Background and Objective

Immune checkpoint inhibitors (ICIs) have been widely applied and studied in the treatment of gastrointestinal (GI) cancers, and have achieved good results. However, in clinical practice, it has been observed that only some patients respond well to ICIs, and some patients may experience various degrees of adverse reactions during the treatment. Timely evaluation of the potential therapeutic effects and adverse reactions of ICIs for patients has important clinical significance. This review aimed to summarize recent progress regarding efficacy-associated biomarkers for ICIs in GI cancer.

Methods

The literature on ICI treatment in GI cancers was searched in the …

Piriformis Syndrome With A Variant Presentation, Roberto Chuapoco, Ryan E. Linford

Annual Research Symposium

Piriformis syndrome has long been a diagnostic quandary due to its tendency to present as other nerve-related conditions. Piriformis syndrome is commonly caused by entrapment of the sciatic nerve as it travels through the greater sciatic foramen due to hypertrophy of the piriformis muscle. However, its constellation of symptoms, including radiating pain down the thigh, can easily be mistaken for lumbosacral radiculopathy. This case report aims to address the misdiagnosis of piriformis syndrome which has prolonged pain for many patients and increased the cost of medical care. It demonstrates a 76-year-old female with a confounding presentation of piriformis syndrome: buttock …

Faculty, Staff and Student Publications

The gate-type carbon nanotubes cathodes exhibit advantages in long-term stable emission owing to the uniformity of electrical field on the carbon nanotubes, but the gate inevitably reduces the transmittance of electron beam, posing challenges for system stabilities. In this work, we introduce electron beam focusing technique using the self-charging SiN_x/Au/Si gate. The potential of SiN_x is measured to be approximately −60 V quickly after the cathode turning on, the negative potential can be maintained as the emission goes on. The charged surface generates rebounding electrostatic forces on the following electrons, significantly focusing the electron beam on the …

Sex-Specific Negative Affect-Like Behaviour And Parabrachial Nucleus Activation Induced By Bnst Stimulation In Adult Mice With Adolescent Alcohol History, Lucas Albrechet-Souza, Chelsea R. Kasten, Natalia B. Bertagna, Tiffany A. Wills

School of Medicine Faculty Publications

Adolescent alcohol use is a strong predictor for the subsequent development of alcohol use disorders later in life. Additionally, adolescence is a critical period for the onset of affective disorders, which can contribute to problematic drinking behaviours and relapse, particularly in females. Previous studies from our laboratory have shown that exposure to adolescent intermittent ethanol (AIE) vapour alters glutamatergic transmission in the bed nucleus of the stria terminalis (BNST) and, when combined with adult stress, elicits sex-specific changes in glutamatergic plasticity and negative affect-like behaviours in mice. Building on these findings, the current work investigated whether BNST stimulation could substitute …

Faculty, Staff and Student Publications

Background

Microglia-mediated neuroinflammation in Alzheimer’s disease (AD) is not only a response to pathophysiological events, but also plays a causative role in neurodegeneration. Cytoplasmic cysteinyl-tRNA synthetase (CARS) is considered to be a stimulant for immune responses to diseases; however, it remains unknown whether CARS is involved in the pathogenesis of AD.

Methods

Postmortem human temporal cortical tissues at different Braak stages and AD patient-derived serum samples were used to investigate the changes of CARS levels in AD by immunocytochemical staining, real-time PCR, western blotting and ELISA. After that, C57BL/6J and APP/PS1 transgenic mice and BV-2 cell line were used to …

Rasquinha, Kiruthiga Mone, Chandirasegaran Massilamany, Ninaad Lasrado, Channabasavaiah B. Gurumurthy, Raymond A Sobel, Jay Reddy

Journal Articles: Genetics, Cell Biology & Anatomy

Myocarditis is one of the major causes of heart failure in children and young adults and can lead to dilated cardiomyopathy. Lymphocytic myocarditis could result from autoreactive CD4⁺ and CD8⁺ T cells, but defining antigen specificity in disease pathogenesis is challenging. To address this issue, we generated T cell receptor (TCR) transgenic (Tg) C57BL/6J mice specific to cardiac myosin heavy chain (Myhc)-α 334-352 and found that Myhc-α-specific TCRs were expressed in both CD4⁺ and CD8⁺ T cells. To investigate if the phenotype is more pronounced in a myocarditis-susceptible genetic background, we backcrossed with A/J mice. At …

Journal Articles: Genetics, Cell Biology & Anatomy

BACKGROUND: Transgenic (Tg) mice are widely used in biomedical research, and they are typically generated by injecting transgenic DNA cassettes into pronuclei of one-cell stage zygotes. Such animals often show unreliable expression of the transgenic DNA, one of the major reasons for which is random insertion of the transgenes. We previously developed a method called "pronuclear injection-based targeted transgenesis" (PITT), in which DNA constructs are directed to insert at pre-designated genomic loci. PITT was achieved by pre-installing so called landing pad sequences (such as heterotypic LoxP sites or attP sites) to create seed mice and then injecting Cre recombinase or …

Ultrasound-Guided Erector Spinae Plane Block: An Objective Structured Clinical Examination For First-Year Anesthesia Providers, Andrew Edwards, Jonathan Mardis

Doctoral Projects

The use of ultrasound-guided regional anesthesia (UGRA) in anesthetic practice is an invaluable tool for anesthesia providers to implement into their daily practice. One of these regional techniques is the erector spinae plane block (ESPB) which has anesthetic implications in numerous surgical procedures including cervical spine, thoracolumbar spine, thoracic wall, and chest wall procedures. Because of the novelty of this regional anesthetic technique, it is important to educate first-year anesthesia providers about the implications, skillset, and complications of the ESPB.

To bridge the gap between didactic knowledge and clinical practice in first-year anesthesia providers, an objective structured clinical examination (OSCE) …

Considerable progress has been made in studying the receptive fields of the most common primate retinal ganglion cell (RGC) types, such as parasol RGCs. Much less is known about the rarer primate RGC types and the circuitry that gives rise to noncanonical receptive field structures. The goal of this study was to analyze synaptic inputs to smooth monostratified RGCs to determine the origins of their complex spatial receptive fields, which contain isolated regions of high sensitivity called "hotspots." Interestingly, smooth monostratified RGCs co-stratify with the well-studied parasol RGCs and are thus constrained to receiving input from bipolar and amacrine cells …

Addressing Healthcare Disparities Faced By Aging Down Syndrome Populations, Rhea Mistry

Pitzer Senior Theses

Down syndrome (DS) is a chromosomal genetic condition that impacts the development of the body and brain. The life expectancy of individuals with DS has drastically improved over the decades, increasing from 9 years in 1929 to 25 years in 1983 and further reaching 60 years by 2002. Individuals with DS face a variety of prominent co-occurring health conditions that are subject to change over time, including cognitive, visual, and hearing impairments, sleep apnea, cardiovascular defects, Down syndrome regression disorder, and dementia. Despite this increase in life span, DS is still most familiar to pediatric care providers, resulting in healthcare …

Theses and Dissertations--Music

Transitioning from one gender to another can be an arduous and emotionally charged experience, accompanied by many physical and mental transformations. The journey of self-discovery and vocal explorations is both unique and deeply personal. Modifications that emerge in an individual's vocal characteristics have a profound influence on their capacity to communicate and express themselves.

Transgender vocal students and professional singers must navigate the delicate balance between their vocal and gender identities while considering the possible risks of Gender Affirming Hormone Therapy. Though these therapies may significantly alter one's appearance and overall well-being, they are also capable of causing notable declines …

Enhancing Associative Learning In Rats With A Computationally Designed Training Protocol, Xu O Zhang, Yili Zhang, Claire E Cho, Douglas S Engelke, Paul Smolen, John H Byrne, Fabricio H Do-Monte

Faculty, Staff and Student Publications

Background

Learning requires the activation of protein kinases with distinct temporal dynamics. In Aplysia, nonassociative learning can be enhanced by a computationally designed learning protocol with intertrial intervals (ITIs) that maximize the interaction between fast-activated PKA (protein kinase A) and slow-activated ERK (extracellular signal-regulated kinase). Whether a similar strategy can enhance associative learning in mammals is unknown.

Methods

We simulated 1000 training protocols with varying ITIs to predict an optimal protocol based on empirical data for PKA and ERK dynamics in rat hippocampus. Adult male rats received the optimal protocol or control protocols in auditory fear conditioning and fear …

Mild traumatic brain injury (mTBI) accounts for 70-90% of all TBI cases. Lipid metabolites have important roles in plasma membrane biogenesis, function, and cell signaling. As TBI can compromise plasma membrane integrity and alter brain cell function, we sought to identify circulating phospholipid alterations after mTBI, and determine if these changes were associated with clinical outcomes. Patients with mTBI (Glasgow Coma Score [GCS] ≥13 and loss of consciousness <30 >min) were recruited. A total of 84 mTBI subjects were enrolled after admission to a level I trauma center, with the majority having evidence of traumatic intracranial hemorrhage on brain computed tomography …

Structures Of Channelrhodopsin Paralogs In Peptidiscs Explain Their Contrasting K+ And Na+ Selectivities, Shu Kikuta, Shin Nagayama, Sanae Hasegawa-Ishii

Faculty, Staff and Student Publications

The olfactory epithelium (OE) is directly exposed to environmental agents entering the nasal cavity, leaving OSNs prone to injury and degeneration. The causes of olfactory dysfunction are diverse and include head trauma, neurodegenerative diseases, and aging, but the main causes are chronic rhinosinusitis (CRS) and viral infections. In CRS and viral infections, reduced airflow due to local inflammation, inflammatory cytokine production, release of degranulated proteins from eosinophils, and cell injury lead to decreased olfactory function. It is well known that injury-induced loss of mature OSNs in the adult OE causes massive regeneration of new OSNs within a few months through …

Role Of A Pdlim5:Palmd Complex In Directing Dendrite Morphology, Yogesh Srivastava, Maxsam Donta, Lydia L Mireles, Adriana Paulucci-Holthauzen, M Neal Waxham, Pierre D Mccrea

Faculty, Staff and Student Publications

Neuronal connectivity is regulated during normal brain development with the arrangement of spines and synapses being dependent on the morphology of dendrites. Further, in multiple neurodevelopmental and aging disorders, disruptions of dendrite formation or shaping is associated with atypical neuronal connectivity. We showed previously that Pdlim5 binds delta-catenin and promotes dendrite branching. We report here that Pdlim5 interacts with PalmD, a protein previously suggested by others to interact with the cytoskeleton (e.g.,

Anesthetized Animal Experiments For Neuroscience Research, Shin Nagayama, Sanae Hasegawa-Ishii, Shu Kikuta

Faculty, Staff and Student Publications

Brain research has progressed with anesthetized animal experiments for a long time. Recent progress in research techniques allows us to measure neuronal activity in awake animals combined with behavioral tasks. The trends became more prominent in the last decade. This new research style triggers the paradigm shift in the research of brain science, and new insights into brain function have been revealed. It is reasonable to consider that awake animal experiments are more ideal for understanding naturalistic brain function than anesthetized ones. However, the anesthetized animal experiment still has advantages in some experiments. To take advantage of the anesthetized animal …

Validating Osteological Correlates For The Hepatic Piston In The American Alligator (Alligator Mississippiensis), Clinton A. Grand Pre, William Thielicke, Raul E. Diaz, Brandon P. Hedrick, Ruth M. Elsey, Emma R. Schachner

School of Graduate Studies Faculty Publications

Unlike the majority of sauropsids, which breathe primarily through costal and abdominal muscle contractions, extant crocodilians have evolved the hepatic piston pump, a unique additional ventilatory mechanism powered by the diaphragmaticus muscle. This muscle originates from the bony pelvis, wrapping around the abdominal viscera, extending cranially to the liver. The liver then attaches to the caudal margin of the lungs, resulting in a sub-fusiform morphology for the entire ‘‘pulmo-hepatic-diaphragmatic’’ structure. When the diaphragmaticus muscle contracts during inspiration, the liver is pulled caudally, lowering pressure in the thoracolumbar cavity, and inflating the lungs. It has been established that the hepatic piston …

Using Plastinated Cadaveric Models For Anatomical Study Of Dorsalis Pedis Artery And Its Variation, Steven Bolton, Ifunanya Monube, Hooman Tabatabai-Mir

School of Podiatric Medicine - Student Research

The dorsalis pedis artery is a main artery of the dorsum of the foot. It directly arises from the anterior tibial artery and travels distally to the base of the 1st metatarsal. Its main function includes supplying oxygenated blood to the dorsal surface of the foot. A weak dorsalis pedis pulse is an indication of underlying circulation issue, such as peripheral vascular disease. Anatomical variations of the artery are not uncommon, including the total absence of the artery. Branching variations occur in approximately 10% of the population. Knowledge of these variations is critical for surgeons to prevent surgical complications

Faculty, Staff and Student Publications

Methylphenidate (MPD), known as Ritalin, is a psychostimulant used to treat children, adults, and the elderly. MPD exerts its effects through increasing concentrations of dopamine (DA), norepinephrine (NE), and serotonin (5-HT) in the synaptic cleft. Concomitant behavioral and neuronal recording from the ventral tegmental area (VTA), locus coeruleus (LC), and from the dorsal raphe (DR) nucleus, which are the sources of DA, NE, and 5-HT to the mesocorticolimbic circuit, were investigated following acute and repetitive (chronic) saline, 0.6, 2.5, or 10.0 mg/kg MPD. Animals received daily saline or MPD administration on experimental days 1 to 6 (ED1–6), followed by a …

Voltage- And Calcium-Gated Membrane Currents Tune The Plateau Potential Properties Of Multiple Neuron Types, Curtis L Neveu, Paul Smolen, Douglas A Baxter, John H Byrne

Faculty, Staff and Student Publications

Many neurons exhibit regular firing that is limited to the duration and intensity of depolarizing stimuli. However, some neurons exhibit all-or-nothing plateau potentials that, once elicited, can lead to prolonged activity that is independent of stimulus intensity or duration. To better understand this diversity of information processing, we compared the voltage-gated and Ca²⁺-gated currents of three identified neurons from hermaphroditic Aplysia californica. Two of these neurons, B51 and B64, generated plateau potentials and a third neuron, B8, exhibited regular firing and was incapable of generating a plateau potential. With the exception of the Ca²⁺-gated potassium …
