Abstract
Abstract
Background
The accuracy of the 2014 ESC model to predict 30-day mortality in hemodynamically stable patients with acute pulmonary embolism (PE) is relatively limited.
Purpose
The aims of this study in hemodynamically stable patients with acute PE were i) to evaluate the prognostic value of a novel respiratory index (RI) (oxygen saturation in air to respiratory rate ratio) and ii) to assess the accuracy of the RI-model (simplified Pulmonary Embolism Severity Index [sPESI] + RI), both in predicting 30-day mortality.
Methods
A collaborative database of hemodynamically stable patients with PE was divided into two cohorts (derivation and validation) with equal numbers of patients, based on a temporal criterion. Study outcome was 30-day all-cause-death. Discrimination and calibration were assessed in the derivation and validation cohorts by the c-statistics and by the Hosmer-Lemeshow test, respectively.
Results
30-day all-cause-death occurred in 7.5% of the 319 patients in the derivation cohort (mean age 72 years, females 53%). The RI was an independent predictor of 30-day mortality (p=0.004). A RI ≤3.8 was associated with an increased death rate compared to higher RI values (15.4% vs 5.0%, OR 3.4, 95% CI 1.5–8.1). When the RI≤3.8 was integrated in the sPESI, the novel RI-model showed a good discriminatory power (c-statistics 0.703, 95% CI 0.603–0.803).
In the 319 patients of the validation cohort (30-day mortality 6.9%, mean age 71 years, females 55%) the discriminatory power of the RI-model was confirmed (c-statistics 0.838, 95% CI 0.768–0.907).
The RI-model and the 2014 ESC model had a c-statistics of 0.772 (95% CI 0.709–0.834) and of 0.687 (95% CI 0.620–0.753) in the overall population, respectively.
Conclusion
In this study, the RI independently predicted 30-day mortality in hemodynamically stable patients with acute PE. A clinical model including RI showed a better discriminatory value than 2014 ESC model and could be used for risk stratification in these patients.

Abstract
Essentials In acute pulmonary embolism (PE), risk stratification is essential to drive clinical management. Improving the 2014-ESC risk stratification strategy is crucial in hemodynamically stable patients. Oxygen saturation and respiratory rate improve risk stratification in hemodynamically stable PE. Simple and routine tests improve risk stratification of hemodynamically stable PE. SUMMARY: Background In patients with acute pulmonary embolism (PE), risk stratification for short-term death is recommended to drive clinical management. A risk stratification strategy combining the simplified Pulmonary Embolism Severity Index (PESI), echocardiography and troponin was proposed by the European Society of Cardiology (ESC) in 2014. The identification of hemodynamically stable patients at increased risk of death by this strategy needs improvement. Objective To assess whether further stratification by serial cut-off values of oxygen saturation or respiratory rate improves the accuracy of the ESC risk stratification strategy in hemodynamically stable PE patients. Methods Prospective cohorts of hemodynamically stable patients with PE were merged in a collaborative database. The accuracy of risk stratification for 30-day mortality by the original and a modified 2014 ESC strategy was assessed. Results Overall, 255 patients (27%) were categorized as low, 510 (54%) as intermediate-low and 181 (19%) as intermediate-high risk according to the original 2014 ESC strategy. Thirty-day mortality was 1.2% in low, 10% in intermediate-low and 11% in intermediate-high-risk patients. By adding oxygen saturation in air of < 88%, the discriminatory power of the 2014 ESC model improved for 30-day mortality (c-statistics, 0.71; 95% confidence interval [CI], 0.65-0.77 vs. 0.63, 95% CI, 0.56-0.69) and for PE-related death (c-statistics, 0.75; 95% CI, 0.69-0.81 vs. 0.63, 95% CI 0.56-0.69). Conclusions Simple and routine tests, such as oxygen saturation or respiratory rate, could be added to the 2014 ESC strategy for risk stratification to identify hemodynamically stable PE patients at increased risk of death who are potentially candidates for more aggressive treatment.

Abstract
BACKGROUND Bariatric surgery (BS) is known to favorably impact fasting lipid profile. Fasting and postprandial lipids were evaluated before and 2 years after BS in obese type 2 diabetic (T2DM) patients. METHODS A prospective study was conducted in 19 obese T2DM patients: ten undergoing sleeve gastrectomy (SG) and nine undergoing Roux-en-Y gastric bypass (RYGB). Before and 2 years after BS, clinical parameters and the response of lipid and incretin hormones to a mixed meal (MM) were assessed. RESULTS The two groups had similar characteristics at baseline. After BS, weight loss was similar in the two groups (p ≤ 0.01). Fasting glucose, insulin, and triglycerides decreased while HDL cholesterol increased in a similar way (p < 0.05); in contrast, fasting LDL cholesterol decreased only after RYGB (p < 0.05). Post-meal glucose concentrations decreased while early insulin response significantly improved after both procedures (p < 0.001 for both). Postprandial triglycerides decreased after both procedures (p < 0.05) while postprandial LDL cholesterol decreased only after RYGB (p < 0.05). Meal-GLP-1 increased postoperatively in both groups although to a greater extent after RYGB (p < 0.001 vs. SG). GIP decreased after both procedures, especially after RYGB (p = 0.003). At multivariate analysis, GLP-1 peak was the best predictor of LDL reduction (β = -0.552, p = 0.039) while the improvement of HOMA-IR (β = 0.574, p = 0.014) and weight loss (β = 0.418, p = 0.036) predicted triglycerides reduction. CONCLUSIONS Both surgical procedures markedly reduce fasting and postprandial triglycerides and increase HDL cholesterol levels. LDL cholesterol decreases only after RYGB through a mechanism likely mediated by the restoration of GLP-1.

Abstract
BACKGROUND AND AIM To evaluate glycemic variability (GV) and oxidative stress in patients who achieved type 2 diabetes (T2DM) remission after bariatric surgery (BS). METHODS AND RESULTS Twenty-two patients (M/F10/12, age 50 ± 9 years, BMI 31 ± 6 kg/m2) who were in remission of T2DM (T2DM remitters) after BS since at least 1 year and 22 age-, sex- and BMI-matched control subjects were studied. Of the BS group, eleven subjects had undergone Roux-en-Y gastric bypass (RYGB) and eleven subjects sleeve gastrectomy (SG). Oral glucose tolerance test (OGTT), 7 days-continuous glucose monitoring, 24-h urinary excretion of 8-isoprostaglandin F2α (8-isoPGF2α) and dietary intake evaluation were performed. According to general linear model for repeated measures, glucose and insulin response during OGTT were significantly different in T2DM remitter than in control subjects (p < 0.001, for both). All measures of GV (standard deviation, coefficient of variation and mean amplitude of glucose excursions) were significantly higher in T2DM remitters than in controls, (p < 0.001 for all). These indexes were higher among RYGB than SG patients (p < 0.05). The time spent out of the 60-160 mg/dl range was significantly longer in T2DM remitters undergoing RYGB than in controls (p < 0.02). Mean 24-h urinary 8-isoPGF2α excretion was significantly higher in T2DM remitters than that of control subjects (p = 0.04). All GV indexes were directly correlated with blood glucose levels at 30 and 60 min during OGTT (p < 0.05-0.001). CONCLUSION Remission of T2DM after BS is characterized by high GV and high oxidative stress in the face of fasting blood glucose and HbA1c within the normal range.

Abstract
The aim of the work was to compare the hormonal and the metabolic mechanisms involved in weight loss and remission of T2DM one year after Roux-en-Y gastric bypass (RYGB) and vertical sleeve gastrectomy (VSG) in morbidly obese type 2 diabetic (T2DM) patients. Insulin sensitivity, insulin secretion, and the gastrointestinal (GI) hormone response to a mixed meal test (MMT) were evaluated before and one year after BS (14 RYGB and 19 VSG). RYGB and VSG groups had similar characteristics at baseline. Weight loss at one year was similar in the 2 groups (ΔBMI%: - 32±10 and - 30±7%, p=0.546). Insulin sensitivity and insulin secretion improved similarly after either procedures with a similar rate in T2DM remission (86% in RYGB and 76% in VSG). Meal-stimulated GLP-1 levels increased after both procedures reaching significantly higher levels after RYGB (p=0.0001). GIP response to MMT decreased to a similar extent after the 2 interventions (p=0.977). Both fasting and post-meal ghrelin concentrations were markedly suppressed after VSG and significantly lower than RYGB (p=0.013 to p=0.035). The improvement of insulin sensitivity and beta-cell function was significantly associated with weight loss (p=0.014 to p=0.035), while no relation was found with the changes in GI hormones. In conclusion, in morbidly obese T2DM patients, RYGB and VSG result in similar improvements of the glucose status in the face of different GI hormonal pattern. Weight loss is the key determinant of diabetes remission one year after surgery.

Abstract
Subjects carrying the T2238C ANP gene variant have a higher risk to suffer a stroke or myocardial infarction. The mechanisms through which T2238C/αANP exerts detrimental vascular effects need to be fully clarified. In the present work we aimed at exploring the impact of C2238/αANP (mutant form) on atherosclerosis-related pathways. As a first step, an atherosclerosis gene expression macroarray analysis was performed in vascular smooth muscle cells (VSMCs) exposed to either T2238/αANP (wild type) or C2238/αANP. The major finding was that apolipoprotein E (ApoE) gene expression was significantly downregulated by C2238/αANP and it was upregulated by T2238/αANP. We subsequently found that C2238/αANP induces ApoE downregulation through type C natriuretic peptide receptor (NPR-C)-dependent mechanisms involving the upregulation of miR199a-3p and miR199a-5p and the downregulation of DNAJA4. In fact, NPR-C knockdown rescued ApoE level. Upregulation of miR199a by NPR-C was mediated by a reactive oxygen species-dependent increase of the early growth response protein-1 (Egr-1) transcription factor. In fact, Egr-1 knockdown abolished the impact of C2238/αANP on ApoE and miR199a. Of note, downregulation of ApoE by C2238/αANP was associated with a significant increase in inflammation, apoptosis and necrosis that was completely rescued by the exogenous administration of recombinant ApoE. In conclusion, our study dissected a novel mechanism of vascular damage exerted by C2238/αANP that is mediated by ApoE downregulation. We provide the first demonstration that C2238/αANP downregulates ApoE in VSMCs through NPR-C-dependent activation of Egr-1 and the consequent upregulation of miR199a. Restoring ApoE levels could represent a potential therapeutic strategy to counteract the harmful effects of C2238/αANP.

Abstract
AIMS To evaluate the clinical efficacy of bariatric surgery vs medical therapy with liraglutide on weight loss, glycemic control and cardiovascular risk profile in patients with type 2 diabetes and severe obesity. METHODS A retrospective evaluation was conducted in 31 patients with type 2 diabetes and severe obesity who had undergone bariatric surgery and in 31 patients with type 2 diabetes and comparable body weight who had added liraglutide to their background medical treatment in the period 2009-2013. Anthropometric parameters, glycemic control, treatment of diabetes and other comorbidities, safety and side effects before and 12 months after treatment were assessed. RESULTS Age was 47 ± 8 years (mean ± SD) in bariatric surgery and 56 ± 9 years in medical treatment group (p < 0.001); body mass index before treatment was 44 ± 7 and 40 ± 4 kg/m(2) in bariatric surgery and medical treatment, respectively (p = 0.03). Twelve months after treatment, average weight loss was 38 ± 15 kg among bariatric surgery patients, and 5 ± 8 kg in medical treatment group (p < 0.001). Glycemic control improved in both groups with greater improvement in bariatric surgery patients. The UKPDS risk score decreased in both groups, although it remained higher in medical treatment than in bariatric surgery patients (p < 0.001). Of note, almost 60 % of patients on liraglutide met the target of glycated hemoglobin <7 % (53 mmol/mol) and lost ≥5 % of body weight. CONCLUSIONS In severely obese type 2 diabetic patients, bariatric surgery reduced body weight and improved overall metabolic control to a greater extent than medical treatment. Randomized clinical studies are necessary.

Abstract
BACKGROUND Bariatric surgery (BS) is able to positively influence fasting lipid profile in obese type 2 diabetic patients (T2DM), but no data is available on the impact of BS on postprandial lipid metabolism neither on its relation with incretin hormones. We evaluated the short-term (2 weeks) effects of BS on fasting and postprandial lipid metabolism in obese T2DM patients and the contribution of changes in active GLP-1. METHODS We studied 25 obese T2DM patients (age = 46 ± 8 years, BMI = 44 ± 7 kg/m2), of which 15 underwent sleeve gastrectomy and 10 underwent gastric bypass. Lipid and incretin hormone concentrations were evaluated for 3 h after ingestion of a liquid meal before and 2 weeks after BS. RESULTS After BS, there was a significant reduction in body weight (p < 0.001), fasting plasma glucose (p < 0.001), fasting plasma insulin (p < 0.05), HOMA-IR (p < 0.001), and fasting plasma lipids (p < 0.05). The meal response of plasma triglycerides, total cholesterol, and HDL cholesterol was significantly lower compared to pre-intervention (p < 0.05, p < 0.001). In particular, the incremental area under the curve (IAUC) of plasma triglycerides decreased by 60% (p < 0.005). The meal-stimulated response of active GLP-1 increased, reaching a statistical significance (p < 0.001). CONCLUSIONS BS leads to an early improvement of fasting and postprandial lipemia. The fall in fasting triglycerides is associated with an improvement of insulin resistance, while the reduction of postprandial lipemia is likely related to reduced intestinal lipid absorption consequent to bariatric surgery.

Abstract
AIM Human leucocyte antigen (HLA) system plays an essential role in the human immune system activity and the expression of some specific HLA antigens could modify the immune response to vaccinations. Celiac disease is included among the diseases associated to specific HLA profiles, principally characterized by the expression of the HLA DQ2 antigen. METHODS Our study was a retrospective study, leaded on a group of celiac children, with the object to evaluate their immunological response to both obligatory and recommended vaccinations in childhood. It was a retrospective study, including 66 patients affected by celiac disease, between 3 and 15 years of age, and a control group of 50 children of the same age. All patients performed both obligatory and recommended vaccinations as indicated in the Italian standard regimen for vaccinations. The immunologic response to each vaccine was analysed and compared in the two groups. Moreover, authors also studied the immunologic response to vaccines in celiac children comparing patients whose diagnosis was made before 18 months of age with those whose disease was diagnosed after 18 months of age. RESULTS Our results showed that in celiac patients the immunological response to vaccine is similar to that one found in general population, except for HBV vaccine. CONCLUSION The evaluation of immunological response to HBV vaccine should be regularly effectuated in celiac children and revaccination should be recommended.

Abstract
This study was undertaken to assess medium-term effects of laparoscopic sleeve gastrectomy (LSG) on body weight and glucose homeostasis in severely obese type 2 diabetic (T2DM) subjects. Twenty-five obese T2DM subjects (10 M/15 F, age 45 ± 9 years, BMI 48 ± 8 kg/m(2), M ± SD) underwent evaluation of anthropometric/clinical parameters and glucose homeostasis before, 3 and 9-15 months after LSG. Mean BMI decreased from 48 ± 8 kg/m(2) to 40 ± 9 kg/m(2) (P < .001) at 3 months and 34 ± 6 kg/m(2) (P < .001) at 9-15 months after surgery. Remission of T2DM (fasting plasma glucose < 126 mg/dL and HbA1c < 6.5% in the absence of hypoglycemic treatment) occurred in all patients but one. There was a remarkable reduction in the percentage of patients requiring antihypertensive and hypolipidemic drugs. Our study shows that LSG is effective in producing a significant and sustained weight loss and improving glucose homeostasis in severely obese T2DM patients.

Abstract
In previous work dealing with the identification of four sleep sequences (SS-->W, SS-->PS, SS-->TS-->W and SS-->TS-->PS) in the baseline session of adult male Wistar rats [Mandile P, Vescia S, Montagnese P, Romano F, Giuditta A. Characterization of transition sleep episodes in baseline EEG recordings of adults rats, Physiol Behav 1996;60:1435-1439], we have shown that those containing an intervening episode of transition sleep (TS) strongly correlate with the number of avoidances scored the following day [Vescia S, Mandile P, Montagnese P, Romano F, Cataldo G, Cotugno M, Giuditta A. Baseline transition sleep and associated sleep episodes are related to the learning ability of rats, Physiol Behav 1996;60:1513-152]. More recently, clusters of sleep sequences (trains) separated by waking intervals longer than 60 s have been identified in the baseline session of the same rats [Piscopo S, Mandile P, Montagnese P, Cotugno M, Giuditta A, Vescia S. Identification of trains of sleep sequences in adult rats, Behav Brain Res, this volume], and distinguished in homogeneous or mixed trains according to the presence of a single sleep sequence or more than one sequence. Mixed trains have been further separated into trains containing the SS-->TS-->W sequence (+TSW trains) and trains lacking it (-TSW trains). Analysis of the distribution of variables of baseline trains (and of their sleep sequences and components) among fast learning (FL), slow learning (SL), or non-learning (NL) rats, indicates that variables of +TSW trains prevail in FL rats, while variables of -TSW trains prevail in NL rats. In addition, variables of +TSW trains correlate with the number of avoidances of the training session, while variables of -TSW trains do not significantly correlate, or show inverse correlations. Interestingly, sleep sequences such as SS-->W or SS-->TS-->W show direct or inverse correlations with avoidances depending on whether they are included in +TSW trains or in -TSW trains. The data are interpreted to suggest that the outcome of brain operations performed during a sleep sequence may selectively condition the appearance of later sequences within a time interval shorter than a given threshold. An analogous mechanism may be responsible for the aggregation of sleep components in sleep sequences.

Abstract
In previous studies based on high resolution EEG analyses of the 7 h baseline session of 18 adult male Wistar rats [6,14], we have identified four sleep sequences initiating with slow wave sleep (SS) and terminating with waking (W) or paradoxical sleep (PS). Two of these sequences contained an intervening episode of transition sleep (TS). Several variables of these sequences (SS-->W, SS-->TS-->W, SS-->TS-->PS, and SS-->PS) were selectively correlated with the capacity of rats to learn a two-way active avoidance task the following day, and were differently distributed in fast learning, slow learning and non learning rats [21]. The temporal organization of different sleep components in sequences suggested that a comparable temporal organization might concern the different sleep sequences, albeit on a longer time scale. We have now used waking periods longer than 60 s to separate clusters of baseline sleep sequences (trains) in the same rats. Trains containing the same sleep sequence (homogeneous trains) have been distinguished from trains containing different sleep sequences (mixed trains). In addition, mixed trains including the SS-->TS-->W sequence (+TSW trains) have been separated from mixed trains lacking that sequence (-TSW trains). Mixed trains of the +TSW type were longest and most numerous, while homogeneous trains were shortest and least abundant. Mixed trains of the -TSW type displayed intermediate values. Several variables of sleep sequences and sleep components differed within mixed trains and among mixed and homogeneous trains. The data indicate that baseline sleep sequences aggregate in relatively long strings in a non random fashion. The mechanism of this association is discussed.

Abstract
High resolution computerized EEG analyses, and behavioral observations were used to identify slow wave sleep (SS), paradoxical sleep (PS) and transition sleep (TS) in adult male Wistar rats exposed to a session of two-way active avoidance training. Of the four sleep sequences that could be identified, two included TS (SS-->TS-->W and SS-->TS-->PS), while the other two did not (SS-->W and SS-->PS). Comparison of post-trial sleep variables between fast learning rats (FL, reaching criterion in the training session), slow learning rats (SL, reaching criterion in the retention session the following day), and non learning rats (NL, failing to reach criterion) indicated that the total amounts of SS, TS and PS of the SS-->TS-->PS sequence was markedly higher in FL rats than in SL rats. In addition, in comparison with the corresponding baseline period, the average duration and total amount of SS and TS episodes of the SS-->TS-->PS sequence increased in FL rats, while the number of SS-->TS-->W sequences decreased. On the other hand, the average duration of SS episodes increased in the SS-->TS-->W and SS-->W sequences of SL rats, and in the SS-->W and SS-->TS-->PS sequences of NL rats. Correlative analyses between number of avoidances and post-trial sleep variables demonstrated that avoidances were directly correlated with the duration of SS episodes of the SS-->TS-->PS sequence and with the duration of TS episodes of the SS-->TS-->W sequence, but inversely correlated with the number and amount of SS episodes of the SS-->W sequence and with the duration and amount of SS episodes of the SS-->PS sequence. On the whole, the data supported the view that TS-containing sleep sequences are involved in long-term storage of novel adaptive behavior, while sleep sequences lacking TS are involved in the maintenance of innate behavioral responses.

Abstract
The EEGs of 18 adult male Wistar rats were recorded during a baseline session lasting 7 h (day 1). The following day, rats were trained for a 2-way active avoidance task in an automated shuttle-box. A retention test was scheduled on the third day. On the basis of the number of avoidances scored during the training and retention sessions, rats were assigned to a fast-learning group (FL; achieving criterion during the training session), a slow-learning group (SL; achieving criterion in the retention test session), and a nonlearning group (NL; failing to achieve criterion). Vigilance states were determined by analyzing EEG data in 5-s epochs and calculating EEG power spectra of consecutive time intervals as short as 1 s. This high-resolution method led to the identification of transition sleep episodes that followed slow-wave sleep (SS) and were followed by waking (TS-->W) or by paradoxical sleep (TS-->PS). Comparison of the baseline sleep variables of the 3 behavioral groups revealed the presence of several significant differences. These observations were confirmed by the results of correlative analyses between baseline sleep variables and number of avoidances scored during the training and retention sessions. The most reliable indices of the capacity to learn the avoidance task were the amounts of SS preceding the TS-->W or the TS-->PS sequence, and the amounts of either component of the latter sequence. These variables displayed markedly higher values in FL rats. In addition, the amount of SS preceding TS-->W and the amount of TS-->(W) were significantly correlated with the number of avoidances scored during the training session. On the other hand, 1' SS-->(PS) and (SS)-->PS episodes were longer in NL rats than in SL or FL rats, respectively; and 2, the duration of SS-->(PS) episodes was inversely correlated with the number of avoidances of the first training period. The data are interpreted to suggest that TS and associated sleep episodes may predict the acquisition of the avoidance task, and the episodes of SS-->PS not associated with TS may predict the retention of innate responses, such as freezings or escapes.

Abstract
We describe a method of implanting a telemetric transmitter of EEG signals in the laboratory rat. The transmitter is available commercially and may be implanted in a subcutaneous pocket prepared in the hindermost dorsal region of the animal. The two stainless steel electrodes connected to the transmitter are led to the cranium through a subcutaneous tunnel, and are fixed to the cranium bones. EEG signals are collected by a receiver placed under the cage; reception of the signals is improved by suitably placed antennae. The method allows recording of EEG data from a free-moving rat during the expression of behavioral tasks in a limited space.

Abstract
In addition to modulatory roles concerning bodily functions, sleep is assumed to play a main processing role with regard to newly acquired neural information. Elaboration of memory traces acquired during the waking period is assumed to require two sequential steps taking place during slow wave sleep (SWS) and eventually during paradoxical sleep (PS). This view is suggested by several considerations, not the least of which concerns the natural sequence of appearance of SWS and PS in the adult animal. While the involvement of PS in memory processing is well documented, the involvement of SWS is supported by the results of baseline and post-trial EEG analyses carried out in rats trained for a two-way active avoidance task or a spatial habituation task. Together with control analyses, these data indicate that the marked increase in the average duration of post-trial SWS episodes does not reflect the outcome of non-specific contingent factors, such as sleep loss or stress, but is related to memory processing events. Several considerations have furthermore led to the proposal that, during SWS, after a preliminary selection step, the first processing operation consists in the weakening of non-adaptative memory traces. The remaining memory traces would then be stored again under a better configuration during the ensuing PS episode. This view is in agreement with several relevant features of sleep, including the EEG waveforms prevailing during SWS and PS, as well as the ontogenetic sequence of appearance of SWS and PS. Some theoretical considerations on the role of sleep are also in agreement with the sequential hypothesis. More recent data indicate that the learning capacity of rats is correlated with several baseline EEG features of sleep and wakefulness. They include the average duration of PS episodes and of SWS episodes followed by wakefulness (longer in fast learning rats), and the waking EEG power spectrum of fast learning rats whose output is more balanced in the frequency range below 10 Hz than in slow learning and in non-learning rats. Additional EEG data suggest that fast learning rats may accomplish 'on line' processing of newly acquired information according to a sequence of events not dissimilar from the one proposed by the sequential hypothesis.

Abstract
The antibody responses of Maldivian infants early in their life to simultaneous immunization against hepatitis B virus, poliomyelitis, diphtheria and tetanus were investigated. The vaccines were given at 6, 10 and 14 weeks of age. Among 243 newborn babies from HBsAg-negative mothers, 103 received three doses of oral poliomyelitis (OPV) and diphtheria and tetanus (DTV) vaccines; 105 were similarly immunized but received in addition the recombinant hepatitis B vaccine (HBV); 35 were immunized with the HBV recombinant vaccine alone. The antibody response to all of the vaccines was effective. No significant differences among the groups were observed. Hepatitis B vaccination of infants neither affected nor was affected by the contemporary administration of OPV and DTV vaccines.

Abstract
A vaccination cycle cannot always be completed with the same type of vaccine with which it was initiated because the same type of vaccine is not always available at the vaccination centers. For this reason we have verified the possibility of substituting one of two anti hepatitis B DNA-recombinant vaccines [Engerix B (SK&F); Recombivax HB (MSD)] both available in Italy in the vaccination protocol. A study was performed on 480 subjects using both types of DNA recombinant vaccine and on 160 using only one type of vaccine. Our data show that there is no difference in immunogenic potency of the two DNA recombinant vaccines available in Italy and that a cycle begun with one vaccine can be completed with the other with no effect on the percentage of seroconversion or the mean anti-HBs titre.

Abstract
27 healthy babies born to HBsAg, antiHBs and antiHBc negative mothers were given three doses of hepatitis B vaccine "Recombivax HB" (5 micrograms/dose/0.5 ml) at 3, 5 and 11 months of age (Piazza's protocol). AntiHBs response was highly satisfactory. Since both in terms of seroconversion rate and of mean antiHBs titre immunogenicity of other hepatitis B vaccines given at 3, 5 and 11 months of age was already demonstrated, it is possible to conclude that Piazza's protocol is valid for all hepatitis B vaccines available in Italy and will certainly facilitate the compulsory hepatitis B vaccination in infants in Italy.

Abstract
Following the demonstration of a fully satisfactory immunogenic activity of a hepatitis B vaccination protocol consisting of three doses of Hevac B Pasteur vaccine given at 3,5 and 11 months of age, it was possible to administer this vaccine at the same times as the vaccinations for diphtheria, tetanus and polio which are mandatory in Italy at those ages. We have also shown that both another plasma-derived vaccine, H-B-VAX (MSD), as well as the DNA-recombinant Engerix B (SK&F) are highly immunogenic when given at the same times as the mandatory childhood vaccinations. In this paper we demonstrate that the same schedule can be used for another hepatitis B vaccine prepared by a DNA-recombinant technique, Recombivax HB (MSD) recently introduced in Italy. In fact two doses of this vaccine, the first given at three months of age and the second two months later, resulted in a 100% seroconversion rate and a mean anti-HBs titre of 440 mUI/ml. Although the date are incomplete since the third dose will be given at 11 months of age, we conclude that this hepatitis B vaccine can also be used in the mass vaccination campaigns of infants in Italy, the first of which was initiated in January 1987 in an hyperendemic area near Naples (HBsAg prevalence about 14%). We underline that this mass vaccination campaign is the first in Europe.

Abstract
A case of primary adenocarcinoma of the duodenum associated with Recklinghausen's disease and Caroli's disease provides the opportunity to review the literature. Malignant tumours of the duodenum are extremely rare and even rarer is their association with R's and Caroli's diseases. It should not be forgotten that in Recklinghausen's disease gastro-intestinal involvement is possible. Caroli's disease is diagnosed anatomopathologically. Surgical resection remains the sole satisfactory treatment when the tumour has not spread locally or at a distance. If it has, treatment must be palliative.

Abstract
A classic case of Ménétrier's disease in an adult male, diagnosed by histological examination of operative biopsy is reported. Stress is laid on the clinical aspects of the disease and on the histological aspects of that particular type of hyperplastic gastropathy that underlies it. Brief mention is also made of the states of pseudohyperplastic gastropathy that may represent a source of diagnostic confusion, particularly from the radiological viewpoint.

Abstract
We report in this paper that proteins from the surface of ejaculated spermatozoa contain antigenic determinants cross-reacting with a rabbit antiserum raised against native CFS, a protein secreted from the rat seminal vesicle and composed of two subunits, namely RSV IV and RSV V. Conversely, no such proteins could be extracted from cauda epididymal spermatozoa. The cross-reacting proteins derived from the ejaculated spermatozoa were analyzed by SDS-PAGE. An electrophoretic pattern different than that expected for native CFS in denaturing conditions was found. In vitro reconstitution experiments showed that labeled native CFS is able to bind cauda epididymal spermatozoa. The CFS protein recovered from the sperm surface was examined and alterations of its structure were also noted. The sperm-coating abilities of CFS and of its RSV IV subunit are discussed.

Abstract
The Authors assuming as hypothesis that elements beyond Calcium could be included as carbonate according to crystalline structure of Aragonite and Calcite in the shell of Mytilus g. have verified the selective inclusion of Cr, Mg, Zn, Fe, Cu, Cd, Pb in the biocrystals in relation to their ionic radius. Though the ratio of concentrations of these elements in the shell layers: [Me] calcite/[Me] aragonite ( [C]/[A] ) is significatively greater than 1 for Zn and Mg, significatively less than 1 for Cr and Pb and the no-significative distribution of Cu, Fe, Cd do not allow a sure relationship between the ionic radii of Ca and the investigated elements in the process of shell inclusions. However, authors, do not exclude that these elements may be included differently from the relative aragonitic or calcitic crystalline carbonate structures.

Abstract
The Authors investigated on the relations between the amount of Heavy Metals (Me) and free aminoacids (FAA) from tissues of Mytilus galloprovincialis. Similar mussels were collected from three sampling zones of bay of Naples. The analyzed Me were Cr+3, Cd+2, Pb+2. The obtained results show that behaviour of Me and FAA is similar. These data suggested to the Authors that FAA changes have to be related to an attempt to recover their's equilibrium more than a direct influence of Me on mussel's FAA metabolism.

Abstract
The size frequency distribution, the shell weight, the semilogarythmic growth, the carbonic anhydrase activity has been investigated between two populations of mussels from different sampling zones. Significative differences were found in the parameters investigated between the two populations. The authors conclude that the reason of this morphological and biochemical differences may arise from different natural hydrobiological factors and/or from different pollution of their habitat.

Abstract
The Authors have investigated the structural property of organic shell matrix from Mytilus galloprovincialis by scanning microscopy. The microscopic investigation shows differences between matrix from nacreous layer or argonite and matrix from outer layer or calcite. The first shows a "cavernous" surface; the other instead shows a "smooth" surface. The Authors conclude that probably these differences may influence the different crystallographic arrangement of biocrystals.

Abstract
The amounts of Fe, Zn, Cu, Mg were determined in the inner and outer layers of shells of Mytilus g.. Different values significatively between the layers were found only for Mg. The ratio [Me]Calcite/ [Me]Aragonite was calculated and it is not more than one, for all the colonies of different sampling zones. The Authors conclude that perhaps the reason of this behaviour is the different pollution of their habitat.

Abstract
Purification methods of vegetable extracts have been experienced during our researches on the possible presence of the aromatic polycyclic hydrocarbons (particularly 3,4 benzopyrene) in vegetables. The validity of different methods has been determined by IR spectrophotometric analysis using special apparatus (IR-DATA-STATION). Vegetables extracts have been purified efficaciously by column chromatography, saponification and special methods (Grimmer's method). The described method eliminates, nearly entirely, the polluting substances that could alternate the chemical analysis of the vegetable extracts.

Abstract
Within the sphere of the researches the biological effects of the most common edible oils (peanuts, sunflower, maize, soya and rectified olive) it has been studied the interaction between the development of the Euglena gracilis unicellular seaweed and the presence of the unsaponifiables examined in their cultures. As a biologically active substance it has been used 3,4-benzopyrene. Spectrophotometric analysis have evidenced that all the unsaponifiables, especially those of the soya seeds, caused a growth decrease of the seaweed culture. A similar effect is found in the cultures treated with aromatic hydrocarbon.

Abstract
During the research concerning biological effects of the most common edible oils (peanuts, sunflower, maize, soya and rectified olive), the Authors have tested the insaponificable fractions on the calf kidney cellular monosurface. The insaponificable of the maize seeds oil determine a net decrease of the speed growth. It has also been noted a very slight increase of the cells development, in the cultures treated with the insaponificables of some other oils, compared with the samples of those not treated. As comparison substance it has been used 3,4 benzpyrene, because his toxic action on the cells is well known.

Abstract
The writers within the context of the research on the biological actions of the unsaponificables in the most common edible oils, have tested the effects produced by such unsaponificables on the culture of E. Coli. The unsaponificables, and those of seed oils of peanuts and sunflowers in particular, aid the doubling of the E. Coli. Similar research on the culture of animal cells (in vitro) and unicellular algae, are at present outstanding.

Abstract
By inserting near the under-axillary gland of the rats Wistar (one month age) compressed material containing g. 0.250 of non-saponificable sunflower seeds oil, it has been noted an increase of the number of the mitosis in the under-axillary gland, in the lung and some mitosis in the liver. Such results are similar to those obtainable by administering, with similar method 0.050 g. of 3,4benzopyrene or 0.100 g. of the hydrocarbon oxidization products. The histological analysis have been effected on the organs of rats sacrificed one month after inoculation.

Abstract
The cristallographic analysis of the valve of Mytilus galloprovincialis using the scansion microscopy method shows probable inclusions of Cd and Zn in the carbonate calcite layer and probable inclusions of Pb in carbonate aragonite layer. This confirms the supposition of a substitution of Ca ions from heavy metals investigated and the formation of the respective carbonates that precipitate together with calcium carbonate in the process of growth of the valve of the mollusc examined.
