This paper then examines an illustrative range of contemporary chemical and life science research and associated activities of concern drawn from case study research on China, India, Iran, Russia, Syria and the United States, and assesses how the CWC and BTWC States Parties have inadequately addressed these threats. We then examine how both the CWC and BTWC Review Conferences failed to address these long-term challenges, and we end by providing a series of recommendations for how both regimes can be strengthened in this area.</p></div>","PeriodicalId":52875,"journal":{"name":"Journal of Biosafety and Biosecurity","volume":"6 2","pages":"Pages 99-112"},"PeriodicalIF":0.0,"publicationDate":"2024-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2588933824000098/pdfft?md5=aa875d726ef0ce2dc9e47193a67fbf86&pid=1-s2.0-S2588933824000098-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140399615","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Likely reasons for the unintentional release of laboratory organisms are shortcomings in the handling of infectious liquid biological waste (LBW) and inadequate inactivation procedures. We developed an analytical approach to investigate the use of chemical inactivation (CI) procedures in Swiss research laboratories by on-site random sampling of presumably inactivated infectious LBW and testing it for the presence of infectious lentiviruses (HIV-1) and adenoviruses (AdV). In addition, standard operating procedures (SOPs) for CI were collected and evaluated, and laboratory-staff knowledge of CI processes was assessed using a questionnaire. Although we found several deficiencies in the technical knowledge and training of laboratory staff on the CI of LBW, as documented by 27 returned questionnaires, no infectious viruses were detected in the eight LBW samples collected. Whilst we acknowledge that the number of LBW samples and SOPs is small, we conclude that CI of LBW containing infectious lentiviruses and adenoviruses does not result in the systematic release of considerable amounts of infectious viruses into the environment from research laboratories in Switzerland.</p></div>","PeriodicalId":52875,"journal":{"name":"Journal of Biosafety and Biosecurity","volume":"6 1","pages":"Pages 16-26"},"PeriodicalIF":0.0,"publicationDate":"2024-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2588933824000049/pdfft?md5=3b90d552352992df0ce804399f533c54&pid=1-s2.0-S2588933824000049-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140069441","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Various actions, such as quarantine, vaccination, and hospitalization, have been implemented by worldwide governments. Given the relatively high cost and strict implementation of vaccination, our focus lies on quarantine and hospitalization. In this paper, we study the monkeypox epidemic involving quarantine and hospitalization through fractional-order mathematical modeling. The proposed model considers six classes of human populations (susceptible, exposed, infected, quarantined, hospitalized, and recovered) and three classes of nonhuman populations (susceptible, exposed, and infected). The basic properties of the model have been investigated, and its equilibrium points have been obtained, namely monkeypox-free, nonhuman-free endemic, and endemic. We have derived the basic reproduction numbers for human-to-human and nonhuman-to-nonhuman transmissions, denoted as <span><math><mrow><msub><mi>R</mi><mrow><mn>0</mn><mi>h</mi></mrow></msub></mrow></math></span> and <span><math><mrow><msub><mi>R</mi><mrow><mn>0</mn><mi>n</mi></mrow></msub></mrow></math></span> respectively.

The rapid development of these biotechnologies has had a wide and profound impact globally, with the majority on the frontier of biosecurity technologies. The global biosecurity situation is currently highly challenging, with the characteristics of internationalization, extremely serious harm, and complex development. The misuse and abuse of biotechnologies are common, which thereby endanger biosecurity. The international community and governments have attached great importance to cutting-edge biotechnologies and are implementing laws and regulations to control and prevent biosecurity-related influences. By tracking the frontier progress of the new technologies generated from gene editing, gene drives, synthetic biology, and related cross-disciplines as applied in the biosecurity field, we analyzed the development trends in biotechnologies and their potential influence. On the one hand, this paper proposes that there is an urgent need for global cooperation to formulate management, control strategies, and measures for cutting-edge technologies in biosecurity to jointly promote their sound development. On the other hand, the international community should jointly shoulder the responsibility for safeguarding biosecurity and restrict the biotechnologies to rational applications within legal and ethical frameworks.

Studies indicate a high proportion of bedaquiline-resistant cases have previously been treated for TB, and often involve strains resistant to quinolones. Regular monitoring of the culture status in patients receiving bedaquiline resistance treatment is advised. Methods such as experimental evolution, protein modeling, genome sequencing, and phenotypic analysis have been instrumental in identifying the mechanisms of bedaquiline resistance. Specifically, variants in the Rv0678 transcriptional repressor of the MmpS5-MmpL5 efflux system are linked to this type of resistance. Bayesian probability estimates show promise in determining the genotypic–phenotypic association for bedaquiline resistance, suggesting potential utility in clinical practice.

Their threat resides in the variety of transmission modes that they possess, along with the wide selection of favorable hosts, such as humans, cattle, and rodents. MBDs are increasingly gaining a reputation as one of the most dangerous threats to public health in recent years. Mosquito numbers have been increasing in recent years as a result of multiple factors such as climate change and deforestation. This situation highlights the urgent need for actions to mitigate mosquito and MBD pathogen distributions. In the Middle East, many outbreaks of MBDs have been reported in the region. However, there are no reports of any endemic episodes of MBDs. The Middle East has faced many challenges over the years; however, the Syrian refugee crisis may be strongly related to the spread of infectious diseases. As mass gatherings and high-density populations are common features in the region, it is possible to understand why MBDs can spread easily. This review summarizes the state of MBDs in the Middle East, highlighting the different types of MBDs that have been reported in the region and discussing how to move forward with controlling their spread and limiting the risks they pose. According to the data reported by the electronic State Parties Self-Assessment Annual Reporting Tool (e-SPAR), the capacity to anticipate MBVs varies among Middle East countries. Therefore, the Middle East is on the frontline in the challenge to control a potential public health crisis. Consequently, the countries of the Middle East should be encouraged to improve their health and research capacities to mitigate the threat posed by MBDs.</p></div>","PeriodicalId":52875,"journal":{"name":"Journal of Biosafety and Biosecurity","volume":"6 1","pages":"Pages 1-12"},"PeriodicalIF":0.0,"publicationDate":"2024-01-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2588933824000013/pdfft?md5=0d46b66e1068695b0413d46469474233&pid=1-s2.0-S2588933824000013-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139487464","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
