Contrasting Tick Species Behaviors: A Course-Based Undergraduate Research Experience (Cure), Sara Benham, Shovan Dutta, Rohan Maddamsetti, Clayton Wright, Alena Anderson, David T. Gauthier, Holly D. Gaff

Spora: A Journal of Biomathematics

Tick-borne diseases are on the rise throughout the world, and there is a need to better understand tick behavior in order to identify potential new interventions. Ticks have a complex life history and can survive months off-host. There is a lack of large-scale data on off-host tick behavior, which leaves a gap in understanding of tick biology outside of tick-host interactions. Introducing undergraduate students to authentic research early in their studies can help prepare them for independent inquiry in upper-level classes. To address the student needs and fill gaps in tick research, students in introductory biology courses recorded observations of …

Microwell Assembly Method Using Inkjet Printing On Photopolymer, Hp Inc

Hassenstab, Shayda Azadmanesh, Missy Briardy, Skyler Gerbers, Aliyah Jabenis, Jennifer L. Thompson, Jonathan B. Clayton

Food for Health: Publications

Emerging evidence indicates that antibiotic-induced dysbiosis can play an etiological role in the pathogenesis of neuropsychiatric disorders. However, most of this evidence comes from rodent models. The objective of this study was to evaluate if antibiotic-induced gut dysbiosis can elicit changes in gut metabolites and behavior indicative of gut-brain axis disruption in common marmosets (Callithrix jacchus) – a nonhuman primate model often used to study sociability and stress. We were able to successfully induce dysbiosis in marmosets using a custom antibiotic cocktail (vancomycin, enrofloxacin and neomycin) administered orally for 28 days. This gut dysbiosis altered gut metabolite profiles, …

Cancer Treatment By Targeting Hdac4 Translocation Induced By Microsecond Pulsed Electric Field Exposure: Mechanistic Insights Through Kinases And Phosphatases, Zahra Safaei

Theses and Dissertations

Epigenetic modifications, arising from sub-cellular shifts in histone deacetylase (HDAC) activity and localization, present promising strategies for diverse cancer treatments. HDACs, enzymes responsible for post-translational histone modifications, induce these epigenetic changes by removing acetyl groups from ε-N-acetyl-lysine residues on histones, thereby suppressing gene transcription. Within the HDAC group, class IIa HDACs are notable for their responsiveness to extracellular signals, bridging the gap between external stimuli, plasma membrane, and genome through nuclear-cytoplasmic translocation. This localization offers two significant mechanisms for cancer treatment: nuclear accumulation of HDACs represses oncogenic transcription factors, such as myocyte-specific enhancer factor 2C (MEF2C), triggering various cell death …

Development Of A Xenograft For Annular Repair Using Pulsed Electric Field Exposures For Enhanced Decellularization, Prince Mensah Kwaku Atsu

Theses and Dissertations

Severe back injuries and chronic pain necessitate surgical replacement of damaged intervertebral disc (IVD) cartilage in advanced disease stages. Bovine IVD tissue has been exposed to an upper threshold pulsed electric field (PEF) dose, causing cell death without thermal damage to the tissue. Subsequent PEF exposures at lower magnitudes have accelerated the removal of immunogenic biomolecules though electrokinetic extraction using optimized aqueous solutions. This approach yields a natural scaffold, ready for biocompatibility and mechanical strength assessment. The effects of microsecond pulsed electric fields (µsPEF) on primary bovine AF fibroblast-like cells have been characterized in vitro. PEFs of 10 and 100 …

Faculty, Staff and Student Publications

Harnessing sunlight via photosensitizing molecules is key for novel optical applications and solar-to-chemical energy conversion. Exploiting abundant metals such as iron is attractive but becomes challenging due to typically fast nonradiative relaxation processes. In this work, we report on the luminescence and excited-state reactivity of the heteroleptic [FeIII(pzTp)(CN)3]− complex (pzTp = tetrakis(pyrazolyl)borate), which incorporates a σ-donating trispyrazolyl chelate ligand and three monodentate σ-donating and π-accepting cyanide ligands. Contrary to the nonemissive [Fe(CN)6]3–, a broad emission band centered at 600 nm at room temperature has been recorded for the heteroleptic analogue attributed to the radiative deactivation from a 2LMCT excited state …

We performed a systematic review and meta-analysis of studies that assessed the effect of exercise intervention on models of VaD to provide an unbiased and comprehensive determination of the cognitive function and brain morphology benefits of exercise. Summary; A systematic search in three databases as well as study design characteristics and experimental data extraction were completed in December 2021. We investigated …

Group 14 Metallocene Catalysts For Carbonyl Hydroboration And Cyanosilylation, Haley J. Robertson, Mallory N. Fujiwara, Allegra L. Liberman-Martin

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

A series of six Group 14 metallocene compounds (M = Ge, Sn, Pb) were studied as catalysts for carbonyl hydroboration and cyanosilylation reactions at room temperature. Both bis(pentamethylcyclopentadienyl) and tetramethyldisiloxa[3]metallocenophane compounds were compared. The tin and lead metallocenophanes exhibited the highest reactivity in hydroboration and cyanosilylation reactions. Hammett analysis of aldehyde hydroboration provided a ρ value of 0.73, suggesting a buildup of negative charge during the turnover-limiting step, consistent with the transition state for hydride transfer to the carbonyl center. NMR studies of Lewis acidity indicate that the Ge, Sn, and Pb tetramethyldisiloxa[3]metallocenophane compounds are weak Lewis acids.

The “Integrality” Of Integral Ecology, Jojo M. Fung

Landas

The Integrality of Integral Ecology calls for a rejection of the technocratic paradigm in favor of the relational paradigm that foregrounds the interbeingness of all humankind and other kinds rooted in their inherent values. This relational paradigm advocates the intersectional relations of cultural, economic, social, political ecology, spiritual ecology, and the ecology of daily life. This integrality is grounded in an incarnational theology that the God who has “earthyfied” Godself has sacralized and “eternalized” our common home. In Asia, this integrality is enriched by the Indigenous/Igorot’s earth spirituality, which identifies Kabunian, land, identity, being, and life as a sacred whole, …

Delineating The Mechanism Of Fragility At Bcl6 Breakpoint Region Associated With Translocations In Diffuse Large B Cell Lymphoma, Vidya Gopalakrishnan, Urbi Roy, Shikha Srivastava, Khyati M Kariya, Shivangi Sharma, Saniya M Javedakar, Bibha Choudhary, Sathees C Raghavan

Faculty, Staff and Student Publications

BCL6 translocation is one of the most common chromosomal translocations in cancer and results in its enhanced expression in germinal center B cells. It involves the fusion of BCL6 with any of its twenty-six Ig and non-Ig translocation partners associated with diffuse large B cell lymphoma (DLBCL). Despite being discovered long back, the mechanism of BCL6 fragility is largely unknown. Analysis of the translocation breakpoints in 5' UTR of BCL6 reveals the clustering of most of the breakpoints around a region termed Cluster II. In silico analysis of the breakpoint cluster sequence identified sequence motifs that could potentially fold into …

Sex Differences In A Mouse Model Of Diet-Induced Obesity: The Role Of The Gut Microbiome, Saluda Stapleton, Grace Welch, Lindsay Deberardo, Linnea R. Freeman

Open Access Fund Publications

Recent decades have seen an exponential rise in global obesity prevalence, with rates nearly doubling in a span of 40 years. A comprehensive knowledge base regarding the systemic effects of obesity is required to create new preventative and therapeutic agents effective at combating the current obesity epidemic. Previous studies of diet-induced obesity utilizing mouse models have demonstrated a difference in bodyweight gain by sex. In such studies, female mice gained significantly less weight than male mice when given the same high fat (HF) diet, indicating a resistance to diet-induced obesity. Research has also shown sex differences in gut microbiome composition …
