  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...

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...

CD47 is a ligand of the inhibitory receptor, signal regulatory protein (SIRP)alpha, and its interaction with SIRPalpha on macrophages prevents phagocytosis of autologous hematopoietic cells. CD47-SIRPalpha signaling also regulates dendritic cell (DC) endocytosis, activation, and maturation. In this study, we show that CD47 expression on donor cells plays an important role in suppression of allo...

Recently, there has been considerable debate on redefining Indian Standard Time (IST). The suggestions include splitting the country into two timezones, while perhaps introducing daylight saving time (DST). We argue that the IST should remain unchanged. The arguments are centred around India’s geography, nation building and practical concerns. The most compelling reason offered in favour of a n...

OBJECTIVE We evaluated the impact of an automated decision support tool (DST) on clinicians' ability to identify glycemic abnormalities in structured self-monitoring of blood glucose (SMBG) data and then make appropriate therapeutic changes based on the glycemic patterns observed. RESEARCH DESIGN AND METHODS In this prospective, randomized, controlled, multicenter study, 288 clinicians (39.6%...
