Amino Acid-Dependent Stability Of The Acyl Linkage In Aminoacyl-Trna., Jacob R Peacock, Ryan R Walvoord, Angela Y Chang, Marisa C Kozlowski, Ya-Ming Hou

Department of Biochemistry and Molecular Biology Faculty Papers

Aminoacyl-tRNAs are the biologically active substrates for peptide bond formation in protein synthesis. The stability of the acyl linkage in each aminoacyl-tRNA, formed through an ester bond that connects the amino acid carboxyl group with the tRNA terminal 3'-OH group, is thus important. While the ester linkage is the same for all aminoacyl-tRNAs, the stability of each is not well characterized, thus limiting insight into the fundamental process of peptide bond formation. Here, we show, by analysis of the half-lives of 12 of the 22 natural aminoacyl-tRNAs used in peptide bond formation, that the stability of the acyl linkage is …

Forestry Professionals And Extension Educators Vs. Climate Change: Implications For Cooperative Extension Programming, Christopher Jones, Melanie Lenart

Journal of Extension

Extension educators seeking to integrate climate science into programming must respect different perceptions on climate change. We surveyed forestland managers and owners, researchers, and Extension educators nationally to compare perceptions about climate change adaptation and mitigation management in forests (n=576). Despite differences in perception that climate change is anthropogenic, we found the professional groups were often statistically similar in supporting or rejecting specific actions and receptive to learning more about a variety of forest adaptation and mitigation practices. Our findings support a role for Extension in addressing climate change and indicate areas of common ground that can minimize contention.

Hydrilla Infestations In Florida Freshwater Bodies: How Results From A Management Needs Assessment Survey Helped Develop Suitable Information Delivery Platforms, Jennifer L. Gillett-Kaufman, Verena-Ulrike Lietze, Joan P. Bradshaw, Kenneth T. Gioeli

Journal of Extension

Hydrilla is an invasive aquatic plant that is expensive to control and exhibits increasing resistance to commonly used herbicides. Alternative control tactics for implementation in novel integrated management strategies are being investigated, but information needs to be delivered to stakeholders so new tactics can be adopted and used. Here, we report results from a low-cost, Web-based survey that assessed stakeholder access to hydrilla management information in Florida. We highlight the general benefits of needs assessment surveys for project development and exemplify how results from such surveys can be used by Extension professionals to tailor their information platforms to stakeholder-preferred outlets.

The extended foster care system was implemented to support and provide services to young adults passed the age of 18, to provide them a couple more years to obtain stability in their lives. In order to participate in extended foster care, they have to meet a few requirements, and sometimes this is the minimum level of commitment and effort they contribute. These requirements include: …

A Spanish Version Of The Children's Sleep Habits Questionnaire (Cshq), Duvia Lara Ledesma

Electronic Theses, Projects, and Dissertations

This study was done to validate a widely used parent questionnaire that assesses sleep problems in children ages 4‑10. To date, no Spanish‑language sleep questionnaire is available for the Spanish‑speaking population. Research has found that sleep problems affect both typically developing children and children with developmental disabilities, potentially detracting from their quality of life. Spanish is the second most frequently spoken language in the United States, so it is of high importance to make available a Spanish‑language sleep questionnaire. The Children’s Sleep Habits Questionnaire (CSHQ) was chosen to be translated. The norming data for validation of the CSHQ‑S included 151 …

Cytokine Control Of Glioma Adhesion And Migration, Negin Baghdadchi

Electronic Theses, Projects, and Dissertations

Glioblastoma multiforme (GBM) is the most lethal primary central nervous system tumor, with median survival after diagnosis of less than 12 months because dissemination into the brain parenchyma limits the long-term effectiveness of surgical resection, and because GBM cells are resistant to radiation and chemotherapy. This sad dismal prognosis for patients with GBM emphasizes the need for greater understand of the fundamental biology of the disease.

Invasion is one of the major causes of treatment failure and death from glioma, because disseminated tumor cells provide the seeds for tumor recurrence. Inflammation is increasingly recognized as an important component of invasion. …

Coal, Global Warming, And The Clean Air Act, Terry L. Stewart

Electronic Theses, Projects, and Dissertations

In the early 1990s many scientists claimed that there was a scientific consensus that the anthropogenic production of greenhouse gases was causing global warming. Carbon dioxide is produced in far greater quantities than other greenhouse gases. Over 80 percent of the carbon dioxide produced in the United States comes from coal-fired power plants. If global warming is a threat to the welfare and survival of future generations, the United States, as one of the greatest producers of greenhouse gases,has an obligation to reduce its production of these gases.

In order to determine the most effective way to reduce the production …

Cyberterrorism After Stuxnet, Thomas M. Chen Dr.

Books, Monographs & Collaborative Studies

View the Executive Summary

The discovery of STUXNET was a recent milestone in the arena of cyber security because it was the first malware designed to cause real world damage to industrial control systems. It demonstrated that a sufficiently determined adversary might be able to cause physical damage to U.S. critical infrastructure through a cyberattack. This monograph asks if STUXNET has had an effect on cyberterrorism in terms of motive, means, and opportunity. It is argued that terrorists have ample motive, opportunity, and modest means, which raises the question of why a major cyberattack has not happened yet. The lack …

Abstract

Background

Cystic echinococcosis (CE) is a globally distributed cestode zoonosis that causes hepatic cysts. Although Echinococcus granulosus sensu stricto (s.s.) is the major causative agent of CE worldwide, recent molecular epidemiological studies have revealed that E. canadensis is common in countries where camels are present. One such country is Mongolia.

Methodology/Principal Findings

Forty-three human hepatic CE cases that were confirmed histopathologically at the National Center of Pathology (NCP) in Ulaanbaatar (UB) were identified by analysis of mitochondrial cox1 gene as being caused by either E. canadensis (n = 31, 72.1%) or E. granulosus s.s. ( …

Reconsidering Childfreedom: A Feminist Exploration Of Discursive Identity Construction In Childfree Livejournal Communities, Julia Moore

Department of Communication Studies: Faculty Publications

This article employs participant definitional analysis, sensitized with feminist poststructuralism and critical ethnography, to understand three identity construction processes that members of childfree LiveJournal communities participate in: (a) naming childfreedom, (b) negotiating childfreedom, and (c) enacting childfreedom. I argue that childfree identities are contested and sometimes activist. Ultimately, I call for scholars to reconsider the definition of childfree to account for the complex and nuanced identities constructed by individuals who identify as such.

Synthesis Of The Effect Of Fire On Lesser Prairie‐Chickens, Eric Thacker, Dirac L. Twidwell Jr

Department of Agronomy and Horticulture: Faculty Publications

In this synthesis, we reviewed the scientific literature pertaining to the effects of fire on lesser prairie‐chickens and their habitat. Overall, research is generally lacking that directly assesses relationships among fire, both as a regime and a discrete event, to its effect on lesser prairie‐chicken behavior and habitat value. Yet, research has quantified the effects of fire on vegetation throughout the distribution of the lesser prairie‐chicken, which has been linked to known metrics of habitat value and broad landscape‐level habitat requirements.

To summarize the literature, lesser prairie‐chickens require broad landscapes of fire‐dependent grass‐shrub vegetation. Changes in the eco‐evolutionary fire regime …

Developing Defined And Scalable 3d Culture Systems For Culturing Human Pluripotent Stem Cells At High Densities, Yuguo Lei, Daeun Jeong, Jifang Xiao, David V. Schaffer

Department of Chemical and Biomolecular Engineering: Faculty Publications

Human pluripotent stem cells (hPSCs)—including embryonic stem cells (hESCs) and induced pluripotent stem cells (hiPSCs)—are very promising candidates for cell therapies, tissue engineering, high throughput pharmacology screens, and toxicity testing. These applications require large numbers of high quality cells; however, scalable production of human pluripotent stem cells and their derivatives at a high density and under well-defined conditions has been a challenge. We recently reported a simple, efficient, fully defined, scalable, and good manufacturing practice (GMP) compatible 3D culture system based on a thermoreversible hydrogel for hPSC expansion and differentiation. Here, we describe additional design rationale and characterization of this …

The Evolution Of Respiratory O2/No Reductases: An Out-Of-The-Phylogenetic-Box Perspective, Anne-Lise Ducluzeau, Barbara Schoepp-Cothenet, Robert Van Lis, Frauke Baymann, Michael J. Russell, Wilfgang Nitschke

Department of Biochemistry: Faculty Publications

Complex life on our planet crucially depends on strong redox disequilibria afforded by the almost ubiquitous presence of highly oxidizing molecular oxygen. However, the history of O₂-levels in the atmosphere is complex and prior to the Great Oxidation Event some 2.3 billion years ago, the amount of O₂ in the biosphere is considered to have been extremely low as compared with present-day values. Therefore the evolutionary histories of life and of O₂-levels are likely intricately intertwined. The obvious biological proxy for inferring the impact of changing O₂-levels on life is the evolutionary history …

School of Biological Sciences: Faculty Publications

Kenya is a world leader in conservation and host to one of the most diverse array of mammals on the planet. As a focus of scientific attention, it is important to be able to assess not only the current state of Kenya’s mammal communities, but also how they have changed over anthropogenic timescales. Comprehensive lists of mammal species from known areas are essential for this goal, and these also provide comparative baselines for assessing changes in mammalian diversity in the future and in the fossil record. Though there is considerable literature available for mammals inhabiting Kenyan protected areas (National Parks …

Dermatological Manifestations Of Hepatitis C Virus Infection In Saudi Arabia, Mona R. Halawani

Saudi Medical Journal

The Saudi Ministry of Health data indicates that almost 32% of viral hepatitis cases were caused by hepatitis C virus (HCV). It has been widely reported that chronic HCV infection is associated with and may trigger or exacerbate many skin manifestations in 20-40% of patients visiting dermatologists. The most commonly encountered dermatological manifestations of HCV infection globally include mixed cryoglobulinemia, porphyria cutanea tarda, cutaneous and/or oral lichen planus, urticaria, pruritus, thrombocytopenic purpura, and psoriasis.
