BACKGROUND & OBJECTIVES Intravenous device (IVD) associated nosocomial blood stream infections due to staphylococci are major cause of morbidity and mortality. The present study was carried out to assess the frequency of staphylococcal IVD associated infections in a paediatric ward of a tertiary case hospital. Prevalence of resistance to commonly used(More)
BACKGROUND & OBJECTIVES Randomized controlled trials in developed countries have reported benefits of Lactobacillus GG (LGG) in the treatment of acute watery diarrhoea, but there is paucity of such data from India. The study was aimed to evaluate the efficacy and safety of Lactobacillus GG in the treatment of acute diarrhoea in children from a semi-urban(More)
BACKGROUND & OBJECTIVES All colonizing and invasive staphylococcal isolates may not produce biofilm but may turn biofilm producers in certain situations due to change in environmental factors. This study was done to test the hypothesis that non biofilm producing clinical staphylococci isolates turn biofilm producers in presence of sodium chloride (isotonic)(More)
For fine-grained sentiment analysis, we need to go beyond zero-one polarity and find a way to compare adjectives that share a common semantic property. In this paper, we present a semi-supervised approach to assign intensity levels to adjectives , viz. high, medium and low, where adjectives are compared when they belong to the same semantic category. For(More)
Nitrilases are enzymes with varied applications preferably used in preparation of industrially important compounds as well as in bioremediation processes. The production of enzymes is influenced by medium compositions as some of the constituents of medium directly affect the enzyme synthesis. In the present study, the components of the medium are optimized(More)
Nicotinic acid also known as niacin (Vitamin B3) is widely used in the food, pharmaceutical and biochemical industries. The derivatives of nicotinic acid (NAD and NADH) are playing essential roles in energy metabolism in living cells. Biological route for production of nicotinic acid is gaining more importance over chemical route as the chemical conversion(More)
