Though we often "fear the worst", worrying that unexpectedly bad things will happen, there are times when we "hope for the best", imagining that unexpectedly good things will happen, too. The paper explores how the valence of the current situation influences people's imagining of unexpected future events when participants were instructed to think of "something unexpected". In Experiment 1, participants (N = 127) were asked to report unexpected events to everyday scenarios under different instructional conditions (e.g., asked for "good" or "bad" unexpected events), and manifested a strong negativity bias in response to non-valenced instructions (i.e., being asked to "think of the unexpected" with no valence given). They mainly reported quite "predictable" unexpected outcomes that were negative; however, a post-test (N = 31) showed that the scenarios used were predominantly positive. In Experiment 2 (N = 257), when participants were instructed to think of "something unexpected and bizarre", under the same instructional manipulations as Experiment 1, this negativity bias was replicated. In Experiment 3, using a design in which positive/negative materials were matched (verified by a pre-test, N = 60), it was found that when participants (N = 102) were given negative scenarios, they reported more positive events than they do when they are given positive scenarios. Though responding still retained an overwhelming negative bias, this result provided some evidence for a weaker valence-countering strategy; that is, where a negative scenario can lead to positive unexpected events being mentioned, and a positive scenario leads to negative unexpected events being reported. The implications of these results for people's projections of unexpected futures in their everyday lives is discussed.

T cells have been identified as correlates of protection in viral infections. However, the level of vaccine-induced T cells needed and the extent to which they alone can control acute viral infection in humans remain uncertain. Here we conducted a double-blind, randomized controlled trial involving vaccination and challenge in 33 adult human volunteers, using the live-attenuated yellow fever (YF17D) and chimeric Japanese encephalitis-YF17D (JE/YF17D) vaccines.

Objective: The present study aimed to provide a comprehensive evaluation of the postmarketing safety of belimumab based on the Food and Drug Administration Adverse Event Reporting System (FAERS) database.
Methods: Adverse event (AE) reports in the FAERS database from January 2021 to December 2023 were extracted to perform the disproportionality analysis by calculating the reporting OR. The clinical characteristics and onset times of AEs were investigated.

Dorsal closure is a process that occurs during embryogenesis of . During dorsal closure, the amnioserosa (AS), a one-cell thick epithelial tissue that fills the dorsal opening, shrinks as the lateral epidermis sheets converge and eventually merge. During this process, both shape index and aspect ratio of amnioserosa cells increase markedly.

Introduction: In health care, effective communication enhances teamwork and safety by minimizing adverse events. Evidence suggests that ongoing education should include communication skills training, as interprofessional communication relies on tools that facilitate seamless interaction.
Objective: This project aimed to improve communication practices among nurses in a long-term care unit by promoting evidence-based recommendations.

In the event of a nuclear explosion in an urban environment, contaminated persons may be directed to Community Reception Centers (CRC) and/or public shelters. This paper is a companion document to a previous paper that addresses the inhalation hazard to workers at a CRC from resuspension of fallout from the evacuees. To limit the inhalation hazard evacuees must be screened to prevent severely contaminated persons from entering a CRC.
