This paper has two main objectives. The first is to provide an overview of the CDT annotation design with special emphasis on the modeling of the interface between syntactic and morphological structure. Against this background, the second objective is to explain the basic fundamentals of how CDT is marked-up with semantic relations in accordance with the dependency principles governing the anno...

Several environmental factors regulate the expression of virulence genes under certain conditions and the expression of bacterial virulence determinants. Cytolethal distending toxin (CDT) is an important virulence determinant secreted by Campylobacter jejuni (C. jejuni), a leading cause of gastrointestinal bacterial pathogen worldwide. Therefore, the aim of the study was to investigate the effe...

AIMS To test the hypotheses that performance on a clock-drawing task (CDT) diminishes over time and that poor performance is associated with development of dementia and reduced survival. METHODS Participants in the population-based Leisure World Cohort Study were asked to complete a CDT in follow-up questionnaires mailed in 1992 and 1998. Dementia status was determined using in-person evaluat...

Carbohydrate-deficient transferrin (CDT) is a descriptive term used for a temporary change in the transferrin glycosylation profile caused by alcohol, and used as a biomarker of chronic high alcohol consumption. The use of an array of methods for measurement of CDT in various absolute or relative amounts, and sometimes covering different transferrin glycoforms, has complicated the comparability...

In the diagnosis of alcohol abuse transferrin (Tf) allelic D variants generate false-positive test results for carbohydrate-deficient transferrin (CDT) as assessed by their electrophoretic migration patterns. The predominant Tf C1 allele encodes a protein for which the most prevalent isoform has a pI of 5.4, i.e., four sialic acids and two bound ion molecules. Carriers of allele D encode Tfs wi...

BACKGROUND The need for equivalent results of routine measurement procedures for the alcohol biomarker carbohydrate-deficient transferrin (CDT) has been recognized by the IFCC. This article describes a project to harmonize CDT as conducted by an IFCC working group initiated for this purpose. METHODS We used procedures for achieving harmonization as developed by the Consortium for Harmonizatio...

BACKGROUND Carbohydrate Deficient Transferrin (CDT) is a new alcohol biomarker recently approved by the Food and Drug Administration for alcohol screening. Limited information is available on the economic benefits of alcohol biomarkers. Our objective was to conduct a cost-benefit analysis (CBA) of the CDT test in a primary care sample of patients being treated for diabetes and hypertension. M...

Stauber et al. (1995) claim in the Abstract and Discussion of their paper to have demonstrated the superior sensitivity of carbohydrate-deficient transferrin (CDT) to gamma-glutamyltransferase (gamma-GT) for the detection of alcohol abuse in patients with liver disease. This claim is, however, derived from a study of 93 patients, only 13 of whom consumed alcohol in excess. The sensitivity of CD...

BACKGROUND carbohydrate-deficient transferrin (CDT) is a marker of alcohol intake that is used for detecting or monitoring alcohol-use disorders. The introduction of a new direct immunoassay for CDT justifies reevaluation of test performance and reexamination of factors affecting test diagnostic sensitivity and specificity. METHODS individuals enrolled in twin/family studies of alcohol use an...
