Effects of α-tocopherol, β-carotene and ascorbic acid on oxidative, hormonal and enzymatic exercise stress markers in habitual training activity of professional basketball players

Background Intense physical exercise has been associated with an increase of free radical production. When the body's natural defense systems against free radicals are overwhelmed, oxidative stress increases. Aim of the study This study examined the effects of a vitamin antioxidant supplement, (composed of 600 mg α-tocopherol, 1000 mg ascorbic acid and 32 mg β-carotene) on oxidative, hormonal, and enzymatic exercise stress markers during habitual training activity over 35 days. Methods The plasma concentrations of ascorbic acid, α-tocopherol, β-carotene, testosterone, cortisol and lipid peroxides and the serum activities of lactate dehydrogenase and creatine kinase were measured at four tim…

Diet quality and lifestyle associated with free selected low-energy density diets in a representative Spanish population

Objective: Dietary intake is strongly influenced by the energy density of the diet. The purpose of this study was to determine the association of energy density with diet quality, dietary reference intake (DRI) for energy and lifestyle characteristics in free-living people. Subjects: The subjects were Spanish men (n ¼ 1491) and women (n ¼ 1563) selected in between 1999 and 2000 among the general population according to the 1996 census. Results: A low-energy density diet was significantly associated (Po0.001) with a higher consumption of vegetables, fruits, legumes, fish and white meat as compared to high-energy density diets. More subjects (Po0.001) with a high adherence to low-energy densi…

Tunable dispersion device based on a tapered fiber Bragg grating and nonuniform magnetic fields

We present a new variable dispersion device based on tuning the chirp of a tapered fiber Bragg grating by means of a magnetic transducer. By using a nonuniform magnetic field, we demonstrate a 188-472-ps/nm dispersion tuning range, suitable for tunable radio-frequency filters and dispersion compensation, among others.

Highly tunable optically switched time delay line for transversal filtering

A novel tunable dispersion device, based on two chirped fibre gratings subjected to non-uniform magnetic fields, is presented. A large degree of tunability is achieved from 250 to 750 ps/nm. This is used to demonstrate RF filtering in the 3-11 GHz range.
