Study of the contributions of non-specific and specific interactions during flu...
Valente Nabais, Joao; Roman, Silvia; Gonzalez, Juan; Garcia, Carmen; Ortiz, AngelThe adsorption of fluoxetine onto activated carbons (ACs) prepared from almond tree pruning by steam and CO2 activation under different temperature conditions (650– 9508C), was studied. In both series increasing the temperature caused an increase in the BET apparent surface area, yielding ACs with SBET up to 870 and 710m2 g 1 after steam and CO2 activation, respectively. Also, a slight widening of the porosity ...
Porosity Development in Activated Carbons Prepared from Walnut Shells by Carbon...
Roman, Silvia; Gonzalez, Jose; Garcia, Carmen; Valente Nabais, Joao; Ortiz, AntonioThe influence of carbon dioxide and steam as activating agents on the porosity development of activated carbons produced from walnut shells was investigated. The study was made covering a wide range of burnoff (12-76%) and employing different temperatures and times: in carbon dioxide activation, 850 °C varying the activation time in the range 60-480 min, and in steam activation, 700, 850, and 900 °C (for 30-120...

Naloxone inhibits nicotine-induced receptor current and catecholamine secretion...
Tomé, Angelo R.; Izaguirre, Victor; Rosário, Luís M.; Ceña, Valentín; González-García, CarmenNicotine-induced catecholamine (CA) secretion and inward ionic currents were inhibited by the opioid antagonist naloxone in cultured bovine chromaffin cells. Naloxone inhibited nicotine-induced CA secretion, as detected by an on-line real-time electrochemical technique, in a dose-dependent manner (IC50=29 [mu]M). In voltage-clamped chromaffin cells, nicotine (10 [mu]M) evoked an average peak inward current of -...
