Karbala International Journal of Modern Science

    The present investigation aims to evaluate the effects of acid and laser surface treatments on the surface characteristics, biocompatibility, and osseointegration of functionally graded implants fabricated from a Co–Cr–Mo–Ti/HA alloy. The implant surfaces were modified using either an Nd: YAG laser or hydrochloric acid (HCl), while untreated implants served as controls. Atomic force microscopy (AFM) showed that the acid-treated surface exhibited the highest mean surface roughness (Sa) of 58.10 ± 0.24 nm compared to the laser-treated surface (42.64 ± 0.83 nm) and the untreated surface (37.73 ± 0.89 nm). The MTT assay also demonstrated a favourable cellular response on the …

Bryophyte Community Composition In A Second-Order Tropical Stream At The Luquillo Experimental Forest, Puerto Rico, Cecilia Sahnow, Jean P. González-Crespo, Amelia Merced

Biology Faculty Publications and Presentations

Streams are important ecosystems that harbor a high diversity of plant species including bryophytes. Studies suggest streams can function as refugia and/or corridors that buffer against the effects of disturbances. In this study, we sampled five sites along a second-order tropical stream in the Luquillo Experimental Forest. We described the riparian bryophyte community composition in conjunction with the physical structure of the stream to understand what environmental factors influence bryophyte composition in the stream. We identified 56 bryophytes, 33 liverworts and 23 mosses; and we recorded cyanobacteria associated with over half of the species of bryophytes. Rocks were the most …

Nasa’S Ecostress Satellite Reveals Widespread Midday Depression In Ecosystem Evapotranspiration, Jingyi Bu, Jingfeng Xiao, Joshua B. Fisher, Yiqi Luo

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Plants often exhibit a midday depression in water use (i.e., transpiration), reflecting a constraint on their ability to sustain maximum water transport, which may occur at the cost of reduced photosynthesis. Eddy covariance observations and geostationary satellites cannot quantify this widespread phenomenon globally while resolving fine-scale spatial variability. Using evapotranspiration measurements from the ECOsystem Spaceborne Thermal Radiometer Experiment on Space Station (ECOSTRESS) and machine learning, we quantify the global distribution of midday depression in evapotranspiration. Midday depression primarily occurs during peak-growing seasons in temperate zones and dry periods in the tropics, with a morning shift of the peak evapotranspiration time …

Soil amendments may facilitate restoration; however, the practical usefulness of techniques such as applications of whole soil and leaf mulch remains relatively unclear.

Objectives: We assessed whether increasing species richness and legume content in seed mixes enhances prairie restoration success and examined how soil amendments interact with seed mix composition to influence cover, species richness, diversity, and legume establishment.

Methods: We conducted a field experiment on a 12-ha post-agricultural site in Ohio, U.S.A. Twenty 50 × 50 m plots received one …

Hydrogels For Local Drug Delivery In Biofilm-Associated Periprosthetic Joint Infection: Current Progress And Future Directions, Karolina Kraus, Pawel Mikziński, Bindu Subhadra, Emil Paluch

Faculty Publications - Biological Sciences

Periprosthetic joint infection (PJI) remains one of the most serious complications of arthroplasty, largely due to the formation of microbial biofilms on implant surfaces. Biofilm-associated infections exhibit increased tolerance to antimicrobial therapy and host immune responses, making eradication difficult and often requiring repeated surgical interventions. Consequently, there is a growing need for effective local therapeutic strategies capable of delivering high concentrations of antimicrobial agents directly to the site of infection while minimizing systemic toxicity. Hydrogels have emerged as promising drug delivery platforms for the management of biofilm-associated PJI. Their biocompatibility, injectability, high water content, and tunable physicochemical properties enable controlled …

Three-Dimensional Cell And Nuclear Geometries Inform Tissue Level Fluid Mechanics During Epithelial Remodeling, Liam Joseph Russell

Electronic Theses and Dissertations

During epithelial remodeling, mechanical and molecular programs must coordinate to drive the cell shape changes that enable new tissue topologies. Dynamic morphogenesis requires epithelia to preferentially exhibit solid- or fluidlike properties depending on developmental and biophysical constraints. Convergent extension in the Drosophila germband epithelium is one such remodeling event, during which the lateral ectoderm lengthens by two-fold along the primary body axis while concomitantly shortening orthogonally. This process is an incredibly dynamic and attractable system for studying tissue morphogenesis mechanics in vivo.

Germband extension is driven by oriented cell intercalation through T1 transitions, where cells directionally interdigitate with one another …

Investigating Caveolar Systems: Spatiotemporal Quantification Of Caveolin-1 And The Mechanotransducive Function Of Ehd2, Jasper Stanae Farrington

Electronic Theses and Dissertations

Caveolae are 50-100nm cholesterol rich flask shaped invaginations found in many differentiated cells. Namely, these structures have been seen to be abundant in endothelial cells where they are involved in many signaling contexts. However, under mechanical stress, the characteristics of caveolae alter, flattening to increase membrane compliance, while displaced proteins can shift from structural roles to mechanosensitive signaling functions. Caveolin-1 (Cav1) is the principal protein required for Caveolar formation while Eps15 Homology Domain Containing Protein 2 (EHD2) is a membrane ATPase that acts to stabilize caveolae at the surface. Despite their emerging importance, understanding the organization and dynamic regulation of …

Exploring Foundations Of Animal Host-Microbe Interactions In A Freshwater Sponge, Jacob S. Pawley

Electronic Theses and Dissertations

The most ancient eukaryotic immune defense mechanisms evolved in unicellular species. Multicellular eukaryotes, however, expanded these mechanisms to meet challenges unique to multicellular life, including barrier formation, long-distance cell signaling, and coordinated responses that eliminate microbial threats while minimizing damage to the host. As such, animal immune signaling pathways are exceptionally intricate and diverse. Though, most of what is understood about animal host–microbe interactions stems from a small handful of model systems. Here, I evaluate host–microbe interactions and innate immunity in sponges using the highly tractable freshwater sponge, Ephydatia muelleri. I report the discovery of an external host-derived matrix …

Identification And Characterization Of Novel Immune Modulating Genes In Parkinson's Disease, Kathleen Chaundy Paul Murphy

Dartmouth College Ph.D Dissertations

Parkinson’s disease (PD) is a progressive age-related neurodegenerative disorder characterized by both motor and non-motor symptoms. The poorly understood prodromal period, decades-long progression, and disease-phenotype heterogeneity continue to impede the development of preventive and curative therapies. A growing appreciation of immune system changes during the progression of PD suggests that evaluating peripheral immune cells may help identify signatures relevant to disease etiology. We aimed to expand our understanding of the peripheral immune compartment in PD via two lines of investigation: (1) by employing single-cell RNA sequencing to profile the transcriptomes of peripheral blood mononuclear cells (PBMCs) from a cohort of …

Effects Of Intensive Exercise On The Blood Chemistry Of Fighting Bulls In Southern Thailand, Siriwat Wasiksiri, Pratthana Yongsakulchai, Wichaya Thongtako, Paradorn Muangnil, Teepakorn Adulkasem

The Thai Journal of Veterinary Medicine

Bullfighting is a cultural activity in southern Thailand. Bulls walk and undergo intensive exercise before competition. In the arena, winners are determined by their opponents' surrender, so bulls do not die after fighting. However, there are very few studies on organ injuries in living bulls during these activities. This study compared the effects of walking and intensive exercise on complete blood count (CBC) and blood chemistry. Blood parameters of 14 Thai fighting bulls aged over 6 years, regularly trained for walking and intensive exercise, were measured and analyzed using a paired t-test or Wilcoxon signed-rank test. Eosinophils decreased significantly after …

The Posture Of Recovery; A Quantitative Analysis Of Post-Exercise Heart Rate Restorateion In College Athletes, Matthew Scott Ferriter

Doctoral Dissertations and Projects

Heart rate recovery (HRR) has been frequently used as a noninvasive indicator of autonomic reactivity following high-intensity exercise. However, limited research has explored the effects of post-exercise body posture (PEBP) on HRR following acute bouts of high-intensity exercise in collegiate athletes. The purpose of this quantitative repeated-measures experimental study was to investigate if recovery posture (supine [SUP]; tripod [TRI]; standing upright [SU]) affected HRR during the first five minutes following a standardized high-intensity interval training (HIIT) session. Thirty-seven collegiate athletes completed three total testing sessions. Participants completed all three recovery posture conditions in a randomized order. Heart rate (HR) was …

Cells And Networks In Flux: Rethinking Ontogenesis And Pathogenesis, Mark L. Tykocinski

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

Organ and tissue functions emerge from the coordinated activity of cell networks. Therapeutics that act on pathogenic cell networks, modulating their cellular interplay, follow naturally. Over several decades, our laboratory has developed a series of approaches for rewiring cell networks, culminating in a class of cell surface-directed signal converter proteins (SCPs) that do so by modulating juxtacrine and autocrine signaling in and among their nodal cells. A first such SCP has now produced encouraging clinical data for cancer immunotherapy. Yet, these early network-directed fusion proteins rest on a deliberately simplified picture: discrete end-cell types plugged into graphically tractable networks. That …

Evaluation Of Tactile Cueing Embedded In An Aviation Headset On Pilot Altitude Control, Nicholas D. Wilson, Jessica Van Bree, Matthew Cleveland, Sunny Charakuru, Thomas Petros, Richard Ferraro, Kouhyar Tavakolian

Journal of Aviation/Aerospace Education & Research

This study evaluated the effectiveness of tactile cueing integrated into a pilot’s headset on pilot altitude control during simulated instrument conditions. Pilots typically rely on visual and auditory inputs to maintain situational awareness, but in high-workload or instrument meteorological conditions (IMC), these channels can become overloaded. One underutilized alternative for alerting is a tactile cueing apparatus. Using an X-Plane simulation of a Piper Archer equipped with a G-1000 avionics suite, 39 FAA-certified pilots flew two precision approaches. The experimental group (n = 20) received haptic cues via ear seal-embedded tactors when deviating from assigned altitude or glideslope. The control group …

Relationships Between Lower Body Anthropometrics And Vertical Force-Velocity Profiles In Collegiate American Football Players, Nicholus Adam Despot

Doctoral Dissertations and Projects

The study examined the relationships between lower-body anthropometric characteristics and vertical force-velocity profiles in collegiate American football players. Although the use of force-velocity profiling has increased significantly in recent years, there has been limited research on the association between structural features and key mechanical outputs. A sample of 16 NAIA football players was used to examine how skeletal breadths, girths, and derived ratios relate to key force-velocity metrics. Anthropometric variables were collected using ISAK standards, while force-velocity profiles were obtained through a series of loaded squat jumps on a force platform. Mean propulsive force, velocity and power were used to …

Developing Field And Spaceflight Microscopy, Nikki Johnston

Dissertations and Theses

Designing for spaceflight favors the reduction of unnecessary features and cost-cutting, whether thisbe computation, hardware, or procedure. Resources are spent toward fortification and mission success over convenience. Such design goals paired with the relatively smaller budgets of academia lead us to do as much as we can in-house and use open-source as much as we can without compromising mission success. We also believe that thoroughly testing technology in extreme environments on earth is necessary for the success of a flight instrument. We focus on microscopy for life detection. I have spent my time here learning methods of hand-building microscopes to …

The Influence Of Circadian Rhythm Disruption And Apoe4 On The Prognosis And Progression Of Alzheimer’S Disease, Kayla Bradby

Graduate Student Dissertations, Theses, Capstones, and Portfolios

Alzheimer’s disease is characterized by cognitive decline and memory loss and is the most common form of dementia. Genetic factors such as apolipoprotein E have been significantly associated with AD development and progression, most specifically the APOE4 isoform. Emerging evidence has shown that when the body’s circadian rhythm, the 24-hour dark/light cycle, is disrupted, the potential to develop a neurodegenerative disease such as AD increases. The purpose of this literature review is to examine the relationship between AD, circadian rhythm, and the APOE isoforms. This review puts a particular emphasis on the APOE4 isoform, as it has been shown to …

The Invisible Crop: Harnessing Root System Architecture In Heirloom Collards For Climate-Resilient Urban Agriculture, Vincent Antonio Brazelton

Arts & Sciences Graduate Student Theses and Dissertations

Growing food in urban spaces often means working within variable, resource-limited environments, creating a need for crops that can withstand heterogeneous growing conditions. Heirloom collards (Brassica oleracea var. viridis) are known for their aboveground diversity and cultural importance, but much less is known about the variation that exists belowground. This dissertation examines root system architecture (RSA) diversity across 19 historically underutilized heirloom collard accessions using a multi-scale phenotyping approach that includes controlled gel-based imaging of seedlings and 2D imaging of mature field-grown root systems. Across both seedling and mature stages, heirloom collards showed substantial variation in RSA. These differences revealed …

Mindful Parenting And Toddlers' Food Responsiveness: The Role Of Controlling Feeding Practices, Qingyu Jiang, Holly Wilhite, Natalie A. Williams, Dipti A. Dev, Caron A. C. Clark, Pearl Avari, Sarah B. Ladd

Journal of Extension

Controlling feeding practices may negatively impact children's eating behaviors. Mindful parenting may offer a promising way to reduce the use of these practices. This study examined the mediating role of pressuring children to eat and using food as a reward in the association between mindful parenting and toddlers' food responsiveness. Results indicated that higher levels of mindful parenting were associated with lower pressuring to eat, which was related to lower food responsiveness in toddlers. The results may inform Extension professionals providing mindfulness strategies for mothers of young children to improve feeding practices, ultimately reducing children's unhealthful eating behaviors.

Traumatic brain injury (TBI) is associated with cardiovascular dysfunction that worsens clinical outcomes, yet the underlying mechanisms are poorly under stood. Clinical studies are limited by heterogeneity, highlighting the need for con trolled experimental models. Controlled cortical impact (CCI) provides precise control of injury severity, and invasive pressure- volume (PV) loop analysis allows detailed hemodynamic assessment. Adult male Wistar rats underwent sham op eration or mild or severe CCI- induced TBI. PV- loop assessment and transtho racic echocardiography were performed at 8 or 24 h after TBI or sham. Serum epinephrine (EPI) and norepinephrine (NE) were quantified by ELISA. At …

Host-Pathogen Dynamics Underpinning Staphylococcus Aureus Growth During Intracellular Osteoclast Infection, Luke D. O'Connor

WUSM Theses and Dissertations – All Programs

Bone infection is most commonly caused by the gram-positive bacterium Staphylococcus aureus. It has myriad ways in which it can circumvent or subvert killing by the host or antibiotics. Intracellular infection is one such niche that is protective from immune and antibiotic attack. In 2019, Krauss and colleagues discovered that infected osteoclasts (OCs) allow S. aureus to replicate intracellularly. There they found that the ability of S. aureus to grow inside the cell was tied to OC differentiation. The magnitude of overnight bacterial expansion positively correlated with OC maturity and duration cultured with the osteoclastogenic factor RANK ligand (RANKL). Bacterial …
