Adequate nutrition is critically important for the achievement of the adolescent athlete's optimal performance. The purpose of the present study was to evaluate the adequacy of macro- and micro-nutrients in the adolescent Greek female volleyball players' diet. The subjects of the study consisted of 16 players who were members of the Junior National Team(More)
The role of A3 adenosine receptors (ARs) in sepsis and inflammation is controversial. In this study, we determined the effects of A3AR modulation on mortality and hepatic and renal dysfunction in a murine model of sepsis. To induce sepsis, congenic A3AR knockout mice (A3AR KO) and wild-type control (A3AR WT) mice were subjected to cecal ligation and double(More)
It was previously demonstrated that preischemic A(1) adenosine receptor (AR) activation protects renal function after ischemia-reperfusion (IR) injury in rats. The role of the A(1) AR in modulating inflammation, necrosis, and apoptosis in the kidney after IR renal injury was further characterized. C57BL/6 mice were subjected to 30 min of renal ischemia,(More)
Reactive airway disease predisposes patients to episodes of acute smooth muscle mediated bronchoconstriction. We have for the first time recently demonstrated the expression and function of endogenous ionotropic GABA(A) channels on airway smooth muscle cells. We questioned whether endogenous GABA(A) channels on airway smooth muscle could augment(More)
Sepsis is a leading cause of multiorgan dysfunction and death in hospitalized patients. Dysregulated inflammatory processes and apoptosis contribute to the pathogenesis of sepsis-induced organ dysfunction and death. A(1) adenosine receptor (A(1)AR) activation reduces inflammation and apoptosis after ischemia-reperfusion injury. Therefore, we questioned(More)
Airway smooth muscle (ASM) contraction is an important component of the pathophysiology of asthma. Taurine, an agonist of glycine receptor chloride (GlyR Cl(-)) channels, was found to relax contracted ASM, which led us to question whether functional GlyR Cl(-) channels are expressed in ASM. Messenger RNA for β (GLRB), α1 (GLRA1), α2 (GLRA2), and α4 (GLRA4)(More)
BACKGROUND Mortality from sepsis frequently results from multiple organ injury and dysfunction. Cecal ligation and puncture is an established murine model of septic peritonitis that produces septic shock characterized by an initial hyperinflammatory response. In addition to their anesthetic properties, local anesthetics have been shown to attenuate(More)
BACKGROUND Emerging evidence indicates that an endogenous autocrine/paracrine system involving gamma-aminobutyric acid (GABA) is present in airways. GABAA channels, GABAB receptors, and the enzyme that synthesizes GABA have been identified in airway epithelium and smooth muscle. However, the endogenous ligand itself, GABA, has not been measured in airway(More)
Airway smooth muscle hyperresponsiveness is a key component in the pathophysiology of asthma. Although calcium-activated chloride channel (CaCC) flux has been described in many cell types, including human airway smooth muscle (HASM), the true molecular identity of the channels responsible for this chloride conductance remains controversial. Recently, a new(More)
The prevalence of asthma has taken on pandemic proportions. Since this disease predisposes patients to severe acute airway constriction, novel mechanisms capable of promoting airway smooth muscle relaxation would be clinically valuable. We have recently demonstrated that activation of endogenous airway smooth muscle GABA(A) receptors potentiates(More)
