Detection and Inhalation Hazard Assessment of Wear Particles Arising From Abrasion of Market‐relevant Graphene Reinforced Composites

Small, EarlyView.
Abrasion of few‐layer graphene (FLG)–epoxy composites generated respirable particles in which FLG remained fully embedded, as confirmed by correlative HR‑TEM, Raman, and ToF‑SIMS analyses. Advanced lung cell models revealed no cytotoxic or inflammatory responses, and only high‑dose epoxy particles reduced mucociliary clearance.

Mucociliary Clearance Time in Patients with and without Rhinitis [PDF]

, 2014
Background: Rhinitis may be allergic or non allergic. Allergic rhinitis,  intermittent or persistent is the most common type of rhinitis, affecting approximately 20% of the population while nonallergic rhinitis affects 5-10%. While rhinitis is not a life-

Nasal Muco-ciliary transport time alteration: efficacy of 18 B Glycyrrhetinic acid

Multidisciplinary Respiratory Medicine, 2017
Background Mucociliary clearance is the main self-clearing system of the nasal cavity and paranasal sinuses. This is a very important means of non specific defence against continuous organic and inorganic contamination conveyed by air.

Microplastics and the Endocrine–Metabolic Interface: Novel Diagnostic Tools Targeting Thyroid–Adipose Axis

Environmental Toxicology, EarlyView.
ABSTRACT Microplastics (MPs) have been identified as major environmental contaminants that can affect organisms directly and act as carriers of particles and chemical additives, thereby aggravating endocrine networks that coordinate metabolic homeostasis.

PLACE OF MUKOACTIVE THERAPY OF RINOSINUSITIS IN INTERNATIONAL AND RUSSIAN GUIDELINES

Медицинский совет, 2017
Excessive accumulation of mucous secretions in the nasal cavity and paranasal sinuses is key drivers in the pathogenesis  of rhinosinusitis. Mucoactive drugs are actively used to combat this phenomenon.

Mucociliary Clearance in Bronchiectasis

An International Journal Clinical Rhinology, 2016
ABSTRACT Bronchiectasis is a chronic lung disease, defined pathologically as irreversible dilatation of the bronchi. There is ineffective clearance of pulmonary secretions because of damage to the cilia. The nasal mucociliary clearance was studied using the saccharine method in 75 patients of bronchiectasis and the results were compared with those of ...

Establishment of a Human Cell‐Based In Vitro Test System for Investigating and Evaluating Cytotoxic and Immunomodulatory Effects of Indoor Mold

Environmental Toxicology, EarlyView.
ABSTRACT Mold growth in damp indoor environments is a widespread problem associated with respiratory health effects, though causal mechanisms remain incompletely understood. We established a human cell‐based in vitro test system using bronchial epithelial cells (NuLi‐1) and macrophages (THP‐1) to assess inhalation toxicity and immunomodulatory effects ...
