Identification Of Genes/Genomic Regions Controlling Resistance To Biotic And Abiotic Stresses In Synthetic Hexaploid Wheat, Madhav Bhatta

Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research

Synthetic hexaploid wheat (SHW; 2n=6x=42, AABBDD, Triticum aestivumL.) is produced from an interspecific cross between durum wheat (2n=4x=28, AABB, T. turgidumL.) and goat grass (2n=2x=14, DD, AegilopstauschiiCoss.). It is reported to have a considerable amount of genetic diversity and is a potential source of novel alleles controlling abiotic and biotic stresses resistance and improving wheat quality. Therefore, the first study was to understand the genetic diversity and population structure of SHWs and compare the genetic diversity of SHWs with elite bread wheat (BW) cultivars. The result of this study identified a wide range of genetic diversity within …

Cross-Lingual Diphthong Perception: A Simultaneous Eeg/Fmri Investigation, David Olonzo Sorensen

Theses and Dissertations

Previous research indicates that humans develop a phonological library in infancy. As humans grow into adulthood, their phonological library becomes well established. Upon encountering phonemes from a new language, humans process these phonemes by comparison to their native phonological library. Event-related potentials (ERP), specifically the mismatch negativity, have been shown to indicate that this process of comparing non-native phonemes to our native phonological library is not improved through learning the new language as an adult. An alternative explanation may be that there is an underlying change in the neural generators as the non-native phonemes are learned, but that this change …

Repair And Adaptation Of Aged Skeletal Muscle To Nonpathological Muscle Damage: The Influence Of Macrophage Polarization, Jacob R. Sorensen

Theses and Dissertations

The age-related loss of skeletal muscle mass and function is accompanied by a decline in regenerative capacity. The processes that facilitate healthy muscle repair are complex, involving several phases of degradation and rebuilding of muscle tissue and the surrounding microenvironment. Specifically, myogenic progenitor cells known as satellite cells are the most influential in repairing damaged muscle tissue. Following injury, satellite cells become activated and migrate, proliferate and fuse with mature skeletal muscle fibers to restore homeostasis to the tissue. However, satellite cells do not act in isolation, a robust inflammatory response is necessary to facilitate successful and rapid healing. Macrophages …

3d Printing For Microfluidics, Hua Gong

Theses and Dissertations

This dissertation focuses on developing 3D printing as a fabrication method for microfluidic devices. Specifically, I concentrate on the 3D printing approach known as Digital Light Processing stereolithography (DLP-SLA) in which serially projected images are used to sequentially photopolymerize layers to build a microfluidic device. The motivation for this work is to explore a much faster alternative to cleanroom-based microfabrication that additionally offers the opportunity to densely integrate microfluidic elements in compact 3D layouts for dramatic device volume reduction. In the course of my research, an optical approach was used to guide custom resin formulation to help create the interconnected …

Gis To Address Questions In Forest Ecology And Management, Nicolas Picard

Purdue GIS Day

Geographic Information Systems (GIS) are powerful tools to deal with spatialized issues. As such, they have become routine tools in forestry to delimit forest resources, support the design of forest inventories, map forest resources, and analyze, model and support decision making to sustainably manage forests. Two examples will be provided to show how forest management can benefit from progress in GIS technology. The first one deals with the optimization of forest roads to harvest trees in tropical rainforests. It required the development of heuristics to solve the multiple target access problem in a reasonable time. The second one deals with …

Cd147 As A Potential Therapeutic Target In Glioblastoma Treatment, Beau Adams

All NMU Master's Theses

Glioblastoma (GBM) tumors are the most common and lethal form of cancer in the central nervous system (CNS). GBM tumors appear to contain a mixture of different cell types, which makes them difficult to treat. GBM cells exhibit altered morphology from normal cells on several different levels, which highlights different pathways to potentially target for therapeutic treatments. The human surface glycoprotein CD147, also known as basigin, is expressed at significantly higher levels in GBMs compared to non-neoplastic brain tissue. Furthermore, levels of CD147 expression correlate with brain tumor progression and show the highest expression in GBM. Here, we suppressed tumor …

[Review], Caroline Barreto Vieira, Yanna Reis Praça, Kaio Luís Da Silva Bentes, Paula Beatriz Santiago, Sofia Marcelino Martins Silva, Gabriel Dos Santos Silva, Flávia Nader Motta, Izabela Marques Dorado Bastos, Jaime Martins De Santana, Carla Nunes De Araújo

Harold W. Manter Laboratory of Parasitology: Library Materials

Triatominae bugs are the vectors of Chagas disease, a major concern to public health especially in Latin America, where vector-borne Chagas disease has undergone resurgence due mainly to diminished triatomine control in many endemic municipalities. Although the majority of Triatominae species occurs in the Americas, species belonging to the genus Linshcosteus occur in India, and species belonging to the Triatoma rubrofasciata complex have been also identified in Africa, the Middle East, South-East Asia, and in the Western Pacific. Not all of Triatominae species have been found to be infected with Trypanosoma cruzi, but the possibility of establishing vector transmission …

Modeling Association In Microbial Communities With Clique Loginear Models, Adrian Dobra, Camilo Valdes, Dragana Ajdic, Bertrand S. Clarke, Jennifer Clarke

Department of Mathematics: Faculty Publications

There is a growing awareness of the important roles that microbial communities play in complex biological processes. Modern investigation of these often uses next generation sequencing of metagenomic samples to determine community composition. We propose a statistical technique based on clique loglinear models and Bayes model averaging to identify microbial components in a metagenomic sample at various taxonomic levels that have significant associations. We describe the model class, a stochastic search technique for model selection, and the calculation of estimates of posterior probabilities of interest. We demonstrate our approach using data from the Human Microbiome Project and from a study …

Combining Mass Spectrometry And Nmr Improves Metabolite Detection And Annotation, Fatema Bhinderwala, Nishikant Wase, Concetta Dirusso, Robert Powers

Department of Biochemistry: Faculty Publications

Despite inherent complementarity, nuclear magnetic resonance spectroscopy (NMR) and mass spectrometry (MS) are routinely separately employed to characterize metabolomics samples. More troubling is the erroneous view that metabolomics is better served by exclusively utilizing MS. Instead, we demonstrate the importance of combining NMR and MS for metabolomics by using small chemical compound-treatments of Chlamydomonas reinhardtii as an illustrative example. A total of 102 metabolites were detected (82 by GC-MS, 20 by NMR and 22 by both techniques). Out of these 47 metabolites of interest were identified, where 14 metabolites were uniquely identified by NMR and 16 metabolites were uniquely identified …

Modeling Effects Of Ecological Factors On Evolution Of Polygenic Pesticide Resistance, C. V. Haridas, Brigitte Tenhumberg

School of Biological Sciences: Faculty Publications

Widespread use of pesticides has resulted in the evolution of resistance in many insect pests worldwide, limiting their use in pest control. Effective pest and resistance management practices require understanding of the genetics of resistance and the life history of the pest. Most models for pesticide resistance assume that resistance is monogenic, conferred by a single gene. However, resistance could evolve as a polygenic quantitative trait resulting from the action of several genes, especially when pesticide dose is low. Further, fitness of the pest could be density dependent and might depend upon abiotic factors such as temperature. It is not …

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Natural history collections spanning multiple decades provide fundamental historical baselines to measure and understand changing biodiversity. New technologies such as next generation DNA sequencing have considerably increased the potential of museum specimens to address significant questions regarding the impact of environmental changes on host and parasite/pathogen dynamics. We developed a new technique to identify intestinal helminth parasites and applied it to shrews (Eulipotyphla: Soricidae) because they are ubiquitous, occupy diverse habitats, and host a diverse and abundant parasite fauna. Notably, we included museum specimens preserved in various ways to explore the efficacy of using metabarcoding analyses that may enable identification …

United States Department of Agriculture Wildlife Services: Staff Publications

Using data on waterfowl band recoveries, we identified spatially explicit hotspots of concentrated waterfowl movement to predict occurrence and spatial spread of a novel influenza A virus (clade 2.3.4.4) introduced from Asia by waterfowl from an initial outbreak in North America in November 2014. In response to the outbreak, the hotspots of waterfowl movement were used to help guide sampling for clade 2.3.4.4 viruses in waterfowl as an early warning for the US poultry industry during the outbreak. After surveillance sampling of waterfowl, we tested whether there was greater detection of clade 2.3.4.4 viruses inside hotspots. We found that hotspots …

Counting Members In My League: Mate Value Moderates Economic Effects Of Local Operational Sex Ratio, Zilin Yan

Dissertations and Theses Collection (Open Access)

When local operational sex ratio skews toward a larger proportion of same-sex to opposite-sex individuals, should members of the surplus sex increase or decrease (economic) efforts on reproduction? Past research yielded mixed results. In light of the fact that modern humans are highly mobile and can relocate to communities that may offer better reproductive prospects, it may not always be a given that individuals facing same-sex skewed local community will become current-oriented with regard to reproduction; instead, they may contemplate whether their efforts will pay off and decide whether they prefer to wait for better situations later. The present research …

Lc-Ms/Ms Based Analysis Of Vitamins B3 And B6 In Healthy And Obese Emirati Population, Ghada Rashad Mohamed

Theses

Water-soluble vitamins like Vitamin B3, B6, and B9 are of utmost importance in human health and disease, as they are involved in numerous critical metabolic reactions. Not surprisingly, deficiencies of these vitamins have been linked to various disease states. For example, Vitamin B6 deficiency has been related to many diseases in humans especially in women with type 1 diabetes and in patients with systemic inflammation, liver disease, rheumatoid arthritis, and those infected with HIV. Similarly, derivatives of Vitamin B9 (such as folates), are needed to synthesize, repair, and methylate DNA as well as to act as a cofactor in certain …

Identifying Elderly With Poor Sleep Quality Using Unobtrusive In-Home Sensors For Early Intervention, Xiaoping Ma, W K P Neranjana Nadee Rodrigo Goonawardene, Hwee-Pink Tan

Research Collection School Of Computing and Information Systems

Along with the upward trend in population ageing is the increasing proportion of the elderly population living alone in the community. This group is especially vulnerable as the onset of various physical, social and mental health issues may be more likely and may go undetected. However, smart homes enabled with elderly monitoring and care systems (EMCS) can now be used to alert caregivers of anomalies in the daily living patterns of the elderly. In this study, we focus on the sleep quality as the key living pattern, as it has been shown that poor sleep quality can lead to health …

A Host–Parasite Model Explains Variation In Liana Infestation Among Co‐Occurring Tree Species, Marco D. Visser, Helene C. Muller-Laudau, Stefan A. Schnitzer, Hans De Kroon, Eelke Jongejans, S. Joseph Wright

Biological Sciences Faculty Research and Publications

1. Lianas are structural parasites of trees that reduce the growth, survival and reproduction of their hosts. Given that co‐occurring tree species differ strongly in the proportion of individuals that are infested by lianas (liana prevalence), lianas could differentially impact tree species and thereby influence tree community composition. Surprisingly, little is known about what governs variation in liana prevalence.
2. Here, we apply an approach inspired by disease ecology to investigate the dynamics of liana prevalence over 11 years on Barro Colorado Island, Panama. We followed the fate of 1,938 individual trees from 21 tree species, recording deaths and change in liana …
