The ovine sexually dimorphic nucleus (oSDN) is 2 times larger in rams than in ewes. Sexual
differentiation of the oSDN is produced by testosterone exposure during the critical period
occurring between gestational day (GD)60 and GD90 (term, 147 d). We tested the hypothesis
that testosterone acts through the androgen receptor...

This item is a powerpoint presentation of an HHMI research project conducted during the summer of 2011 by Kyle Ireton, in partnership with Dr. Fredrick Stormshak. The objective of this study was to identify whether the myristoylated alanine-rich c kinase substrate (MARCKS) protein is phosphorylated in vivo, in response to...

Oxytocin was confirmed to have an impact of the PIP2 breakdown in ovine endometrial tissue. This experiment took two groups of ovariectomized ewes (n=5) and administered a shortened estrus cycle hormone regiment. It was found that, independent of the hormone treatments, especially P4, OT caused a small increase in the...

Mastitis is a major endemic disease in dairy cows resulting in significant economic losses for the dairy industry. The peroxisome proliferator-activated receptor gamma (PPARγ) is a nuclear receptor that is able to bind and be activated by natural (e.g., fatty acids) and synthetic (e.g. thiazolidinedione) compounds. PPARγ plays important roles...
Two research projects comprise this thesis. The first project investigated modifying the hormone dosing strategy traditionally used in superovulating donor cows for an embryo collection to decrease drug costs without decreasing the number of high quality, transferable embryos recovered. The objective of this project was to evaluate the number and...
Testosterone plays an essential role in sexual differentiation of the male sheep brain. The ovine sexually dimorphic nucleus (oSDN), is 2 to 3 times larger in males than in females, and this sex difference is under the control of testosterone. The effect of testosterone on oSDN volume may result from...

The purpose of this descriptive research was twofold: 1) to
determine the expressed concerns, feelings, and needs of a selected
group of expectant fathers; and 2) to categorize those expressed
concerns, feelings, and needs into broad areas and to develop a
priority listing of those items as a basis for...
