: Nasal mucus is the first line defense barrier against various pathogens including allergens. Proteins in nasal mucus maybe used as biomarkers for diagnosis or future therapeutic strategies. Proteomics opens the possibility to investigate whole human proteomes.: We aimed to analyze the existing literature on nasal mucus and nasal secretions proteomic approaches especially in allergic rhinitis. A PubMed/Medline search was conducted entering the following keywords and combinations: "nasal mucus", "nasal lavage fluid," nasal secretions," "nasal swabs," "allergic rhinitis," "proteins," and "proteomics.": The majority of studies focus on single proteins or protein groups mainly using ELISA techniques. Four studies met the criteria using mass spectrometry in the analysis of nasal mucus proteomes in rhinologic diseases. In these studies, 7, 35, 267, and 430 proteins were identified, respectively. These four studies are discussed in this review and put in relation to seven other proteomic studies that focus on nasal lavage fluid and nasal secretions obtained by swabs or filter paper. To put it in a nutshell, proteomics facilitates the investigation of the nasal secretome and its role in healthy and diseased state and as potential biomarkers for new diagnostic or therapeutic approaches.

Autoimmune gastritis (AIG) is a chronic condition in which the body's immune system mistakenly attacks the stomach lining, specifically targeting parietal cells that produce stomach acid and intrinsic factors. After the infection was eradicated, AIG developed in an elderly woman with symptoms of the disease. 1.

Natural olfactory systems possess remarkable sensitivity and precision beyond what is currently achievable by engineered gas sensors. Unlike their artificial counterparts, noses are capable of distinguishing scents associated with mixtures of volatile molecules in complex, typically fluctuating environments and can adapt to changes. This perspective examines the multifaceted biological principles that provide olfactory systems their discriminatory prowess, and how these ideas can be ported to the design of electronic noses for substantial improvements in performance across metrics such as sensitivity and ability to speciate chemical mixtures.

Introduction: Rhabdomyosarcoma (RMS) originates from undifferentiated mesenchymal cells that give rise to striated muscles. The symptoms of para-meningeal RMS often resemble those of allergic rhinosinusitis, including nasal congestion, mucus discharge, headache, and occasional nosebleeds. We report a child with atypical clinical presentation of ocular hypertropia secondary to para-meningeal RMS.

Evaluating the local immune microenvironment of the canine nasal cavity can be important for investigating normal tissue health and disease conditions, particularly those associated with local inflammation. We have optimized a technique to evaluate the local nasal immune microenvironment of dogs via serial nasal lavage. Briefly, with dogs under anesthesia and positioned in sternal recumbency, prewarmed sterile saline is flushed into the affected nostril using a flexible soft rubber catheter.

Fine particulate matter (PM2.5) is known to exacerbate chronic respiratory disorders, primarily by inducing inflammatory responses and mucus overproduction. Perilla leaves are reported to have significant health benefits, such as antioxidant, antibacterial, and antiallergic properties, attributed to phenolic compounds that vary depending on genetic diversity.
