hNECs undergo EMT during hypoxia and this process is critically mediated by HIF-1α and pSmad3. This study shows that hypoxia-induced EMT is likely to contribute to nasal polyposis in CRS, and suggests that HIF-1α be viewed as a therapeutic target for nasal polyposis.
It is likely that BPPV after TBI is more difficult to treat than idiopathic BPPV, but no tendency to recur was observed in patients who developed BPPV after TBI compared with idiopathic BPPV. Further prospective clinical meta-analytic studies are needed to investigate the outcome of BPPV after TBI.
Using mechanical injury, the wound healing model of the nasal mucosa was established in a rat. The regeneration of respiratory mucosa was completed on day 28 after injury.
Olfactory impairment is not common after use of the NSF. Use of the cold knife in making superior incision may reduce tissue damage with better olfactory outcomes.
Preoperative CT findings, especially the anterior portion of the olfactory cleft, had a statistically significant association with the postoperative olfactory results in patients with CRS with nasal polyps.
Resveratrol may be useful for the prevention of eosinophilic CRSwNP. A key mechanism of its action is believed to be its anti-inflammatory effect, particularly on eosinophils, by inhibiting the lipoxygenase pathway.
Resection of the submental type dermoid cyst can be performed by an intraoral endoscope-assisted approach through the floor of the mouth. We describe the procedure of the endoscope-assisted intraoral resection.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
