Links between substance use habits, obesity, stress and the related cardiovascular outcomes can be, in part, because of loci with pleiotropic effects. To investigate this hypothesis, we performed genome-wide mapping in 119 multigenerational families from a population in the Saguenay-Lac-St-Jean region with a known founder effect using 58,000(More)
A personal computer-based image analysis system was developed for the three-dimensional mapping of cerebrocortical capillary networks from intravital video recordings. Capillary circulation in the parietal cortex of anesthetized rats was visualized to 70 microns depth using a closed cranial window preparation and epi-fluorescent, intensified video(More)
Using a novel approach for analysis of TRPC channel activity, we report here that NSAIDs are involved into regulation of TRPC channels in the podocytes of the freshly isolated decapsulated glomeruli. Fluorescence and electron microscopy techniques confirmed the integrity of podocytes in the glomeruli. Western blotting showed that TRPC1, 3 and 6 are highly(More)
With the draft sequence of the human genome available, there is a need to better define gene function in the context of systems biology. We studied 239 cardiovascular and renal phenotypes in 113 male rats derived from an F2 intercross and mapped 81 of these traits onto the genome. Aggregates of traits were identified on chromosomes 1, 2, 7, and 18. Systems(More)

Dahl salt-sensitive SS and consomic, salt-resistant SS-13(BN)/Mcw rats possess a highly similar genetic background but exhibit substantial differences in blood pressure salt sensitivity. We used cDNA microarrays to examine sequential changes of mRNA expression of approximately 2,000 currently known rat genes in the renal medulla (a tissue critical for(More)
Renal injury in the Dahl salt-sensitive rat mimics human salt-sensitive forms of hypertension that are particularly prevalent in black individuals, but the mechanisms that lead to the development of this injury are incompletely understood. We studied the impact of renal perfusion pressure (RPP) on the development of renal injury in this model. During the(More)
Leaders in the fields of Temporomandibular Disorders (TMD) and its accompanying overlapping pain conditions presented their latest findings at the Seventh Scientific Meeting of The TMJ Association, September 7-9, 2014, in Bethesda, MD. The meeting was co-sponsored by The TMJ Association and the National Institutes of Health. Topics of the scientific(More)
Recent studies have shown that the heme oxygenase (HO) product, carbon monoxide (CO), induces vasodilation and that inhibition of HO produces a sustained hypertension in rats. Given the importance of renal medullary blood flow (MBF) in the long-term control of arterial blood pressure, we hypothesized that the HO/CO system may play an important role in(More)
