Abstract
OBJECTIVES Influenza affects a considerable proportion of the global population each year, and meteorological conditions may have a significant impact on its transmission. In this study, we aimed to develop a prediction model for the number of influenza patients at the national level using satellite images and provide a basis for predicting influenza through satellite image data. STUDY DESIGN We developed an influenza incidence prediction model using satellite images and influenza patient data. METHODS We collected satellite images and daily influenza patient data from July 2014 to June 2019 and developed a convolutional long short-term memory (LSTM)-LSTM neural network model. The model with the lowest average of mean absolute error (MAE) was selected. RESULTS The final model showed a high correlation between the predicted and actual number of influenza patients, with an average MAE of 5.9010 per million population. The model performed best with a 2-week time sequence. CONCLUSIONS We developed a national-level prediction model using satellite images to predict influenza incidence. The model offers the advantage of nationwide analysis. These results may reduce the burden of influenza by enabling timely public health interventions.

Abstract
The removal of uranyl ions (UO2 2+) from water is challenging due to their chemical stability, low concentrations, complex water matrix, and technical limitations in extraction and separation. Herein, a novel molybdenum disulfide/graphene oxide heterojunction (MoS2/GO-H) is developed, serving as an effective electrode for capacitive deionization (CDI). By combining the inherent advantages of electroadsorption and electrocatalysis, an innovative electroadsorption-electrocatalysis system (EES) strategy is introduced. This system utilizes interface polarization at the MoS2 and GO interface, creating an additional electric field that significantly influences carrier behavior. The MoS2/GO-H electrode, with its extraordinary adsorption capacity of 805.57 mg g-1 under optimal conditions, effectively treated uranium-laden wastewater from a mine, achieving over 90% removal efficiency despite the presence of numerous competing ions at concentrations significantly higher than UO2 2+. Employing density functional theory (DFT) and ab initio molecular dynamics (AIMD) simulations, it is found that the MoS2/GO-H total charge density at the Fermi level, enhanced by interfacial polarization, surpasses that of separate MoS2 and GO, markedly boosting conductivity and electrocatalytic effectiveness.

Abstract
Intracellular DNA sensors regulate innate immunity and can provide a bridge to adaptive immunogenicity. However, the activation of the sensors in antigen-presenting cells (APCs) by natural agonists such as double-stranded DNAs or cyclic nucleotides is impeded by poor intracellular delivery, serum stability, enzymatic degradation and rapid systemic clearance. Here we show that the hydrophobicity, electrostatic charge and secondary conformation of helical polypeptides can be optimized to stimulate innate immune pathways via endoplasmic reticulum stress in APCs. One of the three polypeptides that we engineered activated two major intracellular DNA-sensing pathways (cGAS-STING (for cyclic guanosine monophosphate-adenosine monophosphate synthase-stimulator of interferon genes) and Toll-like receptor 9) preferentially in APCs by promoting the release of mitochondrial DNA, which led to the efficient priming of effector T cells. In syngeneic mouse models of locally advanced and metastatic breast cancers, the polypeptides led to potent DNA-sensor-mediated antitumour responses when intravenously given as monotherapy or with immune checkpoint inhibitors. The activation of multiple innate immune pathways via engineered cationic polypeptides may offer therapeutic advantages in the generation of antitumour immune responses.

Abstract
The complexity and heterogeneity of individual tumors have hindered the efficacy of existing therapeutic cancer vaccines, sparking intensive interest in the development of more effective in situ vaccines. Herein, we introduce a cancer nanovaccine for reactive oxygen species-augmented metalloimmunotherapy in which FeAl-layered double hydroxide (LDH) is used as a delivery vehicle with dihydroartemisinin (DHA) as cargo. The LDH framework is acid-labile and can be degraded in the tumor microenvironment, releasing iron ions, aluminum ions, and DHA. The iron ions contribute to aggravated intratumoral oxidative stress injury by the synergistic Fenton reaction and DHA activation, causing apoptosis, ferroptosis, and immunogenic cell death in cancer cells. The subsequently released tumor-associated antigens with the aluminum adjuvant form a cancer nanovaccine to generate robust and long-term immune responses against cancer recurrence and metastasis. Moreover, Fe ion-enabled T1-weighted magnetic resonance imaging can facilitate real-time tumor therapy monitoring. This cancer-nanovaccine-mediated metalloimmunotherapy strategy has the potential for revolutionizing the precision immunotherapy landscape.

Abstract
Near-infrared (NIR) laser-induced photoimmunotherapy has aroused great interest due to its intrinsic noninvasiveness and spatiotemporal precision, while immune evasion evoked by lactic acid (LA) accumulation severely limits its clinical outcomes. Although several metabolic interventions have been devoted to ameliorate immunosuppression, intracellular residual LA still remains a potential energy source for oncocyte proliferation. Herein, an immunomodulatory nanoadjuvant based on a yolk-shell CoP/NiCoP (CNCP) heterostructure loaded with the monocarboxylate transporter 4 inhibitor fluvastatin sodium (Flu) is constructed to concurrently relieve immunosuppression and elicit robust antitumor immunity. Under NIR irradiation, CNCP heterojunctions exhibit superior photothermal performance and photocatalytic production of reactive oxygen species and hydrogen. The continuous heat then facilitates Flu release to restrain LA exudation from tumor cells, whereas cumulative LA can be depleted as a hole scavenger to improve photocatalytic efficiency. Subsequently, potentiated photocatalytic therapy can not only initiate systematic immunoreaction, but also provoke severe mitochondrial dysfunction and disrupt the energy supply for heat shock protein synthesis, in turn realizing mild photothermal therapy. Consequently, LA metabolic remodeling endows an intensive cascade treatment with an optimal safety profile to effectually suppress tumor proliferation and metastasis, which offers a new paradigm for the development of metabolism-regulated immunotherapy.

Abstract
To counteract the high level of reactive oxygen species (ROS) caused by rapid growth, tumor cells resist oxidative stress by accelerating the production and regeneration of intracellular glutathione (GSH). Numerous studies focus on the consumption of GSH, but the regeneration of GSH will enhance the reduction level of tumor cells to resist oxidative stress. Therefore, inhibiting the regeneration of GSH; while, consuming GSH is of great significance for breaking the redox balance of tumor cells. Herein, a simple termed MnOx -coated Au (AMO) nanoflower, as a nicotinamide adenine dinucleotide phosphate (NADPH) oxidase (NOX) nanoenzyme, is reported for efficient tumor therapy. Au nanoparticles exhibit the capability to catalyze the oxidation of NADPH, hindering GSH regeneration; while, concurrently functioning as a photothermal agent. During the process of eliminating intracellular GSH, MnOx releases Mn2+ that subsequently engages in Fenton-like reactions, ultimately facilitating the implementation of chemodynamic therapy (CDT). Overall, this NOX enzyme-based nanoplatform enhances ROS generation and disrupts the state of reduction equilibrium, inducing apoptosis and ferroptosis by blocking GSH regeneration and increasing GSH consumption, thereby achieving collaborative treatments involving photothermal therapy (PTT), CDT, and catalytic therapy. This research contributes to NADPH and GSH targeted tumor therapy and showcases the potential of nanozymes.

Abstract
AIMS Planning regulations have been used to prevent the over-proliferation of hot food takeaways, minimising the impact of local obesogenic environments. To help mitigate the effects of lockdown, the UK government introduced temporary changes in March 2020 to Planning Regulations for England, allowing food retailers to open for takeaway services beyond 'ancillary' level without needing to apply for planning permission through permitted development rights (PDR). Businesses are required to notify their local authority (LA) when they implement PDRs. To better understand the impact of regulations on the policy and practice of key professional groups, Public Health England commissioned Teesside University to undertake scoping research in the North East of England. METHODS A focus group and interviews were conducted with 15 professionals from 7 of 12 North East LAs. Professions included Planners, Public Health Leads, Environmental Health Officers and Town Centre Managers. Data were analysed using a codebook thematic analysis approach. An interpretation meeting with some participants was conducted. RESULTS LAs were not aware of most businesses notifying them of new regulation adherence despite taking up PDRs, but were considered low-priority with many lacking formal recording procedures. There were concerns about health consequences of the changes, and consensus relating to ongoing issues with capacity across all professional groups, largely due to the continuing pandemic and absence of a strategy out of temporary measures. Concerns existed around ensuring cessation of restaurants trading as takeaways, and hygiene inspections backlog. Many (personally) saw new takeaways as a lifeline, offering broader menus and preserving local economies. CONCLUSION Lack of information around the number of restaurants/pubs using PDR to trade as takeaway services, ongoing capacity issues of LAs and, at the time, the absence of a strategy post regulation changes, meant there were high levels of uncertainty regarding the impacts of these temporary measures.

Abstract
STUDY OBJECTIVE Latino youths in the United States experience disproportionately high rates of teen pregnancy. The aim of this study was to obtain expecting and parenting Latino adolescents' perspectives regarding factors contributing to teen pregnancy and pregnancy prevention. METHODS Expecting/parenting Latino adolescents were recruited from high schools with high proportions of Latino youths and teen pregnancy. Participants completed a questionnaire on sociodemographic and background characteristics. Focus groups were stratified by age and gender and audio recorded. Grounded theory was used to identify themes from the transcribed audio recordings. RESULTS Thirty-two expecting/parenting Latino adolescents (20 females, 12 males) 14-19 years old participated in four focus groups. Quantitative results revealed that two-thirds of participants at birth had adolescent mothers. Over three-quarters of participants reported that their pregnancies had occurred too soon. Qualitative themes for factors contributing to teen pregnancy included lack of contraceptive knowledge/access, belief of invincibility, influence within relationships, male decisions on contraceptive use, desire to belong among peers, lack of parental support for contraceptive use, lack of parental attention, rebellion, normalization of adolescent parenthood in Latino culture, and media. Themes for pregnancy prevention included time alone with physicians, parenting teens as mentors, reproductive health education, and community pregnancy-prevention programs. CONCLUSION Multiple factors contribute to teen pregnancy in Latino youth, including influences from Latino culture, family, peers, partners, and social determinants of health. Pregnancy prevention should incorporate interventions to address these aspects, including disseminating culturally sensitive education materials, providing parenting teens as peer mentors, encouraging time alone with health care providers, and addressing various social determinants of health.

Abstract
We report the first evidence that the gist mechanism of fuzzy-trace theory and the associative mechanism of activation monitoring theory operate in parallel, in the recall version of the Deese/Roediger/McDermott illusion. In three experiments, we implemented a new methodology that allows their respective empirical indexes, gist strength (GS) and backward associative strength (BAS), to each be manipulated while the other is held constant. In Experiment 1, increasing GS increased false recall of missing words, but increasing BAS did not. In Experiments 2 and 3, however, increasing GS and increasing BAS both increased recall of missing words, and those effects were independent and additive. In all three experiments, GS and BAS affected true recall of list words in qualitatively different ways: (a) Increasing GS always improved true recall, regardless of whether BAS was high or low, but (b) increasing BAS impaired true recall when GS was high and improved true recall when GS was low. To pinpoint the retrieval loci of the two variables' effects, we analyzed the data of all experiments with the dual-retrieval model. Those analyses showed that the variables' respective effects were due to different retrieval processes. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

Abstract
As endocrine hormones, glucocorticoids (GCs) play a pivotal role in numerous physiological processes, including mammary growth and lactation, circulatory metabolism, and responses to external stimuli. In the dairy industry, milk production from cows or goats is important for newborns and economic benefits. However, the milk yields from ruminant animals are always affected by the extent of mammary development, mammary disease, stress, or changes in metabolism. Thus, it is necessary to clarify how GCs changes in ruminants affect ruminant mammary gland function and mammary disease. This review summarizes the findings identifying that GCs modulate mammary gland development before lactation, but the stress-induced excessive release of GCs leads to milk production loss. In addition, the manner of GCs release may change under different concentrations of metabolites or during mastitis or inflammatory challenge. Nevertheless, exogenous GCs administration to animals may alleviate the clinical symptoms of mastitis. This review demonstrates that GCs offer a fascinating contribution to both physiologic and pathogenic conditions of the mammary gland in ruminant animals. Characterizing and understanding these changes or functions of endogenous and exogenous GCs in animals will be crucial for developing more endocrine regulators and therapies for improving milk production in ruminants.

Abstract
AIMS To explore existing regulatory mechanisms to restrict hot food takeaway (HFT) outlets through further understanding processes at local and national levels. METHODS The Planning Appeals Portal was utilised to identify recent HFT appeal cases across England between December 2016 and March 2020. Eight case study sites were identified using a purposive sampling technique and interviews carried out with 12 professionals involved in planning and health to explore perceptions of and including factors that may impact on the HFT appeal process. Additionally, documents applicable to each case were analysed and a survey completed by seven Local Authority (LA) health professionals. To confirm findings, interpretation meetings were conducted with participants and a wider group of planning and public health professionals, including a representative from the Planning Inspectorate. RESULTS Eight case study sites were identified, and 12 interviews conducted. Participants perceived that LAs would be better able to work on HFT appeal cases if professionals had a good understanding of the planning process/the application of local planning policy and supplementary planning documents; adequate time and capacity to deal with appeals cases; access to accurate, robust, and up to date information; support and commitment from elected members and senior management; good lines of communication with local groups/communities interested in the appeal; information and resources that are accessible and easy to interpret across professional groups. CONCLUSIONS Communication across professional groups appeared to be a key factor in successfully defending decisions. Understanding the impact of takeaway outlets on health and communities in the long term was also important. To create a more robust appeals case and facilitate responsiveness, professionals involved in an appeal should know where to locate current records and statistical data. The enthusiasm of staff and support from senior management/elected officials will play a significant role in driving these agendas forward.

Abstract
The recent success of mRNA therapeutics against pathogenic infections has increased interest in their use for other human diseases including cancer. However, the precise delivery of the genetic cargo to cells and tissues of interest remains challenging. Here, we show an adaptive strategy that enables the docking of different targeting ligands onto the surface of mRNA-loaded small extracellular vesicles (sEVs). This is achieved by using a microfluidic electroporation approach in which a combination of nano- and milli-second pulses produces large amounts of IFN-γ mRNA-loaded sEVs with CD64 overexpressed on their surface. The CD64 molecule serves as an adaptor to dock targeting ligands, such as anti-CD71 and anti-programmed cell death-ligand 1 (PD-L1) antibodies. The resulting immunogenic sEVs (imsEV) preferentially target glioblastoma cells and generate potent antitumour activities in vivo, including against tumours intrinsically resistant to immunotherapy. Together, these results provide an adaptive approach to engineering mRNA-loaded sEVs with targeting functionality and pave the way for their adoption in cancer immunotherapy applications.

Abstract
Numerous efforts have been devoted to understanding the electron transfer process of uranium (UO22+) on adsorbent materials, whereas the potential oxygen vacancies (OVs) in metal oxides have long been overlooked. Once these interactions are taken into account, the emerging molecular orbital effects undoubtedly affect the adsorption process. Here, we synthesized CC/γ-MnO2 by growing MnO2 on carbon cloth (CC), followed by the creation of oxygen vacancies (OVs) through electrochemical methods to form CC/γ-MnO2-OVs. The CC/γ-MnO2-OVs shows significantly enhanced selectivity and durability for UO22+, with the maximum adsorption capacity increasing from 456.8 to 1648.1 mg/g (by a factor of 3.6). Theoretical calculations suggest that the generation of OVs leads to an increase in charge transfer and a decrease in adsorption energy between UO22+ and CC/γ-MnO2, due to the interaction between Mn 3d orbital in CC/γ-MnO2 and O 2p orbital in UO22+. The OVs in CC/γ-MnO2 provide a spatial structure for anchoring the OU=O moiety of UO22+, while the surface van der Waals forces and the formation of chemical bonds between Mn-U contribute to charge interactions. This synergistic effect allows CC/γ-MnO2-OVs to exhibit favorable selectivity, a large adsorption capacity, and rapid adsorption kinetics towards uranyl ions. This work achieves enhanced UO22+ separation by introducing OVs in CC/γ-MnO2 through a facile electrochemical strategy, highlighting the great potential for nuclear waste processing.

Abstract
Rating norms for semantic attributes (e.g., concreteness, familiarity, valence) are widely used to study the content that people process as they encode meaningful material. Intensity ratings of individual attributes have been manipulated in numerous experiments with a range of memory paradigms, but those manipulations are contaminated by substantial correlations with the intensity ratings of other attributes. A method of controlling such contamination is needed, which requires a determination of how many distinct attributes there are among the large collection of attributes for which published norms are available. Identification of overlapping words in multiple rating projects yielded a data base containing normed values for each word's perceived intensity (M rating) and ambiguity (rating SD) on 20 different attributes. Principal component analyses then revealed that the intensity space was spanned by just three latent semantic attributes, and the ambiguity space was spanned by five. Psychologically, the big three intensity factors (emotional valence, size, age) were highly interpretable, as were the big five ambiguity factors (discrete emotion, emotional valence, age, meaningfulness, and verbatim memory). We provide a data base of intensity and ambiguity factor scores that can be used to conduct uncontaminated studies of the memory effects of the intensity and ambiguity of latent semantic attributes.

Abstract
The use of transposase in cell line development (CLD) programs has experienced increased popularity over the past decade. However, few studies have described the mechanism of action and the genomic and phenotypic characteristics of clones derived from transposase. Additionally, how these traits impact long-term bioproduction is unknown. Here, we use chromosome painting, deep sequencing, and ddPCR to characterize the unique fingerprints associated with transposase-derived clones. Transposase reduces the cellular pool of transient vector as early as three days post transfection following transfection and expedites stable pool establishment by up to two weeks. Furthermore, recombinant DNA expression is significantly improved up to ∼3 fold along with a greater balance of antibody heavy and light chain transcripts, resulting in higher titers in transposase generated pools. Transposase derived pools contained an often innumerable number of integration sites, representing a vast increase in integration site diversity over randomly generated pools, which were bottlenecked at 1-3 integration sites per pool. These transposase mediated integrations typically occurred in clean singlets, free of genomic scars such as deletions, inversions, and other modifications associated with legacy transfection methods which exhibited higher copy numbers per integration site. Relative declines in gene expression occur with copy number increase in the randomly generated, but not the transposase derived clones. Furthermore, transposase-derived clones were more likely to exhibit enhanced a long term stability profile, including product quality attributes such as mannose-5. This improved stability may result from circumventing mechanisms associated with the silencing of tandem repeats. Thus, transposase-mediated approaches can provide multifaceted molecular and phenotypic advantages in cell line development when compared to legacy random-integration methods.

Abstract
Objective: To investigate the clinical effects of the bow-tie adjustable suture technique in managing overcorrection in patients with intermittent exotropia after surgery. Methods: This was a retrospective case series study. Clinical data were collected from children with intermittent exotropia who underwent strabismus correction surgery, including the bow-tie adjustable suture technique and conventional techniques, at the Department of Strabismus and Pediatric Ophthalmology, Shanxi Eye Hospital, from January 2020 to September 2021. Children with postoperative esodeviation≥15 prism diopters (PD) within the first 6 days were treated differently based on the surgical technique and their individual conditions, including suture adjustment and conservative treatment. The overcorrection rate and its changes among different surgical groups, the recovery of ocular alignment and binocular visual function after different treatment methods in children with overcorrection on the sixth postoperative day, and the postoperative complications in different surgical groups were observed. Statistical analysis was performed using independent samples t-test, Wilcoxon rank-sum test, repeated-measures analysis of variance, Bonferroni test, chi-square test, or Fisher's exact probability test, as appropriate. Results: A total of 643 children who underwent intermittent exotropia correction surgery were included in the study. Among them, 325 children underwent the bow-tie adjustable suture technique, with 185 males and 140 females, and the mean age was (9.50±2.69) years. The remaining 318 children underwent conventional techniques, with 176 males and 142 females, and the mean age was (9.90±2.67) years. There were no statistically significant differences in age and gender distribution between the two surgical groups (all P>0.05). On the first postoperative day, among children who underwent the bow-tie adjustable suture technique, 40 had an esodeviation of≥10 PD, resulting in an overcorrection rate of 12.3% (40/325), while among children who underwent conventional techniques, 32 had an esodeviation of≥10 PD, resulting in an overcorrection rate of 10.1% (32/318). On the sixth postoperative day, these rates decreased to 5.5% (18/325) and 3.1% (10/318) in the two groups, respectively. At 1, 6, and 12 months postoperatively, the overcorrection rate in children who underwent the bow-tie adjustable suture technique was 0, while in children who underwent conventional techniques, the overcorrection rate did not show a significant decrease compared to before surgery. The differences between the two surgical groups were statistically significant (all P<0.05). On the sixth postoperative day, among children with an esodeviation of≥15 PD, 13 underwent suture adjustment and 7 received conservative treatment. The results of repeated-measures analysis of variance showed statistically significant differences in near and distance esodeviation angles among children who received different treatment methods (F=145.20, 106.87, both P<0.001), as well as statistically significant differences in near and distance esodeviation angles at different time points within each group of children (F=81.67, 35.09, both P<0.001). There were also significant differences in the trends of change in near and distance esodeviation angles at different time points among children who received different treatment methods (F=79.90, 36.73, both P<0.001). Further pairwise comparisons showed significant differences in near and distance esodeviation angles between the sixth postoperative day and 1, 6, and 12 months postoperatively in children who underwent suture adjustment (all P<0.05), while no statistically significant differences were observed in children who received conservative treatment (all P>0.05). At 12 months postoperatively, among the 13 children who underwent suture adjustment, 12 achieved stereopsis, while among the 7 children who received conservative treatment, all became stereo-blind after removing the prismatic correction. No serious complications occurred in any of the children postoperatively. Conclusion: The proportion of children with intermittent exotropia who achieved orthotropic alignment one year after surgery was relatively low among those who had an overcorrection of≥15 PD on the sixth postoperative day. The bow-tie adjustable suture technique is a simple and effective approach for managing overcorrection in patients with intermittent exotropia. Adjusting the sutures on the sixth postoperative day can reduce the overcorrection rate and is considered a safe and effective method.

Abstract
The desirable curative effect in clinical immunotherapy has been challenging due to the immunosuppressive tumor microenvironment (TME) with high lactic acid (LA) metabolism in solid tumors. Although targeting metabolic reprogramming of tumor cells can restore the survival and function of immune cells in the TME, it is also plagued by insufficient immunogenicity. Herein, an activatable immunomodulatory nanoadjuvant CuSe/CoSe2@syrosingopine (CSC@Syro) is constructed for simultaneously relieving immunosuppressive TME and boosting tumor immune response. Specifically, CuSe/CoSe2 (CSC) exhibits TME-activated glutathione (GSH) depletion and hydroxyl radical (•OH) generation for potential ferroptosis. Meanwhile, the remarkable photothermal conversion efficiency and elevated photocatalytic ROS level both promote CSC heterostructures to induce robust immunogenic cell death (ICD). Besides, the loaded syrosingopine inhibitor achieves LA metabolism blockade in cancer cells by downregulating the expression of monocarboxylate transporter 4 (MCT4), which could sensitize ferroptosis by intracellular milieu acidification and neutralize the acidic TME to alleviate immunosuppression. Hence, advanced metabolic modulation confers the potentiated immune infiltration of ICD-stimulated T lymphocytes and further reinforces antitumor therapy. In brief, CSC@Syro-mediated synergistic therapy could elicit potent immunogenicity and suppress tumor proliferation and metastasis effectually by integrating the tumor metabolic regulation and ferroptosis with immunotherapy.

Abstract
The outcome of laser-triggered plasmons-induced phototherapy, including photodynamic therapy (PDT) and photothermal therapy (PTT), is significantly limited by the hypoxic tumor microenvironment and the upregulation of heat shock proteins (HSPs) in response to heat stress. Mitochondria, the biological battery of cells, can serve as an important breakthrough to overcome these obstacles. Herein, dendritic triangular pyramidal plasmonic CuPt alloys loaded with heat-sensitive NO donor N, N'-di-sec-butyl-N, N'-dinitroso-1,4-phenylenediamine (BNN) is developed. Under 808 nm laser irradiation, plasmonic CuPt can generate superoxide anion free radicals (·O2 - ) and heat simultaneously. The heat generated can then trigger the release of NO gas, which not only enables gas therapy but also damages the mitochondrial respiratory chain. Impaired mitochondrial respiration leads to reduced oxygen consumption and insufficient intracellular ATP supply, which effectively alleviates tumor hypoxia and undermines the synthesis of HSPs, in turn boosting plasmonic CuPt-based PDT and mild PTT. Additionally, the generated NO and ·O2 - can react to form more cytotoxic peroxynitrite (ONOO- ). This work describes a plasmonic CuPt@BNN (CPB) triggered closed-loop NO gas, free radicals, and mild photothermal therapy strategy that is highly effective at reciprocally promoting antitumor outcomes.

Abstract
Rating norms for semantic attributes (e.g., concreteness, dominance, familiarity, and valence) are widely used in many psychological literatures to study the effects of processing specific types of semantic content. Word and picture norms for many attributes are available for thousands of items, but there is a contamination problem in experimentation. When an attribute's ratings are varied, how the semantic content that people process changes is unclear because ratings of individual attributes are correlated with ratings of so many other attributes. To solve this problem, the psychological space that 20 attributes occupy has been mapped, and factor score norms have been published for the latent attributes that generate that space (emotional valence, age-of-acquisition, and symbolic size). These latent attributes have yet to be manipulated in experimentation, and hence, their effects are unknown. We conducted a series of experiments that focused on whether they affect accuracy, memory organization, and specific retrieval processes. We found that (a) all three latent attributes affected recall accuracy, (b) all three affected memory organization in recall protocols, and (c) all three affected direct verbatim access, rather than reconstruction or familiarity. The memory effects of two of them (valence and age-of-acquisition) were unconditional, but memory effects were only detected for the third at particular levels of the other two. The key implications are that semantic attributes can now be cleanly manipulated, and when they are, they have broad downstream effects on memory.

Abstract
In recognition memory, anything that is objectively new is necessarily not-old, and anything that is objectively old is necessarily not-new. Therefore, judging whether a test item is new is logically equivalent to judging whether it is old, and conversely. Nevertheless, a series of 10 experiments showed that old? and new? judgments did not produce equivalent recognition accuracy. In Experiments 1-4, wherein subjects made old? or new? judgments about test items, new? judgments yielded more accurate performance for old items than old? judgments did, and old? judgments yielded more accurate performance for new items than new? judgments did. This same violation of logical equivalence was observed in Experiments 5-10, wherein subjects made similar? judgments as well as old? and new? ones. In short, old? and new? judgments displayed consistent Judgment × Item crossovers, rather than equivalence. Response latencies were used to test the hypothesis that Judgment × Item crossovers were due to certain judgment-item combinations provoking more deliberate, thorough retrieval than other combinations. There was no support for that hypothesis, but the data were consistent with an earlier theory, which posits that latency depends on the extent to which judgments or items slant retrieval toward accessing verbatim traces.

Abstract
Notwithstanding immune checkpoint blocking (ICB) therapy has made eminent clinical breakthroughs, overcoming immunologically "cold" tumors remains challenging. Here, a cascade potentiated nanomodulator AuPtAg-GOx is engineered for boosting immune responsiveness. Upon 1064 nm laser irradiation, AuPtAg-mediated mild photothermal therapy (PTT) activates cytotoxic T lymphocytes and reverses the immunogenic "cold" tumor microenvironment. Further, to amplify the thermal sensitivity of tumor cells, glucose oxidase (GOx) is introduced to suppress the production of heat shock proteins, thereby promoting mild photothermal therapy. Complementarily, AuPtAg nanozymes with catalase-like activity can ameliorate tumor hypoxia, significantly improving the GOx activity. As a result, the combination of AuPtAg-GOx with self-augmented photothermal ability and PD-L1 antibody can further escalate the antitumor efficacy. The AuPtAg-GOx-based synergistic starvation therapy, mild PTT, and immunotherapy cascade enhancement therapy strategy can be a favorable tool to effectively kill cancer cells.

Abstract
Objective: To investigate the short-term efficacy of the prism treatment in a manner of reducing prism diopters step by step for small-angle acute acquired concomitant esotropia (AACE). Methods: Retrospective case series study. The clinical data of 17 AACE patients with strabismus ≤25 prism degrees (PD) including 6 males and 11 females, aged 14 to 60 years, who underwent the prism treatment in the Strabismus and Pediatric Ophthalmology Clinic of Shanxi Eye Hospital from October 2018 to June 2020 were collected. The prism treatment was conducted by a step-by-step reduction of prism diopters. An under-corrected prism was applied to the patient for the first time, and the degree of the prism was reduced gradually with the decrease in the degree of strabismus. Statistical analysis was performed after 6 months of treatment. The treatment success was defined as obtaining orthotropia and deleting diplopia when prism glasses were weaned off. The strabismus degree, Worth 4 dot test results, near stereopsis (Titmus stereopsis) and synoptophore fusion function before and after treatment were compared, and the factors affecting the curative effect were analyzed. Statistical methods mainly included paired t-test, Wilcoxon rank sum test, the Fisher exact test and univariate logistic regression analysis. Results: Among these 17 patients, 15 had myopia and 2 had emmetropia. Pretherapeutic esodeviation was (13.94±5.83) PD at near (33 cm), and was (15.76±5.24) PD at distance (6 m). After 6 months of treatment, 7 patients were successfully cured. The deviation angle at distance [(10.60±7.16) PD] and near [(9.80±6.00) PD] of the remaining 10 patients at 6 months after prismatic treatment was significantly smaller than that before treatment [(17.50±5.40) PD and (16.10±5.47) PD; t=3.69, 4.10; both P<0.01]. The Titmus stereogram showed that 2 cases had no stereopsis, 6 cases had peripheral stereopsis, 3 cases had macular stereopsis, and 6 cases had foveal stereopsis before treatment. Stereopsis was significantly improved at 6 months after prismatic treatment, with 3 cases havimg macular stereopsis and 14 cases having foveal stereopsis (Z=-2.99; P<0.01). The Worth-4-dot test disclosed that, the number of patients who saw four lamps at distance and near was 0 and 2 before treatment, and 7 and 9 after treatment, respectively, and the difference was statistically significant (both P<0.05). The divergent fusional amplitude and convergent fusional amplitude in the synoptophore at 6 month after treatment was not significantly different from that before treatment (both P>0.05). The efficacy of treatment was not significantly related to the duration from onset to treatment, the pretherapeutic esodeviation, the Titmus stereoacuity, cycloplegic refractive error, and age (all P>0.05). None of the 7 patients, who were successfully cured had a recurrence of esotropia or diplopia during the observation period of 6 to 24 months (median, 11 months). Conclusions: Prism treatment in a manner of step-by-step reduction of prism diopters can significantly diminish the degree of esotropia and improve the binocular function in small-angle AACE. Furthermore, some patients could be cured, achieving orthophoria without diplopia.

Abstract
At present, some progress has been made in the field of cancer theranostics based on nanocatalysts (NCs), but achieving precise theranostics in response to the specific tumor microenvironment (TME) remains a major challenge. Herein, a TME-responsive upconversion nanoparticles (UCNPs)-based smart UCNPs@Cu-Cys-GOx (UCCG) nanosystem is engineered, which combines natural enzymes and nanozymes so as to amplify reactive oxygen species (ROS) generation in situ for cancer starvation/chemodynamic/immunotherapy. One of the biggest merits of this material is that it can be preserved inert (off) in normal tissues, and only in the TME can it be specifically activated (on) through a series of enzymatic cascades to boost ROS production via a strategy of open source (H2 O2 self-supplying ability) and reduce expenditure (glutathione (GSH) consuming ability). More importantly, the enhanced oxidative stress by UCCG NCs reverses the immunosuppressive TME, and facilitates antitumor immune responses. Meanwhile, the starvation/chemodynamic synergistic therapy triggered by UCCG combined with PD-L1 antibody effectively inhibits the growth of primary tumors and cancer metastasis. In addition, the UCNPs in UCCG present upconversion luminescence enhancement, which can be exploited to visualize the reinforced ROS generation in real time. Collectively, this work provides an original method for the devising and exploitation of UCNPs-based catalytic immunotherapy.

In this review, we first introduce the various synthetic strategies of SAzymes, and the TME-responsive SAzymes activities. Next, the TME-responsive enhanced antitumor therapeutic approaches based on the enzymatic activities of SAzymes are summarized, and the corresponding therapy mechanisms are elaborated. Subsequently, a concise but concentrated summary, and the challenges and opportunities for the future design and engineering of SAzyme are outlined. As a newly-built discipline, SAzymes have vast space for development in enhanced antitumor therapy. This timely review provides guidance and constructive suggestions for the future of SAzymes.

Abstract
OBJECTIVE In the Alzheimer's Disease Neuroimaging Initiative (ADNI), cognitive function was tracked across multiple years by a comprehensive neuropsychological battery. In this study, we examined the latent structure of the ADNI battery and evaluated the invariance of that structure among diagnostic groups and over time. METHOD We used exploratory and confirmatory factor analyses to investigate the invariance of the ADNI battery's latent factor structure among three diagnostic groups (healthy controls, patients with mild cognitive impairment, patients with Alzheimer's disease) over a 2-year interval (baseline, 6 months, 12 months, 24 months). RESULTS The results revealed a five-factor structure for the ADNI battery (memory, visuospatial processing, attention, language, executive function). This structure displayed configural invariance but not weak, strong, or strict invariance across the three diagnostic groups. Longitudinally, configural, weak, strong, and strict invariance were all established within each diagnostic group, except that strict invariance was rejected in healthy controls. CONCLUSIONS The ADNI battery assesses the same cognitive abilities in the three diagnostic groups, but test scores do not calibrate to these abilities equally in the respective groups, making certain statistics (e.g., factor scores) noncomparable between groups. Within each group, the latent structure and the numerical relations between individual tests and underlying factors remained invariant over 2 years, suggesting that this battery is a reliable tool for tracking longitudinal changes in specific cognitive abilities within individual diagnostic groups.

Abstract
Of all the reaction oxygen species (ROS) therapeutic strategies, NIR light-induced photocatalytic therapy (PCT) based on semiconductor nanomaterials has attracted increasing attention. However, the photocatalysts suffer from rapid recombination of electron-hole pairs due to the narrow band gaps, which are greatly restricted in PCT application. Herein, Bi2 Se3 /Au heterostructured photocatalysts are fabricated to solve the problems by introducing Au nanoparticles (NPs) in situ on the surface of the hollow mesoporous structured Bi2 Se3 . Owing to the lower work function of Au NPs, the photo-induced electrons are easier to transfer and assemble on their surfaces, resulting in the increased separation of the electron-hole pairs with efficient ROS generation. Besides, Bi2 Se3 /Au heterostructures also enhance the photothermal efficiency due to the effective orbital overlaps with accelerated electron migrations according to density functional theory calculations. Moreover, the PLGA-PEG and the doxorubicin (DOX) are introduced for photothermal-triggered drug release in the system. The Bi2 Se3 /Au heterostructures also displays excellent infrared thermal (IRT) and computed tomography (CT) dual-modal imaging property for promising cancer diagnosis. Collectively, Bi2 Se3 /Au@PLGA-PEG-DOX exhibits prominent tumor inhibition effect based on synchronous PTT, PCT and chemotherapy triggered by NIR light for efficient antitumor treatment.

Abstract
AIMS Soil salinization severely inhibits plant growth, leading to a low crop yield. The aim of the current study was to isolate endophytic bacteria with the ability to promote rice growth under saline conditions. METHODS AND RESULTS We isolated eight salt-tolerant endophytic bacteria from rice roots. An isolated strain D1 was selected due to its ability to stimulate rice seed germination in the presence of NaCl, which was identified as Pantoea ananatis D1. It exhibited multiple plant growth-promoting traits including phosphate solubilization, production of indole-3-acetic acid, 1-aminocyclopropane-1-carboxylic acid (ACC) deaminase and siderophore. Inoculation of P. ananatis D1 obviously enhanced the rice root and shoot growth under normal and saline conditions. It also significantly increased the contents of chlorophyll, total soluble protein, and proline in salt-stressed rice seedlings. Moreover P. ananatis D1 could ameliorate the oxidative stress in rice induced by NaCl and Na2 CO3 treatment. The malondialdehyde content and various antioxidant enzyme activities were decreased by P. ananatis D1 inoculation in salt-affected rice. In addition, P. ananatis D1 showed a positive potential for limiting the Na+ accumulation and enhancing the K+ uptake, leading to an increase of 1·2-1·7 fold in K+ /Na+ ratio under saline environment. CONCLUSIONS Pantoea ananatis D1 has the ability to improve the salt tolerance of rice seedlings. SIGNIFICANCE AND IMPACT OF THE STUDY The application of plant growth-promoting bacteria (PGPB) is an eco-friendly strategy to improve plant tolerance towards abiotic stresses. We demonstrated that P. ananatis D1 could be used as an effective halotolerant PGPB to enhance rice growth in different salt-affected soils.

Abstract
In order to achieve better antitumor therapeutic efficacy and inhibit tumor metastasis, a multifunctional nanovaccine based on L-arginine (LA)-loaded black mesoporous titania (BMT) is fabricated. In this system, LA is utilized as the exogenous NO supplementation for gas therapy, and BMT is served as acoustic sensitizer for sonodynamic therapy. The ultrasound (US) as the exogenous stimulus can simultaneously trigger BMT and LA to produce singlet oxygen (1 O2 ) and NO gas at tumor sites, respectively. Interestingly, 1 O2 from US-excited BMT can promote the oxidation of LA to produce more NO. The high concentration of 1 O2 and NO in cancer cell can cause intracellular strong oxidative stress level and DNA double-strand breaks to induce cancer cell apoptosis ultimately. The US-triggered BMT@LA "nanovaccine" combining with immune checkpoint inhibitor PD-L1 antibody (αPD-L1) can induce strong antitumor immune response thus effectively killing primary tumors and further inhibiting metastatic tumors. Hence, BMT@LA-based "nanovaccine" combining with αPD-L1 checkpoint blockade treatment can realize synergetic sonodynamic/gas/immunotherapy with enhanced antitumor therapeutic effects.

Abstract
The past decades have witnessed hyperthermia therapy (HTT) as an emerging strategy against malignant tumors. Nanomaterial-based photothermal therapy (PTT) and magnetic hyperthermia (MHT), as highly effective and noninvasive treatment models, offer advantages over other strategies in the treatment of different types of tumors. However, both PTT and MHT cannot completely cure cancer due to recurrence and distal metastasis. In recent years, cancer immunotherapy has attracted widespread attention owing to its capability to activate the body's own natural defense to identify, attack, and eradicate cancer cells. Significant efforts have been devoted to studying the activated immune responses caused by hyperthermia-ablated tumors. In this article, the synergistic mechanism of HTT in immunotherapy, including immunogenic cell death and reversal of the immunosuppressive tumor microenvironment is discussed. The reports of the combination of HTT or HTT-based multimodal therapy with immunotherapy, including immunoadjuvant exploitation, immune checkpoint blockade therapy, and adoptive cellular immunotherapy are summarized. As highlighted, these strategies could achieve synergistically enhanced therapeutic outcomes against both primary tumors and metastatic lesions, prevent cancer recurrence, and prolong the survival period. Finally, current challenges and prospective developments in HTT-synergized immunotherapy are also reviewed.

Abstract
The emotional ambiguity hypothesis introduced the principle that uncertainty about items' valence determines how emotional content affects memory and other psychological processes. It was formulated to explain why correlations between the perceived valence and arousal of memory items range from weak to unreliable, but it also makes novel predictions. Although data are consistent with those predictions, the hypothesis does not provide a process model of how valence ambiguity causes the valence-arousal relation to fluctuate. We tested 2 such models-a quantitative one, which assumes that increasing ambiguity lowers the reliability of valence judgments, and a categorical/quantitative one, which assumes that increasing ambiguity restricts the range of valence judgments. These models predict different mathematical relations between measures of ambiguity and intensity for valence and other semantic attributes (e.g., arousal, concreteness, familiarity, imagery, meaningfulness). In Experiments 1-3, tests of those predictions favored the categorical/quantitative model-showing that ambiguity is an inverted-U function for valence and other attributes. Experiments 4 and 5 were designed to investigate whether the memory effects of valence ambiguity are similar to the known effects of valence intensity. In both experiments, recall improved when ambiguity was increased, as well as when intensity was increased. A mathematical model revealed that increases in ambiguity produced large increases in items' familiarity, whereas increases in intensity produced smaller increases in both recollection and familiarity.

Abstract
BACKGROUND Several studies have indicated that older adults with cognitive impairment have a poorer lifestyle than their healthy peers including lower 25-hydroxy-vitamin D levels (25OHD). AIM To investigate the associations between lifestyle and 25OHD depending on cognitive status among old adults. METHODS Community-dwelling old adults (65-96 years) participated in this cross-sectional study based on the Age-Gene/Environment-Susceptibility-Reykjavik-Study. The analytical sample included 5162 subjects who were stratified by cognitive status, i.e., dementia (n = 307), mild cognitive impairment (MCI, n = 492), and normal cognitive status (NCS, n = 4363). Lifestyle variables were assessed and 25OHD was measured. The associations between lifestyle and 25OHD were calculated using linear models correcting for potential confounders. RESULTS According to linear regression models, 25OHD was significantly lower in older people with dementia (53.8 ± 19.6 nmol/L) than in NCS participants (57.6 ± 17.7 nmol/L). Cod liver oil (7.1-9.2 nmol/L, P < 0.001) and dietary supplements (4.4-11.5 nmol/L, P < 0.001) were associated with higher 25OHD in all three groups. However, physical activity ≥ 3 h/week (2.82 nmol/L, P < 0.001), BMI < 30 kg/m2 (5.2 nmol/L, P < 0.001), non-smoking (4.8 nmol/L, P < 0.001), alcohol consumption (2.7 nmol/L, P < 0.001), and fatty fish consumption ≥ 3x/week (2.6 nmol/L, P < 0.001) were related to higher 25OHD in NCS only, but not in participants with dementia or MCI. DISCUSSION Older people living in Iceland with dementia are at higher risk for 25OHD deficiency when compared to healthy individuals. Physical activity reported among participants with dementia, and MCI is low and is not significantly associated with 25OHD. CONCLUSIONS Lifestyle factors among NCS participants are associated with 25OHD levels. Importantly, healthy lifestyle should be promoted among individuals with MCI and dementia.

Abstract
Rational design of tumor microenvironment (TME)-activated nanocomposites provides an innovative strategy to construct responsive oncotherapy. In colorectal cancer (CRC), the specific physiological features are the overexpressed endogenous H2 S and slightly acidic microenvironment. Here, a core-shell Cu2 O@CaCO3 nanostructure for CRC "turn-on" therapy is reported. With CaCO3 responsive to pH decomposition and Cu2 O responsive to H2 S sulfuration, Cu2 O@CaCO3 can be triggered "on" into the therapeutic mode by the colorectal TME. When the CaCO3 shell decomposes and releases calcium in acidic colorectal TME, the loss of protection from the CaCO3 shell exposes the Cu2 O core to be sulfuretted by H2 S to form metabolizable Cu31 S16 nanocrystals that gain remarkably strong near-infrared absorption. After modifying hyaluronic acid, Cu2 O@CaCO3 can achieve synergistic CRC-targeted and TME-triggered photothermal/photodynamic/chemodynamic/calcium-overload-mediated therapy. Moreover, it is found that the generation of hyperthermia and oxidative stress from Cu2 O@CaCO3 nanocomposites can efficiently reprogram the macrophages from the M2 phenotype to the M1 phenotype and initiate a vaccine-like immune effect after primary tumor removal, which further induces an immune-favorable TME and intense immune responses for anti-CD47 antibody to simultaneously inhibit CRC distant metastasis and recurrence by immunotherapy.

Abstract
Although synergistic therapy for tumors has displayed significant promise for effective treatment of cancer, developing a simple and effective strategy to build a multi-functional nanoplatform is still a huge challenge. By virtue of the characteristics of tumor microenvironment, such as hypoxia, slight acidity and H2O2 overexpression, Au2Pt-PEG-Ce6 nanoformulation is constructed for collaborative chemodynamic/phototherapy of tumors. Specifically, the Au2Pt nanozymes with multiple functions are synthesized in one step at room temperature. The photosensitizer chlorin e6 (Ce6) is covalently linked to Au2Pt nanozymes for photodynamic therapy (PDT). Interestingly, the Au2Pt nanozymes possess catalase- and peroxidase-like activities simultaneously, which not only can generate O2 for relaxation of tumor hypoxia and enhancement of PDT efficiency but also can produce ∙OH for chemodynamic therapy (CDT). In addition, the high photothermal conversion efficiency (η = 31.5%) of Au2Pt-PEG-Ce6 nanoformulation provides the possibility for photoacoustic (PA) and photothermal (PT) imaging guided photothermal therapy (PTT). Moreover, the presence of high-Z elements (Au and Pt) in Au2Pt-PEG-Ce6 nanoformulation endows it with the ability to act as an X-ray computed tomography (CT) imaging contrast agent. All in all, the Au2Pt-PEG-Ce6 exhibits great potential in multimodal imaging-guided synergistic PTT/PDT/CDT with remarkably tumor specificity and enhanced therapy.

Abstract
We removed a key uncertainty in the Deese/Roediger/McDermott (DRM) illusion. The mean backward associative strength (MBAS) of DRM lists is the best-known predictor of this illusion, but it is confounded with semantic relations between lists and critical distractors. Thus, it is unclear whether associative relations, semantic relations, or both foment the illusion. In Experiment 1, we developed a tool for investigating this question-a normed pool of materials in which subjects rated the gist strength of 120 DRM lists that varied widely in MBAS. This produced a mean gist strength (MGS) statistic for each list, which allowed MGS and MBAS to be manipulated factorially. In Experiment 2, we conducted the first MGS (high vs. low) × MBAS (high vs. low) factorial study of the DRM illusion. To measure how MGS and MBAS affect underlying retrieval processes, we implemented a conjoint recognition design. For raw memory performance, MGS affected both true and false recognition of critical distractors, and it affected both true and false recognition of list words. MBAS did not affect true or false recognition of list words or true recognition of critical distractors. With false recognition of critical distractors, it had a reliable effect in one condition when MGS was low, but it had no effect in another condition. At the level of retrieval processes, increasing MGS increased the familiarity of critical distractors' semantic content, and it also increased the familiarity of list words' semantic content.

Abstract
Despite the widespread applications of manganese oxide nanomaterials (MONs) in biomedicine, the intrinsic immunogenicity of MONs is still unclear. MnOx nanospikes (NSs) as tumor microenvironment (TME)-responsive nanoadjuvants and immunogenic cell death (ICD) drugs are proposed for cancer nanovaccine-based immunotherapy. MnOx NSs with large mesoporous structures show ultrahigh loading efficiencies for ovalbumin and tumor cell fragment. The combination of ICD via chemodynamic therapy and ferroptosis inductions, as well as antigen stimulations, presents a better synergistic immunopotentiation action. Furthermore, the obtained nanovaccines achieve TME-responsive magnetic resonance/photoacoustic dual-mode imaging contrasts, while effectively inhibiting primary/distal tumor growth and tumor metastasis.

Abstract
BACKGROUND This study aimed to determine the impact of preoperative exposure to intravenous contrast for CT and the risk of developing postoperative acute kidney injury (AKI) in patients undergoing major gastrointestinal surgery. METHODS This prospective, multicentre cohort study included adults undergoing gastrointestinal resection, stoma reversal or liver resection. Both elective and emergency procedures were included. Preoperative exposure to intravenous contrast was defined as exposure to contrast administered for the purposes of CT up to 7 days before surgery. The primary endpoint was the rate of AKI within 7 days. Propensity score-matched models were adjusted for patient, disease and operative variables. In a sensitivity analysis, a propensity score-matched model explored the association between preoperative exposure to contrast and AKI in the first 48 h after surgery. RESULTS A total of 5378 patients were included across 173 centres. Overall, 1249 patients (23·2 per cent) received intravenous contrast. The overall rate of AKI within 7 days of surgery was 13·4 per cent (718 of 5378). In the propensity score-matched model, preoperative exposure to contrast was not associated with AKI within 7 days (odds ratio (OR) 0·95, 95 per cent c.i. 0·73 to 1·21; P = 0·669). The sensitivity analysis showed no association between preoperative contrast administration and AKI within 48 h after operation (OR 1·09, 0·84 to 1·41; P = 0·498). CONCLUSION There was no association between preoperative intravenous contrast administered for CT up to 7 days before surgery and postoperative AKI. Risk of contrast-induced nephropathy should not be used as a reason to avoid contrast-enhanced CT.
