Association between urinary volatile organic compounds metabolites and rheumatoid arthritis among the adults from NHANES 2011-2018.

Rheumatoid arthritis (RA) is closely associated with environmental factors. Volatile organic compounds (VOCs) are a common environment pollutant which can induce autoimmune diseases. However, studies on the relationship between VOCs and RA are still unclear.

Functionalized 3D-printed GelMA/Laponite hydrogel scaffold promotes BMSCs recruitment through osteoimmunomodulatory enhance osteogenic via AMPK/mTOR signaling pathway.

The migration and differentiation of bone marrow mesenchymal stem cells (BMSCs) play crucial roles in bone repair processes. However, conventional scaffolds often lack of effectively inducing and recruiting BMSCs. In our study, we present a novel approach by introducing a 3D-bioprinted scaffold composed of hydrogels, with the addition of laponite to the GelMA solution, aimed at enhancing scaffold performance.

Fe, N, S co-doped cellulose paper carbon fibers as an air-cathode catalyst for microbial fuel cells.

The heteroatoms and transition metal co-doped carbon-based catalysts are an important way to improve the catalytic activity of oxygen reduction reaction (ORR). Herein, we reported a facile method to obtain iron, nitrogen, and sulfur co-doped cellulose paper carbon fibers as catalysts (Fe-N-S/CFs) for ORR in microbial fuel cells (MFCs) with the adsorption recovery of Congo red molecules from dye wastewater. The thermal treatment promoted the etching of carbon surface by ferric ions, resulting in increased surface roughness for forming the defective carbon structure.

Analysis of the biological activities of Saccharomyces cerevisiae expressing intracellular EGF, extracellular EGF, and tagged EGF in early-weaned rats.

A growing number of studies suggest that epidermal growth factor (EGF) plays an important role in early-weaned animals. The objective of this experiment was to compare the biological activity of intracellularly expressed EGF (IE-EGF), extracellularly expressed EGF (EE-EGF), and tagged EGF (T-EGF) from Saccharomyces cerevisiae (S. cerevisiae) both in vivo and in vitro.

TWEAK/Fn14 promotes the proliferation and collagen synthesis of rat cardiac fibroblasts via the NF-кB pathway.

We wished to elucidate a potential role of the tumor necrosis factor-like weak inducer of apoptosis (TWEAK)/fibroblast growth factor-inducible molecule 14 (Fn14) axis in myocardial fibrosis. Stimulation of neonatal rat cardiac fibroblasts (CFs) with TWEAK could increase CFs numbers and collagen synthesis. Conversely, when CFs were pretreated with siRNA against Fn14, induction of cell proliferation and collagen synthesis by TWEAK were inhibited.

[Adult oviposition and larvae feeding behavior of Spodoptera litura (Lepidoptera: Noctuidae) on tobacco plants after infested by B-biotype Bemisia tabaci (Homoptera: Aleyrodidae)].

To understand the effects of the defense responses of tobacco plants induced by the infesting of B-biotype Bemisia tabaci to Spodoptera litura, and to explore the mechanisms of the interspecific interactions between B-biotype B. tabaci and S. litura, a laboratory experiment was conducted to study the effects of tobacco plants after infested by B-biotype B.
