Journal ArticleDOI
Effects of experimental weight perturbation on skeletal muscle work efficiency in human subjects.
Michael Rosenbaum,Krista Vandenborne,Rochelle L. Goldsmith,Jean-Aimé Simoneau,Steven B. Heymsfield,Denis R. Joanisse,Jules Hirsch,Ellen Murphy,Dwight E. Matthews,Karen R. Segal,Rudolph L. Leibel +10 more
TL;DR: Examination of skeletal muscle work efficiency by graded cycle ergometry and rates of gastrocnemius muscle ATP flux during exercise by magnetic resonance spectroscopy found changes in muscle efficiency at altered body weight accounted for 35% of the change in daily energy expended in physical activity.
Journal ArticleDOI
Muscle Atrophy and Hypertrophy Signaling in Patients with Chronic Obstructive Pulmonary Disease
Mariève Doucet,Aaron P. Russell,Bertrand Léger,Richard Debigaré,Denis R. Joanisse,Marc-André Caron,Pierre LeBlanc,François Maltais +7 more
TL;DR: The overexpression of the muscle hypertrophic signaling pathways found in patients with COPD with muscle atrophy could represent an attempt to restore muscle mass.
Journal ArticleDOI
Fat content in individual muscle fibers of lean and obese subjects
Patrick Malenfant,Denis R. Joanisse,R Thériault,Bret H. Goodpaster,David E. Kelley,Jean-Aimé Simoneau +5 more
TL;DR: The higher number of lipid aggregates and the disposition to a greater central distribution in all fiber types in obesity indicate important changes in lipid metabolism and/or storage that are fiber type-independent.
Journal ArticleDOI
Effects of experimental weight perturbation on skeletal muscle work efficiency, fuel utilization, and biochemistry in human subjects
Rochelle L. Goldsmith,Denis R. Joanisse,Dympna Gallagher,Katherine H. Pavlovich,Elisabeth L. Shamoon,Rudolph L. Leibel,Michael Rosenbaum +6 more
TL;DR: In this article, the authors performed biochemical analysis of vastus lateralis muscle needle biopsy samples to determine whether maintenance of an altered body weight was associated with changes in skeletal muscle histomorphology.
Journal ArticleDOI
Oxidative damage and antioxidants in Rana sylvatica, the freeze-tolerant wood frog
TL;DR: Correlative data showing increased activities of some antioxidant enzymes during freezing, as well as constitutively higher activities of antioxidant enzymes and higher levels of glutathione in the freeze-tolerant species compared with Rana pipiens, suggest that antioxidant defenses play a key role in amphibian freeze tolerance.
