Exploring Molecular And Morphological Diversity Of Ostracoda: A Combined Approach Based On Coi Sequences And Morphological Characters, Serdar Di̇nç, Serap Mutun, Okan Külköylüoğlu

Turkish Journal of Zoology

Ostracods are diminutive aquatic invertebrates with a broad geographical distribution  across a diverse range of aquatic habitats, including lentic and lotic freshwater  environments as well as marine waters. Due to their sensitivity to environmental  changes, ostracods are valuable tools in biodiversity monitoring, providing a link to  past, present, and future ecological conditions. Despite the significance of classical  taxonomic studies in species identification, molecular approaches remain  underutilized in ostracod research, representing an area of potential growth for  advancing our understanding of this diverse group. Thus, molecular studies in  ostracods have the potential to greatly enhance our understanding of morphology,  ecological variation …

Spatial And Temporal Variability Of Mayfly Communities (Insecta: Ephemeroptera) In Mountainous And Semimountainous Rivers Of The Western Aegean Basin, Biljana Rimcheska, Yanka Vidinova

Turkish Journal of Zoology

Mayflies are among the most abundant benthic invertebrates inhabiting natural lotic  freshwater systems. Their assemblages vary with environmental, geographical, and  hydrological conditions along altitudinal gradients and under different types of  watershed disturbance. The main objective of this study was to analyze the  composition and β-diversity of mayflies across three river watersheds and to assess  how these assemblages differ among them. We collected biological and  environmental data from 38 sampling sites distributed across the three river  watersheds. We hypothesized that mayfly assemblages would vary with  environmental gradients on both spatial and temporal scales; specifically, we  expected pristine streams to exhibit higher …

Towards The Assessment Of E-Flows: A Fish-Based Approach For The Tiber River Basin (Central Italy), Antonella Carosi, Francesca Lorenzoni, Fatemeh Zarei, Rachele Brustenga, Lucio Di Matteo, Daniela Valigi, Corrado Cencetti, Carlo Cardellini, Stefano Casadei, David Cappelletti, Massimo Lorenzoni

Turkish Journal of Zoology

Estimating ecological flows (EFs) in rivers is crucial for meeting the Water Framework  Directive (WFD) 2000/60/EC goals. To develop an EF model, it is  essential to use biological indicators to reliably record the impacts of human-induced  alterations on aquatic ecosystems. The adaptability of fish to annual flow variability  makes them a significant biological quality element (BQE). Consequently, using fish  as bioindicators is a powerful tool for assessing the impact of changes in the  hydrological regime on the natural communities within a river system. The new index  of the ecological status of fish communities (NISECI) is a methodology developed in  Italy …

Chlorella Vulgaris Measurements Using Full-Spectrum Goniometer For Optically Complex Inland Water Monitoring, Pinar Gürbüzer, Uğur Murat Leloğlu

Turkish Journal of Zoology

Rising environmental stressors, including climate change, nutrient loading, pollution,  and anthropogenic impacts, have made the continuous monitoring of lake water  quality increasingly essential. While in situ methods offer high precision, satellite-based remote sensing is essential for capturing large-scale, long-term changes and  accessing remote or extreme environments. To complement these approaches, we  developed a cost-effective in situ optical measurement system specifically designed  for optically complex inland waters. T he instrument enables detailed optical  characterization across scattering angles from 0° to 160° and wavelengths between  423 and 728 nm, covering both visible and near-infrared regions. Initial validation was  performed using monocultures of …

Assessing Tree Species Diversity In Forests Using Combined Remote Sensing Data, Tufan Demi̇rel

Turkish Journal of Agriculture and Forestry

Tree species diversity (TSD) is a critical biological variable for ecosystem functioning and sustainable forest management.This study aimed to model TSD in forest ecosystems using spectral and texture metrics extracted from Sentinel-2, WorldView-3,and PlanetScope satellite imagery, and structural metrics derived from LiDAR data. Tree species data collected through field surveyswere used to calculate Shannon, Simpson, and species richness biodiversity indices. These biodiversity indicators were then related toexplanatory variables derived from remote sensing (RS) metrics. The Boruta algorithm was applied for variable selection and randomforest regression analysis was used for modeling. The results show that combining LiDAR and satellite data is …

Production Of The Antitumor Compound Deoxyharringtonine By Suspension-Culturedcells Of Cephalotaxus Hainanensis, Liang Wang, Muhammad Mubashar Zafar, Chongyu Wu, Zhiqiang Xiong, Jingyi Sun, Huapeng Sun, Hanqing Cong, Xuefei Jiang, Mahmoud F. Seleiman, Fei Qiao, Peter Nick

Turkish Journal of Agriculture and Forestry

Plant cell fermentation can be a sustainable biotechnological alternative to the wild collection of medicinal plants. As aparadigm, we explored the potential of using the highly endangered endemic tree Cephalotaxus hainanensis, which accumulatescephalotaxine esters—potent anticancer compounds. We successfully established a suspension cell line able to convert cephalotaxineinto its esters, including deoxyharringtonine, harringtonine, isoharringtonine and homoharringtonine at a remarkable maximalconversion rate of up to 86%, when supplemented with L-homoleucine, a precursor for the side chains of these esters. Furthermore, byadding elicitors, we were able to enhance the yield significantly beyond the values expected from the complete conversion of the addedcephalotaxine. In …

Rapid Single-Cell Measurement Of Transient Transmembrane Water Flow Under Osmotic Gradient, Hong Jiang, Jinnawat Jongkhumkrong, Y. J. Chao, Qian Wang, Guiren Wang

Faculty Publications

Aquaporins (AQPs) are critical for transmembrane water transport in response to osmotic gradients, but their gating and regulatory mechanisms remain poorly understood. A central challenge is the lack of methods to measure water flow across AQPs from individual cells with the spatiotemporal resolution and sensitivity equivalent to patch-clamp recordings of ion fluxes—a limitation stemming from the electrically silent nature of water flow. Here, we present a novel optical technique—Flow-Induced Fluorescence Increase Velocimetry (FIFIV) based on Laser-Induced Fluorescence Photobleaching Anemometry (LIFPA)—that enables direct, real-time monitoring of cytoplasmic flow induced by transmembrane water transport under osmotic pressure gradients. Using small molecular fluorescent …

Turning Zwitterions Into Toughening Agents: Salt-Activated Microdomains In Poly(Vinyl Alcohol) Double-Network Hydrogels, Louis D. Zhang, Jintao Yang, Si Yu Zheng

University Research

Zwitterionic hydrogels, although highly biocompatible, are widely regarded as mechanically fragile, with typical tensile strengths below 0.1 MPa, which restricts their use in load-bearing applications. Here, we address this limitation by integrating a polyzwitterionic network with a poly(vinyl alcohol) (PVA) network through high-speed pregelation agitation that enhances chain entanglement and induces flow orientation. By exploiting the salt-driven conformational transition of zwitterionic chains, a controlled salting-out step generates uniformly dispersed nanoscale microdomains that act as reversible energy-dissipating units. At the same time, balanced hydrogen bonding between the two networks moderates PVA crystallinity, limiting embrittlement while preserving elasticity. The resulting double-network hydrogel …

Ant Queens Divide Tasks Among Themselves To Maximize Efficiency In Multi-Queen Colonies, Ian Brush

Research on Capitol Hill

Before workers arrive, founding queens must sustain the colony on their own. In single-queen colonies, one queen performs all necessary tasks. In contrast, when several queens co-found a colony, their contributions often differ: some queens invest more in egg-laying, while others devote more effort to brood care or nest maintenance.

HIV infection remains a major global health challenge due to its complex pathogenesis and lifelong persistence in people living with HIV (PLWH). A central barrier to eradication is the virus's ability to establish long-lived latent reservoirs in different tissues, including the central nervous system (CNS), where it evades immune clearance and antiretroviral therapy (ART). These reservoirs, seeded early during infection, fuel viral rebound if ART is interrupted, requiring lifelong treatment. In the CNS, HIV persists despite systemic viral suppression because of limited ART penetration across the blood-brain barrier (BBB), and infection of long-lived cells such as microglia and perivascular macrophages. …

Gendered Harms In Armed Conflict: International Legal Responses To The Gendered Effects Of The War In Sudan, Naima Dams

Theses and Dissertations

This thesis interrogates how international law conceptualizes, prosecutes, and ultimately limits the understanding of sexual violence in contexts of war and displacement. Drawing on feminist legal theory, postcolonial critique, and ethnographic fieldwork with Sudanese women displaced in Egypt, it questions the dominant legal framing of conflict-related sexual violence (CRSV) as episodic, exceptional, and individualized. Instead, it reveals sexual violence as structural, continuous, and embedded in the everyday realities of racialized, gendered, and colonial harm.

Through ethnographical narratives, the study exposes how survivors' experiences often exceed the legibility frameworks of humanitarian and legal institutions, which prioritize spectacular, forensic evidence over slow, …

Medical-Surgical Nurses’ Perceptions On Incivility In A Hospital Setting, Monsurat Atinuke Mohammed

Walden Dissertations and Doctoral Studies

Incivility in nursing has become a chronic issue that harms nurses, patients, teams, and organizations. Individuals often feel belittled, which contributes to frequent job dissatisfaction and resignation, ultimately resulting in financial losses for an organization. The purpose of this qualitative descriptive study, guided by Johnson’s behavioral model, was to explore nurses’ perceptions about incivility in a medical-surgical hospital setting. Ten semistructured audio-recorded interviews were conducted with registered nurses recruited through a professional organization. The data were manually transcribed verbatim and analyzed using Saldana’s approach. Results indicated four themes: (a) workplace culture and interpersonal dynamics, (b) need for support and mentorship, …

Coordinated Stimulation Of Axon Regenerative And Neurodegenerative Transcriptional Programs By Atf4 Following Optic Nerve Injury, Preethi Somasundaram, Madeline M Farley, Melissa A Rudy, Katya Sigal, Andoni I Asencor, David G Stefanoff, Malay Shah, Puneetha Goli, Jenny Heo, Shufang Wang, Nicholas M Tran, Trent A Watkins

Stress signaling is important for determining the fates of neurons following axonal insults. Previously, we showed that the stress-responsive kinase PERK contributes to injury-induced neurodegeneration (Larhammar et al., 2017). Here, we show that PERK acts primarily through activating transcription factor-4 (ATF4) to stimulate not only pro-apoptotic but also pro-regenerative responses following optic nerve damage. Using conditional knockout mice, we find an extensive PERK/ATF4-dependent transcriptional response that includes canonical ATF4 target genes and modest contributions by C/EBP Homologous Protein (CHOP). Overlap with c-Jun-dependent transcription suggests interplay with a parallel stress pathway that orchestrates regenerative and apoptotic responses. Accordingly, neuronal knockout of …

Merritt-Putnam Symposium | Tumor-Associated Epilepsy And Epilepsy-Associated Tumors: Exploring The Bidirectional Crosstalk Between Tumors And Seizures, Tracy A Bedrosian, Michael Wong, Erin L Heinzen, Benjamin Deneen, Catherine A Christian-Hinman

Faculty, Staff and Students Publications

Links between cancerous and noncancerous brain tumors and epilepsy have long been recognized. However, recent clinical and preclinical studies emphasize that not only do tumors impinge on surrounding brain tissue in ways that promote hyperexcitability and epileptogenesis, but that neural activity also influences tumor progression. In this review, inspired by the Merritt-Putnam Symposium of the 2025 meeting of the American Epilepsy Society, we present a cross-disciplinary dialog between cancer and epilepsy research, including discussion of tumors and epilepsies that are more prominent in pediatric versus adult populations. First, we discuss the neuropathology, genetics, and surgical outcomes of epileptogenic brain tumors, …

Faculty, Staff and Student Publications

Systemic inflammation ("inflammaging") accelerates biological aging and drives cardiovascular, metabolic, and neurodegenerative disease. Circadian rhythms regulate the amplitude and timing of immune responses, yet their mechanistic role in inflammation and longevity remains unexplored. In 62,000 adults with 7-day wearable accelerometry, interpretable machine learning model identified rhythm amplitude, stability, and moderate-to-vigorous physical activity (MVPA) as dominant predictors of accelerated aging. In a subset of 1521 participants (35% male) with available data on the systemic immune-inflammation index (SII), we further examined the associations between behavioral rhythmicity and inflammation. Low amplitude and poor rhythm stability were associated with 0.31 and 0.18 SD higher …
