Single-Cell Profiling Reveals Immune Aberrations in Progressive Idiopathic Pulmonary Fibrosis.

Changes in peripheral blood cell populations have been observed, but not detailed, at single-cell resolution in idiopathic pulmonary fibrosis (IPF). We sought to provide an atlas of the changes in the peripheral immune system in stable and progressive IPF. Peripheral blood mononuclear cells (PBMCs) from patients with IPF and control subjects were profiled using 10× chromium 5' single-cell RNA sequencing.

Insular cortex subregions have distinct roles in cued heroin seeking after extinction learning and prolonged withdrawal in rats.

Evidence indicates that the anterior (aIC), but not posterior (pIC), insular cortex promotes cued reinstatement of cocaine seeking after extinction in rats. It is unknown whether these subregions also regulate heroin seeking and whether such involvement depends on prior extinction learning. To address these questions, we used baclofen and muscimol (BM) to inactivate the aIC or pIC bilaterally during a seeking test after extinction or prolonged withdrawal from heroin.

Prescribed psychotropic medication patterns among treated Foster Care enrollees: a single institution study.

Background: While several state-based studies have shown that children in foster care are more likely to be prescribed psychotropic medications and experience concomitant medication use both within and among medication class, these patterns have not been explored in the state of Nevada, which lacks state mandated oversight of psychotropic prescribing for foster care enrolled youth.

Methods: Data from an electronic medical record system from a single institution were analyzed to examine the prevalence of psychotropic prescribing and concomitant medication use in children ages 2 to 19 who were enrolled and received psychotropic prescriptions between July 2019 to June 2022.

Results: Out of 569 distinct psychotropic medication treatment episodes within this cohort, the most frequent psychotropic classes prescribed were non-stimulant ADHD medications (alpha-agonists and atomoxetine, 31.

Clinical and biological relevance of glial fibrillary acidic protein in Alzheimer's disease.

Introduction: There is a tremendous need for identifying reliable blood-based biomarkers for Alzheimer's disease (AD) that are tied to the biological ATN (amyloid, tau and neurodegeneration) framework as well as clinical assessment and progression.

Methods: One hundred forty-four elderly participants underwent 18F-AV45 positron emission tomography (PET) scan, structural magnetic resonance imaging (MRI) scan, and blood sample collection. The composite standardized uptake value ratio (SUVR) was derived from 18F-AV45 PET to assess brain amyloid burden, and the hippocampal volume was determined from structural MRI scans.
