A Comparison Of Agent-Based Models And Equation Based Models For Infectious Disease Epidemiology, Elizabeth Hunter, Brian Mac Namee, John D. Kelleher 2018 Dublin Institute of Technology

A Comparison Of Agent-Based Models And Equation Based Models For Infectious Disease Epidemiology, Elizabeth Hunter, Brian Mac Namee, John D. Kelleher

Articles

There are two main methods that are used to model the spread of an infectious disease: agent-based modelling and equation based modelling. In this paper, we compare the results from an example implementation of each method, and show that although the agent-based model takes longer to setup and run, it provides additional information that is not available when using an equation based model. Specifically, the ability of the agent-based model to capture heterogeneous mixing and agent interactions enables it to give a better overall view of an outbreak. We compare the performance of both models by simulating a measles outbreak ...


Modeling In The Physiology Classroom, Sowmya Anjur 2018 Illinois Mathematics and Science Academy

Modeling In The Physiology Classroom, Sowmya Anjur

Faculty Publications & Research

Physiology and Disease is a Biology elective at IMSA that has been developed to be mostly student-centered. Some examples of student projects include modeling heart structure to reflect function and creating LED arduino monitors to measure heart rate. Students also measure their lung capacity and blood pressure to demonstrate correlation of these values with heart rate, and trace the correlation back to neuronal controls. Projects such as these integrate other disciplines such as engineering and conform to NGSS Science and Engineering standards and NGSS Cross cutting Concepts standards. Students take responsibility for their own learning and articulate better on tests.


Vancomycin Delays Clindamycin-Induced Fatality In The Hamster Model Of Clostridioides [Clostridium] Difficile Infection, Amelia E. Fox-King, Chrisabelle Mefferd, Jacqueline R. Phan, Nancy O. Nou, Ernesto Abel-Santos, Brian P. Hedlund 2018 University of Nevada, Las Vegas

Vancomycin Delays Clindamycin-Induced Fatality In The Hamster Model Of Clostridioides [Clostridium] Difficile Infection, Amelia E. Fox-King, Chrisabelle Mefferd, Jacqueline R. Phan, Nancy O. Nou, Ernesto Abel-Santos, Brian P. Hedlund

LSAMP Poster Presentations

Antibiotics can leave the host gut microbiome susceptible to Clostridioides [Clostridium] difficile colonization and lethal toxin production. For instance, clindamycin-induced susceptibility to C. difficile infection (CDI) results in rapid fatality in hamster models, yet vancomycin has been shown to offer increased survival in hamsters challenged with C. difficile. We aim to develop an antibiotic treatment that will facilitate CDI susceptibility without prompt fatality in hamster models. An antibiotic regimen starting with a continuous vancomycin treatment along with a single clindamycin dosage is thought to reduce the major disruption in the indigenous gut microbiome and prevent clindamycin-induced death. Quantitative polymerase chain ...

Genetic Modification Of Inherited Retinopathy In Mice, Yang Kong 2018 The University of Maine

Genetic Modification Of Inherited Retinopathy In Mice, Yang Kong

Electronic Theses and Dissertations

The retina, as a critical component of the sensory system, consists of multiple cell types, of which, photoreceptors play a key role in receiving, integrating and transmitting light signals. The biofunctions of photoreceptors rely on their proper growth and development, which is predominantly governed by a cluster of molecules that comprise the transcriptional regulation for photoreceptor development. Any disruption of these molecules potentially incurs retinal pathologies.

It is known that deficiencies of nuclear receptor subfamily 2 group E member 3 (NR2E3) or neural retina leucine-zipper (NRL), two molecules in regulating photoreceptor cell development, cause photoreceptor dysplasia. In a sensitized chemical ...


Changes In The Testes Following Spinal Cord Injury And The Attenuating Effects Of Licofelone, Ryan Fortune 2018 The University of Texas M D Anderson Cancer Center UTHealth Graduate School of Biomedical Sciences

Changes In The Testes Following Spinal Cord Injury And The Attenuating Effects Of Licofelone, Ryan Fortune

UT GSBS Dissertations and Theses (Open Access)

Spinal cord injury is a devastating disease that researchers have had very limited success in treating. In addition to interrupted innervation, spinal cord injury causes pathologic changes in a multitude of organ systems. Male infertility is one such complication that is particularly devastating because the patient population is predominantly young men. Our lab has previously shown that the blood testis barrier breaks down after spinal cord injury. This dissertation shows the local metabolomic and mRNA changes that spinal cord injury causes within the testes using a Sprague Dawley rat model, including the elevation in eicosanoids, increased oxidative stress, chronically elevated ...


Developing Droplet Based 3d Cell Culture Methods To Enable Investigations Of The Chemical Tumor Microenvironment, Jacqueline A. De Lora 2018 University of New Mexico - Main Campus

Developing Droplet Based 3d Cell Culture Methods To Enable Investigations Of The Chemical Tumor Microenvironment, Jacqueline A. De Lora

Biomedical Sciences ETDs

Adaptation of cancer cells to changes in the biochemical microenvironment in an expanding tumor mass is a crucial aspect of malignant progression, tumor metabolism, and drug efficacy. In vitro, it is challenging to mimic the evolution of biochemical gradients and the cellular heterogeneity that characterizes cancer tissues found in vivo. It is well accepted that more realistic and controllable in vitro 3D model systems are required to improve the overall cancer research paradigm and thus improve on the translation of results, but multidisciplinary approaches are needed for these advances. This work develops such approaches and demonstrates that new droplet-based cell-encapsulation ...

Preventing P-Gp Ubiquitination Lowers Aβ Brain Levels In An Alzheimer's Disease Mouse Model, Anika M. S. Hartz, Yu Zhong, Andrew N. Shen, Erin L. Abner, Björn Bauer

Sanders-Brown Center on Aging Faculty Publications

One characteristic of Alzheimer’s disease (AD) is excessive accumulation of amyloid-β (Aβ) in the brain. Aβ brain accumulation is, in part, due to a reduction in Aβ clearance from the brain across the blood-brain barrier. One key element that contributes to Ab brain clearance is P-glycoprotein (P-gp) that transports Aβ from brain to blood. In AD, P-gp protein expression and transport activity levels are significantly reduced, which impairs Aβ brain clearance. The mechanism responsible for reduced P-gp expression and activity levels is poorly understood. We recently demonstrated that Aβ40 triggers P-gp degradation through the ubiquitin-proteasome pathway. Consistent with ...

Carbamyl phosphate (CP) is well-known as an essential intermediate of pyrimidine and arginine/urea biosynthesis. Chemically, CP can be easily synthesized from dihydrogen phosphate and cyanate. Enzymatically, CP can be synthesized using three different classes of enzymes: (1) ATP-grasp fold protein based carbamyl phosphate synthetase (CPS); (2) Amino-acid kinase fold carbamate kinase (CK)-like CPS (anabolic CK or aCK); and (3) Catabolic transcarbamylase. The first class of CPS can be further divided into three different types of CPS as CPS I, CPS II, and CPS III depending on the usage of ammonium or glutamine as its nitrogen source, and whether


Characterizing The Role Of Fungal Shape In A Zebrafish Model Of Invasive Candidiasis, Brittany Seman 2018 University of Maine

Characterizing The Role Of Fungal Shape In A Zebrafish Model Of Invasive Candidiasis, Brittany Seman

Electronic Theses and Dissertations

Candida albicans is a common hospital-acquired fungal infection, and disseminated disease claims up to one-half of those afflicted. C. albicans has a unique ability to differentiate its shape during infection, and this differentiation is thought to be a major virulence factor during invasive infections. Each shape is proposed to have a specialized role: filaments drive tissue invasion and yeast mediate dissemination to the bloodstream. However, it has been difficult to test these hypotheses for two reasons. First, rigorous testing of shape-specific roles requires diverse strategies of shape modulation that restrict the possibility of manipulation-specific artifacts. Second, although connecting shape to ...

In Vitro Aortic Arch Flow Model For Vector Flow Imaging Testing, Jackson Mosley 2018 University of Arkansas, Fayetteville

In Vitro Aortic Arch Flow Model For Vector Flow Imaging Testing, Jackson Mosley

Biomedical Engineering Undergraduate Honors Theses

Pediatric stenosis is the narrowing of the aorta at the aortic valve, above the aortic valve, or below the aortic valve. Typically, this disease’s severity is diagnosed by conventional Doppler ultrasound methods, or echocardiography. Conventional Doppler can sometimes overestimate the pressure gradient over the area of stenosis, diagnosing some cases of PAS to be more severe than they actually are. This causes earlier intervention than is desired in children. A new US modality, Vector Flow Imaging (VFI), is an angle-independent US imaging method that can potentially more accurately quantify peak blood flow velocities and pressure gradients across stenotic sections ...
