Background

Unpredictable childhood experiences are an understudied form of early-life adversity that impact neurodevelopment. The neurobiological processes by which exposure to early-life unpredictability impact development and vulnerability to psychopathology remain poorly understood. In the current study, we investigated the sex-specific consequences of early-life unpredictability on the limbic network, focusing on the hippocampus and the amygdala.

Methods

Participants included 150 youths (54% female). Early-life unpredictability was assessed using the Questionnaire of Unpredictability in Childhood (QUIC). Participants engaged in 1 or more task–functional magnetic resonance imaging scans between the ages of 8 and 17 (223 total observations) measuring blood oxygen level–dependent (BOLD) …

Positive And Negative Parity States Of 226-236th Isotopes, Ali A. Mezban, Falih H. Al-Khudair

Karbala International Journal of Modern Science

The level scheme of the ^226-236Th nuclei is analyzed using the Interacting Boson Model (IBM-1). The ground state band (g. s.-band), beta band (β-band), gamma band (γ-band) have been described in the sd model space. To calculate the negative parity energy levels, the model space is extended to sdf by adding the f-boson (L=3). A sequence of states in energy bands up to 3.5 MeV has been obtained. The decay of negative states below 1 MeV built on an octupole vibration modes is investigated. The transition probabilities in-band and inter-band are calculated using the wave function of the …

Structural Brain Correlates Of Childhood Inhibited Temperament: An Enigma-Anxiety Mega-Analysis, Janna Marie Bas-Hoogendam, Rachel Bernstein, Brenda E. Benson, Samuel E. C. Frank, Kristin A. Buss, Koraly Pérez-Edgar, Giovanni A. Salum, Andrea P. Jackowski, Rodrigo A. Bressan, Anderson M. Winkler

Human Genetics Publications

Objective

Childhood inhibited temperament (cIT) is associated with an increased risk for developing internalizing psychopathology. Neurobiological characteristics identified by structural magnetic resonance imaging (MRI) may elucidate the neural substrates for cIT, but studies are scarce and often focus on particular regions of interest. Moreover, current findings lack replication. This preregistered analysis from the ENIGMA-Anxiety Working Group examined structural brain characteristics associated with cIT using a comprehensive whole-brain approach.

Method

Temperament assessments (behavioral observations, parent/teacher reports or self-reports on cIT before age 13 years) and MRI data (age at scan, 6-25 years) from international research sites (Europe, North America, South America) …

Pan-Cancer Immune And Stromal Deconvolution Predicts Clinical Outcomes And Mutation Profiles, Bhavneet Bhinder, Verena Friedl, Sunantha Sethuraman, Davide Risso, Kami E Chiotti, Kyle P Ellrott, Christopher K Wong, Kofi Gyan, Aditya Deshpande, Marcin Imielinski, Rohan Bareja, Josh Stuart, Myron Peto, Katherine A Hoadley, Alexander J Lazar, Andrew D Cherniack, Jingchun Zhu, Shaolong Cao, Mark Rubin, Wenyi Wang, Oliver F Bathe, Nicolas Robine, Li Ding, Peter W Laird, Wanding Zhou, Hui Shen, Vésteinn Thorsson, Jen Jen Yeh, Matthew H Bailey, Daniel Cui Zhou, Xianlu L Peng, Mary Goldman, Yongsheng Li, Anil Korkut, Nidhi Sahni, D Neil Hayes, Michael K A Mensah, Ina Felau, Anab Kemal, Samantha Caesar-Johnson, John A Demchok, Liming Yang, Martin L Ferguson, Roy Tarnuzzer, Zhining Wang, Jean C Zenklusen, Paul Spellman, Olivier Elemento

Traditional gene expression deconvolution methods assess a limited number of cell types, therefore do not capture the full complexity of the tumor microenvironment (TME). Here, we integrate nine deconvolution tools to assess 79 TME cell types in 10,592 tumors across 33 different cancer types, creating the most comprehensive analysis of the TME. In total, we found 41 patterns of immune infiltration and stroma profiles, identifying heterogeneous yet unique TME portraits for each cancer and several new findings. Our findings indicate that leukocytes play a major role in distinguishing various tumor types, and that a shared immune-rich TME cluster predicts better …

Introduction: Patients with advanced cancer and their spousal caregivers who parent minor children report unmet parenting concerns and increased psychological distress. Seeking to address these important supportive care needs, this RCT examined the feasibility, acceptability, and initial evidence for the efficacy of a novel psychosocial intervention.

Patients and methods: Patients with a metastatic solid malignancy and their spouses completed self-reported validated assessments of psychological symptoms and cancer-related parenting outcomes and were then randomized to the parent support intervention or a usual care (UC) group. Both groups were reassessed 6 and 12 weeks later. Dyads randomized to the counselor-led intervention attended …

A Comparison Of Measured Versus Estimated Metabolic Equivalents (Mets) During The Farmer's Carry And Sled Push Exercises On A Commercially Available Step Mill, Colin Miller, Ethan Remotigue, Shane Hammer, J. Jay Dawes, Taylor K. Dinyer-Mcneely

Topics in Exercise Science and Kinesiology

Topics in Exercise Science and Kinesiology Volume 6: Issue 1, Article 8, 2025. The Stairmaster 10G ergometer allows users to perform non-traditional movements such as the sled push and farmer’s carry, which involve substantial upper and lower body contributions. Standard MET calculations for stair stepping do not account for this increase upper-body workload, so there is potential for error when aiming to determine exercise intensity based exclusively on estimated METs. The primary purpose of this study is to compare the metabolic and physiological effects of two training modes on the Stairmaster 10G ergometer, specifically evaluating the accuracy of MET values …

Robust Embeddings Of Genetics, Anatomy, And State Decoded From A Neuron’S Activity, Aidan Schneider

Arts & Sciences Graduate Student Theses and Dissertations

Neural spike trains are shaped by both extrinsic inputs and intrinsic structural constraints. While prior work has focused on how spike timing encodes externally driven variables, such as stimuli or behavior, this dissertation explores whether principles that organize neural activity in space and time—such as genetic cell type, anatomical location, and arousal state—are also embedded in the spiking output of individual neurons. I hypothesize that these organizing principles are not quenched as irrelevant variability, but rather multiplexed within the neural code itself. To test this, I attempt to decode these principles from the spike trains of neurons recorded in behaving …

ACTA2 pathogenic variants altering arginine 179 cause childhood-onset strokes due to moyamoya disease (MMD)-like occlusions of the distal internal carotid arteries, but the mechanisms of pathogenesis are unknown and no preventive treatments exist. Here we show that Acta2R179C/+ smooth muscle cells (SMCs) fail to fully differentiate and maintain stem cell-like features, including increased migration and glycolytic flux compared to wildtype (WT) SMCs. Increasing mitochondrial respiration with nicotinamide riboside (NR) drives differentiation and decreases migration of Acta2R179C/+ SMCs. Carotid artery injury of Acta2SMC-R179C/+ mice leads to premature death, intraluminal SMC accumulation leading to MMD-like occlusive lesions, neurologic symptoms, …

Structural And Functional Characterization Of Creb-Binding Protein (Crebbp) As A Histone Propionyltransferase, Guiling Cui, Marie Ley, Ariel E Mechaly, Linh-Chi Bui, Christina Michail, Julien Dairou, Guillaume Chevreux, Gautier Moroy, Michael R Green, Ahmed Haouz, Fernando Rodrigues Lima

Faculty, Staff and Student Publications

In addition to histone acetylation, histone lysine propionylation (such as the H3K18Pr mark) has recently attracted significant attention as a common and abundant modification linking the cellular metabolic state and gene expression. CREB-binding protein (CREBBP) and EP300 are key histone acetyltransferases that play a critical role in gene expression through their catalytic activity. Although CREBBP and EP300 are homologous enzymes with high structural similarities, they exhibit both redundant and specific functions. Dissecting the shared and divergent properties of CREBBP and EP300 is thus important to understand their roles. However, despite the importance of CREBBP, most mechanistic and structural studies have …

Differential Efficacy Of Bevacizumab And Erlotinib In Preclinical Models Of Renal Medullary Carcinoma And Fumarate Hydratase-Deficient Renal Cell Carcinoma, Niki M Zacharias, Manuel Ozambela, Menuka Karki, Rong He, Pankaj K Chauhan, Andres E Hernandez Gonzalez, Alberto Pieretti, Huiqin Chen, Carolyn De La Cerda, Zhiyuan Yu, Abha Grover, Samantha Hicks-Peña, Natalie W Fowlkes, Lei Wang, Tapati Maity, Priya Rao, Giannicola Genovese, Nizar M Tannir, Jose A Karam, Pavlos Msaouel

Renal medullary carcinoma (RMC) and fumarate hydratase (FH)-deficient renal cell carcinoma (RCC) are rare and highly aggressive cancers. Although the combination of vascular endothelial growth factor (VEGF) inhibition by bevacizumab and epidermal growth factor receptor (EGFR) inhibition by erlotinib is clinically used for both diseases, the differential effect of each component has not been investigated. Transcriptomic profiling revealed that RMC and FH-deficient tumor tissues demonstrate increased EGFR but not VEGF expression compared with adjacent normal kidney. Subsequent in vitro studies revealed that RMC and FH-deficient cell lines are sensitive to erlotinib treatment, whereas clear cell RCC cell lines are resistant. …

Cat: A Conditional Association Test For Microbiome Data Using A Permutation Approach, Yushu Shi, Liangliang Zhang, Kim-Anh Do, Robert R Jenq, Christine B Peterson

Faculty, Staff and Student Publications

In microbiome analysis, researchers often seek to identify taxonomic features associated with an outcome of interest. However, microbiome features are intercorrelated and linked by phylogenetic relationships, making it challenging to assess the association between an individual feature and an outcome. This paper proposes a novel conditional association test, CAT, that can account for other features and phylogenetic relatedness when testing the association between a feature and an outcome. CAT adopts a permutation approach, measuring the importance of a feature in predicting the outcome by permuting operational taxonomic unit/amplicon sequence variant counts belonging to that feature from the data and quantifying …

Pol Θ-Mediated End-Joining Uses Microhomologies Containing Mismatches, Yuzhen Li, Ngoc K Dang, Wei He, Mark Returan, Denisse Carvajal-Maldonado, Han Xu, Richard D Wood

Faculty, Staff and Student Publications

DNA polymerase theta (Pol θ) initiates repair of DNA double-strand breaks by pairing single strands at short "microhomologies". It is important to understand microhomology selection, as some cancer cells rely on Pol θ for survival. Here, we investigate end-joining by purified human Pol θ, employing DNA sequencing of products generated from oligonucleotide libraries having diverse 3' ends. Pol θ overwhelmingly selects short internal microhomologies found within 15 nucleotides of the terminus of single-stranded DNAs, restricting deletion size during end-joining. Significantly, we find that the selected microhomologies are usually interrupted by mismatches and that base pairing within 6 nucleotides of the …

A Hedgehog-Foxf Axis Coordinates Dental Follicle-Derived Alveolar Bone Formation, Chiaki Tsutsumi-Arai, Angel Ka Yan Chu, Seth N Nye, Yuntao Yang, Shion Orikasa, Akira Takahashi, Peter Carlsson, W Jim Zheng, Joshua D Welch, Noriaki Ono, Wanida Ono

Faculty, Staff and Student Publications

The alveolar bone is a specialized mineralized structure supporting the lifelong functionality of the tooth in mastication. The alveolar bone develops from the dental follicle (DF) during tooth root formation due to deliberate epithelial-mesenchymal interactions. However, how DF progenitor cell fates are regulated toward alveolar bone osteoblasts remains unknown. We find that Hedgehog signaling activities are transiently activated during the onset of tooth root formation and alveolar bone formation. Parathyroid hormone-related protein (PTHrP)-expressing DF cells are highly responsive to Hedgehog signaling, yet constitutive Hedgehog activation using Pthrp-creER and Ptch1-floxed alleles potently suppresses alveolar osteoblast and ligament differentiation of PTHrP+ DF …

Preferred Plants And Nectar Collecting Times For Honey Production, David Macfawn, Jennifer M.K. O'Keefe, Sophie Warny, Carol Wymer, June Rampy Ponder

Clemson Extension Publishing

This book addresses three important questions for South Carolina beekeepers – which plants are bees in South Carolina using for nectar forage, when bees collect nectar from those plants, and how can understanding nectar foraging habits inform beekeepers as they work to gather specific types of premium honey? In 2021, the South Carolina Beekeeper’s Association, led by David MacFawn, designed and implemented a statewide pollen study, the first in any state in over fifty years, to answer these questions. Informed by data gathered from 19 apiaries across the state, this book contains the results of that study, including large-scale melissopalynological …

Recent studies have highlighted the importance of mitochondria in NP cells and articular chondrocyte health. Since the understanding of mechanisms governing mitochondrial dynamics in these tissues is lacking, we investigated the role of OPA1, a mitochondrial fusion protein, in their homeostasis. OPA1 knockdown in NP cells altered mitochondrial size and cristae shape and increased the oxygen consumption rate. OPA1 governed the morphology of multiple organelles, including peroxisomes, early endosomes and cis-Golgi and loss resulted in the dysregulation of autophagy. Metabolic profiling and

Use Of High-Throughput Phenomics With And Without Fungicide As A Wheat Breeding Tool, Gerardo Ivan Rivera Collazo

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

Wheat (Triticum aestivum) is an important food staple for many countries around the world and current consumption and production data demonstrate a production deficit. Breeders are challenged to help close this gap in production by selecting better cultivars with improved yields. Several methods aim to accelerate the breeding process to reduce the time required for releasing an elite variety. One of the main breeding bottlenecks is the lack of fast and reliable phenotypic data acquisition that could dissect physiological and morphological plant data. High-throughput remote sensing could have the potential to reduce this bottleneck by streamlining data acquisition, …

Bioenergy Crop Production: Implications For Grassland Bird Communities In Southwestern Nebraska, Grace E. Schuster

School of Natural Resources: Dissertations, Theses, and Student Research

Biofuel and bioenergy systems are components of most climate stabilization pathways to reduce greenhouse gas emissions and limit global warming. Currently, corn (Zea mays) is the predominant feedstock used for bioenergy production in the United States. However, widespread production of this monoculture crop has resulted in many negative environmental impacts. The most notorious impact has been the loss of grassland habitat due to agriculture expansion which has had detrimental effects on wildlife that depend on grassland habitat. One such group, grassland birds, has faced steeper, more consistent, and more widespread declines than any other avian guild. Therefore, strategies …

Beneath The Crap: Assessing Melt Potential Through Debris Thickness And Sub-Debris Ice Temperature On The Ponkar Glacier, Nepal, Delaney Hartgen

Nepal: Geoscience in the Himalaya

Understanding melt potential beneath debris-covered glaciers is critical to predicting future glacial mass loss in the Himalayas. This study investigates the relationship between debris thickness and sub-debris ice temperature on the Ponkar Glacier, Nepal, through a combination of field measurements and remote sensing analysis. In-situ data collected along a 200-meter transect revealed that thicker debris layers consistently corresponded with colder sub-debris ice temperatures, supporting the hypothesis that debris acts as a thermal insulator. Surface ice temperatures remained near 0 °C regardless of debris thickness. Remote sensing products, including NDVI, albedo, and Landsat thermal data, provided additional spatial context, although a …

This study compared the effects of conventional tillage (CT), no-tillage (NT), and no-tillage with cover crops (CC) in selected soil physical and chemical properties (i.e., soil bulk density (D b), porosity (& fnof;t), field capacity (Theta FC), Permanent wilting point (Theta PWP), Plant available water …

To Pause With A Cliffhanger Or A Temporary Closure? The Differential Impact Of Serial Versus Episodic Narratives On Children's Physical Activity Behaviors, Amy Shirong Lu, Melanie C Green, Caio Victor Sousa, Jungyun Hwang, I-Min Lee, Debbe Thompson, Tom Baranowski

Children’s Nutrition Research Center Staff Publications

Research has supported the effectiveness of narratives for promoting health behavior, but different narrative presentation formats (serial vs. episodic) have seldom been compared. Suspense theories suggest that serial narratives, which do not provide a full resolution at the end of an episode, may create higher motivation for continued engagement with a story. Forty-four 8 to 12-year-old children were randomly assigned to watch an animation series designed for an existing active video game in which the plot was delivered either continuously across multiple episodes (serial) or in multiple yet relatively independent self-contained episodes (episodic). Controlling for social desirability, children who watched …
