Babesia bovis parasites present a serious and significant health concern for the beef and dairy industries in many parts of the world. Difficulties associated with the current diagnostic techniques include they are prone to human error (microscopy) or expensive and time consuming (Polymerase Chain Reaction) to perform. Little is known about the biochemical changes in blood that are associated with Babesia infections. The discovery of new biomarkers will lead to improved diagnostic outcomes for the cattle industry. Vibrational spectroscopic technologies can record a chemical snapshot of the entire organism and the surrounding cell thereby providing a phenotype of the organism …

Short-term acclimation response of individual cells of Thalassiosira weissflogii was monitored by Synchrotron FTIR imaging over the span of 75 minutes. The cells, collected from batch cultures, were maintained in a constant flow of medium, at an irradiance of 120 μmol m−2 s−1 and at 20 °C. Multiple internal reflections due to the micro fluidic channel were modeled, and showed that fringes are additive sinusoids to the pure absorption of the other components of the system. Preprocessing of the hyperspectral cube (x, y, Abs(λ)) included removing spectral fringe using an EMSC approach. Principal component analysis of the time series of …

Use Of Second Harmonic Generation (Shg) Imaging For 3-Dimensional Ultrastructural Visualization Of Muscle Repair Mechanisms, Matthew Dufner
Honors Scholar Theses
In this study, we have combined SHG imaging with various fluorescent dyes which are designed to stain nuclei and used a skeletal muscle injury and regeneration model to establish the ability of this approach to reliably and reproducibly evaluate the above nuclear parameters. By using the cobra cardiotoxin (CTX-1), which creates acute well defined injuries within the muscle, on the tibialis anterior (TA) and gastrocnemius hind limb muscles of mice, predictable and reproducible regenerative patterns (in response to acute injury) can be observed by harvesting muscle samples at specific time points during recovery. Through SHG imaging, we endeavor to document …
