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 ...

This article includes information on two human parasites, one protozoan flagellate, Giardia lamblia, and one ciliate, Balantidum coli. Both are transmitted through ingestion of food and water contaminated with fecal material. G. lamblia may be the most common intestinal protozoan found in humans throughout the world and causes a wide range of symptoms,

Ciliate Telomerase Biochemistry
Annual Review of Biochemistry, 1999▪ Abstract Telomerase is a cellular reverse transcriptase specialized for use of a template carried within the RNA component of the enzyme ribonucleoprotein complex. Substrates for telomerase are single-stranded oligonucleotides in vitro and chromosome ends in vivo.

To the Editor.— Farmer and Helwig 1 described 11 female patients with cutaneous ciliated cysts in the lower extremities. They quoted only two previously reported cases. The first patient described by Hess in 1890 2 was a 15-year old-girl with a ciliated cyst situated over the fourth or fifth thoracic vertebra and because of this anatomic situation ...

The ciliated human keratinocyte
Journal of Ultrastructure Research, 1984Human keratinocytes were investigated for the presence of single cilia. Almost all basal keratinocytes were found to carry a single cilium in normal, occluded, and psoriatic skin. The ciliary structure was progressively reduced in keratinocytes approaching the surface. No remnants of the ciliary apparatus were found in the granular layer.

Publisher Summary Rumen protozoa were first observed in rumen metabolism. These ciliate protozoa are present in all wild and domesticated ruminants and are of two types: the entodiniomorphid protozoa characterized by the presence of a firm pellicle and the possession of cilia on the peristome and the holotrich protozoa, which are completely covered ...

Subhepatic ciliated foregut cyst
Annals of Diagnostic Pathology, 2005Foregut cyst derives from the primitive foregut and occurs in the tracheobronchial tree, mediastinum, liver, pancreas, tongue, and upper digestive tract. We report the first case of a foregut cyst in the subhepatic area. A computed tomographic scan of a 45-year-old man with dull backache showed a discrete subhepatic multiloculated cystic lesion.

This study describes a solitary unilocular cyst of the liver, lined by ciliated, pseudostratified, columnar epithelium supported by a loose, relatively acellular lamina propria. The cyst wall was composed of a prominent smooth muscle band, of up to three layers, surrounded by an outer fibrous capsule.
