Genomics Of Secondarily Temperate Adaptation In The Only Non-Antarctic Icefish, Angel G. Rivera-Colón, Niraj Rayamajhi, Bushra Fazal Minhas, Giovanni Madrigal, Kevin T. Bilyk, Veronica Yoon, Mathias Hüne, Susan Gregory, C. H.Christina Cheng, Julian M. Catchen

Department of Biology Faculty Scholarship and Creative Works

White-blooded Antarctic icefishes, a family within the adaptive radiation of Antarctic notothenioid fishes, are an example of extreme biological specialization to both the chronic cold of the Southern Ocean and life without hemoglobin. As a result, icefishes display derived physiology that limits them to the cold and highly oxygenated Antarctic waters. Against these constraints, remarkably one species, the pike icefish Champsocephalus esox, successfully colonized temperate South American waters. To study the genetic mechanisms underlying secondarily temperate adaptation in icefishes, we generated chromosome-level genome assemblies of both C. esox and its Antarctic sister species, Champsocephalus gunnari. The C. esox genome is …

Cafuncapa: A Knowledgebase For Systematic Functional Annotations Of Apa Events In Human Cancers, Kexin Huang, Sijia Wu, Xiaotong Yang, Tiangang Wang, Xi Liu, Xiaobo Zhou, Liyu Huang

Faculty, Staff and Student Publications

Alternative polyadenylation (APA) is a widespread posttranscriptional regulation process. APA generates diverse mRNA isoforms with different 3' UTR lengths, affecting mRNA expression, miRNA binding regulation and alternative splicing events. Previous studies have demonstrated the important roles of APA in tumorigenesis and cancer progression through diverse aspects. Thus, a comprehensive functional landscape of diverse APA events would aid in a better understanding of the underlying mechanisms related to APA in human cancers. Here, we built CAFuncAPA (https://relab.xidian.edu.cn/CAFuncAPA/) to systematically annotate the functions of 15478 APA events in human pan-cancers. Specifically, we first identified APA events associated with cancer survival and tumor …

Automated Ct Pancreas Segmentation For Acute Pancreatitis Patients By Combining A Novel Object Detection Approach And U-Net, Yang Deng, Lan Lan, Lei You, Kai Chen, Li Peng, Weiling Zhao, Bin Song, Yi Wang, Zhiwei Ji, Xiaobo Zhou

Faculty, Staff and Student Publications

Acute pancreatitis is an inflammatory disorder of the pancreas. Medical imaging, such as computed tomography (CT), has been widely used to detect volume changes in the pancreas for acute pancreatitis diagnosis. Many pancreas segmentation methods have been proposed but no methods for pancreas segmentation from acute pancreatitis patients. The segmentation of an inflamed pancreas is more challenging than the normal pancreas due to the following two reasons. 1) The inflamed pancreas invades surrounding organs and causes blurry boundaries. 2) The inflamed pancreas has higher shape, size, and location variability than the normal pancreas. To overcome these challenges, we propose an …

Editorial: Structure And Function Of Chloroplasts, Volume Iii, Hongbo Gao, Alistair J. Mccormick, Rebecca Roston, Yan Lu

Department of Biochemistry: Faculty Publications

Chloroplasts are endosymbiotic organelles derived from cyanobacteria. They have a double envelope membrane, including the outer envelope and the inner envelope. A complex membrane system, thylakoids, exists inside the chloroplast. It is the site of the light-dependent reactions of photosynthesis. The stroma is the main site of the carbon fixation reactions. Although photosynthesis is a very complicated process with many proteins involved, there are many other important processes that occur in chloroplasts, including the regulation of photosynthesis, the biogenesis and maintenance of the structures, carbohydrate, lipid, tetrapyrrole, amino acid, and isoprenoid metabolism, production of some phytohormones, production of specialized metabolites, …

Why Some People Are Hesitant To Receive Covid-19 Boosters: A Systematic Review, Yam B. Limbu, Bruce A. Huhmann

Department of Marketing Faculty Scholarship and Creative Works

As the COVID-19 pandemic continues and transitions to an endemic stage, booster vaccines will play an important role in personal and public health. However, convincing people to take boosters continues to be a key obstacle. This study systematically analyzed research that examined the predictors of COVID-19 booster vaccine hesitancy. A search of PubMed, Medline, CINAHL, Web of Science, and Scopus uncovered 42 eligible studies. Globally, the average COVID-19 booster vaccination hesitancy rate was 30.72%. Thirteen key factors influencing booster hesitancy emerged from the literature: demographics (gender, age, education, income, occupation, employment status, ethnicity, and marital status), geographical influences (country, region, …

The Effect Of Relative Humidity On Eddy Covariance Latent Heat Flux Measurements And Its Implication For Partitioning Into Transpiration And Evaporation, Weijie Zhang, Martin Jung, Mirco Migliavacca, Rafael Poyatos, Diego G.

Nelson

Department of Agricultural and Biological Systems Engineering: Faculty Publications

While the eddy covariance (EC) technique is a well-established method for measuring water fluxes (i.e., evaporation or 'evapotranspiration’, ET), the measurement is susceptible to many uncertainties. One such issue is the potential underestimation of ET when relative humidity (RH) is high (>70%), due to low-pass filtering with some EC systems. Yet, this underestimation for different types of EC systems (e.g. open-path or closed-path sensors) has not been characterized for synthesis datasets such as the widely used FLUXNET2015 dataset. Here, we assess the RH-associated underestimation of latent heat fluxes (LE, or ET) from different EC systems for 163 sites in …

Impact Of The Dimethyl Sulfoxide Reductase Superfamily On The Evolution Of Biogeochemical Cycles, Michael Wells, Minjae Kim, Denise M. Akob, Partha Basu, John F. Stolz

UK CARES Faculty Publications

The dimethyl sulfoxide reductase (or MopB) family is a diverse assemblage of enzymes found throughout Bacteria and Archaea. Many of these enzymes are believed to have been present in the last universal common ancestor (LUCA) of all cellular lineages. However, gaps in knowledge remain about how MopB enzymes evolved and how this diversification of functions impacted global biogeochemical cycles through geologic time. In this study, we perform maximum likelihood phylogenetic analyses on manually curated comparative genomic and metagenomic data sets containing over 47,000 distinct MopB homologs. We demonstrate that these enzymes constitute a catalytically and mechanistically diverse superfamily defined not …

Magnetic Nanocomposites For The Remote Activation Of Sulfate Radicals For The Removal Of Rhodamine B, Pranto Paul, Marissa Nicholson, J. Zach Hilt

UK CARES Faculty Publications

The widespread presence of numerous organic contaminants in water poses a threat to the ecological environment and human health. Magnetic nanocomposites exposed to an alternating magnetic field (AMF) have a unique ability for magnetically mediated energy delivery (MagMED) resulting from the embedded magnetic nanoparticles; this localized energy delivery and associated chemical and thermal effects are a potential method for removing contaminants from water. This work developed a novel magnetic nanocomposite—a polyacrylamide-based hydrogel loaded with iron oxide nanoparticles. For this magnetic nanocomposite, persulfate activation and the contamination removal in water were investigated. Magnetic nanocomposites were exposed to AMF with a model …

High Sucrose Consumption Decouples Intrinsic And Synaptic Excitability Of Agrp Neurons Without Altering Body Weight., Austin C Korgan, Klausen Oliveira-Abreu, Wei Wei, Sophie L A Martin, Zoey J D Bridges, José Henrique Leal-Cardoso, Catherine Kaczorowski, Kristen M S O'Connell

Faculty Research 2023

BACKGROUND/OBJECTIVE: As the obesity epidemic continues, the understanding of macronutrient influence on central nervous system function is critical for understanding diet-induced obesity and potential therapeutics, particularly in light of the increased sugar content in processed foods. Previous research showed mixed effects of sucrose feeding on body weight gain but has yet to reveal insight into the impact of sucrose on hypothalamic functioning. Here, we explore the impact of liquid sucrose feeding for 12 weeks on body weight, body composition, caloric intake, and hypothalamic AgRP neuronal function and synaptic plasticity.

METHODS: Patch-clamp electrophysiology of hypothalamic AgRP neurons, metabolic phenotyping and food …

Genetic Mapping Of Microbial And Host Traits Reveals Production Of Immunomodulatory Lipids By Akkermansia Muciniphila In The Murine Gut., Qijun Zhang, Vanessa Linke, Katherine A Overmyer, Lindsay L Traeger, Kazuyuki Kasahara, Ian J Miller, Daniel E Manson, Thomas J Polaske, Robert L Kerby, Julia H Kemis, Edna A Trujillo, Thiru R Reddy, Jason D Russell, Kathryn L Schueler, Donald S Stapleton, Mary E Rabaglia, Marcus Seldin, Daniel M Gatti, Gregory R Keele, Duy T Pham, Joseph P Gerdt, Eugenio I Vivas, Aldons J Lusis, Mark P Keller, Gary Churchill, Helen E Blackwell, Karl W Broman, Alan D Attie, Joshua J Coon, Federico E Rey

Faculty Research 2023

The molecular bases of how host genetic variation impacts the gut microbiome remain largely unknown. Here we used a genetically diverse mouse population and applied systems genetics strategies to identify interactions between host and microbe phenotypes including microbial functions, using faecal metagenomics, small intestinal transcripts and caecal lipids that influence microbe-host dynamics. Quantitative trait locus (QTL) mapping identified murine genomic regions associated with variations in bacterial taxa; bacterial functions including motility, sporulation and lipopolysaccharide production and levels of bacterial- and host-derived lipids. We found overlapping QTL for the abundance of Akkermansia muciniphila and caecal levels of ornithine lipids. Follow-up in …

Significance Of Secondary Fe-Oxide And Fe-Sulfide Minerals In Upper Peak Ring Suevite From The Chicxulub Impact Structure, Christina M. Verhagen, Ji In Jung, Sonia M. Tikoo, Axel Wittmann, David A. Kring, Stefanie Brachfeld, Laying Wu, Dale H. Burns, Sean P.S. Gulick

Department of Earth and Environmental Studies Faculty Scholarship and Creative Works

The suevite (polymict melt rock-bearing breccia) composing the upper peak ring of the Chicxulub impact crater is extremely heterogeneous, containing a combination of relict clasts and secondary minerals. Using scanning electron microscopy coupled with energy-dispersive X-ray spectroscopy (SEM/EDS) and electron probe microanalysis (EPMA), we investigated the nature and occurrence of primary and secondary Fe-oxide and Fe-sulfide minerals to better understand hydrothermal trends such as mineral precipitation and dissolution, and to document the remobilization of Fe and associated siderophile elements within suevites. Large primary Fe-oxides (~20–100 µm) reveal decomposition and dissolution patterns, forming sub-micrometer to micrometer Fe-oxide phases. Secondary sub-micrometer Fe-oxide …

Sampled! Revisiting Fair Use And De Minimus Copying In Music Sampling, Connie Davis Nichols

The Business, Entrepreneurship & Tax Law Review

Could your favorite mash-up be an infringement under Copyright law? At one time, sound recordings featured a simplified copyright infringement analysis under the 2005 Bridgeport Music decision, which held that the Copyright Act provided copyright holders an exclusive right to sample their own work and any other sampling constituted infringement, unless it was a fair use. This decision remained intact until the VMG decision in 2016, which renewed the availability of the de minimis infringement defense in music sampling cases and held that sampling without a license did not constitute infringement so long as the sample was not recognizable by …

Buried Hope: Assessing The Future Of Carbon Sequestration In The U.S. Under The Updated 45q Tax Credit, Alden Smith

The Business, Entrepreneurship & Tax Law Review

The urgent need to combat climate change has prompted governments world-wide to explore innovative policy measures to reduce greenhouse gas emissions. One such measure is the process of carbon capture and sequestration in which carbon dioxide is captured either directly from the atmosphere or prior to its release. This article will analyze updates to the 45Q tax credit passed in the Inflation Reduction Act of 2022, in which Congress increased tax incentives for industries that use carbon capture technology. This analysis will explain carbon capture technology, survey use of the technology, and discuss the viability of the latest updates to …

Grass Trait–Abundance Relationships And The Role Of The Functional Composition Of The Neighboring Community, Robert J. Griffin-Nolan, Brody Sandel

Biology

Questions

Plant traits can predict a species‘ relative abundance and its influence on ecosystem processes. However, trait expression and the relative abundance of a species are also influenced by its abiotic and biotic environment. Here, we ask whether the relationship between plant traits and relative abundance is modified by abiotic (e.g., climate and topography) and biotic factors (e.g., community taxonomic and functional diversity) across Californian grasslands.

Location

San Francisco Bay Area.

Methods

We measured specific leaf area (SLA; leaf area/dry mass) and plant height of 19 grass species (family: Poaceae) across 117 plots. We also quantified the relative abundance of …

2022-2023 Christmas Bird Counts, Don Paseka

Nebraska Bird Review

Sixteen counts were run in the 2022-2023 CBC season. Because of weather and rescheduling issues, the Crawford, Harrison, and Harlan County counts were cancelled. Eight of the counts were completed during the first week of the count period and the other eight were scattered throughout the remainder of the count period. An early December cold snap seemed to drive many of the birds south, but the weather on actual count days was fairly benign: mostly dry with an average high of 34˚F and an average low of 19˚F and with three circles reporting light snow. The total number of species …

Valproic Acid Affects Neuronal Specification And Differentiation During Early Optic Tectum Development Of Zebrafish, Sierra C. Dixon, Bailey J. Calder, Shane M. Lilya, Brandon M. Davies, Annalie Martin, Maggie Peterson, Jason M. Hansen, Arminda Suli

Library/Life Sciences Undergraduate Poster Competition 2023

The mammalian superior colliculus and its non-mammalian homolog, the optic tectum (OT), are midbrain structures that integrate multimodal sensory inputs and guide non-voluntary movements in response to prevalent stimuli. Recent studies have implicated this structure as a possible site affected in Autism Spectrum Disorder (ASD). Interestingly, fetal exposure to valproic acid (VPA) has also been associated with an increased risk of ASD in humans and animal models. Therefore, we took the approach of determining the effects of VPA treatment on zebrafish OT development as a first step in identifying the mechanisms that allow its formation. We describe the normal OT …

Making Morbidity Multiple: History, Legacies, And Possibilities For Global Health, Justin Dixon, Emily Mendenhall, Edna Bosire, Felix Limbani, Rashida A. Ferrand, Clare I R. Chandler

Brain and Mind Institute

Multimorbidity has been framed as a pressing global health challenge that exposes the limits of systems organised around single diseases. This article seeks to expand and strengthen current thinking around multimorbidity by analysing its construction within the field of global health. We suggest that the significance of multimorbidity lies not only in challenging divisions between disease categories but also in what it reveals about the culture and history of transnational biomedicine. Drawing on social research from sub-Saharan Africa to ground our arguments, we begin by describing the historical processes through which morbidity was made divisible in biomedicine and how the …

Understanding The Factors Affecting The Quantity And Composition Of Street Litter: Implication For Management Practices, Alessandra Rossi, Meiyin Wu, Bernabas T. Wolde, Kevin W. Zerbe, Tsung Ta David Hsu, Ariane Giudicelli, Rosana Da Silva

Department of Biology Faculty Scholarship and Creative Works

Some urban areas have more litter than others. Understanding the reason for this is important not only for dealing with urban littering but also for marine water quality because approximately 80% of the world's marine litter originates on land. This study aimed to better understand the quality and quantity of litter on sidewalks along with the sampling site's socio-economic attributes to better discern why some areas have more/different litter than others and what, if any, are the implications for a more tailored waste management strategy. We surveyed twice each of the 35 sites we selected from the Lower Passaic River …

Dredged Sediments Contain Potentially Beneficial Microorganisms For Agriculture And Little Harmful Cyanobacteria, Megan A. Rúa, Ashley N. Julian, Louise Stevenson

Biological Sciences Faculty Publications

Abstract Introduction Soils worldwide are degrading, raising concerns about our ability to feed the growing global population. Soil amendments that can alleviate degradation are gaining attention. The application of sediments dredged from waterways to agricultural fields has increasing promise as a means for improving degraded soils. However, herbaceous plant species may have difficulty establishing on dredged material because of low nutrient availability, inhibitory levels of toxins, unsuitable moisture conditions and lack of microorganisms capable of ameliorating these characteristics. To counteract these issues, we sought to understand if the use of a cover crop would increase the abundance, diversity and function …

Associations Between Preweaning Calf Feeding Behaviors With Age At First Calving And Lactational Performance Using An Automatic Calf Feeder, Turner H. Swartz, Christina Petersson-Wolfe

Dairy Science and Food Science Faculty Publications: 2022 to Present

The objective of this retrospective observational study was to determine whether preweaning calf behaviors and milk replacer (MR) intake from an automatic calf feeder were associated with age at first calving and first-lactation performance. Calves were housed in groups with access to an automatic calf feeder for 7 wk with a maximum milk allowance of 1,800 g/d of MR (12 L/d). Outcomes of interest included age at first calving (n = 137), first-lactation mature-equivalent 305-d (ME305) milk yield (n = 132), and first-lactation ME305 energy-corrected milk (ECM) yield (n = 132). Linear models included the fixed effects of the daily …

Mediators And Islamophobia: A Qualitative Case Study Of Cacrep Counseling Students' Perceptions Of Cultural Competency With Future Muslim Clients, Regina Mustafa

Education Doctorate Dissertations

Research suggests that having mental health needs and identifying as Muslim act as double stressors since some Muslims mistrust mental health providers out of fear of discrimination. Since its inception in 1981, the Council for the Accreditation of Counseling and Related Educational Programs (CACREP) has strived to ensure higher education institutions prepare future professional counselors with the awareness, knowledge, and skills to meet the needs of an increasingly diverse clientele. In addition, CACREP’s adoption of the Multicultural and Social Justice Counseling Competencies (MSJCCs) indicates an educational commitment to addressing the oppression and inequities prevalent in counseling practice. In the United …

Encoding Permanent Records Of Transcription In The Genome, Francesco Ettore Emiliani

Dartmouth College Ph.D Dissertations

Current approaches to study cellular transcriptional states offer only a single frame in the life of a cell, often in a destructive fashion. This means that our state snapshot neither has the context of the past, nor the ability to be traced into the future. To overcome this, we present a technology that can permanently encode gene expression for later recovery. Our technology uses transcriptional responses to guide CRISPR/AsCas12a to ‘write’ information into the cell’s own genome, creating a permanent and heritable record of this response. By placing a set of AsCas12a guides under the control of a Wnt-responsive TCF/LEF …

(Wp 2023-01) Objectivity In Economics And The Problem Of The Individual, John B. Davis

Economics Working Papers

This paper addresses objectivity in economics. It criticizes a closed science, ‘view from nowhere’ conception of economics and defends an open science, ‘view from somewhere’ conception of objective science. It ascribes the first conception to mainstream economics, associates it with its principle practices – reductionist modeling, formalization, limited interdisciplinarity, and value neutrality – and argues their foundation is the Homo economicus individual conception. Two problematic consequences of adopting this stance are: (i) value blindness regarding the range and complexity of human values; (ii) fatalism regarding human behavior associated with employing a tenseless representation of time. The paper contrasts the principle …
