HSP90 Modulates T2R Bitter Taste Receptor Nitric Oxide Production and Innate Immune Responses in Human Airway Epithelial Cells and Macrophages.

Cells 2022 04 27;11(9). Epub 2022 Apr 27.

Department of Otorhinolaryngology-Head and Neck Surgery, Perelman School of Medicine, University of Pennsylvania, Philadelphia, PA 19104, USA.

Bitter taste receptors (T2Rs) are G protein-coupled receptors (GPCRs) expressed in various cell types including ciliated airway epithelial cells and macrophages. T2Rs in these two innate immune cell types are activated by bitter products, including those secreted by , leading to Ca-dependent activation of endothelial nitric oxide (NO) synthase (eNOS). NO enhances mucociliary clearance and has direct antibacterial effects in ciliated epithelial cells. Read More

Maxillary sinusitis caused by retained dental impression material: An unusual case report and literature review.

Niger J Clin Pract 2022 Apr;25(4):379-385

Department of Health Science, University of Florence, Florence, Italy.

Surgical procedures in posterior area of maxillary might cause an oroantral communication and iatrogenic sinusitis. An undetected oroantral communication can cause the penetration of foreign bodies, such as dental impression materials, in the maxillary sinus, thereby contributing to persistent sinusitis. Given the occurrence of a very rare clinical and medicolegal case of persistent and drug-resistant sinusitis due to radiologically undetected fragments of silicone paste for dental impression in the maxillary antrum, a literature review was pursued through sensitive keywords in relevant databases for health sciences.

Odontogenic Maxillary Sinusopathies: a Radiological Classification.

J Maxillofac Oral Surg 2022 Mar 16;21(1):141-149. Epub 2020 Jan 16.

Department of Translational Medicine, Otolaryngology, University of Rome "Tor Vergata", Via Montpellier,1, 00133 Rome, Italy.
