The emerging severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) presents hazards to researchers and other laboratory personnel in research settings where the live virus is stored and handled. The Biosafety Level-3 (BSL-3) Core Facility (CF) at Yong Loo Lin School of Medicine in National University of Singapore (NUS Medicine) has implemented a biorisk management (BRM) system to ensure that biorisk to employees, the public, or the environment are consistently minimized to an acceptable level while working with SARS-CoV-2. This chapter summarizes how a BRM system can be implemented in academic institutions based on international standards in the context of existing local legislations/regulations and institutional policies/guidelines to minimize the risk of laboratory-acquired infections and deliberate misuse of the newly emerged virus, SARS-CoV-2 in BSL-3 laboratories. The BRM programs prioritize performing risk assessments prior to implementation of work processes and reassessing the risk portfolio of the facilities from time to time, determining root causes and prevention of recurrences. Focusing on awareness-raising and educating the laboratory users in biosafety and biosecurity, and identifying opportunities for improvement are the other key factors for a sustainable and successful BRM system in the NUS Medicine BSL-3 CF.

Respiratory syncytial virus (RSV) causes symptoms similar to a mild cold for adults, but in case of infants, it causes bronchitis and/or pneumonia, and in some cases, mortality. Mucosal immunity within the respiratory tract includes tissue-resident memory T (T) cells and tissue-resident memory B (B) cells, which provides rapid and efficient protection against RSV re-infection. Therefore, vaccine strategies should aim to generate mucosal immune responses.

Purpose: Breast cancer (BC) brain metastasis (BrM) remains a significant clinical problem. Mucins have been implicated in metastasis; however, if they are also involved in BCBrM remains unknown. We queried BrM patient databases and found Mucin 5AC (MUC5AC) to be upregulated and therefore sought to define the role of MUC5AC in BCBrM.

Rapid and accurate diagnosis of sepsis is of paramount importance to reduce associated morbidity and mortality. The Qvella FAST System is a new instrument that concentrates and purifies bacteria from positive-flagged blood culture bottles (PFBCBs) to produce a "liquid" colony comparable to a subcultured colony in less than 40 min for rapid ID and calibrated antibiotic susceptibility testing (AST). In this study, we evaluated performances of the FAST System workflow and our rapid routine manual workflow (bacterial pellet obtained after lysis, cleaning, washing, and centrifugation for ID; AST by disc diffusion by direct inoculation after dilution) by comparison to the reference method based on 24-h bacterial subcultures.

The SWI/SNF (SWItch/Sucrose Non-Fermentable) chromatin remodeling complex is involved in various aspects of plant development and stress responses. Here, we investigated the role of BRM (BRAHMA), a core catalytic subunit of the SWI/SNF complex, in Arabidopsis thaliana seed biology. brm-3 seeds exhibited enlarged size, reduced yield, increased longevity, and enhanced secondary dormancy, but did not show changes in primary dormancy or salt tolerance.
