Changes In Reproductive Health Information-Seeking Behaviors After The Dobbs Decision: Systematic Search Of The Wikimedia Database, Mackenzie Lemieux, Cyrus Zhou, Caroline Cary, Jeannie Kelly

2020-Current year OA Pubs

BACKGROUND: After the US Supreme Court overturned Roe v. Wade, confusion followed regarding the legality of abortion in different states across the country. Recent studies found increased Google searches for abortion-related terms in restricted states after the Dobbsv. Jackson Women's Health Organization decision was leaked. As patients and providers use Wikipedia (Wikimedia Foundation) as a predominant medical information source, we hypothesized that changes in reproductive health information-seeking behavior could be better understood by examining Wikipedia article traffic.

OBJECTIVE: This study aimed to examine trends in Wikipedia usage for abortion and contraception information before and after the Dobbs decision.

Antibody radionuclide conjugates are an emerging modality for targeted imaging and potent therapy of disseminated disease. Coupling of radionuclides to monoclonal antibodies (mAbs) is typically achieved by applying non-site-specific labelling techniques. With the ambition of reducing variability, increasing labelling efficacy and stability, several site-specific conjugation strategies have been developed in recent years for toxin- and fluorophore-mAb conjugates. In this study, we studied two site-specific labelling strategies for the conjugation of the macrocyclic chelating agent, DOTA, to the anti-Leucine Rich Repeat Containing 15 (LRRC15) mAb DUNP19. Specifically, one approach utilized a DOTA-bearing peptide (FcIII) with a strong affinity for the fragment …

The blood-brain barrier (BBB) controls the movement of molecules into and out of the central nervous system (CNS). Since a functional BBB forms by mouse embryonic day E15.5, we reasoned that gene cohorts expressed in CNS endothelial cells (EC) at E13.5 contribute to BBB formation. In contrast, adult gene signatures reflect BBB maintenance mechanisms. Supporting this hypothesis, transcriptomic analysis revealed distinct cohorts of EC genes involved in BBB formation and maintenance. Here, we demonstrate that epigenetic regulator's histone deacetylase 2 (HDAC2) and polycomb repressive complex 2 (PRC2) control EC gene expression for BBB development and prevent Wnt/β-catenin (Wnt) target genes …

Chemotherapy is often combined with immune checkpoint inhibitor (ICI) to enhance immunotherapy responses. Despite the approval of chemo-immunotherapy in multiple human cancers, many immunologically cold tumors remain unresponsive. The mechanisms determining the immunogenicity of chemotherapy are elusive. Here, we identify the ER stress sensor IRE1α as a critical checkpoint that restricts the immunostimulatory effects of taxane-chemotherapy and prevents the innate immune recognition of immunologically cold triple-negative breast cancer (TNBC). IRE1α RNase silences taxane-induced dsRNA through RIDD (Regulated IRE1-Dependent Decay) to prevent NLRP3 inflammasome–dependent pyroptosis. Inhibition of IRE1α in Trp53−/− TNBC allows taxane to induce extensive dsRNAs that are sensed …

The continued emergence of SARS-CoV-2 variants and the threat of future Sarbecovirus zoonoses have spurred the design of vaccines that can induce broad immunity against multiple coronaviruses. Here, we use computational methods to infer ancestral phylogenetic reconstructions of receptor binding domain (RBD) sequences across multiple Sarbecovirus clades and incorporate them into a multivalent adenoviral-vectored vaccine. Mice immunized with this pan-Sarbecovirus vaccine are protected in the upper and lower respiratory tracts against infection by historical and contemporary SARS-CoV-2 variants, SARS-CoV, and pre-emergent SHC014 and Pangolin/GD coronavirus strains. Using genetic and immunological approaches, we demonstrate that vaccine-induced protection unexpectedly is conferred principally …

Childhood exposure to social disadvantage is a major risk factor for psychiatric disorders and poor developmental, educational, and occupational outcomes, presumably because adverse exposures alter the neurodevelopmental processes that contribute to risk trajectories. Yet, given the limited social mobility in the United States and other countries, childhood social disadvantage is frequently preceded by maternal social disadvantage during pregnancy, potentially altering fetal brain development during a period of high neuroplasticity through hormonal, microbiome, epigenetic, and immune factors that cross the placenta and fetal blood-brain barrier. The current study examines prenatal social disadvantage to determine whether these exposures in utero are associated …

Wearable Surface Electromyography System To Predict Freeze Of Gait In Parkinson's Disease Patients., Anna Moore, Jinxing Li, Christopher H Contag, Luke J Currano, Connor O Pyles, David A Hinkle, Vivek Shinde Patil

Neuroscience Articles

Freezing of gait (FOG) is a disabling yet poorly understood paroxysmal gait disorder affecting the vast majority of patients with Parkinson's disease (PD) as they reach advanced stages of the disorder. Falling is one of the most disabling consequences of a FOG episode; it often results in injury and a future fear of falling, leading to diminished social engagement, a reduction in general fitness, loss of independence, and degradation of overall quality of life. Currently, there is no robust or reliable treatment against FOG in PD. In the absence of reliable and effective treatment for Parkinson's disease, alleviating the consequences …

Domain-Specific Representation Of Social Inference By Neurons In The Human Amygdala And Hippocampus, Runnan Cao, Julien Dubois, Adam N Mamelak, Ralph Adolphs, Shuo Wang, Ueli Rutishauser

2020-Current year OA Pubs

Inferring the intentions and emotions of others from behavior is crucial for social cognition. While neuroimaging studies have identified brain regions involved in social inference, it remains unknown whether performing social inference is an abstract computation that generalizes across different stimulus categories or is specific to certain stimulus domain. We recorded single-neuron activity from the medial temporal lobe (MTL) and the medial frontal cortex (MFC) in neurosurgical patients performing different types of inferences from images of faces, hands, and natural scenes. Our findings indicate distinct neuron populations in both regions encoding inference type for social (faces, hands) and nonsocial (scenes) …

Four main medulloblastoma (MB) molecular subtypes have been identified based on transcriptional, DNA methylation, and genetic profiles. However, it is currently not known whether 3D genome architecture differs between MB subtypes. To address this question, we performed in situ Hi-C to reconstruct the 3D genome architecture of MB subtypes. In total, we generated Hi-C and matching transcriptome data for 28 surgical specimens and Hi-C data for one patient-derived xenograft. The average resolution of the Hi-C maps was 6,833 bp. Using these data, we found that insulation scores of topologically associating domains (TADs) were effective at distinguishing MB molecular subgroups. TAD …

Differential Relationship Between Meditation Methods And Psychotic-Like And Mystical Experiences, Timothy Palmer, Kenza Kadri, Eric Fakra, Jacqueline Scholl, Elsa Fouragnan

School of Psychology

Much work has investigated beneficial effects of mindfulness-based meditation methods, but less work has investigated potential risks and differences across meditation methods. We addressed this in a large pre-registered online survey including 613 mediators where we correlated participants' experience with fifty meditation techniques to psychotic-like experiences (PLEs) and mystical experiences. We found a positive correlation for both PLEs and mystical experiences with techniques aiming at reducing phenomenological content ('null-directed', NDM) or classified as non-dual or less embodied. In contrast, methods aiming at achieving an enhanced cognitive state (CDM), also described as 'attentional' or strongly embodied, showed negative correlations with PLEs. …

A Review Of The Association Between Dietary Intake And Brain Iron Levels In Older Adults: Preliminary Findings And Future Directions., Valentinos Zachariou, Christopher E. Bauer, Colleen A. Pappas, Brian T. Gold

Behavioral Science Faculty Publications

Background/Objectives: Non-heme iron is essential for critical neuronal functions such as ATP generation, synaptogenesis, neurotransmitter synthesis, and myelin formation. However, as non-heme iron accumulates with age, excessive levels can contribute to oxidative stress, potentially disrupting neuronal integrity and contributing to cognitive decline. Despite growing evidence linking high brain iron with poorer cognitive performance, there are currently no proven methods to reduce brain iron accumulation in aging or to protect cognitive function from iron’s negative effects. Recent studies suggest that nutrition may influence brain iron levels, though the evidence remains limited and mixed. Methods: In this review, we explore recent findings, …
