Hydrogen peroxide (HO) is a stable reactive oxygen species (ROS) in aquatic environment, and high concentration of ambient HO may directly or indirectly affect aquatic animal health. However, the response mechanism of fish to ambient HO has not been well studied yet. Therefore, the aim of the study was to investigate the immune, inflammatory, autophagic and DNA damage responses to long-term HO exposure in different tissues of common carp.

However, NSCLC patients are inclined to develop acquired gefitinib drug resistance through nowadays, unarticulated mechanisms of chemoresistance. Here, we investigated the role of TF (Trifolium flavonoids) on sensitizing gefitinib resistance in NSCLC cells and revealed its potential mechanism of action.

To extend its practicality in electrically conductive applications, it is necessary to confer electrical conductivity to the insulating wood. The most common strategy is to derive carbonized wood powder via an annealing process.

To elucidate the underlying mechanisms of contraction and inflammatory response, we investigated the isolated human bladder smooth muscle cells (hBSMC) under pathological hydrostatic pressure (HP) mimicking the in vivo PBOO condition.
Methods: hBSMCs were subjected to HP of 200 cm H O to explore the contraction and inflammatory cytokine expression of hBSMC treated with β-adrenoceptors (ADRBs) and/or autophagy signaling pathway agonists and/or antagonists.
Many genes encoding CCT domain-containing proteins regulate flowering time. In rice (Oryza sativa), 41 such genes have been identified, but only a few have been shown to regulate heading date. Here, to test whether and how additional CCT family genes regulate heading date in rice, we classified these genes into five groups based on their diurnal expression patterns.

Any recommendations to improve a manufacturing process obviously must be effective, but also be robust, scalable, and with product quality comparable to the original process. In this study, we report that three different GS CHO cell lines developed in media containing a standard concentration of the selection agent methionine sulfoximine (MSX), but then exposed to increased MSX concentrations during seed train expansion, achieved titer increases of 10-19%.

Glyphosate (Gly) is an active ingredient of herbicide, its underlying toxicity on fish is still unclear. The aim of this study was to evaluate chronic toxicity of Gly on tilapia via determining antioxidative status, metabolism, inflammation and immune response. The fish were exposed to different concentrations of Gly (0, 0.

Hypercorticism was indeed described in schizophrenia and ultra-high-risk states, but its association with clinical outcome has yet to be demonstrated. The impact of stress through cortisol may vary depending on the expression level of genes related to the stress pathway.

Chemoimmunotherapy-induced antitumor immune response is highly dependent on tumor autophagy. When tumor cells are treated with chemoimmunotherapy, timely overactivated autophagy can not only lead more tumor cells to death, but also participate in the endogenous antigen presentation and immune stimulators secretion of dying cells, thus plays a vital role. However, timely and accurately overactivated tumor autophagy during chemoimmunotherapy is of great difficulty.
