Mechanisms of Pesticide Toxicity in Fish: Insights Into the Ameliorative Role of Plant‐Derived Compounds—A Review

open access: yesAquaculture Nutrition, Volume 2025, Issue 1, 2025.
Pesticide contamination in aquatic environments poses severe risks to fish health, causing oxidative stress, immunosuppression, endocrine disruption, and neurotoxicity. These effects result from the accumulation of reactive oxygen species (ROSs), enzyme inhibition, and damage to physiological systems. Plant‐derived compounds and phytochemicals, such as

AM‐301, a barrier‐forming nasal spray, versus saline spray in seasonal allergic rhinitis: A randomized clinical trial

open access: yesAllergy, Volume 79, Issue 7, Page 1858-1867, July 2024.
We compared the efficacy of two nonpharmacological nasal sprays (AM‐301 and saline) in reducing symptoms of allergic rhinitis in a randomized, controlled clinical trial. A statistically significantly larger reduction in average rTNSS, iTNSS, and RQLQ scores was observed in patients treated with AM‐301 compared to saline‐treated patients.

Analysis of the impact of ionospheric models on the positioning altitude of RNSS receivers

open access: yesJournal of Physics: Conference Series
Abstract This article studies the variation of satellite navigation receiver positioning altitude in static scenarios by configuring different ionospheric models in navigation SoC software and combining them with long-term positioning testing on the “SoC+FPGA” architecture platform of satellite navigation receivers.
