Astrocyte Specific Enhancers In The Cortex And Striatum Of Mice, Mikaela Kottelich

Among glial cells, astrocytes have a prevalent influence on supporting neuronal function and overall brain health. Specifically targeting this cell type for disease treatment is an existing issue. Other cell types tend to express the desired treatment, which is not always wanted and can lead to unintended, negative consequences. Astrocytes contribute largely to maintaining the blood brain barrier, which is disrupted in Parkinson’s disease. Certain genes are thought to be the reason for this disruption, so if they can be specifically targeted in astrocytes with a specific enhancer, the disruption of the disease could be reversed. In our experiment, we …
The Accuracy Of Recreational Athletes In Self Detecting Ventilation Threshold During A Maximal Exercise Test, Andrew Biegner
The Accuracy Of Recreational Athletes In Self Detecting Ventilation Threshold During A Maximal Exercise Test, Andrew Biegner
Williams Honors College, Honors Research Projects
INTRODUCTION: Ventilatory threshold (VT) is where minute ventilation (VE) increases nonlinearly with increasing exercise intensity. Prior studies have shown that subjects can recognize VT by changes in breathing during exercise. Teaching recreational athletes to use VT as a training method could result in better quality training. PURPOSE: Determine if recreational athletes can accurately perceive changes in ventilation associated with VT during maximal exercise testing. METHODS: Subjects were recruited (n=20, age= 20.5 ± 1.7 yrs.) to participate in the study. Subjects performed a modified maximal treadmill protocol with gas analysis. Subjects indicated when they noticed a considerable change …

Here I characterized the central neuroanatomy of the Blackspotted Rockskipper, Entomacrodus striatus, native to French Polynesia. The neuroanatomy of E. striatus has not been studied prior to this paper. I used several histology and antibody staining techniques to accomplish this, including Crystal Violet, immunohistochemistry, immunofluorescence, and Bielschowsky’s Silver Nitrate staining. This paper describes the most successful techniques used, identifies major structures in the species’ neuroanatomy, and also explains why studying E. striatus is important in the future of vertebrate research.
Vapocoolant Spray’S Effect On Peripheral Inserted Venous Catheter Pain In Adult Patients, Zachary Krol, Fiona Flaherty, Ryan Williams
Vapocoolant Spray’S Effect On Peripheral Inserted Venous Catheter Pain In Adult Patients, Zachary Krol, Fiona Flaherty, Ryan Williams

Intravenous (IV) cannulation is required to administer medications and fluids to patients. In addition, it is also a recognized source of pain and anxiety in over one-half of all patients requiring IV insertion (Page & Taylor, 2010). Pain management is within nurses’ scope of practice, therefore it’s important to identify effective pain management strategies. The purpose of this study is to determine the effect that a topical vapocoolant spray has on pain in pre-operative adults during IV cannulation. The gate control theory of pain will guide this randomized, experimental study of a convenience sample of adults in an outpatient endoscopic …
