Introduction: This in vitro study assessed how shade changes induced by endodontic medicaments affect the transmission of single and multiples wavelengths of infrared light through enamel and dentin.
Methods: Eighteen extracted single-rooted permanent teeth were prepared, removing all extrinsic staining, and cementum. Tooth slices were treated for 4 weeks with UltraCal™ XS, Ledermix™, or were untreated controls.
Biofilms are structured microbial communities that adhere to various abiotic and biotic surfaces, where organisms are encased in an exo-polysaccharide matrix. Organisms within biofilms use various mechanisms that help them resist external challenges, such as antibiotics, rendering them more resistant to drugs. Therefore, researchers have attempted to develop suitable laboratory models to study the physical features of biofilms, their resistance mechanisms against antimicrobial agents, and their gene and protein expression profiles.

- Exercise has been identified as a factor influencing the gut microbiome, but previous findings have been inconsistent, particularly concerning specific sports.
- The study utilizes publicly available data from athlete gut microbiome research to analyze how exercise affects gut bacteria, discovering 76 species linked to exercise and identifying potential novel species through metagenomic assembly of approximately 2,000 genomes.
- The results indicate significant patterns in the microbiome associated with different sports and suggest that using metagenomics can enhance our understanding of the relationship between exercise and gut health, potentially leading to probiotic development.
Objective: A recent randomized trial of a group psychosocial telehealth intervention (STRIDE) improved anxiety, depression, quality of life (QOL), symptom distress, coping, and self-efficacy to manage symptoms related to taking adjuvant endocrine therapy (AET) in women with non-metastatic hormone receptor-positive breast cancer. This study examined whether changes in coping and self-efficacy mediated intervention effects on anxiety, depression, QOL, and symptom distress.
Method: Women (N = 100) were recruited between 10/2019-06/2021 from Massachusetts General Hospital and were randomized to STRIDE or to the medication monitoring control group.
Salter, J, Forsdyke, D, Dawson, Z, Rymer, J, Walsh, L, and Mundy, P. Reliability and sensitivity of using isometric strength and sprint speed measures in adolescent female athletes. J Strength Cond Res XX(X): 000-000, 2024-The aim of this study was to establish the reliability and sensitivity of isometric mid-thigh pull (IMTP) and sprint speed (5 m, 40 m, and maximal sprint speed) in adolescent women, before exploring the stability of this across maturation to provide maturity-specific benchmarks.
