Medial Temporal Lobe Surface Features And Cognition In Aging Amyloid-Positive Individuals, Jacob Johnston Jun 2024

Medial Temporal Lobe Surface Features And Cognition In Aging Amyloid-Positive Individuals, Jacob Johnston

Undergraduate Honors Theses

Memory consolidation and metabolism are known to differ between amyloid-beta plaque positive (A+) and negative (A-) amnestic Mild Cognitive Impairment (aMCI) and Alzheimer's disease (AD) dementia participants despite similar medial temporal lobe (MTL) volume between groups. Using high-dimensional surface analysis (shape characterization), this study identified structural differences in the medial temporal lobe between A+ aMCI, A+ AD dementia, and amyloid-negative (A-) healthy control groups (CON), specifically in the CA1 and subiculum regions of the hippocampus and entorhinal cortex. Additionally, regional brain surface-based features were correlated with procedural and episodic memory measures, finding positive associations between CA1 integrity and episodic memory …


Malnutrition Alters Protein Expression Of Kndy Neuropeptides In The Arcuate Nucleus Of Mature Ewes, Jennifer F. Thorson, Ligia D. Prezotto Jun 2024

Malnutrition Alters Protein Expression Of Kndy Neuropeptides In The Arcuate Nucleus Of Mature Ewes, Jennifer F. Thorson, Ligia D. Prezotto

Department of Animal Science: Faculty Publications

The neuropeptides kisspeptin, neurokinin B, and dynorphin A are imperative for the pulsatile secretion of gonadotropin-releasing hormone and luteinizing hormone to ultimately regulate reproductive cyclicity. A population of neurons co-expressing these neuropeptides, KNDy neurons, within the arcuate nucleus of the hypothalamus (ARC) are positioned to integrate energy status from afferent neuronal and glial cells. We hypothesized that KNDyexpressing neurons in the ARC of mature ewes are influenced by energy balance. To test this hypothesis, ovary-intact, mature ewes were fed to lose, maintain, or gain body weight and hypothalamic tissue harvested during the luteal phase of the estrous cycle. Fluorescent, multiplex …


A Study Assessing Stress Induction Methods And Regulation Genes, As Well As Cellular Ultrastructure And Automated Image Analysis In Synechocystis Sp. Pcc 6803, Rebekah White Jun 2024

A Study Assessing Stress Induction Methods And Regulation Genes, As Well As Cellular Ultrastructure And Automated Image Analysis In Synechocystis Sp. Pcc 6803, Rebekah White

Theses and Dissertations

In the world of microorganisms, cyanobacteria are a uniquely skilled powerhouse. They participate in global nutrient and carbon cycling. They can photosynthesize, which allows them to use sunlight and carbon dioxide to produce cellular energy. However, photosynthesis involves a lot of molecular interactions where environmental stresses can interfere, increasing the chances of oxidative stress and nutrient imbalances that can amplify deleterious effects. One such stress, iron limitation, is well-studied and its responses in the cell are known. This study assesses the differences between responses when induced by two different iron limitation methods. Then, a specific stress response regulator DspA, also …

Peroxidases are enzymes that reduce reactive oxygen species (ROS) and oxidize organic substances in living cells. The textile industry, wastewater treatment plants, immunological laboratories, and diagnostic laboratories have extensively used horseradish peroxidase for their oxidating needs. This research aims to provide a tool for identifying potentially useful sources of peroxidases in addition to specifically pinpointing a novel peroxygenase in jalapeño seeds. By using two widely accepted peroxidase assays, the guaiacol assay and the fluorophenol assay, fruits of the genus Cucurbita and roots or leaves of the family Brassicaceae were seen to have high peroxidase activity. Additionally, novel peroxygenase activity was …


Hell's Tails: Localizing The Tail Proteins Of The Hyperthermophile-Infecting Virus Ssv1, Jane Arterberry Jun 2024

Hell's Tails: Localizing The Tail Proteins Of The Hyperthermophile-Infecting Virus Ssv1, Jane Arterberry

University Honors Theses

The tail of Saccharolobus spindle-shaped virus 1 (SSV1) has long been thought to be composed solely of viral protein 4 (VP4), but recent SSV1 structural studies have implicated the presence of additional structural proteins C166 and B78 in SSV1's unique tail. The exact locations of these proteins have not been confirmed. Structural proteins VP4 (C-terminus) and B78 are hypothesized to contribute to an adapter region bridging the viral capsid to the tail, whereas C166 is thought to comprise the majority of an internal extended structure, respectively. SSV1 structural proteins lack cysteine residues providing targets to determine their locations in the …

Placental Co-Transcriptional Activator Vestigial-Like 1 (Vgll1) Drives Tumorigenesis Via Increasing Transcription Of Proliferation And Invasion Genes, Heather M Sonnemann, Barbara Pazdrak, Barbara Nassif, Yimo Sun, Lama Elzohary, Arjun S Katailiha, Gregory Lizée

Faculty, Staff and Student Publications

INTRODUCTION: Vestigial-like 1 (VGLL1) is a co-transcriptional activator that binds to TEA domain-containing transcription factors (TEADs). Its expression is upregulated in a variety of aggressive cancer types, including pancreatic and basal-like breast cancer, and increased transcription of VGLL1 is strongly correlated with poor prognosis and decreased overall patient survival. In normal tissues, VGLL1 is most highly expressed within placental trophoblast cells, which share the common attributes of rapid cellular proliferation and invasion with tumor cells. The impact of VGLL1 in cancer has not been fully elucidated and no VGLL1-targeted therapy currently exists.

METHODS: The aim of this study was to …

How the KRAS oncogene drives cancer growth remains poorly understood. Therefore, we established a systemwide portrait of KRAS- and ERK-dependent gene transcription in KRAS-mutant cancer to delineate the molecular mechanisms of growth and of inhibitor resistance. Unexpectedly, our KRAS-dependent gene signature diverges significantly from the frequently cited Hallmark KRAS signaling gene signature, is driven predominantly through the ERK mitogen-activated protein kinase (MAPK) cascade, and accurately reflects KRAS- and ERK-regulated gene transcription in KRAS-mutant cancer patients. Integration with our ERK-regulated phospho- and total proteome highlights ERK deregulation of the anaphase promoting complex/cyclosome and other components of the cell cycle machinery as …

Vertebral Hu Value And The Pectoral Muscle Index Based On Chest Ct Can Be Used To Opportunistically Screen For Osteoporosis, Xiong-Yi Wang, Sheng Pan, Wei-Feng Liu, Yi-Ke Wang, Si-Min Yun

Faculty, Staff and Student Publications

BACKGROUND: Existing studies have shown that computed tomography (CT) attenuation and skeletal muscle tissue are strongly associated with osteoporosis; however, few studies have examined whether vertebral HU values and the pectoral muscle index (PMI) measured at the level of the 4th thoracic vertebra (T4) are strongly associated with bone mineral density (BMD). In this study, we demonstrate that vertebral HU values and the PMI based on chest CT can be used to opportunistically screen for osteoporosis and reduce fracture risk through prompt treatment.

METHODS: We retrospectively evaluated 1000 patients who underwent chest CT and DXA scans from August 2020-2022. The …

Differential censoring, which refers to censoring imbalance between treatment arms, may bias the interpretation of survival outcomes in clinical trials. In 146 phase III oncology trials with statistically significant time-to-event surrogate primary endpoints, we evaluated the association between differential censoring in the surrogate primary endpoints, control arm adequacy, and the subsequent statistical significance of overall survival results. Twenty-four (16%) trials exhibited differential censoring that favored the control arm, whereas 15 (10%) exhibited differential censoring that favored the experimental arm. Positive overall survival was more common in control arm differential censoring trials (63%) than in trials without differential censoring (37%) or …

Looking For The Oldest Diatoms, Karolina Brylka, Sylvain Richoz, Andrew J. Alverson, David J. Conley

Biological Sciences Faculty Publications and Presentations

Paleontological observations of ancient flora and fauna provide powerful insights into past diversity and relationship dynamics between organisms and their environments. Diatoms are globally distributed protists that influence major biogeochemical cycles and sustain oceanic food webs. The fossil diatom record extends 120 million years back to the Early Cretaceous where rare deposits were discovered worldwide and are occasionally represented by diverse communities. However scarce, the taxonomic richness and geographical spread of these diatom communities suggest prior evolutionary events and therefore earlier deposits. To complement the existing fossil information and to discover diatom deposits predating 120 Ma, we examined 33 study …

Physiological And Biochemical Responses Of Maize (Zea Mays L.) Cultivars Under Salinity Stress, Nosheen Iftikhar, Shagufta Perveen, Baber Ali, Muhammad Hamzah Saleem, Mohammad Khalid Al-Sadoon

Turkish Journal of Agriculture and Forestry

Salt stress is a serious threatening factor for cereal crops such as maize (Zea mays L.) by affecting their growth and development. In the current era, the requirement for staple crops is increasing, so it is important to screen out salt-tolerant genotypes. For this purpose, a pot experiment was designed within three replications on ten different genotypes of the maize. The plants were planted in plastic pots and salt stress (0, 40, 70, 100 mM) was maintained. The salt stress induced a noticeable reduction in plant growth traits (shoot length, root length, shoot, root fresh and dry weight, and leaf …

Local Organic And Inorganic Amendments To Improve Table Grape Production In Mediterranean Vineyards Of Southern Türkiye, Semi̇h Tangolar, Simone Priori, Serpi̇l Tangolar, Meti̇n Turan, Erhan Akça

Turkish Journal of Agriculture and Forestry

In the Mediterranean Region, calcareous soils are generally considered to be of low fertility. The use of large amounts of chemicals and irrigation to compensate for low productivity reduces the producer’s net profit and degrades physical and chemical properties of the soils. As a result, the selection of adaptable genotypes is important in agriculturally limited lands. Grapevine is one of the leading crops in the Mediterranean Basin due to its high tolerance to abiotic conditions. However, the fact that the grapevine grows in extreme soils does not mean that such crop does not respond to a good nutritional program, especially …

Turkish Journal of Agriculture and Forestry

Using a bioinformatics approach to identify binding pockets between proteins is a preferable method before modifying the genome to delineate host interactions with viruses. Based on extensive proteomics data in numerous databases, several interaction prediction methods are available to identify binding sites between viruses and hosts at the individual residue level, but little is known about the interaction prediction strategy for plant viruses. Begomoviruses, belonging to the family Geminiviridae, constitute a group of circular single-stranded (ss) DNA viruses that encode multifunctional proteins responsible for viral replication, causing severe diseases in multiple host plants. These viruses usually escape through plant defense …

The purpose of this study is to evaluate the differences between participants in the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) who regularly shop at farmers’ markets and those who do not. We found that regular farmers’ market shoppers tended to consume on average more fruits and vegetables than WIC participants who did …


Deferred Grazing And Sheep At The Break Of Season In South West Western Australia, Department Of Primary Industries And Regional Development, Western Australia Jun 2024

Deferred Grazing And Sheep At The Break Of Season In South West Western Australia, Department Of Primary Industries And Regional Development, Western Australia

Animal production and livestock factsheets

Grazing annual pastures in the first 12 days after germination can lower the productivity of pastures during winter by removing poorly rooted plants, and by reducing plant leaf area to sub-optimal levels. The Department of Primary Industries and Regional Development (DPIRD) recommends deferring grazing of pasture paddocks at the break-of-season until feed on offer is at least 500–800 kilograms of dry matter per hectare (kg DM/ha). At this level, pasture plants are likely to be firmly rooted and have sufficient leaf area to be productively grazed.

Turkish Journal of Agriculture and Forestry

Organic carbon performs essential functions in soils. Soils act as sources or sinks of atmospheric organic carbon. Agricultural management influences soil organic carbon, impacting climate change. One of the crops most vulnerable to climate change is coffee. Brazil is the world's largest coffee producer, with a predominance of management under a conventional system, with sloping terrain and the absence of conservationist practices. The absence of conservationist practices results in an increase in soil loss rates due to water management and carbon emissions, as well as a reduction in coffee production. This paper aimed to estimate soil and organic carbon losses …

Effects Of Nutrient Solution Strength, Pgpb, And Mycorrhizal Inoculation On Growth,Yield, And Quality Of Strawberry, Masoud Haghshenas, Sander H. Van Delden, Mohammad Javad Nazarideljou

Turkish Journal of Agriculture and Forestry

Strawberry (Fragaria × ananassa Duch) cultivation is not without difficulty since its root environment is sensitive to many biotic and abiotic stresses. In addition, production is often phosphate limited, even at relatively high phosphorus levels, as the high fruit yields greatly exceed the capacity of the phosphorus supply by the root system. Arbuscular mycorrhizal fungi (AMF), plant growth promoting bacteria (PGPB), and combinations of both are known to mitigate stress and enhance nutrient uptake, particularly phosphorus. Therefore, we studied the effects of AMF (Glomus mosseae, and Glomus intraradices), PGPB (Azospirillum lipoferum DSM1691, and Pseudomonas fluorescens DSM 50090), and their combinations …
