This report discusses the following issues related to typing of group A streptococci (GAS): The development and use of the 5' emm variable region sequencing (emm typing) in relation to the existing serologic typing system; the designation of emm types in relation to M types; a system for validation of new emm types; criteria for validation of provisional M(More)
The C->U editing of RNA is widely found in plant and animal species. In mammals it is a discrete process confined to the editing of apolipoprotein B (apoB) mRNA in eutherians and the editing of the mitochondrial tRNA for glycine in marsupials. Here we have identified and characterised apoB mRNA editing in the American opossum Monodelphus domestica. The apoB(More)
Celera Genomics has constructed an automated computer system to support ultra high-throughput SNP genotyping that satisfies the increasing demand that disease association studies are placing on current genotyping facilities. This system consists of the seamless integration of target SNP selection, automated oligo design, in silico assay quality validation,(More)
It is well known that the FGMRES algorithm can be used as an alternative to iterative refinement and, in some instances, is successful in computing a backward stable solution when iterative refinement fails to converge. In this study, we analyse how variants of the Chebyshev algorithm can also be used to accelerate iterative refinement without loss of(More)
Intestinal apolipoprotein B mRNA is edited at nucleotide 6666 by a C to U transition resulting in a translational stop codon. The enzymatic properties of the editing activity were characterised in vitro using rat enterocyte cytosolic extract. The editing activity has no nucleotide or ion cofactor requirement. It shows substrate saturation with an apparent(More)
— We propose a new method for the measurement of the (group) delay from the RF input to the IF output of a mixer or receiver. The method is particularly convenient for measuring the change in group delay with the local oscillator tuning frequency of the receiver, since the method does not require access to, or even knowledge of, the LO signal. The method(More)
Piritrexim is a lipid-soluble inhibitor of dihydrofolate reductase (DHFR) that enters tumour cells rapidly by passive diffusion, cannot be polyglutamated, and is as effective as methotrexate in inhibiting DHFR. Bioavailability after oral dosing is approximately 75%. We performed a phase II study with oral piritrexim in non-chemotherapy pretreated patients(More)
BACKGROUND The purpose of this study was to evaluate the functional and oncological outcomes of patients treated for T3 laryngeal squamous cell carcinoma. Specifically comparing transoral laser microsurgery and radiotherapy/chemoradiotherapy treatment modalities. METHOD A retrospective review of patients treated for T3 laryngeal SCC between 2002 and 2010(More)
OBJECTIVE Sleep problems in bipolar disorder (BD) are common, but reported rates vary from 10% to 80%, depending on definitions, methodologies and management of potential confounding factors. This multicenter study seeks to address these issues and also compares BD cases with Hypersomnia as well as the more commonly investigated Insomnia and No Sleep(More)
Research in developmental psychopathology and clinical staging models has increasingly sought to identify trans-diagnostic biomarkers or neurocognitive deficits that may play a role in the onset and trajectory of mental disorders and could represent modifiable treatment targets. Less attention has been directed at the potential role of cognitive-emotional(More)
