Background: Research is the scientific basis for the profession of dietetics, as it must be located and applied in evidence-based practice (EBP). EBP is often presented as a foundational skill for research. CEAR - Core, Evidence Application, Research - is a newly proposed model that separates Research and Evidence Application skills into distinct domains, jointly supported by a set of Core skills, thus acknowledging that education and advancement in one domain neither requires nor precipitates education and advancement in the other. The goal was to investigate the content and construct validity of the new CEAR Model.
Methods: A cross-sectional online survey of randomly selected dietitians in the United States was used to collect CEAR domain scores, validated measures of research or EBP skills and self-reported characteristics. Exploratory factor analysis, Cronbach's α and Pearson correlation between various tools and CEAR domains were used to assess validity and reliability. Analysis of variance (ANOVA) and multiple linear regression between CEAR domains and participant characteristics were used to assess convergent and divergent validity.
Results: One hundred and fifty-four responses with a valid CEAR score were received and led to a three-factor solution, supporting the theorised differentiation of research from evidence application skills (content validity). Internal reliability for the CEAR Model overall and for each domain was high. The hypothesised correlations between existing research or EBP measurement tools and the relevant CEAR domains were found (construct validity). Known groups analysis demonstrated the expected differences in CEAR domain scores based on participant characteristics.
Conclusions: The CEAR Model demonstrates preliminary validity and internal reliability. It adds to the current literature by acknowledging the separateness of evidence application skills from research skills.

In Vivo Evidence for the Preventive Role of Vaccinium macrocarpon Aiton in Indomethacin-Induced Gastric Ulcer: Focusing on Antioxidant, Anti-Inflammatory and Anti-Apoptotic Mechanisms.

The present study aimed to unveil the gastroprotective potential of Vaccinium macrocarpon (VM) extract and its mechanism of action against indomethacin (INDO)-induced gastric ulcers in rats. To achieve this goal, rats were pretreated with either omeprazole (20 mg/kg) or VM (100 mg/kg) orally for 14 consecutive days. Gastric tissue samples were collected and various parameters were evaluated to understand the mechanism of VM's action, including the levels of superoxide dismutase, malondialdehyde, glutathione, CAT and transforming growth factor beta (TGF-β), as well as the mRNA expression levels of tumour necrosis factor alpha, interleukin 1 beta, nuclear factor kappa B (NF-κB) and inhibitor kappa B (IκB).

Unlabelled: Quorum sensing (QS) can regulate diverse critical phenotypic responses in (), enabling bacterial adaptation to external environmental fluctuations and optimizing population advantages. While there is emerging evidence of QS's involvement in influencing phage infections, our current understanding remains limited, necessitating further investigation. In this study, we isolated and characterized a novel phage designated as BUCT640 that infected PAO1.

A new strategy is proposed for second-order data fusion based on the simultaneous modeling of two data sets using the multivariate curve resolution-alternating least-squares (MCR-ALS) model, applying a new constraint during the ALS stage, called "Proportionality of Scores". This approach allows for the fusion of data from different sources, without requiring common dimensionality, and enables the application of specific constraints to each data set. This strategy was applied to the determination of five pharmaceutical contaminants (naproxen, danofloxacin, ofloxacin, sarafloxacin, and enoxacin) in environmental water samples, by fusing two sets of excitation-emission fluorescence matrices, measured before and after photochemical derivatization.

Understanding the behavior of high-entropy carbides (HECs) under oxygen-containing environments is of particular importance for their promising applications in structural components, catalysis, and energy-related fields. Herein, the structural evolution of (Ta, Ti, Cr, Nb)C (HEC-1) nanoparticles (NPs) is tracked in situ during the oxidation at the atomic scale by using an open-cell environmental aberration-corrected scanning transmission electron microscope. Three key stages are clearly discerned during the oxidation of HEC-1 NPs at the atomic level below 900 °C: i) increased amorphization of HEC-1 NPs from 300 to 500 °C due to the energetically favorable formation of carbon vacancies and substitution of carbon with oxygen atoms; ii) nucleation and subsequent growth of locally ordered nanocluster intermediates within the generated amorphous oxides from 500 to 800 °C; and iii) final one-step crystallization of non-equimolar MeO and MeO (Me = metallic elements, Ta, Ti, Cr, and Nb) high-entropy oxides above 800 °C, accompanied with the reduction in atomic defects.

Cancer-associated fibroblasts (CAFs) are key components of the tumor microenvironment (TME). Given their various roles in tumor progression and treatment resistance, CAFs are promising therapeutic targets in cancer. The elimination of tumor-promoting CAFs has been investigated in various animal models to determine whether it effectively suppresses tumor growth.
