Escherichia coli O157:H7 (EcO157) shed in cattle manure can survive for extended periods of time and intervention strategies to control this pathogen at the source are critical as produce crops are often grown in proximity to animal raising operations. This study evaluated whether neem (Azadirachta indica), known for its antimicrobial and insecticidal properties, can be used to amend manure to ...

OBJECTIVE To evaluate the efficacy of Neem (Azadirachta indica) experimental gel for the prevention of erosive wear on bovine dentin, in vitro. MATERIAL AND METHODS One hundred dentin blocks were allocated into 5 experimental groups (20 samples each): C (control group, without gel); CG (control group, only base gel); F (fluoride gel, 1.23% NaF; pH 4.1, Dentsply; Brazil); N (Neem gel, 10% neem...

Trees with larvicidal activity may be found in Thailand. We conducted this study to evaluate the efficacy and length of efficacy of Thai neem (Azadirachta siamensis) oil emulsion and an alginate bead of Thai neem oil formulation against early fourth stage Aedes aegypti larvae using a dipping test. The Thai neem oil emulsion had significantly greater larvicidal activity than the alginate bead fo...

Nimbolide was first derived from the leaves and flowers of need. Neem Azadirachtaindica is a traditional medicinal plant of the Meliaceaefamily widely distributed in Asia, Africa and other tropical parts for the world. Studies of extracts from leaves, flowers, fruits and seeds have shown promising chemo preventive and therapeutic effects in pre-clinical research [1-2]. Demonstrated that extract...

We describe the coordination model of the Neem Platform, a research test bed for Project Neem, concerned with the development of socially and culturally aware collaborative systems in a wide range of

The repellent action of neem oil was evaluated against sand flies under laboratory and field conditions. Concentrations of 2% neem oil mixed in coconut or mustard oil provided 100% protection against Phlebotomus argentipes throughout the night under field conditions; against Phlebotomus papatasi it repelled sand flies for about 7 h in the laboratory. Neem oil is an indigenous product and a low-...

From the common cold that sweeps through neighborhoods every winter to AIDS, West Nile and avian flu, viral infections are among the most challenging facing researchers around the world. Neem has traditionally been used as an antiviral, and animal and laboratory research shows promising results. While researchers still have not pinpointed how neem works, it appears that compounds in neem may ma...

BACKGROUND The search for a relatively cheap, widely available, widely accepted and effective contraceptive of plant origin; that is equally non-invasive in administration, non-hormonal in action, non-toxic and that is relatively long-acting, generated our interest in this study (in order to meet the increasing need for population control). The aim of this study was to determine the effects of ...

In the present work, an artificial neural network (ANN) model was used to study the quantitative structure retention relationship (QSRR) of retention index (RI) of some volatile compounds in natural cocoa and conched chocolate powder. Molecular structural descriptors are selected using genetic algorithm to construct the nonlinear QSRR models, kernel partial least squares PLS (KPLS) and Levenber...
