Can Biology Define A Human Life?, Katelyn De Leon
Can Biology Define A Human Life?, Katelyn De Leon
Regis University Student Publications (comprehensive collection)
I grew up contemplating the concept of life. From my Catholic grandmother to my pediatrician mother, I always received mixed perspectives on the hot topics of abortions, vaccines, and embryo use. I found that the controversy lies in an ambiguous, mixed understanding of what constitutes a human life. From biochemical approaches to extraterrestrial life forms and spirituality there is no clear, coherent all-encompassing definition of life. However, that does not mean we can merely agree to disagree. The concept of a human life has drastic implications on our everyday lives. An insufficient definition has, and will continue to, diminish quality …

Hematopoietic stem cells (HSCs) are an integral part of modern biomedical research because they are precursors to all blood cell lineages in vertebrates. Further understanding of hematopoietic development will allow for improvements in the success of therapeutic bone marrow transplantation; which is a crucial treatment in management of both malignant and non-malignant blood disorders. Although HSC transplantation is curative for many blood disorders, finding compatible donors is difficult due to a need for immunologic compatibility. Consequently, recent research efforts have been directed towards generating HSCs for the patient, from the patient themselves through the directed differentiation of induced pluripotent stem …
Free Fatty Acid Treatment Alters Autophagy During Mouse Preimplantation Embryo Development, Zuleika C. L. Leung
Free Fatty Acid Treatment Alters Autophagy During Mouse Preimplantation Embryo Development, Zuleika C. L. Leung
Electronic Thesis and Dissertation Repository
Obesity-induced hyperlipidemia is one of the main factors for female infertility. Hyperlipidemia, specifically with high levels of palmitic acid (PA) and oleic acid (OA), interferes with preimplantation development. Autophagy is essential in early embryo development but, it is unknown whether hyperlipidemia affects autophagic mechanisms in preimplantation embryos. It was hypothesized that PA will alter autophagy in preimplantation mouse embryos and that the subsequent effects will be reversed by OA. PA impaired blastocyst development by arresting embryos at the 8-cell stage. PA also elevated early embryo autophagy by increasing autophagosome formation, decreasing maturation, and disrupting degradation. Co-treatment with OA showed developmental …
The Ethics Of Ivf, Breanna Beers
The Ethics Of Ivf, Breanna Beers
Bioethics in Faith and Practice
In vitro fertilization (IVF) has promised hope to many couples struggling with the pain of infertility. However, as with any new medical technology, the ethical implications of this procedure must be examined, particularly in light of recent events such as the birth of the first genetically modified human beings, made possible by IVF. It is crucial to examine oppositions to IVF based on principle, as well as address concerns related to adjacent issues such as the discard of unused embryos; the selection, payment, privacy, and parental rights of donors and surrogates; the importance of genetic parenthood; new combinations of gametes; …
Leukemia Inhibitory Factor (Lif): Murine Preimplantation Embryo Development, Implantation Rates, And Skeletal Development, Michael Hayes Mitchell
Leukemia Inhibitory Factor (Lif): Murine Preimplantation Embryo Development, Implantation Rates, And Skeletal Development, Michael Hayes Mitchell
Theses and Dissertations in Biomedical Sciences
Leukemia inhibitory factor (LIF) is a pleiotropic cytokine which demonstrates perplexing physiological effects. It has been demonstrated that LIF is essential for implantation in mice. Little is known relating to the manner by which LIF effects pre-implantation and post-implantation development. The objectives of this project were to determine the effects LIF on pre-implantation development, to determine the effects that it may have on implantation rates, successful pregnancy rates, and resorption rates, and to determine the effects that LIF has on the skeletal development of mice. For the embryo transfer experiments, embryos were exposed to test compounds in the transfer medium …
