Exploration Of The Association Between Muscle Volume And Bone Geometry Reveals Surprising Relationship At The Genetic Level, Prakrit Subba
Exploration Of The Association Between Muscle Volume And Bone Geometry Reveals Surprising Relationship At The Genetic Level, Prakrit Subba
Masters Theses
The evolution of jaws in cichlid fishes of the East African Great Lakes is a textbook example of adaptive radiation in vertebrates. Karl Liem postulated that this adaptive radiation has been possible due to the functional decoupling of two cichlid functional units – the pharyngeal jaw (PJ) and the oral jaw (OJ). This functional decoupling of the jaws has enabled the OJ to be relieved of its dual role of prey capturing and processing and has allowed the PJ to take on the role of prey processing. As a result, African cichlids have adapted the morphology of their functional units …

Maternal immune activation (MIA) in response to infection during pregnancy has been linked through various epidemiological and preclinical studies to an increased risk of neurodevelopmental disorders such as autism spectrum disorder (ASD) and schizophrenia in exposed offspring. Sensory filtering disruptions occur in both of these disorders and are typically measured using the acoustic startle response in both humans and rodents. Our study focuses on characterizing the baseline reactivity, habituation and prepulse inhibition (PPI) of the acoustic startle response following exposure to MIA. We induced MIA using polyinosinic: polycytidylic acid (poly I:C) at gestational day (GD) 9.5 or 14.5, and we …

© 2020 The Author(s). Background: Intercellular exchange between the oocyte and its surrounding cells within the follicular environment is critical for oocyte maturation and subsequent development. In vertebrates this exchange is facilitated through gap junctions formed by connexin membrane proteins. Another family of membrane proteins called pannexins are able to form single membrane channels that allow cellular exchanges with the extracellular environment. The most ubiquitously expressed and studied member, pannexin 1 (PANX1), has yet to be described thoroughly in female reproductive tissues or functionally studied during oocyte maturation. Here, we look into the expression of pannexin 1 in bovine cumulus-oocyte …

Pharmacy Faculty Articles and Research
Ethoxyresorufin (ER)-O-deethylation (EROD) activity has been widely used to assess cytochrome P450 1A (CYP1A) activity. The kinetics of CYP1A activity have been well characterized in the liver microsomes. However, studies in kidney microsomes are limited due to the much lower EROD activity in this organ. Here, we developed and validated a sensitive UPLC-MS/MS assay for the characterization of the EROD activity in the rat kidney microsomes. In a 50 µL reaction mixture, rat kidney microsomes (0.25 mg/mL) were incubated with ER (0.1–5 µM) and NADPH (1 mM) for 10 min. Acidic solvents, such as trichloroacetic acid or formic …

Copyright © 2020 the American Physiological Society Pannexin 1 (PANX1) is a ubiquitously expressed, channel-forming protein found in a number of tissues throughout the body (e.g., lung, vasculature, liver, central nervous system, immune system) that is important in many key physiological and immune responses (18, 55). PANX1 channels passively flux ATP (predominantly), multiple metabolites, and likely other small anions (37, 39). PANX1 channels regulate inflammation and host responses to several pathogens, including viruses (36, 42, 53). While there is currently no evidence suggesting novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and PANX1 directly interact, there is an urgent need …

Microglia And Fractalkine Involvement In Shaping Multimodal Midbrain Circuitry, Cooper A. Brett
Masters Theses, 2020-current
Microglial cells (MGCs) are highly dynamic and have been implicated in shaping discrete neural maps in several systems. MGCs respond to numerous cues in their microenvironment, including a neuronally-expressed chemokine, CX3CL1 (fractalkine). The present study examines microglial and CX3CL1 patterns with regard to the emerging modular-extramodular framework within the lateral cortex of the inferior colliculus (LCIC). The LCIC is a shell region of the auditory midbrain where discrete compartments receive modality-specific connections, whereby somatosensory inputs terminate within modules and auditory inputs target surrounding extramodular zones. A reliable modular marker, glutamic acid decarboxylase (GAD), enables visualization of emerging modular domains in …

The Effect Of Hypoxia On Brain Cell Proliferation In Weakly Electric Fish, Petrocephalus Degeni, Kaitlin Klovdahl
Senior Theses and Projects
Oxygen levels tend to remain at a steady state concentration in the Earth’s atmosphere, yet in some bodies of water, they can fluctuate and decrease drastically. Many organisms that inhabit the swamps, lakes, streams, and parts of the ocean where this occurs have evolved adaptations to manage this environmental uncertainty and continue normal oxygen consumption. The Lwamunda swamp in Uganda is chronically hypoxic, yet it is home to many species, including the electric fish Petrocephalus degeni. P. degeni are unusual by nature of their immense brain, and the Lwamunda swamp appears ill-suited for maintaining this large, metabolically active organ. To …

Autism spectrum disorders (ASD) are complex neurodevelopmental disorders that are caused by genetic and/or environmental impacts, often probably by the interaction of both. They are characterised by deficits in social communication and interaction and by restricted and repetitive behaviours and interests from early childhood on, causing significant impairment. While it is clear that no animal model captures the full complexity of ASD in humans, genetic models are extremely useful for studying specific symptoms associated with ASD and the underlying cellular and molecular mechanisms. In this review we summarize the behavioral paradigms used in rodents to model ASD symptoms as they …

Distal Urogenital Anatomy Of Male Prairie Racerunners, Aspidoscelis Sexlineatus Viridis (Reptilia: Sauria: Teiidae), Stanley E. Trauth
Journal of the Arkansas Academy of Science
I examined histologically the distal urogenital anatomy in male Prairie Racerunners (Aspidoscelis sexlineatus viridis) from a small seasonal sample of individuals collected in Arkansas in order to provide additional information regarding squamate urogenital anatomy. Specifically, I focused on the basic anatomy and positioning of posterior ducts and associated structures in this teiid lizard. The anatomical structures included the ductus deferens, ampulla ductus deferens, ampulla urogenital papilla (Aup), ureter, inner core tissue mass, urodaeum, and the urogenital papilla. The two Aup, which are small complimentary blind pouches representing the terminal repositories for products released by urogenital ducts, are striking …
