Research Colloquium

Cervical cancer (CxC) is a leading cause of mortality and morbidity among women worldwide. Current chemotherapeutic agents for CxC have shown systemic toxicity in CxC patients. Ormeloxifene (ORM) is a non-toxic and non-steroidal drug with well-defined pharmacokinetic and pharmacodynamic properties in humans. In this study, we introduce a new analogue of ormeloxifene, Bromo-ormeloxifene (Br-ORM), which demonstrates enhanced therapeutic efficacy against CxC in both in vitro and in vivo models. We investigated Br-ORM's effects on CxC cell growth through colony formation and MTS assays, alongside molecular docking studies with βcatenin using AutoDock4. Furthermore, we analyzed the influence of Br-ORM on the …

The trends and disparities in AAMR were examined using descriptive statistics and graphical methods. The AAMR due …

Epac1 Deletion Attenuates Müller Glial Pathological Activation And Mitigates Retinal Neurodegeneration In Ischemia-Induced Retinopathy, Shuizhen Shi, Fan Xia, Zhongqiao Lu, Erick Palacios, Fang Mei, Massoud Motamedi, Xiaodong Cheng, Hua Liu, Wenbo Zhang

The Brown Foundation: Institute of Molecular Medicine

Introduction: Ischemia-induced retinopathies, such as retinopathy of prematurity and proliferative diabetic retinopathy, are major causes of vision loss. Both pathological neovascularization and neuronal damage contribute to vision impairment in these conditions, yet current therapies primarily target neovascularization and may further compromise neuronal health.

Objectives: Cyclic AMP (cAMP) is a widely recognized second messenger regulating diverse physiological and pathological processes. Exchange protein directly activated by cAMP (Epac) is a recently identified effector of cAMP signaling. This study aimed to investigate the role of Epac1 in ischemia-induced retinopathy and elucidate its underlying mechanisms using a mouse model of oxygen-induced retinopathy (OIR).

Metabolic Shifts In Murine Inner Ears Mimicking Erythrocytes And Plasma Reveal Diagnostics And Early Predictors For Age-Related Hearing Loss, Qi Guo, Zhenjiang Li, Cheng Luo, Changhan Chen, Xi Long, Yidan Wang, Qingfen Qiang, Fang Yu, Wuping Liu, Yujin Zhang, Rodney E Kellems, Yang Xia

Faculty, Staff and Student Publications

Age-related hearing loss (ARHL) is a major public health concern, driven by the interplay of multiple factors. Here, we reveal spatiotemporal metabolic shifts in murine inner ears mirroring erythrocytes and plasma. Isotope-labeled glucose tracing demonstrates a metabolic rerouting favoring glycolysis over the pentose phosphate pathway, alongside downregulation of the tricarboxylic acid cycle, indicating impaired energy production and redox homeostasis. Accumulation of medium- and long-chain acylcarnitines further exacerbates lipotoxicity. Notably, age-dependent depletion of arginine, lysine, proline, and glycine disrupts the arginine-polyamine-urea cycle. Translationally, UK Biobank plasma metabolomics links omega-6 fatty acids, linoleic acid, glycine, and albumin to ARHL resilience, while branched-chain …

Faculty, Staff and Students Publications

Rett syndrome is a rare neurodevelopmental disorder that significantly impairs bipedal postural control and walking ability. This study quantifies the gait characteristics of 22 females with Rett syndrome (divided into 3 age groups) and compares them with age-matched neurotypical females. Bilateral sagittal plane joint angles of the hip, knee, and ankle were analyzed. Measures included joint range of motion, stride time, peak angular velocity, angle-angle diagrams, phase portrait areas, and asymmetries. Results revealed reduced joint range of motion and angular velocity in individuals with Rett syndrome, as well as greater asymmetries in gait parameters reflecting disruptions in bilateral coordination. Phase …

Blue-Shifted Ancyromonad Channelrhodopsins For Multiplex Optogenetics, Elena G Govorunova, Oleg A Sineshchekov, Hai Li, Yueyang Gou, Hongmei Chen, Shuyuan Yang, Yumei Wang, Stephen Mitchell, Alyssa Palmateer, Leonid S Brown, François St-Pierre, Mingshan Xue, John L Spudich

Duncan NRI Faculty and Staff Publications

Light-gated ion channels from protists (channelrhodopsins or ChRs) are optogenetic tools widely used for controlling neurons and cardiomyocytes. Multiplex optogenetic applications require spectrally separated molecules, which are difficult to engineer without disrupting channel function. Scanning numerous sequence databases, we identified three naturally blue-shifted ChRs from ancyromonads. They form a separate branch on the phylogenetic tree and contain residue motifs characteristic of anion ChRs (ACRs). However, only two conduct chloride, whereas the closely related Nutomonas longa homolog generates inward cation currents in mammalian cells under physiological conditions, significantly exceeding those by previously known tools with similar spectral maxima (peak absorption at …

Retinopathy Of Prematurity: History, Diagnosis, And Treatment, Henry Nguyen, Bs, Ayra Khan, Bs, Flavius Beca, Md, Yoshihiro Yonekawa, Md

inSIGHT

Abstract
Retinopathy of prematurity (ROP) is a vasoproliferative disorder that remains a leading cause of preventable childhood blindness worldwide. This review examines the current understanding of ROP's pathophysiology, prevention, diagnosis, and treatment. ROP develops in two distinct phases: an initial hyperoxic phase, denoted by decreased levels of vascular endothelial growth factor (VEGF), followed by a hypoxic phase, where increasing levels of VEGF trigger pathological neovascularization. Currently, the most effective therapeutics for management are laser photocoagulation and anti-VEGF therapies. The current paradigm in ROP management is shifting toward earlier identification, better risk stratification, and integration of digital screening technologies and standardizing …

Comparing Approaches To Refractive Laser Eye Surgery, Tejal Patel, Ba

inSIGHT

Laser eye surgery is one of the most common outpatient ophthalmic procedures performed in the United States. Most patients choose laser eye surgery because they want to decrease the need for daily glasses or contact lens wear. In the past 10 years, over 700,00 eyes have been treated with some type of laser surgery (1).¹ While colloquially known as “LASIK,” there are three major types of laser eye surgeries: Photorefractive Keratectomy (PRK), Laser in Situ Keratomileusis (LASIK), and Small Incision Lenticule Extraction (SMILE). These surgeries all fundamentally rely on the same concept of using a laser to reshape the …

A Day In The Life Of An Orbital And Oculoplastic Surgeon, Alexis Duffy, Ba

inSIGHT

Have you ever heard of an oculoplastic surgeon before? And if so, ever wonder what they do or how they differ from plastic surgeons? Treating the periocular region requires an in-depth understanding not only of the eye, but also its complex interplay with adjacent orbital, sinus, and craniofacial anatomy; there is much more than meets the eye! The most common pathway to become an oculoplastic surgeon includes completion of a four-year ophthalmology residency, followed by one to two years of subspecialized oculoplastic fellowship. Oculoplastic fellowships provide surgical and medical experience managing pathology of the eyelid and orbit, and different programs …

Idiopathic Intracranial Hypertension: A Comprehensive Review Of Diagnosis And Management, Sriya Sadhu, Bs

inSIGHT

Idiopathic intracranial hypertension (IIH) is a critical vision-threatening disease that has been on the rise over the past 10 years.¹ IIH is a condition involving an increase in intracranial pressure due to an unknown (idiopathic), nonspecific cause. The previous alternative name of IIH, "pseudotumor cerebri" (false brain tumor), was given because IIH can present with symptoms similar to those that are seen in several brain tumors - severe headaches, seizures, nausea, and vision deterioration. IIH has a primarily female predominance and a strong association with obesity. As the rates of obesity increase, the prevalence of IIH is similarly expected …

Recent Trends In The Ophthalmology Match, Michael Pratt, Ma

inSIGHT

Ophthalmology remains a competitive field to match for residency, with applications far outnumbering available positions. The criteria for a successful match are unclear owing to differences in data reporting from the SF Match system as compared to the National Residency Match Program, a relatively low volume of scholarly research about the ophthalmology match, and the transition of the USMLE Step 1 exam to pass/fail grading in 2022. This narrative review, while not intended as a guide to become a competitive applicant for residency, will summarize the 2024 ophthalmology match cycle results, report the specific match rate for Sidney Kimmel Medical …

Vascular, Immunological, And Mechanical Factors In Normal Tension Glaucoma: A Multidimensional Approach To Pathogenesis, Rachel E. Cain

inSIGHT

Glaucoma is characterized by progressive degeneration of retinal ganglion cells leading to optic neuropathy and visual field loss.

The major risk factor for glaucoma is elevated intra-ocular pressure (IOP) (Fig. 1). However, 30-40% of patients with glaucoma have normal IOP, leading to the classification of normal-tension glaucoma (NTG) (Fig. 1 C, E).^1,2 The prevalence of NTG varies between populations, with Asians having the highest prevalence (77- 92%), followed by Africans (57%), and Caucasians (30-39%).³ In a landmark study, the collaborative normal tension glaucoma study group (CNTGS) showed that a 30% reduction in IOP in NTG patients slowed the …

Delayed Diagnosis Of Systemic Lupus Erythematosus Presenting As Autoimmune Hemolytic Anemia: A Case For Heightened Clinical Suspicion, Diana Acosta Pozo, Luis Álvarez Pérez

Research Colloquium

Background: Systemic Lupus Erythematosus (SLE) is a chronic autoimmune disease characterized by multisystem involvement, including hematologic manifestations. Autoimmune Hemolytic Anemia (AIHA), though an established feature, is relatively uncommon and may occur early or in isolation. When AIHA presents without overt systemic symptoms, the underlying autoimmune etiology may be overlooked, resulting in delays in diagnosis and treatment. Prompt recognition is essential to prevent unnecessary interventions and prolonged morbidity.

Educational Services And Language Congruency In Low-Income Children Who Are Deaf Of Hard-Of-Hearing, Courtney J. Austin, Dylan Chan, Jihyun Stephans

Research Colloquium

Background: Children who are deaf or hard-of-hearing (DHH) are required by United States law to have access to educational services through the Individuals with Disabilities in Education Act (IDEA). However, access to language-congruent providers, as well as supplemental services, varies considerably. Household income is associated with poorer hearing care access and outcomes in DHH children. We predict that access to supplemental, language-congruent DHH services is poorer in DHH children from lower-income homes.

Methods: This is a secondary, ad hoc exploratory study of DHH children aged 0-27 months enrolled in a randomized clinical trial (CT.gov: NCT04928209). Children were enrolled across all …

A Puzzling Case Of Visual Disturbances Leads To A Fatal Neurodegenerative Diagnosis, Courtney J. Austin, Aaron Carrillo, Jennifer Rojas Huen, Victoria Parada

Research Colloquium

Background: Creutzfeldt-Jakob disease (CJD) is a rare neurodegenerative disease in which early diagnosis is complicated by the presence of early non-specific and atypical presentations. Sporadic CJD (sCJD), the most common type of CJD, is caused by the spread of a disease-forming prion known as PrPSc. PrPSc multiplies and binds to the normal form of prion, or PrP, converting it to an abnormal, structurally altered disease form that spreads throughout the brain. sCJD can initially present with six different phenotypes: cognitive, affective, classic, visual (Heidenhain variant), atactic (Oppenheimer-Brownell variant), and indeterminate. The classic presentation of CJD includes rapidly progressive dementia with …

Optimizing Antibiotic Stewardship In Pneumonia: Evidence-Based Protocols For Enhanced Treatment And Resistance Reduction In A University-Affiliated Community Hospital, Carlos Luis Alejos, Jennifer Rojas Huen, Joan Beatrice Capellan, Ricardo Serna, Tejaswini Swamy, Jose Campo Maldonado

Research Colloquium

Introduction: National guidelines recommend early, targeted diagnostics such as respiratory viral panels, procalcitonin testing, Methicillin resistant staphylococcus aureus (MRSA) nasal swabs, and sputum cultures, for the effective management of pneumonia. However, our retrospective review at a university-affiliated community hospital revealed inconsistent application of these tools. These may contribute to excessive use of broad-spectrum antibiotics, higher costs, and increased antimicrobial resistance. The reason is that we aim to implement a standardized pneumonia order set in the electronic medical record (EMR) to improve diagnostic accuracy and antibiotic stewardship.

Methods: We conducted a retrospective chart review of adult inpatients admitted with community-acquired, hospital-acquired, …

Case Report: Familial Hypomagnesemia In A Patient With History Of Hodgkin Lymphoma, Aura M. C. Calderon, Ivan Mogollon, Catherine Matos, Jose Loayza, Everardo Cobos

Research Colloquium

Introduction: Magnesium constitutes an essential electrolyte integral to the functioning of neuromuscular systems, the regulation of cardiovascular parameters, and the facilitation of metabolic processes. Chronic hypomagnesemia may precipitate significant complications, including the onset of arrhythmias and seizures. In cases where hypomagnesemia is refractory to supplementation and manifests in multiple family members, a hereditary tubulopathy, such as Gitelman syndrome (GS), warrants consideration. Gitelman syndrome is classified as an autosomal recessive disorder, resulting from mutations in the SLC12A3 gene, which impairs the thiazide-sensitive sodium-chloride cotransporter located in the distal convoluted tubule.
