The Pros And Cons Of Beta Blockers: Doping In Music Performance, University Of Denver Nov 2023

The Pros And Cons Of Beta Blockers: Doping In Music Performance, University Of Denver

Musicology and Ethnomusicology: Student Scholarship

When performing in front of an intimidating panel of judges, an audience, or peers, many musicians faces a common problem that’s not talked about often: music performance anxiety. In this current time, every musician at least knows someone that takes a type of drug that enhances their music performance and gets rid of their anxiety. However, there’s been some controversies in using drugs in music competitions and auditions, leading in the continuous practice of drug abuse, questioning ethically what’s right and what’s wrong, and the suspicion in cheating. In this paper will examine the pros and cons of beta blockers, …

Spectrum-Enhanced Trca (Se-Trca): A Novel Approach For Direction Detection In Ssvep-Based Bci, Amirmohammad Mijani, Mohammad Norizadeh Cherloo, Haoteng Tang, Liang Zhan

Computer Science Faculty Publications

The Steady State Visual Evoked Potential (SSVEP) is a widely used component in BCIs due to its high noise resistance and low equipment requirements. Recently, a novel SSVEP-based paradigm has been introduced for direction detection, in which, unlike the common SSVEP paradigms that use several frequency stimuli, only one flickering stimulus is used and it makes direction detection very challenging. So far, only the CCA method has been used for direction detection using SSVEP component analysis. Since Canonical Correlation Analysis (CCA) has some limitations, a Task-Related Component Analysis (TRCA) based method has been introduced for feature extraction to improve the …

Paternity And Child Welfare, Nafees Alam Nov 2023

Paternity And Child Welfare, Nafees Alam

Social Work Faculty Publications and Presentations

This theoretical and conceptual analysis, rooted and organized by frameworks and empirical literature, aims to explain biases against fathers in the United States’ family court system. Positive paternal involvement has been shown to be correlated with positive child outcomes, placing an emphasis not just on quantity, but quality as well. Despite these findings, fathers are societally expected to be less involved than mothers. Fathers are also in positions to be held financially hostage even when alternatives to pregnancy are legally accessible, suggesting that paternal financial contributions are viable substitutes for paternal involvement. The court of law and the court of …


Biological And Environmental Factors May Affect Children’S Executive Function Through Motor And Sensorimotor Development: Preterm Birth And Cerebral Palsy, Iryna Babik, Andrea B. Cunha, Sudha Srinivasan Nov 2023

Biological And Environmental Factors May Affect Children’S Executive Function Through Motor And Sensorimotor Development: Preterm Birth And Cerebral Palsy, Iryna Babik, Andrea B. Cunha, Sudha Srinivasan

Psychological Sciences Faculty Publications and Presentations

Disruptive biological and environmental factors may undermine the development of children’s motor and sensorimotor skills. Since the development of cognitive skills, including executive function, is grounded in early motor and sensorimotor experiences, early delays or impairments in motor and sensorimotor processing often trigger dynamic developmental cascades that lead to suboptimal executive function outcomes. The purpose of this perspective paper is to link early differences in motor/sensorimotor processing to the development of executive function in children born preterm or with cerebral palsy. Uncovering such links in clinical populations would improve our understanding of developmental pathways and key motor and sensorimotor skills …

Anti Cancer Activity Of Rhus Coriaria (Sumac) Against 5-Fluorouracil-Resistant Colorectal Cancer Cells, Zohra Nausheen Nizami

Theses

Colorectal cancer (CRC) is the second leading cause of cancer-related deaths, both worldwide and in the UAE. 5-Fluorouracil (5-FU), a pyrimidine analogue, is a chemotherapeutic agent that is an integral component of chemotherapy regimens for CRC treatment. However, 5-FU resistance (intrinsic and/or acquired) inhibits their clinical efficacy. In recent years, there has been a growing popularity for plant-based cancer therapeutics, specifically using phytochemical compounds. Rhus coriaria (Sumac) is a Mediterranean plant whose fruits are used as a spice and medicinal herb. Extracts of Rhus coriaria fruits (RCE) have been reported to exhibit anti-cancer activity against breast cancer and CRC. In …

Women of African descent have the highest breast cancer mortality in the United States and are more likely than women from other population groups to develop an aggressive disease. It remains uncertain to what extent breast cancer in Africa is reminiscent of breast cancer in African American or European American patients. Here, we performed whole-exome sequencing of genomic DNA from 191 breast tumor and non-cancerous adjacent tissue pairs obtained from 97 African American, 69 European American, 2 Asian American, and 23 Kenyan patients. Our analysis of the sequencing data revealed an elevated tumor mutational burden in both Kenyan and African …


The Evaluation Of Calsporin And Imw50 On Production Performance, Microbial Population, And Immune Function Of The Laying Hen, Kayla N. Kleist Nov 2023

The Evaluation Of Calsporin And Imw50 On Production Performance, Microbial Population, And Immune Function Of The Laying Hen, Kayla N. Kleist

Master's Theses

The use of antibiotics as growth promotors in the food animal industry has led to the generation of antibiotic resistant microorganisms, which are a major health risk to humans. Therefore, bans and limitations, including the FDA’s veterinary feed directive, have been placed on the use of antibiotics as growth promotors, and there has been a push to find an adequate alternative. In the laying hen, probiotics and/or prebiotics have shown promise as they help promote the colonization of beneficial bacteria in the GI tract of the host, increase feed efficiency, increase egg production, and provide protection against pathogenic bacteria.

Emulating Evolutionary Principles For Agriculture: Designing A Biomimetic Vertical Garden By Mimicking Tracheophyte Evolution, Earl M. Riddell Nov 2023

Emulating Evolutionary Principles For Agriculture: Designing A Biomimetic Vertical Garden By Mimicking Tracheophyte Evolution, Earl M. Riddell

Honors Theses

Biodiversity, particularly in the world’s equatorial regions, is under threat from human industry. Among the most daunting problems facing these biomes is that of the food industry’s continual expansion into what was once rainforest. Expansive monoculture (large cultivated swaths of a single crop species) are the primary threat to tropical biodiversity. This method of agriculture is harmful because it requires the clearing of land that once supported thousands of species in order to replace it with rows of a single crop. If more plants could be grown in a smaller horizontal square footage, farms need not rely so heavily on …

A Membrane Protein Of The Rice Pathogen Burkholderia Glumae Required For Oxalic Acid Secretion And Quorum Sensing, Asif Iqbal, George Nwokocha, Vijay Tiwari, Inderjit K. Barphagha, Anne Grove, Jong Hyun Ham, William T. Doerrler

Faculty Publications

Bacterial panicle blight is caused by Burkholderia glumae and results in damage to rice crops worldwide. Virulence of B. glumae requires quorum sensing (QS)-dependent synthesis and export of toxoflavin, responsible for much of the damage to rice. The DedA family is a conserved membrane protein family found in all bacterial species. B. glumae possesses a member of the DedA family, named DbcA, which we previously showed is required for toxoflavin secretion and virulence in a rice model of infection. B. glumae secretes oxalic acid as a “common good” in a QS-dependent manner to combat toxic alkalinization of the growth medium …

Faculty Publications

Managed honey bee (Hymenoptera: Apidae: Apis mellifera Linnaeus) hives require frequent human inputs to maintain colony health and productivity. A variety of plant natural products (PNPs) are delivered via feeding to control diseases and reduce the use of synthetic chemical treatments. However, despite their prevalent use in beekeeping, there is limited information regarding the impact of ingested PNPs on bee health. Here, we tested the effects of different essential oils and propolis extracts on honey bee life span, nutrient assimilation, xenobiotic detoxification, and gut microbiota abundance. Brazilian propolis extract lengthened worker life span, while the other PNPs (Louisiana propolis extract, …

Weight And Protozoa Number But Not Bacteria Diversity Are Associated With Successful Pair Formation Of Dealates In The Formosan Subterranean Termite, Coptotermes Formosanus, Junyan Chen, Garima Setia, Li Hsiang Lin, Qian Sun, Claudia Husseneder

Faculty Publications

New colonies of Formosan subterranean termites are founded by monogamous pairs. During swarming season, alates (winged reproductives) leave their parental colony. After swarming, they drop to the ground, shed their wings, and male and female dealates find suitable nesting sites where they mate and become kings and queens of new colonies. The first generation of offspring is entirely dependent on the nutritional resources of the founder pair consisting of the fat and protein reserves of the dealates and their microbiota, which include the cellulose-digesting protozoa and diverse bacteria. Since termite kings and queens can live for decades, mate for life …


Oxidative Stress In Health And Disease, V. Prakash Reddy Nov 2023

Oxidative Stress In Health And Disease, V. Prakash Reddy

Chemistry Faculty Research & Creative Works

Oxidative stress, resulting from the excessive intracellular accumulation of reactive oxygen species (ROS), reactive nitrogen species (RNS), and other free radical species, contributes to the onset and progression of various diseases, including diabetes, obesity, diabetic nephropathy, diabetic neuropathy, and neurological diseases, such as Alzheimer's disease (AD), amyotrophic lateral sclerosis (ALS), and Parkinson's disease (PD). Oxidative stress is also implicated in cardiovascular disease and cancer. Exacerbated oxidative stress leads to the accelerated formation of advanced glycation end products (AGEs), a complex mixture of crosslinked proteins and protein modifications. Relatively high levels of AGEs are generated in diabetes, obesity, AD, and other …

Adipocyte Stat5 (Signal Transducer And Activator Of Transcription 5) Is Not Required For Glucocorticoid-Induced Metabolic Dysfunction, Innocence Harvey, Allison J. Richard, Tamra M. Mendoza, Jacqueline M. Stephens

Division of Basic Science Faculty Publications

Excess glucocorticoid (GC) signaling in adipose tissue is a key driver of insulin resistance and hepatic steatosis, but underlying mechanisms have not been fully elucidated. Signal transducer and activator of transcription 5 (STAT5) signaling in adipocytes has also been implicated in the progression of similar metabolic disturbances. Although STAT5 has been shown to interact with the glucocorticoid receptor (GR) in many cell types including adipocytes, the relevance of the STAT5/GR complex has not been investigated in adipocytes. Adult male and female adipocyte-specific STAT5 knockout (STAT5AKO) and floxed mice were given corticosterone (CORT) or vehicle in their drinking water for 1 …

Quantitative Trait Loci, Candidate Genes, And Breeding Lines To Improve Salt Tolerance At The Flowering And Seedling Stages In Rice, Rajat Pruthi, Sandeep Chapagain, Sapphire Coronejo, Lovepreet Singh, Prasant Kumar Subudhi

Faculty Publications

Salinity is a major environmental constraint that limits growth and productivity of rice all over the world. Although rice plants are vulnerable to salt stress at both seedling and flowering stages, genetic dissection of salt tolerance at the flowering stage is challenging due to non-uniformity of stress application at the appropriate growth stage. The present study was conducted to identify quantitative trait loci (QTLs) and candidate genes associated with the flowering stage salt tolerance and compare with those associated with the seedling stage using a high-resolution genetic map. A population of advanced generation introgression lines with uniform flowering time was …

Division of Basic Science Faculty Publications

Background: The obesity pandemic has worsened global disease burden, including type 2 diabetes, cardiovascular disease, and cancer. Metabolic/bariatric surgery (MBS) is the most effective and durable obesity treatment, but the mechanisms underlying its long-term weight loss efficacy remain unclear. MBS drives substrate oxidation that has been linked to improvements in metabolic function and improved glycemic control that are potentially mediated by mitochondria—a primary site of energy production. As such, augmentation of intestinal mitochondrial function may drive processes underlying the systemic metabolic benefits of MBS. Herein, we applied a highly sensitive technique to evaluate intestinal mitochondrial function ex vivo in a …
