Faculty, Staff and Student Publications

Acute myeloid leukemia (AML) is a hematologic malignancy with a poor prognosis, often presenting with systemic and extramedullary manifestations. Leukemia cutis (LC), the infiltration of leukemic cells into the skin, is a rare and clinically significant complication of AML. It often signals extramedullary disease involvement, may precede systemic relapse, and is associated with poor survival outcomes. We report the case of a 36-year-old female with AML who developed recurrent, reddish-brown nodular skin lesions on the face, trunk, and extremities, consistent with LC. Despite achieving initial remission with induction and consolidation chemotherapy, she experienced early LC recurrence, pancytopenia, hepatobiliary dysfunction, and …

Department of Pharmacology, Physiology, and Cancer Biology Faculty Papers

Low-dose aspirin is recommended for prevention of hypertensive disorders of pregnancy (HDP) and preterm birth (PTB) in high-risk pregnancies. There is limited data on factors impacting aspirin response in pregnancy. We aimed to evaluate predictors of aspirin response and association with pregnancy outcome with a prospective study of high-risk pregnancies taking 81 mg aspirin daily. Aspirin response was evaluated with Platelet Function Assay-100 (PFA-100) epinephrine closure time at baseline (< 16 weeks' gestation), follow-up 1 (2-4 weeks after aspirin initiation), and follow-up 2 (28-32 weeks gestation). Multivariable regression was used to identify factors associated with PFA-100 at each visit, and results presented with beta coefficient (B) and confidence interval. The median difference (MD) in PFA-100 in those with and without HDP or PTB was compared. Results included 108 who completed follow-up 1 and 96 who completed both visits with > 75% adherence. PFA-100 was increased from baseline at follow-ups 1 and 2 (MD 37 (27-49); MD 26 (15.5-38.5) respectively). At follow-up 1, obesity (B = -30 (-53 to -7) seconds), …

Faculty, Staff and Student Publications

Pro-energetic effects of functionalized, oxidized carbon nanozymes (OCNs) are reported. OCNs, derived from harsh acid oxidation of single-wall carbon nanotubes or activated charcoal are previously shown to possess multiple nanozymatic activities including mimicking superoxide dismutase and catalyzing the oxidation of reduced nicotinamide adenine dinucleotide (NADH) to NAD+. These actions are predicted to generate a glycolytic shift and enhance mitochondrial energetics under impaired conditions. Impaired mitochondrial energy metabolism is increasingly recognized as an important facet of traumatic brain injury (TBI) pathophysiology and decreases the efficiency of electron transport chain (ETC)-coupled adenosine triphosphate (ATP) and NAD+ regeneration. In vitro, OCNs promote a …

Faculty, Staff and Student Publications

This case report details the successful use of over-the-counter resveratrol and CurQ+ in a five-year-old with pseudoachondroplasia (PSACH), a severe dwarfing condition caused by mutations in cartilage oligomeric matrix protein (COMP). Disproportionate short stature, abnormal joints, joint deformities, and pain starting in early childhood are characteristic findings. Adult treatments include non-steroidal anti-inflammatory drugs (NSAIDs) and joint replacement to manage joint pain. Childhood pain goes largely untreated given the concern of daily use of NSAIDs in the very young. Recently, resveratrol has been shown to reduce pain and CurQ+ improves growth in a mouse model of PSACH. The use of these …

Research outputs 2022 to 2026

Background/Objectives: Observational studies suggest a link between vascular calcification and dementia or cognitive decline, but the evidence is conflicting, and the underlying mechanisms are unclear. Here, we investigate the shared genetic and causal relationships of vascular calcification—coronary artery calcification (CAC) and abdominal aortic calcification (AAC)—with Alzheimer’s disease (AD), and five cognitive traits. Methods: We analyse large-scale genome-wide association studies (GWAS) summary statistics, using well-regarded methods, including linkage disequilibrium score regression (LDSC), Mendelian randomisation (MR), pairwise GWAS (GWAS-PW), and gene-based association analysis. Results: Our findings reveal a nominally significant positive genome-wide genetic correlation between CAC and AD, which becomes non-significant after …

Detection Of Chromosomal Mosaicism- The Importance Of Karyotyping And Fish, Allison Kalinousky, Jennifer Roberts, Madeeha Alikhan, John Herriges, Lei Zhang, Elena Repnikova

Posters

Introduction: The use of whole-exome/whole-genome sequencing for the detection of sequence-level variants and copy number variations (CNV) is increasingly being adopted as a primary testing method for genetic disease diagnosis by many institutions. Additionally, long-read sequencing is a promising technique to capture not only sequence level variants and CNVs but also structural chromosomal abnormalities. Significant progress has been achieved in this field; however, the detection of chromosomal mosaicism, including numerical gains and losses, rings, markers, and structural rearrangements – particularly those that are lineage-specific or exist at low levels – might still pose challenges with these emerging technologies. Furthermore, differentiating …

Contraceptive Hormone Influences On The Role Of Primary Reinforcement And Reinforcer-Enhancement In Nicotine Self-Administration, Kathleen Robin Mcnealy

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

Hormonal contraceptives contain a synthetic estrogen (e.g., ethinyl estradiol/EE) and/or a synthetic progestin (e.g., levonorgestrel/LEVO) and can exacerbate nicotine intake. However, whether altered intake reflects changes in nicotine reinforcement or enhancement by nicotine of co-occurring reinforcers is unknown. This reinforcer-enhancement effect is evidenced in rats when nicotine self-administration is increased by the presence of a visual stimulus (VS) reinforcer. This dissertation examined the effects of EE and LEVO on nicotine reinforcement and reinforcer-enhancement in ovary-intact female Sprague-Dawley rats. Rats were implanted with a jugular catheter and assigned to receive daily injections of EE (Vehicle, 0.125 [Low], or 0.18 [High] μg/day; …

Evaluating Dry Air Personnel Decontamination Of Methyl Salicylate As A Chemical Agent Surrogate In Extreme Cold Environments To Reduce Airborne Risks Using A Manikin, Lance E. Campbell

Theses and Dissertations

This research investigated a mobile air shower as an alternative to water washing for personnel chemical decontamination in Arctic environments, where traditional methods like disrobing and rinsing are impractical. Interest in Arctic operations has grown with recent U.S. military focus on strategic advancements by Russia and China, yet research on air shower effectiveness for chemical decontamination remains limited. This study examined whether a commercial off-the-shelf air shower could effectively decontaminate methyl salicylate (MES), a surrogate for chemical warfare blister agents, from a manikin outfitted in military cold-weather gear. Researchers used a ppbRAE 3000 photo-ionization detector to measure MES concentrations following …

Wmh Contributions To Cognitive Impairment: Rationale And Design Of The Diverse Vcid Study, Charles Decarli, Kumar B Rajan, Lee-Way Jin, Jason Hinman, David K Johnson, Danielle Harvey, Myriam Fornage

Faculty, Staff and Student Publications

As awareness of dementia increases, more individuals with minor cognitive complaints are requesting clinical assessment. Neuroimaging studies frequently identify incidental white matter hyperintensities, raising patient concerns about their brain health and future risk for dementia. Moreover, current US demographics indicate that ≈50% of these individuals will be from diverse backgrounds by 2060. Racial and ethnic minority populations bear a disproportionate burden of vascular risk factors magnifying dementia risk. Despite established associations between white matter hyperintensities and cognitive impairment, including dementia, no study has comprehensively and prospectively examined the impact of individual and combined magnetic resonance imaging measures of white matter …

Exploring Oxylipins In Host–Microbe Interactions And Their Impact On Infection And Immunity, Robert J. Neff, Christopher D. Radka

Markey Cancer Center Faculty Publications

Plasma lipids are essential components of biological systems, transported through interactions with proteins to maintain cellular functions. These lipids exist in various forms, such as fatty acids, glycerolipids, glycerophospholipids, sphingolipids, sterols, and prenol lipids, derived from dietary intake, adipose tissue, and biosynthesis. While the association between certain fatty acids and cardiovascular diseases has been widely recognized, polyunsaturated fatty acids (PUFAs) exhibit cardioprotective effects, reducing risks of arrhythmias and heart-related mortality. This is due to their role in the production of eicosanoids, which modulate inflammation. Chronic inflammation, particularly in obesity, is significantly influenced by fatty acids, with saturated fatty acids promoting …

Open-Hybrid Aortic Stent Placement For Recurrent Coarctation In Complex Single Ventricles, Andrew K Morse, Blaz Podgorsek, Julija Dobrila, Zachary A Cerra, Kiran K Mallula, Muhammad S Khan, Christopher E Greenleaf, Jorge D Salazar, Damien J Lapar, Peter C Chen

Faculty, Staff and Student Publications

Recurrent coarctation of the aorta in patients with hypoplastic left heart syndrome requires timely intervention to limit ventricular dysfunction and atrioventricular valve regurgitation. Current strategies include catheter-based intervention in adequately sized patients or surgical arch augmentation at the time of a concomitant operation. We report an open-hybrid surgical technique with placement of a balloon-expandable stent that can later be expanded to an adult size as the patient grows. Limiting the arch dissection reduces the risk to the left recurrent laryngeal nerve and shortens anterograde cerebral perfusion time.
