These resources hold significant value for translational research. We delve into the diverse origins of organoids, the underlying technologies, and their roles in recapitulating human development, disease modeling, as well as their potential applications in the pharmaceutical field.

It is now recognized that measures to address EDI in research can have a positive impact on the value of health research outputs and health outcomes based on this knowledge. EDI strategies, guidelines, and education and training are now embraced by national research funders and local research organizations. However, these initiatives are very broad and not specific to the field of biobanking. We have, therefore, set out to develop and implement a formal research biobank EDI action plan. This article describes the creation of an EDI action plan that provides an intentional approach to identifying and achieving EDI actions and priorities for our research biobank. The plan is framed by the definitions of EDI and an understanding of the topics, issues, and groups within the EDI field. The plan is founded on a set of guiding principles and delineates three pillars of work that align with team, participant, and researcher domains. The plan identifies a set of 31 actions that are categorized by implementation time frames, in order to positively address EDI issues across these pillars. The completion of these actions will help us to mitigate against bias and enrich our biobanking and research services. Ultimately, our goal is to realize more diverse participation in research supported by our biobank. This would support health research to explore and better understand differences in disease biology and the efficacy of medical treatments across all people.</p>","PeriodicalId":55358,"journal":{"name":"Biopreservation and Biobanking","volume":null,"pages":null},"PeriodicalIF":1.6,"publicationDate":"2024-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141472836","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The strategic decisions about strain selection for certain applications or for the biobank culling necessitate a method to support prioritization and selection. Here, we propose an unbiased scoring approach based on objective parameters to assess, categorize, and assign priorities among samples in stock in a microbial biobank. We describe the concept of this ranking tool and its application to identify high-priority strains for whole genome sequencing with two main goals: (i) genomic characterization of quality control, reference, and type strains; (ii) genome mining for the discovery of natural products, bioactive and antimicrobial molecules, with focus on human diseases.

For this purpose, ovarian slices were obtained from abattoired juvenile lambs and randomly distributed to the following groups: fresh, toxicity, vitrified (control), and three treatment groups in two experiments. Vitamin E, vitamin C, or vitamin E + C was added to the vitrification media alone in the first experiment and added to all vitrification, warming, and culture media in the second experiment. Finally, the treated tissues were cultured <i>in vitro</i> for 12 hours. The histological analysis showed that single or combined use of vitamins E and C increases intact preantral follicles in comparison to the control in two experiments (<i>p</i> < 0.05), and simultaneous use of vitamins E and C had a synergistic effect on increasing the percentage of normal preantral follicles in experiment 2 (<i>p</i> < 0.05). Due to the better results in Experiment 2, stromal cell density, antioxidant activity, and molecular evaluation were followed only in this experiment. The vitamin E + C group had higher stromal cell density compared with control group (<i>p</i> < 0.05). Vitamin E strengthened antioxidant capacity compared with the control and vitamin C groups (<i>p</i> < 0.05). This effect was exacerbated when used in combination with vitamin C (<i>p</i> < 0.05). The expression of all evaluated genes (<i>BMP4, BMP15</i>, <i>GDF9</i>, and <i>KITLG</i>) was significantly increased in ovarian tissue treated with vitamin E + C compared with the control group (<i>p</i> < 0.05).
