Article Synopsis
- Polyphenol oxidase (PPO) is responsible for the browning of fruits and vegetables, making it important to find ways to inhibit its activity effectively.
- The study explores the use of mesoporous silica nanoparticles (MSNs) and multiwalled carbon nanotubes (MWCNTs) as safe and stable materials to develop efficient PPO inhibitors.
- Modifying MSNs with dodecyl trimethylammonium bromide (DTAB) significantly inhibits PPO activity, while MWCNTs modified with sodium dodecyl sulfate (SDS) can nearly completely inactivate PPO, though combined modifications show limited effects.
Article Synopsis
- Cinnamomum cassia, a subtropical plant used for food and medicine, has had its suitable habitats affected by climate change, which may impact the effectiveness of herbal remedies.
- The study highlights that key environmental factors like precipitation, temperature, and soil affect the distribution of C. cassia, with optimal habitats currently found mainly in southern China, but likely shifting northward by the 2090s.
- Analytical methods like HPLC and FTIR can help differentiate the quality of C. cassia from various habitats, revealing that higher-quality plants contain more trans-cinnamaldehyde in more suitable environments.
Aqueous two-phase systems (ATPS) are considered a new type of green separation system, but their low selectivity to target molecules limits their practical application. In this study, we used surfactant@MWCNT as an adjuvant to improve the selectivity of PEG/(NH)SO ATPS. The surfactants used include Triton X-100 (TX-100), Tween 80, sodium dodecyl sulfate (SDS), sodium dodecyl benzenesulfonate (SDBS), and bis(2-ethylhexyl)sulfosuccinate sodium salt (AOT).

Unlike the adjuvants used so far, calixarenes can bind ions and molecules multiple noncovalent interactions. In the present study, a water-soluble calixarene, -sulfonatocalix[4]arene (SC[4]), was used for the first time as the adjuvant to improve the performance of the PEG 600/(NH)SO ATPS through multiple interactions.

Background: Acute lung injury (ALI) is a complex disease with a high mortality. Src homology 2 (SH2)-containing protein tyrosine phosphatase 2 (SHP2) is a protein tyrosine phosphatase that participates in pathogenesis of multiple diseases. Nevertheless, the role of SHP2 in ALI remains unknown.

Improving the mental health of the elderly has become an important strategic goal of healthy aging, among which employment is regarded as an essential factor for the mental health of the elderly. This study adopted ordinary least squares, ordered logit, propensity score matching (PSM), and KHB mediation analysis to examine the influence and mechanism of employment on mental health in older Chinese adults using data from the China Health and Retirement Longitudinal Survey of 2018. The study found that employment positively impacts older adults' mental health in China.
