one small-scale double emulsion technique for incorporation of naja- naja oxiana venom into poly (lactide-co-glycolide) (plga) microspheres were developed and optimized. the effects of high speed homogenization on the double emulsion stability, microsphere size, entrapment efficiency and in vitro release of venom were studied. a stable double emulsion was verified by homogenization method. slow...

fusion is a developmental anomaly defined as the :union: of two normally separated tooth buds or the partial splitting of one tooth bud into two buds. depending on the stage of development, fusion may be either complete or incomplete. the significance of this particular case was that this fusion occurred in a posterior permanent mandibular tooth, while such a manifestation is more reported in m...
