Surgical Neurology, 1985
A tumor of Rathke's cleft origin was studied, which showed some histologic features consistent with craniopharyngioma, but also had ciliated and mucin-containing cells more commonly observed in Rathke's cleft cysts. The combination of features provides further evidence that craniopharyngiomas and Rathke's cleft cysts have a common embryonic origin.

Our understanding of the biology of ciliate pheromones, and of the primary functions of the mating-type mechanism regulated by these molecules, has given rise to radical conflicts of opinion among different investigators, as regards interpretation of phenomena, definition of basic concepts, and use of terminology.

Abstract The occurrence of cilia in endometrim that is normal, hyperplastic, atrophic, and adenocarcinomatous has been studied. Cilia are frequent in normal cyclic endometria and in hyperplastic endometria, are less frequent in those exhibiting atrophy, and are rare in carcinomatous endometria.

Mixotrophy is the occurrence of phagotrophy and phototrophy in the same organism. In ciliates the intracellular phototroph can be unicellular green algae (zoochlorellae), dinoflagellates (zooxanthellae), cryptomonads or sequestered chloroplasts from ingested algae.

Chemical Signaling in Ciliates
Journal of Eukaryotic Microbiology, 1995ABSTRACT. For long, our knowledge of the biology of ciliate pheromones has long relied solely upon the study of the two structurally unrelated “gamones” identified in culture filtrates of a Blepharisma species. However, the characterization of a number of polypeptide pheromones secreted by Euplotes raikovi and E. octocarinatus has now established that

Symbionts of Ciliates and Ciliates as Symbionts
Indian Journal of MicrobiologyEndosymbiotic relationships between ciliates and others are critical for their ecological roles, physiological adaptations, and evolutionary implications. These can be obligate and facultative. Symbionts often provide essential nutrients, contribute to the ciliate's metabolism, aid in digestion, and offer protection against predators or environmental ...

Flow patterns around ciliated microorganisms and in ciliated ducts
Journal of Theoretical Biology, 1982Abstract Microscopic organisms and tracts of ciliated epithelia often generate complicated flow patterns such as eddies or jet-like phenomena. In addition, the presence of boundaries (e.g. microscope slide or coverslip) may also influence or severely restrict the resulting fluid motion.

Procentrioles in ciliating and ciliated cells of chick trachea
Zeitschrift f�r Zellforschung und Mikroskopische Anatomie, 1972Electron microscopy of 16 to 18 day old chick tracheas revealed that procentrioles are present near the basal ends of the recently matured centrioles and basal bodies of both ciliating and ciliated cells. Cylinders 0.1 μ in outside diameter in which densely staining walls and a central axial filament can often be detected, are present between the ...

Ciliate evolution: The ribosomal phylogenies of the tetrahymenine ciliates
Journal of Molecular Evolution, 1989We have assembled and analyzed nucleotide sequences for several different rRNA components from tetrahymenine ciliates. These include previously published and some new 5S and 5.8S rRNAs for a total of 18 species. We also report sequences for some 30 species obtained by primer extension analysis of a region near the 5' end of the 23S rRNAs (region 580 ...
