Long-Term Implications Of Neonatal Canine Caudectomies, 2020 Murray State University
Long-Term Implications Of Neonatal Canine Caudectomies, Estefania Benavides
Honors College Theses
Tail docking is an ongoing procedure several canine breeders choose to practice in order to preserve the expected appearance of certain breeds, as defined by the American Kennel Club (AKC). The spinal nerves are severed between the two caudal vertebrae of the neonate without the use of any anesthetics, local or general. The inability for the neonates to properly metabolize anesthetics contraindicates its administration. According to the American Veterinary Medical Association (AVMA), only two states in the United States have any sort of provision regarding canine caudectomies, and they are Maryland and Pennsylvania Generally in other states, experienced breeders and ...
Clinically Relevant 3d Characterization Of Simulated Non-Carious Cervical Dental Lesions And The Effects Of Toothbrush And Toothpaste Types On Wear, 2020 University of Arkansas, Fayetteville
Clinically Relevant 3d Characterization Of Simulated Non-Carious Cervical Dental Lesions And The Effects Of Toothbrush And Toothpaste Types On Wear, James Needy
Biomedical Engineering Undergraduate Honors Theses
This study sought to develop a novel method to quantitatively characterize non-carious cervical lesions (NCCLs) using an intraoral scanner (IOS) paired with Geomagic Wrap mesh software. The goal was to compare results with those obtained using an optical profilometer and Proscan superimposition software for clinical application. Comparisons were made using a previously published dataset aimed at measuring tooth loss associated with differing toothbrush and toothpaste types. Results show good comparability between methods and confirm that variation in brush stiffness and paste abrasivity result in significantly and predictably different levels of NCCL development. Extracted human maxillary premolars were assigned to one ...

We aimed to identify cumulative incidence, demographic distribution, and undetected disease outbreaks of Legionella pneumonia via positive LUAT in a single eastern Wisconsin health system, with a focus on urban Milwaukee County.
Methods: A multilevel descriptive ecologic study was conducted utilizing electronic medical record data from a large integrated health care system of patients who underwent LUAT from 2013 to 2017. A random sample inclusive of all positive tests was reviewed to investigate geodemographic differences among patients testing positive versus negative. Statistical comparisons ...
Ganglioside Detection From Formalin Fixed Human Brain Tissue Utilizing Maldi Imaging Mass Spectrometry, 2020 The University of Western Ontario
Ganglioside Detection From Formalin Fixed Human Brain Tissue Utilizing Maldi Imaging Mass Spectrometry, Aaron Harris
Electronic Thesis and Dissertation Repository
Matrix assisted laser desorption ionization (MALDI) imaging mass spectrometry (IMS) is largely performed on fresh frozen tissue whereas clinical tissue samples stored long term are fixed in formalin, and the fixation process is thought to cause signal suppression for lipid molecules. Studies show that fresh frozen brain tissue sections washed with ammonium formate (AF) solution prior to matrix application in the MALDI-IMS procedure display an increase in signal intensity and sensitivity for lipid molecules while maintaining molecular spatial distribution. Work in this thesis compares MALDI data of ganglioside molecules from fresh frozen and post-fixed rat brain samples, and post-fixed human ...

University of Massachusetts Medical School Faculty Publications
The laboratory mouse is the most widely used animal model for biomedical research, due in part to its well annotated genome, wealth of genetic resources and the ability to precisely manipulate its genome. Despite the importance of genetics for mouse research, genetic quality control (QC) is not standardized, in part due to the lack of cost effective, informative and robust platforms. Genotyping arrays are standard tools for mouse research and remain an attractive alternative even in the era of high-throughput whole genome sequencing. Here we describe the content and performance of a new Mouse Universal Genotyping Array (MUGA). MiniMUGA, an ...
Detecting Chromatin Interactions Along And Between Sister Chromatids With Sisterc, 2020 University of Massachusetts Medical School
Detecting Chromatin Interactions Along And Between Sister Chromatids With Sisterc, Marlies E. Oomen, Adam K. Hedger, Jonathan K. Watts, Job Dekker
University of Massachusetts Medical School Faculty Publications
Accurate chromosome segregation requires chromosome compaction with concordant disentanglement of the two sister chromatids. This process has been studied extensively by microscopy but has remained a challenge for genomic methods, such as Hi-C, because sister chromatids have identical DNA sequences. Here we describe SisterC, a chromosome conformation capture assay that can distinguish interactions between and within sister chromatids. The assay is based on BrdU incorporation during S-phase, which labels the newly replicated strands of the sister chromatids. This is followed by Hi-C, e.g. during different stages of mitosis, and the selective destruction of BrdU containing strands by UV/Hoechst ...

Mouse models of human disease remain the bread and butter of modern biology and therapeutic discovery. Nonetheless, more often than not mouse models do not reproduce the pathophysiology of the human conditions they are designed to mimic. Naturally occurring large animal models have predominantly been found in companion animals or livestock because of their emotional or economic value to modern society and, unlike mice, often recapitulate the human disease state. In particular, numerous models have been discovered in dogs and have a fundamental role in bridging proof of concept studies in mice to human clinical trials. The present article is ...

In Drosophila, transposon-silencing piRNAs are derived from heterochromatic clusters and a subset of euchromatic transposon insertions, which are bound by the Rhino-Deadlock-Cutoff complex. The HP1 homolog Rhino binds to Deadlock, which recruits TRF2 to promote non-canonical transcription from both genomic strands. Cuff function is less well understood, but this Rai1 homolog shows hallmarks of adaptive evolution, which can remodel functional interactions within host defense systems. Supporting this hypothesis, Drosophila simulans Cutoff is a dominant-negative allele when expressed in Drosophila melanogaster, in which it traps Deadlock, TRF2, and the conserved transcriptional co-repressor CtBP in stable complexes. Cutoff functions with Rhino and ...
Population Modeling Of Tumor Growth Curves And The Reduced Gompertz Model Improve Prediction Of The Age Of Experimental Tumors, Cristina Vaghi, Anne Rodallec, Raphaelle Fanciullin, Joseph Ciccolini, Jonathan P. Mochel, Michalis Mastri, Clair Poignard, John M. L. Ebos, Sebastien Benzekry
Biomedical Sciences Publications
Tumor growth curves are classically modeled by means of ordinary differential equations. In analyzing the Gompertz model several studies have reported a striking correlation between the two parameters of the model, which could be used to reduce the dimensionality and improve predictive power. We analyzed tumor growth kinetics within the statistical framework of nonlinear mixed-effects (population approach). This allowed the simultaneous modeling of tumor dynamics and inter-animal variability. Experimental data comprised three animal models of breast and lung cancers, with 833 measurements in 94 animals. Candidate models of tumor growth included the exponential, logistic and Gompertz models. The exponential and ...

Open Access Articles
The prevalence of tickborne diseases worldwide is increasing virtually unchecked due to the lack of effective control strategies. The transmission dynamics of tickborne pathogens are influenced by the tick microbiome, tick co-infection with other pathogens, and environmental features. Understanding this complex system could lead to new strategies for pathogen control, but will require large-scale, high-resolution data. Here, we introduce Project Acari, a citizen science-based project to assay, at single-tick resolution, species, pathogen infection status, microbiome profile, and environmental conditions of tens of thousands of ticks collected from numerous sites across the United States. In the first phase of the project ...
Prediction Of Molecular Mutations In Diffuse Low-Grade Gliomas Using Mr Imaging Features, 2020 Old Dominion University
Prediction Of Molecular Mutations In Diffuse Low-Grade Gliomas Using Mr Imaging Features, Zeina A. Shboul, James Chen, Khan M. Iftekharrudin
Electrical & Computer Engineering Faculty Publications
Diffuse low-grade gliomas (LGG) have been reclassified based on molecular mutations, which require invasive tumor tissue sampling. Tissue sampling by biopsy may be limited by sampling error, whereas non-invasive imaging can evaluate the entirety of a tumor. This study presents a non-invasive analysis of low-grade gliomas using imaging features based on the updated classification. We introduce molecular (MGMT methylation, IDH mutation, 1p/19q co-deletion, ATRX mutation, and TERT mutations) prediction methods of low-grade gliomas with imaging. Imaging features are extracted from magnetic resonance imaging data and include texture features, fractal and multi-resolution fractal texture features, and volumetric features. Training models ...
Spectrographic Analysis Of The Lombard Effect, 2020 The University of Akron
Spectrographic Analysis Of The Lombard Effect, Julia Saxon
Williams Honors College, Honors Research Projects
In my honors project I will study the feasibility of using spectrographic analysis to measure the Lombard effect. The Lombard effect is a well-known phenomenon in which talkers reflexively increase the intensity of their voices in the presence of background noise. We hypothesize that other measurable features of speech will also change with vocal intensity consistent with what is shown in literature. However, the current authors will discuss findings in terms of its potential value as a test of pseudohypoacusis, also known as nonorganic or functional hearing loss. The author and a licensed audiologist will examine the /i/ and /u ...

This study aims to analyze data from a pool of 100 patients who underwent testing for tick-borne disease in the same institution in Dover, New Hampshire during the most recent peak tick season of 2019. Information utilized in this study included: patient age, sex, location of testing (inpatient versus outpatient), diagnostic testing methods used ...
Evaluating The Occurrence Of Age-Related Peripheral Neuropathy In Het3 Mice And Development Of A Whole Tissue Imaging Technique For Analyzing Total Innervation In The Subcutaneous Adipose Depot, 2019 University of Maine
Evaluating The Occurrence Of Age-Related Peripheral Neuropathy In Het3 Mice And Development Of A Whole Tissue Imaging Technique For Analyzing Total Innervation In The Subcutaneous Adipose Depot, Jake Willows
Electronic Theses and Dissertations
Adipose tissue can be characterized as either being a white (energy storing) depot or a brown (energy expending) depot and both have been found to contain dense networks of neural innervation. This adipose nerve supply regulates numerous metabolic functions and likely plays an important role in the function of adipose blood vessels. Recently our lab has shown in the C57BL/6 mouse model that peripheral neuropathy, or the dying back and dysfunction of the nerves in the superficial tissues such as the skin, can extend into the subcutaneous adipose tissue in conditions commonly associated with the neuropathic phenotype (i.e ...

School of Medicine Faculty Publications
Background/Aims: Endoscopic retrograde cholangiopancreatography (ERCP) is a technically challenging procedure rarely associated with severe postprocedure complications. Hormonal changes during pregnancy promote cholelithiasis, but there are limited clinical data available on the outcomes of ERCP in pregnant women. ERCP techniques without irradiation were recently introduced as potential alternative. We performed a systematic review and meta-analysis to assess the safety of ERCP in pregnancy and to compare outcomes of radiation versus nonradiation ERCP. Materials and Methods: A systematic search of PubMed, Medline/Ovid, Web of Science, and Google Scholar through April 18th, 2018 using PRISMA and MOOSE guidelines identified 27 studies ...
