Description of Lifestyle, Including Social Life, Diet and Physical Activity, of People ≥90 years Living in Ikaria, a Longevity Blue Zone
A cross-sectional observational study was conducted to describe the lifestyle of people ≥90 years, living in Evdilos or Raches, two municipalities of the Greek island of Ikaria, classified a longevity blue zone. The 71 participants were interviewed and underwent the Mediterranean Islands study food frequency questionnaire (MEDIS-FFQ) and the international physical activity questionnaire (IPAQ). The frequency of social contacts was daily for 77.9% of participants, weekly for 16.1%, and monthly for 5.9%. Most participants (90.0%) believed in God, and 81.4% took part in religious events. A total of 62.0% attended Panigiria festivals. Access to primary health care was considered difficult in th…
Longevity hotspot in Sicily. The exploration of a new possible blu zone
We are conducting a survey in some mountainous Sicilian populations, particularly in villages sited in the Palermo province, part of the Madonie Park. To ascertain the true longevity rate, we checked the born and death registers, analyzing about 37,000 newborns between 1881 and 1917 in a sample of five small municipalities located in Madonie. About 1,700 individuals died at the age of 90 years and over, and about one hundred were centenarians. Therefore, the probability to reach 90 and 100 years old was of 4.6% and 0.22% respectively. Accordingly, we observed significant lower mortality rates for all causes of death when compared to those measured in Palermo town. Therefore, the population …
Accelerated aging and life tests of optical fibers
The reliability of the network optical fibers is a critical issue for telecommunications.New investigations methods have been developed within a cooperative program supported by France Telecom. They include low coherence interferometry and optical near field microscopy in association with classical analysis tools such as Scanning Electron Microscopy and Shear Force Microscopy. One aim of the study is the localization and the characterization of the defects from which failure originates. The aging effect has been investigated in silica fibers immersed in desionized water at 65 oc and 85 "C for different times: from 3 to 12 months
