Global Seawater Redox Trends During The Late Devonian Mass Extinction Detected Using U Isotopes Of Marine Carbonates, David Allen White

Earth and Planetary Sciences ETDs

The Late Devonian extinction ranks as one of the ‘big five’ Phanerozoic extinctions affecting up to 80% of marine species and occurred during five distinct pulses spanning /or widespread marine anoxia. We test the marine anoxia hypothesis by analyzing uranium isotopes (δ²³⁸U) across a ~7 My interval of well-dated Upper Devonian marine carbonates from the Devil’s Gate Limestone in Nevada, USA.

The measured δ²³⁸U curve shows no co-variation with local anoxic facies, water-depth dependent facies changes, redox-sensitive metals, TOC, or diagnostic elemental ratios indicating the δ²³⁸U curve was not controlled by local depositional or …

Covariant Risk And Nutrient Credit Training, Brian Sawers

Maryland Law Review Online

Every summer, a dead zone is created in the Chesapeake Bay. The dead zone is created by too much of a good thing: nutrients, especially nitrogen and phosphorus. The largest source of excess nutrients in the Chesapeake is agriculture; manure and artificial fertilizers are washed into streams that eventually reach the bay. In the bay, nitrogen and phosphorus create an algae bloom, which consumes all the dissolved oxygen. Some fish escape, but other creatures expire in this dead sea within the Chesapeake Bay.

To reduce the excess nutrients reaching the bay, several states are experimenting with nutrient credit trading. A …

Disability At Work: Libraries, Built To Exclude, Jessica Schomberg

Library Services Publications

My goal in writing this chapter is to use critical disability theory grounded in my lived experience to offer some possibilities for improving the working conditions of library employees with disabilities. I begin by providing an overview of some mainstream and critical perspectives on disability. Next, I offer my own insights into being a disabled librarian by taking an intersectional approach to the construction of power. I conclude the chapter by suggesting some ways to bring theory and practice together to make the workplace more inclusive of people. Throughout the chapter, I share some of my experiences as a person …

Word-List Intrusion Errors Predict Progression To Mild Cognitive Impairment, Kelsey R Thomas, Joel Eppig, Emily C Edmonds, Diane M Jacobs, David J Libon, Rhoda Au, David P Salmon, Mark W Bondi, Alzheimer’S Disease Neuroimaging Initiative

Rowan-Virtua School of Osteopathic Medicine Departmental Research

OBJECTIVE: Preclinical Alzheimer's disease (AD) defined by a positive AD biomarker in the presence of normal cognition is presumed to precede mild cognitive impairment (MCI). Subtle cognitive deficits and cognitive inefficiencies in preclinical AD may be detected through process and error scores on neuropsychological tests in those at risk for progression to MCI.

METHOD: Cognitively normal participants (n = 525) from the Alzheimer's Disease Neuroimaging Initiative were followed for up to 5 years and classified as either stable normal (n = 305) or progressed to MCI (n = 220). Cox regressions were used to determine whether baseline process scores on …

A Complex Molecular Switch Directs Stress-Induced Cyclin C Nuclear Release Through Scfgrr1-Mediated Degradation Of Med13., David C Stieg, Stephen D Willis, Vidyaramanan Ganesan, Kai Li Ong, Joseph Scuorzo, Mia Song, Julianne Grose, Randy Strich, Katrina F Cooper

Rowan-Virtua School of Osteopathic Medicine Departmental Research

In response to oxidative stress, cells decide whether to mount a survival or cell death response. The conserved cyclin C and its kinase partner Cdk8 play a key role in this decision. Both are members of the Cdk8 kinase module, which, with Med12 and Med13, associate with the core mediator complex of RNA polymerase II. In

Development Of Body Emotion Perception In Infancy_ From Discrimination To Recognition.Pdf, Alison Heck, Alyson Chroust, Hannah White, Rachel Jubran, Ramesh Bhatt

Psychology Faculty Works

Research suggests that infants progress from discrimination to recognition of emotions in faces during the first half year of life. It is whether the perception of emotions from bodies develops in a similar manner. In the current study, when presented with happy and angry body videos and voices, 5-month-olds looked longer at the matching video when they were presented upright but not when they were inverted. In contrast, 3.5-month-olds failed to match even with upright videos. Thus, 5-month-olds but not 3.5-month-olds exhibited evidence of recognition of emotions from bodies by demonstrating intermodal matching. In a subsequent experiment, younger infants did …

Blake, Ross Breckenridge, Paul R Riley, Pier D Lambiase, Perry M Elliott, Lucie Clapp, Andrew Tinker, David P. Hill

Faculty Research 2018

BACKGROUND: A systems biology approach to cardiac physiology requires a comprehensive representation of how coordinated processes operate in the heart, as well as the ability to interpret relevant transcriptomic and proteomic experiments. The Gene Ontology (GO) Consortium provides structured, controlled vocabularies of biological terms that can be used to summarize and analyze functional knowledge for gene products.

METHODS AND RESULTS: In this study, we created a computational resource to facilitate genetic studies of cardiac physiology by integrating literature curation with attention to an improved and expanded ontological representation of heart processes in the Gene Ontology. As a result, the Gene …

Metallic Mxenes: A New Family Of Materials For Flexible Triboelectric Nanogenerators, Yongchang Dong, Sai Sunil Kumar Mallineni, Kathleen Maleski, Herbert Behlow, Vadym N. Mochalin, Apparao M. Rao, Yury Gogosti, Ramakrishna Podila

Publications

Wearable and flexible electronics warrant the development of self-powered devices to circumvent the limitations imposed by traditional energy storage devices. Triboelectric nanogenerators (TENGs) that convert waste mechanical energy from human motion into electric power offer a solution. Highly electronegative and conducting TENG materials that support the generation of both large potential differences and high currents are imperative for effectively harvesting electric power from human muscle movements. Here, we demonstrate that two-dimensional MXenes (e.g., titanium carbide Ti3C2Tx, where Tx stands for surface functional groups such as -O, -OH, and -F) are a family of electrically conducting materials that are triboelectrically more …

© 2018 Taylor and Francis Group, LLC. In yeast, Tom22, the central component of the TOMM (translocase of outer mitochondrial membrane) receptor complex, is responsible for the recognition and translocation of synthesized mitochondrial precursor proteins, and its protein kinase CK2-dependent phosphorylation is mandatory for TOMM complex biogenesis and proper mitochondrial protein import. In mammals, the biological function of protein kinase CSNK2/CK2 remains vastly elusive and it is unknown whether CSNK2-dependent phosphorylation of TOMM protein subunits has a similar role as that in yeast. To address this issue, we used a skeletal muscle-specific Csnk2b/Ck2β-conditional knockout (cKO) mouse model. Phenotypically, these skeletal …

The Effect Of Cold Acclimation On Active Ion Transport In Cricket Ionoregulatory Tissues., Lauren E Des Marteaux, Soheila Khazraeenia, Gil Y Yerushalmi, Andrew Donini, Natalia G Li, Brent J Sinclair

Biology Publications

Cold-acclimated insects defend ion and water transport function during cold exposure. We hypothesized that this is achieved via enhanced active transport. The Malpighian tubules and rectum are likely targets for such transport modifications, and recent transcriptomic studies indicate shifts in Na+-K+ ATPase (NKA) and V-ATPase expression in these tissues following cold acclimation. Here we quantify the effect of cold acclimation (one week at 12 °C) on active transport in the ionoregulatory organs of adult Gryllus pennsylvanicus field crickets. We compared primary urine production of warm- and cold-acclimated crickets in excised Malpighian tubules via Ramsay assay at a range of temperatures …

Maternal Egg Hormones In The Mating Context: The Effect Of Pair Personality, S. Ruuskanen, T. G. G. Groothuis, Alexander T. Baugh, S. V. Schaper, B. De Vries, K. Van Oers

Biology Faculty Works

1. Animal personality traits emerge developmentally from the interaction of genetic and early environmental factors. Maternal hormones, such as androgens (testosterone, T and androstenedione, A4), transferred to embryos and egg yolks may simultaneously organize multiple behavioural and physiological traits. Although previous studies demonstrated an association between the mother's personality and yolk androgen levels, the independent effects of the male partner's personality and pair combination remains unknown. 2. We test this association using an ecological model species for personality research, the great tit (Parus major) using multiple approaches: (1) a wild population, (2) a randomly mated captive population and (3) an …

Molecular Dynamics Of Palmitic Acid And Lead Palmitate In Cross-Linked Linseed Oil Films: Implications From Deuterium Magnetic Resonance For Lead Soap Formation In Traditional Oil Paintings, Jaclyn Catalano, Anna Murphy, Yao Yao, Nicholas Zumbulyadis, Silvia A. Centeno, Cecil Dybowski

Department of Chemistry and Biochemistry Faculty Scholarship and Creative Works

Many oil paintings, dating from the 15th century to the present, are affected by the formation of heavy-metal carboxylates (soaps) that alter the structural integrity and appearance of the works. Through transport phenomena not yet understood, free fatty acids formed from oils used as binders migrate through the paint film and react with heavy-metal ions that are constituents of pigments and/or driers, forming metal carboxylates. The local molecular dynamics of fatty acids and metal carboxylates are factors influencing material transport in these systems. We report temperature-dependent 2H NMR spectra of palmitic acid and lead palmitate as pure materials, in cross-linked …

Inactivation Of Trpm7 Kinase In Mice Results In Enlarged Spleens, Reduced T-Cell Proliferation And Diminished Store-Operated Calcium Entry, Pavani Beesetty, Krystyna Blanka Wieczerzak, Jennifer Gibson, Taku Kaitsuka, Charles Tuan Luu, Masayuki Matsushita, J. Ashot Kozak

Neuroscience, Cell Biology & Physiology Faculty Publications

T lymphocytes enlarge (blast) and proliferate in response to antigens in a multistep program that involves obligatory cytosolic calcium elevations. Store-operated calcium entry (SOCE) pathway is the primary source of Ca2+ in these cells. Here, we describe a novel modulator of blastogenesis, proliferation and SOCE: the TRPM7 channel kinase. TRPM7 kinase-dead (KD) K1646R knock-in mice exhibited splenomegaly and impaired blastogenic responses elicited by PMA/ionomycin or anti-CD3/CD28 antibodies. Splenic T-cell proliferation in vitro was weaker in the mutant compared to wildtype littermates. TRPM7 current magnitudes in WT and KD mouse T cells were, however, similar. We tested the dependence of T-cell …

Effects Of Agriculture, Riley Brutto '20, Maddy Chow '20

Due to a lack of education among their population, many Brazilians turn to agriculture as a way to provide for themselves and their families. Additionally, low labor costs draw in large commercial companies that establish business in these developing worlds. However, to obtain farmland in the first place, deforestation has become a common practice, where thousands of miles of lush jungles are cleared away for agricultural practices. According to NASA imaging, 224,000 square miles of rainforest have been cleared in the Amazon. If left unchecked, the drastic consequences could harm not only the countries practicing deforestation, but the entire earth.
