1.
Mathieu-Costello O, Ju Y, Trejo-Morales M, Cui L
J Appl Physiol (1985)
. 2005 Mar;
99(1):281-9.
PMID: 15774695
The objective was to examine whether muscle structural capacity for O2 flux (i.e., capillary-to-fiber surface ratio) relative to fiber mitochondrial volume deteriorates with the muscle atrophy of aging in predominantly...

Bernal D, Sepulveda C, Mathieu-Costello O, Graham J
J Exp Biol
. 2003 Jul;
206(Pt 16):2831-43.
PMID: 12847127
Tunas (family Scombridae) and sharks in the family Lamnidae are highly convergent for features commonly related to efficient and high-performance (i.e. sustained, aerobic) swimming. High-performance swimming by fishes requires adaptations...

Kanatous S, Davis R, Watson R, Polasek L, Williams T, Mathieu-Costello O
J Exp Biol
. 2002 Nov;
205(Pt 23):3601-8.
PMID: 12409486
In contrast to terrestrial animals that function under hypoxic conditions but display the typical exercise response of increasing ventilation and cardiac output, marine mammals exercise under a different form of...

Mathieu-Costello O, Morales S, Savolainen J, Vornanen M
J Appl Physiol (1985)
. 2002 Jun;
93(1):346-53.
PMID: 12070224
The objective was to examine fiber capillarization in relation to fiber mitochondrial volume in the highly aerobic diaphragm of the shrew, the smallest mammal. The diaphragms of four common shrews...
5.
Mathieu-Costello O
High Alt Med Biol
. 2001 Oct;
2(3):413-25.
PMID: 11682021
Prolonged exposure to high altitude leads to reduced muscle mass and performance. The fall in muscle mass follows a reduction in fiber size, which at first was believed to be...
6.
Hepple R, Mathieu-Costello O
J Appl Physiol (1985)
. 2001 Oct;
91(5):2150-6.
PMID: 11641356
Current evidence suggests that the size of the capillary-to-fiber (C/F) interface is a major determinant of O2 flux into muscle fibers, and methods have been developed for estimating the size...

Olfert I, Breen E, Mathieu-Costello O, Wagner P
J Appl Physiol (1985)
. 2001 Aug;
91(3):1176-84.
PMID: 11509513
Gene expression of vascular endothelial growth factor (VEGF), and to a lesser extent of transforming growth factor-beta(1) (TGF-beta(1)) and basic fibroblast growth factor (bFGF), has been found to increase in...

Kanatous S, Elsner R, Mathieu-Costello O
J Appl Physiol (1985)
. 2001 Apr;
90(5):1919-26.
PMID: 11299286
The purpose of this study was to examine muscle capillary supply in harbor seals. Locomotory and nonlocomotory muscles of four harbor seals (mass = 17.5-41 kg) were glutaraldehyde-perfusion fixed and...

Olfert I, Breen E, Mathieu-Costello O, Wagner P
J Appl Physiol (1985)
. 2001 Mar;
90(4):1532-8.
PMID: 11247956
Vascular endothelial growth factor (VEGF) is a hypoxia-inducible angiogenic mitogen. However, chronic hypoxia is generally not found to increase mammalian skeletal muscle capillarity. We sought to determine the effect of...

Effect of acute exercise on citrate synthase activity in untrained and trained human skeletal muscle
Leek B, Mudaliar S, Henry R, Mathieu-Costello O, Richardson R
Am J Physiol Regul Integr Comp Physiol
. 2001 Feb;
280(2):R441-7.
PMID: 11208573
Maximal citrate synthase activity (CS) is routinely used as a marker of aerobic capacity and mitochondrial density in skeletal muscle. However, reported CS has been notoriously variable, even with similar...
