Abstract
An increased carotid intima-media thickness (IMT) is detectable in young subjects with parental history of premature myocardial infarction (PHPMI) or hypertension (PHH). In this study we evaluated if PHPMI and PHH exert a different influence on carotid IMT and if their conjunction produces additive effects. High-resolution B-mode ultrasonographic evaluation of common carotid artery IMT was acquired from 48 subjects without PHPMI and PHH (22 males, 26 females; mean age 22.1±4.9 years; controls), 24 age- (±1 year) and sex-matched subjects with PHH without PHPMI (PHH-positive/PHPMI-negative subjects), 24 age- and sex-matched subjects with PHPMI without PHH (PHH-negative/PHPMI-positive subjects) and 24 age- and sex-matched subjects with both PHPMI and PHH (PHH/PHPMI-positive subjects). Lipid profile, resting blood pressure, smoking behaviour and body mass index (BMI) were also assessed. Carotid IMT was smaller in controls (0.41±0.07mm) compared to PHH-positive/PHPMI-negative subjects (0.47±0.10, p=0.023), to PHH-negative/PHPMI-positive subjects (0.54±0.11, p<0.001) and to PHH/PHPMI-positive subjects (0.52±0.10mm, p<0.001). Carotid IMT was greater in PHH-negative/PHPMI-positive (p=0.006) and in PHH/PHPMI-positive (p=0.031) than in PHH-positive/PHPMI-negative subjects. No difference in carotid IMT was evident between PHH-negative/PHPMI-positive and PHH/PHPMI-positive subjects (p=0.549). In the comparison among subjects using multiple regression analysis, only PHPMI, age and BMI were independently associated with carotid IMT. In healthy young subjects with PHPMI and/or PHH, carotid IMT is increased. PHPMI is a stronger predictor of increased carotid IMT than PHH. PHH in conjunction with PHPMI does not add any further detrimental effect on carotid IMT.

Abstract
AIM Contrast-induced nephropathy (CIN) is most commonly defined as acute renal failure occurring within 48-72 h of exposure to intravascular radiographic contrast medium that is not attributable to other causes. In international literature a 25% increase in serum creatinine levels or an increase in absolute values of 0.5 mg/dL from baseline has been suggested to define CIN. The reported incidence of CIN varies widely, ranging from 2% to 50%. This variability results from differences in the presence or absence of risk factors. With a retrospective analysis authors evaluated the use of NaCl saline hydration and N-acetyl cysteine (NAC) to prevent CIN in different populations of patients at high and low risk undergoing coronary artery angiography. METHODS From January 2007 to December 2008, 597 patients underwent coronary artery angiography with a low osmolarity contrast agent. Nephrotoxic drugs such as diuretics, metformin, ACE-I and ARBs were stopped at least 24 h before the procedure. The population was divided into two groups: group A (high risk 342 patients, 57.2%) identified for the presence of at least one risk factor such as diabetes, age >65 years, baseline creatinine >1.4 mg/dL and group B (low risk 255 patients, 42.8%) for the absence of any of the risk mentioned above. Only group A was treated with a saline hydration (1 mL/kg/h) plus NAC 600 mg 12 h before and 12 h after the procedure. RESULTS The overall incidence of CIN was 6.7% (40 patients). In particular, the incidence of CIN was 4.4% (15 patients) in the group A and 9.8% (25 patients) in the group B respectively (P=0.017). Interestingly, the Contrast Index (volume administrated/theoretical maximum volume) was significantly lower in group B (P<0.005). In the multivariate analysis, including risk factors such as age, diabetes, hypertension, hypercholesterol-mia, current smoke, baseline creatinine level, Contrast Index and hydration, the last variable was the only one inversely correlated independently with the incidence of CIN (P=0.001). CONCLUSIONS The hydration with saline and NAC is an effective and low-cost tool in preventing CIN in patients undergoing coronary artery angiography and, according to the current guidelines, should be used in all high-risk patients. Present results show that even in patients at low risk for CIN, hydration could be useful: in fact, despite the Contrast Index was significantly lower in this population, the incidence of CIN was greater, thus suggesting a potential role for hydration also in the low-risk population.

Abstract
The synthesis of "naked" ellagitannin analogues 1 and 2, having a preferred sense of twist of the diphenyl moiety, with a rhamnose and a glucose template, is reported. A clear induction in the chirality of the diphenyl moiety, mediated through a 10-membered ring via ester linkages, was observed. The chiral scaffold of glucose (diequatorial 2,3-hydroxyl groups) exerts a remarkable stronger atropdiastereoselective effect onto the diphenoyl group than the rhamnose ring (axial-equatorial 2,3-hydroxyl groups), according to the Schmidt-Haslam hypothesis.

Abstract
[formula: see text] This letter describes the reduction to practice of a novel concept for functionalization of the anomeric carbon of carbohydrates with a nitrogen substituent. Thus, bisheterodienes with a thiono sulfur terminus and a sulfonylimine terminus are shown to undergo cycloaddition smoothly and stereoselectively to three different glycals.

Abstract
OBJECTIVES To investigate the effect of low doses of the angiotensin converting enzyme inhibitor enalapril on renal haemodynamics and albuminuria in normotensive and hypertensive type 1 (insulin-dependent) diabetic patients with incipient or overt nephropathy. METHODS Twenty-two type 1 (insulin-dependent) diabetic patients with persistent microalbuminuria or macroalbuminuria and normal serum creatinine were studied. Of all patients, 16 males and 6 females, age 45 +/- 13 years, diabetes duration 19 +/- 11 years, insulin dose 38 +/- 11 U/day, 10 were normotensive and 12 were hypertensive. After 3 months of run-in period the patients were assigned to treatment with 5 mg or 10 mg enalapril based on the presence of normotension or hypertension respectively. Before and after 6 months of treatment, renal function was assessed by evaluation of glomerular filtration rate (99m Tc-DTPA), renal plasma flow (131-I iodohippurate), filtration fraction and renal vascular resistance. Mean arterial pressure, albumin excretion rate, urinary urea excretion and glycated haemoglobin were also determined. RESULTS Administration of enalapril resulted in both groups of patients in a significant fall in mean arterial pressure, albumin excretion rate, glomerular filtration rate, filtration fraction, and renal vascular resistance. Decreasing albumin excretion did not correlate with a drop in systemic blood pressure or filtration fraction. No significant variations were observed in renal plasma flow, in urinary urea excretion or in glycated haemoglobin. CONCLUSIONS Our results suggest that low doses of enalapril are effective in influencing renal haemodynamics and reducing urinary albumin excretion in both normotensive and hypertensive type 1 (insulin-dependent) diabetic patients with incipient or overt nephropathy. The lowering effect of the angiotensin converting enzyme inhibitor on albuminuria seems to be independent of the action on systemic blood pressure and renal haemodynamic changes.
