Efficient vaccine delivery to mucosal tissues including mucosa-associated lymphoid tissues is essential for the development of mucosal vaccine. We previously reported that claudin-4 was highly expressed on the epithelium of nasopharynx-associated lymphoid tissue (NALT) and thus claudin-4-targeting using C-terminal fragment of Clostridium perfringens enterotoxin (C-CPE) effectively delivered fus...
In this study, we demonstrated a new airway Ag sampling site by analyzing tissue sections of the murine nasal passages. We revealed the presence of respiratory M cells, which had the ability to take up OVA and recombinant Salmonella typhimurium expressing GFP, in the turbinates covered with single-layer epithelium. These M cells were also capable of taking up respiratory pathogen group A Strept...
the main issues in nasal surgery are to stabilize the nose in the good position after surgery and preserve the cartilages and bones in the favorable situation and reduce the risk of deviation recurrence. also it is necessary to avoid the synechia formation, nasal valve narrowing, hematoma and bleeding. due to the above mentioned problems and in order to solve and minimize them nasal packing, na...
introduction rhinoliths are uncommon nasal masses. they are mineralized masses found within the nasal cavity. they have various clinical presentations. case presentation we report a 13-year-old boy with long-standing nasal obstruction, yellowish nasal discharge and intermittent and minimal nasal bleeding for a few weeks, who had been treated as rhinosinusitis twice. due to the presence of long-...
in crooked noses, the lateral walls are different in shape and symmetry. although the septum is very important to obtain a straight nose, identical and symmetrical lateral walls are needed for a straight looking nasal dorsum. as well as the septum, lateral walls also contribute in nasal skeletal support and stability. thus, obtaining identical and symmetrical lateral walls is important. in orde...
background: influenza outbreak has become a great lifethreateningdisease in the world. nasal vaccines can inducesystemic igg and mucosal iga antibody responses, whichestablish two layers of immune defense against the infectiouspathogens like influenza. mucosal vaccines must overcomeseveral limitations, including the mucociliary clearance andinefficient uptake of soluble antigens. therefore, nas...
background: nasal continuous positive airway pressure (ncpap) is an effective method of ventilation in newborns with respiratory distress syndrome (rds). using an appropriate nasal skin care protocol is identical to prevention or reduction of nasal skin breakdown in those who receive ncpap. this study aimed to investigate the effectiveness of an evidence-based clinical care protocol on nasal sk...
هدف: این مطالعه به منظور بررسی نتایج nasal tip augmentation با استفاده از غضروف اتوژن در مراجعین به مراکز جراحی تخصصی شهر تهران و بیمارستان بوعلی طی سال های 88-89 انجام شده است. روش مطالعه: 36 فرد تحت nasal tip augmentation با استفاده از غضروف اتوژن در این مطالعه مورد بررسی قرار گرفتند که نتایج به دست آمده و میزان رضایتمندی در بیماران مشخص گردید و ارتباط فاکتورهای دموگرافیک با آن ارزیابی شد. ...
BACKGROUND Many infectious diseases that cause significant morbidity and mortality, especially in the developing world, could be preventable through vaccination. The effort to produce safe, thermally stable, and needle-free mucosal vaccines has become increasingly important for global health considerations. We have previously demonstrated that a thermally stable nanoemulsion, a mucosal adjuvant...
