Can buccal infiltration of articaine replace traditional inferior alveolar nerve block for the treatment of mandibular molars in pediatric patients?:…
2021
Background It is unclear if buccal articaine infiltration can be used as an alternative to standard inferior alveolar nerve block (IANB) for treating mandibular molars in pediatric patients. Therefore, this study aimed to pool evidence to compare the efficacy of buccal infiltration of articaine vs IANB with lignocaine for pediatric dental procedures. Material and Methods We searched the PubMed, Embase, ScienceDirect, CENTRAL, and Google Scholar databases for randomized controlled trials (RCTs) comparing the two techniques in pediatric patients and reporting the success of anesthesia and/or pain during treatment. PRISMA guidelines were followed. Results Seven RCTs were included. Pooled analy…
Spatial coherence and potential predictability of intraseasonal descriptors of the rainy season in Soudano-Sahelian Africa : application to the pearl…
2010
The aim of this thesis is twofold : (i) fill a lack of knowledge about the spatial coherence and seasonal predictability of the intraseasonal characteristics (ISC) of the soudano-sahelian rainy season. These ISC are the seasonal rainfall amount (S), the daily rainfall frequency > 1 mm (O), the daily rainfall mean intensity (I), the dates of the onset and withdrawal of the rainy season, the mean length of the dry (LDS) and/or wet spells (LWS) ; (ii) document the climate-agriculture relationship over the Niamey area based on the millet crop example.From FRIEND-AOC daily rainfall records (1950-2000) for a 136 stations-network located in Senegal, Mali, Burkina-Faso and Niger, the spatial cohere…
Direct ELISA kits as a sensitive and selective screening method for abstinence control in urine.
2011
In 2009 cutoff values of assessment criteria to testify abstinence control in order to estimate driving ability were standardized in Germany. The cutoff values are lower than required in existing guidelines like SAMHSA and there is critical discussion about detection of low concentrations by using immunoassay, especially concerning amphetamines in urine (50 ng/ml). In this study Direct ELISA kits were tested for their applicability to identify the absence of amphetamines, cannabinoids, opiates, cocaine, methadone and benzodiazepines in urine. Results were confirmed by LC/MS or GC/MS analyses. Sensitivity, specificity, predictive values (positive as well as negative) and overall misclassific…
Cross-reinstatement by cocaine and amphetamine of morphine-induced place preference in mice
2005
The cross-reinstatement by psychostimulants of a conditioned place preference (CPP) induced by morphine was evaluated in mice. In Experiment 1, we examined the effects of a single dose of cocaine and amphetamine on a previously extinguished morphine CPP. After acquisition of CPP induced by morphine (40 mg/kg), animals underwent daily extinction sessions of 15 min duration until the CPP was extinguished. Subsequently, animals received a non-contingent injection of cocaine (25 mg/kg) or amphetamine (4 mg/kg), which produced the reinstatement of the extinguished morphine-induced CPP. In Experiment 2, we evaluated the reinstating effects of several priming doses of cocaine (Experiment 2A) or am…
A green method for the determination of cocaine in illicit samples
2013
Abstract Direct determination of cocaine in untreated seized samples has been made based on diffuse reflectance measurements of the near infrared (NIR) radiation through samples contained inside standard glass vials. The method used a series of previously analyzed samples, by the reference gas chromatography method, to build a partial least squares calibration model which was validated using an independent set of samples. The use of a general model for samples containing from 11.38% till 86.44% (w/w) cocaine was based on the use of spectral ranges from 12500.7 to 10128.6, 9339.8 to 6967.7 and 5388.3 to 4597.6 cm−1 with previous first derivative and vector normalization data pre-processing a…
Nanomaterial-based cocaine aptasensors.
2015
Up to now, many different methods have been developed for detection of cocaine, but most of these methods are usually time-consuming, tedious and require special or expensive equipment. Therefore, the development of simple, sensitive and rapid detection methods is necessary. In the last decade, aptamers have been used as a new biosensor platform for detection of cocaine in different samples. Aptamers are artificial single-stranded DNA or RNA oligonucleotides capable of binding to specific molecular targets with high affinity and if integrated to nanomaterials, it may lead in precise methods for cocaine detection in the common laboratories. In this review, recent advances and applications of…
Étude des caractéristiques cliniques et biologiques des patients marocains COVID-19 avec et sans dysfonctionnement olfactif et/ou gustatif
2021
Introduction et but de l’etude L’epidemie de coronavirus-2 du syndrome respiratoire aigu severe (SRAS-CoV-2), a l’origine de la maladie a coronavirus 2019 (COVID-19), presente une menace importante et urgente pour la sante mondiale. Cette infection virale alarmante, declaree pandemique par l’OMS en fevrier 2020, a entraine des millions de patients infectes et des milliers de morts dans le monde. Au Maroc, malgre les efforts fournis par les autorites, le SRAS-CoV-2 continue de se propager et constitue un fardeau de morbidite et de mortalite. L’objectif de cette etude est de decrire les caracteristiques cliniques des patients marocains COVID-19 et d’etablir la relation entre des symptomes cli…
Bilateral Transcranial Magnetic Stimulation of the Prefrontal Cortex Reduces Cocaine Intake: A Pilot Study
2016
Background Chronic cocaine consumption is associated with a decrease in mesolimbic dopamine transmission that maintains drug intake. transcranial magnetic stimulation (TMS) is gaining reliability, a useful therapeutic tool in drug addiction, since it can modulate cortico-limbic activity resulting in reduction of drug craving. Aims In the present study, we investigated the therapeutic effect of bilateral TMS of prefrontal cortex (PFC) in reducing cocaine intake, in a sample of treatment-seeking patients with current cocaine use disorder (DSM-V). Methods Ten cocaine addicts (DSM-V) were randomly assigned to the active or sham stimulation protocol in a double-blind experimental design. Twelve …
Les exilés et l'enseignement de l'espagnol en France
2006
International audience; Au moment où la France accorde l’asile au demi million d’Espagnols qui fuient Franco, la langue espagnole n’intéressait qu’une minorité restreinte d’élèves. Au début des années cinquante, alors que l’anglais et même l’allemand connaissaient les faveurs accrues de la jeunesse, l’espagnol continuait de végéter au sein d’un système éducatif où rien n’était entrepris pour le rendre plus attractif. Au cours des années qui suivirent, l’arrivée au lycée des enfants des exilés républicains, et d’une façon plus localisée, le souvenir du rôle joué par les républicains-résistants dans la libération des certaines villes du sud, modifièrent sensiblement cette situation. Les desce…
