Genotoxicity of nitroso compounds and sodium dichromate in a model combining organ cultures of human nasal epithelia and the comet assay [PDF]

, 2001
Genotoxic effects of xenobiotics are a possible step in tumor initiation in the mucosa of the upper aerodigestive tract. Using the comet assay, detecting genotoxicity in human tissue has been restricted to single incubations in vitro, but in vivo most ...

B Cell Mobilization, Dissemination, Fine Tuning of Local Antigen Specificity and Isotype Selection in Asthma

Frontiers in Immunology, 2021
In order to better understand how the immune system interacts with environmental triggers to produce organ-specific disease, we here address the hypothesis that B and plasma cells are free to migrate through the mucosal surfaces of the upper and lower ...

Paraneoplastic Pemphigus Involving the Respiratory and Gastrointestinal Mucosae [PDF]

Case Reports in Pathology, 2020
Paraneoplastic pemphigus (PNP), an autoimmune mucocutaneous disorder involving the oral and bronchial mucosae, is a rare complication of hematologic malignancy. Serologically, serum autoantibodies against varied desmosome-related proteins are of notice. PNP is often lethal due to bronchiolitis obliterans and opportunistic infection.

Pseudomonas aeruginosa adhesion to normal and injured respiratory mucosa

Memorias do Instituto Oswaldo Cruz, 1992
Human nasal polyps outgrowth culture were used to study the adhesion of Pseudomonas aeruginosa to respiratory cells. By transmission electron microscopy, bacteria associated with ciliated cells were identified trapped at the extremities of cilia, usually

Oral Mucosa as a Potential Site for Diagnosis and Treatment of Allergic and Autoimmune Diseases

Foods, 2021
Most prevalent food allergies during early childhood are caused by foods with a high allergenic protein content, such as milk, egg, nuts, or fish. In older subjects, some respiratory allergies progressively lead to food-induced allergic reactions, which ...

Effects of Cigarette Smoke on the Nasal Respiratory and Olfactory Mucosa in Allergic Rhinitis Mice

Frontiers in Neuroscience, 2020
ObjectiveCigarette smoke (CS) exposure reportedly enhances allergic airway inflammation. However, some studies have shown an association between current cigarette smoke exposure and a low risk for allergic rhinitis.

Histochemical and lectinhistochemical studies on nasal mucosa of pigs with or without respiratory diseases [PDF]

, 2022
Histochemical and lectinhistochemical examinations were carried out on nasal mucosa of pigs with or without respiratory diseases. As the results, both acid and neutral mucins coexisted in nasal mucosa of normal pigs while acid sialomucins were mainly ...

Comparative characteristics of the nasal mucosa microflora at different level of allergic inflammation in the respiratory tract

Инфекция и иммунитет, 2022
In the modern world, allergic respiratory diseases hold a huge place among all chronic diseases. The annual increase in the prevalence of allergic rhinitis and bronchial asthma among the global population makes relevant studies underlying their ...
