Honokiol ameliorates reserpine-induced fibromyalgia through antioxidant, anti-inflammatory, neurotrophic, and anti-apoptotic mechanisms

Scientific Reports Suzan A. Khodir, Eman M. Sweed, Hala El-Haroun et al. Jul 17, 2025 DOI: 10.1038/s41598-025-07209-w

Abstract Fibromyalgia (FM) is a chronic condition characterized by widespread musculoskeletal pain, fatigue, psychological disturbances, and sleep issues. Honokiol (HNK) is a bioactive compound known for its medicinal properties. This study evaluated HNK’s effectiveness in alleviating pain, depression, and anxiety in a reserpine-induced FM rat model. Thirty male rats were divided into three groups: control, RES (FM-induced), and RES + HNK. HNK was supplemented to RES + HNK in a dose of 8 mg/kg for 21 days. Behavioral assessments included the open field, elevated plus maze, and forced swim tests, while pain was evaluated using treadmill endurance, tail flick latency, paintbrush, and rotarod tests. Brain homogenates were analyzed for neurotransmitters, antioxidants, pro-inflammatory cytokines, and gene expressions. Histopathological evaluation of spinal cords assessed markers of inflammation and apoptosis. Results showed that HNK administration improved behavior and reduced pain. This was linked to reduced levels of malondialdehyde, tumor necrosis factor-α, and prostaglandin E2, alongside increased superoxide dismutase and interleukin-10. Additionally, HNK downregulated the expression of calcitonin gene-related peptide and the JAK/STAT3 gene. These findings suggest that HNK alleviates FM symptoms through its antioxidant, anti-inflammatory, neuroprotective, and anti-apoptotic properties, indicating its potential as a therapeutic agent for FM.

IWOA-LSTM based intrinsic structural identification of steel fiber concrete

Scientific Reports Ping Li, Jie Feng, Shiwei Duan Jul 17, 2025 DOI: 10.1038/s41598-025-08867-6

Abstract Fracture damage in steel fiber concrete (SFRC) is a developmental process in which deformation and damage are coupled with each other. In order to accurately identify the high-temperature constitutive model taking into account the damage evolution, a high-temperature constitutive identification model using the Improved Whale Algorithm (IWOA) optimised Long Short-Term Memory (LSTM) neural network is presented. Firstly, the Laplace crossover operator strategy, the optimal neighbourhood perturbation strategy, the adaptive weighting strategy and the updating strategy of the variables helix position are introduced to solve the problems of the Whale Optimisation Algorithm (WOA) in relation to its slow convergence rate and its tendency to fall into the locally optimal solution. The supremacy of the IWOA has been demonstrated by comparing IWOA with WOA, Crown Porcupine Optimisation Algorithm (CPO), Butterfly Optimisation Algorithm (BOA) and Grey Wolf Optimisation Algorithm (GWO) in terms of optimisation search. Secondly, based on the experimental data, LSTM model, WOA-LSTM model and IWOA-LSTM model were established, where the MSE of IWOA-LSTM model was improved by 47.66% and 65.60% compared to WOA-LSTM model as well as LSTM model. Finally, the constitutive identification model of SFRC using the IWOA-LSTM model was applied to decouple the damage and plastic strain by the comparative analysis of the measured curves and the prediction curves without the damage, so that the damage and its evolution law of steel fiber concrete at different temperatures (T = 200 °C, T = 400 °C and T = 520 °C) were obtained. The degree of approximation between the IWOA-LSTM model’s prediction and experimental data shows that the trained model has a high learning accuracy and good generalization capability, making it appropriate for use in structural engineering applications.

Harvest time and soil-plant relationship effects on phytochemical constituency and biological activities of psidium guajava L. leaves

Scientific Reports Amal M. El-Feky, Mohamed A. E. AbdelRahman Jul 17, 2025 DOI: 10.1038/s41598-025-11323-0

Abstract Guava (Psidium guajava L.) leaves are deemed promising reservoir of phytoconstituents, with their characteristics potentially influenced by the timing of harvest and the dynamics of soil-plant interactions. The study revealed varying concentrations of minerals and vitamins in guava leaves, predominantly featuring vitamins B and C. Assessment of pigments using HPLC revealed that guava leaves collected in March had higher pigment concentration (461.233 mg/100 g) than that collected in August (447.084 mg/100 g). Quantification of total phenolics in guava leaves collected in March and August resulted in measurements of 435.21 ± 0.17 mgGAE/g and 294.31 ± 0.14 mgGAE/g, respectively. HPLC analysis demonstrated a diverse array of phenolic and flavonoid compounds present in Psidium guajava, with greater abundance and concentration of phenolic and flavonoid compounds in the samples harvested in March compared to those collected in August. For biological evaluation, guava leaves harvested in March demonstrated strong scavenging effect on DPPH and ABTS radicals, and considerable inhibition of carbohydrate-metabolizing enzymes (α-amylase, α-glucosidase, and β-galactosidase) in a dose-dependent manner. Furthermore, the March-collected guava leaves exhibited notable inhibition of COX-2 and 5-LOX enzyme activities, surpassing the effects of leaves collected in August. The study’s outcomes demonstrate richness of phytoconstituents in guava leaves, which underpin various biological functions, particularly during spring relative to the summer. This highlights the importance of the timing of collection in assessing phytochemical properties and their biological implications, highlighting the necessity of considering this aspect when sampling guava leaves.
