Summary: This paper introduces an integrated portable centrifugal microfluidic system that automates cell and fluid manipulation for complete blood counting (CBC) analysis at the point-of-care (POC). The system utilizes a specially designed microfluidic disc for cell separation, solution metering and mixing, and cell counting, and is equipped with a custom script for automated quantification of cells. The proposed method shows a strong correlation with the gold standard hematology analyzer for various blood parameters. The portable system offers simplicity, affordability, and low power consumption, making it a potential solution for improving healthcare delivery in resource-limited settings and remote areas.

Summary: This study proposed wearable electrodes for real-time monitoring of leaf capacitance, which showed good flexibility and stability. The capacitance value was found to be positively correlated with leaf moisture content and showed higher value at night compared to daytime. The growth and physiological parameters of the plant were not significantly affected during capacitance monitoring using the wearable electrodes. These results demonstrate the potential of wearable electrodes for real-time and precise monitoring of plant physiological information in the future.

Summary: This study investigates the effect of polydimethyldiallylammonium chloride (PDDA) on the dark fermentation process of sludge and reveals that PDDA inhibits hydrogen production by reducing the activity of key enzymes and enriching other microorganisms, thus impeding the hydrogen production via the acetate pathway. The findings deepen the understanding of the potential effects of PDDA on sludge treatment and provide a theoretical basis for mitigating the negative impacts of quaternary ammonium-based cationic flocculants.

Summary: This research investigated the degradation properties of polyethylene terephthalate (PET) by PET hydrolase (WCCG) in high-temperature composting and its impact on microbial communities. The study found that the addition of WCCG enzyme slowed down the degradation of PET and reduced the abundance of thermophilic bacteria. However, potential PET degrading microbiota, such as Acinetobacter and Bacillus, were enriched in the composters where PET was reduced without WCCG addition. The external introduction of the WCCG enzyme to the compost reacted with PET and inhibited the proliferation of plastic-degrading bacteria, resulting in a 35% degradation of PET. The research suggests that both the WCCG enzyme and the microbiota associated with plastic-degradation have the potential to reduce PET, providing a novel method for mitigating pollution caused by environmental microplastics.

Summary: Interactions between bacterial species in the formation of dual-species biofilms in the food industry are affected by environmental stresses, such as temperature and pH. This study found that the combination of cold and acid stresses significantly increased biofilm formation, and different temperatures resulted in variations in the presence of specific bacterial species and the secretion of extracellular substances. The findings provide valuable insights for addressing mixed biofilms in food processing under diverse stressful conditions.
