A cohort of endogenous depressives and normal controls were studied to examine the role of DST in depressives treated with ECT. Weekly DST estimation was done and depression was assessed on HRS-D. 73.6% patients were found to be non suppressors as compared to controls in whom 16.7% were non suppressors. 60% DST positive patients showed clinical improvement while 50% DST negative did not show im...

In the standardization of versatile video coding (VVC), discrete cosine transform (DCT)-2, sine (DST)-7, and DCT-8 are regarded as primary kernels. However, DST-4 DCT-4 can also be considered kernels instead using DST-7 owing to their effectiveness in smaller resolution test sequences. To implement these different block size kernels, a considerable amount memory has allocated. Moreover, consump...

BACKGROUND Sputum samples were collected from tuberculosis patients in a high tuberculosis incidence area in the Western Cape, South Africa. The aim of this study was to evaluate the performance and time to diagnosis of a genotypic drug susceptibility testing method. METHODOLOGY During June 2000 and November 2003, a total of 1,540 samples were sent for drug susceptibility testing (DST) to the...

We describe our success in defeating the security of an RFID device known as a Digital Signature Transponder (DST). Manufactured by Texas Instruments, DST (and variant) devices help secure millions of SpeedPassTM payment transponders and automobile ignition keys. Our analysis of the DST involved three phases: 1. Reverse engineering: Starting from a rough published schematic, we determined the c...

Depression following a cerebrovascular accident is common, disabling, and treatable. However, the consequences of a stroke often render the clinical evaluation for depression misleading or difficult to interpret. These factors make a laboratory test for depression especially desirable in this population. We reviewed and evaluated the literature on the dexamethasone suppression test (DST) as a d...

BACKGROUND Early diagnosis of tuberculosis (TB) and multidrug resistant tuberculosis (MDR TB) is important for the elimination of TB. We evaluated the microscopic observation drug susceptibility (MODS) assay as a direct rapid drug susceptibility testing (DST) method for MDR-TB screening in sputum samples METHODS All adult TB suspects, who were newly presenting to Pham Ngoc Thach Hospital from...

PURPOSE A recently introduced direct drill-guiding implant surgery system features minimal tolerance of surgical instruments in the metal sleeve by using shank-modified drills and a sleeve-incorporated stereolithographic guide template. The purpose of this study was to evaluate the accuracy of this new guided surgery system in partially edentulous patients using geometric analyses. MATERIALS ...

Drug susceptibility testing (DST) is often needed in patients clinically failing tuberculosis (TB) therapy. Most studies of phenotypic direct drug susceptibility tests, such as microscopic observation drug susceptibility (MODS) tests, have been performed in patients not receiving TB treatment. The effect of ongoing TB treatment on the performance of MODS direct DST has not been previously explo...

Preclinical data suggest that chronic stress may cause cellular damage and mitochondrial dysfunction, potentially leading to the release of mitochondrial DNA (mtDNA) into the bloodstream. Major depressive disorder has been associated with an increased amount of mtDNA in leukocytes from saliva samples and blood; however, no previous studies have measured plasma levels of free-circulating mtDNA i...

The demand for reliable drug-susceptibility testing (DST) increases with the expansion of antituberculosis drug-resistance surveillance, and with the need for an appropriate treatment of multidrug-resistant tuberculosis, whose incidence gradually increases in many parts of the world. However, the reliability of DST results obtained through widely used methods does not meet acceptable levels, ex...
