Abstract
OBJECTIVE Transit-time flow measurement (TTFM) represents a valid tool in the assessment of the quality of the anastomosis during coronary artery bypass graft (CABG). Nevertheless, a high variability limits its standardized use, lacking univocally accepted cut-off flow values. Our study analyzes TTFM data collected from a study population that underwent off-pump CABG (OP-CABG), with the aim to differentiate into subgroups according to the presence of diabetes mellitus. PATIENTS AND METHODS Patients referred to the Cardiovascular Unit of S. Michele Hospital (Caserta, Italy) for coronary artery disease (CAD) and underwent OP-CABG between January 2015 and December 2019 were enrolled, and intraoperative TTFMs data were recruited and evaluated. Mean graft flow (MGF) and pulsatility index (PI) values were collected and analyzed. RESULTS The study population was composed of 342 patients who underwent OP-CABG with TTFM data regarding 824 grafts. Diabetic patients shared a higher cardiovascular risk profile. The TTFM assessment showed better results for the use of the arterial grafts in diabetic patients, especially for those insulin-dependent; conversely, venous grafts showed worse data with lower MGF and higher PI values. In particular, the anastomoses of the saphenous vein graft with marginal obtuse (MO) coronary artery showed worse MGF results in the insulin-dependent rather than normoglycemic subgroup (28.66 vs. 38.44, p=0.003). CONCLUSIONS Diabetic patients, especially in the insulin-dependent subgroups, have demonstrated lower MGF and higher PI values collected from venous anastomoses with, conversely, inverse results from the arterial one. These results might be correlated to an altered biological adaptability caused by the effects of the diabetic endocrine disorder.

Abstract
In Western countries, calcific aortic valve stenosis (CAS) is widely common, representing the third cause of death among cardiovascular diseases (CVD). The burden of CAS is high, with an increasing prevalence rate related to age. An efficient medical treatment, according to guidelines, lacks to prevent the development and to reduce the progression of CAS. In this context, due to the aging population and the lack of effective medical management, the prevalence is expected to double-triple within the next decades. In our review, we aim to provide an overview of the underlying mechanisms of pathogenesis and the current state of the art regarding pathophysiological insights and novel potential therapeutic targets.

Abstract
OBJECTIVE Hirsutism affects 5-15% of women of reproductive age, with approximately 80% of these women having polycystic ovary syndrome (PCOS). The etiopathogenesis of PCOS remains unclear, the clinical characteristics of PCOS include hyperandrogenism, generally manifested as hirsutism and acne, and both these clinical symptoms are treated with oral contraceptive pills (OCPs), topical medications or antiandrogens. Curcumin (diferuloylmethane) and Plant sterols, such as a phenylpropanoid glycosides of Ajuga reptans, known as Teupolioside, have attracted considerable attention due to their pharmacological properties. Taking into consideration wide-ranging pharmacological and biological properties and the safety of herbal extracts, we proposed a combination of curcumin and teupolioside to evaluate the anti-androgenic properties in women with PCOS and clinical signs of hyperandrogenism. PATIENTS AND METHODS Six hyperandrogenic PCOS women with a hirsutism score (HS) > 20, according to Ferriman-Gallwey scoring system, were involved in the study. These women were treated with a galenical preparation mixture containing curcumin and teupolioside and clinical features were assessed after 12 weeks. RESULTS The nutraceutical combination containing curcumin/teopolioside ameliorated clinical manifestations associated to hyperandrogenism in women with PCOS after a 12-weeks treatment. CONCLUSIONS This pilot study suggests that a curcumin/teopolioside nutraceutical combination is beneficial for improving various clinical manifestations associated to abnormal hormonal parameters in PCOS women, as well as signs and symptoms associated to hyperandrogenism.

Abstract
Introduction Ventricular septal defect (VSD) is one of the mechanical complications of acute myocardial infarction (MI), whose incidence has been decreasing throughout the years because of the emergence of different reperfusion therapy strategies. Methods We present a series of seven patients who underwent surgery for post‐MI VSD repair in our institution in the period between March 2020 and June 2021. Discussion During the recent SARS‐COV2 pandemic, time to hospital admission increased due to patients being overcautious out of fear of exposing themselves to COVID‐19. The increased time to hospital admission, with associated late reperfusion therapy and delayed PCI, is closely related to an augmented incidence of post‐myocardial infarction mechanical complications such as ventricular septal defects. For this reason, we witnessed an increase in the incidence of post‐MI VSD. Conclusion Fear of exposure to SARS‐COV2 in the medical environment was a major source of concern for all our patients. The target of hospital policy should be to reassure patients of freedom from COVID in the emergency department and cardiac wards in order to prevent such dreadful complications.

Abstract
OBJECTIVE Celocentesis is an invasive technique that can provide prenatal diagnosis of single-gene disorders, from as early as 7 weeks' gestation. The objective of this study was to examine the safety of celocentesis. METHODS In this prospective study, celocentesis was performed for prenatal diagnosis of hemoglobinopathy in 402 singleton pregnancies in which both parents were carriers of β-thalassemia or sickle cell disease trait. We assessed procedure-related maternal discomfort or pain, success of sampling and obtaining results, pregnancy outcome and postnatal follow-up. RESULTS First, celocentesis was carried out at a median gestational age of 8.6 (range, 6.9-9.9) weeks and celomic fluid was successfully aspirated in 99.8% of cases. Second, 67% of women had no or only mild discomfort, 18% had moderate discomfort, 12% had mild-to-moderate pain and 3% had severe pain. Third, prenatal diagnosis from analysis of the celomic fluid was successful in 93.8% cases, and in the last 121 cases, it was always successful. Fourth, in all cases of successful sampling and analysis of celomic fluid, the diagnosis was concordant with results obtained from additional prenatal or postnatal testing. Fifth, in addition to diagnosis of hemoglobinopathy, quantitative fluorescence polymerase chain reaction analysis, which was performed to evaluate maternal contamination using several markers for chromosomes X, Y, 21, 18 and 13, led to the accurate diagnosis of chromosomal aneuploidy. Sixth, in all cases of an affected fetus diagnosed by celocentesis in which the parents chose termination of pregnancy, this was carried out < 10 weeks' gestation. Seventh, in 97.1% (298/307) of the continuing pregnancies there was live birth, in seven (2.3%) there was miscarriage and in two (0.7%) there was loss to follow-up. Eighth, fetal abnormalities were diagnosed in three (1%) cases, including unilateral transverse amputation of the forearm, unilateral moderate hydronephrosis and small-bowel duplication. All neonates were examined by a pediatrician and were found to be phenotypically normal, except for the three cases with a prenatally diagnosed defect. CONCLUSIONS Celocentesis can be used for early prenatal diagnosis of genetic abnormalities, and the procedure-related risk of pregnancy complications appears to be low. Copyright © 2020 ISUOG.

Abstract
BACKGROUND AND AIMS Uncovering the main determinants of diet quality is one of the greatest challenges for Public Health, since it could guide future strategies and interventions against cardiovascular diseases (CVDs). The present cross-sectional analysis of the Kardiovize cohort evaluates the prevalence of dietary risk factors for CVDs and their association with social and behavioural characteristics in a random sample of 1536 adults (aged 25-64 years) from Brno, Czech Republic. METHODS AND RESULTS A face-to-face health interview guided by structured questionnaires was carried out on socio-demographic characteristics (age, sex, educational level, employment, marital status, income, and household size) and behaviours (smoking status, physical activity, and sleep habits). Twelve dietary risk factors covered by the Global Burden of Diseases comparative risk assessment framework were assessed using a Food Frequency Questionnaire. In general, we observed that the consumption of nearly all healthy foods and nutrients was suboptimal, and that it was also aggravated by high intake of foods and nutrients that constituted dietary risk factors. Moreover, we found several associations of social and behavioural characteristics with specific dietary risk factors. Particularly, being male (β = 0.466; SE = 0.079; p < 0.001), increasing household size (β = 0.130; SE = 0.047; p = 0.006), low income (β = 0.192; SE = 0.091; p = 0.035), and decreasing physical activity level (β = 0.172; SE = 0.054; p = 0.002) were associated with increasing number of dietary risk factors. CONCLUSION Thus, our study raises an urgent need for Public Health strategies promoting healthy eating in adulthood, which should be based on traditional and novel determinants of dietary risk.

Aim
Different surgical techniques are available for mitral valve (MV) repair in patients with degenerative severe mitral regurgitation (MR). Leaflet resection (LR) and neochordoplasty (NP), both including ring annuloplasty (RA), are the most frequently performed techniques for posterior mitral leaflet prolapse/flail repair. Despite NP technique is supposed to preserve LV physiology more than LR, it is unclear which technique provides the best haemodynamic pattern. In the present study, the results of the two different surgical techniques in terms of left ventricular (LV) dimension and function are investigated.
Methods
23 consecutive patients who underwent MV surgical repair were enrolled. All patients underwent, before surgery and after 8 ± 2 months, 2D and 3D echocardiography with automatic (Heart Model, Philips) assessment of LV volumes and ejection fraction (EF), left atrial (LA) volume, right ventricular (RV) dimension and function, pulmonary artery systolic pressure (PASP), MR, tricuspid regurgitation (TR) and MVPG quantification. MR was corrected using 1) NP with polytetrafluoroethylene sutures and 2) triangular LR, both with RA. Patients were divided in 2 groups according to the surgical technique. Results: techniques were able to successfully correct MR. There were no significant differences in baseline echocardiogram and demographic characteristics between the two groups. There were no significant differences in terms of post-surgical MVPG between the two groups. In all patients a trend in reduction in LV dimension at follow-up was observed, but it was statistically significant only in NP patients (pre-surgical EDV 150 ± 41 VS post-surgical EDV 100 ± 27 ml, p = 0.03).
Conclusions
Both MV repair techniques showed a successful MV repair and an improvement in LV volumes at follow-up, especially in NP group. Further perspective studies are necessary to demonstrate the hypothesis of more physiological haemodynamic pattern associated with NP techniques.

Abstract
Abstract
Background
Comparisons among European populations is useful to identify opportunities for planning nutrition strategies to reduce social inequalities in health. Our study aims to identify dietary patterns in adult women and to evaluate their association with educational level in Czech Republic and Italy, which display different health inequalities.
Methods
We performed a cross-sectional analysis of women (aged 25-64 years) with no history of severe diseases, who have been recruited in Brno (Czech Republic; n = 957) and in Catania (Italy; n = 841). Dietary patterns were derived by Food Frequency Questionnaire and Principal Component Analysis. We tested the association between educational level (low vs. high) and adherence to dietary patterns. Logistic regression models were used to assess Odds ratio (OR) and 95% confidence interval (CI), after adjusting for age, employment status, marital status, smoking status, parity, BMI, and menopause.
Results
In both cohorts, we identified the healthy and the unhealthy dietary patterns. We observed that women with high adherence to the healthy dietary pattern were less educated in Czech Republic, and more educated in Italy. After adjusting for covariates, low educational level was positively associated with adherence to the healthy dietary pattern among Czech women (OR = 2.033; 95%CI=1.301-3.176; p = 0.002), and negatively associated among Italian women (OR = 0.166; 95%CI=0.029-0.952; p = 0.044). No association was identified between educational level and the unhealthy dietary pattern.
Conclusions
In the Italian cohort, findings were consistent with the notion that healthy dietary choices are less common among low-educated groups. By contrast, in newly developed countries such as the Czech Republic, the “nutrition transition” from traditional staples to western foods might be more common in highly-educated groups, probably due to the advocacy of Western culture through mass media and commercial marketing.
Key messages
Low educational level has an opposite effect on healthy diet, exhibiting a positive association in Czech women, and a negative association in Italian women. From a broader perspective, the observed effect of education on diet quality helps explain social health inequalities in Central and Southern Europe.

Abstract
We examined a total of 369 bovine liver and muscle samples for the detection of oxytetracycline (OTC), tetracycline (TC), chlortetracycline (CTC), and doxycycline (DOX) residues by implementation and validation of a LC-MS/MS method. The method showed good recovery values between 86% and 92% at three levels of concentrations. The linearity tests revealed r² > 0.996 for all the tetracyclines examined. Furthermore, the Youden test revealed that the method was robust. Only 14.4% of the samples showed OTC and TC residues in a concentration range of 10.4⁻40.2 µg kg-1. No CTC and DOX residues were found in all the samples analyzed. Liver samples showed the highest average values (31.5 ± 20.6 and 21.8 ± 18.9 for OTC and TC, respectively). The results showed a low incidence of TCs in all the samples examined, in comparison with other studies reported in the literature. A significant decrease in TC residues frequency was found from 2013 (p < 0.05). This work reports for the first time epidemiological data on the presence of TC residues in liver and muscle samples of cattle farmed in Sicily (Southern Italy). The very low incidence of TC residues indicates a continuous improvement in farming techniques in Southern Italy, which is essential to ensure consumers' protection.

Abstract
BACKGROUND AND AIMS The frequency and timing of meals may affect cardiovascular health (CVH) outcomes, but large-scale epidemiological studies are lacking. The aim of this study was to understand the relationship between eating time interval and frequency, and measures of ideal CVH in the Kardiovize Brno cohort study, a random urban sample population in Central Europe. METHODS AND RESULTS 1659 members of the Kardiovize Brno 2030 cohort were included in a cross-sectional study (mean age = 46.86 years; 44.6% male). Exposure variables were eating time interval and frequency, and skipping meals. Primary outcomes were indices of CVH, including body mass index, diet, physical activity, smoking, blood pressure, glucose and cholesterol, and the composite CVH score. Cluster analysis and binary logistic regression analysis were used to evaluate eating habits and the association between variables. After adjustment for well-known risk factors, subjects who skipped breakfast or the afternoon snack had a higher risk of poor CVH (OR = 1.613; 95%CI = 1.121-2.320; p = 0.010; OR = 1.409; 95%CI = 1.110-1.788; p = 0.005, respectively). Moreover, we identified three clusters of individuals based on eating habits; from cluster 1 to cluster 3, eating time interval and frequency increased and this was associated with increases in CVH score from 8.70 (SEM = 0.10) in cluster 1, and 9.06 (SEM = 0.08) in cluster 2 to 9.42 (SEM = 0.09) in cluster 3 (p-trend = 0.019). CONCLUSIONS Our findings suggest that skipping breakfast or the afternoon snack are risk factors for poor CVH, while higher eating time interval and frequency may promote ideal CVH.

Abstract
The affinity of zeolite nanoparticles (diameter of 8-12 nm) possessing high surface area and high pore volume towards human plasma proteins has been investigated. The protein composition (corona) of zeolite nanoparticles has been shown to be more dependent on the plasma protein concentrations and the type of zeolites than zeolite nanoparticles concentration. The number of proteins present in the corona of zeolite nanoparticles at 100% plasma (in vivo state) is less than with 10% plasma exposure. This could be due to a competition between the proteins to occupy the corona of the zeolite nanoparticles. Moreover, a high selective adsorption for apolipoprotein C-III (APOC-III) and fibrinogen on the zeolite nanoparticles at high plasma concentration (100%) was observed. While the zeolite nanoparticles exposed to low plasma concentration (10%) exhibited a high selective adsorption for immunoglobulin gamma (i.e. IGHG1, IGHG2 and IGHG4) proteins. The zeolite nanoparticles can potentially be used for selectively capture of APOC-III in order to reduce the activation of lipoprotein lipase inhibition during hypertriglyceridemia treatment. The zeolite nanoparticles can be adapted to hemophilic patients (hemophilia A (F-VIII deficient) and hemophilia B (F-IX deficient)) with a risk of bleeding, and thus might be potentially used in combination with the existing therapy.

Abstract
BACKGROUND Haemoglobinopathies are a major public health problem in Sicily: it was estimated a frequency of 1/245 couples are at risk of haemoglobinopathies. This paper reviews legislative actions, prevention activities, carrier screening, genetic counselling, foetal sampling and laboratory methodology analysis evolution reporting the results of 30 years of prevention actions to assess the efficiency of our preventative programme in the control of haemoglobinopathies in Sicily. METHODS This programme consisted principally of five phases: legislative actions, public awareness campaign, carrier screening, genetic counselling and prenatal diagnosis. RESULTS These programmes have been very effective, which we can see from a greater public awareness of thalassaemia and its prevention in the target population furthermore by a marked decline in the incidence of thalassaemia major and sickle cell anaemia from 1 in 245 live births in the absence of prevention to 1 in 2000, with a reduction in about 85%. The residual cases were because of a conscious choice by expecting parents in relation to improved life expectancy as well as improved quality of life of the affected patients. CONCLUSION The study suggests that public health authorities should act and invest in a similar programme for prevention of thalassaemia, as well as in relation to the increased survival of patients and the consequent organ complications.

Abstract
INTRODUCTION During an intensive screening program aimed at identifying the healthy carriers of thalassemia and the couples at risk of bearing an affected fetus, a rare single nucleotide variation (SNV), CAP + 1570 T > C (HBB:c*96T > C), located 12 nucleotides upstream of the polyadenylation signal in 3'UTR of the beta globin gene was identified. It was previously reported as a β+ thalassemia mutation and later as a plain polymorphism. METHODS Genotype identification of globin gene mutations was carried out using sequencing analysis, GAP-PCR, and MLPA methods. RESULTS CAP + 1570 T > C (HBB:c*96T > C) was found in 39 heterozygotes, in one case in homozygous state and in thirteen cases of co-inheritance of this nucleotide substitution with other mutations in globin genes. Carriers of this mutation showed a 'silent' phenotype without appreciable microcytosis and hypochromia, so they cannot be differentiated from noncarrier individuals. Compound heterozygotes for this mutation and severe β-thal mutations showed a variable phenotype ranging from β-thal carrier to mild form of β-thalassemia intermedia, revealing new aspects and allowing to better understand the clinical implications of this nucleotide substitution that can be classified as a silent β-thalassemic defect. CONCLUSION Data reported in this study indicate the need of investigating partner of β-thalassemia carrier by complete sequencing analysis of β-globin gene and of providing an appropriate genetic counseling for couples at risk undergoing prenatal diagnosis.

Abstract
BACKGROUND Maternal obesity increases offspring propensity to metabolic dysfunctions and to non-alcoholic fatty liver disease (NAFLD), which may lead to cirrhosis or liver cancer. The circadian clock is a transcriptional/epigenetic molecular machinery synchronising physiological processes to coordinate energy utilisation within a 24-h light/dark period. Alterations in rhythmicity have profound effects on metabolic pathways, which we sought to investigate in offspring with programmed NAFLD. METHODS Mice were fed a standard or an obesogenic diet (OD), before and throughout pregnancy, and during lactation. Offspring were weaned onto standard or an OD at 3 weeks postpartum and housed in 12:12 light/dark conditions. Biochemical and histological indicators of NAFLD and fibrosis, analysis of canonical clock genes with methylation status and locomotor activity were investigated at 6 months. RESULTS We show that maternal obesity interacts with an obesogenic post-weaning diet to promote the development of NAFLD with disruption of canonical metabolic rhythmicity gene expression in the liver. We demonstrate hypermethylation of BMAL-1 (brain and muscle Arnt like-1) and Per2 promoter regions and altered 24-h rhythmicity of hepatic pro-inflammatory and fibrogenic mediators. CONCLUSIONS These data implicate disordered circadian rhythms in NAFLD and suggest that disruption of this system during critical developmental periods may be responsible for the onset of chronic liver disease in adulthood.

Abstract
The deacetylase Sirtuin-1 (Sirt1) is involved in the cardiac hypertrophic responses and cardiac embryo morphogenesis. However, the physiological function of Sirt1 deficiency in the postnatal development of the heart remains to be characterized. The aim of the study was to investigate the relevance of Sirt1 in the development and function of the myocardium. Hearts from Sirt1-deficient mice partially or totally lacking Sirt1 protein activity were analyzed. Loss of Sirt1 activity led to dilated cardiomyopathy in adult hearts, a phenotype accompanied by reduced cardiomyocyte size and the absence of fibrosis. Morphological and functional mitochondrial abnormalities were observed in the adult hearts lacking Sirt1, suggesting that mitochondrial dysfunction contributes to the progression of the observed cardiomyopathy. Moreover, gene expression analyses revealed that mitochondrial genes were the most affected in Sirt1-deficient mice, showing a reduction in their expression. No overt cardiac dilatation was observed in neonates lacking Sirt1 activity, but first signs of mitochondrial alterations were already present. Immunoblot analyses revealed that Sirt1 is highly expressed in the heart after birth, indicating the importance of Sirt1 in the neonatal period. Finally, Sirt1 deficiency affected the acetylation pattern of the myocyte enhancer factor 2 (Mef2) transcription factors, which are critical for normal heart development and mitochondrial integrity. Collectively, our findings indicate that Sirt1 is essential for the maintenance of cardiac mitochondrial integrity and normal postnatal myocardium development.

Abstract
The immune system function oscillates with a 24-hour period driving circadian rhythmicity of immune responses. A circadian timing system comprising central and peripheral oscillators entrains body rhythmicity of physiology and behavior to environmental cues by means of humoral signals and autonomic neural outputs. In every single cell an oscillator goes ticking through a molecular clock operated by transcriptional/translational feedback loops driven by the rhythmic expression of circadian genes. This clock gene machinery steers daily oscillations in the regulation of immune cell activity, driving the periodicity in immune system function. The transcriptional networks that regulate temporal variation in gene expression in immunocompetent cells and tissues respond to diverse physiological clues, addressing well-timed adjustments of transcription and translation processes. Nuclear receptors comprise a unique class of transcriptional regulators that are capable of gauging hormones, metabolites, endobiotics and xenobiotics, linking ligand sensing to transcriptional responses in various cell types through switching between coactivator and corepressor recruitment. The expression of coregulators is highly responsive to physiological signals, and plays an important role in the control of rhythmic patterns of gene expression, optimizing the switch between nycthemeral patterns, and synchronizing circadian rhythmicity with changing physiological demands across the light-dark cycle. The nuclear receptors and transcription factors expressed in the immune components contribute to the cross-talk between the circadian timing system, the clock gene machinery and the immune system, influencing transcriptional activities and directing cell-type specific gene expression programs linked to innate and adaptive immune responses.

Abstract
Alterations in hormone secretion and cytokine levels have been evidenced in many neoplastic diseases. In this study we have evaluated the circadian profile of growth hormone (GH), insulin-like growth factor-1 (IGF-1), interleukin-2 (IL2), melatonin (MEL) and cortisol (COR) serum levels in non-small cell lung cancer patients. Blood was sampled every 4 h for 24 h in 11 healthy (H) men (ages 35-53 years) and 9 men with stage 2, 3 or 4 non-small cell lung cancer (C) (ages 43-63 years). Serum GH, total IGF1, IL2, MEL and COR were measured and examined for group differences, trends, and rhythm characteristics. 24-h means were significantly higher in C234 vs H for GH, GH/IGF1, IL2 and COR, and lower for IGF1, but IL2 and COR were not different for C23 vs H. A linear regression across 4 groups (H, C2, C3, C4) found a positive trend for COR, GH, GH/IGF1 and IL2, and a negative trend for IGF1. A linear regression run between the 24-h mean levels of GH, IGF1, COR, MEL and IL2 in healthy subjects evidenced a statistically significant positive trend between MEL and GH (R = 0.281, p = 0.022) and in cancer patients showed a statistically significant negative trend between GH and IGF1 (R = 0.332, p = 0.01), COR and IGF1 (R=0.430, p=0.001), and a statistically significant positive trend between the 24-h mean of COR and GH (R = 0.304, p = 0.02). Rhythms in MEL and COR (peaks near 01:00h and 08:00h, respectively) indicated identical synchronization to the light-dark cycle for both groups. A circadian rhythm was detected in GH and GH/IGF1 for C23 and H, with IGF1 and IL2 non-rhythmic in any group. In conclusion, an increasing trend and progressive loss of circadian rhythmicity in GH and GH/IGF1, an increasing trend in cortisol and IL2, and a decreasing trend in IGF1 in C, reflect a complex chain of events that could be involved in progression of neoplastic disease. A therapeutic strategy needs to take into account circadian patterns and complex interactions of the multiple functions that characterize the hormone and cytokine levels in the frame cancer progression.

Abstract
BACKGROUND AND PURPOSE mTOR inhibitors are currently used as immunosuppressants in transplanted patients and as promising anti-cancer agents. However, new-onset diabetes is a frequent complication occurring in patients treated with mTOR inhibitors such as rapamycin (Sirolimus). Here, we investigated the mechanisms associated with the diabetogenic effects of chronic Sirolimus administration in rats and in in vitro cell cultures. EXPERIMENTAL APPROACH Sirolimus was administered to rats fed either a standard or high-fat diet for 21 days. Metabolic parameters were measured in vivo and in ex vivo tissues. Insulin sensitivity was assessed by glucose tolerance tests and euglycaemic hyperinsulinaemic clamps. Rapamycin effects on glucose metabolism and insulin signalling were further evaluated in cultured myotubes. KEY RESULTS Sirolimus induced a decrease in food intake and concomitant weight loss. It also induced specific fat mass loss that was independent of changes in food intake. Despite these beneficial effects, Sirolimus-treated rats were glucose intolerant, hyperinsulinaemic and hyperglycaemic, but not hyperlipidaemic. The euglycaemic hyperinsulinaemic clamp measurements showed skeletal muscle is a major site of Sirolimus-induced insulin resistance. At the molecular level, long-term Sirolimus administration attenuated glucose uptake and metabolism in skeletal muscle by preventing full insulin-induced Akt activation and altering the expression and translocation of glucose transporters to the plasma membrane. In rats fed a high-fat diet, these metabolic defects were exacerbated, although Sirolimus-treated animals were protected from diet-induced obesity. CONCLUSIONS AND IMPLICATIONS Taken together, our data demonstrate that the diabetogenic effect of chronic rapamycin administration is due to an impaired insulin action on glucose metabolism in skeletal muscles.

Abstract
Rhythmic oscillations of cellular biological processes are driven by translational-transcriptional feedback loops that realize molecular clocks ticking in every single cell, driven by neural and humoral outputs from the suprachiasmatic nuclei of the hypothalamus that are entrained by environmental photon inputs. The nuclear receptor REV-ERBα has the capability to reset the molecular oscillators of peripheral tissues. The aim of our study was to evaluate the clock gene machinery function in light/dark cycles (LD) and in constant darkness (DD) exploiting in particular the REV-ERBα pattern of expression by using data from two independent experimental settings to reduce procedure related influences. In the LD study C57BL/6 male mice housed on a 12L:12D cycle were sacrificed at 4 h intervals. Liver, kidney, spleen, thymus and testis were harvested and blood was collected. Expression levels of PER1, PER2, CRY1, CRY2, BMAL1, REV-ERBα, CLOCK were evaluated by qRT-PCR. In the DD study Balb/c male mice in the third DD cycle as a continuation of the dark phase of the last LD cycle were sacrificed at 4 h intervals. Lung, heart, liver, stomach, kidney, spleen, and testis were harvested and mRNA expression of PER1, PER2, CRY1, CRY2, BMAL1, REV-ERBα, CLOCK, was evaluated by qRT-PCR. A statistically significant difference was found for the size of the semi-interquartile range of acrophases of clock gene expression in different organs evaluated in LD and DD conditions (4:38∓1:12h versus 1:16∓0:10h, p=0.026). A statistically significant difference was found for the acrophases of clock gene expression in different organs evaluated in LD (p=0.01) and in DD (p<0.0001). In LD study only REV-ERBα showed concomitant expression in the different peripheral tissues with the phase peaking around 07:03∓0.8h. In the DD study all the core clock genes showed concomitant phases in different peripheral mouse tissues and REV-ERB alpha expression peaked around 07:09∓0.9h. In conclusion, REV-ERBα is the only clock gene that maintains its timing of oscillation in the LD study and in the DD study and its phase of expression remains concomitant in the different mouse peripheral tissues in the presence of LD alternance, or in constant darkness. Oscillation in REV-ERBα ligands (heme, carbon monoxide) may affect not only the phase and amplitude of circadian rhythms, but also physiological outputs of the circadian system and REV-ERBalpha may participate in the entrainment of central and peripheral clocks, functioning as a synchronizing hinge of the clock gene machinery.

Abstract
Molecular clocks drive circadian rhythmicity of cellular functions in peripheral tissues and organs, kidney included, whereas in the testis this clockwork seems constitutively active. We have evaluated the periodicity and the dynamics of expression of the clock genes BMAL1, CLOCK, PER1, PER2, CRY1, CRY2 and REV ERBalpha over 24 h in the kidney and testis using a mouse model. The periodicity was explored by single cosinor, and dynamics were explored by calculation of fractional variations of gene expression related to time intervals. Kidney and testis were harvested at 4-h intervals over a 24-h period from eight-week-old C57BL/6 male mice housed individually on a 12 h light (L)-dark (D) cycle (lights on at 08:00 h; lights off at 20:00 h) and mRNA was extracted and analyzed by Quantitative Real-time Reverse Transcription PCR. A statistically significant difference was evidenced between kidney and testis for the original values of expression level of BMAL1, PER1, PER2 CRY1, CRY2 and REV ERBα. A statistically significant difference was evidenced between kidney and testis for the fractional variation of BMAL1, PER2, CRY1, CRY2 and REV ERBα. A significant 24-h rhythmic component was found for BMAL1, CLOCK, PER1, PER2, CRY1, CRY2 and REV ERBα in the kidney, whereas no core clock gene showed circadian rhythmicity in the testis. Fractional variations provided significant circadian rhythms for BMAL1, PER2, CRY, CRY2 and REV ERBα in the kidney, whereas in the testis the fractional variation calculations showed no circadian rhythmicity, but quantitative comparison showed statistically significant differences in only 16.7 percent of the time points studied. In conclusion, in the kidney the clock gene machinery shows circadian oscillation of mRNA levels and time-related variations in the rate of change of clock gene expression. In the testis the clock genes do not show circadian rhythmicity of expression and the dynamics of variation are not characterized by a periodical pattern, but are quantitatively similar to those observed in the kidney. These data suggest that in the testis the clock gene machinery shows a tissue-specific pattern of function and clock genes may play a different role in the testis with regard to other peripheral tissues, maybe in relation to the presence of developmental and differentiation phenomena.

Abstract
Immune parameters show rhythmic changes with a 24-h periodicity driven by an internal circadian timing system that relies on clock genes (CGs). CGs form interlocked transcription-translation feedback loops to generate and maintain 24-h mRNA and protein oscillations. In this study we evaluate and compare the profiles and the dynamics of variation of CG expression in peripheral blood, and two lymphoid tissues of mice. Expression levels of seven recognized key CGs (mBmall, mClock, mPer1, mPer2, mCry1, mCry2, and Rev-erbα) were evaluated by quantitative RT- PCR in spleen, thymus and peripheral blood of C57BL/6 male mice housed on a 12-h light (L)-dark (D) cycle and sacrificed every 4 h for 24 h (3–4 mice/time point). We found a statistically significant time-effect in spleen (S), thymus (T) and blood (B) for the original values of expression level of mBmal1 (S), mClock (T, B), mPer1 (S, B), mPer2 (S), mCry1 (S), mCry2 (B) and mRev-Erbα (S, T, B) and for the fractional variation calculated between single time-point expression value of mBmal1 (B), mPer2 (T), mCry2 (B) and mRev-Erbα (S). A significant 24-h rhythm was validated for five CGs in blood (mClock, mPer1, mPer2, mCry2, mRev-Erbα), for four CGs in the spleen (mBmal1, mPer1, mPer2, mRev-Erbα), and for three CGs in the thymus (mClock, mPer2, mRev-Erbα). The original values of acrophases for mBmal1, mClock, mPer1, mPer2, mCry1 and mCry2 were very similar for spleen and thymus and advanced by several hours for peripheral blood compared to the lymphoid tissues, whereas the phases of mRev-Erbα were coincident for all three tissues. In conclusion, central and peripheral lymphoid tissues in the mouse show different sequences of activation of clock gene expression compared to peripheral blood. These differences may underlie the compartmental pattern of web functioning in the immune system.

Abstract
AIMS/HYPOTHESIS Glitazones are powerful insulin sensitisers prescribed for the treatment of type 2 diabetes. Their use is, however, associated with fluid retention and an increased risk of congestive heart failure. We previously demonstrated that pioglitazone increases proximal sodium reabsorption in healthy volunteers. This study examines the effects of pioglitazone on renal sodium handling in individuals prone to insulin resistance, i.e. those with diabetes and/or hypertension. METHODS In this double-blind randomised placebo-controlled four-way crossover study, we examined the effects of pioglitazone (45 mg daily during 6 weeks) or placebo on renal, systemic and hormonal responses to changes in sodium intake in 16 individuals, eight with type 2 diabetes and eight with hypertension. RESULTS Pioglitazone was associated with a rapid increase in body weight and an increase in diurnal proximal sodium reabsorption, without any change in renal haemodynamics or in the modulation of the renin-angiotensin aldosterone system to changes in salt intake. A compensatory increase in brain natriuretic peptide levels was observed. In spite of sodium retention, pioglitazone dissociated the blood-pressure response to salt and abolished salt sensitivity in salt-sensitive individuals. CONCLUSIONS/INTERPRETATION Pioglitazone increases diurnal proximal sodium retention in diabetic and hypertensive individuals. These effects cause fluid retention and may contribute to the increased incidence of congestive heart failure with glitazones.

Abstract
Monoclonal gammopathies (GM) are divided into clinically manifest and asymptomatic syndromes. In the last 20 years, the prevalence of GM in industrialized Countries is more than doubled. In order to verify the prevalence of these forms in Western Sicily, at University General Hospital of Palermo an epidemiologic inquiry was made to check the presence of GM as fortuitous event during routine analyses; from March 2000 to March 2001 it was found a prevalence of 0.89% (196 cases on 22100 analysed). Average age was 67.5, with 58.2% men and 41.8% women from different Departments of University General Hospital. The finding of a monoclonal component must be considered an important laboratory datum to observe with time by not invasive laboratory examinations (high-resolution serum-protein electrophoresis and immunofixation).

Abstract
Our group, thanks to the considerable help offered by prof. S. Fujimoto, Chief of the Immunologic Oncology Department of the Kochi Medical School (Japan), developed a method of "in vitro" activation of cytotoxic T lymphocytes (CTL), which are directed against tumour-specific antigens MHC-linked of the tumor cells. A protocol of specific immunotherapy based on the use of the CTL cells appropriately manipulated as therapeutic agents is our goal. The protocol recognizes five essential points: 1) retrieve and culture of tumor cells; 2) retrieve of T Lymphocytes; 3) induction of CTL cells; 4) assay of CTL activity; 5) reinfusion of the activated CTL cells to the patient.

Abstract
The loop of Henle (LOH) reabsorbs approximately 15% of filtered HCO3- via a luminal Na(+)-H+ exchanger and H+ATPase. During acute metabolic alkalosis (AMA) induced by i.v. HCO3- infusion, we have observed previously inhibition of LOH net HCO3- reabsorption (JHCO3-), which contributes to urinary elimination of the HCO3- load and correction of the systemic alkalosis. To determine whether the activities of the Na(+)-H+ exchanger and/or H(+)-ATPase are reduced during AMA, two inhibitors believed to be sufficiently specific for each transporter were delivered by in vivo LOH microperfusion during AMA. AMA reduced LOH JHCO3- from 205.0 +/- 10.8 to 96.2 +/- 11.8 pmol.min-1 (P < 0.001). Luminal perfusion with bafilomycin A1 (10(-4) mol.l-1) caused a further reduction in JHCO3- by 83% and ethylisopropylamiloride (EIPA; 5.10(-4) mol.l-1) completely abolished net HCO3- reabsorption. The combination of bafilomycin A1 and EIPA in the luminal perfusate was additive, resulting in net HCO3- secretion (-66.6 +/- 20.8 pmol.min-1; P < 0.001) and abolished net fluid reabsorption (from 5.0 +/- 0.6 during AMA to 0.2 +/- 1.1 nl.min-1; P < 0.001). To establish whether HCO3- secretion via luminal stilbene-sensitive transport mechanism participates in LOH adaptation to AMA, we added diisothiocyanato-2,2'-stilbenedisulphonate (DIDS; 10(-4) mol.l-1) to the perfusate. No effect was found.(ABSTRACT TRUNCATED AT 250 WORDS)
