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...

We have investigated the effectiveness and safety of a newly developed biological adhesive for repair of meniscal tear. The adhesive was composed of disuccinimidyl tartrate (DST) as a crosslinker and human serum albumin (HSA) as a hardener. To determine adequate concentration, bonding strength was measured using a tensiometer 5 min after applying the adhesive on the avascular zone tear of porci...

BACKGROUND AND OBJECTIVES Patients with multidrug-resistant (MDR) tuberculosis (TB) are at high risk of treatment failure. It is anticipated that early identification of MDR-TB and appropriate treatment will improve patient outcome and disease control. We evaluated the rapid detection of rifampicin resistance in previously treated TB patients, directly from acidfast bacilli (AFB)-positive sputu...

The association between abnormal Dexamethasone Suppression Test (DST) and sleep electroencephalographic (EEG) findings and depressives’ response to active drug treatment is equivocal. Recently, however, investigators have attempted to determine the relationship between these measures and response to somatic versus nonsomatic treatment. Carroll (1985) has reported that DST nonsuppressors are not...

Future NASA exploration missions to Mars, Europa, Titan, comets and asteroids are seeking to perform sampling, in-situ analysis and possibly return of material to Earth for further tests. One of the major limitations of conventional drills when sampling in low gravity environments is the need for high axial force and, as a result, heavy robotic mechanisms, which constrain mission objectives. To...

The dexamethasone suppression test (DST) was performed in 38 patients satisfying the Research Diagnostic Criteria (RDC) for cortisol, human growth hormone (hGH), prolactin, triiodothyronine (T3), thyroxine (T4) and thyroid-stimulating hormone (TSH) were determined at 4:00 p.m. before the administration of dexamethasone, whereas cortisol, hGH and TSH were determined at 4:00 p.m. the day after. A...

The purpose of this study was to evaluate the variation in plasma adrenocorticotropic hormone (ACTH) concentration and dexamethasone suppression test (DST) results with season, age, and sex in healthy, pony mares (n=15) and pony stallions (n=14) living under semiferal conditions and horse mares (n=10) living at pasture. Plasma ACTH concentrations were measured in September 2002, and in January,...

OBJECTIVE To explore both the early prediction and diagnosis of dysphagia in preterm infants as an important developmental aspect as well as the prevention of respiratory complications, we developed the simple and-easy-to-apply Dysphagia Screening Test for Preterm Infants (DST-PI) to predict supraglottic penetration and subglottic aspiration. METHODS Fifty-two infants were enrolled in a video...

Understanding thermally driven coupled hydrological, mechanical, and chemical processes in unsaturated fractured tuff is essential for evaluating the performance of the potential radioactive waste repository at Yucca Mountain, Nevada. The Drift Scale Test (DST), intended for acquiring such an understanding of these processes, has generated a huge volume of temperature and moisture redistributio...

[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...
