Tillering Of ‘Marandu’ Brachiaria Under Different Nitrogen Rates In The Brazilian Savannah, A. B. O. Assis, A. L. Bocchi, T. C. Pedrosa, A. O. Matos, A. P. B. Soares

IGC Proceedings (1977-2023)

The tiller is the basic unit of grass growth and tiller density determines the horizontal ground cover, leaves production and pastures perennially. The objective in this study was to quantify the number of aerial and basal tillers and basal:aerial tillers ratio in Urochloa brizantha cv. Marandu, established in Brazilian savannah, submitted to nitrogen doses (0, 50, 100 and 150 kg N/ha). The experiment was carried out in the Forage and Pasture Sector of Jataí Federal University (UFJ) and after soil correction and fertilization, plots were established with Marandu palisade grass in a randomized block design, with four replications and four …

The Influence Of High Density Grazing And Conventional, Rotational Grazing On Soil And Vegetation Parameters In The Semi-Arid And Mesic Grasslands Of South Africa, Jamie Paulse, C. Visser, P. J. Malan, G. N. Smit, F. H. De Witt

IGC Proceedings (1977-2023)

In South Africa, multi-camp rotational grazing using ‘conservative stocking rates’ have been the conventional approach to livestock grazing management systems. However, as of late, the high-desnity approach (used interchangeably – depending on the situation – with regenerative grazing, mob grazing, short duration, high pressure grazing, rapid rotation, time controlled, ultra-high density, holistic grazing and holistic resource management) has been adopted by numerous farmers. This approach is considered to be an adaptable one, incorporating the ‘herd effect’ concept, whereby large numbers of animals occupy an area for short periods of time, and allowed an extended rest period. It claims to improve …

Skin Conditions And Villainous Depictions In Anime Films: Exploring Unconscious Bias In Patient-Provider Interactions, Patricia Guzman

Research Symposium

Background: Film and artistic media have the ability to influence societal perception of dermatological conditions. Literature describes how both live-action and animated films tend to depict villainous characters with a disproportionately greater number of skin conditions, thus contributing to the stigma surrounding skin conditions and their association with moral deficiency. However, the majority of literature tends to examine films of cultural, historic, and aesthetic significance in Western canon. This study seeks to include perspectives from East Asian cinema by evaluating dermatological findings of heroes and villains in popular anime films and assessing whether an increased number of skin conditions …

Adipose Stem Cells As An Adjunct To Peripheral Nerve Surgery, Allison Podsednik Gardner, Raysa Cabrejo, Joseph Rosen

Research Symposium

Background: Currently, many different techniques exist for the surgical repair of peripheral nerves. The degree of injury dictates the repair and, depending on the defect or injury of the peripheral nerve, plastic surgeons can perform nerve repairs, grafts, and transfers. All the previously listed techniques are routinely performed in human patients, but a novel addition to these peripheral nerve surgeries involves concomitant fat grafting to the repair site at the time of surgery. Fat grafting provides adipose-derived stem cells (ADSCs) to the injury site. Though fat grafting is performed as an adjunct to some peripheral nerve surgeries, there is …

With the increase in screen time due to Covid-19 restrictions, digital media has become a valuable resource for remote learning, offering fun and educational interactions. However, the impact of incorporating educational technology or EdTech digital media applications into health education curricula on the performance of PK 4 students in understanding and adopting healthy living concepts remains understudied. By exploring the effectiveness of design elements and strategic approaches this research aims to evaluate newer technology-driven media in enhancing …

Choroid Plexus Morphology In Substance Abuse, Angelica Pham, Alan N. Francis

Research Symposium

Background: The choroid plexus (CP), a highly vascularized organ that lines the ventricles of the brain, serves several important functions that maintain homeostasis of the cerebrospinal fluid (CSF) surrounding the brain and protects the brain from harm by acting as part of the blood-cerebrospinal fluid barrier. Dysfunction in CP morphology and function has recently been associated with various conditions such as stroke, aging, neoplasms, hydrocephalus, Alzheimer’s disease, depression, and psychosis. This systematic review explores the morphological changes in the CP associated with substance abuse, which poses a significant problem worldwide.

Methods: A comprehensive literature search was performed to find …

Investigating The Behavioral Effects Of Microinjecting Hormones Into The Brain Of The Syrian Hamster (Mesocricetus Auratus), Fernando Dominguez, J. Chapa, A. Hinojosa, E. Alaniz, G. Padilla, Mario Gil

Research Symposium

Background: Hormones are important modulators of physiological functions, behaviors, emotions, and cognition; however, most neuroscientists focus on neurotransmitters and how these chemicals affect the brain and behavioral outcomes. Studies have shown that arginine-vasopressin (AVP), a hormone that is typically known for its regulation of kidney function, microinjected in the anterior hypothalamus (AHA) induces flank marking and aggressive behaviors in Syrian hamsters (Mesocricetus auratus). In the present study, we investigated the behavioral effects of two hormones, AVP and angiotensin, microinjected into the interfascicular nucleus (IF) and the bed nucleus stria terminalis (BNST), respectively, in the Syrian hamster.

Methods: Eleven hamsters (8 …

Cellular And Molecular Mechanisms Of Neurodegeneration In Early-Stage Diabetic Retinopathy, Andrew Callan, Sonal V. Jha, Laura Valdez, Andrew Tsin

Research Symposium

Background: Diabetic retinopathy (DR) remains the leading cause of blindness in working age Americans. There has yet to be any effective treatment to prevent the onset of the condition, only to treat late-stage disease. Research on early signs of disease have shown that changes in neural layers of the retina are the earliest signs of disease, preceding the vascular changes that currently define DR. This has sparked interest in the pathogenesis of the neurodegeneration involved in DR. This review explains the current understanding of the cellular and molecular mechanisms of neuronal degeneration in DR, as well as the potential pharmacological …

“Into The Sea Of Forgetfulness”: An Analysis Of Anna Komnene’S Alexiad In Relation To The First Crusade, Breya D. Scarlett

Swarthmore Undergraduate History Journal

Anna Komnene’s account of the First Crusade in her work The Alexiad provides invaluable insight into the Byzantine perspective of this pivotal event defining the 11th century. While shunned in a monastery, she wrote her celebrated work known as The Alexiad. Anna’s primary motivation for writing the biography stems from her desire to emphasize the accomplishments of her father, especially in regards to protecting the Byzantine Empire against invaders, both Latin and Turkish. For Anna, the crusade functions as a Western pretext for taking land away from the Byzantines. Comparing specific sieges in the First Crusade to their Latin …

“Now, What’S One Story I Wanted To Tell You?”: Oral History Exhibition Archives At The Chicago History Museum At The Turn Of The 21st Century, Arianne Nguyen

Swarthmore Undergraduate History Journal

Starting in the 1970s, American history museums have undergone a shift away from seeing themselves collections-focused historical societies acting as “temples to the past.” In the face of broader political challenges—civil rights, increasingly multicultural urban audiences, and the “culture wars” of the 1980s, public historians have sought to reclaim their institutions’ relevance by seeking to share their authority and mission with those “publics” they serve.

While secondary literature on public history has generally agreed that museums pulled off this shift—and museums themselves have touted successful exhibits and outreach—this essay uses a specific case study to complicate the narrative. The Chicago …

Defunding Cities: Reconsidering The Fiscal Sanctioning Measures Of State Punitive Preemption Statutes, Eliza Martin

University of Chicago Legal Forum

In an effort to deter and punish cities for passing ordinances that conflict with state priorities, states are utilizing a new form of legislative power: punitive preemption. It is generally considered a legitimate use of state power to utilize statutes to preempt local measures and ordinances deemed inconsistent with state policy. State legislatures, however, are attaching punitive mechanisms to preemption legislation that, in the event of local noncompliance, create criminal and civil liability for local officials, provide removal mechanisms for elected officials, and allow for the fiscal sanctioning of local governments.

This Comment considers whether local governments are legally protected …

Domestic Terror Across State Lines: A Failed Federal Framework, Sophia Houdaigui

University of Chicago Legal Forum

As white supremacist violence has substantially increased over the last two decades, calls to combat associated attacks have intensified. This Comment outlines the impact of the events of September 11, 2001 on domestic and international terrorism policy, contextualizing the subsequent invocation of international terrorism charges at significantly higher rates than those of domestic terrorism. It introduces the lack of a general criminal statute prohibiting acts of terrorism and discusses the issues associated with the varying definitions of domestic terrorism employed by the federal government.

Due to the lack of common terminology in referencing domestic terrorism, a number of white supremacists …

International Borders: Yours, Mine, And Ours, Beth Simmons

University of Chicago Legal Forum

International borders have become divisive issues in international and domestic politics. They have also become sites where the human rights of vulnerable persons have increasingly been documented as at risk. Policies of border hardening in the face of growing human mobility and other external threats—real and imagined—have made international borders focal sites of conflict at many levels. This Article argues that international law can reframe our understanding of bordering, leading to a more constructive approach to border management and greater respect for human rights. Borders are essentially institutions with the potential to settle coordination problems over territory. But of growing …

Characterization Of Variant Rnas Encapsidated During Bromovirus Infection By High-Throughput Sequencing, Sarah Dexheimer, Nipin Shrestha, Bandana Sharma Chapagain, Jozef J. Bujarski, Yanbin Yin

Food for Health: Publications

Previously, we described the RNA recombinants accumulating in tissues infected with the bromoviruses BMV (Brome mosaic virus) and CCMV (Cowpea chlorotic mottle virus). In this work, we characterize the recombinants encapsidated inside the purified virion particles of BMV and CCMV. By using a tool called the Viral Recombination Mapper (ViReMa) that detects recombination junctions, we analyzed a high number of high-throughput sequencing (HTS) short RNA sequence reads. Over 28% of BMV or CCMV RNA reads did not perfectly map to the viral genomes. ViReMa identified 1.40% and 1.83% of these unmapped reads as the RNA recombinants, respectively, in BMV and …

A New Perspective On Intervertebral Disc Calcification-From Bench To Bedside, Emanuel Novais, Rajkishen Narayanan, Jose Canseco, Koen Van De Wetering, Christopher Kepler, Alan Hilibrand, Alex Vaccaro, Makarand Risbud

Department of Orthopaedic Surgery Faculty Papers

Disc degeneration primarily contributes to chronic low back and neck pain. Consequently, there is an urgent need to understand the spectrum of disc degeneration phenotypes such as fibrosis, ectopic calcification, herniation, or mixed phenotypes. Amongst these phenotypes, disc calcification is the least studied. Ectopic calcification, by definition, is the pathological mineralization of soft tissues, widely studied in the context of conditions that afflict vasculature, skin, and cartilage. Clinically, disc calcification is associated with poor surgical outcomes and back pain refractory to conservative treatment. It is frequently seen as a consequence of disc aging and progressive degeneration but exhibits unique molecular …

Tony Catros, Oral History Interview, 2024, Matt Jones

Tony Catros, nicknamed "Cassius" by his fraternity brothers, served as an active member of the fraternity from 1963 until 1967. Catros relates his grandparents' immigration to the United States and his graduation from Redford Union High School before applying at EMU on a whim with friend Gary Griswold. Catros describes the differences between the Arms and other fraternities, his employment with Ypsilanti State Hospital while an Arm, and the importance of winning the All-Sports Trophy. He describes the reputation of Arm of Honor prior to his membership, and the initiation period that was part of all pledges' lives. He describes …

Interplay Between Acetylation And Ubiquitination Of Imitation Switch Chromatin Remodeler Isw1 Confers Multidrug Resistance In Cryptococcus Neoformans, Yang Meng, Yue Ni, Zhuoran Li, Tianhang Jiang, Tianshu Sun, Yanjian Li, Xindi Gao, Hailong Li, Chenhao Suo, Chao Li, Sheng Yang, Tian Lan, Guojian Liao, Tongbao Liu, Ping Wang, Chen Ding

School of Medicine Faculty Publications

Cryptococcus neoformans poses a threat to human health, but anticryptococcal therapy is hampered by the emergence of drug resistance, whose underlying mechanisms remain poorly understood. Herein, we discovered that Isw1, an imitation switch chromatin remodeling ATPase, functions as a master modulator of genes responsible for in vivo and in vitro multidrug resistance in C. neoformans. Cells with the disrupted ISW1 gene exhibited profound resistance to multiple antifungal drugs. Mass spectrometry analysis revealed that Isw1 is both acetylated and ubiquitinated, suggesting that an interplay between these two modification events exists to govern Isw1 function. Mutagenesis studies of acetylation and ubiquitination sites …

Synthesis And Characterization Of Cellulose Microfibril-Reinforced Polyvinyl Alcohol Biodegradable Composites, Fatemeh Mahdiyeh-Boroujeni, Gabriella Fioravanti, Ronald Kander

School of Design and Engineering Papers

The pursuit of an environmentally sustainable manufacturing process requires the substitution of less damaging and recyclable solutions for harmful reagents. This study aims to assess the effectiveness of using cellulose microfibrils synthesized via different hydrolysis reactions as reinforcing agents in polyvinyl alcohol (PVA) at varying concentrations. The investigation explores the morphology, thermal properties, and chemical behavior of the cellulose particles. The cellulose microfibrils (CMFs) produced using citric acid exhibited the highest yield and aspect ratio. Notably, particles from organic acids demonstrated greater thermal stability, with oxalic acid-derived particles displaying the maximum thermal degradation temperature. Subsequently, cast films of PVA reinforced …

Periodontitis And Alzheimer’S Disease: Is There A Connection?, William Lundergan, Kavitha Parthasarathy, Navid Knight

Pacific Faculty Work

The oral health/systemic health connection has been an area of research interest that increased dramatically during the 1990s. Periodontal disease has been associated with a number of systemic conditions, including cardiovascular disease, diabetes, pre-term low-birth-weight infants, respiratory conditions, rheumatoid arthritis, cancer, and Alzheimer’s disease. Inflammation is the obvious link that connects periodontal disease with these conditions, but is this association casual or causal? We will address the biologic plausibility, evidence from human studies, evidence from animal studies, and therapeutic interventions as we review the current understanding of the link between periodontitis and Alzheimer’s disease.

Microglia-Derived Exosomes Modulate Myelin Regeneration Via Mir-615-5p/Myrf Axis, Xiao-Yu Ji, Yu-Xin Guo, Li-Bin Wang, Wen-Cheng Wu, Jia-Qi Wang, Jin He, Rui Gao, Javad Rasouli, Meng-Yuan Gao, Zhen-Hai Wang, Dan Xiao, Wei-Feng Zhang, Bogoljub Ciric, Yuan Zhang, Xing Li

Department of Neurology Faculty Papers

Demyelination and failure of remyelination in the central nervous system (CNS) characterize a number of neurological disorders. Spontaneous remyelination in demyelinating diseases is limited, as oligodendrocyte precursor cells (OPCs), which are often present in demyelinated lesions in abundance, mostly fail to differentiate into oligodendrocytes, the myelinating cells in the CNS. In addition to OPCs, the lesions are assembled numbers of activated resident microglia/infiltrated macrophages; however, the mechanisms and potential role of interactions between the microglia/macrophages and OPCs are poorly understood. Here, we generated a transcriptional profile of exosomes from activated microglia, and found that miR-615-5p was elevated. miR-615-5p bound to …

Willingness-To-Pay For Rationed Goods: Bobcat Harvest Permits In Indiana, Nicholas A. Lancaster, Carson Reeling, John G. Lee, Richard T. Melstrom, Joe N. Caudell, Geriann Albers

Department of Agricultural Economics Faculty Publications

We use contingent valuation to estimate hunter and trapper willingness to pay (WTP) for a hypothetical bobcat harvest permit being considered in Indiana. Harvest permits would be rationed, with limits on aggregate and individual harvests. A model of permit demand shows that WTP may be subject to “congestion effects” which attenuate welfare gains from relaxing harvest limits. Intuitively, relaxing limits may directly change an individual’s expected harvest and, hence, WTP. Participation may subsequently change, with congestion offsetting welfare increases. These effects may lead to apparent scope insensitivity that may be endemic in the context of rationed goods.

Incubating Education: The Lived Experiences Of Louisiana Elementary And Middle School Teachers When Piloting A 4-H Stem School Enrichment Curriculum, Crystal Rose Ahrens

LSU Doctoral Dissertations

This study addressed a deficiency in the agricultural literacy of the U.S. population by focusing on the challenges that core subject teachers face when integrating agriculture into their curriculum. Using a phenomenological research approach, this investigation explored the lived experiences of Louisiana teachers who piloted a 4-H STEM curriculum, focusing on the growth in agricultural literacy of the teachers while instructing third and eighth-grade students on the agricultural-based and STEM-focused topic of embryology. Employing a transcendental phenomenological approach, I acknowledged my biases through reflexivity and adhered to ethical considerations, including informed consent and confidentiality. Key findings emerged through four themes …

Death, Dreaming, And Diaspora: Achieving Orientation Through Afro-Spirituality, Liz Johnston, Jaime Elizabeth Johnston

LSU Doctoral Dissertations

Enslavement, colonization, and the systems that uphold racial injustice were and still are a series of new, unfathomable, and challenging experiences that prompt individuals within the diaspora to seek orientation. How does a human cope with centuries of attempts at the systematic destruction of their humanity, culture, and identity? How can they reclaim that identity, especially when so much of it seems lost? I address these questions by utilizing texts from the expansive body of work regarding ethnographic-historical-religious studies on Afro-spiritual practices to better analyze instances in literature in the ongoing practice of diasporic orientation. In this project, I argue …
