Hemichordate worms possess ciliated gills on their trunk, and the homology of these structures with the pharyngeal gill slits of chordates has long been a topic of debate in the fields of evolutionary biology and comparative anatomy. Here, we show conservation of transcription factor expression between the developing pharyngeal gill pores of the hemichordate Saccoglossus kowalevskii and the pha...
Endothelin-1 (Edn1), originally identified as a vasoconstrictor peptide, is involved in the development of cranial/cardiac neural crest-derived tissues and organs. In craniofacial development, Edn1 binds to Endothelin type-A receptor (Ednra) to induce homeobox genes Dlx5/Dlx6 and determines the mandibular identity in the first pharyngeal arch. However, it remains unsolved whether this pathway i...
The male Siamese fighting fish, Betta splendens, builds a bubble nest on the water surface to care for offspring during the reproductive period. To our knowledge, this study is the first to determine the composition of the bubble nest and to compare the pharyngeal organs of male and female Siamese fighting fish to determine the relationship between the pharyngeal organ and the ability to make b...
BACKGROUND This study investigated the incidence and treatment outcomes of pharyngeal Neisseria gonorrhoeae and Chlamydia trachomatis cases at a Canadian clinic that mainly serves men who have sex with men. METHODS All patients with pharyngeal N. gonorrhoeae and C. trachomatis infections detected from 1 January 1995 through 31 December 2007 were identified. Original and test-of-cure N. gonorr...
AIM Cooling the pharynx and upper oesophagus would be more advantageous for rapid induction of therapeutic hypothermia since the carotid arteries run in their vicinity. The aim of this study was to determine the effects of pharyngeal cooling on brain temperature and the safety and feasibility for patients under resuscitation. METHODS Witnessed non-traumatic cardiac arrest patients (n=108) wer...
with reference to the morbid conditions of the ear, throat, and naso-pharynx. It is not without considerable diffidence that I make this further demand on your time and attention, fully conscious that I have no new facts or observations to offer for your consideration; that however attractive the study of these diseases may have been to myself, it cannot be expected that many of you will regard...
OBJECTIVE Anatomic narrowing of the pharyngeal airway increases the relative negative pressure generated during inspiration, thus affecting the dynamic behavior of the upper airway. The aim of this work was to measure pharyngeal area in snoring patients with and without obstructive sleep apnea (OSA), as categorized by polysomnography and by acoustic pharyngometry, and to analyze the different c...
