Development and characterization of in vitro inducible immortalization of a murine microglia cell line for high throughput studies.

There are few in vitro models available to study microglial physiology in a homeostatic context. Recent approaches include the human induced pluripotent stem cell model, but these can be challenging for large-scale assays and may lead to batch variability. To advance our understanding of microglial biology while enabling scalability for high-throughput assays, we developed an inducible immortalized murine microglial cell line using a tetracycline expression system.

Liquid-based encapsulation for implantable bioelectronics across broad pH environments.

Wearable and implantable bioelectronics that can interface for extended periods with highly mobile organs and tissues across a broad pH range would be useful for various applications in basic biomedical research and clinical medicine. The encapsulation of these systems, however, presents a major challenge, as such devices require superior barrier performance against water and ion penetration in challenging pH environments while also maintaining flexibility and stretchability to match the physical properties of the surrounding tissue. Current encapsulation materials are often limited to near-neutral pH conditions, restricting their application range.

Introduction: Non-adherence to tuberculosis (TB) treatment poses a significant challenge to effective TB management globally and is a major contributor to the emergence of multidrug-resistant TB. Although adherence to TB treatment has been widely studied, a comprehensive evaluation of the comparative levels of adherence in high- versus low-TB burden settings remains lacking. The objective of this systematic review and meta-analysis is to assess the levels of adherence to TB treatment in high-TB burden countries compared to low-burden countries.

A Multivariate Analysis of a Modified Frailty Index on Perioperative Morbidity and Mortality Following Non-Emergent Endovascular Aortic Aneurysm Repair.

Objective: Frailty has become an increasingly recognized perioperative risk stratification tool. While frailty has been strongly correlated with worsening surgical outcomes, the individual determinants of frailty have rarely been investigated in the setting of aortic disease. The aim of this study was to examine the determinants of an 11-factor modified frailty index (mFI-11) on mortality and postoperative complications in patients undergoing endovascular aortic aneurysm repair (EVAR).

Anatomic and Reverse Total Shoulder Arthroplasty for Osteoarthritis: Outcomes in Patients 80 Years Old and Older.

Background: There has been an increase in both primary anatomic (aTSA) and reverse total shoulder arthroplasty (rTSA) over the last decade, with rates peaking for patients aged 75 years and older. Despite aTSA being the mainstay of treatment for patients with glenohumeral arthritis in the absence of rotator cuff insufficiency, there has been an upward trend of rTSA utilization in the elderly due to concerns about rotator cuff integrity, regardless of deformity. The purpose of this study is to evaluate outcomes including pain, function, range of motion, satisfaction, and complications in patients 80 years or older following primary anatomic and reverse total shoulder arthroplasty for osteoarthritis without full thickness rotator cuff tears.

Racial and ethnic enrollment disparities in clinical trials leading to FDA approvals for gynecologic malignancies.

Background: Black women and other minorities have higher age adjusted incidence risk for cervical and endometrial cancer than White women. However, the extent of racial and ethnic disparities in clinical trial enrollment among studies performed mainly in North America and Europe for gynecologic malignancy is unknown.

Objective: This study analyzed enrollment rates by race/ethnicity in trials that led to Food and Drug Administration (FDA) approvals for gynecological cancers from 2010 to 2024.

Trends in Neurosurgeons Signing Medicare Opt-Out Affidavits.

Safety and efficacy of satralizumab in patients with generalised myasthenia gravis (LUMINESCE): a randomised, double-blind, multicentre, placebo-controlled phase 3 trial.

Background: Evidence from preclinical studies suggests that IL-6 signalling has the potential to modulate immunopathogenic mechanisms upstream of autoantibody effector mechanisms in patients with generalised myasthenia gravis. We aimed to assess the safety and efficacy of satralizumab, a humanised monoclonal antibody targeting the IL-6 receptor, in patients with generalised myasthenia gravis.

Methods: LUMINESCE was a randomised, double-blind, placebo-controlled, multicentre, phase 3 study at 105 sites, including hospitals and clinics, globally.

Safety and efficacy of nipocalimab in adults with generalised myasthenia gravis (Vivacity-MG3): a phase 3, randomised, double-blind, placebo-controlled study.

Background: Given burdensome side-effects and long latency for efficacy with conventional agents, there is a continued need for generalised myasthenia gravis treatments that are safe and provide consistently sustained, long-term disease control. Nipocalimab, a neonatal Fc receptor blocker, was associated with dose-dependent reductions in total IgG and anti-acetylcholine receptor (AChR) antibodies and clinically meaningful improvements in the Myasthenia Gravis Activities of Daily Living (MG-ADL) scale in patients with generalised myasthenia gravis in a phase 2 study. We aimed to assess the safety and efficacy of nipocalimab in a phase 3 study.

Real-time prediction of heparin concentration in blood extracorporeal circulation by relaxation time distribution (RTD).

Heparin concentration c in a blood extracorporeal circulation has been real-timely predicted based on the relaxation strength Δε at relaxation frequency f extracted by relaxation time distribution (RTD). The simulated extracorporeal circulation was conducted to optimize the number of Δε for the prediction of c using the porcine whole blood (WB) and low-leukocyte and -platelet blood (LLPB) under the condition of the gradual increment of c from 0 to 8 U/mL with constant flow rate and blood temperature. The experimental results show that among the three relaxation strengths Δε, Δε and Δε (in ascending order of frequency), Δε at f = 5.

Characterization of senescence-associated transcripts in the human placenta.

Introduction: Fusion of mononucleated cytotrophoblasts into syncytium leads to trophoblast senescence. Yet, premature senescence is associated with preeclampsia, fetal growth restriction (FGR), and related obstetrical syndromes. A set of 28 transcripts that comprise senescence-associated secretory phenotype (SASP) was recently described in placentas from women with preeclampsia.

Revisiting the electrophysiological correlates of valence and expectancy in reward processing - A multi-lab replication.

Two event-related brain potential (ERP) components, the frontocentral feedback-related negativity (FRN) and the posterior P300, are key in feedback processing. The FRN typically exhibits greater amplitude in response to negative and unexpected outcomes, whereas the P300 is generally more pronounced for positive outcomes. In an influential ERP study, Hajcak et al.
