E-Cigarettes Theory To Alternative To Smoking And Associated Emerging Health Concerns, Utsav Pokharel

Master's Projects and Capstones

E-cigarettes have emerged as a popular alternative to traditional smoking, with proponents advocating for their potential role in smoking cessation. However, the health implications of e-cigarettes remain a contentious issue within public health discourse. This paper conducts a comprehensive review of the current literature to evaluate the efficacy of e-cigarettes as a smoking cessation tool and to assess their associated health risks. The study finds that while e-cigarettes may produce fewer toxicants than combustible cigarettes, their long-term health effects are still largely unknown. Evidence suggests that e-cigarette use can lead to adverse health outcomes, including lung and cardiovascular diseases, driven …

“Wa Ya See?”: An Autoethnographic Exploration Of The Nuanced Experiences Of A Black, Quare, Afro-Caribbean, Asylum Seeker In The United States Higher Education., Travis A. Richards

LMU Theses and Dissertations

In the 2022-2023 academic year, nearly one million international students from over 200 countries enrolled in U.S. higher education institutions, marking a 12% increase from the previous year (Martel & Baer, 2022). Despite representing 5.6% of the total U.S. higher education population, asylum-seeking students remained an overlooked demographic, underscoring the challenges faced by marginalized groups within academia (Buchholz, 2023). This research focused on the experience of a Black, Quare, Afro-Caribbean, asylum-seeking doctoral student, employing autoethnographic methods to examine the complex intersections of race, sexuality, and transnational identity. Grounded in Intersectionality Theory (Crenshaw, 1991), Critical Race Theory (Bell, 1995), Quare Theory …

Advancing Methods For Studying The Neuroscience Of Sex Variability And Diversity, Vic Shao-Chih Chiang

Graduate Doctoral Dissertations

Sex variability and diversity are pervasive across taxa and genera. Society is heavily structured around sex/gender conceptualizations, and neuroscience research actively shapes these constructs. This dissertation adopts frameworks that challenge ideologies perpetuating sex/gender injustices and developed neuroscience-related methodologies that could advance the conceptualisations of sex. First, I studied B6D2F1 mice which exhibit sexual behaviour months after castration. This challenged the dogma that sexual behaviour is dependent on gonadal steroid hormones. I enhanced the behavioural analysis of these mice using deep learning techniques. Second, applying similar deep learning methods, I refined the behavioural analysis of Astatotilapia burtoni cichlids, which exhibit sexual …

Synthesise Of Iron Oxide Nanoparticles Ionps By Laser Method As An Antibacterial And Hemocompatibility Agent, Asraa Radhi, Khawla Khashan, Ghassan Sulaiman, Hamdoon Mohammed

Journal of Applied Sciences and Nanotechnology

In this work, room temperature laser ablation with an iron target in water was used to create iron oxide nanoparticles (IONPs) with a different number of pulses (100, 200, 300, 400 and 500) at a constant energy of 200 mJ. The colloidal solutions of the IONPs were studied and the effects of the number of pulses on the properties were investigated by Fourier transform infrared spectroscopy (FTIR), field emission scanning electron microscopy (FESEM), ultraviolet-visible spectroscopy (UV-VIS) and photoluminescence (PL). The FTIR spectra showed that the synthesised IONPs were formed, and the peaks appeared between (500-600) cm-1. FESEM images showed that …

Pathology, East Africa

The growing resistance to amoxicillin (AMX)—one of the main antibiotics used in Helicobacter pylori eradication therapy—is an increasing health concern. Several mutations of penicillin-binding protein 1A (PBP1A) are suspected of causing AMX resistance; however, only a limited set of these mutations have been experimentally explored. This study aimed to investigate four PBP1A mutations (i.e., T558S, N562H, T593A, and G595S) carried by strain KIN76, a high-level AMX-resistant clinical H. pylori isolate with an AMX minimal inhibition concentration (MIC) of 2 µg/mL. We transformed a recipient strain 26695 with the DNA containing one to four mutation allele combinations of the pbp1 gene …

Accurate assessment of GFR is crucial to guiding drug eligibility, dosing of systemic therapy, and minimizing the risks of both undertreatment and toxicity in patients with cancer. Up to 32% of patients with cancer have baseline CKD, and both malignancy and treatment may cause kidney injury and subsequent CKD. To date, there has been lack of guidance to standardize approaches to GFR estimation in the cancer population. In this two-part statement from the American Society of Onco-Nephrology, we present key messages for estimation of GFR in patients with cancer, including the choice of GFR estimating equation, use of race and …

Electrical Stimulation Of The Dorsal Motor Nucleus Of The Vagus In Male Mice Can Regulate Inflammation Without Affecting The Heart Rate, Aidan Falvey, Santhoshi P Palandira, Sangeeta S Chavan, Michael Brines, Robert Dantzer, Kevin J Tracey, Valentin A Pavlov

Faculty, Staff and Student Publications

Background: The vagus nerve plays an important role in neuroimmune interactions and in the regulation of inflammation. A major source of efferent vagus nerve fibers that contribute to the regulation of inflammation is the brainstem dorsal motor nucleus of the vagus (DMN), as recently shown using optogenetics. In contrast to optogenetics, electrical neuromodulation has broad therapeutic implications. However, the anti-inflammatory effectiveness of electrical stimulation of the DMN (eDMNS) and the possible heart rate (HR) alterations associated with this approach have not been investigated. Here, we examined the effects of eDMNS on HR and cytokine levels in mice administered with lipopolysaccharide …

Collaborative Filtering For The Imputation Of Patient Reported Outcomes, Eric Ababio Anyimadu, Clifton David Fuller, Xinhua Zhang, G Elisabeta Marai, Guadalupe Canahuate

Faculty, Staff and Student Publications

This study addresses the prevalent issue of missing data in patient-reported outcome datasets, particularly focusing on head and neck cancer patient symptom ratings sourced from the MD Anderson Symptom Inventory. Given that many data mining and machine learning algorithms necessitate complete datasets, the accurate imputation of missing data as an initial step becomes crucial. In this study we propose, for the first time, the use of collaborative filtering for imputing missing head and neck cancer patient symptom ratings. Two configurations of collaborative filtering, namely patient-based and symptom-based, leverage known ratings to infer the missing ones. Additionally, this study compares the …

Association Between Intravenous Fluids During Labor And Primary Postpartum Hemorrhage: A Retrospective Cohort Study, Belinda R Bruce, Heather L Shepherd, Saleem Ahmed Khan, Charlotte R Haunton, Julie Leask, Bradley S De Vries

Faculty, Staff and Student Publications

INTRODUCTION: There is a major research gap relating to the impact of intravenous (IV) fluids administration during labor on maternal and neonatal outcomes. It is biologically plausible that a relationship between volume of IV fluids and primary postpartum hemorrhage (PPH) exists. The primary objective of this study was to evaluate whether the administration of high-volume IV fluids during labor (≥ 2500 mL) increases the risk of primary PPH and other adverse outcomes for women with a term, singleton pregnancy, in comparison to low-volume IV fluids during labor (<2500 >mL).

MATERIAL AND METHODS: A retrospective cohort study was conducted at a …

Targeting Adenosine A2b Receptor Promotes Penile Rehabilitation Of Refractory Erectile Dysfunction, Yang Xiong, Feng Qin, Shanzun Wei, Xingliang Yang, Jun Li, Changjing Wu, Fuxun Zhang, Jiuhong Yuan

Faculty, Staff and Student Publications

The mechanisms of adenosine and specific adenosine receptor subtypes in promoting penile rehabilitation remain unclear. Single‐cell RNA sequencing of human corpus cavernosum,  adenosine deaminase (ADA) and adenosine receptors knock‐out mice (ADA−/−, A1−/−, A2a−/−, A2b−/−, and A3−/−), and primary corpus cavernosum smooth muscle cells are used to determine receptor subtypes responsible for adenosine‐induced erection. Three rat models are established to characterize refractory erectile dysfunction (ED): age‐related ED, bilateral cavernous nerve crush related ED (BCNC), and diabetes mellitus‐induced ED. In single‐cell RNA sequencing data, the corpus cavernosum of ED patients show a decrease in adenosine A1, A2a and A2b receptors. In vivo, …

Vertebrate And Invertebrate Animal Infection Models Of Candida Auris Pathogenicity, Melissa Martinez, Danielle A Garsin, Michael C Lorenz

Faculty, Staff and Student Publications

Candida auris is an emerging fungal pathogen with several concerning qualities. First recognized in 2009, it has arisen in multiple geographically distinct genomic clades nearly simultaneously. C. auris strains are typically multidrug resistant and colonize the skin much better than most other pathogenic fungi; it also persists on abiotic surfaces, enabling outbreaks due to transmission in health care facilities. All these suggest a biology substantially different from the 'model' fungal pathogen, Candida albicans and support intensive investigation of C. auris biology directly. To uncover novel virulence mechanisms in this species requires the development of appropriate animal infection models. Various studies …

Structure And Function Are Not The Same: The Case For Restoring Mechanoreceptor Continuity Following Anterior Cruciate Ligament Injury, Jillian E Beveridge, Payam Zandiyeh, Brett D Owens, Ata M Kiapour, Braden C Fleming

Faculty, Staff and Student Publications

Anterior cruciate ligament (ACL) injury, particularly in increasingly young and active adolescents, continues to pose a clinical challenge with re-injury rates reported as high as 30%. Evidence also suggests that current standard-of-care ACL reconstruction (ACLR) does not mitigate post-traumatic osteoarthritis (PTOA) risk. Bridge- enhanced ACL restoration (BEAR) is a recently developed and tested ACL surgery that promotes primary healing of the native ACL with excellent early results. BEAR has shown to reduce signs of early PTOA compared to ACLR in an animal model. Here, we describe a theoretical framework related to re-innervation that can clarify why the outcomes of ACLR …

4d Dynamic Spatial Brain Networks At Rest Linked To Cognition Show Atypical Variability And Coupling In Schizophrenia, Krishna Pusuluri, Zening Fu, Robyn Miller, Godfrey Pearlson, Peter Kochunov, Theo G M Van Erp, Armin Iraji, Vince D Calhoun

Faculty, Staff and Student Publications

Despite increasing interest in the dynamics of functional brain networks, most studies focus on the changing relationships over time between spatially static networks or regions. Here we propose an approach to study dynamic spatial brain networks in human resting state functional magnetic resonance imaging (rsfMRI) data and evaluate the temporal changes in the volumes of these 4D networks. Our results show significant volumetric coupling (i.e., synchronized shrinkage and growth) between networks during the scan, that we refer to as dynamic spatial network connectivity (dSNC). We find that several features of such dynamic spatial brain networks are associated with cognition, with …

Candida Albicans Natural Diversity: A Resource To Dissect Fungal Commensalism And Pathogenesis, Elena Lindemann-Perez, J Christian Perez

Faculty, Staff and Student Publications

Candida albicans is a ubiquitous fungus of humans. It is not only a component of the oral and intestinal microbiota of most healthy adults but also a major cause of mucosal disorders and life-threatening disseminated infections. Until recently, research on the biology and pathogenesis of the fungus was largely based on a single clinical isolate. We review investigations that have started to dissect a diverse set of C. albicans strains. Using different approaches to leverage the species' phenotypic and/or genetic diversity, these studies illuminate the wide range of interactions between fungus and host. While connecting genetic variants to phenotypes of …

Patient-derived organoids (PDOs) developed ex vivo and in vitro are increasingly used for therapeutic screening. They provide a more physiologically relevant model for drug discovery and development compared to traditional cell lines. However, several challenges remain to be addressed to fully realize the potential of PDOs in therapeutic screening. This paper summarizes recent advancements in PDO development and the enhancement of PDO culture models. This is achieved by leveraging materials engineering and microfabrication technologies, including organs-on-a-chip and droplet microfluidics. Additionally, this work discusses the application of PDOs in therapy screening to meet diverse requirements and overcome bottlenecks in cancer treatment. …

Trauma-Related Cognitions And Discrimination As Predictors Of Maladaptive Coping Among Marginalized Maltreated Youth, Shadie Burke

UNLV Theses, Dissertations, Professional Papers, and Capstones

Maltreated youth are at an increased risk for engaging in direct or indirect self-injurious behavior to cope with the aftereffects of a traumatic event. These behaviors are often associated with negative health outcomes, substance use and premature death. Existing research proposes a link between child maltreatment and indirect self-harm but the mechanism into why this occurs is unclear. The present study examined two key research questions: (1) which specific trauma-related cognitions, sexual identity and cultural factors predict direct self-injurious behavior (previous suicide attempt(s) and NSSI) among marginalized maltreated youth?; and (2) which specific trauma-related cognitions, sexual identity and cultural factors …

Manuscripts, Articles, Book Chapters and Other Papers

It is not clear as to whether weight bearing and ambulation may affect bone growth. Our goal was to study the role of mechanical loading (one of the components of ambulation) on endochondral ossification and longitudinal bone growth. Thus, we applied cyclical, biologically relevant strains for a prolonged time period (4 weeks) to one tibia of juvenile mice, while using the contralateral one as an internal control. By the end of the 4-week loading period, the mean tibial growth of the loaded tibiae was significantly greater than that of the unloaded tibiae. The mean height and the mean area of …

Why Do Patients With Cancer Die?, Adrienne Boire, Katy Burke, Thomas R Cox, Theresa Guise, Mariam Jamal-Hanjani, Tobias Janowitz, Rosandra Kaplan, Rebecca Lee, Charles Swanton, Matthew G Vander Heiden, Erik Sahai

Faculty, Staff and Student Publications

Cancer is a major cause of global mortality, both in affluent countries and increasingly in developing nations. Many patients with cancer experience reduced life expectancy and have metastatic disease at the time of death. However, the more precise causes of mortality and patient deterioration before death remain poorly understood. This scarcity of information, particularly the lack of mechanistic insights, presents a challenge for the development of novel treatment strategies to improve the quality of, and potentially extend, life for patients with late-stage cancer. In addition, earlier deployment of existing strategies to prolong quality of life is highly desirable. In this …

Faculty, Staff and Student Publications

Successful treatment of glioblastoma multiforme (GBM), an aggressive form of primary brain neoplasm, mandates the need to develop new therapeutic strategies. In this study, we investigated the potential of PBI-05204 in targeting GBM stem cells (GSCs) and the underlying mechanisms. Treatment with PBI-05204 significantly reduced both the number and size of tumor spheres derived from patient-derived GSCs (GBM9, GSC28 and TS543), and suppressed the tumorigenesis of GBM9 xenografts. Moreover, PBI-05204 treatment led to a significant decrease in the expression of CD44 and NANOG, crucial markers of progenitor stem cells, in GBM9 and GSC28 GSCs. This treatment also down-regulated GRP78 expression …
