THE IMPACT OF MITOCHONDRIA ON PREIMPLANTATION DEVELOPMENT INTHE RHESUS MACAQUEby TIFFINI C. GIBSONAUGUST 2010Advisor: Carol Brenner, Ph.D.Major: PhysiologyDegree: Doctor of PhilosophyAssisted Reproduction Technologies (ART) have been used to treat infertility since 1790.In the centuries following, dramatic advances have been made in the field of infertility researchthrough the employment of a variety of species. Despite these advances, determination of oocyteand embryo quality remains largely subjective. Ascertainment of methods to measure oocyteand embryo quality to improve selection in ART clinics and increase pregnancy success rates isimperative. These methods are only possible with a more comprehensive understanding of thecellular and molecular properties of oocytes and preimplantation embryos. A key component ofall cells, including oocytes and embryos, is the mitochondrion, which produces energy andmaintains its own DNA for encoding proteins necessary for energy production. Defects in either the proteins responsible for energy production, the mitochondrial DNA (mtDNA) genome, orother contributing factors can lead to loss of oocyte competence and embryo quality. Humanoocytes and embryos would be the optimal material to use for performing studies on preimplantation development. However, practical and ethical constraints prevent the use ofhuman material for intensive, potentially terminal studies; thus, compelling researchers to find and use suitable animal models instead. The non-human primate (NHP) is the most befitting

Diagnosis and surgical management of an intraocular foreign body secondary to ballistic wound in a Rhesus macaque (Macaca mulatta)

Background: Intraocular foreign bodies (IOFBs) such as air gun pellet is a rare finding in wild animals like Rhesus macaque (Macaca mulatta). The purpose of the present scientific report is to describe the surgical retrieval of IOFB secondary to ballistic wound in a wild Rhesus macaque. Case description: A juvenile female wild Rhesus macaque was brought with the history of swollen and inflamed ...

Myocardial Infarction in a Rhesus Monkey

Myocardial necrosis can be result from a number of causes including nutritional deficiencies, chemical and plant toxins, ischemia and metabolic disorder. The outcome of myocardial necrosis varies depending on the extent of the damage (Donald 2001, Jubb 1993, Radostits 1994, Vanvaleet 1986). Myocardial infarction without demonstrable of atherosclerosis were reported in a rhesus macaque (Gonder 1...

The Effect of Electrical Fields from High-Voltage Transmission Line on Cognitive Changes in Male Rhesus Macaque Monkeys: A Biological and Anatomical Study Using MRI Case Report Study

Living near high-voltage power lines and exposure to high-frequency electromagnetic fields (EMFs) is a potential serious hazard to animal and human health. The present study was carried out to evaluate the effect of high-frequency EMFs from simulated high-voltage electric towers on cognitive, anatomical, and biological changes in male Macaque. In this study, two Rhesus Macaque were recruited, ...

Maternal depletion of NLRP5 blocks early embryogenesis in rhesus macaque monkeys (Macaca mulatta).

BACKGROUND Genetic defects in the oocyte can lead to female infertility due to failures in early embryogenesis. NLRP5 (NLR family, Pyrin domain containing 5) is a maternal effect factor required for early embryo development beyond the 2-cell stage in mice. The NLRP5 gene is conserved in mammals. Applying RNA interference (RNAi) technique in the macaque oocyte, we studied the in vitro effect of ...

Rhesus macaque embryos derived from MI oocytes maturing after retrieval display high rates of chromosomal anomalies.

BACKGROUND Rhesus macaque and human preimplantation embryos display similar rates of chromosomal abnormalities. The aim of this study was to determine whether embryos developing from MI oocytes that mature post-retrieval display more chromosomal anomalies than those embryos that are generated from oocytes that are at MII at the time of retrieval. METHODS Rhesus macaque oocytes were obtained a...
