Valence, the representation of a stimulus as positive or negative, is fundamental to conceptualizing attitudes and their empirical research. Valence has two potential representations: semantic and affective. The current line of studies investigates the degree to which the congruency effect of the Brief Implicit Association Test (BIAT), often used as an indirect evaluation measure, reflects affective or semantic aspects of valence.

Article Synopsis
  • MET amplification in EGFR-mutant non-small cell lung cancer (NSCLC) is a common resistance to EGFR inhibitors, and combining EGFR and MET inhibitors shows promise but has varied definitions of MET amplification.
  • In a study of 43 patients with MET copy number gain, those who received the combination of EGFR and MET inhibitors had an 82% clinical benefit rate and longer progression-free survival compared to those receiving MET inhibitors alone or standard of care.
  • The findings suggest that true MET amplification drives better outcomes with combination therapy, indicating a need for further research into how different types of MET copy number gain affect treatment response.

A series of four studies systematically investigated the boundary conditions of the shame-concealment/pride-exposure relationship through an experimental paradigm. Experiment 1 developed an experimental procedure to assess the shame/pride-concealment/exposure relationship. Shame and pride were induced by randomly assigning participants to either low or high fictitious IQ score conditions, followed by an assessment of concealment and exposure behaviors.

Valence, the representation of a stimulus in terms of good or bad, plays a central role in models of affect, value-based learning theories, and value-based decision-making models. Previous work used Unconditioned Stimulus (US) to support a theoretical division between two different types of valence representations for a stimulus: the semantic representation of valence, i.e.

Introduction: Patients with advanced, epidermal growth factor receptor (EGFR)-mutated, non-small cell lung cancer (NSCLC) with Exon 20 insertion mutations (Exon20ins) have poor prognoses, exacerbated by a previous lack of specific treatment guidelines and unmet need for targeted therapies. Amivantamab, an EGFR and MET bispecific antibody, demonstrated efficacy and tolerability in patients with advanced EGFR-mutated NSCLC with Exon20ins following platinum-based therapy in CHRYSALIS (NCT02609776; Cohort D+). Since CHRYSALIS was single-arm, individual patient data (IPD)-based adjusted analyses versus similar patients in real-world clinical practice (RWCP) were conducted to generate comparative evidence.

Land management of parks and vegetation complexity can affect arthropod diversity and subsequently alter trophic interactions between predators and their prey. In this study, we examined spiders in five parks with varying management histories and intensities to determine whether certain spider species were associated with particular plants. We also determined whether web architecture influenced spider occurrence.

Article Synopsis
  • Embryonic development relies on precise DNA processes, and mutations in repair genes can cause neurodevelopmental disorders with symptoms like microcephaly and short stature.
  • Researchers identified genetic variants in SLF2 and SMC5 from the RAD18-SLF1/2-SMC5/6 pathway in patients with developmental issues, including abnormal chromosomes and anemia.
  • The new disorder, named Atelís Syndrome, demonstrates heightened replication stress and difficulties with specific DNA structures, emphasizing the crucial role of the SLF2-SMC5/6 pathway in preserving genome stability.

Background And Objectives: Plasma is often transfused to patients with bleeding or requiring invasive procedures and with abnormal tests of coagulation. Chart audits find half of plasma transfusions unnecessary, resulting in avoidable complications and costs. This multicentre electronic audit was conducted to determine the proportion of plasma transfused without an indication and/or at a sub-therapeutic dose.

The current work investigated the potential dissociation between two modes of valence: affective valence (valence of the emotional response) and semantic valence (stored knowledge about the valence of an object/event). A series of six experiments systematically examined the divergent effect of manipulating the amount of perceptual details on affective valence and semantic knowledge about valence. We predicted that affective valence, more than semantic valence, will be affected by manipulating the amount of stimulus perceptual details.

Introduction: Rebiopsies of non-small cell lung cancers (NSCLC) are mainly performed to (i) cover the evolution of potentially amenable resistance mechanisms against a targeted therapy, and (ii) to identify new therapeutic targets which were not detected in the initial diagnostic biopsy. Comprehensive systematic analyses evaluating the value of rebiopsies are missing.

Methods: Clinical databases from two large comprehensive cancer center networks were queried following prespecified criteria to identify prospectively entered NSCLC cases with at least one rebiopsy at disease progression.
