Conjugated linoleic acids: why the discrepancy between animal and human studies?
Conjugated linoleic acids (CLA) are positional and geometric isomers of linoleic acid. In animals, CLA consumption reduces body fat but results in humans are less conclusive. This review of the literature on CLA and loss ...
Plasma omega-3 fatty acid response to a fish oil supplement in the healthy elderly
Other titre : Plasma response to fish oil in the elderly
Little information is available concerning whether incorporation of dietary omega-3 fatty acids into plasma lipids changes during healthy aging. Elderly (74 ± 4 years old) and young (24 ± 2 years old) adults were given a ...
Mechanisms of active laryngeal closure during non-invasive intermittent positive pressure ventilation in non-sedated lambs
The present study stems from our recent demonstration (Moreau-Bussiere F, Samson N, St-Hilaire M, Reix P, Lafond JR, Nsegbe E, Praud JP. J Appl Physiol 102: 2149-2157, 2007) that a progressive increase in nasal intermittent ...
Origins of the inhibiting effects of nasal CPAP on non-nutritive swallowing in newborn lambs
The present study was aimed at investigating the principal reflex mechanism by which non-nutritive swallowing (NNS) is inhibited by application of a nasal CPAP 6 cm H2O during quiet sleep (QS) in newborn lambs. Eighteen ...
Interspeciﬁc associations between circulating antioxidant levels and life-history variation in birds
Abstract: Antioxidants play an important role in protecting tissues against aging-associated oxidative damage and are thus prime candidates for relating physiological mechanisms to variation in life histories. We measured ...
Stress, metabolism, and antioxidants in two wild passerine bird species
Abstract: Antioxidants protect against free-radical damage, and free radicals, in turn, are thought to underlie aging. Thus, measuring antioxidants mayaid ﬁeldecologistsinunderstandingthephysiological mechanisms that ...
