Assessing Infection Patterns In Chinese Mystery Snails From Wisconsin, Usa Using Field And Laboratory Approaches, Brittany Harried, Kyle Fischer, Kathryn E. Perez, Gregory J. Sandland

School of Integrative Biological & Chemical Sciences (Formerly Dept. of Biology)

The success of invasive species establishment in new habitats depends, in part, on interactions with other members of the invaded community. Cipangopaludina chinensis, the Chinese mystery snail (CMS), is an exotic, invasive snail in North America. Since its introduction in the 1890s, CMS have spread to a number of watersheds across the United States and parts of Canada. This invasion has generated questions about the snail’s capacity to serve as a host for parasites within local habitats, including parasites with conservation implications. To begin addressing these questions, we necropsied 147 wild-caught snails from 22 lakes across Wisconsin, finding only two …

What I Shoulda, Coulda, Woulda Learned In Science Class”: Black American Boys’ Narratives Of Past Science Teachers And Visions For A Culturally Responsive Science Teacher, Althea Hoard

Catalyst: A Social Justice Forum

This study follows three Black American, high school boys who participated in a “Men in STEM” book club in an urban school in New York City. Through narrative analysis, the boys describe their vision for a culturally responsive science teacher and connections are made between the boys’ experiences with science teachers and interest in STEM careers. 20 10^th grade Black American boys joined the “Men in STEM” book club and three participants are highlighted due to their differing interests in pursuing a STEM major in college. By triangulation of semi-structured interviews, two open-ended questionnaires, and researcher field notes, four …

Moving Toward A More Socially Just Classroom Through Teacher Preparation For Inclusion, Grace Blum, Megan Wilson, Yelena Patish

Catalyst: A Social Justice Forum

The current literature in teacher education for social justice fails to adequately address issues of disability within the equity discourse. In this paper, the authors advocate for a model of social justice teacher education that includes disability as part of the definition of marginalized groups by proposing the use of Response to Intervention (RTI) as a method for promoting inclusion into the social justice-oriented teacher preparation context.

Smilefinder: A Resampling-Based Approach To Evaluate Signatures Of Selection From Genome-Wide Sets Of Matching Allele Frequency Data In Two Or More Diploid Populations, Wilfred M. Guiblet, Kai Zhao, Stephen J. O'Brien, Steven E. Massey, Alfred L. Roca, T. K. Oleksyk

Biology Faculty Articles

Background: Adaptive alleles may rise in frequency as a consequence of positive selection, creating a pattern of decreased variation in the neighboring loci, known as a selective sweep. When the region containing this pattern is compared to another population with no history of selection, a rise in variance of allele frequencies between populations is observed. One challenge presented by large genome-wide datasets is the ability to differentiate between patterns that are remnants of natural selection from those expected to arise at random and/or as a consequence of selectively neutral demographic forces acting in the population.

Findings: SmileFinder is …

Men's Mental Health: A Call To Social Workers, Kevin Shafer, Douglas Wendt

Faculty Publications

Substantial attention is paid to the mental health needs of women and children by social work researchers, educators, and practitioners—and with good reason, as these are two vulnerable populations in U.S. society. However, the status of men's mental health; its resulting effect on individuals, families, and communities; and the various challenges associated with it are often overlooked by social workers. The authors document the prevalence of common mental health issues among men in the United States, the unique problems that men face, and help-seeking behaviors. They also discuss how social work is in an exceptional position to help men, and …

Use Of Craigslist.Org To Hook Up: Age Differences In Sex Requests, Hiv Disclosure And Negotiated Safety Among Men-Seeking-Men, Kristen Clements-Nolle, Aliya Buttar, Lindsey Dermid-Gray, Tyler Peterson, Andrea Esp

Nevada Journal of Public Health

Data from 984 “men-seeking-men” Craigslist.org postings in five cities were analyzed to assess differences in sexual requests, HIV status disclosure, and negotiated safety between young (18-24 years) and older (25 years and older) men who have sex with men (MSM). Young MSM were less likely than older MSM to post their HIV status or the preferred status of a partner (p=0.04), disclose and/or request a partner who was disease and drug free (p=.01), and request use of a condom in their posting (p=0.01). Interventions aimed at changing the culture and content of postings on Craigslist.org by encouraging HIV status disclosure …

Antidepressant Interactions Of Ketamine And Glycogen Synthase Kinase-3 (Gsk3) In Mice, Kimberlee Downey

Open Access Theses

Depression is a prevalent and debilitating mood disorder afflicting nearly one in five people in the United States. Current medications used for treatment of depression are inadequate because they have a delayed onset of therapeutic benefit, low efficacy, several side effects, and require chronic administration. This presents the need for improved antidepressant therapies. Ketamine, a general anesthetic, was recently shown to have rapid-acting antidepressant effects at a sub-anesthetic dose. It is unknown how ketamine elicits an antidepressant effect, but several mechanisms have been proposed, including glycogen synthase kinase-3 (GSK3) inhibition and a-amino-3-hydroxy-5-methylospxazol-4-propionic acid (AMPA) receptor activation. This thesis focuses on …

The Association Between Perceived Parenting Styles And Aggression In Mexican American Young Adults, Maria R. Medrano

Theses and Dissertations

The relationship between parenting styles and aggression in children has recently received ample attention throughout the psychological literature, with some aspects of this relationship yielding consistent results while others involve more complex dynamics that require further exploration. One factor that may influence both parenting styles and aggression is culture. While many researchers have investigated the relationship between culture and parenting styles, as well as the relationship between culture and aggression, there appears to be a lack of research investigating the relationship and interactions among these three constructs. It is important to further explore the relationship between perceived parenting styles and …

Adaptive, Group Sequential Designs That Balance The Benefits And Risks Of Wider Inclusion Criteria, Michael Rosenblum, Brandon S. Luber, Richard E. Thompson, Daniel F. Hanley

Johns Hopkins University, Dept. of Biostatistics Working Papers

We propose a new class of adaptive randomized trial designs aimed at gaining the advantages of wider generalizability and faster recruitment, while mitigating the risks of including a population for which there is greater a priori uncertainty. Our designs use adaptive enrichment, i.e., they have preplanned decision rules for modifying enrollment criteria based on data accrued at interim analyses. For example, enrollment can be restricted if the participants from predefined subpopulations are not benefiting from the new treatment. To the best of our knowledge, our designs are the first adaptive enrichment designs to have all of the following features: the …

Collagen Gel Formation In The Presence Of A Carbon Nanobrush, George W. Dombi, Kaushalkumar Purohit, Lenore M. Martin, Sze C. Yang

Chemistry Faculty Publications

Type I, bovine skin collagen was allowed to gel in the presence of various concentrations of a carbon nanotube material covered with a polystyrene/polyaniline copolymer, called a carbon nanobrush (CNB). The rate of collagen gelation was enhanced by the presence of the CNB in a dose dependent manner. The extent of collagen gelation was due to the concentration of collagen and not the amount of CNB. Collagen D-periodicity, and average fibril diameter were unchanged by the CNB material as seen in transmission electron micrographs. Gel tensile strength was reduced by the presence of the CNB in a dose related manner. …

Fluorescent Carbon Nanoparticles, Ya-Ping Sun

Clemson Patents

Disclosed are photoluminescent particles. The particles include a core nano-sized particle of carbon and a passivation agent bound to the surface of the nanoparticle. The passivation agent can be, for instance, a polymeric material. The passivation agent can also be derivatized for particular applications. For example, the photoluminescent carbon nanoparticles can be derivatized to recognize and bind to a target material, for instance a biologically active material, a pollutant, or a surface receptor on a tissue or cell surface, such as in a tagging or staining protocol.

The Global Distribution Of Diet Breadth In Insect Herbivores, Robert Marquis, Matthew Forister, Vojtech Novotny, Anna Panorska, Leontine Baje, Yves Basset, Philip Butterill, Lukas Cizek, Phyllis Coley, Francesca Dem, Ivone Diniz, Pavel Drozd, Mark Fox, Andrea Glassmire, Rebecca Hazen, Jan Hrcek, Joshua Jahner, Ondrej Kaman, Tomasz Kozubowski, Thomas Kursar, Owen Lewis, John Lill, Scott Miller, Helena Morais, Masashi Murakami, Herbert Nickel, Nicholas Pardikes, Robert Ricklefs, Michael Singer, Angela Smilanich, John Stireman, Santiago Villamarín-Cortez, Stepan Vodka, Martin Volf, David Wagner, Thomas Walla, George Weiblen, Lee Dyer

Biology Department Faculty Works

Understanding variation in resource specialization is important for progress on issues that include coevolution, community assembly, ecosystem processes, and the latitudinal gradient of species richness. Herbivorous insects are useful models for studying resource specialization, and the interaction between plants and herbivorous insects is one of the most common and consequential ecological associations on the planet. However, uncertainty persists regarding fundamental features of herbivore diet breadth, including its relationship to latitude and plant species richness. Here, we use a global dataset to investigate host range for over 7,500 insect herbivore species covering a wide taxonomic breadth and interacting with more than …

The Quest For Ash Resistance To Eab: Towards A Mechanistic Understanding, Daniel A. Herms, Don Cipollini, K. S. Knight, J. L. Koch, T. M. Poland, Chad Michael Rigsby, Justin G.A. Whitehill, Pierluigi Bonello

Biological Sciences Faculty Publications

Since emerald ash borer (EAB), Agrilus planipennis, was discovered in North America in 2002, it has killed many millions of ash trees in North America, and ash mortality now exceeds 99% near the epicenter of the invasion in southeast Michigan (Klooster et al. 2014). The development of EAB-resistant ash trees will be critical for restoration of ash in natural and urban forests. Goals of our collaboration are to identify, breed and screen ash germplasm for EAB resistance and silvicultural traits; and identify mechanisms of EAB resistance to facilitate breeding and screening.

Treating Proximal Tibial Growth Plate Injuries Using Poly(Lactic-Co-Glycolic Acid) Scaffolds, Amanda Clark, J. Zach Hilt, Todd A. Milbrandt, David A. Puleo

Biomedical Engineering Faculty Publications

Growth plate fractures account for nearly 18.5% of fractures in children. Depending on the type and severity of the injury, inhibited bone growth or angular deformity caused by bone forming in place of the growth plate can occur. The current treatment involves removal of the bony bar and replacing it with a filler substance, such as a free fat graft. Unfortunately, reformation of the bony bar frequently occurs, preventing the native growth plate from regenerating. The goal of this pilot study was to determine whether biodegradable scaffolds can enhance native growth plate regeneration following a simulated injury that resulted in …

Neuroinflammation And J2 Prostaglandins: Linking Impairment Of The Ubiquitin-Proteasome Pathway And Mitochondria To Neurodegeneration, Maria E. Figueiredo-Pereira, Patricia Rockwell, Thomas Schmidt-Glenewinkel, Peter Serrano

Publications and Research

The immune response of the CNS is a defense mechanism activated upon injury to initiate repair mechanisms while chronic over-activation of the CNS immune system (termed neuroinflammation) may exacerbate injury. The latter is implicated in a variety of neurological and neurodegenerative disorders such as Alzheimer and Parkinson diseases, amyotrophic lateral sclerosis, multiple sclerosis, traumatic brain injury, HIV dementia, and prion diseases. Cyclooxygenases (COX-1 and COX-2), which are key enzymes in the conversion of arachidonic acid into bioactive prostanoids, play a central role in the inflammatory cascade. J2 prostaglandins are endogenous toxic products of cyclooxygenases, and because their levels are significantly …

In Vivo Cigarette Smoke Exposure Decreases Ccl20, Slpi, And Bd-1 Secretion By Human Primary Nasal Epithelial Cells, James Jukosky, Benoit J. Gosselin, Leah Foley, Tenzin Dechen, Steven Fiering, Mardi A. Crane-Godreau

Dartmouth Scholarship

Smokers and individuals exposed to second-hand cigarette smoke have a higher risk of developing chronic sinus and bronchial infections. This suggests that cigarette smoke (CS) has adverse effects on immune defenses against pathogens. Epithelial cells are important in airway innate immunity and are the first line of defense against infection. Airway epithelial cells not only form a physical barrier but also respond to the presence of microbes by secreting antimicrobials, cytokines, and chemokines. These molecules can lyse infectious microorganisms and/or provide signals critical to the initiation of adaptive immune responses. We examined the effects of CS on antimicrobial secretions of …

Cohort Of Birth Modifies The Association Between Fto Genotype And Bmi, James Niels Rosenquist, Steven F. Lehrer, A. James O'Malley, Alan M. Zaslavsky, Jordan W. Smoller, Nicholas A. Christakis

Dartmouth Scholarship

A substantial body of research has explored the relative roles of genetic and environmental factors on phenotype expression in humans. Recent research has also sought to identify gene-environment (or g-by-e) interactions, with mixed success. One potential reason for these mixed results may relate to the fact that genetic effects might be modified by changes in the environment over time. For example, the noted rise of obesity in the United States in the latter part of the 20th century might reflect an interaction between genetic variation and changing environmental conditions that together affect the penetrance of genetic influences. To evaluate this …

A New Method For Estimating Species Age Supports The Coexistence Of Malaria Parasites And Their Mammalian Hosts, Joana C. Silva, Amy Egan, Cesar Arze, John L. Spouge, David G. Harris

Harold W. Manter Laboratory of Parasitology: Library Materials

Species in the genus Plasmodium cause malaria in humans and infect a variety of mammals and other vertebrates. Currently, estimated ages for several mammalian Plasmodium parasites differ by as much as one order of magnitude, an inaccuracy that frustrates reliable estimation of evolutionary rates of disease-related traits. We developed a novel statistical approach to dating the relative age of evolutionary lineages, based on Total Least Squares regression. We validated this lineage dating approach by applying it to the genus Drosophila. Using data from the Drosophila 12 Genomes project, our approach accurately reconstructs the age of well-established Drosophila clades, including …

Recent Origin Of Low Trabecular Bone Density In Modern Humans, Habiba Chirchir Phd, Tracy L. Kivell, Christopher B. Ruff, Jean-Jacques Hublin, Kristian J. Carlson, Bernhard Zipfel, Brian G. Richmond

Biological Sciences Faculty Research

Humans are unique, compared with our closest living relatives (chimpanzees) and early fossil hominins, in having an enlarged body size and lower limb joint surfaces in combination with a relatively gracile skeleton (i.e., lower bone mass for our body size). Some analyses have observed that in at least a few anatomical regions modern humans today appear to have relatively low trabecular density, but little is known about how that density varies throughout the human skeleton and across species or how and when the present trabecular patterns emerged over the course of human evolution. Here, we test the hypotheses that (i) …
