Experimental Studies on the Influence of Surfactants on Intestinal Absorption of Drugs Cefadroxil as model drug and sodium taurocholate as natural mo…
2011
The influence of the natural bile acid surfactant sodium taurocholate (CAS 81-24-3) on colic and duodenal (i.e. the proximal third of the small intestine) absorption of cefadroxil (CAS 50370-12-2) was studied using the in situ rat gut technique, and compared with the effect of sodium lauryl sulfate (CAS 151-21-3), the most widely used synthetic anionic surfactant. Previously, the stability, compatibility, and micelle-solubilization characteristics of taurocholate were assessed in order to correct, when necessary, the absorption results. White the passive absorption rate constants (kf, h-1) determined in colon in the presence of increasing lauryl sulfate concentrations showed an asymptotic v…
Mechanisms of Resistance to Ceftolozane/Tazobactam in Pseudomonas aeruginosa : Results of the GERPA Multicenter Study
2020
ABSTRACT Resistance mechanisms of Pseudomonas aeruginosa to ceftolozane/tazobactam (C/T) were assessed on a collection of 420 nonredundant strains nonsusceptible to ceftazidime (MIC > 8 μg/ml) and/or imipenem (>4 μg/ml), collected by 36 French hospital laboratories over a one-month period (the GERPA study). Rates of C/T resistance (MIC > 4/4 μg/ml) were equal to 10% in this population (42/420 strains), and 23.2% (26/112) among the isolates resistant to both ceftazidime and imipenem. A first group of 21 strains (50%) was found to harbor various extended-spectrum β-lactamases (1 OXA-14; 2 OXA-19; 1 OXA-35; 1 GES-9; and 3 PER-1), carbapenemases (2 GES-5; 1 IMP-8; and 8 VIM-2), or both (1 VIM-2…
Robustness of PET Radiomics Features: Impact of Co-Registration with MRI
2021
Radiomics holds great promise in the field of cancer management. However, the clinical application of radiomics has been hampered by uncertainty about the robustness of the features extracted from the images. Previous studies have reported that radiomics features are sensitive to changes in voxel size resampling and interpolation, image perturbation, or slice thickness. This study aims to observe the variability of positron emission tomography (PET) radiomics features under the impact of co-registration with magnetic resonance imaging (MRI) using the difference percentage coefficient, and the Spearman’s correlation coefficient for three groups of images: (i) original PET, (ii) PET after co-…
Sunct syndrome. Report of a case and treatment update
2015
Short-lasting unilateral neuralgiform headache attacks with conjuntival injection and tearing (SUNCT) is considered a rare trigeminal autonomic cephalgias, a group of primary headache disorders characterized by brief episodes of severe unilateral headache in the distribution territory of the trigeminal nerve, accompanied by prominent ipsilateral and cranial parasympathetic autonomic features. The present report describes a SUNCT syndrome in a 64-year-old male who had been diagnosed with trigeminal neuralgia several years ago. The patient reported stabbing pain in the orbital zone and in the left upper maxillary region, of great intensity, brief duration, and a frequency of 20-100 attacks a …

Evaluación de la técnica quirúrgica de implantación de neuroestimulador a nivel del ganglio esfenopalatino para el tratamiento de las cefaleas crónic…
2017
- Estado actual del conocimiento El ganglio esfenopalatino (GEP), situado en la fosa pterigopalatina, es una estructura anatómica compleja que ha sido reconocida como la mayor agrupación de neuronas fuera de la cavidad craneana. No posee función sensitiva, sin embargo tiene gran relación y conexiones con múltiples ramas faciales y trigeminales, por lo que se cree que interviene en la génesis y mantenimiento de dolores faciales atípicos y cefaleas unilaterales de tipo autonómico trigeminal. El GEP contiene fibras autonómicas, tanto simpáticas como parasimpáticas. Debido a ello se ha seleccionado como estructura diana en los estudios de neuroestimulación. Existen muchas técnicas intervencioni…
Evaluación de la liberación de antibióticos incorporados en cementos utilizados en artroplastia
2017
Una de las complicaciones más serias de la artroplastia se encuentra asociada con el desarrollo de una infección, que, aunque la prevalencia de sitúa entre un 0,5 y un 3%, en algunos casos tiene consecuencias devastadoras. Por ello, uno de los mayores retos en la actualidad es la prevención de infecciones cuando un paciente es sometido a una artroplastia. El uso de antibióticos cargados en cementos óseos destinados a la artroplastia podría ser una herramienta eficaz debida a sus numerosas ventajas, la mayor ventaja de este sistema de liberación deriva de que la liberación del antibiótico se realiza en biofase y por ello permite alcanzar altas concentraciones con una baja o nula toxicidad si…
Communicative english language skills improvement programme (CELSIP). Vol. 2
2019
The digital revolution of the recent years has led to new ways of learning through combining innovative and traditional methods. In order to engage our students in this new methods, we have designed a project called “Communicative English Language Skills Improvement Program” (CELSIP) so our learners will be able to achieve a higher communicative level in English through a wide range of multimedia resources as, for instance, audio-books, learning apps, educational websites, TV series, films, board games, and music. These multimodal tools are of easy access to students since the vast majority are friendly-user. Our duty through this project was to select the most useful ones for all kind of l…
