Summary: Periodontitis is a common condition that can lead to tooth loss, and its treatment usually involves scaling and root planing. However, recent studies have shown that probiotics and postbiotics may have potential therapeutic benefits in managing periodontitis. More research is needed to fully understand the impact and limitations of these treatments.

Summary: Lactic acid bacteria (LAB) are essential for the production of fermented dairy products and their viability and functionality are critical. A standard protocol has been developed by North Carolina Agriculture and Technical State University for the activation and quality control of LAB strains, resulting in highly functional and viable cultures for fermentation research. This protocol can be recommended for the dairy and food industry to ensure LAB viability and functionality.

Summary: This study investigated the ability of selected commensal and probiotic bacteria to bind different strains of rotavirus (RV) via histo-blood group antigens (HBGAs) and to block RV infection of IPEC-J2 cells. The results showed that certain bacteria expressed HBGAs which correlated with their ability to bind RVs and some bacteria demonstrated the ability to block RV attachment onto host cells.

Summary: This study aimed to explore the importance of specific adult attachments in the working setting and their associations with organizational variables. The results showed that work-specific attachment models differ from romantic attachment models and also vary among themselves. Depending on attachment to colleagues, two attachment orientations (secure and insecure) can be distinguished among working adults. Fostering secure attachment at work may lead to positive outcomes in terms of performance and relationships.

Summary: In this study, novel nanofibers based on apple pectin were fabricated using electrospinning. The nanofibers were characterized for their physiochemical, mechanical, and thermal properties. Under simulated gastrointestinal conditions, the encapsulated probiotics showed a higher survival rate compared to free cells. The PVA/PEC-based nanofibers have good barrier properties and could potentially be used to improve the viability of probiotics and develop functional foods.

Summary: The study evaluated the effect of dietary fibre obtained from pomegranate, tomato, grape, and broccoli by-products on the survival, growth, and metabolism of six probiotic strains. Results indicated that different by-products had varying impacts on probiotic microorganisms, with tomato peel fibre having the most effective protective effect and grape stems promoting the growth of lactic acid bacteria. In addition, all fibres increased the production of short-chain fatty acids in vitro, with broccoli stems and pomegranate peel showing higher stimulation.

Summary: This study uses chloroplast genetic markers to elucidate the Pleistocene history and present-day distribution of southern beech species in New Zealand, showing broadly concordant phylogeographic patterns. The genetic diversity of silver beech is centered in the northern South Island, with unique haplotypes in various regions separated by known 'beech gaps'. In contrast, the subgenus Fuscospora shows significantly less genetic diversity.

Summary: This study investigated the viability and germination of ectomycorrhizal fungi (EMF) spores associated with southern beech forest in New Zealand. Different spore taxa showed varying germination rates and responses to different temperature and light conditions. For storing EMF material as inoculum, it is recommended to dry fruiting bodies at 30 degrees C and prepare fresh spore suspensions in water when needed.

Summary: Nothofagus (southern beech) restoration projects are becoming increasingly important in the southern hemisphere, but current techniques yield mixed results. Providing shelter, controlling weeds, and protecting from herbivores have positive effects on seedling survival and growth, while fertilizer application and other techniques show inconsistent results. Researchers suggest that future research should focus on unexplored techniques such as ectomycorrhizal fungal inoculum to enhance restoration efforts.

Summary: In this study, the subgenus Cortinarius subgenus Myxacium was redefined based on molecular and taxonomic research, with the identification of taxa that belong to the subgenus and those that do not. A new species, Cortinarius vitreopallidus, was described from New Zealand, and the genus Quadrispora was recombined as a section within the subgenus Cortinarius subg. Myxacium.

Summary: The mechanisms of diversification in fungi are not well understood. Ectomycorrhizal symbionts often prefer specific host genera or families, suggesting that host-symbiont selection may drive fungal diversification. However, it is unknown if there are correlated evolutionary patterns between ectomycorrhizal hosts and symbionts, especially in systems dominated by hosts from the same genus.

Summary: A major fungal lineage centered around Cortinarius vibratilis is identified through morphological and molecular phylogenetic analyses, forming a well-supported clade referred to as the new subgenus C. subg. Vibratiles. This subgenus includes four sections and various small clades. Additionally, two new myxacioid sections, C. sect. Microspermi and C. sect. Turcopedes, are proposed.
