Vascular endothelial growth factor (VEGF)-dependent angiogenesis is crucial for corpus leteum formation and their functional maintenance in mammalian ovaries. The present study was designed to test the hypothesis that hypoxia-inducible factor (HIF)-1α-mediated transcriptional activation contributes to the increased expression of

A least-squares error minimization approach was adopted to assess ferric ion diffusion coefficient of Fricke-agarose gels. Ferric ion diffusion process was modeled as a Gaussian-shaped degradation kernel operating on an initial concentration distribution. Diffusion coefficient was iteratively determined by minimizing

This study examined whether iron accumulated in ferritin-producing recombinant microbes is bioavailable to rats with iron deficiency. Rats induced with iron deficiency were treated with iron preparations of ferrous ammonium sulfate, horse spleen ferritin, control yeast, and ferritin-producing recombinant yeast
