Azelnidipine attenuates inflammatory responses, siperoxide and relevant signaling pathways induced by amyloid-beta in mouse cerebral endothelial cells
(University of Missouri--Columbia, 2014)
Alzheimer's disease (AD) is a debilitating neurodegenerative disease with no known cure. The cause and progression of AD is still unclear. Over the years, studies have shown that one of the earliest cytotoxic effects is ...
Evaluation of the antimicrobial properties and biocompatibility of polypropylene mesh conjugated with gold nanoparticles
(University of Missouri--Columbia, 2013)
Polypropylene (PP) mesh is commonly utilized as a patch for hernia repairs and for pelvic slings. However, biocompatibility and infection rates are a concern. Conjugating gold nanoparticles (AuNPs) to PP mesh may enhance ...
Detection of circulating breast cancer cells using photoacoustic flow cytometry
(University of Missouri--Columbia, 2013)
According to the American Cancer Society, more than 200,000 new cases of breast cancer are expected to be diagnosed this year. Moreover, about 40,000 women died from breast cancer last year alone. As breast cancer progresses ...
Photo-biomodulation and soybean isoflavones on amyloid-beta peptide-induced oxidative stress and inflammation
(University of Missouri--Columbia, 2013)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Alzheimer's disease (AD) is a chronic neurodegenerative disorder, and the aggregation of amyloid-[beta]-peptide (A[beta]) is recognized as one of the ...
Functional and structural modifications associated with hypertension, obesity and diabetes in the resistance vasculatureFunctional and structural modifications associated with hypertension, obesity and diabetes in the resistance vasculature
(University of Missouri--Columbia, 2014)
Cardiovascular diseases are considered the leading cause of death nowadays. Hypertension, obesity and type-2 diabetes are deemed major risk factors for the development of cardiovascular diseases. In essential hypertension, ...
Microfluidic capture of rare cells via non-cylindrical microposts in an array
(University of Missouri--Columbia, 2014)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] In recent decades, microsystems for the capture of rare cells have become exceedingly popular and important in the study of cellular mechanisms. These ...
Integration of single-cell electropermeabilization together with electrochemical measurement of quantal exocytosis on microchips
(University of Missouri--Columbia, 2013)
An electrochemical microelectrode located immediately adjacent to a single neuroendocrine cell can record spikes of amperometric current that result from quantal exocytosis of oxidizable transmitter from individual vesicles. ...
Regional heterogeneity of adventitial elastin in the arteriolar wall reflects differences in the mechanical environment
(University of Missouri--Columbia, 2011)
Adventitial elastin provides structural and mechanical support for arterioles. While elastin quantities are known in arterioles, the structure of elastin fibers and distribution of elastin throughout the vessel was unknown. ...
Electrospinning collagen and hyaluronic acid nanofiber meshes
(University of Missouri--Columbia, 2011)
Osteoporosis is a worldwide burden affecting over 200 million people. There are many risk factors associated with osteoporosis, but they all lead to decreased bone strength and an increased chance of bone fracture. The ...
Photoacoustic detection and spectral analysis of hemozoin in human leukocytes as an early indicator of malaria infection
(University of Missouri--Columbia, 2011)
Malaria is a blood borne infection affecting hundreds of millions of people worldwide. Usually, malaria is diagnosed only after a patient presents symptoms, including high fever, nausea, and, in advanced cases, coma and ...
Characterizing optical properties in fibrous tissues
(University of Missouri--Columbia, 2011)
Optical methods are promising for non-invasive tissue characterization. Biological tissues can be classified into isotropic tissues and anisotropic tissues. The optical properties of isotropic tissues such as adipose tissue ...
