“We reviewed the medical history, EEG recordings, and developmental milestones of 19 children with speech and language dysfunction and focal epileptiform activity. Speech, language, and neuropsychological assessments and EEG recordings were performed at follow-up, and prognostic indicators Selleckchem Omipalisib were analyzed. Three patterns of language development were observed: late start and slow development, late start and deterioration/regression, and normal start and later regression/deterioration. No differences in test
results among these groups were seen, indicating a spectrum of related conditions including Landau-Kleffner syndrome and epileptic language disorder. More than half of the participants had speech and language dysfunction at follow-up. IQ levels, working memory, and processing speed were also affected. Dysfunction of auditory perception in noise was found in more than PRIMA-1MET mw half of the participants, and dysfunction of auditory attention in all. Dysfunction of communication, oral motor ability, and stuttering were noted in a few. Family history of seizures and abundant epileptiform activity indicated a worse prognosis. (C) 2010 Elsevier Inc.

“In a previous work, we examined subgap states in highly doped amorphous In-Ga-Zn-O (a-IGZO) films by hard x-ray photoelectron spectroscopy (HX-PES) and found they had subgap electronic states above the valence band maximum (VBM) with the densities > 5 x 10(20) cm(-3) and just below the Fermi level with the densities > 5 x 10(19) cm(-3) [K.

Lett. 92, 202117 (2008)]; EPZ-6438 mouse however, their electron densities (N-e > 3 x 10(19) cm(-3)) are rather high and not compatible with rational properties required for active channel layers in thin-film transistors (TFTs). In this work, we report the effects of N-e and thermal annealing on the subgap states in order to provide the data useful for actual TFTs. It was found that the low-N-e a-IGZO films had extra subgap states above VBM similar to the previous report, but their densities were as small as similar to 2.0 x 10(20) cm(-3) for the highly resistive, wet-annealed a-IGZO films. Angle-dependent HX-PES revealed that the subgap states above VBM concentrate in the surface region. The O 1s peak indicated that the wet annealing suppressed the generation of subgap states by terminating these states with -OH bonds. The subgap states below E-F were observed commonly in all the samples including ZnO, crystalline (c-) IGZO and a-IGZO.
