It was found that dimension change of aptamer DNA significantly weakened the mimicking activity of gold nanozyme, which was contrary to previous research. Based on this, a rapid colorimetric method for the detection of low concentrations of mercury in environmental media was fabricated. It was observed that 40 nM Hg causes color changes in solution. The detection limit of absorbance measurements was estimated to be 9.3 × 10 M. The assay was fast and could complete a single test in half an hour. The detection results for real environment samples confirmed the reliability of the colorimetric analysis in practical application. The proposed assay provides an alternative method for real-time monitoring of mercury in the environment. In particular, the charge effect on the affinity of nanozyme consummated the DNA regulation mechanism for the simulated enzyme activity.

Response mechanism of ethanol-tolerant Saccharomyces cerevisiae strain ES-42 to increased ethanol during continuous ethanol fermentation.
Microb Cell Fact
January 2025
College of Architecture and Environment, Sichuan University, Chengdu, 610065, Sichuan, China.
Background: Continuous fermentation offers advantages in improving production efficiency and reducing costs, making it highly competitive for industrial ethanol production. A key requirement for Saccharomyces cerevisiae strains used in this process is their tolerance to high ethanol concentrations, which enables them to adapt to continuous fermentation conditions. To explore how yeast cells respond to varying levels of ethanol stress during fermentation, a two-month continuous fermentation was conducted.

Previous studies showed that the female genital tract microbiome plays a crucial role in regulating the host's immune defense mechanisms. Our previous research has shown that Lactobacillus gasseri LGV03 (L. gasseri LGV03) isolated from cervico-vagina of HPV-cleared women contributes to clearance of HPV infection and beneficially regulate immune response.

BMC Public Health
January 2025
Faculty of Physical Education and Health, Lin yi University, Lin yi, 276006, China.
Objective: Based on the self-determination theory, the three types of autonomy support of parents, teachers and peers as a whole were included in the same research system to explore their effects on exercise adherence of higher vocational college students and their internal mechanisms.
Methods: The study used the exercise autonomy support scale, autonomous motivation scale and exercise adherence scale to construct and test the hypothesised pathways for promoting exercise adherence among students in higher vocational college. Using the data obtained from a survey of 436 higher vocational college students as the unit of analysis, and taking into account the variable of students' self-determined motivation.
