In general, benzothiazole derivatives have attracted great interest due to thier pharmaceutical and biological importance. New 2-amino-6-arylbenzothiazoles were synthesized in moderate to excellent yields via Suzuki cross coupling reactions using various aryl boronic acids and aryl boronic acid pinacol esters and the antiurease and nitric oxide (NO)(More)
The paper reports works on a wireless sensor network supporting a human operator monitoring a wide area of an unstructured environment. The main objective is to develop mechanisms allowing intelligent preliminary analysis of data (captured by a large number of sensing devices, including cameras) so that the human intervention is needed only for cases(More)
BACKGROUND In 2010, an acute illness outbreak was reported in school students eating high-energy biscuits supplied by the school feeding programme in northwest Bangladesh. We investigated this outbreak to describe the illness in terms of person, place and time, develop the timeline of events, and determine the cause and community perceptions regarding the(More)
Authentication of remote users is very important for security and privacy of multimedia content that is often accessed online. Heartbeat signal has emerged as biometric modality suitable for remote authentication for its privacy and liveness property. In order to improve acceptability of this modality, we propose a method of biometric template extraction(More)
An efficient method has been developed for the synthesis of β-enaminones under solvent-free reaction conditions using PPA-SiO2 as catalyst. The reaction yields were good to excellent (up to 90%). This methodology affords high selectivity and good tolerance of a variety of different functional groups present on both aromatic and aliphatic amines. In(More)
Stroke is the most significant complication of sickle cell disease (SCD) in children with the potential for major morbidity and mortality. The recent two decades have witnessed tremendous advancements in understanding the pathophysiology of stroke, risk stratification of children and the role of timely preventative interventions. The aetiopathogenesis,(More)
The present study was designed to investigate in vivo analgesic and cytotoxicity as well as in vitro antibacterial activities of the methanol: ethylacetate (1: 9) extract of the flowers of Peltophorum pterocarpum. Analgesic activity was assayed by acetic acid induced assay method wherein the extract showed moderate activity in a dose dependent manner. In(More)
The present study was designed to investigate antibacterial, insecticidal and in vivo cytotoxic activities of the methanol: ethylacetate (1:9) extract of leaves, barks and roots of Salix tetrasperma. Antibacterial test were done against five Gram-positive and four Gram-negative bacteria. Bark extract was active against all tested microbial species and the(More)
