Dugesia Japonica Is The Best Suited Of Three Planarian Species For High-Throughput Toxicology Screening, D. Ireland, Veronica Bochenek , '22, Daniel Chaiken , '20, C. Rabeler, Sumi Onoe , '21, Ameet Soni, Eva-Maria S. Collins

Biology Faculty Works

High-throughput screening (HTS) using new approach methods is revolutionizing toxicology. Asexual freshwater planarians are a promising invertebrate model for neurotoxicity HTS because their diverse behaviors can be used as quantitative readouts of neuronal function. Currently, three planarian species are commonly used in toxicology research: Dugesia japonica, Schmidtea mediterranea, and Girardia tigrina. However, only D. japonica has been demonstrated to be suitable for HTS. Here, we assess the two other species for HTS suitability by direct comparison with D. japonica. Through quantitative assessments of morphology and multiple behaviors, we assayed the effects of 4 common solvents (DMSO, ethanol, methanol, ethyl acetate ...


Ethics And Familiarity With Elephant Population Management, Katelyn Shook Apr 2020

Ethics And Familiarity With Elephant Population Management, Katelyn Shook

Honors Theses

Biologists study population statuses because, while many species are considered healthy, others are overpopulated or vulnerable to extinction. Assessing the extinction risk for various species on earth can be a difficult task. The International Union for Conservation of Nature(IUCN) is the global authority in charge of assessing a species’ status and putting it on the “Red List” (Blanc 2008). This IUCN Red List uses scientific studies such as population assessments and threat assessments to properly label a species as least concern, near threatened, vulnerable, endangered, critically endangered, extinct in the wild, or extinct (NRDC 2016). Within these categories, least ...

The History Of Farm Foxes Undermines The Animal Domestication Syndrome, Kathryn A. Lord, Greger Larson, Raymond P. Coppinger, Elinor K. Karlsson Dec 2019

The History Of Farm Foxes Undermines The Animal Domestication Syndrome, Kathryn A. Lord, Greger Larson, Raymond P. Coppinger, Elinor K. Karlsson

Program in Bioinformatics and Integrative Biology Publications

The Russian Farm-Fox Experiment is the best known experimental study in animal domestication. By subjecting a population of foxes to selection for tameness alone, Dimitry Belyaev generated foxes that possessed a suite of characteristics that mimicked those found across domesticated species. This 'domestication syndrome' has been a central focus of research into the biological pathways modified during domestication. Here, we chart the origins of Belyaev's foxes in eastern Canada and critically assess the appearance of domestication syndrome traits across animal domesticates. Our results suggest that both the conclusions of the Farm-Fox Experiment and the ubiquity of domestication syndrome have ...

Georgia Undergraduate Research Conference (GURC)

There is a growing concern in the U.S. about genetically modified (GM) or GMO foods and consumers are demanding proper disclosure. Public Law 114-216 passed July 29, 2016 also known as the ‘GMO labeling bill’, where the USDA established a National Bioengineered Food Disclosure Standard (NBFDS) stating manufacturers are not required to label products if genetic material is undetected3. Bioengineered food is defined as a food that has been modified through the insertion of in vitro recombinant deoxyribonucleic acid techniques, per NBFDS. Because corn is currently in the bioengineered lists of crops and 93% of corn produced in ...

Micrornas Are Necessary For Bmp-7-Induced Dendritic Growth In Cultured Rat Sympathetic Neurons, Vidya Chandrasekaran Sep 2019

Micrornas Are Necessary For Bmp-7-Induced Dendritic Growth In Cultured Rat Sympathetic Neurons, Vidya Chandrasekaran

Vidya Chandrasekaran

Neuronal connectivity is dependent on size and shape of the dendritic arbor. However, mechanisms controlling dendritic arborization, especially in the peripheral nervous system, are not completely understood. Previous studies have shown that bone morphogenetic proteins (BMPs) are important initiators of dendritic growth in peripheral neurons. In this study, we examined the hypothesis that post-transcriptional regulation mediated by microRNAs (miRNAs) is necessary for BMP-7-induced dendritic growth in these neurons. To examine the role of miRNAs in BMP-7-induced dendritic growth, microarray analyses was used to profile miRNA expression in cultured sympathetic neurons from the superior cervical ganglia of embryonic day 21 rat ...

Force Requirements And Force Generation During Endocytosis In Yeast, Jonah Kyle Scher-Zagier Aug 2019

Force Requirements And Force Generation During Endocytosis In Yeast, Jonah Kyle Scher-Zagier

Arts & Sciences Electronic Theses and Dissertations

Endocytosis is a process by which cells bring external materials into the intracellular environment and perform other essential biological functions. The main drivers of endocytosis include clathrin and actin, which help shape the membrane and form the endocytic invagination. In mammalian cells and other cells lacking a wall, the primary barriers to endocytosis are the bending rigidity of the cell membrane and surface tension. However, in cells with a rigid cell wall, such as those of yeast, this process is opposed by a substantial pressure within the cell, known as the turgor pressure, which is generated by a difference in ...


Hydrocarbon Concentration Data Collected During A Coastal Survey Conducted In The Bay Of Campeche, Southern Gulf Of Mexico On 2016-08-09, Isabel Romero Aug 2019

Hydrocarbon Concentration Data Collected During A Coastal Survey Conducted In The Bay Of Campeche, Southern Gulf Of Mexico On 2016-08-09, Isabel Romero

C-IMAGE data

On 2016 a coastal survey was conducted in the Bay of Campeche (Mexico) to search for remnants of the Ixtoc-1 spill. This spill occurred on June 3 of 1979 releasing about 3 million barrels of oil during 9.75 months. In the aftermath of the spill (1979-1980), a survey conducted by Texas A&M University-Corpus Christi indicated oil reached and impacted several areas, including mangroves, reefs and rocky beaches. Previous visual surveys and observations from locals confirmed the coastal areas were not impacted by oil before the Ixtoc-1 spill. In 2016, C-IMAGE II researchers conducted a similar survey with the ...

Outward Currents Contributing To Inspiratory Burst Termination In Prebotzinger Complex Neurons Of Neonatal Mice Studied In Vitro, Rebecca Kray, Adam M. Goodreau, Thomas B. Arnold, Christopher A. Del Negro Jul 2019

Outward Currents Contributing To Inspiratory Burst Termination In Prebotzinger Complex Neurons Of Neonatal Mice Studied In Vitro, Rebecca Kray, Adam M. Goodreau, Thomas B. Arnold, Christopher A. Del Negro

Christopher Del Negro

We studied pre-Botzinger(preBotC) inspiratory interneurons to determine the cellular mechanisms that influence burst termination in a mammalian central pattern generator. Neonatal mouse slice preparations that retain pre-BoTC neurons generate respiratory motor rhythms in vitro. Inspiratory-related bursts rely on inward currents that flux Na+, thus outward currents coupled to Na+ accumulation are logical candidates for assisting in, or causing, burst termination. We examined Na+/K+/ATPase electrogenic pump current (Ipump), Na+-dependent K+ current, and ATP-dependent K+ current (IK-ATP). The pharmacological blockade of IPUMP, IK-Na, or IK-ATP caused pathological depolarization akin to a burst that ...
