University of Utah professors Bradley R. Cairns, professor and chair of Oncological Sciences and senior director of Basic Science; Dana Carroll, distinguished professor of Biochemistry; and Christopher D. Hacon, distinguished professor of Mathematics, were raised to a high honor in science today with their election to the American Academy of Arts and Sciences. The three scientists join 225 U.S. scholars, scientists, writers, artists, as well as civic, business and philanthropic leaders, elected by the Academy, which is headquartered in Cambridge, Mass. Members of the 2017 class include winners of the Pulitzer Prize and the Wolf Prize, MacArthur Fellows, Fields Medalists, Presidential Medal of Freedom and National Medal of Arts recipients, and Academy Award, Grammy Award, Emmy Award and Tony Award winners. Bradley R. Cairns was honored for his work examining how chromatin, the structures that package chromosomal DNA, switch genes on or off. He is working to understand how changes in chromatin affect cellular mechanisms that can lead to cancer development. As an investigator at the Huntsman Cancer Institute (HCI) at the University of Utah, Cairns is using zebrafish to study genes associated with many types of cancers. Along with this latest honor, Cairns has been a Howard Hughes Medical Institute Investigator since 2000. "Dr. Cairns has made fundamental discoveries in the areas of DNA remodeling and regulation of gene expression that are influencing how we think about human development and disease," said Mary Beckerle, CEO and director of HCI. "In addition to his innovative and high-impact scientific work, Dr. Cairns is also an exceptional leader who has built a culture of excellence and collaboration at Huntsman Cancer Institute and the University of Utah. The American Academy of Arts and Sciences couldn't have chosen a better person to honor with membership in this distinguished society." Dana Carroll has been on the faculty at the U of U Health for 42 years. Starting 21 years ago, he developed the earliest of the precise genome editing platforms, zinc-finger nucleases. He has worked with ZFNs and the successor technologies, TALENs and CRISPR-Cas, all of which are being used around the world to learn the consequences of specific mutations, to improve agricultural plant and animals, and to develop treatments for human diseases. Carroll received both the 2012 Edward Novitski Prize from the Genetics Society of America and the 2014 Herbert Sober Lectureship from the American Society of Biochemistry and Molecular Biology. He also received the 2016 Distinguished Innovation and Impact Award from the University of Utah. "I am ecstatic to hear that Dr. Dana Carroll has been elected into the American Academy of Arts and Sciences," said U of U Vice President for Research Andrew Weyrich. "Dr. Carroll is a pioneer in the research community for his groundwork in genome editing platforms, which have been used effectively to modify the genomes of over 80 organisms. This is a great honor for his continuous dedication and contribution to research and science." Christopher Hacon is a scholar of algebraic geometry, the field of mathematics that studies geometric objects defined by polynomial equations. He is particularly interested in objects that exist in more than three dimensions, and he and his colleagues have applied studies of these objects to extend the "minimal model program," a foundational principle of algebraic geometry, into higher dimensions. The American Mathematical Society has lauded the work of Hacon and his colleagues as "a watershed in algebraic geometry." Hacon is a fellow of the American Mathematical Society and recipient of the 2016 EH Moore Research Article Prize, the 2015 Distinguished Scholarly and Creative Research Award from the University of Utah, the 2011 Antonio Feltrinelli Prize in Mathematics Mechanics and Applications, the 2009 Frank Nelson Cole Prize in Algebra and the 2007 Clay Research Award. "Hacon's election as a member of the AAAS stands in recognition of his towering stature as a research mathematician and his deep contributions not only to the discipline of mathematics, but also to the University of Utah," said Peter Trapa, chair of the Department of Mathematics. "It is an honor to welcome this new class of exceptional women and men as part of our distinguished membership," said Don Randel, Chair of the Academy's Board of Directors. "Their talents and expertise will enrich the life of the Academy and strengthen our capacity to spread knowledge and understanding in service to the nation."

Epilepsies are debilitating neurological disorders characterized by repeated episodes of pathological seizure activity. Absence epilepsy (AE) is a poorly understood type of seizure with an estimated 30% of affected patients failing to respond to antiepileptic drugs. Thus, novel therapies are needed for the treatment of AE. A promising cell-based therapeutic strategy is centered on transplantation of embryonic neural stem cells from the medial ganglionic eminence (MGE), which give rise to gamma-aminobutyric acidergic (GABAergic) interneurons during embyronic development. Here, we used the Stargazer (Stg) mouse model of AE to map affected loci using c-Fos immuno-histochemistry, which revealed intense seizure-induce activity in visual and somatosensory cortices. We report that transplantation of MGE cells into the primary visual cortex (V1) of Stg mice significantly reduces AE episodes and lowers mortality. Electrophysiological analysis in acute cortical slices of visual cortex demonstrated that Stg V1 neurons exhibit more pronounced increases in activity in response to a potassium-mediated excitability challenge than wildtypes (WT). The defective network activity in V1 was significantly altered following WT MGE transplantation, associating it with behavioral rescue of seizures in Stgs. Taken together, these findings present MGE grafting in the V1 as a possible clinical approach in the treatment of AE. © The Author 2014.

As the focus of forest management on many public lands shifts away from timber production and extraction to habitat, restoration, and diversity-related objectives, it is important to understand the long-term effects that previous management activities have on structure and composition to better inform current management decisions. In this paper, we analyzed 40years of growth data to quantify (1) the long-term response of yellow-poplar to thinning across an age and site quality gradient, and (2) the longevity of any growth response yellow-poplar may have to thinning throughout the southern Appalachian Mountains. Between 1960 and 1963, 134-0.1ha plots were established across an age and site quality gradient in yellow-poplar (Liriodendron tulipifera L.) stands throughout the southern Appalachian Mountains. All plots were thinned from below, with post-thinning relative density categorized into three classes: low (relative density <0.25), moderate (relative density ≥0.25 but <0.35), and high (relative density ≥0.35 but <0.60). Using plot-level annual basal area increment (BAI; cm2 yr-1) chronologies reconstructed from tree cores, average annual BAI was calculated for 10years prior to thinning (BAIpre) and each following 10year period thereafter (BAIpost).Site index and age at the time of thinning had a positive effect on BAIpost. During the first 10year period following thinning, annual BAI (at a site index=32.3m and age=43) averaged (SE) 33.7 (1.6), 26.3 (1.3), and 21.6 (1.1) cm2 yr-1 in the low, moderate, and high density classes, respectively. Significant differences between low and moderate and low and high density classes remained throughout the duration of the study. During the 10years post-thinning the ratio of BAIpost to BAIpre (RBAI) was >1.0 in 92%, 86%, and 57% of plots in the low, moderate, and high density classes, respectively indicating an overall increase in growth relative to pre-thinning growth rates. By the fourth decade post-thinning the percentage of stands containing trees that possessed RBAI values >1.0 had fallen; however trees in 71% of the plots in the low density class continued to experience growth rates greater than those prior to thinning. We conclude the increase in growth is short-lived when density is reduced to moderate and high levels whereas the response of trees to more intense thinnings is long-lasting. © 2013.

In this paper, using longitudinal data on route level monthly average weekday ridership in the entire Chicago Transit Authority (CTA) bus system from January 2002 through December 2010, we evaluate the ridership effects of the CTA real-time bus information system. This bus information system is called CTA Bus Tracker and was incrementally implemented on different CTA bus routes from August 2006 to May 2009. To take account of other factors that might affect bus ridership, we also include data on unemployment levels, gas prices, local weather conditions, transit service attributes, and socioeconomic characteristics during the study period. This combined longitudinal data source enables us to implement a quasi-experimental design with statistical controls to examine changes in monthly average weekday ridership, before and after the Bus Tracker system was implemented, on each bus route. Based on a linear mixed model, we found that the provision of Bus Tracker service does increase CTA bus ridership, although the average increase is modest. Further, the study findings suggest that there are temporal variations of the ridership effects among the routes, with the " winning" routes more likely to have the technology implemented in the later phases of the overall " roll-out" period. However, the results are less conclusive regarding geographical variations in the effects of Bus Tracker. © 2012 Elsevier Ltd.

Clinics in Liver Disease | Year: 2014
Obesity is strongly associated with the prevalence of nonalcoholic fatty liver disease (NAFLD) in adult and pediatric populations. Nutrition, physical activity, and behavioral modifications are critical components of the treatment regimen for all obese patients with NAFLD. Bariatric surgeries that affect or restrict the flow of food through the gastrointestinal tract may improve liver histology in morbidly obese patients with nonalcoholic steatohepatitis (NASH), although randomized clinical trials and quasi-randomized clinical studies are lacking. Early detection of NASH and hepatic fibrosis using noninvasive biochemical and imaging markers that may replace liver biopsy is the current challenge. © 2014 Elsevier Inc.

Current Opinion in HIV and AIDS | Year: 2015
Purpose of review Long-acting antiretroviral (ARV) agents are currently under development for the treatment of chronic HIV infection. This review focuses on data recently produced on injectable ARVs for patients living with HIV/AIDS and on the patients' perspectives on the use of these agents. Recent findings Crystalline nanoparticle formulations of the nonnucleoside reverse transcriptase inhibitor rilpivirine (TMC278) and of the HIV-1 integrase strand transfer inhibitor cabotegravir (GSK1265744) have progressed into phase II clinical trials as injectable maintenance therapy for patients living with HIV/AIDS with an undetectable viral load. Summary Phase II studies evaluating the coadministration of rilpivirine and cabotegravir intramuscularly to HIVinfected individuals with an undetectable viral load are currently underway. Rilpivirine and cabotegravir are characterized by different mechanisms of action against HIV and a favorable drug interaction profile, providing a rationale for coadministration. The high potency and low daily dosing requirements of oral cabotegravir and rilpivirine facilitate long-acting formulation development. Intramuscular dosing is preceded by an oral lead-in phase to assess safety and tolerability in individual participants. In addition to assessing the safety of injectable therapies in ongoing studies, it will be important to evaluate whether differences in drug adherence between injectable and oral therapies lead to different virologic outcomes, including rates of virologic failure and the emergence of resistance. Long-acting formulations may be associated with challenges, such as the management of adverse effects with persistent drug concentrations and the risk of virologic resistance, as drug concentrations decline following discontinuation. © 2015 Wolters Kluwer Health, Inc.

Over the past two decades, many more men are diagnosed with prostate cancer then die of the disease. This increase in diagnosis has led to aggressive treatment of indolent disease in many individuals and has been the impetus for finding a means of reducing the risk of prostate cancer. In the past decade, there have been eight large trials of prostate cancer risk reduction using dietary supplements, 5αÎ±-reductase inhibitors, or anti-estrogens. The only two trials which have demonstrated efficacy are those involving 5αÎ±-reductase inhibitors: the PCPT (finasteride) and REDUCE (dutasteride). This review examines prostate cancer risk reduction, with emphasis on conclusions that can be drawn from these two landmark studies. © 2011 Informa Healthcare.

This Small Business Innovation Research (SBIR) Phase I project is designed to provide a new probiotic product for public consumption that will address the rising US and global obesity issue and related concurrent increase in health problems such as diabetes and heart disease. According to the Centers for Disease and Prevention, 60-65% of the adult population in the US is overweight or obese. While implementation of lifestyle change (dietary modification and increased physical activity) improves this condition, relapse with additional weight gain is well documented. Current treatments are limited and include surgery and pharmacological agents with well documented health risks. This product is designed to work within the gastrointestinal tract, decreasing the amount of energy available to the host, and providing a means to the consumer to halt weight gain and decrease the risk of relapse, with possible positive modulation of underlying risk factors which contribute to declining health and contribute to increased health care costs.
The broader/commercial impacts of this research will be to reduce the high incidence of obesity. The rising cost of health care in the US has been well documented. Much of this cost is associated with increasing obesity, an underlying factor in the development of diseases such as diabetes and heart disease, commonly associated with an increase in abdominal circumference/inflammatory processes. According to the World Health Organization, three-fourths of the world population depends upon some form of non-pharmaceutical product for health care, providing a world-wide marketing opportunity for future commercialization.
