A Living Feminist Postdevelopmental Lexicon For Early Education, Mindy Blaise, Veronica Pacini-Ketchabaw

Research outputs 2022 to 2026

Expanding the important body of work that addresses child development’s limitations and responding to the ecological crisis that threatens the future of life on Earth, this article proposes a living feminist postdevelopmental lexicon. The lexicon introduces 26 concepts that together challenge the theory/practice divide, disrupt Cartesian modes of subjectivity, reorient taken-for-granted ideas as problematic in early education, open up early education to inquiries that respond to the political and ethical questions of our milieu, and generate conditions for creative, inventive, thoughtful, and ethical projects. The paper invites readers to engage with and creatively add to the lexicon, making it an …

Ags3-Based Optogenetic Gdi Induces Gpcr-Independent Gβγ Signalling And Macrophage Migration, Waruna Thotamune, Sithurandi Ubeysinghe, Chathuri Rajarathna, Dinesh Kankanamge, Koshala Olupothage, Aditya Chandu, Bryan A Copits, Ajith Karunarathne

G-protein-coupled receptors (GPCRs) are efficient guanine nucleotide exchange factors (GEFs) and exchange GDP to GTP on the Gα subunit of G-protein heterotrimers in response to various extracellular stimuli, including neurotransmitters and light. GPCRs primarily broadcast signals through activated G proteins, GαGTP and free Gβγ and are major disease drivers. Evidence shows that the ambient low threshold signalling required for cells is likely supplemented by signalling regulators such as non-GPCR GEFs and guanine nucleotide dissociation inhibitors (GDIs). Activators of G-protein signalling 3 (AGS3) are recognized as a GDI involved in multiple health and disease-related processes. Nevertheless, understanding of AGS3 is limited, …

Mitochondria are central to myriad biochemical processes, and thus even their moderate impairment could have drastic cellular consequences if not rectified. Here, to explore cellular strategies for surmounting mitochondrial stress, we conducted a series of chemical and genetic perturbations to Saccharomyces cerevisiae and analysed the cellular responses using deep multiomic mass spectrometry profiling. We discovered that mobilization of lipid droplet triacylglycerol stores was necessary for strains to mount a successful recovery response. In particular, acyl chains from these stores were liberated by triacylglycerol lipases and used to fuel biosynthesis of the quintessential mitochondrial membrane lipid cardiolipin to support new mitochondrial …

Endogenous And Fluorescent Sterols Reveal The Molecular Basis For Ligand Selectivity Of Human Sterol Transporters, Laura Depta, Hogan P Bryce-Rogers, Nienke J Dekker, Anna Wiehl Bønke, Nicolò Camporese, Mingxing Qian, Yuanjian Xu, Douglas F Covey, Luca Laraia

Sterol transport proteins (STPs) play a pivotal role in cholesterol homeostasis and therefore are essential for healthy human physiology. Despite recent advances in dissecting functions of STPs in the human cell, there is still a significant knowledge gap regarding their specific biological functions and a lack of suitable selective probes for their study. Here, we profile fluorescent steroid-based probes across ten STPs, uncovering substantial differences in their selectivity, aiding the retrospective and prospective interpretation of biological results generated with those probes. These results guided the establishment of an STP screening panel combining diverse biophysical assays, enabling the evaluation of 42 …

Using Integrin Αvβ6-Targeted Positron Emission Tomography Imaging To Longitudinally Monitor Radiation-Induced Pulmonary Fibrosis In Vivo, William C Y Lo, Cristian W Villas Boas, Truc T Huynh, Amanda Klaas, Felicia Grogan, Lori Strong, Pamela Samson, Clifford G Robinson, Buck E Rogers, Carmen Bergom

2020-Current year OA Pubs

PURPOSE: Radiation-induced pulmonary fibrosis (RIPF) is a potentially serious and disabling late complication of radiation therapy. Monitoring RIPF progression is challenging due to the absence of early detection tools and the difficulty in distinguishing RIPF from other lung diseases using standard imaging methods. In the lungs, integrin αvβ6 is crucial in the development of RIPF, acting as a significant activator of transforming growth factor β after radiation injury. This study aimed to investigate integrin α

METHODS AND MATERIALS: We used a focal RIPF model (70 Gy delivered focally to a 3 mm spot in the lung) and a whole lung …

OBJECTIVE: Rett syndrome (RTT) and MECP2 duplication syndrome (MDS) result from under- and overexpression of MECP2, respectively. Preclinical studies using genetic-based treatment showed robust phenotype recovery for both MDS and RTT. However, there is a risk of converting MDS to RTT, or vice versa, if accurate MeCP2 levels are not achieved. The aim of this study was to identify biomarkers distinguishing RTT from MDS.

MATERIALS AND METHODS: We prospectively enrolled 11 MDS and 6 male RTT like (MRL) individuals for a panel of clinical and neurophysiological assessments over two visits, 8-10 months apart.

RESULTS: We identified numerous clinical and physiological …

Virus-Specific T-Cell Therapy For The Management Of Viral Infections In The Immunocompromised, Kiriakos Koukoulias, Penelope Georgia Papayanni, Ann Marie Leen, Spyridoula Vasileiou

Faculty, Staff and Students Publications

Background: Immunocompromised individuals are at major risk for severe infectious complications. This is particularly relevant in the context of allogeneic hematopoietic stem cell transplantation (allo-HCT) - a treatment modality that has proven curative for a range of malignant and nonmalignant hematological diseases. However, transplant-associated immune suppression leaves patients susceptible to infectious complications from viruses such as cytomegalovirus (CMV), adenovirus (AdV), Epstein-Barr virus (EBV), and BK virus (BKV). While pharmacological agents are available to prevent and/or treat some of these viruses, they can be associated with significant toxicities and are often ineffective. To circumvent these issues, several groups have explored the …

Parkinson’s disease (PD) is an incurable, progressive and common movement disorder that is increasing in incidence globally because of population aging. We hypothesized that the landscape of rare, protein-altering variants could provide further insights into disease pathogenesis. Here we performed whole-exome sequencing followed by gene-based tests on 4,298 PD cases and 5,512 controls of Asian ancestry. We showed that GBA1 and SMPD1 were significantly associated with PD risk, with replication in a further 5,585 PD cases and 5,642 controls. We further refined variant classification using in vitro assays and showed that SMPD1 variants with reduced enzymatic activity display the strongest …

In 2018, after law enforcement announced it had used a technique called forensic investigative genetic genealogy (FIGG) to identify the Golden State Killer, we conducted a U.S. general population survey and found most respondents supported using FIGG to solve violent crimes. Since then, FIGG has helped close hundreds of criminal cases, but it also has weathered controversies. On FIGG's fifth anniversary, we conducted an expanded, follow-up survey with U.S.-based participants to determine if public opinion had changed and found continued support for FIGG across most applications. The same proportion (91 %) of respondents in the 2018 and 2023 surveys endorsed …

Incidence And Survival Of Children And Adolescents With Wilms Tumor, United States, 2001-2020, Andres F Espinoza, Ekene Onwuka, David A Siegel, Shifan Dai, Sanjeev A Vasudevan, Michael E Scheurer, Philip J Lupo

Center for Medical Ethics and Health Policy Staff Publications

Background: Wilms tumor (WT) is the most common pediatric malignancy of the kidney. Past studies describing WT incidence and survival used surveillance data with < 30% of the US population. We evaluated differences in WT incidence and survival comparing demographic groups and tumor characteristics.

Methods: We analyzed new cases of WT among patients aged < 20 years at diagnosis by using incidence data from US Cancer Statistics (USCS) for 2003-2020 and 5-year relative survival (RS) data from the National Program of Cancer Registries (NPCR) for 2001-2019. To assess incidence trends, average annual percent change (AAPC) was calculated by using joinpoint regression. Relative survival (RS) and all-cause survival were calculated overall and by demographic and clinical variables.

Results: During 2003-2020, 8218 cases of WT were reported in USCS, which represented an age-adjusted incidence rate of 5.7 cases per million. Rates were the highest among females (6.3), children aged 0-4 years (17.2), and non-Hispanic Black patients (7.1). Overall, trends remained stable (AAPC = -0.4, 95% CI: -1.4 to 0.4). Among 7567 cases of WT in NPCR, 5-year RS was 92.6%. Patients with the lowest …

Methods: Clinical variables and somatic mutation data for 20 genes from 641 patients with RMS in the United Kingdom and the United States were used to develop three Cox proportional hazard models for predicting event-free survival (EFS). The Baseline Clinical (BC) model included treatment location, age, fusion status, and risk group. The Gene Enhanced 2 (GE2) model added TP53 and MYOD1 mutations to the BC predictors. The Gene …

Revisiting What Constitutes A Neglected Tropical Disease?, Paul J Brindley, Peter J Hotez, Shaden Kamhawi

Center for Medical Ethics and Health Policy Staff Publications

PLOS Neglected Tropical Diseases (PLOS NTDs) publishes research devoted to pathogenesis and other clinical aspects, epidemiology, prevention, diagnosis, treatment, and control of the neglected tropical diseases (NTDs), as well as work relevant to public health policy. We define NTDs as poverty-promoting infectious diseases that can negatively impact the quality of life in rural areas and poor urban areas of low- and middle-income countries but which can also affect specific communities within high-income countries. The poverty-inducing effects of the NTDs operate by impairing child health and development, pregnancy outcomes for both mother and child, worker productivity, and quality of life. The …

Longitudinal Phage-Bacteria Dynamics In The Early Life Gut Microbiome, Michael J Tisza, Richard E Lloyd, Kristi Hoffman, Daniel P Smith, Marian Rewers, Sara J Javornik Cregeen, Joseph F Petrosino

Center for Medical Ethics and Health Policy Staff Publications

Microbial colonization of the human gut occurs soon after birth, proceeds through well-studied phases and is affected by lifestyle and other factors. Less is known about phage community dynamics during infant gut colonization due to small study sizes, an inability to leverage large databases and a lack of appropriate bioinformatics tools. Here we reanalysed whole microbial community shotgun sequencing data of 12,262 longitudinal samples from 887 children from four countries across four years of life as part of the The Environmental Determinants of Diabetes in the Young (TEDDY) study. We developed an extensive metagenome-assembled genome catalogue using the Marker-MAGu pipeline, …

The Cost Of Inflammatory Bowel Disease Care: How To Make It Sustainable, Johan Burisch, Jennifer Claytor, Inmaculada Hernandez, Jason Ken Hou, Gilaad G Kaplan

Faculty, Staff and Students Publications

The rising global prevalence of inflammatory bowel diseases (IBDs), such as Crohn's disease and ulcerative colitis, underscores the need to examine current and future IBD care costs. Direct health care expenses, including ambulatory visits, hospitalizations, and medications, are substantial, averaging $9,000 to $12,000 per person annually in high-income regions. However, these estimates do not fully account for factors such as disease severity, accessibility, and variability in health care infrastructure among regions. Indirect costs, predominantly stemming from loss in productivity due to absenteeism, presenteeism, and other intangible costs, further contribute to the financial burden of IBD. Despite efforts to quantify indirect …

Neurodegeneration is presumed to be the pathological process measure most proximal to clinical symptom onset in Alzheimer Disease (AD). Structural MRI is routinely collected in research and clinical trial settings. Several quantitative MRI-based measures of atrophy have been proposed, but their low correspondence with each other has been previously documented. The purpose of this study was to identify which commonly used structural MRI measure (hippocampal volume, cortical thickness in AD signature regions, or brain age gap [BAG]) had the best correspondence with the Clinical Dementia Rating (CDR) in an ethno-racially diverse sample. 2870 individuals recruited by the Healthy and Aging …

Watershed Land Use Decreases The Nitrogen Limitation Of Benthic Algal Growth In Coastal Wetlands Of A Large Oligotrophic Lake, Matthew J. Cooper, Michele C. Wheeler

Open Access Publishing Support Funded Articles

Introduction:

Identifying patterns in the primary limiting nutrients of basal trophic levels such as benthic algae can inform the prediction of potential ecological responses to anthropogenic nutrient loading. In coastal wetlands of the Laurentian Great Lakes, reduced concentrations of reactive nitrogen species such as ammonium and nitrate may limit algal growth, especially when nutrient loading is minimal. However, the response of benthic algae to macronutrient inputs remains understudied, especially in Lake Superior coastal wetlands.

Methods:

We conducted nutrient amendment assays using nutrient diffusing substrate devices in 25 coastal wetlands along the southwestern shore of Lake Superior in the spring, summer, …

The Role Of Childhood Stress In Inflammatory Skin Conditions: A Neuroimmune Investigation, Marissa Ruppe, Colin Burnette, Emily Deehan, Emily Woolhiser, Haily A. Fritts, Kelly Frasier, Aspynn Owsley, Savannah K. Fakhouri, Veronica Rodriguez

Student Publications

Emerging evidence indicates that childhood stressors, such as familial conflict, bullying, academic pressure, and traumatic events, can significantly worsen inflammatory skin conditions like atopic dermatitis (AD) and psoriasis. This review explores the underlying neuroimmune pathways that link stress to skin inflammation in children, focusing on the role of the hypothalamic-pituitary-adrenal (HPA) axis and stress-induced cytokine production. Studies have shown that chronic psychological stress leads to dysregulation of the HPA axis, resulting in elevated cortisol levels, which paradoxically impair skin barrier function and upregulate pro-inflammatory cytokines such as IL-6, TNF-α, and IL-1β. Specific stressors, such as bullying, have been associated with …

Following the project-based learning (PBL) framework, the course was extremely interactive, culminating in a project where students were asked to “materially improve health inequalities out in the real world.” The students responded by …

Recurrent Selection For Partial Resistance To Anthracnose Disease In Shrubby Stylo (Stylosanthes Scabra), D F. Cameron, R A. Boland, S Chakraborty, B Jamieson, J.A G. Irwin

IGC Proceedings (1977-2023)

Three cycles of crossing have been completed in a recurrent selection programme for partial resistance to anthracnose disease of shrubby stylo (Stylosanthes scabra) In a field study of a subset of 40 F2 populations from the first cycle, highly significant differences (P<0.001) in anthracnose resistance were found for both male and female effects and for the female x male interaction, In a subsequent F3 progeny test of 99 families selected for disease resistance and yield, 92 of the families were resistant to highly resistant with leaf damage <1% (cf, >50% damage for the susceptible cultivar, Fitzroy). Strong discrimination for resistance was also obtained in a second subset of 23 F2 populations using combined glasshouse and field selection for resistance. Further improvement in anthracnose resistance was achieved in the second and third cycles of recurrent selection. The broadly based resistance of selections from the third cycle …
