Meticulous neuroradiological evaluations, including 123I-iomazenil (IMZ) single photon emission computed tomography (SPECT) and 11C-flumazenil (FMZ) positron emission tomography (PET), preoperatively disclosed epileptogenic foci in a 16-year-old boy with temporal lobe epilepsy. Interictal scalp electroencephalography showed spikes in the left temporal region. Left hippocampal sclerosis was seen...

We describe a 62-year-old woman suffering from visual hallucination due to focal status epilepticus investigated by means of Magnetic Resonance Imaging (MRI), Magnetic Resonance Angiography (MRA), Electroencephalography (EEG), and 99m Technetium ethylcysteinate dimer Single Photon Emission Computed Tomography (Tc-99m ECD SPECT). EEG showed spikes in the right parietooccipital area. MRI demonstr...

The asymmetric unit of the title compound, C(17)H(25)NO(7)S, contains two independent mol-ecules, which are enanti-omers forming a hydrogen-bonded dimer associated with two R(2) (2)(7) patterns. In each mol-ecule, one ethyl group from the two available ethyl ester functional groups is disordered. In one mol-ecule, the ethyl group of the ester function from an α-carb-oxy-lic acid is positionally...

A simple and sensitive gas chromatography (GC) method is described for the trace analysis of iodide anion (iodide) in processed seaweed as an organic derivative. The method is based on the derivatization of aqueous iodide extracted from seaweed with 2-(pentafluorophenoxy)ethyl 2-(piperidino)ethanesulfonate in toluene using tetra-n-hexylammonium bromide as a phase-transfer catalyst. The resultin...

Drosophila Toll receptors are involved in embryonic development and the immune response of adult flies. In both processes, the only known Toll receptor ligand is the human nerve growth factor-like cystine knot protein Spätzle. Here we present the crystal structure of a 1:1 (nonsignaling) complex of the full-length Toll receptor ectodomain (ECD) with the Spätzle cystine knot domain dimer. The EC...

Human epidermal growth factor receptors (HERs or ErbBs) play crucial roles in numerous cellular processes. ErbB2 is a key member of ErbB family, and its overexpression is recognized as a frequent molecular abnormality. In cancer, this overexpression correlates with aggressive disease and poor patient outcomes. Dimer-dependent phosphorylation is a key event for the signal transduction of ErbBs. ...

Several studies have proved that low-frequency transcranial magnetic stimulation (TMS) of the right dorsolateral prefrontal cortex (DLPFC) showed an antidepressant effect, although its mechanism is still not completely elucidated. The aim of the present study was to clarify the alteration in neuroanatomical function elicited by low-frequency TMS of the right DLPFC in treatment-resistant depress...

UNLABELLED The aim of this SPECT study was to determine the initial abnormality and longitudinal changes in regional cerebral blood flow (rCBF) in early Alzheimer's disease (AD) using statistical parametric mapping (SPM). METHODS rCBF was noninvasively measured using (99m)Tc-ethyl cysteinate dimer SPECT in 32 patients complaining of mild cognitive impairment, with a Mini-Mental State Examinat...

BACKGROUND Neuropsychiatric side effects of oseltamivir occur occasionally, especially in infants and young patients, but nothing is known about possible contributory factors. CASE PRESENTATION We report a case of a 15-year-old Japanese female with influenza infection who developed abnormal psychiatric symptoms after administration of standard doses of oseltamivir. She had no history of neuro...

BACKGROUND AND PURPOSE To determine the association of the apolipoprotein E (APOE) genotype and longitudinal changes of regional cerebral blood flow (rCBF) in Alzheimer's disease (AD). Previous reports have yielded conflicting results concerning this association. METHODS A retrospective cohort study was performed. rCBF was noninvasively measured using 99mTc-ethyl cysteinate dimer single-photo...
