Productivity And Composition Of Two Improved Native Pastures Under Different Grazing Managements In Uruguay, D. F. Risso, E. J. Berretta, G. Carracelas

IGC Proceedings (1977-2023)

Two improved native pastures were established by phosphoric (P) fertilisation and oversowing of: white clover (Trifolium repens) mixed with birdsfoot trefoil (Lotus corniculatus) (TbL) and annual lotus (Lotus subbiflorus) (Rin). Such pastures were evaluated during 5 years with steers at two stocking rates (High and Low) and two grazing managements (Rotational and Alternate). Presence of legumes was high and botanical changes were favourable in both pastures that evidenced good persistence. Daily liveweight gains of steers and total animal production were high in both pastures, but significantly (P≤ 0.05) higher in TbL. No significant differences …

Case Study: Degenerative Joint Disease In Canines, Zachary B. Lawrence, Rusty Rogers, Emily Schmitt Lavin

Mako: NSU Undergraduate Student Journal

Degenerative joint disease (DJD) is the gradual degeneration of cartilage in joints, resulting in pain for the affected areas. This study focused on Lacy (name changed for privacy), a 10-year-old spayed female chihuahua mix, that was clinically diagnosed for DJD and treated by Dr. Rogers over a period of 15 months. DJD is typically treated through a combination of pharmacological management, nonpharmacological treatment, and changes in lifestyle. Pharmacological treatment utilized pain medications, such as Gabapentin and Tramadol. Nonpharmacological treatment and changes in lifestyle involve methods, such as maintaining an ideal body weight, to decrease pain and increase mobility. However, during …

The Impact Of Delivery Mode On The Human Microbiome: A Global Perspective, Fizzah Qureshi, Fiza Edhi, Andrew T. Ozga

Mako: NSU Undergraduate Student Journal

The mode of childbirth in humans (vaginal or cesarean section) is considered to be one of the most influential factors in the development of gut microbiota of an infant. A microbiome is defined as a collection of microorganisms that are concentrated together in a single location or body site. The genetic material of all microbes, including bacteria, viruses, and fungi, comprises this complex ecosystem. The gut microbiota regulate digestion and strengthen the immune system in humans, helping to maintain homeostasis and are at the early stages of life, dictated by the method of delivery. Vaginal versus cesarean deliveries have increased …

Metabolic Sensing In Agrp Neurons Integrates Homeostatic State With Dopamine Signalling In The Striatum, Alex Reichenbach, Alexxai V. Kravitz, Et Al

Open Access Publications

Agouti-related peptide (AgRP) neurons increase motivation for food, however, whether metabolic sensing of homeostatic state in AgRP neurons potentiates motivation by interacting with dopamine reward systems is unexplored. As a model of impaired metabolic-sensing, we used the AgRP-specific deletion of carnitine acetyltransferase (

Immunogenicity And Protective Capacity Of A Virus-Like Particle Vaccine Against Chlamydia Trachomatis Type 3 Secretion System Tip Protein, Ct584, Everett Webster, Kyra W. Seiger, Susan B. Core, Amanda L. Collar, Hannah Knapp-Broas, June Graham, Muskan Shrestha, Sarah Afzaal, William M. Geisler, Cosette M. Wheeler, Bryce Chackerian, Kathryn M. Frietze, Rebeccah S. Lijek

Pathology Research and Scholarship

An effective vaccine against Chlamydia trachomatis is urgently needed as infection rates continue to rise and C. trachomatis causes reproductive morbidity. An obligate intracellular pathogen, C. trachomatis employs a type 3 secretion system (T3SS) for host cell entry. The tip of the injectosome is composed of the protein CT584, which represents a potential target for neutralization with vaccine-induced antibody. Here, we investigate the immunogenicity and efficacy of a vaccine made of CT584 epitopes coupled to a bacteriophage virus-like particle (VLP), a novel platform for Chlamydia vaccines modeled on the success of HPV vaccines. Female mice were immunized intramuscularly, challenged transcervically …

Detecting And Visualizing Observation Hot-Spots In Massive Volunteer-Contributed Geographic Data Across Spatial Scales Using Gpu-Accelerated Kernel Density Estimation, Guiming Zhang

Geography and the Environment: Faculty Scholarship

Volunteer-contributed geographic data (VGI) is an important source of geospatial big data that support research and applications. A major concern on VGI data quality is that the underlying observation processes are inherently biased. Detecting observation hot-spots thus helps better understand the bias. Enabled by the parallel kernel density estimation (KDE) computational tool that can run on multiple GPUs (graphics processing units), this study conducted point pattern analyses on tens of millions of iNaturalist observations to detect and visualize volunteers’ observation hot-spots across spatial scales. It was achieved by setting varying KDE bandwidths in accordance with the spatial scales at which …

Evaluating Greenhouse Gas Emissions And Climate Mitigation Goals Of The Global Food And Beverage Sector, Megan Reavis, Jenny Ahlen, Joe Rudek, Kusum Naithani

Biological Sciences Faculty Publications and Presentations

The dramatic increase in greenhouse gas (GHG) emissions by humans over the past century and a half has created an urgency for monitoring, reporting, and verifying GHG emissions as a first step toward mitigating the effects of climate change. Fifteen percent of global GHG emissions come from agriculture, and companies in the food and beverage industry are starting to set climate goals. We examined the GHG emissions reporting practices and climate goals of the top 100 global food and beverage companies (as ranked by Food Engineering) and determined whether their goals are aligned with the science of keeping climate warming …

Invertebrate Grazing On Live Turtlegrass (Thalassia Testudinum): A Common Interaction That May Facilitate Fungal Growth, Anjali D. Boyd, Nia S. Walker, Stephanie R. Valdez, Y. Stacy Zhang, Andrew H. Altieri, Vladislav Gulis, Caitlin Crain, Brian Silliman

Biology

In coastal wetlands and tropical reefs, snails can regulate foundation species by feeding on marsh grasses and hard corals. In many cases, their impacts are amplified because they facilitate microbial infection in grazer-induced wounds. Whether snails commonly graze live plants and facilitate microbial growth on plants in tropical seagrass systems is less explored. On a Belizean Caye, we examined patterns in snail-generated grazer scars on the abundant turtlegrass (Thalassia testudinum). Our initial survey showed the occurrence of snail-induced scarring on live turtlegrass blades was common, with 57% of live leaves scarred. Feeding trials demonstrated that two of five common snails …

Bovine Respiratory Microbiota Of Feedlot Cattle And Its Association With Disease, Jianmin Chai, Sarah F. Capik, Beth Kegley, John T. Richeson, Jeremy G. Powell, Jiangchao Zhao

Animal Science Faculty Publications and Presentations

Bovine respiratory disease (BRD), as one of the most common and costly diseases in the beef cattle industry, has significant adverse impacts on global food security and the economic stability of the industry. The bovine respiratory microbiome is strongly associated with health and disease and may provide insights for alternative therapy when treating BRD. The niche-specific microbiome communities that colonize the inter-surface of the upper and the lower respiratory tract consist of a dynamic and complex ecological system. The correlation between the disequilibrium in the respiratory ecosystem and BRD has become a hot research topic. Hence, we summarize the pathogenesis …

Genetic studies on telomere length are important for understanding age-related diseases. Prior GWAS for leukocyte TL have been limited to European and Asian populations. Here, we report the first sequencing-based association study for TL across ancestrally-diverse individuals (European, African, Asian and Hispanic/Latino) from the NHLBI Trans-Omics for Precision Medicine (TOPMed) program. We used whole genome sequencing (WGS) of whole blood for variant genotype calling and the bioinformatic estimation of telomere length in n=109,122 individuals. We identified 59 sentinel variants (p-value OBFC1indicated the independent signals colocalized with cell-type specific eQTLs for OBFC1 (STN1). Using a multi-variant gene-based approach, we …

Creating An Interdisciplinary Curriculum Within The Undergraduate Arts And Sciences Through Agar Art, Julie Torruellas Garcia, Kandy Lopez, Véronique Côté, Katie E. Crump

Biology Faculty Articles

Evidence-based studies on the benefits of integrating STEM into the arts are limited; however, some suggest that it can lead to improved scientific literacy and new approaches for artistic scholarship. Unfortunately, undergraduate education often creates disciplinary silos where the two are not integrated. Here, we discuss a unique collaboration between professors in the art and biology departments. Our goal was to integrate science into art courses using an agar art activity. We hypothesized that art students could effectively learn microbiology laboratory techniques and use them as novel tools for artistic practice. The activity was integrated into two to four sessions …

Microbial Cell Factory Of Baccatin Iii Preparation In Escherichia Coli By Increasing Dbat Thermostability And In Vivo Acetyl-Coa Supply, Jia-Jun Huang, Tao Wei, Zhi-Wei Ye, Qian-Wang Zheng, Bing-Hua Jiang, Wen-Feng Han, An-Qi Ye, Pei-Yun Han, Li-Qiong Guo, Jun-Fang Lin

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

Given the rapid development of genome mining in this decade, the substrate channel of paclitaxel might be identified in the near future. A robust microbial cell factory with gene dbat, encoding a key rate-limiting enzyme 10-deacetylbaccatin III-10-O-transferase (DBAT) in paclitaxel biosynthesis to synthesize the precursor baccatin III, will lay out a promising foundation for paclitaxel de novo synthesis. Here, we integrated gene dbat into the wild-type Escherichia coli BW25113 to construct strain BWD01. Yet, it was relatively unstable in baccatin III synthesis. Mutant gene dbat S189V with improved thermostability was screened out from a semi-rational mutation library …

Adoptive Parents' Lived Experience Of Bonding With Their Adopted Infants: A Phenomenological Study, Sharon M. Bator

Dissertations

Nurses' roles facilitating bonding between adoptive parents and their infants have been premised on the idea that the experience is the same as for biological parents. Developmental theorists Bowlby (1969) and Erikson (1959) maintained that bonding between an adoptive parent and their adopted child is essential for normal growth and development. The purpose of this study was to study the experience of bonding between adoptive parents and children.

Diversity And Inclusion Or Tokens? A Qualitative Study Of Black Women Academic Nurse Leaders In The United States, Kechi Iheduru-Anderson, Florence O Okoro, Shawana S Moore

College of Nursing Faculty Papers & Presentations

Severe under-representation of Black women academic nurse leaders persists in United States higher education, and a major research gap still exists regarding experiences of these leaders, and facilitators of and barriers to their success. Our objective was to examine how race and gender influence how Black women academic nurse leaders’ function in their leadership positions, how they are perceived by their peers, and how their perception of race, gender, class, and power influences diversity, equity, and inclusion initiatives in the workplace. Critical race theory was used as a guiding theory, and the study design involved narrative inquiry followed by thematic …

Myocardial Afterload Is A Key Biomechanical Regulator Of Atrioventricular Myocyte Differentiation In Zebrafish, Neha Ahuja, Paige Ostwald, Alex Gendernalik, Elena Guzzolino, Letizia Pitto, David Bark, Deborah M Garrity

Open Access Publications

Heart valve development is governed by both genetic and biomechanical inputs. Prior work has demonstrated that oscillating shear stress associated with blood flow is required for normal atrioventricular (AV) valve development. Cardiac afterload is defined as the pressure the ventricle must overcome in order to pump blood throughout the circulatory system. In human patients, conditions of high afterload can cause valve pathology. Whether high afterload adversely affects embryonic valve development remains poorly understood. Here we describe a zebrafish model exhibiting increased myocardial afterload, caused by vasopressin, a vasoconstrictive drug. We show that the application of vasopressin reliably produces an increase …

Serpinb3 (Scca1) Inhibits Cathepsin L And Lysoptosis, Protecting Cervical Cancer Cells From Chemoradiation, Songyan Wang, Cliff J Luke, Stephen C Pak, Victoria Shi, Liyun Chen, Jonathan Moore, Arlise P Andress, Kay Jayachandran, Jin Zhang, Yi Huang, Marina Platik, Anthony A Apicelli, Julie K Schwarz, Perry W Grigsby, Gary A Silverman, Stephanie Markovina

Open Access Publications

The endogenous lysosomal cysteine protease inhibitor SERPINB3 (squamous cell carcinoma antigen 1, SCCA1) is elevated in patients with cervical cancer and other malignancies. High serum SERPINB3 is prognostic for recurrence and death following chemoradiation therapy. Cervical cancer cells genetically lacking SERPINB3 are more sensitive to ionizing radiation (IR), suggesting this protease inhibitor plays a role in therapeutic response. Here we demonstrate that SERPINB3-deficient cells have enhanced sensitivity to IR-induced cell death. Knock out of SERPINB3 sensitizes cells to a greater extent than cisplatin, the current standard of care. IR in SERPINB3 deficient cervical carcinoma cells induces predominantly necrotic cell death, …
