Coronin1A regulates the trafficking of alpha synuclein in microglia.

Microglia respond to cytotoxic protein aggregates associated with the progression of neurodegenerative disease. Pathological protein aggregates activate the microglial NLRP3 inflammasome resulting in proinflammatory signaling, secretion, and potentially pyroptotic cell death. We characterized mixed sex primary mouse microglia exposed to microbial stressors and alpha synuclein preformed fibrils (αsyn PFFs) to identify cellular mechanisms related to Parkinson's disease.

Non-invasive electron paramagnetic resonance imaging detects tumor redox imbalance induced by ferroptosis.

Targeting ferroptosis, cell death caused by the iron-dependent accumulation of lipid peroxides, and disruption of the redox balance are promising strategies in cancer therapy owing to the physiological characteristics of cancer cells. However, the detection of ferroptosis using imaging remains challenging. We previously reported that redox maps showing the reduction power per unit time of implanted tumor tissues via non-invasive redox imaging using a novel, compact, and portable electron paramagnetic resonance imaging (EPRI) device could be compared with tumor tissue sections.

Nanopore-based random genomic sampling for intraoperative molecular diagnosis.

Background: Central nervous system tumors are among the most lethal types of cancer. A critical factor for tailored neurosurgical resection strategies depends on specific tumor types. However, it is uncommon to have a preoperative tumor diagnosis, and intraoperative morphology-based diagnosis remains challenging.

Healthcare Resource Utilization in the Two Years Prior to Total Shoulder Arthroplasty.

Background: Reverse (RTSA) and anatomic total shoulder arthroplasty (ATSA) are the gold standard surgical treatments for symptomatic glenohumeral osteoarthritis (OA). Typically, these procedures are pursued after exhausting medical management and non-arthroplasty procedures. There is little reliable evidence focused on non-arthroplasty treatments for glenohumeral OA, although their use is widespread.

Composite spin probes with adjustable oxygen sensitivity for pulse electron paramagnetic resonance imaging.

Purpose: Solid crystalline spin probes, such as lithium phthalocyanine (LiPc) and lithium octa-n-butoxynaphthalocyanine (LiNc-BuO), allow repeated oxygen measurement using electron paramagnetic resonance (EPR). Due to their short relaxation times, their use for pulse EPR oxygen imaging is limited. In this study, we developed and tested a new class of solid composite spin probes that modified the relaxation rates R and R of LiPc or LiNc-BuO probes, which allowed pO measurements in the full dynamic (0-760 torr) range.

Integrative co-registration of elemental imaging and histopathology for enhanced spatial multimodal analysis of tissue sections through TRACE.

Summary: Elemental imaging provides detailed profiling of metal bioaccumulation, offering more precision than bulk analysis by targeting specific tissue areas. However, accurately identifying comparable tissue regions from elemental maps is challenging, requiring the integration of hematoxylin and eosin (H&E) slides for effective comparison. Facilitating the streamlined co-registration of whole slide images (WSI) and elemental maps, TRACE enhances the analysis of tissue regions and elemental abundance in various pathological conditions.

Polymeric Anti-Antibiotic Microparticles to Prevent Antibiotic Resistance Evolution.

Vancomycin (VAN) and daptomycin (DAP) are among the last-resort antibiotics for treating multidrug-resistant Gram-positive bacterial infections. They are administered intravenously (IV); however, ≈5 - 10% of the total IV dose is released in the gastrointestinal (GI) tract via biliary excretion, driving resistance emergence in commensal Enterococcus faecium (E. faecium) populations.

Introduction/objectives: Patients returning to the community from incarceration (ie, reentry) are at heightened risk of experiencing trauma when interacting with the healthcare system. Healthcare professionals may not recognize patients' trauma reactions or know how to effectively respond. This paper describes the development and pilot evaluation of a single-session training to prepare primary care teams to deliver trauma-informed care (TIC) to patients experiencing reentry.

Novel Neurocognitive Testing Tool for Early Neurotoxicity Detection Following Anti-CD19 and Anti-BCMA Chimeric Antigen Receptor (CAR) T-cell Therapy: A Pilot Study.

Background: Immune effector cell-associated neurotoxicity syndrome (ICANS) can be a severe, life-threatening toxicity following CAR T-cell therapy. While currently evaluated by the immune effector cell-associated encephalopathy (ICE) score, not all patients have changes in their ICE score and not all signs and symptoms of neurotoxicity are captured.

Methods: We conducted a prospective, single center cohort pilot study to evaluate a novel, rapid neurocognitive assessment tool (CART-NS) in detecting early, subtle neurotoxicity prior to the onset of ICANS and any deterioration in the ICE score.

Predictive equation derived from 6,497 doubly labelled water measurements enables the detection of erroneous self-reported energy intake.

Nutritional epidemiology aims to link dietary exposures to chronic disease, but the instruments for evaluating dietary intake are inaccurate. One way to identify unreliable data and the sources of errors is to compare estimated intakes with the total energy expenditure (TEE). In this study, we used the International Atomic Energy Agency Doubly Labeled Water Database to derive a predictive equation for TEE using 6,497 measures of TEE in individuals aged 4 to 96 years.

Enhancing representation of special populations: An approach to the inclusion of women veterans in VA clinical trials.

The under-recruitment of historically marginalized populations into clinical trials thwarts equitable inclusion of individuals who could benefit from healthcare innovations and limits the generalizability of results. For decades, the Veterans Health Administration (VA) has conducted large clinical trials that impact clinical guidelines for veterans and civilians alike. Within the VA, women are a numeric minority, and recruitment of this population into trials is challenged by gender-specific care structures, distinct demographic characteristics, and mistreatment such as higher rates of military sexual trauma and harassment on VA grounds.
