Review
OBJECTIVES
To review empirical and peer-reviewed scholarly articles incorporating community-based participatory research approaches and examining discourses of how power differentials are interrogated, negotiated, and redressed within the partnerships using scoping review methodology following The Joanna Briggs Institute framework and Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA).
DATA SOURCES
Articles were identified across five online databases: Embase, ERIC, PsycINFO, PubMed, and Web of Science.
REVIEW METHODS
Keywords used in the search strategy were ("Community-Based Participatory Research" OR "Participa-tory Action Research"). Peer-reviewed scholarly articles discussing in-depth power differentials within the partnership published in English between 2010 and 2020 were included.
RESULTS
Findings indicate scholars use critical reflexive qualitative methodologies to recognize and raise relevant questions of power issues between researchers and community stakeholders. Examination of individual biases, assumptions, and exertion of hierarchical top-down power is identified extensively. There is limited analysis on institutional and interdependent power. As a result of raising questions regarding power issues, individual actions to address emerging tensions and conflicts were reported. However, discussions on researchers' efforts to effect institutional and structural changes to redress power imbalances were limited.
CONCLUSIONS
Building strong and equitable participatory action research collaborations between researchers and community stakeholders remains an arena of continuous struggle. This review offers some insights and relevant implications to better address power issues within participatory action research partnerships and inform the work of professionals engaged in the development, implementation, and evaluation of health promotion initiatives and policies.

Review
Schizophrenia is a severe mental illness that significantly impacts the lives of affected individuals and with increasing mortality rates. Early detection and intervention are crucial for improving outcomes but the lack of validated biomarkers poses great challenges in such efforts. The use of magnetic resonance imaging (MRI) in schizophrenia enables the investigation of the disorder's etiological and neuropathological substrates in vivo. After decades of research, promising findings of MRI have been shown to aid in screening high-risk individuals and predicting illness onset, and predicting symptoms and treatment outcomes of schizophrenia. The integration of machine learning and deep learning techniques makes it possible to develop intelligent diagnostic and prognostic tools with extracted or selected imaging features. In this review, we aimed to provide an overview of current progress and prospects in establishing clinical utility of MRI in schizophrenia. We first provided an overview of MRI findings of brain abnormalities that might underpin the symptoms or treatment response process in schizophrenia patients. Then, we summarized the ongoing efforts in the computer-aided utility of MRI in schizophrenia and discussed the gap between MRI research findings and real-world applications. Finally, promising pathways to promote clinical translation were provided. EVIDENCE LEVEL: 2 TECHNICAL EFFICACY: Stage 3.

OBJECTIVE
The study aimed to evaluate the psychometric properties and measurement invariance (MI) of the Chinese version of the cognitive emotion regulation questionnaire-short (CERQ-short) in cancer patients.
METHODS
This cross-sectional study included 505 cancer patients from mainland China. In addition to sociodemographic and clinical characteristics, the CERQ-short and the distress thermometer were included in the study measures.
RESULTS
Item analysis indicated a promising result. And the results of CFA indicated that the CERQ-short demonstrated satisfactory factorial validity in cancer patients. Cronbach's alpha coefficients were between 0.663 and 0.910, while McDonald's omega coefficients were between 0.664 and 0.910. The CERQ-short had sufficient convergent, discriminant and concurrent validity among cancer patients. Lastly, MI supported that the CERQ-short demonstrated strong measurement equivalence across gender, residence and age.
CONCLUSIONS
This study shows that the Chinese version of the CERQ-short has convincing psychometric properties and MI, which supports its use in cancer patients.

Pyridoxamine (PM) is one of the natural vitamins B6 (VB6) and functions as an endogenous inhibitor for the formation of AGEs (advanced glycation end products). The AGEs are implicated in aging, diabetes, and various neuropsychiatric disease, including schizophrenia, Alzheimer's disease, and Parkinson's disease. However, it is unclear whether the absence of PM per se accumulates AGEs in vivo and causes behavioral dysfunctions. To address these points, we raised PM-deficient fruit flies, Drosophila melanogaster, with the sterilized defined medium. Flies reared in a PM-deficient medium accumulated AGEs and reduced lifespan, impaired gustatory response, sleep, courtship behavior, and olfactory learning. These results suggest that PM suppresses AGE accumulation in vivo and is required for regulating innate and empirical behaviors.

Comparative Study
[Verification of Response Uncertainty in Electrometers through Cross-Comparison with a Novel Current Source: A Comparative Study with Guidelines for Electrometers Used in Radiation Therapy Dosimeters].
BACKGROUND
A new quality assurance and control method for electrometers using a new current source, different from the method published in the guidelines for electrometers, has been reported. This current source uses dry batteries and exhibits excellent performance in terms of voltage, temperature, and time characteristics. The electrometer sensitivity coefficient can be calculated by comparing the sensitivity of one electrometer with that of another on the electrometer calibration coefficient that has been calibrated by a calibration laboratory in advance in both methods. The guideline method requires two or more sets of ionization chambers and electrometers in the facility. In contrast, our method does not use ionization chambers; therefore, the sensitivity ratio of the electrometer can be measured in any facility. This study compared the uncertainty of the electrometer sensitivity factor calculated using the new current source method (current method) with that calculated using a linear accelerator (LINAC) and ionization chambers (LINAC method) described in the electrometer guidelines.
METHOD
In this study, we used a current source that we invented previously by Kawaguchi Electric Works in Japan. The sensitivity ratios of the electrometers were measured with three manufacture's electrometers. The electrometer sensitivity factor was calculated by multiplying the electrometer calibration coefficient. The ionization chamber was 30013 (PTW), and the current source was the current obtained from 10 MV TrueBeam X-rays under calibration conditions. The mean value, standard deviation, and coefficient of variation were calculated. The time required to set up the ionization chamber for calculating the sensitivity ratio of the electrometer was also measured. The accuracy was confirmed by calculating the expanded uncertainty of the electrometer sensitivity coefficients.
RESULTS
The LINAC method had a maximum coefficient of variation of 0.072%. The gross time of the LINAC method was approximately 110 min. The current method had a maximum coefficient of variation of 0.0055% and took less than half the time taken by the LINAC method (35 min) because there was no waiting time for the ionization chamber to be set up and the applied voltage to stabilize under calibration conditions. The expanded uncertainties of the electrometer calibration coefficients were 0.36% and 0.36%, respectively.
CONCLUSION
The new cross-comparison method for electrometer sensitivity factors using a current source is more efficient and useful than the linear accelerator method described in the guidelines; furthermore, this method ensured accuracy for quality assurance and control of electrometers.

Clothianidin (CLO), a neonicotinoid that is widely used in forests and agricultural areas, was recently reported to cause toxicity in mammals. Although sensitivity to chemicals varies between sexes and developmental stages, studies that comprehensively evaluate both males and females are limited. Therefore, in this study we utilized murine models to compare the sex-specific differences in behavioral effects following CLO exposure at different developmental stages. We orally administered CLO to male and female mice as a single high-dose solution (80 mg/kg) during the postnatal period (2-week-old), adolescence (6-week-old), or maturity (10-week-old), and subsequently evaluated higher brain function. The behavioral battery test consisted of open field, light/dark transition, and contextual/cued fear conditioning tests conducted at three and seven months of age. After the behavioral test, the brains were dissected and prepared for immunohistochemical staining. We observed behavioral abnormalities in anxiety, spatial memory, and cued memory only in female mice. Moreover, the immunohistochemical analysis showed a reduction in astrocytes within the hippocampus of female mice with behavioral abnormalities. The behavioral abnormalities observed in female CLO-treated mice were consistent with the typical behavioral abnormalities associated with hippocampal astrocyte dysfunction. It is therefore possible that the CLO-induced behavioral abnormalities are at least in part related to a reduction in astrocyte numbers. The results of this study highlight the differences in behavioral effects following CLO exposure between sexes and developmental stages.

Review
Long-term excessive intake of sodium negatively impacts human health. Effective strategies to reduce sodium content in foods include the use of salty and salt taste-enhancing peptides, which can reduce sodium intake without compromising the flavor or salt taste. Salty and salt taste-enhancing peptides naturally exist in various foods and predominantly manifest as short-chain peptides consisting of < 10 amino acids. These peptides are primarily produced through chemical or enzymatic hydrolysis methods, purified, and identified using ultrafiltration + gel filtration chromatography + liquid chromatography-tandem mass spectrometry. This study reviews the latest developments in these purification and identification technologies, and discusses methods to evaluate their effectiveness in saltiness perception. Additionally, the study explores four biological channels potentially involved in saltiness perception (epithelial sodium channel, transient receptor potential vanilloid 1, calcium-sensing receptor (CaSR), and transmembrane channel-like 4 (TMC4)), with the latter three primarily functioning under high sodium levels. Among the channels, salty taste-enhancing peptides, such as γ-glutamyl peptides, may co-activate the CaSR channel with calcium ions to participate in saltiness perception. Salty taste-enhancing peptides with negatively charged amino acid side chains or terminal groups may replace chloride ions and activate the TMC4 channel, contributing to saltiness perception. Finally, the study discusses the feasibility of using these peptides from the perspectives of food material constraints, processing adaptability, multifunctional application, and cross-modal interaction while emphasizing the importance of utilizing computational technology. This review provides a reference for advancing the development and application of salty and salt-enhancing peptides as sodium substitutes in low-sodium food formulations.

Literature has highlighted that the organic attribute has heuristic value for many consumers, representing an overarching signifier of positive characteristics. Nowadays a plethora of alternative systemic approaches side organic production in the aim to improve the overall sustainability of the agrifood sector. Current study, based on blind and informed tasting, measured sustainability information influence on respondents' (n = 162) perceptions of organic and fungus-resistant grape (FRG) white wines. Findings of the within-subject non hypothetical experiment revealed that information has a stronger, positive impact on participants' perception of organic wine (increasing 13 % monetary preferences) compared to FRG wine (+9%). Additionally, attitudinal characteristics driving consumers' preferences towards FRG wine diverge from organic core motivations.

AIMS
This study aims to identify the top unanswered research priorities in the field of knee surgery using consensus-based methodology.
METHODS
Initial research questions were generated using an online survey sent to all 680 members of the British Association for Surgery of the Knee (BASK). Duplicates were removed and a longlist was generated from this scoping exercise by a panel of 13 experts from across the UK who provided oversight of the process. A modified Delphi process was used to refine the questions and determine a final list. To rank the final list of questions, each question was scored between one (low importance) and ten (high importance) in order to produce the final list.
RESULTS
This consensus exercise took place between December 2020 and April 2022. A total of 286 clinicians from the BASK membership provided input for the initial scoping exercise, which generated a list of 105 distinct research questions. Following review and prioritization, a longlist of 51 questions was sent out for two rounds of the Delphi process. A total of 42 clinicians responded to the first round and 24 responded to the second round. A final list of 24 research questions was then ranked by 36 clinicians. The topics included arthroplasty, infection, meniscus, osteotomy, patellofemoral, cartilage, and ligament pathologies. The management of early osteoarthritis was the highest-ranking question.
CONCLUSION
A Delphi exercise involving the BASK membership has identified the future research priorities in knee surgery. This list of questions will allow clinicians, researchers, and funders to collaborate in order to deliver high-quality research in knee surgery and further advance the care provided to patients with knee pathology.
