IRIS Institutional Research Information System - AIR Archivio Istituzionale della Ricerca

IRIS è il sistema di gestione integrata dei dati della ricerca (persone, progetti, pubblicazioni, attività) adottato dall'Università degli Studi di Milano.

AIR nasce in UNIMI nel 2006 con lo scopo di raccogliere, documentare e conservare le informazioni sulla produzione scientifica dell'Università degli Studi di Milano e costituisce di fatto l'Anagrafe della ricerca dell'Ateneo.

Early detection of inflammation in neonatal calves allows early intervention, which may reduce mortality. Paraoxonase-1 (PON1) is a negative acute phase protein in humans. The aims of this study were to investigate age-related variability in serum PON1 activity and its clinical usefulness in neonatal calves. In healthy calves (n = 9), PON1 activity increased with age from 2 to 21 days of age. There was no significant increase in PON1 activity in healthy calves from days 21 to 120 (n = 15), but PON1 activity was significantly higher in adult cattle (n = 45). In sick calves, serum PON1 was significantly lower in calves <7 days of age with diarrhoea (n = 8) and in calves >28- to 120-days-old with respiratory disease (n = 8) in comparison with age matched controls (n = 20 and n = 15, respectively). These results support the role of PON1 as a negative acute phase protein in cattle.
