Oxidised LDLs might recruit monocytes and favour their transformation into foam cells through a receptor-mediated intake (scavenger pathway). Moreover oxidised LDLs show cytotoxic potential which is probably responsible for endothelial cell damage and macrophage degeneration in the atherosclerotic human plaque. Following the oxidation hypothesis of atherosclerosis the role of natural antioxidants, i.e. Vitamin C, Vitamin E and carotenoids, has been investigated in a large number of epidemiological, clinical and experimental studies. Animal studies indicate that dietary antioxidants may reduce atherosclerosis progression, and observational data in humans suggest that antioxidant vitamin ingestion is associated with reduced cardiovascular disease, but the results of randomised controlled trials are mainly disappointing. It has been suggested that natural antioxidants may be effective only in selected subgroups of patients with high levels of oxidative stress or depletion of natural antioxidant defence systems. The favourable effects shown by some studies relating antioxidant dietary intake and cardiovascular disease, may have been exerted by other chemicals present in foods. Flavonoids are the ideal candidates, since they are plentiful in foods containing antioxidant vitamins (i.e. fruits and vegetables) and are potent antioxidants. Tea and wine, rich in flavonoids, seem to have beneficial effects on multiple mechanisms involved in atherosclerosis. Future studies should probably select patients in a context of high-oxidative stress \/ low-antioxidant defence, to verify if antioxidants may really prove useful as therapeutic anti-atherosclerotic agents.<\/p>\n","protected":false},"template":"","mots_cles":[],"class_list":["post-50401","resume","type-resume","status-publish","hentry"],"acf":{"adresse":"Institute of Gerontology and Geriatrics, Department of Clinical and Experimental Medicine, University of Perugia Medical School, Policlinico Monteluce, padiglione E , via Brunamonti , 06122, Perugia Italy. acherub@unipg.it","annee":"2005","mois":"0","numero":"11:16","page":"2017-2032","auteurs":[{"ID":50397,"post_author":"0","post_date":"2018-12-04 05:16:02","post_date_gmt":"2018-12-04 04:16:02","post_content":"","post_title":"Senin","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"senin","to_ping":"","pinged":"","post_modified":"2018-12-04 05:16:02","post_modified_gmt":"2018-12-04 04:16:02","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/senin\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":49318,"post_author":"0","post_date":"2018-12-04 04:54:54","post_date_gmt":"2018-12-04 03:54:54","post_content":"","post_title":"Cherubini","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"cherubini","to_ping":"","pinged":"","post_modified":"2018-12-04 04:54:54","post_modified_gmt":"2018-12-04 03:54:54","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/cherubini\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":50398,"post_author":"0","post_date":"2018-12-04 05:16:03","post_date_gmt":"2018-12-04 04:16:03","post_content":"","post_title":"Vigna","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"vigna","to_ping":"","pinged":"","post_modified":"2018-12-04 05:16:03","post_modified_gmt":"2018-12-04 04:16:03","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/vigna\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":50399,"post_author":"0","post_date":"2018-12-04 05:16:04","post_date_gmt":"2018-12-04 04:16:04","post_content":"","post_title":"Zuliani","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"zuliani","to_ping":"","pinged":"","post_modified":"2018-12-04 05:16:04","post_modified_gmt":"2018-12-04 04:16:04","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/zuliani\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":49319,"post_author":"0","post_date":"2018-12-04 04:54:55","post_date_gmt":"2018-12-04 03:54:55","post_content":"","post_title":"Ruggiero","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"ruggiero-2","to_ping":"","pinged":"","post_modified":"2018-12-04 04:54:55","post_modified_gmt":"2018-12-04 03:54:55","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/ruggiero-2\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":50400,"post_author":"0","post_date":"2018-12-04 05:16:05","post_date_gmt":"2018-12-04 04:16:05","post_content":"","post_title":"Fellin","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"fellin","to_ping":"","pinged":"","post_modified":"2018-12-04 05:16:05","post_modified_gmt":"2018-12-04 04:16:05","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/fellin\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"}],"sources":[{"ID":7801,"post_author":"0","post_date":"2018-12-03 17:53:03","post_date_gmt":"2018-12-03 16:53:03","post_content":"","post_title":"Current pharmaceutical design","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"current-pharmaceutical-design","to_ping":"","pinged":"","post_modified":"2018-12-03 17:53:03","post_modified_gmt":"2018-12-03 16:53:03","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/source\/current-pharmaceutical-design\/","menu_order":0,"post_type":"source","post_mime_type":"","comment_count":"0","filter":"raw"}]},"yoast_head":"<!-- This site is optimized with the Yoast SEO Premium plugin v23.6 (Yoast SEO v23.6) -
