Strategies for reducing meat consumption within college and university settings: A systematic review and meta-analysis

IntroductionDespite the considerable public and planetary health benefits associated with reducing the amount of meat consumed in high-income countries, there is a limited empirical understanding of how these voluntary changes in food choice can be effectively facilitated across different settings. While prior reviews have given us broad insights into the varying capacities of behavior change strategies to promote meaningful reductions in meat consumption, none have compared how they perform relative to each other within a uniform dining context.MethodsTo address this gap in the literature, we synthesized the available research on university-implemented meat reduction interventions and examined the variations in the success rates and effect estimates associated with each of the three approaches identified in our systematic review.ResultsFrom our analyses of the 31 studies that met our criteria for inclusion (n = 31), we found that most were successful in reducing the amount of meat consumed within university settings. Moreover, independent of the number of individual strategies being used, multimodal interventions were found to be more reliable and effective in facilitating these changes in food choice than interventions targeting the choice architecture of the retail environment or conscious decision-making processes alone.DiscussionIn addition to demonstrating the overall value of behavior change initiatives in advancing more sustainable dining practices on college and university campuses, this study lends further insights into the merits and mechanics underlying strategically integrated approaches to dietary change. Further investigations exploring the persistence and generalizability of these effects and intervention design principles are needed.Systematic review registrationhttps://doi.org/10.17605/OSF.IO/DXQ5V, identifier: 10.17605/OSF.IO/DXQ5V

Conceptualising adventurous nature sport: A positive psychology perspective

Abstract Research and public policy has long supported links between traditional sports and well-being. However, adventurous nature sport literature has primarily focused on performance issues and deficit models of risk or sensation-seeking. This standpoint is limited by assumptions that participation is: (a) dependent on personality structures; (b) solely motivated by risk-taking and hedonism; (c) only attractive or accessible to a narrow demographic; and (d) widely perceived as dysfunctional or deviant. In contrast, recent research suggests that adventurous nature sports provide unique benefits due to their context. This paper critically assesses the validity of dominant perspectives against emerging literature to illustrate how nature sports can be conceptualised through a positive psychology lens as well-being activities that facilitate both hedonic and eudaimonic outcomes. The significance of this perspective is that nature sports may become an important consideration when designing health and well-being interventions for both people and the planet

Evidence-Based Management of Hand Eczema

Hand eczema is a common skin disease with a wide variation in morphology and a complex etiology based on endogenous and exogenous factors.The diagnosis of hand eczema is based on patient history, exposure assessment, physical examination, and the results of patch testing. Management of hand eczema starts with education of the patient on the etiology of the disease, and the needed changes in behavior regarding skin care and preventive measures, and avoidance of relevant exposure factors. In many cases, medical treatment is needed for successful management of the disease; use of medication can only be successful with proper education and avoidance of relevant exposure

A Novel Conductometric Urea Biosensor with Improved Analytical Characteristic Based on Recombinant Urease Adsorbed on Nanoparticle of Silicalite

Development of a conductometric biosensor for the urea detection has been reported. It was created using a non-typical method of the recombinant urease immobilization via adsorption on nanoporous particles of silicalite. It should be noted that this biosensor has a number of advantages, such as simple and fast performance, the absence of toxic compounds during biosensor preparation, and high reproducibility (RSD = 5.1 %). The linear range of urea determination by using the biosensor was 0.05–15 mM, and a lower limit of urea detection was 20 μM. The bioselective element was found to be stable for 19 days. The characteristics of recombinant urease-based biomembranes, such as dependence of responses on the protein and ion concentrations, were investigated. It is shown that the developed biosensor can be successfully used for the urea analysis during renal dialysis

Parallel stranded duplex DNA.

Three linear 21-nt oligonucleotides (C2, C3, C7) have been synthesized with different sequences of A and T residues. One pairwise combination, (C3, C7), hybridizes to form a conventional antiparallel duplex (aps-C3.C7), whereas the pair C2, C3 forms a duplex (ps-C2.C3) in which the two strands are in a parallel orientation and the A.T base-pairs in a reverse Watson-Crick configuration. The existence of the novel ps helical structure was established from the following criteria: (i) The electrophoretic mobilities of the ps and aps duplexes in native and denaturing polyacrylamide gels are similar. (ii) The ps duplex is not a substrate for T4 DNA ligase. (iii) Salt-dependent thermal transitions are observed for the two duplexes, but the melting temperatures of the ps molecules are 15 degrees C lower. (iv) The ultraviolet absorption and circular dichroism spectra of the ps duplex are indicative of a base-paired structure, but differ systematically from that of the aps helix. (v) Based on fluorescent measurements, the bis-benzimidazole drug BBI-258 shows a lower affinity for the ps compared to the aps duplex, whereas the opposite preference holds for the intercalator ethidium bromide. We conclude from the present study that parallel stranded DNA is a stable conformation which can arise by interaction between two conventional strands with appropriate sequence homology

Identification of sulfate-reducing bacteria using 16S rRNA binding oligonucleotide probes

Fluorescent-dye-conjugated oligonucleotides were used as "phylogenetic" probes to identify sulfate reducing bacteria (SRB) in a photosynthetic biofilm. Two samples of biofilm from a trickling filter in a waste-water treatment plant were incubated for 48 hr's; one in darkness, the other in daylight. Chemical gradients of (02, S2-, and pH) in the biofiIn1s were then measured with microelectrodes prior to rapid freezing and slicing on a cryo-microtome. The vertical slices were stained with three different probes: a sulfate reducing bacterial (inclusive for most species of the 8-group of purple bacteria), a Desulfobacter, and a non-hybridising control probe. A good correlation between the vertical distribution of SRB and the measured 02-profile was found, with the SRB being restricted to the deeper anaerobic layers
