Characterization And Localization Of Antigens For Serodiagnosis Of Human Paragonimiasis, Kurt C Curtis, Kerstin Fischer, Young-Jun Choi, Makedonka Mitreva, Gary J Weil, Peter U Fischer

2020-Current year OA Pubs

Paragonimiasis is a foodborne trematode infection that affects 23 million people, mainly in Asia. Lung fluke infections lead frequently to chronic cough with fever and hemoptysis, and are often confused with lung cancer or tuberculosis. Paragonimiasis can be efficiently treated with praziquantel, but diagnosis is often delayed, and patients are frequently treated for other conditions. To improve diagnosis, we selected five Paragonimus kellicotti proteins based on transcriptional abundance, recognition by patient sera, and conservation among trematodes and expressed them as His-fusion proteins in Escherichia coli. Sequences for these proteins have 76-99% identity with amino acid sequences for orthologs in the …

Evidence Of Mitochondrial Dysfunction In Bacterial Chondronecrosis With Osteomyelitis–Affected Broilers, Alison Ferver, Elizabeth S. Greene, Robert F. Wideman Jr., Sami Dridi

Poultry Science Faculty Publications and Presentations

A leading cause of lameness in modern broilers is bacterial chondronecrosis with osteomyelitis (BCO). While it is known that the components of BCO are bacterial infection, necrosis, and inflammation, the mechanism behind BCO etiology is not yet fully understood. In numerous species, including chicken, mitochondrial dysfunction has been shown to have a role in the pathogenicity of numerous diseases. The mitochondria is a known target for intracellular bacterial infections, similar to that of common causative agents in BCO, as well as a known regulator of cellular metabolism, stress response, and certain types of cell death. This study aimed to determine …

Predictive Effects Of Physician Assistant Students' Pre-Admission Direct Patient Contact Hours On Performance In Supervised Clinical Practice Experiences, Gerald Robert Weniger

Doctoral Dissertations and Projects

The demand for physician assistants (PAs) is predicted to rise because of the growing shortage of physicians. PA educational programs are tasked with producing graduates who are skilled within six domains of competency: 1) medical knowledge, 2) professionalism, 3) interpersonal and communication skills, 4) patient care, 5) practice-based learning and improvement, and 6) systems-based practice. The Physician Assistant National Certifying Exam only assesses two of the six competencies: medical knowledge and professionalism. Without much time in a curriculum to teach the ‘softer skills’ like communication and interpersonal skills, many PA programs require pre-admission patient contact experience in order to at …

Cyclic Nucleotide Selectivity Of Protein Kinase G Isozymes, Choel Kim, Rajesh Sharma

Faculty, Staff and Students Publications

The intrinsic activity of the C-terminal catalytic (C) domain of cyclic guanosine monophosphate (cGMP)-dependent protein kinases (PKG) is inhibited by interactions with the N-terminal regulatory (R) domain. Selective binding of cGMP to cyclic nucleotide binding (CNB) domains within the R-domain disrupts the inhibitory R-C interaction, leading to the release and activation of the C-domain. Affinity measurements of mammalian and plasmodium PKG CNB domains reveal different degrees of cyclic nucleotide affinity and selectivity; the CNB domains adjacent to the C-domain are more cGMP selective and therefore critical for cGMP-dependent activation. Crystal structures of isolated CNB domains in the presence and absence …

Ramírez-Correa

School of Medicine Publications

Familial adenomatous polyposis (FAP) is an autosomal-dominant condition characterized by the presence of multiple colorectal adenomas, caused by germline variants in the adenomatous polyposis coli (APC) gene. More than 300 germline variants have been characterized. The detection of novel variants is important to understand the mechanisms of pathophysiology. We identified a novel pathogenic germline variant using next-generation sequencing (NGS) in a proband patient. The variant is a complex rearrangement (c.422+1123_532-577 del ins 423-1933_423-1687 inv) that generates a complete deletion of exon 5 of the APC gene. To study the variant in other family members, we designed an endpoint PCR method …

2020-Current year OA Pubs

We currently find ourselves in the midst of a global coronavirus disease 2019 (COVID-19) pandemic, caused by the highly infectious novel coronavirus, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Here, we discuss aspects of SARS-CoV-2 biology and pathology and how these might interact with the circadian clock of the host. We further focus on the severe manifestation of the illness, leading to hospitalization in an intensive care unit. The most common severe complications of COVID-19 relate to clock-regulated human physiology. We speculate on how the pandemic might be used to gain insights on the circadian clock but, more importantly, on …

Decoding Visual Information From High-Density Diffuse Optical Tomography Neuroimaging Data, Kalyan Tripathy, Zachary E Markow, Andrew K Fishell, Arefeh Sherafati, Tracy M Burns-Yocum, Mariel L Schroeder, Alexandra M Svoboda, Adam T Eggebrecht, Mark A Anastasio, Bradley L Schlaggar, Joseph P Culver

2020-Current year OA Pubs

BACKGROUND: Neural decoding could be useful in many ways, from serving as a neuroscience research tool to providing a means of augmented communication for patients with neurological conditions. However, applications of decoding are currently constrained by the limitations of traditional neuroimaging modalities. Electrocorticography requires invasive neurosurgery, magnetic resonance imaging (MRI) is too cumbersome for uses like daily communication, and alternatives like functional near-infrared spectroscopy (fNIRS) offer poor image quality. High-density diffuse optical tomography (HD-DOT) is an emerging modality that uses denser optode arrays than fNIRS to combine logistical advantages of optical neuroimaging with enhanced image quality. Despite the resulting promise …

School of Medicine Publications

Sea turtle populations are under threat from an epizootic tumor disease (animal epidemic) known as fibropapillomatosis. Fibropapillomatosis continues to spread geographically, with prevalence of the disease also growing at many longer-affected sites globally. However, we do not yet understand the precise environmental, mutational and viral events driving fibropapillomatosis tumor formation and progression.

Here we perform transcriptomic and immunohistochemical profiling of five fibropapillomatosis tumor types: external new, established and postsurgical regrowth tumors, and internal lung and kidney tumors. We reveal that internal tumors are molecularly distinct from the more common external tumors. However, they have a small number of conserved potentially …

Intestinal Stem Cell-Derived Enteroids From Morbidly Obese Patients Preserve Obesity-Related Phenotypes: Elevated Glucose Absorption And Gluconeogenesis, Nesrin M Hasan, Kelli F Johnson, Jianyi Yin, Nicholas W Baetz, Lea Fayad, Vadim Sherman, Sarah E Blutt, Mary K Estes, Vivek Kumbhari, Nicholas C Zachos, Olga Kovbasnjuk

Faculty, Staff and Students Publications

OBJECTIVE: The mechanisms behind the efficacy of bariatric surgery (BS) for treating obesity and type 2 diabetes, particularly with respect to the influence of the small bowel, remain poorly understood. In vitro and animal models are suboptimal with respect to their ability to replicate the human intestinal epithelium under conditions induced by obesity. Human enteroids have the potential to accelerate the development of less invasive anti-obesity therapeutics if they can recapitulate the pathophysiology of obesity. Our aim was to determine whether adult stem cell-derived enteroids preserve obesity-characteristic patient-specific abnormalities in carbohydrate absorption and metabolism.

METHODS: We established 24 enteroid lines …

The History & Status Of The Impact Act, Lisa M. Grabert

College of Nursing Faculty Research and Publications

The ability to effectively study and compare Medicare patients—and the cost and outcomes associated with their care—has long been, and continues to be limited, by the lack of readily comparable, patient-level, clinical data. This is due primarily to Medicare’s reliance and use of historically-developed, and limited administrative data—data derived from traditional insurance claims records, not patient treatment records. Critics of this situation have long called for the development of more comprehensive patient-level and clinically focused data, particularly in support of increasing efforts to compare and promote higher quality of care in the system.

Calls to develop more comprehensive patient outcome …

Faculty, Staff and Students Publications

Peripheral artery disease (PAD) is associated with impaired lower extremity function. We hypothesized that contrast-enhanced magnetic resonance imaging (CE-MRI) based arterial signal enhancement (SE) measures are associated with markers of PAD. A total of 66 participants were enrolled, 10 were excluded due to incomplete data, resulting in 56 participants for the final analyses (36 PAD, 20 matched controls). MR imaging was performed postreactive hyperemia using bilateral thigh blood-pressure cuffs. First pass-perfusion images were acquired at the mid-calf region with a high-resolution saturation recovery gradient echo pulse sequence, and arterial SE was measured for the lower extremity arteries. As expected, peak …

The Gut Microbiome Contributes To Blood-Brain Barrier Disruption In Spontaneously Hypertensive Stroke Prone Rats, James W Nelson, Sharon C Phillips, Bhanu P Ganesh, Joseph F Petrosino, David J Durgan, Robert M Bryan

Faculty, Staff and Students Publications

In recent years, it has become apparent that the gut microbiome can influence the functioning and pathological states of organs and systems throughout the body. In this study, we tested the hypothesis that the gut microbiome has a major role in the disruption of the blood-brain barrier (BBB) in the spontaneously hypertensive stroke prone rats (SHRSP), an animal model for hypertensive cerebral small vessel disease (CSVD). Loss of BBB is thought to be an early and initiating component to the full expression of CSVD in animal models and humans. To test this hypothesis, newly born SHRSP pups were placed with …
