Article Abstract
This study, from the perspective of resource utilization and carbon sequestration, developed a novel lightweight carbonated solidified slurry material using reactive magnesium oxide (MgO), ground granulated blast furnace slag (GGBS), and carbide slag as stabilizers, with carbonation induced by a CO foaming method. The physical and mechanical properties of the material were investigated. Based on the optimal mix proportion, the effects of MgO content, CO foam dosage, and stabilizer dosage on wet density, flowability, moisture content, and unconfined compressive strength were analyzed. The results indicate that wet density increases with increasing MgO and stabilizer content but decreases with increasing CO foam dosage. Flowability decreases with increasing MgO and stabilizer content but improves with a higher CO foam dosage. Unconfined compressive strength increases with curing age and stabilizer content but decreases with increasing CO foam dosage. Additionally, prolonged curing enhances both moisture content and unconfined compressive strength. These findings provide a theoretical basis for engineering applications.

This study develops a novel geopolymer foamed concrete using coal gangue and slag as precursors, along with a composite alkali activator comprising sodium silicate and sodium hydroxide, based on the physical foaming method. The Box-Behnken Design within Response Surface Methodology was applied to optimize the mix proportions of coal gangue-slag-based geopolymer foamed concrete. The effects of alkali activator dosage, sodium silicate modulus, water-to-binder ratio, and foam content on 28-day compressive strength and thermal conductivity were systematically investigated to determine the optimal mix for achieving a balance between mechanical and thermal performance.

This study highlights the potential of nanoparticle-encapsulated colchicine as a safer and more effective alternative to free colchicine for treating atherosclerotic vascular disease (ASCVD). While colchicine is known for its anti-inflammatory properties, its dose-dependent toxicity limits long-term clinical use. To address this issue, colchicine was encapsulated in polymeric nanoparticles synthesized through a microfluidic method using methylated β-cyclodextrin as the initiator.

Elastomeric foam is an essential component in many industrial and technological settings, primarily as thermal insulators and as positional/mechanical support cushions. In particular, silicone foam is utilized in harsh environments due to exceptional thermal and chemical stability. Under service conditions within certain applications such material gets exposed to a high dosage of gamma radiation, which can permanently alter the material's structural and mechanical response properties.

Methods: In this prospective, open-label, single-center study, adults (≥18 years of age) with psoriasis (physician global assessment [PGA] ≥3, body surface area [BSA] ≥10%, and psoriasis area severity index [PASI] ≥12) took deucravacitinib (6 mg daily) for 8 weeks. At week 8, patients who achieved PASI 75 continued on deucravacitinib alone up to week 24; PASI 25-74 used daily, C/BD for 4 weeks; and <PASI 25 were discontinued.

Cardiovascular diseases are leading causes of death globally, often manifesting after years of atherosclerosis (AS) progression. In this study, we investigated the atheroprotective effects of three different sources of glucomannan, polysaccharide, glucomannan, and polysaccharide (AVP), using an ox-LDL-induced foam cell model and an high-fat high-cholesterol diet-fed ApoE mouse model. Both settings indicate that AVP exerts the most significant atheroprotective effects.
