Cells are encapsulated individually within thin and tough shells in a cytocompatible way, by mimicking the structure of bacterial endospores that survive under hostile conditions. The 3D 'cell-in-shell' structures-coined as 'artificial spores'-enable modulation and control over cellular metabolism, such as control of cell division, resistance to external stresses, and surface-functionalizability, providing a useful platform for applications, including cell-based sensors, cell therapy, regenerative medicine, as well as for fundamental studies on cellular metabolism at the single-cell level and cell-to-cell communications. This Concept focuses on chemical approaches to single-cell encapsulation with artificial shells for creating artificial spores, including cross-linked layer-by-layer assembly, bioinspired mineralization, and mussel-inspired polymerization. The current status and future prospects of this emerging field are also discussed.

The aim of this study was to assess the germination and growth of two strains of following the artificial inoculation of six selected hot dishes with spores which were then stored at temperatures of 40, 50, and 60 °C for 0.5, 1.0, 2.

The increasing popularity of sous-vide (SV) cooking necessitates research into the microbiological quality, sensory changes, and shelf life of SV products. Studies show that SV cooking significantly reduces the levels of meat microbiota and pathogens, positively affecting the shelf life and safety of SV products. However, the meat spoilage organism Clostridium estertheticum can survive SV cooking as it can produce heat-tolerant spores.

Background: Radiotherapy is often given with androgen deprivation therapy for prostate cancer which causes a reduction in testosterone levels, which when below castrate levels, can cause the prostate specific antigen (PSA) levels to be artificially low.
Aim: To determine if high-level radiotherapy clinical trials are underestimating biochemical recurrence (BCR) rates due to inadequate measurement of testosterone levels.
Methods: The study plans for clinical trials performed by the Radiation Therapy Oncology Group (RTOG [now NRG]) on clinicaltrials.

This study aimed to clarify the antifungal activity and action mechanism of the lipopeptides from a marine Bacillus amyloliquefaciens HY2-1 against Penicillium digitatum both in vitro and in vivo. Results showed that HY2-1 lipopeptides exerted obvious inhibitions on spore germination and mycelium growth of P. digitatum.
