BACKGROUND Nowadays natural products such as pure compounds and plant extract scan provide unlimited opportunities for new antiviral drugs. Newcastle disease virus (NDV) is one of the most important viral diseases in poultry industry. Vaccination could provide protection against NDV outbreaks, but it is not sufficient because infections by NDVs have remained frequent around the world. OBJECTI...

OBJECTIVE The aim of this study was to evaluate the antimicrobial and fluoride releasing capacity of 3 bonding materials. MATERIAL AND METHODS Thirty nine specimens with standardized surface smoothness and dimensions were prepared. The antimicrobial capacity of the materials against S. mutans, L. casei and C. albicans was evaluated by determining the percentage of growth inhibition of these m...

The in vitro fungitoxic activity of crude extracts of neem (Azadirachta indica) (A.) Juss) and pawpaw (Carica papaya) (L.) on Alternaria solani, isolated from rotting yam tubers whose pathogenicity has been proven and assessed. The organic solvent (methanol) extracts of leaves of neem and pawpaw at 20%, 40%, 60% and 80% concentrations were tested on potato dextrose agar (PDA) for activity again...

1. The effect of different doses of ouabain, an inhibitor of the sodium pump, or saline (9 g sodium chloride/1; the vehicle) on the metabolic rate of guinea-pigs weighing 500 g was measured by indirect calorimetry for 120 min. 2. Ouabain (0.02-0.07 nmol/g body-weight) decreased the oxygen consumption in a dose-related manner. When higher doses of ouabain (0.10 nmol/g body-weight or greater) wer...

In the present investigation the effect of cobalt chloride (CoCl ), ethylene biosynthesis inhibitor and 2 silver nitrate (AgNO ), ethylene perception inhibitor was studied on the seed germination of Vigna radiata. 3 While ethylene slightly promoted germination, both the inhibitors decreased the germination percentage. However, Ag was more effective in retarding germination than Co . A combined ...

The present study evaluates the acaricidal properties of crude ethanolic extract of Cassia fistula leaves for controlling Rhipicephalus (Boophilus) annulatus based on adult immersion test (AIT). The percentage of adult mortality, inhibition of fecundity and hatching of ova laid were studied at different concentrations of the extract ranging from 50 to 100 mg / ml. The results were compared usin...

Aspergillus parasiticus RCMB 002001 (2) producing four types of aflatoxins B1, B2, G1, and G2 was used in this study as an aflatoxin-producer. Penicillium griseofulvum, P. urticae, Paecilomyces lilacinus, Trichoderma viride, Candida utilis, Saccharomyces cerevisiae as well as a non-toxigenic strain of Aspergillus flavus were found to be able to exhibit growth on aflatoxin B1-containing medium u...

Thus in a system in uitro using rat adipose tissue, the addition of H D lipoprotein leads to an inhibition of lipolysis of ‘Intralipid’. This phenomenon could be the effect of competition between H D boprotein and substrate for enzyme association, perhaps through its apoprotein CII component, which can bind to lipoprotein b a s e . From our results the Percentage inhibition was greatest at the ...

AIM To evaluate the essential oil extract of the au Ocimum sanctum for its antibacterial and anti inflammatory efficacy. METHODS The essential oil extract was prepared in the Clevenger's apparatus. Antibacterial efficacy was tested against Enterococcus faecalis at two concentrations i.e. 100 & 50%. Bacterial growth was measured spectrophotometrically and percentage inhibition was calculated. ...

Based on previous studies on 1YET as heat shock protein (Hsp90), we explored the pharmacophoric features of geldanamycin co-cystallized in ATPase binding site of Hsp90 (1YET). The best phamacophore was selected and used as a searching tool to explore the national cancer institute (NCI) database. The captured hits were mapped on successful hypotheses and the best fitted compounds were selected. ...
