Functional Outcomes Following Total Laryngectomy and Pharyngolaryngectomy: A 20-Year Single Center Study.

Background: Laryngeal cancer accounts for 1% of all cancers in men and 0.3% of all cancers in women. Pharyngolaryngectomy (TPL) and total laryngectomy (TL) are central surgical techniques in the management of advanced laryngeal malignancies but are associated with significant morbidity.

Morphological diversity within the Ozark minnow (Notropis nubilus: Leuciscidae).

The Ozark minnow, Notropis nubilus, is a small stream fish that has a disjunct distribution in the Ozark Plateau and upper Mississippi River basin. Three reciprocally monophyletic and deeply divergent lineages have been hypothesized within the species based on molecular data. These lineages are allopatric and isolated from each other.
