Characterizing Human Gut Bacterial Tir Domains In Vitro, In Gnotobiotic Mice And Malnourished Children, James Stephen Weagley

Arts & Sciences Graduate Student Theses and Dissertations

Worldwide, malnutrition (undernutrition) is the leading cause of death in children under 5. Studies of healthy members of birth cohorts from low- and middle-income countries have identified a program of gut microbial community development that is disrupted in children with severe acute malnutrition (SAM) and moderate acute malnutrition (MAM). This perturbed gut microbiome development has been linked to the pathogenesis of malnutrition. Repair of this gut microbial dysbiosis in children with MAM with microbiota-directed complementary foods (MDCFs) designed to increase the fitness and expressed beneficial functions of underrepresented bacterial community members restores healthy growth, including improvements in mediators of metabolic …

Becoming With Pigs, Plants, And People: Examining The Formation Of Human-Animal Mutualisms In Neolithic Northeastern China, Ximena Lemoine

Arts & Sciences Graduate Student Theses and Dissertations

More than 10,000 years ago humans in multiple parts of Eurasia began to form increasingly more entangled and mutually dependent relationships with non-human animals. In some cases, the elaboration of these relationships would result in evolutionary change, resulting in biologically distinct or domesticated populations. The last several decades of research show that this process is ongoing and polymorphous, emerging out of sustained human-animal interactions that develop along historically contingent trajectories shaped by particular biological, environmental, and cultural contexts. Thus, understanding domestication as an evolutionary process necessitates investigation into species- and context-specific developmental trajectories of human-animal interaction. The pig (Sus scrofa) …

Rspo2 And Rankl Signal Through Lgr4 To Regulate Osteoclastic Premetastatic Niche Formation And Bone Metastasis, Zhiying Yue, Xin Niu, Zengjin Yuan, Qin Qin, Wenhao Jiang, Liang He, Jingduo Gao, Yi Ding, Yanxi Liu, Ziwei Xu, Zhenxi Li, Zhengfeng Yang, Rong Li, Xiwen Xue, Yankun Gao, Fei Yue, Xiang H-F Zhang, Guohong Hu, Yi Wang, Yi Li, Geng Chen, Stefan Siwko, Alison Gartland, Ning Wang, Jianru Xiao, Mingyao Liu, Jian Luo

Therapeutics targeting osteoclasts are commonly used treatments for bone metastasis; however, whether and how osteoclasts regulate premetastatic niche and bone tropism are largely unknown. In this study, we report that osteoclast precursors (OPs) can function as a premetastatic niche component that facilitates breast cancer (BCa) bone metastasis at early stages. At the molecular level, unbiased GPCR ligand/agonist screening in BCa cells suggested that R-spondin 2 (RSPO2) and RANKL, through interaction with their receptor LGR4, promoted osteoclastic premetastatic niche formation and enhanced BCa bone metastasis. This was achieved by RSPO2/RANKL-LGR4 signal modulating the WNT inhibitor DKK1 through Gαq and β-catenin signaling. …

IGC Proceedings (1977-2023)

Oat, triticale, wheat and barley are small grain cereals used as forage in many temperate Mexican regions. The objective was to determine crude protein and van Soest fiber contents of these forages cut at 80, 96, 108, 121, 138 and 153 days after seeding. Cultivars used were: Chihuahua (OC) for oat; Arne (TA), Bicentenario (TB) and Siglo XXI (TS) for triticale; Saturno (WS) for wheat; and San Marcos (BSM) for barley. Experiment was under greenhouse conditions from November 2015 to May 2016. Crude protein (CP), neutral (NDF) and acid (ADF) detergents fibers were determined on the forage harvested at each …

Collection Priorities Of Pasture Genetic Resources In The Paniceae Native To South Africa, F. L. Müller, M. Trytsman, E. L. Masemola, M. I. Kgonothi, N. R. Mkhize, T. J. Tjelele

IGC Proceedings (1977-2023)

There is an urgent need for the prioritization and ex situ conservation of pasture grass species. Many pasture grasses are still in the process of domestication and grasslands in the tropical, subtropical, semi-arid and arid regions of the world are therefore a major source of genetic material for future forage improvement. Within South Africa, it was found that the Paniceae contains several species with high pasture value and that many populations of these species are found in water-limited environments. Therefore, it was proposed that a strategy be developed for the South African National Forage Genebank to prioritize efforts to collect …

Changes In Defoliation Patterns Of Plant Functional Groups Under Variable Herbage Allowance In Campos Grasslands, N. Caram, F. Casalás, Pablo Soca, M. Wallau, M. Cadenazzi, P. Boggiano

IGC Proceedings (1977-2023)

Several studies have evaluated separately forage production, botanical composition, leaf traits and animal performance. However, few of them have focused on defoliation patterns at the level of functional groups (FGs) under different and variable herbage allowance (HA), especially in natural, diverse grasslands. The objective was to evaluate the relationship between HA and leaf traits on defoliation patterns of mature beef cows in the autumn, winter and spring. We evaluated the grazing probability (GP), intensity of defoliation (ID), and leaf traits on 14 species that represent more than 80% of total dry matter of the pasture. The experiment at which we …

Synthesis And Biosynthesis Of 3-Hydroxy-Β-Lactam Antibiotics, Wei Wei

Arts & Sciences Graduate Student Theses and Dissertations

Novel treatments for tuberculosis (TB) are urgently needed to conquer this global health crisis. Unlike canonical β-lactam antibiotics that target transpeptidases by hydrolyzing the lactam ring, tabtoxinine-β-lactam (TβL) functions as a potent glutamine synthetase (GS) inhibitor by forming a transition state mimic. TβL has the potential to be used as an anti-TB agent by targeting the nitrogen metabolic pathway of pathogenic mycobacteria. This work reported an innovative, convergent, and flexible cross-metathesis method to obtain the fully protected TβL scaffold. The trans-olefin intermediate provides possibilities for synthesizing various derivatives through alkene functionalization reactions. We also developed and optimized a solid phase …

SDSU Beef Day 2022 Summary Publication

Study Description:

Six herds of yearling steers (n=127) will graze native summer pastures from May to August at the Cottonwood Field Station near Philip, South Dakota. Six pastures are divided into two groups: a continuous grazing (CG) treatment with a low, moderate, and high stocking density and a virtually fenced rotational (VFR) grazing system with the same stocking densities. VenceTM virtual fence collars were placed on all animals within the study and collected GPS data at 5-minute intervals. The CG collars are not actively managed. The VFR system is actively managed through the collars and rotated based on the amount …

Ultrafast High-Energy Micro-Supercapacitors Based On Open-Shell Polymer-Graphene Composites, Lulu Yao, Naresh Eedugurala, Paramasivam Mahalingavelar, Daniel J. Adams, Kaiping Wang, Kevin S. Mayer, Jason D. Azoulay, Tse Nga Ng

Faculty Publications

Micro-supercapacitors are poised to serve as on-chip power sources for electronics. However, the challenge to simultaneously increase their power, energy, and lifetime demands new material combinations beyond current carbon-based systems. Here, we demonstrate that electro-deposition of an open-shell conjugated polymer with reduced graphene oxide achieves electrodes with capacitance up to 186 mF cm⁻² (372 F cm⁻³). The extended delocalization within the open-shell polymer stabilizes redox states and facilitates a 3 V wide potential window, while the hierarchical electrode structure promotes ultrafast kinetics. The micro-supercapacitor shows a high power density of 227 mW cm⁻² with an energy …

Post-Hpv-Vaccination Mast Cell Activation Syndrome: Possible Vaccine-Triggered Escalation Of Undiagnosed Pre-Existing Mast Cell Disease?, Lawrence B Afrin, Tania T Dempsey, Leonard B Weinstock

Open Access Publications

For nearly a decade, case reports and series have emerged regarding dysautonomias-particularly postural orthostatic tachycardia syndrome (POTS)-presenting soon after vaccination against human papilloma virus (HPV). We too have observed a number of such cases (all following vaccination with the Gardasil product), and have found several to have detectable mast cell activation syndrome (MCAS) as well as histories suggesting that MCAS was likely present long before vaccination. We detail 11 such cases here, posing a hypothesis that HPV vaccination (at least with the Gardasil product) may have triggered or exacerbated MCAS in teenagers previously not recognized to have it. Only recently …

Muskrat Textualism, Matthew L.M. Fletcher

Northwestern University Law Review

The Supreme Court decision McGirt v. Oklahoma, confirming the boundaries of the Creek Reservation in Oklahoma, was a truly rare case in which the Court turned back arguments by federal and state governments in favor of American Indian and tribal interests. For more than a century, Oklahomans had assumed that the reservation had been terminated and acted accordingly. But only Congress can terminate an Indian reservation, and it simply had never done so in the case of the Creek Reservation. Both the majority and dissenting opinions attempted to claim the mantle of textualism, but their respective analyses led to …

Can Livestock Alone Be The Main Source Of Income From Rangelands In Poor Countries?, Hossein Arzani, Mohammad Jafari, H. Moradii

IGC Proceedings (1977-2023)

In many countries due to the high population of land holders, there is insufficient range area for each land holder to cover all life expenses. In such places, the income of only livestock in rangelands is not enough to cover living expenses of landholders. The ideas in this paper suggest that researchers should create and explore economic models that incorporate the multiple use concept in rangelands and show how multiple uses are compatible with livestock grazing and to sustain the livelihood of rangeland families.

Assessment Of Climate Events In Changma Season (Korean Monsoon) For Production Trend Of Sorghum-Sudangrass Hybrid (Sorghum Bicolor L.) In The Central Inland Regions Of Korea Using Time Series Analysis, M. Kim, J. Y. Kim, M. H. Jo, K. Sung, H. Jo

IGC Proceedings (1977-2023)

This study aimed to assess the impact of climate events in the Changma (Korean Monsoon) season on the production trend of sorghum-sudangrass hybrid (SSH) in central inland regions using time series analysis. The dataset in Suwon from 1988–2013 (n = 388) was generated by merging SSH data and climate data. The accumulated temperature (SHAT, ℃), rainfall amount (SHRA, mm) and sunshine duration (SHSD, hr) from seeding to harvesting were used to assess their impact on the trend of dry matter yield (DMY, kg/ha) for SSH. Furthermore, heavy rainfall (HRF) and typhoons (TPH) were considered as climate events. As a result, …

Assessment Of Causality Between Climate Variables And Production For Whole Crop Maize Using Structural Equation Modeling, M. Kim, J. Y. Kim, M. H. Jo, H. Jo, K. Sung

A Robust Technique For Optimal Fitting Of Roll-Over Shapes Of Human Locomotor Systems, Ganesh M. Bapat, Sara A. Myers

Journal Articles

The roll-over shape (ROS) effectively characterizes the lower limb's ability to roll forward during the single-limb support phase of human walking. ROS is modelled as an optimally fitted circular arc to the center of pressure (CoP) data transformed in the shank/leg-based local coordinate system. The commonly used method for optimal fitting of ROS is complex to implement and eliminates inherent individual variability in the ROS parameters during walking. We propose and validate a novel computerized method for optimal fitting of roll-over shapes of the lower limb during walking. Gait data of a healthy individual from Winter's book was used …
