Peri-implant soft tissue conditioning of immediate posterior implants by CAD-CAM socket sealing abutments: a randomized clinical trial

open access: yesBMC Oral Health
Background Anatomically formed healing abutments were suggested in literature to address many of the issues associated with immediate posterior implant insertion such as large extraction sockets that are extremely hard to seal without reflecting the ...

Advanced Age in Sinus Surgery: Diminished Symptom Gains but Enhanced Surgical Durability in Chronic Rhinosinusitis

open access: yesOtolaryngology–Head and Neck Surgery, EarlyView.
Abstract Objective To assess whether patients of advanced age with chronic rhinosinusitis (CRS) experience comparable symptom improvement and disease control following endoscopic sinus surgery (ESS) compared to younger patients. Data Sources Systematic searches were performed across PubMed, Embase, Web of Science, Scopus, and CENTRAL to May 2024 ...

Facile Separation of Gadolinium(III) from Samarium(III) and Lanthanum(III) by Emulsion Liquid Membrane and the Optimization with the Box‐Behnken Design Method

open access: yesChemistryOpen, EarlyView.
Facile separation of Gd(III) from Sm(III) and La(III) is achieved using an emulsion liquid membrane with tributyl phosphate as extractant. Optimization by Box‐Behnken design reveals critical parameter interactions, enabling improved selectivity and efficiency, highlighting the potential of this approach for rare earth element purification.

Succinate Promotes M1 Polarization of Intestinal Macrophages in Mice With Necrotizing Enterocolitis Through the PI3K/AKT Pathway

open access: yesPediatric Discovery, EarlyView.
Succinate promotes macrophage to the M1 phenotype in the mouse mononuclear macrophage leukemia cells (Raw264.7 cells) and neonatal mice with NEC. Succinate activates the phosphatidylinositol 3‐kinase/protein kinase B (PI3K/AKT) pathway via succinate recepter 1 (SUCNR1), promoting M1 polarization of NEC intestinal macrophages.

Location‐Assisted Graph‐Based User Scheduling in Multi‐User MIMO LEO NTN Systems

open access: yesInternational Journal of Satellite Communications and Networking, EarlyView.
ABSTRACT This paper addresses user clustering and scheduling for multi‐user MIMO low Earth orbit nonterrestrial network systems in full frequency reuse. Since the number of on‐ground user terminals is usually much higher than the number of on‐board LEO satellite antennas, user scheduling becomes a fundamental task.

Multifunctional Polymer Matrix at the Buried Interface Boosting Stability and Efficiency in Perovskite Solar Cells

open access: yesSmall, EarlyView.
Sodium hyaluronate (SHA) serves as a polymer matrix that stabilizes the SnO2 dispersion and, by reconstructing the buried interface, holistically enhances both the overall performance and long‐term stability of perovskite solar cells. SHA promotes the regular arrangement of SnO2 during thin‐film formation and eliminates oxygen defects.
