Remarkable magnetostructural coupling around the magnetic transition in CeCo0.85Fe0.15Si.

We report a detailed study of the magnetic properties of CeCo0.85Fe0.15Si under high magnetic fields (up to 16 Tesla) measuring different physical properties such as specific heat, magnetization, electrical resistivity, thermal expansion and magnetostriction.

Vascular endothelial growth factor attenuates status epilepticus-induced behavioral impairments in rats.

Vascular endothelial growth factor (VEGF) is a vascular growth factor more recently recognized as a neurotrophic factor (for review, see Storkebaum E, Lambrechts D, Carmeliet P. BioEssays 2004;26:943-54). We previously reported that endogenous VEGF protein is dramatically upregulated after pilocarpine-induced status epilepticus in the rat, and that intra-hippocampal infusions of recombinant human VEGF significantly protected against the loss of hippocampal CA1 neurons in this model (Nicoletti JN, Shah SK, McCloskey DP, et al.

Modeling new therapies for infantile spasms.

Infantile spasms are the classical seizure type of West syndrome. Infantile spasms often herald a dismal prognosis, due to the high probability to evolve into intractable forms of epilepsies with significant cognitive deficits, especially if not adequately treated. The current therapies-high doses of adrenocorticotropic hormone, steroids, or the gamma-aminobutyric acid (GABA) transaminase inhibitor vigabatrin--are often toxic and may not always be effective.

A model of symptomatic infantile spasms syndrome.

Infantile spasms are characterized by age-specific expression of epileptic spasms and hypsarrhythmia and often result in significant cognitive impairment. Other epilepsies or autism often ensue especially in symptomatic IS (SIS). Cortical or subcortical damage, including white matter, have been implicated in the pathogenesis of SIS.
