Alignment of new tuberculosis drug regimens and drug susceptibility testing: a framework for action.
New tuberculosis drug regimens are creating new priorities for drug susceptibility testing (DST) and surveillance. To minimise turnaround time, rapid DST will need to be prioritised, but developers of these assays will need better data about the molecular mechanisms of resistance. Efforts are underway to link mutations with drug resistance and to develop strain collections to enable assessment ...
Several systematic studies have evaluated serial dexamethasone suppression tests (DST) in patients with major depression who were treated with antidepressant medications. DST changes were noted to parallel clinical improvement in most recovering patients. If serial DSTs are a valid state-related correlate of depressive pathophysiology, all types of effective antidepressant treatment should resu...
Over the past 10 years, the Peruvian National Tuberculosis (TB) Program, the National Reference Laboratory (NRL), Socios en Salud, and US partners have worked to strengthen the national TB laboratory network to support treatment of multidrug-resistant TB. We review key lessons of this experience. The preparation phase involved establishing criteria for drug susceptibility testing (DST), selecti...
Severe storms (Dst) and Forbush decreases (FD) during cycle 23 showed that maximum negative Dst magnitudes usually occurred almost simultaneously with the maximum negative values of the Bz component of interplanetary magnetic field B, but the maximum magnitudes of negative Dst and Bz were poorly correlated (+0.28). A parameter Bz(CP) was calculated (cumulative partial Bz) as sum of the hourly n...
Background: Yearly thousands workers throughout the world, particularly in developing country are involved in work-related accidents resulting work force disability and eventually, costing a lot for industries. Recent researches show that transition into and out of DST (Day Light Saving Time) plan causes imbalance circadian rhythm and may lead to sleep disorders. Sleep deprivation may have ne...
Abstract: In paper two types of the discrete cosine (and sine) transforms (DCT/DST) are analyzed. These transforms are useful for many applications. It is shown that if an operator, connected with the Discrete Fourier Transform (DFT), is referred to an appropriate basis it takes block-diagonal form. These blocks coincide with DCT-2/DST-2 for even dimensions of the signals’ space and with DCT6/D...
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...
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...
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...
