The Harderian gland transcriptomes of Caraiba andreae, Cubophis cantherigerus and Tretanorhinus variabilis, three colubroid snakes from Cuba.

Genomics 2018 Nov 30. Epub 2018 Nov 30.

CIIMAR/CIMAR, Interdisciplinary Centre of Marine and Environmental Research, University of Porto, Terminal de Cruzeiros do Porto de Leixões, Av. General Norton de Matos, s/n, Porto 4450-208, Portugal; Department of Biology, University of Porto, Rua do Campo Alegre, s/n, Porto 4169-007, Portugal. Electronic address:

The Harderian gland is a cephalic structure, widely distributed among vertebrates. In snakes, the Harderian gland is anatomically connected to the vomeronasal organ via the nasolacrimal duct, and in some species can be larger than the eyes. The function of the Harderian gland remains elusive, but it has been proposed to play a role in the production of saliva, pheromones, thermoregulatory lipids and growth factors, among others.

[Intraoperative prevention of dacryocystitis relapse].

Vestn Oftalmol 2018 ;134(5. Vyp. 2):270-275

Research Institute of Eye Diseases, 11A Rossolimo St., Moscow, Russian Federation, 119021; I.M. Sechenov First Moscow State Medical University, Chair of Ophthalmology, 8-2 Malaya Trubetskaya St., Moscow, Russian Federation, 119991.

The article reviews the literature devoted to modern intraoperative methods of preventing cicatricial process at the site of dacryostoma after endonasal endoscopic dacryocystorhinostomy. Despite the constant improvement of the surgery technique, complications in the postoperative period still occur. They include the formation of granulation tissue at the sites of dacryostoma, synechiae in the nasal cavity, or narrowing of the dacryostoma, which ultimately leads to a relapse of the disease.

The nasolacrimal drainage apparatus (NDA) is of interest to anatomists, radiologists, and ophthalmologists alike, owing to its intricate luminal contour, complex surrounding structural morphology, and its clinical relevance. Here, we review the history of anatomical descriptions of so-called luminal "valves" of the NDA, including the numerous historical figures whose eponyms adorn the NDA. By 1908, multiple false "valves" that are likely no more than mounds of mucosa along the NDA had been recorded. Read More

Department of Radiology, Division of Neuroimaging and Neurointervention, Stanford University School of Medicine, Stanford, California.

Developmental remnants may follow segmental canalization of ectodermal epithelial cords forming the nasolacrimal drainage apparatus (NDA). This can result in false luminal "valves" along the path of the NDA, many of which have been named, but most have not been anatomically identified with consistency. By 1908, eight such "valves" were documented, those of: Foltz, Bochdalek, Rosenmüller, Huschke, Aubaret, Béraud or Krause, Taillefer, and Hasner or Cruveilhier or Bianchi. Read More
