The “Big Six”: Hidden Emerging Foodborne Bacterial Pathogens, Mona G. Alharbi, Rashad R. Al-Hindi, Ahmed Esmael, Ibrahim A. Alotibi, Sheren A. Azhari, Mazen S. Alseghayer, Addisu D. Teklemariam

Nebraska Center for Virology: Faculty Publications

Non-O157 Shiga toxin-producing Escherichia coli (STEC) are emerging serogroups that often result in diseases ranging from diarrhea to severe hemorrhagic colitis in humans. The most common non-O157 STEC are O26, O45, O103, O111, O121, and O145. These serogroups are known by the name “big six” because they cause severe illness and death in humans and the United States Department of Agriculture declared these serogroups as food contaminants. The lack of fast and efficient diagnostic methods exacerbates the public impact of the disease caused by these serogroups. Numerous outbreaks have been reported globally and most of these outbreaks were caused by …

Undetectable Very-Low Frequency Sound Increases Dancing At A Live Concert, Daniel J. Cameron, Dobromir Dotov, Erica Flaten, Dan Bosnyak, Michael J. Hove, Laurel Trainor

Journal Articles

Does low frequency sound (bass) make people dance more? Music that makes people want to move tends to have more low frequency sound, and bass instruments typically provide the musical pulse that people dance to1. Low pitches confer advantages in perception and movement timing, and elicit stronger neural responses for timing compared to high pitches2, suggesting superior sensorimotor communication. Low frequency sound is processed via vibrotactile3 and vestibular4 (in addition to auditory) pathways, and stimulation of these non-auditory modalities in the context of music can increase ratings of groove (the pleasurable urge to move to music) …

Sex-Biased Differences In Infant Mortality And Life Expectancy At At Síi Túupentak, An Ancestral Ohlone Village In Central California (Ca. 540–145 Cal. Bp), Tammy Buonasera, Jelmer Eerkens, Brian Byrd, Laurel Engbring, Monica Arellano, Alan Leventhal, Glendon Parker

Human Biology Open Access Pre-Prints

Síi Túupentak (CA-SCA-565/H) is a late precontact ancestral Ohlone village and cemetery site in central California (ca. 540-145 cal. BP). Integration of proteomic, genomic, and osteological analyses provided highly confident biological sex estimates for remains of most individuals at this site (65 of 76) spanning all age groups—from perinatal infants to aged adults. The comprehensive nature of the data allowed us to generate sex-specific Kaplan-Meyer survivorship curves for this burial population of sedentary hunter-gatherers. As was common among societies pre-dating modern western medicine and antibiotics, infant mortality was high for both males and females. However, male infants (from birth to …

Exploring The Biomedical Applications Of Polyurethane-Based Foams, Films, And Hydrogels, Anand Utpal Vakil

Dissertations - ALL

Shape memory polymers (SMPs) are a class of smart materials that can be temporarily stored in a deformed shape and can actively recover their original shape upon exposure to an external stimulus, such as heat, magnetic field, moisture, pH, light, or electric field. The ability of SMPs to change shape when required can be used for a wide range of applications, especially in the case of minimally invasive biomedical applications. In this work, polyurethane-based SMPs were explored for their use in tissue engineering, drug delivery, and wound healing applications.

Leaf rust, caused by Puccinia triticina (Pt), constantly threatens durum (Triticum turgidum ssp. durum) and bread wheat (Triticum aestivum) production worldwide. A Pt race BBBQD detected in California in 2009 poses a potential threat to durum production in North America because resistance source to this race is rare in durum germplasm. To find new resistance sources, we assessed a panel of 180 cultivated emmer wheat (Triticum turgidum ssp. dicoccum) accessions for seedling resistance to BBBQD and for adult resistance to a mixture of durum-specific races BBBQJ, CCMSS, and MCDSS in the field, and genotyped …

Islands In The Mud: The South Texas Banks Provide Crucial Mesophotic Habitat For Coral Communities, Maria Bollinger, Keir J. Macartney, Erin E. Easton, David Hicks

School of Earth, Environmental, & Marine Sciences Faculty Publications

On the continental shelf off the coast of South Texas lie a series of natural hard-bottom structures (rocky outcrops and relic coral-algal reefs) known as the South Texas Banks (STB), which provide critical habitat for benthic organisms and pelagic fish. The depth of the banks, a persistent nepheloid layer, and strong currents have resulted in few studies that provide quantitative biodiversity data on the STB. Using a remotely operated vehicle (ROV), video surveys were conducted to quantitatively describe the mesophotic coral communities and assess habitat suitability of five STB: North Hospital, Hospital, Southern, Big Adam, and Mysterious Banks. Each of …

Radiation therapy (RT) to the chest increases the patients’ risk of cardiovascular disease (CVD). A complete understanding of the mechanisms by which RT induces CVD could lead to specific preventive, therapeutic approaches. It is becoming evident that both genotoxic chemotherapy agents and radiation induce mitochondrial dysfunction and cellular senescence. Notably, one of the common phenotypes observed in cancer survivors is accelerated senescence, and immunosenescence is closely related to both cancer risk and CVD development. Therefore, suppression of immunosenescence can be an ideal target to prevent cancer treatment-induced CVD. However, the mechanism(s) by which cancer treatments induce immunosenescence are incompletely characterized. …

The Relationship Among Maternal Characteristics, Maternal Dietary Self-Regulation, And The Dietary Intake And Body Weight Status Of Two To Five-Year-Old Children, Andrea Bushaw

Dissertations

Eating preferences and practices are established early in life, yet we have little knowledge about how mothers make food decisions on behalf of their children. These decisions, however, lay the foundation for their child's lifelong food preferences and eating behaviors. Almost one-third of all children in the U.S. are overweight or obese putting them at high risk for becoming an overweight or obese adult. To make a difference in the ongoing obesity epidemic, we must better understand the relationship among characteristics of the mother who controls the young child's access to food, food choices, and feeding practices. This knowledge will …

A qualitative multi-case study design was used to collect data from semi-structured interviews and on-site observations for four Saudi early childhood teachers in two Montessori classrooms in Saudi Arabia. The data were thematically analyzed manually and with NVivo software. The study results showed that the teachers encouraged children’s independence and freedom of choice in work time and during the classroom day, but limited their freedom during mini-lessons and circle …

Minecraft In Language Teacher Education: Acceptance And Integration In Practice, Kristen E. Fung

USF Tampa Graduate Theses and Dissertations

In today’s technological era, understanding if and how teachers’ acceptance and integration of technology evolves is critical to understanding their needs. Technology creates complicated demands on educators and research shows various factors may contribute to their limited success at integrating it (Bustos & Nussbaum, 2009). Research also shows that teachers’ perceptions and attitudes towards pedagogical innovations and information and communication technologies are prominent factors that impact adoption and integration (Tejedor & Muñoz-Repiso, 2006), and the perceptions teachers develop as pre-service teachers influence their classroom performance as in-service teachers (Moon et al., 2016). While research shows plentiful evidence of the educational …

Pi3k Isoform-Specific Regulation Of Leader And Follower Cell Function For Collective Migration And Proliferation In Response To Injury, Morgan D Basta, A. Menko, Janice L Walker

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

To ensure proper wound healing it is important to elucidate the signaling cues that coordinate leader and follower cell behavior to promote collective migration and proliferation for wound healing in response to injury. Using an ex vivo post-cataract surgery wound healing model we investigated the role of class I phosphatidylinositol-3-kinase (PI3K) isoforms in this process. Our findings revealed a specific role for p110α signaling independent of Akt for promoting the collective migration and proliferation of the epithelium for wound closure. In addition, we found an important role for p110α signaling in orchestrating proper polarized cytoskeletal organization within both leader and …

Defining Understudied Mechanisms Of Potassium Ion Flux In The Insect Nervous System, Rui Chen

LSU Doctoral Dissertations

To identify novel insecticide target sites that can address the evolution of insecticide resistance, our group has tested the insecticidal potential of two potassium flux pathways: potassium-chloride (K+/Cl−) cotransporter (KCC) and inward rectifier potassium (Kir) channels. GABAergic signaling is the cornerstone of fast synaptic inhibition for neural signaling in arthropods; thus, the γ-aminobutyric acid (GABA)-receptor-chloride-channel (GRCC) complex has been a longstanding target for insecticides. Despite the importance to neuronal homeostasis, the upstream mechanisms enabling GRCC function are poorly defined. The data presented in this dissertation provide strong support that KCC is an essential ion transport system for proper neural function …

School of Medicine Publications

Similar to previous pandemics, COVID-19 has been succeeded by well-documented postinfectious sequelae, including chronic fatigue, cough, shortness of breath, myalgia, and concentration difficulties, which may last 5 to 12 weeks or longer after the acute phase of illness. Both the psychological stress of SARS-CoV-2 infection and being diagnosed with COVID-19 can upregulate cortisol, a stress hormone that disrupts the efferocytosis effectors, macrophages, and natural killer cells, leading to the excessive accumulation of senescent cells and disruption of biological barriers. This has been well-established in cancer patients who often experience unrelenting fatigue as well as gut and blood– brain barrier dysfunction …

Observations Of The Mating Habits And Attack Pattern Of Trypodendron Retusum (Coleoptera: Curculionidae: Scolytinae) On Populus Grandidentata In Central Michigan, Richard Roeper, Daniel Dickerson, Paul Kurtzhals, Mark Bunce, Steven Brewer

The Great Lakes Entomologist

Trypodendron retusum Leconte attack pattern on Populus grandidentata Michx. (Big Tooth Aspen) was studied. Mating habits of males and females involved copulation at the entrance hole bored by the female. Attack (entrance )holes averaged 15.9 cm. apart and were found to be uniformly spaced on the bark surface. Attack density was greater on standing trees than wind-thrown trees. On standing trees attack density appeared to be a function of the height rather than the diameter of the tree.

Examining Resistance Of Asian, European, And North American Ash And Elm Species To The Emerald Ash Borer (Agrilus Planipennis) (Coleoptera: Buprestidae), Fredric Miller, Erin Mcmahan

The Great Lakes Entomologist

The emerald ash borer (EAB) (Agrilus planipennis Fairmaire) (Coleoptera: Buprestidae), native to East Asia and discovered in Michigan in 2002, has been a devastating pest of North American ash trees (Fraxinus spp.). Along with native ecosystems in Eastern North America, a large percentage of urban canopies in many North American cities consist of ash trees, and many of these areas have lost or risk losing these valuable trees. As part of a multi-faceted management strategy, it is important to develop and plant cultivars of ash with resistance to this damaging insect. Given that EAB is not considered a …

In the face of well-documented declines in multiple bumblebee species, it is important to accurately identify species and properly delineate species ranges. Here, we document the range of Bombus auricomus (Robertson) and B. nevadensis Cresson in Minnesota, with particular reference to the unexpected discovery of B. nevadensis in St. Paul. We clarify the relative ranges of these two species and provide additional information on how to reliably identify them in Minnesota using color patterns and morphology, including differences in male genitalia. Our results support the consensus that B. auricomus and B. nevadensis are distinct species. Community science records were integral …

Western Bean Cutworm (Lepidoptera: Noctuidae) Feeding And Development On Industrial Hemp In The Laboratory And Field, Christina D. Difonzo

The Great Lakes Entomologist

The western bean cutworm (Striacosta albicosta (Smith)) is a key pest of corn (Zea mays L.) and dry beans (Phaseolus vulgaris L.). This observational study demonstrates that in addition to these hosts, western bean cutworm readily feeds on industrial hemp (Cannabis sativa L.) and completes development on it under controlled laboratory conditions. In the laboratory, individual larvae were reared on a diet exclusively of hemp inflorescences; 57% survived to form prepupae and 15% emerged as moths. In the field, first instars were caged on hemp plants to investigate larval development in situ. After seven days, 82% …
