The ethanol fermentation co-product corn distillers dried grains with solubles could be useful commercially as a substrate for A. niger citric acid production.”
“Introduction We aimed to devise a rating method for key frontal and temporal brain regions validated against quantitative volumetric methods and applicable to a range of dementia syndromes.
Methods Four standardised coronal MR images from 36 subjects encompassing controls Z-DEVD-FMK and cases with
Alzheimer’s disease (AD) and frontotemporal dementia (FTD) were used. After initial pilot studies, 15 regions produced good intra-and inter-rater reliability. We then validated the ratings against manual volumetry and voxel-based morphometry (VBM) and compared ratings across the subject groups.
Results Validation against both manual volumetry (for both frontal and temporal lobes), and against whole brain VBM, showed good correlation with visual ratings for the majority of the brain regions. Comparison of rating scores across disease groups showed involvement of the anterior fusiform gyrus, anterior hippocampus and temporal pole in semantic dementia, while anterior cingulate and orbitofrontal
regions were involved in behavioural variant FTD.
Conclusion This simple visual rating can be used as an alternative to highly technical methods of quantification, and may be superior when dealing with single Dinaciclib cases or small groups.”
“To examine stool specimens from children with diarrhea from Parana State, southern Brazil, for presence of STEC.
A PCR screening assay for stx genes was used to examine a loopful of confluent colonies of 306 stool samples cultures. In six (1.96%) of them, DNA fragments of the expected size were observed, and the presence of stx was confirmed by DNA sequencing. Then up to 100 single colonies from each of the six stool cultures were analyzed using the same PCR protocol. However, stx-positive colonies were found only in two of the cultures. The E. coli strains belonged to serotypes O69:H11 and O178:H19, and presented genotypes stx(1)eae ehxA and stx(1) respectively. Shiga toxin production was confirmed using the VTEC Screen
Seiken. Except ampicillin, they were susceptible to all the antimicrobials tested.
These results show find more that STEC may be an important cause of diarrhea in children of Parana State, and that they are present in low numbers in stools. The strains belonged to serotypes not commonly found associated with STEC and probably present low virulence.
These results indicate that molecular methods are required to diagnosis of STEC infections.”
“Introduction Extracranial-intracranial (EC/IC) bypass is a useful procedure for the treatment of cerebral vascular insufficiency or complex aneurysms. We explored the role of multidetector computed tomography angiography (MDCTA), instead of digital subtraction angiography (DSA), for the postoperative assessment of EC/IC bypass patency.
