PURPOSE To evaluate the clinical benefit of using a new iterative reconstruction technique fully integrated on a standard clinical scanner and reconstruction system using a TWIST acquisition for high-resolution dynamic three-dimensional contrast-enhanced MR angiography (CE-MRA). METHODS Low-dose, high-resolution TWIST datasets of 11 patients were reconstructed using both standard GRAPPA-based...

The 39-kDa Escherichia coli enzyme MccB catalyses a remarkable posttranslational modification of the MccA heptapeptide during the biosynthesis of microcin C7 (MccC7), a 'Trojan horse' antibiotic. The approximately 260-residue C-terminal region of MccB is homologous to ubiquitin-like protein (UBL) activating enzyme (E1) adenylation domains. Accordingly, MccB-catalysed C-terminal MccA-acyl-adenyl...

The increasing attention paid in recent years to the annual NCAA men s basketball tour nament seems due at least in part to the proliferation of o ce pools which follow tournament outcomes Such pools typically assign a point value to each game in the tournament the winner of the pool is then the person who amasses the most points Picking the winner of each indi vidual game can be done using a v...

BACKGROUND AND PURPOSE Imaging of the anterior superficial spinal cord arteries by MR angiography is hindered by their small calibers and the similarity in configuration with the anterior superficial spinal cord veins. To validate the location and spatial configuration of the great anterior radiculomedullary artery, (ie, the Adamkiewicz artery [AKA]), contrast-enhanced MR angiography (CE-MRA) w...

Multi-walled carbon nanotube (MWCNT)/TiO2 mesoporous networks can be employed as a new alternative photoanode in dye-sensitized solar cells (DSSCs). By using the MWCNT/TiO2 mesoporous as photoanodes in DSSC, we demonstrate that the MWCNT/TiO2 mesoporous photoanode is promising alternative to standard FTO/TiO2 mesoporous based DSSC due to larger specific surface area and high electrochemical act...

OBJECTIVE One of the early hallmarks of osteoarthritis (OA) is a progressive degeneration of the articular cartilage. Early diagnosis of OA-associated cartilage alterations would be beneficial for disease prevention and control, and for the development of disease-modifying treatments. However, early diagnosis is still hampered by a lack of quantifiable readouts in preclinical models. DESIGN I...

Three types of conditional lethal mutant were isolated from wild-type vesicular stomatitis virus, New Jersey serotype, after mutagenization by 5-fluorouracil: (i) conventional temperature-sensitive (ts) mutants, which form plaques at 31 C but not at 39 C; (ii) conventional host range mutants (hr CE), which grow in BHK but not in secondary chicken embryo cells; and (iii) temperature-dependent ho...

The Hurst exponent H of long range correlated series can be estimated by means of the detrending moving average (DMA) method. The computational tool, on which the algorithm is based, is the generalized variance sDMA 1⁄4 1=ðN nÞ PN i1⁄4n1⁄2yðiÞ e ynðiÞ , with e ynðiÞ 1⁄4 1=nPnk1⁄40yði kÞ being the average over the moving window n and N the dimension of the stochastic series yðiÞ. The ability to ...
