Using Enamel Matrix Derivative To Improve Treatment Efficacy In Periodontal Furcation Defects, Reza Masaeli, Kavosh Zandsalimi, Zahra Lotfi, Lobat Tayebi

School of Dentistry Faculty Research and Publications

Purpose

Furcations are complicated periodontal defects. Untreated furcations lead to loss of the involved teeth and supporting tissues. It has been demonstrated that regenerative biomaterials are beneficial in reconstruction of the bone surrounding furcation‐affected teeth. These biomaterials range from bone grafts and nonresorbable/resorbable barrier membranes to biologics that are able to trigger inactive regenerative processes in periodontal tissues. Selection of appropriate material(s) to treat furcations is challenging. The aim of this article is to provide a comparative outlook on different biomaterials applicable in regeneration of furcations with a focus on enamel matrix derivative (EMD).

Ready For The Robot: Bovines In The Integrated Circuit, Scout Calvert

University of Nebraska-Lincoln Libraries: Faculty Publications

Situating cows as co-laborers in global technology sectors, “Ready for the Robot” explores the predicament of cows working as robot operators, information workers, and data producers. The data cows produce shape the conditions in which they work, including their own bodies, as statistical evaluations of cattle abstract profitable traits and warp their connection to breed. Milking robots are posited as providing freedom to dairy cows, but this is far from guaranteed. Rather, cow bodies are programmed to fit the limitations of the robot and the routines of the automated farm, coding that breaches categories of breed. Drawing on Donna Haraway’s …

Measurement And Modeling Of The Spatiotemporal Dynamics Of Beach Surface Moisture Content, Phillip P. Schmutz, Steven L. Namikas

Faculty Publications

The spatiotemporal dynamics of surface moisture exert a significant influence on the operation of aeolian transport systems at many beaches. However, we currently lack the detailed understanding of variability in surface moisture required to incorporate it into aeolian models. This problem is addressed here through direct measurements and simulation modeling of beach surface moisture over a twelve-day period, and through quantification of the relative contributions of evaporation, condensation and groundwater inputs to surface moisture. It was found that the beach surface can be characterized spatially in terms of three moisture zones: a consistently dry zone (40%). The relative influence of …

Developmental Chromatin Restriction Of Pro‐Growth Gene Networks Acts As An Epigenetic Barrier To Axon Regeneration In Cortical Neurons, Ishwariya Venkatesh, Vatsal Mehra, Zimei Wang, Ben Califf, Murray G. Blackmore

Biomedical Sciences Faculty Research and Publications

Axon regeneration in the central nervous system is prevented in part by a developmental decline in the intrinsic regenerative ability of maturing neurons. This loss of axon growth ability likely reflects widespread changes in gene expression, but the mechanisms that drive this shift remain unclear. Chromatin accessibility has emerged as a key regulatory mechanism in other cellular contexts, raising the possibility that chromatin structure may contribute to the age‐dependent loss of regenerative potential. Here we establish an integrated bioinformatic pipeline that combines analysis of developmentally dynamic gene networks with transcription factor regulation and genome‐wide maps of chromatin accessibility. When applied …

Perceptions Of The Achievement Gap As Experienced Among Academically Proficient To High-Achieving African American Adolescents In The Rural Southeastern United States: A Phenomenological Study, Tony Antonio Dominic Roberts

Doctoral Dissertations and Projects

The purpose of this transcendental phenomenological study was to describe how the achievement gap is perceived as a lived experience by African American adolescents in a southeastern United States school district. The perception of the achievement gap as a lived experience among African American adolescents is generally defined as the meaning this group ascribes to their lived experience in the academic achievement gap. The theory guiding this study was Lev Vygotsky’s sociocultural theory. Vygotsky theorized that sociocultural learning precedes cognitive development; therefore, African American adolescents’ sociocultural awareness of the gap, or the meaning or lack of definition in perceptions of …

Elucidating A Role For The Cytoplasmic Domain In The Mycobacterium Tuberculosis Mechanosensitive Channel Of Large Conductance, Nadia Herrera, Grigory Maksaev, Elizabeth S. Haswell, Douglas Rees

Biology Faculty Research

Microbial survival in dynamic environments requires the ability to successfully respond to abrupt changes in osmolarity. The mechanosensitive channel of large conductance (MscL) is a ubiquitous channel that facilitates the survival of bacteria and archaea under severe osmotic downshock conditions by relieving excess turgor pressure in response to increased membrane tension. A prominent structural feature of MscL, the cytoplasmic C-terminal domain, has been suggested to infuence channel assembly and function. In this report, we describe the X-ray crystal structure and electrophysiological properties of a C-terminal domain truncation of the Mycobacterium tuberculosis MscL (MtMscLΔC). A crystal structure of MtMscLΔC solubilized in …

Polypharmacology Or Promiscuity? Structural Interactions Of Resveratrol With Its Bandwagon Of Targets, Uzma Saqib, Tanya T. Kelley, Siva K. Panguluri, Dongfang Liu, Rajkumar Savai, Mirza S. Baig, Stephan C. Schürer

Pharmacy Faculty Publications

Resveratrol (3, 4′, 5-trihydroxy-trans-stilbene) is a natural phytoalexin found in grapes and has long been thought to be the answer to the “French Paradox.” There is no shortage of preclinical and clinical studies investigating the broad therapeutic activity of resveratrol. However, in spite of many comprehensive reviews published on the bioactivity of resveratrol, there has yet to be a report focused on the variety and complexity of its structural binding properties, and its multi-targeted role. An improved understanding of disease mechanisms at the systems level has enabled targeted polypharmacology to mature into a rational drug discovery approach. Unlike traditional hit-to-lead …

Developmental Changes In The Feedback Related Negativity From 8 To 14 Years, Yael Arbel, Kayleigh N. Mccarty, Mark S. Goldman, Emanuel Donchin, Ty Brumback

Psychology Faculty Publications

The study examined age related changes in the magnitude of the Feedback Related Negativity (FRN) in 8–14 year old children performing a variation of a Go/No-Go task. Participants were presented with four stimuli and tasked with mapping each of them either to a response or to a “no response” by trial and error guided by feedback. Feedback was valid for two stimuli (Go and No-Go) and invalid (.5 positive; .5 negative feedback) for the other two stimuli. The amplitude of the FRN was evaluated as a function of age separately for Go and No-Go …

Gender Segregation: What Does Dividing Space Across Gender Mean?, Mikayla Hope Starr

Architecture Thesis Prep

A Utopia is an idea of an ideal form of society that rethinks current power structures and dynamics at play in the world and subverts them. In proposing a new perfect society, one is critiquing the current society and questioning what can and should be done to improve the status quo. To start creating a Utopia, designers must first consider what faults exist in the world that they wish to remove or improve.

In this Utopia, the focus will be on equality for all gender identities, through spatial design. The specific elements being studied are those spaces clearly delineated on …

When Law Calls, Does Science Answer? A Survey Of Distinguished Scientists & Engineers, Shari Seidman Diamond, Richard O. Lempert

Articles

Sound legal decision-making frequently requires the assistance of scientists and engineers. The survey we conducted with the cooperation of the American Academy examines the views of the legal system held by some of the nation’s most distinguished scientists and engineers, what motivates them to participate or to refuse to assist in lawsuits when asked, and their assessment of their experiences when they do participate. The survey reveals that a majority of the responding scientists and engineers will agree to participate when asked, and when they turn down requests, the most common reasons are lack of time and absence of relevant …

Correlates Of Rate Heterogeneity In Avian Ecomorphological Traits, A. M. Chira, C. R. Cooney, Jen A. Bright, E. J. R. Capp, E. C. Hughes, C. J. A. Moody, L. O. Nouri, Z. K. Varley, G. H. Thomas

School of Geosciences Faculty and Staff Publications

Heterogeneity in rates of trait evolution is widespread, but it remains unclear which processes drive fast and slow character divergence across global radiations. Here, we test multiple hypotheses for explaining rate variation in an ecomorphological trait (beak shape) across a globally distributed group (birds). We find low support that variation in evolutionary rates of species is correlated with life history, environmental mutagenic factors, range size, number of competitors, or living on islands. Indeed, after controlling for the negative effect of species' age, 80% of variation in species‐specific evolutionary rates remains unexplained. At the clade level, high evolutionary rates are associated …

The Psychological Importance Of Forensic Identification To Families Of Victims Of Human Rights Violations, Emma S. Thoms

Student Publications

No one knows how many people are missing in the world. Among cases involving kidnapping, human trafficking, and armed conflicts, even the most scrutinous efforts can never verify the sheer number of missing persons. This mystery is especially true for armed conflicts and human rights abuses as “the reluctance of most states to deal honestly and effectively with this issue” keeps the number unknown (“Missing”). Sadly, a great deal of missing persons are not only missing, but dead and unidentified, often as a result of armed conflicts like genocide, which uses mass graves. Once the mass graves are unearthed, specially …

Immune Checkpoints In Cancer Treatment, Matthew A. Cherubino

Student Publications

Despite the human immune system, cancer thrives in an extremely hostile environment. Cancer is the second most common cause of death in the U.S. with about 600,000 deaths every year, and cancer is expected to surpass heart disease as the most common cause of death in the U.S. Immune checkpoint inhibitors are a novel and promising therapeutic for treating cancer in its late stages.

How The Misunderstanding That Heroin Addiction Is A Choice And The Stigma Surrounding Medication-Assisted Treatment Leads To More Overdose Deaths, Margaret M. Drew

Student Publications

Heroin is an opioid that commonly appears as white or brown powder. Eventually a person can become physically dependent on heroin, meaning the body begins to expect the drug. A sudden withdrawal from the drug can cause intense symptoms such as vomiting, muscle pain, and cravings, often leading to relapse (Shannon, p. 172). Although the initial decision to try heroin may be up to the addict, due to the dependence one develops when using heroin, addiction eventually morphs into an involuntary compulsion. There are many factors out of an individual’s control that influence their likelihood of trying heroin and becoming …

Nature Or Nurture? The Concentration Of African Americans In Specific Sports, Eric J. Klimowicz

Student Publications

The prevalence of African Americans in certain American professional sports is certainly evident. Their prevalence is particularly pertinent and commonly associated with sports such as basketball, football, and track. The percentage of the players in the National Basketball AssociatIon (NBA) that were African American in the 2017-2018 season was 73.9% (Lapchik, 2018). Additionally, the percentage of players that were African American in the National Football League (NFL) during the 2016-2017 season was 69.7% (Lapchik, 2018). These statistics however differ from proportions of African Americans representing these respective sports at the Division I college level. The percentage of African Americans at …
