In this randomized, independent groups study, 7 male, division III cross-country athletes were supplemented with either carbonyl iron or ferrous sulfate for 6 weeks. Blood hemoglobin, hematocrit, subjective GI distress, subjective fatigue, and relative exertion of recent training were assessed at baseline, 3 and 6 weeks. Results will be analyzed via a detailed analysis of variance to determine significant differences in outcome measures. Statistical ...


The Plant And The Pathogen: Elucidating The Relationship Between Root-Knot Nematodes, Ph Levels, And Arabidopsis Thaliana Development, Rachel Garnett Apr 2022

The Plant And The Pathogen: Elucidating The Relationship Between Root-Knot Nematodes, Ph Levels, And Arabidopsis Thaliana Development, Rachel Garnett

Student Scholar Showcase

Root-knot nematodes (RKNs) within the Meloidogyne genus are considered one of the largest threats to plant health and subsequent crop yield and profit (Forghani and Hajihassani 2020; Bernard et al. 2017). As a pest that presents global consequences, its mitigation through sustainable interventions may confer results for the treatment of similar plant pathogens. A member of the Brassicaeae family, Arabidopsis thaliana, was chosen for this study to determine plant responses to RKN-standard pH media. pH was varied between control and experimental groups, and phenotypic variables of primary root length and plant height were observed and analyzed. Wild-type Arabidopsis thaliana plants ...


Investigating Alternative Induction Of The S. Aureus 80a Prophage, Jody Caretti Apr 2022

Investigating Alternative Induction Of The S. Aureus 80a Prophage, Jody Caretti

Student Scholar Showcase

Widespread antibiotic resistance has quickly become one of the most concerning crises affecting modern medicine, especially in cases of Staphylococcal infections, which have become resistant to all ��-lactam antibiotics. As a result, research into alternative forms of treatment for bacterial infections is a top priority. Bacteriophage therapy is a popular candidate for replacing antibiotics, due to the way the viruses interact with the bacteria. The 80�� prophage integrates its DNA into Staphylococcus aureus strain 10616 via the lysogenic cycle, and replicates with the bacterial cell. When stressed, the bacteria stop replicating and the prophage stimulates the lytic cycle, activating transcription ...

Human Adaptation And Morphological Variation: Expanding Diversity In Anatomy Curriculum, Jordan Cass, Cooker Storm

Seaver College Research And Scholarly Achievement Symposium

Introduction: The recent upturn in our nation’s socio-political conversation has fueled interest in ensuring that college curricula is diverse and inclusive. Because human anatomy is ubiquitous across colleges, it may be a valuable avenue to purposefully incorporate topics of diversity in a way that positively impacts our socio-cultural relationships. Providing students with a scientific understanding of our visible differences may mitigate subconscious bias when we see others who have different features. Purpose: We investigated the biogeographical factors that contribute to the morphological variability of the face, hair, and body size; with the secondary aim of developing diverse and inclusive ...


Endogenous Cftr Expression In Human Epithelial Cell Lines, Zithlaly Amezquita Mar 2022

Endogenous Cftr Expression In Human Epithelial Cell Lines, Zithlaly Amezquita

Undergraduate Research Conference

CFTR (Cystic Fibrosis Transmembrane-conductance Regulator) is a plasma membrane protein that functions as a chloride ion channel on many epithelial cells. There are over 1000 mutations that affect the function of this protein; however, the most common mutation is DF508. CFTR mutations target many secretory organs like pancreas and lungs causing the genetic disease cystic fibrosis (CF), common among Caucasians of northern European origin. Detection of endogenous CFTR expression is possible by a difficult and costly immunoprecipitation method but not by the most used western blotting method. Therefore, the goal of this project was to detect the endogenous CFTR expression ...
