BACKGROUND Preserved insight into illness has been suggested to be predictive of outcome in patients with schizophrenia. We aimed to investigate the functional substrate underlying preserved insight in these patients. METHODS We recruited patients with paranoid schizophrenia and healthy controls matched for age and sex. Patients were grouped according to preserved or impaired insight into ill...

BACKGROUND In addition to occipital hypoperfusion, preserved metabolism of the posterior cingulate gyri (PCG) relative to the precunei is known as the cingulate island sign (CIS) in the patients with dementia with Lewy bodies (DLB). CIS has been detected using [(18)F]fluorodeoxyglucose positron emission tomography but not using brain perfusion single-photon emission computed tomography (SPECT)....

Landau-Kleffner syndrome (LKS) is a rare childhood disorder characterized by acquired aphasia and epilepsy. 99mTc-ECD SPECT imaging was performed in two right-handed children with LKS. A relative decrease in perfusion was found in the left frontal-temporal cortices of both patients as well as in the left and right parietal cortices of one patient with aphasia, without clinical epilepsy. The deg...

UNLABELLED This study examined the relationship between the severity of aphasia and regional cerebral perfusion on brain SPECT using statistical parametric mapping (SPM) and a statistical probabilistic anatomic map (SPAM) in patients with a striatocapsular infarction (SCI) along with the other clinical and imaging findings. METHODS The subjects were 16 right-handed Korean-speaking patients wi...

The structure of the human Toll-like receptor 3 (TLR3) ectodomain (ECD) was recently solved by x-ray crystallography, leading to a number of models concerning TLR3 function (Choe, J., Kelker, M. S., and Wilson, I. A. (2005) Science 309, 581-585; Bell, J. K., Botos, I., Hall, P. R., Askins, J., Shiloach, J., Segal, D. M., and Davies, D. R. (2005) Proc. Natl. Acad. Sci. U. S. A. 102, 10976-10980)...

Receptors for the luteotropin/human chorionogonadotropin hormone belong to the G-protein-coupled receptor family by their membrane-anchoring domains. They also possess a large extracellular domain (ECD) responsible for most of the hormone-receptor interactions. Structure-function studies identified several contacts between hormone and receptor ECD, but the precise topology of the complex is sti...

Two methods for the extraction, identification and quantification of the highest occurrence and lowest perception threshold off-flavours in fifteen different samples of Brazilian Pilsner beers were developed. For this purpose, headspace solid phase microextraction in combination with a gas chromatography coupled to a mass spectrometric detection (HS-SPME-GC-MS) as well as headspace extraction i...

introduction: 5-ht1a receptor is related with a variety of neuropsychiatric disorders. . in this study a phenolic analogue derived from dway [desmethyl way-100635 (n-(2-(1-(4-(2-methoxyphenyl)piperazinyl)-ethyl))-n-(2-pyridinyl) cyclohexanecarboxamide)] is used to design the desired structure of 5-ht1a receptor imaging agents after labeling with [99mtc (co) 3(h2o) 3] + core via dithiocarbamate ...

L-Cysteinate-intercalated CaAl-layered double hydroxide (LDH) was prepared by the co-precipitation method producing highly crystalline hydrocalumite phase with a well-pillared interlayer gallery. The obtained materials were characterized X-ray diffractometry, IR as well Raman spectroscopies. By performing interlamellar oxidation reactions peracetic acid oxidant, of cysteinate to cystinate in aq...
