Newcomer S, Sauder C, Kuipers N, Laughlin M, Ray C
Am J Physiol Heart Circ Physiol
. 2008 Feb;
294(4):H1833-9.
PMID: 18245564
Shear rate is significantly lower in the superficial femoral compared with the brachial artery in the supine posture. The relative shear rates in these arteries of subjects in the upright...

Biomarkers
. 2007 Apr;
12(3):313-30.
PMID: 17453744
Assessing the pharmacodynamics (PD) of a potential therapeutic through the use of a downstream biomarker is essential. This is traditionally performed in the target tissue but limited volume and invasiveness...

Ray C, Carter J
Acta Physiol Scand
. 2003 Mar;
177(3):313-9.
PMID: 12609001
Aim: The vestibulosympathetic reflex refers to sympathetic nerve activation by the vestibular system. Animal studies indicate that the vestibular system assists in blood pressure regulation during orthostasis. Although human studies...

Ray C, Vasques M, Miller T, Wilkerson M, Delp M
J Appl Physiol (1985)
. 2001 Aug;
91(3):1207-13.
PMID: 11509517
The purpose of this study was to test the hypothesis that exposure to short-term microgravity or long-term hindlimb unloading induces cardiac atrophy in male Sprague-Dawley rats. For the microgravity study,...

Woodman C, Schrage W, Rush J, Ray C, Price E, Hasser E, et al.
J Appl Physiol (1985)
. 2001 Aug;
91(3):1091-8.
PMID: 11509503
We tested the hypothesis that hindlimb unweighting (HLU) decreases endothelium-dependent vasodilation and expression of endothelial nitric oxide synthase (eNOS) and superoxide dismutase-1 (SOD-1) in arteries of skeletal muscle with reduced...

Imadojemu V, Lott M, Gleeson K, Hogeman C, Ray C, Sinoway L
Am J Physiol Heart Circ Physiol
. 2001 Jun;
281(1):H371-5.
PMID: 11406505
We measured brachial and femoral artery flow velocity in eight subjects and peroneal and median muscle sympathetic nerve activity (MSNA) in five subjects during tilt testing to 40 degrees. Tilt...

Doerzbacher K, Ray C
J Appl Physiol (1985)
. 2001 Feb;
90(2):624-9.
PMID: 11160062
Previous studies suggest that prostaglandins may contribute to exercise-induced increases in muscle sympathetic nerve activity (MSNA). To test this hypothesis, MSNA was measured at rest and during exercise before and...

Ray C
J Appl Physiol (1985)
. 2001 Jan;
90(1):242-7.
PMID: 11133916
Evidence from animals indicates that skeletal muscle afferents activate the vestibular nuclei and that both vestibular and skeletal muscle afferents have inputs to the ventrolateral medulla. The purpose of the...

Cook D, OConnor P, Ray C
Am J Physiol Regul Integr Comp Physiol
. 2000 Oct;
279(5):R1565-73.
PMID: 11049837
The purpose of this experiment was to examine the effects of the endogenous opioid system on forearm muscle pain and muscle sympathetic nerve activity (MSNA) during dynamic fatiguing exercise. Twelve...

Am J Physiol Heart Circ Physiol
. 2000 Oct;
279(5):H2399-404.
PMID: 11045977
Muscle sympathetic nerve activity (MSNA) is altered by vestibular otolith stimulation. This study examined interactive effects of the vestibular system and baroreflexes on MSNA in humans. In study 1, MSNA...
