Conscientious Objection To Harmful Animal Use Within Veterinary And Other Biomedical Education, 2019 Ross University School of Veterinary Medicine
Conscientious Objection To Harmful Animal Use Within Veterinary And Other Biomedical Education, Andrew Knight
Andrew Knight, Ph.D.
Laboratory classes in which animals are seriously harmed or killed, or which use cadavers or body parts from ethically debatable sources, are controversial within veterinary and other biomedical curricula. Along with the development of more humane teaching methods, this has increasingly led to objections to participation in harmful animal use. Such cases raise a host of issues of importance to universities, including those pertaining to curricular design and course accreditation, and compliance with applicable animal welfare and antidiscrimination legislation. Accordingly, after detailed investigation, some universities have implemented formal policies to guide faculty responses to such cases, and to ensure that ...
The Wet Bridge Transfer System: An Novel In Vitro Tool For Assessing Exogenous Surfactant As A Pulmonary Drug Delivery Vehicle, 2019 University of Western Ontario
The Wet Bridge Transfer System: An Novel In Vitro Tool For Assessing Exogenous Surfactant As A Pulmonary Drug Delivery Vehicle, Brandon J. Baer
Western Research Forum
Due to its complex branching structure, direct drug delivery to the remote areas of the lung is a major challenge. Consequently, most therapies, such as those treating pulmonary infection and inflammation, must utilize large systemic dosing, with the potential for adverse side effects. A novel alternative strategy is to use exogenous surfactant, a material capable of distributing throughout the lung, as a pulmonary drug delivery vehicle.
Utilize an in vitro transferring system to assess exogenous surfactant (BLES) as a pulmonary delivery vehicle for different therapeutics.
An in vitro technique was developed to simultaneously study surfactant delivery and ...
Effects Of Reduced Ph On Health Biomarkers Of The Seagrass Cymodocea Nodosa, 2019 DePaul University
Effects Of Reduced Ph On Health Biomarkers Of The Seagrass Cymodocea Nodosa, Regan A. Mcenaney
Ocean acidification is a growing problem that may affect many marine organisms in the future. Within 100 years the pH of the ocean is predicted to decrease to 7.8, from the current ocean pH of around 8.1. Using phenolic acid levels as a stress indicator as well as respiration and chlorophyll content as a measure of health, the effect of lowering pH was tested on the seagrass, Cymodocea nodosa, in a controlled environment. Plant samples, water, and soil were taken from the Bay of Cádiz, Spain, and placed in aquaria in a temperature-controlled room. One control group was ...

This article presents the design, development, and evaluation of an online forensics course created for high school students of color who were a part of an informal science, technology, engineering, and mathematics (STEM) educational development program. Two essential elements guided the course design: the target learners (high school students of color) and integrating online instruction and hands-on laboratory activities involving real-world ...
Differential Roles Of Mammalian Target Of Rapamycin Complexes 1 And 2 In Migration Of Prostate Cancer Cells, 2019 Clark Atlanta University
Differential Roles Of Mammalian Target Of Rapamycin Complexes 1 And 2 In Migration Of Prostate Cancer Cells, Smrruthi Vaidegi Venugopal
Electronic Theses & Dissertations Collection for Atlanta University & Clark Atlanta University
In this study, we investigated differential activation and the role of two mTOR complexes in cell migration of prostate cancer cells. Specific knock-down of endogenous RAPTOR and RICTOR by siRNA resulted in decreased cell migration in LNCaP, DU145, and PC3 cells indicating that both mTORC1 and mTORC2 are required for cell migration. EGF treatment induced the activation of both mTORC1 and mTORC2 as determined by complex-specific phosphorylation of mTOR protein. Specific knock-down or inhibition of Rac1 activity in PC3 cells blocked EGF-induced activation of mTORC2, but had no effect on mTORC1 activation. Furthermore, the over-expression of constitutively active Rac1 (Rac1Q61L ...

Senior Honors Projects
Advancements in medical technology today have positively impacted the diagnosis, treatment, and prognosis of cancers. Particularly acute promyelocytic leukemia (APL) has completely improved from having the poorest prognosis to one of the best. Acute promyelocytic leukemia is a malignant disease of hematopoietic tissue classified by WHO as leukemia with >20% blasts from the myeloid lineage, specifically promyelocytes. Determined in 1976, FAB classified AML subtypes M1-M7, with APL being M3. Specific characteristics classify the subtype of AML, with each resulting from a different genetic abnormality. The focus of APL diagnosis, treatment, and prognosis occurs around the known PML-RARα fusion gene. Flow ...
Seasonal Changes In Susceptibility To Chytridiomycosis In Columbia Spotted Frogs, 2019 Carroll College
Seasonal Changes In Susceptibility To Chytridiomycosis In Columbia Spotted Frogs, Delaney Burrows
Carroll College Student Undergraduate Research Festival
Chytridiomycosis is a potentially deadly skin disease found in amphibian populations all over the world. Chytridiomycosis is caused by the fungus Batrachochytrium dendrobatidis (Bd) that grows on the skin of amphibians. The fungus can cause a disruption in the homeostatic functions of the amphibian skin and can lead to death. The relationship between an amphibian’s antimicrobial skin secretions, cutaneous microbial communities and environmental water quality can affect their resistance and susceptibility to Bd infection. Columbia spotted frogs (Lithobates luteiventris) are native to western Montana and have been affected by chytridiomycosis. Three lakes known to be positive for Bd were ...

The development of an effective and safe treatment for glioblastoma (GBM) represents a significant challenge in oncology today. Downregulation of key mediators of cell signal transduction by RNA interference is considered a promising treatment strategy but requires efficient, intracellular delivery of siRNA into GBM tumor cells. Here, we describe novel polymeric siRNA nanocarriers functionalized with cRGD peptide that mediates targeted and efficient reporter gene silencing in U87R invasive human GBM cells. The polymer was synthesized via RAFT copolymerization of N-(2-hydroxypropyl)-methacrylamide (HPMA) and N-acryloxysuccinimide (NAS), followed by post-polymerization modification with cholesterol for stabilization, cationic amines for siRNA complexation, and ...
Characterizing Aft1/2-Grx3/4 Interaction And The Role Of Bol2 During Iron Regulation In Saccharomyces Cerevisiae, 2019 University of South Carolina - Columbia
Characterizing Aft1/2-Grx3/4 Interaction And The Role Of Bol2 During Iron Regulation In Saccharomyces Cerevisiae, William Rivers
Iron dysregulation has been linked to a variety of human diseases, such as anemia, Friedreich’s ataxia, X-linked sideroblastic anemia, sideroblastic-like microcytic anemia, and myopathy. Thus, it is vitally important to understand the mechanisms for regulating intracellular iron. Here, we use fluorescence microscopy techniques in live cells to study interactions of the yeast proteins Grx3/4, Aft1/2, and Bol2, which have been shown to be involved in turning off iron import when the cell has adequate iron. Modified versions of genes encoding these proteins have been incorporated into several yeast backgrounds to use fluorescence to monitor interactions under varying ...
The Effects Of Salinity On Zootechnical Performance Of Spotted Seatrout (Cynoscion Nebulosus) In Recirculating Aquaculture Systems, 2019 The University of Southern Mississippi
The Effects Of Salinity On Zootechnical Performance Of Spotted Seatrout (Cynoscion Nebulosus) In Recirculating Aquaculture Systems, Eric Gigli
The spotted seatrout (Cynoscion nebulosus) is a euryhaline finfish candidate for marine aquaculture in the northern Gulf of Mexico. Aquaculture of this species currently uses salinities of 25 psu or greater making production challenging in areas where high salinity water is not available. This study aimed to document the effects of salinity on zootechnical performance of spotted seatrout embryos, early larvae, and juveniles in recirculating aquaculture systems to assist with the development of protocols for low salinity culture.
Embryos obtained from a volitional spawn at 29 psu were incubated at three salinities (12.5, 18.75, or 25 psu) until ...

An Automated Bayesian Pipeline For Rapid Analysis Of Single-Molecule Binding Data, Carlas Smith, Karina Jouravleva, Maximiliaan Huisman, Samson M. Jolly, Phillip D. Zamore, David Grünwald
Single-molecule binding assays enable the study of how molecular machines assemble and function. Current algorithms can identify and locate individual molecules, but require tedious manual validation of each spot. Moreover, no solution for high-throughput analysis of single-molecule binding data exists. Here, we describe an automated pipeline to analyze single-molecule data over a wide range of experimental conditions. In addition, our method enables state estimation on multivariate Gaussian signals. We validate our approach using simulated data, and benchmark the pipeline by measuring the binding properties of the well-studied, DNA-guided DNA endonuclease, TtAgo, an Argonaute protein from the Eubacterium Thermus thermophilus. We ...
Day To Day And Leg To Leg Variation In Gene Expression, 2019 University of Nebraska at Omaha
Day To Day And Leg To Leg Variation In Gene Expression, Zohal Alizai
Student Research and Creative Activity Fair
BACKGROUND: Skeletal muscle biopsies are extensively used in research to determine the effects of exercise. Usually, sequential biopsies are taken before and after exercise in order to determine the influence of exercise on gene expression. Often it is not clear if the results are due to exercise or as a result of damage cause by the biopsy to the muscle. Previous studies have proven that multiple biopsies in the same leg cause stress to the muscle and such stress leads to inflammation and other response pathways that alter the gene expression. PURPOSE: The purpose of this study is to determine ...
