Ewes 5/6 dpc were injected with a gram-positive bacteria cell wall component, peptidoglycan-polysaccharide (PG-PS), to induce an innate immune system acute phase response (APR). The induction of the APR and its reactant molecules, such as cytokines and acute phase proteins (APP), were initiated to study their effects on embryonic loss. Twenty Suffolk ewes were synchronized for estrus and bred by fertile rams. At 4 dpc ewes were anesthetized and catheters were surgically placed in the …
Non-Apoptotic Roles Of Caspase-8 And Caspase-2, Brooke M. Helfer
Non-Apoptotic Roles Of Caspase-8 And Caspase-2, Brooke M. Helfer
Graduate Theses, Dissertations, and Problem Reports (ETD)
Caspases are proteolytic enzymes involved in committing apoptosis, but through the studies of knockout phenotypes in mice and Drosophila , it has been speculated that caspases might possess additional non-apoptotic functions.;We have found non-apoptotic functions for caspase-8 in both normal and tumor cell lines. Specifically, we found that caspase-8 promotes cell migration, adhesion, and Rac activation. Subsequently, we also found that caspase-8 interacts with the p85 subunit of PI3K. Accompanying stimulation of motility with epidermal growth factor the phosphorylation of caspase-8 on tyrosine-380 is induced and this phosphorylation allows for p85 interaction, cell migration, adhesion, and Rac activation. Caspase-8 also …

Neuropsychological Functioning Of College Students With Attention Deficit Hyperactivity Disorder, Melanie Ann Nuszkowski
Graduate Theses, Dissertations, and Problem Reports (ETD)
Individuals with Attention Deficit Hyperactivity Disorder (ADHD) often experience significant impairment in multiple life domains not only during childhood, but also throughout their adult lives. While there is no single litmus test for identifying ADHD, neuropsychological tests have been proposed as one means of enhancing identification of ADHD in adults. Theories of ADHD have suggested that deficits in executive functioning underlie the symptom appearance for ADHD; however, meta-analyses have suggested that non-executive functioning skills provide nearly equal discriminatory results. Given the increasing proportion of students with ADHD who are pursuing postsecondary education, the need for further research addressing the impact …
