Survival Rate and Growth of Fighting Fish Larvae (Betta splendens Regan) Fed on Various Live Foods

open access: yesJurnal Akuakultur Indonesia, 2007
Larval of fighting fish (Betta splendens Regan) requires precise live foods for its growth and survival. In this experiment, fish larvae were fed on either Paramecium + Artemia, Paramecium + Artemia + Tubifex, Paramecium + Moina, or Paramecium + Moina +

Density-and trait-mediated effects of a parasite and a predator in a tri-trophic food web [PDF]

open access: yes, 2014
1. Despite growing interest in ecological consequences of parasitism in food webs, relatively little is known about effects of parasites on long-term population dynamics of non-host species or about whether such effects are density- or trait- mediated ...

New Intranuclear Symbiotic Bacteria from Macronucleus of Paramecium putrinum—“Candidatus Gortzia Yakutica”

open access: yesDiversity, 2020
Holospora-like bacteria (HLB) are obligate intracellular Alphaproteobacteria, inhabiting nuclei of Paramecium and other ciliates such as “Candidatus Hafkinia” is in Frontonia.

RNA interference reveals the escape response mechanism of Paramecium to mechanical stimulation

open access: yesBiophysics and Physicobiology, 2023
In Paramecium, a mechanical stimulus applied to the posterior portion of the cell causes a transient increase in membrane permeability to potassium ions, transiently rendering the membrane in a hyperpolarized state.

Photosynthesis dependent acidification of perialgal vacuoles in theParamedum bursaria/Chlorella symbiosis. Visualization by monensin [PDF]

open access: yes, 1992
After treatment with the carboxylic ionophore monensin theChlorella containing perialgal vacuoles of the greenParamecium bursaria swell. TheParamecium cells remain motile at this concentration for at least one day.

Pdsg1 and Pdsg2, novel proteins involved in developmental genome remodelling in Paramecium. [PDF]

open access: yesPLoS ONE, 2014
The epigenetic influence of maternal cells on the development of their progeny has long been studied in various eukaryotes. Multicellular organisms usually provide their zygotes not only with nutrients but also with functional elements required for ...

Spontaneous creation of macroscopic flow and metachronal waves in an array of cilia [PDF]

open access: yes, 2006
Cells or bacteria carrying cilia on their surface show many striking features : alignment of cilia in an array, two-phase asymmetric beating for each cilium, coordination between cilia and existence of metachronal waves with a constant phase difference ...

Using Paramecium as a Model for Ciliopathies [PDF]

open access: yesGenes, 2021
Paramecium has served as a model organism for the studies of many aspects of genetics and cell biology: non-Mendelian inheritance, genome duplication, genome rearrangements, and exocytosis, to name a few. However, the large number and patterning of cilia that cover its surface have inspired extraordinary ultrastructural work.

Evolution of the Exon-Intron Structure in Ciliate Genomes. [PDF]

open access: yesPLoS ONE, 2016
A typical eukaryotic gene is comprised of alternating stretches of regions, exons and introns, retained in and spliced out a mature mRNA, respectively.

Finding the ciliary beating pattern with optimal efficiency [PDF]

open access: yesProc. Natl. Acad. Sci. USA 108: 15727-15732 (2011), 2011
We introduce a measure for energetic efficiency of biological cilia acting individually or collectively and numerically determine the optimal beating patterns according to this criterion. Maximizing the efficiency of a single cilium leads to curly, often symmetric and somewhat counterintuitive patterns.
