Glomangiopericytoma of nasal cavity
Glomangiopericytoma/sinonasal type hemangiopericytoma is a rare sinonasal neoplasm arising from the pericytes surrounding capillaries and accounts for less than 0.5% of all sinonasal tumors. This tumor differs from conventional soft tissue hemangiopericytoma in location, biologic behaviour and histologic features.

Metastasizing esthesioneuroblastoma in a dog [PDF]
A 7-year-old Afghan hound presented with a history of disorientation, loss of vision, and seizures. Magnetic resonance imaging helped identify a mass at the level of the main olfactory bulb that compressed and displaced adjacent tissues in the cribriform

Schwannoma of the Nasal Cavity [PDF]
Schwannomas are benign peripheral nerve sheath tumors that occur throughout the body. They may present as either solitary or multiple masses. They rarely occur in the nasal cavity. The diagnosis is often made only after histologic examination. Because these lesions are radioresistant, the preferred treatment is complete surgical excision. We present a

Brain delivery of vasoactive intestinal peptide (VIP) following nasal administration to rats [PDF]
The aim of this work was to study in rats the nasal route for the brain delivery of the vasoactive intestinal peptide (VIP) neuropeptide. After evaluating VIP stability in solutions obtained from nasal washes, the effect of formulation parameters (pH 4-9,

Physical and geometric constraints explain the labyrinth-like shape of the nasal cavity
The nasal cavity is a vital component of the respiratory system that heats and humidifies inhaled air in all vertebrates. Despite this common function, the shapes of nasal cavities vary widely across animals.

Despite garnering minimal attention from the medical community overall, olfaction is indisputably critical in the manner in which we as humans interact with our surrounding environment. As the initial anatomical structure in the olfactory pathway, the nasal airway plays a crucial role in the transmission and perception of olfactory stimuli. The goal of
