Review articles can be extremely valuable. They synthesize information for readers, often provide clarity and valuable insights into a topic; and good review articles tend to be cited frequently. Review articles do not require Institutional Review Board (IRB) approval if the data reviewed are public (including private and government databases) and if the articles reviewed have received IRB approval previously. However, some institutions require IRB review and exemption for review articles. So, authors should be familiar with their institution's policy. In assessing and interpreting review articles, it is important to understand the article's methodology, scholarly purpose and credibility. Many readers, …

Involvement Of Tgfβ Signaling Pathway In Oxidative Stress And Diabetic Retinopathy, Reanna Rodriguez, Kristine L. Lowe, Megan Keniry, Andrew Tsin

School of Medicine Publications

Diabetic Retinopathy (DR) is a leading cause of blindness in the U.S. However, not much is known of underlying molecular mechanism and how oxidative stress contributes to its development. In the present study, we investigated the involvement of TGFβ signaling pathway on the effect of oxidative stress on VEGF secretion and viability of retinal cells. VEGF is the hallmark that exacerbates DR progression in prolonged diabetes. Some major concerns that have arisen are the underlying effects of antioxidants in elevating VEGF secretion in diabetes. In this study, we evaluated how hypoxia (or low oxygen) impacts viability and VEGF secretion using …

Multiple studies have established that hyperinflammatory response induced by SARS CoV-2 is a main cause of complications and death in infected subjects. Such dysfunctional immune response has been described as a dysregulated and exacerbated production of cytokines and chemokines that attracts and activates inflammatory cells, which start and sustain pulmonary and systemic damage, thus causing complications that lead to multi organ failure and death. Therefore, we suggest that blocking key inflammation receptors could help to reduce migration and activation of T cells, monocytes/macrophages and neutrophils, thus mitigating the cytokine dysregulation and averting severe complications and death. Importantly, the optimum treatment …

Is Burnout A Depressive Condition? A 14-Sample Meta-Analytic And Bifactor Analytic Study, Renzo Bianchi, Jay Verkuilen, Irvin S. Schonfeld, Jari J. Hakanen, Markus Jansson-Fröjmark, Guadalupe Manzano-García, Eric Laurent, Laurenz L. Meier

Publications and Research

There is no consensus on whether burnout constitutes a depressive condition or an original entity requiring specific medical and legal recognition. In this study, we examined burnout–depression overlap using 14 samples of individuals from various countries and occupational domains (N = 12,417). Meta-analytically pooled disattenuated correlations indicated (a) that exhaustion—burnout’s core—is more closely associated with depressive symptoms than with the other putative dimensions of burnout (detachment and efficacy) and (b) that the exhaustion–depression association is problematically strong from a discriminant validity standpoint (r = .80). The overlap of burnout’s core dimension with depression was further illuminated in 14 exploratory structural …

The Association Of Pregnancy Control, Emotions, And Beliefs With Pregnancy Desires, Meredith G. Manze, Diana R. Romero, Prabal De, Josette Hartnett, Lynn Roberts

Publications and Research

Context

Standard pregnancy intentions measures do not always align with how people approach pregnancy. Studies that have investigated beyond a binary framework found that those with “ambivalent” feelings towards pregnancy are less likely to use contraception consistently, but the reasons for this are unclear. We sought to gain a nuanced understanding of pregnancy desires, and how perceptions about pregnancy are associated with contraceptive use.

Methods

We used non-probability quota sampling based on sex, age, and geographic region for a web-based survey of heterosexual men and women, aged 21–44 years, who could become pregnant/impregnate and were not currently pregnant (n = …

Extracellular Vesicles Released By Human Retinal Pigment Epithelium Mediate Increased Polarised Secretion Of Drusen Proteins In Response To Amd Stressors, Miguel Flores-Bellver, Jason Mighty, Silvia Aparicio-Domingo, Kang V. Li, Cui Shi, Jing Zhou, Hannah Cobb, Patrick Mcgrath, German Michelis, Patricia Lenhart, Ganna Bilousova, Søren Heissel, Michael J. Rudy, Christina Coughlan, Andrew E. Goodspeed, S. Patricia Becerra, Stephen Redenti, M. Valeria Canto-Soler

Age-related macular degeneration (AMD) is a leading cause of blindness worldwide. Drusen are key contributors to the etiology of AMD and the ability to modulate drusen biogenesis could lead to therapeutic strategies to slow or halt AMD progression. The mechanisms underlying drusen biogenesis, however, remain mostly unknown. Here we demonstrate that under homeostatic conditions extracellular vesicles (EVs) secreted by retinal pigment epithelium (RPE) cells are enriched in proteins associated with mechanisms involved in AMD pathophysiology, including oxidative stress, immune response, inflammation, complement system and drusen composition. Furthermore, we provide first evidence that drusen-associated proteins are released as cargo of extracellular …

Human Retinal Organoids Release Extracellular Vesicles That Regulate Gene Expression In Target Human Retinal Progenitor Cells, Jing Zhou, Miguel Flores‑Bellver, Jianbo Pan, Alberto Benito‑Martin, Cui Shi, Onyekwere Onwumere, Jason Mighty, Jiang Qian, Xiufeng Zhong, Tasmim Hogue, Baffour Amponsah‑Antwi, Linda Einbond, Rajendra Gharbaran, Hao Wu, Bo‑Juen Chen, Zhiliang Zheng, Tatyana Tchaikovskaya, Xusheng Zhang, Hector Peinado, Maria Valeria Canto‑Soler, Stephen Redenti

The mechanisms underlying retinal development have not been completely elucidated. Extracellular vesicles (EVs) are novel essential mediators of cell‑to‑cell communication with emerging roles in developmental processes. Nevertheless, the identification of EVs in human retinal tissue, characterization of their cargo, and analysis of their potential role in retina development has not been accomplished. Three‑dimensional retinal tissue derived from human induced pluripotent stem cells (hiPSC) provide an ideal developmental system to achieve this goal. Here we report that hiPSC‑derived retinal organoids release exosomes and microvesicles with small noncoding RNA cargo. EV miRNA cargo‑predicted targetome correlates with Gene Ontology (GO) pathways involved in …

Hip Moment And Knee Power Eccentric Utilisation Ratios Determine Lower-Extremity Stretch-Shortening Cycle Performance, Kristof Kipp, John Krzyszkowski, Jordi Heeneman

Exercise Science Faculty Research and Publications

The eccentric utilisation ratio (EUR) is calculated as the ratio between countermovement jump (CMJ) and squat jump (SJ) heights, and is an indicator of lower-extremity stretch-shortening cycle (SSC) performance in athletes. Joint-based EUR can also be calculated but have never been reported. The purpose of this study was to investigate whether jump height-based (JH-based) EUR can be predicted by joint-specific EUR. Nine NCAA Division I college athletes (age: 21 ± 1 year, height: 1.75 ± 0.15 m, mass: 71 ± 20 kg) performed three SJ and CMJ. During all jumps, kinematic and kinetic data were obtained and used to calculate …

A Lesson Involving Nursing Management Of Diabetes Care: Incorporating Simulation In Didactic Instruction To Prepare Students For Entry-Level Practice, Elizabeth A. Moxley, Larry Maturin Jr., Desale Habtzghi

Faculty Articles, Papers, and Other Scholarship

Background: Diabetes is a global health problem requiring nursing students demonstrate a thorough understanding for NCLEX^® and entry-level practice, although clinical opportunities are increasingly limited, especially for Associate Degree Programs.

Method: A Simulation-based Education was incorporated in a didactic lesson to improve diabetes nursing care. Knowledge, confidence, application and relevance were measured using Wilcoxon signed-rank, Chi-square and Kruskal-Wallis analyses.

Results: Student (n=46, 85% female) perceived knowledge of glycemic management (post > pre, p < 0.0001), confidence administering insulin (post > pre, p < 0.0001), and clinical relevance improved. Confidence increased among three cohorts per Kruskal Wallis H test (² = 7.76, p = 0.021). Increased confidence correlated with relevance (² = 30.965, p = 0.009) and prior understanding of therapy ( …

The Harm In Seeking Care: Assessing The Relationship Between Healthcare Discrimination And Healthcare Avoidance Behaviors In The Past Year And Since The Start Of The Coronavirus Pandemic In A Transgender And Gender Independent Sample, Kyle L. Mason

Theses and Dissertations

Background: Gender minorities encounter a myriad of barriers to accessing general and gender affirming healthcare. Financial disparities impacting affordability of healthcare costs and insurance-based denials for gender-affirming care are among prominent barriers discussed. Considerations of the prevalence of stigma, discrimination, and erasure of gender minority identities must not be neglected when seeking to understand healthcare accessibility and utilization in this population. Previous researchers have examined gender minority patients’ experiences of discrimination in healthcare settings and delaying care due to fear of discrimination. There is a dearth of knowledge about the relationship between lifetime exposure to varied forms of healthcare discrimination …

A Mixed Methods Approach To Examine Racial Disparities In Adherence To Surveillance Mammography Among Breast Cancer Survivors, Megan C. Edmonds

Theses and Dissertations

PURPOSE: Annual surveillance mammography is a critical part of routine cancer care for breast cancer (BC) survivors; reducing mortality by 39%. However, disparities exist with regard to adherence to surveillance mammograms among BC survivors; Black women are 44% less likely to adhere than their White counterparts. Despite the existence of this racial disparity for over a decade, little is known about factors that explain reasons for Black BC survivors’ non-adherence. This is because most studies have not evaluated the role of healthcare delivery or psychosocial factors. Guided by the Behavioral Model for Vulnerable Populations, the purpose of this mixed methods …

The Therapeutic Potential Of Glycosaminoglycan Directed Metalloglycomics: Elucidating New Targets And Mechanisms For Polynuclear Platinum Complexes, James D. Hampton

Theses and Dissertations

Cancer remains a serious clinical problem and in order to continue to improve patient health outcomes, novel treatment strategies must continue to be developed. Platinum chemotherapies remain as one of the most widely successful classes of cancer therapeutic, with over 50% of cancer patients receiving a platinate at some point over the span of their treatment. However, intrinsic and extrinsic resistances limit their effectiveness, long term efficacy, and broad applicability to multiple cancer subtypes. Therefore, the development of new agents and strategies which can overcome these limitations are crucial for patient health. To this end a novel class of polynuclear …

Single-Molecule Investigation Of I-Motif Folding And Dynamics In Bioinspired Dna Platforms, Anoja Megalathan

Theses and Dissertations

Although the canonical right-handed B-DNA is the predominant form of DNA in cells, DNA can adopt other secondary structures such as hairpins, G-quadruplexes (G4), and intercalated motifs (i-motif). These secondary structures are typically formed in the regions with repeat sequences. Among many secondary structures DNA can adopt, G-quadruplexes and i-motifs (tetraplex structures formed in the G-rich and C-rich sequences, respectively) caught significant research interest in recent years due to the prevalence of G-rich and C-rich sequences in the human genome. While G-quadruplexes are extensively studied, little is known about i-motifs – especially their formation and stability under cellular environments. For …

Preclinical Pharmacokinetic Studies Of Pterostilbene, And Its Human Pharmacokinetic Prediction Using Physiologically Based Pharmacokinetic Modeling, Palak S. Phansalkar

Theses and Dissertations

This dissertation research aimed to determine the preclinical pharmacokinetics of pterostilbene in vitro and develop a physiologically based pharmacokinetic (PBPK) model to simulate the animal and human PK profiles for pterostilbene. The in vitro PK characteristics of pterostilbene, including Caco-2 cell permeability, plasma protein binding, and metabolic stability were determined using rat and human intestinal & hepatic S9 subcellular fractions. The in vitro metabolic parameters determined in rat subcellular fractions were extrapolated to in vivo values to predict the oral bioavailability (F_oral) in rats. The predicted F_oral was found to be 43.0 %, which is similar to …

Structural Reorganization Of The Cisternal Organelle In Neuroinflammatory Disease, Myshak S. Abdi

Theses and Dissertations

The axon initial segment (AIS), an axonal sub compartment located immediately distal to the soma, is an important structure in mediating action potential generation and modulation. The morphology of this domain can be altered by a wide variety of activity-dependent, environmental, and pathological triggers. Dysregulation of axonal calcium (Ca²⁺) concentrations, and subsequent enzymatic degradation of AIS cytoskeletal architecture have been reported to underlie structural modifications of the AIS. Moreover, pharmacological inhibition of neuronal Ca²⁺ channels have been shown to mitigate the disruptive effects of neuroinflammation on AIS structural integrity. Here we investigate the Cisternal Organelle (CO), a …

Conformational Modulation Of Α-Helical N-Acetylated Α-Synuclein, Ricardo Fernandez

Theses and Dissertations

Human N-acetylated α-synuclein (^NAcαSyn) has long been accepted as an intrinsically disordered protein (IDP) predominantly found in terminal nerve regions in healthy subjects. ^NAcαSyn structural fluidity enables the formation of transient or dynamic assemblies. Some of these assemblies may serve functional, yet undefined purposes. ^NAcαSyn is highly susceptible to the surrounding environment, leading to misfolding under high cytosolic oxidative stress conditions, which in turn assemble in the form of toxic oligomers or amyloid fibrils. These ^NAcαSyn inclusions along with their accretion and migration within neurons, are pathological hallmarks of Parkinson’s disease (PD), dementia, and multiple …
