T-tests compared group differences in LPP, cortical thickness, and deep gray matter volumes. …

Small Bowel Obstruction In Postpartum Vaginal Delivery Due To Prior Abdominal Adhesions Case Report, Liubin Yang, Lydia Kao

Children’s Nutrition Research Center Staff Publications

Intestinal obstruction rarely occurs after uncomplicated vaginal deliveries. Here, we present a case of a multiparous woman with a history of prior appendectomy presenting with generalized, nonspecific abdominal pain that was out of proportion to exam findings. Initial abdominal X-ray was nonspecific, and subsequent computed tomography (CT) abdomen showed closed small bowel obstruction requiring surgical repair. We present a case of intestinal obstruction occurring within 24 hours of uncomplicated vaginal delivery with a risk factor of a prior appendectomy surgery and the use of CT abdomen and pelvis to expedite diagnose.

Institute of Emerging Health Professions Faculty Papers

Passive aerosol exposure to Δ9-tetrahydrocannabinol (THC) in laboratory animals results in faster onset of action and less extensive liver metabolism compared to most other administration routes and might thus provide an ecologically relevant model of human cannabis inhalation. Previous studies have, however, overlooked the possibility that rodents, as obligate nose breathers, may accumulate aerosolized THC in the nasal cavity, from where the drug might directly diffuse to the brain. To test this, we administered THC (ten 5-s puffs of 100 mg/mL of THC) to adolescent (31-day-old) Sprague-Dawley rats of both sexes. We used liquid chromatography/tandem mass spectrometry to quantify the …

The Role Of Superb Microvascular Imaging In Detecting Low-Grade Inflammation Among Adults And Those With Chronic Kidney Disease: A Preliminary Study, Alaaddi̇n Nayman, Nusret Seher, Mehmet Öztürk, Hali̇l Özer, Gülperi̇ Çeli̇k

Turkish Journal of Medical Sciences

Background/aim: Pathophysiologic changes associated with chronic inflammation occur with aging and more prominently in patients with chronic kidney disease (CKD), and an association between chronic inflammation and muscle wasting has been identified. The microcirculation is extremely sensitive to the inflammatory process and actively participates in it. In a healthy adult, angiogenesis is a strictly controlled and rare occurrence. However, aberrant angiogenesis and the development of new tiny blood vessels are known in chronic inflammatory diseases. Superb microvascular imaging (SMI) is a noninvasive technique that can evaluate tiny vessels with low blood flow and provide quantitative data. Our goal was to …

Diabetes mellitus (DM) is a leading cause of death and reduces life expectancy. Complications from diabetes have wreaked havoc not only on patients' quality of life, but also on the global burdens of public health and socioeconomic development. The most frequent complication among patients with diabetes mellitus is diabetic wounds, particularly diabetic foot ulcers because of the damage to sensory nerves and blood vessel issues brought on by elevated blood glucose levels. As a result, chronic wounds eventually develop and are prone to infection. In this study, several novel analytical devices for the detection of wound infections and the wound …

Mycobacterium Spp. Identification By Nanopore Technology, Samitanan Sunantawanit

Chulalongkorn University Theses and Dissertations (Chula ETD)

Tuberculosis is caused by infection with Mycobacterium tuberculosis (MTB). Although TB and non-tuberculous mycobacteria (NTM) infection exhibit similar symptoms, their treatments differ significantly. NTM strains need a specific drug regimen and some NTM strains are resistant to anti-TB drugs. Hence, mycobacterial identification is crucial. At present, the culture-based technique is the gold standard in mycobacterium detection, but it is time-consuming (3-6 weeks). Here, this study aimed to develop mycobacterial amplicon-based nanopore sequencing (Myco-ANS) assay for the differentiation of eight reference strains of mycobacteria, as well as to assess the diagnostic accuracy of Myco-ANS compared with reference line probe assay for …

Gardenia Jasminoides Fruit Extract Alleviates Non-Steroidal Anti-Inflammatory Drug–Induced Gastropathy In Rats, Rinrada Worapongpaiboon

Chulalongkorn University Theses and Dissertations (Chula ETD)

Non-steroidal anti-inflammatory drug (NSAID)-induced gastropathy is a health burden that requires effective treatment. Gardenia jasminoides fruit extract (GJE) protects the gastrointestinal tract by reducing inflammation with wide safety margins, but the underlying mechanisms are still indeterminate. Therefore, this thesis aimed to explore the effects of GJE pretreatment on NSAID-induced gastric injury in rats based on the hypothesis that GJE could attenuate the injury. Twenty-four male Sprague Dawley rats were assigned to 3 groups (n=8/group). The control group received a vehicle (7.5% NaHCO3). The NSAIDs group received indomethacin 200 mg/kg twice a day (4 hours apart) for 2 consecutive days. The …

The Antimicrobial Peptide Database Is 20 Years Old: Recent Developments And Future Directions, Guangshun Wang

Journal Articles: Pathology and Microbiology

In 2023, the Antimicrobial Peptide Database (currently available at https://aps.unmc.edu) is 20-years-old. The timeline for the APD expansion in peptide entries, classification methods, search functions, post-translational modifications, binding targets, and mechanisms of action of antimicrobial peptides (AMPs) has been summarized in our previous Protein Science paper. This article highlights new database additions and findings. To facilitate antimicrobial development to combat drug-resistant pathogens, the APD has been re-annotating the data for antibacterial activity (active, inactive, and uncertain), toxicity (hemolytic and nonhemolytic AMPs), and salt tolerance (salt sensitive and insensitive). Comparison of the respective desired and undesired AMP groups produces new knowledge …

Characterizing Cellular Injury And Inflammation With Aldob-/-Mouse Model Of Mafld, Andy Rashid

All Master's Theses

Metabolic-associated fatty liver disease (MAFLD) affects 1 in 3 people in the US and is a healthcare burden on the order of billions of dollars. MAFLD is characterized by pathological lipid accumulation in the liver, excess production of triglycerides and cholesterol, and export of LDL particles that raise serum lipid levels. These metabolic perturbations can lead to the development of liver fibrosis, chronic inflammation, and insulin resistance. Diagnosing MAFLD prior to fibrosis is crucial for successful intervention and prevention of advanced liver disease and other metabolic complications. Fructose-1Phospahte (F1P) accumulation from fructose overconsumption can drive hepatic lipogenesis and MAFLD progression. …

On The Origin And Evolution Of The Dual Oscillator Model Underlying The Photoperiodic Clockwork In The Suprachiasmatic Nucleus, Jennifer A. Evans, William J. Schwartz

Biomedical Sciences Faculty Research and Publications

Decades have now passed since Colin Pittendrigh first proposed a model of a circadian clock composed of two coupled oscillators, individually responsive to the rising and setting sun, as a flexible solution to the challenge of behavioral and physiological adaptation to the changing seasons. The elegance and predictive power of this postulation has stimulated laboratories around the world in searches to identify and localize such hypothesized evening and morning oscillators, or sets of oscillators, in insects, rodents, and humans, with experimental designs and approaches keeping pace over the years with technological advances in biology and neuroscience. Here, we recount the …

Developmental Patterning Of Peptide Transcription In The Central Circadian Clock In Both Sexes, Vania Carmona-Alcocer, Lindsey S. Brown, Aisha Anchan, Kayla E. Rohr, Jennifer A. Evans

Biomedical Sciences Faculty Research and Publications

Introduction: Neuropeptide signaling modulates the function of central clock neurons in the suprachiasmatic nucleus (SCN) during development and adulthood. Arginine vasopressin (AVP) and vasoactive intestinal peptide (VIP) are expressed early in SCN development, but the precise timing of transcriptional onset has been difficult to establish due to age-related changes in the rhythmic expression of each peptide.

Methods: To provide insight into spatial patterning of peptide transcription during SCN development, we used a transgenic approach to define the onset of Avp and Vip transcription. Avp-Cre or Vip-Cre males were crossed to Ai9^+/+ females, producing offspring in which the fluorescent protein …

Graduate Theses, Dissertations, and Problem Reports (ETD)

Excellent motor control skills are necessary to live a high-quality life. Activities such as walking, getting dressed, and feeding yourself may seem mundane, but injuries to the neuromuscular system can render these tasks difficult or even impossible to accomplish without assistance. Statistics indicate that well over 100 million people are affected by diseases or injuries, such as stroke, Parkinson’s Disease, Multiple Sclerosis, Cerebral Palsy, peripheral nerve injury, spinal cord injury, and amputation, that negatively impact their motor abilities. This wide array of injuries presents a challenge to the medical field as optimal treatment paradigms are often difficult to implement due …

Development And Characterization Of Monoclonal Antibodies Against Pseudomonas Aeruginosa, Jason Kang

Graduate Theses, Dissertations, and Problem Reports (ETD)

Antimicrobial resistance (AMR) has emerged as a global crisis, posing significant challenges to the treatment and management of infectious diseases. The escalating prevalence of antibiotic-resistant bacteria has made many antimicrobial therapies ineffective, necessitating the development of alternative strategies to combat microbial infections. The rise of multidrug-resistant pathogens, such as Pseudomonas aeruginosa and Serratia marcescens, further exacerbates this problem, as these pathogens exhibit high levels of resistance to multiple antibiotics and cause severe infections in vulnerable populations. In response to the need for alternative therapeutic approaches, monoclonal antibodies (mAbs) have emerged as promising candidates for combating AMR. In this work, we …

Longitudinal Oxygen Imaging In 3d (Bio)Printed Models, Ryan Curtis O'Connell

Graduate Theses, Dissertations, and Problem Reports (ETD)

Electron paramagnetic resonance (EPR), and its molecular imaging modality, is a powerful tool to noninvasively map various biological and chemical markers within objects of interest. Reliable data acquisition is a major impeding factor for longitudinal hands-off measurements. Measurements are especially challenging in biomedical applications, as live objects are not static. Frequent changes occur that require constant fine recalibration of the EPR detection system, called the resonator. To enable longitudinal imaging, a technology permitting automatic digital control of resonator coupling, tuning, and EPR data acquisition was developed. Automation was achieved through the utilization of a microcontroller and digital peripheral components such …

Glial Cell-Specific Contribution Of Pkr-Like Er Kinase (Perk) In Neuroinflammation And Behavior, Anirudhya Lahiri

Graduate Theses, Dissertations, and Problem Reports (ETD)

Neurological disorders such as multiple sclerosis (MS) are a major public health concern in the US, with no available therapeutic cure. Chronic neuroinflammation and aberrant proteostasis in the central nervous system (CNS) are the major hallmarks of neurological diseases. Endoplasmic Reticulum (ER) is a major cellular organelle involved in protein synthesis, folding and maturation of various secretory and transmembrane proteins. Pathophysiological stressors such as trauma and infection result in misfolded protein accumulation in the endoplasmic reticulum (ER) lumen, which results in ER stress. To regain proteostasis (protein homeostasis), cells activate the unfolded protein response (UPR). UPR is an evolutionarily conserved …

Influence Of Maternal Nano-Titanium Dioxide Inhalation Exposure On Cyclooxygenase Metabolites: Maternal Microvascular And Sexually Dimorphic Feto-Placental Outcomes., Julie Anne Griffith

Graduate Theses, Dissertations, and Problem Reports (ETD)

Nano-titanium dioxide (nano-TiO₂) is an engineered nanomaterial (ENM), which is widely utilized in diverse products like surface coatings, cosmetics, medical devices, and filters. Inhaled nano-TiO₂ has been demonstrated to induce pulmonary inflammation, impair microvascular function, and hinder generational reproductive endpoints. These outcomes indicate why it is important to explore gestation, as it requires timely vascular adaptations to support maternal and fetal health and development. Therefore, the central hypothesis of my dissertation is: maternal nano-TiO₂ inhalation exposure will impact maternal microvascular function and fetoplacental hemodynamics and function in a sexually dimorphic manner.

The first purpose of …

Beneficial Impacts Of Nod-Like Receptor X1(Nlrx1) Agonism In Lipopolysaccharide-Induced Inflammation, Mena Mansy

Graduate Theses, Dissertations, and Problem Reports (ETD)

Introduction: The regulation of inflammation at the cellular and molecular level is a crucial aspect of homeostasis that is often overlooked, and most treatment options are limited to antibiotics and symptom management drugs. The development of novel molecular-targeted therapy options downstream of pathogen recognition receptors will fulfill the unmet need for therapy to effectively regulate excessive inflammation. NLRX1 is a unique NOD-like receptor that is anti-inflammatory in nature; it has been shown to negatively regulate the NF-kB pathway and has been involved in the pathology of a plethora of inflammatory disorders. This makes NLRX1 an emerging therapeutic molecular target for …

Il-27 Negatively Impacts Immunity Developed Following Bcg Administration, Shelby D. Bradford

Graduate Theses, Dissertations, and Problem Reports (ETD)

Mycobacterium tuberculosis (Mtb) is the causative agent of tuberculosis (TB), a predominantly respiratory pathogen responsible for over ten million infections and one million deaths last year. Despite it being a primary objective of the World Health Organization (WHO) for several decades to irradicate TB, progress toward this objective has fallen short of the 2020 target to end TB by 2035. Meeting this goal will require advancements in diagnostic tools, education, healthcare access, and treatments and preventatives. Regarding prevention, the primary tool for this strategy is through vaccination. Currently, the only licensed vaccine for protection against TB is the century old …

Voice Quality Assessment In Cases Of Vocal Fold Gaps After Single Growth Factor Injection, Amr Roushdyel Badrawy, Asmaa Abdel Hamid, Israa Eltaweel, Azza Abdel Aziz Azzam

Journal of Medicine in Scientific Research

In severe vocal fold (VF) lesions, deposits of disorganized, thick collagen bundles and little hyaluronic acid (HA) are deposited in the superficial layer of lamina propria (SLP). These changes lead to severe dysphonia and aspiration, which could be complicated by fatal pneumonia. Unfortunately, no specific treatment has been recognized due to unpredictable VF regeneration. Current progress in regenerative medicine has allowed the development of tissue engineering techniques using cells, scaffolds, and growth factors (GFs). Extrinsic GFs application could help in the induction of the regenerative process. The work aims to assess the voice quality after a single GF injection of …

Knockout Of Endospanin 1 Via Crispr In Zebrafish, Danio Rerio, Jared Kittinger

Williams Honors College, Honors Research Projects

I made endospanin 1 knockout (KO) zebrafish to examine its effects on lipid and bone metabolism. Endospanin 1, or leptin receptor overlapping transcript (leprot), is a cytosolic protein linked to the protein hormone leptin that influences the trafficking of leptin receptors to the plasma membrane of cells. Genes for endospanin and tyrosinase (a pigmentation enzyme) were targeted via a microinjection of guide RNAs and CRISPR Cas9 into zebrafish embryos at 2-4 cell stages. I was able to disrupt the endospanin 1 gene (based upon the disruption of tyrosinase), but very few mutant zebrafish fully developed into adults. Only low KO …

Journal Articles: Biochemistry & Molecular Biology

BACKGROUND: Small cell lung cancer (SCLC) is an aggressive lung cancer subtype that is associated with high recurrence and poor prognosis. Due to lack of potential drug targets, SCLC patients have few therapeutic options. MicroRNAs (miRNAs) provide an interesting repertoire of therapeutic molecules; however, the identification of miRNAs regulating SCLC growth and metastasis and their precise regulatory mechanisms are not well understood.

METHODS: To identify novel miRNAs regulating SCLC, we performed miRNA-sequencing from donor/patient serum samples and analyzed the bulk RNA-sequencing data from the tumors of SCLC patients. Further, we developed a nanotechnology-based, highly sensitive method to detect microRNA-1 (miR-1, …

Poor visualization of polyps can limit colorectal cancer screening. Fluorescent antibodies to mucin5AC (MUC5AC), a glycoprotein upregulated in adenomas and colorectal cancer, could improve screening colonoscopy polyp detection rate. Adenomatous polyposis coli flox mice with a Cdx2-Cre transgene (CPC-APC) develop colonic polyps that contain both dysplastic and malignant tissue. Mice received MUC5AC-IR800 or IRdye800 as a control IV and were sacrificed after 48 h for near-infrared imaging of their colons. A polyp-to-background ratio (PBR) was calculated for each polyp by dividing the mean fluorescence intensity of the polyp by the mean fluorescence intensity of the background tissue. The mean 25 …

Gpcrs And Fibroblast Heterogeneity In Fibroblast-Associated Diseases, Nidhi V. Dwivedi, Souvik Datta, Karim El-Kersh, Ruxana Sadikot Md, Mrcp, Apar Kishor Ganti, Surinder K. Batra, Maneesh Jain

Journal Articles: Biochemistry & Molecular Biology

G protein-coupled receptors (GPCRs) are the largest and most diverse class of signaling receptors. GPCRs regulate many functions in the human body and have earned the title of "most targeted receptors". About one-third of the commercially available drugs for various diseases target the GPCRs. Fibroblasts lay the architectural skeleton of the body, and play a key role in supporting the growth, maintenance, and repair of almost all tissues by responding to the cellular cues via diverse and intricate GPCR signaling pathways. This review discusses the dynamic architecture of the GPCRs and their intertwined signaling in pathological conditions such as idiopathic …

Roles Unveiled For Membrane-Associated Mucins At The Ocular Surface Using A Muc4 Knockout Mouse Model, Rafael Martinez-Carrasco, Satyanarayan Rachagani, Surinder K. Batra, Pablo Argüeso, M Elizabeth Fini

Journal Articles: Biochemistry & Molecular Biology

Membrane-associated mucins (MAMs) are proposed to play critical roles at the ocular surface; however, in vivo evidence has been lacking. Here we investigate these roles by phenotyping of a Muc4 KO mouse. Histochemical analysis for expression of the beta-galactosidase transgene replacing Muc4 revealed a spiraling ribbon pattern across the corneal epithelium, consistent with centripetal cell migration from the limbus. Depletion of Muc4 compromised transcellular barrier function, as evidenced by an increase in rose bengal staining. In addition, the corneal surface was less smooth, consistent with disruption of tear film stability. While surface cells presented with well-developed microprojections, an increase in …

Dietary Whey Protein Increases Brain Leukocytes In Mice Regardless Of Their Hypersensitivity Status, Dilini Ekanayake

Biomedical Sciences Posters and Presentations

Cow’s milk allergy (CMA) often manifests as milder reactions and may be linked to neurological problems. Previously, we demonstrated that C57BL/6J mice sensitized to a bovine whey allergen, β-lactoglobulin (BLG, Bos d 5), moderately increased BLG-specific IgE levels and exhibited behavioral changes without severe allergic reactions. When these non-anaphylactic CMA mice were placed on a whey-protein (WP)-containing diet for 2 weeks to simulate continuous dairy consumption, we found neuropathology indicative of neuroinflammation and cortical demyelination. Since immune cells migrate to the central nervous system (CNS) and promote neuroinflammation in demyelinating conditions such as multiple sclerosis, we hypothesized that the number …

Histamine H3 Receptor Antagonism Mitigates Food-Hypersensitivity-Associated Depressive Behavior And Neuropathology In A Mouse Model Of Cow’S Milk Allergy, Danielle Germundson-Hermanson

Biomedical Sciences Posters and Presentations

Background Histamine is best known for causing allergy symptoms, but it also regulates blood-brain barrier permeability1 and oligodendrocyte differentiation2. Thus, brain histamine levels are tightly controlled.

Previous Findings We demonstrated that histamine and histamine H3 receptor (H3R) levels were elevated in a mouse model of cow’s milk allergy (CMA) in association with intracranial mast cell activation, depression-like behaviors, and cortical demyelination3,4.

Gaps in Knowledge In humans, food allergies are often associated with neuropsychiatric disorders5-7, but the involvement of allergy induced histamine in triggering behavioral changes is unclear.

Hypothesis Repeated allergen consumption can lead to central histaminergic dysfunction through H3R, ultimately …

Continuous Consumption Of Whey Protein Maintains Neuroinflammation In A Mouse Model Of Asymptomatic Cow’S Milk Allergy, Geetika Verma

Biomedical Sciences Posters and Presentations

Using a mouse model of cow’s milk allergy (CMA), we previously showed that C57BL/6J mice sensitized to a bovine whey allergen, β-lactoglobulin (BLG), exhibited anxiety/depression-like behavior and neuroinflammation in the absence of overt anaphylaxis upon allergen exposure
