OBJECTIVES To evaluate the ovicidal and oviposition deterrent activities of five medicinal plant extracts namely Aegle marmelos (Linn.), Limonia acidissima (Linn.), Sphaeranthus indicus (Linn.), Sphaeranthus amaranthoides (burm.f), and Chromolaena odorata (Linn.) against Culex quinquefasciatus and Aedes aegypti mosquitoes. Three solvents, namely hexane, ethyl acetate, and methanol, were used fo...

The present study on effect of imidacloprid induced oxidative stress and its amelioration was carried out at definite time periods in different groups for 90 days on 48 layer birds of above 2 months age that were divided into six groups consisting of 8 in each. The birds were divided into group 1 was control, group 2 was treated with imidacloprid @ 200 ppm in feed, group 3 was treated with vita...

Ten treatments made up experiment with: control, three concentrations gibberellic acid (GA3) 75, ...

The experiment was conducted at Department of Vegetable Science, OUAT, Bhubaneswar from 2019-2021. Stored spine gourd seeds six months old were used in this experiment. first given various physical treatments (T1: control, T2: 48 hours soaking water, T3: hot water treatment for 20 minutes + T4: scarification by sand paper T5: removal seed coat water) followed chemical (C1: GA3 100 ppm, C2: 200 ...

An experiment on “Effect of Plant growth regulators fruit yield and quality Mango (Mangifera indica L.) cv. Amrapali” was conducted at the research plot, College Horticulture, Chiplima during year 2020-21 by using Randomized Block Design with three replications ten treatments. Three concentrations NAA i.e. 10, 20 30 ppm, GA3 ppm 2,4-D were applied pea marble stage fruit. Research work held 07 y...

The acute toxic effects of a Nigerian crude oil (Egbogoro Liner II) to the mangrove oyster Crassostrea gasar were studied in bioassays. Tests were conducted over a 96-hr period after acclimatization of individuals in the laboratory, initially with a population comprising a broad size categories (11 60 mm) in range finding tests. The tests were semi-static bioassays in which the exposure media w...

The purpose of this study was to evaluate the effects of increasing levels of saponins from Quillaja saponaria on fatty acid (FA) composition and cholesterol content in muscle Longissimus dorsi of lambs. A total of 24 Barbarine lambs were assigned to four dietary treatments: control diet (C) consisting of oat hay ad libitum and 400 g of concentrate (80% barley, 17.5% soybean meal and 2.5% vitam...

The inducible isoforms of nitric oxide synthase (iNOS) and cyclooxygenase (COX-2) are overexpressed in colonic tumors of humans, as well as in colon tumors that develop in rats after the administration of the colon-specific carcinogen, azoxymethane (AOM). iNOS may regulate COX-2 production of proinflammatory prostaglandins, which are known to play a key role in colon tumor development. Experime...

The aim of this study was to examine the effect of a fluoride and xylitol containing toothpaste on the remineralization of human enamel using Quantitative Light-induced Fluorescence (QLF). Human extracted teeth were cut longitudinally into three or four parts, and artificial subsurface lesion windows (2 mm x 3 mm) were created by immersion in demineralizing solution. Each enamel sample (n = 7) ...
