The purpose of this study was to evaluate and compare the microleakage and marginal discrepancy of ceramic crown-copings fabricated by three different CAD/CAM systems. Material and methods: Thirty extracted premolars were prepared for complete allceramic crowns with: total convergence 10-degree, 2 mm occlusal reduction, 4.5 mm height, 1.3 mm circular reduction and chamfer marginal preparation. ...

From different plant parts of Calotropis species (C. gigantea and C. procera), various classes of compounds such as oxypregnanes, terpenoids, sterols, cardenolides and flavonoids have been isolated. Of these compounds, the cardenolides stand out as many of them have anticancer properties. Cardenolides are C23 steroids with a five-membered unsaturated butyrolactone ring consisting of a steroid n...

Investigations have been carried out on proteolytic activities of four laticiferous plants, viz. Calotropis procera (Ait.) R. Br. (Ruie), Carica papaya Linn. (Papaya), Euphorbia nivulia Buch.-Ham. (Sabar) and Ficus carica Linn. (Anjir) using Hammerstein grade casein and skimmed milk powder. Ratio of milk clotting to proteolytic activity was highest in the latex sample of C. papaya followed by F...

In the present investigation various bioassays were conducted to evaluate the anti-termite efficacy of plant latex based formulations to control population of Indian white termite in subtropical soil. Results reveal that crude latex, its fractions and combinatorial fractions have shown very high toxicity against O. obesus. The LD50 values for different latex fractions of 24 h were in a range of...

functional response in natural enemies is affected not only by host and natural enemy characteristics but also, the application of pesticide to pest population can affected the parameters of functional response as well as efficiency of natural enemy. in this research, the side effects of two pesticides, hexaflumuron and pymetrozin and also acaricide spirodiclofen and plant extracts, caiotropis ...

Cuscuta reflexa (whole plant) and Calotropis procera (leaves) are used in folk medicine of Bangladesh to control blood sugar in patients suffering from diabetes mellitus. The hypoglycemic effects of methanol and chloroform extracts of whole plants of Cuscuta reflexa, and methanol extract of leaves of Calotropis procera were investigated in oral glucose tolerance tests in Long Evans rats and Swi...

Widely it is used medicinally, to treat boils, infected wounds and other skin problems in people. Calotropis procera is regarded as useful medicinal plant and used in folk medicine. This plant is popularly known because it produces large quantity o...

It has been shown previously that the laticifer fluid of Calotropis procera (Ait.) R.Br. is highly toxic to the egg hatching and larval development of Aedes aegypti L. In the present study, the larvicidal potential of other laticifer fluids obtained from Cryptostegia grandiflora R.Br., Plumeria rubra L. and Euphorbia tirucalli L. was evaluated. We attempted to correlate larvicidal activity with...
