Light-Induced Expression Of A Blue Coral Protein In An Industrial Fungus, 2018 Union College
Light-Induced Expression Of A Blue Coral Protein In An Industrial Fungus, Lindsay Tomczak
The ultimate goal of this research project is to improve the growth and structural characteristics of an Ecovative Design LLC (Green Island, NY) production strain to produce commercial biomaterials for packaging. These biomaterials are produced from renewable resources and can be easily broken down after they fulfill their purpose, unlike the commonly used materials today (such as Styrofoam). In an effort to quantify the light-reactivity of the fungus, a codon-optimized DNA sequence coding a blue chromoprotein was introduced and utilized as a visual reporter gene. Transcriptional controlling sequences were identified from orthologs to specific light-regulated genes and were combined with ...
Biological Soil Crusts In A Northeastern Pine Barren: Composition And Ecological Effects, 2018 Union College - Schenectady, NY
Biological Soil Crusts In A Northeastern Pine Barren: Composition And Ecological Effects, Jessica Gilbert
Biological soil crusts (BSCs), otherwise known as cryptogamic soil crusts, biocrusts, or cyanobacterial crusts, are soil aggregations hosting diverse biotic communities. They are composed of cyanobacteria and algae, and generally have a covering of moss and/or lichen. BSCs are typically found in arid to semi-arid regions throughout the world, and are integral soil stabilizers, moisture retainers, and nitrogen fixers in these communities. Along with these factors, BSCs are able to impact germination and establishment of plants, either as an accompanying influence, or direct result of those listed above. BSCs have yet to be formally described in the inland northeastern ...

Effects Of Magnesium Deprivation On The Flora Of The Gastrointestinal Tract, 2018 The College at Brockport
Effects Of Magnesium Deprivation On The Flora Of The Gastrointestinal Tract, Tricia Cooke
Senior Honors Theses
Crohn’s disease, a pathological condition characterized by gastrointestinal (GI) inflammation and mucosal changes is often associated with hypomagnesemia resulting from changes in the GI mucosa and an increased GI transit rate. Furthermore, certain types of bacteria are also implicated in the formation of GI neoplasia and carcinogenesis. A variety of physiologic changes such as an increase in the systemic stress response, severity of the inflammatory response, or an exaggerated immune response is known to occur in Magnesium (Mg2+) deficient mice and rats. To understand to what extent Mg2+ deficiency could contribute to the aggravation of such diseases by ...
Modeling And Analyzing An Optogenetic System For Photoactivatable Protein Dissociation, 2018 University of Connecticut
Modeling And Analyzing An Optogenetic System For Photoactivatable Protein Dissociation, Anvin Thomas, James Schaff
Honors Scholar Theses
Computational modeling of cell-cell interactions can grant clues and can answer questions about an experiment, especially for observations about binding interactions and kinetics. This approach was used to investigate an interaction between a light-oxygen-voltage (LOV) domain and an engineered protein called Zdark (Zdk). The LOV domain is membrane-bound while Zdk is cytosolic. The LOV domain and Zdk bind strongly in dark (Kd 26.2 nM), and weakly upon exposure to blue light (Kd > 4 μM). Total internal reflection fluorescence (TIRF) images are acquired of Zdk, the fluorescent species bound to a mCherry tag, and the loss of fluorescence ...
Literature Review And Proposal: Yoga As Group Exercise Involving Oxytocin Release For Positive Mood Improvement, 2018 Bowling Green State University
Literature Review And Proposal: Yoga As Group Exercise Involving Oxytocin Release For Positive Mood Improvement, Rachel Fenton
A literature review discusses yoga and health involving oxytocin creates the premise for a proposal combining the knowledge of yoga and its health benefits along with oxytocin's potential involvement during group exercise, yoga specifically. The proposed study's results of oxytocin measures and questionnaires have the potential to develop an understanding of the possible impacts of yoga on mood, particularly relationships between group exercise and yoga, which may help develop forms of group exercise or implement group yoga to assist or replace treatment for stress-caused or stress-related disorders.
Different Methodologies To Characterize And Diagnose Sickle Cell Disease In Both Developed And Developing Nations, 2018 Dominican University of California
Different Methodologies To Characterize And Diagnose Sickle Cell Disease In Both Developed And Developing Nations, Mohammed Alharbi
Master's Theses and Capstone Projects
Sickle cell disease (SCD) is a genetic blood disorder that causes the RBC to become sickle shaped due to a mutation in the β-globin gene encoding the protein hemoglobin. This disease causes reduced oxygen carrying capacity of RBC resulting in painful crisis, hemolytic anemia, and infection susceptibility. SCD affects around 100,000 individuals in USA alone and 14 million people globally. SCD affected individuals have high mortality rates. Early detection and constant monitoring of this disease is essential. The following review focuses on various methodologies that have emerged in the diagnosis of SCD. Also, low cost methods that can be ...
Effect Of An Arginine-To-Isoleucine Active Site Mutation On Escherichia Coli Malate Dehydrogenase Enzymatic Activity, 2018 Olivet Nazarene University
Effect Of An Arginine-To-Isoleucine Active Site Mutation On Escherichia Coli Malate Dehydrogenase Enzymatic Activity, Jon Zatorski, Bruce J. Heyen
Scholar Week 2016 - present
Citric acid cycle enzymes function in an environment with numerous substrate analogues and therefore contain active site residue organizations that confer high substrate specificity. Extensive research into the catalytic mechanism of Escherichia coli malate dehydrogenase (eMDH) has identified arginine81 as being crucial to catalysis. In this investigation, an engineered eMDH having an Ile81 rather than an Arg81 (R81I) was isolated using a hexahistadine (His6) tag. Enzymatic activity of the R81I mutant with respect to malate, lactate, and pyruvate was explored. The R81I mutant did show significant activity toward malate, but did not show significant activity toward lactate or pyruvate. Investigations ...

Assay Of The Reverse Osmosis Purified Water In The Life Science Building At Bowling Green State University, Ohio, Nicholas Mendenhall, Scott O. Rogers, Neocles B. Leontis
Contaminated water sources can cause problems for scientific research and result in costly delays and failures of experiments. At Bowling Green State University, the reverse osmosis supply circulating in the Life Sciences Building has been measurably contaminated for nearly three years, corresponding to a change in servicing of the system. While servicing has been accelerated, the contamination in the system remains. The focus of this research was to identify the species of bacteria and fungi growing inside of the water system so that it might alert those servicing the system, and to begin to eliminate the contamination. Reverse osmosis water ...
Biochemical Analysis Of Dimethyl Suberimidate-Crosslinked Yeast Nucleosomes, 2018 University of Massachusetts Medical School
Biochemical Analysis Of Dimethyl Suberimidate-Crosslinked Yeast Nucleosomes, Yuichi Ichikawa, Paul D. Kaufman
Open Access Articles
Nucleosomes are the fundamental unit of eukaryotic chromosome packaging, comprised of 147 bp of DNA wrapped around two molecules of each of the core histone proteins H2A, H2B, H3, and H4. Nucleosomes are symmetrical, with one axis of symmetry centered on the homodimeric interaction between the C-termini of the H3 molecules. To explore the functional consequences of nucleosome symmetry, we designed an obligate pair of H3 heterodimers, termed H3X and H3Y, allowing us to compare cells with single or double H3 alterations. Our biochemical validation of the heterodimeric X-Y interaction included intra-nucleosomal H3 crosslinking using dimethyl suberimidate (DMS). Here, we ...
History Of The 3rs In Toxicity Testing: From Russell And Burch To 21st Century Toxicology, 2018 Johns Hopkins University
History Of The 3rs In Toxicity Testing: From Russell And Burch To 21st Century Toxicology, Martin L. Stephens, Nina S. Mak
Martin Stephens, Ph.D.
Toxicity testing is a key part of the process of assessing the hazards, safety, or risk that chemicals and other substances pose to humans, animals, or the environment. Standardized methods for such testing, typically involving animals, began to emerge during the first half of the 20th century. In 1959, British scientists William Russell and Rex Burch proposed a framework for reducing, refining, or replacing animal use in toxicology and other forms of biomedical experimentation. This “3Rs” or “alternatives” approach emerged at a time of growing sensitivity to the use of animals in experimentation, and progress in its implementation has been ...
Studies Of Amino Acid Mutations In Drug Resistance Of The Smo Protein, 2018 University of Nebraska at Omaha
Studies Of Amino Acid Mutations In Drug Resistance Of The Smo Protein, Eunice Wintona
Student Research and Creative Activity Fair
Smoothened receptor (SMO) is a protein that in humans, is encoded by the SMO gene. A systemic mutation in its binding pocket helps predict the sensitivity of mutant proteins to different drugs. Known as a GPCR-like receptor, it is a component of the hedgehog signaling pathway; a pathway involved in body patterning and the regulation of adult stem cells. An uncontrolled or inappropriate activation of the Hedgehog pathway drives tumor progression in cancers and a number of birth defects. To achieve these goals, the molecular modeling software MOE was used to build small molecules and drug molecules like Vismodegib and ...

A Standard Nomenclature For Referencing And Authentication Of Pluripotent Stem Cells, 2018 Charité - Universitätsmedizin Berlin
A Standard Nomenclature For Referencing And Authentication Of Pluripotent Stem Cells, Andreas Kurtz, Stefanie Seltmann, Kelly P. Smith
Open Access Articles
Unambiguous cell line authentication is essential to avoid loss of association between data and cells. The risk for loss of references increases with the rapidity that new human pluripotent stem cell (hPSC) lines are generated, exchanged, and implemented. Ideally, a single name should be used as a generally applied reference for each cell line to access and unify cell-related information across publications, cell banks, cell registries, and databases and to ensure scientific reproducibility. We discuss the needs and requirements for such a unique identifier and implement a standard nomenclature for hPSCs, which can be automatically generated and registered by the ...

The Wisconsin State Laboratory of Hygiene challenged Wisconsin laboratories to examine their biosafety practices and improve their culture of biosafety. One hundred three clinical and public health laboratories completed a questionnaire-based, microbiology-focused biosafety risk assessment. Greater than 96% of the respondents performed activities related to specimen processing, direct microscopic examination, and rapid nonmolecular testing, while approximately 60% performed culture interpretation. Although they are important to the assessment of risk, data specific to patient occupation, symptoms, and travel history were often unavailable to the laboratory and, therefore, less contributory to a microbiology-focused biosafety risk assessment than information on the specimen source ...
