ and R. officinalis ‘Majorca Pink’. R. x lavandulaceus Noë and R. officinalis ‘Alba’ showed percentages of monoterpene hydrocarbons and oxygenated monoterpenes very similar. α-pinene, camphene, 1,8-cineole, camphor, borneol, verbenone, isobornyl acetate and β-caryophyllene were the main constituents present in all the plant cultivars, even though in different percentages. Myrcene predominate in R. officinalis ‘Alba’ (30.3 %), 1,8 cineol in R. officinalis ‘Blue Rain’ and R. officinalis ‘Israeli’ (21.9% and 26.4%, respectively), while camphor was the main constituent in R. officinalis ‘Majorca Pink’ (42.5%) and in R. x lavandulaceus (24.2%). R. officinalis ‘Corsican Blue’ showed similar amount of the three main components, verbenone, camphor and isobornyl acetate (18.5% >18.2% >15.4%, respectively). All the EOs were also tested for their antioxidant activity using the ferric reducing antioxidant power (FRAP) method and the stable radical DPPH. R. x lavandulaceus Noë showed the highest antioxidant activity, two folds more than that observed in R. officinalis ‘Israeli’.

Abstract
Helichrysum genus consists of about 600 species widespread throughout the world, especially in South Africa and in the Mediterranean area. In this study the aroma profile (HS-SPME) and the EO compositions of seven Helichrysum species (H. cymosum, H. odoratissimum, H. petiolare, H. fontanesii, H. saxatile, H. sanguineum, and H. tenax) were evaluated. All the plants were grown in Italy under the same growth conditions. The volatile constituents, particularly monoterpenes, depended by the plant's genotype and ecological adaptation. This study represents the first headspace evaluation on the selected plants and the results evidenced that monoterpenes represented the main class of constituents in five of the seven species analysed (from 59.2% to 95.0%). The higher content in sesquiterpene hydrocarbons was observed in the Mediterranean species of H. sanguineum (68.0%). Only H. saxatile showed relative similar abundance of monoterpenes and sesquiterpene hydrocarbons. The essential oil composition of the majority of examined species are characterised by high percentage of sesquiterpenes (especially β-caryophyllene and δ-cadinene) ranging from 51.3% to 92.0%, except for H. cymosum, H. tenax, and H. sanguineum leaves where monoterpenes predominated (from 51.7% to 74.7%).

Abstract
Essential oils (EOs) from Salvia dolomitica and Salvia somalensis, widely employed in the cosmetic and perfume industry, were analyzed for composition and tested against bacterial and fungal pathogens isolated from clinical and environmental specimens. The analyses were carried out against Staphylococcus aureus, Staphylococcus pseudointermedius, Pseudomonas aeruginosa, Escherichia coli, Streptococcus canis, Streptococcus pyogenes, Klebsiella pneumoniae, Proteus mirabilis, Microsporum canis, Microsporum gypseum, Trichophyton mentagrophytes, Aspergillus niger, Aspergillus flavus, Candida albicans, Candida krusei, Mucor sp. and Trichothecium roseum. Both EOs showed similar percentages of total monoterpenes and sesquiterpene hydrocarbons. The main constituents were 1,8-cineole and β-caryophyllene in S. dolomitica and bornyl acetate and camphor in S. somalensis. The selected EOs have no relevant antifungal or antibacterial activities if compared to conventional drugs.

Abstract
Extracellular matrix (ECM) plays a fundamental role in tissue architecture and homeostasis and modulates cell functions through a complex interaction between cell surface receptors, hormones, several bioeffector molecules, and structural proteins like collagen. These components are secreted into ECM and all together contribute to regulate several cellular activities including differentiation, apoptosis, proliferation, and migration. The so-called "matricellular" proteins (MPs) have recently emerged as important regulators of ECM functions. The aim of our review is to consider all different types of MPs family assessing the potential relationship between MPs and survival in patients with pancreatic ductal adenocarcinoma (PDAC). A systematic computer-based search of published articles, according to the Preferred Reporting Items for Systematic reviews and Meta-Analysis (PRISMA) Statement issued in 2009 was conducted through Ovid interface, and literature review was performed in May 2017. The search text words were identified by means of controlled vocabulary, such as the National Library of Medicine's MESH (Medical Subject Headings) and Keywords. Collected data showed an important role of MPs in carcinogenesis and in PDAC prognosis even though the underlying mechanisms are still largely unknown and data are not univocal. Therefore, a better understanding of MPs role in regulation of ECM homeostasis and remodeling of specific organ niches may suggest potential novel extracellular targets for the development of efficacious therapeutic strategies.

Abstract
Secondary metabolites may be affected by arbuscular mycorrhizal fungi (AMF), which are beneficial symbionts associated with the roots of most plant species. Bituminaria bituminosa (L.) C.H.Stirt is known as a source of several phytochemicals and therefore used in folk medicine as a vulnerary, cicatrising, disinfectant agent. Characteristic metabolites found in B. bituminosa are furanocoumarins and pterocarpans, which are used in cosmetics and as chemotherapeutic agents. Here we address the question whether AMF inoculation might affect positively the synthesis of these phytochemicals. B. bituminosa plants were inoculated with different AMF and several metabolites were assessed during full vegetative stage and flowering phase. Pigments (chlorophylls and carotenoids), polyphenols and flavonoids were spectrophotometrically determined; specific isoflavones (genistein), furanocoumarins (psoralene and angelicin), pterocarpans (bitucarpin A and erybraedin C) and plicatin B were assessed with HPLC; leaf volatile organic compounds were analysed using SPME and identified by GC-MS. During the vegetative stage, the inoculated plants had a high amount of furanocoumarins (angelicin and psoralen) and pterocarpans (erybraedin C and bitucarpin A). The analysis of volatile organic compounds of inoculated plants showed different chemical composition compared with non-mycorrhizal plants. Given the important potential role played by furanocoumarins and pterocarpans in the pharmaceutical industry, AMF inoculation of B. bituminosa plants may represent a suitable biotechnological tool to obtain higher amounts of such metabolites for pharmaceutical and medicinal purposes.

Abstract
Pancreatic ductal adenocarcinoma (PDAC) is expected to become the second leading cause of cancer-associated death in the next decade or so. It is widely accepted that tumorigenesis is linked to specific alterations in key genes and pancreatic neoplasms are some of the best characterized at the genomic level. Recent whole-exome and whole-genome sequencing analyses confirmed that PDAC is frequently characterized by mutations in a set of four genes among others: KRAS, TP53, CDKN2A/p16, and SMAD4. Sequencing, for example, is the preferable technique available for detecting KRAS mutations, whereas in situ immunochemistry is the main approach for detecting TP53 gene alteration. Nevertheless, the diagnosis of PDAC is still a clinical challenge, involving adequate acquisition of endoscopic ultrasound (EUS)-guided fine-needle aspiration (FNA) and specific pathological assessment from tissue architecture to specific biomolecular tests. The aim of the present review is to provide a complete overview of the current knowledge of the biology of pancreatic cancer as detected by the latest biomolecular techniques and, moreover, to propose a paradigm for strict teamwork collaboration in order to improve the correct use of diagnostic sources.

Abstract
The first phytochemical investigation of the aerial parts of Bituminaria basaltica, an endemic species from the Aeolian Islands, led to the isolation and identification of eight compounds including plicatin B (3), two furanocoumarins: angelicin (1), psoralen (2), three pterocarpans: erybraedin C (4), 3,9-dihydroxy-4-isoprenyl-pterocarpan (5), bitucarpin A (8) and two flavonoid glycosides: isoorientin (6), daidzin (7). Their structures were elucidated by spectroscospic techniques and compared with data reported in the literature. Sesquiterpenes characterised the essential oil composition of the title plant where β-caryophyllene and germacrene D were the main constituents.

Abstract
In a recent work, our group showed the existence of two distinct mesenchymal stem cell (MSC) subsets within human umbilical cord blood. One less proliferative and short-living (SL-CBMSC), the other with higher growth rate and long-living (LL-CBMSC), and therefore better suited for regenerative medicine applications. We examined whether LL-CBMSC possess peculiar paracrine properties able to affect angiogenesis or inflammatory processes. It was shown for the first time that pro-angiogenic, proliferation-stimulating and tissue repairing factors were released at high level not only as soluble cytokines, but also as mRNA precursors embedded in membrane vesicles. The combination of this primary (proteic factors interacting with surface receptors) and delayed (mRNA transferred and translated via vesicle fusion and cargo release) interaction in endothelial target cells resulted in strong blood vessel induction with the development of capillary-like structures. In addition, LL-CBMSC dynamically modulated their release of pro-angiogenic and anti-inflammatory factors in an in vitro model of damage. In conclusion, LL-CBMSC synthesize and secrete multiple factors that may be attuned in response to the status of the target cell, a crucial requisite when paracrine mechanisms are needed at onset of tissue regeneration.

Abstract
The in vitro activity of twenty chemically defined essential oils (EOs) obtained from Boswellia sacra, Citrus bergamia, C. limon, C. medica, Cinnamomum zeylanicum, Eucalyptus globulus, Foeniculum vulgare, Helichrysum italicum, Illicium verum, Litsea cubeba, Mentha spicata, Myrtus communis, Ocimum basilicum, Origanum majorana, O. vulgare, Pelargonium graveolens, Rosmarinus officinalis, Santalum album, Satureja montana, and Thymus serpyllum was assayed against clinical animal isolates of Microsporum canis, Trichophyton mentagrophytes, T. erinacei, T. terrestre and Microsporum gypseum, main causative agents of zoonotic and/or environmental dermatophytoses in humans. Single main components present in high amounts in such EOs were also tested. Different dermatophyte species showed remarkable differences in sensitivity. In general, more effective EOs were T. serpyllum (MIC range 0.025%-0.25%), O. vulgare (MIC range 0.025%-0.5%) and L. cubeba (MIC range 0.025%-1.5%). F. vulgare showed a moderate efficacy against geophilic species such as M. gypseum and T. terrestre. Among single main components tested, neral was the most active (MIC and MFC values ≤ 0.25%). The results of the present study seem to be promising for an in vivo use of some assayed EOs.

Abstract
BACKGROUND The Center for Transfusion Medicine, Cell Therapy and Cryobiology, Milan, Northern Italy, is the headquarter of the POLI-MI biobank. It co-ordinates the biobank activities of the Fondazione Ca' Granda Ospedale Maggiore Policlinico of Milan. Such activities require specific safeguarding of donors' rights and protection of sensitive and genetic data. The Fondazione Ca' Granda Ospedale Maggiore Policlinico has set up a project on informed consent with the aim of developing awareness and understanding of this issue. Within this project, it has been decided to evaluate how consent for biobanking material is expressed. DESIGN AND METHODS The aim of the study was to evaluate the quality and completeness of consent to biobanking in the POLI-MI biobank. This was a retrospective study carried out in 2012 on samples of consent declarations collected by biobank units in 2011. Some units used a single, standard consent model available from a previous POLI-MI biobank workgroup. Other units used models which had been previouly formulated. Evaluation was made using a form that indicated the essential elements of consent. RESULTS A total of 48 consent declarations were collected using the single, standard model and 84 were collected using other models. The consent declarations that used the single, standard model were found to be the most complete and were filled in better than other models. CONCLUSIONS Progressive adoption of a simple, standard consent model is expected to improve the quality of consent acquisition. Regular audit of the compliance of consent practices with ethical and legal requirements is mandatory to improve the quality of research biobanking.

Abstract
Eosinophilic enteritis, an increasing recognized condition, is rare and often presents with non-specific symptoms. We report a case of a 46-year old female who presented with acute onset abdominal pain and nausea associated with ascites, small bowel thickening and peripheral eosinophilia. Diagnosis was confirmed by biopsies taken at esophagogastroduodenoscopy demonstrating diffuse infiltration by inflammatory cells, mainly eosinophils. Appropriate therapy was instituted. The patient recovered well and was symptom-free at 1-month follow up. In this report, we discuss the clinical presentation and the diagnostic criteria of the eosinophilic enteritis, and examine the pathophysiological theories and therapeutic strategies. The relevant literature on eosinophilic enteritis is summarized.

Abstract
The chemical composition of the essential oils obtained from the leaves and roots of Cochlospermum angolense (Welw) growing wild in Angola was analyzed for the first time by capillary gas chromatography (GC) and gas chromatography/mass spectrometry (GC-MS). The investigation led to the identification of 67 and 130 compounds from the leaves and roots, respectively. Both oils were strongly characterized by the presence of sesquiterpenoids (68.8% in the leaves and 53.2% in the roots), while monoterpenoids were present in minor percentages (9.8% in the leaves and 26.2% in the root). The main constituents of the leaves were germacrene D (9.4%), α-cadinol (7.4%) and 10- epi-cubenol (6.2%), while the most abundant compounds in the root essential oil were the sesquiterpenes β-caryophyllene (19.7%) and isoborneol (6.6%). The analysis by HS-SPME of the roots, leaves, fruits and seeds were also reported for the first time. Different volatile profiles were detected.

Abstract
BACKGROUND Volume reduction of cord blood units decreases the cost of cryogenic storage. This study reports the analysis of a 10-year quality control program of a semiautomated cord blood volume reduction procedure. STUDY DESIGN AND METHODS Cord blood was collected in a plastic bag containing 29 mL citrate-phosphate-dextrose, centrifuged at 2124 x g for 12 minutes, and processed with a semiautomated device. The procedure was aimed at removing most red blood cells and plasma and concentrating hematopoietic progenitors in the buffy coat (BC), thus reducing the unit volume and saving cryogenic space. Finally, the BC was cryopreserved with an equal volume of 20 percent dimethyl sulfoxide. Total nucleated cells (TNCs) were counted before and after processing in the 4311 units banked from 1998 through 2007, whereas CD34+ cells and colony-forming units-granulocyte-macrophage (CFU-GM) were counted in 420 random units from 2001 through 2007. RESULTS Mean postvolume reduction annual recoveries of TNCs, CD34+ cells, and CFU-GM ranged from 82.8 +/- 12.3 (standard deviation) to 91.4 +/- 6.4 percent, from 87.8 +/- 14.1 to 95.2 +/- 23.8 percent, and from 101.5 +/- 51.4 to 117.8 +/- 59.5 percent, respectively. Very strong correlations were found (r > 0.87) between postprocessing versus preprocessing TNCs, CD34+ cells, and CFU-GM; a moderate correlation between initial TNC count and unit's volume (r = 0.51); and no correlation between TNC percentage of recovery in the BC and initial unit's volume. The latter data indicate that most TNCs concentrate in the BC. CONCLUSIONS The semiautomated procedure of cord blood unit volume reduction used in this study provides high and stable cellular recoveries during several years of routine cord blood banking.

Abstract
A model of a university hospital facility for biobanking and clinical grade cell manipulation is described. The facility is based on the model of the Biological Resource Center described by the Organisation for the Economic Cooperation and Development in 1999. This model integrates several critical aspects of collection, characterization, storage and use of biological materials for research purposes and therapeutic applications, thus providing potential advantages of optimizing the use of resources, improving standardization, protecting the rights of both donors and recipients of biological materials, and facilitating international cooperation.

Abstract
We developed a laboratory model of a unit of hemopoietic progenitor cells (mock-HPC unit) suitable for the validation of HPC cryopreservation procedures. The project was prompted by the practical and ethical difficulty of using real HPC units collected from healthy donors and patients for validation purposes. Mock-HPC units of different volumes ranging from about 120 to about 540mL were prepared by pooling a routinely discarded by product of our procedure to prepare platelet concentrates from buffy-coats, a standard procedure in most blood centers in Europe. Five ABO/Rh identical buffy coats each of 50mL volume, obtained from 450mL whole blood units by hard spin, were pooled with 300mL of a commercial platelet additive solution. After soft spin, the supernatant platelet concentrate pool was removed. The bottom fraction of this procedure, which contains RBC, WBC, HPC and platelets, constitutes a mock-HPC unit of about 120mL volume. Several bottom fractions may be pooled to obtain a mock-HPC unit of the desired volume. We used 20 mock-HPC units to validate an automatic procedure of HPC cryopreservation with a controlled rate freezer. In particular, we documented the standardization of critical points of the cooling profile, such as the correspondence of the crystallization phase with the theoretical freezing temperature of the product, the temperature peak rise above the theoretical freezing temperature of -5.7 degrees C and the automatic achievement in the chamber of a constant minimum temperature during supercooling (about -37 degrees C) with mean chamber loading volumes ranging from 231.8 to 1027.2mL.

Abstract
Beside substantial progress in treatment of chronic hepatitis C (CHC) particular patients (genotype 1/4, high viral load, previous nonresponse, cirrhosis) remain difficult to treat. The aim of our pilot randomized study was to compare efficacy and tolerability of standard doses of Peginterferon alpha-2b + ribavirin with higher doses of Peginterferon alpha-2b administered twice weekly + ribavirin. Sixty-five outpatients with CHC were subsequently enrolled. Group A (n = 22) received recommended doses of Peginterferon alpha-2b and group B (n = 43), received high doses twice weekly. Groups were comparable for baseline characteristics. All genotype 1/4 patients had high baseline viraemia. Sustained virological response (SVR) was significantly higher in group B among naïve patients (72%vs 25%, P = 0.024). A significantly higher rate of SVR was observed in group B both considering only genotype 1/4 patients, (46%vs 13%, P = 0.03) and grouping together genotype 1/4 naive and relapsers (57%vs 11%, P = 0.039). Discontinuation rate was 32% (7 of 22) in group A and 21% (9 [corrected] of 43) in group B. Our response rates are the highest reported for genotype 1/4 with high viraemia. Our pilot study supports the need of randomized studies to evaluate both viral kinetics and efficacy of high dose and twice weekly administration of Peginterferon alpha-2b in genotype 1/4 patients with high viraemia who may need personalized treatment schedules.

Abstract
AIM: To determine the role of interferon (IFN) with or without ribavirin in preventing or delaying hepatocellular carcinoma (HCC) development in patients with hepatitis C virus (HCV) related cirrhosis. Data on the preventive effect of IFN plus ribavirin treatment are lacking.
METHODS: A total of 101 patients (62 males and 39 females, mean age 55.1 ± 1.4 years) with histologically proven HCV related liver cirrhosis plus compatible biochemistry and ultrasonography were enrolled in the study. Biochemistry and ultrasonography were performed every 6 mo. Ultrasound guided liver biopsy was performed on all detected focal lesions. Follow-up lasted for 5 years. Cellular proliferation, evaluated by measuring Ag-NOR proteins in hepatocytes nuclei, was expressed as AgNOR-Proliferative index (AgNOR-PI) (cut-off = 2.5). Forty-one patients (27 males, 14 females) were only followed up after the end of an yearly treatment with IFN-alpha2b (old treatment control group = OTCG). Sixty naive patients were stratified according to sex and AgNOR-PI and then randomized in two groups: 30 were treated with IFN-alpha2b + ribavirin (treatment group = TG), the remaining were not treated (control group = CG). Nonresponders (NR) or relapsers in the TG received further IFN/ribavirin treatments after a 6 mo of withdrawal.
RESULTS: AgNOR-PI was significantly lowered by IFN (P < 0.001). HCC incidence was higher in patients with AgNOR-PI > 2.5 (26% vs 3%, P < 0.01). Two NR in the OTCG, none in the TG and 9 patients in the CG developed HCC during follow-up. The Kaplan-Mayer survival curves showed statistically significant differences both between OTCG and CG (P < 0.004) and between TG and CG (P < 0.003).
CONCLUSION: IFN/ribavirin treatment associated with re-treatment courses of NR seems to produce the best results in terms of HCC prevention. AgNOR-PI is a useful marker of possible HCC development.

Abstract
AIM: To explore the prevalence of autoimmune gastritis in chronic hepatitis C virus (HCV) patients and the influence of a-interferon (IFN) treatment on autoimmune gastritis.
METHODS: We performed a prospective study on 189 patients with positive anti-HCV and viral RNA enrolled in a 12-month IFN protocol. We evaluated: a) the baseline prevalence of autoimmune gastritis, b) the impact of IFN treatment on development of biochemical signs of autoimmune gastritis (at 3, 6 and 12 mo), c) the evolution after IFN withdrawal (12 mo) in terms of anti-gastric-parietal-cell antibodies (APCA), gastrin, anti-thyroid, and anti-non-organ-specific antibodies.
RESULTS: APCA positivity and 3-fold gastrin levels were detected in 3 (1.6%) and 9 (5%) patients, respectively, at baseline, in 25 (13%) and 31 (16%) patients at the end of treatment (both P < 0.001, vs baseline), and in 7 (4%) and 14 (7%) patients 12 mo after withdrawal (P = 0.002 and P = 0.01 respectively, vs baseline; P = not significant vs end of treatment). The development of autoimmune gastritis was strictly associated with the presence of autoimmune thyroiditis (P = 0.0001), no relationship was found with other markers of autoimmunity.
CONCLUSION: In HCV patients, IFN frequently precipitates latent autoimmune gastritis, particularly in females. Following our 12-month protocol, the phenomenon generally regressed. Since APCA positivity and high gastrin levels are associated with the presence of antithyroid antibodies, development of autoimmune thyroiditis during IFN treatment may provide a surrogate preliminary indicator of possible autoimmune gastritis to limit the need for invasive examinations.

Abstract
AIM To investigate the safety and efficacy of long-term combination therapy with alpha interferon and lamivudine in non-responsive patients with anti-HBe-positive chronic hepatitis B. METHODS 34 patients received combination treatment (1 month lamivudine, 12 month lamivudine+interferon, 6 month lamivudine), 24 received lamivudine (12 months), 24 received interferon (12 months). Interferon was administered at 6 MU tiw and lamivudine at 100 mg orally once daily. Patients were followed up for 6 months after treatment. RESULTS At the end of treatment, HBV DNA negativity rates were 88 % with lamivudine+interferon, 99 % with lamivudine and 55 % with interferon, (P=0.004, combination therapy vs. interferon, and P=0.001 lamivudine vs. interferon), and serum transaminase normalization rates were 84 %, 91 % and 53 % (P=0.01 combination therapy vs. interferon, and P=0.012 lamivudine vs. interferon). Six months later, HBV DNA negativity rates were 44 % with lamivudine+interferon, 33 % with lamivudine and 25 % with interferon, and serum transaminase normalization rates were 61 %, 42 % and 45 %, respectively, without statistical significance. No YMDD variants were observed with lamivudine+interferon (vs. 12 % with lamivudine). The combination therapy appeared to be safe. CONCLUSION Although viral clearance and transaminase normalization are slower with long-term lamivudine+interferon than that with lamivudine alone, the combination regimen seems to provide more lasting benefits and to protect against the appearance of YMDD variants. Studies with other regimens regarding sequence and duration are needed.

Abstract
BACKGROUND Little is known of the incidence of hepatitis C virus (HCV) infection, and the frequency of spontaneous viral clearance in the general population is unknown. We conducted an epidemiological study in two Apennine towns in northern Italy. METHODS Anti-HCV (ELISA and RIBA third generation) and HCV-RNA by polymerase chain reaction were tested in thawed sera from an adult general population of Loiano-Monghidoro in 1986 and 1996, obtained in the context of the MICOL (Multicenter Italian Study on Cholelithiasis). In 1999, anti-HCV positive subjects and sex and age matched controls were recalled in order to identify risk factors for acquiring HCV infection and to assess the family composition of anti-HCV+ subjects. RESULTS For 1646 subjects, sera were available from both 1986 and 1996 (mean age in 1986 43 (0.39) years). In 1986, 57 (3.46%) subjects were HCV antibody positive (HCV-Ab+). Eight new cases were recorded in 1996: adult incidence was 50.3 cases/100 000 inhabitants/year. Fifty three of 63 (84.1%) HCV-Ab+ sera were also HCV-RNA+. Genotype 2a/2c accounted for 44% and 1b for 47.0% of cases. HCV-Ab+ subjects had higher serum levels of alanine aminotransferase with respect to controls (p<0.005), as did subjects infected with genotype 1 with respect to those with genotype 2 (p<0.05). Eleven of 65 (16.9%) HCV-Ab+ subjects spontaneously cleared HCV-Ab; 7/11 also lost HCV-RNA- in both serum and leucocytes. Sixteen anti-HCV+ subjects belonged to families containing more than one infected member. Married couples accounted for 10 of these 16 subjects. In four of these five married couples, HCV genotype was identical in the two spouses. CONCLUSIONS In rural northern Italy, the adult incidence of HCV is approximately 50 cases/100 000 inhabitants/year. Our findings suggest that as many as 17% of infected subjects may spontaneously clear HCV-Ab. Interfamilial transmission seems to have a role in the spread of infection.

Abstract
BACKGROUND Ursodeoxycholic acid is currently used for the treatment of primary biliary cirrhosis at 13-15 mg/kg/day, but liver tests of some patients do not return to normal at this dose. Studies reported here were designed to test whether a higher dose of ursodeoxycholic acid than is currently used would induce still greater biliary enrichment of ursodeoxycholic acid and whether such enrichment would lead to still further improvement in liver tests in patients with early primary biliary cirrhosis. METHODS A total of 20 patients with histologically proven primary biliary cirrhosis were enrolled. Patients had early stage primary biliary cirrhosis as serum bilirubin levels were normal and the Mayo risk score 4.2 +/- 0.5. Group 1 received 600, 1200 and 1800 mg/day of ursodeoxycholic acid; group 2 received 900, 1500 and 2100 mg/day. The order of periods was randomized. Each treatment period lasted 3 months followed by a further 3 months during which a standard dose of ursodeoxycholic acid was given. At the end of each treatment period, liver tests were evaluated, and biliary bile acid pattern of duodenal bile was determined using high pressure liquid chromatography. RESULTS Biliary bile acid became enriched in ursodeoxycholic acid in direct relationship to dosage [r = 0.84, p < 0.001). At doses of 1800 mg/day (25-35 mg/kg/day), biliary ursodeoxycholic acid averaged 69 +/- 6.6%. A progressive decrease of alanine aminotransferase [p < 0.0001), aspartate aminotransferase [p < 0.001) and alkaline phosphatase [p < 0.02) was observed with increasing concentrations of ursodeoxycholic acid in bile. Biochemical liver tests showed a stronger correlation with biliary concentrations of ursodeoxycholic acid than with the administered dose. CONCLUSIONS In early primary biliary cirrhosis, higher dose ursodeoxycholic acid appears to be more effective than doses currently recommended.

Abstract
Ursodeoxycholic acid (UDCA) is used both as the treatment of choice in many cholestatic syndromes and as complementary therapy in many liver diseases. However, few dose-finding studies exist, and none has evaluated the efficacy and long-term safety of UDCA therapy in primary biliary cirrhosis (PBC). There is an open debate about UDCA's impact on the natural history of PBC, and no universal evidence of benefits on the major endpoint exists. This is perhaps due to a UDCA dosage deficit. Most clinical trials on PBC therapy have used conservative dosages of UDCA similar to those of chenodeoxycholic acid (CDCA) used for dissolution of gallstones. It may be necessary to re-evaluate the dosage of UDCA that provides the most effective treatment.

Abstract
Granulocyte colony-stimulating factor (G-CSF) enhances neutrophil functions in vitro and in vivo. It is known that neutrophil-derived products can alter the hemostatic balance. To understand whether polymorphonuclear leukocyte (PMN) activation, measured as PMN degranulation and phenotypical change, may be associated to hemostatic alterations in vivo, we have studied the effect of recombinant human G-CSF (rHuG-CSF) administration on leukocyte parameters and hemostatic variables in healthy donors of hematopoietic progenitor cells (HPCs). Twenty-six consecutive healthy donors receiving 10 micrograms/kg/d rHuG-CSF subcutaneously for 5 to 7 days to mobilize HPCs for allogeneic transplants were included in the study. All of them responded to rHuG-CSF with a significant white blood cell count increase. Blood samples were drawn before therapy on days 2 and 5 and 1 week after stopping rHuG-CSF treatment. The following parameters were evaluated: (1) PMN activation parameters, ie, surface CD11b/CD18 antigen expression, plasma elastase antigen levels and cellular elastase activity; (2) plasma markers of endothelium activation, ie, thrombomodulin (TM) and von Willebrand factor (vWF) antigens; (3) plasma markers of blood coagulation activation, ie, F1+2, TAT complex, D-dimer; and (4) mononuclear cell (MNC) procoagulant activity (PCA) expression. The results show that, after starting rHuG-CSF, an in vivo PMN activation occurred, as demonstrated by the significant increment of surface CD11b/CD18 and plasma elastase antigen levels. Moreover, PMN cellular elastase activity, which was significantly increased at 1 day of treatment, returned to baseline at day 5 to 6, in correspondence with the elastase antigen peak in the circulation. This change was accompanied by a parallel significant increase in plasma levels of the two endothelial and the three coagulation markers. The PCA generated in vitro by unstimulated MNC isolated from rHuG-CSF-treated subjects was not different from that of control cells from untreated subjects. However, endotoxin-stimulated MNC isolated from on-treatment individuals produced significantly more PCA compared with both baseline and control samples. All of the parameters were decreased or normal 1 week after stopping treatment. These data show that rHuG-CSF induces PMN activation and transiently affects some hemostatic variables in healthy HPC donor subjects. The clinical significance of these findings remains to be established.

Abstract
Pulmonary distress symptoms and thrombotic complications are side-effects of all-trans-retinoic acid (ATRA) therapy for remission induction in acute promyelocytic leukaemia (APL). The ATRA-induced increase of leukaemic cell adhesive molecules may be responsible. To explore this we used a functional assay to study the effect of ATRA treatment on the adhesion of blast cells to cultured human endothelial cells (EC), endothelial cell matrix (ECM), and interleukin 1beta-activated EC (IL1 + EC). NB4 cells, a maturation-inducible human promyelocytic leukaemia cell line, were treated with 1 microM ATRA or the vehicle (control), labelled with 51Cr and tested in the adhesion assay. ATRA increased NB4 adhesion to EC (P<0.01), ECM (P<0.001) and IL1 + EC (P=n.s.). An inhibition study with anti-EC adhesion receptors MoAbs indicated that anti-E-selectin, anti-VCAM-1 and anti-ICAM-1 effectively inhibited cell adhesion to IL1 + EC (18+/-7%, 45 +/-6.9% and 29+/-6% inhibition, respectively) and to unstimulated EC. Preincubation of ATRA-treated NB4 cells with MoAbs anti-VLA4 and anti-LFA1, the VCAM-1 and ICAM-1 counter-receptors respectively, resulted in a significant inhibition of adhesion. Cytofluorimetric analysis of the NB4 cell membrane molecules confirmed the increase under ATRA of VLA4, LFA1, MAC1 and ICAM-1. Therefore ATRA increases NB4 cell adhesion to the endothelium and the subendothelial matrix. These findings parallel the increment of NB4 surface adhesive molecules, among which VLA4 and LFA1 appear to play an important part. These mechanisms may contribute to the complications of ATRA therapy in APL.

Abstract
Therapy with all-trans-retinoic acid (ATRA) can rapidly improve the coagulopathy of acute promyelocytic leukemia (APL). This study was designed to evaluate whether the APL cell line NB4 induces the procoagulant activity (PCA) of human endothelial cells (ECs) in vitro, and whether this property is modified after ATRA-induced NB4 maturation. EC monolayers were incubated for 4 hours at 37 degrees C with the conditioned media (CM) of NB4 treated with 1 mumol/L ATRA (ATRA-NB4-CM) or the vehicle (control-NB4-CM). EC lysates were tested for PCA. ATRA-NB4-CM induced significantly more PCA:tissue factor (TF) than control-NB4-CM (P < .01). To identify the cause of TF induction, interleukin (IL)-1 beta antigen levels were measured in CM samples. ATRA-NB4-CM contained significantly more IL-1 beta than control-NB4-CM. EC PCA was significantly inhibited by an anti-IL-1 beta antibody. The addition to the media of 10 mumol/L ATRA counteracted the EC TF expression induced by NB4-CM. These data indicate that ATRA increases the promyelocyte-induced EC TF, partly through increased IL-1 beta production. However, ATRA can protect the endothelium from the procoagulant stimulus of leukemic cells.

Abstract
The interaction of myelin basic protein (MBP) with zinc and phosphate ions has been studied by using the emission properties of the single tryptophan residue of the protein (Trp-115). The studies have been carried out by means of both static and time-resolved fluorescence techniques. The addition of either zinc to MBP in the presence of phosphate or phosphate to MBP in the presence of zinc resulted in an increase of fluorescence intensity and a blue shift of the emission maximum wavelength. Furthermore, a concomitant increase in the scattering was also detected. Anisotropy decay experiments demonstrated that these effects are due to the formation of MBP molecules into large aggregates. A possible physiological role for such interaction is discussed.

Abstract
The interaction of some divalent cations with myelin basic protein (MBP) in buffer and in model membranes was studied by using the static fluorescence of the intrinsic tryptophan residue of the protein. Results were indicative of Zn++ ability to bind to MBP. The observed binding could facilitate the interaction of MBP with lipids and have a role in stabilizing the myelin sheath.
