adenosine/edema

OBJECTIVE Adenosine has been shown to modulate various pathophysiologic conditions through receptor-mediated mechanisms. However, the role of adenosine in the pathogenesis of acute pancreatitis has not been described. We examined the effect of adenosine-receptor stimulation or inhibition on the

This study evaluated the pain enhancing properties of the adenosine A3 receptor agonist N6-benzyl-5'-N-ethylcarboxamidoadenosine (N6-benzyl-NECA) by assessing behavioural effects following s.c. administration alone to the dorsal hindpaw of the rat, or in combination with a low concentration of

We have previously demonstrated that adenosine plus homocysteine enhanced endothelial basal barrier function and protected against agonist-induced barrier dysfunction in vitro through attenuation of RhoA activation by inhibition of isoprenylcysteine-O-carboxyl methyltransferase. In the current

BACKGROUND Extracellular nucleotides mediate many cellular functions and are released in response to mechanical stress in vitro. It is unknown whether adenosine triphosphate (ATP) is released in vivo during mechanical ventilation (MV). We hypothesized that stress from high-pressure MV would increase

Urinary excretion and plasma concentrations of adenosine 3',5'-monophosphate were determined in idiopathic edema patients both at rest and after assumption of the upright position. Patients and normal subjects responded similarly to upright posture with decreases in urinary volume and creatine

Adenosine is the final product of ATP metabolism, mainly derived from the action of 5'-nucleotidase cleavage of AMP. Cellular production of adenosine is greatly enhanced in inflamed tissues, ischemic tissues, and under hypoxia, where ATP is released from damaged cells. Much evidence has been

Anthrax edema factor (EF) is a key virulence factor secreted by Bacillus anthracis. Here, we report a structure, at 3.0 A resolution, of the catalytic domain of EF (EF3) in complex with calmodulin (CaM) and adenosine 5'-(alpha,beta-methylene)-triphosphate (AMPCPP). Although the binding of the

OBJECTIVE To determine whether clinically relevant airspace concentrations of beta2-adrenergic agonists stimulated maximal alveolar fluid clearance rates and to determine whether beta2 agonist therapy decreased pulmonary edema in experimental acute lung injury. METHODS Prospective randomized

BACKGROUND Adenosine plays important roles in a variety of pathophysiologic conditions through receptor-mediated mechanisms. Recent studies have shown that adenosine exerts potent anti-inflammatory properties that are chiefly brought about through the occupancy of the A2a receptor. OBJECTIVE To

BACKGROUND No drug therapy has demonstrated improved clinical outcomes in the treatment of sepsis. A bolus of adenosine, lidocaine, and magnesium (ALM) has been shown to be cardioprotective and restore coagulopathy in different trauma states. We hypothesized that ALM therapy may improve

BACKGROUND Potassium aspartate (PA), as an electrolyte supplement, is widely used in clinical practice. In our previous study, we found PA had neuroprotective effects against apoptosis after cerebral ischemia/reperfusion in rats. In this study, we examine whether PA has protective effects on
