Abstract
Aims
Immune endothelial inflammation, underlie coronary heart disease (CHD) related phenotypes, could provide new insight into the pathobiology of the disease. We investigated DNA methylation level of the unique CpG island of HLA-G gene in CHD patients and evaluated the correlation with cardiac computed tomography angiography (CCTA) features.
Methods
Thirty-two patients that underwent CCTA for suspected CHD were enrolled for this study. Obstructive CHD group included fourteen patients, in which there was a stenosis greater than or equal to 50% in one or more of the major coronary arteries detected; whereas subjects with Calcium (Ca) Score=0, uninjured coronaries and with no obstructive CHD were considered as control subjects (Ctrls) (n=18). For both groups, DNA methylation profile of the whole 5'UTR-CpG island of HLA-G was measured. The plasma soluble HLA-G (sHLA-G) levels were detected in all subjects by specific ELISA assay. Statistical analysis was performed using R software.
Results
For the first time, our study reported that 1) a significant hypomethylation characterized three specific fragments (B, C and F) of the 5'UTR-CpG island (p=0.05) of HLA-G gene in CHD patients compared to Ctrl group; 2) hypomethylation level of one specific fragment positively correlated with coronary Ca score, a relevant parameter of CCTA (p<0.05) between two groups.
Conclusions
Our results showed that reduced levels of circulating HLA-G molecules could derive from epigenetic marks inducing hypomethylation of specific regions into 5'UTR-CpG island of HLA-G gene in CHD patients with obstructive coronary stenosis vs non critical stenosis group.

Abstract
BACKGROUND The development of alloantibodies may complicate the management of patients with β-thalassemia. An extended antigenic matching may reduce the risk of alloimmunization. Our previous study showed that the introduction of molecular red blood cell (RBC) typing allows finding suitable blood units for multi-transfused patients. The aim of this study was to evaluate the benefit of RBC transfusion with extended antigenic match. MATERIALS AND METHODS At the University of Campania "L. Vanvitelli", we selected β-thalassemia major patients (age ≤23 years), without preformed alloantibodies. Data of patients receiving transfusion of leukoreduced RBC units for a period of one year with partial better match (PBM) including ABO, RhD, C/c, E/e, K/k antigens and consecutive one year with extended match (EM) including ABO, RhD, C/c, E/e, K/k, Fya/Fyb, Jka/Jkb, M/N, S/s antigens, were compared. RESULTS Eighteen patients, 8 males and 10 females with a mean age of 15.4 years (6.4 SD) received a mean number of 41.2 (6.0 SD) RBC units transfused with PBM and 41.8 (6.2 SD) with EM protocols. After two years of RBC transfusions with both antigen matching protocols, no new alloantibodies were developed in patients. No significant differences in Hb concentration and volume of RBC transfused were found between PBM and EM protocols. CONCLUSIONS Thalassemia patients may benefit from receiving RBC transfusions based on extended antigen matching as demonstrated by the lack of new alloantibodies. However, our data show a high concordance between PBM and EM protocols considering pre-transfusion Hb, increment of Hb and volume of RBC transfused.

Abstract
Neuroendocrine bladder cancer is extremely rare, with an estimated incidence of 0.5%- 0.7%. In bladder cancers there is no evident connection between the neuroendocrine phenotypic expression and the clinical history. However, prognosis is usually poor and the survival rate at 5 years does not exceed 8%, if untreated. Methods. We are here describing three case reports of bladder carcinoma with neuroendocrine differentiation, which is extremely aggressive and leads rapidly to death. At the present time, the local control of these tumors is achieved by radical cystectomy and radiotherapy; they can be both associated to chemotherapy. However, since these lesions are fairly rare, there is no gold standard therapy and there are no prospective studies on the management of these tumors. Conclusions. Considering the quick evolution and progression of any variant of the neuroendocrine tumors of the bladder, urologists and anesthetists should see them as real oncological emergencies. A prompt intervention through radical surgery with cystectomy and linfadenectomia, and the anathomo-pathologist's systematic investigation of the scraps could make the approach therapeutic and not only palliative. Prospective studies on neo-adjuvant chemotherapy as well as experimental studies about target therapies may yield new guidelines on the tumor management.

Abstract
BACKGROUND Vitamin D exerts pleiotropic effects and few studies are available in the Italian population. AIM Aim of our study was to evaluate vitamin D status in children living in Northern Italy. METHODS We studied vitamin D levels in a population of 113 normal weight (NW) and 444 obese (OB) children, prepubertal and pubertal. We considered vitamin D levels >20 ng/ml as normal, but also measured percentage of children with vitamin D levels higher than a cutoff of 30 ng/ml. RESULTS 68.2 % of NW children showed normal levels of vitamin D, while 31.8 % showed a clear vitamin D deficiency. Only 28.3 % showed vitamin D levels higher than 30 ng/ml. Obese children showed 55.6 % of subjects with normal levels of vitamin D and 44.4 % of subjects a status of vitamin D deficiency. Only the 18.9 % showed vitamin D levels higher than 30 ng/ml. Mean vitamin D levels in NW children (27.3 ± 1.2 ng/ml) were higher than in OB children (21.8 ± 0.6 ng/ml). No differences have been found between prepubertal and pubertal children in terms of vitamin D levels. CONCLUSIONS Our paediatric population demonstrates a low percentage of vitamin D sufficiency. In particular, obese children show only 19 % of subjects with normal levels while almost half of this population shows a clear deficiency. Further studies are needed to support these results and to evaluate the possible metabolic consequences.

Abstract
Aim. Sulfhydryl angiotensin-converting enzyme (ACE) inhibitors exert antiatherosclerotic effects in preclinical models and antioxidant effects in patients. However, whether ACE inhibitors have any clinically significant antiatherogenic effects remains still debated. Objectives. In mildly hypertensive patients, we evaluated the effect of the sulfhydryl ACE inhibitor zofenopril in comparison with the carboxylic ACE inhibitor enalapril on carotid atherosclerosis (intima-media thickness [IMT] and vascular lumen diameter) and systemic oxidative stress (nitrite/nitrate, asymmetrical dimethyl-L-arginine, and isoprostanes). Material and methods. In 2001, we started a small prospective randomized clinical trial on 48 newly diagnosed mildly hypertensive patients with no additional risk factors for atherosclerosis (eg, hyperlipidemia, smoke habit, familiar history of atherosclerosisrelated diseases or diabetes). Patients were randomly assigned either to the enalapril (20 mg/d, n = 24) or the zofenopril group (30 mg/d, n = 24); the planned duration of the trial was 5 years. Carotid IMT and vascular lumen diameter were determined by ultrasonography for all patients at baseline and at 1, 3, and 5 years. Furthermore, nitrite/nitrate, asymmetrical dimethyl-L-arginine, and isoprostane levels were measured. Results. In our conditions, IMT of the right and left common carotid arteries was similar at baseline in both groups (P = NS). Intima-media thickness measurements until 5 years revealed a significant reduction in the zofenopril group but not in the enalapril group (P b .05 vs enalapril-treated group). This effect was coupled with a favorable nitric oxide/oxidative stress profile in the zofenopril group. Conclusion. Long-term treatment with the sulfhydryl ACE inhibitor zofenopril besides its blood pressure–lowering effects may slow the progression of IMT of the carotid artery in newly diagnosed mildly hypertensive patients.

Abstract
Experimental models have enhanced our understanding of atherothrombosis pathophysiology and have played a major role in the search for adequate therapeutic interventions. Various animal models have been developed to simulate thrombosis and to study in vivo parameters related to hemodynamics and rheology that lead to thrombogenesis. Although no model completely mimics the human condition, much can be learned from existing models about specific biologic processes in disease causation and therapeutic intervention. In general, large animals such as pigs and monkeys have been better suited to study atherosclerosis and arterial and venous thrombosis than smaller species such as rats, rabbits, and dogs. On the other hand, mouse models of arterial and venous thrombosis have attracted increasing interest over the past two decades, owing to direct availability of a growing number of genetically modified mice, improved technical feasibility, standardization of new models of local thrombosis, and low maintenance costs. To simulate rupture of an atherosclerotic plaque, models of arterial thrombosis often involve vascular injury, which can be achieved by several means. There is no animal model that is sufficiently tall, that can mimic the ability of humans to walk upright, and that possesses the calf muscle pump that plays an important role in human venous hemodynamics. A number of spontaneous or genetically engineered animals with overexpression or deletion of various elements in the coagulation, platelet, and fibrinolysis pathways are now available. These animal models can replicate important aspects of thrombosis in humans, and provide a valuable resource in the development of novel concepts of disease mechanisms in human patients.

Abstract
OBJECTIVE Maternal hypercholesterolaemia during pregnancy increases lipid peroxidation in mothers and fetuses and programs increased susceptibility to atherosclerosis later in life. The objective of this study was to elucidate the role of the placenta in mediating oxidative stress from mother to offspring. DESIGN Comparison between normo- and hypercholesterolaemic mothers (n = 36 each) and their children. SETTING Obstetric wards, hospitals of the University of Naples and Regione Campania. POPULATION Healthy primiparas delivering by caesarean section. METHODS Biochemical measurements of oxidative stress and serum leptin in cord plasma and placenta, immunochemistry of placenta microvessels, and vasoreactivity studies were performed. MAIN OUTCOME MEASURES Oxidative status (i.e. lipid composition and content of oxidised fatty acids, activity of pro- and antioxidant enzymes, immunohistochemical presence of oxidation-specific epitopes) in maternal and cord blood and in placental tissue, as well as vascular reactivity in omental arteries. RESULTS Hypercholesterolaemia during pregnancy was associated with extensive changes in fatty acid composition of both maternal and cord blood lipids, sufficient to alter vasoreactivity of omental vessels. Results also indicated that the placenta is not only subject to substantial oxidative stress, but that it may further increase fetal oxidative stress through changes of pro- and antioxidant enzyme activities. CONCLUSIONS The placenta plays an important role in both transmitting and enhancing pathogenic effects of gestational hypercholesterolaemia.

Abstract
The effects of diets of low caloric value on rats used in aging studies were investigated. Groups of 85 Sprague-Dawley rats were fed ad libitum from 3 months of age on three different diets containing 8 or 10 Megajoule (MJ) of metabolizable energy and 80 or 100 g of crude protein/kg. Body weights, food consumption, and morphological and biochemical parameters were monitored throughout life. Kidneys were examined histologically. Rats given the diet with highest energy and protein ate less food, attained greater weights, and had larger abdominal fat deposits than those on the lower energy diets. They had a raised proteinuria, and nearly half developed glomerulosclerosis and tubulo-interstitial damage by 26 months. There was no significant difference in mortality between the groups, and no other serious abnormalities were observed. It is concluded that rats can be maintained into old age with no signs of nutritional inadequacy on diets with lower energy and protein contents than those in general use.

Abstract
In Watanabe heritable hyperlipidemic (WHHL) rabbits, hypercholesterolemia and hypertriglyceridemia develop from birth, because of a deficiency of low-density lipoprotein receptors, and are followed by a consequent early development of aortic atherosclerosis. This closely resembles human familial hypercholesterolemia. Starting in 1984, we have developed a closed colony by breeding two male and two female homozygous WHHL rabbits, obtained from Japan (Dr. Watanabe, Kobe University). In our facility, the application of a selective breeding program, strictly based on mating parents that both have high serum lipid concentrations, has produced markedly elevated cholesterol (701 +/- 172 mg/dl, mean +/- SD) and triglyceride (780 +/- 325 mg/dl) concentrations in weaning rabbits. Clinical chemical analysis revealed no kidney or liver function abnormalities even in animals with extremely high lipid concentrations, and hematologic profiles were very similar in WHHL and age-matched New Zealand White rabbits, with the exception of platelet count, which was significantly higher in WHHL rabbits. Platelet aggregation induced by collagen and platelet-activating factor was significantly reduced in WHHL rabbits, whereas thrombin and prothrombin times appeared normal when compared with those in New Zealand White rabbits.

Abstract
The effects of five 0.3 mg/kg intravenous administrations of vincristine (VCR) at weekly intervals were studied in the rabbit. Body weight gain was impaired starting from the first injection, while gross signs of motor paralysis and hair loss initiated from the third week. At the end of the observation period blood analysis revealed normocytic normochromic anemia, elevated serum creatine kinase, and low serum alkaline phosphatase, whereas all the tested parameters related to liver and kidney functions where within normal limits. The decreased number of red blood cells was the consequence of a complete, although reversible, blockade of staminal hematopoietic activity. Two important indexes of peripheral nerve function were clearly altered at the end of the treatment: (i) the sciatic nerve conduction velocity in vitro was 27% reduced and (ii) the latency between sciatic nerve stimulation and extensor digitorum longus (EDL) twitch in vivo was 34% prolonged. The usefulness of the rabbit as an animal model to study side-effects of VCR treatment is discussed.
