The incidence of aetiology-specific diarrhoea and the pathogenicity of infectious agents in a birth cohort (n=252) in rural Bangladesh were determined. Stool specimens or rectal swabs were collected from diarrhoeal cases over two years and routinely on a monthly basis. Stool samples from children with diarrhoea were compared with stool samples from children(More)
The influence of media composition on callus induction and subsequent regeneration of Rauwolfia serpentina L. Benth has been studied. High frequency (96.43%) callus induction was obtained when nodal segments from in vitro raised shoots were cultured on MS medium supplemented with 0.5 mg L(-1) BA and 2.0 mg L(-1) NAA. The callus differentiated into(More)
Forty-one strains of enteroaggregative Escherichia coli formed clumps visible as a scum at the surface of a Mueller-Hinton broth shaker culture. Sixty-one control strains of E. coli did not. Scum formation is a simple, rapid, and inexpensive test for the identification of enteroaggregative E. coli.
Electron microscopy of ruthenium red-stained ultrathin section of strains of Shigella dysenteriae type 1 grown in the Casamino Acids-yeast extract broth medium showed the presence of an extracellular slime layer. The slime appeared as a dense sheath covering bacteria. The presence of slime promoted hemagglutinating activity of the bacteria. The slime(More)
Cancer is a leading cause of death worldwide. There are a lot of cancer causing agents which are divided as physical carcinogens, chemical carcinogens and biological carcinogens. But most of the carcinogens or causes of cancer are related to our lifestyle like diet, habit, occupation, radiation and some infection, etc. Chemoprevention is highly necessary to(More)
QoS (Quality of Service) is a very intricate and widespread system which belongs to the area of priority congestions management. It is implemented by using different queuing mechanisms, which take care of arranging traffic into waiting queues. Time-sensitive traffic should have maximum possible priority provided. However, if an appropriate queuing mechanism(More)
Premature ventricular contractions (PVC) are premature heartbeats originating from the ventricles of the heart. These heart beats occur before the regular heartbeat. PVC in patients with heart diseases (heart attacks, heart failure, diseases of the heart valves) may be associated with increased risks of developing ventricular tachycardia. A technique of(More)
Many intestinal bacterial pathogens possess hemagglutinating properties, which are indicative of their adhesive properties to the intestinal mucosal surface. To understand the bacteria-mucosa interaction, 41 strains of enteroaggregative Escherichia coli (EAggEC), a recently described category of diarrheagenic E. coli, isolated mostly from children with(More)
