Through the last half of the nineteenth century and the first part of the twentieth, no scientist more vigorously defended Darwinian theory than the German Ernst Haeckel (1834–1919). More people learned of the new ideas through his voluminous publications, translated into numerous languages, than through any other source, including Darwin’s own writings. He enraged many of his contemporaries, e...
Abstract The ER-α and β ligand bisphenol A (BPA) is used in the production of polycarbonate plastic epoxy resins. BPA presents a potential environmental challenge to both human wildlife immunity due its widespread use resulting presence surface water wastewater runoff. We observed that exposure downregulates expression neutrophil-recruiting chemokine mice (cxcl1) zebrafish (cxcl8) decreases neu...
Background & Objective: Vitrification is an effective mean for preserving embryos. During this process, expression of implanting and apoptotic genes changes and can affect the quality of embryos. In this study, the expressions of Bax and Bcl-2 as apoptotic genes and ErbB4 as implanting gene were investigated in vitrified and warmed embryos. Materials & Methods: In this study, six-eight w...
A procedure to regenerate cassava (Manihot esculenta Crantz) cultivars from Cameroon via somatic embryogenesis (SE) was developed. Shoot apical meristems and immature leaf lobes were used as explants on Murashige and Skoog (MS) basal medium containing 33 or 50 µM of the auxins Picloram (Pic), 2,4-Dichlorophenoxyacetic acid (2,4-D), Dicamba (Dic), and α-Naphthalene acetic acid. Cultivar performa...
Separase is a protease whose liberation from its inhibitory chaperone Securin triggers sister chromatid disjunction at anaphase onset in yeast by cleaving cohesin's kleisin subunit. We have created conditional knockout alleles of the mouse Separase and Securin genes. Deletion of both copies of Separase but not Securin causes embryonic lethality. Loss of Securin reduces Separase activity because...
Three basal plant tissue culture media, namely, N6, MS, and modified Y3, were compared to optimize micropropagation protocol for E. guineensis. Full strength media were used separately to regenerate plantlets directly using immature zygotic embryos (IZEs), and through somatic embryogenesis of calli obtained from IZEs. The plantlets regenerated by direct regeneration on three media were examined...
