(Press-News.org) Background and objectives
Artemisia argyi H. Lév. & Vaniot essential oil (AAEO) holds significant pharmacological potential, but its application is constrained by hepatotoxicity. This study aimed to investigate the feasibility of reducing AAEO’s toxicity through storage and to evaluate changes in chemical composition, toxicity, and bioactivity.
Methods
Gas chromatography-mass spectrometry was used to analyze compositional changes during storage. Zebrafish acute toxicity tests and the liver-specific transgenic zebrafish model Tg(fabp10:EGFP) were used to assess toxicity. Antimicrobial, analgesic, and antioxidant assays evaluated variations in bioactivity.
Results
Over the 150-day storage period, gas chromatography-mass spectrometry analysis identified 39 components. Zebrafish acute toxicity tests showed that the LD50 of AAEO stored for 0, 30, 60, 90, 120, and 150 days were 0.10 µL·mL−1, 0.10 µL·mL−1, 0.10 µL·mL−1, 0.11 µL·mL−1, 0.13 µL·mL−1, and 0.14 µL·mL−1, respectively, demonstrating a 40% reduction in acute toxicity after 150 days of storage. Using the liver-specific green fluorescent transgenic Tg(fabp10:EGFP) zebrafish model, the inhibition rates of AAEO on hepatic fluorescence intensity were measured at 68.5%, 43.5%, 42.6%, 37.8%, 34.6%, and 31.9% at different time points, confirming reduced hepatotoxicity after storage. Additionally, the antioxidant and analgesic activities of AAEO were significantly enhanced (p < 0.05) after storage, while the antibacterial activity decreased (p < 0.05).
Conclusions
After storage, AAEO significantly reduces hepatotoxicity, with a 40% decrease in acute toxicity after 150 days. Meanwhile, the antioxidant and analgesic activities of AAEO increase, while its antibacterial activity decreases after storage.

The DNA packed inside every human cell contains instructions for life, written in billions of letters of genetic code. Every time a cell divides, the complete code, divided among 46 chromosomes, must be faithfully copied. This staggering task happens over and over with extraordinary precision.
Decades of research have revealed how dozens of proteins work together to copy chromosomes reliably. Now, Cold Spring Harbor Laboratory (CSHL) President Bruce Stillman and colleagues have compiled these findings into a comprehensive view of the very first step: a “licensing” ...
In a Perspective, Hany Farid highlights the risk of manipulated and fraudulent images and videos, known as deepfakes, and explores interventions that could mitigate the harms deepfakes can cause. Farid explains that visually discriminating the real from the fake has become increasingly difficult and summarizes his research on digital forensic techniques, used to determine whether images and videos have been manipulated. Farid celebrates the positive uses of generative AI, including helping researchers, democratizing content creation, and, in some cases, literally giving voice ...
Kidney complications in diabetes often progress silently, putting patients at risk of life-threatening outcomes long before any symptoms appear. Identifying individuals with diabetes who are at risk of rapid kidney function decline or early death has challenged doctors for decades, with traditional markers like serum creatinine and urinary albumin falling short of accurately predicting these risks.
Fortunately, a new study that was made available online on July 23, 2025, and published in Volume 16, Issue 4 of the Journal of Cachexia, Sarcopenia and Muscle on August 1, 2025, offers ...
Circulating tumor cells (CTCs) refer to cancer cells that have broken off from a primary tumor. These tumor cells can travel through the blood in the circulatory system and lodge themselves in other organs to cause secondary tumors. Therefore, the detection and subsequent characterization of CTCs from blood can help in the clinical diagnosis and treatment of various cancers. However, the efficient capture of CTCs from blood has been proven to be difficult.

This study presents a high-throughput TR-FRET assay targeting the FAK FAT domain's interaction with paxillin, identifying four novel small-molecule inhibitors with potential applications in cancer and fibrosis therapy. The screening strategy ...
There may be a new artificial intelligence-driven tool to turbocharge scientific discovery: virtual labs.
Modeled after a well-established Stanford School of Medicine research group, the virtual lab is complete with an AI principal investigator and seasoned scientists.
“Good science happens when we have deep, interdisciplinary collaborations where people from different backgrounds work together, and often that’s one of the main bottlenecks and challenging parts of research,” said James Zou, PhD, associate professor of biomedical data science who led a study detailing the development of the virtual lab. “In parallel, we’ve ...
A personalised brain stimulation system powered by artificial intelligence (AI) that can safely enhance concentration from home has been developed by researchers from the University of Surrey, the University of Oxford and Cognitive Neurotechnology. Designed to adapt to individual characteristics, the system could help people improve focus during study, work, or other mentally demanding tasks.
Published in npj Digital Medicine, the study is based on a patented approach that uses non-invasive brain stimulation alongside adaptive AI to maximise its impact. The technology uses transcranial random noise stimulation (tRNS) – a gentle and painless form of electrical ...
Quantum sensing has transformational potential across many areas of technology and science, most prominently biomedical research. The basic premise is to detect and manipulate the spin state of an electron - magnetic properties of electrons that can be used to store quantum information - using light. This capability has previously been limited to highly exotic or expensive materials such as nano-sized diamonds with specific atomic defects.
Now, in the paper published in Nature Chemistry, scientists have reported an organic molecule built from carbon atoms in which its optical properties are ...
Scientists studying a hard-to-treat form of blood cancer called acute myeloid leukemia (AML) have found that a type of treatment — immunotherapy — may help change the environment where cancer cells live, possibly helping the immune system respond more effectively.
