The AA. examine in the present work the main syndrome of I and II branchial arch, valuing the hetiopathogenetic and clinic aspects and determining a diagnostic-differential scheme between the same. It is underlined the importance of the echografic exam for the prenative diagnosis and the clinic exam for the after native diagnosis.

Introduction And Importance: The branchial or pharyngeal apparatus, crucial in embryological development, consists of clefts, arches, pouches, and membranes. Anomalies arising from this apparatus particularly involving the second branchial arch, are rare. Among these anomalies, complete second branchial cleft fistulas, with both external and internal openings, are exceptionally uncommon.

Acute suppurative thyroiditis (AST), a rare yet potentially life-threatening infection, comprises less than 1 % of neck pathologies and requires prompt treatment. Symptoms range from neck pain and fever to dysphagia and possible abscess formation. Broad-spectrum antibiotics are the primary treatment; however, surgical drainage may be necessary for abscesses to prevent systemic infection.

A core framework of the gene regulatory network (GRN) governing neural crest (NC) cell development has been generated by integrating separate inputs from diverse model organisms rather than direct comparison. This has limited insights into the diversity of genes in the NC cell GRN and extent of conservation of newly identified transcriptional signatures in cell differentiation and invasion. Here, we address this by leveraging the strengths and accessibility of the avian embryo to precise developmental staging by egg incubation and use an integrated analysis of chick (HH13) and mouse (E9.

The Y-organs (YOs) synthesize and secrete molting hormones, and thus regulate crustacean growth and reproduction. However, the YOs of the orange mud crab Scylla olivacea is yet to be described due to its minute size and ambiguous feature. This study describes the location, morphological characteristics, histology, and the changes of YOs at different molt stages, and examines in vitro ecdysteroid secreted by the YOs of S.

A new species of beardfish, genus , is described based on three specimens collected in Taiwanese waters and off the Chesterfield Islands of New Caledonia. It can be distinguished from its congeners by the following characters: dorsal-fin rays IV-V, 35-37; gill rakers on outer face of first gill arch 3+1+6=10; scales row between dorsal-fin origin and lateral line vertically 6-8 (S1) and posteriorly 12-14 (S2); pyloric caeca 40; snout rounded, with its surface rough and gelatinous, its tip evidently protrude anterior margin of premaxilla; ctenii on body scales arranged in a wedge-shape, forming three rows; 4 anal-fin spine long, 1.0%-1.
