Ciliated Carcinoma of the Endometrium
International Journal of Gynecological Pathology, 2020We report a case of ciliated carcinoma of the endometrium in a 55-yr-old woman with stromal hyperthecosis of the ovaries. The patient presented with postmenopausal uterine bleeding and an endometrial curetting revealed an atypical epithelial proliferation that met the criteria for endometrioid adenocarcinoma notwithstanding an abundance of ciliated ...

Chapter 59 Electrophysiology of Ciliates
1995Publisher Summary Ciliated protozoa provide excellent systems to study the roles of electrical currents in behavioral responses of protozoan and metazoan cells because their swimming behavior-whether they swim forward, backward, or are arrested in one place-depends directly on the concentration of Ca 2+ ions within the axoneme.

Control of ciliation in embryogenesis
Nature Cell Biology, 2015The protrusion of cilia into extracellular space provides cells with sensors of localized environmental cues that include fluid flow, mechanical force and important growth factors such as Hedgehog. Live imaging has now captured the initial appearance of cilia during embryogenesis, and defined lineage-specific determinants that restrict extra-embryonal ...

Holotrich ciliate protozoa have been observed frequently in samples obtained from the principal fermentative regions in the digestive tracts of herbivorous mammals. The descriptive term “holotrich” initially arose from the terminology used in the original major systems of protozoal classification. Prior to the taxonomic revisions of Levine et al. (1980)

We report the case of a presternal ciliated cyst in a 39-year-old man. The location and histologic features of this lesion have led us to favor a primitive foregut origin for this cyst, probably via the process of embryonic sequestration and migration.

The Genome of Hypotrichous Ciliates
1986Publisher Summary This chapter discusses the genome of hypotrichous ciliates. The chapter describes the structure of the macronucleus as well as the cytological and molecular events during macronuclear differentiation. Similar to the majority of ciliated protozoa, hypotrichous ciliates are characterized by their nuclear dimorphism.

Publisher Summary The colonization of nuclei by prokaryotic or eukaryotic microbes is frequently observed, especially in ciliates. This chapter discusses endonucleobiosis, in which the nucleus is specific and exclusive site of residence of guest organisms. The colonizing microbes are referred as endonucleobionts. All endonucleobionts in ciliates live

Living cells share the ability to react to environmental stimuli, such as touch, light, chemicals or temperature. During stimulus reception, external energy is translated and amplified into electrical signals by means of physicochemical processes.

Ectosymbiosis in Ciliated Protozoa
2001The picture of the ectosymbiotic associations between ciliates and bacteria that can be drawn from this paper is complex, although, in all likelihood, it is far from complete: other different, as yet undiscovered relationships may exist. From the ecological point of view these kinds of associations certainly contribute to the differentiation of the ...

Mitochondrial Genomes of the Ciliates
1992Publisher Summary This chapter describes the mithochondrial genome of ciliates, with emphasis on Paramecium and Tetrahymena . Both Paramecium and Tetrahymena have linear genomes with unique replicative pathways. The mitochondrial genome of Paramecium aurelia is a linear duplex.
