Evaluation of zirconia bonding to veneering porcelain

Zirconium dioxide as core ceramic material for dental crowns and bridges, possess high strength, chemical stability and superior aesthetics after veneering.Veneering ceramic is considered to be the weakest part of all-ceramic restorations.The adhesion between the stringmaterial core and veneering porcelain is based on the manner in which the connec

Molecular Barriers to Zoonotic Transmission of Prions

The risks posed to human health by individual animal prion diseases cannot be determined a priori and are difficult to address empirically.The fundamental event in prion disease pathogenesis is thought to be the notions seeded conversion of normal prion protein to its pathologic isoform.We used a rapid molecular conversion assay (protein misfolding

Waking the sleeping dragon: gene expression profiling reveals adaptive strategies of the hibernating reptile Pogona vitticeps

Abstract Background Hibernation is a physiological state exploited by many animals exposed to prolonged adverse environmental conditions associated with winter.Large changes in metabolism and cellular function occur, with many stress response pathways modulated to tolerate physiological challenges that might otherwise be lethal.Many studies have so
