Summary: The COVID-19 pandemic has led to extensive research on the rapid detection of bioaerosols. Nanotechnology-based detection strategies are proposed as alternatives due to issues in bioaerosol enrichment and lead time for molecular diagnostics; however, the practical implementation of such techniques is still unclear due to obstacles regarding research and development efforts and validation investments.

Summary: The study found that PVDC plastic wraps are the best choice for covering elevator buttons, with very low residual bacteria. Door-close and -open buttons were the most frequently touched sites, requiring more accurate and precise disinfection, therefore cleaning intervals of no longer than three hours may be warranted.

Summary: This study aimed to assess the effectiveness of enhanced classroom cleaning and disinfecting protocol on surface biocontamination and its associations with student absence due to illnesses. The results showed that enhanced cleaning resulted in a significantly lower level of biocontamination on desktops, and there was a significant association between ATP levels on classroom desks and the probability of absence due to gastrointestinal illness.

Summary: The investigation revealed issues in the cleaning procedures of milking and suckling equipment on Japanese farms. The cleanliness of manually washed bucket milkers and suckling buckets was found to be lower than that of automated cleaning, possibly due to inadequate cleaning procedures.

Summary: This article proposes the use of bacterial carbonate mineralization treatments as a novel strategy for preserving decayed fossils and palaeontological heritage. It introduces the application of Myxococcus xanthus, a bacterium known for its effectiveness in ornamental stone bioconsolidation. The article also emphasizes the need for careful monitoring of bacterial inoculation to prevent growth of harmful microbiota that can damage the fossil substrate.

Summary: Adenosine triphosphate (ATP) is a crucial indicator of cell viability. Real-time monitoring of extracellular ATP (eATP) release by bacteria using engineered luciferase can provide insights into bacterial physiology and susceptibility to antibiotics. This method offers faster and more sensitive antimicrobial susceptibility testing compared to conventional methods.

Summary: This study reports the latest progress in using tetraphenylethylene (TPE) fluorophores as a tool for detecting intracellular adenosine triphosphate (ATP). Six different ATP probes were synthesized, and probes with dual positive charge sites showed better selectivity and sensitivity. Among them, P2, with a D-π-A structure, 1,4-bis(bromomethyl)benzene linker, and dual positive charge recognition sites, exhibited higher sensitivity and selectivity in ATP detection. This research has important application value in monitoring the fluctuations of mitochondrial ATP levels.

Summary: This study assessed surface cleaning practices in patient rooms using UV marker technology, revealing that 63% of surfaces were appropriately cleaned, with high-touch patient surfaces remaining neglected. UV marker audits can play a key role in revealing deficiencies in cleaning practices and improving awareness.

Summary: This report describes a method for rapidly measuring total adenylate (ATP + ADP + AMP) in marine sediment samples to estimate microbial biomass. The method involves adding boiled MilliQ water to sediments, which increases the detection limit for ATP + ADP + AMP by up to 100-fold. The method allows for the measurement of ATP + ADP + AMP in low-biomass sub-seafloor sediment cores and can be used as an additional biomass proxy.

Summary: The study evaluated the hygienic condition of posthandwashing facilities in public washrooms near food courts and restaurants in shopping malls. Results showed that exit door handles in male washrooms pose a higher risk of cross and re-contamination, highlighting the importance of attention in these areas.

Summary: This study evaluated the feasibility, safety, and efficacy of systemic infusions of ATP in patients with moderate to severe AD and selected the minimum effective dose of infusion. The results showed that ATP infusion therapy is feasible and safe, but larger studies are needed to assess its efficacy in moderate to severe AD.
