The Effect Of Moderate Exercise On Folliculogenesis, Cortisol, Estradiol And Luteinizing Hormone In Mares, Dale Kelley
The Effect Of Moderate Exercise On Folliculogenesis, Cortisol, Estradiol And Luteinizing Hormone In Mares, Dale Kelley
All Theses
Assisted reproductive technologies allow mares to remain in training and produce offspring; however, limited data regarding the impact of exercise on folliculogenesis exists. Mares in training are reported to have reduced embryo recovery rates and ovulated smaller follicles. The objectives of this study are to evaluate the effect of exercise on folliculogenesis using ultrasound technology. Additionally, cortisol, luteinizing hormone (LH), follicle stimulating hormone (FSH) and estradiol concentrations in mares were evaluated. The exercise period was from April to September 2008 at Latitude: 34¡ 41' 1' N. Thirteen horses were assigned to Exercise (n=6) or Control group (n=7). Mares were exercised …
The Manipulation Of Apical Dendritic Plasticity And The Consequences For The Effects Of Chronic Stress, Trudy Mccall
The Manipulation Of Apical Dendritic Plasticity And The Consequences For The Effects Of Chronic Stress, Trudy Mccall
Student Theses and Dissertations
Pyramidal cell apical dendrites in region CA3 of the hippocampus of male rats collapse in size and complexity following chronic stress. These dendrites return to control sizes with a recovery period. This suggests that dendritic remodeling can function as a protective response mechanism, protecting the region from exposure to the increased amounts of excitatory amino acid released in stress. If this is the case, then a situation in which remodeling is prevented during stress should be more damaging to the long-term survival of the organism. To examine this, animals were treated with endo N, an enzyme that cleaves PSA from …
