Article Abstract
Improvements in the biological control of agricultural pests require improvements in the phenotyping methods used by practitioners to select efficient biological control agent (BCA) populations in industrial rearing or field conditions. Consistent inter-individual variations in behaviour (i.e. animal personality) probably affect BCA efficiency, but have never been taken into account in the development of phenotyping methods, despite having characteristics useful for phenotyping: repeatable (by definition), often heritable, etc. We developed a video-tracking method targeting animal personality traits and evaluated the feasibility of its use for genetic improvement in the BCA , by phenotyping 1,049 individuals from 24 isogenic lines. We found consistent individual variations in boldness, activity and exploration. Personality differences between the 24 isogenic lines suggested a genetic origin of the variations in activity and exploration (broad-sense heritability estimates of 0.06 to 0.11) and revealed a trade-off between exploration and fecundity.

Multi-omics and experimental validation reveal the mechanism of DanxiaTiaoban decoction in treating atherosclerosis.
Phytomedicine
August 2025
Cardiology Department, Affiliated Hospital of Jiangxi University of Chinese Medicine, Nanchang, China. Electronic address:
Background: Atherosclerosis (AS) is a leading risk factor for cardiovascular diseases globally, characterised by the accumulation of lipids and cholesterol in arterial walls, causing vascular narrowing and sclerosis along with chronic inflammation; this leads to increased risk of heart disease and stroke, significantly impacting patients' health. Danxia Tiaoban Decoction (DXTB), a traditional Chinese medicine (TCM) formula, has demonstrated positive clinical effects in treating AS; however, its mechanisms of action remain unclear.
Objective: To explore the potential mechanisms of action of DXTB in treating AS through multi-omics integration and experimental validation.
Decisional Conflict of Proxies in the Thrombolysis Decision-Making Process for Acute Ischaemic Stroke Patients.
Int J Nurs Pract
October 2025
First Affiliated Hospital of Zhengzhou University, Zhengzhou, Henan, China.
Background: Despite being efficacious for acute ischemic stroke, treatment with thrombolysis is often delayed because of the inaccessibility of informed consent from patient proxies. Decisional conflict could be an important contributor to this delay; however, its influencing factors remain unknown. This study sought to survey the decisional conflict of proxies for sufferers of acute ischaemic stroke and explore the influencing factors.

Department of BSc (Hons) Dietetics, Metropolitan College, Athens, Greece.
The present study explored associations between the five personality traits (Extraversion, Agreeableness, Conscientiousness, Neuroticism, and Openness) and dietary patterns of apparently healthy individuals. Demographic, anthropometric, dietary, and personality data were obtained from 480 adults, up to 45 years of age, through self-completed questionnaires. Dietary habits were assessed a validated for the population Food Frequency Questionnaire (FFQ), whereas personality was evaluated with the validated Greek version of the 50-item International Personality Item Pool (IPIP).

La Trobe University, Melbourne, Victoria, Australia.
Background: Grit, resilience and a growth mindset are traits that help health professional students respond positively and adapt to the challenges of the clinical learning environment. The aim of this study was to determine if a 5-week education-based intervention can enhance grit, resilience and a growth mindset in physiotherapy students on clinical placement.
Methods: In this single group intervention study, physiotherapy students participated in a 5-week group-based, online educational intervention for 1 h per week during their first clinical placement.

Triatomines are vectors of Trypanosoma cruzi, the causative agent of Chagas disease. Their locomotor activity is influenced by endogenous and exogenous factors, but whether individual behavioral profiles persist across developmental stages remains unclear. This study evaluated non-oriented locomotor activity in Rhodnius prolixus under varying nutritional states (short-fasting, long-fasting, fed), developmental stages (5th instar nymphs and adults), sex (males and females), and light phase (photophase vs.
