We characterized the differentiation of rat bone marrow-derived mesenchymal stem cells (BM-MSCs) into tenocyte-like cells in response to bone morphogenetic protein-12 (BMP-12). BM-MSCs were prepared from Sprague-Dawley rats and cultured as monolayers. Recombinant BMP-12 treatment (10 ng/ml) of BM-MSCs for 12 hours in vitro markedly increased expression of the tenocyte lineage markers scleraxis (Scx) and tenomodulin (Tnmd) over 14 days. Treatment with BMP-12 for a further 12-hour period had no additional effect. Colony formation assays revealed that ∼80% of treated cells and their progeny were Scx- and Tnmd-positive. BM-MSCs seeded in collagen scaffolds and similarly treated with a single dose …

A Role For Amyloid In Cell Aggregation And Biofilm Formation, Melissa C. Garcia, Janis T. Lee, Caleen B. Ramsook, David Alsteens, Yves F. Dufrêne, Peter N. Lipke

Publications and Research

Cell adhesion molecules in Saccharomyces cerevisiae and Candida albicans contain amyloid-forming sequences that are highly conserved. We have now used site-specific mutagenesis and specific peptide perturbants to explore amyloid-dependent activity in the Candida albicans adhesin Als5p. A V326N substitution in the amyloid-forming region conserved secondary structure and ligand binding, but abrogated formation of amyloid fibrils in soluble Als5p and reduced cell surface thioflavin T fluorescence. When displayed on the cell surface, Als5p with this substitution prevented formation of adhesion nanodomains and formation of large cellular aggregates and model biofilms. In addition, amyloid nanodomains were regulated by exogenous peptides. An amyloid-forming …

The Online "Supplemental" Workshop: Course Enrichment To Support Novice Teachers' Analysis Of Classroom Video, Laura H. Baecher, Shiao-Chuan Kung

Publications and Research

As online learning and video technology become more consistent components of teacher education, the opportunities to blend the affordances of both was piloted in a specially designed online workshop. This workshop was designed to help teacher candidates become more sophisticated in their ability to recognize and describe specific teaching behaviors in videoed lessons. Using QuickTime Pro, iMovie, and Blackboard, a self-paced, asynchronous workshop to introduce techniques for observing and analyzing teachers and classes on video was created. Through a series of video tutorials and activities, teacher candidates were guided through the process of viewing the same video clip through different …

Micropropagation And Medium-Term Conservation Of Rosa Pulverulenta, Somayeh Kavand, Maryam Jafarkhani Kermani, Ali Haghnazari, Pegah Khosravi, Mohamad Reza Azimi

Publications and Research

In Iran, a large number of Rosa species have been exposed to extinction and therefore preservation techniques are necessary to safeguard their future. In the present investigation, the objectives were to optimize the micropropagation and medium-term conservation of one of these wild species, Rosa pulverulenta. At proliferation stage, the maximum number of new leaves (9.6) were produced on the medium containing 4 µM BAP + 0 µM GA₃, whereas the maximum number of axillary shoots (4.1) were observed in the medium containing 4 µM BAP + 3 µM GA₃. The results for rooting experiments suggested …

Information Is Social: Information Literacy In Context, Jen Hoyer

Publications and Research

This paper aims to discuss traditional conceptions of information literacy as created within an academic context to address information needs within this context. It seeks to present alternative realities of information use outside the academic sector, and to suggest that information literacy instruction within academia does not go far enough in preparing students for the information society beyond university. The aim is then to follow this by discussion of appropriate information literacy models to prepare young people for information use in a variety of workplace environments.

Publications and Research

Cationic lipids have long been known to serve as antibacterial and antifungal agents. Prior efforts with attachment of cationic lipids to carbohydrate-based surfaces have suggested the possibility that carbohydrate-attached cationic lipids might serve as antibacterial and antifungal pharmaceutical agents. Toward the understanding of this possibility, we have synthesized several series of cationic lipids attached to a variety of glycosides with the intent of generating antimicrobial agents that would meet the requirement for serving as a pharmaceutical agent, specifically that the agent be effective at a very low concentration as well as being biodegradable within the organism being treated. The initial …

Cognitive Control In Majority Search: A Computational Modeling Approach, Hongbin Wang, Xun Liu, Jin Fan

Publications and Research

Despite the importance of cognitive control in many cognitive tasks involving uncertainty, the computational mechanisms of cognitive control in response to uncertainty remain unclear. In this study, we develop biologically realistic neural network models to investigate the instantiation of cognitive control in a majority function task, where one determines the category to which the majority of items in a group belong. Two models are constructed, both of which include the same set of modules representing task-relevant brain functions and share the same model structure. However, with a critical change of a model parameter setting, the two models implement two different …

Opportunity/Threat Spirals In The U.S. Women's Suffrage And German Anti-Immigration Movements, Roger Karapin

Publications and Research

Many have noted that protesters sometimes expand political opportunities for later protests, but there has been little analysis of how this occurs. The problem can be addressed by analyzing opportunity/threat spirals, which involve positive feedback among: actions by challengers (bold protests and the formation of alliances between challenger groups); opportunity-increasing actions by authorities and elites (elite divisions and support, procedural reforms, substantive concessions, and police inaction); and threat-increasing actions by authorities and elites (new grievance production and excessive repression). Interactions among these eight mechanisms are demonstrated in two cases of social movement growth, the U.S. women's suffrage movement of the …

Heparan Sulfate Proteoglycans Mediate Interstitial Flow Mechanotransduction Regulating Mmp-13 Expression And Cell Motility Via Fak-Erk In 3d Collagen, Zhong-Dong Shi, Hui Wang, John M. Tarbell

Publications and Research

Background Interstitial flow directly affects cells that reside in tissues and regulates tissue physiology and pathology by modulating important cellular processes including proliferation, differentiation, and migration. However, the structures that cells utilize to sense interstitial flow in a 3-dimensional (3D) environment have not yet been elucidated. Previously, we have shown that interstitial flow upregulates matrix metalloproteinase (MMP) expression in rat vascular smooth muscle cells (SMCs) and fibroblasts/myofibroblasts via activation of an ERK1/2-c-Jun pathway, which in turn promotes cell migration in collagen. Herein, we focused on uncovering the flow-induced mechanotransduction mechanism in 3D. Methodology/Principal Findings Cleavage of rat vascular SMC surface …

Antibodies Elicited In Response To Ebna-1 May Cross- React With Dsdna, Pragya Yadav, Hoa Tran, Roland Ebegbe, Paul Gottlieb, Hui Wei, Rita H. Lewis, Alice Mumbey-Wafula, Atira Kaplan, Elina Kholdarova, Linda Spatz

Publications and Research

Background:Several genetic and environmental factors have been linked to Systemic Lupus Erythematosus (SLE). One environmental trigger that has a strong association with SLE is the Epstein Barr Virus (EBV). Our laboratory previously demonstrated that BALB/c mice expressing the complete EBNA-1 protein can develop antibodies to double stranded DNA (dsDNA). The present study was undertaken to understand why anti-dsDNA antibodies arise during the immune response to EBNA-1.

Methodology/Principal Findings: In this study, we demonstrated that mouse antibodies elicited in response to EBNA-1 cross-react with dsDNA. First, we showed that adsorption of sera reactive with EBNA-1 and dsDNA, on dsDNA cellulose …
