Exploring the impact of the use of ChatGPT on foreign language self-efficacy among Chinese students studying abroad: The mediating role of foreign language enjoyment.

Against the backdrop of rapid globalisation, Chinese students studying abroad face increasing challenges in foreign language learning and adapting to foreign language environments. This study surveyed 712 Chinese students studying abroad and used AMOS to examine the logical relationships between the use of ChatGPT, foreign language self-efficacy and foreign language enjoyment, as well as the mediating role of foreign language enjoyment in the use of ChatGPT and foreign language self-efficacy. The results indicated that the use of ChatGPT has a significant positive impact on both the foreign language self-efficacy and foreign language enjoyment of Chinese students studying abroad.

Fullerenols as efficient ferroptosis inhibitor by targeting lipid peroxidation for preventing drug-induced acute kidney injury.

Acute kidney injury (AKI) is characterized by rapid and significant deterioration of renal function over a short duration with high mortality. However, the intricate pathophysiological mechanisms underlying AKI have hindered the development of effective therapeutic strategies. Recent research has highlighted the crucial role of ferroptosis in the pathogenesis of AKI and has identified it as a promising therapeutic target.

Added value of histogram analysis of intravoxel incoherent motion and diffusion kurtosis imaging for the evaluation of complete response to neoadjuvant therapy in locally advanced rectal cancer.

Objective: To evaluate how intravoxel incoherent motion (IVIM) and diffusion kurtosis imaging (DKI) histogram analysis contribute to assessing complete response (CR) to neoadjuvant therapy (NAT) in locally advanced rectal cancer (LARC).

Pulmonary Crystal-Storing Histiocytosis Misdiagnosed as Lung Cancer.

Background: Crystalloid storage histiocytosis (CSH) is a rare clinical condition characterized by abnormally high numbers of histiocytes with a large accumulation of crystalline immunoglobulins. Due to its relative rarity, clinical diagnosis of it is frequently incomplete or incorrect. We report a case with pulmonary crystal-storing histiocytosis that was mistakenly identified as lung carcinoma.

Quercetin prevents methylmercury-induced mitochondrial dysfunction in the cerebral cortex of mice.

Methylmercury (MeHg) exposure can cause nerve damage and mitochondrial dysfunction. Mitochondrial dysfunction is mainly mediated by mitochondrial biogenesis and mitochondrial dynamics disorders. Quercetin (QE) plays an important role in activating silencing information regulator 2 related enzyme 1 (SIRT1), and SIRT1 activates peroxisome-proliferator-activated receptor-γ co-activator 1α (PGC-1α), which can regulate mitochondrial biogenesis and mitochondrial dynamics.

Polyphenol nanoparticles based on bioresponse for the delivery of anthocyanins.

Anthocyanin (AN) has good antioxidant and anti-inflammatory bioactivities, but its poor biocompatibility and low stability limit the application of AN in the food industry. In this study, core-shell structured carriers were constructed by noncovalent interaction using tannic acid (TA) and poloxamer 188 (F68) to improve the biocompatibility, stability and smart response of AN. Under different treatment conditions, TA-F68 and AN were mainly bound by hydrophobic interaction.

Further, chondroitin sulfate (CS) was utilized to achieve color-enhanced and homeostatic effects on PC-BA, and κ-carrageenan (KC) - starch complex was exploited as printing ink to construct oral film system.

Potential of Milk-Derived Extracellular Vesicles as Carriers for Oral Delivery of Active Phytoconstituents.

Extracellular vesicles (EVs) play a crucial role in intercellular communication and have the potential to serve as in vivo carriers for delivering active molecules. The biocompatibility advantages of EVs over artificial nanocarriers create new frontiers for delivering modern active molecules. Milk is a favorable source of EVs because of its high bioavailability, low immunogenicity, and commercial producibility.

Asymptomatic spinal lesions in patients with AQP4-IgG-positive NMOSD: A real-world cohort study.

Objective: This study aims to explore the frequency and influencing factors of asymptomatic spinal lesions (ASLs) and their impact on subsequent relapses in patients with AQP4-IgG-positive NMOSD (AQP4-NMOSD) in a real-world setting.

Methods: We retrospectively reviewed clinical information and spinal MRI data from AQP4-NMOSD patients who had at least one spinal cord MRI during their follow-ups. Kaplan-Meier curves and Cox proportional hazards models were employed to ascertain potential predictors of remission ASLs and to investigate factors associated with subsequent relapses.

Somatosensory cortex and central amygdala regulate neuropathic pain-mediated peripheral immune response via vagal projections to the spleen.

Pain involves neuroimmune crosstalk, but the mechanisms of this remain unclear. Here we showed that the splenic T helper 2 (T2) immune cell response is differentially regulated in male mice with acute versus chronic neuropathic pain and that acetylcholinergic neurons in the dorsal motor nucleus of the vagus (ACh) directly innervate the spleen. Combined in vivo recording and immune cell profiling revealed the following two distinct circuits involved in pain-mediated peripheral T2 immune response: glutamatergic neurons in the primary somatosensory cortex (Glu)→ACh→spleen circuit and GABAergic neurons in the central nucleus of the amygdala (GABA)→ACh→spleen circuit.

N-acetylcysteine protects against neurodevelopmental injuries induced by methylmercury exposure during pregnancy and lactation.

As an extremely dangerous environmental contaminant, methylmercury (MeHg) results in detrimental health effects in human brain nervous system, one of its main targets. However, as a developmental toxicant, the brain of offspring is vulnerable to MeHg during pregnancy and lactation exposure. Unfortunately, mechanisms of neurodevelopmental injuries induced by MeHg have not been fully elucidated.

Cadmium promotes the binding and centrosomal translocation of CCDC85C and PLK4 via ROS-GCLM pathway to trigger centrosome amplification in colon cancer cells.

However, anthocyanin homeostasis in oral film is a prerequisite for achieving efficient absorption and utilization of anthocyanin. Herein, three sulfated polysaccharides, including chondroitin sulfate (CS), fucoidin (FU) and λ-carrageenan (λ-CG), were complexed with blueberry anthocyanin (BA) to prepare oral film formulations using hydroxypropyl methylcellulose (HPMC) as a film-forming matrix.

Study of ATF4/CHOP axis-mediated mitochondrial unfolded protein response in neuronal apoptosis induced by methylmercury.

Methylmercury (MeHg) is a widely distributed environmental pollutant that can easily cross the blood-brain barrier and accumulate in the brain, thereby damaging the central nervous system. Studies have shown that MeHg-induced mitochondrial damage and apoptosis play a crucial role in its neurotoxic effects. Mitochondrial unfolded protein response (UPR) is indispensable to maintain mitochondrial protein homeostasis and ensure mitochondrial function, and the ATF4/CHOP axis is one of the signaling pathways to activate UPR.
