Microglial Expression Of Serotonin Receptors Reveals Parallel Regulation Of 5-Ht2b And Bdnf In The Rat Hippocampus, Andrei Turkin, Maria Sidorova, Ekaterina Kurilova, Natalia Alenina, Oksana Tuchina, Friederike Klempin

School of Graduate Studies Faculty Publications

Growing evidence suggests that psychiatric disorders are characterized by a prolonged inflammatory state, which may influence the efficacy of compounds targeting serotonin. Serotonin is a key signaling molecule in neuroplasticity of the adult hippocampus and involved in antidepressant action. Recent in vitro studies indicate the neurotransmitter may also facilitate the response to inflammation and potentially modulate microglial function towards neuroprotection. Using Tph2−/− rats depleted of brain serotonin, we examined microglial expression of various serotonin receptors (5-HTRs) in vivo in both the hippocampus and prefrontal cortex and assessed mRNA levels of cytokines and brain-derived neurotrophic factor (BDNF). We observed age-dependent and …

Concentric Macular Rings And Oct Corrugations In Foveal Hypoplasia: Proof Of Concept For An Optical Interference Mechanism, Ari August, Ralph Eagle, Tatyana Milman, Rebecca Procopio, Bruce Schnall, Jose Pulido

Wills Eye Hospital Papers

BACKGROUND: Concentric macular rings (CMR) and Henle fiber layer (HFL) corrugations, potential clinical biomarkers of foveal hypoplasia, have been observed in laser fundus photographs and optical coherence tomography (OCT) images, respectively. Some believe these findings represent true anatomical structural changes while others hypothesize that they are artifacts of interference; however, to our knowledge, no previous study has provided evidence to support either theory.

METHODS: This retrospective case series analyzed CMR and OCT corrugations in 3 patients (6 eyes) with foveal hypoplasia. Dark fringe diameters of CMR at different wavelengths (λ: red = 635, green = 532, blue = 488 nm) …

Application Of Flexible Endoscopy For Gastrointestinal Foreign Body Removal In A Leopard Gecko (Eublepharis Macularius), Jang-Hee Han, Seung Yoon Ahn, Do Na Lee, Seong Chan Yeon

The Thai Journal of Veterinary Medicine

A male captive-bred leopard gecko (Eublepharis macularius) presented with a history of inadvertent ingestion of a rubber tip from forceps during feeding. The foreign body was impalpable on physical examination, while radiographic evaluation confirmed its presence in the stomach. Considering the procedural risks associated with invasive surgical interventions, endoscopic retrieval under general anesthesia was pursued. An initial attempt using a 2.8 mm superfine flexible endoscope with 0.8 mm forceps was unsuccessful due to insufficient stability, which hindered effective navigation to the foreign body. In contrast, a second attempt using a larger 9.2 mm flexible endoscope with 2.3 mm …

School of Graduate Studies Faculty Publications

The gut microbiome has emerged as a key regulator of human health, influencing not only metabolism and immunity but also the development and treatment of cancer. Mounting evidence suggests that microbial dysbiosis contributes to oncogenesis by driving chronic inflammation, producing genotoxic metabolites, altering bile acid metabolism, and disrupting epithelial barrier integrity. At the same time, the gut microbiome significantly modulates the host response to oncotherapies including chemotherapy, radiotherapy, and especially immunotherapy, where microbial diversity and specific taxa determine treatment efficacy and toxicity. This review synthesizes current evidence on the role of the gut microbiome in both oncogenesis and oncotherapies, focusing …

Development And Characterization Of Non-Viral Delivery Systems For Pulmonary Delivery Of Nucleic Acid Therapeutics, Kasturi Siddhanta

Theses & Dissertations

The development of non-viral delivery systems for pulmonary delivery of nucleic acid therapeutics is driven by the need for safer and more accessible approaches to treat lung diseases, while avoiding the systemic side effects and immune responses associated with viral vectors. Such systems encompass both non-invasive inhalation-based platforms, and systemically administered platforms designed to achieve localized lung delivery. These strategies aim to enable high drug concentrations at the site of action, rapid onset of therapeutic effect, and greater therapeutic efficacy than existing treatments. Designing effective pulmonary delivery systems requires precise optimization of particle properties—including size, morphology, surface characteristics, cell-specific targeting, …

Myocardial Pi3k-Akt Pathway And Cardiovascular Disease Etiology, Bryson Lovorn, Brennan Kaplan

Student Scholar Symposium

Cardiovascular diseases (CVD) are the leading causes of death in the United States according to recent data from the Center for Disease Control (CDC). Myocardial infarctions, heart attacks, Coronary Artery Disease, ischemic reperfusion injuries, and hypertrophic cardiomyopathies represent common pathologies leading to the hospitalization of Americans. The etiologies of these diseases vary, however there is a common link. The phosphatidylinositol-3-kinase (PI3K) AKT pathway is a cellular pathway that is commonly overexpressed or repressed in myocytes. The human body is in an active limbo to maintain homeostasis. At a cellular level this can be simplified to a delicate balance between cell …
