Application Of Intravenous Laser Irradiation Of Blood (Ilib) In Physical Medicine: A Narrative Review, Ya-Chi Chuang, Yuan-Yang Cheng

Rehabilitation Practice and Science

Intravenous laser irradiation of blood (ILIB) involves a type of intravascular treatment which applies a helium-neon laser possessing a wavelength of 632.8nm. Since its first use in 1981 by Russian scientists, it is now widely applied in the treatment of various diseases, including chronic musculoskeletal pain, wound healing, spinal cord injury, stroke, traumatic brain injury, coronary artery disease, type 2 diabetes mellitus, rheumatoid arthritis and acute kidney injury. The underlying mechanism for ILIB may be associated with its anti-oxidative (through regulating the reactive oxygen species systems) and anti-inflammatory effects (by reducing the production of inflammatory cytokines). Moreover, positive effects on …

From Pre-Clinical To Translational Brain Metastasis Research: Current Challenges And Emerging Opportunities, Emilija Aleksandrovic, Siyuan Zhang, Dihua Yu

Faculty, Staff and Student Publications

Brain metastasis, characterized by poor clinical outcomes, is a devastating disease. Despite significant mechanistic and therapeutic advances in recent years, pivotal improvements in clinical interventions have remained elusive. The heterogeneous nature of the primary tumor of origin, complications in drug delivery across the blood-brain barrier, and the distinct microenvironment collectively pose formidable clinical challenges in developing new treatments for patients with brain metastasis. Although current preclinical models have deepened our basic understanding of the disease, much of the existing research on brain metastasis has employed a reductionist approach. This approach, which often relies on either in vitro systems or in …

Genetic Evidence For Functional Diversification Of Gram-Negative Intermembrane Phospholipid Transporters, Ashutosh K Rai, Katsuhiro Sawasato, Haley C Bennett, Anastasiia Kozlova, Genevieve C Sparagna, Mikhail Bogdanov, Angela M Mitchell

Faculty, Staff and Student Publications

The outer membrane of gram-negative bacteria is a barrier to chemical and physical stress. Phospholipid transport between the inner and outer membranes has been an area of intense investigation and, in E. coli K-12, it has recently been shown to be mediated by YhdP, TamB, and YdbH, which are suggested to provide hydrophobic channels for phospholipid diffusion, with YhdP and TamB playing the major roles. However, YhdP and TamB have different phenotypes suggesting distinct functions. It remains unclear whether these functions are related to phospholipid metabolism. We investigated a synthetic cold sensitivity caused by deletion of fadR, a transcriptional regulator …

Faculty, Staff and Student Publications

BACKGROUND: The complex relationship between measured leukocyte telomere length (LTL), genetically predicted LTL (gTL), and carcinogenesis is exemplified by lung cancer. We previously reported associations between longer pre-diagnostic LTL, gTL, and increased lung cancer risk among European and East Asian populations. However, we had limited statistical power to examine the associations among never smokers by gender and histology.

METHODS: To investigate further, we conducted nested case-control analyses on an expanded sample of never smokers from the prospective Shanghai Women's Health Studies (798 cases and 792 controls) and Shanghai Men's Health Studies (161 cases and 162 controls). We broke the case-control …

Advances In The Integration Of Microalgal Communities For Biomonitoring Of Metal Pollution In Aquatic Ecosystems Of Sub-Saharan Africa, Mary Mulenga, Concillia Monde, Todd Johnson, Kennedy O Ouma, Stephen Syampungani

Faculty, Staff and Student Publications

This review elucidated the recent advances in integrating microalgal communities in monitoring metal pollution in aquatic ecosystems of sub-Saharan Africa (SSA). It also highlighted the potential of incorporating microalgae as bioindicators in emerging technologies, identified research gaps, and suggested directions for further research in biomonitoring of metal pollution. Reputable online scholarly databases were used to identify research articles published between January 2000 and June 2023 for synthesis. Results indicated that microalgae were integrated either individually or combined with other bioindicators, mainly macroinvertebrates, macrophytes, and fish, alongside physicochemical monitoring. There was a significantly low level of integration (< 1%) of microalgae for biomonitoring aquatic metal pollution in SSA compared to other geographical regions. Microalgal communities were employed to assess compliance (76%), in diagnosis (38%), and as early-warning systems (38%) of aquatic ecological health status. About 14% of biomonitoring studies integrated microalgal eDNA, while other technologies, such as remote sensing, artificial intelligence, and biosensors, are yet to be significantly incorporated. Nevertheless, there is potential for the aforementioned emerging technologies for monitoring aquatic metal pollution in SSA. Future monitoring in the region should also consider the standardisation and synchronisation of integrative biomonitoring and embrace the "Citizen Science" concept at national and regional scales.

A Prismatic View Of The Epigenetic-Metabolic Regulatory Axis In Breast Cancer Therapy Resistance, Chandrima Das, Apoorva Bhattacharya, Swagata Adhikari, Atanu Mondal, Payel Mondal, Santanu Adhikary, Siddhartha Roy, Kenneth Ramos, Kamlesh K Yadav, John A Tainer, Tej K Pandita

Faculty, Staff and Student Publications

Epigenetic regulation established during development to maintain patterns of transcriptional expression and silencing for metabolism and other fundamental cell processes can be reprogrammed in cancer, providing a molecular mechanism for persistent alterations in phenotype. Metabolic deregulation and reprogramming are thus an emerging hallmark of cancer with opportunities for molecular classification as a critical preliminary step for precision therapeutic intervention. Yet, acquisition of therapy resistance against most conventional treatment regimens coupled with tumor relapse, continue to pose unsolved problems for precision healthcare, as exemplified in breast cancer where existing data informs both cancer genotype and phenotype. Furthermore, epigenetic reprograming of the …

BACKGROUND: Previous evidence supports androgen deprivation therapy (ADT) with primary radiotherapy as initial treatment for intermediate-risk and high-risk localised prostate cancer. However, the use and optimal duration of ADT with postoperative radiotherapy after radical prostatectomy remains uncertain.

METHODS: RADICALS-HD was a randomised controlled trial of ADT duration within the RADICALS protocol. Here, we report on the comparison of short-course versus long-course ADT. Key eligibility criteria were indication for radiotherapy after previous radical prostatectomy for prostate cancer, prostate-specific antigen less than 5 ng/mL, absence of metastatic disease, and written consent. Participants were randomly assigned (1:1) to add 6 months of ADT …

Mash: Mediation Analysis Of Survival Outcome And High-Dimensional Omics Mediators With Application To Complex Diseases, Sunyi Chi, Christopher R Flowers, Ziyi Li, Xuelin Huang, Peng Wei

Faculty, Staff and Student Publications

Environmental exposures such as cigarette smoking influence health outcomes through intermediate molecular phenotypes, such as the methylome, transcriptome, and metabolome. Mediation analysis is a useful tool for investigating the role of potentially high-dimensional intermediate phenotypes in the relationship between environmental exposures and health outcomes. However, little work has been done on mediation analysis when the mediators are high-dimensional and the outcome is a survival endpoint, and none of it has provided a robust measure of total mediation effect. To this end, we propose an estimation procedure for Mediation Analysis of Survival outcome and High-dimensional omics mediators (MASH) based on sure …

Macroautophagy/autophagy is a complex degradation process with a dual role in cell death that is influenced by the cell types that are involved and the stressors they are exposed to. Ferroptosis is an iron-dependent oxidative form of cell death characterized by unrestricted lipid peroxidation in the context of heterogeneous and plastic mechanisms. Recent studies have shed light on the involvement of specific types of autophagy (e.g. ferritinophagy, lipophagy, and clockophagy) in initiating or executing ferroptotic cell death through the selective degradation of anti-injury proteins or organelles. Conversely, other forms of selective autophagy (e.g. reticulophagy and lysophagy) enhance the cellular defense …

Incarceration Vs Treatment: Is One More Effective Than The Other In Preventing Recidivism For Drug Abuse?, Scott G. Kang

Student Theses

This study aims to determine the most effective approach for reducing recidivism among drug offenders, comparing incarceration with treatment. Two hypotheses were formulated for this research: 1) Drug offenders undergoing residential treatment will experience lower recidivism rates compared to those sentenced to incarceration. 2) Extended therapeutic treatment is more likely to positively influence behavior change among drug abusers compared to longer prison sentences. These hypotheses were tested using data from 263 participants in the Drug Treatment Alternative-to-Prison (DTAP) program, analyzed through logistic regression in SPSS. The results indicate that therapeutic interventions, specifically rehabilitative treatment, are more effective than incarceration in …

Public health surveillance and data systems in the US remain an unnamed facet of structural racism. What gets measured, which data get collected and analyzed, and how and by whom are not matters of happenstance. Rather, surveillance and data systems are productions and reproductions of political priority, epistemic privilege, and racialized state power. This has consequences for how communities of color are represented or misrepresented, viewed, and valued and for what is prioritized and viewed as legitimate cause for action. Surveillance and data systems accordingly must be understood as both an instrument of structural racism and an opportunity to dismantle …

Indiana has a business-friendly environment, but historical underinvestment in public health has yielded poor health outcomes. In 2023, when trust in governmental public health was strained nationwide, Indiana increased public health spending by 1,500 percent. In this article, we explain how Indiana achieved this unprecedented legislative victory for public health, describing the context, approach, and lessons learned. Specifically, an Indiana University report linking economic vitality and overall health sparked the creation of a governor's commission charged with exploring ways to address Indiana's shortcomings. Working with the Indiana Department of Health, the commission developed multisectoral coalitions and business and government partnerships, …

Three-Dimensional Imaging Studies In Mice Identify Cellular Dynamics Of Skeletal Muscle Regeneration, Brittany C. Collins, Jacob B. Shapiro, Mya M. Scheib, Robert V. Musci, Mayank Verma, Gabrielle Kardon

Health and Human Sciences Faculty Works

The function of many organs, including skeletal muscle, depends on their three-dimensional structure. Muscle regeneration therefore requires not only reestablishment of myofibers but also restoration of tissue architecture. Resident muscle stem cells (SCs) are essential for regeneration, but how SCs regenerate muscle architecture is largely unknown. We address this problem using genetic labeling of mouse SCs and whole-mount imaging to reconstruct, in three dimensions, muscle regeneration. Unexpectedly, we found that myofibers form via two distinct phases of fusion and the residual basement membrane of necrotic myofibers is critical for promoting fusion and orienting regenerated myofibers. Furthermore, the centralized myonuclei characteristic …

Chronic pain, a complex and debilitating condition, involves intricate interactions between central and peripheral inflammatory processes. Cytokines, specifically tumor necrosis factor (TNF) and interleukins (IL), are key mediators in the initiation and maintenance of chronic pain states. Sensory neurons expressing receptors for cytokines like TNF, IL-1, and IL-6 are implicated in peripheral sensitization, contributing to increased signaling of painful sensations. The potential of targeting TNF and IL for therapeutic intervention in chronic pain states is the focus of this review, with preclinical and clinical evidence supporting the use of TNF and IL modulators for pain management.

Single-Cell Analysis Identifies Plk1 As A Driver Of Immunosuppressive Tumor Microenvironment In Luad, Yifan Kong, Chaohao Li, Jinpeng Liu, Sai Wu

Markey Cancer Center Faculty Publications

PLK1 (Polo-like kinase 1) plays a critical role in the progression of lung adenocarcinoma (LUAD). Recent studies have unveiled that targeting PLK1 improves the efficacy of immuno- therapy, highlighting its important role in the regulation of tumor immunity. Nevertheless, our understanding of the intricate interplay between PLK1 and the tumor microenvironment (TME) remains incomplete. Here, using genetically engineered mouse model and single- cell RNA-seq analysis, we report that PLK1 promotes an immunosuppressive TME in LUAD, characterized with enhanced M2 polarization of tumor associated macrophages (TAM) and dampened antigen presentation process. Mechanistically, elevated PLK1 coin- cides with increased secretion of CXCL2 …

Markey Cancer Center Faculty Publications

Androgen has long been recognized for its pivotal role in the sexual dimorphism of cardiovascular diseases, including aortic aneurysms (AAs), a devastating vascular disease with a higher prevalence and fatality rate in men than in women. However, the mechanism by which androgen mediates AAs is largely unknown. Here, we found that male, not female, mice developed AAs when exposed to aldosterone and high salt (Aldo-salt). We revealed that androgen and androgen receptors (ARs) were crucial for this sexually dimorphic response to Aldo-salt. We identified programmed cell death protein 1 (PD-1), an immune checkpoint, as a key link between androgen and …
