Mitochondrial DNA (mtDNA) is characterized by high variability, maternal inheritance, and absence of recombination. Studies of human populations have revealed ancestral associated polymorphisms whose combination defines groups of mtDNA types (haplogroups) that are currently used to reconstruct human evolution lineages. We used such inherited mtDNA markers(More)
High prevalence and low female/male ratio for validated centenarians are observed in Sardinia and these findings appear to be thus far unique to this island. Moreover a specific region on the island is characterized by exceptional male longevity. We calculated the extreme longevity index (ELI), defined as the percentage of persons born in Sardinia between(More)
Although heparin-induced thrombocytopenia (HIT) is a known complication of intravenous unfractionated heparin (UFH), its incidence in medical patients treated with subcutaneous UFH is less well defined. To determine the incidence of HIT in this category of patients, the platelet count was performed at baseline and then every 3 +/- 1 days in 598 consecutive(More)
The possibility that four loci (REN, THO, PARP, SOD2) are associated with longevity was explored by comparing the genotypic pools of subjects older than 100 years with those of younger subjects matched for sex and geographic area (northern and southern Italy). The markers (all located within the respective gene) were HUMREN4; HUMTHO1; HUMPARP (gt)845nt;(More)
The efficacy of the heparin-induced extracorporeal LDL-precipitation (HELP)-apheresis procedure has been studied in an open prospective multicentre trial. After 2 years of regular weekly HELP-treatment the data from 39 of 51 patients could be evaluated according to the study criteria. Twelve of the initially recruited study patients were omitted from the(More)
The results of plasma lipid and lipoprotein analysis in two related patients, brother (R.U.) and sister (R.R.) with analbuminemia, and three first-degree relatives (parents and sister) are reported. Both patients showed a remarkable increase in cholesterol and phospholipid levels, and there was a corresponding increase in serum apo B and apo A-I. This(More)
BACKGROUND AND AIMS Human longevity seems to be directly correlated with optimal functioning of the immune system, suggesting that some genetic determinants of longevity reside in those polymorphisms for the immune system genes which regulate immune-inflammatory responses, in particular cytokine gene polymorphisms. The frequency of -174C single nucleotide(More)
The effect of diet enriched with a monounsaturated fatty acid (olive oil) on serum lipoproteins, biliary cholesterol saturation index, and gallbladder motility compared with a standard low-fat diet was evaluated in 11 young volunteers admitted to a metabolic ward. A significant decrease of mean total cholesterol (-9.5%), total apo B (-7.4%), LDL cholesterol(More)
This paper describes an epidemiological study performed in all centenarians living in Sardinia, a large island located in the Mediterranean sea, 120 Km from the Italian coast. Due to its long-standing isolation, low immigration rate, high endogamy and rather uniform lifestyle, Sardinia offers an ideal setting in which to study the genetic traits associated(More)
BACKGROUND In this study, the apolipoprotein E (apoE) genotypes as well as plasma lipid and lipoprotein levels have been determined for the first time in 633 healthy and unrelated inhabitants on the island of Sardinia (291 men and 342 women, age range 6-89 years), randomly selected in the four districts of Sardinia among healthy people having parents and(More)
