Prominent Nuclear Engineer to Discuss ‘Science and Engineering on a Fast Track’ at College of Engineering Distinguished Speaker Series November 3

Arden L. Bement Jr., David A. Ross Distinguished Professor of Nuclear Engineering at Purdue University and director of the Global Policy Research Institute, will present “Science and Engineering on a Fast Track: A Reprise of the First Decade of the Twenty-First Century at NIST and NSF” on Monday, November 3, at 3:30 p.m. in UM’s McArthur Engineering Annex, Room MEA202, as part of the College of Engineering’s Distinguished Speaker Series.

Bement will discuss how the events that occurred during the first decade of the 21st century drew in the scientific and engineering resources of the nation in many ways. The decade saw the mapping of the human genome, the building of the Atacama radio telescope array to search the far reaches of the universe, the availability of university-operated petaflop-scale computers, and the emergence of cloud computing to support the era of “big data” research, to name just a few.

Light refreshments will be served. For more information, contact Vanessa Faz at 305-284-3291 or email v.faz@miami.edu.

Overuse of Cigarette Substitutes Could Pose Risk to Bones

By Marie Diaz-Guma
and Annette Gallagher

CORAL GABLES, Fla. (Aug. 26, 2014)—Cigarette smoking kills approximately 440,000 Americans each year, according to the Centers for Disease Control and Protection. It is the leading cause of preventable death worldwide. In order to overcome this addiction, many people resort to nicotine replacement therapies.

A recent literature review study by researchers at the University of Miami suggests that small dosages of nicotine found in cigarette substitutes could be harmful to the human musculoskeletal system due to overuse. The findings are reported in the Global Journal of Medical Research.

The researchers investigated and summarized the last five years of studies in the PubMed database on the effect of nicotine on wound and skeletal healing processes in humans.

The report suggests that more information is needed on the potential effect of cigarette substitutes like electronic cigarettes (e-cigarettes), which are fairly new to the market and not regulated by the Food and Drug Administration.

“E-cigarettes are marketed as safe alternatives to cigarette smoking. However, the harms associated with their overuse have not yet been widely investigated,” said Herman S. Cheung, James L. Knight Professor in the College of Engineering and senior author of the report. “We hope to increase awareness and promote further investigations into this field.”

Interestingly, the findings show that nicotine can be beneficial at low dosages. For example, exposure to low dosages of nicotine promotes collagen production and skin wound repair. Yet at higher dosages, cells involved in the wound and skeletal healing processes actually become ineffective. That’s why overuse of nicotine replacements, which still contain small amounts of nicotine, can present a health risk. However, what constitutes a low or high dosage depends on the cell type.

The consequences of nicotine overuse are not necessarily new findings. However, the specific effects of nicotine on stem cells and the musculoskeletal system are. Stem cells are generic cells that can give rise to specific cell types in the body through a process called cell differentiation. These cells play a crucial role in tissue regeneration and healing. Any changes to their natural function can significantly alter these processes.

“It has been widely documented that smokers, compared to non-smokers, experience prolonged delays in bone healing after a bone fracture,” Cheung said. “There are many theories as to why. We believe that nicotine significantly affects the potential for stem cell proliferation, migration, and osteogenic differentiation—the potential of a cell to become a bone cell,” he said. “We think that these effects cause delays to bone healing.”

The mechanisms behind the effects of nicotine on musculoskeletal health are not fully understood. However, studies show that proteins called nicotine acetylcholine receptors (nAChRS) sit on the surface of the cells in the musculoskeletal system and act as mediators of the effects of nicotine on the cells.

Found throughout the body, micro ribonucleic acid (miRNA) molecules are instrumental in regulating the process that allows a stem cell to differentiate into a specific type of cell, like a muscle, or a bone cell. The researchers believe that when nAChRS are exposed to nicotine, they affect the expression of miRNAs. But it is not yet known if this is truly the case.

“The effect of nicotine on miRNAs is the focus of our current research,” Carballosa said. “However, the link between nicotine exposure and expression of miRNAs implies that there is a correlation between the two.”

The study is titled “Nicotine’s influence on musculoskeletal healing: A review featuring nAChRS and miRNA.” David J. Fernandez-Fidalgo, a graduate student in the Department of Biomedical Engineering, is also a co-author of the report.

Altered state: Ben Patterson, left, and Felipe Gheiman defy gravity aboard NASA’s Weightless Wonder while keeping a close eye on their experiment.

CORAL GABLES, Fla. (August 20, 2014) – About an hour into the flight, Nicolas Rongione knew he was in for the ride of his life—a free-floating trip that defied the laws of Newton. With arms and legs flailing, and no control over his body’s orientation, the University of Miami senior must have felt a lot like Alan Shepard some 53 years ago when he blasted off from Cape Canaveral aboard a Freedom 7 capsule to become the first American in space.

Faculty and Staff Support the U: Engineer Enhances Environmental—and University—Resources

Helena Solo-Gabriele

Helena Solo-Gabriele

As a teacher, researcher, role model, and donor, Helena Solo-Gabriele is making a difference in the world. “Since I was an undergraduate here in the 1980s, our University has made huge advances,” says Solo-Gabriele, professor and associate dean for research in the College of Engineering. “While the amount I give each year isn’t large, I know it’s important. As more and more of our faculty, staff, and alumni donate, our University gains important resources.”

The daughter of Cuban-born parents, Solo-Gabriele is a long-time member of the UM “family.”  Her father, Emilio Solo, earned his bachelor’s degree in mechanical engineering from the University of Miami in 1964. “He would bring our family to the UM pool, and it was always a special trip to come to the campus,” she says. Following in her father’s footsteps, she and her husband, Frank Gabriele, III, introduced their two daughters, Christina, now 19, and Elizabeth, 12, to the campus at an early age.
