Lessons from the National institutes of health innovation corps program: defining barriers to developing and commercializing novel solutions for persons with opioid use disorder.

Background: Translating innovative research advancements into commercially viable medical interventions presents well-known challenges. However, there is limited understanding of how specific patient, clinical, social, and legal complexities have further complicated and delayed the development of new and effective interventions for Opioid Use Disorder (OUD). We present the following case studies to provide introductory clinical, social, and business insights for researchers, medical professionals, and entrepreneurs who are considering or are currently developing medical.

Novel environment exposure drives temporally defined and region-specific chromatin accessibility and gene expression changes in the hippocampus.

The interaction of mammals with a novel environment (NE) results in structural and functional changes in multiple brain areas, including the hippocampus. This experience-dependent circuit reorganization is driven in part by changes in gene expression however, the dynamic sensory experience-driven chromatin states and the diverse cell type specific gene expression programs that are regulated by novel experiences are not well described. We employed single- nucleus multiomics (snRNA- and ATAC-seq) and bulk RNA-seq of the hippocampal DG, CA3, and CA1 regions to characterize the temporal evolution of cell-type-specific chromatin accessibility and gene expression changes that occur in 14 different cell types of the hippocampus upon exposure of mice to a novel environment.

Structural basis for the midnolin-proteasome pathway and its role in suppressing myeloma.

The midnolin-proteasome pathway degrades many nuclear proteins without ubiquitination, but how it operates mechanistically remains unclear. Here, we present structures of the midnolin-proteasome complex, revealing how established proteasomal components are repurposed to enable a unique form of proteolysis. While the proteasomal subunit PSMD2/Rpn1 binds to ubiquitinated or ubiquitin-like proteins, we discover that it also interacts with the midnolin nuclear localization sequence, elucidating how midnolin's activity is confined to the nucleus.

Inositol Phosphates and Synthesizing Enzymes: Implications in Neurodegenerative Disorders.

Inositol is a vital sugar molecule involved in numerous signaling pathways required for cellular homeostasis and cell survival. Myo-inositol and its phospho-derivatives, inositol phosphates (IPs), are the most prevalent forms of inositol found in living cells. They are involved in regulating ion channels, metabolic flux, stress response, and other key biological processes.

Admission Neutrophil-to-Lymphocyte Ratio Is Superior to WBC Count at Predicting the Presence and Severity of Pediatric Musculoskeletal Infection.

Background: Accurately determining the presence and severity of pediatric musculoskeletal infection (MSKI) is crucial for effective triage and treatment. Although the white blood-cell (WBC) count is often used as a marker for MSKI, we hypothesized that the use of the WBC count is limited by age-related variability in children. We proposed that the absolute neutrophil-to-lymphocyte ratio (NLR), which has less age-related variability, is a more reliable indicator for both diagnosing and assessing the severity of MSKI.
