What Is The Optimal Timing Of Embryo Biopsy For Diagnosing Genetic Abnormalities?, Nekhama Riznyk
What Is The Optimal Timing Of Embryo Biopsy For Diagnosing Genetic Abnormalities?, Nekhama Riznyk
The Science Journal of the Lander College of Arts and Sciences
Introduction and Purpose: This paper examines current trends in assisted reproductive technology, specifically the use of preimplantation genetic diagnosis (PGD to help in the preimplantation detection of genetic abnormalities such as monogenetic diseases and aneuploidy. PGD can be carried out in different stages, and the timing of the procedure has become one of the major issues in implementation. Three major stages of biopsy have been applied when carrying out PGD: Polar body biopsy (pre-conception), cleavage stage biopsy (3 days after conception), and blastocyst stage biopsy (6 days after conception). The purpose of the paper was to explore these stages and …
Improving The Prediction And Management Of Intrauterine Growth Restriction, Shulamis Sadowsky
Improving The Prediction And Management Of Intrauterine Growth Restriction, Shulamis Sadowsky
The Science Journal of the Lander College of Arts and Sciences
Intrauterine growth restriction (IUGR) is a potentially fatal and often missed obstetric complication. The fetus is deprived of vital blood, oxygen, and nutrients due to faulty maternofetal circulation, leading to a severe lack of fetal growth. Since current prenatal testing is highly ineffective at diagnosing the condition, many babies with IUGR are negatively impacted before, during, and after birth. This paper assesses alternative and innovative detection and management methods of IUGR. Current routine prenatal care includes simple fundal height measurements to screen for IUGR. This analysis finds that other testing may increase the rate of detection of the disease. Maternal …

Can Physicians Transfer Bacteria Onto Patients Through Their Neckties?, Alexandra Pinkhas
Can Physicians Transfer Bacteria Onto Patients Through Their Neckties?, Alexandra Pinkhas
The Science Journal of the Lander College of Arts and Sciences
Hospital-acquired infections are exacerbated by the presence of transmission agents such as bacteria on neckties. Physicians can put patients at risk of infections if bacteria contaminate their ties during their normal hospital routines. In the hospital setting, some of the most common bacteria include Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa, Staphylococcus epidermidis, Enterococcus, Streptococcus pneumoniae, Methicillin-resistant Staphylococcus aureus (MRSA) and Clostridioides difficile. Studies have shown that neckties can act as transmission agents, especially when they come into contact with patients. Additionally, the type of material used to make a necktie determines the viability of bacteria. Wearing neckties increases risk for …
Intraoral Appliance Therapy - A Better Alternative For Apnea Than Cpap?, Bryan Teigman
Intraoral Appliance Therapy - A Better Alternative For Apnea Than Cpap?, Bryan Teigman
The Science Journal of the Lander College of Arts and Sciences
Obstructive sleep apnea (OSA) is a condition where there is a physiologic hindrance of airflow to the lungs, triggering the brain to interfere with the sleep cycle and awaken an individual to provide sufficient oxygen flow. For years, the continuous positive airway pressure (CPAP) machine has been the gold standard of care for patients suffering from OSA. Nonetheless, the machine has its flaws of being bulky, noisy, and other side effects, causing a low adherence rate and thus a lower relief rate of OSA symptoms. Accordingly, there have been many researchers seeking a more effective way to treat OSA, such …
Microplastics In Wetlands Of West Central Ohio : Concentration And Distribution, Mitchell Link
Microplastics In Wetlands Of West Central Ohio : Concentration And Distribution, Mitchell Link
Browse all Theses and Dissertations
Wetlands provide many valuable ecosystem services; however, an emerging global contaminant—microplastic (< 5 mm)—may be degrading this important resource. Few studies have extensively surveyed microplastic distribution in wetlands over a broad spatial area. Therefore, the goal of this study is to identify where microplastics are accumulating in wetlands, and whether there is any correlation between microplastic concentration and wetland quality. Soil samples were collected from 30 wetlands in west–central Ohio. Samples were physically separated, density separated, and digested. Average microplastic concentrations were 637 ± 494 items per kg soil per wetland. Higher quality wetlands are accumulating larger concentrations of microplastics. This relationship seems to be driven by greater accumulation of microplastics in forested wetlands than in wetlands surrounded by agriculture. There is no clear distribution pattern of microplastics within wetlands. These results provide insight into the role that wetlands have in association with microplastic accumulation.
Is Intermittent Fasting A Better Option Than Continuous Calorie Restriction?, Joseph J Cynamon
Is Intermittent Fasting A Better Option Than Continuous Calorie Restriction?, Joseph J Cynamon
The Science Journal of the Lander College of Arts and Sciences
Intermittent fasting has become an increasingly popular diet for weight loss in the United States in the past ten years. Proponents of intermittent fasting claim that restricting calories via a fasting period yields more significant weight loss and better improvements in biomarkers for longevity than restricting calories continuously. The goal of this paper is to determine whether intermittent fasting leads to weight loss and is more beneficial than continuous calorie restriction. The paper first details the physiological processes which can occur during fasting that are theorized to render fasting advantageous. It then reviews the limited available research that experimentally compares …

Winter canola (Brassica napus L.) is planted in late September through October in central Oklahoma and harvested in June. Three aphid species typically infest canola fields in central Oklahoma: cabbage aphid, Brevicoryne brassicae L.; green peach aphid, Myzus persicae (Sulzer); and turnip aphid, Lipaphis pseudobrassicae (Davis). Predatory insects and spiders and hymenopteran parasitoids that prey on aphids are present in canola fields in central Oklahoma. We used a D-vac suction device to sample aphids and natural enemies in a total of 23 canola fields in central Oklahoma in early November and mid-March of three growing seasons. During the three …

Data To Accompany: How Does Rapid Body Color Change Affect The Conspicuity Of Lizards To Their Predators And Conspecifics?, Lindsey Swierk, Andrés Rojo
Biological Sciences Faculty Scholarship
Predator-prey interactions drive the evolution of prey visual camouflage, but prey species also often require salience to their conspecifics for social signaling purposes. Whether rapid body color change can help to dynamically balance conspecific visibility and predator concealment, in the eyes of each group’s respective visual systems, remains poorly understood. We tested this question using water anoles (Anolis aquaticus), a small lizard that uses rapid dark-to-light body color change to visually camouflage itself from its avian predators across diverse microhabitats. We used digital image analysis and visual modeling to assess the effectiveness of color-matching camouflage in A. aquaticus …

Data To Accompany "Altered Heat-Avoidance Behavior Following Damage To The Extended Architecture Of Mexican Jumping Bean Moth Larvae (Cydia Saltitans)", Anna Purtell, Lindsey Swierk
Biological Sciences Faculty Scholarship
In response to physical damage, organisms must balance physical recovery with adaptive responses to other environmental stressors. Understanding how damage and repair influence adaptive responses to high environmental temperatures is of particular interest in light of global climate change. We investigate the impact of damage and subsequent repair on heat-avoidance behaviors in Cydia saltitans larvae inhabiting host seeds (Sebastiana pavoniana) as protective structures (together colloquially known as “Mexican jumping beans”). These larvae perform temperature-dependent “jumping” or “rolling” behaviors to escape extreme heat, which are crucial for larval survival in their native arid and hot subtropical dry forests. Due …

How Can We Eliminate Peanut Allergies?, Ari Weingarten
How Can We Eliminate Peanut Allergies?, Ari Weingarten
The Science Journal of the Lander College of Arts and Sciences
For a long time, people with peanut allergies have had to carefully read labels, carry around emergency epinephrine injections, and live in fear of accidentally consuming an otherwise benign food that could potentially kill them. Thankfully, researchers have been working on ways to alleviate the harmful effects of these allergies and perhaps even find a cure. In the Learning Early About Peanut allergy (LEAP) study performed in 2015, researchers examined whether the early introduction of peanut consumption could be used to prevent peanut allergies. According to the study, peanuts can be introduced orally to high-risk infants who are sensitized, as …

This paper explores the singing voice in terms of the vocal mechanism’s key anatomical features and the physiology of the vocal function. It focuses on phonation and resonation and examines the anatomy and physiology of the vocal tract and the respiratory system. The aim is to determine whether the singer’s voice is only the product of genetics or due to environmental influences. It conducts a procedure to evaluate how singers use their voices to modify breathing, pitch, volume, and timbre through resonance shaping. It also investigates the hereditary transmission of a good singing voice, on chromosome 12q, between relatives, and …
Investigating Plant Physiological Responses To Global Phylogenetic Diversity Of Glomeromycotina, David Z. Mowbray
Investigating Plant Physiological Responses To Global Phylogenetic Diversity Of Glomeromycotina, David Z. Mowbray
Honors Undergraduate Theses
Arbuscular mycorrhizal (AM) fungi are ubiquitous symbionts of terrestrial plant species with associations predominantly characterized as mutualistic. In addition to well-documented enhancement of host growth response, more recent analyses have demonstrated the conferral of host benefits under numerous biotic and abiotic stressors. However, much of the established evidence originates from studies involving limited AM fungal diversity. Accordingly, this study sought to evaluate the potential effects of inoculation on plant host physiological traits within a growth chamber environment, investigate potential correlations between host trait responses, & assess the degree of phylogenetic signal observed in trait responses due to the presence of …

Active learning tools, such as gamification, have facilitated teamwork and improved decision-making skills in Anatomy and Physiology classes. However, most Anatomy and Physiology labs currently contain dissection activities where students are not likely to engage in inquiry, critical thinking, or problem-solving. Usually, the instructor gives a brief lecture on the topic, and students are left to dissect without understanding how the lecture relates to what is in front of them, which is frustrating. Coupled with the frustration, some students have adverse opinions on dissecting specimens, including hesitation to dissect the specimen and religious or ethical concerns with dissection. Utilizing similar …

Salicylic acid (SA) is a central plant hormone mediating immunity, growth, and development. Recently, studies have highlighted the sensitivity of the SA pathway to changing climatic factors and the plant microbiome. Here we summarize organizing principles and themes in the regulation of SA biosynthesis, signaling, and metabolism by changing abiotic/biotic environments, focusing on molecular nodes governing SA pathway vulnerability or resilience. We especially highlight advances in the thermosensitive mechanisms underpinning SA-mediated immunity, including differential regulation of key transcription factors (e.g., CAMTAs, CBP60g, SARD1, bHLH059), selective protein–protein interactions of the SA receptor NPR1, and dynamic phase separation of the recently identified …

Determination Of Taxonomic Placement Of Falsely-Branched Taxa In Soils Of San Nicolas Island And Reassessment Of The Tolypothrichaceae., Natalie Soliman
Senior Honors Projects
This study was conducted to determine the taxonomic placement of falsely-branched taxa in the soil crusts of San Nicolas Island, which is the largest of the Channel Islands lying off the coast of California. After microscopic analysis of the strains collected from the island, a phylogenetic analysis of 16S rRNA genes, and an analysis of the 16S-23S ITS region, we have identified that these strains belong to the soil genus Spirirestis, which is in the Tolypothrichaceae family. The Tolypothrichaceae is a wellcharacterized monophyletic lineage of non-attenuated, false-branching heteropolar types containing the genera Spirirestis, Hassallia, Tolypothrix, Coleodesmium, and Rexia. The strains …
