Design And Development Of Software With A Graphical User Interface To Display And Convert Multiple Microscopic Histology Images, Sayed Ahmadreza Razian, Majid Jadidi, Alexey Kamenskiy

UNO Student Research and Creative Activity Fair

Histological images are widely used to assess the microscopic anatomy of biological tissues. Recent advancements in image analysis allow the identification of structural features on histological sections that can help advance medical device development, brain and cancer research, drug discovery, vascular mechanobiology, and many other fields. Histological slide scanners create images in SVS and TIFF formats that were designed to archive image blocks and high-resolution textual information. Because these formats were primarily intended for storage, they are often not compatible with conventional image analysis software and require conversion before they can be used in research. We have developed a user-friendly …

The Influence Of Metal Contamination On The Fishery Of The Upper Clark Fork River, Montana, Usa, Taylor Gold Quiros

UM Graduate Student Research Conference (GradCon)

Historical mining and mineral processing have led to heavy metal contamination in the flood-plain of the Upper Clark Fork River of western Montana. This contamination has acted as a long-term stressor on the river and its inhabitants, the effects of which can be seen in changes in fish populations along the river's gradient of decreasing metal concentration with distance from the mining source. Understanding the relationships between stressors and ecological responses is essential for management and restoration goals pertaining to ecosystems negatively affected by anthropogenic activities. This study analyzed population distribution of salmonid species based on long-term monitoring and recent …

Alzheimer’s disease (AD) is a genetically complex disease for which nearly 40 loci have now been identified via genome-wide association studies (GWAS). We attempted to identify groups of rare variants (alternate allele frequency <0.01) associated with AD in a region-based, whole-genome sequencing (WGS) association study (rvGWAS) of two independent AD family datasets (NIMH/NIA; 2247 individuals; 605 families). Employing a sliding window approach across the genome, we identified several regions that achieved association p values <10⁻⁶, using the burden test or the SKAT statistic. The genomic region around the dystobrevin beta (DTNB) gene was identified with the burden and SKAT test and replicated in case/control samples from the ADSP study reaching genome-wide significance after meta-analysis (p_meta= 4.74 × 10⁻⁸ ). SKAT analysis also revealed region-based association around the Discs large homolog 2 (DLG2) …

Spin-Nernst Effect In Time-Reversal-Invariant Topological Superconductors, Taiki Matsushita, Jiei Ando, Yusuke Masaki, Takeshi Mizushima, Satoshi Fujimoto, Ilya Vekhter

Faculty Publications

We investigate the spin-Nernst effect in time-reversal-invariant topological superconductors, and show that it provides smoking-gun evidence for helical Cooper pairs. The spin-Nernst effect stems from asymmetric, in spin space, scattering of quasiparticles at nonmagnetic impurities, and generates a transverse spin current by the temperature gradient. Both the sign and the magnitude of the effect sensitively depend on the scattering phase shift at impurity sites. Therefore the spin-Nernst effect is uniquely suitable for identifying time-reversal-invariant topological superconducting orders.

Molecular Biomarkers Of Adult Human And Dog Stress During Canine-Assisted Interventions: A Systematic Scoping Review, Jaci Gandenberger, Erin Flynn, Em Moratto, Ashley Wendt, Kevin Morris

Institute for Human-Animal Connection: Faculty Scholarship

Positive relationships, including those between humans and other animals, particularly dogs, may be a way to reduce stress in humans. However, research into this area is relatively new, and a comprehensive review of the impacts of these interactions on humans and dogs has not been conducted. A scoping review of the scientific literature was conducted to explore what is known about the impacts of canine-assisted interventions on molecular biomarkers (e.g., cortisol and oxytocin) and associated measures (e.g., heart rate and blood pressure) of human and canine stress. As reported across 27 identified studies, canine-assisted interventions have consistently been demonstrated to …

Many Avenues For Spatial Personality Research: A Response To Comments On Stuber Et Al. (2022), Erica F. Stuber, Ben S. Carlson, Brett R. Jesmer

Wildland Resources Faculty Publications

We are grateful for the thought-provoking and forward-looking commentaries (Dingemanse et al. 2022; Mabry 2022; Spiegel and Pinter-Wollman 2022; Vander Wal et al. 2022) in response to our meta-analysis of evidence for consistent among-individual differences in animals’ spatial behaviors (Stuber et al. 2022). A clear consensus is that our demonstration of the prevalence of repeatability across spatial behaviors, and taxa, is only the first step towards identifying the mechanisms and consequences of variation in spatial behavior. Here, we take the opportunity to emphasize key future directions pertaining to uncovering mechanisms, disentangling apparent personality from spatial constraints, and examining additional metrics …

Understanding The Pathogenesis Of Duchenne Muscular Dystrophy Using A Caenorhabditis Elegans Model, Kiley Hughes

Theses and Dissertations

Duchenne muscular dystrophy (DMD) is an x-linked degenerative disease that affects one out of every 3,500 males. This disease is produced by loss of function mutations in the dystrophin gene that results in the absence of the dystrophin protein from muscles and other tissues. Loss of dystrophin leads to progressive muscle weakness, loss of ambulation, and premature death. At the cellular level, patients present with increased sarcoplasmic calcium, loss of sarcomeric integrity, and mitochondrial damage. There is no cure for DMD. Understanding the progression of the disease and developing effective treatments has been hampered by lack of animal models able …

Structure Of The Wilson Disease Copper Transporter Atp7b, Ryan M Bitter, Secheol Oh, Zengqin Deng, Suhaila Rahman, Richard K Hite, Peng Yuan

Open Access Publications

ATP7A and ATP7B, two homologous copper-transporting P1B-type ATPases, play crucial roles in cellular copper homeostasis, and mutations cause Menkes and Wilson diseases, respectively. ATP7A/B contains a P-type ATPase core consisting of a membrane transport domain and three cytoplasmic domains, the A, P, and N domains, and a unique amino terminus comprising six consecutive metal-binding domains. Here, we present a cryo-electron microscopy structure of frog ATP7B in a copper-free state. Interacting with both the A and P domains, the metal-binding domains are poised to exert copper-dependent regulation of ATP hydrolysis coupled to transmembrane copper transport. A ring of negatively charged residues …

Oral Susceptibility To Ivermectin Is Over Fifty Times Greater In A Wild Population Of Anopheles Albimanus Mosquitoes From Belize Than The Stecla Laboratory Reference Strain Of This Mosquito, Staci M. Dreyer, Kelsey J. Morin, Marla Magaña, Marie Pott, Donovan Leiva, Nicole L. Achee, John P. Grieco, Jefferson A. Vaughan

Biology Faculty Publications

Background

The STECLA strain of Anopheles albimanus has been in continuous colony for many years and is the reference strain on which genomic studies for the species are based. Recently, the STECLA strain was demonstrated to be much less susceptible to ivermectin ingested in a blood meal (4-day LC50 of 1468 ng/ml) than all other Anopheles species tested to-date (LC50 values range from 7 to 56 ng/ml). The ability of An. albimanus to survive ingestion of ivermectin at concentrations far beyond that typically found in the blood of ivermectin-treated people or livestock (i.e., 30–70 ng/ml) could invalidate the use of …

Impact Of Early Feeding: Metagenomics Analysis Of The Infant Gut Microbiome, Matthew D. Di Guglielmo, Karl R Franke, Alan Robbins, Erin L Crowgey

Department of Pediatrics Faculty Papers

Background: Different feeding regimens in infancy alter the gastrointestinal (gut) microbial environment. The fecal microbiota in turn influences gastrointestinal homeostasis including metabolism, immune function, and extra-/intra-intestinal signaling. Advances in next generation sequencing (NGS) have enhanced our ability to study the gut microbiome of breast-fed (BF) and formula-fed (FF) infants with a data-driven hypothesis approach.

Methods: Next generation sequencing libraries were constructed from fecal samples of BF (n=24) and FF (n=10) infants and sequenced on an Illumina HiSeq 2500. Taxonomic classification of the NGS data was performed using the Sunbeam/Kraken pipeline and a functional analysis at the gene level was performed …

Evidence For Paracrine Protective Role Of Exogenous Αa-Crystallin In Retinal Ganglion Cells, Madhu Nath, Zachary B Sluzala, Ashutosh S Phadte, Yang Shan, Angela M Myers, Patrice E Fort

Department of Biochemistry and Molecular Biology Faculty Papers

Expression and secretion of neurotrophic factors have long been known as a key mechanism of neuroglial interaction in the central nervous system. In addition, several other intrinsic neuroprotective pathways have been described, including those involving small heat shock proteins such as α-crystallins. While initially considered as a purely intracellular mechanism, both αA-crystallins and αB-crystallins have been recently reported to be secreted by glial cells. While an anti-apoptotic effect of such secreted αA-crystallin has been suggested, its regulation and protective potential remain unclear. We recently identified residue threonine 148 (T148) and its phosphorylation as a critical regulator of αA-crystallin intrinsic neuroprotective …

BACKGROUND: Autosomal-dominant Alzheimer's disease (ADAD) is caused by pathogenic mutations in APP, PSEN1, and PSEN2, which usually lead to an early age at onset (<  65). Circular RNAs are a family of non-coding RNAs highly expressed in the nervous system and especially in synapses. We aimed to investigate differences in brain gene expression of linear and circular transcripts from the three ADAD genes in controls, sporadic AD, and ADAD.

METHODS: We obtained and sequenced RNA from brain cortex using standard protocols. Linear counts were obtained using the TOPMed pipeline; circular counts, using python package DCC. After stringent quality control (QC), we obtained the counts for PSEN1, PSEN2 and APP genes. Only circPSEN1 passed QC. We used DESeq2 to compare the counts across groups, correcting for biological and technical variables. Finally, we performed in-silico functional analyses using the Circular RNA interactome website and DIANA mirPath …

Functional Magnetic Resonance Imaging Data For The Association Between Polygenic Risk Scores For Neuroticism And Reward-Punishment Processing., Heekyeong Park, Katherine L. Forthman, Rayus Kuplicki, Teresa A. Victor, Tulsa 1000 Investigators, Hung-Wen Yeh, Wesley K. Thompson, Martin P. Paulus

Manuscripts, Articles, Book Chapters and Other Papers

Neuroticism as a personality trait represents a heritable risk for psychiatric disorders. The polygenic risk score for neuroticism (N-PRS) is used to study genetic vulnerability to neuroticism. The current data present the association of the genetic risk for neuroticism to neural reward-punishment processing using functional magnetic resonance imaging. N-PRS was computed based on the individual's genotype information and a genome-wide association study on the UK Biobank data. While individuals performed a monetary incentive delay task, their neural activations for upcoming incentives (reward: gain, punishment: loss) were measured in blood oxygen level dependent (BOLD) signals during the delay phase. Multivariate ANCOVAs …

High stromal tumor-infiltrating lymphocytes (sTILs) are associated with an improved pathologic complete response (pCR) and survival in triple-negative breast cancer (TNBC). We hypothesized that high baseline sTILs would have a favorable prognostic impact in TNBC patients without a pCR after neoadjuvant chemotherapy (NACT). In this prospective NACT study, pretreatment biopsies from 318 patients with early-stage TNBC were evaluated for sTILs. Recursive partitioning analysis (RPA) was applied to search for the sTIL cutoff best associated with a pCR. With ≥20% sTILs identified as the optimal cutoff, 33% patients had high sTILs (pCR rate 64%) and 67% had low sTILs (pCR rate …

Old leachate normally has a low organic compound content, poor biodegradability and is hard to biologically treat. The efficacy of tetravalent metal salts as a coagulant and the application of a natural coagulant as a flocculant in landfill leachate treatment is still inconclusive. Hence, this study aimed to evaluate the potential application of tin tetrachloride (SnCl4 ) as the main coagulant and the rubber seed (Hevea brasiliensis) (RS) as the natural coagulant aid as the sole treatment in eradicating highly coloured and turbid stabilised landfill leachate present at one of the old local landfills in Malaysia.
