Determination of procaine and tetracaine in plasma samples by micellar liquid chromatography and direct injection of sample

2001

A liquid chromatographic procedure is proposed for the determination of procaine and tetracaine in plasma samples with direct injection. The method uses a Spherisorb octadecylsilane ODS-2 C18 analytical column and a micellar mobile phase containing 0.15 M sodium dodecyl sulphate, 0.5% triethylamine at pH 2.5 and 10% propanol. The UV detection was carried out at 300 nm. Plasma sample preparation required only adequate dilution with the mobile phase before injection into the chromatographic system. The proposed method allows the determination of procaine and tetracaine in plasma at therapeutic levels.

Atropine-resistant effects of the muscarinic agonists McN-A-343 and AHR 602 on cardiac performance and the release of noradrenaline from sympathetic …

1974

Abstract 1 The effects of 4-(m-chlorophenylcarbamoyloxy)-2-butynyltrimethylammonium chloride (McN-A-343) and N-benzyl-3-pyrrolidyl acetate methobromide (AHR 602) on cardiac performance and noradrenaline release from terminal sympathetic fibres were measured in isolated perfused hearts of rabbits. 2 In the presence of sufficient atropine to block muscarinic receptors, high concentrations of McN-A-343 and AHR 602 caused no cardiac stimulation and there was no increase in the resting output of noradrenaline into the perfusates. 3 McN-A-343 and AHR 602 increased both the mechanical responses and the transmitter overflow evoked by electrical stimulation of the sympathetic nerves (SNS) but inhibi…

Aspects typo-chronologiques et archéométriques de la céramique africaine sur le territoire de Cignana (Naro, AG, Sicile)

2017

Ce projet de recherche se fonde sur une étude typologique et archéométrique des matériaux d’époque romaine-impériale collectés pendant les prospections, surtout les céramiques africaines importées en Sicile entre la fin du Ier et le VIIe siècle apr. J.C. On ne va pas se concentrer sur une seule classe de céramique mais on va analyser globalement tous les objets manufacturés (amphores, sigillées, vaisselles culinaires, communes, lampes) en adoptant une approche diachronique correspondant à l’entière période de circulation de ces céramiques. L’objectif est de reconstruire les contacts économiques entre les deux provinces et individualiser l’origine des différentes productions. Nous allons ess…

Thalamic Network Oscillations Synchronize Ontogenetic Columns in the Newborn Rat Barrel Cortex

2013

Neocortical areas are organized in columns, which form the basic structural and functional modules of intracortical information processing. Using voltage-sensitive dye imaging and simultaneous multi-channel extracellular recordings in the barrel cortex of newborn rats in vivo, we found that spontaneously occurring and whisker stimulation-induced gamma bursts followed by longer lasting spindle bursts were topographically organized in functional cortical columns already at the day of birth. Gamma bursts synchronized a cortical network of 300-400 µm in diameter and were coherent with gamma activity recorded simultaneously in the thalamic ventral posterior medial (VPM) nucleus. Cortical gamma b…

Prepulse Inhibition of the Startle Reflex as a Predictor of Vulnerability to Develop Locomotor Sensitization to Cocaine

2020

Prepulse inhibition (PPI) of the startle reflex is a measure of sensory-motor synchronization. A deficit in PPI has been observed in psychiatric patients, especially those with schizophrenia and vulnerable subjects, since the neural bases of this disorder are also involved in the regulation of PPI. Recently, we have reported that baseline PPI levels in mice can predict their sensitivity to the conditioned reinforcing effects of cocaine in the conditioned place preference (CPP) paradigm. Mice with a low PPI presented a lower sensitivity to the conditioned rewarding effects of cocaine; however, once they acquired conditioned preference with a higher dose of the drug, a more persistent associa…

El comportamiento de Cajas de Ahorros y cooperativas de crédito españolas frente a los fines sociales: La obra benéfico-social y el Fondo de Educació…

2005

Cajas de ahorros y cooperativas de crédito, respondiendo a su objeto social y a los principios que les guían, dotan anualmente a Obra benéfico Social y a Fondo de Educación y Promoción Cooperativa, respectivamente, una parte de sus resultados. Ello, lejos de interferir en su competitividad en el mercado, como ha puesto de relieve su comportamiento en el sector financiero en las últimas dos décadas, responde a las virtudes propias de las entidades de economía social y contribuye a aumentar la confianza depositada hacia ellas por los agentes económicos, en la que reside la viabilidad de las empresas. En la presente comunicación, tras presentar las características de ambas ins- tituciones y se…
