A Novel Bionebulizer Approach to Study the Effects of Natural Mineral Water on a 3D In Vitro Nasal Model from Allergic Rhinitis Patients.

Sulfurous thermal waters (STWs) are used as a complementary treatment for allergic rhinitis. However, there is scant data on the effects of STW on nasal epithelial cells, and in vitro models are warranted. The main aim of this study was to evaluate the dose and time effects of exposure to 3D nasal inserts (MucilAirTM-HF allergic rhinitis model) with STW or isotonic sodium chloride solution (ISCS) aerosols. Transepithelial electrical resistance (TEER) and histology were assessed before and after nebulizations. Chemokine/cytokine levels in the basal supernatants were assessed by enzyme-linked immunosorbent assay. The results showed that more than four daily nebulizations of four or more minutes compromised the normal epithelial integrity. In contrast, 1 or 2 min of STW or ISCS nebulizations had no toxic effect up to 3 days. No statistically significant changes in release of inflammatory chemokines MCP-1/CCL2 > IL-8/CXCL8 > MIP-1α/CCL3, no meaningful release of "alarmins" (IL-1α, IL-33), nor of anti-inflammatory IL-10 cytokine were observed. We have characterized safe time and dose conditions for aerosol nebulizations using a novel in vitro 3D nasal epithelium model of allergic rhinitis patients. This may be a suitable in vitro setup to mimic in vivo treatments of chronic rhinitis with STW upon triggering an inflammatory stimulus in the future.

New species and records in Phrynidius Lacordaire (Coleoptera, Cerambycidae, Lamiinae).

Phrynidius Lacordaire, 1869, a genus of Mesoamerican distribution, is a group whose original taxonomic knowledge was generally limited, mainly due to the original descriptions not allowing for the adequate determination of its species. Recently, this knowledge was increased with the description of new species and the publication of a key to separate them. However, this knowledge is still incomplete, and there remain undescribed species deposited in different entomological collections. In this study, we update the taxonomic and distributional knowledge of the genus, and provide a new key to separate the species. Seven new species are described: P. poriferus sp. nov., from Honduras; P. skillmani sp. nov., from Guatemala; P. obrieni sp. nov., from Honduras; P. wibmeri sp. nov., from Mexico; P. pallifemoralis sp. nov., from Mexico; P. oaxacanensis sp. nov., from Mexico; P. guatemalensis sp. nov., from Guatemala. Phrynidius echinus Bates, 1880 is briefly redescribed and reported for the first time for the Guatemalan department of El Progreso. Phrynidius armatus Linsley, 1933 is excluded from the Nicaraguan fauna. Additionally, two new country records are reported: Phrynidius guifarroi Santos-Silva, Van Roie & Jocqu, 2021, from Guatemala; and P. nayaritensis Heffern, Nascimento & Santos-Silva, 2018, from Honduras.

Descriptions, notes, and a new record in Oideterus Thomson (Coleoptera, Cerambycidae, Prioninae, Anacolini).

The male of Oideterus elegans (Waterhouse, 1880) is described for the first time, female chromatic variations are reported, and the species is recorded from the Ecuadorian department of Napo. Two new species are described from Ecuador: Oideterus leoninus and O. ecuadorensis. The species-group name of O. nigrum Botero, Galileo Santos-Silva, 2019 is corrected. Identification keys to males and females of Oideterus species are provided.

Neoxela: A new replacement name for Xela Botero, Bezark amp; Santos-Silva, 2020 (Coleoptera, Cerambycidae, Lamiinae).

Recently, Botero, Bezark Santos-Silva (2020) described a new genus of Methiini (Cerambycinae), Xela, for their new species Xela tysoni, from Guatemala. Currently, the genus remains monotypic and the species is known only from their type locality. Unfortunately, the authors did not realize that the name had already been used for a trilobite species (Xela drena Jell, 1990). Herein, we propose a new replacement name for the genus.
