This study evaluated the accuracy of marginal and internal fit between the all-ceramic crowns manufactured by a conventional double-layer computer-aided design/computer-aided manufacturing (CAD/CAM) system and a single-layer system. Ten standardized crowns were fabricated from each of these two systems: conventional double-layer CAD/CAM system (Procera) and a single-layer system (Cerec 3D). The...

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. ...

The present study aims to assess the toxic effect of latex and ethanolic leaf extract of Calotropis procera (C. procera), in comparison to abamectin, on serum biomarkers of function and histological integrity of heart and testis in male albino rats. To achieve this aim, the albino rats were separately administered 1/20 and 1/10 of LD50 of C. procera latex, ethanolic C. procera leaf extract and ...

Study was carried out to evaluate the pathological effects of parenterally administrated “Calotropis procera extracts” in rabbits. Fresh flowery buds of C. procera were collected from the District Lahore, Pakistan. Total of 35 rabbits of either sex were purchased from the animal house of University of Veterinary and Animal Sciences, Lahore. Rabbits were randomly distributed in to 3 major groups...

The Cyrtocarpa procera pulp was analysed for proximate composition and the effects of combining techniques such as addition of Potassium Sorbate (KS), modification of water activity (a ) and Heat treatment w (H) on the microbiological shelf life of C. procera pulp were evaluated during 100 days of storage at 25 C. o The experiment was laid out in a randomized 2 factorial with three replications...

The crude latex extract of Asclepias curassavica contains many proteins and exhibits strong proteolytic activity. The study was done to identify the clotting factor present in the latex of Asclepias curassavica and to analyze the thrombin like activity of the clotting factor. In this study the plant latex from Asclepias curassavica was collected and extracted the proteins. Proteolytic assays an...
