Developmental Adaptation Hypothesis : Aerobic Capacity, Submaximal Arterial Saturation And Pulmonary Volumes In Peruvian Quechua Natives, Melisa Kiyamu Tsuchiya Jan 2013

Developmental Adaptation Hypothesis : Aerobic Capacity, Submaximal Arterial Saturation And Pulmonary Volumes In Peruvian Quechua Natives, Melisa Kiyamu Tsuchiya

Legacy Theses & Dissertations (2009 - 2024)

The Quechua populations have inhabited the Andes for hundreds of generations. The ability to thrive in this hostile environment, leading an active and healthy life has generated research questions about the special phenotype of Andean highlanders compared to their sea-level counterparts, such as their higher pulmonary volumes and their outstanding work capacity in spite of the challenge of oxygen transport and delivery in hypoxia. In high altitude natives, there have been two main explanations for the origins of the aforementioned traits: genetic adaptation through natural selection and developmental adaptation through the exposure to hypoxia during growth.


The Role Of Progesterone Receptor In The Development Of The Mesocortical Dopaminergic Pathway, Jari Willing Jan 2013

The Role Of Progesterone Receptor In The Development Of The Mesocortical Dopaminergic Pathway, Jari Willing

Legacy Theses & Dissertations (2009 - 2024)

The mesocortical dopaminergic pathway, comprised of projections from the ventral tegmental area (VTA) to the prefrontal cortex (PFC), mediates many of the most complex forms of cognitive behaviors and has been associated with clinical disorders such as ADHD and schizophrenia. While this circuit continues to develop throughout much of the lifespan, there is a rapid period of maturation, early in development, in which this circuit is highly sensitive to disruption. Steroid hormone receptors are powerful transcription factors, capable of affecting a variety of neurodevelopmental processes and are expressed in many regions throughout the developing brain. Specifically, the nuclear progesterone receptor …
