In human adults, visual perception varies throughout the visual field. Performance decreases with eccentricity and varies around polar angle. At isoeccentric locations, performance is typically higher along the horizontal than vertical meridian (horizontal-vertical asymmetry [HVA]) and along the lower than the upper vertical meridian (vertical meridian asymmetry [VMA]).

Single-cell RNA sequencing (scRNA-seq) is invaluable for profiling cellular heterogeneity and transcriptional states, but transcriptomic profiles do not always delineate subsets defined by surface proteins. Cellular indexing of transcriptomes and epitopes (CITE-seq) enables simultaneous profiling of single-cell transcriptomes and surface proteomes; however, accurate cell-type annotation requires a classifier that integrates multimodal data. Here, we describe multimodal classifier hierarchy (MMoCHi), a marker-based approach for accurate cell-type classification across multiple single-cell modalities that does not rely on reference atlases.

Electronic address:

Timed dopamine signals underlie reinforcement learning, favoring neural activity patterns that drive behaviors with positive outcomes. In the striatum, dopamine activates five dopamine receptors (D1R-D5R), which are differentially expressed in striatal neurons. However, the role of specific dopamine receptors in reinforcement is poorly understood.

Ischemic stroke and vascular cognitive impairment, caused by a sudden arterial occlusion or more subtle but protracted vascular insufficiency, respectively, are leading causes of morbidity and mortality worldwide with limited therapeutic options. Innate and adaptive immunity have long been implicated in neurovascular injury, but recent advances in methodology and new experimental approaches have shed new light on their contributions. A previously unappreciated dynamic interplay of brain-resident, meningeal, and systemic immune cells with the ischemic brain and its vasculature has emerged, and new insights into the frequent overlap between vascular and Alzheimer pathology have been provided.

Introduction: Racial disparities in prostate cancer (PC) are well studied among Black or African American (BAA) patients but not among Hispanics, a quickly growing US minority group. This study compared overall survival (OS) and healthcare resource utilization (HRU) by race in Medicaid-insured patients with metastatic castration-sensitive PC (mCSPC) and metastatic castration-resistant PC (mCRPC).

Materials And Methods: A retrospective longitudinal cohort study of Medicaid claims was conducted to estimate racial disparities in OS (with a multivariable Cox proportional hazards model) and in HRU (with a multivariable Poisson model), adjusting for confounding by demographic and clinical characteristics.

Using the Key Characteristics Framework to Unlock the Mysteries of Aryl Hydrocarbon Receptor-Mediated Effects on the Immune System.

Annu Rev Immunol

January 2025

3Department of Environmental Medicine and Department of Microbiology and Immunology, University of Rochester, Rochester, New York, USA; email:

Initially discovered for its role mediating the deleterious effects of environmental contaminants, the aryl hydrocarbon receptor (AHR) is now known to be a crucial regulator of the immune system. The expanding list of AHR ligands includes synthetic and naturally derived molecules spanning pollutants, phytochemicals, pharmaceuticals, and substances derived from amino acids and microorganisms. The consequences of engaging AHR vary, depending on factors such as the AHR ligand, cell type, immune challenge, developmental state, dose, and timing of exposure relative to the immune stimulus.

A mixed phenotype is characteristic of de novo Mixed Phenotype Acute Leukemia (MPAL) but can also be seen in other leukemias. It poses substantial classification and management dilemmas. Herein, we report a large cohort of acute leukemia with a mixed phenotype and define Acute Myeloid Leukemia with Mixed Phenotype (AML-MP) and MPAL as two distinct groups by characterizing the clinical, genetic, and transcriptomic features.

Apolipoprotein E (APOE) has multiple functions in metabolism and immunoregulation. Its common germline variants APOE2, APOE3 and APOE4 give rise to three functionally distinct gene products. Previous studies reported yin-yang roles of APOE2 and APOE4 in immunological processes, but their effects in hematopoietic stem cell transplantation (HSCT) have never been studied.

Background: Heart failure (HF) is one of the most common causes of hospital readmission in the United States. These hospitalizations are often driven by insufficient self-care. Commercial mobile health (mHealth) technologies, such as consumer-grade apps and wearable devices, offer opportunities for improving HF self-care, but their efficacy remains largely underexplored.

Objectives: To analyze sex differences in outcomes in Tourette syndrome (TS) and Persistent Motor or Vocal tic disorders (PMVT) in the Tourette Association of America International Consortium for Genetics (TAAICG) dataset.

Methods: The relationship between sex and clinical measures was explored in 2,403 participants (N = 2,109 with TS; N = 294 with PMVT) from the TAAICG dataset using generalized estimating equation regression models, and adjusted for age and family relationships.

Results: Female (vs male) participants with TS (25.

Background: An accurate knowledge of a patient's risk of cord-level intraoperative neuromonitoring (IONM) data loss is important for an informed decision-making process prior to deformity correction, but no prediction tool currently exists.

Methods: A total of 1,106 patients with spinal deformity and 205 perioperative variables were included. A stepwise machine-learning (ML) approach using random forest (RF) analysis and multivariable logistic regression was performed.

Giant cell tumors (GCTs) are benign but locally aggressive bone neoplasms that primarily affect skeletally mature individuals. They are characterized by a tendency for recurrence and being associated with significant morbidity. Traditional treatment has focused on surgical resection; however, the role of medical therapies, such as Denosumab, a bone anti-resorptive drug, which has been Food and Drug Administration (FDA)-approved for unresectable GCTs since 2013, recently has gained prominence.

ThCTi@(6)-C: Th═C Double Bond in a Mixed Actinide-Transition Metal Cluster.

College of Chemistry, Chemical Engineering and Materials Science, and State Key Laboratory of Radiation Medicine and Protection, Soochow University, Suzhou, Jiangsu 215123, P. R. China.

A thorium-carbon double bond that corresponds to the sum of theoretical covalent double bond radii has long been sought after in the study of actinide-ligand multiple bonding as a synthetic target. However, the stabilization of this chemical bond remains a great challenge to date, in part because of a relatively poor energetic matching between 5f-/6d- orbitals of thorium and the 2s-/2p- frontier orbitals of carbon. Herein, we report the successful synthesis of a thorium-carbon double bond in a carbon-bridged actinide-transition metal cluster, i.

» Patients with diabetes mellitus (DM) undergoing shoulder arthroplasty (SA) have a unique risk profile, which must be considered by clinicians.» The presence of DM as a comorbidity is associated with longer length of stay following SA, greater likelihood of nonhome discharge, and a higher rate of 90-day readmission.» Though the incidence is low, patients with DM are at an increased risk of serious postoperative cardiovascular complications, such as pulmonary embolism, venous thromboembolism, and myocardial infarction.

Genomic imprinting is an epigenetic process that results in parent-of-origin effects on mammalian development and growth. Research on genomic imprinting in domesticated animals has lagged due to a primary focus on orthologs of mouse and human imprinted genes. This emphasis has limited the discovery of imprinted genes specific to livestock.

Although we have a good understanding of how phenotypic plasticity evolves in response to abiotic environments, we know comparatively less about responses to biotic interactions. We experimentally tested how competition and mutualism affected trait and plasticity evolution of pairwise communities of genetically modified brewer's yeast. We quantified evolutionary changes in growth rate, resource use efficiency (RUE), and their plasticity in strains evolving alone, with a competitor, and with a mutualist.
