Firing of place cells in the exploring rat conveys doubly coded spatial information: both the rate of spikes and their timing relative to the phase of the ongoing field theta oscillation are correlated with the location of the animal. Specifically, the firing rate of a place cell waxes and wanes, while the timing of spikes precesses monotonically as the(More)
BACKGROUND AND IMPORTANCE To present the feasibility of using the Ascent balloon, a new double-lumen remodeling balloon, for a new 2-in-1 technique allowing coiling through the lumen of the balloon without the use of an additional coiling microcatheter. Remodeling technique had enlarged the indications for endovascular treatment of intracranial aneurysm.(More)
Although tumor necrosis factor-alpha has been implicated in liver injury after both warm ischemia- and cold ischemia-reperfusion, it is unclear whether reactivity of the liver to these stimuli is similar with regard to cytokine expression. Here we compare the effects of warm and cold ischemia on tumor necrosis factor-alpha expression and test the hypothesis(More)
Kupffer cells (KC), resident macrophages of the liver, have been strongly implicated in lipopolysaccharide (LPS)-induced liver graft injury. However, our recent study showed that sizofiran (schizophyllan glucan) (SPG), which activates KC, did not influence cold ischemia-reperfusion liver injury of LPS-exposed rats. Here we investigated some mechanisms by(More)
Single cell, network and population level modeling techniques all have their scope and limits in studying neurodynamic phenomena. Illustrations are given for using all the three techniques for understanding hippocampal dynamic phenomena occurring at diierent organizational levels. Multicompart-mental modeling is used here to systemaically investigate the(More)
Background Preoperative meningioma embolization may be performed with microparticles or liquid embolic agents. The pressure cooker technique (PCT) has recently been described for the embolization of brain arteriovenous malformations (AVMs). Case We present the case of a 73-year-old woman with a large frontal interhemispheric meningioma that was successfully(More)
