The Effects Of Feliway On The Stress Of Cats During Veterinary Examination, Colleen Doonan Dec 2018

The Effects Of Feliway On The Stress Of Cats During Veterinary Examination, Colleen Doonan

Honors Theses

The purpose of this study was to examine the effects of Feliway® during veterinary examination. Feliway® contains a synthetic version of the F3 pheromone, secreted from the cheeks of Felis sylvestris catus when rubbing against objects in the environment. It is presumed to allow cats to establish a home range to feel secure. A double-blind study was conducted to address the limitations of another study that concluded Feliway® is useful for reducing stress experienced by cats during veterinary examination. The current study found that Feliway® is not useful by itself for adequate stress reduction during feline examinations. It was concluded …


Tanapox: A Potential Oncolytic Virus For The Treatment Of Cancer, Joel Marty Jun 2018

Tanapox: A Potential Oncolytic Virus For The Treatment Of Cancer, Joel Marty

Honors Theses

The National Cancer Institute defines cancer as a group of related diseases characterized by unimpeded cell division with metastatic abilities. Cells frequently mutate and potentially become cancerous, but generally these cells are cleared by the immune system. The disease state of cancer arises when the mutated cells evade the immune clearance, which indicates medical intervention is required. Current therapies most commonly utilize chemotherapy, radiation, or a combination of the two, however, alternative therapies are being developed such as immunotherapies and oncolytic viruses (OVs). OVs cause a viral infection, clearing cancerous cells through viral replication mechanisms, such as viral cytolysis, while …


The Influence Of Plant Modularity On The Defense Against Specialist Insect Herbivory, Jill Syrotchen Apr 2018

The Influence Of Plant Modularity On The Defense Against Specialist Insect Herbivory, Jill Syrotchen

Honors Theses

Little work has been done to determine the relationship between modularity and chemical defense induction against herbivory in herbaceous plant species. We investigated this topic using Asclepias syriaca, common milkweed, and one of its specialist aphid herbivores, Aphis nerii. We studied milkweeds of varying modularities growing in the prairies of Pierce Cedar Creek Institute in Hastings, MI and introduced A. nerii to the plants, monitoring growth of plants and aphid populations over time. After A. syriaca leaves and A. nerii were harvested from study sites, leaf samples from aphid and control treatments were analyzed to measure variation with degree of …


Gdf-15 As A Biomarker For Glaucoma, Caylee Pattison Apr 2018

Gdf-15 As A Biomarker For Glaucoma, Caylee Pattison

Honors Theses

Biomarkers are measurable substances in an organism that are indicative of some phenomenon. Examples of biomarkers in clinical settings are body temperature and blood pressure. Body temperature is indicative of a fever while blood pressure can be used to monitor someone’s risk of a stroke. Previous studies have investigated the possibility of there being a potential biomarker for glaucoma. One possible biomarker identified is growth differentiation factor 15 or GDF15. These studies prompted a study in our lab using a rat glaucoma model. The objective of this study was to show there is a biomarker present for the neurodegenerative disease, …
