Dha But Not Epa Induces The Trans-Differentiation Of C2c12 Cells Into White-Like Adipocytes Phenotype, Saeed Jebor Ghnaimawi, Lisa Rebello, Jamie Baum, Yan Huang

Food Science Faculty Publications and Presentations

Muscle derived stem cells (MDSCs) and myoblast play an important role in myotube regeneration when muscle tissue is injured. However, these cells can be induced to differentiate into adipocytes once exposed to PPARγ activator like EPA and DHA that are highly suggested during pregnancy. The objective of this study aims at determining the identity of trans-differentiated cells by exploring the effect of EPA and DHA on C2C12 undergoing differentiation into brown and white adipocytes. DHA but not EPA committed C2C12 cells reprograming into white like adipocyte phenotype. Also, DHA promoted the expression of lipolysis regulating genes but had no effect …

Ten Years On: Engaging The Public Through The Archaeology Roadshow, Virginia L. Butler, Lyssia Merrifield, Virginia Parks, Shelby Anderson

Anthropology Faculty Publications and Presentations

Public engagement is a critical part of archaeologists’ tool kit for encouraging people to look beyond the glittering but superficial appeal of “artifacts” to appreciate and respect the peoples and cultures that made them. Engagement takes many forms—from museum exhibits, archaeological site tours, K–12 curriculum, and social media to heritage tourism, documentary films, and more. Whatever the medium or approach, a common goal is to increase the public’s understanding of the broader values archaeology strives to promote (e.g., scientific literacy, cultural diversity, civic engagement, critical thinking) and to open the door for discussion of the ethical and moral issues surrounding …

Department of Molecular and Cellular Biology

Abstract

Salmonella and Shigella are two important groups of foodborne bacterial pathogens. Salmonella cause an illness called salmonellosis while Shigella cause shigellosis (bacillary dysentery). The most common symptoms of these illnesses are abdominal cramps, diarrhea, and fever. Shigella can also cause bloody diarrhea. It was estimated that each year Salmonella cause 93.8 million cases of gastroenteritis and 155,000 deaths globally. Shigella causes 164.7 million cases and 1.1 million deaths throughout the world yearly. People get these illnesses mainly by …

Empire, Autochthony, And Identity In Fifth-Century Athens

Symposium of Student Scholars

The fifth-century BCE is a period of Athenian history that is bookended by conflict. It began with the Persian Wars, which established Athens as a major power and gave them claim to their empire. The period ended with the Peloponnesian War, which resulted in the defeat of Athens and the end of their imperial reign. The fifth-century was a period of unprecedented cultural, political, and ideological development, and is one of the most important periods in all of Greek history. Despite the various developments that occurred in the fifth-century, most of the scholarship on fifth-century Athens is concerned with the …

S-Layer Increases Predation Ability Of Myxococcus Xanthus

Symposium of Student Scholars

Background: Myxococcus xanthus is a gram-negative soil bacterium that exhibits micro-predatory activities. When starved, M. xanthus produces resistant spores within fruiting bodies for survival. The S-layer is a paracrystalline structure intertwined in many different patterns and is composed of proteins or glycoproteins. A species that produces the S-layer is Aeromonas. A. salmonicida is a strain of Aeromonas that infects fish. A. hydrophila is another pathogenic strain that causes a wide range of human diseases. We investigated the ability of the S-layer to protect Aeromonas from predation by Myxobacteria. Methods: Myxococcus and prey Aeromonas cultures were standardized to a concentration …

Analysis And Characterization Of Microplastics In Water Treatment Plants

Symposium of Student Scholars

Plastic pollution is a growing public concern due to its effect on our environment and oceans. Based on the increasing prevalence of microplastics in the environment, they are now present in potable water. Microplastics can be defined as pieces of synthetic polymers that can typically be measured to be smaller than five millimeters. Microplastics can stem from sources such as beauty products containing microbeads, polystyrene foam packaging, and the deterioration of disposable plastic items. Much of this waste enters natural water bodies, which is the source of our drinking water. Little is known about the microplastics contaminating our water treatment …

Does Cortisol Respond To A Social Perturbation In Captive Bonobos?, Tiffany Ly

Symposium of Student Scholars

All animals are influenced by their environment. For social species, this means that changes in group size or composition can have long-lasting effects on survival or reproduction. When these social species are placed in captivity and new individuals are introduced suddenly by zookeepers or researchers, these events can lead to stress by changing established dominance hierarchies. For example, these interactions can cause stress hormones—like cortisol in primates and humans—to be released in response to meeting unfamiliar individuals. We took advantage of an introduction event happening at a captive research and conservation facility to better understand how introducing a new female …

The purpose of this research paper is to discuss the representation of Native Americans in film and how it affects people’s perception of Native Americans. It looks at the negative associations with Native Americans that viewers tend to think of when viewing cinema, and it discusses the help and harm it has done to the Native American community. I used evidence from classic and contemporary films, Buffalo Bill’s Wild West Show, older genre …

Implications Of Visual Social Access On The Welfare And Behavior Of Shelter Dogs, Christina M. Walthers, Madison J. Pattillo, Jessie A. Catchpole, Lauren E. Faulkner, Lauren N. Mitchell, Allison L. Martin

Symposium of Student Scholars

Animal shelter environments have many stressful factors that impact the welfare of shelter dogs, such as lack of predictability and control, and social isolation. Social isolation has been found to increase abnormal behavior and lead to poorer adoption outcomes. Providing visual access to shelter dogs is a relatively easy environmental modification that increases social opportunities and allows for more predictability and control over the environment, potentially improving welfare. To investigate the impact of visual access on the behavior of dogs, we used a within-subject design, conducting 5-min focal observations four times weekly before, during, and after visual access was provided …

Securing Global Positioning Systems In A Blockchain Using Vehicle-To-Everything Communications, Malik Purefoy

Symposium of Student Scholars

Intelligent transportation systems (ITS) are being deployed globally to support vehicular safety innovation using wireless communication. The ITS paradigm of vehicle-to-everything communication (V2X) enables vehicles equipped with an on-board unit (OBU) to communicate with a roadside unit (RSU) infrastructure to provide safe intersection movements between similarly equipped vehicles, pedestrians, and animal life. However, the current paradigm relies heavily on the availability of a Global Positioning System (GPS) for ensuring road user safety. In a doomsday scenario where GPS becomes unavailable, collision avoidance services provided through V2X may be rendered unavailable. The proposed solution is to develop a secure and reliable …

Effects Of Essential Oils On Shelter Dog Behavior, Madison Pattillo

Symposium of Student Scholars

Shelter environments are stressful for dogs due to loud noises and unfamiliar surroundings. Dogs rely heavily on scent information, and exposure to some scents has shown reductions in activity and vocalizations in shelter dogs. We investigated the effects of two calming (lavender and vetiver) and two stimulating (lemon and rosemary) essential oils on crate position and active, resting, and stress behaviors. Observations were conducted for 5-min intervals eight times per week, with observations split between baseline and scent exposure. Our preliminary analysis using the Wilcoxon Signed-Rank test found that dogs exposed to lavender (n = 13), lemon (n = 9), …

Impact Of Human Presence And Visual Access On Barking Behavior In Shelter Dogs, Emily W. Dowling, Jessie A. Catchpole, Christina M. Walthers, Madison J. Pattillo

Symposium of Student Scholars

Shelters can be stressful for dogs due to lack of predictability and control, social isolation, and busy environments. Providing dogs with more social opportunities and environmental predictability may improve their welfare. Barking may indicate stress and contribute to noise levels that are harmful to dogs and people. We investigated the impact of human presence and line of sight on barking. We manipulated line of sight by partially removing a crate barrier to allow the dogs visual access to other dogs and a better view of the room. We collected data on barking on 17 focal dogs as well as overall …

A Reevaluation Of The Phylogeography Of The Chattahoochee Slimy Salamander (Plethodon Chattahoochee) Using Next-Generation Genomic Data, Jadin Cross

Symposium of Student Scholars

The Plethodon glutinosus species complex is a group of large-bodied, lungless salamanders that are widespread across the eastern United States. Species in this group are morphologically cryptic and were originally delimited using allozyme data, but in most cases, the extent of contemporary gene flow between named taxa has not be rigorously evaluated. The Appalachian Mountains of northern Georgia are home to several members of this group—including P. glutinosus, P. teyahalee, P. chlorobryonis, and P. chattahoochee. P. chattahoochee has been found to be especially cryptic both morphologically and genetically as both intraspecific genetic variation and species boundaries within …

The Evolutionary Origins Of Autism Associated Genes And Their Role In Great Ape Socio-Communication, Azeeza Abdulrauf, Martin Hudson, Susan M.E. Smith, Jared P. Taglialatela

Symposium of Student Scholars

Single nucleotide polymorphisms (SNPs) play a major role in socio-communicative behavior. For this study, the focus is on autism associated OXTR, AVPR1A, and FOXP2 SNPs, and the role they play in great apes. Prior research on the OXTR, AVPR1A, and FOXP2 SNPs show that they affect behavior skills such as understanding and controlling emotion, understanding the emotions of others, and communications skills. Great apes, such as bonobos, chimpanzees, and gorillas are the model, since they are our closest relatives in the animal kingdom capable of understanding complex communication. Each gene has at least two SNPS that are investigated in the …

Laryngeal Vocals In Old World Locals: Air Sacs Usage In Bonobos, Chelsea Trenbeath

Symposium of Student Scholars

Except for humans, extant great apes have evolutionarily conserved lateral ventricular air sacs extending from laryngeal saccules. Humans are the only species of Hominidae that lack this anatomical feature attached to the primary vocal apparatus. As we are the only species that produces spoken language, this association has led to hypothesis that the loss of lateral ventricular air sacs was necessary for the evolution of spoken language. However, why these sacs are conserved in all other hominids remains unclear. Computer modeling has indicated that air sacs may increase resonance properties, but there are no data from great apes indicating which …

Plant-Based Vs. Animal-Based Diet And Their Association With Metabolic Function, Gwyneth Johnson, Mara Bryan, Andreana Henry, Grace Alexander

Symposium of Student Scholars

Diet is a lifestyle factor that influences metabolic health. Recent studies indicate that substituting red or processed meat with whole grains may reduce risk for type 2 diabetes. PURPOSE: To investigate whether metabolic health, assessed by insulin sensitivity and abdominal adiposity, is associated with a higher animal-based and lower plant-based diet. METHODS: Intra-abdominal adipose tissue (IAAT) was measured via ultrasound in 31 normo-glycemic women (ages 20.9 ±2.4 years, BMI 28.1 ±3.5) who completed ASA24 diet recall and food frequency questionnaire. Insulin sensitivity was assessed using Matsuda Index from a 2-hour oral glucose tolerance test. A diet scoring system was created …

Linguistic Diversity, Equity And Health: ‘Do You Speak Covid-19?’, Laila C.A. Helmi

BAU Journal - Society, Culture and Human Behavior

With many languages of the world becoming marginalized, discriminated against and at times even facing extinction, the linguistic landscape of the medical and health-care context suffers many challenges. Most prominently, when medical / health staff and their patients do not speak the same language, health-care disparities arise. With COVID-19 sweeping through the world, language barriers multiplied, access to information became a privilege conditional upon competence in English or one of the major world languages, people’s perception of the pandemic became confused and health care was adversely affected. This paper attempts a review of some of the research conducted on the …

Exploring Potentials Of Leftover Spaces Using Urban Metamorphosis, Huda Maatouk, Marwan Halabi, Hiba Mohsen, Maged Youssef

BAU Journal - Society, Culture and Human Behavior

In a dynamic world, the challenge behind reaching utopia is a result of the continuity of change and the metamorphosis. Metamorphosis, from the Greek meta signifying the change and morphe referring to the form, is a change and adaptation of the form or nature of something into a different one through time. However, when it comes to urban metamorphosis, it is a tension between the traditional living and the raise of technology through history, and this adaptation is affecting cities, buildings, identity, and environment. Urban metamorphosis of undeveloped non-organized cities had created urban and social fragmentation; unorganized cities are broken …

Gradient Free Sign Activation Zero One Loss Neural Networks For Adversarially Robust Classification, Yunzhe Xue

Dissertations

The zero-one loss function is less sensitive to outliers than convex surrogate losses such as hinge and cross-entropy. However, as a non-convex function, it has a large number of local minima, andits undifferentiable attribute makes it impossible to use backpropagation, a method widely used in training current state-of-the-art neural networks. When zero-one loss is applied to deep neural networks, the entire training process becomes challenging. On the other hand, a massive non-unique solution probably also brings different decision boundaries when optimizing zero-one loss, making it possible to fight against transferable adversarial examples, which is a common weakness in deep learning …

The Interplay Of The Physical Landscape And Social Dynamics In Shaping Movement Of African Savanna Elephants (Loxodonta Africana), Maggie Wisniewska

Dissertations

Free ranging African savanna elephants (Loxodonta africana) are increasingly impacted by human-induced habitat loss and poaching for ivory. Because elephants live in tightly knit groups, this combination of threats not only reduces the size of their populations but also degrades their social interactions. Long-term relationships with socially competent individuals, such as experienced seniors, benefit the ability of other group members to access limiting resources and avoid danger. Understanding how anthropogenic pressure may affect persistence of elephant populations is important, because elephants are an economically important keystone species. This doctoral thesis characterizes how individual elephants influence the movement of their social …

Modeling Dewetting, Demixing, And Thermal Effects In Nanoscale Metal Films, Ryan Howard Allaire

Dissertations

Thin film dynamics, particularly on the nanoscale, is a topic of extensive interest. The process by which thin liquids evolve is far from trivial and can lead to dewetting and drop formation. Understanding this process involves not only resolving the fluid mechanical aspects of the problem, but also requires the coupling of other physical processes, including liquid-solid interactions, thermal transport, and dependence of material parameters on temperature and material composition. The focus of this dissertation is on the mathematical modeling and simulation of nanoscale liquid metal films, which are deposited on thermally conductive substrates, liquefied by laser heating, and subsequently …
