(Elsevier B.V., 2026-09-03) Christine M. El-Maraghy; Ola M. El-Borady; Heba T. Elbalkiny
Antibiotics in wastewater have become a significant environmental concern, contributing to the emergence of antibiotic-resistant microorganisms and posing a growing threat to global public health. This study comparatively evaluated the effectiveness of biosynthesized and chemically synthesized CeO2 nanoparticles (CeO2NPs) for the degradation of azithromycin (AZI), one of the most frequently detected antibiotics in aquatic environments. The biosynthesized CeO2NPs were prepared using fresh Psidium guajava L. leaves. The response surface methodology, using Box–Behnken experimental design was employed to optimize the critical factors influencing the photodegradation of AZI; as initial concentration of AZI, agitation rate, pH, the contact time, the type and amount of CeO2NPs. The biosynthesized CeO2NPs demonstrated a remarkable removal efficiency of 98.6% at pH 7 and contact time of 5 h under lamp irradiation, significantly exceeding that of the chemically synthesized CeO2NPs. Additionally, the greenness profile of the solvents used was evaluated using the Greenness Index Tool and the nanomaterials performance and synthesis sustainability was assessed by the newly introduced Nanomaterials Assessment Tool (NAT). The recyclability and reusability of the biosynthesized nanoparticles were evaluated, demonstrating consistent efficiency and promising potential for water treatment applications. These findings demonstrate the significant potential of the biosynthesized CeO2NPs for mitigating antibiotic pollution, particularly in strategies aimed at combating bacterial resistance, while also promoting sustainable practices in nanotechnology applications.

Background: Local drug delivery systems have emerged as promising adjuncts to non-surgical periodontal therapy (NSPT) by enhancing drug bioavailability within periodontal pockets. This study aimed to formulate and evaluate a ginger essential oil (GEO) nano-emulgel and compare its clinical efficacy with glucosamine sulphate (GS) gel as adjuncts to NSPT. The primary objective of this work was to evaluate the effectiveness of the local application of Ginger essential oil (GEO) nano-emulgel versus Glucosamine sulphate (GS) gel on clinical parameters of periodontitis, including the plaque index (PI), mean sulcus bleeding index (MSBI), clinical attachment level (CAL), and probing depth (PD) in adjunct to non-surgical periodontal therapy. The secondary objective is to detect the effect of both gels on Receptor activator of nuclear factor kappa B ligand (RANKL) levels in the gingival crevicular fluid (GCF). Methods: GEO nano-emulgel and GS gel were formulated and characterized for physicochemical properties, rheology, and in vitro drug release. GEO nano-emulgel was further evaluated for particle size, polydispersity index, zeta potential, and morphology. A randomized controlled clinical trial was conducted on 30 patients with periodontitis allocated to either the GEO nano-emulgel or GS gel group (n = 15 each) following scaling and root surface debridement. Clinical periodontal parameters were assessed at baseline and after 3 months, while GCF RANKL levels were measured at baseline, 1 month, and 3 months using enzyme-linked immunosorbent assay. Results: The optimized GEO nano-emulgel exhibited favorable physicochemical characteristics, sustained diffusion-controlled drug release, and pseudoplastic flow behavior. Both formulations significantly improved plaque index, mean sulcus bleeding index, probing depth, and clinical attachment level after treatment. No significant intergroup differences were observed in clinical parameters. However, GEO nano-emulgel achieved a significantly greater reduction in GCF RANKL levels than GS gel (p = 0.013). Conclusion: GEO nano-emulgel demonstrated promising adjunctive therapeutic potential for periodontitis by improving clinical outcomes and significantly reducing inflammatory RANKL levels compared with GS gel. Larger, long-term clinical trials are warranted to confirm these findings.

This study aimed to find out the effect of wet cupping versus moderate-intensity aerobic exercise on lipid profile and blood sugar in diabetic obese women. Sixty diabetic women took part in this study; their ages ranged from 40 to 60 years, and their Body Mass Index (BMI) ranged from 30 to 34.9 kg/m2. They were randomly allocated into two groups; group A received medication and moderate aerobic exercise three times per week for eight weeks, and group B received medication and wet cupping two times at two months. Triglycerides, cholesterol, LDL cholesterol, and HDL cholesterol were measured before and after eight weeks at the end of the study. The study demonstrated a statistically significant reduction in the triglyceride levels (p<0.01). Total cholesterol (p<0.01) and LDL (p<0.05) levels decreased significantly in both groups. HDL levels increased significantly in Group A (p<0.01), whereas no significant increase was observed in Group B (p>0.05). It was that aerobic exercise was more effective than wet cupping therapy on the lipid profile in diabetic women.
Catalytic Pyrolysis of Copper-Incorporated Nylon Fishing-Net Waste: Thermal Behavior, Evolved-Vapor Analysis, Kinetics, Thermodynamics, and Artificial Neural Networks
(Multidisciplinary Digital Publishing Institute (MDPI), 2026-08-26) Samy Yousef; Justas Eimontas; Nerijus Striūgas; Vilmantė Kudelytė; Deimantė Čepauskienė; Mohammed Ali Abdelnaby
In this research, the catalytic pyrolysis properties, kinetics, thermodynamic characteristics, and composition of the vapor evolved from the thermal decomposition of copper-incorporated nylon fishing net (CuFN) waste were investigated. The analysis was performed on CuFN composed mainly of nylon and copper (3 wt.%) as an anti-corrosion element. A comparative catalytic study was conducted using two types of zeolite catalysts, ZSM-5 (CuFNz) and Y-type (CuFNy). Reaction complexity in the presence of both catalysts was investigated through linear and nonlinear kinetic approaches, along with estimation of the relevant thermodynamic parameters. In addition, a well-trained artificial neural network was used to predict the catalytic thermal decomposition properties of both batches under untested heating conditions. Thermogravimetric results indicated that the catalyst type moderately influenced the decomposition profiles, with CuFNz achieving complete decomposition at 495 °C (44 wt.%), compared to 475 °C (52 wt.%) for CuFNy. Also, the type of catalyst did not affect the functional groups in TG-FTIR, which showed two main peaks at 1712 cm−1 (Carbonyl group) and 2933 cm−1 (C-H stretching band), but the alkyl C-H band was dominant in the case of CuFNy. Meanwhile, gas-chromatography–mass-spectrometry results indicated that caprolactam (88.21%) was a major GC compound in the CuFNz sample and 5-Cyano-1-pentene (70.43%) was dominant in the vapor of the CuFNy sample. However, the presence of the catalyst increases the complexity of the reaction, reflected by higher pyrolytic activation energies of 244.8 kJ/mol (CuFNz) and 296.3 kJ/mol (CuFNy). Moreover, the mysterious catalytic thermal decomposition of CuFN was fully recognized by the optimized ANN algorithm with R = 1. The study demonstrates that catalytic pyrolysis can convert CuFN into valuable products, including caprolactam using a ZSM-5 catalyst and 5-Cyano-1-pentene using a Y-type catalyst, potentially leading to significant environmental and economic benefits.

(Dr. Yashwant Research Labs Pvt. Ltd., 2026) Hajer M. Abdellatif; Amira E. M. Abdelhay; Sara Atef Ibrahim Hasan; Abeer M. Yousef; Engi E. Sarhan; Ahmed Raafat Ahmed Ali; Nehal Refaay; Mohamed Mohamed Mazen; Mai M. Elbanna; Ahmed M. Elshinnawy
Introduction: Guillain–Barré syndrome (GBS) is an acute immune-mediated disorder of the peripheral nervous system that may result in persistent weakness, impaired motor control, sensory disturbances, fatigue, and reduced functional independence. Upper-limb impairment can affect reaching, grasping, manual dexterity, and activities of daily living. Virtual reality (VR)-based rehabilitation provides repetitive, task-oriented practice with interactive feedback and motivational elements. However, evidence regarding VR-based upper-limb rehabilitation in individuals with GBS remains limited. This systematic review aimed to determine the effects of VR-based rehabilitation on upperlimb function, coordination, and manual dexterity in adults with GBS. Methods: A systematic review conducted using predefined eligibility criteria based on the Population, Intervention, Comparator, and Outcome framework. Studies involving adults aged ≥18 years with GBS considered. Eligible interventions included immersive, semi-immersive, or non-immersive VR-based rehabilitation targeting upper-limb function, delivered alone or in combination with conventional rehabilitation. Primary outcomes included upper-limb functional performance, coordination, and manual dexterity. Secondary outcomes included activities of daily living, functional independence, muscle strength, motor function, range of motion, grip strength, quality of life, fatigue, adherence, and adverse events. Two reviewers independently screened the studies and extracted relevant data. Results: Ten studies were included. VR-based rehabilitation showed potential benefits for upper-limb function, coordination, manual dexterity, and related functional outcomes in adults with GBS. However, substantial heterogeneity observed across interventions and outcome measures. Conclusion: VR-based rehabilitation may improve upper-limb and related functional outcomes in adults with GBS. Further high-quality studies needed to confirm its effectiveness and establish optimal rehabilitation protocols.
