Intraocular Pressure Sensing And Control For Glaucoma Research, Simon Antonio Bello
Intraocular Pressure Sensing And Control For Glaucoma Research, Simon Antonio Bello
USF Tampa Graduate Theses and Dissertations
Animal models of ocular hypertension are important for glaucoma research but come with experimental costs. Available methods of intraocular pressure (IOP) elevation are not always successful, the amplitude and time course of IOP changes are unpredictable and irreversible, and IOP measurement by tonometry is laborious. This dissertation focuses on the development and implementation of two novel systems for monitoring and controlling IOP without these limitations. The first device consists of a cannula implanted in the anterior chamber of the eye, a pressure sensor that continually measures IOP, and a bidirectional pump driven by control circuitry that can infuse or withdraw …
Sialylation And Cardiomyocyte Complex N -Glycosylation Protect Against Dilated Cardiomyopathy And Heart Failure, Wei Deng
USF Tampa Graduate Theses and Dissertations
Dilated cardiomyopathy (DCM) is the third most common cause of heart failure, often associated with arrhythmias and sudden cardiac death if not controlled. Metabolic and/or environmental factors, such as alcohol abuse, obesity, diabetes and Chagas disease, alter glycoprotein glycosylation, can lead to DCM. Inherited genetic disease, such as the human congenital disorders of glycosylation (CDG), causes multi-system manifestations including DCM. Non-congenital changes in glycosylation are also occurred in humans with and in animal models of DCM and heart failure. However, mechanisms responsible for glyco-dependent DCM are not understood. Here we sought to investigate the impact of sialylation and N-glycosylation …
