    • The Effects of Bisphenol A on Embryonic Development 

      Cooper-Roth, Tristan (Arizona State University. School of Life Sciences. Center for Biology and Society. Embryo Project Encyclopedia., 2012-05-10)
      Bisphenol A (BPA) is an organic compound that was first synthesized by Aleksandr Dianin, a Russian chemist from St. Petersburg, in 1891. The chemical nomenclature of BPA is 2,2-bis (4-hydroxyphenyl) propane. The significance ...
    • The Effects of Diethylstilbestrol on Embryonic Development 

      Cooper-Roth, Tristan (Arizona State University. School of Life Sciences. Center for Biology and Society. Embryo Project Encyclopedia., 2012-05-10)
      Estrogen plays a key role in the regulation of gene transcription. This is accomplished by its ability to act as a ligand and to bind to specific estrogen receptor (ER) molecules, such as ERα and ERβ, which act as nuclear ...
    • The Effects of Thalidomide on Embryonic Development 

      Cooper-Roth, Tristan (Arizona State University. School of Life Sciences. Center for Biology and Society. Embryo Project Encyclopedia., 2012-05-10)
      Embryogenesis is an intricate process that can easily be disrupted by means of teratogenic agents. Some of these agents target the embryonic period's "window of susceptibility," three to eight weeks after a pregnant woman's ...
    • Molecular Epigenetics and Development: Histone Conformations, DNA Methylation and Genomic Imprinting 

      Cooper-Roth, Tristan (Arizona State University. School of Life Sciences. Center for Biology and Society. Embryo Project Encyclopedia., 2012-05-10)
      Introduced by Conrad Hal Waddington in 1942, the concept of epigenetics gave scientists a new paradigm of thought concerning embryonic development, and since then has been widely applied, for instance to inheritable diseases, ...
    • Neural Tube Defects (NTD): Folic Acid and Pregnancy 

      Cooper-Roth, Tristan (Arizona State University. School of Life Sciences. Center for Biology and Society. Embryo Project Encyclopedia., 2012-05-25)
      In the US, one in 1000 births is affected by neural tube defects (NTD). A neural tube defect is a birth defect involving the malformation of body features associated with the brain and spinal cord. An NTD originates from ...
    • Niemann-Pick Disease 

      Cooper-Roth, Tristan (Arizona State University. School of Life Sciences. Center for Biology and Society. Embryo Project Encyclopedia., 2012-05-25)
      In 1914 Albert Niemann, a German pediatrician who primarily studied infant metabolism, published a description of an Ashkenazi Jewish infant with jaundice, nervous system and brain impairments, swollen lymph nodes ...
