TO THE EDITOR—We read the metaanalysis by Bastos et al recently published in Clinical Infectious Diseases [1]. Because of our interest in the association of drug susceptibility testing (DST) results for firstand second-line drugs with treatment outcomes in patients with multidrugresistant (MDR) tuberculosis and extensively drug-resistant (XDR) tuberculosis, we carefully read the entire article....

Although the Dexamethasone Suppression Test (DST) was originally proposed as a specific marker for major depressive disorder (Carroll et al. 1981), several recent studies have reported high rates of DST nonsuppression in schizophrenic patients, ranging from 22% to 73%. DST nonsuppression in schizophrenia has been attributed to depressive symptomatology (Munro et al. 1983), negative symptomatolo...

[1] We test the hypothesis that abrupt cessation of solar wind driving results in a different recovery profile for Dst than does a slow cessation. The difference arises when abrupt cessation of convection causes a large portion of the asymmetric ring current to be trapped, whereas continued, weakened convection permits a rapid initial loss of ring current particles through the dayside magnetopa...

The importance of the Dempster-Shafer theory (DST) for modeling and propagating uncertainty has grown in the recent past. An obstacle for wider application of this theory in industrial practice is the lack of software support for analysts. The few tools available depend on floating point arithmetic and do not consider the inherently interval-based nature of the DST to the full extent. Therefore...

In this paper, we review recent applications of Dempster-Shafer theory (DST) of belief functions to auditing and business decision-making. We show how DST can better map uncertainties in the application domains than Bayesian theory of probabilities. We review the applications in auditing around three practical problems that challenge the effective application of DST, namely, hierarchical eviden...

A new regulatory pathway involved in plant response to oxidative stress was revealed using the iron-induced Arabidopsis ferritin AtFER1 as a model. Using pharmacological and genetic approaches, the DownSTream (DST) cis-acting element in the 3'-untranslated region of the AtFER1 mRNA was shown to be involved in the degradation of this transcript, and oxidative stress triggers this destabilization...

The discrete cosine transform (DCT) and the discrete sine transform (DST) have found wide applications in speech and image processing, as well as telecommunication signal processing for the purpose of data compression, feature extraction, image reconstruction, and ltering. In this paper, we present new recursive algorithms for the DCT and the DST. The proposed method is based on certain recursi...

BACKGROUND The implementation of rapid drug susceptibility testing (DST) is a current global priority for TB control. However, data are scarce on patient-relevant outcomes for presumptive diagnosis of drug-resistant tuberculosis (pDR-TB) evaluated under field conditions in high burden countries. METHODS Observational study of pDR-TB patients referred by primary and secondary health units. TB ...

Aims: The sensitivity and specificity of the relative disialotransferrin amount (%DST), considered the primary single target for measurement of the alcohol biomarker carbohydrate-deficient transferrin (CDT), were compared with the absolute CDT amount determined by the CDTect assay and with GGT and AST. Methods: Serum samples (n = 1387) were collected within the WHO/ISBRA Study on State and Trai...
