Unlike the NaCl-secreting salt glands of many birds and reptiles, the nasal salt glands of lizards can secrete potassium as well as sodium, with either chloride or bicarbonate as the accompanying anion. The factors responsible for initiating secretion by the gland and the rates of cation and anion secretion were studied in the desert iguana, Dipsosaurus dorsalis. Lizards were given combinations...
The posterior nasal nerves emerge from the sphenopalatine foramen and contain sensory and autonomic nerve components. Posterior nasal neurectomy is an effective method to remove pathological neural networks surrounding the inferior turbinate that cause unregulated nasal hypersensitivity with excess secretion in patients with severe allergic rhinitis (AR). We describe the sophisticated endoscopi...
To assess the acute effects of nasal continuous positive airway pressure (CPAP) on the 24-hour blood pressure and the secretion of catecholamines in urine and plasma, we investigated the changes in the 24-hour blood pressure and urinary and plasma concentrations of epinephrine (E) and norepinephrine (NE) in 26 men with obstructive sleep apnea (OSA) with and without nasal CPAP. Nasal CPAP result...
INTRODUCTION To evaluate the most sensitive symptom to predict early recurrence of nasal polyposis. Prospective longitudinal cohort study. Tertiary university referral center with accredited otorhinolaryngology residency programs. MATERIALS AND METHODS In this prospective study, we evaluated 62 patients with diffuse nasal polyposis. All patients underwent functional endoscopic sinus surgery. ...
In vitro toxicology approaches have evolved from a focus on molecular changes within a cell to understanding of toxicity-related mechanisms in systems that can mimic the in vivo environment. The recent development of three dimensional (3-D) organotypic nasal epithelial culture models offers a physiologically robust system for studying the effects of exposure through inhalation. Exposure to ciga...
Traditionally, nasal oxygen therapy has been delivered at low flows through nasal cannulae. In recent years, nasal cannulae designed to administer heated and humidified air/oxygen mixtures at high flows (up to 60 L/min) have been gaining popularity. These high-flow nasal cannula (HFNC) systems enhance patient comfort and tolerance compared with traditional high-flow oxygenation systems, such as...
Background: Oxytocin is a peptide hormone that increases the secretion of milk, especially after normal delivery. Due to the properties of this peptide hormone, it seems that changing the route of use and changing the release pattern can create a longer duration of action of the drug. Solid lipid nanoparticles (SLNs) are a candidate to achieve these goals, which can be used as a non-invasive me...
contagious agalactia (ca) is a serious disease syndrome of sheep and goats that is characterized by mastitis, arthritis, keratoconjunctivitis and, occasionally, abortion. mycoplasma (m.) agalactiae is the main cause of the disease in sheep and goats. the aim of the present study was to detect m. agalactiae in conjunctival, synovial fluid, nasal, ear and milk samples in sheep herds with or wi...
Responses in vitro to partially purified porcine leucocyte catabolin were studied in pig synovial fibroblasts.In serum-free cultures catabolin was found to stimulate secretion of prostaglandin E2 (PGE2) in a time and concentration-dependent manner. The initial stimulation of PGE2 secretion occurred only after a latent interval of six hours. In the same cell line catabolin was found to have no e...
