  • 简介:AbstractMucormycosis is a lethal human disease caused by fungi of the order Mucorales. Mucormycosis is caused by fungi mainly belonging to the genera Mucor, Rhizopus, and Lichtheimia, all of which belong to the order Mucorales. The number of individuals with mucormycosis-causing disorders has increased in recent years, hence, leading to the spread of mucormycosis. Throughout the coronavirus disease 2019 (COVID-19) pandemic, numerous cases of mucormycosis in COVID-19-infected patients have been reported worldwide, and the illness is now recognized as COVID-19-associated mucormycosis, with most of the cases being reported from India. Immunocompromised patients such as those with bone marrow sickness and uncontrolled diabetes are at a greater risk of developing mucormycosis. Genes, pathways, and other mechanisms have been studied in Mucorales, demonstrating a direct link between virulence and prospective therapeutic and diagnostic targets. This review discusses several proteins such as high-affinity iron permease (FTR1), calcineurin, spore coat protein (CotH), and ADP-ribosylation factors involved in the pathogenesis of mucormycosis that might prove to be viable target(s) for the development of novel diagnostic and therapeutic methods.

  • 简介:AbstractIn order to effectively implement the Tianjin Biosecurity Guidelines for Codes of Conduct for Scientists, biosecurity awareness-raising and education are essential because if these are not in place scientists will not understand the need for biosecurity codes of conduct. In an effort to assist in the implementation of the guidelines, a small-scale survey was carried out in early 2022 of biosecurity awareness-raising and education projects that have been developed over the last two decades to discover what resources and experience have been accumulated. It is argued that the survey demonstrates that much of what is needed to implement the guidelines effectively has been developed, but that there are specific deficiencies that need to be remedied quickly. In particular, an updated teaching resource covering the core issues related to the Biological and Toxin Weapons Convention (BTWC) and the problem of dual use in scientific research needs to be made widely available and translated into at least the six official United Nations (UN) languages. Additionally, more specialists from the Humanities with expertise in ethics need to become involved in biosecurity awareness-raising and education activities. While advantage should be taken now of the available national, regional and international networks of people involved in related activities, it is suggested that in the longer term cooperation in biosecurity awareness-raising and education will benefit from the development of an equivalent organisation to the International Nuclear Security Education Network (INSEN) organised through the International Atomic Energy Agency (IAEA).
