Development Of A Synthetic Biomarker System For Early Detection Of Ischemic Stroke, Mason L. Matthies May 2024

Development Of A Synthetic Biomarker System For Early Detection Of Ischemic Stroke, Mason L. Matthies

Honors Thesis

Stroke, particularly Ischemic Stroke (IS) affects millions of individuals across the world each year . Current diagnostic methods like CT scans and MRI imaging have limitations in detecting minor IS due to the limited spatial resolution of the CT scan and the feasibility and access to MRIs warranting a more effective method of early detection. Natural biomarkers are currently ineffective in detecting IS prior to severe damage like rapid cell death (32,000 cells/sec) post arterial blockage because there is minimal amount of natural biomarkers expressed from minor cellular damage . Our proposed Synthetic Biomarker System (SBS) would solve this by …


The Neuroprotective Role Of Lipoxin A4 In Reinstating Blood Brain Barrier Integrity In Neuroinflammatory Disease Processes, Minjal Patel, Nimish Acharya May 2024

The Neuroprotective Role Of Lipoxin A4 In Reinstating Blood Brain Barrier Integrity In Neuroinflammatory Disease Processes, Minjal Patel, Nimish Acharya

Rowan-Virtua Research Day

Background: The blood-brain barrier (BBB), formed by the vascular endothelium, astrocytic foot processes, pericytes, is a highly selective barrier that is responsible for maintaining brain homeostasis and ultimately proper neuronal function. Disruption of the BBB, leading to increased BBB permeability, has been reported in several neurodegenerative diseases, including Alzheimer’s disease (AD) and traumatic brain injury (TBI).1 Loss of BBB integrity leads to the proliferation of pro-inflammatory cytokines, including TNFɑ, IL-1β, and IL-6.2 Moderate inflammation has a beneficial response in the system following an acute injury. However, prolonged inflammation has been known to perturb homeostasis and have …


Relationship Between C-Reactive Protein/Albumin Ratio And Mucocutaneous Symptom Frequency And Disease Severity In Behçet’S Disease, Erdal Pala, Mustafa Bayraktar Apr 2024

Relationship Between C-Reactive Protein/Albumin Ratio And Mucocutaneous Symptom Frequency And Disease Severity In Behçet’S Disease, Erdal Pala, Mustafa Bayraktar

Turkish Journal of Medical Sciences

Background/aim: There is no specific marker that can be applied to determine the severity of Behçet’s disease. The aim of this study is to investigate the potential of C-reactive protein (CRP)/albumin (CAR) ratio as a tool for assessing the severity of Behçet’s disease.Materials and methods: A retrospective crosssectional study was conducted by examining hospital archives. The CRP and albumin levels of Behçet’s disease patients who presented to our dermatology clinic over a three-year period from February 2020 to February 2022 were included, along with the identical laboratory parameters in the control group. The CAR ratio was calculated and statistically compared …


Molecular Mechanisms In Pathophysiology Of Mucopolysaccharidosis And Prospects For Innovative Therapy, Yasuhiko Ago, Estera Rintz, Krishna Sai Musini, Zhengyu Ma, Shunji Tomatsu Jan 2024

Molecular Mechanisms In Pathophysiology Of Mucopolysaccharidosis And Prospects For Innovative Therapy, Yasuhiko Ago, Estera Rintz, Krishna Sai Musini, Zhengyu Ma, Shunji Tomatsu

Department of Pediatrics Faculty Papers

Mucopolysaccharidoses (MPSs) are a group of inborn errors of the metabolism caused by a deficiency in the lysosomal enzymes required to break down molecules called glycosaminoglycans (GAGs). These GAGs accumulate over time in various tissues and disrupt multiple biological systems, including catabolism of other substances, autophagy, and mitochondrial function. These pathological changes ultimately increase oxidative stress and activate innate immunity and inflammation. We have described the pathophysiology of MPS and activated inflammation in this paper, starting with accumulating the primary storage materials, GAGs. At the initial stage of GAG accumulation, affected tissues/cells are reversibly affected but progress irreversibly to: (1) …


High Amniotic Fluid Fractalkine And Mip-1Β Levels Are Associated With Intrauterine Growth Restriction: A Prospective Cohort Study, Şehmus Pala, Remzi Atilgan, Nevin İlhan Jan 2024

High Amniotic Fluid Fractalkine And Mip-1Β Levels Are Associated With Intrauterine Growth Restriction: A Prospective Cohort Study, Şehmus Pala, Remzi Atilgan, Nevin İlhan

Turkish Journal of Medical Sciences

Proinflammatory chemokines have been shown to play crucial roles in implantation, spiral artery invasion, and thefetomaternal immunological response. In this context, we investigated the levels of fractalkine (CX3CL1) and chemokine CC motifligand 4 (CCL4 or MIP-1β) in maternal serum and amniotic fluids in pregnant women with intrauterine growth restriction (IUGR).Materials and methods: This prospective cohort study was carried out at Fırat University Obstetrics Clinic between January 1, 2022 andJuly 1, 2022. Group (G) 1: The control group consisted of 40 pregnant women who underwent elective cesarean section (CS) at 38–40weeks of gestation. G2: A total of 40 pregnant women with …


Innate And Adaptive Immune System Consequences Of Post-Traumatic Stress Disorder, Tatlock H. Lauten, Tamara Natour, Adam J. Case Jan 2024

Innate And Adaptive Immune System Consequences Of Post-Traumatic Stress Disorder, Tatlock H. Lauten, Tamara Natour, Adam J. Case

Journal Articles: Cellular & Integrative Physiology

In the field of psychiatry, biological markers are rarely, if ever, used in the diagnosis of mental health disorders. Clinicians rely primarily on patient histories and behavioral symptoms to identify specific psychopathologies, which makes diagnosis highly subjective. Moreover, therapies for mental health disorders are aimed specifically at attenuating behavioral manifestations, which overlooks the pathophysiological indices of the disease. This is highly evident in posttraumatic stress disorder (PTSD) where inflammation and immune system perturbations are becoming increasingly described. Further, patients with PTSD possess significantly elevated risks of developing comorbid inflammatory diseases such as autoimmune and cardiovascular diseases, which are likely linked …


Leaky Gut And Inflammatory Biomarkers In A Medication Overuse Headache Model In Male Rats, Doğa Vuralli, Hale Gök Dağidir, Elif Abbasoğlu Topa, Hayrunnisa Bolay Belen Jan 2024

Leaky Gut And Inflammatory Biomarkers In A Medication Overuse Headache Model In Male Rats, Doğa Vuralli, Hale Gök Dağidir, Elif Abbasoğlu Topa, Hayrunnisa Bolay Belen

Turkish Journal of Medical Sciences

Medication overuse is common among chronic migraine patients and nonsteroidal antiinflammatory drugs (NSAIDs)are the most frequently overused drugs. The pathophysiological mechanisms underlying medication overuse headache (MOH) are notcompletely understood. Intestinal hyperpermeability and leaky gut are reported in patients using NSAIDs. The aim of the study is toinvestigate the role of leaky gut and inflammation in an MOH model MOH model in male rats.Methods: The study was conducted in male Sprague Dawley rats. There were two experimental groups. The first group was the chronicNSAID group in which the rats received mefenamic acid (n = 8) for four weeks intraperitoneally (ip) and …

The human respiratory and circulatory systems collaborate intricately to ensure oxygen delivery to all cells, which is vital for ATP production and maintaining physiological functions and structures. During limited oxygen availability, hypoxia-inducible factors (HIFs) are stabilized and play a fundamental role in maintaining cellular processes for hypoxia adaptation. First discovered during investigations of erythropoietin production regulation, HIFs influence physiological and pathological processes, including development, inflammation, wound healing, and cancer. HIFs promote extracellular adenosine signaling by enhancing adenosine generation and receptor signaling, representing an endogenous feedback mechanism that curbs excessive inflammation, supports injury resolution, and enhances hypoxia tolerance. This is especially …
