La seda: el hilo conductor de un itinerario cultural. Proyecto de implantación de la Ruta de la Seda en la provincia de Valencia.
2015
Las rutas culturales se están convirtiendo en poderosos recursos para activar y difundir un conjunto de bienes patrimoniales de muy diverso tipo, geográficamente distribuidos, de acuerdo a un argumento temático fundamentado de manera adecuada. El presente trabajo desarrolla el proyecto para implantar y poner en marcha una ruta cultural en torno a la seda en la provincia de Valencia. Su capital y su área de influencia (muchos municipios y comarcas cercanas) se configuraron, durante siglos, como el centro serícola por excelencia en la península ibérica, lo que dejó su impronta en la cultura material e inmaterial del territorio. En la actualidad estamos asistiendo a una corriente de recuperaci…
Analgesic and physiological effects in conscious sedation with different nitrous oxide concentrations
2015
Objectives: to study the physiological changes, as well as the psychosedative and analgesic effects of nitrous oxide, in experimental conditions. Study Design: 101 dental students volunteers participated in a single nitrous oxide sedation session without dental treatment. Signs and symptoms were registered during and after the procedure. Pulse rate and hemoglobin oxygen saturation were monitored at: 100 per cent O 2 , 30 per cent N 2 O, 50 per cent N 2 O and 5 minutes after 100 per cent O 2 . A Likert scale was used to evaluate pain perception. The analgesic effects of nitrous oxide were evaluated at: 30 per cent N 2 O, 50 per cent N 2 O, and five minutes postoperatively. Results: Pulse rat…
Determination of propofol by GC/MS and fast GC/MS-TOF in two cases of poisoning
2017
Two cases of suspected acute and lethal intoxication caused by propofol were delivered by the judicial authority to the Department of Sciences for Health Promotion and Mother-Child Care in Palermo, Sicily. In the first case a female nurse was found in a hotel room, where she lived with her mother; four 10 mg/mL vials and two 20 mg/mL vials of propofol were found near the decedent along with syringes and needles. In the second case a male nurse was found in the operating room of a hospital, along with a used syringe. In both cases a preliminary systematic and toxicological analysis indicated the presence of propofol in the blood and urine. As a result, a method for the quantitative determina…
Intraoperative tramadol reduces shivering but not pain after remifentanil–isoflurane general anaesthesia. A placebo-controlled, double-blind trial
2008
Background and objective Postoperative shivering and pain are frequent problems in patients recovering from anaesthesia with particularly high incidences being observed after remifentanil–isoflurane-based general anaesthesia. The opioid tramadol is generally effective in preventing shivering and treating pain, but its effects are not characterized after remifentanil-based general anaesthesia. This randomized, placebo-controlled, double-blind study evaluated the effects of intraoperative intravenous tramadol on postoperative shivering and pain after remifentanil-based general anaesthesia. Methods After Ethics Committee approval, 60 patients scheduled for lumbar disc surgery were included. Su…
