Treating Cardiovascular Disease with Ultrasound<\/h2>\n\n\n\n

Cardiovascular disease is historically the leading killer in the United States and a healthcare budget buster. A new treatment for one of its primary causes could help lower both those statistics.<\/p>\n\n\n\n

Nebraska\u2019s Ryan Pedrigi received a $543,000 CAREER award to explore a targeted, noninvasive treatment for atherosclerosis, which is plaque buildup in the inner lining of arteries.<\/p>\n\n\n\n

Atherosclerosis currently is treated with statin drugs or stents. Statins don\u2019t target the diseased artery, while stents are invasive and pose serious risks to patients.<\/p>\n\n\n\n

Pedrigi, assistant professor of mechanical and materials engineering, envisions treating diseased arteries with ultrasound pulses, stimulating a cellular response that could reduce plaque buildup and prevent further accumulation.<\/p>\n\n\n\n

He will start by studying how endothelial cells \u2014 the cells that form the inner lining of arteries \u2014 respond to low-intensity pulsed ultrasound. He hopes to identify the ideal ultrasound parameters for combating atherosclerosis. <\/p>\n\n\n\n

For the project\u2019s education component, Pedrigi aims to attract more women and other students from underrepresented groups to mechanical engineering.<\/p>\n\n\n\n

Probing How Nanomaterials Dissolve<\/h2>\n\n\n\n

Understanding how nano-crystals dissolve in water could lead to nanomaterials with improved stability and more controllable chemical activity. <\/p>\n\n\n\n

Nebraska\u2019s Vitaly Alexandrov, assistant professor of chemical and biomolecular engineering, aims to advance basic understanding of these chemical processes.<\/p>\n\n\n\n

\u201cIt\u2019s well known that (nanomaterials\u2019) dissolution may play both beneficial and detrimental roles,\u201d said Alexandrov, who received a $520,244 CAREER award.<\/p>\n\n\n\n

Dissolution can aid in processing and recycling materials, but it also causes corrosion and degradation of alloys and photo-electrocatalysts and decomposition of hybrid organic-inorganic solar cells and pharmaceuticals. <\/p>\n\n\n\n

Better understanding how nanomaterials dissolve will help scientists better process and recycle the materials, identify the conditions that will enable them to drive dissolution along preferable paths and aid design of materials less prone to dissolution. Alexandrov conducts his research through the Nebraska Center for Materials and Nanoscience.<\/p>\n\n\n\n

Nanomaterials have widespread applications, including medicine, aerospace, batteries, magnets, televisions, computers, weapons and insulation.<\/p>\n\n\n\n

Transforming Plant Waste with a Microbe<\/h2>\n\n\n\n

In addition to producing lots of corn, Nebraska farmers produce lots of plant waste. Much of it goes toward ethanol, but Nebraska\u2019s Rajib Saha is studying how a bacterium could break it down for other uses.<\/p>\n\n\n\n

Saha, assistant professor of chemical and biomolecular engineering, is working with Rhodopseudomonas palustris<\/em>, a purple non-sulfur bacterium noted for its ability to switch among four different types of metabolism. That versatility makes it ideal for breaking down lignin and transforming it into two substances. One can be used to create biodegradable plastics and the other to synthesize polymers widely used in textile production.<\/p>\n\n\n\n

With a $747,855 CAREER award, Saha\u2019s team will use computational modeling and experimental approaches to understand how this organism adjusts its metabolism in response to environmental changes.<\/p>\n\n\n\n

\u201cAt the end of the day, it\u2019s built on something that is a waste in our state and is abundant in our state,\u201d Saha said.<\/p>\n\n\n\n
