Azziz again on Georgia Trend’s 100 Most Influential list

Augusta, Ga. – For the second consecutive year, Dr. Ricardo Azziz, President of Georgia Health Sciences University and CEO of Georgia Health Sciences Health System, has been named one of Georgia Trend magazine’s 100 Most Influential Georgians.

The 14th edition of “Georgia’s Power List” is published in the January 2012 edition of the magazine, which covers Georgia business, politics and economic development. It’s also available online at http://www.georgiatrend.com/January-2012/Georgias-Power-List/

“It’s quite an honor to be chosen. There are some really heavy hitters in this group, including Fortune 500 CEOs and our Governor, and I am humbled to be included among them again,” Azziz said.

Azziz, 53, became the eighth President of GHSU, formerly the Medical College of Georgia, in 2010. Georgia Trend credits Azziz for leading GHSU in Transformation 2020, a strategic growth plan, and for his progress in advancing the academic health center’s reputation as a world-class organization that delivers excellence in biomedical education, research and clinical services.

Mayor Deke Copenhaver is the only other Augustan to make the list.

“Individuals on the list are selected for the power and influence they wield. These are the people who affect the lives and livelihood of all Georgians in one way or another,” according to the magazine.

ASU professors help to reduce your time in waiting lines

Augusta, Ga. –  Tis’ the season for long check-out lines, but what if there was a way for companies to shorten the wait time at the cash register? In the study, Practical Insights on Pitfalls in Estimating Queue Performance, Todd Schultz and Jim Grayson, professors in Augusta State University’s Hull College of Business, analyze waiting line systems or queuing systems to help businesses speed up time at the cash register.

“As we reviewed the standard queuing formula being taught to our business students, we noticed how the answers left a lot of room for variability for waiting lines,” Schultz said. “We wanted to remove as much error as we could from these equations to provide a more accurate wait time and more practical guidance for business owners.”
“The significant estimation errors usually found in standard queuing formulas is rarely addressed, and especially in the materials developed for students and practitioners,” Grayson said. “That is why we wanted to research this topic, because it was our goal to provide information to our students that is both educational and applicable to the real world.”
With the use of the Excel spreadsheet Visual Basic for Applications program and the spreadsheet-based application Crystal Ball, Schutlz and Grayson developed over 10,000 simulation modules that would test the standard queuing formula against queuing systems or waiting line systems in various conditions.  The results from this study show how the estimated- wait time derived from the standard queuing formula may not be accurate due to factors such as the time of day a business is open or even the amount of time it takes for an employee to complete a task.
“There are times during the day when businesses are extremely busy or very slow. That is why companies must treat these estimated waiting times as averages and not actual numbers, Grayson said. “If business owners don’t take these factors into consideration, they can cause waiting line issues for their customers which could ultimately have an effect on their sales.”
Grayson received his bachelor’s degree in general engineering from the United States Military Academy. He earned a master’s degree in business administration as well as a doctoral degree in management science and operations research from the University of North Texas.
Schultz earned his bachelor’s degree in management science from the Georgia Institute of Technology and his doctoral degree in operations research from The Johns Hopkins University.

Smaller sibling protein calls the shots in cell division

AUGUSTA, Ga. – Scientists have found at least one instance when the smaller sibling gets to call the shots and cancer patients may one day benefit.

The protein Chk1 has long been known to be a checkpoint in cell development: it keeps normal cells and damaged cells from dividing until their DNA has been fully replicated or repaired. Now scientists at Georgia Health Sciences University and the California Institute of Technology have discovered a shorter form they’ve dubbed Chk1-S (“S” stands for short) that essentially neutralizes its longer sibling so cell division can proceed.

That shorter form is in higher levels in cancer cells as well as fetal tissue, both of which require accelerated cell division. But the scientists also have shown that very high levels of Chk1-S actually reduce tumor growth and prompt premature cell division and death in other cells.

“Chk1 is needed for division of all cells, even cancer cells, so if you inhibit it completely by over-expressing Chk1-S, those cells also will not grow,” said Dr. Navjotsingh Pabla, a postdoctoral fellow at Caltech. Chk1-S expression is nearly zero in normal, non-dividing cells.

These findings, published in Proceedings of the National Academy of Sciences, point toward the short form’s potential to help diagnose and/or treat cancer, they said. Chk1 inhibitors, which promote abnormal cell division – and likely cell death – to occur before DNA replication/repair is complete, already are being tested on patients.

“Chk1-S is only expressed at a time when DNA is replicated or repaired so it binds to its sibling protein, Chk1, antagonizing it so now the cell can divide,” said Dr. Zheng Dong, cell biologist at GHSU and the Charlie Norwood Veterans Affairs Medical Center in Augusta. “The question that has been hanging on for many years is: How is Chk1 regulated?”

They found that significantly increasing levels of Chk1-S induces cell division regardless of whether DNA replication or repair is complete. Incomplete DNA replication or repair can result in spontaneous cell suicide but also can result in chromosomal or genetic defects leading to cancer cell production. Additionally, cancer cells purposefully mutate to resist treatment. Pabla speculates that expression of the shorter version may be awry in cancer cells. “We are very interested in pursuing that.”

“It’s exciting to have found an important regulator of such an important protein that we think may contribute to cancer as well as its treatment,” Dong said.

Chk1 and Chk1-S are made by the same gene they are just spliced differently. One way Chk1 gets turned on is by phosphorylation, or adding phosphate, which can activate or deactivate a protein. The level of phosphorylation of Chk1 is particularly dramatic when DNA repair is needed. Chk1, in turn, works to temporarily halt the cell cycle by phosphorylating another protein. Interestingly, Chk1-S cannot bind to its sibling when Chk1 is phosphorylated. It’s known that mental retardation can result from mutation of ATR, a DNA damage-sensing protein that phosphorylates Chk1.

While the biggest burst of cell division occurs during development, it continues lifelong in areas such as the blood, skin and gastrointestinal tract where cell turnover is high. “Lots of tissues need to regenerate,” said Dong.

Dong is a Regents Professor at GHSU and a faculty member in the university’s Medical College of Georgia and College of Graduate Studies. He is a Research Career Scientist and Director of Research Development at the Charlie Norwood VA Medical Center. Pabla worked at GHSU with Dong on the study.
