Relcovaptan: A Promising Therapeutic Agent In Traumatic Spinal Cord Injury That Acts By Modulating Newly Identified Transcriptional Regulators Of Aquaporins Compared To Tolvaptan, Şeyma İş, Duygu Ceman, Meri̇h İş, Neşe Keser, Şaban Teki̇n

Turkish Journal of Medical Sciences

Background/aim: Every year, hundreds of thousands of people worldwide suffer from traumatic spinal cord injury (tSCI), which causes irreversible damage, edema, and inflammation. Despite its devastating impact, no safe and effective medication is available. Edema formation is one of the earliest pathological events in tSCI, beginning within minutes after injury. Cytotoxic edema progresses to vasogenic edema, exacerbating irreversible damage. Our study aimed to investigate a therapeutic approach targeting cytotoxic edema in the acute phase of tSCI to improve treatment outcomes. Aquaporins (AQPs) are crucial in edema formation and tSCI pathogenesis. Vasopressin, also known as the antidiuretic hormone, modulates Aqp expression …

The Impact Of Tizanidine, Thiocolchicoside, And Cyclobenzaprine On Vascular Function In Ovariectomized Rats, Sümeyye Nur Gürsoy, Tolga Esmerli̇gi̇l, Uğur Berkay İnce, Turhan Dost, Buket Demi̇rci̇

Turkish Journal of Medical Sciences

Background/aim: Menopause is associated with increased vascular risk. This study investigated the effects of 3 centrally acting muscle relaxants—tizanidine (TZ), thiocolchicoside (TCC), and cyclobenzaprine (CBZ)—on vascular reactivity in ovariectomized (OVX) rats as a model of menopause.

Materials and methods: Body weight, blood glucose, blood pressure, and heart rate were recorded, and the rats underwent oophorectomy surgery. Eight weeks after the operation, the rats were divided into 5 groups: sham operated rats, OVX rats, OVX rats treated with TZ (OVX + TZ), OVX rats treated with TCC (OVX + TCC), and OVX rats treated with CBZ (OVX + CBZ).

Natural Progression Of Meningeal Lymphatic Dysfunction In App/Ps1 Mice Creates A Critical Window For Alzheimer’S Disease Intervention, Zilong Shen, Xibin Zhou, Chunxiang Zhou

Turkish Journal of Medical Sciences

Background/aim: Meningeal lymphatic vessels (mLVs) facilitate the clearance of toxic metabolites like amyloid-beta (Aβ) from the central nervous system. Dysfunction in MLVs is implicated in Alzheimer’s disease (AD). However, current knowledge relies on exogenous intervention models that fail to capture spontaneous mLV decline during AD progression. In this study, we investigated the age-dependent correlation between mLV/deep cervical lymph node (dCLN) dysfunction and Aβ pathology in APP/PS1 mice under noninterventional conditions.

Materials and methods: APP/PS1 and wild-type (WT) mice at 3, 6, and 9 months of age were evaluated. Cognitive function was tested using the Morris water maze. mLV/dCLN drainage was …

Turkish Journal of Medical Sciences

Background/aim: Moltkia coerulea, a medicinal plant traditionally used for its neuroprotective properties, contains diverse phenolic compounds. However, its mechanisms of action in neuroinflammation remain unclear. We hypothesized that extracts of M. coerulea may protect microglial cells from lipopolysaccharide (LPS)-induced oxidative stress and apoptosis by modulating reactive oxygen species (ROS) and caspase-3 activity.

Materials and methods: Aqueous and methanol extracts (5–50 μg/mL) were tested in BV-2 microglial cells. Cell viability was assessed by MTT assay, while ROS generation and caspase-3 activity were measured using fluorescence-based kits. The effective concentration (10 μg/mL) was selected for mechanistic assays based on viability data and …

Reimagining Nurse Education: Virtual Reality & Didactic Education For Better Nurse Handoff And Documentation, Haley M. Whalen

Master's Projects and Capstones

Setting: The pediatric perianesthesia unit (pre-operative and post-anesthesia care unit). Problem: Gaps in perianesthesia documentation contribute to poor handoff communication, leading to adverse events and increased hospital costs. Additionally, inconsistent documentation reduces clarity and consistency during handoffs. Context: Staff in the microsystem reported low confidence scores with required OP-Time documentation, inconsistent workflows, and I-PASS handoff expectations. These factors contribute to incomplete charting and a lack of standardization across providers. Interventions: A two-part educational intervention was conducted, consisting of eight sessions. The first component is a Virtual Reality (VR) simulation that demonstrates an accurate perianesthesia I-PASS handoff. The second …

Electrochemical Detection Of No And Ca2+ During Cold Atmospheric Plasma Treatment Of Acute Wounds: Sensor Selectivity And Stability In The Plasma-Bio-System, Jonathan E. Thomas, Kristina Pattison, Suneel Kumar, Gagana Karkada, Duncan Trosan, Aunic Goodin, Jason Rainone, Dnyaneshwari Rananavare, Vandana Miller, Francois Berthiaume, Katharina Stapelmann

Kimmel Cancer Center Faculty Papers

Cold atmospheric plasmas (CAP) are a versatile tool in medical applications like wound healing. Its therapeutic benefits are partially attributed to the generation of biologically active reactive oxygen and nitrogen species (RONS). Characterization of RONS, however, typically only occurs after treatment. Here we report the first real-time in situ detection of CAP-generated nitric oxide (NO), and the simultaneous detection of cellular calcium ions (Ca²⁺) release using electrochemical sensors during CAP treatment of murine wounds. In vivo, NO rose rapidly within the first minute of CAP treatment but accumulated less overall than in PBS, reflecting reactions with wound-bed targets. In situ …

Most HIV-negative individuals exposed to Mycobacterium tuberculosis (Mtb) control infection as latent TB infection (LTBI), but HIV co-infection greatly increases progression to tuberculosis (TB), the leading cause of death in people living with HIV (PLHIV). Although combination antiretroviral therapy (cART) reduces LTBI reactivation, immune control of Mtb is not fully restored, as shown by persistent TB incidence in PLHIV on cART. In macaques, skewed pulmonary effector memory CD4⁺ T-cell (TEM) responses and new TB lesions persist despite cART. We hypothesize that concurrent anti-TB therapy with cART would improve bacterial control and immune restoration compared to cART alone. Using …

Agpat2 Acts At The Crossroads Of Lipid Biosynthesis And Drp1-Mediated Er Morphogenesis, Yoshihiro Adachi, Mauricio Torres, Allen H Hunter, Woo Jung Cho, Meixia Pan, Xianlin Han, Guangwei Du, Ling Qi, Miho Iijima, Hiromi Sesaki

Faculty, Staff and Student Publications

The morphology of the endoplasmic reticulum (ER), characterized by central sheets and peripheral tubules, is controlled by membrane-shaping proteins. However, the role of lipids in ER morphogenesis remains elusive, despite the ER being the major site for lipid synthesis. Here, by examining the role of eighteen phosphatidic acid (PA)-generating enzymes in ER morphology, we identify lysophosphatidic acid acyltransferase 2 (AGPAT2) as a critical factor in mouse and human cells. AGPAT2 produces PA in the glycerophospholipid/triacylglycerol biosynthesis pathway, and its mutations cause congenital generalized lipodystrophy. We find that AGPAT2-generated PA drives ER tubulation through gene knockout, 3D structural analysis by FIB-SEM, …

In The Mouth Or In The Gut? Innovation Through Implementing Oral And Gastrointestinal Health Science In Chronic Pain Management, Jo Nijs, Burel R Goodin, Et Al.

2020-Current year OA Pubs

Recent scientific advances point towards an important role for oral and gastrointestinal health in people with chronic pain. Poor oral health (e.g., periodontitis, tooth loss) is observed in subgroups of the chronic pain population, including abdominal pain, low back pain, fibromyalgia, and rheumatoid arthritis. In addition to poor oral health, studies have also revealed altered intestinal microbiota compositions in various types of chronic pain, including people with chronic low back pain, knee osteoarthritis, visceral pain, fibromyalgia, tinnitus, and migraine. While overweight/obesity contributes to the likelihood of gut dysbiosis, normal-weight individuals with chronic pain also more often present with poor gut …

Conservation Of Cis-Regulatory Codes Over Half A Billion Years Of Evolution, Yohey Ogawa, Yu Liu, Connie A Myers, Ala Morshedian, Gordon L Fain, Alapakkam P Sampath, Joseph C Corbo

2020-Current year OA Pubs

Identifying homologous cell types across species is essential for understanding cell type evolution. The retina is ideal for comparative analysis because its six major cell classes have persisted since the origin of vertebrates more than half a billion years ago. Here, we show that the retina's conserved cellular architecture is mirrored by deep conservation of the cis-regulatory codes that govern gene expression. Through single-cell chromatin accessibility analysis of lamprey, fish, bird, and mammalian retinas, we demonstrate cross-species conservation of cis-regulatory codes in all retinal cell classes despite extensive turnover of cis-regulatory regions. Conservation manifests as clustering of high-affinity transcription factor …

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

The study investigates the sex-specific effects of the pluripotency factor OCT4 deficiency in endothelial cells (ECs) on angiogenesis. OCT4 is known for its role in embryonic stem cells, but we recently found that it plays a protective role in ECs during atherosclerosis. Herein, we utilized cultured mouse aortic ECs (MAECs) and several in vivo models, including skin wounding, melanoma tumor implantation, and hindlimb ischemia, to explore the role of OCT4 in angiogenesis in both male and female mice. Our findings revealed significant sexual dimorphism in wild type mice, along with sex differences in responses to OCT4 deficiency across all three …

Structural Basis Of Panx1 Permeation And Positive Modulation By Mefloquine, Yangyang Li, Zheng Ruan, Junuk Lee, Ian Orozco, Edward Zhou, Juan Du, Wei Lü

Department of Biochemistry and Molecular Biology Faculty Papers

Purinergic signaling relies on ATP release through exocytosis and large-pore channels. Large-pore channels permeate both small anions like chloride and large signaling molecules like ATP, but how this broad cargo selectivity is structurally controlled remains elusive. Here we investigate PANX1, a prototypical large-pore channel, and uncover structural plasticity at the extracellular entrance formed by seven tryptophan (W74) residues. The W74 sidechains are flexible, sampling conformations that range from a constricted state permissive only to chloride to a dilated state compatible with ATP. These states are coupled to variable cation-π interactions between W74 and arginine 75 (R75), suggesting a mechanism for …

Delayed Delivery Of Antibiotics By Ultrasound-Mediated Rupture Of Polylactic Acid Pockets: In Vitro And In Vivo Studies, Selin Isguven Billmyer, Priscilla Machado, Ryan Tomlinson, Lauren J. Delaney, Ji-Bin Liu, Alexander H Harris, Eric Mclaughlin, Noreen J. Hickok, Flemming Forsberg

Department of Radiology Faculty Papers

Surgical site infections are a devastating complication of instrumented orthopaedic surgery, particularly in the spine. Bacterial biofilms, once formed on the implant surfaces, exhibit antibiotic tolerance and immune escape, which lead to treatment challenges. Up to 9% of instrumented spine surgeries result in infection, despite the use of systemic antibiotics and local, powdered antibiotics for prophylaxis. The bacteria that survive the initial prophylaxis may be susceptible to a second, high dose of antibiotic prophylaxis prior to establishing at the site. Hence, we designed a local drug delivery system consisting of polylactic acid (PLA) film pockets that can be noninvasively triggered …

Variable expressivity of disease-associated variants implies a role for secondary variants that modify clinical features. We assessed the effects of modifier variants on the clinical outcomes of 2,455 individuals with primary variants. Among 124 families with the 16p12.1 deletion, distinct rare and common variant classes conferred risks for specific developmental features, including short tandem repeats for neurological defects. Network analysis suggested distinct mechanisms involving 16p12.1 genes and secondary variants specific to each proband. Within disease and population cohorts of 976 individuals with the 16p12.1 deletion, we found opposing effects of secondary variants on clinical features across ascertainments. Additional analysis of …

Parkinson's disease (PD), Dementia with Lewy bodies (DLB), and multiple system atrophy (MSA), are characterized by the misfolding and aggregation of alpha-synuclein (αSyn). Compelling evidence showed that αSyn aggregates exist as distinct conformational strains in different synucleinopathies. Recently, we reported that the αSyn Seed Amplification Assay (αSyn-SAA) can amplify and distinguish αSyn strains from PD and MSA. In this study, we investigate whether MSA-seeded, SAA-amplified αSyn fibrils retain the biological and structural properties of the αSyn seeds present in MSA brains. We study the biological activities of both brain-derived and SAA-amplified αSyn aggregates using an αSyn "biosensor" cell model and …

Elevated Lactate In Aml Bone Marrow Contributes To Macrophage Polarization Via Gpr81 Signaling., Celia A Soto, Maggie L Lesch, Jennifer L Becker, Azmeer Sharipol, Amal Khan, Xenia L Schafer, Zhewen Li, Amanda R Streeter, Michael W Becker, Joshua C Munger, Benjamin J Frisch

Oncology Articles

Interactions between acute myeloid leukemia (AML) and the bone marrow microenvironment (BMME) are critical to leukemia progression and chemoresistance. In the solid tumor microenvironment, altered metabolite levels contribute to cancer progression. We performed a metabolomic analysis of AML patient bone marrow serum, revealing increased metabolites compared to age- and sex-matched controls. The most highly elevated metabolite in the AML BMME was lactate. Lactate signaling in solid tumors induces immunosuppressive tumor-associated macrophages and correlates with poor prognosis. This has not yet been studied in the leukemic BMME. Herein, we describe the role of lactate in the polarization of leukemia-associated macrophages (LAMs). …
