OBJECTIVE To evaluate the effect of a norepinephrine-induced differential increase in mean arterial pressure on splanchnic and renal perfusion in a porcine model of volume-resuscitated endotoxic shock. DESIGN Prospective, controlled, acute interventional study. SETTING Animal research laboratory. SUBJECTS Fourteen landrace pigs, seven treated with(More)
Fluoride is one of the most effective agents for the treatment of vertebral osteoporosis because of its ability to increase osteoblast proliferation. The present study further investigates the role of protein tyrosine phosphorylation previously suggested to mediate the mitogenic effect of fluoride on bone-forming cells. The activity of the plasma membrane(More)
Osteosclerosis in workers exposed to fluoride (F) and aluminum (Al) (industrial fluorosis) led to the use of F as a treatment to increase bone mass in osteoporosis patients. Because the influence of traces of Al on the effects of F on bone formation is heretofore unknown, we have investigated this issue both in vitro and in vivo. We have found that minute(More)
BACKGROUND To investigate endothelin-1 (ET-1)-dependent hepatic and mesenteric vasoconstriction, and oxygen and lactate fluxes in an acute, fixed low cardiac output (CO) state. METHODS Sixteen anesthetized, mechanically ventilated pigs were studied. Cardiac tamponade was established to reduce portal venous blood flow (Q(PV)) to 2/3 of the baseline value.(More)
We describe a patient who presented with high rate ventricular pacing secondary to dysfunction of his implantable cardioverter defibrillator (ICD). The device was also unable to communicate with the programmer and unable to treat ventricular fibrillation. Immediate disconnection of the ICD from the leads was the only effective recourse. Subsequent detailed(More)
The effect of aluminum (AI) on inorganic phosphate (P(i)) transport stimulation induced by fluoride (F) was investigated in MC3T3-E1 osteoblast-like cells. Al potentiated the increase in P(i) transport activity induced by F in a dose- and time-dependent manner. Results obtained with deferoxamine mesylate, an Al chelator, suggest that a fluoroalumino complex(More)
OBJECTIVE To study the importance of endothelin-1-induced vasoconstriction in a model of acute and maintained low cardiac output, by investigating regional changes within the mesenteric and particularly the intestinal mucosal circulation. DESIGN Prospective, controlled animal study. SETTING University-affiliated research laboratory. SUBJECTS Thirteen(More)
