Procentrioles in ciliating and ciliated cells of chick trachea

Zeitschrift f�r Zellforschung und Mikroskopische Anatomie, 1972
Electron 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 ...

Chemical Signaling in Ciliates

Journal of Eukaryotic Microbiology, 1995
ABSTRACT. 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 Microbiology
Endosymbiotic 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 ...

Flagellates and Ciliates

Clinics in Laboratory Medicine, 1999
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,

Flow patterns around ciliated microorganisms and in ciliated ducts

Journal of Theoretical Biology, 1982
Abstract 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.

Biotechnology in ciliates: an overview

Critical Reviews in Biotechnology, 2018
Desde su descripción y clasificación en el siglo XIX, los ciliados han desempeñado un papel importante en la ciencia, lo que ha llevado a varios descubrimientos fundamentales en las áreas de la biología celular y molecular. Durante las últimas décadas, con el surgimiento de la biotecnología, también están saliendo a la luz muchos nuevos desarrollos. En

The ciliated human keratinocyte

Journal of Ultrastructure Research, 1984
Human 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.

CILIATED ADENOCARCINOMA OF THE ENDOMETRIUM

Acta Obstetricia et Gynecologica Scandinavica, 1985
Abstract. Two cases of ciliated endometrial adenocarcino‐ma which came to attention in less than one year are described. This entity deserves emphasis, as its ciliation may distract from its histological malignant features. Association of cilia with atypical nuclear features in the same cell is the diagnostic characteristic which distinguishes it from

The Ciliates

1999
Abstract Balantidium coli belongs to the phylum Ciliophora of the kingdom Protista, which comprises all protozoa with cilia and mitochondria with tubular, often curved cristae, which in anaerobic species may be replaced by hydrogenosomes (Corliss, 1994).

On the evolution of the karyorelict ciliate life cycle: heterophasic ciliates and the origin of ciliate binary fission

Biosystems, 1991
Karyorelict ciliates have near diploid somatic nuclei (macronuclei) incapable of division. If selective pressure favors nuclear division, how could such macronuclei have evolved? I propose that they initially evolved in the context of a diplophase stage that consisted entirely of a non-dividing trophont that was terminated by the induction of meiosis ...
