Spinal Cord and Brain Injury Research Center Faculty Publications

Cerebral hypometabolism occurs in both traumatic brain injury (TBI) and Alzheimer's disease (AD), but whether these conditions act through distinct or overlapping mechanisms is unclear. TBI disrupts cerebral metabolism via blood–brain barrier damage, altered glucose transporter expression, calcium buffering abnormalities, and oxidative damage to metabolic enzymes. AD-related hypometabolism is linked to amyloid-β (Aβ) effects on mitochondria, including impaired respiration, oxidative stress, and altered mitophagy, fusion, and fission. We tested whether TBI-induced mitochondrial dysfunction exacerbates Aβ-mediated impairment using a closed-head injury (CHI) model in APP/PS1 knock-in (KI) mice. Injuries were delivered at 4–5 months of age, before plaque formation and mitochondrial …

Current Concepts In Hip And Core Assessment To Reduce The Risk Of Acl Injury, Jeremy M. Burnham, Anthony T. Drazick, Ghislain Aminake, Darren L. Johnson, Mary Lloyd Ireland, Brian W. Noehren

Orthopaedic Surgery and Sports Medicine Faculty Publications

Background: Hip and trunk (“core”) muscle dysfunction has emerged as a modifiable contributor to lower-limb biomechanics linked with non-contact anterior cruciate ligament (ACL) injuries. Clinicians increasingly target core stability and control during injury-prevention screening and post-operative rehabilitation programs; however, the literature lacks a focused synthesis of core-directed strategies for ACL injury mitigation. The purpose of this current concepts review is to synthesize current evidence on hip- and core-focused assessment and rehabilitation strategies that may mitigate ACL injury risk.

Design: Current Concepts Review.

Methods: A narrative search of PubMed and Google Scholar (January 2000 – April 2025) identified biomechanical, prospective, interventional, …

Candidate Interaction Partners Of Calpain-5 Suggest Clues To Its Involvement In Neovascular Inflammatory Vitreoretinopathy, Jozsef Gal, Vimala Bondada, Rachel Crasta, Dorothy E. Croall, Calvin P. Vary, James W. Geddes

Spinal Cord and Brain Injury Research Center Faculty Publications

Although calpain-5/CAPN5 is widely expressed in mammals, little is known regarding its functions. Pathogenic mutations of CAPN5 are causal for a devastating autoimmune eye disease, neovascular inflammatory vitreoretinopathy (NIV). To provide insight into both the physiological and pathological roles of CAPN5, it is essential to identify candidate interaction partners and possible substrates. Human SH-SY5Y neuroblastoma cells, transfected with full-length catalytically dead (Cys81Ala) CAPN5-3×FLAG, were used for anti-FLAG co-immunoprecipitation (co-IP) and quantitative proteomics using Sequential Window Acquisition of all THeoretical mass spectra (SWATH-MS). Fifty-one proteins were enriched at least four-fold, p < 0.01, relative to cells transfected with an empty FLAG vector. A high proportion (24/51) of candidate CAPN5 interaction partners are associated with protein quality control, including components of the chaperonin, chaperone, and ubiquitin–proteasome systems. Additional candidate interactors include tubulins, kinases, phosphatases, G proteins, and mitochondrial proteins. CAPN5 interactions for 14 of the candidate proteins were confirmed by co-IP and immunoblotting. Of these 14 proteins, 11 exhibited in vitro calcium-induced proteolysis following co-IP with WT CAPN5-3×FLAG. Impaired calcium-induced proteolysis of co-IP proteins was observed for the pathogenic CAPN5 variants R243L and R289W. Further studies are needed to validate the association of candidate CAPN5 interactors with proteins and complexes suggested by the SWATH-MS and co-IP results, and the possible role of CAPN5 within such complexes. The possible involvement of CAPN5 in protein quality control is relevant to NIV, as defects in protein quality control have been implicated in inherited retinal disorders. Proteomic data are available via ProteomeXchange with identifier PXD068008.

Achter, Gregory Nathaniel Milburn, R. C. Bretherton, K. Kahnert, S. Erbil Bilir, H. Hvid, C. Pyke, F. Gustafsson, L. Adamo, Kenneth S. Campbell, K. M. Herum, A. Lundby

Internal Medicine Faculty Publications

Peripartum cardiomyopathy (PPCM) is a rare form of acute heart failure that develops in women toward the end of pregnancy or early postpartum. No effective, specific treatment for PPCM is available and heart transplantation or mechanical circulatory support may be required in severe cases where drug treatment for heart failure is insufficient. The mechanisms through which the disease progresses are not well understood, and despite similar clinical characteristics to dilated cardiomyopathy of other etiologies (nonperipartum cardiomyopathy; NPCM) it is not known how the molecular remodeling differs between these groups. We aimed to provide insight into the human PPCM heart using …

Developing Curcumin Analogues For Treating Breast Cancer, Tulasi Laxmi Nutalapati

Theses, Dissertations and Capstones

Breast cancer is still one of the most common types of cancer and one of the most common causes of cancer-related deaths in women around the world. Despite significant advances in early detection and treatment strategies, drug resistance, systemic toxicity, and poor outcomes in aggressive subtypes continue to limit the overall effectiveness of cancer therapy. Natural compounds have become promising anticancer agents because they can target many different things and are not very toxic. Curcumin has shown promise as an anticancer drug, but it cannot be used in the clinic because it does not absorb well, breaks down quickly, and …

Atrial Fibrillation Detection From At-Rest Ppg Signals Using An Sdof-Tf Method, Mamun Hasan, Zhili Hao

Mechanical & Aerospace Engineering Faculty Publications

At-rest PPG signals have been explored for detecting atrial fibrillation (AF), yet current signal-processing techniques do not achieve perfect accuracy even under low-motion artifact (MA) conditions. This study evaluates the effectiveness of a single-degree-of-freedom time–frequency (SDOF-TF) method in analyzing at-rest PPG signals for AF detection. The method leverages the influence of MA on the instant parameters of each harmonic, which is identified using an SDOF model in which the tissue–contact–sensor (TCS) stack is treated as an SDOF system. In this model, MA induces baseline drift and time-varying system parameters. The SDOF-TF method enables the quantification and removal of MA and …

Estrogen Deprivation During Primate (Papio Anubis) Pregnancy: Impact On Systemic Microvascular Flow And Cardiovascular Development And Function After Birth In Offspring, Sifa Turan, Jeffery S. Babischkin, Graham W. Aberdeen, Gerald J. Pepe, Eugene D. Albrecht

Department of Biomedical and Translational Sciences Faculty Publications

Background

Suppressing estradiol (E₂) during baboon pregnancy lowers offspring skeletal muscle capillary density, vital for insulin-mediated glucose uptake, and induces insulin resistance. We examined whether E₂ deprivation also impairs microvascular flow and cardiac function.

Methods

Offspring of untreated baboons, letrozole-treated baboons, or letrozole plus E₂ (maternal s.c. injections during the second half of gestation) underwent contrast-enhanced microbubble ultrasonography to quantify microvessel flow and echocardiography to assess cardiac performance.

Results

Letrozole reduced maternal serum E₂ by 95% (p <  0.01). In letrozole offspring, microbubble flux rate (β) fell 55% (p <  0.02), replenishment was 5 s slower (p <  0.03), and microvessel flow declined 40% (p = 0.05); all were restored by added E₂. Indices of systolic (isovolumic contraction), diastolic (isovolumic relaxation), global performance (Tei index), and cardiac output were unchanged.

Conclusion

Prolonged gestational E₂ deprivation programs a reduction in microvascular flow without altering cardiac function; maternal E₂ prevents this, supporting E₂'s role in …

Ovarian carcinoma and malignant melanoma are the first human tumors where immune responses, primarily restricted to autologous tumor cells, were first demonstrated. T-cell lines and clones developed in recombinant interleukin-2 (rIL-2) from tumor-infiltrating lymphocytes (TIL) from these tumors exhibited cytotoxicity and/or cytokine production, primarily restricted to autologous tumor cells. The T-cell receptor (TCR) and the CD3 differentiation antigen on effector T cells and HLA on …

Confessions In Cases Of Child Physical Abuse - A Capnet Study, Margaret R. Russell, Antoinette L. Laskey, Henry T. Puls, Suzanne P. Starling, Joanne N. Wood, Daniel M. Lindberg, Nancy S. Harper, Caitlin R. Mcnamara, Angela N. Bachim, Farah W. Brink, Lori D. Frasier, James D. Anderst, Porcia Vaughn, Kristine A. Campbell

Department of Pediatrics Faculty Publications

Objective

Prior research on confessions of physical abuse (PA) has explored mechanisms of injury. Little is known about conditions supporting a confession of abuse or how confessions may influence case outcomes.

Methods

This cross-sectional study of suspected PA in children age < 10 years at 10 centers participating in CAPNET, a multicenter child PA research network, included children with in-person Child Abuse Pediatrics (CAP) consultations between Feb 2021-Dec 2022 and excluded children without injury. Our focus was a confession of inflicted injury known to the CAP during clinical involvement. We compared child and clinical characteristics, out-of-home (OOH) placements, and arrests between cases with and without confessions. Multivariable models using generalized estimating equations (GEE) produced adjusted predicted probabilities (APP) clustering by CAPNET site.

Results

Confessions were known to CAPs in 115/4297 (2.7%) cases, with significant site variability. In a multivariable GEE model, confessions were more likely in cases with injuries with high-specificity for abuse (APP 6.0% vs 1.5%, p< 0.001), near-fatality (APP 5.5% vs 2.3%, p< 0.001), and older children (APP 4.8% vs 2.5%, p = 0.025). OOH placements and arrests were more common in cases with confessions. CAP awareness of confessions, OOH placements, and arrests did not follow racial or ethnic patterns seen in the US child welfare system. Lower socioeconomic status was associated with OOH placements and arrests but not CAP awareness of confessions.

Conclusions

Our findings highlight differences in case characteristics and outcomes where a confession is known to the CAP and raise questions about agency …

Dementia Incidence In Patients With Prurigo Nodularis: An Observational Retrospective Cohort Study, Madison P. Olexson, Ana Ormaza Vera, Chunghwan Ro, Clinton W. Enos

Department Dermatology Faculty Publications

[Introduction] Prurigo nodularis (PN) is a chronic neuroinflammatory dermatosis of unknown etiology characterized by severely pruritic, symmetrically-distributed nodules with a negative impact on quality of life [1]. While some consider PN a primary idiopathic disorder, it often arises as a secondary manifestation of underlying conditions, including atopic dermatitis (AD), chronic kidney disease (CKD), human-immunodeficiency-virus (HIV), and thyroid disorders [2]. Although patients with PN are at higher risk for psychiatric comorbidities including depression, anxiety, and suicidal ideation [3] research which investigates associations between PN and neurodegenerative disorders is limited [4]. Moreover, emerging evidence implicating sustained systemic inflammation, characteristic of psoriasis and …

Research and Infrastructure Service Enterprise (RISE) Faculty Publications

In the United States, Colorectal Cancer (CRC) is one of the most commonly diagnosed cancers and the third leading cause of death among non-Hispanic African American/Black (henceforth Black) men. Inadequate CRC knowledge leads to missing early warning signs, delaying prevention and increasing risk. Emerging adulthood (18-25) is a key period for building healthy behaviors and addressing barriers to CRC knowledge in addition to understanding attitudes and practices to CRC screening. Psychosocial barriers - including social support, medical mistrust, and perceived racial discrimination - contribute to the lack of CRC knowledge among older Black men, yet emerging adult Black men remain …
