Rocatinlimab As A Novel Treatment Strategy For Atopic Dermatitis, Haylee Whyde, Evan Blazek, Macy Davis, Parker George, Alex Lowery, Connor Dains, Brenna Hissong, David Koh

Pharmacy and Wellness Review

Atopic dermatitis is a common chronic inflammatory skin disease that affects millions of children and adults in the United States. Atopic dermatitis is characterized by recurrent pruritus, erythema, and relapsing symptoms that can significantly impair quality of life. The pathophysiology of atopic dermatitis involves epidermal barrier dysfunction, immune dysregulation, and genetic susceptibility. Atopic dermatitis guidelines follow a stepwise approach that begins with a severity assessment, trigger avoidance, and nonpharmacologic and pharmacologic treatments. First-line therapies include topical corticosteroids (TCSs), topical calcineurin inhibitors (TCIs), and emollients. Crisaborole and topical ruxolitinib are used for mild-to-moderate disease when prior therapy has been inadequate. Monoclonal …

Ankle Dorsiflexion Is A Primary Influence On Single Limb Landing Stability Regardless Of Menstrual Cycle Chase, Olivia Matrulli

Honors Theses

Context: Hormonal fluctuations associated with the menstrual cycle contribute to modifications in joint laxity. Conflicting evidence supports increased ligamentous injury risk and altered postural control in response to these cyclic changes. Objective: To quantify changes in passive joint flexibility and dynamic postural control across the menses and luteal phases of the menstrual cycle. Design: Repeated measures. Setting: Research laboratory. Participants: Thirteen healthy females (20 [1] y, 1.62 [0.06] m, 67.42 [11.75] kg) with a regular menstrual cycle over the last twelve months volunteered. Interventions: Participants performed five static flexibility tests and three single-leg drop landings onto a force plate with …

The Marathon Without Running: Experiencing A Runner's Sensorial Journey, Harin Kim

Masters Theses

The marathon is defined not by motion alone, but by the changing conditions a body moves through—and remains within—over time. Breath, cadence, heat, sound, crowd compression and attention fluctuate, producing phases that structure the race from within. These interior states are difficult to access by spectators from the sidelines, yet they are precisely what shape the runner’s experience.

This thesis begins with a simple but unconventional question: How can an exhibition translate the runner’s physical sensations and emotions into a multidimensional experience for spectators who do not run? Through a sequence of pop-up exhibitions placed along the New York City …

The Impact Of Tgfβ Conditioning And Socs3 Expression On Cytokine Signal Transduction And Inflammatory Gene Expression In Fibroblasts, Morgan Anderson-Crannage

NYMC Student Theses and Dissertations

Inflammation is a major driver in many aspects of recessive dystrophic epidermolysis bullosa (RDEB) pathology, including impaired wound healing, fibrosis, and potentially cutaneous squamous cell carcinoma development. Fibroblasts, as key stromal cells in the dermis, are responsible for orchestrating inflammatory responses through the secretion of cytokines and chemokines upon stimulation with IL-1α or IL-6. Suppressor of Cytokine Signaling 3 (SOCS3) functions as a negative feedback regulator of cytokine signaling and has emerged as a key modulator of inflammatory responses in immune cells and fibroblasts. Transforming Growth Factor Beta (TGFβ), a known driver of fibrosis in RDEB, has been implicated in …

P300/Cbp Inhibition With Inobrodib In Combination With Gilteritinib And Venetoclax Targets Leukemia Stem Cells In Epigenetic Mutant Aml, Melanie L. Goetz, Jennifer S. Romer-Seibert, Amanda M. Versace, Scott Kogan, Chetan Jeurkar, Robert L. Bowman, Nigel Brooks, Kris Frese, Sara E. Meyer

Department of Pharmacology, Physiology, and Cancer Biology Faculty Papers

Acute myeloid leukemia (AML) is a fatal blood cancer with cytotoxic chemotherapy offering at best 25% 5-year survival. While targeted BCL2 and FLT3 inhibitors venetoclax and gilteritinib are used upfront in the treatment of a subset of adult patients with AML and help to extend the survival of some patients, a curative treatment combination with minimal side effects has yet to be discovered. We find that use of the dual histone acetyltransferase p300/CBP bromodomain inhibitor CCS1477 (inobrodib), together with venetoclax and gilteritinib, virtually eliminates leukemia stem cells in an aggressive preclinical model of DNMT3A/FLT3-mutant AML by impairing pro-oncogenic survival and …

Thermal Physiological Ecology Of The Relict Leopard Frog At Hot And Cold Springs, Robert P. Pelletier Iii

UNLV Theses, Dissertations, Professional Papers, and Capstones

The relict leopard frog (Rana onca) once ranged across drainages in southern Nevada, northwestern Arizona, and southwestern Utah. Following a decline, the species only persisted in a few geothermally influenced hot springs, which led to the perspective that hot springs were high-quality habitat. Rana onca has been under intensive, multiagency management and the species has been translocated to establish additional populations, including at cold-water sites. Three research studies are presented into the thermal physiological ecology of R. onca with the aim of informing conservation strategy. The research was focused at a thermally influenced hot spring and a cold-water spring to …

Neuroprotective Effects Of Estradiol And Genistein And Interactions With Aromatase Inhibitions Post Cerebellar Lesion In Male Zebra Finches, Grace E. Thompson, Anthony P. Irovic

Honors Theses

Across vertebrates, peripheral and brain-derived estradiol (E₂) promotes neuroplasticity. After injury, E₂ can be derived locally from testosterone via aromatase (AROM), an enzyme that is upregulated in glia at the site of neural injury. E₂disrupts testicular function and elevates cancer and stroke risk, primarily via binding to estrogen receptor alpha (ER α). Genistein (GEN), a phytoestrogen, is similar to E₂ but binds preferentially to estrogen receptor beta (ER β). It may offer neuroprotection without adverse effects of E₂. We used adult male zebra finches (ZF) to model neuroprotective effects of E_{2 …}

A Series Of Investigations On The L. Cornutus Host System And Bivesiculid Sp. Cercariae, Briana K. Zaffiro

All HCAS Student Capstones, Theses, and Dissertations

Rising global temperatures are likely modulating parasite-host interactions, yet the direction and magnitude of these changes remain uncertain. Rarely are these interactions viewed from both a host and parasite perspective. Using both CT_max, or Critical Thermal Maximum, and Clark-type polarographic oxygen microelectrodes, the physiological metabolic effects are investigated. CT_max is examined in Common Shiners, Luxilis cornutus, and is shown to be modulated by parasitism: uninfected fish had the highest CT_max average of 37.0°C, whereas heavily infected fish had decreased CT_max averaging 35°C. Prior to the parasite metabolic investigation, a suitable medium was determined, as …

Beat Behind The Bark: Investigating The Effects Of Music Tempo On Canine Physiological And Psychological States, Marley Lanier

Honors Theses

This study explores how the tempo of music, measured in beats per minute (BPM), affects dogs' heart rate and oxytocin levels, adding to past research that shows that music affects physiological and behavioral states in dogs. Being able to understand these effects holds practical implications for improving overall well-being in canines in environments such as homes, shelters, and clinical environments. Using a within-subjects design, the dogs were exposed to slow and fast versions of one instrumental track, along with a white noise baseline condition before each randomized condition. Heart rate was recorded continuously throughout the session, and oxytocin saliva samples …

Which Energy Expenditure Equation Is Most Accurate In A Field-Based Setting?, Merrill C. Ward

All Graduate Reports and Creative Projects, Fall 2023 to Present

Several energy expenditure prediction equations for walking on varied terrain exist; however, these predictions are often theoretical and have not undergone rigorous field testing for accuracy. Field research on this topic is sparse. The aim of this study was to determine if any existing energy expenditure prediction equations are accurate in a field-based setting with load and gradient being taken into account (i.e., under conditions that are most applicable to day hiking). This was done by directly measuring relative VO₂ (ml/kg/min) of study participants and comparing these direct measurements to the values generated from the existing prediction equations. Fifteen …

The Beat Behind The Bark: Investigating The Effects Of Music Tempo On Canine Physiological And Psychological States, Marley Lanier

Poster Presentations

Music is a universal component of human culture that has been demonstrated influencing emotional, cognitive, and physiological responses, specifically heart rate and hormonal responses (Mehr et al., 2019; Trappe, 2012). Recently, this research has expended to explore how music may affect non-human animals, particularly dogs, due to their roles as therapy animals, service animals, and human companions (Lindig et al., 2020; Gee et al., 2021). Being able to understand how music influences canine stress and relaxation hold important applications in environments such as shelters, veterinary clinics, and at home. One important feature of music is tempo, or beats per minute …

Morphological Variation Of Lingual Glands In Wild American Alligator (Alligator Mississippiensis) Populations, Benjamin Angalet

Master's Theses

American alligators (Alligator mississippiensis) inhabit diverse aquatic ecosystems including freshwater wetlands, swamps, and estuarine rivers. As apex predators, their physiological resilience has implications for ecosystem stability and long-term conservation. With projected sea-level rise and increasing saltwater intrusion into coastal freshwater habitats, understanding the osmoregulatory capacity of alligators is increasingly important. Unlike marine-tolerant crocodilians such as the saltwater crocodile (Crocodylus porosus), which possess specialized salt-secreting lingual glands in addition to renal and cloacal mechanisms, the morphology and physiological significance of lingual glands in wild American alligators remain poorly understood. This study examined lingual gland morphology and plasma …

Comparative Biomechanics: Blattodea Antennal Morphology And Physiology, Lucas W. Marsh

All Theses

Equipped with muscle-free antennae, many insects can twist and bend their antennae on demand. We hypothesized that hemolymph circulating through the antennae provides pressure that facilitates twisting and bending and provides a feedback control channel for tactile sensing in insects. To test this hypothesis, we conducted a thorough morphological and physiological analysis of antennae in three Clades of Blattodea. We studied morphology by evaluating the distinguishable features of the body and antenna, as well as the internal structure of the antennal lumen. Then, in a series of experiments on live cockroaches, we measured blood pressure along the antenna. This was …

Understanding The Role Of Toxs As A Bile Sensing Component Of The Toxrs Virulence Regulatory System In Vibrio Spp., Minje Kim

Dartmouth College Ph.D Dissertations

Pathogenic Vibrio bacteria, such as V. cholerae and V. parahaemolyticus, colonize in the human small intestine to cause severe gastrointestinal disease. During the infection, these bacteria encounter bile salts, antimicrobial cholesterol metabolites secreted into the intestine. Pathogenic Vibrio species have evolved to utilize bile salts as signals to regulate virulence. The signaling depends in part on ToxRS, a conserved co-component transmembrane transcription regulator. ToxRS consists of the transcription factor ToxR and its membrane-tethered binding partner ToxS. ToxS is required for ToxR stability and full transcriptional activity. Although bile salts are known to influence ToxRS-dependent virulence gene expression, the molecular …

Veratridine Suppresses Rictor-Mtorc2 Signaling Pathway In Colon Cancer Patient-Derived Xenograft Cells, Morgan Daniel Montgomery

Honors Thesis

Colorectal cancer (CRC) remains the second deadliest and fourth most common cancer in the world. The metastatic form of CRC is especially devastating due to a lack of effective and safer therapeutic options. Another challenge includes an increasing number of younger patients. Among critical signaling pathways overactivated in CRC, mTORC2 plays a key role in the progression of metastatic CRC, yet there is no selective mTORC2 inhibitor in the clinic. Interestingly, a natural plant alkaloid from the Veratrum genus, Veratridine (VTD), shows promise as VTD can upregulate UBXN2A, a colon-specific tumor suppressor protein. UBXN2A works with E3 ligases to ubiquitinate …

Evaluating Inner-Tainment With A Ghetto Perspective For Positive Thought Adjustment In Ghetto Communities, Shontae L. Graham

Doctoral Dissertations and Projects

Environmental challenges and disadvantages impact cognitive scripts and develop persistent frustration. Frustration is both mental and physical and can be negative or positive. It evokes emotion, which is prompted by memory and its associated level of importance. The integration of emotion, memory, and imagination can set the stage and create an act to transition negative frustration and align past experiences with new perspectives. This study used a qualitative Interpretive Phenomenological Analysis approach to investigate the use of self-scripted enactment as a self-help technique for positive thought adjustment. The technique is called Inner-tainment and was used to determine if there were …

Acute Effects Of Olympic Lifting Post-Activation Potentiation On Baseball Pitching Velocity And Ball Flight: A Crossover Study, Brent Hauser Pourciau

Doctoral Dissertations and Projects

This quantitative study evaluated the acute effect of an Olympic lifting-based post-activation potentiation (PAP) warm-up on fastball performance in collegiate baseball pitchers. Using a randomized, counterbalanced within-subjects crossover design (N = 13), each participant completed two warm-up conditions in a single indoor session: (a) a standard dynamic baseball warm-up and (b) the same standard warm-up followed by a brief Olympic-lifting PAP sequence (1 x 3 clean pulls at 80% predicted one-repetition maximum [1RM], 1 x 3 power cleans at 80% predicted 1RM, and 1 x 3 power jerks at 60% predicted 1RM, with 2-minute rests between sets) and a 3-minute …
