Introduction: This study aims to expand on previous literature showing that incidental emotion state priming in a specific domain leads to a higher probability that the primed emotion domain will be activated during a subsequent task.
Methods: To that end, we investigated the influence of happy, fearful, and neutral incidental emotion state priming on subsequent responses to emotionally negative and neutral pictures, measured by the event-related potential (ERP) late positive potential (LPP). New to our study, we examined the influence of affective priming on the LPP response (analyzed separately at early and middle latency ranges) to emotional pictures in both the foveal and extrafoveal presentation locations.
Results: Following both fearful and neutral incidental state priming, both the early and middle LPP latency ranges overwhelmingly differentiated between negative and neutral pictures. Following happy incidental state priming, however, the LPP response failed to differentiate between negative and neutral pictures by the middle LPP latency range (800-1,000 ms). These results suggest that incidental happy states can have a protective effect when viewing aversive stimuli. Additionally, the LPP showed greater sensitivity to negative stimuli when presented extrafoveally compared to foveally.
Conclusions: Overall, our findings suggest that incidental affective state and stimulus location influence emotional processing differentially for emotionally negative and emotionally neutral stimuli.

As one of the earliest identified susceptible animals for the SARS-CoV-2, cats are also the vulnerable hosts for feline coronaviruses, ie feline enteric coronavirus (FECV). Here, to understand the cross-presentation of coronavirus-derived peptides by cat major histocompatibility complex molecule feline leucocyte antigen (FLA) class I, unpredictable natural peptide motifs presented by FLA-K*00701 and FLA-E*00301 were identified through peptide elution and further confirmed by the structural determination of the 2 FLA class I molecules. Based on these precise motifs of FLA class I peptides, the atlas of cross-presenting peptides from different coronaviruses in cats were sketched with 3 hotspots in C-terminal half of ORF1ab protein.

While therapeutic vaccines are a promising strategy for inducing human immunodeficiency virus (HIV) control, HIV vaccines tested to date have offered limited benefit to people living with HIV. The barriers to success may include the use of vaccine platforms and/or immunogens that drive weak or suboptimal immune responses, immune escape and/or immune dysfunction associated with chronic infection despite effective antiretroviral therapy. Combining vaccines with immune modulators in a safe manner may address some of the challenges and thus increase the efficacy of therapeutic HIV vaccines.

Pyroptosis, a form of programmed cell death mediated by the gasdermin family, has emerged as a promising strategy for inducing anti-tumor immunity. However, efficiently inducing pyroptosis in tumor cells remains a significant challenge due to the limited activation of key mediators like caspases in tumor tissues. Herein, a self-priming pyroptosis-inducing agent (MnNZ@OMV) is developed by integrating outer membrane vesicles (OMVs) with manganese dioxide nanozymes (MnNZ) to trigger pyroptosis in tumor cells.

Post-weaning diarrhea (PWD) is associated predominantly with enterotoxigenic (ETEC) and continuously causes significant economic losses to swine producers worldwide. Currently, there are no effective countermeasures against this significant swine disease. Challenges persist in developing vaccines against PWD since ETEC strains produce heterogeneous virulence factors, including F4 (K88) and F18 fimbria and heat-labile toxin (LT), heat-stable toxin type I (STa), heat-stable toxin II (STb), and Shiga toxin type 2e (Stx2e, also causes edema disease).

Plant-plant interactions are often overlooked when assessing carbon (C) cycling in plant community. Limited research exists on how nutrient competition influences soil organic carbon (SOC) dynamics via modifying rhizosphere C turnover. To address this issue, quantitative model of plant-plant interactions was established in three intercropping systems across 4 years.
