Despite intensive efforts to eradicate the disease, tuberculosis continues to be a major threat to Indian society, with an estimated prevalence of 3.45 million cases in 2006. Emergence of multidrug-resistant tuberculosis has complicated eradication attempts in recent years. Incomplete and/inadequate treatment are the main causes for development of drug resistance. Directly observed therapy, sho...

BACKGROUND Tuberculosis (TB) is a major public health problem in Timor Leste; treatment adherence was identified by the National TB Control Programme (NTP) as an impediment to TB control. OBJECTIVE To identify barriers to and enabling factors for the successful implementation of the DOTS strategy in Timor Leste. METHOD Qualitative research was carried out in the two districts (one rural and...

The development and expansion of WHOs DOTS strategy was successful, with 83% of the worlds population living in countries or parts of countries covered by this strategy by the end of 2004. Treatment success in the 2003 DOTS cohort of 1.7 million patients was 82% on average, close to the 85% target. Treatment success was below average in the African Region (72%), which can be partly attributed t...

Self-movement in a structured environment induces retinal image motion called optic flow. Optic flow on one hand provides information about the direction of self-motion. On the other hand optic flow presents large field visual motion which will elicit eye movements for the purpose of image stabilization. We investigated oculomotor behavior in humans during the presentation of radial optic flow ...

BACKGROUND Directly Observed Treatment Short course (DOTS) strategy is aimed at diagnosing 70% of infectious tuberculosis (TB) and curing 85% of it. Arsi Zone of Ethiopia piloted DOTS strategy in 1992. Since then, the trend in treatment outcomes in general and at district-level in particular has not been assessed. The aim of this study was to analyse the trend in TB treatment outcomes and audit...

Carbon dots (CDs) were prepared from p -phenylenediamine, modified with trifluoroacetic acid, and dispersed in a fluoropolymer (FP) film. Unmodified CDs did not disperse well the FP film, resulting concentration quenching; whereas surface modification improved affinity between FP, homogeneous dispersion an photoluminescence quantum yield.
