Abstract	Objective To investigate the role of NMDAR-cADPR-RyRs signaling pathway in remifentanil-induced hyperalgesia(RIH). Methods The rat model of postoperative hyperalgesia induced by remifentanil was established. SD rats were randomly divided into 6 groups as: control group, model group, RIH group, RIH+saline group, RIH+ketamine group and RIH+8-Br-cADPR group with 6 animals in each. N-methy-D-aspartic acid receptor(NMDA) antagonist ketamine or cyclic ADP-ribose(cADPR) antagonist 8-Br-cADPR was injected intrathecally 30 minutes before surgical operation in group RIH+ketamine and group RIH+8-Br-cADPR respectively. PWMT and PWTL were measured before operation and on the 1st, 2nd and 3rd days after operation. Western blotwas used to detect the protein level of p-NR2B, p-CaMKII, RyR1 and RyR3 in spinal dorsal horn neurons. The concentration of cADPR was measured by enzyme cycling assay. Results Compared with model group, PWMT and PWTL in RIH group decreased significantly on the first and the second day after remifentanil infusion, while p-NR2B, p-CaMKII, RyR1, RyR3 and cADPR in the spinal dorsal horn increased significantly (P＜0.05). After intrathecal injection of ketamine or 8-Br-cADPR, hypersensitivity to mechanical pain and thermal pain was alleviated in RIH+ketamine group and RIH+8-Br-cADPR group, and the expression level of p-NR2B, p-CaMKII, RyR1, RyR3 and cADPR decreased as compared with RIH group (P＜0.05). Conclusions Remifentanil-induced postoperative hyperalgesia of rat is attenuated by blocking NMDAR-cADPR-RyRs signaling pathway.

Abstract	Transport of graphene-based nanomaterials in porous media is closely related to background cations. This study examines the impacts of ionic specificity on the mobility of graphene oxide (GO) and reduced GO (RGOs) in saturated quartz sand. The transport of GO/RGOs as affected by monovalent cation Na⁺ followed extended Derjaguin-Landau-Verwey-Overbeek (XDLVO) theory, whereas in solutions containing multivalent cations Zn²⁺ and Al³⁺, cation bridging effect played a dominant role in the transport inhibition. Moreover, the adverse effects of the divalent cations on GO/RGOs migration obeyed the Hofmeister series, i.e. following the order of Pb²⁺ > Cd²⁺ > Zn²⁺. Batch adsorption experiments and DFT calculations further confirmed that cations of higher valences, and of the same valence but with larger ionic radii (smaller hydrated radii) interacted more strongly with GO/RGOs and sand grains via forming inner-sphere complexes. Thus, more favorable retention was observed through cation bridging between particles and collectors, and also via enhanced straining caused by particles aggregation. Furthermore, the sulfide-reduced GO (SR-GO) that contained more surface O-functional groups was impacted more remarkably by strong complexing cations than the pristine GO (P-GO), while the mobility of poorly functionalized irradiation-reduced GO (IR-GO) was less affected by cation bridging effect.

Abstract	The threat of microplastics (MPs) intervention in cropland always results in water flow alteration, which is the leading cause behind MP transport and distribution. This study investigated water infiltration and MP transport and distribution on MP‐contaminated silt loam and loamy sand to explore how water flow and MP affect each other and reveal their mechanisms. The results indicated that water infiltration increased as the content of MPs present in the soils increased from 1 to 7% (w/w), which increased the MPs in deeper soil layers. For the silt loam sample, the MP concentration first increased to higher levels at 15–20 cm and then decreased. The MPs with sizes of 0–150 and 150–500 μm were found in excess at 25‐to‐30‐cm and 5‐to‐20‐cm depths, respectively. In the case of the loamy sand sample, the MP concentration gradually increased up to 30‐cm depth, and the MPs with sizes of 0–150 and 150—500 μm were found in excess at 5‐to‐10‐cm and 15‐to‐30‐cm depths, respectively. The increased infiltration was due to the increased hydraulic conductivity resulting from inhibition of soil particle aggregation, increased soil porosity, and strong hydrophobicity of MP particles. The difference in proportions of various MP particle sizes in soil layers was due to the differences in migration ability in pores for various soil samples and MP particle aggregation features.

Abstract	Objectives: Post-traumatic stress disorder (PTSD) is characterized by recurrent episodes of severe anxiety after exposure to traumatic events. It is believed that these episodes are triggered at least in part by environmental stimuli associated with the precipitating trauma through classical conditioning, termed conditioned fear. However, traditional methods of conditioned fear memory extinction are frequently ineffective for PTSD treatment due to the contribution of non-associative sensitization caused by trauma. Anesthetics have shown promise for treating various psychiatric diseases such as depression. Methods: In this study, we examined if the inhaled anesthetic sevoflurane can suppress stress-enhanced fear learning (SEFL) in PTSD model mice. Model mice exposed to 2.4% sevoflurane for 6 h exhibited reduced freezing time and behavioral anxiety compared to sham-treated model mice. To explore the underlying mechanisms, we evaluated the regional expression levels of glucocorticoid receptors (GRs), cannabinoid CB1 receptors (CB1Rs), D1 dopamine receptors (D1Rs), and D2 dopamine receptors (D2Rs). Results: We verified that both GR and CB1R were significantly upregulated in the hippocampus, amygdaloid nucleus, and prefrontal cortex (PFC) of model mice, while D1R and D2R were downregulated. All of these expression changes were partially normalized in the PFC by 6 h but not with 2 h sevoflurane exposure. Conclusions: These results showed that sevoflurane exposure following traumatic events may be an effective treatment for PTSD.

Abstract	Graphene oxide (GO) is a representative novel carbonaceous nanomaterial, and neonicotinoid insecticides (NEOs) are currently the insecticides with the highest market share in the world. Their widespread application deservedly leads to their release to the environment. Thus, the complex interactions of these two types of organic compounds have attracted extensive attention. In this study, the effects of GO and its derivatives, reduced GO (RGO) and oxidized GO (OGO), on the photolysis of imidacloprid (IMD) (a typical NEO) under ultraviolet (UV) irradiation were systematically investigated. The results showed that the presence of the graphene-based nanomaterials (GNs) largely depressed the photodegradation of IMD, and the inhibition degree followed the order of RGO > GO > OGO. This was because the sp² π-conjugated structure in the GNs caused light-shielding effect and attenuated the direct photolysis of IMD, even though the GNs-generated reactive oxygen species (ROS) promoted the indirect photodegradation of IMD to a certain extent. Additionally, the rich O-functionalized GO and OGO altered the photolysis pathway of IMD and induced more toxic intermediate products. These results highlight the implication of carbonaceous nanomaterials on the behavior, fate and potential risk of NEOs in aqueous systems.

Abstract	Nowadays, nanohybrids (NHs) play a vital role in various application fields due to their multifunctional properties and are expected to be discharged to the environment inevitably, both intentionally and unintentionally. The underlying negative effects driven by the exposure, migration, toxicity and implication of NHs have attracted widespread attention, whereas literatures regarding these crucial issues have not yet been systematically reviewed so far. The objective of this review is to provide a comprehensive overview to identify the specific environmental processes (i.e., aggregation, transport and possible transformation routes) of NHs. Researches on the interaction between NHs and other coexisting substances in the environment are discussed, and the adverse effects of NHs on organisms are also identified, with emphasis on the interplay of materials properties and environmental parameters determining the occurrence, fate and implication of NHs. The challenges and future research directions towards the environmental behavior, implication, and risk of NHs are also proposed.

Abstract	While the homoaggregation of nanoplastics (NPs) has received a great deal of attention, their heteroaggregation with natural colloids is not well understood. In this study, the heteroaggregation behavior and mechanism of polystyrene nanoplastics (PSNPs) with hematite nanoparticles (HemNPs) were comprehensively investigated. The increase in the PS/HemNP mass concentration ratio led to a corresponding increase in the heteroaggregation rate, with the optimal heteroaggregation occurring at a PS/HemNP ratio of 0.0372. The primary heteroaggregation via electrostatic attraction and secondary heteroaggregation via interactions between the PS-HemNP agglomerates were the predominant heteroaggregation mechanisms. Specifically, the aquatic environmental factors had a great impact on the heteroaggregation processes, whereby the presence of Suwannee River humic acid (SRHA) (selected as a representative example of natural organic matter (NOM)) induced a remarkable heteroaggregation inhibition effect due to charge neutralization and steric repulsion. An increasing in pH weakened the electrostatic attraction between the particles, and resulted in a disaggregation of the PS-HemNP agglomerates. Furthermore, the heteroaggregation of the PSNPs with HemNPs formed large PS-HemNP agglomerates and shielded a number of available adsorption sites for perfluorooctanoic acid (PFOA) and perfluorooctane sulfonic acid (PFOS), resulting in the reduction of their adsorption removal by the agglomerates.

Abstract	Objectives: Long-term isoflurane anesthesia exposure could result in postoperative cognitive dysfunction (POCD). Preoperative stress is also reported to be a risk factor of POCD. However, it is unknown whether acute stress could impair memory after long-term isoflurane anesthesia. Methods: In this study, we categorized the mice with acute stress into mild (30 min restraint stress), moderate (60 min restraint stress), and severe (120 min restraint stress) stress groups and then we used Open-Field Test (OFT) to detect whether different scales of acute restraint stress successfully induced acute stress in mice. The memory performance of mice was measured using contextual and cued memory test, and the brain-derived neurotrophic factor protein levels of hippocampus was detected by Western blot. Results: We verified that mild stress has pro-cognitive effect, but severe stress has amnestic effect. Moreover, we found that mild and moderate other than severe acute stress could partially attenuate the memory impairment induced by long-term isoflurane anesthesia. Conclusion: Mild and moderate acute stress could partially attenuate the memory impairment induced by long-term isoflurane anesthesia.
