BACKGROUND Dentists are always looking ahead for more dimensionally stable material for accurate and successful fabrication of prosthesis in this competitive world. Arrival of newer materials and increased material market puts dentists in dilemma for selection of material. AIM The study evaluated the effect of variations in time of pour and temperature on dimensional stability of three brands...

Asthmatic patients are more subjected to continuous oxidative stress. Roosting the antioxidant defenses of asthma patient could be beneficial as it may help thwart symptoms of the lung disease and asthma. Considering these facts different plant extracts and phytoconstituents with proven anti asthmatic property had been subjected to antioxidant study at various combinations using Diphenyl Vicryl...

For past many years, strategies for the preclinical discovery and development of potential anticancer agents have been based largely upon the testing of agents in. selected animals bearing transplantable tumors. The feasibility of implementing combined in vitro/in vivo screening for selective cytotoxicity among panels of human tumor cell lines derived from a broad spectrum of human carcinomas h...

taxol is used to treatment of variety cancers including ovarian, breast, lung, head and neck carcinomas and the aids-related karposi’s carcinoma, and was originally obtained from bark of taxus brevifolia. however the amount of extracted taxol from taxus is extremely low and cannot be considered as a suitable commercial source and it has led to studies for finding new sources of taxol. in 1998, ...

Synthesis of 2’,4’-dihydroxy-3,4-dimethoxychalcone and in vitro test its sunscreen activity have been carried out. Chalcone was synthesized from 3,4-dimethoxybenzaldehyde 2,4-dihydroxyacetophenone through Claisen-Schmidt condensation. The synthesis performed by using KOH 40% under stirring at room temperature for 48 h. compounds characterized FTIR, GC-MS 1H NMR spectrometers. Further, the chalc...
