Selective Excited-State Dynamics In A Unique Set Of Rationally Designed Ni Porphyrins, Brian Pattengale, Qiuhua Liu, Wenhui Hu, Sizhuo Yang, Peilei He, Sir Lawrence Tender, Yingqi Wang, Xiaoyi Zhang, Zaichun Zhou, Jian Zhang, Jier Huang

Chemistry Faculty Research and Publications

In this work, we report the design and photophysical properties of a unique class of Ni porphyrins, in which the tert-butyl benzene substituents at the meso positions of the macrocycle were tethered by ethers with alkyl linkers. This not only results in the permanently locked ruf distortion of the macrocycle but also enables the engineering of the degree of distortion through varying the length of alkyl linkers, which addressed the complication of uncertainty in the specific structural distortions that has long plagued the porphyrin photophysical community. Using advanced time-resolved optical and X-ray absorption spectroscopy, we observed tunability in the …

Here, we studied the effect of antimicrobial agents; a recently developed peptidomimetics E107-3 and colistin as well as the N-terminal helix H0, of Endophilin A1 on the lipid bilayer.

It is important to discern the interaction mechanism of antimicrobial peptides with lipid membranes in battling multidrug resistant bacterial pathogens. We study the modification of structural and mechanical properties with a recently reported peptidomimetic on lipid bilayer. The compound referred to as E107-3 is synthesized based on the acylated reduced amide scaffold …

Understanding Trans Racialized Youth Autonomy In Health Care Decision Making In Ontario, Gitanjali Natasha Lena

LLM Theses

This thesis re-evaluates the concept of autonomy and the possibilities for trans racialized youth to practice it in current health care decision making contexts. After discussing access to health care in Ontario for this demographic using diverse research, an analytical foundation is laid using legal pluralism, relational autonomy, transgender theory and disidentification theory. The study uses Photovoice with trans racialized youth to produce visual texts analysed using thematic network analysis. Secondly, the study considers how together, law and medicine discursively work to encourage law-makers and health care providers to undermine the autonomy of trans racialized youth. Authoritative diagnostic and clinical …

The Rise And Fall Of Focused Deterrence Initiatives, Chandra Lynore Joseph

LSU Doctoral Dissertations

Following the national uptick of violence across the country, societal angst has once again begun to surface. Those in positions of authority began to look to the criminal justice system for ways to address this cyclical issue. Traditionally, applying law enforcement crackdowns and increased penalties and sanctions to the offenders were the main topics of discussion. However, over the last two decades, problem-oriented policing has begun to emerge. Problem-oriented policing works to identify why things are going wrong and to frame responses using a wide variety of often untraditional approaches (Goldstein 1979). One of the problem-oriented frameworks known as the …

Factors Affecting Nest Success Of Colonial Nesting Waterbirds In Southwest Louisiana, Karis A. Ritenour

LSU Master's Theses

As the coastline of Louisiana shifts with global climate change, subsidence, and accelerated sea level rise, important breeding islands for colonial nesting waterbirds are disappearing. In many recent studies flooding has been a leading cause of nest failure for a variety of species, especially those that nest on the ground. I examined the nest success of four species of colonial nesting waterbirds with various nesting strategies on Rabbit Island in southwestern Louisiana during 2017 and2018 by determining nest and fledging success. I monitored 855 nests, including 457 Brown Pelicans nests with an estimated hatch probability of 70%, 270 Forster’s Terns …

Infection Potential Of Rickettsia Felis Via Ingestion, Matthew M. Schexnayder

LSU Master's Theses

Rickettsia felis is the etiologic agent of flea-borne spotted fever (FBSF) in humans and a poorly described cause of fever in animals. It is transmitted by its primary arthropod vector and reservoir host, the cat flea Ctenocephalides felis. Known routes of Rickettsia felis transmission between Rickettsia felis-infected cat fleas and vertebrate hosts include cutaneous bites and contamination of cutaneous wounds with infective flea feces. The bulk of FBSF infections occur in young children in Africa, though infections of people at all ages all over the world have been confirmed. As mammals and young children frequently come into contact …

Influence Of P Fertility On Sweetpotato Rooting During Containerized Transplant Production, Lee T. Rouse

LSU Master's Theses

A market for edible landscape transplants continues to increase for vegetable production in the home landscape. A method for extending the salability of sweetpotato transplants in retail outlets is needed because containerized transplants can develop spiraling roots and deformed storage roots. Implementing traditional techniques to ameliorate container-bound roots before planting in the landscape is not advisable. Altering P fertility is a non-chemical and non-mechanical method for slowing sweetpotato rooting. Therefore, sweetpotato cuttings were planted in 100% sand-filled containers and fertilized at 0, 5, 10, 15, 20, and 31 mg L^-1 using a modified Hoagland solution over a 6-week period. …

Development Of Biological Tools To Promote Rice Health And Growth, Ateet Maharjan

LSU Master's Theses

Sheath blight (ShB - caused by Rhizoctonia solani) and bacterial panicle blight (BPB - caused by Burkholderia glumae) are economically important rice diseases in Louisiana and other rice-growing regions. Fungicides and oxolinic acid are used to manage ShB and BPB, respectively, but these chemical methods are not sustainable economically and ecologically. Besides diseases, plant utilizable nitrogen (N) in the soil is inadequate for optimum crop yield, leading to the use of inorganic fertilizers and making agriculture less sustainable. To develop alternative biological control methods for protecting rice plants from diseases, rice-associated bacteria were screened based on their antagonistic …

Effects Of Silicon And Beneficial Bacteria On Sheath Blight Of Rice And The Microbial Community Of Rice Rhizosphere, Jhonson Leonard

LSU Master's Theses

Sheath blight (ShB), caused by Rhizoctonia solani Kühn, is an economically important soil-borne disease of rice (Oryza sativa) that can cause up to 50 % yield losses. Application of fungicides is the most effective and commonly used method for managing sheath blight. However, the pathogen can develop new resistant strains upon continuous exposure to a fungicide. Moreover, the use of inorganic fungicides is not eco-friendly. The utilization biological control agents (BCAs) can be a more sustainable and safe means of managing ShB. To develop alternate strategies for ShB management, I am exploring the effect of the silicon (Si) …

Assessment Of Excess Thyroid Cancer Risk Following A Hypothetical Radiological Incident In Louisiana And Best-Case Risk Reduction Achieved By Thyroid Blockade, Garrett A. Otis

LSU Master's Theses

Radioactive isotopes of iodine are produced by nuclear power plants as a byproduct of nuclear fission reactions. If these isotopes are released into the environment, such as during a breach of containment, they constitute a health risk to exposed individuals. To mitigate the risk of thyroid cancer due to exposure to radioactive iodine, “iodide prophylaxis,” also known as “thyroid blockade,” can be used, usually by administration of potassium iodide (KI). In some areas of the world, KI has been provided to the general public by their governments as a precautionary measure against potential nuclear power plant incidents. However, in the …

Agricultural Education Teachers' Perceptions And Use Of Environmental Education In Louisiana Schools, Olivia M. Soler

LSU Master's Theses

The purpose of this study was to describe the status of environmental education (EE) in Louisiana high school agriculture classrooms. A census of Louisiana Agriscience Teacher Association (LATA) members was conducted to understand their perceptions, attitudes, and barriers regarding EE implementation. Icek Ajzen’s Theory of Planned Behavior was utilized as the theoretical framework. Data were collected through an online survey research method and analyzed using descriptive statistics. Results suggest that most LATA members incorporate EE into their curriculum relatively sparingly, perceive EE to be beneficial for students, and are in need of funding to incorporate EE into their curriculum as …

Urban Landscape In Mcewan's Narrative Representation Of Berlin, Barbara J. Puschmann-Nalenz

CLCWeb: Comparative Literature and Culture

In her article "Urban Landscape in McEwan's Narrative Representation of Berlin," Barbara J. Puschmann-Nalenz discusses the image of Berlin created in Ian McEwanﹸs novel The Innocent (1990) and the chapter titled "Berlin" in Black Dogs (1992). It starts from the hypothetical statement that while British literary fiction set in Berlin is rare after 1970 the genres of spy and detective novel, where crime and violence take center stage, shape the image of the city in highbrow narratives as well. The perspectivization of the cityscape, including its monuments, through the protagonists fundamentally influences its image. In The Innocent the limited view …

Opportunities And Challenges For Community-Based Ecotourism Development: The Case Of Alatish National Park, Northwest Ethiopia, Kassegn Berhanu

Contrary to traditional forms of tourism such as mass tourism, ecotourism has widely been recognized as an economic diversification and developmental tool, and an appropriate approach for conservation of natural resources for destinations with tourism heritage possessions as it provides protection and economic incentives. The aim of this study is to assess opportunities and challenges for community-based ecotourism development. A mixed research approach was devised and a cross-sectional research design was used. Tools of primary data collection were questionnaires, focus group discussions, interviews and observation checklists. Secondary data were collected from related articles, research and documents obtained from offices. Quantitative …

Listen To The Voices Of Maasai Women In Kenya: Ensuring The Well-Being Of Their Families Through Collective Actions, Taeko Takayanagi

International Journal of African Development

This is an ethnographic study that provides insight into grassroots activities managed by Maasai women leaders in the Narok area of Kenya. Four women’s narratives were used as a basis of analysis to demonstrate their roles in facilitating grassroots activities to improve village women’s well-being despite gender discrimination and multidimensional constraints. The women’s group leaders commented that low literacy had a negative influence on Maasai women’s development; however, the issue of illiteracy could be overcome through cooperative learning during women group activities in their village. The results showed that the women’s group leaders played a facilitative role in improving women’s …

Alkynylnicotinaamide-Based Compounds As Abl1 Inhibitors With Potent Activities Against Drug-Resistant Cml Harboring Abl1(T315i) Mutant Kinase, Alyssa Lambrecht

Purdue Undergraduate Research Conference

Chronic Myeloid Leukemia makes up about 10% of all leukemia diagnoses. Although the 5-year survival rate has increased from 6% to 90% in the last 30 years from the introduction of imatinib, there are several mutated forms of the cancer that are resistant treatment. Treatments such as Ponatinib can be used to treat CML patients that harbor the T315I mutation, but they have toxic effects on the body. Safer treatments need to be discovered to inhibit the proliferation of these resistant lines by inhibiting the activity of proteins and mutated proteins. Through research done utilizing cell cultures of CML lines …

Association Between Ketogenic, Vegan, And Paleo Diets And Dental Biofilm Formation In Vitro, Kynnedy Kelly

Purdue Undergraduate Research Conference

The purpose of this study was to investigate the association between three lifestyle diets (ketogenic, vegan, and paleo) and dental biofilm formation in vitro. This study was set up in glass test tubes containing hydroxyapatite discs, an artificial saliva and 5 percent natural saliva combination, Streptococcus mutans, and Lactobacillus acidophilus. Food items from three meals (breakfast, lunch, and dinner) were selected for each diet, blended to form a consistent mixture, and added to 25 percent final volume in the test tubes. Biofilms were grown for 48, 60, and 72 hours. Biofilm density was measured quantitatively using a crystal violet assay. …

Aligning Ocean Plastic Pollution And Human Health A Co-Benefits Approach, Karyn Morrissey Dr

Journal of Ocean and Coastal Economics

.

The environmental literature has begun to consider the impact of environmental problems on human health. This realization serves both as a means to provide scientific evidence to consider the environment and public health jointly. This approach also increases recognition of the environment where stakeholders have not understood the links between environmental and human health. The oceans and seas play an important role in human health, through the provision and quality of the air that we breathe, the food we eat, the water we drink, while offering economic and recreational opportunities which enhance public health. However, the links between human …

The Influence Of Intersectionality On Bullying, Teen Dating Violence, And Suicide Risk Among Bisexual Adolescents, Ariel Uniqua Smith

Open Access Dissertations

Suicide is a significant health problem for sexual minority youth (SMY) in general, and for bisexual youth, who currently have the highest risk for suicide compared to lesbian/gay and heterosexual adolescents in the U.S. Bisexual youth experience “bisexual-specific” stigma and discrimination due to their sexual orientation, and both stigma and discrimination have been linked to increased suicidality and negative mental health outcomes among bisexual individuals. This cross-sectional, descriptive study is guided by the Intersectional Minority Stress theoretical model and uses a secondary analysis of pooled 2015 and 2017 national YRBSS data to examine three specific aims. All analyses are conducted …

Amigeist: A New Extreme Love Phenomenon, Jeffrey Sundberg

International Journal of Transpersonal Studies Advance Publication Archive

Falling in love may begin with an inescapable, uncontrollable, transformative experience of intense emotions and intrusive thoughts, such as limerence. Romantic love researchers have tended to lump extreme love into pathology. Transpersonal psychology was chosen as the lens to examine an extreme occurrence of falling in love for its transformational and spiritual potential using a phenomenological approach. Twenty-five U.S. born participants, age 30 or older, reported experiencing a highly intense and deeply significant romantic love occurrence. Results revealed a unique experience with limited correlations to limerence. The new phenomenon is called amigeist, characterized by immediate, intense soul-mate bonding, such as …

Intimations Of A Spiritual New Age: Ii. Wilhelm Reich As Transpersonal Psychologist Part 2: The Futural Promise Of Reich’S Naturalistic Bio-Energetic Spirituality, Harry T. Hunt

International Journal of Transpersonal Studies Advance Publication Archive

This is the second part of a consideration of the later Wilhelm Reich as anticipating a future planetary-wide “New Age” form of this-worldly spirituality in ways overlapping with figures from the same era of Western crisis from the 1930s through the 1950s, including Jung, Toynbee, Bergson, Heidegger, Teilhard de Chardin, and Simone Weil. Where the first part of this treatment of Reich as transpersonal psychologist traced his evolution from his bio-energetic psychotherapy to a Weberian this-worldly mysticism of a universal life energy, his cosmic orgone, with its attendant features of conflicted “spiritual emergency,” this second paper seeks to further develop …

Intimations Of A Spiritual New Age: Ii. Wilhelm Reich As Transpersonal Psychologist. Part I: Context, Development, And Crisis In Reich’S Bio-Energetic Spiritual Psychology, Harry T. Hunt

International Journal of Transpersonal Studies Advance Publication Archive

Wilhelm Reich is the focus of this second in a series of papers on a group of independent figures from the 1930s into the 1950s—also including Jung, the later Heidegger, Toynbee, Bergson, Teilhard de Chardin, and Simone Weil—who in the context of those years of crisis articulated overlapping visions of a future “New Age” spirituality that might in some more distant future serve to balance and even transform a globalizing materialism and disenchantment with traditional religion. The later Reich developed a highly original version of a “vitalistic” transpersonal psychology, as his “religion for the children of the future,” which needs …

Comparative Efficacy Of Novel Endolysins In Queso Fresco, Daniella Smith, Maxwell J. Holle, Dr. Michael Miller

PRECS student projects

Listeria monocytogenes is problematic for the manufacturing, storage, and consumption of ready-to-eat foods. This bacterium may cause listeriosis upon consumption often with deadly complications. Queso Fresco (QF), a pasteurized Hispanic-style fresh cheese (HSFC), has been shown to support the growth of L. monocytogenes. QF is the most widely produced and implicated HSFC in the U.S., representing a significant health hazard to at risk populations such as infants, pregnant women, elderly, and the immunocompromised. The objective of this research project is to evaluate the efficacy of ten novel antimicrobial endolysins in combatting L. monocytogenes contamination in a miniaturized lab-scale queso fresco …

We take advantage of an organism-wide stress response and genetic tools that provide an excellent model for studying how phenotypes are impacted by stress.

Verification Of Successful Kainic Acid Injections In A Temporal Lobe Epilepsy Mouse Model, Adrian J. Garcia, Robbie J. Ingram, Catherine A. Christian

PRECS student projects

Temporal lobe epilepsy (TLE) is the most prominent form of partial epilepsy in adults. Reproductive endocrine comorbidities appear in patients with TLE at significantly higher rates than in the general population. These comorbidities include polycystic ovary syndrome, hypothalamic amenorrhea, hyperandrogenism, irregular menstrual cycle, lower testosterone levels, hypogonadism, erectile dysfunction, and decreased semen motility. It is believed that gonadotropin-releasing hormone (GnRH) neurons in the hypothalamus play an important role in the development of these comorbidities. The kainic acid (KA) mouse model is used to study epilepsy-associated changes in GnRH neurophysiology. Our lab recently observed that the activity of GnRH neurons is …

Fungal Endophytes Interact With Endophytic Yeast Isolated From Soybean Leaves, Baldemar Basurto, Natalie Christian, Katy Heath

PRECS student projects

Endophytes (endo = inside and phyte=plant) are microscopic fungi that live inside of the leaves of all species of plants and can have beneficial effects on their hosts. Previous work in our lab has shown a significant decrease of Sporobolomyces sp., an endophytic yeast, within soybean hosts exposed to elevated levels of CO₂. Sporobolomyces sp. has certain properties to enable them to act as natural biocontrol agents. This pink yeast may have untapped potential to protect crops from pathogenic organisms. If Sporobolomyces sp. interacts with fungal pathogens, it may have strong effects on other fungal endophytes in the community. The …

Direct Impacts Of Heat Stress On Illinois Soybeans, Jessica O'Connor, Charles Burroughs, Lisa Ainsworth

PRECS student projects

Rising global temperatures are challenging agricultural productivity and can affect soybean yield through many physiological and metabolic processes. Recent regression analyses indicate that soybean yield is depressed in warmer years. This research aims to help determine which processes are affected by heat stress, such as photosynthesis, plant development, leaf area index and yield. The experiment consists of two different varieties of commercial Illinois soybeans, which will be continually heated throughout the growing season in order to compare the physiological characteristics of the soybeans in the heated arrays to those growing in ambient conditions. Data collected on photosynthesis, plant development, leaf …

Effects Of Mycorrhizae On Struvite Dissolution Can Plant-Fungus Mutualism Increase The Viability Of A Sustainable Phosphorus Fertilizer?, Isako Battista Di Tomassi, Erinn Dady, Neha Chatterjee, Andrew Margenot

PRECS student projects

Phosphorus (P) is essential for all organisms. In agriculture, P, nitrogen (N) and potassium (K) are applied in large amounts as fertilizer. Monoammonium phosphate (MAP), a conventional fertilizer, is highly water soluble, causing high P and N concentrations in agricultural runoff, harming aquatic life. Struvite (NH4MgPO4 ·6H2O), a waste-water derived product with potential for use as a P fertilizer; has low water solubility, and phosphorus in struvite is not as accessible to plants as it is in MAP. Arbuscular mycorrhizal fungi (AMF) form mutualisms in which they receive carbon from plants in exchange for other nutrients, and assist in P …
