Congenital Zika Virus Infection In Immunocompetent Mice Causes Postnatal Growth Impediment And Neurobehavioral Deficits, Amber M. Paul, Dhiraj Acharya, Biswas Neupane, E. Ashley Thompson, Gabriel Gonzalez-Fernandez, Katherine M. Copeland

Publications

A small percentage of babies born to Zika virus (ZIKV)-infected mothers' manifest severe defects at birth, including microcephaly. Among those who appeared healthy at birth, there are increasing reports of postnatal growth or developmental defects. However, the impact of congenital ZIKV infection in postnatal development is poorly understood. Here, we report that a mild congenital ZIKV-infection in pups born to immunocompetent pregnant mice did not display apparent defects at birth, but manifested postnatal growth impediments and neurobehavioral deficits, which include reduced locomotor and cognitive deficits that persisted into adulthood. We found that the brains of these pups were smaller, had …

Offspring Dependence On Parental Care And The Role Of Parental Transfer Of Oral Fluids In Burying Beetles, Scott K. Sakaluk, Alexandra Capodeanu-Nägler, Madlen A. Prang, Stephen T. Trumbo, Heiko Vogel, Anne-Katrin Eggert, Sandra Steiger

Faculty Publications – Biological Sciences

Background

Immature stages of many animals can forage and feed on their own, whereas others depend on their parents’ assistance to obtain or process food. But how does such dependency evolve, and which offspring and parental traits are involved? Burying beetles (Nicrophorus) provide extensive biparental care, including food provisioning to their offspring. Interestingly, there is substantial variation in the reliance of offspring on post-hatching care among species. Here, we examine the proximate mechanisms underlying offspring dependence, focusing on the larvae of N. orbicollis, which are not able to survive in the absence of parents. We specifically asked …

Green Burials: The Deinstitutionalization Of Death, A A. Bouverette 3906173

The Hilltop Review

Abstract

Methods for preparing and burying the dead vary widely across time and cultures, but an enduring theme persists in ritualistic deposition. Some forms of disposal include inhumation, cremation, entombment, sea submersion and methods of exposure (Spellman, 2014). For many cultures, an exposed corpse or one that had not been given ritualized funeral rites was viewed as improper or neglectful. Exposed or rotting bodies is also associated with disease and illness (Feagan. 2007).

The transition from natural burial to preservative practices is a recent invention created in response to mass death during a wartime period (Stowe, Schmidt & Green, 2001). …

A Cross-Cultural Approach To Environmental And Peace Work: Wangari Maathai’S Use Of Mottainai In Kenya, Eddah Mutua, Kikuko Omori

The Journal of Social Encounters

Protecting the environment and nurturing peace are global concerns requiring scholarly attention across and within cultures.

Gain-Of-Function Experiments With Bacteriophage Lambda Uncover Residues Under Diversifying Selection In Nature, Rohan Maddamsetti, Daniel T. Johnson, Stephanie J. Spielman, Katherine L. Petrie, Debora S. Marks, Justin R. Meyer

College of Science & Mathematics Departmental Research

Viral gain‐of‐function mutations frequently evolve during laboratory experiments. Whether the specific mutations that evolve in the lab also evolve in nature and whether they have the same impact on evolution in the real world is unknown. We studied a model virus, bacteriophage λ, that repeatedly evolves to exploit a new host receptor under typical laboratory conditions. Here, we demonstrate that two residues of λ’s J protein are required for the new function. In natural λ variants, these amino acid sites are highly diverse and evolve at high rates. Insertions and deletions at these locations are associated with phylogenetic patterns indicative …

App21 Transgenic Rats Develop Age-Dependent Cognitive Impairment And Microglia Accumulation Within White Matter Tracts, Nina Weishaupt, Qingfan Liu, Sheojung Shin, Ramandeep Singh, Yuksel Agca, Cansu Agca, Vladimir Hachinski, Shawn Narain Whitehead

Anatomy and Cell Biology Publications

Background: Most of the animal models commonly used for preclinical research into Alzheimer's disease (AD) largely fail to address the pathophysiology, including the impact of known risk factors, of the widely diagnosed sporadic form of the disease. Here, we use a transgenic rat (APP21) that does not develop AD-like pathology spontaneously with age, but does develop pathology following vascular stress. To further the potential of this novel rat model as a much-needed pre-clinical animal model of sporadic AD, we characterize APP21 transgenic rats behaviorally and histologically up to 19 months of age. Methods: The open field test was used as …

The Price Of Sociality, John Thrasher

Philosophy Faculty Articles and Research

A review of Jonathan Birch's The Philosophy of Social Evolution, published by Oxford University Press.

Perspectives On Natural Philosophy, Stanley N. Salthe

Publications and Research

This paper presents a viewpoint on natural philosophy focusing on the organization of substance, as well as its changes as invited by the Second Law of thermodynamics. Modes of change are pointed to as definitive of levels of organization; these include physical, chemical, and biological modes of change. Conceptual uses of the subsumptive hierarchy format are employed throughout this paper. Developmental change in dissipative structures is examined in some detail, generating an argument for the use of final causality in studies of natural systems. Considerations of ‘internalism’ in science are presented along the way.

Trueness, Precision And Stability Of The Liaison 1-84 Parathyroid Hormone (Pth) Third-Generation Assay: Comparison To Existing Intact Pth Assays, Andre Valcour, Claudia Zierold, Frank A. Blocki, Douglas M. Hawkins, Kevin J. Martin, Sudhaker D. Rao, Fabrizio Bonelli

Endocrinology Articles

BACKGROUND: Over the past few decades, parathyroid hormone (PTH) immunoassays have progressed through successive generations resulting in increased specificity and accuracy for detecting circulating PTH. With the introduction of third-generation assays, in which the biologically active PTH(1-84) is specifically targeted, the PTH(7-84) and other fragments are not detected. The specific recognition of only PTH(1-84) whole molecule allows for more reliable standardization and calibration than with the existing assays.

METHODS: Samples from patients on hemodialysis or with primary hyperparathyroidism and apparently healthy subjects were examined in different collection matrices (EDTA plasma, unspun EDTA plasma and SST) stored for 0, 24 or …
