Abstract
OBJECTIVE To report cross-sectionally serum levels of 25-hydroxyvitamin D [25(OH)D] in women living in Italy within 12 months from breast cancer (BC) diagnosis. METHODS Baseline data were obtained from 394 women diagnosed with primary BC, enrolled from 2016 to 2019 in a lifestyle trial conducted in Italy. Subjects' characteristics were compared between two 25(OH)D concentrations (hypovitaminosis D<20 and ≥20 ng/mL) with the Chi-squared test or Fisher's exact test for small-expected counts. Using multiple logistic regression-adjusted models, we estimated odds ratios (ORs) of hypovitaminosis D with 95% confidence intervals (CIs) in the total sample and in the unsupplemented subgroup. RESULTS Hypovitaminosis D was found in 39% of all subjects, 60% in unsupplemented subjects, and 10% in supplemented subjects. Increasing ORs of hypovitaminosis D were found with increasing body mass index, 25-30, >30, and ≥35 versus <25 kg/m2 (ORs: 2.50, 4.64, and 5.81, respectively, in the total cohort and ORs: 2.68, 5.38, and 7.08 in the unsupplemented); living in the most southern Italian region (OR 2.50, 95%CI 1.22-5.13); and with hypertriglyceridemia (OR 2.46; 95%CI 1.16-5.22), chemotherapy history (OR 1.86, 95%CI 1.03-3.38), and inversely with anti-estrogenic therapy (OR 0.43, 95%CI 0.24-0.75) in the total sample. CONCLUSIONS Hypovitaminosis D in women recently diagnosed with BC and participating in a lifestyle trial in Italy was widespread and highest with obesity, hypertriglyceridemia, and chemotherapy use. Considering that hypovitaminosis D is a risk factor for lower efficacy of bone density treatments and possibly BC mortality, our results suggest the need to promptly address and treat vitamin D deficiency.

Abstract
Background There is mounting evidence of the presence of chronic stress among children during primary school: girls and boys under the age of 15 years often experience anxiety, irritability and sleeping problems with negative consequences on scholastic climate and the spread of bullying and dropping out of school. The promotion of emotion regulation within school environment through innovative didactic methodologies represents a valuable tool for teachers and parents to reduce emotional distress and associated risk behaviours and to promote wellbeing. Aim Our research aims to explore the psychological and biological consequences of teaching emotional training in an experimental group of Italian Primary School children. Methods A sample of pupils (81 children aged between 6 and 8) was divided into an experimental group (33 subjects) and a control group (30 subjects). A further advanced group of 18 subjects, who have experienced the method in the previous school year, was also included. The experimental study lasted one school year (from October 2021 to May 2022). The following psychological tests were administered to all groups: TEC (Test of Emotion Comprehension) to measure the children's different emotional abilities and the Projective test (PT) 'A person in the rain', to identify the coping skills of children in a stressful condition. Morning salivary cortisol, IL-6 and TNF-alpha assays were conducted in all three groups. Psychological and biological tests were administered at the beginning of the study and at the end of the study. Results The MR-Anova model for TEC score showed that there was not a significant group effect [Fgroup = 2.24, p = 0.114]. Pairwise comparisons showed that mean score significantly increased only in the Experimental group (pB < 0.001) and at the end of the project there was a significant difference between Experimental group and Control group (pB = 0.012). The mean score of PT test increased significantly from baseline to the end of the project for the Experimental group (pB < 0.001) and for the Advanced group (pB = 0.004). At the end of the project, there were significant differences between the Experimental group and the Control group (pB = 0.004) and between the Advanced group and the Control group (pB < 0.001). Salivary cortisol analysis revealed a significant effect between subjects [Fgroup = 9.66; p < 0.001] and significant effects within subjects with the main effect of the time [Ftime = 35.41; p < 0.001] and the significant interaction "time x group" [Ftimexgroup = 3.38; p = 0.040]. Pairwise comparisons showed that cortisol levels decreased significantly over time only in the Experimental group (pB < 0.001). Regarding to IL-6 levels, there was not a significant effect between subjects [Fgroups = 0.0481; p = 0.953]. The mean level decreased significantly for each group from baseline to post project (pB < 0.001). With respect to TNF-alpha levels, the mean levels decreased over time for all groups (pB = 0.006 for Experimental group; pB < 0.001 either for the Advanced or Control group). Conclusion the results documented in the experimental groups who experienced didactics of emotion for at least one school year show a significant increase in children's ability to cope with reality, stress and anxiety, and an improvement of their emotional competence. Meanwhile, a significant reduction in the amount of salivary cortisol was observed in the experimental group at the end of the scholastic year; meantime a stable reduced amount of salivary cortisol in advanced group throughout the project was also observed. These findings show that an intervention through an emotional education program is able to regulate interpersonal skills and the stress axis response.

Abstract
BACKGROUND Fluid overload is a serious complication in the treatment of infants with extracorporeal membrane oxygenation (ECMO). Volume overload leads to prolonged ECMO therapy if left untreated. The renal replacement therapy of choice in pediatric patients is peritoneal dialysis or conventional dialysis using a "large" hemofiltration machine via a Shaldon catheter or directly connected to the ECMO system. This study describes the implementation of a novel minimized hemodiafiltration (HDF) system in pediatric patients on ECMO. METHODS This retrospective analysis included 13 infants up to 5 kg who underwent 15 veno-arterial (V-A) ECMO runs with HDF. A minimized HDF system is integrated into an existing ECMO system (18-mL priming volume), connected post-oxygenation to the venous line, before the ECMO pump. Two infusion pumps are attached to the inlet and outlet of the hemofilter to control the HDF system.In addition to retention values (creatine and urea) at six defined time points, flow rates, dialysis parameters, and volume withdrawal were examined, as well as the number of HDF system changes. RESULTS With a mean ECMO runtime of 156 hours, the HDF system was utilized for 131 hours. The mean blood flow through the hemofilter was 192 mL/min. The mean dialysate flow was 170 mL/h, with a mean volume deprivation of 39 mL/h. The HDF system was changed once in seven cases and twice in three cases. CONCLUSION There were no complications with the minimized HDF system in all 15 applications. It allows safe patient volume management when treating infants with ECMO, with effective elimination of urinary substances.

Abstract
BACKGROUND The aim of this study was to evaluate the long-term outcome and freedom from pulmonary valve replacement (PVR) after initial repair of tetralogy of Fallot (TOF). PATIENTS AND METHODS The cohort of 306 patients treated between 1980 and 2017 was divided into anatomical subgroups according to the diagnosis of TOF-pulmonary stenosis, TOF-pulmonary atresia and TOF-double outlet right ventricle. Patients were treated with transannular patch (TAP), valve sparing repair (VSR), or conduits from the right ventricle to the pulmonary arteries (RVPA conduits). RESULTS There were 21 deaths (6.9%), 14 being hospital deaths (4.6%) after primary correction and four deaths (1.3%) occurred after PVR. One patient died after a non-cardiac operation (0.3%). There were two late deaths (0.7%). During the past 12 years no early mortality has been observed. Ninety-one patients (30.4%) received PVR after a median of 12.1 ± 7.0 years with an early mortality of 4.4% (n = 4) and no late mortality. A significant difference in freedom from reoperation after TAP, VSR, and RVPA-conduits could be identified. Multivariate analysis displayed transannular repair (p = 0.016), primary palliation (p <0.001), the presence of major aortopulmonary collateral arteries (MAPCA; p = 0.023), and pulmonary valve Z-scores < - 4.0 (p = 0.040) as significant risk factors for PVR. CONCLUSION TOF repair has a beneficial long-term prognosis with low morbidity and mortality. Pulmonary valve Z-scores < - 4.0, transannular repair, and presence of MAPCAs are associated with earlier PVR. Non-VSRs and TOF-pulmonary atresia lead to earlier reoperation but have no negative impact on survival.

Abstract
Abstract
Background
In Italy, primary care (PC) ensures universal health coverage while containing costs. However, the assessment of its quality still remains an issue. Evidence has shown that high-quality outpatient care, through timely interventions to prevent complications of “ambulatory care sensitive conditions”, may avoid hospitalization. Aim of the study is to analyse the performance of PC in the Italian regions, using a composite and synthetic index of avoidable hospitalizations.
Methods
Hospital discharge data from 119 Italian geopolitical areas were analysed for the 2017-2019 triennium and for 2020, separately. According to the “Italian National Outcomes Evaluation Programme” methodology, 9 avoidable hospitalization indicators covering 5 nosological fields (infectious, respiratory, metabolic, cardiovascular and mental diseases) were combined in a synthetic index, calculated as the weighted mean of their standardized scores (with equal weights for each field). Using “natural breaks” technique, the areas were grouped into 5 clusters: “high”, “medium-high”, “medium”, “medium-low” and “low”.
Results
The analysis showed a marked heterogeneity at intra-regional level for the pre-pandemic triennium, with areas of homogeneity in regions with higher levels of hospitalization. The “medium” cluster, which is the widest, included 36 areas variously distributed across regions. The comparison with 2020 confirmed the geographical patterns observed for the previous triennium, despite a general reduction in hospitalizations due to the pandemic.
Conclusions
As a proxy indicator of PC quality, this index can aid decision makers in prioritizing quality improvement actions. However, in order to obtain a comprehensive evaluation, a joint reading of this index with other healthcare indicators is recommended.
Key messages
• High-quality PC is essential in maintaining appropriate hospitalization levels.
• The composite synthetic index proposed could aid PC quality assessment.

Abstract
As the SARS-CoV-2 pandemic continues to rage worldwide, the emergence of numerous variants of concern (VOC) represents a challenge for the vaccinal protective efficacy and the reliability of commercially available high-throughput immunoassays. Our study demonstrates the administration of two doses of the BNT162b2 vaccine that elicited a robust SARS-CoV-2-specific immune response which was assessed up to 3 months after full vaccination in a cohort of 37 health care workers (HCWs). SARS-CoV-2-specific antibody response, evaluated by four commercially available chemiluminescence immunoassays (CLIA), was qualitatively consistent with the results provided by the gold-standard in vitro neutralization assay (NTA). However, we could not observe a correlation between the quantity of the antibody detected by CLIA assays and their neutralizing activity tested by NTA. Almost all subjects developed a SARS-CoV-2-specific T-cell response. Moreover, vaccinated HCWs developed a similar protective neutralizing antibodies response against the EU (B.1), Alpha (B.1.1.7), Gamma (P.1), and Eta (B.1.525) SARS-CoV-2 variants, while Beta (B.1.351) and Delta (B.1.617.2) strains displayed a consistent partial immune evasion. These results underline the importance of a solid vaccine-elicited immune response and a robust antibody titre. We believe that these relevant results should be taken into consideration in the definition of future vaccinal strategies.

Abstract
OBJECTIVES Primary repair of common arterial trunk (CAT) is burdened by high mortality rates, especially in the presence of multiple risk factors. Timing, possible palliative methods, optimal management of associated cardiac lesions and handling of a poor preoperative state are still under discussion. METHODS We retrospectively analysed all patients who underwent surgery for CAT in our institution between 2008 and November 2020. We included 22 patients, 11 of whom received primary correction (PC) and 11 of whom underwent initial palliation by partial repair, leaving the ventricular septal defect open and connecting the right ventricle to the pulmonary arteries with a small valveless right ventricle-to-pulmonary artery conduit. A delayed correction (DC) was performed after 11.5 ± 3.6 months. RESULTS The overall operative mortality was 4.5%; 1 patient (affected by severe truncal valve stenosis and presenting in a poor state preoperatively) in the DC group died after palliation. The incidence of postoperative pulmonary hypertensive crisis was significantly higher in the PC group (P = 0.027). No patient from either group required postoperative extracorporeal support. Survival rates after 6 years differed slightly (PC group, 90%; DC group, 70%; log-rank = 0.270). CONCLUSIONS PC of CAT remains an optimal surgical approach for patients with an expected low mortality. However, our data support palliation and DC as a suitable alternative strategy, especially in the presence of significant risk factors like interrupted aortic arch, poor preoperative condition or complex surgical anatomy.

Abstract
This study aims to provide real-world data about starting-dose of NOACs and dose-adjustment in patients with atrial fibrillation (AF). In fact, even if new oral anticoagulation agents (NOACs) have a predictable effect without need for regular monitoring, dose-adjustments should be performed according to the summary of product information and international guidelines. We employed the Italian Medicines Agency monitoring registries comprising data on a nationwide cohort of patients with AF treated with NOACs from 2013 to 2018. Logistic regression analysis was used to evaluate the determinants of dosage choice. During the reference period, treatment was commenced for 866,539 patients. Forty-five percent of the first prescriptions were dispensed at a reduced dose (dabigatran 60.3%, edoxaban 45.2%, apixaban 40.9%, rivaroxaban 37.4%). The prescription of reduced dose was associated with older age, renal disease, bleeding risk and the concomitant use of drugs predisposing to bleeding, but not with CHA2DS2-VASc and HAS-BLED. A relative reduction of the proportion of patients treated with low dosages was evident overtime for dabigatran and rivaroxaban; whereas prescription of low dose apixaban and edoxaban increased progressively among elderly patients. Evidence based on real-world data shows a high frequency of low dose prescriptions of NOACs in AF patients. Except for older age, renal disease, bleeding risk and the concomitant use of drugs predisposing to bleeding, other factors that may determine the choice of reduced dose could not be ascertained. There may be potential under-treatment of AF patients, but further evaluation is warranted.

Abstract
Infective endocarditis (IE) is nowadays one of the most challenging disease in cardiac surgery because of its multifaceted clinical and anatomical presentation. Despite the many clinical and surgical advances achieved in the past 60 years, there is a lack of evidence regarding the ideal strategy. The present review aims to investigate and highlight two main novel concepts for the decision-making of the best substitute. Firstly, the concept of an "endocarditis team": a coordinated multidisciplinary effort in the diagnostic work-up, especially in conditions of high risk of embolization or clinical deterioration. A good "endocarditis team" has the role to overcome such problem, in order to ensure a prompt and balanced strategy. Secondly, which ethical considerations are required to drive the choice of valvular substitute. The choice of best valve substitute is a relevant issue of debate, not only with operative but also prognostic and accordingly ethical aftermaths. Many different solutions have been developed to substitute the infected valve. Among these: mechanical prosthesis (MP), biological stented prosthesis (BP), sutureless bioprosthesis and cryopreserved homografts (CHs). Patients need to be informed in detail about the technical issues pertaining the use of these valve substitute. We will discuss the evidences regarding the risk of recurrent infections or future potentially severe calcification of aortic homograft valve and wall (in other words, the failure of the homograft) and the difficulties in managing the reoperation.

Abstract
Background Atrial fibrillation (AF) is the most common cardiac arrhythmia associated with an increased risk of stroke and thromboembolism. Anticoagulation with Vitamin K antagonists (VKAs) or with novel oral anti-coagulants (NOACs) represents the cornerstone of the pharmacological treatment to reduce the risk of thromboembolism. This study aims to provide real-world data from a whole large European country about NOAC use in "non-valvular atrial fibrillation" (NVAF). Methods We analysed the Italian Medicines Agency (AIFA) monitoring registries collecting data of a nationwide cohort of patients with "NVAF" treated with NOACs. Using logistic regression analysis, baseline characteristics and treatment discontinuation information were compared among initiators of the 4 NOACs. Results In the reference period, the NOAC database collected data for 683,172 patients. The median age was 78 years with 19.5% aged 85 or older. Overall, the treatments were in accordance with guidelines. About 1/3 of patients switched from a prior VKA treatment; in the 72.3% of cases, these patients had a labile International Normalized Ratio (INR) at first prescription. The most prescribed NOAC was rivaroxaban, followed by apixaban, dabigatran and edoxaban. Conclusions This study is the largest European real-world study ever published on NOACs. It includes all Italian patients treated with NOACs since 2013 accounting for about 1/3 of subjects with AF. The enrolled population consisted of very elderly patients, at high risk of ischemic adverse events. The AIFA registries are consolidated tools that guarantee the appropriateness of prescription and provide important information for the governance of National Health System by collecting real-world data.

Abstract
BACKGROUND Aortic valve calcification is supposed to be a possible cause of embolic stroke or subclinical valve thrombosis after transcatheter aortic valve replacement (TAVR). We aimed to assess the role of aortic valve calcification in the occurrence of in-hospital clinical complications and survival after TAVR. METHODS We retrospectively analyzed preoperative contrast-enhanced multidetector computed tomography scans of patients who underwent TAVR on the native aortic valve in our center. Calcium volume was calculated for each aortic cusp, above and below the aortic annulus. Outcomes were recorded according to VARC-2 criteria. RESULTS Overall, 581 patients were included in the study (SapienXT = 192; Sapien3 = 228; CoreValve/EvolutR = 45; Engager = 5; Acurate = 111). Median survival was 4.98 years (interquartile range 4.41-5.54). Logistic regression identified calcium load beneath the right coronary cusp in left ventricular outflow tract (LVOT) as significantly associated with stroke (odds ratio [OR] 1.2; 95% confidence interval [CI] 1.03-1.3; p = 0.0019) and in-hospital mortality (OR 1.1; 95% CI 1.004-1.2; p = 0.04), whereas total calcium volume of the LVOT was associated with both in-hospital and 30 day-mortality (OR 1.2; 95% CI 1.01-1.4; p = 0.03, and OR 1.2; 95% CI 1.02-1.43; p = 0.029, respectively). Cox regression identified total calcium of LVOT (hazard ratio [HR] 1.18; 95% CI 1.02-1.38; p = 0.026), male sex (HR 1.88; 95% CI 1.06-3.32; p = 0.031), baseline creatinine clearance (HR 0.96; 95% CI 0.93-0.98; p < 0.001), and baseline severe aortic regurgitation (HR 7.48; 95% CI 2.76-20.26; p < 0.001) as risk factors associated with lower survival. CONCLUSION LVOT calcification is associated with increased risk of peri-procedural stroke and mortality as well as shorter long-term survival.

Abstract
A robust procedure for the determination of 16 US EPA PAHs in both aqueous (e.g. wastewaters, industrial discharges, treated effluents) and solid samples (e.g. suspended solids and sludge) from a wastewater treatment plant (WWTP) is presented. Recovery experiments using different percentages of organic modifier, sorbents and eluting solvent mixtures were carried out in Milli-Q water (1000 mL) spiked with a mixture of the PAH analytes (100 ng/L of each analyte). The solid phase extraction (SPE) procedures applied to spiked waste water samples (1000 mL; 100 ng/L spiking level) permitted simultaneous recovery of all the 16PAHs with yields >70% (6-13% RSD). SPE clean up procedures applied to sewage and stabilized sludge extracts, showed percent recoveries in the range 73-92% (7-13% RSD) and 71-89% (7-12% RSD), respectively. The methods were used for the determination of PAHs in aqueous and solid samples from the WWTP of Fusina (Venice, Italy). Mean concentrations, as the sum of the 16PAHs in aqueous and suspended solid samples, were found to be approx. in the 1.12-4.62 microg/L range. Sewage and stabilized sludge samples contained mean PAH concentrations, as sum of 16 compounds, in the concentration range of 1.44-1.26 mg/kg, respectively. Extraction and clean up procedures for sludge samples were validated using EPA certified reference material IRM-104 (CRM No. 912). Instrumental analyses were performed by coupling HPLC with UV-diode array detection (UV-DAD) and fluorescence detection (FLD).

Abstract
Emollients play an important role in the management of atopic dermatitis (AD). The aim of this study was to evaluate the efficacy and the “steroid-sparing” activity of an emollient cream (Xanthena® cream) in patients with mild to moderate AD. Patients were asked to apply twice a day for 7 days a cream containing hydrocortisone butyrate on the lesionai skin and then to apply Xanthena® cream only on the left side of affected areas. During the 2-month study period, the use of the corticosteroid cream was resumed in case of flare-up in any side.The results obtained show significant differences of both the total severity score and the intensity of each symptom and sign of AD between the skin areas treated with Xanthena® cream and the control areas (P<0.05); a relevant reduction of steroid requirement was also noted in correlation with the use of this emollient cream (P<0.05). A significant improvement was observed even after the first month of therapy for most symptoms, except for excoriations/fissuring, oozing/crusting and burning which improved only at 2 months. Treatment was well-tolerated by the majority of patients; adverse local reactions, mostly transient and of mild intensity, were observed in 7% of cases.

Abstract
Hormones and growth factors induce in many cell types the production of phosphatidic acid (PA), which has been proposed to play a role as a second messenger. We have previously shown in an acellular system that PA selectively stimulates certain isoforms of type 4 cAMP-phosphodiesterases (PDE4). Here we studied the effect of endogenous PA on PDE activity of transiently transfected MA10 cells overexpressing the PA-sensitive isoform PDE4D3. Cell treatment with inhibitors of PA degradation, including propranolol, induced an accumulation of endogenous PA accompanied by a stimulation of PDE activity and a significant decrease in both cAMP levels and protein kinase A activity. Furthermore, in FRTL5 cells, which natively express PDE4D3, pretreatment with compounds inducing PA accumulation prevented both cAMP increase and cAMP-responsive element-binding protein phosphorylation triggered by thyroid-stimulating hormone. To determine the mechanism of PDE stimulation by PA, endogenous phospholipids were labeled by preincubating MA10 cells overexpressing PDE4D3 with [(32)P]orthophosphate. Immuno- precipitation experiments showed that PA was specifically bound to PDE4D3, supporting the hypothesis that PDE4D3 activation occurs through direct binding of PA to the protein. PA binding site on PDE4D3 was characterized by engineering deletions of selected regions in the N-terminal regulatory domain of the enzyme. Deletion of amino acid residues 31-59 suppressed both PA-activating effect and PA binding, suggesting that this region rich in basic and hydrophobic residues contains the PA binding site. These observations strongly suggest that endogenous PA can modulate cAMP levels in intact cells, through a direct activation of PDE4D3.

Abstract
To determine the properties of the cAMP-specific, rolipram-sensitive phosphodiesterases (cAMP-PDEs) that are expressed in different organs, monoclonal and polyclonal antibodies were raised against different epitopes present in the cAMP-PDE sequences. Of the several antibodies generated against peptides and fusion proteins, one monoclonal and four polyclonal antibodies recognized both the native cAMP-PDEs as well as the denatured proteins on Western immunoblot analysis. An immunoprecipitation assay demonstrated that these antibodies recognized the recombinant rat PDE4A, PDE4B, and PDE4D proteins with different avidity. The polyclonal antibody K118 and the monoclonal M3S1 were most specific for rat PDE4B and PDE4D forms, respectively, whereas the AC55 antiserum displayed the highest affinity for PDE4A forms. This selectivity was confirmed by Western blot analysis using recombinant rat PDE4A, PDE4B, and PDE4D proteins expressed in a heterologous system. These antibodies were used to characterize the cAMP-PDEs expressed in the rat brain. An immunoblot of extract of cortex and cerebellum demonstrated that at least seven different polypeptides specifically cross-reacted with the different antibodies, indicating that multiple cAMP-PDEs are expressed in this tissue. On the basis of cross-reactivity with PDE4D but not PDE4A or PDE4B antibodies, 93- and 105-kDa PDE4D species were detected in the cortex and cerebellum extract. These forms are different from the 68-kDa PDE4D form expressed in endocrine cells after hormonal stimulation. Although the 93-kDa form was recovered in both the soluble and particulate fractions, the 105-kDa polypeptide was mostly particulate in the cortex and cerebellum extracts. PDE4B forms of 90-87 kDa were recovered in both soluble and particulate compartments of the brain extract. These forms were different from the previously identified PDE4A variants of 110 and 75 kDa. These data demonstrate that the presence of multiple cAMP-PDE genes is translated into cAMP-PDE proteins of different sizes and distinct immunological properties and that multiple variants derived from these cAMP-PDE genes are expressed in different regions of the brain and different subcellular compartments. These immunological tools will be useful to identify different cAMP-PDE forms expressed in organs targeted for pharmacological intervention with PDE4 inhibitors.

Abstract
In previous reports we have shown that FSH and beta-adrenergic agonists regulate the levels of mRNA and increase the activity of a high affinity cAMP phosphodiesterase (cAMP-PDE) in the immature rat Sertoli cell in culture. To identify and characterize the hormone-inducible form(s), the cAMP-PDE activity of the Sertoli cell was partially purified and its properties were determined using biochemical and immunological tools. The cAMP-PDE activity present in the 100,000g supernatant of Sertoli cell extracts was purified more than 2000-fold by four HPLC chromatographic steps. The major purified form of cAMP-PDE had a specific activity of 1-2 mumol/(min.mg of protein). Polyacrylamide gel electrophoresis and silver staining analysis showed that a 67-68 kDa polypeptide comigrated with the major peak of cAMP hydrolytic activity. The molecular weight of the crude or purified enzyme determined by gel filtration and sucrose density gradients was 150,000, suggesting that the native enzyme is an oligomeric structure. This PDE hydrolyzed cAMP with a Km of 1.97 +/- 0.26 microM. The hydrolysis of cAMP was neither inhibited nor stimulated by cGMP concentrations lower than 50 microM. Cyclic nucleotide catalysis required Mg2+, but was insensitive to Ca2+. The activity of this form was competitively inhibited by several inhibitors with the following potency: rolipram > RO 20-1724 > methylisobutylxanthine > cilostamide = milrinone. Because mRNAs derived from two distinct PDE4B and PDE4D genes are present in the Sertoli cell, selective and nonselective PDE antibodies were used to determine the origin of the inducible PDE protein.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
The interfacial adsorption properties of polar/apolar inducers of cell differentiation (PAIs) were studied on a mercury electrode. This study, on a clean and reproducible charged surface, unraveled the purely physical interactions among these compounds and the surface, apart from the complexity of the biological membrane. The interfacial behavior of two classical inducers, hexamethylenebisacetamide (HMBA) and dimethylsulfoxide, was compared with that of a typical apolar aliphatic compound, 1-octanol, that has a similar hydrophobic moiety as HMBA but a much smaller dipolar moment. Both HMBA and Octanol adsorb flat in contact with the surface because of hydrophobic forces, with a very similar free energy of adsorption. However, the ratio of polar to apolar moieties in PAIs turned out to be crucial to drive the adsorption maximum toward physiological values of surface charge density, where octanol is desorbed. The electrostatic effects in the interfacial region reflected the adsorption properties: the changes in the potential drop across the interfacial region as a function of the surface charge density, in the physiological range, were opposite in PAIs as compared with apolar aliphatic compounds, as exemplified by octanol. This peculiar electrostatic effect of PAIs has far-reaching relevance for the design of inducers with an adequate therapeutic index to be used in clinical trials.

Abstract
A melanosomal integral membrane glycoprotein of 75 kD (gp75) has been previously identified as the human homologue of the product specified by the murine brown locus. We presently report that this molecule may be susceptible to limited proteolysis and extrinsic radioiodination in intact, live cells. Consequently, it is suggested that its cellular location might include the plasma membrane and/or a cellular compartment easily accessible to proteases and to chemically catalyzed vectorial iodination. This is of interest in view of the potential applicative value of gp75 as a target for the radioimmunoscintography of melanoma lesions.

Abstract
We describe the production and functional characterization of 2 monocytic-cell-lineage-specific immunotoxins constructed with saporin emitoxin (SAP) from Saponaria officinalis. Interest in the production of these immunotoxins, of possible clinical relevance, has been raised by the availability of 2 MAbs of high specificity for circulating monocytes and M5b ANLL, thus envisaging their potential use in bone-marrow purging. SAP emitoxin was selected on the basis of the low cytotoxicity in unconjugated form, as opposed to highly specific cytotoxicity and favourable pharmacokinetical properties in the conjugated form. SPDP conjugation produced immunotoxins which retained serological specificity and protein-synthesis-inhibitory activity. The 2 immunotoxins did not interfere with bone-marrow progenitor-cell growth in a CFU-GM colony assay. On the contrary, they were capable of killing monocytic cells selectively, as demonstrated in phenotypical and functional assays. Thus these 2 novel immunotoxins appear to be promising reagents in purging autologous bone marrow prior to transplantation in patients suffering from monocytic leukaemia.

Abstract
A novel human melanoma specific immunotoxin is described, which has been produced utilizing the murine monoclonal antibody (mAb) Ep2, IgG2a isotype, recognizing an epitope of the glycoprotein/proteoglycan high molecular weight-melanoma associated antigen. mAb Ep2 has been chemically conjugated by a disulphide bond, using the bifunctional reagent SPDP, to the plant toxin Saporin 6 (SAP) extracted from seeds of Saponaria officinalis. Cytotoxicity studies performed in vitro on melanoma cells have shown that Ep2/SAP immunotoxin efficiently kills antigen expressing cells and that its IC50 is approximately 1 x 10(-10) M, while not affecting the viability of antigen-negative melanoma cells at doses as high as 1 x 10(-7) M, therefore indicating a therapeutic index of Ep2/SAP immunotoxin higher than 1000. Kinetic studies have demonstrated that protein synthesis inhibition by Ep2/SAP is rapidly achieved, since a 90% reduction is observed within 3.1 h, and that this inhibitory activity is apparently first order with time. Furthermore, the cytotoxic activity of the immunoconjugate is not dependent, and is not influenced by, the presence in the culture medium of the lysosomotropic agent chloroquine.

Abstract
Employing as immunogen a short-term passaged, highly pigmented human melanoma cell line, we have produced the murine MoAb 2G10 of the IgG1 isotype. The antibody immunoprecipitated from 35S-methionine and 3H-glucosamine metabolically labeled human melanoma cells with a single-chain glycoprotein of 75 kD molecular weight. No such molecule could be precipitated from murine melanomas. To further investigate the fine specificity of the MoAb, immunochemical and immunohistochemical studies were performed. These studies demonstrated that MoAb 2G10 binds a significant fraction of tyrosinase activity from cell lysates, completely immunodepletes soluble cell extract of T4-tyrosinase molecules, and produces immunostaining patterns superimposable on those obtained with anti-T4-tyrosinase antibodies. Thus, MoAb 2G10 appears to recognize a human-specific determinant carried by either T4-tyrosinase or a closely related molecule. The functional relevance of this epitope remains to be evaluated.

Abstract
We have produced and characterized a novel murine monoclonal antibody (LAM7) of IgG1 isotype which appears specific for peripheral blood monocytes (PBM) on the basis of histochemical and functional studies. By indirect immunofluorescence, including FACS analysis, the antibody reacts with 90 +/- 6% of PBM and with monocytic leukemias, while it is totally unreactive with B and T lymphocytes, platelets, granulocytes, peripheral macrophages, dendritic cells, large granular lymphocytes, and nonmonocytic leukemias. The antigen-presenting capacity of peripheral blood mononuclear cells is abolished by treatment with MoAb LAM7 in an antiglobulin-complement-mediated cytotoxicity test, and restored by addition of purified PBM. The progressive disappearance of the antigen recognized by LAM7 from PBM within approximately 3 days in culture, and its absence from both bone marrow precursors and tissue macrophages, define it as a line-specific and stage-specific differentiation.

Abstract
Several immunological abnormalities have been described in Behçet's syndrome, the multisystem disease characterized by the triad of relapsing iridocyclitis with recurrent oral and genital ulcerations. In the present study we have evaluated T cell subsets in the peripheral blood of patients suffering from Behçet's syndrome, using a panel of anti-T cell monoclonal antibodies. When compared with normal subjects, patients with Behçet's syndrome show a discrepancy between the number of T3+ cells and those forming rosettes with sheep erythrocytes, a significantly higher number of T4+ and T8+ double labelled cells, as well as of T6+ lymphocytes in the peripheral blood. The percentage of T8 T lymphocytes is increased, thus lowering the T4+/T8+ cell ratio. The results of this study indicate that a complex imbalance of T cell subsets is present in Behçet's syndrome and give a rationale for possible treatment of these patients with immunomodulators.

Abstract
Varicocele is responsible for a high percentage of impairment of spermatogenesis. In contrast to the normal human testis, Sertoli cell glycogen is reduced, while the reaction product of phosphorylase is considerably increased. Even if the mechanism by which varicocele produces deleterious effects on male fertility remains obscure, an anomaly in glycogen metabolism appears to be present bilaterally in impaired spermatogenesis due to the varicocele.

Abstract
Cyproterone acetate, an antiandrogen drug, is used to reduce mammalian fertility. Effects on the human testis are controversial. Findings in this study reveal that long-term treatment-7 months with 200 mg/day-leads to disappearance of the germinal cells and to Sertoli cells with either a normal or undifferentiated aspect as well as involution of the Leydig cell. Some pathogenetic hypotheses on the action of cyproterone acetate upon human spermatogenesis are discussed.
