Cover Story: Doxorubicin was effectively delivered by pH and redox dual responsive hollow nanocapsules which were prepared by stabilizing polyamidoamine dendron-poly(L-lysine) (PAMAM dendron-PLL) vesicles through the introduction of disulfide bonds between PLLs. PAMAM dendron, cross-linked PLL membrane and disulfide bond in the nanocapsules can provide a buffering effect for endosomal escape, an electrostatic barrier for doxorubicin entrapment and redox-responsive release by destabilizing nanocapsules, respectively. Eventually, the doxorubicin delivered into the cytoplasm could exhibit an effective anticancer effect on HeLa cells. View the paper.

Polypharmacy in Zoological Medicine

  • Robert P. Hunter and
  • Ramiro Isaza

Polypharmacy is a term that describes the inappropriate, concurrent use of multiple drugs in an individual patient. Zoological medicine practitioners must take approved agents (veterinary or human) and extrapolate their use to non-approved species of...

Cytochrome P450-mediated metabolism of arachidonic acid (AA) is an important pathway for the formation of eicosanoids. The ω-hydroxylation of AA generates significant levels of 20-hydroxyeicosatetraenoic acid (20-HETE) in various tissues. In the curr...
