Percepción del alumnado sobre el uso del método AICLE en Educación Física: estudio de caso (Students’ perception of the use of CLIL method in Physica…
2017
El Aprendizaje Integrado de Contenidos y Lengua Extranjera (AICLE) está siendo cada vez más extendido e investigado en el panorama educativo español. Dada la importancia de la motivación y la predisposición del alumnado para que el proceso de enseñanza-aprendizaje sea efectivo, este estudio de caso analiza la percepción de un grupo de secundaria durante la aplicación del método AICLE en la asignatura de Educación Física. Se optó por un enfoque metodológico cualitativo apoyado en la triangulación de diarios de reflexión del alumnado, registro anecdótico del profesor-investigador y un focus group. Los resultados afianzan el actual estado de la cuestión, desvelando cinco categorías sobre las q…
Effect of depth of neuromuscular blockade on the abdominal space during pneumoperitoneum establishment in laparoscopic surgery.
2015
To evaluate the effect of neuromuscular blockade (NMB) upon the abdominal space during pneumoperitoneum establishment in laparoscopic surgery, comparing moderate NMB and deep NMB.Prospective, randomized, crossover clinical trial.Operating room.Seventy-six American Society of Anesthesiologists 1 to 2 patients scheduled for elective laparoscopic surgery.Two independent evaluations were performed at the establishment of pneumoperitoneum for a preset intraabdominal pressures (IAPs) of 8 and 12 mm Hg, both during moderate NMB (train-of-four count, 1-3) and deep NMB (posttetanic count,5). Rocuronium was used to induce NMB, and sugammadex was used for reversal.We evaluated (i) the volume of CO2 in…
Prevention of the acute neurotoxic effects of phenytoin on rat peripheral nerve by H7, an inhibitor of protein kinase C.
1992
Abstract The neurotoxic effects of a single dose of phenytoin (150 mg/kg body weight) alone or 30 min after H7 (a protein kinase C inhibitor) injection (20 mg/kg body weight) were investigated in terms of peripheral neuromuscular function and Na + ,K + -ATPase activity of the sciatic nerve. This intraperitoneal injection of phenytoin induced complete blockade of muscle action potentials in the dorsal segmental muscles of the rat tail evoked by electric stimulation of the caudal nerve and a 40% decrease in the Na + ,K + -ATPase activity of the rat sciatic nerve when compared with control values, measured as the difference between total and ouabain-insensitive ATPase activity. Prior administr…
Influence of depth of neuromuscular blockade on surgical conditions during low-pressure pneumoperitoneum laparoscopic cholecystectomy: A randomized b…
2017
Abstract Study objective To evaluate the influence of neuromuscular blockade (NMB) on surgical conditions during low-pressure pneumoperitoneum (8mmHg) laparoscopic cholecystectomy (LC), while comparing moderate and deep NMB. Secondary objective was to evaluate if surgical conditions during low-pressure pneumoperitoneum LC performed with deep NMB could be comparable to those provided during standard-pressure pneumoperitoneum (12mmHg) LC. Design Prospective, randomized, blinded clinical trial. Setting Operating room. Patients Ninety ASA 1–2 patients scheduled for elective LC. Interventions Patients were allocated into 3 groups: Group 1: low-pressure pneumoperitoneum with moderate-NMB (1–3 TOF…
Phenytoin-induced glutathione depletion in rat peripheral nerve
1995
Abstract Administration of high doses (150–250 mg/kg body weight) of phenytoin (DPH) promote a 40% decrease in glutathione (GSH) content of rat sciatic nerve. This DPH-induced GSH depletion is accompanied with an electrophysiological impairment of peripheral neuromuscular function. H7 (20 mg/kg body weight IP, 30 min prior to DPH), a protein kinase C inhibitor, was able to prevent the DPH-induced GSH depletion only at the lower DPH dose used. This same inhibitor completely prevented the electrophysiological impairment at the lower DPH dose, and only partially at the higher DPH dose used. These results confirm the hypothesis of a DPH-dependent activation of PKC (that might be triggered by, o…
Temperature dependence of the toxic effects of phenytoin on peripheral neuromuscular function of the rat tail.
1990
We studied the acute effects of a single dose of phenytoin (250 mg/kg) on peripheral neuromuscular function. The evoked muscle action potentials of the dorsal segmental muscles in the rat tail, and the conduction velocity of the dorsal nerve trunk which innervates them, were measured before and after the intraperitoneal injection of phenytoin. The experiments were performed at different temperatures, 27 (physiological tail temperature), 36 and 37 degrees C (physiological central temperature) in different groups of animals. The amplitudes of the evoked muscle action potentials in the treated groups showed no significant modifications at 27 degrees C, at 36 degrees C a small nonsignificant de…
