Β-Glucan Mitigates Valproic Acid-Induced Hepatorenal Toxicity In Rats, Maha Mohammad Almutairi, Hussein Mohammad Ali, Mohamed Abdelbakky, Ahmad Hamad Alhowail

Saudi Toxicology Journal

Valproic acid (VPA) is a common medication used to treat epilepsy, known for its broad-spectrum efficacy but also associated with hepatotoxicity and metabolic disturbances. β-glucan, a natural polysaccharide with hepatoprotective properties, may mitigate druginduced liver damage. The study sought to assess hepatorenal toxicity of VPA and investigate the potential protective and therapeutic effects of β-glucan. Forty male rats were randomly distributed into four groups. The treated group received VPA (500 mg/kg), β-glucan (50 mg/kg), or combinations for 14–21 days via intraperitoneal injection. Serum biochemical parameters (ALT, AST, ALP, urea, creatinine, lipids) were measured. Histopathological evaluation of hepatic tissue was performed. …

Effects Of Tubulin-Binding Medications On Microplastic Uptake And Cyotoskeletal Functionality Across Diverse Cell Types, Alejandra D. Favela Santos

Posters - 2026

• Microtubules are composed of of a- and b- tubulin heterodimers, vital for cell structure, shape, and intracellular transport • Microtubules are also useful as they separate chromosomes during cell division • Microplastics (< 5 mm) are considered a health threat and have been found throughout the whole body (1) o In several studies, microplastics have been correlated to higher rates cardiorespiratory issues, endocrine disruption, and cancer (1) • Tubulin-binding medications are widely used as chemotherapeutic agents as they are known for disrupting cell division and targeting tubulin (2,3) o In this study, these medications were used to determine whether microtubules play a role in microplastic uptake § Colchicine typically binds to tubulins and arrests polymerization and growth § Nocodazole disrupts polymerization and prevents spindle formation § Vinblastine inhibits microtubule assembly and disruptions miotic spindle formation.

• The purpose of this study was to determine if different concentrations of tubulin-binding medications affect microplastic uptake o C2C12, RAW 264.7, and MOVAS cell lines were used to evaluate whether these changes are cell type specific 

If microtubule dynamics are disrupted, microplastic uptake can be affect in a concentration-dependent and cell type- specific manner.

Impact Of Ashwagandha Treatment On Cytokine Production And Macrophage Differentiation Into Thp-1 Cells, Betsi Diaz Chavarin, Aditi Kumar

Posters - 2026

Inflammation is a critical biological response that enables the immune system to react to infections, injuries, or stressful situations. However, chronic or excessive inflammation can lead to tissue damage and contribute to a wide range of diseases, including neurodegenerative disorders, metabolic syndromes, and immune dysregulation. 3,4 Interleukin-1 beta (IL-1β) is a key pro-inflammatory cytokine that plays a central role in initiating and amplifying the immune response. 1,2 It is primarily produced by activated monocytes and macrophages in response to stimuli such as pathogens or stress signals. In addition, IL-1β acts on the hypothalamus to induce fever, which creates an environment …

Take A Hit? Take A Hit: Quantifying Cell Death In E-Cigarette Exposed Bronchial Epithelial Cells Following Cards Toxin Treatment, Truman Havrda, Hannah Jiron, Sierra Trevino

Posters - 2026

The rapid rise of e-cigarette use among young adults has created a significant public health challenge, as the popularity of "vaping" has grown faster than our understanding of its long term cellular consequences. Current research indicates that e-cigarette vapor (ECV) induce high levels of oxidative stress and impair the lungs' ability to clear bacterial pathogens. Furthermore, ECV exposure upregulates specific receptors on the surface of airway cells, essentially making it easier for bacteria to adhere to and infect the lungs. While we know that both e-liquids and vapor trigger inflammatory responses and cytotoxicity, there is limited data on how these …

Imidacloprid Effects On The Survival And Cutaneous Microbiome Of Northern Leopard Frogs, Evelyn Margaret Osterloo

Honors Thesis

Amphibians are experiencing population declines due to habitat loss, climate change, and diseases, particularly chytridiomycosis caused by the fungus Batrachochytrium dendrobatidis. Protection from this fungal infection stems from the cutaneous microbiome. Pesticides have been shown to affect amphibians in a variety of ways, including reducing survival, locomotor performance, and accumulation in body tissues. Pesticides may also lead to changes in the cutaneous microbiome affecting amphibians who rely on these organisms as an anti-Bd defense mechanism. To investigate the effect of imidacloprid, a neonicotinoid insecticide, Northern Leopard frogs (Lithobates pipiens) were subjected to sublethal concentrations (control = …

"I Need Help!": Can Ashwagandha Reduce Inflammation-Driven Oxidative Stress Without Inducing Cytotoxicity In Macrophages?, Caitlyn Pinaga

Posters - 2026

Ashwagandha has been shown to reduce inflammation in humans by lowering pro-inflammatory cytokines and oxidative stress markers, helping regulate immune responses. It is commonly used to support conditions linked to chronic inflammation, such as stress-related disorders, arthritis, and metabolic imbalance. THP-1 macrophages are a part of the body's immune response to inflammation. While they produce a lot of different responses to inflammation, one of them is the production of Reactive Oxygen Species (ROS). N-acetylcysteine (NAC) is established to be a powerful antioxidant and is used as a positive control. My study aims to understand how ashwagandha, a popular supplement, affects …

Virginia Journal of Science

Urban agriculture broadly describes food and plant cultivation in metropolitan areas. While biodiversity is thought to support ecosystem health and resilience, the relationship between above-ground and below-ground diversity has been understudied in urban green spaces. This study examines plant, animal, bacterial, and fungal diversity across three distinct urban habitats: a turf lawn, a forb garden, and a farming space. Using bacterial 16S rRNA and fungal ITS2 sequencing, soil nutrient analyses, and surveys of vegetation and wildlife, we connect diverse philosophies in urban agriculture to their role in advancing community diversity and ecosystem function. We found that different urban gardens support …
