Iron is essential for the formation, maturation and dispersal of bacterial biofilms, playing a crucial role in the physiological and metabolic functions of bacteria as well as in the regulation of virulence. Limited availability of iron can impair the formation of robust biofilms by altering cellular motility, hydrophobicity and protein composition of the bacterial surface. In this study, the antibiofilm activity of two natural iron chelating agents, kojic acid (5-hydroxy-2-hydroxymethyl-4H-pyran-4-one) and maltol (3-hydroxy-2-methyl-4-pyrone), were investigated against Staphylococcus aureus and Pseudomonas aeruginosa.

We report a case of simultaneous occurrence of MI and systemic embolism caused by a mechanism not reported to date.
Case Summary: A 52-year-old female patient presented with concurrent chest pain, right arm weakness, and dysphasia.
Cells exert forces on each other and their environment, shaping the tissue. The resulting mechanical stresses can be determined experimentally or estimated computationally using stress inference methods. Over the years, mechanical stress inference has become a non-invasive, low-cost computational method for estimating the relative intercellular stresses and intracellular pressures of tissues.

- Sub-daily variations in greenhouse gas (GHG) emissions from urban ponds in Brussels were studied to establish their significance compared to seasonal and inter-pond variations.
- The study measured CO, CH, and NO levels hourly across different seasons, revealing that CO levels followed a day-night cycle, while CH and NO levels fluctuated more erratically.
- It was concluded that inter-pond variability had a greater impact on emissions than seasonal and sub-daily variations, suggesting a need for focused sampling strategies to better understand these emissions in the context of managing urban water systems.
