Although the respiratory system signs are usually the most important, several signs related to pathology in other tissues
with ciliated epithelia or microtubules can occur, such as otitis media, infertility in males and females, hydrocephalus, and renal fibrosis or dilation of renal tubules.
Thinking back to the Mass we recall the smallest things — yellow neckties splashed
with ciliated paisley, old silk dresses with piscine flares, and one thin strand of cultured pearls.

PhD student Dorothea Gilbert has been responsible for the tests
with the ciliate Tetrahymena pyriformis.

Scanning electron microscope photograph of the
ciliate Tiarina
with its 100 - 150 micrometer calcium carbonate (calcareous) shell containing the Symbiodinium cells (not visible here).
They used two different groups of resident species consisting of aquatic bacteria,
ciliates — protozoans
with hair - like projections called cilia — and rotifers, organisms
with cilia - laced mouths and retractable feet.
Our experiments demonstrate that motile microorganisms such as Tetrahymena pyriformis swim actively
with the PAHs, and it is important to notice that the
ciliates can swim faster than PAHs can be transported by means of diffusion.
Together
with Professor Philipp Mayer, who is presently employed at the Technical University of Denmark (DTU), she has developed a new test setup that allows exposing the
ciliates to a concentration gradient while concurrently enabling their observation through a microscope in real time and measuring the transport of PAH by means of chromatographic methods.
This is connected
with the fact that more PAH is incorporated into the
ciliates» lipid cell membrane, the more hydrophobic the PAHs» says Dorothea Gilbert.
Ciliates 18S rRNA genes were amplified
with an un-nested PCR approach.

with permission) As the level of oxygen in the atmosphere rose, however, most surface lifeforms on Earth became oxygen breathing, such as these two single - celled protoctists (Euplotes, left, and Stylonychia) which move
with hairlike cilia.
Infection
with human rhinovirus, the most common cause of asthma exacerbation in adults and children, was restricted to
ciliated cells and resulted in
ciliated cell apical sloughing and goblet cell hyperplasia, replicating hallmarks of cytopathology observed in vivo.
INX - 4:: GFP does not appear to be expressed in neurons implicated in locomotion, but is expressed in a number of
ciliated neurons, pharyngeal m1 muscle cells, and the RIP neurons that form gap junctions
with pharyngeal I1 neurons (Figure 5E).
Examination by transmission electron microscopy is required to see that, in contrast to a cycliophoran, the
ciliate consists of just a single cell
with several nuclei.
