Unilateral Online Ultrasound Stimulation Of Early Visual Cortex Suppresses Responses To Contralateral Visual Stimuli, Suraya Dunsford, Keith Murphy, Ema Darrieutort, Elsa Fouragnan, Giorgio Ganis

School of Psychology

INTRODUCTION: Transcranial ultrasound stimulation (TUS) shows great promise for inducing neuroplastic changes that persist long after stimulation. Evidence of stimulation-locked (online) neural changes would enable the development of closed-loop application of TUS. However, such responses have been difficult to distinguish from coincident neural activity caused by auditory and somatosensory effects of TUS.

METHODS: To dissociate genuine online neuromodulatory effects from peripheral confounds, we leveraged the contralateral retinotopic organization of the early visual cortex in nineteen subjects. Using a hemifield visual stimulation paradigm combined with high-precision, functional MRI-guided TUS, we applied TUS to the left early visual cortex while participants viewed …

From Damage Signals To Immune Modulators: Oxidized Lipids In Immunometabolic Inflammation, Neetu Srivastava, Xiaoxiao Wan

2020-Current year OA Pubs

Oxidized lipids, once viewed as byproducts of oxidative stress, are now recognized as critical mediators linking metabolism, redox imbalance, and immunity. Generated through enzymatic and nonenzymatic oxidation of polyunsaturated fatty acids, oxidized phospholipids, lipid aldehydes, and oxidized lipoproteins act as context-dependent signals regulating immune activation, resolution, and metabolic adaptation. In metabolic inflammation, these lipids engage scavenger and Toll-like receptors to influence macrophage polarization, dendritic-cell function, and T-cell differentiation. Their context and concentration determine whether oxidized lipids amplify inflammation or promote immune tolerance. Accumulation of these species connects oxidative stress to immune dysfunction, contributing to diseases, such as atherosclerosis, obesity, diabetes, …

Impulsivity In Cerebellar Ataxia: An Online, Multidimensional Assessment, Brooke Chasalow, Yakov Flaumenhaft, Yael De Picciotto, Chi-Ying R Lin, Leila Montaser-Kouhsari, William Saban

Faculty, Staff and Students Publications

While considered a motor control structure, the cerebellum contributes to non-motor functions, including impulsivity. However, whether it contributes to impulsivity in a domain-specific manner remains unknown. Studies on cerebellar ataxia (CA), a common model for cerebellar dysfunction, typically have small sample sizes, limiting robustness. In a multicenter cross-sectional study, we investigated the cerebellum's role in various forms of impulsivity by comparing large cohorts of CA to age- and education-matched neurotypical healthy (NH) controls. Additionally, to examine the ability to identify individuals with CA using impulsivity features alone, we developed supervised machine learning (ML) models. In experiment 1 (CA = 140, …

The Soviet Template And Its Application: Bulgarian State Policy Toward The Bulgarian Orthodox Church After 1944, Ventzislav Gueorgiev Karavaltchev

Occasional Papers on Religion in Eastern Europe

The article examines the adoption and implementation of Soviet models in Bulgarian state policy toward the Bulgarian Orthodox Church following the communist takeover on September 9, 1944. Situating the Bulgarian case within a broader comparative framework, the study traces key continuities between Soviet church–state relations after the October Revolution of 1917—particularly as was institutionalized during the Stalinist period—and their subsequent application in Bulgaria. Drawing on extensive archival materials from Bulgarian and Russian repositories, the article demonstrates that all major decisions concerning the Church were closely coordinated with, and often directly approved by, Moscow. Beyond repression and legal restriction, the analysis …

Hegemonial Nationalism And The Role Of Religion: A View From The Perspective Of The Western Balkans, Semir Halilović, Tomislav Tadic

Occasional Papers on Religion in Eastern Europe

This paper points to the problem of hegemonic nationalism, with an emphasis on the role of religion, in the context of a social understanding of the situation in the Western Balkans (Bosnia and Herzegovina, Serbia, Montenegro, and Croatia). The question of the “Eastern and Western models of nationalism” is articulated, and the social role of religion in their construction is examined. In relation to this framework, the possibilities for applying the thesis of the Eastern model of the nation are considered in light of the current war situation between Russia and Ukraine. The paper highlights some of the theoretical configurations …

Polygyny Between Sharia, Custom And State Law As A Persistent Dilemma In Post-Soviet Kyrgyzstan, Zharkynbai Sebetov, Mairambek Tagaev

Occasional Papers on Religion in Eastern Europe

This article presents a comprehensive study of the century-long historical and legal evolution of state-imposed prohibitions on the institution of polygyny in Kyrgyzstan. The primary objective of the research is to evaluate the outcomes of a hundred years of repressive policies – originally classified as “crimes of daily life” (bytovye prestupleniya) during the early Soviet era–and to uncover the transformed legal paradoxes of this phenomenon today. Drawing on historical archival materials, Communist Party reports, and contemporary regulatory acts, the authors investigate the fundamental reasons why polygyny persists as a resilient “shadow” institution in Kyrgyz society despite its criminalization. Within the …

Countering Wahhabism And Promoting Religious Stability In Kazakhstan: Theological Insights From Qawam Ad-Din Al-Itqani, Rizabek Battaluly, Shamshadin Kerim, Nurlan Anarbayev, Ershat Vice-Rector Ongar

Occasional Papers on Religion in Eastern Europe

Following Kazakhstan’s independence, the expansion of religious freedoms created a societal religious vacuum, which, coupled with the low level of religious literacy among youth, facilitated the spread of radical ideologies. Historical evidence indicates that Wahhabism entered the region through broader Salafi movements, doctrinally grounded in the teachings of Ibn Taymiyya, contributing notably to inter-religious tensions among younger generations. Traditional Islamic frameworks in Central Asia – the Hanafi school of jurisprudence and the Maturidi creed – have historically played a central role in maintaining religious stability. The scholarly works of Qawam ad-Din al-Itqani, a prominent intellectual from the Turkistan region, systematically …

Prior Head Circumference Measurements In Infants With Older Subdural Hematomas: Did We Miss It?, Maryann Alvarez Griffis, Nancy D. Kellogg, Wouter Koek

School of Medicine Publications

Objective: To establish whether infants with macrocephaly and non-acute subdural hematomas (SDHs) had missed opportunities for measuring fronto-occipital circumference (FOC) and obtaining neuroimaging prior to diagnosis. Macrocephaly due to SDH in infancy is initially detected by FOC measurements and/or neuroimaging, as neurologic symptoms may be subtle or missed.

Methods: Retrospective chart review of infants with macrocephaly and non-acute SDHs referred to child abuse pediatricians for suspected abusive head trauma (AHT) over an 8-year period. A study sample of 35 infants met inclusion criteria and had complete prior medical records which were reviewed for missed opportunities for earlier SDH diagnosis. Four …

Impact Of Cyp2d6 Genotype And Inhibitor Use On Risperidone Metabolism In Children: Functional Insights Into The *17 And *29 Alleles, Matthew H. Bennett, Ethan A. Poweleit, Samuel E. Vaughn, Brandon Retke, Paul Toren, Jeffrey R. Strawn, Laura B. Ramsey

Student Publications

Risperidone, an atypical antipsychotic, is increasingly prescribed in pediatric patients with psychiatric disorders. It is primarily metabolized by CYP2D6 to 9-hydroxyrisperidone, an active metabolite associated with a higher risk of adverse effects. The CYP2D6*17 and *29 alleles are prevalent in individuals of African ancestry and less studied than variants found in European ancestry individuals. This knowledge gap contributes to differences in health outcomes in individuals of non-European origin. The primary objective of this study is to replicate recently identified risperidone-specific activity for the CYP2D6*17 and *29 alleles. During psychiatric hospitalization, CYP2D6 was genotyped as part of routine care. Remnant plasma …

Policy Considerations For Universal Congenital Cytomegalovirus Screening In Colorado: Insights From Minnesota’S Model, Elizabeth Wood

Doctoral Scholarly Projects & Capstones

Congenital cytomegalovirus (cCMV) is the most common congenital infection in developed countries and a leading non-genetic cause of sensorineural hearing loss (SNHL) and neurodevelopmental impairment in children. Despite its significant public health impact, newborn screening policies for cCMV remain inconsistent across the United States. Recent policy developments, including Minnesota’s implementation of universal newborn cCMV screening (2023) and Colorado’s adoption of an expanded-targeted screening approach (2025), have intensified discussion regarding optimal strategies for early detection and intervention. This narrative review synthesizes current evidence on the epidemiology, clinical manifestations, diagnostic methods, treatment options, and long-term outcomes of cCMV, with a particular focus …

Rab GTPases are key regulators of endosomal trafficking in eukaryotes. In mammalian cells, Rab4 and Rab7 were shown to localize to distinct compartments, with Rab4 on early endosomes for fast recycling and Rab7 on late endosomes for degradation. Here, we show that in Drosophila, endogenous Rab4 and Rab7 extensively colocalize across tissues and developmental stages. Recruited to the same compartments through mechanisms that do not require the activity of the other, they have opposing effects on endolysosomal size: Rab4 overexpression or Rab7 impairment leads to enlarged endolysosomes, whereas Rab4 loss or constitutively active Rab7 reduces their sizes. Rab4 deficiency suppresses …

Simulation-Free Spine Palliative Radiotherapy Enabled By Ai-Adapted Diagnostic Ct, Yiding Han, Alexander Nicola Hanania, Zaid Ali Siddiqui, Vincent Ugarte, Boran Zhou, Abdallah S R Mohamed, Piyush Pathak, Daniel Allen Hamstra, Baozhou Sun

Faculty, Staff and Students Publications

Background: Radiotherapy planning traditionally requires a dedicated simulation CT (sCT), which can introduce delays in initiating treatment. This is particularly impactful in spinal palliative care, where timely treatment is often important for symptom control and prevention of neurological deterioration. Although diagnostic CT (dCT) is frequently available earlier in the workflow, it can lead to geometric and dosimetric inaccuracies when used directly for treatment planning due to discrepancies in patient positioning, vertebral alignment, and table curvature.

Purpose: To develop and evaluate an AI-based method that transforms dCT into a simulation-equivalent planning CT (AI-pCT), enabling a clinically feasible simulation-free workflow for spinal …

Oral Ferrous Sulphate Supplementation Has Greater Efficacy, But Lower Tolerance Than Iron (Iii)-Hydroxide Polymaltose Complexes In Exercising Women With Low Iron Stores, Alannah Ka Mckay, Sophie Broome, Nicolin Tee, Kin Lui Yim, Marc Sim, Peter Peeling, Louise M. Burke

Research outputs 2022 to 2026

Background & Aims: Iron deficiency (ID) is a global health condition that predominately affects women. Although oral iron supplementation is an effective treatment strategy for this issue, gastrointestinal complaints are common, and if persistent, may lead to poor compliance. The efficacy of different iron formulations which claim to improve tolerance is unclear. This study assessed the efficacy and tolerability of ferrous sulphate (FS) and iron (III)-hydroxide polymaltose complex (IPC) supplementation in three different cohorts of women.. Methods: This study implemented a 12-week, single-blind, randomized controlled trial. Eligible participants had a serum ferritin concentration of <50 μg/L and met specific inclusion criteria to be enrolled to either the athlete, pre-menopausal or post-menopausal groups. Participants were randomized to receive FS (equivalent to 105 mg elemental iron) plus sodium ascorbate or IPC (equivalent to 100 mg elemental iron) daily. Venous blood samples were collected at baseline, 4-, 8- and 12-weeks of supplementation. A daily questionnaire was completed throughout the study period, documenting supplement tolerance (number and severity of symptoms), exercise load, menstrual characteristics, and supplement compliance. Results: Fifty-seven participants completed the intervention with a compliance rate of 94.9 % [range: 74.8-100 %]. A significant interaction between supplement and time was evident for ferritin (p < 0.001), where FS increased after 12 weeks (+109 %; p < 0.001) but no change was evident in IPC (+7 %; p = 0.727). No differences were detected between cohorts (p > 0.05). The IPC group had a …
