Smoking cessation programs might benefit from tailoring messages to individual differences in regulatory focus (see Higgins, 1997), but there is little evidence on the stability or convergent validity of regulatory focus measures. In two studies, smokers completed four measures of regulatory focus: (a) Regulatory Focus Questionnaire (RFQ); (b) actual-ideal and actual-ought self-discrepancies; (c) response duration in naming name ideal or ought self-guides; and (d) reaction time for lexical decisions about one's ideal or ought self-guides. Study 1 included a one-month retest. Retest reliability was adequate, but convergent validity was poor. Questionnaire and self-discrepancy measures were unrelated to each other or to the reaction time measures. To facilitate future studies of tailored health behavior change interventions, research is needed to determine whether weak convergent validity resulted from (a) invalidity of some or all of the regulatory focus measures or (b) validity of each for measuring a different aspect of the construct.

Neurobehavioural Exploration of Breath-counting & Breath-awareness in Novice Indian Meditators: A Naturalised Ānāpānasati-based Paradigmatic Approach.
Ann Neurosci
January 2025
National Resource Centre for Value Education in Engineering, Indian Institute of Technology, Delhi, India.
Background: Neural activity and subjective experiences indicate that breath-awareness practices, which focus on mindful observation of breath, promote tranquil calm and thoughtless awareness.
Purpose: This study explores the impact of tristage Ānāpānasati-based breath meditation on electroencephalography (EEG) oscillations and self-reported mindfulness states in novice meditators following a period of effortful cognition.
Methods: Eighty-nine novice meditators (82 males; Mean Age = 24.
Epigenetic regulation of targeted ferroptosis: A new strategy for drug development.

Ferroptosis is a newly discovered form of cell death that is influenced by iron levels and is triggered by cellular metabolism and excessive lipid peroxidation. Epigenetic regulation plays a crucial role in the development and progression of diseases, making it essential to understand these mechanisms in order to identify potential targets for drug development and clinical treatment. The intersection of ferroptosis and epigenetics has opened up new avenues for research in drug development, offering innovative strategies for combating diseases.

Convergent and parallel evolution occur more frequently than previously thought. Here, we focus on the evolutionary adaptations of angiosperms to sub-zero temperatures. We begin by introducing the research history of convergent and parallel evolution, defining all independent similarities as convergent evolution.

January 2025
Department of Oncology, University of Oxford, Oxford, UK.
Background: The clinical translation of positron emission tomography (PET) radiotracers for cancer management presents complex challenges. We have developed consensus-based recommendations for preclinical and clinical assessment of novel and established radiotracers, applied to image different cancer types, to improve the standardisation of translational methodologies and accelerate clinical implementation.
Methods: A consensus process was developed using the RAND/UCLA Appropriateness Method (RAM) to gather insights from a multidisciplinary panel of 38 key stakeholders on the appropriateness of preclinical and clinical methodologies and stakeholder engagement for PET radiotracer translation.

This study explored the evolving landscape of Microphysiological Systems (MPS), with a focus on organoids and organ-on-a-chip (OoC) technologies, which are promising alternatives to animal testing in drug discovery. MPS technology offers in vitro models with high physiological relevance, simulating organ function for pharmacokinetic studies. Organoids composed of 3D cell aggregates and OoCs mimicking in vivo environments based on microfluidic platforms represent the forefront of MPS.
