Functional And Dysrhythmic Slow Waves In The Stomach - An In Silico Study, Md Ashfaq Ahmed
Functional And Dysrhythmic Slow Waves In The Stomach - An In Silico Study, Md Ashfaq Ahmed
FIU Electronic Theses and Dissertations
Peristalsis, the coordinated contraction and relaxation of the muscles of the stomach, is important for normal gastric motility and is impaired in motility disorders. Coordinated electrical depolarizations that originate and propagate within a mutually coupled network of interstitial cells of Cajal (ICC) and smooth muscle cells of the stomach wall as a slow-wave, underly peristalsis. Normally, the gastric slow-wave (GSW) oscillates with a single period and uniform rostro-caudal lag, exhibiting network entrainment. Loss of entrainment in the coupled network and the resulting impairment in slow-wave propagation is associated with various gastric motility disorders. Our study provides an enhanced understanding of …

The field of bioengineering has much promise for renewable chemical production, bioremediation, and of course medical applications. Developing new useful microorganisms is extremely time and capital intensive, typically taking 50 million USD and eight years. This is due in large part to the low throughput techniques that are characteristic of the field of metabolic engineering. Here we describe the modification of an existing synthetic biosensor to measure the pharmaceutical dopamine, and the use of a circuit simulator Cadence to predict improvements to the biosensor. This biosensor paired with directed evolution techniques could reach throughputs of 5 million cells per day …

Design And Development Of Two Component Hydrogel Ejector For Three-Dimensional Cell Growth, Thomas Dunkle, Jessica Deschamps, Connie Dam
Honors Scholar Theses
Hydrogels are useful in wound healing, drug delivery, and tissue engineering applications, but the available methods of injecting them quickly and noninvasively are limited. The medical industry does not yet have access to an all-purpose device that can quickly synthesize hydrogels of different shapes and sizes. Many synthesis procedures that have been developed result in the formation of amorphous hydrogels. While generally useful, amorphous hydrogels exhibit limited capability in tissue engineering applications, especially due to their viscous properties. This endeavor aims to modulate the appropriate gelation parameters, optimize the injection process, and create a prototype that allows for the extrusion …

Photosynthethically active radiation (PAR) is a principle environmental variable used by horticultural specialists, agronomists and ecosystem modelers to characterize the quantity and quality of light conducive to plant growth and development. Spatial distribution of PAR in a greenhouse can be quite variable and diffuse throughout the day time photoperiod, especially at low sun angles in northern regions of the United States. Four colors of reflective plastic mulches (white, red, olive, and black) were evaluated for winter-time strawberry (Fragaria × ananassa Duch.) production based on their reflectance and transmittance properties in a double-polyethylene, plastic-glazed Quonset greenhouse inNebraska. The spectral properties …

BACKGROUND: The octapeptide Angiotensin II is a key hormone that acts via its receptor AT1R in the brainstem to modulate the blood pressure control circuits and thus plays a central role in the cardiac and respiratory homeostasis. This modulation occurs via activation of a complex network of signaling proteins and transcription factors, leading to changes in levels of key genes and proteins. AT1R initiated activity in the nucleus tractus solitarius (NTS), which regulates blood pressure, has been the subject of extensive molecular analysis. But the adaptive network interactions in the NTS response to AT1R, plausibly related to the development of …
