Article Abstract

In this study the occurrence of visible anisakid larvae in semi-preserved anchovy products sold on the Italian market was investigated. Totally, 107 ready to eat products (33 salted-ripened, 49 in oil and 25 marinated) were sampled. Each sample was digested, then the digested material was observed under natural and UV light. Parasites were counted, collected and microscopically identified to genus level. A representative subset was molecularly identified using the cox2 gene. At least one visible Anisakis sp. larva was found in 54.2% of the total 107 products analysed and totally 1283 dead larvae were collected. Anisakis sp. larvae were found in all the 33 salted products and 1139 (88.8%) larvae were collected, with a range of 1-105 parasites per product. Larval density per gram was 0.13. Anisakis sp. larvae were found in 49.0% of the products in oil and 143 (11.1%) larvae were isolated, with a range of 0-28 and a density of 0.03. Only 1 larva was found in the 25 marinated products (4.0%, density 0.00). A highly significant difference between all the product categories in respect of number of larvae per product, frequency of products contaminated by at least one larva and larval density per gram was found. Within the subset of larvae molecularly analysed (n=122), 92 (75.4%) were identified as A. pegreffii and 30 (24.6%) as A. simplex. This study showed that semi-preserved anchovy products heavily contaminated with Anisakis spp. larvae reach the market. Beyond the negligible risk for anisakidosis, the presence of dead visible parasites may cause immediate rejection in consumers. In addition, the potential risk related to allergic reactions in sensitized individuals needs to be further assessed. In order to avoid commercialization of obviously contaminated products, fresh anchovies' batches intended for the production of such products should be accurately selected by the processing industry applying inspection methods.

Accurate determination of the parameters of each high purity germanium, HPGe detectors ensure the precision of quantitative results obtained from spectrum analysis. This study presents a comprehensive performance evaluation and long-term quality control assessment of a high-purity germanium (HPGe) gamma spectrometry system that has been operational for over 15 years. Key spectrometric measures were recorded, including energy resolution, peak shape ratios, asymmetry, peak-to-Compton ratio, relative efficiency, electronic noise, minimum detectable activity (MDA), and repeatability and reproducibility of the system.

Background: Atherosclerosis, a leading cause of cardiovascular disease (CVD) mortality worldwide, is characterized by dysregulated lipid metabolism and unresolved inflammation. Macrophage-derived foam cell formation and apoptosis contribute to plaque formation and vulnerability. Elevated serum galectin-3 (Gal-3) levels are associated with increased CVD risk, and Gal-3 in plaques is strongly associated with macrophages.

The generation of reactive oxygen species (ROS) through nanozyme-mediated sonocatalytic therapy has demonstrated remarkable therapeutic efficacy in the field of cancer. Nevertheless, it remains a significant challenge for nanozymes with a single catalytic active center to generate sufficient ROS via Fenton or Fenton-like reactions to effectively induce tumor cell death. In order to enhance the catalytic efficacy, we devised and synthesized a multiple active centre and mitochondrial-targeted perovskite nanozyme (NCFP), doped with cobalt (Co) element, and incorporated 4-carboxybutyltriphenylphosphonium bromide (TPP) as a mitochondrial targeting marker for ultrasound (US)-assisted enzyme-like catalytic treatment of tumors.

Ultra-High Zinc Utilization Enabled by MXene Anode for Flexible Dual-Plating Zn-Br Microbatteries.

J Phys Chem Lett

September 2025

College of Materials Science and Engineering, Sichuan University, No. 24 South Section 1, Yihuan Road, Chengdu 610065, P. R. China.

Aqueous zinc-ion microbatteries exhibit promising prospects for wearable devices due to their high safety and cost-effectiveness but face challenges such as low energy density and short cycle life. To address these challenges, a dual-plating flexible Zn-Br microbattery was developed using freestanding MXene films as a zinc metal free anode. The MXene anode retains no redundant Zn, as Zn from the electrolyte undergoes deposition/stripping reactions on its substrate, thereby eliminating the necessity for excess zinc.
