However, it also spurred innovative approaches to pandemic management, notably the development of pathogen detection in wastewater. It was successfully demonstrated that wastewater analysis can not only reflect ongoing COVID-19 infections but also serve as an early indicator of disease prevalence within communities. Recognizing the value of longitudinal analyses of various pathogens, we identified the need for wastewater biobanking. This practice allows for the retrospective analysis of samples, offering critical public health insights at the population level. Moreover, the potential to transport and store biobanked samples at ambient temperature or in a dry state could greatly enhance the utility of this technology, especially in resource-limited settings such as low- and middle-income countries. This article also addresses the ethical considerations and public health implications of wastewater-based epidemiology. While this approach holds significant potential beyond pathogen detection, it is essential to evaluate the benefits and potential risks carefully.</p>","PeriodicalId":55358,"journal":{"name":"Biopreservation and Biobanking","volume":" ","pages":""},"PeriodicalIF":1.6,"publicationDate":"2025-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143506035","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}

In response, the prevalence of repositories-often called \"biobanks\" or \"genome resource banks\"-for storing biological materials from threatened species has become more widespread. This research examined trends for the (1) terminology, (2) taxa representation, (3) global distribution, and (4) operational approach of biobanks versus genome resource banks relating to zoos and wildlife. Our literature search results indicate that although genome resource banking literature began earlier in the 1990s, biobanking has seen a surge in publications with over 3.5× more literature for biobanking since 2020. Genome resource bank articles were highly focused on mammals (68%), while biobanking literature focused more on multi-taxonomic overviews and less-studied taxa. Our search parameters found the largest number of wildlife biobanks in Europe (18) and the lowest number in South America (2), though results are likely impacted by the search being completed in English. Additionally, only 28% (7/25) of global biodiversity hotspots contain a wildlife biobank based on our methodology. While not all wildlife biobanking efforts are published or reported, these findings suggest that (1) \"biobank\" will likely be the more widely used term in the future, (2) more biobanking research is needed for non-mammalian taxa, (3) there are geographical gaps in wildlife biobanks, and (4) conservation biobanking programs should focus on storing biospecimens from a wide set of individuals and develop assisted reproductive technologies concomitantly with the goal of maintaining healthy, sustainable populations in the long term.</p>","PeriodicalId":55358,"journal":{"name":"Biopreservation and Biobanking","volume":" ","pages":""},"PeriodicalIF":1.6,"publicationDate":"2025-02-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143400745","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}

This article addresses this question through an examination of the difficulties that genetic resource collectors and biobankers may encounter in attempting to voluntarily comply with the Nagoya Protocol in Australia, a country that has not ratified the Nagoya Protocol at a federal level. It summarizes the requirements of the Nagoya Protocol, surveys the legal and regulatory situation that currently exists in Australia, and outlines the difficulties and ambiguities encountered by scientists and biobankers in attempting to navigate this system. In the process, it provides an overview of the conceptual and linguistic ambiguities which exist within the framework of the Nagoya Protocol. It argues that consensus models such as voluntary guidelines may be useful for addressing some of these ambiguities and practical challenges, but more fundamental issues will likely require legislative intervention.</p>","PeriodicalId":55358,"journal":{"name":"Biopreservation and Biobanking","volume":"23 1","pages":"23-30"},"PeriodicalIF":1.6,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143494622","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}

While most brain research is carried out using animal models, many neurological diseases are uniquely human. Greater availability of human postmortem brain tissue from diseased individuals and controls would therefore improve the development of treatments for neurological and neuropsychiatric diseases. Globally, organ donation for medical research is dwarfed by organ donation for transplantation. In 2021, 36% of Australians were registered organ donors for transplantation, with public \"in-principle\" support even higher, at 76%. In contrast, there are little data on Australian or international brain donation rates for research. A 30-item online survey was conducted to ascertain knowledge of, and attitudes toward, brain donation in Australia. Of the respondents, 12/237 (5%) were current brain donors and excluded from further analysis. Of the remaining 225, 75% were registered organ donors for transplant. The vast majority (<i>n</i> = 189/225, 84%) of respondents supported or strongly supported the principle of brain donation. However, of those registered for transplantation or whole-body donors, 93/170 (55%) were not aware that brain donation was possible, while 50%, alternatively or also, thought that registering as an organ donor for transplantation rendered them a brain donor by default. Only 9/225 (4%) respondents indicated that they would definitely not donate their brain in the future, while 27 remained unsure. There is prominent public support for brain donation in Australia, with 84% of respondents willing to donate their brain. Yet, the extent of public misconceptions on brain donation for research suggests the need for further education on all types of organ donation, so individuals may make informed decisions.</p>","PeriodicalId":55358,"journal":{"name":"Biopreservation and Biobanking","volume":" ","pages":"31-38"},"PeriodicalIF":1.6,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140066277","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}

These were then compared with the total investment in VCB infrastructure since inception (2006-2022) to determine the return on investment (ROI). A time lag of 40 years was incorporated, recognizing the delay from investment to impact in scientific research. Health gains were therefore measured for the years 2046-2066, with a 3% discount rate applied. Health gains were measured in terms of disability-adjusted life years (DALYs) attributable to VCB-associated research, with monetary cost assigned via the standardized value of a statistical life year (AU$227,000). The age-standardized DALY rate attributable to cancer was modeled for two standpoints (1) extrapolating the current decreasing trajectory and (2) assuming nil future improvement from current rates, with 33% of the difference attributed to scientific innovation. The proportion of the aggregate health gain attributable to VCB-supported research was estimated from the number of VCB-credited scientific publications as a proportion of total oncology publications over the same period. <b><i>Results:</i></b> The AU$32,628,016 of public funding invested in VCB activities over the years 2006-2022 is projected to generate AU$84,561,373 in total (discounted) savings.
