Envenimation mortelle par morsure de serpent chez une femme enceinte

En Afrique, la prise en charge des envenimations vipérines demeure un problème majeur de santé publique avec un taux de mortalité qui reste élevé. La survenue d’une envenimation vipérine au cours de la grossesse est un événement rare, et grave du fait des conséquences maternelles et fœtales qui en découlent. Les auteurs rapportent un cas de morsure de serpent au niveau de la face chez une femme...

1895-1900 Ma LAJP 2627:Ma

A sensitive and selective liquid chromatography tandem mass spectrometry (LC–MS/MS) method for determination of meropenem in rabbit plasma was developed. After addition of triazolam as internal standard (IS), protein precipitation by acetonitrile was used in sample preparation. Chromatographic separation was achieved on a Restek Allure (TM) PFP Propyl (2.1 mm × 100 mm, 5 μm) column with acetoni...

A sensitive and simple liquid chromatography/electrospray mass spectrometry (LC-MS/MS) method for determination of gefitinib in rat plasma using one-step protein precipitation was developed. After addition of estazolam as internal standard (IS), protein precipitation by acetonitrile was used as sample preparation. Chromatographic separation was achieved on an SB-C18 (2.1 mm × 50 mm, 3.5 μm) col...

Testing for a Linear Ma Model against Threshold Ma Models

This paper investigates the (conditional) quasi-likelihood ratio test for the threshold in MA models. Under the hypothesis of no threshold, it is shown that the test statistic converges weakly to a function of the centred Gaussian process. Under local alternatives, it is shown that this test has nontrivial asymptotic power. The results are based on a new weak convergence of a linear marked empi...
