Herpes Simplex Keratitis After Prk, Joshua Graf Od

Optometric Clinical Practice

Background: Herpes simplex virus (HSV) is a double stranded DNA virus that infects much of the world’s population. The World Health Organization estimates 67% of people under the age of 50 have HSV-1 and 11% of people under the age of 50 have HSV-2. While most systemic infections remain inactive and do not cause symptoms, the activation and appearance of ocular HSV can be a destructive and vision-threatening issue. HSV keratitis can be epithelial, stromal or a combination. Patients who have recently undergone photorefractive keratectomy (PRK) have a higher risk of HSV keratitis. Because of this, HSV keratitis should be …

An Unusual Case Of Cardiogenic Shock: Coronary Artery Vasospasms, Amanda Bergeron, Maks Mihalj

Journal of Shock and Hemodynamics

Coronary artery vasospasms may occur in one or multiple coronary arteries, typically causing transient chest pain or angina. Although rare, it can lead to lethal cardiac arrhythmias, cardiac arrest, or cardiogenic shock and is often misdiagnosed. We report a case of a young man with an atypical presentation of generalized coronary vasospasm leading to cardiac arrest and subsequent cardiogenic shock. The patient required support with veno-arterial extracorporeal membrane oxygenation and Impella. We discuss the risk factors, diagnosis, and treatment of this rare condition.

Vegetation Dieback In The Mississippi River Delta Triggered By Acute Drought And Chronic Relative Sea-Level Rise, Tracy Elsey-Quirk, Austin Lynn, Michael Derek Jacobs, Rodrigo Diaz, James T Cronin, Lixia Wang, Haosheng Huang, Dubravko Justic

Faculty, Staff and Student Publications

Vegetation dieback and recovery may be dependent on the interplay between infrequent acute disturbances and underlying chronic stresses. Coastal wetlands are vulnerable to the chronic stress of sea-level rise, which may affect their susceptibility to acute disturbance events. Here, we show that a large-scale vegetation dieback in the Mississippi River Delta was precipitated by salt-water incursion during an extreme drought in the summer of 2012 and was most severe in areas exposed to greater flooding. Using 16 years of data (2007-2022) from a coastwide network of monitoring stations, we show that the impacts of the dieback lasted five years 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 …

Role Of Ectopic Olfactory Receptors In The Regulation Of The Cardiovascular-Kidney-Metabolic Axis, Mitchell R Beito, Sadia Ashraf, Dorcas Odogwu, Romain Harmancey

Faculty, Staff and Student Publications

Olfactory receptors (ORs) represent one of the largest yet least investigated families of G protein-coupled receptors in mammals. While initially believed to be functionally restricted to the detection and integration of odors at the olfactory epithelium, accumulating evidence points to a critical role for ectopically expressed ORs in the regulation of cellular homeostasis in extranasal tissues. This review aims to summarize the current state of knowledge on the expression and physiological functions of ectopic ORs in the cardiovascular system, kidneys, and primary metabolic organs and emphasizes how altered ectopic OR signaling in those tissues may impact cardiovascular-kidney-metabolic health.

Chromosomal 3q Amplicon Encodes Essential Regulators Of Secretory Vesicles That Drive Secretory Addiction In Cancer, Xiaochao Tan, Shike Wang, Guan-Yu Xiao, Chao Wu, Xin Liu, Biyao Zhou, Jiang Yu, Dzifa Yawa Duose, Yuanxin Xi, Jing Wang, Kunika Gupta, Apar Pataer, Jack A Roth, Michael P Kim, Fengju Chen, Chad J Creighton, William K Russell, Jonathan M Kurie

Cancer cells exhibit heightened secretory states that drive tumor progression. Here, we identify a chromosome 3q amplicon that serves as a platform for secretory regulation in cancer. The 3q amplicon encodes multiple Golgi-resident proteins, including the scaffold Golgi integral membrane protein 4 (GOLIM4) and the ion channel ATPase Secretory Pathway Ca2+ Transporting 1 (ATP2C1). We show that GOLIM4 recruits ATP2C1 and Golgi phosphoprotein 3 (GOLPH3) to coordinate calcium-dependent cargo loading and Golgi membrane bending and vesicle scission. GOLIM4 depletion disrupts the protein complex, resulting in a secretory blockade that inhibits the progression of 3q-amplified malignancies. In addition to its role …

For patients with high-risk or relapsed/refractory acute myeloid leukemia (AML), allogeneic stem cell transplantation (allo-HSCT) and the graft-versus-leukemia effect mediated by donor T cells, offer the best chance of long-term remission. However, the concurrent transfer of alloreactive T cells can lead to graft-versus-host disease that is associated with transplant-related morbidity and mortality. Furthermore, ∼60% of patients will ultimately relapse after allo-HSCT, thus, underscoring the need for novel therapeutic strategies that are safe and effective. In this study, we explored the feasibility of immunotherapeutically targeting neoantigens, which arise from recurrent nonsynonymous mutations in AML and thus represent attractive targets because they …

The Ins And Outs Of Wide-Awake Hand Surgery, Molly Milano

Bone Bulletin

Introduction

As the name might imply, “wide awake local anesthesia no tourniquet” (WALANT) is a surgical method to perform hand surgery using only a local anesthetic without the use of a tourniquet or any sedation and general anesthetics. The WALANT technique takes advantage of the vasoconstrictive effects of epinephrine combined with the local anesthetic effects of lidocaine to create a surgical field that does not require a tourniquet or general anesthesia.¹ The main contributor is epinephrine, which decreases bleeding in the surgical field while also lengthening lidocaine’s absorption and effect.² When first introduced to the surgical world, the …

Examining The Role Of Augmented Reality In Total Hip Arthroplasty, Joseph Raphael

Bone Bulletin

Background

In 2023, it was reported that total hip arthroplasty (THA) was the main and effective surgical treatment for advanced hip osteoarthritis, osteonecrosis, and rheumatoid arthritis.¹ As the population ages, the number of annual THA procedures is projected to grow and reach 635,000 by the year 2030.² As such, further improving outcomes in THA will benefit this large population. On average age for individuals who sustain a hip fracture is 80 years old and the lifetime prevalence of hip fractures is 20% in women and 10% in men.³ Fracture reduction and internal fixation or arthroplasty are often …

The Role Of Psychological Readiness In Recovery From Acl Injury In Female Athletes, Samantha Meacock

Bone Bulletin

The Anterior Cruciate Ligament (ACL) injury is common in sports, with female athletes facing a disproportionately higher risk in comparison to male athletes.¹ This susceptibility is the result of a complex relationship between various factors including anatomical, biomechanical, hormonal, neuromuscular, and environmental influences.² In addition, the unique challenges that females face with respect to sports, violence, body image, and family planning create additional stressors that may further contribute to an increased risk for injury.^3,4 Following ACL Reconstruction (ACLR) surgery, these gender discrepancies carry over into recovery as female athletes exhibit decreased rates of return to sport (RTS) …

Shoulder Arthroplasty In Patients With Inflammatory Arthritis: Preoperative And Perioperative Management Of Disease Modifying Anti-Rheumatic Drug Therapy, Daniel Kwak

Revolutionizing Orthopaedics: Exploring The Therapeutic Potential Of Stem Cells, Harrison Fellheimer

Bone Bulletin

The development of stem cells holds the key to a revolutionary era in medicine, unlocking multisystem processes that will help restore normal function in the human body. Stem cells are undifferentiated cells that have the capability to give rise to cells of the same type, and from which new cells can arise through the process of differentiation. Several sources of stem cells can be broadly categorized into three main types: embryonic stem cells (ESC), adult stem cells, and induced pluripotent stem cells (iPSCs).¹

The Swi/Snf Atp-Dependent Chromatin Remodeling Complex In Cell Lineage Priming And Early Development, Dhurjhoti Saha, Srinivas Animireddy, Blaine Bartholomew

Faculty, Staff and Student Publications

ATP dependent chromatin remodelers have pivotal roles in transcription, DNA replication and repair, and maintaining genome integrity. SWI/SNF remodelers were first discovered in yeast genetic screens for factors involved in mating type switching or for using alternative energy sources therefore termed SWI/SNF complex (short for SWItch/Sucrose NonFermentable). The SWI/SNF complexes utilize energy from ATP hydrolysis to disrupt histone-DNA interactions and shift, eject, or reposition nucleosomes making the underlying DNA more accessible to specific transcription factors and other regulatory proteins. In development, SWI/SNF orchestrates the precise activation and repression of genes at different stages, safe guards the formation of specific cell …

Faculty, Staff and Students Publications

Human noroviruses, globally the main cause of viral gastroenteritis, show strain specific affinity for histo-blood group antigens (HBGA) and can successfully be propagated ex vivo in human intestinal enteroids (HIEs). HIEs established from jejunal stem cells of individuals with different ABO, Lewis and secretor geno- and phenotypes, show varying susceptibility to such infections. Using bottom-up glycoproteomic approaches we have defined and compared the N-linked glycans of glycoproteins of seven jejunal HIEs. Membrane proteins were extracted, trypsin digested, and glycopeptides enriched by hydrophilic interaction liquid chromatography and analyzed by nanoLC-MS/MS. The Byonic software was used for glycopeptide identification followed by hands-on …

The basal breast cancer subtype is enriched for triple-negative breast cancer (TNBC) and displays consistent large chromosomal deletions. Here, we characterize evolution and maintenance of chromosome 4p (chr4p) loss in basal breast cancer. Analysis of The Cancer Genome Atlas data shows recurrent deletion of chr4p in basal breast cancer. Phylogenetic analysis of a panel of 23 primary tumor/patient-derived xenograft basal breast cancers reveals early evolution of chr4p deletion. Mechanistically we show that chr4p loss is associated with enhanced proliferation. Gene function studies identify an unknown gene, C4orf19, within chr4p, which suppresses proliferation when overexpressed-a member of the PDCD10-GCKIII kinase module …

Kimmel Cancer Center Faculty Papers

Dysregulated nuclear-cytoplasmic trafficking has been shown to play a role in oncogenesis in several types of solid tumors and hematological malignancies. Exportin 1 (XPO1) is responsible for the nuclear export of several proteins and RNA species, mainly tumor suppressors. KPT-330, a small molecule inhibitor of XPO1, is approved for treating relapsed multiple myeloma and diffuse large B-cell lymphoma. Cutaneous T-cell lymphoma (CTCL) is an extranodal non-Hodgkin lymphoma with an adverse prognosis and limited treatment options in advanced stages. The effect of therapeutically targeting XPO1 with KPT-330 in CTCL has not been established. We report that XPO1 expression is upregulated in …
