Chewing lice of wild birds in Iran: new data and a checklist of avian louse species reported in Iran
Between September 2019 and December 2023, a total of 612 wild birds representing 16 orders, 33 families, 60 genera, and 78 species from nine provinces of Iran with different climates namely Hamedan (n =โ54), Sistan-va-Baluchestan (n =โ372), Kerman (n =โ73), South Khorasan (n =โ52), Mazandaran (n =โ7), Chaharmahal-va-Bakhtiari (n =โ2), Gilan (n =โ2), Golestan (n =โ18), North Khorasan (n =โ9), and Razavi Khorasan (n =โ23) were examined for chewing lice infestation. Naked eye examination revealed that 58 birds (9.5%) were infested with at least one chewing louse species. Collected lice specimens belonged to 28 species from the families Philopteridae, Menoponidae and Laemobothriidae including Strigiphilus strigis (n =โ55, 15.6%), Falcolipeurus quadripustulatus (n =โ41, 11.6%), Craspedorrhynchus platystomus (n =โ40, 11.3%), Colpocephalum turbinatum (n =โ36, 10.2%), Laemobothrion maximum (n =โ25, 7.1%), Nosopon lucidum (n =โ20, 5.6%), Degeeriella fulva (n =โ18, 5.1%), Colpocephalum eucarenum (n =โ16, 4.5%), Laemobothrion vulturis (n =โ15, 4.2%), Anaticola crassicornis (n =โ13, 3.7%), Craspedorrhynchus aquilinus (n =โ9, 2.5%), Degeeriella fusca (n =โ7, 2.0%), Aegypoecus trigonoceps (n =โ7, 2.0%), Quadraceps obscurus (n =โ6, 1.7%), Colpocephalum impressum (n =โ6, 1.7%), Trinoton querquedulae (n =โ6, 1.7%), Colpocephalum heterosoma (n =โ5, 1.4%), Colpocephalum nanum (n =โ5, 1.4%), Lunaceps holophaeus (n =โ4, 1.1%), Quadraceps spp. (n =โ4, 1.1%), Actornithophilus uniseriatus (n =โ2, 0.6%), Nosopon chanabense (n =โ2, 0.6%), Actornithophilus cornutus (n =โ1, 0.3%), Cuclotogaster heterographus (n =โ1, 0.3%), Falcolipeurus suturalis (n =โ1, 0.3%), Laemobothrion atrum (n =โ1, 0.3%), Colpocephalum gypsi (n =โ1, 0.3%), and Rallicola cuspidatus (n =โ1, 0.3%). All of these species except six, i.e., Trinoton spp., C. aquilinus, L. vulturis, L. maximum, C. impressum, C. turbinatum, and C. heterographus are recorded for the first time from Iran. This study is the largest epidemiological study to date performed in the country. Data reported herein contribute to our knowledge about diversity of avian chewing lice from wild birds in Iran.

3D-Printed Soft Membrane for Periodontal Guided Tissue Regeneration
Objectives: The current study aimed to perform an in vivo examination using a critical-size periodontal canine model to investigate the capability of a 3D-printed soft membrane for guided tissue regeneration (GTR). This membrane is made of a specific composition of gelatin, elastin, and sodium hyaluronate that was fine-tuned and fully characterized in vitro in our previous study. The value of this composition is its potential to be employed as a suitable replacement for collagen, which is the main component of conventional GTR membranes, to overcome the cost issue with collagen. Methods: Critical-size dehiscence defects were surgically created on the buccal surface of the roots of canine bilateral mandibular teeth. GTR treatment was performed with the 3D-printed membrane and two commercially available collagen membranes (Botiss Jasonยฎ and Smartbrane-Regedent membranes) and a group without any membrane placement was considered as the control group. The defects were submerged with tension-free closure of the gingival flaps. Histologic and histometric analyses were employed to assess the periodontal healing over an 8-week experimental period. Results: Histometric evaluations confirmed higher levels of new bone formation in the 3D-printed membrane group. Moreover, in all defects treated with the membranes, the formation of periodontal tissues, bone, periodontal ligaments, and cementum was observed after 8 weeks, while in the control group, only connective tissue was found in the defect sites. There was no clinical sign of inflammation or recession of gingiva in any of the groups. Significance: The 3D-printed gelatin/elastin/sodium hyaluronate membrane can be safe and effective for use in GTR for periodontal tissue regeneration therapies, with better or comparable results to the commercial collagen membranes
