Natural enzymes are a class of biological catalysts that can catalyze a specific substrate. Although natural enzymes have catalytic activity, they are susceptible to the influence of external environment such as temperature, and storage requirements are more stringent. Since the first discovery of magnetic FeO nanoparticles with peroxidase-like activity in 2007, the research on nanoenzymes has entered a rapid development stage.

Skin represents an effective barrier against the penetration of external agents into the human body. Nevertheless, recent research has shown that small particles, especially in the nanosized range, can not only penetrate through the skin but also work as vectors to transport active molecules such as contrast agents or drugs. This knowledge has opened new perspectives on nanomedicine and controlled drug delivery.

Background: 1,4-Naphthoquinone compounds have shown pesticidal activity against Aedes aegypti larvae, a key vector of diseases such as dengue and Zika. However, limited knowledge of their structure-activity relationships has hindered their optimization for pesticide development. This study investigates the structure-activity relationships of 1,4-naphthoquinone, particularly 2-hydroxy-1,4-naphthoquinone and its derivatives.

Background: Dynamic Coronary Roadmap (DCR) is a new PCI method that may reduce contrast dose and contrast-associated acute kidney injury (CA-AKI) risk. This paper evaluates DCR-guided PCI versus standard angiography PCI for contrast usage, procedure time, and CA-AKI risk.
Methods: On May 1, 2024, we searched PubMed, Scopus, Embase, Cochrane Library, and clinicaltrials.

Social relationships are central to well-being. A subgroup of afferent nerve fibers, C-tactile (CT) afferents, are primed to respond to affective, socially relevant touch and may mitigate the effects of stress. The endocannabinoid ligand anandamide (AEA) modulates both social reward and stress.
