Since the work of McCay in 1935, demonstrating the effect of energy restricted diet on the lifespan of rats, many studies have confirmed these findings in different species. Several mechanisms have been suggested, including among others, growth retardation, diminished apoptosis, decreased oxidative damage, altered glucose utilization, changes in gene(More)
OBJECTIVE To evaluate the distribution pattern of the main macronutrients (protein, fat, carbohydrates) and fiber in a selected well-established group of elderly people, average age above 80 years. METHOD Dietary consumption was evaluated in a well-established group of 21 elderly people in a home for the aged by in-person interview using a food frequency(More)
Elevated fasting plasma total homocysteine concentration (tHcy) and lower vitamin status are associated with atherosclerotic states. Silent brain ischemic lesions and brain atrophy, prevailing in the elderly, are affected by tHcy and vitamin status. The study was performed on 56 outpatients who had undergone brain computed tomography (CT) before the onset(More)
During the 20th century, the average lifespan in the industrialized societies has enormously increased and it is still rising. With the increase in the number of old people, a parallel increase in the number of the disabled elderly is postulated. Thus, the whole society might suffer from an imbalance between the productive segment of the society and a huge(More)
To measure the activation coefficient (AC) of erythrocyte glutathione reductase (GR), suspended whole blood was lysed in a preincubation solution, with or without 100 microM flavin adenine dinucleotide (FAD). Upon addition of the reaction mixture, FAD concentration decreased about 10-fold. No AC values < 1 were obtained in any of the subjects. The range of(More)
OBJECTIVE Our objective was to examine gender differences in height and weight associated with socioeconomic status (SES) and the consequent effect on body mass index in a multiethnic society.
