Cysteinyl leukotrienes (CysLTs) exert potent proinflammatory actions and contribute to many of the symptoms of asthma. Using a model of allergic sensitization and airway challenge with Aspergillus fumigatus (Af), we have found that Th2-type inflammation and airway hyperresponsiveness (AHR) to methacholine (MCh) were associated with increased LTD(4) responsiveness in mice. To explore the importa...
BACKGROUND Hypnotic depth but not haemodynamic responsiveness is measured with EEG-based monitors. In this study we compared heart rate variability (HRV) in unstimulated patients and stimulation-induced HRV at different levels of anaesthesia. METHODS A total of 95 ASA I or II patients were randomly assigned to five groups (Group 1: BIS 45(5), remifentanil 1 ng ml(-1); Group 2: BIS 45(5), remi...
Interleukin (IL)-1beta is a pleiotropic, pro-inflammatory cytokine that has been importantly implicated in driving the inflammatory response and resultant changes in airway smooth muscle (ASM) responsiveness in asthma. IL-1beta belongs to a family of molecules, known as the IL-1 axis, which exert both pro- and anti-inflammatory effects. Since dysregulation of IL-1 axis molecules may be critical...
INTRODUCTION Fluid responsiveness prediction is difficult in spontaneously breathing patients. Because the swings in intrathoracic pressure are minor during spontaneous breathing, dynamic parameters like pulse pressure variation (PPV) and systolic pressure variation (SPV) are usually small. We hypothesized that during spontaneous breathing, inspiratory and/or expiratory resistors could induce h...
Studies that evaluate the mechanisms for increased airway responsiveness are very sparse, although there are reports of exercise-induced bronchospasm. Therefore, we have evaluated the tracheal reactivity and the rate of lipid peroxidation after different intensities of swimming exercise in rats. Thus, male Wistar rats (age 8 weeks; 250-300 g) underwent a forced swimming exercise for 1h whilst c...
mental disorders are known to be an important cause of disabilities worldwide. despite their importance, about two thirds of mentally ill people do not seek treatment, probably because of the mental health system's inability to decrease the negative side effects of the interaction with the mental health services. the world health organization has suggested the concept of responsiveness as a way...
