An Activity Aimed At Improving Student Explanations Of Biological Mechanisms, Caleb M. Trujillo, Trevor R. Anderson, Nancy J. Pelaez
An Activity Aimed At Improving Student Explanations Of Biological Mechanisms, Caleb M. Trujillo, Trevor R. Anderson, Nancy J. Pelaez
PIBERG Instructional Innovation Materials
This document is intended for use by instructors and their students. The activity contains steps to introduce students to the MACH model involving analyzing and discussing explanations about biological mechanisms. Initially, students read modified articles about biological mechanisms during class, although instructors may prefer to assign readings outside of class before the activity. During the activity, students are required to analyze the readings for evidence of research methods, analogies, context, and mechanisms. In so doing, students learn how to integrate the information pertaining to each of the MACH model components into a coherent explanation about their biological mechanism. After performing …
A Tetrahedral Version Of The Mach Model For Explaining Biological Mechanisms, Caleb M. Trujillo, Trevor R. Anderson, Nancy J. Pelaez
A Tetrahedral Version Of The Mach Model For Explaining Biological Mechanisms, Caleb M. Trujillo, Trevor R. Anderson, Nancy J. Pelaez
PIBERG Instructional Innovation Materials
This document is intended for both instructors and students. Modified from the original MACH model this version, once cut and folded, creates a tetrahedral model that can conveniently be used as a teaching and learning tool to inform and guide students on how to write expert quality explanations of biological mechanisms. Each vertex of the tetrahedron represents a component of the model namely, Methods, Analogy, Context, and How. For a coherent and complete explanation about molecular mechanisms, it is important to integrate information pertaining to all four components of the model. The tetrahedral MACH model has been tested in both …

Naphthenic acids (NAs) are water-soluble components of petroleum. The characterization and quantification of NAs by analytical methods have proved quite challenging, whilst the toxic effects of these water-soluble compounds on a variety of organisms adversely affecting reproduction and steroid production is becoming apparent. In this study, we report a fluorescence-based competitive binding method for rapid sensing of the presence of NAs using cellulosic peptide array strips as sensors. The peptide array was designed from sequences derived from the estrogen receptor (ER). Several of these peptides were able to detect the presence of NAs at low micromolar (∼5 mg L−1 …
Neural Stem Cells As A Model To Study Huntington’S Disease, Rawan Bakhsh
Neural Stem Cells As A Model To Study Huntington’S Disease, Rawan Bakhsh
Dissertations, Masters Theses, Capstones, and Culminating Projects
Huntington’s disease (HD) is a heritable neurodegenerative disorder that affects muscle coordination and diminishes cognitive abilities, by affecting the medium spiny neurons in the brain. In HD patients, neurons are damaged and destroyed because of the toxicity of the mutant Huntington protein (mHtt). The mechanism of how mHtt protein affects the neurons is unknown. In this study we explored the effects of mHtt expression by looking at changes in huntingtin localization, changes in the expression and co-localization of related proteins and differences in cell morphology. We examine how this expression affects the cytoskeletal structures using neural stem cells Q7 (wild …
Phthalates And Phthalate Alternatives: Effects On Proliferative And Estrogenic Target Genes In Ishikawa Cells, Ranjani Sundar '15, Ping Yin, Serdar E. Bulun
Phthalates And Phthalate Alternatives: Effects On Proliferative And Estrogenic Target Genes In Ishikawa Cells, Ranjani Sundar '15, Ping Yin, Serdar E. Bulun

Phthalates are used as plasticizers in many of the products found in medical, household, and industrial applications. Much research has not been completed on the effects of these phthalates as potential endocrine disrupting chemicals (EDCs). As these chemicals are ingested, the mechanism by which they affect the reproductive system is largely unknown. The purpose of this study was to observe how 2 phthalates, Di-n-butyl phthalate (DBP) and Diisononyl phthalate (DINP), and 2 phthalate alternatives, Dioctyl terephthalate (DOTP) and BHT (butylated hydroxytoluene)affect uterine cells in comparison to a vehicle treatment and 17β-Estradiol treatment. Changes in expression of mRNA were observed using …
