Article Abstract

Purpose: The increasing use of nanomaterials in academic and industrial environments has raised concerns about the potential effects of these materials on human and the environment. Researches have shown that occupational exposure to nanomaterials can affect employees' health. Many companies are active in the field of nanotechnology in Iran. Therefore, this study was designed and conducted to investigate the relationship between the symptoms of these companies' employees and exposure to nanomaterials.

Methods: The study was conducted among employees of 52 nanotechnology companies in Tehran. For this study, the employees of these companies were categorized in two groups: "exposed" and "non-exposed" to nanomaterials. Data collection tools included the NanoTool method form and a nonspecific symptom questionnaire designed and validated by a team of 19 experts in various fields. Finally, data were analyzed using SPSS.22 software.

Results: The results showed that the frequency of cutaneous (such as roughness, itching and redness), respiratory (such as cough, sneezing, and burning throat) and ocular (such as burning, itching and redness) symptoms were higher among the exposed workers to nanomaterials. Examination of the correlation between these symptoms in the two studied groups showed that symptoms with high frequency have a significant relationship with exposure to nanomaterials.

Conclusions: Given the high prevalence of some symptoms among the employees of the studied companies and their association with exposure to nanomaterials, it seems necessary to take control measures to reduce the exposure of employees to nanomaterials and consequently reduce the Investigated symptoms.

Background: Due to the complex structure and variable microenvironment in the progression of bladder cancer, the efficacy of traditional treatment methods such as surgery and chemotherapy is limited. Tumor residual, recurrence and metastasis are still difficult to treat. The integration of diagnosis and treatment based on nanoparticles can offer the potential for precise tumor localization and real-time therapeutic monitoring.

Silicon dioxide nanoparticles (SiO NPs) are a novel material with a wide range of applications whose cumulative effects in the body pose certain health risks. The types of gastric injuries caused by different-sized SiO NPs and their mechanisms, however, remain unclear. Based on this, we established a mouse subchronic exposure model (10 mg/kg/d, 21 consecutive days of tube-feeding) with different SiO NP sizes (50, 300, and 1000 nm) in conjunction with in vitro MC9 and BMMCs models (160 μg/mL exposure for 24 h) to explore the gastric injury mechanisms.

Amino acids are natural organic biomolecules with higher biocompatibility and are crucial for life reactions. Biomolecule-dependent functionality of metallic nanoparticles can tailor them with more effectiveness and biocompatibility. This study was designed to assess the histopathological aspect of gold nanoconjugates (AuNCs) exposure for antioxidant potential in albino mice (Mus Musculus).

Acidochromic fluorescent membranes have garnered significant research interest owing to their potential in real-time environmental monitoring and smart sensing applications. However, the rational design of membranes to optimize their structure-property interplay for enhanced acidochromic performance remains further explored. Herein, we prepared various stimulus-responsive micro/nanofibrous membranes using electrospinning technology by incorporating a fluorescent small molecule (TPECNPy-2) with thermoplastic polyurethane (TPU) to obtain specific properties.

Synaptic plasticity is fundamental for cognitive development and brain function. Aluminium nanoparticles (AlNPs), widely used in industrial and consumer products, pose potential neurotoxic risks, particularly during early neurodevelopment. However, their effects on synaptic plasticity and cognitive outcomes remain poorly understood.
