Background: The outcome of coronary diseases is influenced by lifestyle and diet. Among dietary factors, n-3 polyunsaturated fatty acids reduce mortality from cardiovascular diseases.

Aims: To evaluate the impact of dietary and lifestyle advice by calculation of scores and analysis of plasmatic lipids and the fatty acid composition of erythrocyte membrane phospholipids after 1 year of patient education in 66 patients with acute coronary syndromes.

Objectives: This work aims to evaluate the resistance of mononuclear cells to oxidative stress using a "KRL" test, formerly utilized to evaluate the resistance of erythrocyte to free radicals.

Methods: The "KRL" test evaluates the resistance to lysis of cells treated by free radicals generated under standardized conditions.

Results: We defined new analytical parameters (level of radical production, time course, number of cells) to obtain an accurate assay determining the resistance to oxidative stress of mononuclear cells, in comparison to that of erythrocytes.

We report 19 episodes of hypercalcemia in three children treated with 13-cis-retinoic acid (13-cis-RA) as a post-consolidation therapy for high-risk neuroblastoma. There was no concomitant overload in 13-cis-RA blood levels. Blood calcium fell after arrest of 13-cis-RA intake.

Signaling of all-trans retinoic acid (ATRA) through nuclear retinoid acid (RA) receptors regulates several biological functions in airway epithelial cells, eosinophils, and immune cells, yet its impact on different in vivo aspects of pulmonary allergic reaction remains elusive. We compared the effect of a treatment with liposomally encapsulated ATRA (Lipo-ATRA) in a mouse model of ovalbumin (OVA)-induced T helper (Th) 2-type responses and airway remodeling. Daily intraperitoneal injections of 10 mg/kg Lipo-ATRA, at the time of each of the 2 systemic sensitizing injections, increased OVA-induced Immunoglobulin E synthesis, bronchoalveolar lavage (BAL) eosinophilia, and accumulation of IL-5, transforming-growth factor beta1, fibronectin, eotaxin/chemokine (C-C motif) ligand 11 (eotaxin/CCL11) and regulated upon activation, normal T expressed and secreted chemokine (C-C motif) ligand 5.

Adipose tissues are differently involved in lipid metabolism and obesity according to their type and location. Increasing reports stress on the impact of redox metabolism on obesity and metabolic syndrome. The aim of this work is to investigate the site-specific redox metabolism in three different adipose tissues and its changes occurring in obesity.

The role of inflammation and oxidative stress in the development of obesity and associated metabolic disorders is under debate. We investigated the redox metabolism in a non-diabetic obesity model, i.e.

Background: Reference values of numerous micronutrients at different gestational ages (GA) have not been yet reported based on large series.

Aims: This study aimed to establish the reference range for zinc, copper, selenium, vitamin A, vitamin E, retinol binding protein, transthyretin, albumin, transferrin and ceruloplasmin in neonates and to give the profiles according to gestational age.

Study Design: A total of 510 infants appropriate for gestational age were included in the study.
