Multi-Physical Lattice Metamaterials Enabled by Additive Manufacturing: Design Principles, Interaction Mechanisms, and Multifunctional Applications.

Lattice metamaterials emerge as advanced architected materials with superior physical properties and significant potential for lightweight applications. Recent developments in additive manufacturing (AM) techniques facilitate the manufacturing of lattice metamaterials with intricate microarchitectures and promote their applications in multi-physical scenarios. Previous reviews on lattice metamaterials have largely focused on a specific/single physical field, with limited discussion on their multi-physical properties, interaction mechanisms, and multifunctional applications.

Analysis of Depression in Aged, Hospitalized Patients with Chronic Heart Failure.

Objective: The objective is to investigate the situation and risk factors of depression in aged, hospitalized patients with chronic heart failure (CHF).

Methods: A total of 196 aged CHF patients admitted to Xuanwu Hospital from May 2022 to March 2024 were consecutively selected. Information such as demographics, comorbidities, old-age hospitalization assessment results, and admission test results was collected.

Inhibiting Friction-Induced Exogenous Adhesion via Robust Lubricative Core-Shell Nanofibers for High-Quality Tendon Repair.

Friction is the trigger cause for excessive exogenous adhesion, leading to the poor self-repair of the tendon. To address this problem, we developed electrospun dual-functional nanofibers with surface robust superlubricated performance and bioactive agent delivery to regulate healing balance by reducing exogenous adhesion and promoting endogenous healing. Coaxial electrospinning and our previous developed in situ robust nanocoating growth techniques were employed to create the lubricative/repairable core-shell structured nanofibrous membrane (L/R-NM).

An expanding universe of mutational signatures and its rapid evolution in single-stranded RNA viruses.

The study of mutational processes in somatic genomes has gained recent momentum, uncovering a wide array of endogenous and exogenous factors associated with somatic changes. However, the overall landscape of mutational processes in germline mutations across the tree of life and associated evolutionary driving forces are rather unclear. In this study, we analyzed mutational processes in single-stranded RNA (ssRNA) viruses which are known to jump between different hosts with divergent exogenous environments.

Efficacy and safety of acupuncture with moxibustion for knee osteoarthritis: a meta-analysis of randomized controlled trials.

Background: Osteoarthritis (OA) is prevalent, yet its management remains challenging. This meta-analysis aims to evaluate the efficacy of acupuncture combined with moxibustion versus other standard treatments in patients with knee osteoarthritis (KOA) based on randomized controlled trials (RCTs).

Methods: Searches were conducted in Ovid MEDLINE, Embase, and the Cochrane Central Register of Controlled Trials to retrieve relevant RCTs.
