Paternal Effects Without Paternity? Testing Non-Genetic Male Influence On Offspring Size And Brood Size In A Gynogenetic Vertebrate, The Amazon Molly (Poecilia Formosa), Ulrike Scherer, Sean Ehlman, David Bierbach, Jens Krause, Max Wolf

Faculty Publications

Paternal effects, i.e., effects of fathers on the phenotype of their offspring that are not mediated by the transmission of alleles, are increasingly recognized as a potentially significant source of phenotypic variation across taxa – even in the absence of paternal care. Gynogenetic systems, which rely on sperm to trigger embryogenesis without incorporating male genetic material, provide a powerful way to experimentally isolate paternal effects from effects caused by the integration of male genetic material. Up to now, however, paternal effects remain largely unexplored in these systems. Here, we tested for non-genetic paternal effects in the gynogenetic Amazon molly ( …

Epithelial ovarian cancer (EOC) is a leading cause of gynecological cancer mortality and is often diagnosed at an advanced stage, resulting in poor survival outcomes. Access to specialized gynecological oncology services has been associated with improved prognosis; however, data on its impact in Indonesia remain limited. This study aimed to evaluate the association between gynecologic oncologist (GO) services and disease-free survival (DFS) in patients with EOC. This retrospective cohort study included 76 patients with EOC who were treated at a national cancer hospital in Jakarta between 2015 and 2018. Patient data were obtained from medical records and followed for three …


Rewiring The Senses: Neural And Perceptual Adaptation Through Cultural Immersion In Chile, Alexa Castillo Feb 2026

Rewiring The Senses: Neural And Perceptual Adaptation Through Cultural Immersion In Chile, Alexa Castillo

University Honors Theses

This thesis explores how cultural immersion reshapes perception over time. Rather than focusing only on language acquisition, the project examines how sustained exposure to a new cultural and linguistic environment alters sensory processing, cognitive effort, and emotional experience. The study draws on cultural neuroscience and neuroplasticity research to frame immersion as a process of adaptive recalibration.

Over four weeks in Valparaíso, Chile, I documented daily changes in auditory processing, visual attention, emotional response, and social interpretation. Journal entries were analyzed using qualitative thematic coding and organized into five categories: language overload, cognitive effort, automaticity, anxiety/frustration, and belonging/comfort. Weekly intensity ratings …

Nanoscale Opportunities In Extracellular Matrix Mimicry, L. Andrew Lyon, Abbygail Caine, Elif Narbay, E. Daniel Cárdenas-Vásquez

Engineering Faculty Articles and Research

We present an overview of the composition, function, energetics, and dynamics of extracellular matrix and its relation to nanoscale structures and phenomena. These concepts are then related to the development of synthetic and biosynthetic materials that aim to mimic the extracellular matrix for regenerative medicine and tissue engineering technologies. Notable successes and advancements towards the goal of biomimicry are outlined, while remaining challenges and knowledge gaps towards that goal are highlighted. Finally, we frame the remaining challenges in the field in terms of nanoscience-related research opportunities that if solved, might prove to be transformative steps forward in the discipline.

Faculty, Staff and Student Publications

The bone marrow endosteum provides a robust source of bone-making osteoblasts by housing various types of osteoblast precursor cells, including endosteal stem cells expressing fibroblast growth factor receptor 3 (Fgfr3) and their downstream progenitor cell populations. In fetal bone development, Dlx5 marks early perichondrial cells that populate the diaphyseal bone and marrow stroma in the postnatal stages. However, the location of Dlx5-expressing cells in the postnatal bone marrow and how they contribute to osteogenesis remain undefined. Here, we show that Dlx5

Background: Dual mitogen-activated protein kinase (MAPK) pathway and autophagy inhibition shows synergistic antitumor activity in preclinical models of RAS-mutant cancers. We hypothesized that autophagy blockade with hydroxychloroquine (HCQ) could overcome resistance to MEK inhibition with binimetinib (BINI) and provide clinical benefit in previously treated, KRAS-mutated, metastatic pancreatic ductal adenocarcinoma (PDAC).

Methods: This investigator-led, single-arm, open-label, phase I dose escalation/expansion trial evaluated the safety and tolerability of BINI + HCQ in patients with previously treated, metastatic PDAC (NCT04132505). Key eligibility criteria: ECOG 0-1, adequate organ function, ≥ 1 prior line of therapy for metastatic disease, and presence of KRAS …


Concurrent Regimes For The Concept Of “Common Heritage” In Seabed Mining, James Kraska, Digvijay Rewatkar Feb 2026

Concurrent Regimes For The Concept Of “Common Heritage” In Seabed Mining, James Kraska, Digvijay Rewatkar

International Law Studies

This article examines the re-emergence of unilateral deep seabed mining by the United States and its implications for the concept of the common heritage of mankind. Triggered by Executive Order 14285 and the resurrection of the Deep Seabed Hard Mineral Resources Act, the U.S. approach challenges the multilateral framework established under Part XI of the United Nations Convention on the Law of the Sea (UNCLOS) and the 1994 Implementing Agreement. While the prevailing view holds that unilateral seabed mining is prohibited by customary international law and that only the International Seabed Authority (ISA) may lawfully operationalize the common heritage principle, …

Faculty, Staff and Student Publications

Endosteal stem cells are a subclass of bone marrow skeletal stem cell populations that are particularly important for rapid bone formation occurring in growth and regeneration. These stem cells are strategically located near the bone surface in a specialized microenvironment of the endosteal niche. These stem cells are abundant in young stages but eventually depleted and replaced by other stem cell types residing in a non-endosteal perisinusoidal niche. Single-cell molecular profiling and in vivo cell lineage analyses play key roles in discovering endosteal stem cells. Importantly, endosteal stem cells can transform into bone tumor-making cells when deleterious mutations occur in …

Early detection of dementia remains a pressing challenge in clinical neuroscience, as delayed diagnosis limits therapeutic impact and healthcare planning. Leveraging the Open Access Series of Imaging Studies (OASIS) cross-sectional dataset of 436 participants, this study developed a robust machine learning pipeline integrating sociodemographic, clinical, and neuroimaging-derived features. Preprocessing included removal of highly sparse variables (Delay), median imputation of partially missing but clinically essential measures (SES, MMSE, CDR, Educ), Winsorization of extreme values, and skewness correction. The target Clinical Dementia Rating (CDR) was binarized (0 = no dementia, ≥ 0.5 = dementia) to align with clinically actionable screening. Categorical features …


An Ai-Enhanced Ant Colony Optimization Based Routing Protocol, Niranjan M M, Srihari P Bhavanasi Feb 2026

An Ai-Enhanced Ant Colony Optimization Based Routing Protocol, Niranjan M M, Srihari P Bhavanasi

Defensive Publications Series

Proposed herein are techniques to address limitations in classical Ant Colony Optimization (ACO) routing protocols that rely on static, hand-crafted probabilistic rules and lack contextual awareness. Traditional ACO-based routing reacts slowly to rapid topology changes or fluctuating link quality, and pheromone evaporation alone cannot ensure fast convergence in highly dynamic or congested environments. To overcome these limitations, techniques herein replace conventional control packets with intelligent software-based AI agents that employ learning-based decision models. These AI agents evaluate link quality, predict route reliability, and optimize exploration behavior in real time by integrating machine-learning-based decision-making with adaptive ACO behavior. The techniques enable …

PS is highly susceptible to UV-induced photodegradation, which results in deterioration of its mechanical and aesthetic properties. In the present study, four novel and highly aromatic levofloxacin metal complexes, synthesized from Zn, Sn, Cu, and Ni, were investigated as low-concentration (0.5% w/w) photostabilizer additives for PS. Composite films were prepared by solution casting and subjected to accelerated UV irradiation up to 300 hours. Photostabilizing performance was systematically followed by monitoring changes in the carbonyl index via FT-IR spectroscopy, mass loss measurements, and surface morphology analyses using SEM and AFM. Results showed that all levofloxacin metal complexes had a pronounced inhibition …

Computational Repurposing And Experimental Validation Of Ybx1 Inhibitors In Hepatocellular Carcinoma, Omar Karkoutly, Veerababu Nagati, Subhash Chauhan, Manish Tripathi

School of Medicine Publications

Background/Objectives: Hepatocellular carcinoma (HCC) is the most common type of liver cancer worldwide. While early-stage HCC can often be treated with surgical resection, ablation, or liver transplantation, advanced disease typically relies on systemic chemotherapy. Sorafenib is the standard first-line therapy for advanced and unresectable HCC; however, both intrinsic and acquired resistance remain major clinical challenges. The Y-box binding protein-1 (YBX1), a transcription factor implicated in drug resistance across multiple cancers, is highly expressed in HCC and represents a potential therapeutic target. This study aimed to identify novel YBX1 inhibitors using a drug repurposing strategy to overcome sorafenib resistance. Methods: A …

Functional Characteristics Of Ice Creams Enriched With Aronia Melanocarpa And Sambucus Nigra L. Extracts, Murat Emre Terzi̇oğlu, Emi̇ne Maci̇t

Turkish Journal of Agriculture and Forestry

In this study, the effects of Aronia melanocarpa and Sambucus nigra L. extracts added at different concentrations (0.5%, 1%,and 1.5%) on the physicochemical, sensory, microbiological, antioxidant capacity (DPPH• and ABTS•+ radical scavenging activity, TPC,TFC, and TAC) antidiabetic (α-amylase and α-glucosidase inhibition), and anti-Alzheimer properties (AChE inhibitory activity) of icecream were investigated. According to the statistical analysis results, extract addition did not have an effect on the total dry matter, fatand ash ratios of the ice cream samples (p > 0.05), but it had an effect on the protein ratio, viscosity, and first drip time at the level ofp < 0.05. The addition of extract positively affected the DPPH• radical scavenging activity IC50 and ABTS•+ radical scavenging activityIC50 values of the ice cream samples, and also increased the TPC, TFC, and TAC values. Indeed, a decrease in the IC50 values of DPPH•and ABTS•+ radical scavenging activities indicates an increase in antioxidant activity. The highest TPC, TFC, and TAC values weredetected in the A-1.5 sample (sample containing 1.5% A. melanocarpa extract) as 749.33 mg GA/kg, 434.70 mg QE/kg, and 290.97 mg/kg, respectively. Similarly, the highest α-amylase inhibitory activity (23.08%), the highest α-glucosidase inhibitory activity (10.41%) andthe highest AChE inhibitory activity (14.70%) were observed in the A-1.5 sample. Extract addition had no effect on microbiologicalproperties and sensory properties except texture. The results of this study showed that A. melanocarpa, S. nigra L. extracts can be usedas a natural additive with antioxidant, antidiabetic and anti-Alzheimer activities in ice cream production.
