BACKGROUND The surgical management of deep intra-axial lesions still requires microsurgical approaches that utilize retraction of deep white matter to obtain adequate visualization. We report our experience with a new tubular retractor system, designed specifically for intracranial applications, linked with frameless neuronavigation for a cohort of(More)
One hundred autopsy eyes were examined by light microscopy. Corpora amylacea (CA) occurred in 93% of the cases. Histochemical stains showed that these deposits are composed of sulfated polysaccharides. The fine structure of CA showed delicate, straight 6 to 7 nm thick filaments best demonstrated with the Thiery stain. In three cases, electron-dense vesicles(More)
OBJECTIVE Glioblastoma (GB) is rarely found in the cerebellum. Because of its rarity, it is poorly understood if cerebellar GB (CGB) behaves similarly to supratentorial GB. Studies have been limited to case reports and small case series. A better understanding of CGB may help guide treatment strategies. METHODS Surveillance, Epidemiology and End Results(More)
This paper presents an unsupervised method for change detection and analysis of the behavior of floods using multitemporal SAR (Synthetic Aperture Radar) images. First, images were filtered using the Enhanced Frost Filter in order to reduce the effect of speckle noise. Fuzzy Clustering Means (FCM) and k-means algorithms were used for unsupervised(More)
OBJECT The object of this study was to determine the relationship between plasma taurine and subarachnoid hemorrhage (SAH) outcome. METHODS Forty patients with SAH and mild neurological deficits were included in this prospective, blinded cohort study. Plasma taurine levels were measured using high-performance liquid chromatography on admission and were(More)
— Contraintes normales et déplacement d'interface : influence de la viscoélasticité sur l'efficacité de la récupération assistée — Une des méthodes de récupération assistée du pétrole (EOR-Enhanced Oil Recovery) consiste à injecter dans les puits des solutions aqueuses de polymère pour améliorer le rapport de mobilité entre le fluide injecté et le pétrole(More)
The life-cycle of Callibia diana Stål is described and linear and geometric morphometrics are used for studying allometrics and shape changes throughout this neotropical mantid species' life-cycle. Significant changes were expected in the allometry and shape of the raptorial leg and abdomen, given the importance of hunting and reproduction. The allometric(More)
