Cardiac trauma has been recognized as a complication associated with blunt chest trauma involving coronary artery injury, myocardium contusion and myocardial rupture. Secondary cardiac injuries after trauma supposed to be a critical factor in trauma patients, but the mechanism is not fully explored. Overproduction of TNF-alpha had been reported in multiple trauma animals, this induces oxidative stress resulting in cardiac apoptosis. Apoptosis gradually increases after trauma and reaches to a maximum level in 12 h time...

Correlating the Raman and infrared spectra of shocked minerals in Csátalja ordinary chondrite (H4, S2, W2) with controlling the composition by EPMA measurements, we identified and improved various shock indicators, as infrared spectro-microscopic analysis has been poorly used for shock impact alteration studies of meteorites to date. We also provide reference spectra as SOM for the community with local mineralogical and shock alteration related context to support further standardization of the IR ATR based measurements...

β-adrenergic receptor agonists such as isoproterenol can induce cutaneous vasodilatation and sweating in humans, however, the mechanisms underpinning this response remains unresolved. We evaluated the hypotheses that 1) nitric oxide synthase (NOS) contributes to β-adrenergic cutaneous vasodilatation, whereas cyclooxygenase (COX) limits the vasodilatation, and 2) COX contributes to β-adrenergic sweating. In 10 young males (25 ± 5 years), cutaneous vascular conductance (CVC) and sweat rate were evaluated at four intradermal forearm skin sites infused with 1) lactated Ringer's (control), 2) 10 mm L -NNA, a non-specific NOS inhibitor, 3) 10 mM ketorolac, a non-specific COX inhibitor, or 4) a combination of L -NNA and ketorolac...

BACKGROUND & OBJECTIVES: Most anesthesiologists use the injection of a test dose of local anesthetic in order to evaluate the final needle tip position. Thus, the intraneural injection of a full dose can be avoided. The aim of this study was to analyze whether an intraneural injection of a test dose of bupivacaine could trigger histological changes. METHODS: Intraneural injections under direct vision were performed in 40 brachial plexus nerves in seven anesthetized pigs...

BACKGROUND: Insomnia is a robust correlate of suicidal ideation and behavior. Preliminary research has identified thwarted belongingness (c.f. social disconnection) as an explanatory link between insomnia and suicidal ideation. OBJECTIVES: This study replicates and extends previous findings using both cross-sectional and longitudinal designs in four demographically diverse samples. Additionally, the specificity of thwarted belongingness was evaluated by testing anxiety as a rival mediator...

BACKGROUND: Clinical studies have demonstrated that the early and empiric use of plasma improves survival after hemorrhagic shock. We have demonstrated in rodent models of hemorrhagic shock that resuscitation with plasma is protective to the lungs compared with lactated Ringer's solution. As our long-term objective is to determine the molecular mechanisms that modulate plasma's protective effects in injured bleeding patients, we have used human plasma in a mouse model of hemorrhagic shock...

During exercise, cutaneous vasodilation and sweating responses occur, whereas these responses rapidly decrease during postexercise recovery. We hypothesized that the activation of endothelin A (ETA) receptors, but not endothelin B (ETB) receptors, attenuate cutaneous vasodilation during high-intensity exercise and contribute to the subsequent postexercise suppression of cutaneous vasodilation. We also hypothesized that both receptors increase sweating during and following high-intensity exercise. Eleven males (24 ± 4 years) performed an intermittent cycling protocol consisting of two 30-min bouts of moderate- (40% VO2peak) and high- (75% VO2peak) intensity exercise in the heat (35°C), each separated by a 20- and 40-min recovery period, respectively...

BACKGROUND: A recent review article suggests that elimination of infused crystalloid fluid might occur faster in females than in males. To study this question, a population kinetic analysis was performed to compare the turnover of buffered Ringer's solution when infused at different rates in males and females. METHODS: Data were retrieved from seven series of experiments where 44 intravenous infusions of Ringer's acetate had been given to female volunteers and 67 to male volunteers...

IFN regulatory factor (IRF)3 plays a detrimental role in the cecal ligation and puncture (CLP) mouse model of sepsis. However, it is unclear which pathway activates IRF3 in this context. In this report we investigate two pathways that activate IRF3: the Stimulator of Interferon Genes (STING) pathway (which senses cytosolic DNA) and the TIR-domain-containing adapter-inducing interferon-β (TRIF) pathway (which sense dsRNA and LPS via Toll-like receptor (TLR) 3 and 4). Initially, we examine the impact of these pathways using a severe CLP model (∼90% mortality)...

BACKGROUND: Spinal anesthesia is a preferred technique over general anesthesia for cesarean delivery. It avoids maternal airway related complications, aspiration and neonatal depression. However hypotension following spinal anesthesia can lead to decrease in uterine blood flow and neonatal hypoxia. AIMS: We aimed to evaluate the efficacy of 15 1of crystalloid preloading versus prophylactic intravenous bolus of 10 mg ephedrine as an antihypotensive measure for cesarean section...

BACKGROUND: A major change in anesthesia practice as regards to intraoperative infusion therapy is the present requirement. Switching over to balanced fluids can substantially decrease the incidence of lactic acidosis and hyperchloremic acidosis. The deleterious effects of unbalanced fluids are more recognizable during major surgeries. We prospectively studied the influence of Sterofundin (SF) and Ringer lactate (RL) on acid-base changes, hemodynamics, and readiness for extubation during scoliosis surgery...

OBJECTIVE: Neurosurgery in general anesthesia exposes patient to hemodynamic alternations both in prone and sitting position. As the comparison of the sitting and prone position in neurosurgery is scarce, we aimed to evaluate hemodynamic profile during stroke volume-directed fluid administration in patients undergoing neurosurgery either in sitting or prone position. METHODS: Thirty patients in prone and 28 in sitting position in two separate prospective trials were randomized to receive either Ringer's Acetate (RAC) or hydroxyethyl starch (HES 130 kDa/0...
