Reliability And Validity Of A Modified Anaerobic Speed Test To Determine Anaerobic Capacity In Ncaa Division Ii Soccer Players, Kenji Murao

Projects

Anaerobic capacity is an important performance variable for soccer athletes to compete at higher levels of competition. The purpose of this study was to develop a sports-specific anaerobic capacity test for soccer players that could be administered on commercial treadmills found in most exercise facilities. The Wingate Anaerobic test (WAnT) is the most common test for anaerobic capacity, however it is a cycle ergometer test, which is not sports-specific to running type athletes. The Anaerobic Speed Test (AST) is an anaerobic capacity test on a treadmill, however the testing protocol (20% incline) cannot be done on commercial treadmills because they …

Alignment Of Mitotic Chromosomes In Human Cells Involves Sr-Like Splicing Factors Btf And Trap150, Sapna Varia, Divya Cheedu, Michael P. Markey, Keshia Torres-Shafer, Vishnu P. Battini, Athanasios Bubulya, Paula A. Bubulya

Biochemistry and Molecular Biology Faculty Publications

Serine-arginine-rich (SR) or SR-like splicing factors interact with exon junction complex proteins during pre-mRNA processing to promote mRNA packaging into mature messenger ribonucleoproteins (mRNPs) and to dictate mRNA stability, nuclear export, and translation. The SR protein family is complex, and while many classical SR proteins have well-defined mRNA processing functions, those of other SR-like proteins is unclear. Here, we show that depletion of the homologous non-classical serine-arginine-rich (SR) splicing factors Bcl2-associated transcription factor (Btf or BCLAF) and thyroid hormone receptor-associated protein of 150 kDa (TRAP150) causes mitotic defects. We hypothesized that the depletion of these SR-like factors affects mitosis indirectly …

A Gram-stain-negative, motile, rod-shaped bacterium designated OCN003T was cultivated from mucus taken from a diseased colony of the coral Montipora capitata in Kāne‘ohe Bay, O‘ahu, Hawai‘i. Colonies of OCN003T were pale yellow, 1–3 mm in diameter, convex, smooth and entire. The strain was heterotrophic, strictly aerobic and strictly halophilic. Cells of OCN003T produced buds on peritrichous prosthecae. Growth occurred within the pH range of 5.5 to 10, and the temperature range of 14 to 39 °C. Major fatty acids were 16 : 1!7c, 16 : 0, 18 : 1!7c, 17 : 1!8c, 12 : 0 3-OH and 17 : 0. …

The Effect Of Aging On The Blood Brain Barrier Permeability And Response To Fluoxetine Enantiomers, Ethar Arkan

Browse all Theses and Dissertations

We tested the effect of the fluoxetine enantiomers (S-fluoxetine and R-fluoxetine) versus Prozac (50:50 ratio of R- and S- fluoxetine enantiomers) and/or control on blood brain barrier (BBB) permeability in different brain regions in both male and female rats. The rats consumed orally the drug (5 mg/kg) or vehicle for a total of three days, then were injected with sterile Evans blue dye ip, at least 12 hours before euthanasia.. We see significant regional brain differences in BBB permeability (hippocampus has tighter BBB), significant differences based on the age of the animals (young rats show enhanced permeability in lower brain …

Feeding Selectivity Of An Algivore (Tropheus Brichardi) In Lake Tanganyika, Robin Richardson-Coy

Browse all Theses and Dissertations

Algivorous fish remove attached algae (periphyton) from the benthos in near shore areas of lakes. Periphyton has a complex three-dimensional structure dominated by Bacillariophyta (diatoms), Chlorophyta (green algae), and Cyanophyta (cyanobacteria). These three phyla vary in nutritional quality with diatoms providing essential fatty acids that consumers need for growth and reproduction. Selection of specific phyla may be driven by nutritional quality or it may be a function accessibility due to both mouth morphology of the fish and location of the algae in the periphyton community. I investigated whether Tropheus brichardi, an algivorous cichlid of Lake Tanganyika, selectivity feeds on …

Exploring Molecular Simulations Of A Plausible Prebiotic Reduced Phospholipid Using Hyperchem Software, Lucas Leinen, N. W. Fitch, K. L. Even, Patrick Videau, Michael Gaylor

Research & Publications

How the first cells emerged from the primordial milieu is one of the great questions in science. Biomolecular emergence scenarios abound in the literature, but the lack of bioaccessible phosphate and molecular oxygen on the primordial Earth has posed formidable challenges for deducing emergence pathways. One idea gaining wide acceptance invokes delivery of the phosphide mineral schreibersite ((Fe,Ni)3P) to Earth via meteorite impacts ca. 4.2 billion years ago, whereupon they were corroded to reduced phosphorous oxyacids and phosphonates in primordial aquatic environments. We previously proposed that these reduced phosphorus forms could readily combine with putative geochemical species in shallow mineral-rich …

Sensitivity Analysis Of Wolf Restoration In Yellowstone Nation Park Using Omnivory Models, Derek Fields

Theses, Dissertations and Capstones

In the ever-changing world of ecology, species survival often depends on approximations and measurements taken by biologists. These approximations help to ensure and predict the future of that given species. Our ecological community of interest involves wolves, elk, and berry producing shrubs within Yellowstone National Park. We use two different systems of ordinary differential equations, each increasing in complexity to model our community. In each model the predator (wolves) and consumers (elk) compete for a common resource, berry producing shrubs. We call this consumption of resources, from more than one trophic level, omnivory. We approximate each system with parameter values …

A Critical Appraisal Of Extracorporeal Photopheresis As A Treatment Modality For Acute And Chronic Graft-Versus-Host Disease, Hind Rafei, Mohamed Kharfan-Dabaja, Taiga Nishihori

Medicine Faculty Publications

Although significant advances have been made in the biologic understanding of graft-versus-host disease (GVHD) and its treatment options, GVHD remains the single most challenging obstacle to the success of allogeneic hematopoietic cell transplantation (HCT) due to high risk of disabling morbidity and mortality. Extracorporeal photopheresis (ECP) has promising effects in controlling steroid-refractory GVHD, both acute and chronic, and it has been studied extensively. Its putative immunomodulatory mechanisms, while not immunosuppressive, position ECP as an attractive treatment strategy for GVHD patients who are already receiving global immunosuppression. However, ECP is relatively underutilized due in part to limited access and time commitment. …

Journal of the Arkansas Academy of Science

Because meaningful observations of natural history are not always part of larger studies, important pieces of information often are unreported. Small details, however, can fills gaps in understanding and also lead to interesting questions about ecological relationships or environmental change. We have compiled recent observations of foods, reproduction, record size, parasites, and distribution of 30 species of fishes, new records of distribution and parasites of 2 species of amphibians, and new records of distribution, parasites, reproduction and anomalies of 11 species of mammals.

Numerous research studies have been conducted to study specific popul ations for Tay-Sachs, such as the Ashkenazi Jewish population and the Indian communit y. In my study, I intend to compare and contrast …

Patch-Occupancy Survey Of Elephant (Loxodonta Africana) Surrounding Livingstone, Zambia, David Youldon, Jackie Abell, Joanne Briffitt, Bruce A. Schulte

Biology Faculty Publications

Wild elephants represent the biggest human–wildlife conflict issue in Livingstone, Zambia. However, little is known about their movements. This survey investigated elephants’ habitat use outside a core protected and fenced zone that forms part of Mosi-oa-Tunya National Park, Zambia. Using ‘patch-occupancy’ methodology, indications of elephant presence (feeding behaviour, dung and tracks) were surveyed. The survey aimed to assist proposed future monitoring exercises by defining the geographical extent that should be considered to improve accuracy in species abundance estimates. Results were supplemented using collected indications of elephant presence from prior monitoring exercises, and during this survey. Elephant presence was confirmed up …

A Spanner In The Works: Human–Elephant Conflict Complicates The Food–Water–Energy Nexus In Drylands Of Africa, Bruce Schulte, Mwangi Githiru, Urbanus Mutwiwa, Simon Kasaine

Biology Faculty Publications

The two major conservation issues for drylands of Africa are habitat loss or degradation and habitat fragmentation, largely fromagriculture, charcoal production, and infrastructural development. A key question for management is how these landscapes can retain their critical ecological functions and services, while simultaneously supporting resilient livelihoods. It is a clear nexus question involving food (agriculture), water, and energy (fuelwood), which is complicated by human–wildlife conflicts. While these could appear disparate issues, they are closely connected in dryland forest landscapes of Africa where elephants occur close to areas of human habitation. For instance, crop failure, whether due to weather or wildlife …

Cultivating Community: Experiences Of African Refugee Gardeners, Elizabeth Willenbrink

Student Research Conference Select Presentations

Past and present, community gardening has been used as a response to poverty, a way to supplement healthy foods, and a mechanism for community involvement. For thirteen refugee families living at the Housing Authority of Bowling Green, community gardening has become a way to recreate their traditional cult ure. Based on data collected through interviews during the summer of 2016, these refugee s identified gardening as a buffer against food insecurity, providing access to both healthy a nd culturally appropriate foods. Most importantly, the interviewees identified gardening as a mechanism for support and togetherness among the city’s refugee population. M …

A Concept Analysis Of Resilience Integrating Genetics, Kosuke Niitsu, Julia F. Houfek, Cecilia R. Barron, Scott F. Stoltenberg, Kevin A. Kupzyk, Michael J. Rice

Department of Psychology: Faculty Publications

Although clinicians and researchers are interested in the phenomenon of resilience, there is no agreed-upon definition of resilience. Scientific evidence suggests that resilience is influenced by intrapersonal (e.g., personality traits) and environmental (e.g., social support) variables. A concept analysis was conducted to better understand the meaning of resilience. In this analysis, the antecedent of resilience was a potentially traumatic event; the defining attributes were ego-resiliency, emotion regulation, social support, and heredity; and the consequences were none to mild psychopathological symptoms and positive adaptation. This analysis can help nurses better understand resilience and its relationships …

Caged Oysters Still Get Scared: Predator Presence And Density Influence Growth In Oysters, But Only At Very Close Ranges, Stephen Gosnell J., Kali Spurgin, Erica A. Levine

Publications and Research

Two common forms of variation that may influence consumptive and non-consumptive effects differently are how the biomass of predators is allocated among individual predators (e.g., several small vs few large predators) and how predators are spaced throughout a community. We analyzed how varying the presence, biomass (density, size, and total biomass), and distance to crown conchs (Melongena corona) impacted growth in eastern oysters (Crassostrea virginica) grown in field conditions. The presence of predators decreased growth (new shell added and mass) and increased shell thickness in a 58-day experiment. Although these effects were more pronounced as predator …

Toward A Rapid Production Of Multivirus-Specific T Cells Targeting Bkv, Adenovirus, Cmv, And Ebv From Umbilical Cord Blood, Hema Dave, Min Luo, J.W. Blaney, Shabnum Patel, Cecilia Barese, Conrad Russell Cruz, Elizabeth J. Shpall, Catherine M. Bollard, Patrick J. Hanley

Pediatrics Faculty Publications

Umbilical cord blood (CB) has emerged as an effective alternative donor source for hematopoietic stem cell transplantation. Despite this success, the prolonged duration of immune suppression following CB transplantation and the naiveté of CB T cells leave patients susceptible to viral infections. Adoptive transfer of ex vivo-expanded virus-specific T cells from CB is both feasible and safe. However, the manufacturing process of these cells is complicated, lengthy, and labor-intensive. We have now developed a simplified method to manufacture a single culture of polyclonal multivirus-specific cytotoxic T cells in less than 30 days. It eliminates the need for a live virus …

Dense Core Vesicle Heterogeneity In Anterior Pituitary Cells, Kelly Sinak

Electronic Theses and Dissertations

Peptides, which are packaged in dense core vesicles, are an integral part of the function of the endocrine and neurological systems. The dense core vesicles function as an efficient form of peptide storage prior to regulated exocytosis. Two different dense core specific transmembrane proteins traffic different when comparted to retained prolactin cores, offering evidence of heterogeneity of vesicles within a single cell. By comparing synaptotagmin 1 and 7 distribution in male rat and lactating female lactotrophs, a distinct pattern emerges. Cells that retain prolactin cores after exocytosis correspond with those that contain synaptotagmin 1. This finding is a reversal for …

The In Vivo Effect Of Oil Palm Phenolics (Opp) In Atherogenic Diet Induced Rats Model Of Alzheimer’S Disease (Ad), Yan Wu

Wayne State University Dissertations

Alzheimer’s disease (AD) is the most common cause of dementia in the aging population. It is characterized by cognitive decline and deposition of ß-amyloid plaques in the hippocampus. It has been shown that hypercholesterolemia induced by high cholesterol diet is associated with AD development. Increased level of oxidative stress has also been observed in AD patients. An important strategy to treat or delay the impairment is based on dietary modification, using food supplements. OPP, a water soluble fraction from oil palm fruit, rich in phenolics has been found to possess significant antioxidant activities. Its beneficial effects on cardiovascular diseases, diabetes …

Utilization Of Pyrosequencing To Monitor The Microbiome Dynamics Of Probiotic Treated Poultry (Gallus Gallus Domesticus) During Downstream Poultry Processing, Vamsy Priya Guttala, Enrique G. Medrano, Joey Bray, Beatrice Clack

Faculty Publications

Antibiotic growth promoters that have been historically employed to control pathogens and increase the rate of animal development for human consumption are currently banned in many countries. Probiotics have been proposed as an alternative to control pathogenic bacteria. Traditional culture methods typically used to monitor probiotic effects on pathogens possess significant limitations such as a lack in sensitivity to detect fastidious and non-culturable bacteria, and are both time consuming and costly. Here, we tested next generation pyrosequencing technology as a streamline and economical method to monitor the effects of a probiotic on microbial communities in juvenile poultry (Gallus gallus …

Time-Course Analysis Of Gene Expression During The Saccharomyces Cerevisiae Hypoxic Response, Nasrine Bendjilali, Samuel Macleon, Gurmannat Kalra, Stephen D. Willis, A.K.M. Nawshad Hossian, Erica Avery, Olivia Wojtowicz, Mark J. Hickman

College of Science & Mathematics Departmental Research

Many cells experience hypoxia, or low oxygen, and respond by dramatically altering gene expression. In the yeast Saccharomyces cerevisiae, genes that respond are required for many oxygen-dependent cellular processes, such as respiration, biosynthesis, and redox regulation. To more fully characterize the global response to hypoxia, we exposed yeast to hypoxic conditions, extracted RNA at different times, and performed RNA sequencing (RNA-seq) analysis. Time-course statistical analysis revealed hundreds of genes that changed expression by up to 550-fold. The genes responded with varying kinetics suggesting that multiple regulatory pathways are involved. We identified most known oxygen-regulated genes and also uncovered new …
