Identification of senescence‐related genes in Parkinson's disease reveals candidate therapeutic targets and pathological processes

Animal Models and Experimental Medicine, EarlyView.
At the genomic level, a large number of differentially expressed genes (DEGs) and aging‐related DEGs have been screened. Ten hub genes, such as IFNγ and IRF7, have been identified and shown potential value in the diagnosis of PD, holding promise as novel biomarkers to facilitate early and precise diagnosis.

Study on the performance of basalt fiber geopolymer concrete by freeze-thaw cycle coupled with sulfate erosion

AIP Advances
In this research, double-blended materials such as fly ash and slag are used as binders, and basalt fibers (BF) are mixed in varying volume fractions (0.2%, 0.4%, 0.6%, 0.8%, and 1.0%) relative to the volume of concrete. Besides, sodium silicate (Na2SiO3)

Optimization of F¯ Removal From Wastewater Utilizing Alternating Current Electrocoagulation Coupled With Sonication Using a Statistical Design Approach

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Combining electrochemical and advanced oxidation processes (AOPs) has greatly mitigated the limitations of electrocoagulation (EC) in water treatment. This study examined the effectiveness of sonolysis (US)‐assisted alternating current (AC)–EC in reducing fluoride (F¯) from landfill leachate wastewater (LLW), with measurements of electrical ...

Synthesis of a Novel Amine‐Based Curing Agent for Epoxy Resins Derived From Vanillin

Journal of Applied Polymer Science, EarlyView.
The four‐step synthesis of a new bio‐based amine hardener is described starting from vanillin as a bio‐based compound. The hardener ADBA was utilized to cure DGEBA and the resulting Tg,tanδmax was determined via DMA. Compared to other bio‐based curing agents, our curing agent is obtainable in a high yield and leads to a superior Tg of 135°C.

Porous Poly(ε‐Caprolactone)/Keratin Composite Scaffolds: Structural Features, Degradation Behavior and Cell‐Material Interactions

Journal of Applied Polymer Science, EarlyView.
ABSTRACT Porous scaffolds based on pure poly(ε‐caprolactone) (PCL) and on biocomposite made of PCL and feather‐extracted β‐keratin (FK) were fabricated by salt‐leaching method. FK was incorporated into PCL to address the limited bioactivity and hydrophobic nature of PCL, with the aim of improving cell–material interactions for bone tissue engineering ...

SULFATE ATTACK RESISTANCE OF INTERNALLY CURED HIGH-PERFORMANCE CONCRETE CONTAINING MILLET HUSK ASH

Due to the difficulties in maintaining failing concrete structures built with normal concrete (NC), high-performance concrete (HPC), which is extremely dense and has a low water-binder content, has been developed. However, it has been observed that inadequate internal curing in HPC can lead to autogenous shrinkage and micro-cracking.

Anti‐Carbamylated Protein Antibodies Stabilize Carbamylated Histone H3 to Promote Synovial Activation and Neutrophil Extracellular Trap‐Mediated Bone Loss in Rheumatoid Arthritis

Arthritis &Rheumatology, EarlyView.
Objective Carbamylation, a nonenzymatic post‐translational modification, contributes to rheumatoid arthritis (RA) pathogenesis. Anti‐carbamylated protein antibodies (anti‐CarP) occur in around 50% of patients with RA and associate with greater joint damage. Neutrophil extracellular traps (NETs) are a major source of carbamylated autoantigens. We sought

Fine Particulate Matter Constituents, Ozone, and Systemic Lupus Erythematosus: A Large General‐Population Cohort Analysis With Extended Quantile g‐Computation

Arthritis &Rheumatology, EarlyView.
Objective The aim of this study was to investigate whether exposure to mixture of individual fine particulate matter (PM2.5) chemical constituents is associated with incident systemic lupus erythematosus (SLE) and if ozone modifies this association and/or is associated with SLE onset.
