External Carotid Artery Ligation Versus Selective Artery Ligation in Transoral Surgery for Oropharyngeal Cancer.

Objective: Prophylactic ligation of the external carotid artery (ECA) during oropharyngeal squamous cell carcinoma (OPSCC) resection is known to reduce severe postoperative oropharyngeal bleeding events, however, there is limited research on whether bleed rates vary between selective ligation of individual vessels or total ligation of the ECA. This study assesses outcomes related to total versus selective ligation of the ECA in patients who underwent transoral resection for OPSCC of the base of tongue or palatine tonsils.

Study Design: Retrospective review.

Topological transition in filamentous cyanobacteria: from motion to structure.

Many active systems are capable of forming intriguing patterns at scales significantly larger than the size of their individual constituents. Cyanobacteria are one of the most ancient and important phyla of organisms that has allowed the evolution of more complex life forms. Despite its importance, the role of motility on the pattern formation of their colonies is not understood.

Association of Membranous Basal Cell Adenoma and Basal Cell Adenocarcinoma With Brooke-Spiegler Syndrome.

Basal cell adenoma (BCA) and basal cell adenocarcinoma (BCAC) are uncommon basaloid biphasic salivary gland tumors composed of basal and ductal cells. BCAC is differentiated from BCA by the presence of invasion in BCAC. In this paper, an 82-year-old woman presented with a palpable 3 cm immobile mass in her right parotid gland.

Evaluation of Non-Invasive Sampling Techniques for the Molecular Surveillance of Equid Herpesviruses in Yearling Horses.

Background: Equid alphaherpesvirus 1 (EHV-1) is a highly contagious respiratory tract pathogen of horses, and infection may be followed by myeloencephalopathy or abortion. Surveillance and early detection have focused on PCR assays using less tolerated nasal swabs. Here, we assess non-invasive non-contact sampling techniques as surveillance tools in naturally equid gammaherpesvirus 2-shedding horses as surrogates for EHV-1.
