CONCLUSIONS: We report an efficient method for producing faithful in vitro models of LGG. New experimental platforms generated through this approach are well positioned to support preclinical studies of this disease, particularly those related to tumor immunology, tumor-stroma interactions, identification of novel drug targets, and personalized assessments of treatment response profiles.

CONCLUSIONS: There appear to be no municipal-level racial/ethnic inequities in naloxone distribution in Rhode Island and Massachusetts, USA.

AB-506, a small-molecule inhibitor targeting the HBV core protein, inhibits viral replication in vitro (HepAD38 cells: EC(50) of 0.077 μM, CC(50) > 25 μM) and in vivo (HBV mouse model: ∼3.0 log(10) reductions in serum HBV DNA compared to the vehicle control). Binding of AB-506 to HBV core protein accelerates capsid assembly and inhibits HBV pgRNA encapsidation. Furthermore, AB-506 blocks cccDNA establishment in HBV-infected HepG2-hNTCP-C4 cells and primary human hepatocytes, leading to...

It has been suggested that the sequestration of CO(2) by agricultural soils offers a means to reduce atmospheric greenhouse gas (GHG) concentrations and in turn mitigate the impacts of climate change. Carbon sequestration by grassland soils, which account for more than 60% of agricultural land use in Ireland, could contribute to a successful net reduction of atmospheric GHG emissions in accordance with the COP21 Paris Agreement. However, current estimates of soil carbon sequestration are...

Cellular transport and function are dependent on substrate influx and efflux of various compounds. In humans, the largest superfamily of transporters is the SoLute Carriers (SLCs). Many transporters are orphans and little to nothing is known about their expression and/or function, yet they have been assigned to a cluster called atypical SLCs. One of these atypical SLCs is MFSD11. Here we present a first in-depth characterization of the MFSD11, CG18549. By gene expression and behavior analysis on...

OBJECTIVE: Laser interstitial thermal therapy (LITT) is a minimally invasive surgery for mesial temporal lobe epilepsy (mTLE), but the effects of individual patient anatomy and location of ablation volumes affect seizure outcomes. The purpose of this study is to see if features of individual patient structural connectomes predict surgical outcomes after LITT for mTLE.

Flight training programs incur great risks as they instruct aspiring pilots to complete flight training and licensing procedures. It is instrumental for these programs to create strong safety cultures and climates to promote the highest level of safety possible. The COVID-19 pandemic raised many safety concerns across a variety of industries, especially the aviation industry. This study investigates the impact that the COVID-19 pandemic had on the safety culture and safety climate of the flight...

Cardiac lymphoma is a rare neoplasm involving heart, pericardium or both, usually seen in immunocompromised patients. We report a 61-year-old male presenting with worsening shortness of breath and 20-pound weight loss. Investigations showed right-sided tumor with interatrial septal wall perforation and left atrial expansion. The diagnosis was confirmed with mediastinal mass biopsy. After receiving the appropriate treatment, there was a steady improvement clinically and on the transesophageal...

Introduction: Patients in the pediatric intensive care unit (PICU) are at risk of developing long-term morbidities following recovery from their critical illness. One such health outcome is called post-intensive care syndrome (PICS). PICS in pediatrics may be mitigated by interventions that facilitate adjustment to the PICU setting. Methods: The PICU implemented a two-pronged Peer and Volunteer (P/V) Program to help: (a) families adjust to the PICU experience with the support of a peer mentor...

CONCLUSIONS: Despite efforts to diversify the demographic constitution of incoming neurosurgical trainees, few significant advances have been made in recent years. This study suggests that improved strategies for recruitment and cultivating early interest in neurological surgery are required to further increase the diversification of future cohorts of neurosurgical trainees.

CONCLUSIONS: The COVID-19 pandemic acutely affected patient care and overall institutional operations. The research consortium of New York and New Jersey rehabilitation institutions responded dynamically to bed expansions/contractions, staff deployment, and innovations that facilitated safe and effective patient care.

CONCLUSION: There is significant variation in bariatric surgery utilization between states, with almost a 5-fold difference between the states with the highest and lowest utilization.

Previous genome-wide association studies revealed multiple common variants involved in eczema but the role of rare variants remains to be elucidated. Here, we investigate the role of rare variants in eczema susceptibility. We meta-analyze 21 study populations including 20,016 eczema cases and 380,433 controls. Rare variants are imputed with high accuracy using large population-based reference panels. We identify rare exonic variants in DUSP1, NOTCH4, and SLC9A4 to be associated with eczema. In...

CONCLUSIONS: In the largest contemporary MINOCA meta-analysis to date, patients with suspected MINOCA had a favorable prognosis compared with MI-CAD, but statistically nonsignificant trend toward worse outcomes compared to those with No-MI.

Vaccination to prevent infectious disease is one of the most successful public health interventions ever developed. And yet, variability in individual vaccine effectiveness suggests that a better mechanistic understanding of vaccine-induced immune responses could improve vaccine design and efficacy. We have previously shown that protective antibody levels could be elicited in a subset of recipients with only a single dose of the hepatitis B virus (HBV) vaccine and that a wide range of antibody...

High expression of LIN28B is associated with aggressive malignancy and poor survival. Here, probing MYCN-amplified neuroblastoma as a model system, we showed that LIN28B expression was associated with enhanced cell migration in vitro and invasive and metastatic behavior in murine xenografts. Sequence analysis of the polyribosome fraction of LIN28B-expressing neuroblastoma cells revealed let-7-independent enrichment of transcripts encoding components of the translational and ribosomal apparatus...

Despite improved knowledge regarding disease causality, new drug targets, and enabling technologies, the attrition rate for compounds entering clinical trials has remained consistently high for several decades, with an average 90% failure rate. These failures are manifested in an inability to reproduce efficacy findings from animal models in humans and/or the occurrence of unexpected safety issues, and reflect failures in T1 translation. Similarly, an inability to sequentially demonstrate...

This study aimed to assess the cytotoxicity of commercially available adhesive strategies-etch-and-rinse (Adper^(™) Scotchbond^(™) 1 XT, 3M ESPE, St. Paul, MN, USA, SB1), self-etch (Clearfil^(™) SE Bond 2, Kuraray Noritake Dental Inc., Tokyo, Japan, CSE), and universal (Scotchbond^(™) Universal, 3M Deutschland GmbH, Neuss, Germany, SBU). MDPC-23 cells were exposed to adhesives extracts in different concentrations and exposure times. To access cell metabolic activity, viability, types of cell...
