Low Aflatoxin Levels In Aspergillus Flavus-Resistant Maize Are Correlated With Increased Corn Earworm Damage And Enhanced Seed Fumonisin, Subbaiah Chalivendra, Fangneng Huang, Mark Busman, W. Paul Williams, Jong Hyun Ham

Faculty Publications

Preharvest mycotoxin contamination of field-grown crops is influenced not only by the host genotype, but also by inoculum load, insect pressure and their confounding interactions with seasonal weather. In two different field trials, we observed a preference in the natural infestation of corn earworm (CEW; Helicoverpa zea Boddie) to specific maize (Zea mays L.) genotypes and investigated this observation. The field trials involved four maize lines with contrasting levels of resistance to Aspergillus flavus. The resistant lines had 7 to 14-fold greater infested ears than the susceptible lines. Seed aflatoxin B1 (AF) levels, in mock- and A. flavus-inoculated ears were …

Targeted Engagement Of The Action Selection Network During Task-Oriented Arm Training After Stroke, Jill Campbell Stewart Pt,Phd, Kaci Handlery, Jessica F. Baird, Erika L. Blanck, Geetanjali Pathak, Stacy L. Fritz

Faculty Publications

Action selection (AS), or selection of an action from a set of alternatives, is an important movement preparation process that engages a frontal-parietal network. The addition of AS demands to arm training after stroke could be used to engage this motor planning process and the neural network that supports it. The purpose of this case series is to describe the feasibility and outcomes associated with task-oriented arm training aimed at engaging the AS behavioral process and the related neural network in three individuals with chronic stroke. Three participants with mild to moderate motor deficits completed 13 to 15 sessions of …

Demographic, Jurisdictional, And Spatial Effects On Social Distancing In The United States During The Covid-19 Pandemic, Rajesh P. Narayanan, James Nordlund, R. Kelley Pace, Dimuthu Ratnadiwakara

Faculty Publications

Social distancing, a non-pharmaceutical tactic aimed at reducing the spread of COVID-19, can arise because individuals voluntarily distance from others to avoid contracting the disease. Alternatively, it can arise because of jurisdictional restrictions imposed by local authorities. We run reduced form models of social distancing as a function of county-level exogenous demographic variables and jurisdictional fixed effects for 49 states to assess the relative contributions of demographic and jurisdictional effects in explaining social distancing behavior. To allow for possible spatial aspects of a contagious disease, we also model the spillovers associated with demographic variables in surrounding counties as well as …

Teachers completed a daily diary, documenting duration and frequency of product use. Following each product test, focus groups were conducted with teachers to assess facilitators …

Insomnia Is Associated With Frequency Of Suicidal Ideation Independent Of Depression: A Replication And Extension Of Findings From The National Health And Nutrition Examination Survey, Zach Simmons, Lance D. Erickson, Dawson Hedges, Daniel Kay

Faculty Publications

Objective: Insomnia is associated with suicidality, although the mechanisms of this association are unclear. This study sought to replicate previous findings showing that insomnia symptoms but not sleep duration are associated with frequency of suicidal ideation in adults. We further investigated whether depression or sleep duration moderates the association between insomnia symptoms and frequency of suicidal ideation.

Materials and Methods: We used the 2005–2006 cycle of the National Health and Nutrition Examination Survey to replicate previously reported findings from the 2007–2008 cycle. We used ordered logistic regression to determine whether insomnia symptoms were associated with frequency of suicidal ideation independently …

Faculty Publications

© 2020. Published by The Company of Biologists Ltd. Cellular polarization underlies many facets of cell behavior, including cell growth. The rod-shaped fission yeast Schizosaccharomyces pombe is a well-established, genetically tractable system for studying growth polarity regulation. S. pombe cells elongate at their two cell tips in a cell cycle-controlled manner, transitioning from monopolar to bipolar growth in interphase when new ends established by the most recent cell division begin to extend. We previously identified cytokinesis as a critical regulator of new end growth and demonstrated that Fic1, a cytokinetic factor, is required for normal polarized growth at new ends. …

Exploring Parents’ Ongoing Role In Romantic Development: Insights From Young Adults, Tyler B. Jamison, Hung Yuan Lo

Faculty Publications

Important decisions about romantic relationships are often made during adulthood, but the foundations for healthy relationships begin during childhood. Romantic development is related to experiences in the family of origin such as parenting, parents’ romantic history, and patterns of interaction within families. In order to better understand how this process unfolds into adulthood, we used relationship history interviews from 35 young adults (ages 24–40) to explore the mechanisms through which parents influence their children’s romantic development. We used Applied Thematic Analysis to guide our secondary analysis of relationship histories data. The findings suggest adult children internalize and apply the examples …

Zika Virus Infection Causes Widespread Damage To The Inner Ear, Kathleen T. Yee, Biswas Neupane, Fengwei Bai, Douglas E. Vetter

Faculty Publications

Zika virus (ZIKV) has been recently recognized as a causative agent of newborn microcephaly, as well as other neurological consequences. A less well recognized comorbidity of prenatal ZIKV infection is hearing loss, but cases of hearing impairment following adult ZIKV infection have also been recognized. Diminished hearing following prenatal ZIKV infection in a mouse model has been reported, but no cellular consequences were observed. We examined the effects of ZIKV infection on inner ear cellular integrity and expression levels of various proteins important for cochlear function in type I interferon receptor null (Ifnar1^−/−) mice following infection at …

Young Adults' Short-Term Trajectories Of Moderate Physical Activity: Relations With Self-Evaluation Processes, Alex .. Garn, Kelly L. Simonton

Faculty Publications

Young adults face numerous barriers that can undermine their engagement in healthy behaviors. For example, young adults on average experience disproportionally large declines in physical activity (PA) participation compared to other demographic groups. Self-evaluation processes may help explain these declines. This study investigated young adults' weekly trajectories of moderate physical activity, exploring self-evaluation processes, including self-efficacy and shame as time-varying covariates. A total of 71 young adults (Mage = 21.25,SD= 1.18; 55% male) reported moderate physical activity, exercise self-efficacy, and anticipated shame toward exercise once a week for 5 weeks. Latent growth curve models showed that a linear slope fit …

Music As A Management Tool In Elementary Physical Education: A Qualitative Investigation, David C. Barney, Keven A. Prusak

Classroom management is an important aspect for a K-12 teacher in any content area. The same applies in physical education (PE). In PE there are large spaces, students are moving, and in many cases, equipment (basketballs, rackets, hula hoops, etc.) is involved. Thus, making PE a unique challenge in regard to classroom management for PE teachers. One tool an elementary PE teacher can use for classroom management is music. For this study, one school administrator, 19 elementary-aged students and one PE teacher were interviewed to better understand their perspectives of music as a management tool in elementary PE. Findings indicate …

Redox-Sensitive Nanocomplex For Targeted Delivery Of Melittin, Bei Cheng, Peisheng Xu

Faculty Publications

Although peptide therapeutics have been explored for decades, the successful delivery of potent peptides in vitro and in vivo remains challenging due to the poor stability, low cell permeability, and off-target effects. We developed a redox sensitive polymer-based nanocomplex which can efficiently and stably deliver the peptide drug melittin for cancer therapy. The nanocomplex selectively targets cancer cells through lactobionic acid mediated endocytosis and releases melittin intracellularly upon the trigger of elevated redox potential. In vivo study proved that the targeted nanocomplex shows excellent potency in inhibiting tumor growth in a xenograft colon cancer mouse model. Thus, the polymer/melittin nanocomplexes …

Obesity Worsens Gulf War Illness Symptom Persistence Pathology By Linking Altered Gut Microbiome Species To Long-Term Gastrointestinal, Hepatic, And Neuronal Inflammation In A Mouse Model, Dipro Bose, Punnag Saha, Ayan Mondal, Brian Fanelli, Ratanesh K. Seth, Patricia Janulewicz, Kimberly Sullivan, Stephen Lasley, Ronnie Horner, Rita R. Colwell, Ashok K. Shetty, Nancy Klimas, Saurabh Chatterjee

Faculty Publications

Persistence of Gulf War illness (GWI) pathology among deployed veterans is a clinical challenge even after almost three decades. Recent studies show a higher prevalence of obesity and metabolic disturbances among Gulf War veterans primarily due to the existence of post-traumatic stress disorder (PTSD), chronic fatigue, sedentary lifestyle, and consumption of a high-carbohydrate/high-fat diet. We test the hypothesis that obesity from a Western-style diet alters host gut microbial species and worsens gastrointestinal and neuroinflammatory symptom persistence. We used a 5 month Western diet feeding in mice that received prior Gulf War (GW) chemical exposure to mimic the home phase obese …

Machine Intelligence For Nerve Conduit Design And Production, Caleb E. Stewart, Chin Fung Kelvin Kan, Brody R. Stewart, Henry W. Sanicola Iii, Jangwook P. Jung, Olawale A. R. Sulaiman, Dadong Wang

Faculty Publications

Nerve guidance conduits (NGCs) have emerged from recent advances within tissue engineering as a promising alternative to autografts for peripheral nerve repair. NGCs are tubular structures with engineered biomaterials, which guide axonal regeneration from the injured proximal nerve to the distal stump. NGC design can synergistically combine multiple properties to enhance proliferation of stem and neuronal cells, improve nerve migration, attenuate inflammation and reduce scar tissue formation. The aim of most laboratories fabricating NGCs is the development of an automated process that incorporates patient-specific features and complex tissue blueprints (e.g. neurovascular conduit) that serve as the basis for more complicated …

Intermittent Pneumatic Compression For Venous Thromboembolism Prevention: A Systematic Review On Factors Affecting Adherence, Richard Greenall, Rachel E. Davis

Statistical Analysis Of Safety Performance Of Displaced Left-Turn Intersections: Case Studies In San Marcos, Texas, Wenrui Qu, Qiao Sun, Qun Zhao, Tao Tao, Yi Qi

Faculty Publications

Displaced left-turn (DLT) intersections are designed to increase the mobility of vehicles by relocating the left-turn lane (lanes) to the far-left side of the road upstream of the main signalized intersection. Since DLT is a relatively new design and very limited crash data are available, previous studies have focused mainly on the analysis of its operational performance rather than its safety performance. To fill this gap, in this study, we investigated the safety performance of two DLT intersections located in San Marcos, Texas. Crash data from 2011 to April 2018 were extracted from the TxDOT Crash Record Information System (CRIS). …

A Glance Of P53 Functions In Brain Development, Neural Stem Cells, And Brain Cancer, Yuqing Xiong, Yun Zhang, Shunbin Xiong, Abie E. Williams-Villalobo

Faculty Publications

p53 is one of the most intensively studied tumor suppressors. It transcriptionally regulates a broad range of genes to modulate a series of cellular events, including DNA damage repair, cell cycle arrest, senescence, apoptosis, ferroptosis, autophagy, and metabolic remodeling, which are fundamental for both development and cancer. This review discusses the role of p53 in brain development, neural stem cell regulation and the mechanisms of inactivating p53 in gliomas. p53 null or p53 mutant mice show female biased exencephaly, potentially due to X chromosome inactivation failure and/or hormone-related gene expression. Oxidative cellular status, increased PI3K/Akt signaling, elevated ID1, and metabolism …

The watershed is drained by major streams and tributaries flowing in an easterly direction over Eocene-aged rocks and sediments of the Wilcox and Claiborne groups, and empty into the western arm of Caddo Lake. Since 1995, Caddo Lake and some of its tributaries have been included on the State of Texas Clean Water Act 303(d) list by the Texas Commission on Environmental Quality (TCEQ) for impairment due to mercury content in edible tissue, depressed dissolved oxygen, base metal concentrations, and low pH …

Equity 911: Framing Educational Equity As A National Emergency, Larissa Malone Phd

Faculty Publications

This paper considers equity as a crisis faced in classrooms across America. As such, an emergency framework is utilized to propose an approach that is apropos to the intense urgency a crisis requires. Using the Federal Emergency Management Agency’s National Planning Frameworks and their guiding principles, a survey of equity topics is discussed. In doing so, it is concluded that the level of inequity currently allowed in the field of education must be honestly assessed and a comprehensive plan that engages multiple stakeholders must be put in place for justice to be fully realized.

A Metacognitive Approach To Reconsidering Risk Perceptions And Uncertainty: Understand Information Seeking During Covid-19, Yan Huang, Chun Yang

Faculty Publications

The study examined the psychological drivers of information-seeking behaviors during the coronavirus disease 2019 (COVID-19) outbreak. Employing a two-wave (from April 16, 2020, to April 27, 2020) survey design (N= 381), the study confirmed that both risk perceptions and uncertainty were important antecedents to information seeking and that their effects were linked to emotional appraisals of the risk situation. Findings revealed nuanced relationships between these two constructs and emotional appraisals. Danger appraisal was positively associated with perceived susceptibility and susceptibility uncertainty but negatively related to severity uncertainty; hope appraisal depended on the interaction between uncertainty and risk perceptions. Implications of …

Racial Disparities In Air Pollution Burden And Covid-19 Deaths In Louisiana, Usa, In The Context Of Long-Term Changes In Fine Particulate Pollution, Kimberly A. Terrell, Wesley James

Faculty Publications

Black Americans in Louisiana are disproportionately dying from COVID-19, and environmental disparities may be contributing to this injustice. While Black communities in Louisiana's industrialized regions (e.g., Cancer Alley, Calcasieu Parish) have been overburdened with pollution for decades, this disparity has not been evaluated by using recent data. Here, we explore statewide relationships among air pollution burden, race, COVID-19 death rates, and other health/socioeconomic factors. Measures of pollution burden included satellite-derived particulate matter (PM2.5) concentrations and health risks from toxic air pollution (i.e., respiratory hazard [RH] and immunological hazard [IH], estimated by the Environmental Protection Agency). In addition, we evaluate changes …

Under Pressure: Time Management, Self-Leadership, And The Nurse Manager, Elizabeth Goldsby, Michael Goldsby, Christopher B. Neck, Christopher P. Neck

Faculty Publications

Decision making by nurses is complicated by the stress, chaos, and challenging demands of the work. One of the major stressors confronting nurses is perceived time pressure. Given the potential negative outcomes on nurses due to perceived time pressures, it seems logical that a nurse manager's ability to lead nurses in moderating this time pressure and in turn to make better decisions could enhance nurse well-being and performance. Paralleling research in the nursing literature suggests that, in order to improve patients' judgement of the care they received, nurse managers should embrace ways to lower nurses' perceived time pressure. In this …

Caitlin Hebert, Chin Chi Liu, Jacqueline M. Stephens, Leanne M. Redman, Nataki C. Douglas, Jennifer L. Sones

Faculty Publications

© 2020 by the authors. Licensee MDPI, Basel, Switzerland. Preeclampsia (PE) is a serious hypertensive disorder of pregnancy characterized by abnormal placental development with an unknown etiology. To better understand which women will develop PE, a number of maternal risk factors have been identified, including obesity. Visceral white adipose tissue (WAT) contains inflammatory mediators that may contribute to PE. To explore this, we utilized the blood pressure high (BPH)/5 mouse model of superimposed PE that spontaneously recapitulates the maternal PE syndrome. We hypothesized that BPH/5 visceralWAT adjacent to the female reproductive tract (reproductiveWAT) is a source of complement factors that …
