Toward A Politics Of Care: Southeast Asian Refugee Organizing, Kinship, Care, And Reunion, James Huỳnh, Victoria Huỳnh, Mads Lê, Sheila Sy

Faculty, Staff and Student Publications

From a critical refugee studies orientation, our article redefines care within the context of myriad forms of state violence impacting Southeast Asian post-war refugee communities. Research reveals how harm is compounded at every step of Southeast Asian refugee journeys: war, forced displacement, resettlement, family separation, inherited health conditions, and generational trauma. How do we reckon with refugee trauma without conceding to it as an unchangeable fact of our lives? What knowledge might we gain by attending to the everyday work of survival in refugee communities? To answer these questions, the authors conceptualize care through (a) abolitionist organizing, (b) queer kinship …

Engineering Small-Molecule And Protein Drugs For Targeting Bone Tumors, Yixian Wang, Chenhang Wang, Meng Xia, Zeru Tian, Joseph Zhou, Julian Meyer Berger, Xiang H-F Zhang, Han Xiao

Faculty, Staff and Students Publications

Bone cancer is common and severe. Both primary (e.g., osteosarcoma, Ewing sarcoma) and secondary (e.g., metastatic) bone cancers lead to significant health problems and death. Currently, treatments such as chemotherapy, hormone therapy, and radiation therapy are used to treat bone cancer, but they often only shrink or slow tumor growth and do not eliminate cancer completely. The bone microenvironment contributes unique signals that influence cancer growth, immunogenicity, and metastasis. Traditional cancer therapies have limited effectiveness due to off-target effects and poor distribution on bones. As a result, therapies with improved specificity and efficacy for treating bone tumors are highly needed. …

Faculty, Staff and Students Publications

Bacterial nanocellulose (BNC) is a promising dietary fiber with potential as a functional food additive. We evaluated BNC fibers (BNCf) in the Caenorhabditis elegans model to obtain insight into the BNCf's biointeraction with its gastrointestinal tract while reducing the variables of higher complex animals. BNCf were uptaken and excreted by worms without crossing the intestinal barrier, confirming its biosafety regarding survival rate, reproduction, and aging for concentrations up to 34 μg/ml BNCf. However, a slight decrease in the worms' length was detected. A possible nutrient shortage or stress produced by BNCf was discarded by measuring stress and chemotactic response pathways. …

Mechanisms Driving Fasting-Induced Protection From Genotoxic Injury In The Small Intestine, Kali Deans-Fielder, Timothy Wu, Thanh Nguyen, Sarah To, Yang-Zhe Huang, Steven J Bark, Jason C Mills, Noah F Shroyer

Faculty, Staff and Students Publications

Genotoxic agents such as doxorubicin (DXR) can cause damage to the intestines that can be ameliorated by fasting. How fasting is protective and the optimal timing of fasting and refeeding remain unclear. Here, our analysis of fasting/refeeding-induced global intestinal transcriptional changes revealed metabolic shifts and implicated the cellular energetic hub mechanistic target of rapamycin complex 1 (mTORC1) in protecting from DXR-induced DNA damage. Our analysis of specific transcripts and proteins in intestinal tissue and tissue extracts showed that fasting followed by refeeding at the time of DXR administration reduced damage and caused a spike in mTORC1 activity. However, continued fasting …

The Role Of Psychogenic Factors In The Etiopathogenesis Of Autoimmune Disorders In The Oral Cavity, Nadya T. Avramova, Boyko K. Bonev

Journal of Mind and Medical Sciences

Autoimmune disorders (AD) represent a heterogeneous group of multifactorial chronic conditions, which are triggered secondary to the loss of self-antigen tolerance. Their etiology involves genetic, epigenetic, and environmental factors; however, AD cannot be explained by these factors alone. Recent studies have shown increasing stress levels in industrialized countries and also increasing trends in the prevalence of autoimmune diseases. The oral mucosa is extremely responsive to emotional influences such as stress, anxiety and depression. Therefore, oral diseases can appear as a direct expression of emotions or indirectly, due to various psychological mechanisms. The aim of this study is to find and …

Modeling The Transmission Dynamics Of Tuberculosis In Humans, Farida Kisinda, Joshua A. Mwasunda, Mbwiga S. Aloni

Tanzania Journal of Science

Tuberculosis (TB) is a major threat to human health particularly in most of developing countries. In this article, we formulate and analyze a deterministic model for the transmission dynamics of pulmonary and extra-pulmonary tuberculosis. The next generation method is employed to find the basic reproduction number which helps to determine whether TB clears or persists in the human population. Global stability of model equilibria is done through Lyapunov functions whereas the normalized forward sensitivity index method is adopted to determine parameters that drive tuberculosis. Analysis shows that both TB free and endemic equilibria exist. The TB free equilibrium is globally …

Internalization from the cell membrane and endosomal trafficking of receptor tyrosine kinases (RTKs) are important regulators of signaling in normal cells that can frequently be disrupted in cancer. The adrenal tumor pheochromocytoma (PCC) can be caused by activating mutations of the rearranged during transfection (RET) receptor tyrosine kinase, or inactivation of TMEM127, a transmembrane tumor suppressor implicated in trafficking of endosomal cargos. However, the role of aberrant receptor trafficking in PCC is not well understood. Here, we show that loss of TMEM127 causes wildtype RET protein accumulation on the cell surface, where increased receptor density facilitates constitutive ligand-independent activity and …

Reproductive Justice In Mississippi: A Call For Reform And Acknowledgement, Andie Udziela

Honors Theses

In this thesis, I apply the values of the Reproductive Justice Movement to reproductive healthcare resources in Mississippi to advocate for reproductive policy reform. I begin by navigating the historic racial discrimination in gynecology and how it manifested in Mississippi. Dr Sim’s abusive experimentation on Anarcha, Betsy, and Lucy depict how Anti-Black racism took root in gynecology and obstetrics and was later expanded on by the eugenic goals of white supremacy and the feminist movement through Margaret Sanger and the Mississippi Appendectomy. Then I discuss the current availability of reproductive care in Mississippi to low-income individuals to emphasize socioeconomic and …

Exploring The Experience Of Healthcare-Related Epistemic Injustice Among People With Myalgic Encephalomyelitis / Chronic Fatigue Syndrome, Joanne Hunt, Jessica Runacres, Daniel Herron, David Sheffield

The Qualitative Report

Myalgic encephalomyelitis / chronic fatigue syndrome (ME/CFS) is a chronic, disabling yet clinically “contested” condition, previously theorised through a lens of epistemic injustice. Phenomena conceptually close to epistemic injustice, including stigma, are known to have deleterious consequences on a person’s health and life-world. Yet, no known primary studies have explored how people with ME/CFS experience healthcare through a lens of epistemic injustice, whilst a dearth of research explicitly exploring healthcare-related injustice from a patient perspective has been noted. This qualitative study seeks to address this gap. Semi-structured interviews and interpretative phenomenological analysis (IPA) were used to explore the experiences of …

The rapid evolution of SARS-CoV-2 is driven in part by a need to evade the antibody response in the face of high levels of immunity. Here, we isolate spike (S) binding monoclonal antibodies (mAbs) from vaccinees who suffered vaccine break-through infections with Omicron sub lineages BA.4 or BA.5. Twenty eight potent antibodies are isolated and characterised functionally, and in some cases structurally. Since the emergence of BA.4/5, SARS-CoV-2 has continued to accrue mutations in the S protein, to understand this we characterize neutralization of a large panel of variants and demonstrate a steady attrition of neutralization by the panel of …
