Intravenous (IV) stem cell delivery for regenerative tissue therapy has been increasingly used in both experimental and clinical trials. However, recent data suggest that the majority of administered stem cells are initially trapped in the lungs. We sought to investigate variables that may affect this pulmonary first-pass effect. In anesthetized(More)
We hypothesized that the interaction between tumor necrosis factor-alpha (TNF-alpha)/nuclear factor-kappaB (NF-kappaB) via the activation of IKK-beta may amplify one another, resulting in the evolution of vascular disease and insulin resistance associated with diabetes. To test this hypothesis, endothelium-dependent (ACh) and -independent (sodium(More)
Coronary arterioles from hypercholesterolemic swine display attenuated adenosine-mediated vasodilatation that is attributable to the elimination of voltage-dependent K(+) (Kv) channel stimulation. For the present study, we tested the hypotheses that exercise training would correct impaired adenosine-induced dilatation in coronary arterioles from(More)
Myocardial interstitial edema forms as a result of several disease states and clinical interventions. Acute myocardial interstitial edema is associated with compromised systolic and diastolic cardiac function and increased stiffness of the left ventricular chamber. Formation of chronic myocardial interstitial edema results in deposition of interstitial(More)
Intra-abdominal hypertension leading to abdominal compartment syndrome complicates trauma resuscitation. The purpose of this study was to determine the effect of primary (1 degrees) and secondary (2 degrees) intra-abdominal hypertension (IAH) on hemodynamics, intestinal fluid balance, and mesenteric lymph flow. Anesthetized dogs were instrumented with(More)
High volume resuscitation and damage control surgical methods, while responsible for significantly decreasing morbidity and mortality from traumatic injuries, are associated with pathophysiologic derangements that lead to subsequent end organ edema and dysfunction. Alterations in hydrostatic and oncotic pressures frequently result in intestinal edema and(More)
The lymphatic system returns interstitial fluid to the central venous circulation, in part, by the cyclical contraction of a series of "lymphangion pumps" in a lymphatic vessel. The dynamics of individual lymphangions have been well characterized in vitro; their frequencies and strengths of contraction are sensitive to both preload and afterload. However,(More)
BACKGROUND Management of the open abdomen is an increasingly common part of surgical practice. The purpose of this review is to examine the scientific background for the use of temporary abdominal closure (TAC) in the open abdomen as a way to modulate the local and systemic inflammatory response, with an emphasis on decompression after abdominal compartment(More)
BACKGROUND Recent studies suggest that peritoneal fluid (PF) may be an important mediator of inflammation. The aim of this study was to test the hypothesis that PF may drive systemic inflammation in intra-abdominal sepsis by representing a priming agent for neutrophils. METHODS PF was collected 12 hours after the initiation of intra-abdominal sepsis in(More)
To return lymph to the great veins of the neck, it must be actively pumped against a pressure gradient. Mean lymph flow in a portion of a lymphatic network has been characterized by an empirical relationship (P(in) - P(out) = -P(p) + R(L)Q(L)), where P(in) - P(out) is the axial pressure gradient and Q(L) is mean lymph flow. R(L) and P(p) are empirical(More)
