Perivascular Macrophages In The Neonatal Macaque Brain Undergo Massive Necroptosis After Simian Immunodeficiency Virus Infection, Diana G. Bohannon, Yueying Wang, Colin H. Reinhart, Julian B. Hattler, Jiangtao Luo, Hamid R. Okhravi, Jianshui Zhang, Qingsheng Li, Marcelo J. Kuroda, Woong-Ki Kim

Nebraska Center for Virology: Faculty Publications

We previously showed that rhesus macaques neonatally infected with simian immunodeficiency virus (SIV) do not develop SIV encephalitis (SIVE) and maintain low brain viral loads despite having similar plasma viral loads compared to SIV-infected adults. We hypothesize that differences in myeloid cell populations that are the known target of SIV and HIV in the brain contribute to the lack of neonatal susceptibility to lentivirus-induced encephalitis. Using immunohistochemistry and immunofluorescence microscopy, we examined the frontal cortices from uninfected and SIV-infected infant and adult macaques (n = 8/ea) as well as adults with SIVE (n = 4) to determine differences in myeloid …

One Hand Washes The Other: Designing Mutually Beneficial Honors Contracts, Antonina Bambina

National Collegiate Honors Council Monographs: Chapters

At their best, honors contracts can be creative, challenging, exceptional learning opportunities for students and faculty. At their worst, they promote busywork that fails to deliver enhanced educational experiences. While I am proud of the many contracts that allowed honors students at my former institution, the University of Southern Indiana, to collaborate on customized learning and deeper relationships with course material and faculty, I also found myself on occasion having to apologize to students or faculty for the stunted, lackluster projects that one party or the other proposed. These conflicting sentiments illustrate why Richard Badenhausen urges the honors community to …

Attributions Of Blame In A Hypothetical Child Sexual Abuse Case: Roles Of Behavior Problems And Frequency Of Abuse, Kate Theimer, David J. Hansen

Department of Psychology: Faculty Publications

Youth who are blamed for their sexual abuse may experience increased negative outcomes, such as amplified self-blame. Similarly, blaming nonoffending parents can impede their ability to support their child following disclosure. Understanding the factors that influence how people perceive victim, caregiver, and perpetrator responsibility is imperative for the protection and treatment of families who have experienced sexual abuse. Little research has explored victim and abuse characteristics that influence the perception of sexual abuse. As such, the purpose of this study was to examine the roles of behavior problems and frequency of abuse in the attribution of blame in a hypothetical …

Contextualizing The Covid-19 Era In Puerto Rico: Compounding Disasters And Parallel Pandemics, Catherine Garcia, Fernando I. Rivera, Marc A. Garcia, Giovani Burgos, María P. Aranda

Department of Sociology: Faculty Publications

Objectives: The COVID-19 outbreak has worsened the ongoing economic crisis in Puerto Rico by creating "parallel pandemics" that exacerbate socioeconomic and health inequalities experienced by its most vulnerable residents. Unfortunately, conditions on the island have been largely overlooked by national media outlets and the mainland U.S. population. Thus, this research report aims to draw attention to the disparate burden multiple and compounding disasters have on older island-dwelling Puerto Rican adults’ health and well-being.

Methods: We characterize the lived experiences of the older population in Puerto Rico by incorporating data from numerous sources and contextualizing the effects of compounding disasters, the …

Are Biological Consequences Of Childhood Exposures Detectable In Telomere Length Decades Later?, Blakelee R. Kemp, Kenneth F. Ferraro

Department of Sociology: Faculty Publications

Negative early-life exposures have been linked to a host of poor adult health outcomes, but are such early exposures associated with cellular senescence decades later? This study uses data from the Health and Retirement Study to examine the association between six childhood exposure domains (e.g., socioeconomic disadvantage, risky parental behavior) and a biomarker of aging, telomere length, among 4,935 respondents. Telomere length is obtained from DNA of cells found in saliva and is measured as the telomere repeat copy number to single gene copy number ratio (T/S). Men who as children were exposed to risky parental …

Ipsilateral And Contralateral Torque Responses To Bilateral And Unilateral Maximal, Fatiguing, Isokinetic Leg Extensions, Tyler J. Neltner, John Paul V. Anders, Joshua L. Keller, Robert W. Smith, Terry J. Housh, Richard J. Schmidt, Glen O. Johnson

Department of Nutrition and Health Sciences: Faculty Publications

Background: Few studies have compared performance fatigability (PF) for bilateral versus unilateral isokinetic tasks. Objectives: The purpose of this study was to examine: Mode- specific testing responses to isokinetic fatigue, differences in PF between bilateral and unilateral leg extensions, and the effects of fatiguing, unilateral, dynamic leg extensions on contralateral isokinetic peak torque (PT) and maximal voluntary isometric contraction (MVIC). Methods: Eight men (mean ± SD: age= 22.5 ± 2.5 yr.) completed pre- and post-testing for PT and MVIC following 50 bilateral, unilateral right or left leg maximal, isokinetic leg extensions at 180°·s-1, on three separate days. Fatigue-induced decreases in …

Nativity And Country Of Origin Variations In Life Expectancy With Functional Limitations Among Older Hispanics In The United States, Marc A. Garcia, Adriana M. Reyes, Catherine García, Chi-Tsun Chiu, Grecia Macias

Department of Sociology: Faculty Publications

This study examined racial/ethnic, nativity, and country of origin differences in life expectancy with and without functional limitations among older adults in the United States. We used data from the National Health Interview Survey (1999–2015) to estimate Sullivan-based life tables of life expectancies with functional limitations and without functional limitations by sex for U.S.-born Mexicans, foreign-born Mexicans, U.S.-born Puerto Ricans, island-born Puerto Ricans, foreign-born Cubans, and U.S.-born Whites. We find that Latinos exhibit heterogeneous life expectancies with functional limitations. Among females, U.S.-born Mexicans, foreign-born Mexicans, and foreign-born Cubans spend significantly fewer years without functional limitations, whereas island-born Puerto Ricans spend …

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Background: Centenarian studies are important sources for understanding of factors that contribute to longevity and healthy aging. Clinico-neuropathological finding is a key in identifying pathology and factors contributing to age-related cognitive decline and dementia in the oldest old.

Objective: To characterize the cross-sectional relationship between neuropathologies and measures of premortem cognitive performance in centenarians.

Methods: Data were acquired from 49 centenarians (≥98 years) from the Georgia Centenarian Study. Cognitive assessment from the time point closest to mortality was used (<1 year for all subjects) and scores for cognitive domains were established. Neuropathologies [cerebral atrophy, ventricular dilation, atherosclerosis, cerebral amyloid angiopathy (CAA), Lewy bodies, hippocampal sclerosis (HS), hippocampal TDP-43 proteinopathy, neuritic plaque (NP) and neurofibrillary tangle (NFT) counts, Braak staging, and National Institute on Aging-Reagan Institute (NIARI) criteria for the neuropathological diagnosis of Alzheimer’s disease (AD)] were compared among subjects with different ratings of dementia. Linear regression was applied to evaluate the association between cognitive domain scores and neuropathologies.

Results: Wide ranges of AD-type neuropathological changes were observed in both non-demented and demented subjects. Neocortical NFT and Braak staging …

Escaping Death: Naloxone's Chemical Nature And Potential To Combat The Opioid Epidemic, Abigale Miller

Honors Program: Senior Projects (Public)

Naloxone is a life-saving drug with the ability to reverse an opioid overdose. As the opioid epidemic’s death toll rises, we can turn to Naloxone as a tool to combat the crisis. The epidemic, born of corruption, has a wide reach among the people of the United States, with especially firm grasps on middle-aged people, sufferers of chronic pain, white Americans and those living in the eastern portion of the country. Naloxone’s elegant design saves lives by effectively competing for a position on an opioid biding receptor in the brain to almost instantly end an overdose and restore normal breathing. …

Brief Report: Sexual Wellbeing In Heterosexual, Mostly Heterosexual, And Bisexually Attracted Men And Women, Tierney K. Lorenz

Department of Psychology: Faculty Publications

Objective: To assess differences in sexual wellbeing among men and women with exclusively heterosexual, mostly heterosexual, and bisexual attractions. Method: An anonymous online survey in a convenience sample of 597 young adults (394 women, 203 men; average age = 20.04) assessed patterns of sexual attraction, desire, sexual functioning, and sexual satisfaction using validated questionnaires. Results: Individuals with mostly heterosexual attractions reported significantly higher solitary sexual desire than exclusively heterosexual individuals (women: d = 0.64; men: d = 0.68). Partnered sexual desire did not differ between groups. Women with exclusively heterosexual attractions reported significantly higher sexual functioning and …

Biological Risk Profiles Among Latino Subgroups In The Health And Retirement Study, Catherine García, Jennifer A. Ailshire

Department of Sociology: Faculty Publications

Background and Objectives: Latinos residing in the United States exhibit an increased risk for cardiovascular and meta- bolic diseases compared to non-Latino whites. This elevated risk contributes to a significantly higher prevalence of diabetes and hypertension among Latino adults. Examining biological risk profiles of older Latinos as a “pan-ethnic group” and by Latino subpopulations may help to explain the increased burden of disease in later life among this population. The objec- tive of this study is to document biological risk profiles among a nationally representative sample of older U.S. Latinos by nativity and country of origin.

Culture And The Development Of Traditional Medicine In Africa, Rowland Edet, Oyedolapo Isaac Bello, Julianah Babajide

Department of Sociology: Faculty Publications

Traditional medicine has been the dominant healthcare system in Africa before westernization, civilization and colonialism. For people living in the rural areas, traditional medicine is easily available, accessible and affordable. The purpose of this paper is to examine how the cultural way of the life of Africans has contributed to the emergence and development of traditional therapeutic systems in the continent. By explaining the way Africans perceive illness and disease, this paper argues that various forms of healing were predicated on the sociocultural environment of the people. The paper therefore opts for concerted efforts in the development of traditional medicine …

Disability And The Immigrant Health Paradox: Gender And Timing Of Migration, Marc A. Garcia, Adriana M. Reyes, Sunshine Rote

Department of Sociology: Faculty Publications

Although research has documented better health and longer life expectancy among the foreign-born relative to their U.S.-born counterparts, the U.S. Mexican-origin immigrant population is diverse and the healthy immigrant effect likely varies by key structural and demographic factors such as gender, migration history, and duration in the United States. Using a life course framework, we use data from the Hispanic Established Populations for the Epidemiologic Study of the Elderly (H-EPESE 1993–2013) which includes Mexican-American individuals aged 65 and older to assess the heterogeneity in the immigrant health advantage by age of migration and gender. We find that age of migration …

Racial/Ethnic And Nativity Differences In Cognitive Life Expectancies Among Older Adults In The United States, Marc A. Garcia, Brian Downer, Chi-Tsun Chiu, Joseph L. Saenz, Sunshine Rote, Rebeca Wong

Department of Sociology: Faculty Publications

Background and Objectives: To document racial/ethnic and nativity differences by gender in cognitive life expectancies among older adults in the United States.

Research Design and Methods: Sullivan-based life tables were used to estimate cognitively normal, cognitively impaired/ no dementia (CIND), and dementia life expectancies by gender for White, Black, U.S.-born Hispanic, and foreign-born Hispanic adults 50 years and older in the Health and Retirement Study.

Results: Among women, the number of years spent living with dementia for Whites, Blacks, U.S.-born Hispanics, and foreign-born Hispanics was 1.6, 3.9, 4.7, and 6.0 years, respectively. For men, Whites lived 1.1 years with dementia …

Late Life Depressive Symptoms And Cognitive Function Among Older Mexican Adults: The Past And The Present, Joseph L. Saenz, Marc A. Garcia, Brian Downer

Department of Sociology: Faculty Publications

Objective: To evaluate associations between depression and individual cognitive domains and how changes in depressive symptoms relate to cognition three years later in the context of Mexico, a developing country experiencing rapid aging.

Method: Data comes from waves 3 (2012) and 4 (2015) of the Mexican Health and Aging Study (n=12,898, age 50+). Depression is ascertained using a modified Center for Epidemiologic Studies – Depression Scale. Cognition is assessed using verbal learning, verbal memory, visual scanning, verbal fluency, visuospatial ability, visual memory, and orientation tasks. Depressive symptoms and cognitive functioning were both measured in 2012 and 2015. Scores across cognitive …

Embodied Transitions In Michel De Montaigne, Nora Martin Peterson, Peter Martin

Department of Modern Languages and Literatures: Faculty Publications

Sixteenth-century French philosopher Michel de Montaigne was one of the first writers to reflect on embodiment. “I am myself the matter of my book,” he proclaims in the introduction to his Essays. Montaigne writes about various moments of embodied transitions: a near-death experience, reflections on aging and cognitive decline, and a lengthy discussion of how to cope in the face of devastating loss. Taking an interdisciplinary perspective by analyzing the relationship between embodiment, health representations, and geropsychological themes, this chapter analyzes Montaigne’s in-between moments, arguing that Montaigne’s essays—innovative in their own time—remain important in discussing embodied transitions today.

Differential Relationship Between Physical Activity And Intake Of Added Sugar And Nutrient-Dense Foods: A Cross-Sectional Analysis, Karsten Koehler, Julie B. Boron, Teresa M. Garvin, Matthew R. Bice, Jeffrey R. Stevens

Jeffrey Stevens Publications

A curvilinear relationship exists between physical activity (PA) and dietary energy intake (EI), which is reduced in moderately active when compared to inactive and highly active individuals, but the impact of PA on eating patterns remains poorly understood. Our goal was to establish the relationship between PA and intake of foods with varying energy and nutrient density. Data from the 2009–2010 United States National Health and Nutrition Examination Survey were used to include a Dietary Screener Questionnaire for estimated intakes of added sugar, fruits and vegetables, whole grains, fiber, and dairy. Participants (n = 4766; 49.7% women) were divided into …

Arsenite Exposure Suppresses Adipogenesis, Mitochondrial Biogenesis And Thermogenesis Via Autophagy Inhibition In Brown Adipose Tissue, Jiyoung Bae, Yura Jang, Heejeong Kim, Kalika Mahato, Cameron Schaecher, Issac M. Kim, Eunju Kim, Seung-Hyun Ro

Department of Biochemistry: Faculty Publications

Arsenite, a trivalent form of arsenic, is an element that occurs naturally in the environment. Humans are exposed to high dose of arsenite through consuming arsenite-contaminated drinking water and food, and the arsenite can accumulate in the human tissues. Arsenite induces oxidative stress, which is linked to metabolic disorders such as obesity and diabetes. Brown adipocytes dissipating energy as heat have emerging roles for obesity treatment and prevention. therefore, understanding the pathophysiological role of brown adipocytes can provide effective strategies delineating the link between arsenite exposure and metabolic disorders. Our study revealed that arsenite significantly reduced differentiation of murine brown …

Physical Performance Trajectories And Mortality Among Older Mexican Americans, Miriam Mutambudzi, Nai-Wei Chen, Bret Howrey, Marc A. Garcia, Kyriakos S. Markides

Department of Sociology: Faculty Publications

Background: We sought to identify distinct trajectory classes of physical performance in Mexican Americans aged 75 years and older and to examine whether these trajectories predict mortality.

Methods: We used four waves of Hispanic Established Populations for Epidemiologic Studies of the Elderly (H-EPESE) data for adults 75 years and older from 2004–2005 to 2013. Latent growth curve analysis was used to identify distinct trajectory classes. Multinomial logistic regression analysis was used to examine the association between baseline characteristics and the newly constructed trajectories. Cox proportional hazards regression models examined the hazard of mortality as a function of Short Physical Performance …

Gender And Age Of Migration Differences In Mortality Among Older Mexican Americans, Adriana M. Reyes, Marc A. Garcia

Department of Sociology: Faculty Publications

Objectives: Using a gendered life course perspective, we examine whether the relationship between age of migration and mortality is moderated by gender among a cohort of older Mexican-Americans.

Methods: Data from the Hispanic Established Populations for the Epidemiological Study of the Elderly and recently matched mortality data are used to estimate Cox proportional hazard models.

Results: Our findings indicate the relationship between age of migration and mortality is moderated by gender suggesting a more nuanced perspective of the immigrant mortality paradox. Among men, midlife migrants exhibit an 18 percent lower risk of mortality compared to their U.S.-born …

Effects Of Stem And Response Order On Response Patterns In Satisfaction Ratings, Jolene D. Smyth, Glenn D. Israel, Milton G. Newberry Iii, Richard G. Hull

Department of Sociology: Faculty Publications

Considerable research has examined the effect of response option order in ordinal bipolar questions such as satisfaction questions. However, no research we know of has examined the effect of the order of presentation of concepts in the question stem or whether stem order moderates response option order. In this article, we experimentally test the main and interaction effects of both stem and response option order for items in self-administered surveys on response distributions and answer changes in eight satisfied/dissatisfied questions. We find consistent evidence that response option order impacts answers. We also find that the order of “satisfied” or “dissatisfied” …

Childhood Misfortune And Handgrip Strength Among Black, White, And Hispanic Americans, Natalie R. Smith, Kenneth F. Ferraro, Blakelee R. Kemp, Patricia M. Morton, Sarah A. Mustillo, Jacqueline L. Angel

Department of Sociology: Faculty Publications

Objective: Although early-life insults may affect health, few studies use objective physical measures of adult health. This study investigated whether experiencing misfortune during childhood is associated with handgrip strength (HGS) in later life.

Method: Data on childhood misfortune and adult characteristics from the Health and Retirement Study were used to predict baseline and longitudinal change in HGS among White, Black, and Hispanic American men and women.

Results: Regression analyses revealed that multiple indicators of childhood misfortune were related to HGS at baseline, but the relationships were distinct for men and women. Over the study, having one childhood impairment predicted steeper …

Avoiding The Major Causes Of Death: Does Childhood Misfortune Reduce The Likelihood Of Being Disease Free In Later Life?, Monica M. Williams, Blakelee R. Kemp, Kenneth F. Ferraro, Sarah A. Mustillo

Department of Sociology: Faculty Publications

Objectives: Although previous research reveals the detrimental effects of early misfortune on the development of chronic diseases in later life, few studies have investigated its effects on remaining disease free. This study draws on cumulative inequality theory to investigate whether experiencing childhood misfortune reduces the likelihood of remaining disease free over time.

Method: This study utilizes five waves of data from the Health and Retirement Study to test whether five domains of childhood misfortune predict being disease free at baseline (2004) and developing disease over time (2004–2012).

Results: Respondents reporting risky parental behaviors during childhood were less likely to be …
