Hypromellose, or hydroxypropyl methylcellulose (HPMC) - has been widely used for biomedical and pharmaceutical applications due to its advantages, including that it is modifiable in terms of viscosity, and it has the ability to form thermally reversible hydrogels. The thermal gelation temperature (TGel) of a given HPMC solution strongly depends on its characteristic grade and the solution concentration. Applying certain additives can modify the TGel even further; depending on their nature and concentration. With the addition of said additives, a lower or higher TGel can be obtained. For example, the addition of sodium chloride (NaCl) reduces …

Prenatal alcohol and early life stress exposure are associated with reduced levels of BDNF in the frontal cortex. Several studies have implicated (BDNF) in frontal cortex as important contributor of learning and memory. In the present study, we look to determine whether early housing conditions could mitigate the impact of prenatal alcohol exposure on learning as well as BDNF expression in sex-specific manner in frontal cortex of mice. Compared to control, prenatal alcohol mice expresses reduced total BDNF levels and displayed reduced freezing behavior response during contextual fear conditioning in both female and male mice. Female displayed increased BDNF levels …

Acoustofluidics And Soft Materials Interfaces For Biomedical Applications, Frank A. Fencl
Biomedical Engineering ETDs
This dissertation describes fabrication of devices and other tools for biomedical applications through the integration of acoustofluidic systems with bio separation assays, instrumentation components, and soft materials interfaces. For example, we engineer a new class of transparent acoustic flow chambers ideal for optical interrogation. We demonstrate efficacy of these devices by enhancing the signal for high throughput acoustic flow cytometry, capable of robust particle focusing across multiple parallel flowing streams. We also investigate an automated sampling system to determine the parameters of transient particle stream focusing in between sample boluses and air bubbles to model a high throughput, multi-sampling acoustic …

Background: Acute Coronary Syndrome (ACS) is a leading cause of morbidity and mortality. Metabolic syndrome and obesity are major risk factors for atherosclerosis and ACS. Dysbiosis plays an important role in metabolic syndrome and obesity. Studies show a markedly increased risk of heart attacks in patients with high levels of the pro-atherogenic metabolite trimethylamine-N-Oxide (TMAO). TMAO is produced by the intestinal microbial flora through metabolism of dietary phospholipids; Gram-negative bacteria (Phylum Proteobacteria) is the major source of TMAO metabolism. Patients with obesity and metabolic syndrome have a defective intestinal tight-junctional (TJ) barrier, which allows paracellular permeation of luminal antigens such …
