Calorie restriction (CR) with adequate nutrient intake is a potential geroprotective intervention. To advance this concept in humans, we tested the hypothesis that moderate CR in healthy young-to-middle-aged individuals would reduce circulating biomarkers of cellular senescence, a fundamental mechanism of aging and aging-related conditions. Using plasma specimens from the Comprehensive Assessment of Long-term Effects of Reducing Intake of Energy (CALERIE™) phase 2 study, we found that CR significantly reduced the concentrations of several senescence biomarkers at 12 and 24 months compared to an ad libitum diet. Using machine learning, changes in biomarker concentrations emerged as important predictors of the change …

Irrigation Of Sand-Based Creeping Bentgrass Putting Greens With Nanobubble-Oxygenated Water, Eric J. Deboer, Michael D. Richardson, John H. Mccalla

Faculty Publications

Cultural and environmental factors can place creeping bentgrass (Agrostis stolonifera) under extreme stress during the summer months. This stress, coupled with the growth adaptation of creeping bentgrass, can result in shallow, poorly rooted stands of turf. To enhance root zone oxygen and rooting of creeping bentgrass, golf courses use methods such as core and solid-tine aerification, and sand topdressing. An additional method of delivering oxygen to the soil could be irrigation with nanobubble-oxygenated water. The properties of nanobubbles (NBs) allow for high gas dissolution rates in water. Irrigating with NB-oxygenated water sources may promote increased rooting of creeping bentgrass putting …

Serine Proteinase Inhibitors From Nicotiana Benthamiana, A Nonpreferred Host Plant, Inhibit The Growth Of Myzus Persicae (Green Peach Aphid), Honglin Feng, Georg Jander

Faculty Publications

BACKGROUND: The green peach aphid (Myzus persicae) is a severe agricultural crop pest that has developed resistance to most current control methods, requiring the urgent development of novel strategies. Plant proteinase inhibitors (PINs) are small proteins that protect plants against pathogens and/or herbivores, likely by preventing efficient protein digestion. RESULTS: We identified 67 protease genes in the transcriptomes of three M. persicae lineages (USDA-Red, G002 and G006). Comparison of gene expression levels in aphid guts and whole aphids showed that several proteases, including a highly expressed serine protease, are significantly overexpressed in the guts. Furthermore, we identified three genes encoding …

Understanding Inequality In U.S. Farm Subsidies Using Large-Scale Administrative Data, Jisang Yu, Sunghun Lim

Faculty Publications

Using a large-scale, individual-level administrative data set for 2008–2021, we document the inequality in farm program payments across all recipients in the U.S. By examining the relationship between within-county inequality and demographic characteristics of farmers in a county, we find that there is a positive association between the share of Black operators and within-county inequality. We also provide suggestive evidence that a substantial portion of racial and gender disparities in farm payments are associated with crop production characteristics. We then utilize name information in farm payment data to infer the race and gender of individual payees. The analysis using approximately …
